Description

A rainwater collection electronically controlled liquid level discarding filter device

technical field

The utility model relates to the field of sewage treatment equipment, in particular to an electronically controlled liquid level discarding filter device for rainwater collection. the

Background technique

The deterioration of the water environment is mainly caused by the mixed flow of our domestic sewage and rainwater; while our sewage treatment plant is a constant treatment unit (without storing pools to be treated), during sunny periods, domestic sewage flows into the sewage treatment plant, Discharge after treatment. However, when the rainfall is heavy, the rainwater becomes a tool for carrying domestic sewage, taking away the domestic sewage and discharging it to the rivers around the city, polluting the water environment, and greatly reducing the efficiency of sewage treatment. Relevant experts have demonstrated this: sewage treatment The processing efficiency of the plant is only 10%. the

In the 1960s and 1970s, developed countries improved the water environment, and their rainwater collection and utilization technology was mature and their equipment was advanced; Water standards are also convenient for equipment installation, and play an important role in more effectively promoting rainwater collection and utilization, controlling floods, reducing mixed flow of rain and sewage, and protecting the water environment. the

The utility model is achieved through the following technical solutions:

A rainwater collection electronically controlled liquid level discarding filter device, including a discarding chamber and a sedimentation chamber, characterized in that: the upper ends of the discarding chamber and the sedimentation chamber are passed through by a filter inlet pipe, the On the filter water inlet pipe are respectively the rainwater discarding outlet located in the discarding chamber and the water outlet located in the sedimentation chamber. A floating ball limiting net is arranged directly below the rainwater discarding outlet in the discarding chamber. A floating ball is arranged in the position net, a filter basket is erected under the floating ball limiting net, a drainage device is provided at the bottom of the discarding cavity, and a retention tank is erected under the water outlet in the sedimentation cavity. A fine filter basket is erected below the retention tank, and the filter material is filled in the fine filter basket, through holes are distributed at the bottom of the retention tank, and a drain is provided on the outer wall of the sedimentation cavity, so A corresponding liquid level switch is provided in the waste flow chamber at the water inlet position of the filter water inlet pipe. the

The discarding cavity and the sedimentation cavity are respectively a box, or both are arranged in the same box and separated by a partition, and the upper ends of the boxes are respectively provided with box covers. the

The drainage device is a water outlet or a sewage pipe, the pipe connected to the water outlet is provided with a manual discharge valve, the sewage pipe is connected to a liquid flow pipe, and is controlled by a liquid level switch and a time relay. the

The filter material is sand or carbon. the

A booster pump is provided in the fine filter basket, and a liquid level control probe is provided on the side wall of the sedimentation chamber above the retention tank. the

A dosing machine is provided above the inner water outlet of the sedimentation chamber, and through holes are distributed at the bottom of the discharge pipe of the dosing machine, and the material is mixed with fine filtered water through the through holes. the

The principle is: the electric valve is used to control the water level of the collection pool, the floating ball controls the water inlet pipe, the initial rainwater is separated to the waste flow chamber, and the sewage is pumped out through the liquid level control, and the filter in the waste flow chamber roughly filters the rainwater, Larger lumps from storm sewers collect, regularly cleaned out. When the initial rainwater is discarded, the power of the sewage pump is controlled by the liquid level switch to pump out the precipitated sewage; and the working time is controlled by the time relay, and the initial rainwater is discharged by the sewage pump; the water inlet pipe flows through the water distribution plate to the fine filter basket, Sand or carbon material is filtered, and under the action of water level difference, the rainwater flows into the sedimentation chamber through the sand carbon filter, and the purified rainwater flows into the storage tank through the pipeline to be used. The process improves water quality. When the purified rainwater flows into the storage tank through the pipeline, it can be discharged from the liquid flow pipe to the rainwater pipeline when it reaches a certain water level. the

The utility model has the advantages of:

The utility model integrates the automatic control of water volume control, waste flow, fine filtration and accelerated filtration of rainwater, and utilizes the water level difference for natural water purification process, reduces manual management costs, and is easy to install. the
