Description

Technical Field

[0001] The utility model relates to a dust-proof atomizing device, in particular to a small-sized dust-proof atomizing device for mining, and belongs to the technical field of mine dust removal. Background Art

[0002] In recent years, with the increasing degree of mechanization in mine excavation, the intensity of mine mining has gradually increased, and the amount of dust generated in underground mining faces has increased dramatically. Once the dust cannot be cleaned up in a timely and effective manner, it may enter the work site with the wind flow in the mine, making the working face environment significantly worse. This will not only cause a serious decrease in visibility at the working face, affecting the sight of drivers in coal mining machines and tunneling machines, and have a certain impact on production safety, but also induce pneumoconiosis in mining workers, threatening the lives and health of mining workers. It will also cause high concentrations of coal dust at the working face, posing a safety hazard of coal dust explosion.

[0003] In order to reduce the dust concentration on the working face, an atomizing device is generally used to clean the dust in a timely manner. For example, the ventilation and water pipes are connected to the internal and external spray nozzles of the coal mining machine and the tunneling machine, and the atomized water vapor is used to capture the dust and blow away the local gas generated when cutting the coal body. However, the existing mining atomizing devices have the following technical defects: First, the device is large in size, which is not only inconvenient to move, but also laborious to operate, which increases the workload of the mining workers and makes it difficult to perform special dust removal operations on the local mining face; second, the device needs to be connected to electricity for use, which not only increases the risk of gas and coal dust explosions, but also easily causes serious accidents.

[0004] Therefore, in order to improve the above-mentioned technical defects, it is urgent to develop and design a small-scale dust-proof atomization device for mining. Summary of the invention

[0022] Furthermore, the utility model provides that the compressed air power assembly further comprises a hanging handle, and the hanging handle is installed on the bottom surface of the fan outer shell cylinder.

[0023] In summary, the working principle of the utility model is as follows: compressed air and water enter the wind-water linkage spray ring from the power compressed air pipeline and the water supply pipeline at the mining working face respectively, are first mixed inside the wind-water linkage spray ring, and then spray mist droplets from the spray head and spray to the mining working face, thereby achieving the effect of wind-water linkage mixed spray dust removal.

Spatially related terms, such as "upper", "lower", "left", "right", "front", "back", "middle", "both sides", etc., may be used in the text to facilitate the description of the relationship between an element or feature shown in the figure and another element or feature.

[0034] An embodiment of the present utility model: Figure 1 As shown, a small-scale dust prevention atomization device for mining is mainly composed of a compressed air power component and an atomization diffusion component.

[0035] The compressed air power assembly includes a pneumatic fan 1, a filter 2, and a first air source pipeline 3, which are described in detail as follows.

[0036] The pneumatic fan 1 comprises a fan outer shell 11 , a fan bracket 12 installed inside the fan outer shell 11 , an air motor 13 installed on the fan bracket 12 , and a wind impeller 14 installed on the front output shaft of the air motor 13 .

[0037] In a specific implementation, the fan bracket 12 is installed on the inner wall of the fan outer shell 11 to provide support for the pneumatic motor 13, so that the pneumatic motor 13 and the impeller 14 are fixed on the central axis inside the fan outer shell 11. The pneumatic motor 13 is used to drive the impeller 14 through the wind source, so that the pneumatic fan 1 rotates by the wind source without the action of electricity. In addition, the pneumatic motor 13 can adopt a gear-type pneumatic motor, which has a simple structure, is durable and reliable, and has a long service life.

[0038] The filter 2 is installed on the outer wall of the fan outer shell 11 , with its inlet connected to one end of the first air source pipeline 3 , and its outlet passing through the fan outer shell 11 to connect to the air inlet at the rear end of the pneumatic motor 13 .

[0039] One end of the first air source pipeline 3 is connected to the inlet of the filter 2, and the other end thereof is movably connected to the power compressed air pipeline of the mining working face.

[0040] In specific implementation, the first air source pipeline 3 is detachably connected to a joint of the power compressed air pipeline of the mining working face, and is used to provide an air source for the pneumatic fan 1. When the device of the present invention needs to be moved, the first air source pipeline 3 and the power compressed air pipeline can be separated. The filter 2 is used to remove oil and water from the compressed air provided by the first air source pipeline 3. In addition, a control valve is installed on the filter 2. Adjusting the control valve can allow the compressed air to be introduced into the pneumatic motor 13 through the air intake hose, thereby providing a clean air source for the pneumatic fan 1.

[0041] From the above, it can be seen that the compressed air enters the filter 2 from the power compressed air pipeline at the mining working face, and after the impurities are removed by the filter 2, it enters the pneumatic motor 13 of the pneumatic fan 1, driving the pneumatic motor 13 to rotate, thereby driving the impeller 14 to rotate. Thereafter, the impeller 14 performs work on the air, so that the air has a certain energy and is discharged from the air outlet at the front end of the fan outer shell 11 at a certain speed, providing power compressed air for the atomizing and diffusing component, thereby blowing the atomized water droplets in the atomizing and diffusing component toward the mining working face.

[0042] In addition, the pneumatic fan 1 adopts a structure in which compressed air at the mining face drives the pneumatic motor 13 to drive the impeller 14 to rotate. It does not need to be connected to electricity for use, has the advantages of safety and explosion-proof, is suitable for ventilation in a variety of working environments, and can be used as local ventilation and exhaust equipment in mines, tunnel projects, etc.

