DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Embodiment 1: This embodiment provides a ventilation and dust removal device for coal mine operation, see Figure 1-4 Specifically, it includes a body 1, an air duct 11 is opened in the body 1, a protective net 12 is fixedly provided at one end of the outlet of the air duct 11, a fan 13 is fixedly provided at one end of the air duct outlet 11, a water tank 14 is provided at the bottom of the body 1, a drain pipe 15 is fixedly provided at the bottom of one side of the body 1, a water pump 16 is fixedly provided at the top of the body 1, a connecting pipe 17 is fixedly provided at the bottom of the water pump 16, a right-angle pipe 18 is fixedly provided on one side of the water pump 16, a filter head 19 is fixedly provided at the other end of the right-angle pipe 18, an atomizer 111 is fixedly provided at the other end of the connecting pipe 17, a plurality of atomizing nozzles 112 are fixedly provided at the bottom of the atomizer 111, a slide plate 113 is slidably provided in the body 1, a filter net 114 is fixedly provided in the middle of the slide plate 113, a vertical plate 115 is fixedly provided on one side of the slide plate 113, a pair of fixed frames 116 are provided in the body 1, a drying plate 117 is fixedly provided in the middle of one fixed frame 116, and an activated carbon filter plate 118 is fixedly provided in the middle of the fixed frame 116 at the other end;

[0025] The protective net 12 and the fan 13 are located at the same end of the air duct 11, the water tank 14 is connected to the air duct 11 from the middle, the atomizer 111 is located in the middle of the air duct 11, the connecting pipe 17 runs through the air duct 11, the filter net 114 is located in the middle of the connection between the water tank 14 and the air duct 11, the drain pipe 15 is connected to the water tank 14, and a valve is provided on the drain pipe 15. Support legs are fixed at the four corners of the bottom of the body 1, and the slide plate 113 runs through the body 1.

[0026] In the specific implementation process, Figure 2 and Figure 3As shown, when in use, the fan 13 draws the air carrying dust into the air duct 11, the protective net 12 protects the fan 13, the water pump 16 draws the water in the water tank 14 through the right-angle pipe 18 and the filter head 19, and injects the water into the atomizer 111 through the connecting pipe 17. The water in the atomizer 111 is sprayed out through the atomizing nozzle 112 to form a large amount of water mist. When the air in the air duct 11 passes through the water mist, the water mist absorbs the dust in the air and falls on the filter net 114. The dust is filtered through the filter net 114 and then flows into the water tank 14 to form a cycle. After long-term use, the filter net 114 pulls the vertical plate 11 It is taken out through the slide plate 113 for cleaning, and then reinserted for use after cleaning. The air passing through the atomizing nozzle 112 may still contain a small amount of dust. The drying plate 117 at the rear end of the air duct 11 absorbs the moisture in the air, and the activated carbon filter plate 118 adsorbs the remaining dust and harmful gases in the air. Through the coordinated use of the water pump 16, the connecting pipe 17, the right-angle pipe 18, the filter head 19, the atomizer 111 and the atomizing nozzle 112, the gas carrying dust is removed by the filter structure, and the water mist adsorbs most of the impurities in the air, thereby reducing the possibility of clogging of the filter structure.

[0027] Embodiment 2: In Embodiment 1, there is still the problem that the activated carbon filter plate in the filter structure is troublesome to replace, so on the basis of Embodiment 1, this embodiment also includes:

[0028] A square plate 2 is slidably provided in the body 1, a cover plate 21 is provided on the top of the square plate 2, a pair of slots 22 are provided in the square plate 2, a circular hole 23 is provided in the middle of the square plate 2, the circular hole 23 is the same size as the air duct 11, the circular hole 23 passes through the square plate 2, the pair of slots 22 both pass through the square plate 2, the circular hole 23 is connected with the air duct 11, the square plate 2 passes through the air duct 11, and a handle is fixed on the cover plate 21.

[0029] In the specific implementation process, Figure 1 and Figure 3 As shown, after the activated carbon filter plate 118 has been used for a long time, the cover plate 21 is lifted up by the handle, and the cover plate 21 drives the square plate 2 to move upward to be removed, and the fixing frame 116 in the slot 22 is pushed out, and the drying plate 117 and the activated carbon filter plate 118 are replaced, and then the fixing frame 116 is reinserted into the slot 22, and the replaced square plate 2 is reinserted into the body 1 to complete the replacement. Through the coordinated use of the square plate 2, the cover plate 21, the slot 22 and the round hole 23, the activated carbon filter plate 118 can be easily replaced after being used for a long time, which is very simple and convenient.

[0030] Specifically, the working principle and operation method of the utility model are as follows:

[0031] Step 1: When in use, start the fan 13, which draws the dust-carrying air into the air duct 11. The protective net 12 protects the fan 13, and starts the water pump 16. The water pump 16 draws the water in the water tank 14 through the right-angle pipe 18 and the filter head 19, and injects the water into the atomizer 111 through the connecting pipe 17. The water in the atomizer 111 is sprayed out through the atomizing nozzle 112 to form a large amount of water mist. When the air in the air duct 11 passes through the water mist, the water mist absorbs the dust in the air and falls on the filter 1 14, the filtered air flows into the water tank 14 through the filter screen 114 to form a cycle. After the filter screen 114 is used for a long time, the vertical plate 115 is pulled out through the slide plate 113 to clean it, and then it is reinserted for use after cleaning. The air passing through the atomizing nozzle 112 may still contain a small amount of dust. The drying plate 117 at the rear end of the air duct 11 absorbs the moisture in the air, and the activated carbon filter plate 118 absorbs the remaining dust and harmful gases in the air, so that the dust removal effect is better;

[0032] Step 2: After the activated carbon filter plate 118 has been used for a long time, lift the cover plate 21 by the handle, and the cover plate 21 drives the square plate 2 to move upward to remove it, and push out the fixing frame 116 in the slot 22, replace the drying plate 117 and the activated carbon filter plate 118, and then reinsert the fixing frame 116 into the slot 22, and reinsert the replaced square plate 2 into the body 1 to complete the replacement;

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
