Technical Field

[0001] The utility model relates to the field of coal mine dust removal equipment, in particular to a pneumatic wet dust collector. Background Art

[0002] With the continuous development of the development and utilization of mineral resources, the dust problem generated in the mining production process is becoming more and more serious. As one of the five major natural disasters in mines, the tiny particles of coal dust not only affect the health of front-line workers underground (causing pneumoconiosis), but more seriously, when the concentration ratio of dust and oxygen reaches a certain limit, the probability of major accidents (coal dust explosions) increases dramatically, and the degree of harm is self-evident. Excessive coal dust concentration not only affects the air quality of the underground mining face, but also reduces the visibility of workers, which brings inconvenience to the front-line workers and increases the probability of work-related accidents. Compared with gas explosions, coal dust and coal explosions have stronger impact energy, longer combustion time, and produce more carbon monoxide. Utility Model Content

[0003] In response to the problems existing in the background technology, a pneumatic wet dust collector is proposed. A wet dust removal component is set up, and a pneumatic motor is used to provide kinetic energy to drive the fan blades to rotate. At the same time, the underground water is atomized and sprayed out through the wind and water linkage to increase the contact volume between the wind and water and the coal dust, thereby improving the dust reduction efficiency.

[0004] The utility model provides a pneumatic wet dust collector, comprising a dust collection cylinder with two open ends and a wet dust collection component located in the dust collection cylinder. The wet dust collection component is provided with a nozzle and a fan blade, and uses the inlet and outlet gas as the power to drive the fan blade to rotate and generate airflow, and at the same time, it is linked with the water droplets sprayed from the nozzle to wet and collect dust.

[0005] Preferably, the wet dust removal assembly includes an air motor and a rotating shaft connected to the rotating end of the air motor; the fan blades are fixedly arranged on the rotating shaft; and the nozzle is arranged on the rotating shaft.

[0006] Preferably, it also includes an air pump; an air inlet pipe is arranged at the air inlet end of the pneumatic motor, and an air outlet pipe connected to the air pump is arranged at the air outlet end.

[0007] Preferably, the wet dust removal assembly also includes a mounting frame mounted on the inner wall of the dust removal cylinder and rotatably connected to the rotating shaft.

[0008] Preferably, a filter is also provided on the dust removal cylinder; a water inlet pipe is provided at the water inlet end of the filter, and a water outlet pipe rotatably connected to the nozzle is provided at the water outlet end.

[0009] Preferably, protective nets are arranged on the two open ends of the dust removal cylinder, and a support seat is arranged at the bottom.

[0010] Preferably, a dirt collecting box is provided at the dust outlet end of the dust collecting cylinder; the dirt collecting box is connected to the inner space of the dust collecting cylinder from the bottom and a sewage discharge pipe is provided.

[0011] Compared with the prior art, the utility model has the following beneficial technical effects:

[0012] 1. The utility model is provided with a wet dust removal component, which uses a pneumatic motor to provide kinetic energy to drive the fan blades to rotate. The rotation of the fan blades creates a negative pressure environment, sucking the dust into the dust removal cylinder. At the same time, the underground water filtered by the filter is sprayed out through the nozzle after being atomized, humidifying the sucked dust. Through the wind and water linkage, the volume of wind and water in contact with coal dust is increased, and the dust reduction efficiency is improved.

[0013] 2. The utility model adopts a filter as a pre-treatment to filter and clean the water flow, thereby preventing the water flow from blocking the nozzle of the nozzle, greatly improving the use effect of the nozzle, and can also reduce the pressure in the pipeline, protect the equipment, and reduce manual maintenance and replacement costs.

DETAILED DESCRIPTION

[0020] Embodiment 1

[0021] like Figure 1-Figure 3 As shown, the utility model provides a pneumatic wet dust collector, which includes a dust removal cylinder 1 and a wet dust removal component 4.

[0022] like Figure 4As shown, the wet dust removal component 4 is located in the dust removal cylinder 1, and includes an air motor 401, a rotating shaft 405, a nozzle 406 and a fan blade 404. The rotating shaft 405 is connected to the rotating end of the air motor 401; the fan blade 404 is fixedly arranged on the rotating shaft 405 and rotates synchronously with it; the nozzle 406 is arranged on the rotating shaft 405 and sprays water mist as it rotates. The wet dust removal component 4 uses the gas in and out as the power to drive the fan blade 404 to rotate and generate airflow, and at the same time, it is linked with the water droplets sprayed by the nozzle 406 to wet and collect dust.

[0023] The wet dust removal assembly 4 also includes an air pump 2; an air inlet pipe 403 is provided at the air inlet end of the air motor 401, and an air outlet pipe 402 connected to the air pump 2 is provided at the air outlet end. The air motor 401 drives the fan blade 404 to rotate through the high-pressure airflow, and is the main power conversion source.

[0024] It should be further explained that the wet dust removal assembly 4 also includes a mounting frame 407 mounted on the inner wall of the dust removal cylinder 1 and rotatably connected to the rotating shaft 405 .

[0025] It should be further explained that a filter 3 is also provided on the dust collecting cylinder 1; a water inlet pipe 301 is provided at the water inlet end of the filter 3, and a water outlet pipe 302 that is rotatably connected to the nozzle 406 is provided at the water outlet end. The filter 3 is a pre-treatment structure for water supply, and has a built-in filter element. The filter element can be backwashed by connecting a high-pressure water pipe to the water outlet pipe 302, and the cleaning is convenient and efficient. The filter 3 filters and cleans the water flow, mainly filtering and removing impurities such as solid particles with slightly larger diameters in the water flow, such as mud and rust, so that the pneumatic wet dust collector will not block the nozzle of the nozzle 406 due to the water flow introduced by itself, which greatly improves the use effect of the nozzle 406, and also reduces the pressure in the pipeline, protects the pneumatic wet dust collector, and reduces the cost of manual maintenance and replacement.

[0026] Embodiment 2

[0027] like Figure 1-Figure 3 As shown, the utility model provides a pneumatic wet dust collector, which includes a dust removal cylinder 1 and a wet dust removal component 4.

[0028] The dust collecting cylinder 1 is open at both ends and is designed from the perspective of ergonomics, so that coal mining can be carried out in a safer, healthier and more comfortable environment. It is treated with stainless steel sandblasting technology to increase corrosion resistance and aesthetics while improving the quality and service life of the main body. Protective nets are set on the two open ends of the dust collecting cylinder 1, and a support seat is set at the bottom. A dirt collecting box 101 is set at the dust outlet end of the dust collecting cylinder 1; the dirt collecting box 101 is connected to the internal space of the dust collecting cylinder 1 from the bottom, and a sewage pipe is set. The collected sewage containing wet dust is collected in the dirt collecting box 101, which is convenient for flowing out of the equipment.

[0029] The working principle of the utility model is as follows: the wet dust removal component 4 is an internal design, and the pneumatic motor 401 drives the fan blade 404 to rotate through the high-pressure airflow, which is the main power conversion source. The rotation of the fan blade 404 creates a negative pressure environment, sucking the dust into the dust removal cylinder 1. At the same time, the underground water filtered by the filter 3 is sprayed out through the nozzle 406 after being atomized, humidifying the inhaled dust. Through the wind and water linkage, the volume of wind and water in contact with coal dust is increased, and the dust reduction efficiency is improved.

[0030] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
