Description

Technical Field

[0001] This invention relates to the field of filtration equipment maintenance technology in industries such as aviation fuel, petrochemicals, and environmental protection, and particularly to a filter element cleaning device. Background Technology

[0002] In existing technologies, filter element cleaning and water spray testing rely entirely on manual labor: two people work together, one holding the filter element while the other rinses or sprays it with water using a spray gun, while simultaneously conducting visual inspection. This method lacks a dedicated fixing device, making operation extremely inconvenient. The closest existing technology to this solution uses a simple bracket to place the filter element horizontally, but this still requires manual rotation and cannot reliably fix or rotate it. These methods are labor-intensive, require two people, the filter element is prone to slipping and damage, inspection is incomplete, efficiency is low, and on-site water drainage is inconvenient. Summary of the Invention

An oil collection tank, located directly below the countertop filter, is used to collect cleaning wastewater. A rotating bracket, fixed on a movable platform, is located behind the water tank; the rotating bracket is equipped with a bearing seat and a rotating shaft; A filter element fixing clamp is fixedly mounted on the rotating shaft for installing the filter element; The operating handwheel, located at one end of the rotating shaft, is used to rotate the filter element by an angle. A positioning locking pin is installed between the operating handwheel and the movable bracket to lock the rotation angle of the filter element.

[0005] Preferably, the filter element fixing clamp includes an adjustable hose clamp.

[0006] Preferably, the clamping surface of the adjustable hose clamp is lined with rubber.

[0007] Preferably, the bottom of the mobile platform is equipped with casters and directional wheels.

[0009] Preferably, the movable platform is made of stainless steel.

[0010] Preferably, the adjustable hose clamp has an adjustment range of Φ80~Φ200mm.

[0011] The beneficial effects of this invention are: This invention discloses a filter element cleaning device that, through the cooperation of a rotating bracket, an operating handwheel, and a positioning locking pin, enables multi-angle rotation and reliable locking of the filter element, facilitating all-around cleaning by operators and significantly improving cleaning uniformity and cleanliness. The filter element fixing clamp adopts an adjustable structure, adaptable to filter elements of different diameters, offering strong versatility and a secure clamping mechanism, effectively preventing filter element detachment or displacement during cleaning. The oil collection tank centrally collects cleaning wastewater and oil, avoiding on-site pollution and meeting environmental protection requirements. The water tank pre-filter purifies the cleaning water, reducing secondary contamination of the filter element by impurities in the water. The entire device employs a mobile platform structure equipped with casters and handrails, facilitating movement between different workstations, offering high flexibility, and reducing the labor intensity of operators.
