Filter element dismounting device

Abstract

The invention discloses a filter element dismounting device. The filter element dismounting device comprises a water purification filter drum, the water purification filter drum comprises an outer drum, a plurality of locking assemblies and a filter element, and each locking assembly comprises a locking screw and a pressing plate. The filter element dismounting device is characterized by further comprising a dismounting tool; the dismounting tool comprises a fine-thread nut, a positioning plate, a pull rod, a connecting plate and a plurality of screws; the positioning plate is provided with aplurality of round holes, the outer circle surface of the left part of the pull rod is provided with a fine external thread, the right part of the pull rod is provided with a square tenon, and the right end face of the connecting plate is provided with a line-shaped groove; and the fine-thread nut is installed on the left part of the pull rod through threaded connection, the square tenon on the right part of the pull rod is installed in the line-shaped groove in the right end face of the connecting plate, and the positioning plate sleeves the pull rod and is installed between the fine-thread nut and the connecting plate. The filter element dismounting device is novel in structure and reliable in work, dismounting is fast, and labor is saved during operation.

Description

technical field [0001] The invention relates to a tool, in particular to a filter element removal device used in a pure water machine. Background technique [0002] Before the surface coating treatment of automobile aluminum alloy wheels, in order to ensure the quality of the coating, it is necessary to use pure water to clean the surface of the automobile aluminum alloy wheels. However, most of the pure water currently used is pure water equipped with reverse osmosis membrane filters. After the filter element is used for a long time, the quality of the prepared pure water cannot meet the process requirements, and the filter element must be replaced. The existing method of replacing the filter element is to manually loosen the locking screws of the water purification filter cartridge one by one and remove the pressure plate. Then manually use a wooden stick to continuously beat the filter element installed in the outer cylinder from the back of the water purification filter ...

[0002] Before the surface coating treatment of automobile aluminum alloy wheels, in order to ensure the quality of the coating, it is necessary to use pure water to clean the surface of the automobile aluminum alloy wheels. However, most of the pure water currently used is pure water equipped with reverse osmosis membrane filters. After the filter element is used for a long time, the quality of the prepared pure water cannot meet the process requirements, and the filter element must be replaced. The existing method of replacing the filter element is to manually loosen the locking screws of the water purification filter cartridge one by one and remove the pressure plate. Then manually use a wooden stick to continuously beat the filter element installed in the outer cylinder from the back of the water purification filter cartridge, and take the filter element out of the outer cylinder. Because this method is difficult to grasp the strength of each force point during operation, this method of disassembly is extremely difficult. Time-consuming and inefficient
