Description

Technical Field

[0001] This invention relates to the field of liquid purification and separation devices, specifically a cyclone magnetic composite filtration and separation device for industrial processing liquids. Background Technology

[0002] Industrial processing fluids (such as metal cutting fluids and grinding fluids) will mix with various solid impurities such as iron filings and sand during the recycling process. These impurities not only accelerate equipment wear and block pipelines, but also reduce the quality of the processed surface. Therefore, the processing fluids must be effectively purified. Currently, commonly used purification methods include cyclone separation, filtration separation, and magnetic adsorption. Cyclone separation uses centrifugal force to make heavy impurities settle along the wall of the container. It can handle large volumes but is difficult to remove fine iron filings and cannot selectively separate iron filings from sand and gravel. Filtration separation relies on the filter medium to intercept impurities. It has high precision but the filter screen is easy to clog and requires frequent shutdowns for cleaning or replacement of the filter media. Magnetic adsorption has high selectivity for ferromagnetic particles, but it cannot remove non-magnetic impurities such as sand and gravel at the same time. Moreover, the process of cleaning the adsorbed iron filings often requires interrupting the operation or relying on complex mechanical scraping structures. Therefore, there is an urgent need for a composite filtration and separation device that can efficiently separate iron filings and sand in the same unit, clean iron filings without stopping the machine, and has a compact and reliable structure. Summary of the Invention

One side of the sealing rotating cylinder has an opening that matches the opening of the magnetic suction groove. By rotating the sealing rotating cylinder 180 degrees, the opening of the magnetic suction groove can be sealed. A chip removal pipe is connected to the lowest point of the bottom of the magnetic suction groove. An electric valve is installed on the chip removal pipe. A through hole is opened on the side wall above the sealing rotating cylinder and away from its opening. A filter cartridge is detachably installed inside the central cylinder. A detachable cover plate is provided on the top of the filter cartridge. An ultrasonic transducer extending into the filter cartridge is fixedly installed at the center of the cover plate. A backwashing assembly is connected to the central cylinder.

The upper wall of the impeller is provided with a plurality of magnets (first type). A rotating ring is rotatably arranged on the outer side of the upper part of the tank. The lower wall of the rotating ring is provided with a plurality of magnets (second type) corresponding to the magnets (first type).

[0008] Preferably, the backwashing assembly includes a storage tank, a piston is slidably disposed inside the storage tank, a linear cylinder for pushing and pulling the piston is fixedly disposed on the storage tank, and two connecting pipes are provided on both sides of the end of the storage tank, one of which is connected to the clean liquid discharge pipe, and the other connecting pipe is connected to an electric valve.

[0009] Preferably, an inlet ring pipe is fixedly installed on the upper outer wall of the tank, and each inlet is connected to the inlet ring pipe. A main inlet pipe tangential to the inlet ring pipe is provided on the inlet ring pipe.

[0010] Preferably, a rotary cylinder is fixedly installed on the outer side of one end of the magnetic suction groove, and the power output end of the rotary cylinder passes through the side wall of the magnetic suction groove and is connected to the sealing rotary cylinder.

[0011] Preferably, a recycling ring pipe is fixedly installed at the bottom of the tank, and each of the chip discharge pipes is connected to the recycling ring pipe, and the recycling ring pipe is connected to a main chip discharge pipe.

[0012] Preferably, a first protrusion is fixedly provided on the inner side of the bottom of the central cylinder, and a second protrusion is fixedly provided on the lower surface of the cover plate. The upper and lower ends of the filter cylinder are respectively inserted into the first protrusion and the second protrusion.

