Description

Technical Field

[0001] This utility model relates to a backwash water recovery device, specifically a filter backwash water recovery device, belonging to the field of filter technology. Background Technology

[0002] In recent years, with the continuous expansion of chemical enterprises, the consumption of resources and energy in the production process has increased significantly. Water consumption has become an important economic and technical indicator for the rapid development of chemical enterprises. Water conservation, energy saving, the development of a circular economy, and the improvement of water resource reuse rates are urgent matters for chemical enterprises and an essential path to enhance their competitiveness and achieve sustainable development. According to the requirements of various production processes, water treatment equipment such as filters are often installed in the clean or turbid circulating water system to ensure the cooling effect and water quality of the circulating water during normal operation. However, the backwashing of the water treatment system generates a large amount of wastewater, and the discharge volume is substantial, which can even lead to serious environmental pollution problems. This is incompatible with the enterprise's energy conservation and energy saving efforts. Therefore, considering wastewater recycling to promote the simultaneous development of economic and environmental benefits is imperative.

[0003] A search revealed a Chinese patent with publication number CN216653592U, which discloses an energy-saving and loss-reducing filter backwash water recovery device. The device includes a filter, a recovery tank, and a dust removal tank. A T-shaped backwash water pipe is fixedly installed at the rear end of the filter and connects to both the recovery tank and the dust removal tank. A water outlet pipe is fixedly installed at the rear end of the recovery tank and connects to the dust removal tank. The recovery tank has symmetrically arranged movable grooves on both sides inside. A guide rod is welded and fixed to the bottom of each movable groove, and an insertion hole is provided at the top of each groove. The insertion hole extends through to the upper surface of the recovery tank, and an air outlet sealing device is inserted into the insertion hole. An installation hole is provided between the movable grooves on one side wall of the recovery tank, and a filter cloth cleaning device is inserted into the installation hole. A filter cloth support device is welded into the recovery tank.

[0004] While the aforementioned devices can treat backwash water and then supply it to the circulating water system through a reflective water recovery device, thus saving water resources and meeting energy conservation and emission reduction requirements, and the dust removal tank and recovery tank are connected so that they can serve as backups for each other, and a disc-shaped steel pipe connected to a compressed air pipe is installed at the bottom of the recovery tank to facilitate the cleaning of the filter cloth in the recovery tank and ensure the normal operation of the recovery device, the waste after cleaning the filter cloth still remains on top of the filter cloth, requiring manual cleaning, which is time-consuming, labor-intensive, and increases labor costs. Therefore, we provide a filter backwash water recovery device to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This filter backwash water recovery device filters backwash water through a filter plate and filter cloth.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The system includes a filter 1, which is connected to a backwash water pipe 2. The backwash water pipe 2 is equipped with a filtration mechanism 3. The filtration mechanism 3 includes a filter box 301, which has a filter chamber 302. The filter chamber 302 has two symmetrical sliding grooves 303, and each sliding groove 303 is slidably connected to a sliding rod 304. The sliding rod 304 is fixedly connected to a filter plate 305, and the filter plate 305 is fixedly connected to a filter cloth 306. The sliding rod 304 is slidably connected to a support plate 307, and the support plate 307 is fixedly mounted with a first servo motor 308. The output end of the first servo motor 308 is fixedly connected to a threaded rod 309. 309 is fixedly connected to a limiting block 310, a sliding rod 304 is fixedly connected to a connecting rod 311, the connecting rod 311 has a threaded hole 312, a support plate 307 is fixedly connected to a first connecting plate 313, an electronic telescopic rod 314 is fixedly installed on the first connecting plate 313, a cleaning brush 315 is fixedly installed at the output end of the electronic telescopic rod 314, a support plate 307 is fixedly connected to multiple first support columns 316, a filter box 301 is connected to a backwash water pipe 2, a filter plate 305 is slidably connected to a filter chamber 302, the threaded hole 312 is threadedly connected to a threaded rod 309, and multiple first support columns 316 are all fixedly connected to the filter box 301.

[0023] The first servo motor 308 and electronic telescopic rod 314 in this application are common electrical devices in the prior art, and their models or internal structures will not be described in detail here. They can also be replaced by other power sources. The connection between the backwash water pipe 2 and the filter box 301 is above the working position of the filter plate 305 and the filter cloth 306, and the connection between the filter box 301 and the first water supply pipe 4 is below the working position of the filter plate 305 and the filter cloth 306. The cleaning brush 315 is prior art and will not be described in detail. The backwash water can be filtered through the filter plate 305 and the filter cloth 306. When cleaning the filter debris, the first servo motor 308 is controlled. The rotation of the screw rod 309 causes the screw hole 312 to move upward, which in turn moves the sliding rod 304 upward. Simultaneously, the filter plate 305 slides upward inside the filter chamber 302. When the upper surface of the filter cloth 306 is parallel to the upper surface of the filter box 301, the first servo motor 308 is stopped, so that the upper surface of the filter cloth 306 and the upper surface of the filter box 301 are at the same height. Then, the electronic telescopic rod 314 is controlled to extend and retract, which in turn moves the cleaning brush 315 left and right, so that the cleaning brush 315 sweeps away the debris on the filter cloth 306, thus achieving the purpose of the device to quickly filter backwash water and remove debris.

