Description

New reverse osmosis membrane shell

technical field

The utility model relates to a pure water machine, in particular to a novel reverse osmosis membrane shell.

Background technique

Household water purifier systems often filter pressurized raw water through reverse osmosis membrane shells. After the raw water is filtered by reverse osmosis membrane shells, clean water and concentrated water are produced. The purified water is stored for later use or used directly, and the concentrated water is discharged directly. In order to protect the reverse osmosis membrane shell, the household pure water machine is equipped with a flushing state device, which will generate a large amount of drainage during the application process, and the waste of water resources is serious. How to improve the existing reverse osmosis membrane shell so that the water inlet effect of the household pure water machine system is better and the flushing and drainage can be recycled has become a problem that people generally pay attention to.

Utility model content

The purpose of the utility model is to overcome the disadvantages of the prior art and provide a novel reverse osmosis membrane shell with good water purification effect, simple structure and water saving.

The purpose of this utility model is achieved through the following technical solutions: a new type of reverse osmosis membrane shell, which includes a membrane shell cover, a fixed baffle, an inner screw cover, a membrane shell and a reverse osmosis membrane, and the described membrane shell cover is closed on the At the top of the membrane housing, a cavity is opened inside the membrane housing, and the reverse osmosis membrane is arranged in the cavity, and the upper end of the reverse osmosis membrane is fixed on the membrane housing cover through a fixed baffle and an inner screw cap, wherein, The fixed baffle is arranged on the inner side of the membrane shell cover, the inner screw cover and the reverse osmosis membrane are connected through thread fit, and the inner screw cover is also fastened with the fixed baffle. The upper end of the membrane casing is provided with a water inlet, and the lower end of the membrane casing is provided with a water outlet.

Further, it includes two water outlets, one of which is connected with the clean water empty pipe, and the purified water flows out from this channel; the other water outlet is connected with the cavity of the membrane shell cover, and the unpurified sewage can flow from this channel.

Further, it also includes a water isolating device, the water isolating device is set on the outer wall of the reverse osmosis membrane, and the water isolating device is located below the water inlet.

Further, the membrane casing cover and the membrane housing are integrally connected by screw threads.

The utility model has the following advantages:

1. By setting two water outlets, they are used to discharge pure water and concentrated water respectively, so that the pure water can be discharged directly for use, and the concentrated water can be recycled after being discharged, saving water and being green and environmentally friendly.

2. By setting the inner cover, the clean water empty pipe is divided into upper and lower parts. When the source water is too much, when the clean water empty pipe enters the reverse osmosis membrane, it will not be directly mixed into the purified water and discharged for use. Therefore, the purification effect is greatly improved, and the problem of pure water being polluted is effectively avoided.

3. By adopting the fixed baffle and the membrane shell cover with screw connection, when replacing or maintaining the reverse osmosis membrane, it can realize quick replacement, installation, etc., which is convenient for operation.

4. Both the water outlet and the water inlet are arranged on the outer wall of the membrane shell, and the replacement of the reverse osmosis membrane can be completed without removing the water pipes connected to the water outlet and the water inlet, which is more convenient.