[0013] This invention provides a cyclone magnetic composite filtration and separation device for industrial liquid processing, which has the following beneficial effects: 1. When the processing liquid rotates inside the tank, larger particles such as iron filings and sand are thrown towards the inner wall of the tank and the conical section under the action of centrifugal force. By setting up multiple magnetic suction grooves and setting up an electromagnet rod in each magnetic suction groove to attract iron filings, while non-magnetic impurities such as sand continue to sink along the wall, the iron filings and sand are gathered together on the inner wall of the conical section by the swirling flow. Then, the iron filings are selectively captured by fixed-point magnetic attraction, which ensures the separate treatment of the two types of impurities, iron filings and sand, and improves the separation accuracy. 2. A 180-degree rotatable sealing drum is installed inside the magnetic suction tank, and the energization of the electromagnet and the opening and closing of the electric valve of the chip removal pipe are controlled to clean a single magnetic suction tank without interrupting the main vortex separation process. Multiple magnetic suction tanks are distributed in a circumferential ring array along the conical section. When a magnetic suction tank enters the chip removal state, the other magnetic suction tanks are still in the normal adsorption state, thus ensuring that the entire device maintains the ability to continuously capture iron chips during the chip removal process. It is suitable for industrial applications with large processing liquid flow and high iron chip content. Furthermore, when the sealing drum rotates to the sealing position, its upper through hole automatically introduces the processing liquid in the tank into the magnetic suction tank to flush the electromagnet and the inner wall of the tank. There is no need to set up a separate flushing pipeline, which further simplifies the chip removal operation. 3. The processing liquid, after preliminary purification by cyclone and magnetic attraction, undergoes secondary precision filtration through the filter cartridge in the central cylinder to further improve the filtration and separation quality. The filtered processing liquid can be pre-stored in the storage tank as a backwash medium. The straight cylinder with piston can deliver the backwash medium to the central cylinder. Combined with the cavitation effect of the ultrasonic transducer, the filter cartridge is backwashed, achieving efficient cleaning without disassembling the filter cartridge. 4. Optionally, an impeller can be installed inside the tank. When the flow rate of the processed liquid is low and the natural swirling intensity is insufficient, the motor can be started to drive the impeller to rotate, actively increasing the tangential velocity of the liquid inside the tank, thereby maintaining a high-efficiency swirling separation effect. Non-contact torque transmission is achieved through a magnetic coupling, which not only ensures the sealing of the tank but also makes the drive component external for easy maintenance.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] Please see Figures 1 to 10 This invention provides a technical solution: a cyclone magnetic composite filtration and separation device for industrial processing liquids, comprising: Tank 1, with a conical section 2 at the bottom and multiple tangentially arranged liquid inlets 3 on the upper side wall of tank 1, so that the processing liquid can rotate along the circumferential direction of tank 1 when it enters the tank 1. A central cylinder 4 is provided at the center of the upper wall of tank 1, and a clean liquid drain pipe 5 is connected to the side wall of the outer side of tank 1. A sand discharge pipe 6 is connected to the lowest point of the conical section 2. The magnetic suction grooves 7, numbered four to six, are arranged in a ring array on the side wall of the conical section 2. The magnetic suction grooves 7 are connected to the interior of the conical section 2 through an opening on one side. An electromagnet rod 8 is fixedly installed at the center of the magnetic suction groove 7. When the electromagnet rod 8 is energized, it attracts iron filings in the processing liquid. The connection between the magnetic suction groove 7 and the inner wall of the conical section 2 is provided with a rounded chamfer to reduce turbulence on the processing liquid. A sealing drum 9 is rotatably installed inside the magnetic suction groove 7. One side of the sealing drum 9 has an opening that matches the opening of the magnetic suction groove 7. When the openings of the two are in the same direction, the magnetic suction groove 7 is connected to the inside of the tank 1. By rotating the sealing drum 9 180 degrees, the opening of the magnetic suction groove 7 can be sealed. The lowest point of the bottom of the magnetic suction groove 7 is connected to a chip removal pipe 10. An electric valve 11 is installed on the chip removal pipe 10. A through hole 12 is opened on the side wall above the sealing drum 9 and away from its opening. When the sealing drum 9 seals the opening of the magnetic suction groove 7, it stops energizing the electromagnet rod 8. At this time, the electromagnet rod 8 does not generate magnetism, and the iron filings fall off due to gravity and liquid flushing. Opening the electric valve 11 allows some of the processing liquid in the magnetic suction groove 7, along with the iron filings, to be discharged through the chip removal pipe 10, thus realizing the discharge of iron filings. At the same time, the processing liquid inside the tank 1 can flow into the magnetic suction groove 7 through the through hole 12, thus rinsing the inside of the magnetic suction groove 7 and the electromagnet rod 8. The filter cartridge 13 is detachably installed inside the central cylinder 4 for further filtration of the processed liquid after cyclone separation. The top of the filter cartridge 13 is provided with a detachable cover plate 14. The filter cartridge 13 can be removed by opening the cover plate 14. An ultrasonic transducer 15 extending into the filter cartridge 13 is fixedly installed at the center of the cover plate 14. The ultrasonic transducer 15 is connected to a matching ultrasonic generator. The central cylinder 4 is connected to a backwashing assembly, which can realize backwashing of the filter cartridge 13. The ultrasonic cavitation effect generated by the ultrasonic transducer 15 helps fine particles to fall off the surface of the filter cartridge 13, improving the backwashing efficiency.

