[0039] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0040] like Figures 1-13 An industrial wastewater treatment tank and wastewater treatment method are shown, including a tank body 1 and a controller. A connecting box 2 is provided on one side of the tank body 1. A filter screen is fixedly connected to the inner wall of the connecting box 2. A return pipe 201 connected to the tank body 1 is provided on the surface of the connecting box 2. A water injection pipe is connected to one side of the tank body 1, and a water outlet pipe is connected to the other side of the tank body 1. A motor 32 is provided on one side of the top of the tank body 1. A threaded rod 3 is fixedly connected to the output shaft of the motor 32. Guide rods 31 symmetrically distributed with the threaded rod 3 are fixedly connected to the top of the tank body 1. A cleaning module 4 is provided inside the tank body 1. An outlet 101 located above the connecting box 2 is opened on the surface of the tank body 1.

[0041] The cleaning module 4 includes a scraping structure for cleaning dirt from the inner wall of the pool 1, and the surface of the scraping structure is provided with an auxiliary structure 41 for discharging dirt.

[0042] The scraping structure comprises a connecting frame 401 arranged in the pool body 1, the cross-sectional shape of the connecting frame 401 is U-shaped, one side of the connecting frame 401 is fixedly connected with a scraper plate 402, the outer side of the scraper plate 402 is in contact with the inner wall of the pool body 1, and the surface of the scraper plate 402 is provided with uniformly distributed through grooves 403.

[0043] Both ends of the connecting frame 401 are fixedly connected with sliding blocks 404, the upper ends of the two sliding blocks 404 penetrate out of the pool body 1, one of the sliding blocks 404 is threadedly connected with the surface of the threaded rod 3, and the other sliding block 404 is slidably connected with the surface of the guide rod 31.

[0044] The threaded rod 3 can be rotated under the rotation of the output shaft of the motor 32, so that the sliding block 404 threadedly connected with the threaded rod 3 moves along the threaded rod 3, and in this process, the other sliding block 404 and the guide rod 31 are arranged to cooperate with the connecting frame 401 to ensure that the sliding block 404 does not rotate with the threaded rod 3, and the movement direction of the sliding block 404 can be changed by controlling the forward and reverse rotation of the output shaft of the motor 32.

[0045] As shown in Figures 1-13 The inner side of the connecting frame 401 is slidably connected with a sliding plate 418, one side of the sliding plate 418 is fixedly connected with a return spring 417, the inner wall of the connecting frame 401 is provided with a pressure sensor 419, the surface of the pressure sensor 419 is provided with a buffer block, one end of the return spring 417 is fixedly connected with the surface of the buffer block, the outer side of the connecting frame 401 is provided with uniformly distributed stop blocks 410 corresponding to the through grooves 403, the cross-sectional shape of the stop blocks 410 is a right trapezoid, the inner part of the connecting frame 401 is provided with uniformly distributed adjusting cavities 413 corresponding to the stop blocks 410, the sliding plate 412 is slidably connected with the inner wall of the adjusting cavity 413, the surface of the sliding plate 412 is fixedly connected with a sliding rod 414, one end of the sliding rod 414 penetrates out of the connecting frame 401 and is fixedly connected with the surface of the adjacent stop block 410, and the second spring 415 is fixedly connected between the sliding plate 412 and the inner wall of the adjusting cavity 413.

[0046] The inner part of the connecting frame 401 is provided with a liquid storage cavity 405, the inner part of the liquid storage cavity 405 is provided with an adjusting rod 406, one end of the adjusting rod 406 penetrates out of the connecting frame 401, the other end of the adjusting rod 406 penetrates the connecting frame 401 and the scraper plate 402 in sequence, the surface of the adjusting rod 406 is fixedly connected with an extrusion plate 416 slidably connected with the inner wall of the liquid storage cavity 405, one side of the extrusion plate 416 forms a storage cavity with the inner wall of the liquid storage cavity 405, the inner part of the storage cavity is filled with hydraulic oil, and the inner part of the connecting frame 401 is provided with a connecting channel 411 for communicating the adjusting cavities 413, and one end of the connecting channel 411 is in communication with the storage cavity.

