Dust Capacity.
The utility model is further arranged to：The flexible pipe outlet of the dust catcher is arranged with dust-separation bag.
By using above-mentioned technical proposal, dust-separation bag is set, to the gas entered inside dust catcher from flexible pipe, enters to advance
The filtering of one step.
The utility model is further arranged to：The hard tube is connected with vacuum table.
By using above-mentioned technical proposal, vacuum table is set, when negative pressure does not reach standard, so that operating personnel can be fast
Speed is observed, so as to make corresponding measure.
The utility model is further arranged to：The tank is provided with audible-visual annunciator, the tank and set
It is equipped with the water level switch for controlling audible-visual annunciator.
By using above-mentioned technical proposal, audible-visual annunciator is set, and installs to control acousto-optic report in tank
The water level switch of alert device, when water level is too low in tank, then water level switch will control audible-visual annunciator to send alarm signal
Number, remind operating personnel's addition water.
In summary, the utility model has the advantages that：
First, in the side wall connection shower of blast pipe, shower is connected by shower nozzle with blast pipe, shower is to from suction
The gas containing dust that dirt device is come out by emission by exhaust pipe carries out spray dust, so as to effectively purify from blast pipe row
The gas of air inlet is put, while check valve is set in blast pipe, to avoid the water sprayed into blast pipe from flowing into dust catcher；
Second, installing the small sieve of a sieve aperture than analysis sieve between the air flow inlet and air stream outlet of cyclone cylinder upper end
Plate, and dust-separation bag is arranged in the outlet of flexible pipe, so as to further be filtered to gas, to reduce the powder into dust catcher
Dirt.
