Description

A vibrating powder sieve with multiple groups of side powder

technical field

The invention relates to a powder sieve, in particular to a vibrating powder sieve with multiple groups of side down powder.

Background technique

In the electrostatic powder spraying industry, the powder screening equipment is generally a plane vibrating screen. For details, please refer to the following introduction:

The existing planar vibrating screen adopts a disc-shaped standard powder sieve structure, and the screen frame and screen mesh transmit vibration through the vibrating motor of the vibrating screen shell. Due to the low screening capacity of the planar vibrating screen, it is generally used for the screen diameter of the powder coating production line. Generally, it is Φ450~Φ800 mm. Due to the large screen area, when the spraying production line changes the powder color, the cleaning time of the vibrating screen is longer. Although the current ultrasonic vibrating screen can improve the screening capacity, the reduction in the area of the screen is not large, and it cannot solve the problem of long screening time of the vibrating screen. Another patent number is 201410413577.5 for a multi-faceted penetrating vibrating sieve, which also belongs to our company's patent. Part of the problem, but there is no patent involving multiple sets of sieve basket side powder, and its sieving capacity can be further improved.
