Description

Technical Field

[0001] This utility model relates to the field of multi-media filters, and in particular to a multi-media filter for water treatment. Background Technology

[0002] A multi-media filter is a device used for water treatment that removes impurities such as suspended solids, colloids, and microorganisms from water by using different types of filter media. This type of filter typically consists of several layers of filter media with different densities and particle sizes, arranged from top to bottom as: a coarse filter layer, a fine filter layer, and a high-precision filter layer.

[0003] Multi-media filters work by using filter media of different densities and particle sizes to intercept and adsorb impurities in the water. When water passes through the filter, larger particles are first intercepted by the upper coarse filter media, while smaller particles pass through the coarse filter layer to the lower fine filter layer, and finally reach the fine filter layer, thus achieving efficient removal of impurities from the water.

[0004] In practical use, larger particles and suspended solids tend to accumulate in the filter media of multi-media filters, which slows down the water flow rate within the filter cartridge. This reduced flow rate affects filtration efficiency, increases pressure loss in the water treatment system, and consequently reduces the overall system efficiency. Furthermore, clogging of the filter media can cause uneven pressure distribution within the filter, further impacting filtration performance and potentially requiring frequent backwashing to remove accumulated substances, increasing maintenance costs and operational complexity. Utility Model Content

[0005] The main objective of this invention is to provide a multi-media filter for water treatment, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A multi-media filter for water treatment includes a support, a filter tank, an inlet, an outlet, and a sealing cap. The filter tank is installed on the upper end of the support, the inlet and outlet are respectively installed on the upper and lower parts of the side wall of the filter tank, and the sealing cap is fixed to the upper end of the filter tank by bolts.

[0008] A servo motor is installed at the upper end of the sealing cover. The output end of the servo motor passes through the sealing cover and is connected to a stirring rod. A fixed cylinder is installed at the lower end of the sealing cover and is connected to a centrifugal filter cylinder through the fixed cylinder. The side wall of the centrifugal filter cylinder has a through hole. A rotating cylinder is connected to the stirring rod. The rotating cylinder is connected to rotating blades through a fixing component. The outer end of the rotating blades is provided with a cleaning strip. The cleaning strip removes impurities from the through hole to prevent blockage. The rotation of the rotating cylinder and rotating blades drives the liquid inside the centrifugal filter cylinder to rotate, realizing the liquid centrifugation operation and the first filtration operation.

[0009] The centrifugal filter cartridge is equipped with a bottom cylinder at its lower end, and the bottom cylinder has a first filter layer, a second filter layer, and a third filter layer arranged sequentially from top to bottom. The bottom cylinder has a drain port at its lower end, which extends out of the filter tank. The second filtration operation is achieved through the first filter layer, the second filter layer, and the third filter layer.

[0010] In a preferred embodiment of this utility model, the liquid inlet is sealed and fixed on the filter tank, and the liquid inlet extends into the fixed cylinder, and the liquid inlet transports the liquid into the fixed cylinder and the centrifugal filter cylinder.

[0011] In a preferred embodiment of this utility model, the sealing cover is fixed to the filter tank by bolts, nuts and washers, the servo motor is fixed to the sealing cover by bolts, and the servo motor and the sealing cover are mechanically sealed.

[0012] In a preferred embodiment of this utility model, the fixed cylinder and the centrifugal filter cylinder are fixed by bolts and nuts, and multiple through holes are distributed in a ring on the centrifugal filter cylinder. The centrifugal filter cylinder, the bottom cylinder and the drain port are designed as an integral unit.

[0013] In a preferred embodiment of this utility model, the drain outlet passes through the filter tank and is sealed thereto, and a valve is provided on the drain outlet;

[0014] In a preferred embodiment of this utility model, the first filter layer, the second filter layer, and the third filter layer are PP cotton filter layer, ceramic filter layer, and activated carbon filter layer, respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By employing centrifugal operation technology and a combination of multiple filter layers (including PP cotton, ceramic, and activated carbon), highly efficient filtration of liquids can be achieved, ensuring that the purity of the effluent reaches an ideal state. The integrated design of the centrifugal filter cartridge, bottom cylinder, and drain port not only ensures the compactness of the entire structure but also guarantees the integrity of its functions and efficient operation.

[0017] Furthermore, the stirring rod and rotating blades can rotate automatically through precise control of the servo motor, simplifying the entire filtration process. The cleaning bar is responsible for periodically removing impurities from the through-holes, effectively preventing clogging and ensuring the filter operates continuously and effectively.

