[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A sludge removal device for industrial wastewater treatment includes a treatment tank 1. A top frame 2 is fixedly installed at the upper part of the interior of the treatment tank 1, and a bottom frame 3 is fixedly installed at the lower part of the interior of the treatment tank 1. An opening and closing mechanism is provided between the top frame 2 and the bottom frame 3. The opening and closing mechanism includes a movable frame 7, which is movably connected to the lower part of the exterior of the top frame 2. The inner wall of the movable frame 7 is slidably connected to the exterior of the top frame 2. Electric actuators 8 are fixedly installed at the top of the treatment tank 1 and on both sides of the top frame 2. The output shaft of the electric actuators 8 is fixedly connected to the movable frame 7. The opening and closing mechanism also includes... Includes a plug rod 9, a plug rod 9 matching the filter hole 4 is fixedly connected to the bottom upper surface of the movable frame 7, an opening 21 matching the opening 1 5 is opened in the middle of both sides of the movable frame 7, a through hole 20 is opened at the bottom of the movable frame 7 and between several plug rods 9, a drain pipe 16 is connected to the middle of the bottom of the processing box 1, the upper end of the drain pipe 16 is connected to the inside of the bottom frame 3, a guide plate 2 17 is fixedly installed on both sides of the bottom of the bottom frame 3, and an opening 3 18 is provided between the guide plate 2 17 and the inner side of the bottom of the processing box 1.

[0027] In this embodiment, during the filtration process, the movable frame 7 is lowered by the action of the electric push rod 8, causing the blocking rod 9 at the bottom of the movable frame 7 to retract from the filter hole 4 of the top frame 2, ensuring that the filter hole 4 remains open. At the same time, the lower end face of the movable frame 7 abuts against the upper end face of the bottom frame 3, preventing sewage from leaking from both sides of the top frame 2, and avoiding sludge or small-volume impurities from being squeezed into the through hole 20, thereby effectively preventing the through hole 20 from becoming clogged.

[0028] like Figure 2 and Figure 3 As shown, several filter holes 4 are regularly arranged at the bottom of the top frame 2. Openings 5 ​​are provided on the lower outer sides of both sides of the top frame 2. A cleaning mechanism is provided on the upper right side of the processing box 1. The cleaning mechanism includes a bracket 12. The bracket 12 is fixedly installed on the upper outer side of the right side of the processing box 1. An electric push rod 13 is fixedly installed on the top of the bracket 12. The output shaft of the electric push rod 13 passes through the processing box 1 and a triangular scraper 14 is fixedly installed. The triangular scraper 14 and the opening 5 are on the same horizontal line. A guide plate 15 is fixedly installed on the lower outer sides of both sides of the movable frame 7. A side groove 6 is provided on the lower outer sides of both sides of the processing box 1. A collection mechanism is provided inside the side groove 6. The collection mechanism includes a waste box 19. The waste box 19 is movably installed inside the side groove 6. A handle 10 is fixedly installed on the outer side of the waste box 19. The side groove 6 is connected to the opening 18.

[0029] In this embodiment, during the cleaning process, the electric push rod 8 drives the movable frame 7 to rise, causing the blocking rod 9 to block the filter hole 4, ensuring that the filter hole 4 remains closed during the cleaning process. At the same time, the rise of the movable frame 7 causes the opening 5 to overlap with the opening 11, providing a channel for the cleaning work. The electric push rod 13 drives the triangular scraper 14 to move, cleaning the sludge and debris on the upper bottom surface of the top frame 2, and guiding the impurities into the waste box 19 through the guide plate 15 and the guide plate 17.

[0030] Working principle: During operation, the movable frame 7 first descends under the action of the electric push rod 8, so that the lower end of the movable frame 7 abuts against the upper end of the bottom frame 3. This action causes the openings 5 ​​on both sides of the top frame 2 to be misaligned with the openings 11 on both sides of the movable frame 7. As the movable frame 7 descends, the blocking rod 9 at the bottom of the movable frame 7 and the filter hole 4 of the top frame 2 retract, and the industrial wastewater is introduced into the top of the treatment tank 1. The sewage enters the interior of the movable frame 7 through the filter hole 4 and passes through the through hole 20 at the bottom of the movable frame 7 into the bottom frame 3. This process ensures that sludge and debris are effectively intercepted in the movable frame 7, while the filtered water is discharged through the drain pipe 16. When cleaning is required, the electric actuator 8 drives the movable frame 7 to rise, causing the blocking rod 9 to block the filter hole 4. The blocking rod 9 and the upper end of the filter hole 4 are on the same horizontal line, ensuring that the filter hole 4 remains closed during the cleaning process. At the same time, the rise of the movable frame 7 causes the opening 1 5 and the opening 2 11 to overlap, providing a channel for the cleaning work. Next, the electric actuator 2 13 drives the triangular scraper 14 to move, cleaning the sludge and debris on the upper bottom surface of the top frame 2. During the cleaning process, the sludge and debris are pushed by the triangular scraper 14 and enter the guide plates 15 on both sides of the movable frame 7 through the opening 1 5 and the opening 2 11. Finally, they enter the waste box 19 in the side groove 6 through the guide plate 2 17 and the opening 3 18.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
