Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membranes, in particular to a reverse osmosis membrane cleaning device. Background Art

[0002] Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane, and is the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate these substances and water under the action of higher osmotic pressure than the solution, based on the fact that other substances cannot pass through the semipermeable membrane. However, after the reverse osmosis membrane has been used for a long time, smaller particles will be left inside the central gap, causing the filtering effect of the reverse osmosis membrane drum to decrease. The existing cleaning methods are mostly to soak the reverse osmosis membrane drum in drugs first, and then clean the drug residues on the surface and inside of the reverse osmosis membrane drum with clean water, so a reverse osmosis membrane cleaning device is needed.

[0003] When the existing reverse osmosis membrane cleaning device flushes the surface of the reverse osmosis membrane drum, most of them only set multiple groups of nozzles on the top of the immersion tank, so that the flushing of the reverse osmosis membrane drum is not comprehensive enough, and there are still residual medicines and particles on the surface and inside, which affects the subsequent use. Therefore, we propose a reverse osmosis membrane cleaning device to solve the above problems. Utility Model Content

[0022] The rear side of the first transmission wheel 3 is connected to a motor through a pulley, so that the rotation of the motor drives multiple first transmission wheels 3 of the cleaning box 1 to rotate, so that the surface of the reverse osmosis membrane drum can be fully rinsed during the cleaning process, and a rubber plate is arranged at the front end of the first transmission wheel 3 to increase friction, so that the first transmission wheel 3 can be close to the reverse osmosis membrane drum and follow the rotation after being squeezed.
