Abstract
The utility model relates to a nitrogen protection device for a TPA (Tissue Plasmogen Activator) feed bin. The nitrogen protection device comprises a feed bin (1), wherein a feed hopper (2) is connected above the feed bin (1), the nitrogen protection device is characterized in that nitrogen input tubes (3) are connected with the bottoms of the feed bin (1) and the feed hopper (2), an emptying tube (4) is connected at the top of the feed bin (1), and an emptying valve (5) is arranged on the emptying tube (4). In the nitrogen protection device, the nitrogen input tubes are connected with the bottoms of the feed bin and the feed hopper, when the nitrogen protection device is in operation, nitrogen can be input, air in the feed bin can be effectively discharged, accidents caused by sparks due to statics can be avoided, and the use safety is ensured.
Description
Technical field
The utility model relates to a kind of TPA feeding bin, relates in particular to a kind of TPA feeding bin nitrogen protection 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 the process that adds 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; Therefore make the air content in the TPA feeding bin reduce as much as possible, can effectively guarantee safe in utilization.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of and can guarantee TPA feeding bin nitrogen protection device safe in utilization.
The purpose of the utility model is achieved in that a kind of TPA feeding bin nitrogen protection device; Comprise feeding bin; Said feeding bin top is connected with cast hopper; The bottom of said feeding bin and cast hopper is connected with the nitrogen input pipe, and the top of said feeding bin is connected with blow-down pipe, and said blow-down pipe is provided with atmospheric valve.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is connected with the nitrogen input pipe in the bottom of feeding bin and cast hopper, and input nitrogen can effectively be got rid of the air in the feeding bin during running, avoids the generation of static electricity spark, leads to a disaster, and has guaranteed safe in utilization.
