Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a multi-media filtration device. Background Technology

[0002] In the context of comprehensive water resource utilization today, rainwater reuse is an important way to supplement water resources, and the development of efficient treatment devices is crucial. During the process of rainwater falling and being collected, it carries various suspended solids, which requires the use of multi-media filtration devices to intercept suspended solids of different particle sizes in the filter media layer to achieve effective removal of pollutants.

[0003] A Chinese patent with authorization announcement number CN214270419U discloses a multi-media rainwater filtration tank for sponge cities. The tank includes a tank body with several guide plates at the upper part of the interior. An inlet is located in the middle of the upper part of the tank body, connected to an inlet valve and a drain valve via a three-way pipe. An exhaust valve is also located at the upper part of the tank body. An outlet is located in the middle of the lower part of the tank body, connected to a backwash valve and a drain valve via a three-way pipe. A water collection filter cap is located at the lower part of the interior of the tank body, with a water collection area between the lower side of the filter cap and the tank body. An activated carbon layer is located on the upper side of the filter cap, followed by an anthracite layer, and then a quartz sand layer. An inlet is located at the upper edge of the tank body, and a outlet is located at the lower edge. This design enables multi-media filtration of rainwater and facilitates easy replacement of the filter media, ensuring effective filtration.

[0004] However, the above-mentioned device still has some problems. In practical applications, when the flocculated rainwater enters the recycled water tank, it will accumulate in a certain area of ​​the arc-shaped filter plate, causing the filter holes to become blocked, which prevents the rainwater from quickly entering the recycled water tank and reduces the efficiency of rainwater treatment. Therefore, a multi-media filtration device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a multi-media filtration device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A multi-media filtration device of this utility model includes a recycled water tank. An inlet is provided on the top side of the recycled water tank. Two support plates are respectively installed on both sides of the inlet on the top side of the recycled water tank. Each support plate has an arc-shaped groove inside. A sliding block is slidably installed inside the arc-shaped groove. A water inlet hopper is installed between the sliding blocks. An arc-shaped filter plate is installed inside the water inlet hopper. An arc-shaped worm gear is installed on one side of one of the sliding blocks. The arc of the arc-shaped worm gear is the same as that of the arc-shaped groove. Two mounting plates are symmetrically installed at the top edge of the recycled water tank. A servo motor is installed on one side of each mounting plate. A rotating shaft is installed at the output end of the servo motor. One end of the rotating shaft is rotatably installed inside the other mounting plate. A worm is fitted on the outside of the rotating shaft, and the worm meshes with the arc-shaped worm gear to realize the swinging of the water inlet hopper, allowing rainwater to be fully discharged into the recycled water tank, thus improving filtration efficiency.

[0007] Preferably, the top four corners of the recycled water tank are fixed with support columns, and a water storage tank is installed at the top of the support columns. The water storage tank has a processing chamber inside, and an inlet pipe is connected to the inside of the water storage tank and the processing chamber. An outlet pipe is connected to the bottom of the water storage tank, and an outlet valve is installed on the outlet pipe to facilitate the initial flocculation of rainwater.

[0008] Preferably, a stirring motor is installed on the top side of the water storage tank, a rotating shaft is installed at the output end of the stirring motor, a driving gear is installed at the top of the rotating shaft, a turntable is installed at the top of the rotating shaft, a connecting shaft is rotatably installed through the edge of the turntable, a driven gear is installed at the top of the connecting shaft, and the driving gear and the driven gear mesh with each other. Three sets of stirring blades, each consisting of three blades, are installed at equal intervals on the outer sides of both the rotating shaft and the connecting shaft. The stirring blades on the rotating shaft and the connecting shaft are staggered to accelerate the flocculation efficiency of rainwater, thereby improving the efficiency of rainwater filtration.

[0009] Preferably, the outlet pipe is located above the inlet hopper, and the movement range of the inlet hopper is still located above the outlet pipe, ensuring that the flocculated rainwater can accurately enter the recycled water tank.

[0010] Preferably, an anthracite packing layer is installed between the top two sides of the recycled water tank, a quartz sand packing layer is installed between the middle two sides of the recycled water tank, an activated carbon packing layer is installed between the bottom two sides of the recycled water tank, and a drain pipe is connected to one side of the bottom of the recycled water tank. A drain valve is installed inside the drain pipe to achieve multi-stage filtration and improve the filtration effect.

