Description

Technical Field

[0001] The utility model belongs to the technical field of anti-clogging screening devices, in particular to an anti-clogging screening structure. Background Art

[0002] The existing ore anti-clogging screening mechanism includes a screening machine, an exhaust box is provided on the top of the screening machine, an exhaust fan is provided on the top of the exhaust box, and a filter is provided inside the exhaust box. After the screening machine screens the ore raw materials, a large amount of smoke and dust will be emitted from the inside of the screening machine. At this time, the exhaust fan is started to extract the smoke and dust inside the screening machine into the inside of the exhaust box. In actual use, after a period of use, a lot of dust will accumulate on the filter net inside the exhaust box, which makes it impossible to filter the smoke and dust inside the screening machine. At this time, the staff needs to disassemble the filter net and then clean the dust on the filter net. Such reciprocating disassembly and cleaning of the filter net is time-consuming and labor-intensive, which does not meet people's usage needs.

[0003] For example, the utility model with announcement number CN219253267U discloses a hardware raw material screening machine provided with a material separation and anti-blocking structure. In the technical solution of this patent, when the exhaust fan exhausts the inside of the screening machine, the smoke and dust inside the screening machine will gather on the filter net inside the collection box. After a period of use, a thick layer of dust will gather on the filter net. At this time, the staff needs to disassemble and clean the filter net, and then install the filter net inside the collection box. This processing method is time-consuming and labor-intensive, and the machine needs to be shut down, affecting production efficiency. Therefore, an anti-blocking screening structure is proposed.
