Description

Technical Field

[0001] This utility model relates to the field of filter belt technology, specifically a filter belt for rapid dewatering of sludge. Background Technology

[0002] In the field of sludge treatment, filter belts are a key component in the rapid dewatering process of sludge, and their surface cleanliness directly affects dewatering efficiency and subsequent treatment effects. Currently, the cleaning of filter belts mostly adopts traditional methods: first, the sludge adhering to the surface of the filter belt is scraped off with a scraper, and then the surface of the belt is rinsed with clean water using a spray nozzle; However, this cleaning method has obvious limitations: on the one hand, the scraper can only remove the thicker sludge layer on the surface of the mesh belt, and it is difficult to completely remove the fine sludge particles or sticky substances that have seeped into the mesh belt pores; on the other hand, the water flow sprayed by the nozzle often only acts on the surface of the mesh belt and is difficult to penetrate into the pores, resulting in the gradual accumulation of residual sludge. Over time, the pores of the filter mesh belt are easily blocked, which not only reduces the sludge dewatering efficiency, but also affects the stability of the filtration effect, and increases the frequency and cost of equipment maintenance. Therefore, this patent proposes a filter mesh belt for rapid sludge dewatering to solve the above problems. Utility Model Content

[0013] 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.

[0014] In the field of sludge treatment, filter belts are key components in the rapid dewatering process of sludge, and their surface cleanliness directly affects the dewatering efficiency and subsequent treatment effects.

[0015] like Figures 1-4As shown, this utility model provides a technical solution: a filter belt for rapid dewatering of sludge, including a support frame 1. A first filter belt 2 and a second filter belt 3 are disposed between the inner walls of both sides of the support frame 1. A first scraper 18 and a second scraper 19 are fixed between the inner walls of both sides of the support frame 1. The first scraper 18 and the second scraper 19 respectively contact the surfaces of the first filter belt 2 and the second filter belt 3 for cleaning the sludge on the surfaces of the first filter belt 2 and the second filter belt 3. A first collection box 10 is fixed between the inner walls of both sides of the support frame 1. Two first conveying pipes 12 are fixed between the inner walls of both sides of the first collection box 10. Multiple first nozzles 13 are fixedly connected to the two first conveying pipes 12. A first rotating rod is rotatably connected between the inner walls of the two sides of the collection box 10. A first cleaning brush 16 is fixed to the outer wall of the first rotating rod to clean the surface of the first filter belt 2. The first cleaning brush 16 is located between the upper and lower first conveying pipes 12. A second collection box 11 is fixed between the inner walls of the two sides of the support frame 1. Two second conveying pipes 14 are fixed between the inner walls of the two sides of the second collection box 11.

A second rotating rod is rotatably connected between the inner walls of the two sides of the second collection box 11. A second cleaning brush 17 is fixed to the outer wall of the second rotating rod to clean the surface of the second filter belt 3. The second cleaning brush 17 is located between the left and right second conveying pipes 14.

[0016] It should be noted that the sludge on the surface of the first filter belt 2 and the second filter belt 3 is scraped off by the first scraper 18 and the second scraper 19. Then, the first filter belt 2 is flushed by the first nozzle 13 on the first first conveying pipe 12, and the sludge in the pores of the first filter belt 2 is cleaned by the first cleaning brush 16. Then, it is flushed by the first nozzle 13 on the second first conveying pipe 12. The second filter belt 3 is flushed by the second nozzle 15 on the first second conveying pipe 14, and the sludge in the pores of the second filter belt 3 is cleaned by the second cleaning brush 17. Then, it is flushed by the second nozzle 15 on the second second conveying pipe 14. This avoids the pores of the first filter belt 2 and the second filter belt 3 from being blocked, reducing the sludge dewatering efficiency, affecting the stability of the filtration effect, and increasing the frequency and cost of equipment maintenance. Both the first conveying pipe 12 and the second conveying pipe 14 are connected to water pipes, and the water pipes are connected to water pumps. Water is delivered to the first conveying pipe 12 and the second conveying pipe 14 by the water pumps.

The first filter belt 2 and the second filter belt 3 are both disposed on the surface of the first pressure roller 5 and the plurality of second pressure rollers 6, for dewatering sludge.

[0020] It should be noted that both the first feeding roller 4 and the third feeding roller 8 are driven by a conveyor motor to rotate, thereby causing the first filter belt 2 and the second filter belt 3 to move. The sludge between the first filter belt 2 and the second filter belt 3 is dewatered by the first pressure roller 5 and multiple second pressure rollers 6 respectively.

[0021] like Figure 3 As shown, the bottom end of the first collection box 10 is fixedly connected to the first drain pipe, and the bottom end of the second collection box 11 is fixedly connected to the second drain pipe. Valves are installed on both the first and second drain pipes. A conveying frame 25 is fixed between the inner walls of both sides of the support frame 1. The conveying frame 25 is located below the first pressure roller 5 and multiple second pressure rollers 6 and is used to convey filtered sewage.

[0022] It should be noted that the first collection box 10 and the second collection box 11 collect the water that falls during cleaning. The water is then discharged and treated through the first drain pipe and the second drain pipe. The conveyor frame 25 is set at an angle to facilitate the discharge of sewage.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
