Device and method for uniformly mixing scattered fine powder

Abstract

The invention relates to a material mixing device and method and in particular relates to a device and a method for uniformly mixing scattered fine powder, belonging to the field of mechanical equipment. The device comprises a feeding device, a dust remover, a spiral discharging device and a continuous discharging mixer, wherein the feeding device comprises a storage tank, a radio frequency vacuum generator, a collection bin and a cyclone separator; the radio frequency vacuum generator is positioned on the upper part of the collection bin. According to the invention, a mixing operation is performed in a mode of alternatively combining inclined shovel tools and hollow arrow tools in the mixer, and mixed materials are high in uniformity. The device is also applied to sticky materials, and the problem of dead angle in the mixing process is solved. The mixing tools are divided into two kinds, wherein one kind of mixing tools have an inclined angle, materials are pushed to move forwards while being stirred, and the continuous discharging aim is further achieved.

Description

technical field [0001] The invention relates to a material mixing device and method, in particular to a uniform mixing device and method for fine powder material, which belongs to the field of mechanical equipment. Background technique [0002] Sludge ceramsite is made by firing sludge after a series of processes. Because ceramsite has excellent characteristics such as chemical stability, heat resistance, large specific surface area, light weight, and thermal shock resistance, it is used in chemical industry, It is widely used in many fields such as construction and petroleum. The mixing process before sludge ceramsite molding uses sludge, fly ash, and river sediment (or shale) as raw materials. The above three fine powders are wastes generated during sewage treatment, and have sticky. The use of these three kinds of waste in the production of ceramsite can make waste reuse and save resources. [0003] The mixer in the mixing process is widely used in chemical industry, e...

AI Technical Summary

Problems solved by technology

In production, oscillating mixing is the most widely used, and the technology is relatively mature, but the machine occupies a large area, and there are still problems such as uneven mixing and dead ends in the actual application process.

[0004] For the feeding technology of the mixer, the spiral or pneumatic method is mostly used, but the conveying effect is poor for viscous materials such as sludge. During the conveying process, the pipeline is blocked, which hinders the normal conveying work.

At the same time, the dust generated by the transportation is also more, resulting in a bad working environment, and when the dust concentration reaches a certain range, explosions are prone to occur
