Description

  The present invention relates to a mechanism of an oil recovery section of a recovery device that recovers oil that has flowed out and leaked into underground soil.

  Oils such as crude oil, heavy oil, and light oil that have leaked and leaked into the underground soil diffuse through the permeable layer through which the groundwater flows in the soil, and the contamination of the groundwater by these oils spreads.

  In order to purify the groundwater contamination by this oil, it is desired to efficiently recover it with a simplified apparatus.

  Conventionally, as a means for collecting these spilled oils, an oil removing device including a belt-like adsorbent, a travel drive unit, and a separation and collection unit is known.

  The belt-like adsorber configured in this oil removing apparatus is wound endlessly between a plurality of rollers, and circulates between the lower end side of the excavation hole and the ground.

  The traveling drive unit is installed on the ground side, and includes a motor that is axially connected to the top roller, and a drive source for the motor.

  Further, the separation collection unit is also installed on the ground side, and is composed of a nipping roller and a collection tank. This nipping roller is installed below the top roller and sandwiches the adsorbent that circulates with the top roller. This is a device for releasing the oil by squeezing and holding down the oil adsorbed and held on the adsorption mat of the adsorbent (see, for example, Patent Document 1).

  In addition, there are other oil recovery devices equipped with moving wheels.

This oil recovery device suspends an endless belt in a rotatable state on a carriage that can move on the floor, and rotates the endless belt on this carriage and the oil attached to the endless belt from the endless belt. A recovery device for recovery is known (see, for example, Patent Document 2).
Japanese Patent Laid-Open No. 10-314714 JP 2004-8964 A

  However, those described in Patent Documents 1 and 2 use an endless belt (adsorbent), are supported by a plurality of rollers, and are rotationally driven to circulate. However, there is a problem that it takes time to collect sticky oil such as crude oil and heavy oil.

  In addition, it is difficult to recover a highly viscous oil such as C heavy oil.

  The present invention solves the above-described conventional problems, and simplifies the configuration of the recovery device to improve low noise and durability, and also has viscous oil such as crude oil and heavy oil that has leaked into and leaked into underground soil. An object of the present invention is to provide an oil recovery mechanism member of an oil recovery apparatus that can efficiently recover (especially C heavy oil).

  The present invention has a capturing body having a certain length, a weight is provided at a tip of the capturing body, and when the capturing body is lowered by an electric rotating body, viscous oil is captured by the capturing body. When the trapping body rises above the oil level of the viscous oil by the electric rotating body, the oil separating means of the oil recovery device installed on the ground causes the viscous oil attached to the trapping body to be attached. In the oil recovery apparatus for separating and recovering, the oil separation means has a mechanism for scraping off the viscous oil adhering to the capturing body.

  According to the oil recovery mechanism member of the present invention, by simplifying the configuration of the recovery device and minimizing the number of members that generate noise such as a rotating roller, it is possible to improve low noise and durability, It is possible to arbitrarily cope with various situations such as the position of the floating liquid level, and to effectively remove and collect the viscous oil adhering to the capturing body.

The first invention is inserted into a drilling hole excavated to the permeable layer through which underground soil and groundwater flow, a cylindrical body inserted into the drilling hole, and a passage formed in the cylindrical body, and has a certain length. A capture body having one end of the capture body, a winding unit that winds up the capture body, a rotating body that has the winding unit, and a drive unit that rotationally drives the rotary body forward and backward. and, wherein the other end of the captor are equipped weight is, the rotation of the rotating body, is first lowered the capturing body as the weight reaches the aquifer, then the capturing body upward The viscous oil is attached to the capturing body when winding up, and when the capturing body rises above the oil surface of the viscous oil, the oil is separated and recovered by the oil separating means of the oil recovery device installed on the ground. In the oil recovery apparatus, the oil separating means removes the viscous oil adhering to the capturing body. It is obtained by the technique drop mechanism.

  This simplifies the configuration of the oil recovery device to improve low noise and durability, as well as responding arbitrarily to various situations such as the position of the liquid surface where the viscous oil floats, and the viscous oil attached to the trapping body Can be removed and recovered efficiently.

