Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy pipelines, in particular to a water conservancy pipeline with a filtering structure. Background Art

[0002] Water users who have requirements for water quality will set up some filtering devices to filter impurities in the water in the pipes when using water pipes to transport water. For example, a filter net will be set up inside the pipe for filtering, and the filter net will be cleaned after filtering for a period of time to maintain the filtering function of the filter net.

[0003] When cleaning the filter screen, most of the existing water conservancy pipelines with filtering functions use a device to scrape off the impurities on the filter screen to achieve the purpose of cleaning. For example, a Chinese invention patent discloses an anti-blocking pipeline for water conservancy projects (publication number: CN111720660A). When in use, the liquid flows in the pipeline body. Because the blocking device is designed, the liquid cannot flow into the branch pipe and can only continue to flow in the pipeline body. Then it flows to the filter screen, and the liquid flows through the through hole, while the impurities in the liquid are blocked outside. At the same time, when the fluid flows into the filter ball, it will flush the impact wheel, thereby driving the filter ball to rotate. The rotation of the filter ball will scrape off the impurities stuck in the through hole to prevent the filter hole from being blocked. For example, a water conservancy pipeline with filtering function disclosed in a Chinese invention patent The engineering pipeline (publication number: CN117926899A) is equipped with a filter cone, a rotating shaft, rotating blades, and a cleaning block. When water resources are transported, the water will be filtered when passing through the filter cone, and the water passing through the filter cone will cause the rotating blades to rotate when flowing through the rotating blades. When the rotating blades rotate, the cleaning block will be driven to rotate through the rotating shaft. When the cleaning block rotates, the impurities blocked in the filter holes of the filter cone will be brushed out to prevent the filter cone from being blocked. There are some defects in using a device to clean the filter. For example, in a pipe with a small inner diameter, it is impossible to install more parts to clean impurities on the filter. For example, too many parts will increase the failure rate. For example, if the parts are damaged, it will be more troublesome to perform maintenance and repairs in the later stage.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-6 A water conservancy pipeline with a filtering structure includes a filtering pipeline 1, on which a solenoid valve 1, a tee pipe 2 and a tee pipe 3 are provided, a drain pipe 6 is provided on the tee pipe 2, and a solenoid valve 2, 7 is provided on the drain pipe 6, and also includes a water inlet pipeline 8 connected to the filtering pipeline 1, a tee pipe 3, 9, a tee pipe 4, 10 and a solenoid valve 3, 11 are provided on the water inlet pipeline 8, a drain pipe 2, 12 is provided on the tee pipe 4, 13 is provided on the drain pipe 2, and also includes a backwashing pipe 14 for connecting the tee pipe 2 and the tee pipe 3, 9, and a solenoid valve 4 is provided on the backwashing pipe 14. Valve five 15, a filter screen 4 is arranged on the filter pipe 1, and the filter screen 4 is arranged at one end of the filter pipe 1 near the water inlet pipe 8. The arrangement order of tee one 2, tee two 3, solenoid valve one 5, tee three 9, tee four 10 and solenoid valve three 11 on the filter pipe 1 and the water inlet pipe 8 is: solenoid valve one 5, tee one 2, tee two 3, tee four 10, solenoid valve three 11 and tee three 9. The filter pipe 1, the water inlet pipe 8, the drain pipe one 6, the drain pipe two 12 and the backwash pipe 14 are all connected to each other, and the tee two 3 and the tee four 10 are respectively arranged on both sides of the filter screen 4.

[0025] The present utility model has three modes when in use. The water flows through the water inlet pipe 8 to the filter pipe 1. The three modes are switched by controlling the opening and closing states of the solenoid valve 1 5, the solenoid valve 2 7, the solenoid valve 3 11, the solenoid valve 4 13 and the solenoid valve 5 15. The three modes are described in detail below during use.

[0026] Mode 1 is the water source delivery mode, such as Figure 4As shown, in this mode, the three-way pipe 2 and the solenoid valve 3 11 are in the open state, the solenoid valve 2 7, the solenoid valve 4 13 and the solenoid valve 5 15 are in the closed state, and the water flows from the water inlet pipe 8 to the filter pipe 1. When the water flows through the filter screen 4, the filter screen 4 can filter the impurities in the water flow. This mode can normally deliver water.

[0027] Mode 2 is backwash mode, such as Figure 5 As shown, in this mode, the filter 4 can be backwashed. At this time, the solenoid valve three 11, the solenoid valve one 5 and the solenoid valve two 7 are in the closed state, the solenoid valve five 15 and the solenoid valve four 13 are in the open state, and the water flows through the water inlet pipe 8 to the backwash pipe 14, and then flows through the backwash pipe 14 to the filter pipe 1, and then flows from the filter pipe 1 to the water inlet pipe 8, and then flows through the water inlet pipe 8 to the drain pipe two 12, and the backwash water source is discharged through the drain pipe two 12. When the water source flows from the filter pipe 1 to the water inlet pipe 8, the impurities attached to the filter 4 are located on the side close to the water inlet pipe 8. Under the action of the water backwash, the impurities enter the water inlet pipe 8 with the water flow, and are finally discharged through the drain pipe two 12, thereby achieving the effect of cleaning the impurities on the filter 4.

[0028] Mode 3 is the cleaning backwash water mode, such as Figure 6 As shown, in this mode, the water used for backwashing and not filtered in the filter pipe 1 can be discharged, thereby ensuring that the water discharged from the filter pipe 1 meets the use standards. In this mode, the solenoid valve 1 5 and the solenoid valve 4 13 are in the closed state, the solenoid valve 5 15, the solenoid valve 3 11 and the solenoid valve 2 7 are in the open state. At this time, the water flow is divided into two branches. The first branch water flow flows from the water inlet pipe 8 to the filter pipe 1, from the filter pipe 1 to the drain pipe 1 6, and finally discharged through the drain pipe 1 6. The second branch water flow flows from the water inlet pipe 8 to the backwash pipe 14, from the backwash pipe 14 to the filter pipe 1, and finally from the filter pipe 1 to the drain pipe 1 6, and finally discharged through the drain pipe 1 6, thereby discharging the water in the filter pipe 1 that has been backwashed and not filtered, preventing the unfiltered water from being transported to the water-using equipment through the filter pipe 1 when performing mode 1 after performing mode 3.

[0029] In addition, when in mode 1, since the solenoid valve 5 15 is closed, the backwash pipe 14 is in a sealed state. Therefore, after mode 3, the water inside the backwash pipe 14 will not follow the water flow in the water inlet pipe 8 or the filter pipe 1 into the filter pipe 1.

[0030] In another embodiment, solenoid valve 1 5 , solenoid valve 2 7 , solenoid valve 3 11 , solenoid valve 4 13 and solenoid valve 5 15 are all connected to the Internet of Things control system. Through the control of the Internet of Things system, corresponding modes can be set in different time periods according to user needs, and the opening duration of each mode can be adjusted to meet user needs.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
