DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] As Figures 1 - 2As shown in the figure, there is a backwash resin tank. One side of the top of the resin tank 1 is provided with a flushing inlet. Inside the resin tank 1, there is a flushing pipe 3. The top of the flushing pipe 3 is communicated with the flushing inlet. The flushing pipe 3 extends into the inside of the resin tank 1 to the inside of the exchanger bed 9. The lower end of the flushing pipe 3 is provided with a flushing plate 8 with a circular structure. The upper end of the flushing plate 8 is provided with a plurality of nozzles. Inside the resin tank 1, there are also a plurality of screen meshes 7. Outside the resin tank 1, at the position of the screen meshes 7, there are a plurality of vibration motors 6. The top of the flushing pipe is connected and communicated with the flushing inlet at the top of the resin tank. The flushing pipe 3 extends downward into the resin tank 1 until it reaches the inside of the exchanger bed 9. The lower end of the flushing pipe 3 is provided with a flushing plate 8 with a circular structure. The upper end of the flushing plate is provided with a plurality of nozzles for evenly distributing the flushing water. The upper end is provided with a plurality of nozzles for evenly spraying the flushing water onto the exchanger bed. Outside the resin tank, at the position of the screen meshes 7, there are a plurality of vibration motors for vibrating the screen meshes to help clean the exchanger bed and the quartz sand layer.

[0020] When it is necessary to flush the resin tank, flushing water is injected into the resin tank through the flushing inlet. The flushing water reaches the flushing plate 8 through the flushing pipe 3 and is evenly sprayed onto the exchanger bed 9 through a plurality of nozzles. At the same time, a plurality of vibration motors 6 are started, causing the screen meshes 7 to start vibrating, and then driving the exchanger bed 9 and the quartz sand layer 13 to vibrate. In this way, water enters through the flushing plate 8 and the second drain port 11 to flush the inside of the resin tank, and the flushing water is discharged from the first drain port 4.

[0021] In a preferred solution, a plurality of installation steps 101 are provided inside the resin tank 1. The screen meshes 7 are arranged on the installation steps 101, and a plurality of screen meshes 7 are arranged inside the exchanger bed 9 and the quartz sand layer 13. An elastic support ring 701 is provided on the installation steps 101. The screen meshes 7 are fixedly connected to the installation steps 101 through the elastic support ring 701. The cross-section of the screen meshes 7 is a V-shaped structure, and the V-shaped grooves of the screen meshes 7 face the inner wall of the resin tank 1. A plurality of installation steps 101 are provided inside for supporting the screen meshes 7. It is arranged at the position outside the resin tank 1 corresponding to the screen meshes 7. It is used to vibrate the screen meshes 7 and drive the exchanger bed 9 and the quartz sand layer 13 to vibrate.

[0022] When cleaning, the screen meshes 7 start vibrating under the action of the vibration motors 6. The vibration of the screen meshes 7 drives the exchanger bed 9 and the quartz sand layer 13 to vibrate, thereby effectively vibrating and cleaning these two layers. At the same time, the flushing water is evenly sprayed onto the exchanger bed 9 through the flushing pipe 3 and the flushing plate 8. Combined with the vibration, the water can better penetrate the exchanger bed 9 and the quartz sand layer 13, achieving a more thorough cleaning effect.

[0023] In a preferred embodiment, a second drain port 11 is provided at the lower end of the resin tank 1. A first filter screen 14 is provided inside the second drain port 11, and the aperture of the first filter screen 14 is 2 - 3 mm. The second drain port 11 is provided at the lower end for draining water and reverse flushing water intake. The aperture of the first filter screen 14 being 2 - 3 mm can effectively block the passage of the quartz sand layer 13 particles, and impurity particles smaller than the quartz sand will be discharged from the second drain port 11.

[0024] The second drain port 11 can not only be used to discharge the wastewater after cleaning, but also be used as an inlet during the reverse flushing process. In the normal working state, the second drain port 11 is used to discharge the water after flushing treatment, while during reverse flushing, the second drain port 11 can be used as an inlet to introduce high-pressure water to perform reverse flushing on the inside of the resin tank, cleaning the exchange agent layer 9 and the quartz sand layer 13.

[0025] In a preferred embodiment, a first drain port 4 is provided on the side of the upper end of the resin tank 1, and a third electric valve 401 is provided on the first drain port 4. During the water pressure flushing, the water containing impurities will be discharged from the first drain port 4 at the top. During the flushing process, the third electric valve 401 is opened to allow the flushing water to carry impurities and be discharged from the first drain port, thereby realizing the cleaning of the inside of the resin tank.

[0026] In a preferred embodiment, a water outlet 15 is provided on one side of the resin tank 1. The water outlet pipe is bent downward towards the lower end of the resin tank 1 and is close to the bottom of the resin tank 1. A second filter screen 16 is sleeved on the water outlet pipe, and the aperture of the second filter screen 16 is 1 - 2 mm. The water outlet pipe is bent downward towards the lower end of the resin tank 1 and is close to the bottom of the resin tank 1. A second filter screen 16 is sleeved on the water outlet pipe for filtering impurities in the discharged water. The aperture of the second filter screen 16 being 1 - 2 mm can effectively block the passage of smaller particle impurities.

[0027] The water after filtration treatment will be discharged from the water outlet 15. In the normal use state, the water treated by the resin tank is discharged through the water outlet pipe and filtered by the second filter screen 16 to remove smaller particle impurities, ensuring the cleanliness of the discharged water quality.

[0028] In a preferred embodiment, a fourth electric valve 12 is provided at the lower end of the second drain port 11. The fourth electric valve 12 controls the switch for flushing and draining.

[0029] In a preferred embodiment, a second electric valve 301 is provided at the flushing port outside the flushing pipe 3. The second electric valve 301 controls the switch of the flushing water.

[0030] In a preferred embodiment, a plurality of observation glasses 10 are further provided on the resin tank 1, and a maintenance port 5 is further provided above the resin tank 1. The observation glasses 10 are used to observe the inside of the resin tank 1, and the maintenance port 5 facilitates personnel to perform maintenance on the inside of the resin tank 1.

[0031] When it is necessary to rinse the resin tank 1, the first electric valve 201 and the fifth electric valve 1501 are closed, and the second electric valve 301 and the fourth electric valve 12 are opened to inject water into the resin tank 1. At the same time, multiple vibration motors 6 start to vibrate, and the screen 7 starts to vibrate under the action of the vibration motors 6. The screen 7 drives the exchanger layer 9 and the quartz sand layer 13 to vibrate. Under the condition that water enters through the flushing plate 8 and the second drain port 11, the inside of the exchanger layer 9 and the quartz sand layer 13 of the resin tank 1 is rinsed. The rinsing water is discharged from the first drain port 4. After rinsing for a period of time, the second electric valve 301 is closed, the second drain port 11 stops supplying water, and the second drain port 11 starts to drain water. After the second drain port 11 drains the water inside, the rinsing is completed.
