Technical Field

The utility model belongs to the technical field of the technique of PVC membrane production facility and specifically relates to a PVC dust recovery device is related to.

Background

At present, the lamp box cloth is usually made of a lamp box signboard fabric which is composed of two layers of PVC and a layer of high-strength grid cloth, and is also called as Baoli cloth. The method comprises two types of inner polishing and outer polishing, and the main production methods comprise a knife blade coating method, a rolling method and a pasting method. The calendering process includes mixing PVC powder, liquid plasticizer and other material, hot rolling to form PVC film, and adhering the PVC film and the base cloth via the pressure of high pressure hot roller to form one integral. The light-emitting diode has the characteristics of better surface flatness, uniform light transmission and better advantage on inner lighting lamp cloth. The common lamp boxes on the market at present are made of lamp box cloth by adopting a calendering method.

In the production process of the PVC film, PVC powder needs to be injected into the stirring device first to be mixed with other auxiliary materials. PVC dust is usually adorned in the material bag, is provided with hoisting accessory at agitating unit upside, and the PVC dust in the material bag of hoisting again pours into agitating unit into from agitating unit's feed inlet department. In the process of pouring into, the phenomenon of raising can appear inevitably in the PVC dust, and the PVC dust is comparatively tiny, when the PVC dust floats in the air, causes the pollution to operational environment on the one hand, is inhaled the lung by the workman easily in, influences workman's physical and mental health, and on the other hand can lead to the waste of PVC dust, has increased manufacturing cost.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a PVC dust recovery device, it can be retrieved the PVC dust of being raised of agitating unit feed inlet department, has reduced manufacturing cost, and has reduced the pollution that causes operational environment, fine protection workman's physical and mental health.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

the utility model provides a PVC dust recovery device, includes updraft ventilator and recovery separator, updraft ventilator include the exhaust column, the one end of exhaust column is the suction opening, recovery separator include the dust bin, go out the tuber pipe, air-blower and exhaust stack, the one end that the suction opening was kept away from to the exhaust column is connected to the dust bin, be connected with out the tuber pipe on the lateral wall of dust bin, go out the other end of tuber pipe and the air intake connection of air-blower, the air outlet and the one end of exhaust stack of air-blower are connected, exhaust stack's the other end is the air exit, fixed mounting has filter assembly in the dust bin, filter assembly is connected with the position department that the tuber pipe was gone out with the dust bin and is connected with the position of exhaust column and separate completely, be provided.

Through adopting above-mentioned technical scheme, through setting up the suction opening in the exhaust column at agitating unit's feed inlet department, later start the air-blower, the air-blower is continuous with gas from the air intake air inlet air outlet department of blowing into.
