[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to an apparatus for removing fibrous substances contained in sewage, and in particular, fibrous hardly decomposable substances such as hair contained in sewage flowing into a small-scale sewage treatment plant (in this specification, “fiber”). The present invention relates to an apparatus for removing fibrous substances contained in sewage, which can capture and remove the substance by simple means, and can keep the height of the machine low.
[0002]
[Prior art]
Conventionally, sewage that flows into a sewage treatment plant includes not only bulk degradable substances such as human excrement and cocoons, but also bulk refractory substances such as plastic lumps, pieces of wood and empty cans, and fiber such as hair. In particular, in a small-scale sewage treatment plant, only a simple dust removing means for removing massive, hardly decomposable substances among substances contained in sewage has been installed.
[0003]
[Problems to be solved by the invention]
As this dust removing means, it captures and removes bulky hardly decomposable substances among the substances contained in the wastewater flowing into the sewage treatment plant, pulverizes the bulky degradable substances, and introduces them into the treatment tank together with the wastewater. However, depending on the dust removing means, it is not possible to capture and remove fibrous persistent materials such as hair, and these fibrous persistent materials cannot be removed. There is a problem that the wastewater treatment is hindered by being entangled with a sensor, a pump, or the like in a treatment tank or the like installed in a treatment tank or the like, causing a malfunction of the sensor or a reduction in the treatment capacity of the pump.
[0004]
In order to cope with this problem, it is conceivable to use a very fine screen, for example, a screen having a mesh width of about 2 mm, as a screen of the dust removing means. Since a large amount of the degradable substance is trapped and the trapped residue is rotted inside the dust removing means, it is difficult to treat the trapped residue in a sanitary manner. Even when using, the fibrous persistent material could not be completely removed.
[0005]
In view of the problems of the above-described conventional sewage treatment plant, the present invention efficiently captures fibrous persistent materials such as hair contained in sewage by a device having a low mechanical height and a simple mechanism. An object of the present invention is to provide an apparatus for removing fibrous substances contained in sewage that can be removed and stably treated with sewage.
[0006]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the apparatus for removing fibrous substances contained in sewage according to the present invention comprises a wire unwinding drum and a winding drum installed above a water tank through which sewage circulates, and an unwinding drum. It is characterized by comprising a corner guide that immerses and stretches the rope stretched over the winding drum at a predetermined depth in the water tank, and a suspension support means that suspends the corner guide so that it can be raised and lowered.
[0007]
The apparatus for removing the fibrous substance contained in the sewage is immersed and stretched in the water tank on the take-up drum through a corner guide immersed in the sewage from the unwinding drum installed above the water tank in which the sewage circulates. The fibrous material contained in the sewage circulating in the water tank is hooked on the rope that has been stretched in this manner, and the rope is wound around the winding drum while being unwound from the winding drum intermittently or continuously. As a result, the fibrous material caught on the rope is pulled up onto the water surface together with the rope and removed from the wound sewage.
Further, during maintenance and the like, the corner guide can be pulled up onto the water surface by the hanging support means, so that the machine height does not increase and a compact device configuration can be obtained.
[0008]
In this case, the suspension support means is composed of a winch and a tube member having a telescopic rigidity that covers the outer periphery of the suspension rope led out from the winch and connects the suspension support means and the fixed side. be able to.
[0009]
As a result, it is possible to prevent the fibrous material contained in the sewage circulating in the water tank from being caught by the suspension rope led out from the winch, and the corner guide is formed by the water flow of the sewage circulating in the water tank. It can be prevented from moving, and the rope can be stably immersed and stretched at a predetermined position in the water tank.

Can be reused if necessary after incineration treatment with the fibrous material such as hair removed from the waste water on the cord 3 wound on the winding drum 22, while synthetic resin yarn or the like When the flammable wire rod is used, the cord 3 wound around the winding drum 22 can be incinerated together with fibrous substances such as hair removed from the sewage.
[0018]
In addition, the strip 3 is spaced at a predetermined interval so that the fibrous material caught on the strip 3 can be pulled out onto the water surface by feeding the strip 3 while preventing the fibrous material from being detached. Thus, a large number of nodes 31 are formed.
The node 31 can be formed by, for example, connecting the rope 3, or can be constituted by a protrusion protruding from the rope 3.
[0019]
In this embodiment, the corner guide 23 is composed of a sheave 23S. In addition, the corner guide 23 is a second example of the apparatus for removing fibrous substances contained in sewage according to the present invention shown in FIGS. As in the second to fourth embodiments, the pipe 23P bent in a semicircular arc shape can be used.
The corner guide 23 made of the sheave 23S or the pipe 23P has a weight that does not float due to the tension applied to the rope 3 when the rope 3 is unwound from the unwinding drum 21 and wound around the winding drum 22. Set to.
[0020]
