Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment, in particular to sewage microfiltration equipment. Background Art

[0002] Microfiltration, also known as microporous filtration, is a type of precision filtration. It is widely used in terminal filtration of ultrapure water in the microelectronics industry, pretreatment of various industrial water supplies and treatment of drinking water. It is also an important tool for detecting fine impurities and conducting scientific experiments in biomedicine and cutting-edge technology. Filter membranes are divided into four types according to the size of the micropores: microfiltration membranes, ultrafiltration membranes, nanofiltration membranes and reverse osmosis membranes. Among them, microfiltration membranes are a commonly used membrane in microfiltration equipment.

[0003] With the growth of population, people generate more and more domestic sewage, which is input into sewage treatment plants through pipes. The sewage is filtered many times by multiple filtering equipment in the sewage treatment plants, and the impurities in the sewage are filtered and precipitated through multiple processes so that the sewage reaches the standard of drinkable water. Before the sewage reaches the standard of drinkable water, it needs to be filtered by microfiltration equipment.

[0004] The existing microfiltration equipment generally injects sewage into the equipment, and the flow velocity direction of the water flow in the equipment is perpendicular to the filter screen, so that the sewage passes through the filter screen under the push of pressure, and the impurities in the sewage remain on the filter screen. However, with the increase of time, more and more impurity particles accumulate on the filter screen, causing the filtration speed of the filter screen to decrease. It is necessary to stop and disassemble the filter screen for cleaning, and cleaning the filter screen is very troublesome, time-consuming and labor-intensive, which reduces the overall speed of sewage treatment. In addition, when filtering sewage, the existing microfiltration equipment is prone to vibration due to the thrust of water, and the shock-absorbing device of the existing microfiltration equipment can generally only achieve shock absorption in the vertical direction, and the shock absorption direction is single, so that when the microfiltration equipment is subjected to lateral vibration, it is easy to have position displacement, which is not conducive to the normal operation of the microfiltration equipment. Summary of the invention

[0005] The present invention aims to solve the shortcomings existing in the background technology and provide a sewage microfiltration device.

Through the coordinated use of a shock-absorbing block, a torsion spring, a support column and a buffer spring, shock absorption in the vertical and horizontal directions can be achieved.

[0006] To achieve the above object, the present invention provides the following technical solution: a sewage microfiltration device, comprising a housing, a rotating disc, a shock absorbing block and a cleaning assembly;

[0010] Furthermore, a movable groove is provided on one side of the fixed block close to the microfiltration cartridge, and the scraper protrudes from the outer surface of the fixed block through the movable groove, and the scraper is in contact with the surface of the microfiltration cartridge.

[0011] Furthermore, the bottom of the servo motor is driven and connected to a rotating rod, the bottom of the rotating rod is fixedly connected to a gear, a gear bar is arranged on the outside of the rotating disk, and the gear is meshed and connected to the rotating disk through the gear bar, and the servo motor is electrically connected to the control panel.

[0012] Furthermore, a plurality of impellers are fixedly connected to the outside of the microfiltration cartridge, and the plurality of impellers are evenly arranged in a circular array, a chassis is fixedly connected to the bottom of the microfiltration cartridge, a plurality of pulleys are arranged at the bottom of the chassis, an annular groove is opened on the inner wall of the bottom of the box body, and the pulley is located inside the annular groove.

[0013] Furthermore, a sewage pipe and a water outlet pipe are fixedly connected to one side of the box body, and the water outlet pipe is located below the sewage pipe.

[0014] Furthermore, a drain pipe is fixedly connected to the bottom of the box body, and the drain pipe passes through the chassis and is connected to the inside of the microfiltration cartridge. A water inlet pipe is fixedly connected to the top of the box body, and the water inlet pipe passes through the box body and is inserted into the inside of the microfiltration cartridge. A plurality of nozzles are arranged on the outside of the water inlet pipe. Solenoid valves are arranged on the sewage pipe, the outlet pipe, the drain pipe and the inlet pipe, and the solenoid valve is electrically connected to the control panel.

[0015] Furthermore, a plurality of fixing rods are fixedly connected to the bottom of the box body, a slot is provided at the bottom of the shock absorbing block, and the fixing rod passes through the shock absorbing block and is inserted into the slot, a plurality of torsion springs are arranged inside the slot, one end of the torsion spring is connected to the fixing rod, and the other end of the torsion spring is connected to the inner wall of the slot, and the plurality of torsion springs are evenly arranged and distributed in a circular array.

