Description

Technical Field

[0001] The invention relates to the technical field of bag filters, and more specifically to a garbage leachate filtering device which is easy to clean. Background Art

[0002] Bag filter is a multi-purpose filtering equipment, in which the filter bag is supported by a metal mesh basket. The liquid flows in from the inlet, is filtered by the filter bag and flows out from the outlet. Impurities are intercepted in the filter bag. After replacing the filter bag, it can continue to be used and cleaned.

[0003] The cover of the existing bag filter is fixed by multiple screws and a pressing block. Although the threaded connection between the screw and the pressing block has a high connection strength, the screw is usually long, which results in the pressing block having to be rotated many times during disassembly and assembly, making the cover difficult to disassemble and assemble.

[0004] Therefore, it is necessary to provide a kind of landfill leachate filtering equipment that is easy to clean to solve the above problems. Utility Model Content

[0005] Based on the above-mentioned problems existing in the prior art, the purpose of the embodiments of the present application is to provide a landfill leachate filtering device that is easy to clean and achieves the effect of convenient disassembly and assembly.

[0006] The technical solution adopted by the present application to solve its technical problems is: a garbage leachate filtering device that is easy to clean, comprising a tank body with an opening at the upper end, the upper end of the tank body being covered with a cover plate, the upper edge of the cover plate being recessed to form a card slot, a plurality of groups of support plates are fixed to the upper edge of the tank body, each group of the support plates comprises two support plates, a rotating shaft is rotatably connected between each group of the support plates, a sleeve is fixed in the middle of the rotating shaft, a sleeve hole is provided on the inner side of the sleeve, a sliding rod adapted thereto is provided on the inner side of the sleeve hole, a screw is fixed to the upper end of the sliding rod, a sliding block is sleeved on the screw, a pressure block is threadedly connected to the upper end of the screw, the sliding block is located on the lower side of the pressure block, a card block corresponding to the card slot is fixed on one side of the sliding block, and the sliding rod is suitable for moving in the sleeve hole.

[0007] A screw is arranged at the lower side of the sleeve, and one end of the screw is threadedly connected with the lower end of the sliding rod.

[0008] The cross section of the sleeve hole is non-circular.

[0009] A handle is fixed on the pressing block.

[0010] A limiting rod is fixed to one end of the screw rod away from the sliding rod, and a limiting block is fixed to one end of the limiting rod away from the screw rod.

[0011] The beneficial effects of the utility model are as follows: the length of the screw extending out of the sleeve is adjusted by moving the sliding rod in the sleeve hole. When the length of the screw extending out of the sleeve becomes shorter, the number of revolutions required to remove the pressing block from the screw is reduced, thereby facilitating the removal of the pressing block; when the length of the screw extending out of the sleeve becomes longer, the connection strength between the pressing block and the screw can be increased, thereby reducing the number of revolutions required to remove the pressing block from the screw while ensuring the connection strength between the pressing block and the screw, thereby facilitating the disassembly between the tank body and the cover plate, and facilitating the removal of the filter bag from the tank body for cleaning.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0021] like Figure 1-2As shown, the present application provides a leachate filtering device that is easy to clean, including a tank body 1 with an upper opening, the upper end of the tank body 1 is covered with a cover plate 11, the upper edge of the cover plate 11 is recessed to form a slot 12, and a plurality of groups of support plates 13 are fixed to the upper edge of the tank body 1, and each group of support plates 13 includes two support plates 13.

[0022] A rotating shaft 2 is rotatably connected between each set of support plates 13, a sleeve 21 is fixed in the middle of the rotating shaft 2, and a sleeve hole 22 is arranged inside the sleeve 21. The cross section of the sleeve hole 22 is non-circular, and a sliding rod 23 adapted thereto is arranged inside the sleeve hole 22. A screw 24 is arranged at the lower side of the sleeve 21, and one end of the screw 24 is threadedly connected to the lower end of the sliding rod 23.

[0023] A screw rod 25 is fixed to the upper end of the slide rod 23 , a slider 26 is sleeved on the screw rod 25 , a pressing block 27 is threadedly connected to the upper end of the screw rod 25 , and the slider 26 is located at the lower side of the pressing block 27 .

[0024] A handle 271 is fixed on the pressing block 27 , and a clamping block 261 corresponding to the clamping slot 12 is fixed on one side of the sliding block 26 .

[0025] A limiting rod 28 is fixed to one end of the screw rod 25 away from the slide rod 23 , and a limiting block 281 is fixed to one end of the limiting rod 28 away from the screw rod 25 .

[0026] The head of the screw 24 is used to abut against the lower end of the sleeve 21. When the cover plate 11 covers the upper end of the tank body 1, the pressing block 27 is rotated by the handle 271, so that the pressing block 27 is lowered by the threaded connection between the screw rod 25 and the pressing block 27, and the pressing block 27 then presses the slider 26 to lower. After the clamping block 261 is inserted into the clamping groove 12, the pressing block 27 is tightened, and the trend between the head of the screw 24 and the clamping block 261 approaching each other will drive the cover plate 11 to cover the opening of the tank body 1. In this way, the tank body 1 is sealed so that filtering can be performed in the tank body 1.

[0027] After the filtration is completed, the cover plate 11 and the tank body 1 can be loosened by loosening the pressing block 27, so that the staff can take out the filter bag in the tank body 1 for cleaning.

[0028] By rotating the screw 24 and utilizing the threaded connection between the screw 24 and the slide bar 23 , the slide bar 23 can be driven to slide in the sleeve hole 22 , thereby adjusting the length of the screw rod 25 extending out of the sleeve 21 .

[0029] When the length of the screw 25 extending out of the sleeve 21 becomes shorter, the number of revolutions required for the staff to remove the pressing block 27 from the screw 25 decreases, thereby facilitating the removal of the pressing block 27, allowing for quick disassembly and assembly between the tank body 1 and the cover plate 11, and reducing the trouble of removing the filter bag.

[0030] When the length of the screw 25 extending out of the sleeve 21 becomes longer, although the number of turns required for the staff to remove the pressure block 27 from the screw 25 increases, the connection strength between the pressure block 27 and the screw 25 can be increased, thereby avoiding insufficient connection strength between the pressure block 27 and the screw 25, and preventing the internal pressure inside the tank body 1 from causing damage to the pressure block 27 and the screw 25 during filtration.

[0031] In summary, the staff can reduce the number of rotations required to remove the pressure block 27 from the screw 25 according to the working situation while ensuring the connection strength between the pressure block 27 and the screw 25, thereby facilitating the disassembly between the tank body 1 and the cover plate 11, and facilitating the removal of the filter bag from the tank body 1 for cleaning.

[0032] Since the cross section of the sleeve hole 22 is non-circular, the sleeve hole 22 and the slide bar 23 can prevent the slide bar 23 from rotating.

[0033] After the screw rod 25 and the pressing block 27 are separated, the screw rod 25 and the limiting block 281 are used to limit the position of the pressing block 27 to prevent the pressing block 27 from falling.