Specifically, the trapping body is a flexible wire, and the viscous oil attached to the trapping body is wound up by operating the electric rotating body, so that the viscous oil is collected in the oil recovery device installed on the ground. Since the scraping mechanism has a V shape or a brush shape that sandwiches the capturing body, the viscous oil can be efficiently separated and the separated viscous oil can be recovered.
Further, the moving distance for moving the capturing body up and down can be easily set by switching the rotation direction of the forward rotation or reverse rotation of the rotating body drive means and controlling the rotation speed or rotation angle.
Furthermore, a large number of holes or slits are formed in the lower part of the cylindrical body located in the water permeable layer so that groundwater and viscous oil can sufficiently enter and pass therethrough.

  Also, the part where the trapping body and the mechanism that scrapes the viscous oil come into contact with each other is subject to wear and metal fatigue, so the material of the mechanism that scrapes the viscous oil is made of fluorine-containing resin, fluorine-containing rubber, molybdenum By using any one of the contained stainless steels, the durability of the capturing body can be improved, and the viscous oil can be recovered stably.

  Furthermore, the viscosity oil can be reduced without causing the viscous oil to ignite by setting the mechanism for scavenging the viscous oil to 40 ° C to 50 ° C with heating means by heat conduction. Can be removed.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a partial side sectional view of an oil recovery apparatus, and FIG.

1 and 2, a fixing plate 2 is provided inside the housing 1, and a rotating body 3 having a winding part 3 a is provided on the fixing plate 2. The rotating body 3 is directly adjusted by a geared motor 4 (driving means). Conversely, it is rotationally driven.

  A detecting means 3b using a proximity sensor, a magnetic sensor, an optical sensor, or the like that detects the number of rotations or the rotation angle of the rotating body 3 is provided facing the rotating body 3, and this detecting means 3b and the geared motor 4 (driving means). Is connected to the control means 4a.

  This control means 4a performs rotational drive control of forward and reverse rotation of the rotating body 3.

  One end of a flexible wire 5 is connected to the winding portion 3a, and a weight 6 is attached to the other end portion.

  The rotating body 3 and the geared motor 4 (driving means) constitute a vertically moving means. The geared motor 4 that is the driving means may be a stepping motor.

  A passage 8 is formed inside the cylindrical body 7, and a wire 5 is inserted into the passage 8. In addition, a collector 9 that is a separating means for sandwiching the wire 5 and separating the viscous oil attached to the wire 5 is fixed to the fixed plate 2.

  Moreover, the contact part of the collector 9 and the wire 5 is V-shaped so that the lower part of the collector 9 is narrowed, and a wire brush 9 a is provided at the lower end of the collector 9. The attached viscous oil is scraped off with the wire brush 9a.

  Moreover, since the wire brush 9a is in contact with the wire 5, the wire brush 9a can be replaced. In order to reduce wear caused by the contact with the wire-5, the root portion of the wire brush 9a is not shown, but fluorine-containing rubber is not shown. Alternatively, it is fixed with a fluorine-containing resin.

  As a result, the wire brush 9a has elasticity, and the wear can be alleviated by contact.

  Further, a sheathed heater 17 is provided on the fixed plate 2 to which the collector 9 is fixed, and the collector 9 is heated to 40 ° C. to 50 ° C. by heat conduction from the fixed plate 2. This temperature adjustment can be controlled by providing a thermistor (not shown) on the fixed plate 2 in the vicinity of the collector 9.

  A guide 10 fixed to the fixed plate 2 that receives the falling viscous oil separated by the collector 9 and guides it to the guide cylinder 11 is provided below the collector 9. The viscous oil is recovered from the guide tube 11 to the recovery container 12.

  The underground soil 13 and the permeable layer 14 through which the groundwater flows are excavated in the lower part of the housing 1, and the tubular body (B) 15 is inserted into the excavation hole to form a passage 16.

  The bottom of the cylindrical body (B) 15 located in the water permeable layer 14 is formed with a large number of holes and slits (not shown) so that groundwater and viscous oil can sufficiently enter and pass through.

  The passage 8 and the passage 16 inside the tubular body (B) 15 are installed inside the tubular body 7 so as to be coaxial.

  Next, the basic operation in this embodiment will be described.

  The geared motor 4 which is a driving means is driven to rotate the rotating body 3, and the wire 5 which is the collecting body 9 wound around the winding portion 3 a of the rotating body 3 is connected to the passage 8 and the passage 16 with the weight 6. The lower end is suspended in the vertical direction so as to reach the permeable layer 14 through which groundwater flows.

  At this time, the wire 5 is positioned substantially at the center of the passage 8 and the passage 16 with reference to the collector 9 as oil separation means.

