[0012] Beneficial Effects

[0013] The utility model provides a dust removal device for buckwheat flour processing, which has the following beneficial effects:

[0031] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0032] Embodiment: During the production process, air containing buckwheat dust first enters the filter box 8 through the air inlet pipe 9, and the air needs to be initially filtered through the conical filter 10 before entering the shell 1. The design of the conical filter 10 helps to guide the airflow, while using its surface to capture larger particles. The first cleaning brush 13 on the shaft 11 rotates with the main shaft 15 driven by the motor 14, and regularly brushes the surface of the conical filter 10 to prevent dust accumulation and maintain good air permeability. The air that has been initially filtered through the conical filter 10 then enters the shell 1. At this time, the dust-containing gas needs to pass through the area covered with dust bags 5. These bags have a fine filtering structure that can capture smaller dust particles, and the clean air passes through the exhaust port on the partition 3 and is drawn out by the dust removal fan 7 through the exhaust pipe 6 and discharged to the external environment. In order to maintain the efficient operation of the dust removal bag 5, the nozzle 24 on the blowing pipe 22, under the control of the pulse valve 23, regularly sprays high-pressure airflow to the inside of the bag to form a short reverse airflow, instantly blowing away and removing the dust attached to the outer surface of the bag. The ash discharge valve 16 under the ash hopper 2 is used to regularly discharge the collected dust and impurities. The second cleaning brush 21 on the rotating rod 18 rotates under the drive of the motor 14, contacts the inner wall of the ash hopper 2, removes the attached dust, ensures smooth ash discharge, and reduces the risk of blockage and dust accumulation.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
