Description

Technical Field

[0001] This utility model belongs to the field of water treatment engineering technology, specifically a filtration device for industrial circulating water treatment. Background Technology

[0002] Sand filters are a type of mechanical filtration equipment commonly used in industrial water treatment. They mainly remove suspended solids, colloids and other impurities from water through the interception and adsorption of granular filter media.

[0003] During use, the water to be treated flows in from the top of the sand filter and passes through the filter media layer from top to bottom. Suspended solids, colloids and other impurities in the water are adsorbed by the surface of the filter media particles or mechanically intercepted, and the purified water is discharged from the bottom.

[0004] Traditional sand filters often adopt an integrated structure. When a sand filter unit becomes clogged or damaged, the entire equipment must be shut down for maintenance. This requires closing the inlet valve, emptying the filter tank, and even disassembling a large number of pipes and accessories. The entire shutdown and maintenance cycle may last for several hours to several days, which seriously affects the continuous operation of the water treatment system. Therefore, a filtration device for industrial circulating water treatment is proposed to address the above problems. Utility Model Content

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a filtration device for industrial circulating water treatment. Through the setting of a middle layer filter media chamber and a water connection box, and through the setting of multiple layers of detachable and replaceable modular individual filter sand chambers, multi-stage filtration can be performed. At the same time, the individual filter sand chambers can be disassembled and replaced independently without stopping the entire sand filter for maintenance, which greatly improves maintenance efficiency.

[0026] 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 scope of protection of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides a filtration device for industrial circulating water treatment, including a tank 1; characterized in that: the top of the tank 1 is symmetrically provided with water inlets 11; the bottom of the tank 1 is provided with water outlets 12; a tank door 13 is hinged to the front of the tank 1; multiple sets of water-passing plates 14 are fixedly connected to the inner side wall of the tank 1; the tank 1 is provided with an upper filter media bin 15, a middle filter media bin 16, a lower filter media bin 17 and a water connection box 18; the upper filter media bin 15 is located on top of the water-passing plate 14 and is slidably connected to the water-passing plate 14; the middle filter media bin 16 and the lower filter media bin 17 are provided with water-passing plates 14; the upper filter media bin 15 is located on top of the water-passing plate 14 and is slidably connected to the water-passing plate 14; the middle filter media bin 16 and the lower filter media bin 17 are slidably connected to the water-passing plate 17 ... The filter media chamber 17 is located at the bottom of the water-passing plate 14 and is connected to the water-passing plate 14 via a dovetail groove mechanism; the upper filter media chamber 15 is symmetrically fixed to the inner side wall of the upper isolation plate 19; the middle filter media chamber 16 and the lower filter media chamber 17 are fixed to the inner side walls of the middle and lower isolation plates 101; the water connection box 18 is located between the middle filter media chamber 16 and the water-passing plate 14 and is fixedly connected to the water-passing plate 14; the upper filter media chamber 15 is filled with quartz sand; the middle filter media chamber 16 is filled with activated carbon; the lower filter media chamber 17 is filled with manganese sand; firstly, the upper isolation plate 19 and the middle and lower isolation plates 101 are connected to the inner side wall of the filter media chamber 15. The separator 101 isolates the corresponding filter media to prevent outflow. Water is introduced into the tank 1 through the inlet 11. The water inside the tank 1 falls onto the quartz sand in the upper filter media bin 15 for filtration, then flows out through the upper separator 19 and enters the middle filter media bin 16 through the opening of the water-passing plate 14, where it is filtered by activated carbon. Next, the water flows through the lower separator 101 into the connecting box 18, and then through the water-passing plate 14 at the bottom of the connecting box 18 into the lower filter media bin 17 for manganese sand filtration, before finally passing through the lower separator 101 again. The filter media flows out, achieving multi-stage filtration. When the corresponding filter media in the upper filter media chamber 15, middle filter media chamber 16, and lower filter media chamber 17 become clogged or reach the end of their service life, the tank door 13 is opened. The corresponding upper filter media chamber 15, middle filter media chamber 16, or lower filter media chamber 17 can be removed through the dovetail groove mechanism, and the internal filter media can be rinsed or replaced, achieving quick disassembly and replacement. Through the multi-layered, detachable, and replaceable modular individual filter media chambers, multi-stage filtration can be performed. At the same time, each individual filter media chamber can be disassembled and replaced independently without stopping the entire sand filter for maintenance, greatly improving maintenance efficiency.

