Anti-clogging jet pump and anti-clogging method for reclaiming and reusing reclaimed water resources

Abstract

The invention relates to an anti-blocking jet pump for a recycling reclaimed water resource and an anti-blocking method thereof. The anti-blocking jet pump comprises a vertically arranged jet pump body. A funnel-shaped upper water outlet pipeline and a vertical tube-shaped lower water inlet pipeline are arranged in the jet pump body; the upper water outlet pipeline communicates to the lower waterinlet pipeline; a piston type nozzle assembly is arranged at the lower end of the lower water inlet pipeline; the lower portion of the assembly communicates to a tap water pipeline; a through hole isformed in a shell on one side of the lower portion of the jet pump body; one end of the through hole communicates to the lower water inlet pipeline in the jet pump body and the upper space of the piston type nozzle assembly; and the other end of the through hole communicates to a reclaimed water supply device through a hose. The anti-blocking jet pump provided by the invention can prevent blockingof the nozzles effectively, and the anti-blocking jet pump provided by the invention has the function of a check valve, can prevent the reclaimed water from flowing into the tap water pipeline and avoid water pollution. In addition, the plurality of nozzles designed by the anti-blocking jet pump can form multiple strands of jet flows, so that the contact area of a tap water flow and a reclaimed water flow is increased, and the mixed suction efficiency on the reclaimed water is increased.

Description

technical field [0001] The invention relates to a water-saving and environment-friendly device, in particular to an anti-blocking jet pump applied to a reclaimed water recycling system for urban household water and a related anti-blocking method. Background technique [0002] At present, with the continuous development of my country's economy, the process of industrialization and urbanization is accelerating, the water consumption and sewage discharge of urban households are increasing, and the shortage of water resources is becoming more and more serious. In addition, various factors such as natural disasters and water pollution Therefore, saving water has become the duty of every citizen. [0003] The water recovery and reuse system of urban households is one of the effective ways to save water and solve the shortage of water resources. However, due to the order of urban construction and the existence of various old districts that need to install or renovate water recyclin...

AI Technical Summary

Problems solved by technology

[0005] 1. The problem of easy blockage:

[0006] The size of the pump body of the reclaimed water recovery and reuse system suitable for families is small, and the diameter of the nozzle is even smaller, only about 1-2 mm, which is easy to be blocked

However, if a filter screen with a gap of about 1-2mm is added upstream of the pump body, it will cause increased loss of water pressure, thereby affecting the work of the jet pump.

It is also difficult to clean the filter

[0007] 2. Due to the easy blockage of the nozzle, the problem of preventing the reclaimed water from flowing back into the tap water pipe network:

[0008] Reclaimed water is non-drinking water, so it can only be used to flush the toilet or similar functions, so it cannot enter the tap water pipe network, otherwise it will cause water pollution, so in order to prevent the return of reclaimed water caused by nozzle blockage, an additional check valve is required. This increases installation space and cost

[0009] 3. The problem of low efficiency:

[0010] Due to the small size of the ordinary pump body, the efficiency is low, the time to fill the water tank is too long, the mixing ratio and efficiency of reclaimed water need to be improved
