Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis, in particular to a reverse osmosis treatment device for safe drinking water. Background Art

[0002] Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses pressure difference as the driving force to separate the solvent from the solution. Pressure is applied to the liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will reversely permeate in the opposite direction of natural osmosis.

[0003] The utility model with existing authorization announcement number CN218521115U discloses a reverse osmosis treatment device for safe drinking water, including a pretreatment cylinder and a reverse osmosis filter, the side wall of the pretreatment cylinder is connected with a water outlet pipe, and one end of the water outlet pipe away from the pretreatment cylinder is connected with the water inlet end of the reverse osmosis filter; an inner cylinder is coaxially arranged inside the pretreatment cylinder, a rotating shaft is arranged at the bottom of the inner cylinder, the bottom end of the rotating shaft passes through the bottom wall of the pretreatment cylinder and is fixedly connected to the output end of a motor arranged at the bottom of the pretreatment cylinder, and the top of the inner cylinder is rotatably connected to the top wall of the pretreatment cylinder; a backwashing device is arranged on the side wall of the pretreatment cylinder.

[0004] By adopting the above technical solution, by arranging horizontal bars and vertical bars, the pre-treatment cylinder can be turned over before the backwash device flushes the outer wall of the inner cylinder, so that the pre-treatment cylinder is inverted, and then the outer wall of the inner cylinder is flushed by the backwash device. By piercing filter holes on the top cover, impurities in the cleaning process can be filtered. However, when the above technical solution uses a reverse osmosis filter for filtering, if the filter is blocked or damaged, it is easy to cause a certain impact on the reverse osmosis work of the drinking water, and the staff cannot quickly disassemble the filter for maintenance, which leads to the problem of low practicality.

[0026] The outer surface of the shell 3 is fixedly connected to a water inlet pipe 5, and a control valve 6 is fixedly installed on the outer surface of the water inlet pipe 5. By setting the water inlet pipe 5 and the control valve 6, it is convenient for the staff to inject treated water into the interior, thereby facilitating the use of the staff.

[0027] A handle 7 is fixedly connected to the front of the connecting cover 4, and two fixing blocks 9 are fixedly connected to the two side surfaces of the bottom plate 1. By providing the handle 7, the staff can be assisted in disassembling the reverse osmosis filter element 14, thereby further increasing the disassembly efficiency. By providing the fixing blocks 9, a platform for fixing the device can be provided, thereby avoiding deviation during use.

[0028] The upper surface of each fixing block 9 is threadedly connected with a bolt 10, and the bottom end of each bolt 10 penetrates the fixing block 9 and extends to the bottom of the fixing block 9. By setting the bolt 10, the device can be quickly and firmly fixed so that it can be in a stable working state.

[0029] Two reinforcement blocks 8 are fixedly connected to the front and back of each support frame 2, and the bottom surface of each reinforcement block 8 is fixedly connected to the upper surface of the base plate 1.

At the same time, under the action of the thrust of the push plate 19, the spring 15 will shrink inward, and finally the staff pulls the connecting cover 4 outward through the handle 7, so that the connecting cover 4 can be separated from the shell 3 until the reverse osmosis filter element 14 is disassembled, so that the reverse osmosis filter element 14 can be cleaned and repaired, avoiding the impact on the quality of water treatment due to blockage and damage of the reverse osmosis filter element 14, and improving the practical effect of the device.
