2results about How to "Reduce water flow rate" patented technology

This invention relates to the field of wastewater treatment technology, and more particularly to an urban domestic wastewater treatment device including a treatment pump station. The top of the outer arc surface of the treatment pump station is provided with a flange inlet, and the bottom of the inner arc surface of the treatment pump station near the flange inlet is connected to a conical flow guide plate. The upper surface of the conical flow guide plate is provided with an inlet in the middle. The conical flow guide plate is a double-layered structure with an arched end inside. Through a special structural design, the water flow is guided to form a slow flow state, providing sufficient reaction time for the coalescence of tiny oil droplets. This promotes the fusion of emulsified oil droplets and dispersed oil droplets to form large oil droplets. Utilizing the physical property that the density of oil is less than that of water, the oil droplets can naturally float to the surface and form a stable floating oil layer. The entire oil-water separation process does not require additional power and can be completed solely by gravity, effectively improving the oil-water separation efficiency while reducing the energy consumption and maintenance costs of the device.

A crop ecological nutritive water generator belongs to the technical field of water purification equipment. A water segregator is arranged on the top of a shell, a water outlet filter is arranged on the upper portion in the shell and sleeved on the outer side of a water inlet pipe, the water segregator comprises an inner cavity and an outer cavity which are annularly sleeved, a water inlet and a water outlet are processed on the water segregator, the water inlet is communicated with the inner cavity, and the water outlet is communicated with the outer cavity. The bottom of the inner cavity is fixedly connected with the top of the water inlet pipe, the bottom of the water inlet pipe is provided with a water inlet filter, a water outlet is provided with a water outlet pipe, the water outlet pipe is divided into a plurality of water outlet branch pipes, and the water outlet branch pipes are provided with magnetized water outlet devices. The crop ecological nutritive water generator solves the problems that when a crop ecological nutritive water generator in the prior art is actually used, the diameter of a water flow channel is narrowed when water flow passes through a magnetic field, the pressure difference between a water inlet end and a water outlet end is unbalanced, and water pipes are broken or water leaks at the joint after long-term use, eliminates the risk of pipeline burst, and meanwhile enhances the magnetic field intensity.