[0018] As an embodiment of the present invention, an impeller 16 is rotatably arranged on the inner side of the upper part of the tank body 1 and near the liquid inlet 3. When processing low-flow processing liquid, in order to increase the rotation speed of the liquid in the tank body 1, the impeller 16 can be selectively arranged in the tank body 1. The upper wall of the impeller 16 is provided with a plurality of magnets 17. The outer side of the upper part of the tank body 1 is rotatably arranged with a rotating ring 18. The lower wall of the rotating ring 18 is provided with a plurality of magnets 19 corresponding to the magnets 17. The magnets 17 on the impeller 16 and the magnets 19 on the rotating ring 18 form a magnetic coupling, which can improve the sealing of the tank body 1 while transmitting torque. At the same time, it also realizes that the power output part is located on the outside of the tank body 1, which is convenient for inspection and maintenance.

[0019] As an embodiment of the present invention, a detachable protective cover 20 is provided on the upper wall of the tank body 1, and the rotating ring 18 is placed inside the protective cover 20 to protect the rotating ring 18. A motor 21 is fixedly provided on the protective cover 20, and a gear 22 is provided on the driving end of the motor 21. A gear ring 23 that can mesh with the gear 22 is provided on the rotating ring 18, and the rotating ring 18 is driven to rotate by the motor 21.

[0020] As an embodiment of the present invention, the bottom and sidewalls of magnet 17 are covered with a magnetic shielding layer 24 to prevent iron filings in the processing liquid from being magnetically attracted by magnet 17. Impeller 16 is rotatably mounted on the central cylinder 4, and rotary seals 25 are provided at both the inner and outer edges of impeller 16 to prevent impurities from entering the gap between impeller 16 and the upper wall of tank 1 along with the processing liquid.

[0021] As an embodiment of the present invention, the backwashing assembly includes a storage tank 26, a piston 27 is slidably disposed inside the storage tank 26, and a straight-line cylinder 28 for pushing and pulling the piston 27 is fixedly disposed on the storage tank 26. Two connecting pipes 29 are provided on both sides of the end of the storage tank 26. One connecting pipe is connected to the clean liquid discharge pipe 5, and the other connecting pipe is connected to an electric valve 30. When the processing liquid is filtered, it will be discharged through the clean liquid discharge pipe 5. At this time, the straight-line cylinder 28 is activated to pull the piston 27 to draw part of the filtered processing liquid into the storage tank 26 for storage. When backwashing is required, the electric valve 30 is closed, and then the straight-line cylinder 28 is activated to push the piston 27 to move, pushing the processing liquid stored in the storage tank 26 into the central cylinder 4 to achieve backwashing of the internal filter cylinder 13.

[0022] As an embodiment of the present invention, an inlet ring pipe 31 is fixedly provided on the upper outer wall of the tank body 1. Each inlet 3 is connected to the inlet ring pipe 31. Through multiple inlets 3, the processing liquid can enter the tank body 1 more evenly, realizing the dispersion effect of the processing liquid. A main inlet pipe 32 is provided on the inlet ring pipe 31 and is tangent to it. When the liquid in the main inlet pipe 32 is discharged into the inlet ring pipe 31, it can rotate, thereby increasing the flow rate of the processing liquid in the inlet 3.

[0023] As an embodiment of the present invention, a rotary cylinder 33 is fixedly provided on the outer side of one end of the magnetic suction groove 7. The power output end of the rotary cylinder 33 passes through the side wall of the magnetic suction groove 7 and is connected to the sealing rotating cylinder 9. The rotary cylinder 33 controls the sealing rotating cylinder 9 to rotate 180 degrees.

[0024] As an embodiment of the present invention, a recovery ring pipe 34 is fixedly provided at the bottom of the tank body 1, and each chip discharge pipe 10 is connected to the recovery ring pipe 34. The recovery ring pipe 34 is connected to the chip discharge main pipe 35 to realize the unified collection of the molten iron mixture discharged from each magnetic suction tank 7.

[0025] As an embodiment of the present invention, a first protrusion 36 is fixedly provided on the inner side of the bottom of the central cylinder 4, and a second protrusion 37 is fixedly provided on the lower surface of the cover plate 14. The upper and lower ends of the filter cylinder 13 are respectively inserted into the first protrusion 36 and the second protrusion 37 to realize the insertion of the filter cylinder 13, so that the filter cylinder 13 can be removed by opening the cover plate 14, which facilitates the subsequent maintenance of the filter cylinder 13.

