Description

Technical Field

[0001] This utility model relates to the field of fine filter technology, and more specifically, to a multilayer active media fine filter. Background Technology

[0002] In today's industrial production and daily life, the demand for water purification is extremely widespread and the requirements are constantly increasing. In the water treatment industry, whether it is the purification of water sources in waterworks, the treatment of industrial circulating water, or the deep treatment of wastewater in sewage treatment plants, efficient and reliable fine filters are needed to remove impurities such as suspended solids, colloids, organic matter, and heavy metal ions from the water in order to meet different water quality standards and usage requirements.

[0003] However, existing fine filters cannot be disassembled, making it inconvenient to replace the filter media. Furthermore, the filter media does not have a separate filter bed, which easily leads to mixed-layer phenomena and reduces the utilization rate of the filter media.

[0004] For example, Chinese patent CN210945210U discloses a multi-media precision filter. This structure, through a series of structural modifications, makes the device easier to disassemble and replace the filter media. Furthermore, during backwashing, the filter media is less prone to mixing, thus improving the utilization rate of the filter media.

[0005] However, in actual use, after the cylinder drives the top cover on the outer shell to open, the top cover is still at the top of the outer shell. This makes the operating space between the outer shell and the top cover very limited, which brings great inconvenience to the operator when changing the packing. In view of this, this utility model proposes a multi-layer active media fine filter. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-layer active media fine filter to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer activated media fine filter, comprising a base plate and a housing mounted on the base plate. A top cover is detachably mounted on the top of the housing. A 360-degree annular water distributor is installed inside the top cover, and a water inlet pipe is provided on the surface of the top cover. An exhaust pipe is connected to the 360-degree annular water distributor. One end of the water inlet pipe extends into the interior of the top cover and communicates with the 360-degree annular water distributor. The exhaust pipe extends to the exterior of the top cover, and an exhaust valve is installed on the exterior of the exhaust pipe. A 360-degree annular water collector is provided at the bottom of the inner cavity of the housing. The surface of the housing... The top cover is equipped with a water outlet pipe, and a vent pipe is connected to the 360-degree annular water distributor. One end of the water outlet pipe extends into the interior of the outer shell and is connected to the 360-degree annular water distributor. The vent pipe extends to the exterior of the outer shell, and a vent valve is installed on the exterior of the vent pipe. Inside the outer shell, at the top of the 360-degree annular water distributor, a packed filter bed containing multiple layers of active media is installed. The outer wall of the top cover is connected to a packing port. The surface of the top cover is provided with two observation windows, and an inlet and outlet pressure gauge is installed on one side of the observation windows. A status control box is installed on one side of the inlet and outlet pressure gauges.

[0008] As can be seen, the water is evenly distributed into the shell by the water distributor, and then filtered and purified by the multi-layer active media packing inside the packing filter bed. Finally, it is collected by the 360-degree annular water collector and flows out as usable water through the outlet pipe.

[0009] To facilitate the assembly and disassembly of the top cover and the outer shell, preferably, a connecting plate is fixedly installed on the upper surface of the outer shell and the lower surface of the top cover. Several bolts are threaded onto each of the two connecting plates, and they are detachably connected by the bolts.

[0010] To provide ample operating space for packing replacement, preferably, the top of the upper cover is provided with a lifting and moving structure, which includes an L-shaped bracket. The L-shaped bracket is movably mounted on the top of the base plate and located on one side of the outer shell. Two electric push rods are provided on the top of the L-shaped bracket, and the output ends of both electric push rods are fixedly connected to the upper cover. Two mounting slots are formed on the surface of the base plate. A lead screw is rotatably mounted inside one mounting slot, and a slide rod is fixedly mounted inside the other mounting slot. A threaded block and a slider are respectively provided on the outside of the lead screw and the slide rod, and a motor is provided at one end of the lead screw. A movable seat is provided on the surface of the base plate and at the bottom of the L-shaped bracket. The motor is fixedly mounted at one end of the base plate, and the output end of the motor is fixedly connected to the lead screw inside one of the mounting slots. The threaded block is located outside the lead screw and is threadedly connected to the lead screw. The slider is slidably connected to the slide rod. The threaded block and the slider are both fixedly mounted on the bottom of the movable seat, and the movable seat is fixedly connected to the bottom of the L-shaped bracket.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By setting up a lifting and moving structure, the electric push rod drives the upper cover to extend upwards, separating the upper cover from the outer shell. The motor drives the lead screw to rotate, and the threaded block uses the moving seat to drive the L-shaped bracket. The slider slides on the slide rod, causing the L-shaped bracket to move away from the outer shell on the base plate. The L-shaped bracket drives the lifted upper cover to move synchronously, thereby exposing the multi-layer active media packing in the packing filter bed inside the outer shell, providing operators with a good operating space for changing the packing.

