Description
Technical field
The utility model belongs to two pairs of rollers roller corollary equipment field, and in particular to a kind of two pairs of rollers roller high-low pressure nitrogen
Purge protection device.
Background technology
In tungsten carbide powder manufacturing field, carbon dust and tungsten powder need to carry out carbonization technique after the mixing is complete, mainly by powder
End loads graphite boat, is then fed into carbide furnace carbonization.Before carbide furnace is sent into, can carry out artificial or mechanical simple pressure boat with
Increase boat charge.In pressure boat, this link introduces the present apparatus, is carried out forcing pressure boat with the mode of two pairs of rollers, significantly increased
Boat charge.But two pairs of rollers roll occur tungsten powder temperature raise, for tungsten powder meet oxygen easily occur oxidative phenomena from
And carbonization effect is influenceed, so to be filled with protective gas nitrogen so as to reach protecting effect.
Boat charge this link of improving domestic at present is all with pressure boat machine, is obvious the shortcomings that this mode：
The exposed oxidation easy in atmosphere of powder；Carbon dust and tungsten powder uniformity are very poor after compacting；Dust is huge in compacting process both wasted
Working environment is polluted again.
Utility model content
The purpose of this utility model is to provide a kind of structure novelty, the two pairs of rollers roller high-low pressure nitrogen purging of practical function
Protection device.
Technical scheme provided by the utility model is：A kind of two pairs of rollers roller high-low pressure nitrogen purges protection device, bag

Low-pressure nitrogen entrance, the second low-pressure nitrogen entrance is additionally provided with the double roller rolling body.
It is described to be internally provided with filter bag in the dust recycling mechanism as a kind of improvement of the present utility model, described
Collecting box is provided with below filter bag.
As a kind of improvement of the present utility model, high pressure nitrogen magnetic valve is additionally provided with the high pressure nitrogen entrance.
As a kind of improvement of the present utility model, the first low-pressure nitrogen is additionally provided with the first low-pressure nitrogen entrance
Magnetic valve.
As a kind of improvement of the present utility model, the second low-pressure nitrogen is additionally provided with the second low-pressure nitrogen entrance
Magnetic valve.
Beneficial effect：
Nitrogen is passed through by corresponding high and low pressure nitrogen inlet, the charging, blanking and two pairs of rollers for squeezing away roller roller roll
Air in the overall process closed cavities such as discharging, so as to effectively be completely cut off protection；Meanwhile in charging aperture high pressure introduced below
Nitrogen, additionally it is possible to purge powder, reduce the problem of powder glues wall；And can suitably it be adjusted by controlling corresponding magnetic valve
Whole purging frequency and time, further ensure also is provided product quality while reaching the demand of production technology；
In purge, in order to reduce production risk and improve working environment, dust recycling mechanism, the powder kicked up are set
Dirt enters the mechanism, and after the in-house sock filtration, gas safety discharge, dust falls along filter bag enters collecting box,
It is environment friendliness.