[0011] Preferably, water quality sensors are installed on the bottom inner walls of both the recycled water tank and the storage tank, an internal pressure monitoring sensor is installed on the bottom inner wall of the recycled water tank, an intelligent control system is installed on the outside of the recycled water tank, and a control panel is installed on one side of the recycled water tank. The control panel is used for signal transmission from the sensors and operation control of the intelligent control system and the electrical components inside the device, realizing an integrated design that facilitates maintenance and improves the automation level of the device.

[0012] The advantages of this utility model are:

[0013] 1. When the servo motor of this utility model starts, its output end drives the rotating shaft to rotate, and the worm gear mounted on the outside of the rotating shaft rotates accordingly. Because the worm gear meshes with the arc-shaped worm wheel, the arc-shaped worm wheel drives the sliding block to slide in the arc-shaped groove under the drive of the worm gear, thereby realizing the swing of the water inlet bucket. During the swing, the rainwater can be fully dispersed on the top of the recycled water tank, so that the rainwater can enter the recycled water tank through the filter holes on the arc-shaped filter plate, thereby improving the filtration efficiency.

[0014] 2. When the stirring motor of this utility model is started, its output end drives the rotating shaft to rotate. The rotating shaft drives the top drive gear to rotate on one hand, and drives the stirring blades to start stirring the mixture of rainwater and flocculant on the other hand. This causes the connecting shaft and stirring blades to rotate. Under the action of the turntable, the connecting shaft can revolve in the treatment chamber, which can stir the rainwater from different angles and positions, accelerate the uniformity of mixing of rainwater and flocculant and the speed of flocculation reaction, thereby improving flocculation efficiency.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1 , 2 As shown in Figures 3 and 5, a multi-media filtration device includes a reclaimed water tank 1. An inlet 2 is provided on the top side of the reclaimed water tank 1. Two support plates 3 are respectively installed on both sides of the inlet 2 on the top side of the reclaimed water tank 1. Each support plate 3 has an arc-shaped groove 4 inside. A sliding block 5 is slidably installed inside the arc-shaped groove 4. A water inlet hopper 6 is installed between the sliding blocks 5. An arc-shaped filter plate 7 is installed inside the water inlet hopper 6. An arc-shaped worm gear 8 is installed on one side of one of the sliding blocks 5. The arc of the arc-shaped worm gear 8 is the same as that of the arc-shaped groove 4. Two mounting plates 9 are symmetrically installed at the top edge of the reclaimed water tank 1. A servo motor 10 is installed on one side of the mounting plate 9. A rotating shaft 11 is installed at the output end of the servo motor 10. One end of the rotating shaft 11 is rotatably installed inside the other mounting plate 9. A worm gear 12 is fitted on the outside of the rotating shaft 11, and the worm gear 12 meshes with the arc-shaped worm gear 8.

[0024] The water outlet pipe 17 is located above the water inlet 6, and the movement range of the water inlet 6 is still located above the water outlet pipe 17;

[0025] A layer of anthracite packing material 26 is installed between the top two sides of the recycled water tank 1, a layer of quartz sand packing material 27 is installed between the middle two sides of the recycled water tank 1, a layer of activated carbon packing material 28 is installed between the bottom two sides of the recycled water tank 1, and a drain pipe 29 is connected to one side of the bottom of the recycled water tank 1. A drain valve 30 is installed inside the drain pipe 29.

[0026] Water quality sensors 31 are installed on the inner walls of the bottom ends of both the recycled water tank 1 and the storage tank 14. An internal pressure monitoring sensor 32 is installed on the inner wall of the bottom side of the recycled water tank 1. An intelligent control system 33 is installed on the outer side of the recycled water tank 1. A control panel 34 is installed on one side of the recycled water tank 1. The control panel 34 is used for signal transmission from the sensors and for operating and controlling the intelligent control system 33 and the electrical components inside the device. During operation, in practical applications, when the flocculated rainwater enters the recycled water tank 1, it accumulates in a certain area of ​​the arc-shaped filter plate 7, causing blockage of the filter holes. This prevents the rainwater from quickly entering the recycled water tank 1, reducing the efficiency of rainwater treatment. After the flocculation operation is completed, the outlet valve 18 on the outlet pipe 17 is opened, and the flocculated rainwater flows through the outlet pipe 17. When the water flows into the inlet hopper 6, the servo motor 10 starts, and its output drives the rotating shaft 11 to rotate. The worm gear 12 mounted on the outside of the rotating shaft 11 rotates accordingly. Because the worm gear 12 meshes with the arc-shaped worm wheel 8, the arc-shaped worm wheel 8 drives the sliding block 5 to slide in the arc-shaped groove 4 under the drive of the worm gear 12, thereby realizing the swing of the inlet hopper 6. During the swing, the rainwater can be fully dispersed at the top of the recycled water tank 1, so that the rainwater can enter the recycled water tank 1 through the filter holes on the arc-shaped filter plate 7, thereby improving the filtration efficiency. The arc-shaped filter plate 7 will filter out larger impurities and other large particles after flocculation, preventing large particles from directly entering the interior of the recycled water tank 1 and causing blockage or damage to the subsequent packing layer. The rainwater is initially purified to ensure that the impurities in the rainwater entering the recycled water tank 1 are small in size and relatively uniformly distributed.

