Description

Technical Field

[0001] The present invention relates to the technical field of cooling water treatment, and specifically to a secondary filtration device for cooling water. Background Art

[0002] Cooling water refers to the circulating water used to cool equipment or systems in industries, energy, transportation and other fields. Its core function is to reduce the temperature of the target object through heat exchange to ensure the safe and stable operation of the equipment. During the operation of the cooling equipment or system, dust, algae spores, insect debris, etc. in the air will be continuously inhaled, or scale precursors (such as calcium carbonate crystal nuclei, metal corrosion products) will be generated due to water quality concentration. If these impurities are not removed in time, particles or impurities may enter the interior of the equipment, causing blockages in components such as pipes, valves, and nozzles, affecting the normal operation of the equipment. Therefore, special equipment is required to treat it.

[0003] When treating the used cooling water sewage that needs to be treated in the sewage treatment process, generally the cooling water sewage is first passed into a filter or a filter plate to initially filter the impurities in the cooling water sewage. Subsequently, the filtered cooling water sewage is passed into a sedimentation tank, and an appropriate amount of flocculant is added to it to make the flocculant more completely settle with the impurities in the cooling water sewage. Subsequently, after re - filtration, it is discharged through the water outlet. The impurities after the first filtration will adhere to the filter or the filter plate. After a long time, it will cause blockage of the filter or the filter plate. At this time, the cooling water sewage treatment device needs to be shut down for maintenance, thus affecting the efficiency of cooling water sewage treatment. Therefore, we have designed a secondary filtration device for cooling water to solve the above problems. Summary of the Invention

[0008] As a further solution of the present invention: The rotating assembly includes a connecting plate fixedly connected to the inner side of the second filter cylinder, and the connecting plate is fixedly connected to the second cylinder. A connecting block is arranged inside the second cylinder. A rotating shaft is rotatably connected to the inside of the connecting block.

[0009] As a further solution of the present invention: The rotating assembly further includes two first driving motors installed on the top of the connecting plate.

[0011] As a further solution of the present invention: Multiple sections of helical teeth are arranged at the bottom of the bevel gear ring, and the multiple sections of helical teeth are intermittently distributed around the bottom of the bevel gear ring.

