Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a high-efficiency centrifugal wastewater filtration device for wastewater treatment. Background Technology

[0002] Centrifugal filtration uses centrifugal force to introduce a suspension into a porous drum containing a filter medium (such as a filter screen or filter cloth). Solid particles are trapped by the filter medium, while the liquid flows out through the filter cake layer, thus separating the filtrate and the filter cake. Strictly defined, centrifugal filtration refers only to the stage where a free liquid layer remains on the surface of the filter cake layer, meaning the filter cake layer is always filled with liquid. This stage is rarely used in industry. In practice, centrifugal filtration not only covers the removal of liquid that has seeped into the filter cake layer from the free liquid surface, but sometimes also includes the removal of water used to wash the filter cake. Although centrifugal filtration and centrifugal dehydration operations seem similar, they actually differ significantly in their flow mechanisms and calculation methods.

[0003] Existing wastewater centrifugal filters typically inject wastewater directly into a rotating drum with filter holes for filtration. When the drum rotates, large particles in the wastewater may clog the filter holes, thus affecting the centrifugal filtration effect. Chinese Patent No. CN218166190U discloses a wastewater treatment centrifugal filter. This device includes a tank with a rotatable drum inside. The outer wall of the drum has densely packed filter holes. The tank contains a drive device to rotate the drum, and the drum contains a stirring device. A second drive device to rotate the stirring device is located inside the cover. The output end of the inlet pipe is located above the drum. In use, the drive device is activated to rotate the drum, and water in the wastewater is discharged through the filter holes on the outer wall of the drum. Impurities remain inside the drum, and the discharged water is discharged to the outside of the tank through the outlet. During the rotation of the drum, the stirring device stirs inside the drum to prevent impurities in the wastewater from adhering to the inner wall of the drum and clogging the filter holes, thus affecting normal use.

[0004] However, the above-mentioned device still has obvious defects and shortcomings in practical applications. Although it has a certain centrifugal filtration function, after filtering out impurities, the filtered impurities still remain in the internal centrifugal screen. As filtration continues, the inner wall of the centrifugal screen will gradually be adhered to by impurities, which will lead to blockage during use. It can be seen that the device as a whole lacks an effective slag discharge and anti-blocking function, which has certain limitations in long-term use. After the filter screen is blocked, it will directly lead to a reduction in filtration efficiency. Moreover, when cleaning is required, the operation process is relatively cumbersome and inconvenient. Manually opening the equipment for cleaning will significantly reduce the cleaning efficiency. Obviously, the above-mentioned device lacks an automatic slag discharge and cleaning function, and the overall cleaning operation is cumbersome during use, which needs to be improved in design.

When filtering, the filtrate discharge valve can be opened to discharge the liquid, ensuring that the centrifugal filtration is not disturbed.

Detailed Implementation

[0023] 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.

[0024] Example 1

[0025] A high-efficiency centrifugal wastewater filtration device for wastewater treatment includes a tank 1. A slip ring 2 is rotatably connected to the upper interior of the tank 1. A centrifugal screen 8 is fixedly installed at the bottom of the slip ring 2. A fixing ring 4 is fixedly installed on the upper outer surface of the tank 1. A drive mechanism 6 is fixedly installed on the top of the fixing ring 4. The bottom of the drive mechanism 6 is fixedly connected to the top of the centrifugal screen 8. A slag discharge valve 5 is rotatably connected to the bottom of the tank 1. The input end of the slag discharge valve 5 is connected to the bottom of the centrifugal screen 8, and the input end of the slag discharge valve 5 is connected to the output end of the centrifugal screen 8. A filtrate discharge valve 7 is fixedly installed on the lower side of the tank 1. The input end of the filtrate discharge valve 7 is connected to the output end at the bottom of the tank 1. A stirring mechanism 3 is fixedly installed on the back of the fixing ring 4. The stirring end of the stirring mechanism 3 is located inside the centrifugal screen 8. A support frame 11 is fixedly installed at the front top of the fixing ring 4. A wastewater addition hopper 12 is fixedly installed on the upper end of the support frame 11. The output end of the wastewater addition hopper 12 is located on the tank 1. At the top, during the application of this device, the wastewater to be filtered is injected into the centrifugal screen cylinder 8 through the wastewater filling hopper 12. The wastewater filling hopper 12 can prevent wastewater from overflowing and make the injection process more convenient. The drive mechanism 6 and the stirring mechanism 3 are started, so that the first motor 33 and the second motor 623 run synchronously, driving the centrifugal screen cylinder 8 and the stirring module 34 to rotate at the same speed, generating centrifugal force to achieve solid-liquid separation. Moreover, the two do not scrape each other and will not interfere with the centrifugation process, thus improving the filtration efficiency. During filtration, the liquid passes through the filter core screen cylinder and enters the tank 1. The filtrate discharge valve 7 is opened to discharge the filtrate. After filtration, the first motor 33 and the second motor 623 are controlled to run in opposite directions, so that the stirring module 34 and the centrifugal screen cylinder 8 form relative motion. The scraper plate 343 and the discharge auger 344 rotate in opposite directions. With the help of the conical structure and the slag discharge valve 5, the impurities are discharged through the slag discharge valve 5 by scraping and pushing force. No manual cleaning is required, which solves the problem of impurity accumulation and blockage. After slag discharge, the screen cylinder can be cleaned again, simplifying the cleaning process.

