AI Technical Summary

Technical Problem

The existing high-pressure blower inlet filter screen has low disassembly and maintenance efficiency. It is prone to loosening or failure due to high-frequency vibration. Moreover, the air inlet is not protected during disassembly, which allows foreign objects to enter and affect the stability and safety of the blower operation.

Method used

The system employs a flexible snap-fit ​​and linkage unlocking structure to enable tool-free quick assembly and disassembly. Combined with a flip-up mounting cover for temporary filtration and a dual-stage filtration design, along with a rotatable mounting cover and elastic band positioning structure, it ensures installation accuracy and sealing.

Benefits of technology

It improves maintenance efficiency and structural reliability, avoids loosening or jamming of connections, ensures that the filtration effect is not compromised, reduces the risk of foreign object intrusion, and extends the service life of the fan.

Abstract

The invention belongs to the technical field of high-pressure fan corollary equipment, and particularly relates to a high-pressure fan inlet filter screen quick-release structure capable of preventing foreign matter from being sucked in, which comprises a high-pressure fan body, an air inlet is fixedly connected to the side wall of the high-pressure fan body; a filter screen body is arranged on one side of the air inlet; one end of the filter screen body is fixedly connected with a supporting block; by means of the elastic clamping and linkage unlocking structure, the core defects that a traditional fixing mode of an existing high-pressure fan inlet filter screen is tedious in disassembly and assembly and depends on tools are overcome, tool-free rapid disassembly and assembly are achieved, and the maintenance efficiency is greatly improved; compared with the prior art, the structure is optimized aiming at the high-frequency vibration environment of the high-pressure fan, so that outstanding substantive features are formed, and the phenomenon of clamping looseness or clamping is effectively avoided; maintenance convenience and structural reliability are improved, installation precision can be automatically guaranteed, the problem of abnormal air inlet resistance or filtering failure caused by installation deviation is avoided, and stable operation of the high-pressure fan is guaranteed.