[0029] Furthermore, such as Figure 5 , Figure 6As shown, a motor 2 is fixedly connected to one end of the tank body 1; an output rod 21 is provided at the output end of the motor 2; the output rod 21 is rotatably connected through the inner wall of the tank body 1; a hollow disc 22 is slidably connected to the surface of the output rod 21; a fixing ring 23 is fixedly connected to the inner wall of the hollow disc 22; a fitting ring 24 is rotatably connected to the side wall of the fixing ring 23; a flow guide 25 is fixedly connected to the side wall of the fitting ring 24; an elastic reciprocating mechanism is provided on the side wall of the output rod 21; when water enters the tank body 1 from the inlet 11, most of the water flows onto the flow guide 25, expanding the downstream flow range of the water through the path of the side wall of the flow guide 25, and then the motor 2 is started to output through the output rod 21. The hollow disc 22 rotates, and at this time, the hollow disc 22 slides downward under the axial driving force of the rotation. At the same time, the elastic reciprocating mechanism restricts the sliding distance of the hollow disc 22, and through the rebound force, the hollow disc 22 slides up and down reciprocally, thereby driving the guide shroud 25 to reciprocate up and down, and reciprocatingly adjusting the height of the expanded water flow range, thereby improving the uniformity of the water flow falling on the surface of the filter media in the upper filter media bin 15. By expanding and adjusting the falling path of the water flow, the water flow can fall in a circumferential range, thereby making the water flow evenly distributed on the surface of the upper filter media, avoiding local water flow concentration and excessively fast downward flow, which would lead to insufficient filtration and improve the overall filtration efficiency.

[0030] Furthermore, such as Figure 6 As shown, the elastic reciprocating mechanism includes a fixed disk 3 fixedly connected to the side wall of the output rod 21; a spring assembly 31 fixedly connected to the end of the fixed disk 3; the spring assembly 31 is fixedly connected to the hollow disk 22; when the hollow disk 22 slides down, the spring assembly 31 is compressed, and then the spring assembly 31 generates a rebound force that is transmitted to the hollow disk 22, giving the hollow disk 22 an upward thrust, thereby realizing the reciprocating sliding of the hollow disk 22 through the spring assembly 31, and adjusting the height of the extended water flow by reciprocating, thereby improving the uniformity of the water flow falling on the surface of the upper filter media.

[0031] Furthermore, such as Figure 6 As shown, multiple sets of positioning blocks 4 are fixedly connected to the end of the fixed disk 3; a spring rod 41 is fixedly connected to the inner wall of the positioning block 4; the spring rod 41 is fixedly connected to the guide shroud 25; during the reciprocating motion of the guide shroud 25, the elastic extension and contraction effect of the spring rod 41 causes the guide shroud 25 to slide down, causing the radius of the guide shroud 25 to shrink, thus tightening the water flow range. When the guide shroud 25 slides up, the spring rod 41 pushes the inner wall of the guide shroud 25 through the rebound force generated during contraction, causing it to expand the radius of the circle, thereby increasing the water flow expansion range. By adjusting the radius of the circle, the circumferential range of the water flow can be adaptively adjusted, thereby improving the uniformity of the water flow and improving the overall filtration effect.

[0032] Furthermore, such as Figure 3 , Figure 4As shown, the dovetail groove mechanism includes a dovetail slide groove 5 at the bottom of the water-passing plate 14; dovetail blocks 51 at the top of the middle layer filter media bin 16 and the lower layer filter media bin 17; and dovetail blocks 51 slidably connected to the inner side wall of the dovetail slide groove 5. The dovetail groove structure composed of the dovetail slide groove 5 and the dovetail blocks 51 achieves a stable removal and repositioning effect for the middle layer filter media bin 16 and the lower layer filter media bin 17, which facilitates the replacement of filter media inside the middle layer filter media bin 16 and the lower layer filter media bin 17 and improves maintenance efficiency.