[0013] As a further solution of the present invention: Coupling grooves are respectively formed inside the first isolation plate, the second isolation plate, the third isolation plate and the fourth isolation plate. A driving rod is fixedly connected to each of the first isolation plate, the second isolation plate, the third isolation plate and the fourth isolation plate. The size of the coupling plate matches that of the coupling groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are: By setting up an impurity removal mechanism, the cooling water enters the inner side of the second filter cartridge from the first connecting pipe on the right side for filtration, and the filtered cooling water flows into the inner side of the first filter cartridge through the third connecting pipe to flush the impurities inside the first filter cartridge, so that the two filter cartridges are alternately in the "filtering state" and the "backwashing cleaning state", so that the filter cartridges can be automatically cleaned without stopping the machine, thereby improving the continuity of the system. At the same time, the two filter cartridges take on the filtering task alternately to avoid a single filter screen from being subjected to water flow impact and impurity friction for a long time, thereby extending the service life of the filter cartridge. At the same time, the two-way booster pump boosts the filtered cooling water, so that the filtered cooling water forms sputtering, thereby increasing the pressure of the water impact, thereby improving the cleaning effect of the filter cartridge, so that the device can be continuously operated when treating cooling water sewage, without frequent shutdown maintenance operations, thereby improving the efficiency of cooling water sewage treatment; 2. By setting a rotating assembly, the second rotating shaft is driven to rotate, thereby driving the second connecting block to rotate, so that the second filter cartridge can rotate. When the water flow backwashes the second filter cartridge, the second filter cartridge can rotate, so that different parts of the second filter cartridge are contacted with the water flow in turn, so as to fully clean the inside of the second filter cartridge. At the same time, the rotation will increase the speed of impurities falling off the inside of the second filter cartridge, and at the same time, the centrifugal force will assist the water flow to peel off the attachments, thereby improving the backwashing effect; 3. By setting up an up and down shaking mechanism, the second rotating shaft is driven to continue to rotate. At this time, the second rotating shaft is pushed to reset under the action of the second torsion spring, thereby driving the second filter cartridge to reset. In this way, the second filter cartridge can be rotated for backwashing, and the second filter cartridge can be synchronously swung up and down, and cooperate with the water flow to flush from the outside to the inside, so as to destroy the adhesion between impurities and the filter screen, especially for sticky impurities such as flocculants, colloids or fine particles. The vibration can make them loosen and fall off from the filter holes, significantly improving the backwashing effect. The up and down swinging causes the direction and angle of the backwashing water flow to change periodically, forming a complex turbulent field. The turbulence can enhance the flushing force of the water flow on the filter screen, especially for the blockage inside the filter hole. It has a stronger ability to remove; 4. By setting the cooperation of parts such as the filter cartridge, when the water to be filtered enters from the top of the second filter cartridge, the entire filter surface passes through the water flow in sequence, ensuring that each mesh hole can participate in the filtration evenly, avoiding the accumulation of impurities in "dead corners", thereby increasing the effective filtration area per unit time. Rotating the first filter cartridge can disperse the wear by rotating each part in turn to contact the water flow and impurities, making the overall wear more uniform and reducing the replacement cost, thereby improving the filtration efficiency and reducing the operation and maintenance cost. At the same time, during the rotation of the first filter cartridge, in cooperation with the water flow entering from the top, a centrifugal force is generated so that the impurities filtered by the first filter cartridge can be thrown from the filter mesh of the first filter cartridge to the bottom, thereby enabling the first filter cartridge to continuously filter when filtering cooling water; 5. By setting the cooperation of parts such as the bevel gear ring, the first filter cartridge is driven to swing up and down, so that the first filter cartridge can swing up and down during filtration, and then by mechanical forces such as the pushing and meshing of helical teeth, a reciprocating vibration or displacement is applied to the filter mesh, forming an effect similar to "rotary scrubbing", thereby enhancing the impurity stripping ability and reducing the residue of impurities on the filter mesh, and further improving the filtering effect of the filter mesh; 6. By setting the impurity deposition mechanism, the space above and below the first partition plate is closed, and the space above and below the third partition plate is opened, so that the impurities on the top of the third partition plate can fall to the bottom of the fourth partition plate. At the same time, since the bottom of the fourth partition plate is completely isolated from the filter cartridge, the water flow channel is blocked, forming a temporary "collection bin", so that the impurities are temporarily stored on the top of the third partition plate, avoiding the impurities directly falling to the bottom of the sludge storage cylinder or flowing back with the water flow. At the same time, after blocking the water flow, the impurities are not affected by the water flow impact when falling, and can be quickly and stably deposited to the bottom of the sludge storage cylinder, improving the deposition efficiency.

