DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The utility model provides a technical solution: comprising a sewage treatment component 1, a preliminary filtering component 2 is fixedly installed at one end of the sewage treatment component 1, and a collecting component 3 is fixedly connected to the bottom of the preliminary filtering component 2;

The sewage treatment assembly 1 comprises a sewage treatment equipment body 101, a connection port 102 is provided in the middle of one end of the sewage treatment equipment body 101, and a drain port 103 is fixedly installed at the bottom of the back of the filter cartridge 201;

The preliminary filtering assembly 2 comprises a filter cartridge 201 and a water inlet 202, wherein the water inlet 202 is arranged on the top of the front of the filter cartridge 201, an outer circular plate 203 is fixedly installed in the front of the filter cartridge 201, an inner circular plate 204 is rotatably installed in the front of the outer circular plate 203, a water through port 205 is provided on the surface of each of the outer circular plate 203 and the inner circular plate 204, a filter plate 206 is fixedly installed in the rear of the filter cartridge 201, a rotating motor 207 is fixedly installed at the center of the front of the filter cartridge 201, the output shaft of the rotating motor 207 extends to the inside of the filter cartridge 201 and is fixedly installed with a circular shaft, one end of the circular shaft passes through the inner circular plate 204 and the outer circular plate 203 and extends to the front of the filter plate 206, a sweeping plate 208 is fixedly installed on one end of the circular shaft close to the filter plate 206, and a sewage outlet 209 is provided at the bottom of the filter cartridge 201;

The collecting assembly 3 includes a collecting shell 301, a circular tube 302 is arranged on the top surface of the collecting shell 301, a mesh frame 304 is arranged inside the collecting shell 301, a slot is provided on the front of the top surface of the collecting shell 301, a partition 305 is movably inserted in the slot, a fixing plate 306 is fixedly installed on one side of the top surface of the collecting shell 301, a threaded rod 307 is rotatably installed on one side of the fixing plate 306, a sliding sealing plate 308 is slidably installed on the top surface of the collecting shell 301 and on one side of the circular tube 302, and the sliding sealing plate 308 is threadedly sleeved on the threaded rod 307.

In this embodiment, the back end of the filter cartridge 201 is fixedly connected to the connection port 102 , and the top end of the circular tube 302 is fixedly connected to the sewage outlet 209 .

Meanwhile, the top surface of the mesh frame 304 is provided with a plurality of through holes, and the top surface of the mesh frame 304 is provided with a circular opening corresponding to the circular tube 302 , through which impurities can be conveniently dropped into the mesh frame 304 .

The back side of the partition 305 is in contact with the front side of the mesh frame 304, and the sliding sealing plate 308 is slidably inserted into the circular tube 302 from one side of the circular tube 302. The sliding sealing plate 308 moves to one side to make the circular tube 302 and the mesh frame 304 communicate with each other, so that the filtered impurities can fall into the mesh frame 304.

The inner circular plate 204 is fixedly sleeved on the circular shaft, and the back side of the sweeping plate 208 fits with the front side of the filter plate 206. In order to avoid excessive accumulation of impurities that may clog the mesh of the filter plate 206, the sweeping plate 208 can be driven to rotate by the rotating motor 207 to cause the impurities stuck on the filter plate 206 to fall off and fall into the filter cylinder 201 or the circular tube 302.

A sliding ladder 303 is fixedly installed on the inner walls of both sides of the collecting shell 301, and the screen frame 304 is slidably installed on the sliding ladder 303, so that the screen frame 304 can be easily installed and pulled out.

During use, sewage enters the filter cartridge 201 from the water inlet 202. When the sewage flow is too large, in order to avoid excessive operating load on the filter plate 206 and the sewage treatment equipment body 101, the rotating motor 207 can be started to drive the inner circular plate 204 to rotate on the surface of the outer circular plate 203. The rotation of the inner circular plate 204 can make the water through holes 205 opened on its surface overlap with the water through holes 205 opened on the surface of the outer circular plate 203 periodically, so that the sewage can periodically pass through the two water through holes 205, thereby playing a flow limiting role, which can effectively avoid the situation where the device is overloaded due to the large sewage flow. At the same time, the sludge and other solid impurities in the sewage can be filtered through the filter plate 206, and the solid impurities in the sewage can be initially intercepted by the filter plate 206, and the intercepted impurities will enter the circular tube 302. At the same time, in order to avoid excessive accumulation of impurities and cause the filter plate 2 06 mesh is clogged, so the sweeping plate 208 can be driven to rotate by rotating the motor 207 to make the impurities stuck on the filter plate 206 fall off and fall into the filter cartridge 201 or the circular tube 302. After filtering for a period of time, the user only needs to rotate the threaded rod 307 regularly. The rotation of the threaded rod 307 can drive the sliding sealing plate 308 threadedly sleeved thereon to move to one side so that the circular tube 302 and the mesh frame 304 can communicate with each other, so that the filtered impurities can fall into the mesh frame 304. After the intercepted impurities are emptied, the threaded rod 307 is rotated in the opposite direction to reinsert the sliding sealing plate 308 into the circular tube 302. Whether the impurities in the mesh frame 304 need to be cleaned up can be observed by pulling out the partition 305. If the number is too large, it is only necessary to pull out the mesh frame 304 and lift the filter net on the top, and then pour the impurities out to the recycling place.

To sum up, the buried rural decentralized sewage treatment device controls the rotation of the inner circular plate. The rotation of the inner circular plate can make the water inlets opened on its surface overlap periodically with the water inlets opened on the surface of the outer circular plate 203, so that the sewage can pass through the two water inlets periodically, thereby playing a flow limiting role, avoiding the situation where the device is overloaded due to the large sewage flow. At the same time, the sludge and other solid impurities in the sewage are preliminarily filtered and intercepted by the filter plate, and the intercepted impurities will enter the circular tube. At the same time, in order to avoid the clogging of the mesh of the filter plate caused by excessive accumulation of impurities, the sweeping plate can be controlled to rotate to make the impurities stuck on the filter plate fall off and fall into the filter barrel or the circular tube. After filtering for a period of time, the user can control the sliding sealing plate to move to one side to make the circular tube and the mesh frame communicate with each other, so that the filtered impurities can fall into the mesh frame for subsequent centralized treatment. There is no need for users to frequently open the various components of the device for cleaning, which is more practical.
