Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a multi-media filter for pure water equipment. Background Technology

[0002] Multi-media filters utilize two or more filter media to pass water through a certain thickness of granular or non-granular material, thereby effectively removing suspended impurities and clarifying the water. This process allows more opportunities for particles in the water to collide with sand particles, causing flocculation, suspended solids, and sand particles to adhere to each other. Impurities in the water are trapped in the filter media layer, resulting in clarified water.

[0003] Traditional multi-media filters typically have their filter media laid directly and tightly inside the filter, layered according to material. However, the inlet pipe is located in the middle of the tank and directly faces the media layer. As the water flow has an impact force during injection, and this impact force increases with pressure, it can cause significant localized impact on the media layer, affecting its distribution density. Furthermore, the concentrated water flow can lead to excessively high flow velocity, which can easily affect the filtration effect.

[0004] Therefore, a multi-media filter for pure water equipment is proposed to solve the above problems. Utility Model Content

The end of the return pipe away from the water pump is fixedly connected to and connected to the bottom of one side of the tank. The water outlet of the water pump is connected to the tank and is fixedly connected to and connected to the tank. The water pump is electrically connected to the controller.

[0009] As a preferred technical solution of this utility model, the mounting base plate has a plurality of locking holes around its outer ring, and the bottom of the fixing ring is provided with a plurality of locking blocks. The shape of the locking blocks corresponds to that of the locking holes, and each locking block is rotatably connected to the fixing ring through a corresponding connecting rod.

[0012] 1. This utility model, through the setting of the anti-impact guide plate and the diversion hole on it, can effectively block and reduce the impact of the water flow entering the tank, effectively reducing the impact force of the water flow.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Example 1

[0023] Please refer to the following: Figure 1-3 The multi-media filter of the pure water equipment of this utility model includes a tank 1, a bottom bracket 2 detachably mounted at the bottom of the tank 1, an inlet pipe 3 at the top of the tank 1, an outlet pipe 13 at the bottom of the bottom bracket 2, an anti-rush guide plate 4 fixedly connected to the top of the inner wall of the tank 1, a plurality of diversion holes 16 opened at the bottom of the anti-rush guide plate 4, a motor 5 fixedly connected to the middle of the top of the tank 1, the output end of the motor 5 passes through the tank 1 and is fixedly connected to a rotating rod 6, the bottom end of the rotating rod 6 passes through the anti-rush guide plate 4 and is fixedly connected to a flow-dispersing plate 7, a fixing ring 8 fixedly connected to the middle of the inner wall of the tank 1, and a filter assembly 9 detachably mounted on the fixing ring 8.

[0024] The filter assembly 9 includes an assembly barrel 91, with a mounting base plate 92 fixedly connected to the bottom of the assembly barrel 91. The mounting base plate 92 is detachably connected to the fixing ring 8. The assembly barrel 91 is provided with a top filter layer 93, an activated carbon adsorption layer 94 at the bottom of the top filter layer 93, a coarse sand layer 95 at the bottom of the activated carbon adsorption layer 94, and a bottom filter layer 96 at the bottom of the coarse sand layer 95.

[0025] The inner wall of the bottom trailer 2 is provided with a mesh frame 10, which is fixedly connected to the inner wall of the bottom trailer 2. Several detectors 11 are provided on the top of the mesh frame 10. A controller 12 is fixedly connected to the side wall of the tank body 1. The detectors 11 are electrically connected to the controller 12.

[0026] A water pump 14 is installed on the top of the tank 1 away from the water inlet pipe 3. The water inlet of the water pump 14 is fixedly connected to and connected to a return pipe 15. The end of the return pipe 15 away from the water pump 14 is fixedly connected to and connected to the bottom of the side of the tank 1. The water outlet of the water pump 14 is connected to the tank 1. The water pump 14 is electrically connected to the controller 12.

[0027] Specifically, when using this utility model, water is fed into the tank 1 through the inlet pipe 3. After entering the tank 1, the water first contacts the annular baffle of the anti-impact guide plate 4, which initially blocks and reduces the force of the water flow. Then, the water flows to the bottom of the anti-impact guide plate 4 and falls through the diversion hole 16. At the same time, the motor 5 is started to drive the rotating rod 6 to rotate, so that the flow-dispersing plate 7 rotates continuously under the transmission action to strike and disperse the water flow flowing down the anti-impact guide plate 4, further reducing the impact force of the water flow. This allows the water flow to fall more gently and evenly onto the filter assembly 9, effectively avoiding the situation where the water column directly impacts the filter layer and causes damage to the filter layer during long-term use.

[0028] The water filtered at the bottom of the tank 1 is detected by the detector 11 on the mesh frame 10, and the result is fed back to the controller 12. When the water quality does not meet the requirements, the water pump 14 is started to draw the water out through the return pipe 15 and send it back to the top of the tank 1 for repeated filtration. After the water quality is qualified, the water is sent out through the outlet pipe 13.

[0029] Example 2

[0030] Please refer to the following: Figure 1-5 The multi-media filter for pure water equipment proposed in this utility model has a mounting base plate 92 with a plurality of locking holes 19 around its outer ring. A fixing ring 8 has a plurality of locking blocks 20 at its bottom, the locking blocks 20 corresponding to the shapes of the locking holes 19. Each locking block 20 is rotatably connected to the fixing ring 8 through a corresponding connecting rod. The mounting base plate 92 has a plurality of positioning insertion holes 17 around its outer ring, each positioning insertion hole 17 being located between two corresponding locking holes 19. A positioning insertion rod 18 is provided between every two locking blocks 20. Each positioning insertion rod 18 is fixedly connected to the bottom of the fixing ring 8 and is inserted into the corresponding positioning insertion hole 17.

[0031] The working principle is that by inserting the positioning rod 18 into the corresponding positioning hole 17, the filter assembly 9 can be quickly positioned and installed with the fixing ring 8. When the mounting base plate 92 is in contact with the fixing ring 8, each locking block 20 passes through the corresponding locking hole 19. By turning each locking block 20 clockwise by 90°, the locking block 20 is in contact with the bottom of the mounting base plate 92 and locked, thereby connecting and fixing the filter assembly 9 with the fixing ring 8.

[0032] When the filter media in the filter assembly 9 needs to be replaced, remove the bottom support 2, then support the filter assembly with the bracket, and then rotate each locking block 20 counterclockwise 90° to the corresponding position of the locking hole 19. Then lower the support frame so that the filter assembly 9 can be lowered and detached from the tank 1. Then install the replacement filter assembly 9 according to the above operation, which effectively improves the replacement efficiency of multiple filter media.

[0033] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