[0024] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 The filter box 301 is connected to a first water supply pipe 4. The first water supply pipe 4 is equipped with a sedimentation mechanism 5. The sedimentation mechanism 5 includes a sedimentation frame 501, which is connected to the first water supply pipe 4. The sedimentation frame 501 has a sedimentation chamber 502. The sedimentation frame 501 is fixedly connected to a plurality of second support columns 503. The plurality of second support columns 503 are fixedly connected to a second connecting plate 504. The second connecting plate 504 is fixedly mounted with a second servo motor 505. The output end of the second servo motor 505 is fixedly connected to a first rotating rod 506. The first rotating rod 506 is fixedly connected to a plurality of stirring rods 507. The sedimentation frame 501 is connected to a second water supply pipe 7, which is connected to the filter 1.

[0025] The second water supply pipe 7 is equipped with a water pump and an electronic control valve. After the backwash water is settled in the sedimentation mechanism 5, the electronic control valve is opened, and then the water pump is turned on to pump the settled backwash water into the filter 1. The second servo motor 505 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources. By adding flocculant into the sedimentation chamber 502, and then controlling the second servo motor 505 to rotate, the first rotating rod 506 and the stirring rod 507 are driven to rotate. This allows the backwash water and flocculant in the sedimentation chamber 502 to be fully mixed. Then the second servo motor 505 is turned off, so that the first rotating rod 506 and the stirring rod 507 stop rotating. After the liquid mixed with the backwash water and flocculant is left to stand for a period of time, the fine garbage and fine suspended matter carried by the backwash water can be settled to the bottom of the sedimentation chamber 502, thus achieving the purpose of this device to quickly settle fine garbage and suspended matter.

[0026] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 The sedimentation mechanism 5 is equipped with a sewage discharge mechanism 6, which includes a sewage collection tank 601. The sewage collection tank 601 is connected to the sedimentation frame 501. The sewage collection tank 601 is connected to a sewage discharge frame 602. The sewage discharge frame 602 has a sewage discharge chamber 603. The sewage discharge chamber 603 has a through hole 604. A third servo motor 605 is fixedly installed in the sewage collection tank 601. The output end of the third servo motor 605 is fixedly connected to a second rotating rod 606. The second rotating rod 606 passes through the through hole 604 and is rotatably connected to the sewage discharge chamber 603. Multiple rotating plates 607 are fixedly connected to the second rotating rod 606. All of the multiple rotating plates 607 are rotatably connected to the sewage discharge chamber 603.

[0027] The third servo motor 605 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources. By starting the third servo motor 605, the second rotating rod 606 is driven to rotate, and the rotating plate 607 is driven to rotate, so that the garbage deposited at the bottom of the sedimentation chamber 502 can be discharged from the device. When the garbage deposited at the bottom of the sedimentation chamber 502 is discharged, the third servo motor 605 is turned off, so that the second rotating rod 606 and the rotating plate 607 stop rotating, thus achieving the purpose of the device to quickly clean the sedimented garbage.

[0028] In use, this invention delivers backwash water to the filtration mechanism 3 via the backwash water pipe 2. The backwash water is filtered through the filter plate 305 and filter cloth 306. When cleaning filter debris, the first servo motor 308 is controlled to rotate, which in turn drives the threaded rod 309 to rotate, causing the threaded hole 312 to move upwards. Simultaneously, the sliding rod 304 moves upwards, causing the filter plate 305 to slide upwards inside the filter chamber 302. When the upper surface of the filter cloth 306 is parallel to the upper surface of the filter box 301, the first servo motor 308 is controlled to rotate. The machine 308 stops rotating, so that the upper surface of the filter cloth 306 is at the same height as the upper surface of the filter box 301. Then, the electronic telescopic rod 314 is controlled to extend and retract, thereby driving the cleaning brush 315 to move left and right, so that the cleaning brush 315 sweeps away the debris on the filter cloth 306, achieving the purpose of this device to quickly filter backwash water and remove debris. The backwash water is transported to the sedimentation mechanism 5 through the first water supply pipe 4. Flocculant is added into the sedimentation chamber 502, and then the second servo motor 505 is controlled to rotate. The first rotating rod 506 rotates, simultaneously rotating the stirring rod 507, thus fully mixing the backwash water and flocculant inside the sedimentation chamber 502. Then, the second servo motor 505 is turned off, stopping the rotation of the first rotating rod 506 and the stirring rod 507. The mixture of backwash water and flocculant is allowed to stand for a period of time, allowing the fine debris and suspended solids carried by the backwash water to settle to the bottom of the sedimentation chamber 502, achieving the purpose of rapid sedimentation of fine debris and suspended solids. After the backwash water has settled in the sedimentation mechanism 5, the electronic control valve is opened, and then the water pump is turned on to pump the settled backwash water into the filter 1. The third servo motor 605 is then activated, driving the second rotating rod 606 to rotate, simultaneously rotating the rotating plate 607, thus discharging the debris deposited at the bottom of the sedimentation chamber 502. Once the debris has been completely discharged from the bottom of the sedimentation chamber 502, the third servo motor 605 is turned off, stopping the rotation of the second rotating rod 606 and the rotating plate 607, achieving the purpose of rapid cleaning of the settled debris.
