At the same time, the baffle 20 can block water, preventing atomized water from spraying onto the dust sensor 21 when the water pressure is too high. Then, the nut 18 is rotated to make the nut 18 contact the threaded tube 19, thereby fixing the position of the threaded tube 19 and preventing it from loosening and moving.

[0043] The blocking mechanism includes a baffle 30, which is rotatably connected to one side of the frame 1. A plurality of evenly distributed arc-shaped grooves 28 are provided on one side of the baffle 30, and an installation groove 29 is provided on one side of the frame 1.

When atomization dust removal is required, the baffle 30 is rotated to disengage the baffle 30 from the rotating block 11. At this time, the rotating block 11 can rotate. After the rotating block 11 rotates a certain angle, the baffle 30 is rotated again to block the rotating block 11. At this time, the rotating block 11 is blocked by the baffle 30, thereby fixing the position of the rotating block 11.

[0044] The connecting component includes a connecting pipe 15, which is slidably connected within the water channel 16. An insertion hole 32 is provided on the other side of the frame 1, and the insertion hole 32 is connected to the water channel 16.

A U-shaped guide groove 25 is provided on the inner wall of one side of the slide 23. A flexible plate 24 is welded to one side of the slide tube 6. The flexible plate 24 can be made of copper, aluminum, or steel, preferably steel. The other end of the flexible plate 24 is fixed to the connecting pipe 15. When two devices are connected, one side of one device will press the slide tube 6 into the slide 23, which will cause the flexible plate 24 to move. The flexible plate 24 will then cause the connecting pipe 15 to move, eliminating the need for manual adjustment of the position of the connecting pipe 15 and further improving installation efficiency.

[0046] The pipe connection assembly includes a Velcro strap 38, which is fixed to the inner wall of one side of the frame 1 by a buckle. The Velcro strap 38 is tied to a corrugated pipe 39. Both ends of the corrugated pipe 39 are fixed with connectors 37 by clamps, and the connectors 37 can be inserted into the water channel 16. When it is necessary to bend and connect two devices, the corrugated pipe 39 is removed from the Velcro strap 38, and then one connector 37 is tightened into the water channel 16, and the other connector 37 is screwed into the water channel 16 of the other device, thereby connecting the water channels 16 of the two devices. At the same time, the corrugated pipe 39 can be bent.

[0047] The support assembly includes two guide frames 4, both of which are bolted to the inner walls of both sides of the frame 1. A slide 3 is slidably connected to the outer circumference of each guide frame 4. Two connecting rods 43 are rotatably connected to the bottom of each slide 3 via a shaft. A support rod 44 is rotatably connected to the other end of each connecting rod 43. Two fixing rods 45 are bolted to the top of each support rod 44. At least one counterweight 46 is fitted around the outer circumference of each fixing rod 45. The counterweight 46 increases the weight of the support rod 44, shifting the center of gravity of the device rearward and preventing tipping. The two connecting rods 43... The limit rod 47 is fixed between the frame 1 and the slide 3. Threaded holes are opened on both sides of the slide 3. The fixed screws 42 are connected to the threaded holes and are in contact with the frame 1. The handle 5 is fixed to one side of the slide 3 by bolts. When the equipment needs to be supported, the fixed screws 42 are rotated to disengage from the frame 1. Then, the slide 3 is moved downward by the handle 5 and the support rod 44 is pulled backward. The support rod 44, the frame 1 and the connecting rod 43 form a triangle, thereby forming a stable structure and enhancing the stability of the equipment support.

[0048] The fixing assembly includes at least one fixing plate 33, which is fixed to one side of the frame 1 by bolts. A rotating plate 34 is rotatably connected to one side of the fixing plate 33 via a shaft. Two connecting plates 35 are rotatably connected to one side of the rotating plate 34. The other end of each connecting plate 35 is provided with a slot 36. The same number of T-shaped brackets 41 as the connecting plates 35 are fixed to one side of the frame 1 by bolts, and the T-shaped brackets 41 can be inserted into the slots 36. A rubber pad 40 is adhered to the inner wall of one side of the T-shaped bracket 41. When the two devices are connected, the rotating plate 34 is rotated at a certain angle, and then the connecting plate 35 is rotated so that the slots 36 engage the T-shaped brackets 41. At the same time, the connecting plate 35 will squeeze the rubber pad 40, causing the rubber pad 40 to deform and thus clamp the connecting plate 35, preventing the connecting plate 35 from easily falling off, thereby connecting the two devices.

[0049] The working principle of this embodiment is as follows: When using it,

[0050] S1: Multiple devices are combined to form a enclosure. When two devices are horizontally connected, one side of one device will squeeze the slide pipe 6 into the slide groove 23. The slide pipe 6 will drive the flexible plate 24 to move. The flexible plate 24 will drive the connecting pipe 15 to move, so that the connecting pipe 15 is inserted into the insertion hole 32, thereby connecting the waterways 16 of the two devices.

[0051] S2: When two devices need to be bent and connected, remove the corrugated pipe 39 from the Velcro strap 38, then tighten one of the connectors 37 into the water channel 16, and screw the other connector 37 into the water channel 16 of the other device, thereby connecting the water channels 16 of the two devices.

[0052] S3: Rotate the threaded tube 19 to move the dust sensor 21 away from the liquid separator 12, thereby enabling the detection of dust at different heights. At the same time, the baffle 20 can block water and prevent atomized water from spraying onto the dust sensor 21 when the water pressure is too high.

[0053] S4: Rotate the baffle 30 to disengage the baffle 30 from the rotating block 11. At this time, the rotating block 11 can rotate. Rotating the rotating block 11 will drive the liquid distribution pipe 12 to rotate, so that the atomizing nozzle 14 will rotate to the top of the frame 1. Continue to rotate the baffle 30 so that the baffle 30 blocks the rotating block 11 again. At this time, the rotating block 11 is blocked by the baffle 30, thereby fixing the position of the rotating block 11 and fixing the position of the atomizing nozzle 14.

[0054] S5: Rotate the rotating plate 34 at a certain angle, and then rotate the connecting plate 35 to make the slot 36 hold the T-shaped bracket 41. At the same time, the connecting plate 35 will squeeze the rubber pad 40, causing the rubber pad 40 to deform and thus clamp the connecting plate 35, so that the connecting plate 35 will not easily fall off, thereby connecting the two devices.

[0055] S6; Rotate the fixing screw 42 to disengage it from the frame 1, then move the slide 3 downwards by using the handle 5, and pull the support rod 44 backwards a certain distance. Then reverse the fixing screw 42 to form a triangle between the support rod 44, the frame 1, and the connecting rod 43. Use bolts to fix the support rod 44 to the ground, thereby completing the support of the frame 1.

[0056] S7: Connect one side of the enclosure to an external water source so that when the dust sensor 21 detects the dust concentration in the atmosphere and the electric control valve 13 needs to be opened, it transmits a signal to the processor 9. The processor 9 opens the switch of the electric control valve 13 according to the signal, thereby achieving precise control of dust reduction.

[0057] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
