Description

Technical Field

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

[0002] Multi-media filters primarily utilize the filtration effects of different media such as quartz sand and activated carbon to remove suspended solids, colloids, organic matter, and other impurities from water through interception and adsorption. When water enters from the top of the filter, impurities are trapped as it passes through different media layers, and the purified water flows out from the bottom. It is commonly used in industrial water treatment, such as reverse osmosis pretreatment; it is also used in domestic drinking water treatment for preliminary filtration of raw water; and it can also be used for the purification of swimming pool water, circulating cooling water, etc.

[0003] Multi-media filters typically consist of a tank, a water distribution system, filter media layers, and a water collection system. The water distribution system collects the filtered water and evenly distributes it out of the filter. A backwashing system is also included. The tank serves as a container, holding the filter media and the liquid to be treated. The water distribution system ensures that the incoming water is evenly distributed across the filter cross-section, preventing short-circuiting. The filter media layers, such as quartz sand and activated carbon, remove impurities through interception and adsorption. The water collection system collects the filtered water and evenly distributes it out of the filter. The backwashing system removes impurities trapped in the filter media layers through backwashing, restoring filtration performance.

[0004] In existing technologies, fixed water distributors can only distribute water in a fixed location, resulting in uneven water flow and localized accumulation of impurities in the distributor, which clogs the nozzles and prevents the distributor from distributing water properly. To address this issue, a multi-media filter is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-media filter, which aims to improve the problem that the existing fixed water distributor can only distribute water in a fixed position, resulting in uneven water flow, local accumulation of impurities in the water distributor, clogging of the water distributor nozzles, and thus preventing the water distributor from distributing water normally.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-media filter includes a tank, inside which is a sand-prevention assembly for holding quartz sand. Multiple mounting brackets are fixedly connected to the inner wall of the tank. A mounting plate is fixedly connected to the top of each mounting bracket. A drive motor is fixedly connected to the bottom of the mounting plate. A gear ring is slidably connected to the inner wall of the mounting plate. A drive column is fixedly connected to the drive end of the drive motor. A drive gear is fixedly connected to the outer wall of the drive column. The outer wall of the drive gear meshes with the outer wall of the gear ring.

[0008] As a further description of the above technical solution:

[0009] The anti-sand leakage component includes a sand baffle plate. The outer wall of the sand baffle plate is fixedly connected to the inner wall of the tank. The inner wall of the sand baffle plate is provided with multiple water outlet holes. The bottom of each of the multiple water outlet holes is fixedly connected with a filter nozzle. The inner wall of each of the multiple filter nozzles is provided with a water outlet groove.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the tank is fixedly connected to an anthracite coal seam, the inner wall of the tank is fixedly connected to a sand baffle, the inner wall of the toothed ring is fixedly connected to a water distributor, and the outer wall of the water distributor is fixedly connected to multiple nozzles.

[0012] As a further description of the above technical solution:

[0013] A layer of quartz sand is fixedly connected to the inner wall of the tank, and a layer of gravel is fixedly connected to the inner wall of the tank.

[0014] As a further description of the above technical solution:

[0015] An activated carbon layer is fixedly connected to the inner wall of the tank, and a manganese sand layer is fixedly connected to the inner wall of the tank.

[0016] As a further description of the above technical solution:

[0017] The top of the tank is fixedly connected to a filter inlet, and the bottom of the filter inlet is fixedly connected to multiple inlet pipes.

[0018] As a further description of the above technical solution:

[0019] A backwash outlet is fixedly connected to the outer wall of the tank, and a backwash pump is fixedly connected to the outer wall of the backwash outlet.

[0020] As a further description of the above technical solution:

[0021] A backwash inlet is fixedly connected to the bottom of the tank, a backwash pump is fixedly connected to the outer wall of the backwash inlet, a water inlet is fixedly connected to the bottom of the tank, and a regulating valve is fixedly connected to the outer wall of the water inlet.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the backwash pump is started, and the backwash pump draws the cleaning solution into the inner wall of the tank through the backwash inlet. At this time, the water drawn in is sprayed from the nozzles onto the inner walls of the surrounding filter layers through the water distributor. During the spraying process, the drive motor starts, which drives the drive column to rotate. The rotation of the drive column drives the drive gear to rotate, which in turn drives the gear ring to rotate. The rotation of the gear ring drives the water distributor to rotate. The rotation of the water distributor allows the nozzles to spray water evenly onto the surrounding layers. During the rotation, the water flow direction can be continuously changed, reducing the accumulation of impurities in the water distributor and reducing the chance of clogging. It can also make the water evenly distributed in different areas, avoiding excessive or insufficient water in some areas, and improving the filtration effect.

