Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, specifically a sludge solid-liquid separation and dewatering treatment device that facilitates material discharge. Background Technology

[0002] Currently, there are various types of sludge treatment equipment, including sludge solid-liquid separation and dewatering treatment devices. These devices come in various types, including fully automatic chamber filter presses. These presses use a hydraulic system to provide strong pressure, which compresses sludge and other materials in the filter chamber. Water passes through the filter cloth and is discharged, while solid particles are retained in the filter chamber, thus achieving solid-liquid separation.

[0003] The existing sludge solid-liquid separation and dewatering treatment equipment still has the following problems when in use: When using its fully automatic chamber filter press, the built-in filter cloth often needs to be disassembled and cleaned after use. The frequent disassembly and cleaning is inconvenient and can easily affect the overall efficiency of sludge solid-liquid separation and dewatering treatment. Utility Model Content

A pressurizing mechanism is provided at one end of the filter box 17, and a feed connector 111 is provided in the middle of the other end of the filter box 17. A filter cloth is provided inside the filter box 17, and multiple filter cloths are arranged horizontally and equidistantly below the front end of the filter box 17. The drain pipe 18 and filter box 17 are equipped with a backwashing mechanism.

[0023] An outer protective mechanism 2 is provided on the outside of the solid-liquid separation mechanism 1. The outer protective mechanism 2 includes a connecting frame 21 fixedly connected to the top of the first fixed frame 11 and the second fixed frame 12.

The solid-liquid separation mechanism 1 is equipped with an outer protective mechanism 2. That is, the top of the solid-liquid separation mechanism 1 is provided with a frame, the top of the frame is fixedly connected with a protective top, and the front and rear ends of the frame are provided with protective side covers 24. These can work together with the protective top to provide good protection for the outside of the solid-liquid separation mechanism 1 and prevent the solid-liquid separation mechanism 1 from being damaged by impacts from external objects.

[0024] The bottom ends of the first fixed frame 11 and the second fixed frame 12 are each fixedly connected to a support frame 13. The pressurizing mechanism includes a pressurizing device 15 fixedly connected to one end of one side of the support frame 13. A pressurizing pipe 16 is connected to the pressurizing port of the pressurizing device 15. The pressurizing pipe 16 is connected to a corresponding pressure interface at one end of the filter box 17. A strong pressure is provided by the hydraulic system, so that the sludge and other materials are squeezed in the filter chamber of the filter box 17. Water passes through the filter cloth and is discharged, while solid particles are trapped in the filter chamber, thereby realizing solid-liquid separation.

[0025] Two support frames 13 are fixedly connected to the same collection hopper 19 at their front ends. The collection hopper 19 is located below multiple drain pipes 18. The bottom of the collection hopper 19 has an opening on the other side, and a discharge pipe 110 is fixedly installed at the opening.

Water discharged from multiple drain pipes 18 of the filter box 17 can be collected through the collection hopper 19.

[0026] The working principle of this utility model is as follows: Sludge to be separated and dehydrated is added to the filter box 17 via the feed connector 111. A pressurizing pipe 16 is connected to the pressurizing port of the pressurizing device 15, and the pressurizing pipe 16 is connected to a corresponding pressure interface at one end of the filter box 17. A strong pressure is provided by the hydraulic system, causing the sludge and other materials to be squeezed within the filter chamber of the filter box 17. Water passes through the filter cloth and is discharged, while solid particles are retained within the filter chamber, thus achieving solid-liquid separation. Water discharged from multiple drain pipes 18 of the filter box 17 can be collected via the collection hopper 19. Because the entire system is equipped with a self-cleaning structure for sludge solid-liquid separation and dehydration, i.e., a backwashing mechanism is provided, it is matched with a backwash connector 112 in the filter box 17. This connector can be connected to a valve, and through the valve, a high-pressure water delivery pipeline is connected. The water flow direction is opposite to the filtration direction of the filter cloth, which can wash away impurities on the surface of the filter cloth and discharge them from the filter box 17. This achieves efficient and rapid cleaning of the filter cloth inside the filter box 17 without the need for manual disassembly and cleaning, which is quite convenient.
