Description

TECHNICAL FIELD

[0001] The utility model relates to filter equipment technical field, especially a security filter quick alignment device. BACKGROUND

[0002] The security filter quick alignment device (also called precision filter) is a very important pretreatment component in the reverse osmosis system. Its main function is to remove particulate matter, suspended solids and other impurities that may exist in water before the water enters the reverse osmosis membrane, so as to protect the reverse osmosis membrane from damage. At the same time, it can ensure water quality, stable water production and water quality, maintain stable operation of the reverse osmosis system, and ensure that water production and water quality meet the requirements. With the increase of running time, the membrane pores of the security filter quick alignment device filter core are blocked by pollutants, the rate of water molecules passing through the membrane is reduced, resulting in a significant reduction in system water production, an increase in pressure difference, an increase in energy consumption, and abnormal water quality. Once these phenomena occur, the filter core should be replaced in time to reduce the pollution load entering the reverse osmosis system.

[0003] At present, the security filter quick alignment device filter core used in the domestic reverse osmosis membrane system has a general filtration accuracy of 5 microns, is mostly a melt-blown filter core, has a diameter of 65 mm, a length of 1 m, is opened on one side, has two O-shaped sealing rings, and the other side is sealed in a triangular wing structure. When installing, the O-shaped ring is inserted into the bottom plate hole, the upper side is pressed tightly with the hole plate, and then the pull rod embedded in the bottom plate is locked. When the security filter quick alignment device is small and the number of installed filter cores is small, the top can be aligned and pressed tightly with the whole plate hole plate. When the security filter quick alignment device is large and the number of installed filter cores exceeds 100, if the top is aligned and pressed tightly with the whole plate, the filter cores are difficult to align as a whole because they interfere with each other. When the workers actually perform the alignment operation, it takes 1-2 hours smoothly, and more than 5 hours if not smooth, which seriously affects the work efficiency. UTILITY MODEL CONTENTS
