Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figure 1 - Figure 3 , an embodiment provided by the present invention: a coal chemical wastewater treatment device, including a tank body 1. A sewage inlet pipe is provided at the right end of the upper surface of the tank body 1, through which sewage can be smoothly discharged for treatment. A feed pipe 2 is provided at the left end of the upper surface of the tank body 1, through which some chemical particles can be put into the interior of the tank body 1. A stirring rod 5 is rotatably connected through the middle of the upper surface of the tank body 1, and the upper surface of the stirring rod 5 is fixed to the rotating shaft of the motor. The stirring rod 5 is driven by the motor to rotate to stir the wastewater inside the tank body 1, so that the chemical agent and the wastewater can be fully mixed to ensure the effect of cleaning grease. A filter plate 6 is provided on the lower side of the inner wall of the tank body 1 near the stirring rod 5. The filter plate 6 can filter and collect the precipitated grease for subsequent treatment. A collection assembly is provided on the right surface of the bottom end of the tank body 1, and a sealing assembly is provided on the upper surface of the feed pipe 2. The collection assembly includes a collection shell 31 for collecting grease precipitates. The collection shell 31 is slidably connected through the right surface of the bottom end of the tank body 1. A sealing plate 34 is in contact with the left surface of the collection shell 31. When the collection shell 31 is taken out, the sealing plate 34 and the baffle 33 will be driven to move by the hook 35. The sealing plate 34 will seal the insertion hole of the collection shell 31 opened on the right surface of the tank body 1. In this way, the device can be started to treat the wastewater continuously without waiting for the collection shell 31 to be cleaned and installed before processing. The top end of the sealing plate 34 slides inside the inner wall of the filter plate 6. A baffle 33 for sealing the leakage holes opened in the part of the filter plate 6 is fixedly connected to the left surface of the sealing plate 34. The baffle 33 is slidably connected to the inner wall of the bottom end of the filter plate 6. A hook 35 is fixedly connected to the right surface of the sealing plate 34. By means of the hook 35, when the collection shell 31 is taken out, the sealing plate 34 and the baffle 33 can be smoothly driven to move to the right. The left surface of the bottom end of the hook 35 is in contact with the left side of the inner wall of the collection shell 31. Leakage holes are opened on the surfaces of the baffle 33 and the collection shell 31. The density and size of the leakage holes are similar to those of the leakage holes of the filter plate 6 to ensure that the wastewater can flow out smoothly.

[0033] Referring to Figure 1 - Figure 2 、 Figure 5, the sealing assembly includes a cover plate 41 that seals and protects the feed pipe 2 to a certain extent. The lower surface of the left end of the cover plate 41 is rotatably connected to the upper surface of the left end of the feed pipe 2. A pull rod 44 is slidably connected through the upper surface of the cover plate 41. By pulling the pull rod 44, the circular plate 42 can be driven to move, ensuring that the limit of the cover plate 41 can be smoothly contacted. The lower surface of the pull rod 44 is fixedly connected to a circular plate 42. A sealing ring 43 that ensures the sealing performance of the sealing assembly for the feed pipe 2 is fixedly connected to the outer wall of the circular plate 42. The sealing ring 43 slides on the inner wall of the top end of the feed pipe 2.

[0034] Refer to Figure 2 - Figure 4 , the collection assembly further includes a scraper 36 for cleaning the filter plate 6. The scraper 36 is fixedly connected to the front surface of the bottom end of the stirring rod 5. The scraper 36 rotates along with the stirring to ensure the cleaning efficiency. The lower surface of the scraper 36 contacts the upper surface of the filter plate 6. The collection assembly further includes a rotating rod 32. By rotating the rotating rod 32, the limiting plate 38 can be controlled to rotate, facilitating the release of the limit of the limiting plate 38. The rotating rod 32 passes through and is rotatably connected to the top end of the right surface of the collection shell 31. The upper surface of the left end of the rotating rod 32 is fixedly connected to a limiting plate 38 for limiting the collection shell 31. The limiting plate 38 slides on the inner wall of the collection shell 31. A torsion spring 37 is sleeved on the outer wall of the rotating rod 32. The torsion spring 37 has a certain elasticity. Through its own elasticity, it ensures that the limiting plate 38 always maintains a vertical state up and down without rotating the rotating rod 32, ensuring the stability of the limit of the limiting plate 38 for the collection shell 31. One end of the torsion spring 37 is fixedly connected to the front surface of the collection shell 31, and the other end of the torsion spring 37 is fixedly connected to the rear surface of the rotating rod 32. A limiting groove 7 adapted to the left and right width of the limiting plate 38 is provided on the inner wall of the right side of the bottom end of the tank body 1. The limiting plate 38 contacts the inner wall of the limiting groove 7.

