Description

Technical Field

[0001] The present application relates to the technical field of cloth cleaning, and in particular to a filter cloth cleaning device. Background Art

[0002] With the increasing demands of the environmental protection industry, both municipal sewage sludge and leachate sludge have a moisture content of 80%. This high moisture content prevents direct incineration in incinerators and cannot be directly utilized as a resource. Sludge drying not only reduces hazardous waste but also has a wide range of applications, including but not limited to biofiberboard manufacturing, brick making, organic fertilizer, metal recycling, building materials manufacturing, biogas production from sludge digestion, sludge composting, sludge fuel, and power generation. Currently, commonly used equipment uses a hydraulic press to remove moisture. During the pressing process, a large amount of sludge residue will enter the filter cloth surface. If not cleaned promptly, it will significantly reduce the filter cloth's filtration performance, thus affecting the function of the entire process.

[0003] The most common sludge drying equipment currently available on the market uses a filter press + drying process. For projects with less stringent moisture requirements, a filter press and filter cloth conveyor are often sufficient to meet the requirements. Regardless of the process, filter cloth is used. The sludge filter cloth serves as a carrier for wet sludge and is typically dehydrated by filter press under high pressure using a hydraulic device. After dehydration, the dry sludge is transported along with the filter cloth to the dry sludge bin, and the cycle continues. However, due to sludge adhesion on the filter cloth, the filter pores are blocked, significantly reducing filtration performance. Regular acid and alkali soaking and cleaning are required to restore filtration performance.

[0004] At present, filter cloths are mostly cleaned manually or automatically by fixed brushes. The brush cleaning structure is complex, and the brush bristles are easily deformed. The service life is short and the replacement is frequent. The brush cleaning is often limited to the surface of the filter cloth. The scale inside the filter pores is difficult to clean out, and the brush has a destructive effect on the filter cloth, which affects the service life of the filter cloth. Utility Model Content

[0034] The unwinding roller 2 and the winding roller 3 are both rotatably connected to the top of the cleaning tank 1. The cleaning tank 1 is connected to a driving source for driving the unwinding roller 2 and the winding roller 3 to rotate. Two intermediate rollers 4 are provided. The two intermediate rollers 4 are both located between the unwinding roller 2 and the winding roller 3. The intermediate roller 4 is located in the cleaning tank 1. Two mounting frames for respectively mounting the two intermediate rollers 4 are provided in the cleaning tank 1. The intermediate roller 4 is rotatably connected to the mounting frame.

[0035] The control assembly 5 is used to adjust the relative positions of the two intermediate rollers 4 so that the filter cloth between the intermediate rollers 4 is arranged horizontally or inclined.

[0036] The control assembly 5 includes an adjustment plate 53, a gear 51, and a rack 52. The gear 51 is rotatably connected to the outer wall of the cleaning tank 1. The cleaning tank is provided with a drive source for driving the gear 51 to rotate. Two racks 52 are located on either side of the gear 51 and mesh with the gear 51. The racks 52 are vertically slidably connected to the cleaning tank 1. The cleaning tank 1 is provided with a sliding opening. The adjustment plate 53 is located in the cleaning tank 1 and is connected to both ends of the intermediate roller 4. The adjustment plate 53 on one intermediate roller 4 is connected to a rack 52 via a connecting block. The connecting block is located in the sliding opening and is vertically slidably connected to the cleaning tank 1. In other embodiments, multiple meshing gears 51 may be provided between the two racks 52, and the number of gears 51 is an odd number.

[0037] It should be noted that the intermediate roller 4 is connected to the adjustment plate 53 through the mounting seat 54, the mounting seat 54 is rotatably connected to the intermediate roller 4, an adjustment groove 55 is provided on the adjustment plate 53 in the horizontal direction, the mounting seat 54 is embedded in the adjustment groove 55, and a spring 56 is provided between the mounting seat 54 and the two end faces of the adjustment groove 55, and the mounting seat 54 slides in the horizontal direction along the adjustment groove 55 and the adjustment plate 53.

[0038] The cleaning assembly 6 includes multiple water pipes 61, which are respectively arranged on the upper and lower sides of the filter cloth between the two middle rollers 4. There are multiple water pipes 61 on each side of the filter cloth, and the multiple water pipes 61 are arranged parallel to each other. The water pipes 61 on the same side of the filter cloth are connected together by a connecting pipe 62 to form a cleaning pipe group 63. The length direction of the water pipe 61 is arranged along the conveying direction of the filter cloth between the middle rollers 4. A water spray port is provided on the side wall of the water pipe 61 facing the filter cloth, and a high-pressure nozzle is provided at the water spray port. The nozzle is in a constricted form, which can increase local pressure and can thoroughly remove sludge between the pores of the filter cloth. Automatic cleaning can be set throughout the process, and the cleaning time is adjustable.

[0039] It should be noted that the cleaning pipe group 63 is connected between the two racks 52 through the mounting plate 57. Two slide grooves are provided on the mounting plate 57. When the water pipe 61 is set in the horizontal direction, the length direction of the slide groove is set in the horizontal direction. Both ends of the mounting plate 57 are connected to connecting rods 59 that slide along the length direction of the slide groove. The two connecting rods 59 are hinged to the two racks 52 at one end away from the mounting plate 57.

[0040] In this embodiment, teeth are provided on the connecting rod 59 , and a control wheel 58 is rotatably connected to the mounting plate 57 . The two connecting rods 59 are located on both sides of the control wheel 58 and mesh with the control wheel 58 .

[0042] The implementation principles of this application are:

[0043] The filter cloth is transported through the unwinding roller 2, the intermediate roller 4, and the winding roller 3. The two intermediate rollers 4 tension the filter cloth. The high-pressure nozzle on the water pipe 61 cleans the filter cloth. The layout of multiple parallel, upper and lower layers of flushing pipes improves cleaning efficiency.

[0044] Furthermore, by rotating gear 51, racks 52 on either side of gear 51 simultaneously move upward and downward, tilting the filter cloth between the two intermediate rollers 4. At the same time, springs 56 on either side of mounting base 54 compensate for the horizontal position of intermediate rollers 4, maintaining a constant length of filter cloth between unwinding roller 2 and rewinding roller 3 and keeping the filter cloth taut on intermediate rollers 4. Spraying water on the filter cloth while it is tilted not only effectively cleans scale and sludge from its surface but also clears sludge between its pores. This also reduces water carryover, preventing incomplete brush cleaning and damage to the filter cloth. This overall extends the service life of the filter cloth and improves the dehydration stability of the entire system.

[0045] The cleaning pipe group 63 can also rotate, and the connecting rod 59 moves under the drive of the rack 52, the mounting plate 57 rotates, and the connecting rod 59 slides along the slide groove relative to the mounting plate 57, so that the water pipe 61 on the mounting plate 57 also rotates. At this time, the water pipe 61 remains parallel to the filter cloth.

[0046] Based on the above-described preferred embodiments of the present invention, and in accordance with the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
