Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0014] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0015] As Figure 1 、 Figure 2 shown, a dust-proof device includes a hopper box 1 and an ash collection box 2 above it. A cylindrical ash outlet 3 is provided at the bottom of the ash collection box 2, and a surrounding water belt 4 is provided in the middle and lower part of the ash outlet 3. The surrounding water belt 4 is connected to a water pump water source through a water pipe; fine hole water outlets 5 are provided on the surrounding water belt 4, and the fine hole water outlets 5 face the hopper box 1.

[0016] Furthermore, a spray overflow water collection tank 6 is provided on the ground around the hopper box 1.

[0017] Furthermore, the surrounding water belt 4 includes a water belt body 41. Adhesive fasteners 42 are respectively provided at the head and tail ends of the water belt body 41. The adhesive fasteners 42 make the surrounding water belt connect end to end and cover the ash outlet 3. The water belt body 41 is a double-layer water bag, and there is a water storage chamber in the middle of the double-layer water bag. The fine hole water outlets 5 are distributed in a matrix on the surface water belt body 41.

[0018] Furthermore, the water belt body 41 is a flat surrounding water belt in one circle.

[0019] The working principle of the present utility model is:

[0020] In combination with the ash discharge port of the dust collector's ash collection box, a circular flat water belt (with fine hole water outlets 5 arranged in two parallel rows with a staggered arrangement) is arranged above the outer wall of the ash discharge port 3 and connected to the valve of the recycled water source in the factory area. The atomization of the water discharged from the fine hole water outlets 5 can be controlled by adjusting the water pressure through the water source valve, forming a "umbrella"-shaped protective film 7 between the ash discharge port 3 and the ash hopper box 1, covering the upper part of the ash hopper box 1, effectively intercepting the ash dust during discharge, avoiding environmental pollution around the site, and ensuring the safety of the on-site working environment. At the same time, in combination with the water mist radiation range of the spray device and the size of the ash hopper box, a spray overflow water collection tank 6 is arranged on the ground around the placement position of the ash hopper box. The collected water can be recycled after treatment, saving water resources.

[0021] Before ash discharge, after placing the ash hopper box 1 below the ash discharge port 3, first open the water source valve of the surrounding water belt 4, thereby turning on the ash discharge port spray device. Through the spraying action, the bottom of the ash hopper box 1 and the inner wall around the ash hopper box 1 are wetted, ensuring that the ash discharged can be well adsorbed on the bottom of the ash hopper box 1 instantly when it falls to the bottom of the ash hopper box 1. The wet inner wall of the ash hopper box 1 adsorbs the secondary dust generated after the ash discharged falls into the ash hopper box to a certain extent.

[0022] During the ash discharge process, the water mist directly above the ash hopper box 1 and the dust intercepted by the water mist fall layer by layer into the ash hopper box 1, covering the surface layer of the ash collected in the ash hopper box 1, increasing the humidity of the ash collected in the ash hopper box 1 (not easily scattered), and reducing the secondary dust generated when the ash is discharged from the ash discharge port 3 and falls into the ash hopper box 1.

[0023] After ash discharge, delay closing the water source valve to ensure that the dust in the ash discharge port of the ash collection box to the inside of the ash hopper box is effectively controlled before closing the spray device.

[0024] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the overall concept of the present invention, several changes and improvements can still be made, and these should also be regarded as the protection scope of the present invention.
