Description

rainwater collection filter

technical field

The utility model relates to a rainwater collection device, in particular to a rainwater collection filter.

Background technique

During the rainfall process, due to the existence of dust, coal dust, smog, fiber impurities and other suspended particles and bacteria and viruses in the air, the concentration of pollutants in the first rainwater is relatively high. Therefore, when collecting rainwater, the pollutants Concentrated rainwater is excluded and only clean rainwater is collected. The existing selective rainwater harvesting device has complex structures and has deficiencies.

Utility model content

The purpose of the utility model is to provide a rainwater collection filter with simple structure and convenient use, which can eliminate rainwater with high pollutant concentration and only collect and filter clean rainwater, so as to solve the deficiencies in the prior art.

The technical scheme adopted in the utility model is: a rainwater collection filter, including a rainwater collection filter bucket and a bucket cover, a water inlet hole is provided in the center of the bucket cover, and a water inlet cavity communicated with the water inlet hole is provided in the center of the filter bucket , the bottom of the water inlet chamber is a sewage outlet and is provided with a valve device for sewage discharge. A filter device is provided at the bottom of the filter barrel. Has a water outlet.

The further improvement of the utility model also lies in:

The control device includes a rubber plug arranged at the sewage outlet, the upper end of the rubber plug is connected with a floating ball in the water inlet chamber through a wire, and the rubber plug is driven by the buoyancy of the floating ball to plug the sewage outlet.

The control device is a valve installed at the sewage outlet.

The valve is a solenoid valve.

The filtering device is bamboo charcoal or medical stone.

The filtering device also includes a filter net.

Compared with the prior art, the utility model has the following beneficial effects:

1. The utility model can realize the removal of rainwater with high pollutant concentration and only collect and filter clean rainwater by setting a sewage valve device at the sewage outlet;

2. The valve device is set as a rubber plug connected by a wire, a floating ball, a valve, and an electromagnetic valve, and its structure is simple and easy to use.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in the accompanying drawings, the rainwater collection filter of the present utility model includes a rainwater collection filter bucket 1 and a bucket cover 2. The center of the bucket cover 2 is provided with a water inlet hole 3, and the upper part of the filter bucket 1 is provided with a water inlet. The water inlet chamber 4 connected with the hole 3, the bottom end of the water inlet chamber 4 is a sewage outlet 5 and is provided with a valve device for sewage discharge. Connected with a floating ball 8 located in the water inlet chamber, the rubber plug 6 is driven by the buoyancy of the floating ball 8 to plug the sewage outlet 5, and a filtering device 9 is provided at the bottom of the filter barrel 1, and the filtering device 9 includes a filter screen 10 , and bamboo charcoal or medical stone located between the filter screen 10, the barrel wall, above the filter device 9, the barrel wall is provided with a water outlet 11.

The utility model is mainly used for collecting and filtering rainwater when it is large. When the utility model is used to collect and filter rainwater, the sewage outlet is opened without being blocked by the rubber stopper, and the collected rainwater enters the water inlet chamber through the water inlet hole of the barrel cover, and the rainwater with a large concentration of pollutants is discharged through the sewage outlet. As the volume of rainwater in the water inlet chamber continues to increase, the floating ball rises, driving the rubber plug at the sewage outlet, and the rubber plug moves upward to block the drain outlet. The water at the lower end of the water inlet chamber enters the filter device, and the rainwater is filtered by the filter device. Enter the water storage tank from the water outlet above.

The valve device of the utility model can also be a valve or an electromagnetic valve installed at the sewage outlet.

It can be seen from the above that the utility model is provided with a rubber plug at the sewage outlet, and the upper end of the rubber plug is connected with a floating ball through a line, and the rubber plug is driven by the buoyancy of the floating ball to plug the sewage outlet at the lower end of the filter barrel, so that the pollutants with a large concentration can be eliminated The rainwater only collects and filters the rainwater that cleans the rainwater; and the structure is simple and easy to use.

The foregoing embodiments are only two embodiments of the utility model, and are not used to limit the implementation and scope of rights of the utility model. All equivalent changes and modifications made according to the content described in the utility model application patent protection scope shall include Within the patent scope of the utility model application.