[0047] The inner top wall of the liquid storage cavity 405 is provided with a receiving cavity. A limiting rod 408 is slidably connected inside the receiving cavity. A first spring 407 is fixedly connected between the upper end of the limiting rod 408 and the inner wall of the receiving cavity. Two limiting grooves 409 are provided on the surface of the adjusting rod 406. The lower end of the limiting rod 408 passes through the receiving cavity and extends into the interior of the limiting groove 409. The lower end of the limiting rod 408 is hemispherical.

[0048] As the connecting bracket 401 moves toward the motor 32, the position of the stop block 410 is as follows: Figure 3 As shown, the scraper 402 scrapes the dirt from the inner wall of the tank 1 along the moving direction, reducing the adhesion of dirt to the inner wall of the tank 1 and affecting the sewage treatment effect. At the same time, due to the setting of the through groove 403, the scraped dirt is pushed by the water flow during the movement of the scraper 402 and guided to the other side of the scraper 402 through the through groove 403, preventing the pushed dirt from sticking to the other inner wall of the tank 1. Until the scraper 402 is in close contact with the inner wall of the tank 1, the obstruction of the inner wall of the tank 1 pushes the adjusting rod 406 and the squeezing plate 416 to move synchronously, so that the squeezing plate 416 squeezes the hydraulic oil stored in the storage cavity. The squeezed hydraulic oil is injected into the interior of the adjusting cavity 413 through the connecting channel 411, thereby pushing the slide plate 412 to slide along the inner wall of the adjusting cavity 413 and driving the slide rod 414 to stop the block 4. 10. Simultaneously, the blocking channel 403 is moved to compress the second spring 415, and the output shaft of the motor 32 is reversed to make the connecting frame 401 move in the opposite direction. During this process, the stop block 410 can scrape the area that cannot be cleaned at the original opening of the channel 403. After moving to the inner wall on the other side and the sliding plate 418 contacts the inner wall, pressure is applied to the pressure sensor 419. After the pressure sensor 419 detects that the pressure exceeds the preset value, it transmits a signal to the controller to stop the output of the motor 32. At this time, under the combined action of the connecting frame 401, scraper 402, stop block 410, sliding plate 418 and pool 1, dirt can be stored in the gap between the connecting frame 401 and scraper 402, and this gap can be connected to the discharge port 101, which is convenient for subsequent cleaning by the auxiliary structure 41.

[0049] After 15 minutes of cleaning, the motor 32 drives the connecting frame 401 to continue moving until the connecting frame 401 is in close contact with the inner wall of the pool body 1. Then the output shaft of the motor 32 rotates in the forward direction, thereby driving the connecting frame 401 to reset and clean again. Under the obstruction of the inner wall on the other side of the pool body 1, the adjusting rod 406 and the squeezing plate 416 are pushed to reset. At this time, due to the increased space in the storage cavity of the reset squeezing plate 416, the sliding plate 412 can be driven to reset under the action of the second spring 415 and the hydraulic oil can be squeezed back into the storage cavity, so that the stop block 410 no longer blocks the through groove 403.

[0050] The limiting groove 409 and the limiting rod 408 are arranged to limit the position of the adjusting rod 406 after the adjusting rod 406 is adjusted by the inner walls on both sides of the pool body 1, and the lower end of the limiting rod 408 is tightly attached to the inner wall of the limiting groove 409 under the action of the first spring 407, so that the position of the adjusting rod 406 is prevented from being deviated during movement. The lower end of the limiting rod 408 is arranged in a semispherical shape, which can be easily pressed by the inner wall of the pool body 1 to be lifted up, thereby facilitating the adjustment of the position of the adjusting rod 406.

[0051] As shown in Figures 1-10 The auxiliary structure 41 includes three rotating blocks 4102 arranged at the bottom of the connecting frame 401. The top of each rotating block 4102 is fixedly connected with a connecting shaft, the upper end of the connecting shaft penetrates into the interior of the connecting frame 401 and is rotationally connected with the inner wall of the connecting frame 401. The interior of each rotating block 4102 is provided with a connecting cavity 4105, and the bottom of each rotating block 4102 is provided with cleaning rods 4104 which are uniformly distributed and communicate with the connecting cavity 4105. The surface of each cleaning rod 4104 is provided with uniformly distributed discharge holes 4112.

