Description

Technical Field

[0001] The utility model relates to the technical field of closed feeders, in particular to a closed feeder used in a closed reaction system. Background Art

[0002] In industrial production, especially chemical production, the feeding of raw materials is usually achieved by screw feeders, but it is impossible to achieve closed feeding. In many occasions of chemical production, this requirement is often needed. For example, during the feeding process, a large amount of flammable and explosive gases, water vapor, etc. are generated in the reactor. If the feeding process cannot be carried out in a closed manner, these gases will overflow from the feeding port, corrode equipment, pollute the environment or affect the materials.

[0004] The above-mentioned closed feeder adopts two feed bins to solve the problem that the closed feeding device cannot achieve uniform feeding and the sealing effect is single. However, the ball valve adopts a purge fan and a shut-off fan for closed operation, and then uses multiple fan equipment structures, which increases the working cost of the closed feeder and reduces the practicality of the closed feeder. At the same time, the material is transported by rotating blades in the feed bin, so that the inner wall structure of the upper end of the feed layer is single, which leads to accumulation or blockage of materials during transportation, reducing the working use of the overall equipment of the closed feeder.