[0017] The present invention provides a sewage microfiltration device, which has the following beneficial effects:

[0018] 1. The advantage of the present invention is that when it is necessary to microfilter sewage, the microfilter cartridge drives the sewage inside the box to rotate through multiple impellers through the sewage pipe, control panel, servo motor, rotating rod, gear, gear bar, and rotating disk, so that impurities in the sewage are away from the microfilter cartridge under the action of centrifugal force, thereby improving the filtering effect of the microfilter cartridge, and the flow direction of the sewage is relatively parallel to the surface of the microfilter cartridge, so that the sewage flows along the surface of the microfilter cartridge, generating shear force on the impurities on the surface of the microfilter cartridge, so that part of the impurities return to the water flow, thereby reducing the amount of impurities attached to the surface of the microfilter cartridge, so that the filtering speed of the microfilter cartridge is maintained at a higher level for a relatively long period of time.

[0019] 2. Secondly, when the microfilter cartridge rotates, the scraper can always be in close contact with the outer surface of the microfilter cartridge through the moving plate, fixed block and reset spring, so that the impurities on the outer surface of the microfilter cartridge can be scraped off by the scraper while the microfilter cartridge rotates, preventing a large amount of impurities from clogging the microfilter cartridge, causing the overall filtration speed to decrease, thereby improving the filtration effect.

[0020] 3. Then, when the microfilter cartridge needs to be cleaned, clean water is sprayed onto the microfilter cartridge through the control panel, water inlet pipe and nozzle, and the impurities adhering to the microfilter cartridge are backflushed, so that the impurities fall off and are separated from the microfilter cartridge. At the same time, the servo motor is started to rotate the microfilter cartridge, so that the clean water sprayed from the nozzle can completely cover the microfilter cartridge, and the impurities flushed out of the microfilter cartridge are thrown out under the action of centrifugal force, thereby improving the cleaning effect. When the microfilter cartridge rotates, the impurities flushed out to the surface of the microfilter cartridge are scraped off by the scraper, and the microfilter cartridge is cleaned to the maximum extent. The cleaned water is discharged through the outlet pipe, and the cleaning of the microfilter cartridge is completed. There is no need to replace the microfilter cartridge, saving sewage treatment costs and improving sewage treatment speed.

[0021] 4. Furthermore, when the box is vibrated by a lateral force, the elastic force generated by the torsion spring and the lateral force are offset by the fixed rod and the torsion spring, thereby reducing the lateral vibration of the box. When the box is vibrated by a vertical force, the elastic force generated by the shock-absorbing spring and the vertical force are offset by the shock-absorbing block, the pressing plate and the shock-absorbing spring, thereby reducing the vertical vibration of the box.

[0033] Example:

[0034] See also Figure 1-10 middle,

[0035] The present embodiment provides a sewage microfiltration device, comprising a housing 1, a rotating disc 3, a shock absorbing block 5 and a cleaning assembly;

[0036] A control panel 105 is fixedly installed on the front of the box 1, a rotating disk 3 is arranged inside the box 1, a microfiltration cartridge 302 with a hollow structure inside is fixedly connected to the bottom of the rotating disk 3, a plurality of shock absorbing blocks 5 are arranged at the bottom of the box 1, and a servo motor 2 is fixedly installed on one side of the top of the box 1;

[0037] A cleaning assembly is provided between the housing 1 and the microfiltration cartridge 302 for cleaning impurities on the microfiltration cartridge 302 .

[0038] The box body 1 is made of stainless steel, which has good corrosion resistance and high mechanical strength, so that the box body 1 can resist corrosion from sewage and impurities in sewage for a long time, thereby extending the service life of the box body 1. The high mechanical strength makes the box body 1 have a certain strength and hardness, so that the box body 1 can resist impact from external foreign objects and withstand the water pressure inside the box body 1.

[0039] At the same time, the box body 1 can also be made of aluminum alloy material, which also has the characteristics of good corrosion resistance and high mechanical strength, and can meet the production requirements of the box body 1. When the aluminum alloy material is compared with the stainless steel material, the corrosion resistance of the stainless steel material is higher than that of the aluminum alloy material. Since the box body 1 is in contact with sewage for a long time, it is preferred to choose stainless steel material with good corrosion resistance for its production.