  The inner diameters of the passage 8 and the passage 16 may be about 50 millimeters, for example.

  The position where the weight 6 reaches the lower part of the permeable layer 14 through which the groundwater flows is stored in the control means 4a and set as installation conditions.

  Next, the rotating body 3 is rotated to wind the wire 5 around the winding unit 3a and move it upward.

  At this time, the wire 5 sequentially contacts the viscous oil floating on the liquid surface of the water permeable layer 14, and the viscous oil adheres to the surface of the wire 5.

  Further, when the lower end of the wire 5 to which the viscous oil is attached passes through the collector 9 which is an oil separating means for separating the viscous oil, the rotating direction of the rotating body 3 is controlled to be reversed, the wire 5 is moved downward, and the weight At the position where 6 reaches the lower part of the water permeable layer 10, the rotating direction of the rotating body 3 is reversed again to move the wire 5 upward, and the wire 5, which is a capturing body having a certain length, is moved in the vertical direction at a certain cycle. To move up and down.

  By this operation, the viscous oil adhering to the wire 5 is separated from the wire 5 by the wire brush 9a of the collector 9 as a separating means and falls.

  This is received by the inclined guide 10 and flows to the guide body 11, and the viscous oil is recovered in the recovery container 12.

  Thus, the wire 5 which is a capturing body having a certain length is moved up and down in the vertical direction, and when the wire 5 descends, liquid viscous oil is attached to the wire 5, and the wire 5 is a liquid surface which is groundwater. When it rises upward, the adhering floating viscous oil is separated and collected by the collector 9 as the separating means.

  In the prior art, an endless belt to which viscous oil is attached is supported by a plurality of rollers and is driven to rotate.

  Therefore, the structure is complicated and large, and the cost is high.

  Further, there are problems in that the circulating travel produces a large noise, the durability of the belt, and the required driving power increase.

  On the other hand, in the embodiment of the present invention, the wire 5 that is the capturing body is moved up and down in the vertical direction, so that the configuration of the recovery device can be simplified and the viscous oil can be recovered efficiently, and the noise can be reduced. Durability can be improved.

  Further, by winding the wire 5 as a capturing body around the rotating body 3 and controlling the geared motor 4 as the driving means of the rotating body 3 to forward and reverse rotation, the wire 5 can be moved up and down with simple means with high accuracy. Can be moved.

  Furthermore, the period of the vertical movement of the wire 5 can be adjusted by changing the rotation speed of the rotating body 3.

  Furthermore, the distance between the liquid surface on which the viscous oil floats and the separating means for separating and separating the viscous oil vary depending on the situation. Conventionally, in order to cope with this, the vertical distance by belt replacement or mechanical means However, maintenance is necessary each time, and the adjustment range of the vertical distance is not large.

  On the other hand, according to the present embodiment, the moving distance by which the wire 5 that is the capturing body is moved up and down by controlling the rotation direction or the rotation angle of the rotation means of the rotation body and switching the rotation direction of the rotation body or the reverse rotation. Can be set easily.

  Thereby, it is possible to easily cope with the distance difference from the ground to the water permeable layer 14, that is, the difference in the distance between the liquid surface where the viscous oil floats and the collector 9 which is a separating means for separating and separating the viscous oil. it can.

  Further, the passage 8 and the passage 16 are formed by excavating from the ground so as to reach the permeable layer 14, and the wire 5 which is a capturing body is moved up and down in the passage 8 and the passage 16 so that the viscous oil of the groundwater is supplied. By collecting, it is possible to simplify the collecting device, reduce noise and improve durability.

  In particular, the noise is remarkably reduced, the large driving power of the rotating body 3 is not required, and the durability is excellent, so that noise pollution is not caused even during day and night operation, and energy saving can be achieved. .

  Moreover, it is necessary to always insert an endless belt into the conventional liquid and to provide a rotating roller at the lower end of the endless belt.

  Accordingly, it is necessary to increase the size of the passage in order to insert the rotating roller and prevent contact with others.

  Therefore, there is a problem that requires great power, equipment, and labor for underground excavation.

  On the other hand, according to this embodiment, it is not necessary to provide a rotation roller in the lower end part of the wire 5 which is a capturing body.

  As a result, the diameter of the passage 16 can be reduced, and the work can be easily performed without requiring large power and equipment for excavation in the ground.

  The present invention can also be applied to the field of collecting adhesive substances that are separated and suspended on a liquid.
