Stable water feeding and supplementing device for recycling shower wastewater

Abstract

The invention discloses a stable water feeding and supplementing device for recycling shower wastewater. The stable water feeding and supplementing device comprises a water feeding device, an air and liquid separating device and a drain device, and is characterized in that the water feeding device comprises a water feeding pipe and a non-self-priming pump; the air and liquid separating device comprises an air and liquid storage cavity, a water feeding opening and a water drawing opening; the drain device comprises a water supplementing mechanism and an exhaust mechanism; the water feeding pipe is connected with the water feeding opening, the non-self-priming pump is connected with the water drawing opening, and the water supplementing mechanism is connected with the air and liquid storage cavity; the exhaust mechanism is connected with the air and liquid storage cavity. The stable water feeding and supplementing device has the advantages that the stable water feeding and supplementing device is high in water feeding suction head and flow and low in cost and noise, and is small, and water can be stably fed by the stable water feeding and supplementing device; air entrained in the water feeding pipe can be effectively separated and exhausted and can be effectively prevented from flowing into the non-self-priming pump, and accordingly the water can be stably fed by the stable water feeding and supplementing device.

Description

technical field [0001] The invention provides a shower wastewater recovery and reuse water replenishment device, in particular to a shower wastewater recycling and reuse stable water replenishment device. Background technique [0002] In the occasion of recycling shower waste water, it is sometimes necessary to suck the shower waste water to a certain height in order to adapt to the requirements of different shower waste water recovery and reuse systems. Directly use the self-priming impeller pump of the prior art, which has large volume, large power consumption, loud noise, and high cost; there is also a diaphragm pump with a high suction lift, because the pressure membrane of this pump is a layer of membrane material, The service life is short, and the liquid with impurities cannot be conveyed, and the noise is loud and the power consumption is large; the above existing water supply technology cannot solve the high suction, large flow, small noise, long life, small volume,...

AI Technical Summary

Problems solved by technology

Directly use the self-priming impeller pump of the prior art, which has large volume, large power consumption, loud noise, and high cost; there is also a diaphragm pump with a high suction lift, because the pressure membrane of this pump is a layer of membrane material, The service life is short, and the liquid with impurities cannot be conveyed, and the noise is loud and the power consumption is large; the above existing water supply technology cannot solve the high suction, large flow, small noise, long life, small volume, low cost problem

My patent number is ZL201520114980.8, a water supply technology in a shower waste heat recovery hot water system. By providing a water replenishment device for a non-self-priming water pump, it solves the problem of high suction, large flow, small noise, long life, The problem of small volume and low cost; but the water supply device is only a single on-off solenoid valve, which cannot effectively separate and discharge the entrained air in the upper water pipe, and cannot effectively prevent air from entering the interior of the non-self-priming pump

In fact, as long as a little air enters the water supply pipe during the water work process, the pressure in the non-self-priming pump will drop rapidly, resulting in unstable water supply or even pumping failure. At this time, the solenoid valve must be opened to replenish water again, resulting in intermittent water supply

Therefore, in order to eliminate the instability of the water supply, it is necessary to ensure that the water supply pipe cannot enter the air, which is difficult to achieve in practical applications, because the water falls into the collector through the human body during the bathing process is dynamic, and it is difficult to ensure that the air does not enter
