Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and more specifically, to a step-by-step filtration device for industrial circulating water treatment. Background Technology

[0002] Industrial circulating water systems are widely used in many industrial fields such as power, chemical, metallurgy, and pharmaceutical. Their core function is to achieve heat exchange, equipment cooling, or process media transfer through the circulation of water, making them a key infrastructure for ensuring the continuous and stable operation of industrial production. With the expansion of industrial production scale and the increase in process complexity, the water quality requirements for circulating water are becoming increasingly stringent. If pollutants such as suspended particulate matter, colloidal impurities, microbial slime, and rust residue in the water are not effectively removed, they can lead to blockage of heat exchanger pipes, reduced heat transfer efficiency, and accelerated equipment corrosion. This not only increases energy consumption and operating costs but may also cause unplanned shutdowns, resulting in serious economic losses. Currently, most filtration devices in industrial circulating water treatment employ a single filtration stage or a fixed filtration precision design, making it impossible to adapt to the dynamic changes in the particle size distribution of impurities in the industrial circulating water. In practical applications, the particle size range of impurities in circulating water is quite large, and a single filtration stage is prone to contradictions such as "insufficient filtration precision leading to impurity residue" or "excessive filtration precision leading to device clogging and increased energy consumption."

[0013] As attached Figure 1 To be continued Figure 5 As shown, an embodiment of the present invention provides a step-by-step filtration device for industrial circulating water treatment, including a support frame 1 and multiple filter components 2. The top of the support frame 1 is fixedly connected to the multiple filter components 2, the multiple filter components 2 are connected end to end, and the height of the multiple filter components 2 gradually decreases from the right to the left. like Figure 4As shown, the filter assembly 2 includes a fixed water pipe 21. One end of the fixed water pipe 21 is fixedly connected to a cleaning motor 24. The output end of the cleaning motor 24 is fixedly connected to a rotating disk 25. Both ends of the rotating disk 25 are fixedly connected to cleaning brushes 26. The rotating disk 25 is rotatably installed inside the fixed water pipe 21. A sinkhole 23 is provided at the bottom of the fixed water pipe 21. A sewage hopper 22 is fixedly connected to the bottom of the fixed water pipe 21. The fixed water pipe 21 is connected to the sewage hopper 22 through the sinkhole 23. The other end of the fixed water pipe 21 is fixedly connected to a threaded interface 29. A filter screen frame 27 is threaded on the outer surface of the threaded interface 29.

[0014] like Figure 5 As shown, the filter frame 27 includes a fixing cover 271, a filter cylinder 274, and a water spray pipe 2711. The fixing cover 271 has an internal threaded opening 272 on its left side, which is threaded onto the outer surface of the threaded interface 29. A fixing head 273 is fixedly fitted inside the fixing cover 271, and the side of the fixing head 273 is fixedly connected to the filter cylinder 274. A limiting groove 275 is formed inside the fixing cover 271, and a connecting water pipe 276 is fixedly connected to the bottom of the fixing cover 271. A connecting block 278 is fixedly connected to the right end of the fixed cover 271. An indicator light 2710 is fixedly connected to the side of the connecting block 278. A pulse switch valve 279 is fixedly connected to the bottom of the connecting block 278. A water spray pipe 2711 is rotatably installed on the side of the connecting block 278. A rotating ring 2712 is fixedly sleeved on the outer surface of the right end of the water spray pipe 2711. The rotating ring 2712 is rotatably installed inside the limiting groove 275. The water spray pipe 2711 is rotatably installed inside the filter screen cylinder 274.

[0015] Specifically, the cleaning motor 24 controls the rotating disk 25 to rotate at one end inside the fixed water pipe 21, causing the cleaning brush 26 to rotate inside the fixed water pipe 21, thereby cleaning the filter screen cylinder 274.

[0016] The inner wall of the rotating disk 25 is fixedly connected to a first magnet strip 28, the left end of the spray pipe 2711 is fixedly connected to a second magnet strip 2713, the second magnet strip 2713 is rotatably installed on the left wall of the filter cylinder 274, the second magnet strip 2713 is magnetically connected to the first magnet strip 28, the cleaning brush 26 is rotatably installed on the outer surface of the filter cylinder 274, and a water flow rate sensor 277 is provided at the lower end of the inside of the fixed cover 271, the water flow rate sensor 277 is located above the connecting water pipe 276.

