Description

Technical Field

[0001] The utility model relates to the technical field of rainwater collection and reuse treatment equipment, in particular to a pre-treatment and lifting device suitable for collected rainwater. Background Art

[0002] Initial rainwater is generally more polluted. When it rains, dissolved gases, dissolved or suspended solids, heavy metals, and bacteria in the air will enter it. Surface pollutants mainly come from the erosion of the ground by rainfall. Therefore, surface sediments are the main source of pollutants. At the same time, there are some dead branches and leaves in the rainwater. In the era of water conservation, rainwater is collected and recycled. However, if the initial rainwater is directly mixed with the water source, it will pollute the water source. If the initial rainwater is directly discharged, it will also affect the natural environment. Therefore, the initial rainwater needs to be pre-treated. In addition, due to the deep laying depth of the front-end rainwater pipe network, it is very easy to cause the back-end water storage tank to be buried deeper, resulting in deep foundation pit construction, which increases construction costs. The existing pretreatment equipment on the market does not meet the needs. In this regard, we have proposed a pretreatment lifting device suitable for rainwater collection. Utility Model Content

The left side of the upper part of the device box 1 is a rainwater filtration area 4, and a water collector 8 is installed inside the rainwater filtration area 4. The right side of the upper part of the device box 1 is a rainwater lifting area 5. A rainwater lifting pipe 13 is installed in the device box 1, and a lifting water pump 12 is installed at the bottom of the rainwater lifting pipe 13. The lower part of the device box 1 is a water storage tank 7, and a connecting rod type liquid level gauge 11 is provided in the water storage tank 7. The upper part of the rainwater lifting area 5 is provided with a rainwater lifting area inspection port 3. The device box 1 is A partition 6 is provided between the rainwater filtration area 4 and the rainwater lifting area 5. A connecting rod liquid level gauge 11 controls the start and stop of the lifting water pump 12. When the liquid level meets the starting conditions of the lifting water pump 12, the water pump starts, otherwise the water pump stops. A water inlet 18 is provided above the rainwater filtration area 4, and a rainwater filtration area inspection port 2 is also provided on the rainwater filtration area 4. A check valve 14, an elbow 15 and a ball valve 16 are respectively installed on the rainwater lifting pipe 13, and the other end of the rainwater lifting pipe 13 is connected to a water outlet 17;

[0022] In this embodiment, the rainwater flows through the rain divider 9 to the rain outlet 19, and is screened out by the grid mesh 22. Large-volume debris remains in the basket filter 10 inside the water collector, and the relatively pure rainwater enters the water storage tank 7 at the bottom of the device. The basket filter 10 can be lifted regularly to clean up large-volume debris.

[0023] Example 2

[0024] refer to Figures 1 to 3Example 2 is described. This embodiment further illustrates Example 1 and includes a water collector 8. A basket filter 10 is installed around the upper end of the water collector 8. A filter handle 20 is installed on the upper part of the basket filter 10. A plurality of rain outlets 19 are provided on the outer ring of the basket filter 10. A rain divider 9 is installed in the middle of the upper end of the water collector 8. The rain divider 9 is conical. A grid net 22 is installed on each of the plurality of rain outlets 19. The outer filter net 21 of the rain divider is located in the middle of the basket filter 10. When naturally suspended, it is conical and fits tightly with the rain divider 9. Rainwater flows through the rain divider 9 to the rain outlet 19 and is screened by the grid net 22. Large-volume debris remains in the basket filter 10 inside the water collector 8. The relatively pure rainwater filtered by the water collector 8 enters the water storage tank 7.

[0025] In this embodiment, the rain distributor 9 installed in the middle of the water collector 8 flows to the rain distribution port 19 on the outer circle of the basket filter 10. The rain distribution port 19 is installed with a grille net 22. With the interception of the grille net 22, relatively pure rainwater enters the water storage tank in the lower part of the device, and large-volume debris remains in the basket filter 10 inside the water collector.

[0026] In specific applications, when the bottom equipment of this device is in use, the collected rainwater enters the pretreatment lifting device from the water inlet 18, first passes through the rainwater filtration area 4, and flows to the rain outlet 19 on the outer circle of the basket filter 10 through the rain divider 9 installed in the middle of the water collector 8. The rain outlets 19 are all installed with grid nets 22. With the interception of the grid nets 22, the relatively pure rainwater enters the water storage tank in the lower part of the device, and the large volume of debris remains in the basket filter 10 inside the water collector; after the rainwater is pretreated in the filtration area, the connecting rod liquid level gauge 11 installed in the water storage tank is used to control the start and stop of the lifting pump 12 in the water tank. When the liquid level meets the conditions, the pretreated rainwater is lifted to the outlet 17 for subsequent treatment. In addition, it is necessary to regularly open the inspection port 2 of the rainwater filtration area to clean the large volume of debris accumulated inside the basket filter 10 to avoid affecting the filtering effect of the pretreatment lifting device. The cleaning method is: first open the inspection port 2 of the rainwater filtration area, then pull out the filter handle 20 installed on the side wall of the basket filter 10, and then lift the basket filter 10 upward to separate it from the water collector 8. After pouring the large volume of debris accumulated in the basket filter 10 to the designated position, put the basket filter 10 back into the water collector 8, retract the filter handle 20, and close the inspection port 2 of the rainwater filtration area.