[0018] After centrifugation, the liquid undergoes further deep filtration through multiple filter layers, thereby enhancing the filtration effect. This multi-layered filtration mechanism not only effectively removes suspended particles, organic matter, and harmful chemicals from the liquid but also ensures the purity and safety of the final effluent, meeting the needs of various industrial and domestic water applications.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 - Figure 5As shown, a multi-media filter for water treatment includes a support 1, a filter tank 2, an inlet 3, an outlet 4, and a sealing cap 5. The filter tank 2 is mounted on the upper part of the support 1, while the inlet 3 and outlet 4 are respectively mounted on the upper and lower parts of the side wall of the filter tank 2. The sealing cap 5 is firmly fixed to the upper part of the filter tank 2 by bolts. A servo motor 6 is installed on the upper part of the sealing cap 5, and the output end of the servo motor 6 passes through the sealing cap 5 and is connected to a stirring rod 16. A fixed cylinder 7 is installed on the lower part of the sealing cap 5, and a centrifugal filter cylinder 8 is connected through the fixed cylinder 7. Multiple through holes 9 are opened on the side wall of the centrifugal filter cylinder 8. A rotating cylinder 12 is connected to the stirring rod 16, and rotating blades 14 are connected to the rotating cylinder 12 through a fixing member 13. The outer end of the rotating blades 14 is provided with a cleaning strip 15, which is responsible for cleaning impurities at the through holes 9 to prevent clogging. The rotation of the rotating cylinder 12 and the rotating blades 14 drives the liquid inside the centrifugal filter cylinder 8 to rotate, thereby realizing the centrifugation of the liquid and completing the first filtration operation.

[0027] A bottom cylinder 10 is installed at the lower end of the centrifugal filter cartridge 8. Inside the bottom cylinder 10, from top to bottom, are arranged a first filter layer 17, a second filter layer 18, and a third filter layer 19. A drain port 11 is provided at the lower end of the bottom cylinder 10, extending out of the filter tank 2. A second filtration operation is achieved through the first filter layer 17, the second filter layer 18, and the third filter layer 19. An inlet port 3 is installed on the filter tank 2 in a sealed manner, extending into the fixed cylinder 7. The inlet port 3 delivers liquid to both the fixed cylinder 7 and the centrifugal filter cartridge 8.

[0028] The sealing cap 5 is fixed to the filter tank 2 using a combination of bolts, nuts, and washers. The servo motor 6 is also fixed to the sealing cap 5 with bolts, ensuring a mechanical seal between the servo motor 6 and the sealing cap 5. The fixed cylinder 7 is fixed to the centrifugal filter cylinder 8 using a combination of bolts and nuts. Multiple through holes 9 are distributed in a ring on the side wall of the centrifugal filter cylinder 8. The centrifugal filter cylinder 8, the bottom cylinder 10, and the drain port 11 are integrated into a single design, ensuring a compact structure and functional integrity.

[0029] The drain port 11 passes through and is sealed to the filter tank 2. A valve is provided on the drain port 11 to control the discharge of liquid. The first filter layer 17, the second filter layer 18, and the third filter layer 19 are respectively a PP cotton filter layer, a ceramic filter layer, and an activated carbon filter layer. These filter layers are arranged in sequence to complete the deep filtration of the liquid and ensure the purity of the effluent.

[0030] The operating procedure is as follows: Open the valve at the inlet 3 to ensure that the liquid can flow into the filter tank 2. Start the servo motor 6 to make the stirring rod 16 and the rotating blade 14 start rotating. The liquid enters the fixed cylinder 7 and the centrifugal filter cylinder 8 through the inlet 3. The rotating blade 14 drives the liquid to rotate inside the centrifugal filter cylinder 8, realizing the first filtration operation. The rotation of the rotating cylinder 12 and the rotating blade 14 drives the liquid inside the centrifugal filter cylinder 8 to rotate, and impurities are swept away by the cleaning strip 15 to prevent the through hole 9 from being blocked. The liquid flowing out through the through hole 9 can be discharged from the outlet 4, or it can be allowed to reach the through hole 9 and flow back to the bottom cylinder 10 for filtration again. The liquid after centrifugation enters the first filter layer 17, the second filter layer 18 and the third filter layer 19 through the bottom cylinder 10. The liquid passes through the PP cotton filter layer, the ceramic filter layer and the activated carbon filter layer in sequence to complete the deep filtration. The filtered liquid is discharged through the drain port 11. The discharge speed and flow rate of the liquid are controlled by the valve on the drain port 11.

[0031] Disassembly and Cleaning Process: Close the valve at the inlet 3 to stop liquid flow. Turn off the servo motor 6 to stop the rotation of the stirring rod 16 and the rotating blade 14. Loosen the bolts, nuts, and gaskets securing the sealing cover 5. Remove the sealing cover 5 to expose the servo motor 6 and the stirring rod 16. Disassemble the connecting bolts and nuts between the fixed cylinder 7 and the centrifugal filter cylinder 8. Remove the rotating cylinder 12 and the rotating blade 14, paying attention to the cleanliness of the cleaning strip 15. Disassemble the bottom cylinder 10 and remove the first filter layer 17, the second filter layer 18, and the third filter layer 19. Clean or replace the PP cotton filter layer, the ceramic filter layer, and the activated carbon filter layer. Clean the through holes 9 of the centrifugal filter cylinder 8 to ensure there is no blockage. Clean the interior of the fixed cylinder 7 and the bottom cylinder 10 to ensure no impurities remain. Reassemble the filter in the reverse order of disassembly. Ensure all components are installed in place and securely fixed. Reconnect the servo motor 6 and the sealing cover 5, ensuring a good seal. Restart the equipment and check for leaks or abnormalities. After confirming that the equipment is operating normally, resume normal use.
