Embodiment Construction

[0011] With reference to the attached drawings, a powder shutter includes an organic casing 1. The upper end of the casing 1 is a feed inlet 2, and the lower end is a discharge opening 3. The two ends of the casing are equipped with a left end cover 4 and a right end cover 5. A rotating shaft 6 passes through the left end cover and the right end cover respectively. The casing 1 is provided with an impeller 7 slidably mounted on the rotating shaft 6. The right side of the impeller 7 is provided with an extension end 8, and the extension end 8 is provided with an annular groove 11, The rotating shaft 6 on the right side of the extension end 8 is threadedly connected with an adjusting nut 9. The rear end of the adjusting nut 9 has a clamping block 10 that can rotate in the annular groove. The clamping block 10 can rotate in the annular groove, and the adjusting nut 9 drives the impeller. 7 mobile. Transparent windows are opened on the side walls of the inlet and the outlet.

Abstract

The invention discloses a powder airlock which comprises a machine casing. The upper end of the machine casing is a material inlet, the lower end thereof is a material discharge opening, and both ends are provided with a left end cover and a right end cover. A rotary shaft respectively penetrates through the left end cover and the right end cover. An impeller which is glidingly arranged on the rotary shaft is arranged in the machine casing. The right side of the impeller is provided with an extension end, the interior of the extension end is provided with a clamping groove, and the rotary shaft on the right side of the extension end is connected with an adjusting nut by threads. The rear end of the adjusting nut is provided with a clamping block which is matched with the clamping groove. The adjusting nut drives the impeller to move. The rotary shaft is connected with the adjusting nut by the threads, the adjusting nut is rotated to drive the impeller to move along the rotary shaft, and then the invention realizes the accurate the functions proportioning and metering of different raw material, and has simple structure.

Description

Technical field [0001] The invention relates to a powder material unloading device, in particular to a powder material air shutter suitable for the fields of medicine, chemical industry, feed processing, food processing and the like. Background technique [0002] The air shutter is an important equipment in the pneumatic conveying and ventilation dust removal network. Its main function is to continuously discharge the materials in the unloader or dust collector in time, and at the same time prevent the outside air from entering the inclined feeder or dust collector. Existing air shutters mainly have two structures, "rotary valve centrifugal type" and "worm wheel propulsion type", and their working principles are similar. Both of them realize high-pressure gas sealing and decompression discharge through the rotation of blades. At present, there is no air shutter that can achieve the precise ratio of different raw materials in different proportions. Summary of the invention [0003...
