Pure water storage device

Abstract

The invention discloses a pure water storage device which comprises a water bucket. A bucket cover is arranged on the top of the water bucket. A through hole is formed in the bottom of the water bucket. The pure water storage device further comprises a water storage bag. The top of the water storage bag is fixed to the bucket cover, and the bottom of the water storage bag is fixed into the through hole in the bottom of the water bucket. A water drainage/exhaust pipe is communicated with the top of the water storage bag and provided with a check valve. A water inlet/outlet pipe is communicated with the bottom of the water storage bag. The bottom of the water storage bag is communicated with a liquid level sensor arranged outside the water bucket. The water storage bag is a sealed plastic bag made of medical or food grade materials such as PE-polyethylene. According to the pure water storage device, the one-time replacement way replaces periodic cleaning and disinfection, meanwhile, exhaust and overflowing prevention purposes are achieved, and the effect basically equal to the effect of an open container is achieved. By using the medical or food grade plastic bag (such as PE) which is widely applied at present, the most visual and feasible purpose that the materials are reliable and controllable is achieved, and the surface smooth finish can reach the extremely high level.

Description

technical field [0001] The invention belongs to the technical field of pure water equipment, in particular to a pure water storage device in the pure water equipment. Background technique [0002] Usually, tap water or natural water sources become pure water after reverse osmosis filtration, ion exchange, distillation and other methods. Pure water often cannot be used as it is made, but requires a certain amount of storage before it can be used. Since the various pollutants in pure water (including particulate impurities, inorganic substances, organic substances, bacteria, etc.) are already extremely low, the requirements for anti-secondary pollution in the storage process of pure water are very strict. The containers are as follows: [0003] One is a non-pressure storage tank (the material can be PE plastic, stainless steel, etc.). In order to achieve the purpose of anti-pollution, immersion UV, regular cleaning and disinfection of the inner cavity, addition of breathing ...

AI Technical Summary

Problems solved by technology

[0008] 3) The material cleanliness of the container itself and the smoothness of the inner wall are not easy to control;

[0009] 4) Although the pressure vessel is completely sealed, it will bring more complicated problems of pressure, flow and air bubbles to the upstream and downstream equipment in the storage and distribution links
