The vacuum unit also includes vacuum system pressure control device, air draught shell side be provided with pressure vacuum gauge and
Pressure sensor device, lead at the air draught housing outlet on the connecting line of vavuum pump and be provided with automatic regulating valve.
The agitating device includes agitating shaft and motor, is adjusted at the top of the agitating shaft through bung outside with variable ratio frequency changer
The motor of rotating speed is connected, and shaft bottom is located in discharging opening, and agitating shaft bottom is provided with helical form agitating paddle.
The aggregate bin can be set to the staving of double-deck jacketed, and the chuck bottom of staving side is provided with the entrance of low-temperature receiver, with
Cold source equipment outlet connection is circulated, opposite side chuck top exports provided with low-temperature receiver, is connected with the entrance for circulating cold source equipment.
Feeding dust arrester of the present utility model can monitor vacuum in bucket in real time and be automatically adjusted by regulating valve true
Pneumatics power, it can preferably control charging rate；The carbon block filter of use can not only improve dust removing effects and efficiency, simultaneously
The smooth easy cleaning in surface, convenient recycling；Staving may be configured as jacket type, by introducing circulation low-temperature receiver into chuck, reduce
The adhesion blockage problem of material.
Brief description of the drawings
Fig. 1 is the structural representation of feeding dust arrester.
Embodiment
In order to preferably illustrate structure and content of the present utility model, it is carried out further in conjunction with embodiment and accompanying drawing
Illustrate, but embodiment is only better embodiment of the present utility model, all spies described according to the utility model patent application range
The equivalence changes that sign and principle are done, in the scope of protection of the utility model.
As shown in figure 1, feeding dust arrester of the present utility model includes aggregate bin（1）, vacuum unit（2）And dedusting