[0013] 2. By introducing the water to be filtered into the 360-degree annular water distributor inside the top cover through the inlet pipe, the 360-degree annular water distributor evenly distributes the water inside the outer shell, avoiding local water flow concentration, and allowing the water to flow evenly through the packing filter bed below, ensuring consistent filtration effect. When the water flows through the packing filter bed containing multiple layers of active media, the multiple layers of active media achieve water purification and filtration. The filtered water reaches the bottom of the outer shell and is collected by the 360-degree annular water collector, and flows out through the outlet pipe, improving the water purification and filtration effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] As attached Figure 1-5 The multi-layer activated media filter shown includes a base plate 1 and a housing 2 mounted on the base plate 1. A top cover 3 is detachably mounted on the top of the housing 2. A 360-degree annular water distributor 4 is installed inside the top cover 3, and an inlet pipe 5 is provided on the surface of the top cover 3. An exhaust pipe 6 is connected to the 360-degree annular water distributor 4. One end of the inlet pipe 5 extends into the interior of the top cover 3 and is connected to the 360-degree annular water distributor 4. The exhaust pipe 6 extends to the outside of the top cover 3, and an exhaust valve 23 is installed on the outside of the exhaust pipe 6. A 360-degree annular water collector 7 is provided at the bottom of the inner cavity of the housing 2, and an outlet pipe 8 is provided on the surface of the housing 2. The annular water distributor 7 is connected to a vent pipe 9. One end of the outlet pipe 8 extends into the interior of the outer shell 2 and is connected to the 360-degree annular water distributor 7. The vent pipe 9 extends to the exterior of the outer shell 2, and a vent valve 24 is installed on the exterior of the vent pipe 9. Inside the outer shell 2, at the top of the 360-degree annular water distributor 7, a packing filter bed 10 containing multiple layers of active media packing is installed. The outer wall of the top cover 3 is connected to a packing port 11. The surface of the top cover 3 is provided with two observation windows 25, and an inlet and outlet pressure gauge 26 is provided on one side of the observation window 25. A status control box 27 is provided on one side of the inlet and outlet pressure gauge 26.

[0022] Specifically, in this structure, the water to be filtered first enters the 360-degree annular water distributor 4 inside the upper cover 3 through the water inlet pipe 5. The 360-degree annular water distributor 4 evenly distributes the water into the outer shell 2, avoiding local water flow concentration, so that the water can flow evenly through the packing filter bed 10 below, ensuring the consistency of the filtration effect. When the water flows through the packing filter bed 10 filled with multiple layers of active media, the multiple active media exert their respective characteristics to intercept and adsorb suspended solids, impurities and organic matter in the water, thereby achieving water purification and filtration.

[0023] Before or during filtration, the air inside the housing 2 is discharged through the exhaust pipe 6 connected to the 360-degree annular water distributor 4. The exhaust valve 23 can control the exhaust process to prevent air resistance from affecting the water flow filtration. The filtered water reaches the bottom of the housing 2 and is collected by the 360-degree annular water distributor collector 7. It then flows out through the water outlet pipe 8 and becomes the filtered usable water.

[0024] During equipment maintenance or repair, the vent valve 24 is opened to drain residual water and impurities from the outer casing 2 through the vent pipe 9, facilitating cleaning and inspection of the equipment's interior. The inlet and outlet pressure gauges 26 monitor the inlet and outlet water pressures in real time, using the pressure difference to determine the filter bed blockage and enable timely backwashing operations. The status control box 27 is used to control the equipment's operating status, such as start-up, stop, and backwashing operations. The observation window 25 can be used to observe the internal water flow and packing condition. The packing port 11 facilitates the addition or replacement of active media packing in the packing filter bed 10 to maintain the equipment's filtration performance.

[0025] In a specific embodiment, as shown in the appendix Figure 1 , 2 As shown, connecting plates 21 are fixedly installed on the upper surface of the outer shell 2 and the lower surface of the upper cover 3. Several bolts 22 are threaded on both connecting plates 21, and they can be detachably connected by the bolts 22.