[0040] Furthermore, the cleaning component includes a fixed block 4, a return spring 401, a movable plate 402 and a scraper 403. Two fixed blocks 4 with hollow structures are fixedly installed on the inner wall of one side of the box body 1. The movable plate 402 is arranged inside the fixed block 4. The movable plate 402 is fixedly connected to a side of the movable plate 402 away from the microfiltration cartridge 302 with multiple return springs 401, and one end of the return spring 401 away from the movable plate 402 is connected to the inner wall of the fixed block 4, and the movable plate 402 is fixedly connected to a side of the movable plate 402 away from the return spring 401. The scraper 403 is fixedly connected to the side of the movable plate 402 away from the return spring 401. When the microfiltration cartridge 302 rotates, the microfiltration cartridge 302 will sway slightly during rotation. At this time, the microfiltration cartridge 302 applies a thrust to the scraper 403, so that the scraper 403 drives the movable plate 402 to move into the fixed block 4, so that the return spring 401 is squeezed and elastically deformed to generate elastic force, and the generated elastic force acts on the scraper 403 through the movable plate 402, so that the scraper 403 can always be close to the outer surface of the microfiltration cartridge 302.

[0041] Furthermore, a movable groove is provided on one side of the fixed block 4 close to the microfilter cartridge 302, and a scraper 403 protrudes from the outer surface of the fixed block 4 through the movable groove, and the scraper 403 is in contact with the surface of the microfilter cartridge 302, so that when the microfilter cartridge 302 rotates, impurities on the outer surface of the microfilter cartridge 302 are scraped off by the scraper 403, thereby preventing a large amount of impurities from clogging the microfilter cartridge 302 and causing the overall filtration speed to decrease, thereby improving the filtration effect.

[0042] Furthermore, the bottom of the servo motor 2 is driven and connected to a rotating rod 201, and the bottom of the rotating rod 201 is fixedly connected to a gear 202. A gear bar 301 is provided on the outer side of the rotating disk 3, and the gear 202 is meshed and connected with the rotating disk 3 through the gear bar 301. The servo motor 2 is electrically connected to the control panel 105. When the microfiltration cartridge 302 is microfiltering sewage, the servo motor 2 is started through the control panel 105, so that the servo motor 2 drives the gear 202 to rotate through the rotating rod 201, and the gear 202 is meshed and connected with the rotating disk 3 through the gear bar 301, so that the gear 202 drives the rotating disk 3 to rotate through the gear bar 301, thereby driving the microfiltration cartridge 302 to rotate.

[0043] Furthermore, a plurality of impellers 303 are fixedly connected to the outside of the microfilter cartridge 302, and the plurality of impellers 303 are evenly arranged in an annular array. A chassis 304 is fixedly connected to the bottom of the microfilter cartridge 302, and a plurality of pulleys 305 are arranged at the bottom of the chassis 304. An annular groove 306 is provided on the inner wall of the bottom of the casing 1, and the pulley 305 is located inside the annular groove 306. When the microfilter cartridge 302 rotates, the sewage inside the casing 1 is driven to rotate by the plurality of impellers 303 on the outside of the microfilter cartridge 302, so that impurities in the sewage are moved away from the microfilter cartridge 302 under the action of centrifugal force, thereby improving the filtering effect of the microfilter cartridge 302. At the same time, the microfilter cartridge 302 drives the chassis 304 to rotate, and the rotation direction and path of the microfilter cartridge 302 are limited by the pulley 305 and the annular groove 306, so as to avoid the microfilter cartridge 302 from deviating during rotation, thereby reducing the filtering effect of the microfilter cartridge 302 on sewage.

[0044] Furthermore, a sewage pipe 101 and an outlet pipe 102 are fixedly connected to one side of the box body 1, and the outlet pipe 102 is located below the sewage pipe 101. The sewage that needs microfiltration is injected into the box body 1 through the sewage pipe 101. After the sewage is filtered through the microfiltration cartridge 302, the solenoid valve on the drain pipe 103 is opened through the control panel 105, so that the filtered sewage is discharged through the drain pipe 103.

