  Furthermore, according to the invention described in claim 3, the vacuum pump is characterized in that the engine or the engine mounted on the automobile on which the drum can is loaded is a power source or an electric pump. It has an excellent effect that the size of vacuum force can be selected.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic view of the apparatus of the present application, and FIG. 2 is a cross-sectional view of a drum can with an open top lid.

  In the figure, reference numeral 1 denotes a drum can. The drum can 1 includes a closed type and an open type. Most of the former are made of iron plate, originally filled with gasoline, chemicals and other fluids or semi-fluids, and are strong with corrugated irregularities on the barrel, so the external drum can be scratched. After repairing, cleaning and drying the inside, it was checked that there were no holes (leak test) and was used for reuse. In the latter case, the upper lid and the main body body are separately prepared, and are used in an airtight and liquidtight manner by a fastening means.

  The upper lid of the closed-type drum can originally has an air port for venting air and an inlet (a double outlet) for contents. Moreover, the open type drum can is not limited to an iron plate, and an air port, an inflow port, and other facilities can be freely formed. In this specification, in particular, any drum can be referred to other than the open type drum.

  A vacuum pump (exhaust blower) 5 is connected to an air port 3 provided in the upper lid (top plate) 2 of the drum can 1 via an air hose 4. A base end 7 ′ of a carry-in hose 7 is connected to an inlet (cum outlet) 6 provided in the upper lid 2, and a tip 7 ″ of the carry-in hose 7 is, for example, as shown in FIG. The material to be sucked (for example, sludge) 9 stored in

  Thus, when the vacuum pump 5 is operated and the inside of the drum can 1 is evacuated (reduced pressure), the suction target 9 stored in the underground storage 8 can be pumped through the carry-in hose 7 by the vacuum force. The capacity of the sucked object 9 that has flowed into the drum 1 is checked by a sensor 10 to stop the operation (suction) of the vacuum pump 5. The sensor 10 has a float type (floating when the object to be sucked is in a liquid state and outputs a signal) and a capacitance type (plus the detection part of the rod and minus the object to be sucked). And detecting a capacity by electrostatic force and outputting a signal).

  The former float type sensor 10 is installed in a state in which the airtight liquid tightness of the carry-in hose 7 connected to the inlet 6 of the drum can 1 is not obstructed when the drum can 1 is a closed type that cannot process additional equipment. (See FIG. 1). In addition, the capacitance type sensor 10 can be installed in an airtight and liquid-tight manner at an appropriate position (substantially in the center) of the upper lid 2 of the open type drum can 1 capable of processing additional equipment (see FIG. 2).

  The vacuum pump 5 is a device (exhaust blower) used for sucking out a gas under atmospheric pressure and raising the degree of vacuum. The pressure display below the atmospheric pressure includes an atmospheric pressure reference (gauge pressure) expressed by a difference from the atmospheric pressure as a reference, and an absolute pressure reference (absolute pressure), and the former display is expressed as negative. Thus, the atmospheric pressure standard for closed type drums is said to be around 3 mH2 O (water column), but it has been experimentally confirmed that the atmospheric pressure standard for open type drums is 6 mH2 O (water column) or more. ing.

  The vacuum pump 5 can be roughly classified into several types according to the principle and structure, but in the present embodiment, a mechanical vacuum pump is used. Among mechanical vacuum pumps, the main part is in the casing by the action of a cylinder, piston and a pump consisting of a suction valve, a discharge valve provided on the cylinder end or side, or two rotors rotating in opposite directions in the casing. A rotary blower of a type that transfers the trapped gas from the suction side to the discharge side of the casing may be used.

  The operation of the piston or the rotor may use an engine as a power source, or an engine mounted on an automobile on which a drum can be loaded. Furthermore, when the object to be sucked is a small amount, an electric motor that operates with an electric lamp line (100 V) is used as a drive source. The vacuum pump (blower) 5 is started manually, but stopped automatically by the sensor 11. However, it is possible to enable start and stop by operating the hand switch (controller). The vacuum pump (blower) 5 can be operated by switching its suction side and discharge side.

