Description

Technical Field

[0001] The utility model relates to the field of rainwater collectors, in particular to a rainwater collector with a filtering function. Background Art

[0002] A rainwater collector is a device that filters rainwater during rainwater collection. It uses the gravity flow characteristics of rainwater to separate garbage and water in the rainwater, and the separated water is then discharged into the reservoir to achieve the purpose of separating and collecting rainwater. This solution specifically relates to a rainwater collector with a filtering function. The existing rainwater collector changes the flow direction through an internal elbow, and flows around the inner wall of the rainwater collector in a vortex. Under the action of centrifugal force, silt and fallen leaves settle downward and are discharged through the sewage outlet. However, in this process, silt and fallen leaves will flow together with a certain amount of rainwater, causing a large amount of rainwater to be lost. At the same time, the filtering filter is easily blocked due to the attachment of silt and fallen leaves after long-term use, affecting the filtering effect. Utility Model Content

[0003] The main purpose of the utility model is to provide a rainwater collector with a filtering function, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A rainwater collector with a filtering function comprises an upper tank body, a lower tank body is installed on the top of the upper tank body, a water inlet is fixedly welded on one side passing through the upper tank body, a clean water pipe is fixedly welded on one side passing through the lower tank body near the lower end, a return pipe is fixedly welded on the top of the clean water pipe, a solenoid valve is fixedly installed on one side passing through the top of the clean water pipe and located on the return pipe, a sewage outlet is fixedly welded on the other side passing through the lower tank body near the upper end, limiting blocks are fixedly welded on both sides and the inner walls of the front and rear ends of the lower tank body, and the same filter mesh frame is arranged on the tops of the four limiting blocks.

[0006] As a further solution of the utility model, a sealing gasket is provided between the upper tank body and the lower tank body, and the upper tank body and the lower tank body are fixedly connected by bolts and nuts.

[0007] As a further solution of the utility model, the end of the reflux pipe is communicated with the interior of the lower tank body.

[0008] As a further solution of the utility model, the filter screen frame is arranged to be inclined toward one side of the sewage outlet, and the filter screen frame is sleeved with the lower tank body.

[0009] As a further solution of the utility model, the return pipe, the filter frame and the sewage outlet are located on the same straight line.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model provides a filter frame and a limit block, and uses the limit block to support the filter frame. When rainwater mixed with mud and fallen leaves passes through the filter frame, the filter frame intercepts the mud and fallen leaves. After being intercepted, the mud and fallen leaves roll down the upper surface of the filter frame to be discharged into the sewage outlet, and the rainwater falls into the bottom of the lower tank body and is then discharged through the clean water pipe. When the solenoid valve is closed, the rainwater in the clean water pipe flows back to the lower tank body through the reflux pipe, and the water flow impacts the filter frame, and the mud and water attached to the filter frame are washed into the sewage outlet, thereby avoiding the filter frame from being blocked after long-term use. At the same time, it is easy to separate the mud and fallen leaves mixed in the rainwater, reduce the loss of rainwater, and achieve a better separation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 4As shown, a rainwater collector with a filtering function comprises an upper tank body 1, a lower tank body 2 is installed on the top of the upper tank body 1, a water inlet 3 is fixedly welded on one side passing through the upper tank body 1, a clean water pipe 4 is fixedly welded on one side passing through the lower tank body 2 near the lower end, a return pipe 5 is fixedly welded on the top of the clean water pipe 4, a solenoid valve 6 is fixedly installed on the top of the clean water pipe 4 and on one side of the return pipe 5, a sewage outlet 7 is fixedly welded on the other side passing through the lower tank body 2 near the upper end, and limiting blocks 10 are fixedly welded on both sides and the inner walls of the front and rear ends of the lower tank body 2, and the same filter mesh frame 9 is arranged on the tops of the four limiting blocks 10.

[0019] A sealing gasket 8 is arranged between the upper tank body 1 and the lower tank body 2, and the upper tank body 1 and the lower tank body 2 are fixedly connected by bolts and nuts. The bolts and nuts are arranged to facilitate the connection of the upper tank body 1 and the lower tank body 2, and the sealing gasket 8 is used to enhance the sealing of the connection between the upper tank body 1 and the lower tank body 2 to prevent the rainwater collector from leaking during use.

[0020] The end of the reflux pipe 5 is connected to the interior of the lower tank body 2 . When the solenoid valve 6 is closed, the water in the clean water pipe 4 flows back into the lower tank body 2 through the reflux pipe 5 .

[0021] The filter frame 9 is inclined toward one side of the sewage outlet 7 and is sleeved with the lower tank body 2. The filter frame 9 is provided to filter rainwater falling from the upper tank body 1 and to intercept sediment and fallen leaves.

[0022] The return pipe 5 , the filter screen frame 9 and the sewage outlet 7 are located in the same straight line. When rainwater flows back into the lower tank 2 through the return pipe 5 , the water flow impacts the filter screen frame 9 , and washes the mud and fallen leaves attached to the filter screen frame 9 into the sewage outlet 7 .

[0023] It should be noted that the utility model is a rainwater collector with filtering function, which uses a limit block 10 to support the filter frame 9, and uses a sealing gasket 8 to improve the sealing after the upper tank body 1 and the lower tank body 2 are connected, and the end of the clean water pipe 4 is connected to the water tank;

[0024] When in use, rainwater mixed with silt and fallen leaves enters the upper tank body 1 through the water inlet 3. When the rainwater mixed with silt and fallen leaves passes through the filter frame 9, the silt and fallen leaves are intercepted by the filter frame 9. Under the impact of the water flow, the silt and fallen leaves are washed into the sewage outlet 7 along with part of the rainwater and discharged. Most of the filtered rainwater passes through the filter frame 9 and falls into the bottom of the lower tank body 2, and then is discharged through the clean water pipe 4, and is discharged into the water storage tank through the water inlet pipe 4.

[0025] When the solenoid valve 6 is closed, the filtered rainwater flows into the clean water pipe 4, and then flows back to the lower tank 2 through the reflux pipe 5. Under the impact of the water flow, the mud and fallen leaves attached to the filter frame 9 are washed away by the water flow and discharged through the drain outlet 7 along with the water flow, thus preventing the filter frame 9 from being blocked during continuous use.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
