Description

Synchronous opening and closing assembly of upper and lower connecting covers and energy-saving water-saving medical reverse osmosis pure water device

Technical Field

The invention relates to the technical field of medical pure water preparation devices, in particular to an upper and lower connecting cover synchronous opening and closing assembly and an energy-saving water-saving medical reverse osmosis pure water device.

Background

Reverse osmosis membranes in medical reverse osmosis devices are consumables. In order to ensure the water production efficiency of the reverse osmosis membrane and reduce the discharge of wastewater, the reverse osmosis membrane needs to be cleaned after being used for a period of time, so that the blocking of the membrane is prevented, and the water efficiency is reduced.

When the reverse osmosis membrane is taken out and cleaned, the filter cylinder is required to be opened by means of a special tool, and the water inlet and outlet pipelines of the reverse osmosis membrane are manually removed, so that the special technical requirements on operators are high, the situation that the pipelines are not spliced in place after the reverse osmosis membrane is installed easily occurs, and water leakage of the pipelines is caused when pure water is prepared.

In addition, on the more important hand, due to lack of professional maintenance, most reverse osmosis membranes run in an out-of-date mode, the gradual blockage of the membrane can reduce the water yield of pure water, and the waste water is discharged excessively, so that a water source is wasted greatly. In order to solve the problem, the conventional solution is to backwash the currently used reverse osmosis membrane in a non-aqueous state at night and discharge the impurities attached to the membrane in a reverse direction according to the filtering direction. This method is simple and effective, but in a period of time in which the reverse osmosis membrane is flushed, pure water cannot be used because of lack of water, and in a hospital or the like where pure water is used without interruption, this simple method cannot meet the demand for water.
