Description
Technical field
This utility model relates to cooling system field, a kind of underground coal mine based on ground heat radiation centralized machinery cooling system.
Background technology
According to the data of Fushun Branch of China Coal Research Institute, in the coal gross reserves of China's prediction, there is 73.2% buried depth more than 1000m.Along with the increase of mining depth, mine Virgin rock temperature is more and more higher, and meanwhile, mechanization degree is more and more higher, and corresponding machinery heat radiation is the biggest.Thus, mine high-temperature heat evil will seem more and more prominent.Climatic regionalization has strong influence to work efficiency, the safety and health of underground operators, it is necessary to take corresponding measure to administer, it is ensured that there is suitable working environment down-hole, meets the requirement of " safety regulations in coal mine ".And it is current, China can run continuously and can reach codes and standards, the mine centralized machinery cooling system meeting production requirement has three kinds: the ground ice-cold system of centralized machinery, ground centralized mechanical water cooling system, heat radiation down-hole, ground centralized mechanical water cooling system, three kinds of systems are compared, heat radiation down-hole, ground centralized mechanical water cooling system optimal economic benefit, but this system yet suffers from this power consumption height, and security performance is low, the shortcoming that refrigerating speed is slow, effect is undesirable.
Utility model content
The purpose of this utility model is to provide a kind of underground coal mine based on ground heat radiation centralized machinery cooling system, with the problem solving to propose in above-mentioned background technology.
nullFor achieving the above object，This utility model following technical scheme of offer: a kind of underground coal mine based on ground heat radiation centralized machinery cooling system，Including machinery heat sink，Described machinery heat sink includes the air compressor being positioned at more than ground and the vaporizer located below ground level，Connected by the first circulation pipe between described air compressor and vaporizer，It is provided with hydraulic regulating valve on described first circulation pipe，And hydraulic regulating valve is positioned at more than ground，Connect to have on the second circulation pipe on described vaporizer and be provided with water circulating pump，The right-hand member of described second circulation pipe is provided with air cooler，And air cooler is positioned at the inner chamber of discharge pipe，The left side of described discharge pipe is fixedly connected with blast pipe，Described discharge pipe goes out to be provided with aerator with the connection of blast pipe，Air precooling machine it is provided with on described blast pipe，And air precooling machine is positioned at more than ground.
Preferably, described aerator is turbocharging type aerator.
Preferably, described hydraulic regulating valve is that electric hydaulic regulates valve.
nullCompared with prior art，The beneficial effects of the utility model are: this underground coal mine based on ground heat radiation centralized machinery cooling system，Air compressor and air precooling machine are arranged at more than ground，The heat produced when air compressor and the work of air precooling machine is dispersed in air，The heat produced is avoided to gather bottom mine，Causing air compressor to work the most in high temperature environments causes service life short，The heat simultaneously avoiding air compressor generation mixes with the air containing methane gas under mine，Cause the security incidents such as blast，Air inlet pipe arranges turbocharger，Air precooled for air precooling machine is compressed，Strengthen the cooling capacity of this system，Should underground coal mine based on ground heat radiation centralized machinery cooling system，Effectively enhance cooling capacity，Greatly improve the security performance of entirety simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1 machinery heat sink, 2 air compressors, 3 first circulation pipes, 4 hydraulic regulating valves, 5 vaporizers, 6 second circulation pipes, 7 water circulating pumps, 8 blast pipes, 9 air precooling machines, 10 aerators, 11 air coolers, 12 discharge pipes.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，A kind of technical scheme of this utility model offer: a kind of underground coal mine based on ground heat radiation centralized machinery cooling system，Including machinery heat sink 1，Machinery heat sink 1 includes the air compressor 2 being positioned at more than ground and the vaporizer 5 located below ground level，Connected by the first circulation pipe 3 between air compressor 2 and vaporizer 5，It is provided with hydraulic regulating valve 4 on first circulation pipe 3，And hydraulic regulating valve 4 is positioned at more than ground，Hydraulic regulating valve 4 regulates valve for electric hydaulic，Owing to the vertical height of the first circulation pipe 3 is higher，Electric hydaulic regulation valve is set and can effectively regulate the static pressure within the first circulation pipe 3，Avoid the first circulation pipe 3 internal pressure excessive，The first circulation pipe 3 is caused to burst，Cause security incident，Connect to have on the second circulation pipe 6 on vaporizer 5 and be provided with water circulating pump 7，The right-hand member of the second circulation pipe 6 is provided with air cooler 11，And air cooler 11 is positioned at the inner chamber of discharge pipe 12，The left side of discharge pipe 12 is fixedly connected with blast pipe 8，Discharge pipe 12 goes out to be provided with aerator 10 with the connection of blast pipe 8，Aerator 10 is turbocharging type aerator，Wind-force is more powerful，Effectively raise the cooling capacity of this system，Air precooling machine 9 it is provided with on blast pipe 8，And air precooling machine 9 is positioned at more than ground，Air compressor 2 and air precooling machine 9 are arranged at more than ground，The heat produced when air compressor 2 and air precooling machine 9 work is dispersed in air，The heat produced is avoided to gather bottom mine，Causing air compressor 2 to work in high temperature environments for a long time causes service life short，The heat simultaneously avoiding air compressor generation mixes with the air containing methane gas under mine，Cause the security incidents such as blast，Security performance is high.
Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
