Description
Technical field
The invention belongs to concrete sprayer field, be specifically related to a kind of coal mine wet-type and stir hydraulic concrete spraying machine.
Background technology
The tunnel of underground coal mine is the safe space integrating Coal Transportation, pedestrian, ventilation, escaping function.So be necessary to the safety support in tunnel be also very important.Drift support type has a variety of: wooden supporting, steel lining, bracket support, bolt support, bolting with wire mesh and concrete ejection supporting etc., and the safest, the most reliably, the most general support pattern or the supporting of sprayed mortar.At present, the machinery that colliery is used for concrete spraying support is the PZ type rotator type pulp shooting machine continued to use nearly 30 years substantially, and its advantage is that volume is little, lightweight, cheap, uses simple to operate, and workman is easy to grasp; Shortcoming is that work plane dust is large, large to the occupational hazards of worker.There is rotator type wet-spraying machine in recent years, this equipment is on PZ type basis, and set up priming apparatus at pulp shooting machine feeding mouth, work plane dust can decrease in theory, but owing to being the deadly defect adopting pressure wind delivering concrete, cause in the course of work, occurring frequent plugging, injection work can not normally be carried out, and workman follows the line of least resistance, dislikes trouble in real work, often also seldom add water, even do not add water, under such conditions, job site still dust is filled the air.
The reason of the pneumoconiosis caused because of sprayed mortar and present situation: the dust of sprayed mortar association mainly respirable size below 10 μm, cement grit containing about 10% free silicon, this is one of main dust source in Mine Production, this dust very easily causes serious occupational hazards, i.e. pneumoconiosis.According to Some Domestic mining area field actual measurement results, in sprayed mortar operation process, operating area mean dust concentration is generally 20 ~ 50mg/m
3left and right, concrete batching place and injector head place dust concentration are about 150 ~ 200mg/m
3, even can up to 400 ~ 1000mg/m with material loading place dust concentration around spraying machine
3above.Visible, the dust concentration that sprayed mortar produces is far beyond national standard (10mg/m
3).Make for a long time so, miner very easily suffers from dirt (silicon) pulmoary occupation disease.According to relevant statistics, coal in China industry causes the improper personnel reduction of practitioner even many than the improper personnel reduction caused due to severe and great casualty such as gas explosion, roof fall, floods due to dust pollution; And the dust concentration that China's bolt-spary supports operation produces is also considerably beyond the dust concentration of mining and driving face produces.
What underground mine use concrete sprayer all adopted is that wind send concrete mode, and all adopts dry type (or tidal) wind to send technique.Thus, jetting material not only very easily produces dust, and very high concentrations, and not only grievous injury miner's is healthy, and working environment dust fills the air, extremely badly.Due to intrusion and the severe operating mode of existing equipment press seal face abrasive material, pulp shooting machine sealing plate well damage, belongs to and very easily damages accessory, and not only leak out generation dust, and maintenance is frequent, costly.
The power source of current concrete pump is motor or diesel-driven oil pump systems substantially.This dynamical system integrated level is high, is convenient to move integrally, is applicable to field work, and just inapplicable for underground coal mine.Coal mine down-hole tunnel narrow space, high, the bulky integral device of integrated level both cannot be laid, and was also not easy to the condition of work of mining face under mine moved by hand.
In recent years, along with the fast development of coal industry, the incidence of disease of minimizing miner pneumoconiosis and occupational health hygienic issues have caused the great attention of leaders and authorities, and the dust concentration significantly reducing working site is then the fundamental solution of dealing with problems.
