Description

Technical Field

[0001] This invention belongs to the field of sludge filtration technology, specifically relating to a sludge filtration device for use on CNC machine tools for bearing processing. Background Technology

[0002] During the operation of CNC machine tools for bearing processing, waste oil mixed with sludge and solid impurities is generated. Traditional sludge filtration devices mostly rely on a single filtration method to treat waste oil, mainly relying on filter screens to intercept sludge impurities to purify the oil. If the waste oil from machine tools is not filtered and purified in time, the impurities will continue to wear down the internal transmission and lubrication structures of the machine tool, affecting the stability of equipment operation and causing oil waste. Therefore, carrying out efficient filtration treatment of waste oil from machine tools has become a necessary process to ensure the normal operation of equipment and realize the recycling of oil.

[0003] Existing similar filtration structures only have a single-layer filtration stage, making it difficult to effectively trap fine impurities. Even after purification, the oil is still prone to causing oil circuit blockage and machine wear. Long-term high-load operation of the filter components will accelerate wear. At the same time, the integrated cavity structure cannot be disassembled, and it is difficult to clean and repair the internal filter components after they accumulate dirt. Overall maintenance is cumbersome, and the entire equipment needs to be disassembled when a local component fails, which further increases the operation and maintenance costs and affects the overall efficiency of the device. Therefore, there is a need for an oil sludge filtration device for CNC machine tools used in bearing processing. Summary of the Invention

[0004] The purpose of this invention is to provide a sludge filtration device for CNC machine tools used in bearing processing that has a simple structure and reasonable design in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A sludge filtration device for CNC bearing machining includes a housing.

The bottom inner side of the centrifuge tank is provided with a conical bottom surface surrounding the outside of the mounting flange. A plurality of drainage grooves are provided on the conical bottom surface. Drainage holes are provided on the conical bottom surface that correspond one-to-one with the drainage grooves and are interconnected with each other. The drainage holes are connected to the inner and outer sides of the centrifuge tank.

[0008] As a further optimization of the present invention, the filter chamber is mainly composed of a filter cylinder that is detachably fixed to the bottom of the centrifuge barrel. A partition plate is fixedly provided on the inner side of the filter cylinder, and a plurality of filter plates are fixedly provided on the inner side of the partition plate.

[0009] As a further optimization of the present invention, two of the slide rail blocks are fixedly connected to the outer bottom of the centrifuge tank, and the other two slide rail blocks are fixedly connected to the outer top of the filter cylinder. The locking assembly includes two locking blocks that are slidably sleeved on the outer sides of two corresponding slide rail blocks on the same side. Two slide bars that slide and cooperate with the slide rail blocks are fixedly connected to the inner side of each of the two locking blocks. Corresponding upper and lower slide bar grooves are opened at both ends of the opposite side of the two locking blocks. A slide bar is slidably arranged on the inner side of each pair of opposite slide bar grooves.

[0010] As a further optimization of the present invention, the ends of both sliding rods are fixedly connected to limiting plates, the limiting plates slide against the inner wall of the sliding rod grooves, and each end of the sliding rod groove facing the limiting plate is fixedly connected to a compression spring sleeved on the outside of the sliding rod. The end of the compression spring away from the end of the sliding rod groove is tightly abutted against the side of the limiting plate that connects with the sliding rod. The bottom of the upper locking block is fixedly connected to an elastic buckle, and the top of the lower locking block is provided with a slot that cooperates with the elastic buckle. The inner side of the slot is fixedly connected to a locking block that engages with the elastic buckle.

[0011] As a further optimization of the present invention, two sealing plates are fixedly connected to the inner side of the housing. The upper sealing plate is sealed and sleeved on the outer side of the filter cylinder. The second limiting ring is movable on the lower side of the upper sealing plate. The transmission shaft rotates through the lower sealing plate. A bellows sleeved on the outer side of the transmission shaft is fixedly connected between the top of the sealing ring and the bottom of the centrifuge tank, and between the bottom of the sealing ring and the lower sealing plate. A liquid level sensor is fixed to the inner side of the housing between the two sealing plates. The top of the housing of the liquid level sensor is tightly attached to the bottom of the upper sealing plate.

