Abstract

The utility model provides a blast drilling tunnel spray device. The blast drilling tunnel spray device is provided with a compressed wind leading pipe and a water source leading pipe. The compressed wind leading pipe and the water source leading pipe are all installed in a compressed wind storage casing pipe. The compressed wind storage casing pipe is provided with a high speed spray nozzle. A compressed wind accelerating pipe is arranged in the compressed wind storage casing pipe. The compressed wind accelerating pipe is a diameter changing pipe. The blast drilling tunnel spray device has the advantages of large atomization range, strong anti-shock capacity, safe work, simple structure, short service life, low cost, etc.

Description

Explosion digging laneway atomization mechanism
Technical field
The utility model relates to mine development end equipment, is a kind of atomization mechanism that uses when the explosion digging laneway.
Background technology
The blasting method of using in when driving is advanced in the ore deposit, the disappear measure of dirt that must take lowers the temperature.Normally used spray outfit is bulky, is generally 800 * 700 * 260, complex structure, and the poor stability of use, impact resistance is poor, and range of atomized flow is little etc.Disclosed in recent years automatic sprayer, it adopts compressed air is power, adopts the pneumatic logic technology to reach the purpose of depositing dust.Its deficiency is: functional reliability is poor, application life is short, range of atomized flow is little, impact resistance is poor, cost of production is high.
Summary of the invention
The purpose of this utility model is, a kind of explosion digging laneway atomization mechanism is provided, and it has, and range of atomized flow is big, strong shock resistance, safe and reliable, simple in structure, advantage such as application life is short, cost of production is low.
The utility model for achieving the above object, be achieved through the following technical solutions: it has the wind ingress pipe of pressure and water source ingress pipe, press wind ingress pipe and water source ingress pipe to be installed in and press in the wind storage sleeve pipe, press wind storage sleeve pipe to offer the high speed spout, press to be provided with in the wind storage sleeve pipe and press the wind accelerating tube, pressing the wind accelerating tube is reducer pipe.Press wind accelerating tube one end to be the open type inlet, its diameter is identical with pressure wind storage sleeve pipe, and the other end communicates with the high speed spout.Press wind accelerating tube arrival end diameter and press wind storage casing inner diameter identical, middle for pressing wind and mixed zone, water source, its diameter presses wind accelerating tube port of export diameter less than the mixed zone diameter less than arrival end.The port of export of water source ingress pipe places the mixed zone.
The utility model knows that through on probation its advantage is as follows: range of atomized flow is big, strong shock resistance, safe and reliable, far firing range, simple in structure, long service life, cost of production is low and it is nozzle specially used etc. not need to adorn in addition.
Description of drawings
Accompanying drawing 1 is the utility model structural representation; Accompanying drawing 2 is A-A sectional drawings in the accompanying drawing 1.
The specific embodiment
1 is to press wind ingress pipe, the 2nd, water source ingress pipe among the figure, it is pressed wind ingress pipe 1 and water source ingress pipe 2 to be installed in and presses in the wind storage sleeve pipe 7, press wind storage sleeve pipe 7 to offer high speed spout 9, press to be provided with in the wind storage sleeve pipe 7 and press wind accelerating tube 8, pressing wind accelerating tube 8 is reducer pipe.Press wind accelerating tube 8 one ends to be the open type inlet, its diameter is identical with pressure wind storage sleeve pipe 7, and the other end communicates with high speed spout 9.Press wind accelerating tube 8 arrival end diameters and press wind storage sleeve pipe 7 internal diameters identical, middle for pressing wind and mixed zone, water source 5, its diameter presses wind accelerating tube 8 port of export diameters less than mixed zone 5 diameters less than arrival end.The port of export of water source ingress pipe 2 places mixed zone 5.When the utility model uses, press wind ingress pipe 1 one ends and mine compressed air to join, water source ingress pipe 2 one ends and water source join, when pressing wind ingress pipe 1 to enter pressure wind accelerating tube 8 places, because pressure is identical, section dwindles herein, press the wind speed degree to significantly improve, pressure wind after the speed-raising is in the front portion of mixed zone, geomantic omen 5, shielding action because of the outlet 4 of water source ingress pipe 2, can produce low pressure zone near water source outlet 4, the water source that has only lower pressure can be broken endlessly to enter mixed zone 5, the high-pressure blast at 5 places cracks the tiny atomized water of poling to water in the mixed zone, acceleration by secondary reducing 6 places, 9 places penetrate at a high speed at the high speed spout, produce the mist jet, reach the purpose of spray cooling degree and dust.3 is pressure ventilation pipe outlets among the figure.
