Description

Technical Field

[0001] This utility model relates to the field of sludge separation equipment, specifically a sludge separation device for sewage treatment. Background Technology

[0002] Wastewater refers to water bodies polluted by domestic and industrial production activities. It contains a large amount of organic matter, suspended solids, heavy metals and other harmful substances. Direct discharge of wastewater will cause serious harm to the ecological environment and human health. Wastewater treatment is an important part of environmental protection. Sludge separation is a key step. Solid-liquid separation can effectively reduce the volume of sludge, making it easier for subsequent treatment or resource utilization.

[0003] Existing sludge separation equipment is inconvenient to use, with a complex internal structure and cumbersome operation. The sludge separation and filtration speed is slow, and the collection of impurities after separation is inconvenient, requiring manual cleaning, which increases labor intensity and may also cause secondary pollution.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0024] In one embodiment, such as Figure 1-5 As shown, a sewage treatment sludge separation device includes a protective box 1, and further includes:

[0025] The protective box 1 has a support box 2 at its bottom, an installation groove 101 inside, a fixing block 16 inside the installation groove 101, a fixing frame 3 on the fixing block 16, a support frame 4 rotatably mounted on the side wall of the fixing frame 3, a screen 15 for separating sludge inside the support frame 4, a collection box 27 for collecting impurities on the outer side wall of the protective box 1, grooves 401 on both sides of the support frame 4, movable blocks 17 slidably mounted inside the grooves 401, a scraper 9 between the two movable blocks 17, the scraper 9 contacting the top of the screen 15, the scraper 9 sliding left and right and scraping the sludge to prevent the sludge from adhering to the screen 15;

[0026] The filter press box 7 is provided inside the protective box 1, which is equipped with a guide plate 5 and a collection box 6. The side wall of the collection box 6 is equipped with a filter cylinder 8. The filtered sewage is discharged outward from the filter cylinder 8. The collection box 6 is equipped with a filter press box 7. The guide plate 5 has a through groove 501 inside. The filter press box 7 is located below the through groove 501. Square grooves 701 are provided on both sides of the outside of the filter press box 7. Filter screens 26 are provided inside the square grooves 701. A sealing plate 18 is slidably arranged inside the filter press box 7.

[0027] The lifting mechanism is connected to the sealing plate 18 and can drive the sealing plate 18 to move up and down along the inner wall of the filter press box 7.

[0028] The wastewater treatment sludge separation device uses a lifting mechanism to move the sealing plate 18 up and down along the inner wall of the filter press box 7. Wastewater flows downward along the screen 15, which performs preliminary filtration. The screen is cleaned by the scraper 9 to prevent clogging. Then, the wastewater flows into the filter press box 7. Driven by the lifting mechanism, the sealing plate 18 is pressed down, allowing the wastewater to be discharged through the filter screen 26. The sludge residue is compressed and retained, making it easier to clean later. This improves the wastewater separation speed and reduces the difficulty of manual cleaning. As an example, the left, right, up, and down positions of the various components shown in the attached drawings are only one arrangement. The specific positions are set according to specific needs.

[0029] In one embodiment, such as Figure 1-4 As shown, the lifting mechanism includes a lifting rod 19, a connecting plate 23, and a rotating plate 22. The bottom of the protective box 1 is provided with a guide rail 20. Two symmetrical sliders 21 are slidably arranged inside the guide rail 20. The rotating plate 22 is rotatably arranged on the sliders 21. The bottom of the sealing plate 18 is provided with a lifting rod 19. A connecting plate 23 is arranged between the bottom ends of the two lifting rods 19. One end of the rotating plate 22 is rotatably connected to the connecting plate 23. The sliders 21 move closer to each other and drive the rotating plate 22 to rotate. The rotating plate 22 drives the connecting plate 23 to descend. The connecting plate 23 drives the sealing plate 18 to descend through the lifting plate 19. That is, the sliders 21 move along the guide rail 20, and the rotating plate 22 rotates accordingly, thereby pushing the connecting plate 23 and the sealing plate 18 to rise and fall.

[0030] In one embodiment, such as Figure 1-5 As shown, a lead screw 25 is provided inside the guide rail 20, and the two ends of the lead screw 25 are provided with external threads with opposite directions of rotation. The slider 21 is provided with a threaded groove that cooperates with the lead screw 25. A power component 24 for driving the lead screw 25 to rotate is provided outside the guide rail 20. The lead screw 25 rotates and drives the two sliders 21 to move closer or further apart.

[0031] In one embodiment, such as Figure 1-3 As shown, a fixing plate 11 is provided on the outer wall of the protective box 1, and a rotating sleeve 12 is provided on the fixing plate 11. A telescopic rod 13 is elastically installed inside the rotating sleeve 12. A connecting block 14 is provided at one end of the telescopic rod 13. The connecting block 14 is located inside the support frame 4. The support frame 4 below is suspended by the rotating sleeve 12 and the telescopic rod 13.

[0032] In one embodiment, such as Figure 1-2 As shown, the fixing plate 11 is provided with a plurality of fixing screws 10, one end of which is inserted into the interior of the protective box 1.

[0033] The above embodiments of this utility model provide a sewage treatment sludge separation device. The sewage to be treated is poured into the top of the protective box 1. The sewage first flows to the surface of the screen 15. The sewage undergoes preliminary solid-liquid separation through the screen 15. Larger sludge particles are trapped on the screen surface and slide into the collection box 27. The pre-filtered sewage flows into the filter press box 7 below through the through groove 501 of the guide plate 5 (at this time, the sealing plate 18 is located above the top of the filter press box 7). The power component 24 drives the lead screw 25 to rotate. Since the threads at both ends of the lead screw 25 rotate in opposite directions, the two sliders 21 move synchronously towards each other along the guide rail 20. The sliders 21 drive the rotating plate 22 to rotate, the connecting plate 23 and the lifting rod 19 move down, and the sealing plate 18 descends accordingly, applying pressure to the sewage in the filter press box 7. The pressurized sewage is discharged through the filter screens 26 on both sides of the filter press box 7 and enters the collection box 6. Finally, it flows out through the filter cylinder 8. The solid sludge is compressed and retained in the filter press box 7. The filter press box 7 is opened (or through the bottom discharge port) to remove the compressed solid sludge.

[0034] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