[0045] Furthermore, a drain pipe 103 is fixedly connected to the bottom of the box body 1, and the drain pipe 103 passes through the chassis 304 and is connected to the inside of the microfiltration cartridge 302. A water inlet pipe 104 is fixedly connected to the top of the box body 1, and the water inlet pipe 104 passes through the box body 1 and is inserted into the inside of the microfiltration cartridge 302. A plurality of nozzles are arranged on the outside of the water inlet pipe 104. Solenoid valves are arranged on the sewage pipe 101, the outlet pipe 102, the drain pipe 103 and the water inlet pipe 104. The solenoid valve is electrically connected to the control panel 105. After the microfiltration cartridge 302 has filtered the sewage for a long time, a large amount of impurities that cannot be scraped off by the scraper 403 adhere to the microfiltration cartridge 302. At this time, the microfiltration cartridge 302 needs to be cleaned. The solenoid valve of the water inlet pipe 104 is opened through the control panel 105, so that clean water enters the microfiltration cartridge 302 through the water inlet pipe 104. At the same time, the solenoid valve on the drain pipe 103 is closed through the control panel 105. To prevent clean water from being discharged through the drain pipe 103, the clean water is then sprayed onto the microfilter cartridge 302 through multiple nozzles, and the impurities adhering to the microfilter cartridge 302 are backwashed, so that the impurities fall off and are separated from the microfilter cartridge 302. At the same time, the servo motor 2 is started through the control panel 105, so that the servo motor 2 drives the microfilter cartridge 302 to rotate through the gear 202 and the gear bar 301, so that the clean water sprayed by the nozzle can completely cover the microfilter cartridge 302, and the impurities flushed out of the microfilter cartridge 302 are thrown out under the action of centrifugal force, thereby improving the cleaning effect. When the microfilter cartridge 302 rotates, the scraper 403 scrapes off the impurities flushed out to the surface of the microfilter cartridge 302, and the microfilter cartridge 302 is cleaned to the maximum extent. The cleaned water is discharged through the outlet pipe 102, and the cleaning of the microfilter cartridge 302 is completed. There is no need to replace the microfilter cartridge 302, thereby saving sewage treatment costs.

[0046] Furthermore, a plurality of fixing rods 106 are fixedly connected to the bottom of the box body 1, a groove is provided at the bottom of the shock absorbing block 5, and the fixing rod 106 passes through the shock absorbing block 5 and is inserted into the groove, and a plurality of torsion springs are fixedly connected to the outside of the fixing rod 106, and one end of the torsion spring 503 away from the fixing rod 106 is connected to the inner wall of the groove, and a plurality of torsion springs 503 are evenly arranged and distributed in a circular array. Then, when the sewage is treated, the sewage is driven to rotate due to the rotation of the microfiltration cartridge 302, so that the box body 1 is vibrated by the thrust of the sewage. When the box body 1 is vibrated by the lateral force, the box body 1 drives the fixing rod 106 to rotate. At this time, the torsion spring 503 is stretched or bent, and elastic deformation occurs to generate elastic force, so that the elastic force generated by the torsion spring 503 and the lateral force offset each other, thereby reducing the lateral vibration of the box body 1.

[0047] Furthermore, a pressing plate 501 is fixedly connected to the inside of the groove, a pressing hole 502 is provided on the pressing plate 501, a supporting column 504 matching the pressing hole 502 is arranged inside the pressing hole 502, a supporting seat 506 is fixedly connected to the bottom of the supporting column 504, a shock-absorbing spring 505 is arranged between the pressing plate 501 and the supporting seat 506, and the shock-absorbing spring 505 is sleeved on the supporting column 504. When the box body 1 is vibrated by the force in the vertical direction, the box body 1 drives the pressing plate 501 to move through the shock-absorbing block 5, so that the shock-absorbing spring 505 is elastically deformed by the squeezing of the pressing plate 501 to generate elastic force, so that the elastic force generated by the shock-absorbing spring 505 offsets the force in the vertical direction, so as to reduce the vibration of the box body 1 in the vertical direction, and avoid the vibration generated by the box body 1 when the box body 1 treats sewage, The vibration is transmitted to the support seat 506, causing the support seat 506 to be offset.

