Description

Adjustable blasting remote compressed air sprayer

technical field

The invention relates to a dust-reducing spray device, in particular to an adjustable blasting remote compressed air sprayer.

Background technique

According to AQ1020-2006 "Coal Mine Dust Prevention and Control Technical Specifications", high-pressure spray or compressed air spray must be used on blasting face. At present, remote spraying is used on blasting face in our mine. The spraying device adopts the natural pressure of water supply pipeline, up to If it is less than 8Mpa, it cannot meet the requirements of the AQ1020-2006 industry standard. Remote spray has a long spray distance but the atomization effect is not good. Ordinary spray spray has good atomization effect but the spray distance is short and cannot be sprayed to the blasting site. If the purchase of booster equipment not only requires expensive investment, the price is more than 200,000 yuan, and After using booster equipment, it is easy to cause explosion of underground field equipment, poor protection of high-pressure pipelines, and unsafe hidden dangers such as pressure injury. There are disadvantages in terms of cost investment and on-site safety management.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

The present invention is shown in Fig. 1, a kind of remote air pressure sprayer of adjustable blasting, comprises air inlet duct 10, and the right end of described air inlet duct 10 is fixedly connected with air inlet pipe joint 9, and the air inlet duct 10 The left end is connected with a three-way joint 12, and the feature is that: the upper joint of the three-way joint 12 is fixedly connected with a water inlet member, and the lower joint of the three-way joint 12 is fixedly connected with a water inlet member. In this embodiment, the water inlet member includes a casing 1, the casing 1 is internally threaded with a hollow shaft 2 with a different diameter, and the right end of the hollow shaft 2 with a different diameter is connected with a water inlet pipe joint 8 through a connection joint 7, and the casing 1 An air outlet gap 13 is designed between the left part and the hollow shaft 2 with different diameters. In this embodiment, the hollow shaft 2 with different diameters includes a hollow shaft body 5, the hollow shaft body 5 is designed with a through hole, the left end of the hollow shaft body 5 is designed with external threads, and the right end of the hollow shaft body 5 is designed with threads The joint 6, the left end of the hollow shaft body 5 is designed with a threaded pipe 14, the outer periphery of the hollow shaft body 5 is designed with a gasket groove 3, the gasket groove 3 is provided with an air-leakage-proof gasket 4, and the air-leakage gasket 4 is connected to the shell 1 Seal fit. In this embodiment, the diameter of the left part of the through hole is smaller than that of the right part. In this embodiment, a check valve 11 is fixedly connected between the air inlet duct 10 and the three-way joint 12 . In this embodiment, the diameter of the left part of the hollow shaft 2 with different diameters is 3-5 mm. In this embodiment, the hole diameter of the left part of the hollow shaft 2 with different diameters is 4 mm. In this embodiment, the diameter of the right part of the hollow shaft 2 with different diameters is 7-10 mm. In this embodiment, the diameter of the right hole of the hollow shaft 2 with different diameters is 8 mm.

When the present invention is used, the ratio of air and water can be adjusted by adjusting the cooperation between the shell and the hollow shaft with different diameters, and the amount of air intake can be adjusted to achieve the best effect of dust reduction and atomization. Because the aperture of the left part of the hollow shaft with different diameters is smaller than the aperture of the right part, the purpose of pressurization is achieved; the air inlet pipe is connected through the air inlet pipe joint, and the water inlet pipe joint is connected with the water inlet pipe.

The main structure of the adjustable blasting remote compressed air sprayer is an inner wire steel pipe with a diameter of 38mm, a wall thickness of 4mm and a length of 200mm as the air-water mixing capsule, an outer diameter of 30mm with an outer threaded water guide pipe as the water inlet pipe, and a 6-point one-way valve connected to the air inlet pipe. The spray device has two water inlets, one air inlet and two air mist outlets. The working principle is: the pressure water enters the spray tube capsule, the pressure wind mixes with the pressure water along the thread in the tube capsule, and under the action of the wind pressure, two dispersed aerosol sprays are formed to cover the blasting site. The spray range of the spray device can reach 11m, and the aerosol coverage width can reach 5m. It can effectively cover the large-section roadway with aerosol, and the atomization effect is good, which effectively makes up for the fact that the original spray pressure cannot reach 8Mpa and cannot cover the whole area. section problem. The dust reduction rate can be increased by more than 70%. At the same time, the best effect of the spray can be adjusted by adjusting the gap between the thread at the nozzle and the nozzle, so as to achieve the farthest spray range and good atomization.

The use of the adjustable blasting remote compressed air sprayer can effectively reduce the high concentration of dust generated during the blasting of the working face and improve the safety guarantee factor. At the same time, the production cost of the adjustable blasting remote compressed air sprayer is low, and the self-made processing only costs about 350 yuan, while the market purchase The finished compressed air spray needs more than 2,000 yuan, and there is no ideal spray product at present, which greatly saves the cost of investment. The long-distance pressurized air sprayer for long-distance blasting can save more than 30,000 yuan in safety costs and requires less maintenance. The adjustable blasting remote compressed air sprayer can effectively solve the problem that the blasting spray in the mine can not reach 8MPa and cannot cover the whole section. Effect.

The above-described embodiments are only described to the preferred implementation of the present invention, and are not intended to limit the concept and protection scope of the present invention. Various modifications and improvements made in the scheme should fall within the protection scope of the present invention.
