For example: Chinese patent 200820152012.6, a kind of airborne dust arrester of boom-type roadheader is disclosed, it mainly comprises suction port, and suction port is enclosed in around the development machine cutting head, and follow-up connection pipeline is supported on the machine body of boring machine.
Summary of the invention
The utility model for solve the existing airborne dust pelletizing system of boom-type roadheader exist integrated level poor, take up room big, operate inflexible problem, provide a kind of air channel to be arranged in the high-efficiency dust removal system at development machine middle part.
The utility model adopts following technical scheme to realize:
The air channel is arranged in the high-efficiency dust removal system at development machine middle part; Comprise air intake, air channel, deduster and blower fan; Air channel one end connects air intake, and the other end connects deduster, and deduster and blower fan are installed on the afterbody of development machine; It is characterized in that described air intake is arranged at the cutting units of development machine and the frame front end between the loading part, the air channel is built in central rack and is structure as a whole with frame.Pumping plant and fuel tank with development machine becomes one simultaneously, so that deduster is integrated.
The air intake place of the utility model is provided with guiding device; Guiding device comprises air intake top panel, air intake net sheet and the air intake lower panel that connects successively, and air intake top panel and air intake lower panel are cell structure, and the lower edge of the per pass grid that the air intake lower panel is inboard is provided with deflector; The installation direction of deflector is parallel to the air channel; The width of deflector is the width of grid, and being beneficial to intake airflow does not have suction air channel, eddy current ground, reduces flowing resistance.
Electric-control system of the utility model and operating system, electric-control system are integrated in the development machine electric control box, and operating system is integrated in the development machine control box.Dust removal operation belongs to the part of development machine operation, greatly facilitates development machine driver operation dust pelletizing system in the operation development machine.
The utility model places the development machine middle part with the air channel of dust arrester, is the part of development machine rack construction, has realized that the height of dust arrester and boom-type roadheader is integrated, and airborne dust arrester is an ingredient of boom-type roadheader simultaneously.
During work, at first dust laden air gets in the built-in fixedly air channel of development machine through the air intake of band guiding device, gets into then in the deduster, after deduster is handled, utilizes high-power centrifugal blower that the air of cleaning is discharged from outlet.
The relative prior art of the utility model has following beneficial effect: the utility model places the dust absorbing air passage of dust arrester in the boom-type roadheader central fuselage; Make airborne wet dust removal device and boom-type roadheader height integrated; Under the situation of cut sight line that does not influence the tunnel adaptive capacity of this machine, development machine driver and complete machine repair and maintenance, improved operator's working environment greatly.The utility model efficiency of dust collection can reach more than 90%, has largely improved the working environment of present driving face, can effectively control coal-dust explosion, promotes the safety in production in colliery greatly, further reduces the incidence of disease of colliery pneumoconiosis.Along with country and the attention of society to employment security, coal mining enterprise will more and more pay attention to the dust problem of getting working face, so, the utlity model has bigger market prospects.
