Abstract
The utility model provides a technical solution of purification dust removing device for a tunneling machine of coal mine, the dust removing device of the utility model comprises a rotary dust suction opening which is fixed to a power head of the tunneling machine; the dust suction opening is communicated with a fixed air duct; the fixed air duct is connected with a pressure-resistant air duct through a telescopic air duct; the pressure-resistant air duct is connected with one end of an air inlet of one ventilator; the other end of the ventilator is provided with a dust remover; the dust remover is connected with a filtering muffler; A dust outlet is provided below the filtering muffler. The dust removing device of the technical solution has the following advantages: simple structure, high dust suction rate, capacity for removing the coal dust in time, and prevention of coal dust pollution on the working face of tunneling.
Description
Technical field:
The utility model relates to a kind of dust arrester, especially a kind of coal mine development machine purifying and dedusting device.
Background technology:
In the prior art, technique known is that development machine will produce a large amount of coal dusts in cutting, loading, transport process, spreading of coal dust, hide some dangers for for the underground work in colliery, the development machine that use in present domestic colliery is typically equipped with external spraying and inner sprayer unit, but plug nozzle often appears in use, problem such as water seal is fragile, external spraying uses reluctantly, internal spraying is owing to safeguard relatively difficulty, use a period of time after, nearly all throw aside.This is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of technical scheme of coal mine development machine purifying and dedusting device is provided, and the apparatus structure of this scheme is simple, the dust-absorbing rate height.
This programme is realized by following technical measures: a kind of coal mine development machine purifying and dedusting device, the characteristics of this programme are: comprise the rotation suction port that is fixed on the development machine unit head, suction port is communicated with fixing air duct, described fixedly air duct is connected with withstand voltage air duct by Telescopic air duct, withstand voltage air duct is connected with an end of the air intake of a ventilation fan, the other end of ventilation fan is provided with deduster, and deduster is connected with filtering silencer, and the below of described filtering silencer is provided with dirt-discherging outlet.Withstand voltage air duct is the withstand voltage air duct of resin.Ventilation fan is the explosion-proof propeller fan of pull-out type.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because the rotation suction port that is fixed on the development machine unit head is arranged in this scheme, the coal dust that produces in the tunneling machine cutting process in time can be siphoned away, fixedly air duct has been connected the explosion-proof propeller fan of rotation suction port and pull-out type with Telescopic air duct, the explosion-proof propeller fan of pull-out type sucks coal dust, through deduster, behind the filtering silencer, flowing to conveyer belt with water through dirt-discherging outlet exports in the lump with coal, clean air is discharged from filtering silencer, this shows, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment.
Among the figure, 1 is the rotation suction port, and 2 are fixing air duct, and 3 is Telescopic air duct, and 4 is withstand voltage air duct, and 5 is ventilation fan, and 6 is deduster, and 7 is filtering silencer, and 8 is dirt-discherging outlet.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the coal mine development machine purifying and dedusting device of this programme, the characteristics of this programme are: comprise the rotation suction port 1 that is fixed on the development machine unit head, suction port 1 is communicated with fixing air duct 2, described fixedly air duct 2 is connected with withstand voltage air duct 4 by Telescopic air duct 3, withstand voltage air duct 4 is connected with an end of the air intake of a ventilation fan 5, the other end of ventilation fan 5 is provided with deduster 6, deduster 6 is connected with filtering silencer 7, and the below of described filtering silencer 7 is provided with dirt-discherging outlet 8.Withstand voltage air duct 4 is the withstand voltage air duct of resin.Ventilation fan 5 is the explosion-proof propeller fan of pull-out type.During work, the air that has coal dust is under the suction of ventilation fan 5, through rotation suction port 1, fixedly air duct 2, Telescopic air duct 3, enter ventilation fan 5, through becoming clean air behind deduster 6, the filtering silencer 7, the sewage that has coal dust flows out from dirt-discherging outlet 8, is output with coal.
