Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically to a vibrating screen for lead-zinc ore beneficiation that facilitates cleaning of the filter screen. Background Technology

[0002] Since lead-zinc minerals often contain many fine particles and impurities, they easily clog traditional vibrating screen filters, thus affecting screening efficiency and output. The easy-to-clean filter design simplifies maintenance, allowing operators to clean the screen quickly and avoiding prolonged downtime caused by clogging.

[0003] For example, the utility model patent CN216728192U describes a vibrating screen for easy cleaning of a filter screen used in lead-zinc ore beneficiation experiments. It includes a base and a positioning plate. A screen box is connected to the surface of the base, and a feed hopper is connected to the surface of the screen box. A filter screen is connected inside the screen box. The positioning plate is connected to one side surface of the filter screen, and a mounting cavity is connected to its surface. The filter screen is connected to the screen box via the positioning plate. A fixing rod is connected to the inner wall of the screen box, and a rotating pin is connected to its surface. This vibrating screen for easy cleaning of a filter screen in lead-zinc ore beneficiation experiments achieves this by rotating a positioning pin on the surface of a rotating plate, causing the positioning pin to loosen. The filter screen then connects to the screen box via the positioning plate, while the positioning plate is fixed to the screen box via the positioning pin on the rotating plate. The filter screen can then be removed from the screen box, thus facilitating disassembly and cleaning.

[0004] However, during normal operation, the auxiliary feeding components of the device are fixed in position, making it inconvenient to adjust their position according to usage requirements, which is detrimental to subsequent screening operations. Utility Model Content
