Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a plate and frame sludge interception and dewatering device. Background Technology

[0002] Globally, governments are strengthening the enforcement of environmental regulations, imposing stricter standards and requirements on wastewater and sludge treatment. With increasing public awareness of environmental protection, societal attention to wastewater and sludge treatment is also growing. Given the increasing scarcity of global resources, sludge treatment is no longer merely a waste disposal issue, but also a matter of resource recycling and reuse. Improved plate-and-frame sludge interception and dewatering systems can more effectively recover water resources and other valuable substances from sludge, which is of great significance for resource conservation and the development of a circular economy.

[0003] During operation, existing plate and frame filter presses suffer from sludge adhesion to the hydraulic water-blocking flaps when they are wet. This causes the flaps to exceed their own weight, resulting in wear, reduced strength, and corrosion and perforation due to long-term sludge exposure. This necessitates frequent maintenance, increases the risk of occupational diseases, and raises the operating costs of the plant.

[0004] Therefore, to address the problems of existing plate and frame filter presses during operation, where sludge adheres to the hydraulic water-blocking flaps in wet conditions, easily leading to the flaps exceeding their own weight and causing corrosion and perforation, requiring frequent maintenance, increasing the risk of occupational diseases, and raising plant operating costs, a plate and frame sludge interception and dewatering device can be designed. This device incorporates bearing seats, a rotating shaft, a mounting sleeve, hydraulic rods, and a resin anti-corrosion coating. The hydraulic rods provide support and cushioning to the inner side of the flap body, while the resin anti-corrosion coating effectively isolates sludge and moisture, preventing their adhesion to the flap body surface, thus delaying corrosion and ensuring the service life of the flap body. Utility Model Content

[0006] The technical solution of this utility model is as follows: a plate and frame type sludge interception and dewatering device, including a base plate; mounting frames are connected to the four corners of the top of the base plate, bearing seats are provided on the top of the mounting frames, a rotating shaft is installed inside the bearing seats, a mounting sleeve is sleeved on the end of the rotating shaft away from the mounting frame, a flap body is connected between the left and right mounting sleeves, a collection box is connected to the outside of the flap body, connecting rods are connected to the left and right sides of the flap body, a rotating seat is connected to the outside of the connecting rods, a hinge seat is connected to the lower inner end of the mounting frame, a hydraulic rod is hinged inside the hinge seat, the output end of the hydraulic rod is sleeved on the outside of the rotating seat, and a resin anti-corrosion coating is provided on the top of the flap body.

[0007] Preferably, the hydraulic rod can pull the flap body to rotate around the rotating shaft. The resin anti-corrosion coating has good adhesion and hydrophobicity, which can effectively isolate sludge and water, allowing the sludge and water to slide into the collection box and avoid adhering to the surface of the flap body, thereby delaying the corrosion process. The flap body is driven to flip by the hydraulic rod, which can work with the bearing seat to provide stable support for the flap body. When the flap body is impacted by the top sludge, it can also play a certain buffering role, thereby ensuring the service life of the flap body.

[0008] Preferably, the top of the inner part of the mounting sleeve is connected to a positioning protrusion, and the top of the rotating shaft facing the end of the mounting sleeve is provided with a positioning groove, and the positioning protrusion and the positioning groove are matched with each other.

[0009] Preferably, the bottom of the bearing housing is connected to a mounting base, and the top left and right sides of the mounting base are provided with screw holes.

[0010] Preferably, screw holes two are provided on both the left and right sides of the top of the mounting bracket, and screw holes two match screw holes one.

[0011] Preferably, the top left and right sides of the base plate are provided with support legs, and the top of the support legs are connected to the frame.

[0012] Preferably, the bottom of the support leg is connected to a mounting plate, which is installed on the top of the base plate. Reinforcing ribs are connected to the top left and right sides of the mounting plate, and the other end of the reinforcing ribs is connected to the left and right sides of the support leg.

[0013] Preferably, five support plates are connected to the top left and right sides of the base plate, and an electric conveyor belt is installed on the top of the support plates. The electric conveyor belt is located at the lower end of the flip plate body.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up bearing seats, rotating shafts, mounting sleeves, hydraulic rods, and resin anti-corrosion coatings, activating the hydraulic rods, in conjunction with the rotating shafts, drives the flap body to rotate. The hydraulic rods provide support to the inner side of the flap body and also cushion the flap body when it is impacted by sludge blocks falling from above. The surface of the flap body is coated with a resin anti-corrosion coating, which has good adhesion and hydrophobicity, effectively isolating sludge and moisture. This allows sludge and moisture to slide into the collection box, preventing them from adhering to the surface of the flap body, thus delaying the corrosion process and ensuring the service life of the flap body.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment of a plate-and-frame sludge interception and dewatering device, comprising a base plate 1; mounting frames 2 are connected to the four corners of the top of the base plate 1, bearing seats 3 are provided on the top of the mounting frames 2, a rotating shaft 4 is installed inside the bearing seats 3, a mounting sleeve 5 is sleeved on the end of the rotating shaft 4 away from the mounting frames 2, a flap body 6 is connected between the left and right mounting sleeves 5, a collection box 7 is connected to the outside of the flap body 6, connecting rods 8 are connected to the left and right sides of the flap body 6, a rotating seat 11 is connected to the outside of the connecting rods 8, a hinge seat 9 is connected to the lower inner side of the mounting frame 2, a hydraulic rod 10 is hinged inside the hinge seat 9, and the output end of the hydraulic rod 10 is sleeved on the outside of the rotating seat 11. The top of the flap body 6 is provided with a resin anti-corrosion coating 23. The hydraulic rod 10 can pull the flap body 6 to rotate around the rotating shaft 4. The resin anti-corrosion coating 23 has good adhesion and hydrophobicity, which can effectively isolate sludge and water, allowing the sludge and water to slide into the collection box 7, preventing them from adhering to the surface of the flap body 6, thereby delaying the corrosion process. The flap body 6 is driven to flip by the hydraulic rod 10. The hydraulic rod 10 can cooperate with the bearing seat 3 to provide stable support for the flap body 6. When the flap body 6 is impacted by the top sludge, it can also play a certain buffering role, thereby ensuring the service life of the flap body 6.

