The existing mixer hopper structure is relatively conventional. When adding powdered materials, it is easy to generate a lot of dust, which affects the processing environment. The Chinese patent application with application number CN202220332626.2 discloses a dust-proof feeding hopper for sodium bisulfite processing. A flexible opening discharge baffle is set at the top of the funnel to realize automatic adjustment of the size of the mouth and effectively prevent the material from flying. However, the design still has the following defects in actual application:

By improving the feeding hopper 2 of the existing sodium bisulfite processing stirring equipment, a dust-proof feeding component is arranged on the top of the feeding hopper 2 to realize the closed feeding of the sodium bisulfite powder raw material, effectively prevent the material from flying, and cooperate with the rotary material dial to intermittently control the raw material feeding, which can effectively avoid the impact pressure on the lower equipment when a large amount of material is fed instantly. A fixed-speed feeding structure is arranged at the bottom of the feeding hopper 2. The fixed-speed feeding structure is used to uniformly, continuously and controllably feed the sodium bisulfite powder raw material in the feeding hopper 2 into the stirring equipment, effectively ensuring the production operation efficiency. The entire feeding process can effectively reduce the occurrence of dust dispersion, greatly improving the quality of the working environment.

[0021] In the specific implementation process, the above-mentioned rotary material-discharging component includes a fixed shaft 7, a fixed sleeve 8 and a material-discharging baffle 9. The middle part of the feed hopper 5 is an arc cavity with a symmetrical structure. The size of the arc cavity matches the rotary material-discharging component. The fixed shaft 7 is rotatably inserted into the feed hopper 5 and one end is connected to the output end of the driving component. The fixed sleeve 8 is sleeved on the fixed shaft 7, and the material-discharging baffle 9 is welded on the fixed sleeve 8 along a circular array. When in use, the driving component is started, and the driving component is used to drive the fixed shaft 7 and the fixed sleeve 8 on the fixed shaft 7 and the material-discharging baffle 9 to rotate synchronously. During the rotation process, under the cooperation of the material-discharging baffle 9 and the internal cavity in the feed, intermittent feeding of raw material powder is realized, which can effectively reduce the pressure of the lower equipment and avoid the blockage of the lower feeding hopper 2 caused by a large amount of concentrated feeding.
