Since the filter screen 62 is set at an angle, the leachate can be filtered with the assistance of each filter screen 62. The filter screen 62 is set at an angle, and the filtered impurities can be discharged to the discharge hopper 8 through the inclined filter screen 62. The material can be discharged into the interior of the collection frame 23 through the discharge hopper 8. If the collection frame 23 needs to be disassembled and replaced, it can be removed by The slide plate 61 inside the slide groove 21 is pulled out, and then the collection frame 23 can be quickly replaced, which is convenient for taking out the filtered impurities, so that the device as a whole does not need to frequently disassemble and assemble the filter screen 62 during use, and can filter the leachate for a long time, which can improve the use efficiency of the device as a whole during use. If the filter screen 62 needs to be repaired and replaced, it is only necessary to loosen the bolts 66 on the outside of the fixing plate 64, and then pull the bridge handrail 65 out from the inside of the inner slide rail 5, so that the filter screen 62 can be quickly replaced by the device as a whole, which can improve the overall convenience of use of the device;

[0049] By setting the cleaning mechanism 7, during the use of the device, during the filtering period, the drive motor 72 can be started to run, and the drive motor 72 can be used to drive the screw rod 73 to rotate. The rotation of the screw rod 73 can drive the slider 74 to slide on the inner side of the side rail 71. The slider 74 slides on the inner side of the side rail 71, which can assist in adjusting the driving mounting frame 751 to move horizontally inside the filter box 4. At this time, the vertical plate at the end of the limit spring 752 can be pushed by the mounting frame 751 to fit the top of the filter screen 62 for brushing, which can achieve a better brushing and cleaning effect and avoid the clogging of the top of the filter screen 62. In this process, the telescopic elastic force of the limit spring 752 can be set to enable the brush plate 753 to stably contact the top of the filter screen 62, which can improve its overall brushing and cleaning effect. The support rod 754 can be set to assist in supporting and reinforcing the brush plate 753, so that the brush plate 753 can clean the filter screen 62 more stably, which can improve the stability of the overall device during the filtering period.
