[0022] Specifically, the surface of the ventilation mesh plate 3 can be cleaned by using the sliding structure 4 and the cleaning structure 5, thereby preventing a large amount of dust from adhering to the surface of the ventilation mesh plate 3.

[0023] Furthermore, the cleaning structure 5 can be pulled to move along the sliding structure 4, and the surface of the ventilation mesh plate 3 can then be cleaned through the cleaning structure 5.

The cleaning structure 5 includes a frame 501, a mounting hole 502, and a cleaning brush 503. The frame 501 is disposed between the two sliding blocks 403. The mounting hole 502 is opened on the surface of the frame 501. The cleaning brush 503 is snapped into the interior of the mounting hole 502, and the cleaning brush 503 is connected to the ventilation mesh plate 3. The surfaces of the plates 3 are in contact with each other. A connecting component 6 is provided on the front side of the frame 501 and the sliding block 403. The frame 501 and the sliding block 403 are assembled through the connecting component 6. The connecting component 6 includes two vertical plates 601, a through hole 602, a positioning pin 603 and a spring 604. The two vertical plates 601 are respectively fixedly connected to the front side of the frame 501 and the front side of the sliding block 403. The through hole 602 is opened on the surface of the two vertical plates 601 and corresponds to each other. The positioning pin 603 is inserted between the two vertical plates 601 and extends out. The spring 604 is sleeved on the surface of the positioning pin 603. One end of the spring 604 is fixedly connected to the surface of the left vertical plate 601, and the other end of the spring 604 is fixedly connected to the surface of the positioning pin 603.

[0025] Specifically, the sliding structure 4 can be used to provide the movement trajectory of the cleaning structure 5, thereby restricting the movement of the cleaning structure 5 and enabling it to clean the ventilation mesh 3.

[0026] Furthermore, the cleaning brush 503 is assembled through the mounting holes 502 on the surface of the frame 501, and then the frame 501 is placed between the two sliding blocks 403. The assembly of the frame 501 and the sliding blocks 403 is then completed by passing the positioning pin 603 through the two vertical plates 601.

[0027] In embodiment 3, the third embodiment of this utility model, three snap-fit ​​components 7 are equidistantly arranged on the surface of the frame 501, and the snap-fit ​​components 7 are in contact with the surface of the cleaning brush 503. The snap-fit ​​components 7 include a positioning frame 701, a double-ended screw 702, a knob 703, two lifting plates 704, two inserts 705, and two limiting rods 706. The positioning frame 701 is sleeved on the outer surface of the frame 501, the double-ended screw 702 is rotatably connected to the inside of the positioning frame 701, and the knob 703 is rotatably connected to the positioning frame 701. The top of the positioning frame 701 and the bottom of the knob 703 are fixedly connected to the top of the double-ended screw 702. Two lifting plates 704 are threadedly connected to both sides of the surface of the double-ended screw 702.

Two limiting rods 706 are fixedly connected to both sides inside the positioning frame 701. The lifting plates 704 are slidably connected to the surface of the limiting rods 706.

[0028] Specifically, the stability of the cleaning brush 503 after assembly with the frame 501 can be improved by using the snap-fit ​​component 7, thereby preventing the cleaning brush 503 from falling off during movement.

[0029] Furthermore, by placing the positioning frame 701 outside the frame 501, the knob 703 can be rotated. The rotation of the knob 703 can drive the double-headed screw 702 to rotate, which in turn can drive the two threaded lifting plates 704 to move. When the lifting plates 704 move, they can drive the insert pin 705 to move, and then the assembled cleaning brush 503 can be clamped by the insert pin 705.

[0030] Working principle: The cleaning brush 503 is assembled through the mounting holes 502 on the surface of the frame 501. Then, the frame 501 is placed between two sliding blocks 403. The frame 501 and the sliding blocks 403 are assembled by passing the positioning pin 603 through the two vertical plates 601. The positioning frame 701 is placed outside the frame 501, and the knob 703 can be rotated. The rotation of the knob 703 drives the double-headed screw 702 to rotate, which in turn drives the two threaded lifting plates 704 to move. When the lifting plates 704 move, they can drive the insert pin 705 to move, and the assembled cleaning brush 503 can be clamped by the insert pin 705.

[0031] In summary, by using the base 1, sludge dryer 2, ventilation mesh 3, sliding structure 4, cleaning structure 5, connecting component 6, and snap-fit ​​component 7 in combination, the problem of the ventilation mesh in the heat pump coupled heating device of the sludge drying box being lacking an effective cleaning structure, which makes the mesh surface prone to dust and sludge adhesion, affecting the ventilation effect and drying efficiency, is solved.
