Abstract
The utility model relates to a plastic pneumatic local fan blower for mines. The utility model is composed of an air collecting hood, keys, an impeller, a cabinet, a pneumatic motor, a muffler blocking cover, joints, an air inlet pipe, bolts, gaskets, press plates, etc. The impeller is made of antistatic and flame-retarding engineering plastics in the mode of injection manufacture molding; detected by the national quality supervision inspection department, the impeller is in accordance with the use standard of underground mines. The utility model has the advantages of light weight of the complete machine and convenient operation and maintenance; a blower generates no electric sparks and friction sparks in the process of operation, the performance is stable, and the safety is high. The utility model is suitable for pumping or blowing ventilation in an underground high-concentration gas environment, and is a special device for treating mine spatial angle gas and local gas accumulation.
Description
This new practical being applicable to is done in the high concentration gas environment under the coal mine to extract out or the forced ventilation use.
At present, make the only Polish WLEP-600 that produces of country and the two control of the WLEP-800 type electricity-wind secondary fan of the pneumatic secondary fan of mining plastics of draught fan impeller abroad with engineering plastics, but price is expensive.The domestic pneumatic secondary fan of plastics that does not still have the colliery special use.
Along with developing rapidly of coal industry, the mechanization degree of colliery mining face under mine also improves constantly, and the down-hole ventilation system also becomes increasingly complex.Extract out or the forced ventilation problem in order to solve in high concentration gas under the coal mine (methane concentration the surpasses 1%) environment; processing stope corner gas and other local gas gather or transfinite; to guarantee that the colliery mining face under mine has the good working environment; the protection workman is healthy, guarantees safe production.So both at home and abroad the New-type local blower that development is used for mine all takes much count of.
The purpose of this utility model is that development is a kind ofly made blast fan with engineering plastics, drives the ventilating fan running by compressed air, and it is in light weight, safe and reliable to have a complete machine, the pneumatic secondary fan of mining plastics of characteristics such as practicality.
Technical parameter of the present utility model
The pneumatic secondary fan of mining plastics (is an atmospheric pressure 1.01325 * 10 in the standard condition
5Pa, air temperature+20 ℃, relative moisture 50%, air density 1.2kg/m
3) operation, when compressed-air actuated working pressure and flow reach the rating number scope of pneumatic motor, the aerodynamic quality parameter of blower fan is as follows:
Fan delivery 3.3m
3/ s(max)
The blower fan full blast is pressed: 980Pa(max)
Structure of the present utility model and characteristics
The pneumatic secondary fan of mining plastics is by wind-collection cover 1, axle head fixing bolt 2, packing ring 3,8,12,18, pressing plate 4, key 5, bolt 6,10,16, nut 7,11,17, impeller 9, casing 13, pneumatic motor 14, silencing apparatus 15, nameplate rivet 19, nameplate 20, blanking cover 21, joint 22, suction tude 23 grades are partly formed, and detailed construction as depicted in figs. 1 and 2.
