[0045] The dust inlet 2 may be provided with an air inlet fan to facilitate the entry of external dust-laden air into the dust inlet 2; the external dust-laden air enters the filter box 31 in the filter assembly 3 through the dust inlet 2, and is filtered through the filter conveyor belt 32 (this prevents larger particles of dust from easily causing blockage, and is also beneficial to improving the spraying effect); the air then enters the spray water tank 4 for spray dust removal under the action of the spray plate assembly 5 (that is, after the dust-laden air enters the spray water tank 4, the nozzle 52 can spray clean water to spray the dust-laden air); the air after spray dust removal enters the air outlet box 6 and is discharged from the air outlet 7.

[0046] Example 2

[0047] Based on the first embodiment, Figures 1 to 2 、 Figures 4 to 6 As shown, the partition 51 divides the interior of the spray water box 4 into an upper chamber 41 and a lower chamber 42. The filter box 31 is connected to the lower chamber 42 through a horizontally arranged connecting pipe 311. The nozzle 52 is located at the top of the upper chamber 41. The upper chamber 41 and the lower chamber 42 are connected through an air outlet pipe 53.

At this time, the water mist nozzle 522 is started at the same time for spraying (the clean water in the spray box is sprayed out from the water mist nozzle 522), and the air after spraying and dust removal enters the air outlet box 6 from the upper chamber 41, and is then discharged from the air outlet 7.

[0048] A drainage pipe 43 is provided on the bottom surface of the spray water tank 4, and the drainage pipe 43 is connected to the lower chamber 42; a liquid collecting tank 8 is provided at the bottom of the shell 1, and one end of the drainage pipe 43 away from the lower chamber 42 passes through the liquid collecting tank 8; after the clean water sprayed out removes dust from the air, it flows into the lower chamber 42 and flows through the drainage pipe 43 to the liquid collecting tank 8 in the shell 1 for collection.

[0049] The number of the air outlet pipes 53 is the same as the number of the water mist nozzles 522. The air outlet pipes 53 are distributed in an array on the partition 51, and the air outlet pipes 53 vertically penetrate the partition 51. The positions of the air outlet pipes 53 correspond one-to-one with the positions of the water mist nozzles 522, which facilitates one-to-one spraying between the water mist nozzles 522 and the air outlet pipes 53, so that the contact time between the clean water and the dust-laden air is long and the contact area is large, which is beneficial to improving the dust removal effect on the dust-laden air.

[0053] The air intake of dusty air can be adjusted according to the needs of dust removal, that is, each adjusting roller 543 can be rotated or stopped, so that the air storage groove 544 on the outer peripheral wall of the adjusting roller 543 can be rotated and adjusted to different positions to achieve different air intake effects: when the adjusting roller 543 is always kept in a rotating state, the dusty air in the air flow box 541 can enter the air storage groove 544, and when the air storage groove 544 is rotated to a position corresponding to the air outlet groove 542, the dusty air can enter the lower chamber 42 through the air outlet groove 542. When the dust-laden air enters the upper chamber 41 from the air outlet pipe 53, the water mist nozzle 522 can spray clean water mist to spray the dust-laden air (when there is spray water in the air storage groove 544, it can flow out as the adjusting roller 543 rotates and the air storage groove 544 faces the bottom surface of the air flow box 541); at the same time, when the outer peripheral wall of the adjusting roller 543 conflicts with the opening of the air outlet groove 542 and the inner bottom surface of the air flow box 541, the dust-laden air cannot enter the air outlet groove 542.

[0054] Multiple motors for driving the adjustment rollers 543 to rotate can be provided on the outer wall of the air flow box 541, and each adjustment roller 543 is driven by one motor; each motor can be started at the same time to drive all the adjustment rollers 543 to rotate together, at which time the air intake volume is maximized; one or more motors can also be started individually.

[0055] The airflow box 541 (ie, the airflow regulating roller assembly 54 ) can also be removed from the lower chamber 42 , so that the dust-laden air can circulate directly without any flow regulation.

[0056] Example 4

[0057] Based on the first embodiment, Figure 1 、 Figures 3 and 4 The filter conveyor belt 32 is composed of a plurality of filter soft plates 321 connected end to end in sequence. The filter soft plates 321 are a mesh-like structure, and the filter soft plates 321 are movable through the other two opposite side walls of the filter box 31; the distance between the other two opposite side walls of the filter box 31 is adapted to the width of the filter conveyor belt 32, so that when the dust-laden air enters through the dust inlet 2 on the side wall of the filter box 31, it can be filtered under the action of the filter soft plates 321, and then enter the spray water box 4 through the side wall at the opposite end of the dust inlet 2; when the filter soft plates 321 located in the filter box 31 have been used for a period of time, the filter soft plates 321 can be rotated again and the unused filter soft plates 321 can be rotated into the filter box 31, thereby improving the filtering effect of the dust-laden air and avoiding clogging of the filter soft plates 321 (the used filter box 31 can also be cleaned and reused, thereby reducing costs).