  The connecting means of the air hose 4 for connecting the air port 3 of the drum 1 and the vacuum pump 5 and the connecting means of the inlet 6 of the upper lid 2 of the drum 1 and the base end 7 'of the carry-in hose 7 are shown in the figure. However, it is preferable that the male and female coupling (pipe joint) can be made by a one-touch method adopted in a fire engine or the like. The carrying hose 7 has a standard length from the base end 7 ′ to the tip 7 ″, but depending on the distance between the drum 1 and the storage 8, it is attached to both ends. A joint hose (not shown) may be prepared, and if the carry-in hose 7 and the joint hose are formed of a transparent material, the color of the suction object passing through the hose and the flow state Is preferable because it is visible.

  When the drum 1 is of an open type in which the upper lid 2 and the main body body 1 ′ are separately formed as shown in FIG. 2, the air lid 3 and the inlet (cum outlet) 6 are provided in the upper lid 2. In addition, a hose connection terminal 11 and a hose connection terminal 11 ′ are provided near the bottom of the main body body 1 ′. Thus, when the open type drum cans 1 are connected in series, the hose connection terminals 11 of the upper lid 2 of one drum can 1 (A) and the next drum can 1 (B) are connected by the connecting hose 12. (Solid line), a hose connection terminal 11 ′ near the bottom of the main body body 1 ′ of one drum can 1 (A), and an inlet (cum outlet) 6 of the upper lid 2 of the next drum can 1 (B) May be connected by a connecting hose 12 '(one-dot chain line). These are for connecting a number of open-type drums to increase the collection capacity of sludge and the like. However, when the hose connection terminals 12 of the upper lid 2 are connected to each other, the sludge pumped into the drum can be settled and separated sequentially, which is effective.

  As described above, even when several drum cans 1 are connected in parallel or in series, the air ports 3 provided in the upper lid 2 of each drum can 1 are connected to the vacuum pump 5 via the air hoses 4, respectively. . In this case, it is needless to say that the sensor 10 is installed in the final drum 1 as shown in FIG.

  The vacuum pumping device of the present application shown in the above embodiment includes the number of empty drums 1, vacuum pumps 5, and various hoses (air hose 4, carry-in hose 7, splice hose, connecting hose 12, etc.) necessary for the truck bed. ) And head to the site (for example, a factory where sludge is stored in an underground storage).

  Therefore, a vacuum pump 5 is connected to an air port 3 provided on the upper lid 2 of the drum can 1 via an air hose 4, and a distal end of a carry-in hose 7 having a base end 7 ′ connected to an inlet 6 provided on the upper lid 2. 7 ″ is put into the sludge (subject to be sucked 9) stored in the underground storage 8 and the vacuum pump 5 is operated.

  After that, the vacuum pump 5 is operated to draw out the air from the drum can 1 at the site, and the vacuum force causes the sludge in the underground storage 8 to be pumped into the drum can 1. In collecting this sludge, the air in the drum can 1 at the site is exhausted to the atmosphere one after another by the action of the vacuum pump 5, so even if the sludge is pumped up by gas-liquid mixing, the air component does not accumulate. Therefore, the net sludge can be collected efficiently. This net sludge amount is charged to the client as a collection fee.

  Thus, when all of the sludge has been collected sequentially, take it back to the base, and depending on the type of sludge in the drum 1, if the drum is open, open the top lid 2 and lift it into the treatment facility with a crane. In the case of a closed type, the suction side and the discharge side of the vacuum pump 5 are switched and discharged. In addition, the supernatant portion and the settled portion may be distinguished by a predetermined process (for example, sedimentation separation) and sold to a recycling company.

  Further, the vacuum pumping device of the present embodiment shown in the above embodiment, for example, fills the drum 1 loaded on the truck bed with water pumped up from a river or a well, and switches between the suction side and the discharge side of the vacuum pump 5. It will be easy to water the crops on dry and dry farms.

  Furthermore, it is of course possible that the vacuum pumping device of the present application shown in the above embodiment can be used as a water supply vehicle at the time of disaster or drought by filling the drum can on the truck bed with drinking water.

  The present invention can collect aspirated material pumped up by the vacuum force generated by the reduced pressure of the drum, particularly sludge collected in a specific place, sludge collected in a pond created in a golf course or a private garden, etc. . That is, it is suitable for use in various types of waste liquid treatment including industrial processes, and its environmental applicability is extremely large.

It is the schematic of this application apparatus. It is sectional drawing of the drum can which made the upper cover an open type.