The impurity removal mechanism includes two second cylinders 11 arranged inside the second filter cylinder 3. Rubber plates 12 are fixedly connected to the inner sides of the two second cylinders 11. A first rotating ring 38 is fixedly connected to the inner side of the rubber plate 12. A filter cylinder 21 is rotatably connected to the outer wall of the first rotating ring 38. A two-way booster pump 13 is arranged inside the second filter cylinder 3, and the two-way booster pump 13 is fixedly connected to the two second cylinders 11 through pipelines. A first solenoid valve 10 is installed at the water outlet on each side of the first cylinder 4. One end of each of the two first solenoid valves 10 is installed with a first connecting pipe 6. The other ends of the two first connecting pipes 6 are respectively installed at the water inlet of a second cylinder 11; a second driving motor 41 is installed at one end of the first cylinder 4, and the output end of the second driving motor 41 penetrates into the inner side of the first cylinder 4 and is fixedly connected with a stirring ring 42. Two second fixing rods 43 are fixedly connected to the top of the first cylinder 4. A medicine box 45 is fixedly connected to the tops of the two second fixing rods 43. The output end of the medicine box 45 is installed with a third solenoid valve 44, and the other end of the third solenoid valve 44 is fixedly connected to the input end of the first cylinder 4; the impurity removal mechanism further includes a second solenoid valve 28 installed at the water outlet of the second cylinder 11. An isolation chamber 27 is fixedly connected to the inner side of the second filter cylinder 3, and the isolation chamber 27 is fixedly connected with the second cylinder 11. A rubber ring 26 is fixedly connected to the inner side of the rubber plate 12. A second rotating ring 39 is fixedly connected to the top of the rubber ring 26, and the second rotating ring 39 is rotatably connected with the filter cylinder 21. A sludge storage cylinder 7 is fixedly connected to the inner side of the second cylinder 11, and the rubber ring 26 is fixedly connected with the sludge storage cylinder 7. A rotating assembly is arranged at the top of the filter cylinder 21; The second driving motor 41 is controlled by a PLC controller, and the intermittent start of the second driving motor 41 can be controlled. A switch is arranged inside the third solenoid valve 44 to control the opening and closing of the pipeline. The water inlet pipe 5 is connected to the cooling water drain pipe to be processed outside. When the staff opens the switch of the external cooling water drain pipe and pours the cooling water to be processed into the inside of the first cylinder 4, at this time, the PCL controller controls the second driving motor 41 to start, so as to drive the stirring ring 42 to rotate, thereby stirring the cooling water. At the same time, a flocculant is arranged inside the medicine box 45. When the second driving motor 41 starts, at this time, the staff opens the switch inside the third solenoid valve 44, so that the medicine box 45 can continuously feed the inside of the first cylinder 4, so that the flocculant and the impurities in the cooling water settle, thereby improving the filtering effect of the cooling water; A quartz sand layer, an activated carbon layer and a fiber ball layer are arranged inside the first filter cylinder 2. After the cooling water is initially filtered through the second filter cylinder 3, the filtered cooling water is then filtered a second time through the quartz sand layer, the activated carbon layer and the fiber ball layer, and finally discharged through the water outlet. Since this technology is an existing technology, it is not specifically described in this solution; The first solenoid valve 10, the second solenoid valve 28, and the two-way booster pump 13 are all controlled by a PLC controller. The PLC controller can control the first solenoid valve 10 and the second solenoid valve 28 to open and start. At this time, the PLC controller controls the first solenoid valve 10 on the left side and the second solenoid valve 28 on the right side to open. At this time, the cooling water enters the inside of the first filter cartridge 21 through the first connecting pipe 6 on the left side for filtration. At this time, the PLC controller controls the two-way booster pump 13 to start, so as to spray the filtered cooling water into the inside of the second filter cartridge 21 after pressurization, wash the impurities inside the second filter cartridge 21, and pass through the filter cartridge 21, and flow into the inside of the third connecting pipe 9 through the second solenoid valve 28 on the right side, and enter the inside of the second filter cartridge 3 for the next step of processing; and after a period of time (the period of time can be 5 to 10 minutes), at this time, the PLC controller controls the first solenoid valve 10 on the left side and the second solenoid valve 28 on the right side to close, and opens the first solenoid valve 10 on the right side and the second solenoid valve 28 on the left side. At this time, the cooling water enters the inside of the second filter cartridge 21 through the first connecting pipe 6 on the right side for filtration. At this time, the PLC controller controls the two-way booster pump 13 to start in reverse, so as to spray the filtered cooling water into the inside of the first filter cartridge 21 after pressurization, wash the impurities inside the first filter cartridge 21, so that the two filter cartridges 21 are alternately in the "filtration state" and the "backwashing state", so that the filter can be automatically cleaned without stopping the machine, improving the system continuity. At the same time, the two filter cartridges 21 alternately undertake the filtration task, avoiding the single filter screen from being continuously impacted by water flow and rubbed by impurities for a long time, so as to extend the service life of the filter cartridge 21. At the same time, the two-way booster pump 13 sucks and reversely sucks the filtered cooling water to form a sputtering effect, increasing the pressure of the water impact, thereby improving the cleaning effect and the overall practicability of the device.