[0025] Please see Figures 3-4 In this embodiment, a positioning protrusion 12 is connected to the top of the inner part of the mounting sleeve 5. A positioning groove 13 is provided on the top of the rotating shaft 4 facing the mounting sleeve 5. The positioning protrusion 12 and the positioning groove 13 match each other. A mounting base 14 is connected to the bottom of the bearing seat 3. Screw holes 15 are provided on the left and right sides of the top of the mounting base 14. Screw holes 26 are provided on the left and right sides of the top of the mounting bracket 2. Screw holes 26 match screw holes 15. Align the screw holes 15 on the mounting base 14 with the screw holes 26 on the mounting bracket 2. Then, the mounting base 14 can be installed on the mounting bracket 2 with bolts, thereby completing the installation of the bearing seat 3. Install one end of the rotating shaft 4 on the bearing seat 3. Insert the other end of the rotating shaft 4 into the inside of the mounting sleeve 5 through the positioning groove 13 and the positioning protrusion 12, thereby completing the installation of the flip plate body 6. The bearing seat 3 can play a stable supporting role when the flip plate body 6 rotates.

[0026] Please see Figures 1-6In this embodiment, support legs 17 are provided on the top left and right sides of the base plate 1. The top of the support legs 17 is connected to the frame 18, and the bottom of the support legs 17 is connected to the mounting plate 19. The mounting plate 19 is installed on the top of the base plate 1. The top left and right sides of the mounting plate 19 are connected to the reinforcing ribs 20. The other end of the reinforcing ribs 20 is connected to the left and right sides of the support legs 17. Five support plates 22 are connected on the top left and right sides of the base plate 1. An electric conveyor belt 21 is installed on the top of the support plate 22. The electric conveyor belt 21 is located at the lower end of the flip plate body 6. The support legs 17 and the mounting plate 19 can play a role in stabilizing the frame 18. The frame 18 facilitates the installation of the plate and frame filter press. When it is necessary to transport the filtered sludge blocks, the flip plate body 6 is opened, and the sludge blocks on the filter plate can fall onto the electric conveyor belt 21 through the flip plate body 6. The electric conveyor belt 21 can then transport the sludge blocks to the designated place for processing.

[0027] During operation, the hydraulic rod 10 pulls the flap body 6 to rotate around the rotating shaft 4. The resin anti-corrosion coating 23 has good adhesion and hydrophobicity, which can effectively isolate sludge and water, allowing the sludge and water to slide into the collection box 7, preventing them from adhering to the surface of the flap body 6, thereby delaying the corrosion process and ensuring the service life of the flap body 6. The flap body 6 is driven to flip by the hydraulic rod 10. The hydraulic rod 10, together with the bearing seat 3, can provide stable support for the flap body 6. When the flap body 6 is impacted by the top sludge, it can also play a certain buffering role, thereby ensuring the service life of the flap body 6. When it is necessary to transport sludge blocks, the hydraulic rod 10 is activated to flip the flap body 6 downward, adjusting the flap body 6 to the upper end of the electric conveyor belt 21. Then the filter plate can be opened, and the sludge blocks can fall onto the electric conveyor belt 21 through the flap body 6. The electric conveyor belt 21 can then transport the sludge blocks to the designated location for processing.

[0028] Through the above steps, by setting bearing seat 3, rotating shaft 4, mounting sleeve 5, hydraulic rod 10 and resin anti-corrosion coating 23, the hydraulic rod 10 can support the inner side of the flap body 6 and provide a certain buffering effect. The surface of the flap body 6 is coated with resin anti-corrosion coating 23, which can effectively isolate sludge and moisture, preventing them from adhering to the surface of the flap body 6, thereby delaying the corrosion process and ensuring the service life of the flap body 6. This solves the problem that in the operation of existing plate and frame filter presses, when sludge adheres to the hydraulic water-blocking flap in a wet state, it is easy for the flap to exceed its own weight and corrode and perforate, requiring frequent maintenance, increasing the risk of occupational diseases and increasing the operating cost of the plant.