[0035] Refer to Figure 2 、 Figure 5 , a spring 45 is sleeved on the outer wall of the pull rod 44. The spring 45 always pulls the pull rod 44 downward through its own elasticity, ensuring that when the cover plate 41 is in the closed state, the sealing ring 43 always contacts the inner wall of the sealing groove 8, ensuring the sealing effect. One end of the spring 45 is fixedly connected to the upper surface of the cover plate 41, and the other end of the spring 45 is fixedly connected to the lower surface of the pull rod 44. A sealing groove 8 is provided on the inner wall of the top end of the feed pipe 2, and a set of sealing grooves 8 are also provided on the inner wall of the cover plate 41, ensuring that when the pull rod 44 is pulled, the sealing ring 43 can smoothly disengage from the inner wall of the feed pipe 2 and enter the inner wall of the cover plate 41. The outer wall of the sealing ring 43 contacts the inner wall of the sealing groove 8. The sealing ring 43 is made of rubber material and has a certain elasticity. At the same time, its outer wall is set as an arc surface to ensure that it can be smoothly stuck in the inner wall of the sealing groove 8.

[0036] Working principle: Sewage is discharged into the interior of the tank body 1 through the sewage inlet pipe at the right end of the upper surface of the tank body 1. Chemical agents are put into the tank body 1 through the feed pipe 2. When putting in chemical agents, the pull rod 44 can be pulled upward to drive the circular plate 42 and the sealing ring 43 to move, so that the sealing ring 43 disengages from the sealing groove 8 on the inner wall of the top end of the feed pipe 2 through its rubber elasticity. Then the cover plate 41 can be rotated to open it, and thus feeding can be carried out. After feeding is completed, the cover plate 41 is rotated back, and then the pull rod 44 is released. The spring 45 pulls the pull rod 44 to move downward, so that the sealing ring 43 enters the sealing groove 8 to ensure the sealing of the feed pipe 2 and prevent the exhaust gas generated by the wastewater inside the tank body 1 from being discharged. The motor drives the stirring rod 5 to rotate to stir the wastewater inside the tank body 1, so that the chemical agent and the wastewater are fully mixed to clean the grease.

[0037] The stirred wastewater is filtered by the filter plate 6, and the precipitated grease is intercepted by the filter plate 6. When the stirring rod 5 rotates, it drives the scraper 36 to rotate, and the scraper 36 cleans the filter plate 6 and scrapes the precipitate into the collection shell 31.

[0038] When it is necessary to handle the precipitate in the collection shell 31, the rotating rod 32 is rotated to drive the limiting plate 38 to rotate, releasing the limit of the collection shell 31 by the limiting plate 38. Then the collection shell 31 is pulled out to the right. When the collection shell 31 is taken out, the sealing plate 34 and the baffle 33 are driven to move by the hook 35. The sealing plate 34 seals the insertion hole of the collection shell 31 opened on the right surface of the tank body 1, so that the device can continue to start to treat the wastewater without waiting for the collection shell 31 to be cleaned and installed and then continuing to clean the wastewater, ensuring that while the collection shell 31 is being cleaned, the device can also operate normally.

[0039] During installation, the rear surface of the collection shell 31 is made to contact and overlap with the front surface of the sealing plate 34. At this time, the left surface of the bottom end of the hook 35 will contact the left side of the inner wall of the collection shell 31. Then the collection shell 31 is pushed to make it enter the interior of the tank body 1, and the sealing plate 34 and the baffle 33 will also reset accordingly. Before the collection shell 31 is completely inserted into the inner wall of the tank body 1, the rotating rod 32 can be rotated to make the limiting plate 38 rotate and hide in the inner wall of the right end of the collection shell 31. At the same time, the rotating rod 32 will drive the torsion spring 37 to twist and deform until the collection shell 31 is completely inserted into the interior of the tank body 1. At this time, the limiting plate 38 will overlap with the limiting groove 7. The rotating rod 32 is released, and the torsion spring 37 will drive the rotating rod 32 to rotate reversely for reset through its own elasticity, and the limiting plate 38 will also be stuck on the inner wall of the limiting groove 7 to limit the collection shell 31.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