[0052] The interior of the connecting frame 401 is provided with three flow guide cavities 4113 which are coaxially arranged with the three rotating blocks 4102, respectively. The interior of the connecting frame 401 is provided with flow channels 4114 which are used to communicate two adjacent flow guide cavities 4113. The top of each rotating block 4102 is eccentrically communicated with a connecting pipe 4103, and the upper end of the connecting pipe 4103 penetrates through the connecting frame 401 and communicates with the flow guide cavity 4113.

[0053] The auxiliary structure 41 further includes two driving cavities which are arranged in the interior of the connecting frame 401 and are symmetrically distributed. The inner wall of each driving cavity is rotationally connected with a mounting shaft, and the surface of the mounting shaft is fixedly connected with uniformly distributed driving blades 4110. The other end of the mounting shaft penetrates out of the driving cavity and is fixedly connected with a transmission mechanism 4108 which is located in the interior of the connecting frame 401. The other ends of the two transmission mechanisms 4108 are fixedly connected with a rotating shaft 4106. The surface of the rotating shaft 4106 and the surface of the connecting shaft are both fixedly connected with bevel gears 4115, and two adjacent bevel gears 4115 are meshingly connected.

[0054] The rotation of the driving blade 4110 can drive the mounting shaft to rotate synchronously. The transmission mechanism 4108 is a mature component in the prior art, which is composed of two transmission wheels and a transmission belt. By driving one of the transmission wheels to rotate, the other transmission wheel can be driven to rotate under the action of the transmission belt. In this process, the transmission mechanism 4108 can drive the rotating shaft 4106 to rotate, and the meshing of the bevel gear 4115 can synchronously drive the connecting shaft to rotate, so as to drive the rotating block 4102 to rotate together with the cleaning rod 4104, thereby improving the cleaning effect on the bottom wall of the pool body 1. This is more in line with the situation that dirt deposition is not conducive to cleaning. The rotation of the cleaning rod 4104 can break up the deposited dirt, making it easier to scrape later.

[0055] As shown in Figures 1-13 The inside of the connecting frame 401 is provided with two symmetrical water pumps 4107. The water inlet end of the water pump 4107 is communicated with a conduit 4101, the other end of the conduit 4101 penetrates out of the connecting frame 401, the water outlet end of the water pump 4107 is communicated with a mounting pipe 4111, and the other end of the mounting pipe 4111 is communicated with a driving cavity. The inside of the driving cavity is provided with a flow guide channel 4109 communicated with an adjacent flow guide cavity 4113.

[0056] Specifically, the water pump 4107 is a booster pump, which can provide water with a large pressure discharged through the mounting pipe 4111.

[0057] The water pump 4107 can extract the sewage inside the pool body 1, inject the sewage into the inside of the driving cavity through the mounting pipe 4111, so that the sewage can drive the driving blade 4110 to rotate the mounting shaft, realize the effect of driving the cleaning rod 4104 to clean, and the sewage in the driving cavity can be injected into the inside of the flow guide cavity 4113 through the flow guide channel 4109, thereby being injected into the inside of the connecting cavity 4105 through the connecting pipe 4103, and being sprayed out through the discharge hole 4112 on the cleaning rod 4104. The high-pressure water flow can be used to strengthen the cleaning effect of the deposited dirt during the rotation of the cleaning rod 4104.

[0058] After the pressure sensor 419 detects that the pressure exceeds the preset value, the signal is transmitted to the controller to stop the motor 32 from outputting, so that the dirt can be stored in the gap between the connecting frame 401 and the scraper 402 under the joint action of the connecting frame 401, the scraper 402, the stop block 410, the sliding plate 418 and the pool body 1. At this time, the high-pressure water flow discharged can push the dirt in the gap out of the discharge port 101 and into the inside of the connecting box 2, and the dirt can be filtered by the filter screen, while the sewage can be re-directed back to the inside of the pool body 1 for treatment through the return pipe 201.

[0059] Further, the inside of the driving cavity can be communicated with the aeration pipe or the dosing pipe, so that the sewage can be mixed when being flushed into the inside of the driving cavity under the action of the water pump 4107, and finally discharged through the discharge port 101 together, thereby enhancing the mixing effect of the aeration or the medicament and the sewage.
