A powder feeding device

Abstract

The invention discloses a powder pouring device comprising a pressing mechanism, a turnover mechanism and a double-ring sealing mechanism. The pressing mechanism is used for fixing a material tank sothat an opening of the material tank can be connected with a material pouring inlet of the turnover mechanism. A material pouring outlet of the turnover mechanism is connected with a material outlet.The double-ring sealing mechanism is used for preventing pollution atmospheres of hot chambers on the two sides of the material outlet from being mixed with each other. The powder pouring device has the beneficial effects that by means of the powder pouring device, long-distance operation can be achieved and mutual mixing of toxic atmospheres can be controlled; by means of the turnover mechanism and the pressing mechanism, connecting and material pouring of the material tank and the material pouring device are achieved, it can be ensured that products can be accurately fed into a feeding tank,and the possibility that pollution materials are scattered outside the feeding tank is reduced; and meanwhile, by means of the double-ring sealing mechanism, it can be avoided that the pollution atmospheres are mixed between the hot chambers.

Description

technical field [0001] The invention belongs to the technical field of radioactive powder inversion, and in particular relates to an automatic powder inversion device. Background technique [0002] In the field of nuclear chemical industry, it is necessary to flip the nuclear fuel and transfer it to the charging tank from the roasting process. The powder is highly radioactive and must be poured in a hot chamber. In the past projects, container I and container II are usually directly sealed and docked, and the two containers are turned over by the motor to drive the gear to realize the unloading. Although the device occupies a small area and is easy to operate, it is easy to cause pollution in the hot chamber when the two containers are separated. [0003] Therefore, in order to prevent the powder from being scattered in the hot chamber during the inversion process and contaminating the hot chamber, it is necessary to develop a material dumping device that can be operated r...

Although the device occupies a small area and is easy to operate, when the two containers are separated, it is easy to cause pollution in the hot chamber

[0003] Therefore, in order to prevent the powder from being scattered in the hot chamber during the inversion process and contaminate the hot chamber, it is necessary to develop a material dumping device that can be operated remotely to control the exchange of radioactive atmospheres.