[0026] The working principle and usage process of this invention are as follows: During use, the processing liquid enters the inlet ring pipe 31 through the main inlet pipe 32. Since the two are tangentially connected, the processing liquid can rotate and flow within the inlet ring pipe 31. The rotating processing liquid enters the tank 1 through each inlet 3. Because the inlets 3 are also tangentially arranged, the processing liquid can rotate upon entering the tank 1. This rotation within the tank 1 achieves vortex separation, allowing larger particles of impurities to move towards the side wall of the tank 1. When the impurities move downwards along the side wall of the tank 1 to the conical section 2, the electromagnet rod 8 connected to the power supply can attract iron filings from the impurities. Impurities such as sand and gravel that cannot be attracted by the electromagnet rod 8 will continue to move downwards until they are discharged through the sand discharge pipe 6, thus achieving the separation of iron filings and sand / gravel. When it is necessary to clean the iron filings on the electromagnet rod 8, the rotating cylinder 33 on the magnetic suction groove 7 is activated. The rotating cylinder 33 drives the sealing drum 9 to rotate (e.g., ...). Figure 7(As shown) The opening of the magnetic suction groove 7 is closed by rotating the sealing drum 9 180 degrees, the electric valve 11 is opened and the power to the electromagnet rod 8 is cut off. At this time, the iron filings in the magnetic suction groove 7 and the processing liquid stored inside are discharged into the recovery ring pipe 34 through the chip discharge pipe 10. At the same time, a small amount of processing liquid in the tank 1 can enter the magnetic suction groove 7 through the through hole 12 on the upper side wall of the sealing drum 9 to rinse the magnetic suction rod. The cleaning time can be controlled by controlling the opening time of the electric valve 11. After cleaning, the electric valve 11 is closed to control the sealing. After the rotating drum 9 is reset and the electromagnet rod 8 is energized again, it can perform adsorption operations. Because four to six magnetic adsorption slots 7 are provided, iron filings can be removed alternately. When one magnetic adsorption slot 7 is being cleaned, the others can continue to perform magnetic adsorption. The molten iron mixture discharged from each magnetic adsorption slot 7 is collected centrally through the recovery ring pipe 34 and finally discharged through the main chip removal pipe 35. The processing liquid in the tank 1, after initial separation, flows into the central cylinder 4, where it undergoes further precision filtration through the filter cylinder 13 to reduce... Fine particulate impurities in the processing liquid can be removed by opening the cover plate 14, facilitating regular replacement and maintenance of the filter cartridge 13. The processing liquid, after secondary filtration by the filter cartridge 13, can be discharged through the clean liquid drain pipe 5, the storage tank 26, and the electric valve 20. When the processing liquid flows into the storage tank 26, a portion of the processing liquid can be drawn into the storage tank 26 for storage by pulling the piston 27 through the straight-line cylinder 28. After the filtration operation is completed, the filter cartridge 13 can be backwashed. First, the electric valve 20 is closed, and then the straight-line cylinder 28 pulls the piston 27. The cylinder 28 pushes the piston 27 to move, and the piston 27 pushes the processing liquid stored in the storage tank 26 into the central cylinder 4 as a backwashing medium to achieve backwashing of the filter cylinder 13. During backwashing, the equipment is in a stopped filtration state, so the impurities filtered by the filter cylinder 13 can settle downward in the tank 1 and finally be discharged through the sand discharge pipe 6. During the backwashing of the filter cylinder 13, the ultrasonic transducer 15 can also induce the cavitation effect of liquid molecules, thereby improving the backwashing efficiency of the filter cylinder 13 and ensuring the filtration effect of the filter cylinder 13. In addition, the impeller 16 can be selectively installed according to the flow rate of the processed liquid and the requirements of the filtration effect. The rotating ring 18 can be driven to rotate by starting the motor 21. The magnet 19 below the rotating ring 18 and the magnet 17 on the impeller 16 form a magnetic coupling function. Therefore, the rotation of the rotating ring 18 can drive the impeller 16 to rotate. The rotation of the impeller 16 can agitate the processed liquid entering the tank 1, increase the rotation speed of the processed liquid in the tank 1, and obtain greater centrifugal force to improve the cyclone separation effect. When the filtration flow rate is low, the impeller 16 can also actively increase the rotation speed of the processed liquid in the tank 1 to ensure that the high efficiency of cyclone separation effect can still be maintained under low flow conditions.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
