Abstract
The utility model relates to a TPA throws material device, including feeding bin (1), feeding bin (1) top is connected with batch hopper (2), the top of feeding bin (1) is connected with blow-down pipe (5), its characterized in that batch hopper (2) are connected with static earth connection (3), the bottom of feeding bin (1) and batch hopper (2) is connected with nitrogen gas input tube (4), be equipped with atmospheric valve (6) and filter (7) on blow-down pipe (5) in proper order. The utility model discloses the feeding hopper is connected with the static earth connection, the derivation of favourable static, the discharge of the favourable air of the nitrogen gas input tube of the bottom of feeding storehouse and feeding hopper, and the rear of atmospheric valve is equipped with the filter, can prevent that the dust from discharging in the air, reduces environmental pollution, also can retrieve the reuse dust simultaneously, reaches energy-concerving and environment-protective safe advantage on the whole.
Description
Technical field
The utility model relates to a kind of TPA charging device, belongs to the chemical industry equipment field.
Background technology
In producing the polyester process, terephthalic acid (TPA) (TPA) is one of main material, because the TPA that throws in is Powdered; In adding the process of cast hopper, can produce static, and static runs into air and may produce spark, possibly set off an explosion or fire when serious; For fear of this type of accident, make that the air content in the TPA feeding bin reduces as much as possible, can effectively guarantee safe in utilization; Therefore be provided with evacuated tube at the top of feeding bin, in time get rid of air in the storehouse, evacuated tube is taken a certain amount of TPA dust easily out of in discharged air in feeding bin; Cause waste to a certain extent, and polluted environment.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of and can reclaim dust, reduces pollution and guarantee TPA charging device safe in utilization.
The purpose of the utility model is achieved in that a kind of TPA charging device; Comprise feeding bin; Said feeding bin top is connected with cast hopper, and the top of said feeding bin is connected with blow-down pipe, and said cast hopper is connected with static ground wire; The bottom of said feeding bin and cast hopper is connected with the nitrogen input pipe, is provided with atmospheric valve and filter on the said blow-down pipe successively.
Compared with prior art, the beneficial effect of the utility model is:
The utility model cast hopper is connected with static ground wire; The derivation of favourable static, the discharge of the favourable air of nitrogen input pipe of the bottom of feeding bin and cast hopper, the rear of atmospheric valve is provided with filter; Can prevent that dust emission is in air; Reduce environmental pollution, also can recycle and reuse dust simultaneously, reach the advantage of energy-conserving and environment-protective safety on the whole.
