Description

A fully automatic medical purified water system Technical Field

[0001] The present invention relates to the technical field of purified water, in particular to a medical fully automatic purified water system. Background Art

[0002] Pharmaceutical factories require high-purity water in their production processes, and purified water is essential for drug manufacturing. There are three process flows for purified water equipment used in pharmaceutical factories, each with its own unique advantages and scope of application. In the first process flow, the raw water is treated through multiple processes such as a raw water pressure pump, a multi-media filter, an activated carbon filter, a water softener, a precision filter, and a first-stage reverse osmosis device. The purified water is then processed through an intermediate water tank, an intermediate water pump, an ion exchanger, a purified water tank, a pure water pump, an ultraviolet sterilizer, and a microporous filter. The advantages of this process flow are high treatment efficiency, good treatment effect, and excellent removal of various pollutants. It is suitable for pharmaceutical factories that require large outputs. The second process flow first undergoes process treatments such as a raw water pressure pump, a multi-media filter, an activated carbon filter, a water softener, a precision filter, a first-stage reverse osmosis, and a pH adjustment. The purified water is then processed through an intermediate water tank and a second-stage reverse osmosis device. The advantages of this process flow are good average water quality, energy saving, and more stable treatment effect. It is suitable for pharmaceutical factories that require higher-quality pure water.

[0003] During the production of purified water, as the equipment is used for a longer time, the performance of filter elements and other filtering components will decline and need to be replaced regularly. During the replacement process, the equipment needs to be shut down, which affects the production efficiency of purified water.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the medical fully automatic purified water system:

[0016] 1. The replacement mechanism solves the problem of needing to shut down for filter element replacement. As the equipment is used for an extended period of time, the performance of filter elements and other filter components will decline and require regular replacement. When the filter element needs to be replaced, the cover provided at the upper end of the multi-media filter is removed, and then the filter element to be replaced in the multi-media filter main housing is taken out from the upper end opening of the multi-media filter main housing. When the old filter element is taken out, the push plate pushes the new filter element from the multi-media filter side housing into the multi-media filter main housing under the action of the spring, so that the filter element can be replaced without shutting down the machine. When the filter element in the multi-media filter side housing needs to be replenished, the pull rod is first pulled out, and then the pull rod is rotated 180 degrees so that the protrusion provided on the pull rod engages with the opening of the multi-media filter side housing, and then the new filter element is inserted from the core replacement port provided at the upper end of the multi-media filter side housing to complete the replenishment, ensuring that there is a new filter element at any time to replace the old filter element.

[0017] 2. The circulation system solves the problem of providing a backup line for purified water production when the performance of purified water system components declines. When the performance of purified water system components declines and the quality of the purified water produced is unqualified, the conductivity detector detects the unqualified purified water, thereby opening the electric control valve and circulation pump at one end of the circulation pipe, and closing the water outlet. The unqualified purified water flows into the backup filter and ultraviolet sterilizer for further treatment, and then flows into the water source tank. The water outlet will not be opened until the conductivity detector detects that it is qualified, so as to avoid the outflow of unqualified purified water and cause unqualified product quality, and remind the staff that the performance of system components has declined and needs to be replaced.