[0012] As a further optimization of the present invention, the drive assembly includes a drive motor fixedly disposed on the outside of the housing. The output end of the drive motor is rotatably connected to the housing and the bottom of the transmission shaft, and a synchronous gear is fixedly connected to both the output end of the drive motor and the bottom of the transmission shaft. A synchronous toothed belt that rotates on the bottom of the inner side of the housing meshes between the two synchronous gears. Both synchronous gears and the synchronous toothed belt are located on the lower side of the lower sealing plate.

[0013] As a further optimization of the present invention, the transmission shaft is mainly composed of a transmission rod rotatably connected to the bottom of the inner side of the housing. After the transmission rod passes through the centrifuge barrel, a top block that matches the mounting flange is fixedly connected to the top. Several sliding block grooves corresponding to the sliding blocks are opened on the outer side of the transmission rod.

The oil inlet pipe is slidably passed through the rear end of the cover and fixedly connected to a first limiting ring located inside the centrifuge barrel. Two support bases are fixedly connected to the bottom of the housing.

[0015] The beneficial effects of this invention are as follows: 1. In this invention, the device relies on the centrifuge barrel and liner inside the centrifuge chamber to complete the initial separation. The oil flows into the filtration chamber through the drain tank and drain hole, and then undergoes secondary filtration by the filter plate inside the filter cylinder. The two-layer structure works together to intercept impurities layer by layer. The two-stage filtration structure can effectively remove the sludge and fine impurities mixed in the oil, greatly improve the cleanliness of the oil, and ensure that the recovered oil can be reused in the machine tool. At the same time, it reduces the load on a single filtration structure and extends the service life of each filtration component.

[0016] 2. In this invention, the filter chamber and centrifuge chamber can be separated by means of a locking component, a slide block and a sliding structure. The compression spring, together with the elastic buckle and the slot, enables quick locking and unlocking. The filter cylinder can also slide smoothly away from the centrifuge chamber along the transmission rod. The separable combination structure allows the two chambers to be cleaned and maintained independently. The disassembly and assembly process is simple and convenient, without the need to disassemble the entire equipment, which reduces the difficulty of equipment maintenance and allows for targeted replacement of damaged parts.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] like Figures 1 to 4As shown, an oil sludge filtration device for a CNC machine tool used in bearing processing includes a housing 1. The housing 1 is used to house and protect the internal filtration structure. The housing 1 has a shell 101 as its main structure, which supports all components and forms a sealed cavity. Two sealing plates 7 are fixedly connected to the inner side of the shell 101. The sealing plates 7 are used to separate the cavity and achieve sealing and isolation of each area. A top cover 102 is rotatably connected to the top of the shell 101 via a hinge. The top cover 102 is used to close the top of the shell 101 to facilitate the maintenance of internal components. A rotating plate 103 is rotatably connected to the outer side of the shell 101 via a hinge. The rotating plate 103 is used for auxiliary protection and to cooperate with the cavity sealing. The bottom of the rotating plate 103 is located above the upper sealing plate 7. An oil outlet pipe 3 is connected to the rotating plate 103 on the same side. The oil outlet pipe 3 is used to discharge the pure oil after filtration. The oil outlet pipe 3 is located between the two sealing plates 7. An oil inlet pipe 2 extends through the top cover 102 and extends to the inside of the housing 101. The oil inlet pipe 2 is used to transport the machine tool muddy waste oil into the device. Two support bases 4 are fixedly connected to the bottom of the housing 101. The support bases 4 are used to support the entire device and ensure stable placement. A liquid level sensor 11 is fixed inside the housing 101 between the two sealing plates 7. The liquid level sensor 11 is used to monitor the liquid level inside the cavity in real time and send a real-time signal to the PLC controller to control the oil pumping mechanism to pump out the oil and prevent the oil from overflowing. The top of the housing of the liquid level sensor 11 is tightly attached to the bottom of the upper sealing plate 7.

