A pulse water distribution device

Abstract

The invention protects a pulse type water distribution device, which includes a water distribution tank and a tube type automatic water inlet and outlet device. The tube type automatic water inlet and outlet includes a water inlet pipe, a flexible pipe, a water outlet pipe and a water retaining structure. The water outlet pipe is located at the bottom of the water distribution tank, and the hole passes through; the water inlet pipe passes through the hose and the water outlet pipe, and the gravity is less than or equal to the buoyancy it receives. The water retaining structure is arranged in the water inlet pipe and can be opened and closed with the change of the position of the water inlet pipe. During a water storage period, the water inlet pipe floats up with the rise of the liquid level in the tank. When it floats up to the highest height, the water retaining structure is closed, and the liquid level is higher than the front end of the water inlet pipe. The water pipe begins to sink due to the increase of its own weight, and the water retaining structure is opened. When the water inlet pipe sinks to the bottom of the water distribution tank, the liquid level is lower than the nozzle of the water inlet pipe, and a drainage period is completed. This cycle forms a pulsed water distribution. The invention has the advantages of simple structure, high efficiency and stable performance, and can realize automatic adjustment of hydraulic power, adjust the flow of water inflow to artificial wetlands, and control the cycle of water inflow.

Description

technical field [0001] The invention belongs to the technical field of water pollution treatment devices, in particular to water distribution technology for water pollution treatment. Background technique [0002] With the continuous improvement of rural living standards, the discharge of rural domestic sewage has gradually increased. In view of the characteristics of scattered rural households, scattered discharge of rural domestic sewage, large fluctuations in water volume and water quality, and serious water pollution (especially rural toilet sewage), decentralized rural domestic sewage treatment technologies such as constructed wetlands are low in construction and operating costs, and easy to operate and manage. It is widely used due to the advantages of good purification effect and so on. During the application of these technologies, the periodicity and stability of influent largely determine the pollution load and treatment effect of treatment facilities. [0003] Th...

AI Technical Summary

Problems solved by technology

Existing pulse water distribution devices are generally controlled by complex liquid level sensing devices and electromagnetic control valves, using power devices such as water pumps or gates, and performing periodic water distribution through manual operation or program remote control. Usually the system is relatively complicated, which leads to High failure rate, difficult maintenance and management, not suitable for rural domestic sewage treatment

There are also some siphon pulse water distribution systems. Although there is no complicated liquid level sensing device and electromagnetic control valve control, when the water inflow is small flow, it often produces continuous overflow and cannot form a siphon, thus losing the function of pulse water distribution. , cannot run stably