[0026] Combination Figures 1-3As shown, the drive mechanism 6 includes a support frame 61 and a drive assembly 62. The drive assembly 62 is installed on the upper inner side of the stirring mechanism 3. The support frame 61 is fixedly installed on the top of the tank 1. An annular rail 63 is fixedly installed in the middle of the top of the support frame 61. A sliding ring 64 is slidably connected inside the annular rail 63. A connecting frame 65 is fixedly installed at equal intervals in a ring at the bottom of the sliding ring 64. The bottom of the connecting frame 65 is fixedly connected to the top of the sliding ring 2. The stirring mechanism 3 includes a fixed arm 31, which is fixedly installed in the middle of the back of the fixed ring 4. The drive assembly 62 is fixedly installed on the upper inner side of the fixed arm 31. A mounting seat is fixedly installed on the top of the fixed arm 31. 32. A first motor 33 is fixedly installed on the top of the mounting base 32. The output end of the first motor 33 passes through the mounting base and is fixedly installed on the stirring module 34. The stirring module 34 is rotatably connected to the inside of the centrifugal mesh cylinder 8. The outer side of the stirring module 34 is in close contact with the inner wall of the centrifugal mesh cylinder 8. The drive assembly 62 includes a gear ring 621 and a base plate 622. The gear ring 621 is fixedly installed on the top of the sliding ring 64. The base plate 622 is fixedly installed on the upper inner side of the fixed arm 31. A second motor 623 is fixedly installed on the top of the base plate 622. A gear 624 is fixedly installed through the base plate 622. The gear 624 and the gear ring 621 are meshed and connected.

[0027] In the technical solutions described in the embodiments of this application, during the application of this device, the second motor 623 of the drive component 62 drives the gear 624 to rotate. The gear 624 meshes with the gear ring 621, causing the sliding ring 64 to slide along the annular rail 63. Through the connecting frame 65, the sliding ring 2 and the centrifugal screen 8 are rotated, providing power for centrifugal filtration. The cooperation between the annular rail 63 and the sliding ring 64 ensures the stability of rotation and improves the reliability of the centrifugation process. At the same time, the first motor 33 of the stirring mechanism 3 drives the stirring module 34 to operate under the support of the mounting base 32. When the first motor 33 and the second motor 623 run synchronously, The stirring module 34 rotates at the same speed as the centrifugal screen cylinder 8. Since there is no relative movement between the two, the wear and tear on the components due to scraping is avoided. It can also help the sewage to be fully separated under the action of centrifugal force. The liquid enters the tank 1 through the filter holes. After filtration, the first motor 33 and the second motor 623 are controlled to run in opposite directions. The stirring module 34 and the centrifugal screen cylinder 8 form relative movement. The contact between the outer side of the stirring module 34 and the inner wall of the centrifugal screen cylinder 8 makes the scraping more thorough and can effectively remove attached impurities. With the help of the slag discharge structure, the slag is discharged quickly, which solves the problem of impurity blockage in traditional equipment. Throughout the process, all mechanisms work together to improve the efficiency of filtration and cleaning.

[0028] Example 2

[0029] Combination Figures 3-5As shown, the stirring module 34 includes a connecting shaft 341, which is fixedly installed at the bottom output end of the first motor 33. A rotating shaft 342 is fixedly installed at the bottom of the connecting shaft 341. The rotating shaft 342 is rotatably connected to the inside of the centrifugal mesh cylinder 8. Scraper plates 343 are fixedly installed in a ring at equal intervals on the outer surface of the rotating shaft 342. The outer side of the scraper plates 343 is in close contact with the inner wall of the centrifugal mesh cylinder 8. A discharge auger 344 is fixedly installed at the lower end of the outer surface of the rotating shaft 342. The discharge auger 344 is rotatably connected to the bottom of the centrifugal mesh cylinder 8. The outer surface of the discharge auger 344 is in close contact with the bottom of the centrifugal mesh cylinder 8. The lower ends of the centrifugal mesh cylinder 8, the tank 1, and the stirring auger are all conical. Support legs 9 are fixedly installed in a ring at equal intervals on the bottom of the fixing ring 4. A support bottom ring 10 is fixedly installed at the bottom of the support legs 9.