[0020] Please refer to Figures 3 to 8, the rotating assembly includes a connecting plate 14 fixedly connected to the inner side of the second filter cylinder 3, and the connecting plate 14 is fixedly connected to the second cylinder 11. A connecting block 17 is arranged inside the second cylinder 11. A rotating shaft 18 is rotatably connected to the inner side of the connecting block 17. Both ends of the rotating shaft 18 respectively penetrate to the outside of the connecting block 17 and are fixedly connected with a connecting seat 19. A fixing plate 20 is fixedly connected to the bottom of the two connecting seats 19, and the fixing plate 20 is fixedly connected to the filter cylinder 21; the rotating assembly further includes two first driving motors 15 installed on the top of the connecting plate 14. The output ends of the two first driving motors 15 respectively penetrate to the bottom of the connecting plate 14 and are fixedly connected with a rotating rod 16, and the bottom of the rotating rod 16 is fixedly connected to the connecting block 17; the up-and-down shaking mechanism includes a bevel gear 24 fixedly connected to one end of the rotating shaft 18. A bevel gear ring 23 is fixedly connected to the bottom of the second cylinder 11. A torsion spring 22 is installed between the connecting block 17 and the connecting seat 19; multiple sections of helical teeth are arranged at the bottom of the bevel gear ring 23, and the multiple sections of helical teeth are intermittently distributed around the bottom of the bevel gear ring 23. Each section of helical teeth is meshed with the bevel gear 24; The first driving motor 15 is controlled by the PLC controller, and the first driving motor 15 can be controlled to start intermittently. When the PLC controller controls the left first solenoid valve 10 and the right second solenoid valve 28 to open, at this time the PLC controller controls the second first driving motor 15 to start simultaneously, so as to drive the second rotating rod 16 to rotate, thereby driving the second connecting block 17 to rotate, so that the second filter cylinder 21 can rotate. When the water flow backwashes the second filter cylinder 21, the second filter cylinder 21 can rotate, so that different parts of it can take turns to contact the water flow, so as to comprehensively clean the inside of the second filter cylinder 21. At the same time, the rotation will increase the speed of impurity shedding inside the second filter cylinder 21, and at the same time, the centrifugal force is used to assist the water flow to peel off the attachments, improving the backwashing effect; When the second first drive motor 15 starts to drive the second filter cartridge 21 to rotate, when the second bevel gear 24 rotates to contact the helical teeth at the top of the second bevel gear ring 23, under the action of the helical teeth at the top of the second bevel gear ring 23, the second rotating shaft 18 is driven to rotate, thereby driving the second connecting seat 19 to rotate, so that the second filter cartridge 21 can rotate. And when the second rotating shaft 18 rotates to the point where the helical teeth at the top of the second bevel gear ring 23 are disengaged from the second bevel gear 24, at this time the second bevel gear ring 23 rotates to the maximum position. At this time, the second rotating shaft 18 continues to rotate. At this time, under the action of the second torsion spring 22, the second rotating shaft 18 is pushed to reset, thereby driving the second filter cartridge 21 to reset. In this way, it is realized that while the second filter cartridge 21 can rotate for reverse flushing, the second filter cartridge 21 can swing up and down synchronously, cooperating with the water flow scouring from the outside to the inside, so as to break the adhesion between the impurities and the filter screen. Especially for sticky impurities such as flocs, colloids or fine particles, vibration can make them loosen and fall off from the filter holes, significantly improving the backwashing effect. The up and down swing causes the direction and angle of the backwashing water flow to change periodically, forming a complex turbulent flow field. The turbulence can enhance the scouring force of the water flow on the filter screen, especially having a stronger cleaning ability for the blockages inside the filter holes; When the second filter cartridge 21 can rotate, the first filter cartridge 21 rotates synchronously. At this time, as the water to be filtered enters from the top of the second filter cartridge 21, the entire filter surface passes through the water flow in turn, ensuring that each mesh hole can participate in the filtration evenly, avoiding the accumulation of impurities in "dead corners", thereby increasing the effective filtration area per unit time. Rotating the first filter cartridge 21 can disperse the wear by making each part take turns to contact the water flow and impurities, making the overall wear more uniform and reducing the replacement cost, so as to improve the filtration efficiency and reduce the operation and maintenance cost; During the rotation of the first filter cartridge 21, in cooperation with the water flow entering from the top, centrifugal force is generated so that the impurities filtered by the first filter cartridge 21 can be thrown from the filter screen of the first filter cartridge 21 to the bottom, so as to avoid the continuous filtration of the first filter cartridge 21 when filtering cooling water; During the rotation of the first filter cartridge 21, in cooperation with the water flow entering from the top, when the first filter cartridge 21 rotates, under the action of the helical teeth at the top of the first bevel gear ring 23, the first filter cartridge 21 can be driven to swing up and down. Thus, it is realized that the first filter cartridge 21 can swing up and down during filtration, so as to apply reciprocating vibration or displacement to the filter screen through mechanical forces such as the pushing and meshing of the helical teeth, forming an effect similar to "rotary scrubbing", thereby enhancing the impurity stripping ability and reducing the residue of impurities on the filter screen, so as to further improve the filtration effect of the filter screen.

