A high-efficiency and energy-saving straw powder drying device

Abstract

The invention discloses a high-efficiency and energy-saving straw powder drying device, which belongs to the field of drying devices. By improving the existing drying device, the drying effect of the straw powder after moisture absorption and moisture change is effectively improved. One separates the sticky and powdered straw, so that the powder and the sticky block enter the drying pipe one and the drying pipe two respectively, so that targeted drying can be carried out. In the second, the splitter plate and the speed retarder are set respectively, so that the splitter plate increases the contact area between the powder and the hot air, and the retarder delays the falling speed of the cohesive block to prolong the drying time, thereby effectively improving the drying effect and drying. At the same time, the cohesive block is separated from the powder, which saves the trouble of screening. In addition, the first drying pipe and the second drying pipe are connected to each other, so that the hot air can be recycled, which can effectively save energy consumption and reduce dust effectively. generation.

Description

technical field [0001] The invention relates to the field of drying devices, in particular to a high-efficiency and energy-saving straw powder drying device. Background technique [0002] Every year during summer harvest and autumn and winter, a large amount of wheat, corn and other stalks are always burned in the fields, producing a lot of thick smoke, which not only becomes the bottleneck of rural environmental protection, but even becomes the chief culprit that affects the urban environment. According to relevant statistics, my country, as a large agricultural country, can produce more than 700 million tons of straw every year, which becomes "waste" that is "not very useful" but must be disposed of. In this case, it is completely handled by the farmers, and a large number of burnings have occurred. [0003] The comprehensive utilization of straw has broad prospects. In practice, many places in our country have actively explored and creatively adopted many beneficial expe...

Problems solved by technology

[0004] When straw is used in papermaking, furniture, etc., it will be crushed first to be powdered for subsequent processing. However, straw powder will inevitably absorb moisture and form a cohesive block when stacked, so it will be dried before use. Currently, dry powder The best method is to use a conveyor belt to transport it to the drying box. Because the powder on the conveyor belt is difficult to spread out, it will cause incomplete drying, and it is not easy to screen out the cohesive lumps mixed in the powder.