[0027] After initial filtration by the arc-shaped filter plate 7, the rainwater enters the reclaimed water tank 1. The anthracite particles are relatively large and have a rough surface, which can intercept relatively large suspended solids in the rainwater. Simultaneously, its rough surface can adsorb some organic matter and colloidal substances. Next, the rainwater continues to flow downwards. Quartz sand, with its high hardness and good chemical stability, and smaller particle size than anthracite, can intercept even smaller suspended solids remaining after passing through the anthracite layer, further reducing the turbidity of the rainwater. Finally, activated carbon, with its highly developed pore structure and huge specific surface area, can deeply adsorb organic matter and other substances in the rainwater. After multi-stage filtration through these three layers of filler, a large amount of pollutants such as suspended solids, organic matter, and odors in the rainwater are removed, and the water quality is significantly improved. The clean rainwater after multi-media filtration is discharged through the drain pipe 29 on one side of the bottom of the recycled water tank 1. When drainage is needed, the drain valve 30 inside the drain pipe 29 is opened, and the rainwater flows out of the recycled water tank 1 under the action of gravity for effective utilization, reducing the waste of water resources. It should be noted that the inner walls of the recycled water tank 1 and the water storage tank 14 are lined with sound-absorbing cotton with noise-reducing material, which effectively reduces the noise during equipment operation.

[0028] In actual operation, the water quality sensor 31 monitors the water quality of the water storage tank 14 and the recycled water tank 1 in real time. The intelligent control system 33 adjusts the dosage ratio of the reagent accordingly and controls the frequency conversion operation of the equipment. The internal pressure monitoring sensor 32 monitors the internal pressure of the multi-media filter in real time. When the pressure is abnormal, the intelligent control system 33 starts the automatic maintenance program to ensure the normal operation of the filter. The operator can monitor and control the overall operation of the device through the control panel 34. The specific model of the water quality sensor 31 is HACH-LDO101, the specific model of the internal pressure monitoring sensor 32 is MPX5010DP, and the specific model of the intelligent control system 33 is Siemens S7-1200 series PLC.

[0029] Please see Figure 1 , 2 As shown in Figure 4, support columns 13 are fixedly connected to the four corners of the top side of the recycled water tank 1. A water storage tank 14 is installed at the top of the support columns 13. A processing chamber 15 is opened inside the water storage tank 14. An inlet pipe 16 is connected to the inside of the processing chamber 15. An outlet pipe 17 is connected to the bottom side of the water storage tank 14. An outlet valve 18 is installed on the outlet pipe 17.

[0030] A stirring motor 19 is installed on the top side of the water storage tank 14. A rotating shaft 20 is installed at the output end of the stirring motor 19. A drive gear 21 is installed at the top of the rotating shaft 20. A turntable 22 is installed at the top of the rotating shaft 20. A connecting shaft 23 is rotatably installed through the edge of the turntable 22. A driven gear 24 is installed at the top of the connecting shaft 23, and the drive gear 21 and the driven gear 24 mesh with each other. Three sets of stirring blades 25 are equidistantly installed on the outer sides of both the rotating shaft 20 and the connecting shaft 23, with the stirring blades 25 on the rotating shaft 20 and the connecting shaft 23 being staggered. During operation, in the process of rainwater treatment, rainwater contains various suspended solids, and it is necessary to intercept suspended solids of different particle sizes in the filter layer to effectively... To remove various pollutants and improve the filtration effect of rainwater, rainwater treatment flocculant and rainwater are added into the treatment chamber 15 through the inlet pipe 16 in a certain proportion. The stirring motor 19 is started, and its output end drives the rotating shaft 20 to rotate. The rotating shaft 20 drives the top drive gear 21 to rotate and drives the stirring blades 25 to start stirring the mixture of rainwater and flocculant. The drive gear 21 and the driven gear 24 mesh with each other, causing the connecting shaft 23 and the stirring blades 25 to rotate. Under the action of the turntable 22, the connecting shaft 23 can revolve in the treatment chamber 15, which can stir the rainwater from different angles and positions, accelerate the uniformity of the mixing of rainwater and flocculant and the speed of the flocculation reaction, thereby improving the flocculation efficiency.

