Secondary water supply device

Abstract

The invention discloses a secondary water supply device, and belongs to the technical field of water supply devices. The secondary water supply device comprises a water storage type pressure stabilizing tank, wherein a backflow main pipe is clamped and connected onto the side end surface of the water storage type pressure stabilizing tank; and a pair of anode water wheels and cathode water wheels is arranged inside the backflow main pipe. Through the conversion and utilization of wind energy and municipal water supply pipe network water power, the comprehensive purification of drinking water can be favorably realized; the long-time and uninterrupted drinking water circulation purification effect can also be achieved; through micro electrolysis sterilization, the microbe propagation process is blocked; through the circulation reciprocating action of a descaling brush on the cathode water wheels, the contact area of the cathode water wheels and the drinking water is effectively ensured; the micro electrolysis sterilization and mite removal effect of the drinking water is improved; the multi-stage automatic pressurization effect of the drinking water can also be realized by using an anode shaft, a cathode shaft, a movable vortex disc and a static vortex disc; and the occurrence of problems of insufficient water pressure and the like during the subsequent solid-liquid separation of the drinking water can be avoided.

Description

technical field [0001] The invention belongs to the technical field of water supply equipment, in particular to secondary water supply equipment. Background technique [0002] Secondary water supply equipment refers to a kind of equipment that solves the water problem of residents through on-the-spot survey, test and research and development by the operators of the water supply industry. According to the water demand of the majority of users, the secondary water supply equipment is mainly composed of air pressure tanks, water pumps and control systems. For squares, campus villas, school hospitals, etc., the secondary water supply equipment adopts automatic operation, energy saving and automatic grid connection of tap water, and water supply can still be implemented after power failure. [0003] Due to the reason of water delivery in the existing secondary water supply equipment, the secondary water supply will exist for a long time, and it is easy to cause a large amount of...

AI Technical Summary

Problems solved by technology

[0003] Due to the reason of water delivery in the existing secondary water supply equipment, the secondary water supply will exist for a long time, and it is easy to cause a large amount of impurities to precipitate in the drinking water in the surge tank, thereby reducing the purity of the drinking water, and the impurities in the water during the storage process It is easy to settle in the interior of the secondary water supply equipment, and it is easy to breed plankton and microorganisms. Some algae can also produce toxins, and the number of coliform bacteria seriously exceeds the standard, which poses a great threat to people's life and health.

[0004] In order to reduce the bacterial content inside the secondary water supply equipment, drinking water purification equipment is usually added to the secondary water supply equipment, but because the drinking water inside the secondary water supply equipment is in direct contact with the air in the tank, part of the air will dissolve in the drinking water In the water, the water pressure in the secondary water supply equipment is already in a state of gradually decreasing, and by adding drinking water purification equipment, the water pressure will be weakened again, which will seriously affect the stability of the secondary water supply equipment and affect the use effect. Therefore, there is an urgent need for a secondary water supply equipment on the market at this stage to solve the above problems
