Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a filter element that is easy to replace. Background Technology

[0002] Nuclear wastewater is wastewater containing radioactive materials generated from nuclear power plants and nuclear-related medical institutions or laboratories. It mainly originates from wastewater generated during the normal operation of nuclear power plants, such as nuclear reactor cooling water. This wastewater can be safely discharged through pipelines after treatment.

[0003] Currently, in existing technologies, most filter cartridges are pushed into the filter from the tail end. However, most filters have a certain taper, so when pushing in the cartridge, the tail end is slightly higher than the filter in a suspended configuration, making the cartridge easily squeezed and damaging the filter media. Therefore, we propose a filter cartridge that is easy to replace. Utility Model Content

When replacement is needed, the wastewater inside the main body of the device is drained, the bolts are removed through the threaded connection holes, and the top shell is removed from the top of the bottom shell. Pulling the fixing pin causes it to move backward, moving out of the filter element holder and compressing the spring, thus unlocking the fixing pin's hold on the filter element holder. A crane is then used to lift the filter element holder, diaphragm, and filter assembly for replacement. The new filter element is placed back into the mounting frame, where its own weight compresses the rigid airbag, causing the gas to push the push rod forward. The spring then moves the fixing pin. If the new filter element is not properly installed, the push rod compresses the spring; if it is properly installed, the spring pushes the fixing pin into the filter element holder, securing the new filter element. The top shell is then reinstalled, completing the replacement. The positioning of the fixing pin and the compression of the filter element holder by the rigid airbag ensure that the filter element will not shake even under high water pressure.
