The lower edge of scraper 300 is flush with first residue discharge port 101, and the projection of scraper 300 in vertical direction is located on the moving path of first residue discharge door 200.

[0027] The technical scheme of the present application is applied, the filter residue hopper 100 has the relative setting of the draining state and the residue discharging state, when the first residue discharge door 200 blocks the first residue discharge port 101, the filter residue hopper 100 is in the draining state, and the water in the waste residue can be discharged through the first filter plate 210 and the first drainage port 201 to reduce the moisture content of the waste residue; when the first residue discharge door 200 opens the first residue discharge port 101, the filter residue hopper 100 switches to the residue discharging state, and the waste residue in the filter residue hopper 100 after draining can be loaded into a vehicle through the first residue discharge port 101 for transfer. By setting the scraper 300 on the moving path of the first residue discharge door 200, when the first residue discharge door 200 switches between the draining state and the residue discharging state along the linear motion, the scraper 300 can clean the first filter plate 210, remove the waste residue stuck on the first filter plate 210, reduce the dirt blockage of the first filter plate 210, reduce the number of disassembly and assembly of the first filter plate 210, reduce the maintenance frequency of the equipment, and ensure the operation efficiency of the overall draining system.

[0028] Specifically, the material of the scraper 300 can be polyurethane to reduce the wear of the scraper 300.

[0029] Further, the draining device further comprises a support frame 400, the support frame 400 is fixedly arranged on the filter residue hopper 100, the scraper 300 is fixedly arranged on the support frame 400, and the first residue discharge door 200 and the support frame 400 are provided with a sliding part, and the first residue discharge door 200 is slidably connected with the support frame 400. In the present application, by setting the first residue discharge door 200 in the form of linear motion, the first residue discharge door 200 can be switched between the draining state and the residue discharging state, and by setting the sliding part, the sliding friction between the support frame 400 and the first residue discharge door 200 can be reduced, and the opening and closing of the first residue discharge door 200 are facilitated.

[0030] In an embodiment of the present application, the outer periphery of the first filter plate 210 protrudes the outer periphery of the first slag door 200, the support frame 400 has two side beams arranged oppositely, the side beams extend along the moving direction of the first slag door 200, the sliding member includes rollers 410, and a plurality of rollers 410 are arranged on the side walls of the two side beams arranged oppositely, and the rollers 410 are used to support the first filter plate 210. Through the above arrangement, the first filter plate 210 can move relative to the slag filter hopper 100 through the rollers 410, and by arranging the rollers 410 below the first filter plate 210, the accumulation of waste slag at the contact position of the rollers 410 and the first filter plate 210 can be reduced, and the normal sliding cooperation between the rollers 410 and the first filter plate 210 can be ensured.

[0031] As the operation time of the slag filter hopper 100 increases, the rollers 410 will deform, which will cause the gap between the first slag door 200 and the first slag port 101 to wear and increase, and a large amount of slag water will flow out through the gap, which will pollute the factory environment on the one hand and reduce the draining effect of the device on the other hand. In the embodiment, the height adjusting member is arranged between the support frame 400 and the slag filter hopper 100, which can adjust the position of the first slag door 200 relative to the first slag port 101 in the height direction, and then adjust the gap between the first slag door 200 and the first slag port 101, so that the first slag door 200 and the first slag port 101 are kept within a smaller range, and a large amount of slag water is prevented from flowing out.

[0032] Specifically, the height adjusting member includes a tensioning bolt 420, and the connecting frame 110 and the support frame 400 are connected through the tensioning bolt 420. Through the above arrangement, the distance between the first slag door 200 and the connecting frame 110 can be adjusted through the tensioning bolt 420, and then the gap between the first slag door 200 and the first slag port 101 can be adjusted.

[0033] Further, the outer periphery of the first slag port 101 is provided with a sealing baffle, which is used to seal the gap between the first slag port 101 and the first filter plate 210, so as to further seal the first slag port 101 and prevent slag water from flowing out. Specifically, the sealing baffle can be a soft rubber baffle, so that the sealing baffle can adapt to different distances between the first slag door 200 and the first slag port 101.

[0034] Specifically, the first slag discharge gate 200 has a flow guide cavity 202, one end of the flow guide cavity 202 is provided with a first filter plate 210, the other end of the flow guide cavity 202 forms a first drainage port 201, and the flow area of the flow guide cavity 202 gradually decreases in the direction from the first filter plate 210 to the first drainage port 201. In the prior art, the slag discharge gate is usually provided in the form of an inclined flat plate, and the filtered slag water may still contain some fine slag, and the fine slag is easy to deposit in the flat plate-shaped slag discharge gate, thereby affecting the drainage efficiency of the slag discharge gate. In the present application, by arranging the flow guide cavity of the first slag discharge gate 200 to gradually decrease in the direction from the first filter plate 210 to the first drainage port 201, the deposition of fine slag in the flow guide cavity 202 is reduced, the clogging of the first drainage port 201 is reduced, and the slag discharge efficiency of the first slag discharge gate 200 is improved.

The plurality of planar flow guide plates 220 can also facilitate the production and welding of the first slag discharge gate 200.

[0036] Specifically, the side wall of the slag filter bucket 100 is also provided with a plurality of second slag discharge ports, the plurality of second slag discharge ports are annularly and spacedly arranged on the side wall of the slag filter bucket 100, the side wall of the slag filter bucket 100 is also provided with a plurality of second slag discharge gates 500, the second slag discharge gates 500 are hinged to the side wall of the slag filter bucket 100, the plurality of second slag discharge gates 500 are arranged in one-to-one correspondence with the plurality of second slag discharge ports, and a second filter plate is arranged between the second slag discharge gate 500 and the second slag discharge port.

[0037] Further, the second filter plate is detachably arranged on the second slag discharge gate 500. In this way, when the second filter plate needs to be cleaned, the second filter plate that needs to be cleaned can be directly detached, and a second filter plate that is not clogged can be installed. The second filter plate that is relatively clean is used to replace the second filter plate that has been clogged, thereby reducing the maintenance time and improving the cleaning efficiency of the slag filter bucket 100.
