[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0019] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0020] As Figures 1 - 13 shown, an industrial sewage treatment pool and a sewage treatment method include a pool body 1 and a controller. A connection box 2 is provided on one side of the pool body 1. A filter screen is fixedly connected to the inner wall of the connection box 2. A return pipe 201 communicating with the pool body 1 is provided on the surface of the connection box 2. A water injection pipe is communicated with one side of the pool body 1, and a water outlet pipe is communicated with the other side of the pool body 1. A motor 32 is provided on one side of the top of the pool body 1. The output shaft of the motor 32 is fixedly connected with a threaded rod 3. A guide rod 31 symmetrically distributed with the threaded rod 3 is fixedly connected to the top of the pool body 1. A cleaning module 4 is arranged inside the pool body 1. A drain outlet 101 is opened on the surface of the pool body 1 above the connection box 2; The cleaning module 4 includes a scraping structure for cleaning the dirt on the inner wall of the pool body 1, and an auxiliary structure 41 for discharging the dirt is arranged on the surface of the scraping structure; Among them, the scraping structure includes a connection frame 401 arranged inside the pool body 1. The cross-sectional shape of the connection frame 401 is U-shaped. A scraper 402 is fixedly connected to one side of the connection frame 401. The outer side of the scraper 402 is in contact with the inner wall of the pool body 1. Uniformly distributed through grooves 403 are opened on the surface of the scraper 402.

[0021] Both ends of the connecting frame 401 are fixedly connected with sliders 404. The upper ends of the two sliders 404 penetrate through the pool body 1. One of the sliders 404 is threadedly connected to the surface of the threaded rod 3, and the other slider 404 is slidably connected to the surface of the guide rod 31.

[0022] By starting the motor 32, the rotation of the output shaft can drive the threaded rod 3 to rotate, thereby driving the slider 404 threadedly connected thereto to move along the threaded rod 3. During this process, the arrangement of the other slider 404 and the guide rod 31 can cooperate with the connecting frame 401 to ensure that the slider 404 will not rotate with the threaded rod 3. At the same time, by controlling the positive and reverse rotation of the output shaft of the motor 32, the moving direction of the slider 404 can be changed.

[0023] As Figures 1 - 13 shown, a sliding plate 418 is slidably connected to the inner side of the connecting frame 401. One side of the sliding plate 418 is fixedly connected with a return spring 417. A pressure sensor 419 is arranged on the inner wall of the connecting frame 401. A buffer block is arranged on the surface of the pressure sensor 419. One end of the return spring 417 is fixedly connected to the surface of the buffer block. Block 410s are arranged on the outer side of the connecting frame 401 and are evenly distributed and correspond to the through grooves 403. The cross-sectional shape of the block 410 is a right trapezoid. Adjustment cavities 413 are evenly distributed and correspond to the block 410s in the interior of the connecting frame 401. A sliding plate 412 is slidably connected to the inner wall of the adjustment cavity 413. A sliding rod 414 is fixedly connected to the surface of the sliding plate 412. One end of the sliding rod 414 penetrates through the connecting frame 401 and is fixedly connected to the surface of the adjacent block 410. A second spring 415 is fixedly connected between the sliding plate 412 and the inner wall of the adjustment cavity 413.

[0024] A liquid storage cavity 405 is opened in the connecting frame 401. An adjusting rod 406 is arranged inside the liquid storage cavity 405. One end of the adjusting rod 406 penetrates through the connecting frame 401. The other end of the adjusting rod 406 sequentially penetrates through the connecting frame 401 and the scraping plate 402. An extrusion plate 416 slidably connected to the inner wall of the liquid storage cavity 405 is fixedly connected to the surface of the adjusting rod 406. A storage cavity is formed between one side of the extrusion plate 416 and the inner wall of the liquid storage cavity 405. The storage cavity is filled with hydraulic oil. A connecting channel 411 for communicating a plurality of adjustment cavities 413 is opened in the connecting frame 401. One end of the connecting channel 411 is communicated with the storage cavity.

