Description

A stool receiving tank

technical field

The utility model relates to a feces receiving tank, which is specifically used for receiving and pretreating feces.

Background technique

Feces enter the municipal pipe network and mix with domestic sewage and then enter the sewage treatment plant for treatment. This is a treatment method commonly used in developed countries. Many newly built cities and urban areas in my country also adopt this mode. The sewage pipes using this mode are usually designed Larger, no septic tank is required, and no special treatment of feces is required. However, there are still many old urban areas in my country that do not have a sewage pipe network, or the sewage pipe network is relatively backward, and the feces cannot be discharged directly into the sewage pipe network. It is necessary to set up a septic tank and clean it regularly. Sent to the feces treatment plant for harmless treatment. After the fecal suction truck enters the feces treatment plant, it needs to receive the feces. There are still many plastic pieces, styrofoam, hair, sand and gravel in the feces, which need to be removed. The current feces treatment plants usually use a complete set of equipment for solid-liquid separation of slag removal. The feces suction truck is connected to the complete set of equipment for solid-liquid separation of slag removal through pipelines, and the feces are discharged into the equipment through the pipeline. The treated liquid enters the adjustment tank and is reused Pumping to the next processing step. There is a disadvantage of using this method, that is, when the feces are thicker and there are more debris, the pipeline is easy to block, and a feces receiving tank is often added, and the feces are unloaded into the tank to dilute and then pumped into the slag removal solid-liquid separation set Equipment cleaning.

Utility model content

The technical problem to be solved by the utility model is to provide a feces receiving tank for the above-mentioned deficiencies in the prior art, which can not only receive feces conveniently, but also remove sundries, and can also avoid the adjustment tank in the existing process.

The technical solution adopted by the utility model to solve the technical problem is: a feces receiving tank, including a tank body, a grid, a screw conveyor for grid slag, a screw conveyor for heavy debris at the bottom, and a screw conveyor for dumping heavy debris. The body is a rectangular bucket bottom steel trough, the trough is divided into three layers, the upper layer is the receiving and debris filtering area, the middle layer is the feces storage area, and the lower layer is the heavy debris collection area; the upper layer receiving and debris filtering area includes a row Inclined grid and screening screw conveyor; grid dumping is installed at the bottom of the material receiving and sundry filtering area; screening screw conveyor is installed at the lower end of the grid, installed horizontally, and sends screenings out of the tank, and screenings The tank body at the lower part of the screw conveyor has a leak hole, and the feces slurry leaks down to the feces storage area in the middle layer through the leak hole;

The middle-level feces storage area of the tank body is provided with a feces slurry discharge pipe;

The lower heavy debris collection area of the tank is a triangular bucket, which is composed of two inclined steel plates and two side wall steel plates. The heavy debris screw conveyor is installed in the long direction of the bottom of the bucket. A discharge port is arranged at the end of the forward direction of the sundry screw conveyor, and the discharge port is connected to a screw conveyor for dumping heavy sundries arranged obliquely.

Further, the grid gap size of the grid is 10-20 mm.

Further, a pump is connected to the excrement slurry discharge pipe.

Further, a glove box is provided at the end of the screw conveyor for dumping heavy sundries in the forward direction.

A stool receiving tank described in the utility model has the following advantages:

The feces receiving tank of the utility model can allow the feces suction truck to directly unload the feces into the receiving material and debris filtering area of the feces receiving tank. The grid is installed obliquely, and the sundries are intercepted and then sent to the screen slag screw conveyor installed at the bottom of the grid to be conveyed out of the tank. The casing at the lower part of the screen slag screw conveyor has a liquid leakage hole, and the feces slurry will leak through the liquid leakage hole without being sent out of the tank by the screw conveyor. The feces slurry entering the tank is temporarily stored in the tank, and the heavy debris such as sand and gravel in the slurry will sink to the bottom of the bucket-shaped tank, and the debris will slide down along the inclined bucket wall at the bottom of the tank and enter the screw at the bottom of the bucket. The conveyor is sent out of the trough, and then lifted by the dumping screw conveyor into the glove box for removal.

The utility model enables the feces to be directly unloaded into the tank without being connected by pipes, and the pipes will not be blocked; the utility model can intercept the coarse debris in the feces by setting the grille, and can transport the debris out through the screw conveyor Tank body; the bottom of the tank body of the utility model is bucket-shaped, and the precipitated heavy sundries can be transported out of the tank body by a screw conveyor.

Detailed ways

Describe the specific implementation of the utility model below in conjunction with accompanying drawing and embodiment:

Figures 1 to 3 show the specific implementation of the utility model. As shown in the figure, the feces receiving tank of the utility model is mainly composed of a tank body 1, a grid 3, a grid slag screw conveyor 4, and a screw conveyor for heavy debris at the bottom. Machine 8 and screw conveyor 9 for dumping heavy debris. The tank body is a rectangular bucket-bottom steel tank. The tank body is divided into three layers. Debris collection area 7. The material receiving and debris filtering area on the upper layer is composed of a row of inclined grids and screening screw conveyors. The grids are dumped and installed at the bottom of the material receiving area. 20mm, the screen slag screw conveyor is installed at the lower end of the grille, installed horizontally, and can send the screen slag out of the tank. The shell at the lower part of the screw conveyor has a leak hole, and the feces slurry can leak down without being sent out by the screw conveyor Tank body. The middle layer of the tank is the feces storage area, which can temporarily store the feces filtered by the grille. The heavy debris such as sand and small stones in the feces will sink into the heavy debris collection area. The middle layer of the tank body is equipped with feces slurry discharge The pipe can be connected to a pump to pump the feces to the next treatment process. The lower layer of the trough is a triangular bucket, which is the heavy debris collection area. It is composed of two inclined steel plates and two side wall steel plates. The bottom of the bucket is equipped with a heavy debris screw conveyor in the long direction. Stones and other heavy debris settle into the screw conveyor and are sent out of the tank.
