Background technology
Can produce a large amount of dust in the coal production process, coal-winning machine and tunneling machine cutting process, raw coal is the main root that produces coal dust when conveyor system transportation and the transportation of employing mine car, a large amount of dust is the major hidden danger of harm workers ' health and safety.The dust disaster is the outstanding problem of dust work place safety in production, also is the major hidden danger that influences Safety of Coal Mine Production, is its explosivity on the one hand, and explosion energy is big, and can cause continuous blast, and has no sign before the blast, and harmfulness is very big; Coal-dust explosion is very big to destructiveness, a large amount of carbon monoxide that the back of especially exploding produces, and the people just can be poisoned to death at short notice, and on the other hand, dust can also cause that the miner changes lung absorption diseases such as anthraco-silicosis and anthracosilicosis disease.
At present, China adopts electrical equipment to realize the opening and closing of control at the dust falling system of down-hole application more.There are problems such as solenoid valve failure rate height and control section power taking inconvenience.And the mine network of rivers and pressure wind network gather, and take conveniently.Because not making electricity consumption as type of drive, do not exist and lose safety problems such as quick-fried.
The utility model content
The purpose of this utility model is to propose a kind of mining atomizing de-dusting system, is driving with the electricity to solve dust falling system of the prior art, has the problem of losing quick-fried potential safety hazard.
For reaching this purpose, the utility model by the following technical solutions:
A kind of mining atomizing de-dusting system, comprise supply channel Pneumatic gate valve control pipeline, on the described supply channel sprayer is installed, on the described supply channel Pneumatic gate valve control pipeline gas control two-position three-way valve open in usual is installed, described supply channel Pneumatic gate valve pneumatic line and double air controlled two-bit triplet valve air gate join; The air inlet port of described double air controlled two-position three-way valve joins through reducing valve and source of the gas, one end and the shuttle valve gas outlet of described double air controlled two-position three-way valve two control ends join, described shuttle valve air inlet port joins with normally closed type control valve and high-pressure air source, and the gas outlet of the other end and normally closed time-delay valve joins; The gas control end of described normally closed time-delay valve and air inlet port all join with the gas outlet of described double air controlled two-position three-way valve and the gas control end of two-position three-way valve open in usual.
Preferably, described normally closed type control valve can be a plurality of being arranged in parallel.
Preferably, described reducing valve output pressure is regulated between 0.1-1MPa.
Preferably, be connected with the water under high pressure strainer on the described sprayer.
Preferably, the diameter of described sprayer is 0.3-1.0mm.
The beneficial effects of the utility model are: owing to adopt mine compressed air as system's open and close and power, Pneumatic valve is installed as the switch of high service at supply channel, the pure pneumatic operation of system does not use any electrical equipment, guarantees mine safety; Because adopted to be connected with the water under high pressure strainer on the sprayer,
Cause spraying system to stop up so prevent mine water quality effectively, prolong the application life of depositing dust spraying.
Description of drawings
Fig. 1 connects schematic diagram for the pneuamtic part of a kind of mining atomizing de-dusting system that the utility model specific embodiment 1 provides;
Among the figure:
1, normally closed type control valve; 2, double air controlled two-position three-way valve; 3, normally closed time-delay valve; 4, two-position three-way valve open in usual; 5, reducing valve; 6 admission lines; 7, shuttle valve.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment, as shown in Figure 1, a kind of mining atomizing de-dusting system, comprise supply channel Pneumatic gate valve control pipeline, sprayer is installed on the supply channel, in order to prevent from causing because of the mine quality problem obstruction of sprayer, prolong the application life of sprayer effectively, so on sprayer, be connected with the water under high pressure strainer, adopt the impurity in the water under high pressure strainer filtering mine water, the water under high pressure strainer is spraying water through sprayer after mine water coarse filtration and the fine filtering.
For improving atomizing effect, system adopts micro-sprayer technology, sprayer diameter 0.3-1.0mm.
On the supply channel Pneumatic gate valve control pipeline gas control two-position three-way valve 4 open in usual is installed, described supply channel Pneumatic gate valve pneumatic line and double air controlled two-position three-way valve 2 gas outlets join; The air inlet port of described double air controlled two-position three-way valve 2 joins through reducing valve 5 and high-pressure air source, one end and shuttle valve 7 gas outlets of 2 liang of control ends of described double air controlled two-position three-way valve join, described shuttle valve 7 air inlet ports and normally closed type control valve 1 join with high-pressure air source, and the gas outlet of the other end and normally closed time-delay valve 3 joins; The gas control end of the air inlet port of the gas control end of described normally closed time-delay valve 3 and the gas outlet of described double air controlled two-position three-way valve 2 and two-position three-way valve open in usual 4 joins.