[0025] A storage cavity is opened on the inner top wall of the liquid storage cavity 405. A limiting rod 408 is slidably connected to the inside of the storage cavity. A first spring 407 is fixedly connected between the upper end of the limiting rod 408 and the inner wall of the storage cavity. Two limiting grooves 409 are opened on the surface of the adjusting rod 406. The lower end of the limiting rod 408 penetrates through the storage cavity and extends into the limiting groove 409, and the lower end of the limiting rod 408 is arranged in a hemispherical shape.

[0026] When the connecting frame 401 moves towards the motor 32, the position of the stopper 410 is as shown Figure 3 in the figure. Thus, the scraper 402 scrapes the dirt on the inner wall of the pool body 1 along the moving direction, reducing the influence of dirt adhesion on the inner wall of the pool body 1 on the sewage treatment effect. At the same time, due to the setting of the through groove 403, the scraped dirt is guided to the other side of the scraper 402 through the through groove 403 under the action of the water flow pushed during the movement of the scraper 402, preventing the pushed dirt from sticking tightly to the other inner wall of the pool body 1. Until the scraper 402 is in close contact with the inner wall of the pool body 1, due to the blockage of the inner wall of the pool body 1, the adjusting rod 406 and the pressing plate 416 are pushed to move synchronously, causing the pressing plate 416 to squeeze the hydraulic oil stored in the storage cavity. The squeezed hydraulic oil is injected into the inside of the adjusting cavity 413 through the connecting channel 411, thereby pushing the sliding plate 412 to slide along the inner wall of the adjusting cavity 413 and driving the sliding rod 414 to move the stopper 410 synchronously to block the through groove 403, while compressing the second spring 415. And by reversing the output shaft of the motor 32, the connecting frame 401 moves in the reverse direction. During this process, the position that could not be cleaned at the original through groove 403 can be scraped by the stopper 410. And after moving to the other inner wall and the sliding plate 418 contacts the inner wall, the pressure sensor 419 is pressed. 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, the scraper 402, the stopper 410, the sliding plate 418 and the pool body 1, the dirt can be stored in the gap between the connecting frame 401 and the scraper 402, and this gap can communicate with the discharge port 101, facilitating subsequent cleaning through the auxiliary structure 41.

[0027] After waiting for fifteen minutes for 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, and then the output shaft of the motor 32 rotates forward, thereby driving the connecting frame 401 to reset and clean again. And under the blockage of the other inner wall of the pool body 1, the adjusting rod 406 and the pressing plate 416 are pushed to reset. At this time, due to the reset of the pressing plate 416, the space in the storage cavity increases, and the sliding plate 412 can be driven to reset under the action of the second spring 415 and squeeze the hydraulic oil back into the inside of the storage cavity, so that the stopper 410 no longer blocks the through groove 403.

[0028] The setting of the limiting groove 409 and the limiting rod 408 can limit the position of the adjusting rod 406 after the adjusting rod 406 is adjusted by the two inner walls of the pool body 1. And under the action of the first spring 407, the lower end of the limiting rod 408 closely adheres to the inner wall of the limiting groove 409, preventing the position of the adjusting rod 406 from shifting during the movement. The lower end of the limiting rod 408 is hemispherical, which can facilitate the adjustment of the position of the adjusting rod 406 by being jacked up by the extrusion of the inner wall of the pool body 1.

[0029] As shownFigures 1 - 10 As shown, the auxiliary structure 41 includes three rotating blocks 4102 arranged at the bottom of the connecting frame 401. A connecting shaft is fixedly connected to the top of the rotating block 4102. The upper end of the connecting shaft penetrates into the interior of the connecting frame 401 and is rotatably connected to the inner wall of the connecting frame 401. A connecting cavity 4105 is formed inside the rotating block 4102. Uniformly distributed cleaning rods 4104 communicating with the connecting cavity 4105 are arranged at the bottom of the rotating block 4102. Discharge holes 4112 are uniformly distributed on the lower end surface of the cleaning rod 4104.

[0030] Three diversion cavities 4113 coaxial with the three rotating blocks 4102 are formed inside the connecting frame 401. A flow channel 4114 for communicating two adjacent diversion cavities 4113 is formed inside the connecting frame 401. A connecting pipe 4103 is eccentrically connected to the top of the rotating block 4102. The upper end of the connecting pipe 4103 penetrates through the connecting frame 401 and is connected to the diversion cavity 4113.

