Abstract
Description
Technical Field
[0001] The utility model belongs to the field of reverse osmosis in pure water production and relates to a reverse osmosis device for industrial pure water. Background Art
[0002] Pure water is a liquid with a certain structure. Although it has no rigidity, its arrangement is much more regular than that of gaseous water molecules. In liquid water, water molecules do not exist in the form of single molecules, but several molecules form water molecule clusters (H2O) by hydrogen bonding. Therefore, the orientation and movement of water molecules will be significantly affected by other surrounding water molecules. There is no definite structural model for the structure of water. Currently, there are three main types that are accepted by most people: mixed type, interstitial type and continuous structure (or uniform structure) model. Most of the existing reverse osmosis devices used for pure water production use reverse osmosis membranes for pure water filtration operations. Most of the reverse osmosis membranes use the structure of a central tube wound filter membrane. After long-term use, the rolled reverse osmosis membrane is removed and replaced with a new reverse osmosis membrane. The replacement process requires downtime, which affects the production efficiency of pure water.
[0003] Therefore, the utility model provides a reverse osmosis device for industrial pure water to solve the above problems. Utility Model Content

[0005] As a preferred solution of the utility model, a water pump is installed on the horizontal part of the L-shaped drain pipe; by adopting the water pump, the water entering the reverse osmosis mechanism forms a certain pressure, which facilitates the operation of the reverse osmosis membrane.
[0006] As a preferred solution of the utility model, threads are respectively provided at the left and right ends of the outer tube, and the sealing cover is screwed onto the threads; a screwing design is adopted between the outer tube and the sealing cover, which facilitates the quick opening of the outer tube when replacing the reverse osmosis membrane, thereby improving the convenience of replacement.
[0007] As a preferred solution of the utility model, an electromagnetic valve is installed on one end of the flow guide tube located outside the sealing cover.
[0008] As a preferred solution of the utility model, a drain pipe is opened on the lower side wall of the left end of the outer tube, and a valve is installed on the drain pipe; by opening the drain pipe, impurities such as industrial pollutants, heavy metals, bacteria, viruses, etc. filtered through the reverse osmosis membrane can be discharged through the drain pipe.
[0009] As a preferred solution of the present invention, the second filter plate adopts granular activated carbon as filter material. By adopting granular activated carbon as filter material, residual chlorine, organic matter, suspended matter and other impurities in water can be further removed. The third filter plate adopts compressed activated carbon as filter material. By adopting compressed activated carbon as filter material, odor in water can be filtered out.
[0010] The beneficial effects of the utility model are as follows: by sequentially arranging the first filter plate, the second filter plate and the third filter plate from left to right in the box body, the residual chlorine, organic matter, suspended matter and other impurities as well as odor in the water are filtered out, and then the waste water containing industrial pollutants, heavy metals, bacteria, viruses and other impurities is discharged through the filtering effect of the reverse osmosis membrane, so as to obtain pure water. When the reverse osmosis membrane needs to be replaced, the electromagnetic valves on the front and rear sides on the right side can be automatically switched to realize the rapid switching of the reverse osmosis mechanisms on the front and rear sides, so that the reverse osmosis membrane can be quickly replaced without stopping the machine, thereby improving the production efficiency of pure water.
