Abstract

The invention provides a closed-loop type air conveying system for powder. The air conveying system comprises a fan and a powder inlet. The fan blows the powder entering from the powder inlet into a conveying pipe, and then the powder reaches a powder bin. An air return pipe is arranged between the fan and the powder bin. Compared with a traditional product, mixed gas separated from the powder bin can be conveyed into an air return system again and reused, and can not be exhausted out of the system, harm to the human body is avoided, and the closed-loop type powder air supply system is more environmentally friendly.

Description

Closed loop powder blast system
Technical field
The present invention relates to a kind of closed loop powder blast system of environmental protection.
Background technology
Powder delivery system of the prior art generally all comprises blower fan, powder entrance, the powder that blower fan enters powder entrance is blown into delivery pipe, then arrive filler bin, powder delivery system of the prior art free-falling body above filler bin enters filler bin, and the cyclone of separation bin top is directly got rid of the miscellaneous gas that contains fine particle from exhausr port, to atmosphere, pollute, not environmental protection, and dust is harmful, and cause certain waste.
Summary of the invention
The object of the invention is: the closed loop powder blast system that a kind of environmental protection is provided.
The technical scheme of blast system of the present invention is: a kind of powder blast system, and it comprises blower fan, powder entrance, the powder that blower fan enters powder entrance is blown into delivery pipe, then arrives filler bin, between blower fan and filler bin, backwind tube is set.
Optimally, at the uniform velocity distributing box is set between powder entrance and blower fan.
Optimally, blower fan is set to high pressure positive blower.
Optimally, delivery pipe is connected with filler bin by cyclone with backwind tube.
Between the technical program blower fan and filler bin, backwind tube is set, compares traditional product, the miscellaneous gas of separating again can be transmitted back in blast system and utilize in filler bin, can not discharge system outside human body is worked the mischief, environmental protection more.
At the uniform velocity distributing box is set between the technical program powder entrance and blower fan, can makes system operation more stable the delivery pipe that is assigned to of powder uniform and stable, actv. stops the generation of stopping up.
The technical program blower fan is set to high pressure positive blower, and power is sufficient, and system run all right is improved, and prevents that powder from stopping up.
The technical program delivery pipe is connected with filler bin by cyclone with backwind tube, and whole process is carried out under enclosed environment, has improved work efficiency, has reduced discharge of poisonous waste, has improved the feature of environmental protection.

Description of reference numerals:
1-filler bin; 2-cyclone; 3-delivery pipe; 4-backwind tube; 5-powder entrance; 6-is distributing box at the uniform velocity; 7-high pressure positive blower.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
As shown in the figure, the technical scheme of blast system of the present invention is: a kind of powder blast system, and it comprises blower fan, powder entrance, the powder that blower fan enters powder entrance is blown into delivery pipe, then arrives filler bin, between blower fan and filler bin, backwind tube is set; At the uniform velocity distributing box 6 is set between powder entrance and blower fan; Blower fan is set to high pressure positive blower.Delivery pipe 3 is connected with filler bin by cyclone 2 with backwind tube 4.
Powder enters at the uniform velocity distributing box 6 by powder entrance 5 and falls within delivery pipe 3, under high pressure positive blower 7 effects, powder enters cyclone 2 by delivery pipe 3, powder and mixing air are carried out to the separated of gas and powder, powder falls into filler bin 1, gas enters high pressure positive blower 7 by the exhausr port of cyclone 2 by backwind tube 4, forms closed loop powder delivery system.