[0031] The auxiliary structure 41 further includes two symmetrically distributed driving cavities formed inside the connecting frame 401. A mounting shaft is rotatably connected to the inner wall of the driving cavity. Uniformly distributed driving blades 4110 are fixedly connected to the surface of the mounting shaft. The other end of the mounting shaft penetrates out of the driving cavity and is fixedly connected to a transmission mechanism 4108 located inside the connecting frame 401. A rotating shaft 4106 is fixedly connected between the other ends of the two transmission mechanisms 4108. Bevel gears 4115 are fixedly connected to the surfaces of the rotating shaft 4106 and the connecting shaft, and two adjacent bevel gears 4115 are meshed.

[0032] The rotation of the driving blade 4110 can drive the mounting shaft to rotate synchronously. The transmission mechanism 4108 is a relatively mature component in the existing technical applications, consisting of two transmission wheels and a transmission belt. By driving the rotation of one of the transmission wheels, the other transmission wheel can be driven to rotate under the action of the transmission belt. During this process, the transmission mechanism 4108 can be used to drive the rotating shaft 4106 to rotate, and the bevel gears 4115 can be used to synchronously drive the connecting shaft to rotate, so as to drive the rotating block 4102 to rotate the cleaning rod 4104 together, improving the cleaning effect on the inner bottom wall of the pool body 1, which is more in line with the situation that dirt deposition is not conducive to cleaning. The rotation of the cleaning rod 4104 can break the deposited dirt, making it convenient for subsequent scraping.

[0033] As Figures 1 - 13As shown in the figure, there are two symmetrically distributed water pumps 4107 inside the connecting frame 401. The water inlet ends of the water pumps 4107 are connected to a conduit 4101, and the other end of the conduit 4101 penetrates out of the connecting frame 401. The water outlet ends of the water pumps 4107 are connected to an installation pipe 4111, and the other end of the installation pipe 4111 is connected to the driving cavity. A diversion channel 4109 communicating with the adjacent diversion cavity 4113 is opened inside the driving cavity.

[0034] Specifically, the water pump 4107 is a booster pump, which can discharge water with a relatively large pressure through the installation pipe 4111.

[0035] The water pump 4107 can extract the sewage inside the pool body 1, inject the sewage into the driving cavity through the installation pipe 4111, so that the sewage can push the driving blade 4110 to rotate the installation shaft, achieving the effect of driving the cleaning rod 4104 to clean. And the sewage in the driving cavity can be injected into the diversion cavity 4113 through the diversion channel 4109, and then can be injected into the connecting cavity 4105 through the connecting pipe 4103 and ejected through the discharge holes 4112 on the cleaning rod 4104, which can strengthen the cleaning effect on the deposited dirt by using high-pressure water flow during the rotation of the cleaning rod 4104.

[0036] 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. Thus, under the combined action of the connecting frame 401, the scraper 402, the stopper 410, the sliding plate 418 and the pool body 1, the dirt can be stored in the gap between the connecting frame 401 and the scraper 402. At this time, the discharged high-pressure water flow can push the dirt in this gap out of the discharge port 101 and introduce it into the connecting box 2, and the dirt is filtered by the filter screen, while the sewage can be re-introduced into the pool body 1 through the return pipe 201 for treatment.

[0037] Furthermore, an aeration pipe or a chemical dosing pipe can be connected to the inside of the driving cavity, which can mix the sewage when it is flushed into the driving cavity under the action of the water pump 4107 and finally discharge it together through the discharge port 101, strengthening the aeration or the mixing effect of the chemical agent and the sewage.

Pretreat the sewage, and intercept and clean the floating garbage and large impurities in the sewage in the form of a grille; S2. The pretreated sewage is introduced into the inside of the pool body 1 through an injection pipe, and a flocculant is added to make its fine particles aggregate and precipitate; S3. Use the cleaning module 4 to separately discharge the precipitated impurities and dirt, and finally introduce the sewage into the next treatment process through the water outlet pipe.
