[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] The embodiment of this application provides a multi-media filter tank for purified water production. Refer to Figures 1 to 3 A multi-media filter tank for purified water production includes a tank body 1. A sealed tank cover 2 is detachably installed at the top of the tank body 1. A water filter plate 3 is fixedly installed at a position near the bottom inside the tank body 1. At the same time, a connecting shaft 4 is rotatably arranged on the sealed tank cover 2. A first support rod 5 is fixedly connected to a position near the top of the connecting shaft 4. A second support rod 6 is sleeved at a position near the bottom of the connecting shaft 4, and the second support rod 6 is in contact with the plate surface of the water filter plate 3. A screw scraper 7 is arranged between the first support rod 5 and the second support rod 6. The two ends of the screw scraper 7 are respectively fixedly connected to the free end of the first support rod 5 and the free end of the second support rod 6, and the outer side of the screw scraper 7 is in contact with the inner wall of the tank body 1.

[0025] A feed pipe 13 is fixedly connected to the sealed tank cover 2. A discharge pipe 14 is fixedly connected to the side wall of the tank body 1 near the bottom. The discharge pipe 14 is arranged at the same horizontal level as the water filter plate 3, and the medium on the water filter plate 3 can be discharged through the discharge pipe 14. A water inlet pipe 15 is fixedly connected to the side wall of the tank body 1 near the top. A drain pipe 16 and a maintenance pipe 17 are fixedly connected to the bottom of the tank body 1. Both the maintenance pipe 17 and the drain pipe 16 are arranged below the discharge pipe 14.

[0026] The top of the sealed tank cover 2 is provided with a driving mechanism 8 for driving the connecting shaft 4 to rotate forward and reversely, and the driving mechanism 8 can be a motor. When cleaning the inner cavity of the tank body 1, various media in the tank body 1 are discharged, and then the cleaning liquid and the agent are injected into the tank body 1. The connecting shaft 4 is driven to rotate by controlling the driving mechanism 8, thereby driving the first support rod 5 and the second support rod 6 to rotate, and then driving the spiral scraper 7 to rotate along the inner wall of the tank body 1. The cleaning liquid and the agent are mixed and stirred by the rotation of the spiral scraper 7, the impact force of the cleaning liquid is increased, and the agent is fully mixed to achieve sterilization and disinfection of the inner wall of the tank body 1; at the same time, the rotation of the spiral scraper 7 scrapes off the attachments produced by the inner wall of the tank body 1, so that the cleaning of the inner wall of the tank body 1 is more thorough; in addition, the remaining scattered media falling on the water filter plate can be concentrated and pushed to the discharge pipe 14 for discharge through the rotation of the second support rod 6. The thickness of the spiral scraper 7 gradually decreases as it approaches the inner wall of the tank body 1 , so that the spiral scraper 7 has a better cleaning effect on the inner wall of the tank body 1 .

[0027] When using the multi-media filter tank of the present application, the water inlet pipe 15 is connected to the water source pipe, the drainage pipe 16 is connected to the subsequent device pipe, the feed pipe 13 is opened by loosening the bolts, and the filter media are fed from the feed pipe 13 into the inner cavity of the tank body 1 layer by layer from coarse to fine, thereby forming a multi-layer filter layer, and the filter medium is supported by the water filter plate 3, and then the feed pipe 13 is blocked, so that the multi-media filter tank of the present application is in a sealed state.

[0028] The raw water is transported to the tank body 1 through the water inlet pipe 15, and the impurities in the water are adsorbed and filtered by the filter medium. The filtered water seeps to the bottom of the inner cavity of the tank body 1 through the water filter plate 3 and is transported to the subsequent device through the drainage pipe 16. When the filter medium needs to be replaced, the discharge pipe 14 is opened and the filter medium in the inner cavity of the tank body 1 is discharged from the discharge pipe 14, and then the discharge pipe 14 is blocked, and then a new filter medium is added to the tank body 1.

[0029] The maintenance pipe 17 is provided to enable maintenance and repair of the water filter plate 3. In addition, a lifting ring is fixed on the sealed tank cover 2. By connecting the lifting device to the lifting ring and removing the connecting bolts between the tank body 1 and the sealed tank cover 2, the sealed tank cover 2 can be lifted, so that the internal components of the tank body 1 can be inspected and replaced.

[0030] Furthermore, an annular sliding groove 11 is also formed on the inner wall of the tank body 1. The free end of the second support rod 6 is slidably inserted into the annular sliding groove 11. A limiting vertical groove 12 is communicated with the annular sliding groove 11. The extending direction of the limiting vertical groove 12 is parallel to the height direction of the tank body 1, and the free end of the second support rod 6 can be inserted into the limiting vertical groove 12. The connecting shaft 4 is a threaded rod, and the second support rod 6 is threadedly sleeved outside the connecting shaft 4. At the same time, the spiral scraper 7 is made of plastic material, so that the spiral scraper 7 can be deformed while having a certain hardness.

[0031] By providing the annular sliding groove 11 and the limiting vertical groove 12, the contraction and expansion of the spiral scraper 7 can be realized. Specifically, when the multi-media filter tank is in normal use, the spiral scraper 7 is contracted under the sealing tank cover 2. When the inner wall of the tank body 1 needs to be cleaned, first, various media in the tank body 1 are discharged, and then the driving mechanism 8 is used to drive the connecting shaft 4 to rotate. Under the limiting action of the limiting vertical groove 12, the rotation of the connecting shaft 4 can drive the second support rod 6 to slide downward along the limiting vertical groove 12 until the free end of the second support rod 6 is located in the annular sliding groove 11.

[0032] When the free end of the second support rod 6 is located in the annular sliding groove 11, continue to drive the connecting shaft 4 to rotate. At this time, the free end of the second support rod 6 moves around the annular sliding groove 11, thereby driving the spiral scraper 7 to rotate to achieve cleaning. After the inner wall of the tank body 1 is cleaned, the driving mechanism 8 is used to drive the second support rod 6 to rotate to the connection part of the annular sliding groove 11 and the limiting vertical groove 12. At this time, the staff can control the free end of the second support rod 6 in the tank body 1 through the discharge pipeline 14 to limit the horizontal movement of the second support rod 6, and then drive the connecting shaft 4 to rotate again, so that the second support rod 6 slides along the limiting vertical groove 12, thereby realizing the storage of the spiral scraper 7.
