Description

Technical Field

[0001] The utility model relates to a filtering device, in particular to a reverse osmosis filtering device. Background Art

[0002] Recycled water reuse technology refers to the centralized treatment of residential wastewater (bathing, washing, laundry, kitchen, toilet) to meet certain standards and reuse it for greening irrigation, vehicle washing, road washing, household toilet washing, etc. in the community, so as to achieve the purpose of saving water. Reverse osmosis filtration equipment is usually installed in the recycle water reuse system. The core component of the reverse osmosis filtration equipment is the filter installed with reverse osmosis membrane. In order to meet the use requirements of industrial production, the reverse osmosis filtration equipment of the industrial recycle water reuse system is usually installed with several reverse osmosis filters connected in parallel.

[0003] In the prior art, according to a Chinese patent, a patent with application number CN202320117723.4 discloses a reverse osmosis filtration device for reclaimed water reuse, and its working principle is: a number of reverse osmosis filters are placed on a U-shaped plate for installation and fixation, and then the branch water inlet pipe of the main water inlet pipe is connected to the water inlet of the reverse osmosis filter, and the water outlet of the reverse osmosis filter is connected to the branch water outlet pipe of the main water outlet pipe. An RO membrane is installed in the reverse osmosis filter, and sewage enters the reverse osmosis filter through the main water inlet pipe and the branch water inlet pipe. After being filtered through the RO membrane of the reverse osmosis filter, clean water is discharged through the branch water outlet pipe and the main water outlet pipe.

[0004] The existing reverse osmosis filtration equipment has certain defects when in use. The reverse osmosis filtration equipment relies on a reverse osmosis filter with a reverse osmosis membrane to achieve filtration. In order to ensure the filtration efficiency, the reverse osmosis filtration equipment uses multiple reverse osmosis filters in parallel. The reverse osmosis membrane is damaged when the reverse osmosis filter is in use. Since the reverse osmosis filter on the current reverse osmosis filtration equipment is fixed on the equipment mounting frame and is not convenient for disassembly, when the reverse osmosis filter needs to be disassembled for replacement and cleaning, it takes a long time to disassemble, which is troublesome and laborious. As a result, the reverse osmosis filter on the reverse osmosis filtration equipment cannot be easily replaced, which in turn causes the filtration efficiency of the reverse osmosis filtration equipment to decrease. Therefore, improvements are now made to the reverse osmosis filtration equipment. Utility Model Content

When the positioning part 22 is against the upper side of the rib plate 13, the insert tube 23 moves to the lower side of the limit block 122. At this time, the limit block 1 22 pops out under the action of the spring 123 and presses against the upper side of the insert 23, so that the reverse osmosis filter 21 is fixed on the fixing frame 12.