[0033] Furthermore, such as Figure 5 As shown, a guide pipe 6 is fixed to the inner wall of the tank 1; the guide pipe 6 is correspondingly set with the water inlet 11; when water is introduced into the tank 1 through the water inlet 11, it is guided to the flow guide shroud 25 through the guide pipe 6, thereby improving the diffusion and diversion effect of the flow guide shroud 25 and the uniformity of water flow distribution.

[0034] Furthermore, such as Figure 4 As shown, handles 7 are provided at the bottom of the upper filter media bin 15, the middle filter media bin 16 and the lower filter media bin 17; when moving the upper filter media bin 15, the middle filter media bin 16 and the lower filter media bin 17 to the outside for filter media replacement, the handles 7 are used for support and movement control, improving the operational flexibility when moving and resetting.

[0035] Working principle: First, the upper isolation plate 19 and the middle and lower isolation plates 101 isolate the corresponding filter media to prevent outflow. Water is introduced into the tank 1 through the inlet 11. The water entering the tank 1 falls onto the quartz sand in the upper filter media bin 15 for filtration. Then, it flows out through the upper isolation plate 19 and enters the middle filter media bin 16 through the opening of the water-passing plate 14, where it is filtered by activated carbon. Next, the water flows through the middle and lower isolation plates 101 into the connecting water box 18, and then through the water-passing plate 14 at the bottom of the connecting water box 18 into the lower filter media bin 17 for manganese sand filtration. Finally, it flows out through the middle and lower isolation plates 101, achieving a multi-stage filtration effect. When the upper filter media bin 15, the middle filter media bin 16, and the lower filter media bin 17 are connected, the water is filtered through the manganese sand. When the filter sand in the filter media bin 17 becomes clogged or reaches the end of its service life, the tank door 13 is opened. The corresponding upper filter media bin 15, middle filter media bin 16, or lower filter media bin 17 can be removed via the dovetail groove mechanism. The internal filter media can then be rinsed or replaced, enabling quick disassembly and replacement. When water enters the tank 1 through the inlet 11, most of the water flows onto the guide shroud 25, expanding the downward flow range through the path on the side wall of the guide shroud 25. Then, the motor 2 is started, driving the hollow disc 22 to rotate via the output rod 21. At this time, the hollow disc 22 slides downward under the axial driving force of rotation. Simultaneously, the elastic reciprocating mechanism limits the sliding distance of the hollow disc 22 and, through the rebound force, causes the hollow disc 22 to slide up and down reciprocally, thereby driving the guide shroud 25. 5. The reciprocating motion of the hollow disc 22 adjusts the height of the expanded water flow, thereby improving the uniformity of the water flow falling on the surface of the filter media in the upper filter media bin 15. When the hollow disc 22 slides down, it compresses the spring assembly 31, and then the spring assembly 31 generates a rebound force that is transmitted to the hollow disc 22, giving the hollow disc 22 an upward thrust. Thus, the reciprocating sliding of the hollow disc 22 through the spring assembly 31 adjusts the height of the expanded water flow. During the reciprocating motion of the guide hood 25, the elastic extension and contraction effect of the spring rod 41 causes the spring rod 41 to contract and reduce the radius of the guide hood 25 when it slides down, thereby tightening the water flow range. When the guide hood 25 slides up, the spring rod 41 generates a force that, when it contracts, causes the water flow range to tighten. The rebound force pushes the inner wall of the guide hood 25, expanding its radius and thus increasing the water flow range. By adjusting the radius, the circumferential range of the water flow can be adaptively adjusted. The dovetail groove structure composed of the dovetail slide 5 and the dovetail block 51 achieves the stable removal and repositioning effect of the middle filter media bin 16 and the lower filter media bin 17, facilitating the replacement of the filter media inside the middle filter media bin 16 and the lower filter media bin 17. When water is introduced into the tank 1 through the inlet 11, it is guided to the guide hood 25 through the guide pipe 6, thereby improving the diffusion and diversion effect of the guide hood 25. When moving the upper filter media bin 15, the middle filter media bin 16, and the lower filter media bin 17 to the outside for filter media replacement, the handle 7 is used for support and movement control.
