Abstract

The present invention discloses an automatic sprayer of blasting, which is composed of a spray gun body and a nozzle. The tail of the spray gun body is provided with a high-pressure wind inlet pipe and a high-pressure water inlet pipe. The nozzle is a wedge-shaped nozzle. The upper surface, the lower surface, the front surface and the back surface of the wedge-shaped nozzle are provided with spraying holes. A high-pressure blower which supplies wind to the high-pressure wind inlet pipe is provided with a blasting vibration automatic opening device. The nozzle is installed in the middle part of the laneway top which is separated from the working surface for 25-30 meters. The automatic sprayer of blasting of the invention has the advantages of: safe and convenient using, good construction environment, capability for removing dust instantly, and water resource saving.

Description

A kind of automatic sprayer of blasting
Technical field
The present invention relates to a kind of dust arrester, especially a kind ofly be used for flat (inclined gallery) two of mine construction, the automatic sprayer of blasting that the process of blowing out is implemented moment auto spraying depositing dust is built in the third stage of the project pick.
Background technology
At present in colliery two, the third stage of the project work progress, all need blow out watering and lowering dust according to rules when the each explosion of tunnelling, blow out the back at every turn to open time of spraying longer because of hydraulic pressure pressure causes for a short time, dust removing effects is poor.Putting three cyclic advances according to three, eight dutys calculates: 1 cyclic advance is put big gun twice, once blow out back depositing dust minimum needs (10-15 minute) the watering and lowering dust time, water is made an appointment with (40-50 kilogram), and blow out watering and lowering dust with regard to needs (60-90 minute) watering and lowering dust (240-300 kilogram) working day.There is following shortcoming in this watering and lowering dust mode: the method opening time is long, and water resource waste is serious, inefficiency, and construction environment is poor, potential safety hazard is many.Therefore, design a kind of safe and convenient to use, construction environment good, can the moment dedusting, the automatic sprayer of blasting of conserve water resource, be the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides a kind of automatic sprayer of blasting.
The technical scheme that the present invention solves its technical problem is:
A kind of automatic sprayer of blasting, form by gun body and shower nozzle, afterbody at gun body is provided with high-pressure blast blast pipe and water under high pressure water inlet pipe, described shower nozzle is the wedge shape shower nozzle, upper and lower, forward and backward four sides at the wedge shape shower nozzle is provided with spray holes, be provided with the concussion of blasting automatic open device for the high pressure blower of high-pressure blast blast pipe air feed, the high-pressure hydraulic pump of supplying water for the water under high pressure water inlet pipe is provided with the concussion of blasting automatic open device, and nozzle is installed in the centre apart from the top, tunnel of work plane 25-30 rice.
The technical scheme that the present invention solves its technical problem can also be:
The present invention is equipped with the high-pressure blast control valve on the high-pressure blast blast pipe, the water under high pressure control valve is installed on the water under high pressure water inlet pipe.
High pressure blower of the present invention is connected with the high-pressure blast control valve by the high-pressure blowing-in flexible pipe, and high-pressure hydraulic pump is connected with the water under high pressure control valve by high pressure flexible water hose.
The material of gun body of the present invention is that diameter is the seamless steel pipe of 20mm, and described shower nozzle is processed by the steel pipe of same material.
The length of gun body of the present invention is 700mm, and the length of described shower nozzle is 70mm, and the spacing of described spray holes is 3mm, and the aperture is 1.5-2mm.
High-pressure blowing-in flexible pipe of the present invention is formed by connecting by the wind band of diameter 19mm, long 10000mm, and described high pressure flexible water hose is formed by connecting by the water band of diameter 12mm, long 10000mm.
The invention has the beneficial effects as follows:
Will (artificial auxiliary) opening water curtain watering method changes into and blows out after the auto spraying system teams and groups and only blow out watering and lowering dust and just can save (20-30 minute) the watering and lowering dust time, water is (5-10 kilogram) approximately, putting three cyclic advances according to three, eight dutys calculates: 1 cyclic advance is put big gun twice, once blow out back depositing dust minimum needs (3-5 minute) the watering and lowering dust time, blow out watering and lowering dust with regard to needs (18-30 minute) watering and lowering dust a working day.Calculate according to transforming the back: 87600 kilograms of energy using water wisely in a year, can save time about 182.5 hours, improved the spraying ability greatly, on-the-spot result of use is good, has both guaranteed safety in production, has improved economic benefit again.