[0048] When using the present invention, when it is necessary to microfilter sewage, the sewage to be microfiltered is injected into the box body 1 through the sewage pipe 101, and then the servo motor 2 is started through the control panel 105, so that the servo motor 2 drives the gear 202 to rotate through the rotating rod 201, and the gear 202 is meshed with the rotating disk 3 through the gear bar 301, so that the gear 202 drives the rotating disk 3 to rotate through the gear bar 301, and then drives the microfiltration cartridge 302 to rotate. When the microfiltration cartridge 302 rotates, the sewage inside the box body 1 is driven to rotate through the multiple impellers 303 outside the microfiltration cartridge 302, so that the impurities in the sewage are moved away from the microfiltration cartridge 302 under the action of centrifugal force, thereby improving the filtering effect of the microfiltration cartridge 302 and the sewage. The flow direction is relatively parallel to the surface of the microfilter cartridge 302, so that the sewage flows along the surface of the microfilter cartridge 302, generating shear force on the impurities on the surface of the microfilter cartridge 302, causing some of the impurities to return to the water flow, thereby reducing the amount of impurities attached to the surface of the microfilter cartridge 302, so that the filtration speed of the microfilter cartridge 302 is maintained at a relatively high level for a relatively long period of time. At the same time, the microfilter cartridge 302 drives the chassis 304 to rotate, and the rotation direction and path of the microfilter cartridge 302 are limited by the pulley 305 and the annular groove 306 to prevent the microfilter cartridge 302 from deviating during rotation, causing the microfilter cartridge 302 to reduce the filtration effect of the sewage. Then, the impurities in the sewage are filtered by the microfilter cartridge 302, so that the impurities remain on the outer surface of the microfilter cartridge 302, while the microfilter cartridge 302 When the filter cartridge 302 rotates, the microfilter cartridge 302 will sway slightly during the rotation. At this time, the microfilter cartridge 302 applies a thrust to the scraper 403, so that the scraper 403 drives the movable plate 402 to move into the fixed block 4, so that the return spring 401 is squeezed and elastically deformed to generate elastic force, and the generated elastic force acts on the scraper 403 through the movable plate 402, so that the scraper 403 can always be close to the outer surface of the microfilter cartridge 302, so that the microfilter cartridge 302 can scrape off the impurities on the outer surface of the microfilter cartridge 302 through the scraper 403 while rotating, so as to prevent a large amount of impurities from clogging the microfilter cartridge 302, causing the overall filtration speed to decrease, and improve the filtration effect, and then open the solenoid valve on the drain pipe 103 through the control panel 105, so that The filtered sewage is discharged through the drain pipe 103, and the filtration of the sewage is completed. After the microfilter cartridge 302 has filtered the sewage for a long time, a large amount of impurities that cannot be scraped off by the scraper 403 adhere to the microfilter cartridge 302. At this time, the microfilter cartridge 302 needs to be cleaned. The solenoid valve of the water inlet pipe 104 is opened through the control panel 105, so that clean water enters the microfilter cartridge 302 through the water inlet pipe 104. At the same time, the solenoid valve on the drain pipe 103 is closed through the control panel 105 to prevent the clean water from being discharged through the drain pipe 103. Then, the clean water is sprayed onto the microfilter cartridge 302 through multiple nozzles to backwash the impurities adhered to the microfilter cartridge 302, so that the impurities fall off and are separated from the microfilter cartridge 302. At the same time, the servo motor 2 is started through the control panel 105.The servo motor 2 drives the microfilter cartridge 302 to rotate through the gear 202 and the gear bar 301, so that the clean water sprayed by the nozzle can completely cover the microfilter cartridge 302, and the impurities flushed out of the microfilter cartridge 302 are thrown out under the action of centrifugal force, thereby improving the cleaning effect. When the microfilter cartridge 302 rotates, the impurities flushed out to the surface of the microfilter cartridge 302 are scraped off by the scraper 403, and the microfilter cartridge 302 is cleaned to the maximum extent. The cleaned water is discharged through the outlet pipe 102, and the cleaning of the microfilter cartridge 302 is completed. There is no need to replace the microfilter cartridge 302, thereby saving sewage treatment costs and improving sewage treatment speed. Then, when the microfilter cartridge 302 rotates, the sewage is driven to rotate through the impeller 303, so that the box body 1 is vibrated by the thrust of the sewage. When the box body 1 is vibrated by the lateral force, the box body 1 The fixing rod 106 is driven to rotate in the direction. At this time, the torsion spring 503 is stretched or bent, and elastically deforms to generate elastic force, so that the elastic force generated by the torsion spring 503 and the force in the horizontal direction offset each other, thereby reducing the vibration of the box body 1 in the horizontal direction. When the box body 1 is vibrated by the force in the vertical direction, the box body 1 drives the pressing plate 501 to move through the shock-absorbing block 5, so that the shock-absorbing spring 505 is squeezed by the pressing plate 501 and elastically deforms to generate elastic force, so that the elastic force generated by the shock-absorbing spring 505 and the force in the vertical direction offset each other, so as to reduce the vibration of the box body 1 in the vertical direction, and avoid the vibration generated by the box body 1 when the box body 1 is treating sewage. The support seat 506 is prevented from being offset. The above structure can play a role in shock absorption and clean the microfiltration cartridge 302.