[0021] Please refer to Figures 5 to 10, the impurity deposition mechanism includes a first partition plate 29 and a fourth partition plate 32 fixedly connected to the inner side of the mud storage cylinder 7. A second partition plate 30 and a third partition plate 31 are slidably connected to the inner side of the mud storage cylinder 7. The bottom of the fourth partition plate 32 is fixedly connected with an installation bin 33. A hydraulic cylinder 34 is installed inside the installation bin 33. The output end of the hydraulic cylinder 34 penetrates through the top of the fourth partition plate 32 and is fixedly connected with a driving rod 35, and both the second partition plate 30 and the third partition plate 31 are fixedly connected with the driving rod 35; coupling grooves 36 are formed inside the first partition plate 29, the second partition plate 30, the third partition plate 31 and the fourth partition plate 32. A coupling plate 25 is fixedly connected to the bottom of the first partition plate 29 and the third partition plate 31 and the top of the second partition plate 30 and the fourth partition plate 32. The size of the coupling plate 25 is larger than that of the coupling groove 36, and a sealing ring is arranged at the contact part of the coupling plate 25 and the coupling groove 36; The hydraulic cylinder 34 is controlled by a PLC controller, and the hydraulic cylinder 34 can be controlled to start intermittently. When the filter cylinder 21 filters the cooling water, the hydraulic cylinder 34 has two strokes. At this time, the PLC controller starts once at intervals of a period of time (the period of time can be 5-10 minutes). When the PLC controls to start the first stroke of the hydraulic cylinder 34 for the first time, the driving rod 35 moves downward at this time, so that the first partition plate 29 is separated from the second partition plate 30. At this time, the space above and below the first partition plate 29 is opened. At the same time, when the third partition plate 31 and the fourth partition plate 32 are in contact, the third partition plate 31 and the fourth partition plate 32 continue to move until the coupling plates 25 and the coupling grooves 36 inside the third partition plate 31 and the fourth partition plate 32 are mutually attached. At this time, the space above and below the third partition plate 31 is isolated. At this time, the impurities filtered inside the filter cylinder 21 can fall onto the top of the third partition plate 31, so as to carry out preliminary collection. When the PLC controls to start the second stroke of the hydraulic cylinder 34, the driving rod 35 moves upward at this time, so that the third partition plate 31 and the fourth partition plate 32 are separated, and the first partition plate 29 and the second partition plate 30 are attached, so that the space above and below the first partition plate 29 is closed, and the space above and below the third partition plate 31 is opened, so that the impurities on the top of the third partition plate 31 can fall to the bottom of the fourth partition plate 32. At the same time, since the bottom of the fourth partition plate 32 is completely isolated from the filter cylinder 21, the water flow channel is blocked, forming a temporary "collection bin", so that the impurities are temporarily stored on the top of the third partition plate 31, avoiding the impurities from directly falling to the bottom of the mud storage cylinder 7 or flowing back with the water flow. At the same time, after the water flow is blocked, the impurities are not affected by the water flow impact when falling, and can quickly and stably settle to the bottom of the mud storage cylinder 7, improving the sedimentation efficiency; A discharge valve is arranged at the bottom of the mud storage cylinder 7, and a collection cylinder can be arranged at the bottom of the discharge valve. The discharge valve is controlled by a PLC controller and can be controlled to start intermittently, so that the dirt inside the mud storage cylinder 7 can be automatically discharged into the collection cylinder for collection.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