[0017] Specifically, by setting up the spray pipe 2711 and the pulse switch valve 279, the water inside the water tank 16 is sprayed out from the spray pipe 2711 through the return water pipe 18 and the connecting block 278 via the action of the pulse switch valve 279. During the process of the cleaning motor 24 controlling the rotating disk 25 to rotate, the first magnet strip 28 rotates. Through the magnetic attraction of the first magnet strip 28 to the second magnet strip 2713, the spray pipe 2711 rotates inside the filter screen cylinder 274. At this time, the water inside the water tank 16 backwashes the filter screen cylinder 274 through the spray pipe 2711, washing away the mud and sand on the surface of the filter screen cylinder 274. The mud and sand are subjected to gravity and sink into the interior of the sewage hopper 22, and flow into the interior of the sewage pipe 13 through the connecting pipe 3.

[0018] In addition, the flow rate sensor 277 detects the flow rate of the connected water pipe 276, thereby determining the blockage status of the filter cylinder 274. The cleaning brush 26 is controlled by an electrical signal to clean the filter cylinder 274, achieving automatic cleaning. The blockage status of the filter cylinder 274 is displayed by an indicator light 2710.

[0019] like Figure 2 As shown, the support frame 1 includes a fixed frame 11, a water tank 16 is fixedly connected to the bottom of the fixed frame 11, a water tank opening 17 is fixedly connected to the top of the water tank 16, a connecting frame 12 is fixedly connected to the top of the fixed frame 11, multiple filter components 2 are fixedly installed on the top of the connecting frame 12, multiple return water pipes 18 are fixedly connected to the top of the water tank 16, the tops of the multiple return water pipes 18 are respectively connected to the pulse switch valves 279 on the side of the multiple filter components 2, a drain pipe 13 is fixedly connected to the right end of the fixed frame 11, a drain nozzle 14 is fixedly connected to the bottom of the drain pipe 13, and a switch valve 15 is provided on the outer surface of the drain nozzle 14.

[0020] The right filter assembly 2 has a water inlet at its top. The connecting water pipe 276 at the bottom of the right filter assembly 2 is connected to the fixed water pipe 21 inside the left filter assembly 2. The aperture of the filter screen cylinders 274 inside the multiple filter assemblies 2 gradually decreases from right to left. The sewage hopper 22 at the bottom of the right filter assembly 2 is connected to the sewage pipe 13. The sewage hopper 22 at the bottom of the left filter assembly 2 is connected to the sewage pipe 13 through the connecting pipe 3. The connecting pipe 3 is equipped with a sewage valve.

[0021] The working process of this utility model is as follows: In use, the water flows through the filter assembly 2 connected end to end. After being filtered by the filter screen 274, the water flows through the fixed cover 271 and enters the interior of the next fixed water pipe 21 through the connecting water pipe 276. It then passes through multiple fixed water pipes 21 and filter screens 274 with gradually decreasing apertures to achieve step-by-step filtration. When a filter cylinder 274 becomes clogged, the corresponding water flow velocity sensor 277 detects a decrease in the water flow velocity in the connecting water pipe 276, thus determining that the filter cylinder 274 is clogged. An electrical signal is then used to control the cleaning brush 26 to rotate on the outer surface of the filter cylinder 274, cleaning it. An indicator light 2710 flashes, and the pulse switch valve 279 activates, causing water from the water tank 16 to be sprayed out of the spray pipe 2711 through the return water pipe 18 and connecting block 278 via the pulse switch valve 279. During the process of the cleaning motor 24 controlling the rotating disk 25 to rotate, the first magnet strip 28 rotates. Through the magnetic attraction of the first magnet strip 28 to the second magnet strip 2713, the water spray pipe 2711 rotates inside the filter screen cylinder 274. At this time, the water inside the water tank 16 backwashes the filter screen cylinder 274 through the water spray pipe 2711. The mud and sand are subjected to gravity and sink into the interior of the sewage hopper 22, and flow into the interior of the sewage pipe 13 through the connecting pipe 3. Finally, by opening the switch valve 15, the sewage is discharged through the sewage outlet 14.