[0026] Specifically, in this structure, the connecting plate 21 on the upper surface of the outer shell 2 and the lower surface of the upper cover 3 provides a connecting base plane. The bolts 22 are passed through the corresponding threaded holes on the two connecting plates 21 in sequence and tightened. The bolts 22 make the two connecting plates 21 fit tightly together, so that the upper cover 3 is firmly installed on the outer shell 2. When the equipment needs to be repaired or the active medium of the internal packing filter bed 10 needs to be replaced, the bolts 22 are unscrewed and the upper cover 3 is separated from the outer shell 2.

[0027] In a specific embodiment, as shown in the appendix Figure 1 , 3 As shown, the top of the upper cover 3 is provided with a lifting and moving structure, which includes an L-shaped bracket 12. The L-shaped bracket 12 is movably mounted on the top of the base plate 1 and located on one side of the outer shell 2. Two electric push rods 13 are provided on the top of the L-shaped bracket 12. The output ends of the two electric push rods 13 are fixedly connected to the upper cover 3. Two mounting grooves 14 are opened on the surface of the base plate 1. A lead screw 15 is rotatably mounted inside one mounting groove 14, and a slide rod 16 is fixedly mounted inside the other mounting groove 14. The lead screw 15 and the slide rod 16 are respectively provided with threads on their exteriors. Block 17 and slider 18 are provided, and a motor 19 is provided at one end of the lead screw 15. A movable seat 20 is provided on the surface of the base plate 1 and at the bottom of the L-shaped bracket 12. The motor 19 is fixedly installed at one end of the base plate 1, and the output end of the motor 19 is fixedly connected to the lead screw 15 inside one of the mounting slots 14. The threaded block 17 is located outside the lead screw 15 and is threadedly connected to the lead screw 15. The slider 18 is slidably connected to the slide rod 16. The threaded block 17 and slider 18 are both fixedly installed at the bottom of the movable seat 20, and the movable seat 20 is fixedly connected to the bottom of the L-shaped bracket 12.

[0028] Specifically, in this structure, to facilitate the replacement of the packing inside the packed filter bed 10, after removing the bolts 22 on the connecting plate 21 between the upper surface of the outer shell 2 and the lower surface of the upper cover 3, the electric push rod 13 drives the upper cover 3 to extend upward, separating the upper cover 3 from the outer shell 2. Then, the motor 19 drives the lead screw 15 to rotate, causing the threaded block 17 to move the L-shaped bracket 12 away from the outer shell 2 via the moving seat 20 through the slider 18 and the sliding rod 16 on the base plate 1.

[0029] The L-shaped bracket 12 drives the upper cover 3 to move away from the outer shell 2 after being lifted. At this time, the multi-layer active media packing in the packing filter bed 10 inside the outer shell 2 is exposed, which makes it convenient for operators to replace the packing and provides good operating space for replacing the packing.

[0030] Working principle of this utility model:

[0031] This application provides a multi-layer activated media fine filter. First, the water to be filtered enters the 360-degree annular water distributor 4 inside the upper cover 3 through the inlet pipe 5. The water distributor evenly disperses the water flow to the outer shell 2, so that the water flows evenly through the packing filter bed 10. When the water flows through the packing filter bed 10 filled with multi-layer activated media, the multi-layer activated media play a role in interception and adsorption, removing suspended solids, impurities and organic matter in the water, thereby achieving water purification and filtration. The purified water reaches the bottom of the outer shell 2, is collected by the 360-degree annular water collector 7, and then flows out through the outlet pipe 8 as usable water.

[0032] When the packing material in the packed filter bed 10 needs to be replaced, first remove the bolts 22 connecting the outer shell 2 and the upper cover 3. The electric push rod 13 drives the upper cover 3 to extend upward, separating the upper cover 3 from the outer shell 2. Then, the motor 19 drives the lead screw 15 to rotate. The threaded block 17 drives the L-shaped bracket through the moving seat 20, and slides on the slide rod 16 through the slider 18, so that the L-shaped bracket moves away from the outer shell 2 on the base plate 1. The L-shaped bracket drives the raised upper cover 3 to move synchronously, thereby exposing the multi-layer active media packing material in the packed filter bed 10 inside the outer shell 2, providing a good operating space for the operator to replace the packing material.

[0033] It should be noted that all contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used. Electrical control components not mentioned in this technical solution are existing technologies and are therefore not shown in the figures, and will not be described here.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
