Description

Technical Field

[0001] The present application relates to the technical field of dust removal equipment, and in particular to a dust removal device for use in an alarm probe production workshop. Background Art

[0002] The dust removal system in the alarm probe production workshop is primarily used to remove dust, particulate matter, and other pollutants from the air to maintain a highly clean production environment. Its core purpose is to protect precision electronic and optical components from contamination during the manufacturing and assembly process, preventing dust from affecting sensor sensitivity, circuit connection reliability, or lens transmittance. This ensures product quality, reduces defective rates, and ultimately ensures stable and reliable performance of the alarm probes.

[0003] The core structure of existing air purification devices includes a casing, a multi-stage filter group, and a centrifugal fan. The casing has an air inlet on one side, inside which a multi-stage filter group is bolted. The centrifugal fan is mounted on the outside of the casing and connected to the interior. During operation, the negative pressure generated by the fan drives air in through the air inlet, which is then purified by the multi-stage filter group and discharged from the fan. Maintenance is a key part of the operation of this device: the casing must be opened regularly, and staff must use special tools to remove and replace the filter group, and simultaneously remove dust attached to the inner wall of the casing. This maintenance process is crucial to ensure that the air circulation path is unobstructed and prevent dust accumulation from causing a decrease in filtration efficiency or an increase in wind resistance.

[0004] Regarding the above-mentioned related technologies, during maintenance, due to the small space inside the shell, the workers' arm movements are limited and tools are difficult to use, resulting in time-consuming and labor-intensive maintenance, thereby resulting in low maintenance efficiency of the air purification device. Summary of the Invention