[0024] 2. In this utility model, during the filtration process, water flows out through the water outlet holes on the surface of the baffle plate, and then flows out through the water outlet groove on the outer wall of the filter nozzle, further reducing the pressure of the water flow on the quartz sand layer. A gravel layer is also provided at the bottom of the quartz sand layer. The gravel layer can provide stable support for the quartz sand, disperse the water flow pressure, and reduce the possibility of quartz sand directly contacting the filter plate and leaking out, thereby preventing the leakage of quartz sand from causing a decrease in the effect of the filtration device in subsequent use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 2 to 4 This utility model provides an embodiment of a multi-media filter, including a tank 1. The tank 1 has a sand-prevention component inside to prevent quartz sand from leaking out during backwashing and filtration due to water flow, ensuring the stable operation and filtration effect of the filter device. Multiple fixing brackets 2 are fixedly connected to the inner wall of the tank 1. The multiple fixing brackets 2 serve to support the fixing plate 3, ensuring that the fixing plate 3 is stably installed inside the tank 1. The fixing plate 3 is fixedly connected to the top of the multiple fixing brackets 2. The fixing plate 3 provides an installation position for components such as the drive motor 4 and the gear ring 7, ensuring the stability of each component during operation.

[0033] A drive motor 4 is fixedly connected to the bottom of the fixed disk 3. The drive motor 4 provides power for the rotation of the water distributor 8, enabling the nozzle 9 to spray water evenly, thereby achieving a better backwashing effect. A toothed ring 7 is slidably connected to the inner wall of the fixed disk 3. The toothed ring 7 rotates under the drive of the drive gear 5, which in turn drives the water distributor 8 to rotate, so that the nozzle 9 can spray water evenly to the surrounding layers. A drive column 6 is fixedly connected to the drive end of the drive motor 4. The drive column 6 transmits the power of the drive motor 4 to the drive gear 5, ensuring that the drive gear 5 can rotate stably. The drive gear 5 is fixedly connected to the outer wall of the drive column 6. The drive gear 5 meshes with the toothed ring 7. By rotating itself, it drives the toothed ring 7 to rotate, thereby realizing the rotation of the water distributor 8. The outer wall of the drive gear 5 and the outer wall of the toothed ring 7 are meshed with each other. This connection method can accurately transmit power and ensure the stable rotation of the water distributor 8.

[0034] The inner wall of the tank 1 is fixedly connected to an anthracite layer 10, which can adsorb and filter impurities in the water, improving the filtration effect. The inner wall of the tank 1 is fixedly connected to a sand baffle 11, which can not only block quartz sand, but also allow water to flow out through the water outlet 26 on its surface, reducing the pressure of water flow on the quartz sand layer 12. The inner wall of the toothed ring 7 is fixedly connected to a water distributor 8, which rotates under the drive of the toothed ring 7 to evenly distribute the cleaning liquid to each nozzle 9 for spraying. The outer wall of the water distributor 8 is fixedly connected to multiple nozzles 9, which spray the cleaning liquid onto the inner wall of each surrounding filter layer to achieve backwashing of the filter layer. The inner wall of the tank 1 is fixedly connected to a quartz sand layer 12, which performs fine filtration of water and removes fine particulate impurities in the water.

[0035] A gravel layer 13 is fixedly connected to the inner wall of the tank 1. The gravel layer 13 provides stable support for the quartz sand, disperses the water flow pressure, reduces the possibility of leakage due to direct contact between the quartz sand and the filter plate, and ensures the stability of the quartz sand layer 12. An activated carbon layer 14 is fixedly connected to the inner wall of the tank 1. The activated carbon layer 14 can adsorb odors and some harmful substances in the water, further improving the water quality. A manganese sand layer 15 is fixedly connected to the inner wall of the tank 1. The manganese sand layer 15 can remove metal ions such as iron and manganese in the water, improving the water quality.

