Technical Field
[0001] The utility model belongs to the technical field of filter elements, and in particular relates to a filter element fixing device for a filter. Background Art
[0002] The filter element is a simple device for purifying the resources of the original fluid and separating the resources. Now the filter element is mainly used in the filtration industry such as oil filtration, air filtration and water filtration. The filter element separates the solid particles in the liquid or gas, or makes the different material components fully contact, speeds up the reaction time, and can protect the normal operation of the equipment or the cleanliness of the air. When the fluid enters the filter element with a filter screen of a certain specification, its impurities are blocked, and the clean fluid flows out through the filter element. A fixing device is required when installing the filter element.
[0003] During use, the existing fixing device fixes the filter element by multiple sets of bolts, thereby reducing the impact force caused by fluid flow, which causes the filter element to shake frequently. However, during long-term use, the filter element needs to be cleaned and replaced regularly to prevent it from being blocked. During the replacement process, the bolts need to be disassembled and installed one by one, and the steps are cumbersome. Therefore, we provide a filter element fixing device for the filter.
