Spiral pump for pneumatic transmission

Abstract

The invention discloses a spiral pump for pneumatic transmission, which comprises a feeding box, a spiral shaft, a wear-resistant sleeve, a nozzle, a mixing box and a discharging box. The feeding box, the wear-resistant sleeve, the mixing box and the discharging box are communicated in order. The spiral shaft penetrates a space formed by the feeding box and the wear-resistant sleeve in order, and two ends of the spiral shaft can rotate around the self-axis through a bearing; and the mixing box is connected with the nozzle. After entering the feeding box, powdery materials pass through the wear-resistant sleeve from the feeding box along a screw of the spiral shaft, finally the powdery materials are brought into the mixing box. After the materials are discharged into the mixing box, compressed air is injected into the mixing box through the nozzle, so that the materials are fully fluidized, and then the fluidized materials are conveyed to a conveying pipeline which is connected with the end part of the mixing box. In the whole conveying process, the spiral shaft can uniformly convey the materials from the feeding box to the mixing box, so that the materials in the mixing box can be fully fluidized, and finally the materials smoothly pass through the conveying pipeline.

Description

technical field [0001] The invention relates to a screw pump for pneumatic conveying of zinc oxide. Background technique [0002] Pneumatic conveying, also known as airflow conveying, mainly uses the energy of airflow to transport granular materials along the direction of airflow in a closed pipeline, which is a specific application of fluidization technology. The pneumatic conveying device has a simple structure and is easy to operate. It can be used for horizontal, vertical or inclined conveying. During the conveying process, it can also perform physical operations such as heating, cooling, drying and air classification of materials or certain chemical operations. [0003] In the prior art, the warehouse pump pneumatic conveying device first fills the material into the pressure vessel, and then fills the airtight pressure vessel with compressed air, so that the air and the material are pressed into the pipeline together for transportation. When feeding with the warehouse ...

AI Technical Summary

Problems solved by technology

When feeding with the warehouse pump pneumatic conveying device, it is often difficult to convey or the material blocks the pipeline, mainly because the feeding amount is not easy to control and the output is uneven; in addition, due to the high concentration of the conveyed material, Therefore, the conveying speed is slow. Some materials with their own viscous characteristics may stick to the inner wall of the pipeline during the conveying process, and accumulate more and more, which eventually leads to poor conveying of the materials during the conveying process.