[0036] Reference Figures 1 to 3 The anti-sand leakage component includes a sand baffle plate 11. The outer wall of the sand baffle plate 11 is fixedly connected to the inner wall of the tank 1. The sand baffle plate 11 is used to block the quartz sand and prevent it from being washed out by the water flow during backwashing and filtration. The inner wall of the sand baffle plate 11 is provided with multiple water outlet holes 26. The multiple water outlet holes 26 allow water to flow through, reducing the pressure of the water flow on the quartz sand layer 12 and preventing the quartz sand from leaking out due to the impact of the water flow. The bottom of each of the multiple water outlet holes 26 is fixedly connected with a filter nozzle 24. The filter nozzle 24 further guides the water flow, making the water flow more even. The inner wall of the multiple filter nozzles 24 is provided with a water outlet groove 25. The water outlet groove 25 increases the outflow area of ​​the water flow, further reducing the pressure of the water flow on the quartz sand layer 12 and effectively preventing the quartz sand from leaking out.

[0037] A filter inlet 21 is fixedly connected to the top of the tank 1. The filter inlet 21 is used to introduce the water to be filtered into the tank 1 to start the filtration process. Multiple inlet pipes 18 are fixedly connected to the bottom of the filter inlet 21. The multiple inlet pipes 18 distribute the water evenly into the tank 1 to make the filtration more thorough. A backwash outlet 22 is fixedly connected to the outer wall of the tank 1. The backwash outlet 22 is used to discharge the cleaning liquid after backwashing to ensure the cleanliness of the inside of the tank 1. A backwash water pump 23 is fixedly connected to the outer wall of the backwash outlet 22. The backwash water pump 23 provides power to extract the cleaning liquid after backwashing from the tank 1 to complete the backwashing process.

[0038] A backwash inlet 19 is fixedly connected to the bottom of the tank body 1. The backwash inlet 19 is used to introduce the cleaning fluid required for backwashing and to provide a water source for backwashing. A backwash pump 20 is fixedly connected to the outer wall of the backwash inlet 19. The backwash pump 20 draws the cleaning fluid into the inner wall of the tank body 1 to start the backwashing process. A water inlet 16 is fixedly connected to the bottom of the tank body 1. The water inlet 16 is used to introduce the water to be filtered and is the inlet for water to enter the filter. A regulating valve 17 is fixedly connected to the outer wall of the water inlet 16. The regulating valve 17 can adjust the flow rate and pressure of the incoming water to ensure the stable operation of the filtration process.

[0039] Working principle: When backwashing is required on the inner wall of tank 1, backwash pump 20 is started. Backwash pump 20 draws cleaning fluid into the inner wall of tank 1 through backwash inlet 19. At this time, the drawn water is sprayed onto the inner walls of the surrounding filter layers by nozzles 9 through water distributor 8. During the spraying process, drive motor 4 is started. The start of drive motor 4 drives drive column 6 to rotate. The rotation of drive column 6 drives drive gear 5 to rotate. The rotation of drive gear 5 drives gear ring 7 to rotate. The rotation of gear ring 7 drives water distributor 8 to rotate. The rotation of water distributor 8 allows nozzles 9 to spray water evenly on the surrounding layers. This prevents incomplete cleaning caused by uneven water distribution by water distributor 8. Then backwash outlet pump 23 is started. Backwash outlet pump 23 draws out the cleaning fluid after cleaning through backwash outlet 22.

[0040] During routine backwashing or water filtration, the quartz sand layer 12, due to its fine texture, is easily washed out during the backwashing and filtration process. At this time, during the filtration process, water will flow out through the water outlet 26 on the surface of the baffle plate 11, and then through the water outlet groove 25 on the outer wall of the filter nozzle 24, further reducing the pressure of the water flow on the quartz sand layer 12. A gravel layer 13 is also provided at the bottom of the quartz sand layer 12. The gravel layer 13 can provide stable support for the quartz sand, disperse the water flow pressure, and reduce the possibility of quartz sand directly contacting the filter plate and leaking out, thereby preventing the leakage of quartz sand from causing a decrease in the effect of the filtration device in subsequent use.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