[0031] Working principle: First, rainwater treatment flocculant and rainwater are introduced into the treatment chamber 15 through the inlet pipe 16. The stirring motor 19 is started, and its output end drives the rotating shaft 20 to rotate. The rotating shaft 20 drives the top drive gear 21 to rotate and the stirring blades 25 to start stirring the mixture of rainwater and flocculant. The drive gear 21 and the driven gear 24 mesh with each other, causing the connecting shaft 23 and the stirring blades 25 to rotate. Under the action of the turntable 22, the connecting shaft 23 can revolve in the treatment chamber 15, which can stir the rainwater from different angles and positions, accelerate the uniformity of the mixing of rainwater and flocculant and the speed of flocculation reaction, thereby improving flocculation efficiency.

[0032] After the flocculation operation is completed, the outlet valve 18 on the outlet pipe 17 is opened, and the flocculated rainwater flows into the inlet hopper 6 through the outlet pipe 17. The servo motor 10 is started, and its output end drives the rotating shaft 11 to rotate. The worm gear 12 mounted on the outside of the rotating shaft 11 rotates accordingly. Because the worm gear 12 meshes with the arc-shaped worm wheel 8, the arc-shaped worm wheel 8 drives the sliding block 5 to slide in the arc-shaped groove 4 under the drive of the worm gear 12, thereby realizing the swing of the inlet hopper 6. During the swing, the rainwater can be fully dispersed at the top of the recycled water tank 1, so that the rainwater can enter the recycled water tank 1 through the filter holes on the arc-shaped filter plate 7, improving the filtration efficiency. The arc-shaped filter plate 7 will filter out larger impurities and other large particles after flocculation, preventing large particles from directly entering the interior of the recycled water tank 1 and causing blockage or damage to the subsequent packing layer. The rainwater is initially purified to ensure that the impurities in the rainwater entering the recycled water tank 1 are small in size and relatively uniformly distributed.

[0033] After initial filtration by the arc-shaped filter plate 7, the rainwater enters the reclaimed water tank 1. The anthracite particles are relatively large and have a rough surface, which can intercept relatively large suspended solids in the rainwater. Simultaneously, its rough surface can adsorb some organic matter and colloidal substances. Next, the rainwater continues to flow downwards. Quartz sand, with its high hardness and good chemical stability, and smaller particle size than anthracite, can intercept even smaller suspended solids remaining after passing through the anthracite layer, further reducing the turbidity of the rainwater. Finally, activated carbon, with its highly developed pore structure and huge specific surface area, can deeply adsorb organic matter and other substances in the rainwater. After multi-stage filtration through these three layers of filler, a large amount of pollutants such as suspended solids, organic matter, and odors in the rainwater are removed, and the water quality is significantly improved. The clean rainwater after multi-media filtration is discharged through the drain pipe 29 on one side of the bottom of the recycled water tank 1. When drainage is needed, the drain valve 30 inside the drain pipe 29 is opened, and the rainwater flows out of the recycled water tank 1 under the action of gravity for effective utilization, reducing the waste of water resources. It should be noted that the inner walls of the recycled water tank 1 and the water storage tank 14 are lined with sound-absorbing cotton with noise-reducing material, which effectively reduces the noise during equipment operation.

[0034] In actual operation, the water quality sensor 31 monitors the water quality of the water storage tank 14 and the recycled water tank 1 in real time. The intelligent control system 33 adjusts the dosage ratio of the reagent accordingly and controls the frequency conversion operation of the equipment. The internal pressure monitoring sensor 32 monitors the internal pressure of the multi-media filter in real time. When the pressure is abnormal, the intelligent control system 33 starts the automatic maintenance program to ensure the normal operation of the filter. The operator can monitor and control the overall operation of the device through the control panel 34.
