Abstract

The utility model relates to an apparatus for reclaiming powder in the material charging of PTA polyester, which is provided with a sealing box body and a blower, wherein the box body is split into an upper box body, a middle box body and a lower box body; a spraying and blowing pipe and a filtering bag mouth are arranged in the upper box body; a net gas outlet is arranged on the upper box body, and is connected with the blower by an exhaust pipe; a pulse valve is arranged at the outside of the upper box body, and is connected with the spraying and blowing pipe; a filtering bag body is arranged in the middle box body, and is fixedly connected with the filtering bag mouth by a quickly fixing ring; a dust gas inlet which is externally tangent to the middle box body is arranged in the middle box body; a powder reclaiming valve is arranged at the bottom of the lower box body. The utility model reclaims raw material which is scattered and exhausted outward form a material charging mouth, improves the working environment, enables the physical and mental health of operators for producing polyester chips to obtain guarantee, and removes the hidden dangers of dust explosion.

Description

The PTA polyester loose powder retracting device that feeds intake

Technical field

The utility model relates to a kind of PTA polyester loose powder retracting device that feeds intake.

Background technology

Polyester slice production dog-house in the process of feeding intake has a certain amount of dust diffusion and emerges from airduct with air-flow, causes operating environment very abominable, very likely produces the gas dust explosion when dust concentration reaches certain value in the air.The dust of discharging in the airduct has polluted environment on the one hand, has also caused the loss of a small amount of raw material on the other hand.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of dog-house that is arranged on, and can improve production environment, solves environmental pollution, can regain diffusion again and the PTA polyester of the raw material that the effluxes loose powder retracting device that feeds intake.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of PTA polyester loose powder retracting device that feeds intake, have airtight casing and blower fan, casing is divided into upper box, middle casing and lower box, be provided with winding-up pipe and filter pocket mouths in the upper box, upper box is provided with the pure qi (oxygen) outlet, the pure qi (oxygen) outlet links to each other with blower fan by exhaust column, upper box is outside equipped with pulse valve, pulse valve links to each other with the winding-up pipe, be provided with the filter bag body in the middle casing, the filter bag body is fixedlyed connected by the fast-assembling ring with sack, and middle casing is provided with and the external dirt gas import of cutting of raising middle flask, and the lower box bottom is provided with reclaims the powder valve.

Safe and reliable to operation for guaranteeing equipment, also be provided with explosion venting valve on the described middle casing.

The beneficial effects of the utility model are, the PTA polyester of the present utility model raw material that the loose powder retracting device has reclaimed the dog-house diffusion and effluxed that feeds intake has improved working environment, and polyester slice production exercise workmanship's physical and mental health is protected, and removes dust explosion hidden danger.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the feed intake structural representation of loose powder retracting device of PTA polyester of the present utility model.

Fig. 2 is the left view of Fig. 1.

Among the figure: 1. casing, 11. upper boxes, the outlet of 111. pure qi (oxygen)s, casing in 12., 121. dirt gas imports, 13. lower boxes, 2. blower fan, 3. winding-up pipe, 4. exhaust column, 5. pulse valve, 6. filter bag body, 7. explosion venting valve 8. reclaims the powder valve.

The specific embodiment

As Fig. 1, PTA polyester of the present utility model shown in the 2 loose powder retracting device that feeds intake, have airtight casing 1 and blower fan 2, casing 1 is divided into upper box 11, middle casing 12 and lower box 13, be provided with winding-up pipe 3 and filter pocket mouths in the upper box 11, upper box 11 is provided with pure qi (oxygen) outlet 111, pure qi (oxygen) outlet 111 links to each other with blower fan 2 by exhaust column 4, upper box 11 is outside equipped with pulse valve 5, pulse valve 5 links to each other with winding-up pipe 3, be provided with filter bag body 6 in the middle casing 12, filter bag body 6 is fixedlyed connected by the fast-assembling ring with sack, and middle casing 12 is provided with dirt gas import 121 and the explosion venting valve 7 circumscribed with middle casing 12, and lower box 13 bottoms are provided with reclaims powder valve 8.

Blower fan 2 is selected explosive-proof grade dIIBT4 for use, the blower fan of degree of protection IP54, the blast of blower fan 2 is selected to make system be in range of negative pressure, guarantee that dog-house does not have the dust of overflowing, dirt gas import 121 and middle casing 12 are circumscribed, casing 12 during the dusty gas that is filtered enters along tangent line, partial material is tangentially by sedimentation, to reduce the load of filter bag body 6, partial material is adsorbed on the filter bag body 6, during deashing, the deashing air-flow of pulse valve 5 ejection is full of whole box body 1, makes upper box 11 and the filter bag body that is attached thereto 6 is inner produces certain malleation, amasss in the vibration because of the bag wall of the dust on filter bag body 6 surfaces to come off, when amass in lower box 13 powder more for a long time, discharge lower boxes 13 by reclaiming powder valve 8.