[0030] In the above-described embodiments of this application, during the application of this device, the first motor 33 drives the connecting shaft 341 and the rotating shaft 342 to rotate, causing the scraper 343 and the discharge auger 344 to rotate inside the centrifugal screen cylinder 8 along with the rotating shaft 342. When the first motor 33 and the second motor 623 run synchronously, the scraper 343 and the discharge auger 344 rotate at the same speed as the centrifugal screen cylinder 8. Since there is no relative motion, scraping and wear on the inner wall of the centrifugal screen cylinder 8 are avoided. At the same time, it assists in accelerating the separation of sewage under the action of centrifugal force, and the liquid smoothly passes through the filter holes. After filtration, the first motor 33 and the second motor 623 run in opposite directions, scraping... The wiping plate 343 rotates with the rotating shaft 342, forming relative motion with the inner wall of the centrifugal screen cylinder 8, which can scrape off the attached impurities. The discharge auger 344 rotates synchronously and generates relative friction with the bottom of the centrifugal screen cylinder 8, pushing the impurities to the bottom. Since the lower ends of the centrifugal screen cylinder 8, tank 1 and discharge auger 344 are conical, the impurities accumulate at the slag discharge point under the action of gravity and pushing force, and are quickly discharged with the help of the slag discharge structure, which solves the problem of impurity accumulation and blockage. The support leg 9 and the support bottom ring 10 provide stable support for the entire device, avoiding shaking during operation and ensuring stable and efficient filtration and slag discharge processes, thus improving the overall reliability of the equipment.

[0031] The working principle and advantages of this utility model are as follows: The tank 1 is placed in a designated position by the support legs 9 and the support bottom ring 10. The support legs 9 and the support bottom ring 10 cooperate to provide stable support, which can prevent shaking during equipment operation. Check that the slag discharge valve 5 and the filtrate discharge valve 7 are in the closed state to ensure that the centrifugal screen 8 can normally contain sewage. The drive mechanism 6 and the stirring mechanism 3 are in the initial position. The output end of the sewage addition hopper 12 on the support frame 11 is aligned with the top of the tank 1. The sewage to be filtered is poured into the sewage addition hopper 12. The sewage flows into the top of the tank 1 through the addition hopper and enters the centrifugal screen 8. This process can prevent sewage overflow and make the injection operation more convenient. Start the second motor 623 of the drive assembly 62 and the first motor 3 of the stirring mechanism 3. 3. To ensure synchronous operation, the first motor 33 drives the gear 624 to rotate, which in turn meshes with the gear ring 621 to cause the sliding ring 64 to slide along the annular track 63. Through the connecting frame 65, the sliding ring 2 and the centrifugal screen 8 are rotated. At the same time, the first motor 33 drives the connecting shaft 341 and the rotating shaft 342 to rotate the stirring module 34. The stirring module 34 and the centrifugal screen 8 rotate synchronously to generate centrifugal force. Since the two rotate at the same speed, they will not scrape each other, which can avoid the stirring module 34 from affecting the centrifugation process. After the sewage is filtered, the liquid in it enters the tank 1 through the filter hole, and the solid impurities are intercepted to achieve solid-liquid separation. Synchronous operation ensures the high efficiency of centrifugal filtration. During filtration, the filtrate can be discharged simply by opening the filtrate discharge valve 7.

[0032] During use, after filtration is complete, the first motor 33 and the second motor 623 are adjusted to run in opposite directions, causing the stirring module 34 and the centrifugal screen 8 to move relative to each other. At this time, the scraper 343 generates relative friction with the inner wall of the centrifugal screen 8, and the stirring auger also rotates in the opposite direction to the centrifugal screen 8. Then, the slag discharge valve 5 is opened. Since the lower ends of the centrifugal screen 8, the tank 1, and the discharge auger 344 are conical, under the influence of gravity, the pushing force of the discharge auger 344 rotating in the opposite direction, and the scraping force generated by the reverse rotation, the impurities are quickly discharged through the slag discharge valve 5 without manual intervention. The cleaning process solves the problem of cumbersome cleaning of existing equipment, allowing the equipment to quickly and conveniently discharge filter residue. After discharge, the motor can be controlled to continue running in reverse for a period of time, allowing the scraper 343 and the discharge auger 344 to further clean the inside of the centrifugal screen cylinder 8. Throughout the process, the support leg 9 and the support bottom ring 10 ensure stable operation of the equipment. The coordinated work of each mechanism simplifies the operation process, reduces maintenance costs, and improves the practicality of the equipment. During the application of this equipment, a chassis can be installed on one side, and a PLC controller and a motor synchronization controller can be installed inside the chassis.

[0033] During the application of this device, the diameter of the centrifugal screen cylinder 8 ranges from 500-800mm, the length ranges from 800-1200mm, and the filter hole diameter ranges from 2-5mm; the diameter of the discharge auger 344 ranges from 150-250mm, and the pitch ranges from 100-200mm; the height of the support leg 9 ranges from 600-1000mm, and the diameter of the support bottom ring 10 ranges from 1000-1500mm; the first motor 33 is a three-phase asynchronous motor of model Y2-132M-4 with a power range of 7.5-11kW; the second motor 623 is a model Y2-112M... The three-phase asynchronous motor has a power range of 4-5.5kW; the solenoid valve is a 2W-250-25 two-position two-way solenoid valve with an operating voltage of AC220V. The electronic components are connected by copper core cables and powered by a 380V three-phase AC power supply. They are connected to the circuit in parallel. The controller is an S7-200SMART PLC, which is installed in the control box on the side of the fixed ring 4. The control box is fixed on the side of the fixed ring 4 near the stirring mechanism 3. It is connected to the first motor 33, the second motor 623, and the solenoid valve through wires to realize the operation control of each component.

[0034] The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.

[0035] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
