Description

technical field [0001] The invention relates to a diamond micropowder ultrasonic screening device, which belongs to the field of artificial diamond processing. Background technique [0002] In the diamond micropowder ultrasonic screening devices currently used, a screening sieve, a feeding mechanism and a discharging mechanism are often used to form a complete screening system, such as the screening equipment with application number: 201120177566.3 and application number: 201420718174.7 Although this type of structure used can meet the needs of use, it is found in the work that the working efficiency of the feeding mechanism and the discharging mechanism is much greater than the screening efficiency of the screening screen, so the screening screen seriously restricts the feeding mechanism and The working efficiency of the discharge mechanism leads to low working efficiency of the entire diamond powder screening device, especially when screening and classifying diamond powder...

Problems solved by technology

[0002] In the diamond micropowder ultrasonic screening devices currently used, a screening sieve, a feeding mechanism and a discharging mechanism are often used to form a complete screening system, such as the screening equipment with application number: 201120177566.3 and application number: 201420718174.7 Although this type of structure used can meet the needs of use, it is found in the work that the working efficiency of the feeding mechanism and the discharging mechanism is much greater than the screening efficiency of the screening screen, so the screening screen seriously restricts the feeding mechanism and The working efficiency of the discharge mechanism leads to low working efficiency of the entire diamond powder screening device, especially when screening and classifying diamond powder raw materials. In view of this situation, the current main solution is often to increase screening. The number of devices can be used to achieve the output of screening operations per unit time, but it has caused the disadvantages of large equipment investment costs and relatively high equipment operating costs

[0003] In addition, all kinds of diamond micropowder ultrasonic screening devices currently in use lack the ability to effectively control the feeding position of diamond micropowder. On the one hand, it is very easy to cause the diamond micropowder to accumulate too thickly in the screening mechanism, which seriously affects the screening. The efficiency of the operation, and it is very easy to cause the sieve hole of the screening equipment to be blocked. On the other hand, it is also very easy to cause the uneven thickness distribution of the diamond powder in the screening equipment, which in turn causes the uneven load distribution of the screening equipment during operation, which affects the screening efficiency. At the same time as the quality and quality, it also leads to serious local wear and tear of the screening equipment due to uneven load distribution, tilt, polarization, etc., and it is easy to further aggravate the accumulation of diamond fine powder, which seriously affects the work efficiency and quality of diamond fine powder screening. It also leads to relatively poor stability and continuity of the screening equipment