[0043] like Figure 1 As shown, the atomizing and diffusing assembly includes a diffuser 7, a second air source pipeline 8, and a water source pipeline 9, which are specifically described as follows.

[0044] The diffuser 7 includes a spray expansion tube 71 , a spray ring bracket 72 installed inside the spray expansion tube 71 , and a wind-water linkage spray ring 73 installed on the spray ring bracket 72 .

[0045] The spray expansion tube 71 is a trumpet-shaped one with an inner diameter that gradually expands outwards, and is installed at the air outlet at the front end of the fan outer shell 11 .

[0046] In specific implementation, the spray expansion tube 71 is mainly used to guide the spray.

[0047] The wind and water linkage spray ring 73 is fixed on the inner wall of the diffuser 7 through the spray ring bracket 72, and spray heads 74 are evenly installed on its front end surface, and its bottom is connected to the second wind source pipeline 8 and the water source pipeline 9 respectively.

[0048] In specific implementation, the spray ring bracket 72 is mainly used to fix the wind and water linkage spray ring 73. The wind and water linkage spray ring 73 is used to spray wind and water linkage mixed mist droplets from the spray head 74, and atomize and remove dust on the mining working face under the action of the supplementary wind source of the rear pneumatic fan 1.

[0049] One end of the second air source pipeline 8 is connected to the bottom of the wind-water linkage spray ring 73, and the other end thereof is movably connected to the power compressed air pipeline of the mining working face.

[0050] One end of the water source pipeline 9 is connected to the bottom of the wind and water linkage spray ring 73, and the other end thereof is movably connected to the water supply pipeline of the mining working face.

[0051] In specific implementation, the other end of the second air source pipeline 8 is also connected to the power compressed air pipeline at the mining working face to provide an air source for the wind and water linkage spray ring 73. The water source pipeline 9 is connected to the water supply pipeline at the mining working face to provide a water source for the wind and water linkage spray ring 73. When the device of the present invention needs to be moved, the second air source pipeline 8 and the power compressed air pipeline can be separated, and the water source pipeline 9 and the water supply pipeline can be separated.

[0052] As can be seen from the above, the working process of the utility model is as follows: compressed air and water enter the wind-water linkage spray ring 73 from the power compressed air pipeline and the water supply pipeline at the mining working face respectively, are first mixed inside the wind-water linkage spray ring 73, and then sprayed out from the spray head 74 to form mist droplets, thereby achieving the effect of wind-water linkage mixed spray. At the same time, compressed air enters the filter 2 from the power compressed air pipeline at the mining working face, first removes impurities through the filter 2, and then provides power to the pneumatic fan 1, driving the pneumatic fan 1 to rotate, and providing a supplementary wind source for the atomization and diffusion component in front. In addition, the supplementary wind source blows the mist droplets along the spray outer expansion tube 71 toward the mining working face.

[0053] Moreover, compared with the single use of water spray to atomize and remove dust from the mining working face, the technical solution of the wind and water linkage mixed misting of the atomizing and diffusing component can not only significantly reduce the water consumption and prevent excessive mud and water on site, but also make the water atomization more complete and the effective area more targeted, thus improving the dust reduction effect. At the same time, the pneumatic fan 1 of the compressed air power component can supplement the wind source for the wind and water linkage spray ring 73, enhance the misting effect, and forcefully blow the mist droplets sprayed from the spray head 74 to the designated area, thereby enhancing the effect of local dust removal, and can timely and effectively blow away local gas, so that the fire prevention work of gas control has a more reasonable ventilation method.

[0056] In specific implementation, the pressure control valve 31 can display the flow meter pressure, and is used to adjust the wind pressure in the first wind source pipeline 3 and the second wind source pipeline 8 (control the wind pressure at 0-0.6MPa) and the water flow in the water source pipeline 9 as needed, so as to adjust the wind pressure and water flow at any time, especially in the case of unstable compressed air and water supply, to ensure the reasonable ratio of wind and water, thereby adjusting the mist output rate and mist output concentration of the wind and water linkage spray ring 73. In addition, the waste of compressed air and water supply is reduced, and the energy saving and emission reduction effect is considerable.

[0057] like Figure 1 As shown, in some other specific embodiments of the present invention, the rest are the same as the above embodiments, except that a portable connector 32 is installed at the other end of the first air source pipeline 3, the second air source pipeline 8, and the water source pipeline 9 respectively.

[0058] In specific implementation, the portable connector 32 can adopt a quick connector, etc., to facilitate the rapid connection or disassembly between the first air source pipeline 3, the second air source pipeline 8 and the power compressed air pipeline of the industrial mining working face, and between the water source pipeline 9 and the water supply pipeline of the industrial mining working face, making the operation more efficient and convenient.

[0064] During specific implementation, the hanging handle 6 is used to hang the device on the anchor rod, so as to facilitate the placement of the device at a suitable position for performing spraying operations.

[0065] In summary, the utility model is placed at a certain distance behind the mining working face, with the spray port of the diffuser 7 facing the working face, and the first air source pipeline 3 and the second air source pipeline 8 of the device are respectively connected to the power compressed air pipeline of the mining working face, and the water source pipeline 9 is connected to the water supply pipeline of the mining working face.
