Abstract
The utility model relates to a water chiller unit used in coal mine underground, which is a complete set of technical equipment mainly used for controlling high temperature and heat harm of mining working surface of coal mine underground or non-coal mine underground, and comprises a screw-type refrigerating compressor unit, a metal hose and an auxiliary module. A refrigerating compressor absorbs refrigerant from an evaporator and presses the refrigerant into a condenser; in the condenser, the refrigerant transmits heat to cooling water and is condensed into liquid state, and finally enters the evaporator after flow and pressure reduction by an expansion valve; the liquid refrigerant absorbs the heat of cold water in the evaporator, is gasified into gas state, absorbed into the compressor, circulated subsequently and continuously, keeps absorbing the heat of the cold water, reduces the temperature of the cold water, the cooled cold water goes through, and is sent to places needed to be chilled by a water pump which is serially connected with the evaporator. The water chiller unit used in coal mine underground adopts brand-new design, has obvious refrigerating effect, small size, is convenient to move, has reliable performance, runs stably, and can be widely applied to the high temperature and heat harm control of the mining working surface of the coal mine underground or non-coal mine underground.
Description
Technical field
The utility model relates to a kind of refrigeration unit, particularly relates to a kind of handpiece Water Chilling Units of underground mine use.
Background technology
When the air themperature of subsurface environment surpasses 28 ℃, miner's morbidity is obviously risen, administration even death by accident in beginning when surpassing 30 ℃ to occur, according to the incomplete statistics since 1984, according to the incomplete statistics since nineteen eighty-three, hundreds of people Yin Gaowen heatstroke has taken place and has fallen in a swoon in the underground work place in China's coal-mine.New river in Shangdong Province Sun Cunkuang is following higher 1.83 times than normal temperature (being lower than 28 ℃) at the miner's of down-hole high-temperature operation place operation the incidence of disease in (downhole cooling system put into operation before) before 1984,3.61 times of Gao Shida." mine main getting working face air themperature must not surpass 26 ℃ to the 102nd regulation of China's " safety regulations in coal mine ", and the air themperature of dynamo-electric chamber must not be above 30 ℃; ... the air themperature of getting working face surpasses 30 ℃, when the air themperature of dynamo-electric chamber surpasses 34 ℃, must stop operation ".
China is first big coal country in the world, also is the many countries of high-temperature mine quantity.China's pit mining depth-averaged extends to the deep with the speed of 11m every year.At present, the average mining depth of China coal mine under the unified-allocation system is about 680m, and some pit mining degree of depth has reached 900～1300m.According to incompletely statistics, China surpasses 30 ℃ to coal mine excavation work plane air themperature surplus in the of existing 130 at present, and the mining depth of many mines is below 800m.Show in the gross reserves that China predicts, 73.2% reserves buried depth is arranged below 1000m according to coal resources exploitations and protection of resources data.This shows that mine elevated temperature heat evil is not only present problem demanding prompt solution, and in the long term, it will further be developed the deep coal resources from now on to China and will have strategic importance.
Mine deep elevated temperature heat evil problem is very serious, and especially new well mine construction stage and old well depth portion open up more outstanding.
Xuzhou San He point ore deposit for example, mine mine construction stages such as the Pan Yi of Huainan Mining Group company, Pan three ore deposits all reach 30～35 ℃ elevated temperature heat evil, and programming is affected.
The new Sun Cunkuang of river in Shangdong Province Mining Group company-800m level development driving, the Fengcheng is built Xin Kuang-600m level development driving and is run into 31～35 ℃ elevated temperature heat evil problem, ore deposit, the peak-to-peak group company Chinese parasol tree village runs into high-temperature-hot-water at driving face and gushes out, and causes the driving face wind-warm syndrome up to 34 ℃.
Similarly the elevated temperature heat evil is many in addition in China, and the very shortage of China's present mine deep getting working face elevated temperature heat evil control equipment can't be satisfied China's mine deep safety, be produced efficiently, and the sustainable development of restriction China mining of deep mine needs.
At present, the main employing of mine elevated temperature heat evil control strengthened the environment temperature that air flux is improved getting working face, to not implementing the local or concentrated artificial cooling measure in down-hole with the general employing handpiece Water Chilling Units that venting practice solves.
But the volumes that are structure as a whole such as conventional handpiece Water Chilling Units refrigerant compression, evaporimeter and condenser are big, the narrow and small transportation in space, down-hole is installed inconvenient, and the down-hole inconvenient debugging adapts to colliery and non-coal mine down-hole application place better and adopt the branch body structure to effectively reduce volume.
Summary of the invention
It is a kind of at the narrow and small situation in mining of deep mine space that the purpose of this utility model is to provide, design that refrigeration is obvious, volume is little, conveniently moving, dependable performance, operate steadily, can be applicable to the underground mine use handpiece Water Chilling Units of colliery and non-coal mine down-hole mining work plane elevated temperature heat evil control.
The purpose of this utility model is achieved through the following technical solutions:
The underground mine use handpiece Water Chilling Units, adopt and divide body structure, comprise: screw type refrigerating compressor group, subsidiary engine module, connecting screw rod formula refrigeration compressor set are connected metal hose with the metal hose and the evaporimeter of subsidiary engine module, the branch body structure that the underground mine use handpiece Water Chilling Units adopts has, refrigeration compressor set and subsidiary engine module, and aspirating air pipe is equipped with on stop valve and stop valve and the feed liquid pipeline thereof stop valve and stop valve is housed; Screw type refrigerating compressor links to each other by being connected metal hose with evaporimeter, and the refrigeration compressor compression port links to each other with condenser, and condenser is connected the back and links to each other with evaporimeter with choke valve; Evaporimeter links to each other with compressor suction, and the said equipment circulates continuously successively and joins, and evaporimeter is connected with the water pump of series connection.
Described underground mine use handpiece Water Chilling Units, described metal hose adopts the armouring metal hose, and the DN6 stop valve is installed on the metal hose tube wall.