[0021] like Figure 6 and Figure 7As shown, a centrifugal chamber 5 is rotatably disposed inside the housing 101. The centrifugal chamber 5 is used to perform preliminary separation of sludge and oil by relying on centrifugal force. A drive shaft 8 is fixedly disposed inside the centrifugal chamber 5 and rotatably connected to the bottom of the inner side of the housing 101. The drive shaft 8 is used to transmit power and drive the centrifugal chamber 5 to rotate as a whole. The centrifugal chamber 5 has a centrifugal bucket 501 rotatably disposed at the top of the inner side of the housing 101 as its main structure. The centrifugal bucket 501 is the main container for centrifugal separation. The top of the centrifugal bucket 501 is detachably disposed with a barrel by bolts. The lid 502 is used to seal the top of the centrifuge tank 501 to prevent oil splashing. Two symmetrically distributed positioning pins 503 are fixed to the top of the centrifuge tank 501. A detachable liner 504 is fitted inside the centrifuge tank 501. The positioning pins 503 are used to position and insert the liner 504, limiting its position. The liner 504 is used to adhere to the sludge and solid impurities separated by centrifugation. Two positioning plates 505 are fixed to the top of the liner 504, which engage with the positioning pins 503. The positioning plates 505 are used to cooperate with... Positioning pin 503 completes the installation and positioning of liner 504. A mounting flange 506, which mates with drive shaft 8, is detachably installed on the inner bottom of centrifuge tank 501. Mounting flange 506 is used to fix centrifuge tank 501 to drive shaft 8. A conical bottom surface 507 is formed on the inner bottom of centrifuge tank 501, surrounding the outside of mounting flange 506. Conical bottom surface 507 guides oil flow towards drain hole 509. Several drain grooves 508 are formed on conical bottom surface 507, used to collect oil and... The oil is guided to the drain hole 509. The conical bottom surface 507 has drain holes 509 that correspond one-to-one with and are interconnected with the drain trough 508. The drain hole 509 is used to guide the initially separated oil into the secondary filtration component. The drain hole 509 connects the inner and outer sides of the centrifuge barrel 501. The oil inlet pipe 2 slides through the rear end of the barrel cover 502 and is fixedly connected to the first limiting ring 510 located inside the centrifuge barrel 501. The first limiting ring 510 is used to limit the extension length of the oil inlet pipe 2 and prevent the oil inlet pipe 2 from coming out of the centrifuge chamber 5 during centrifugation.

[0022] like Figures 3 to 5 as well as Figures 7 to 9As shown, a drive assembly 13, which cooperates with the transmission shaft 8, is fixedly installed on the outer side of the housing 101. The drive assembly 13 provides power to drive the transmission shaft 8 and the centrifugal chamber 5 to rotate. The drive assembly 13 includes a drive motor 1301 fixedly installed on the outer side of the housing 101. The drive motor 1301 is used to output rotational power. In this invention, the model of the drive motor 1301 is Y100L2-4. Synchronous gears 1302 are fixedly connected to the output end of the drive motor 1301 after it rotates through the housing 101 and to the bottom of the transmission shaft 8. A synchronous toothed belt 1303, which rotates on the inner bottom of the housing 101, meshes between the two synchronous gears 1302. The synchronous gears 1302 cooperate with the synchronous toothed belt 1303 to achieve synchronous power transmission. The synchronous toothed belt 1303 is used to connect the two sets of synchronous gears 1302. The transmission shaft 8 transmits rotational power. The two synchronous gears 1302 and the synchronous toothed belt 1303 are located on the lower side of the lower sealing plate 7. The transmission shaft 8 is mainly composed of a transmission rod 801 rotatably connected to the bottom of the inner side of the housing 101. The transmission rod 801 serves as the main body of the transmission shaft 8, transmitting torque and allowing the components to slide. After the transmission rod 801 passes through the centrifuge tank 501, a top block 802 is fixedly connected to the top to fit the mounting flange 506. The top block 802 is used to tighten the mounting flange 506 and reinforce the connection between the transmission rod 801 and the centrifuge tank 501. Several slider grooves 803 are opened on the outer side of the transmission rod 801. The slider grooves 803 are used to cooperate with the sliding components to realize the sliding of the filter structure along the transmission rod 801. The length of the slider grooves 803 is equal to the distance between the two sealing plates 7. The transmission shaft 8 rotates through the lower sealing plate 7.

[0023] like Figure 4 , Figure 8 and Figure 9As shown, a filter chamber 6 is detachably installed at the bottom of the centrifuge chamber 5. The filter chamber 6 is used for secondary fine filtration of the oil to remove fine impurities. The filter chamber 6 has a filter cylinder 601 detachably fixed to the bottom of the centrifuge barrel 501 as its main structure. The filter cylinder 601 is the bearing chamber for secondary filtration. A partition plate 602 is fixedly installed on the inner side of the filter cylinder 601. The partition plate 602 is used to divide the internal space of the filter cylinder 601 and fix the filter plates 603. Several filter plates 603 are fixedly installed on the inner side of the partition plate 602. The filter plates 603 are used to intercept fine impurities and complete the secondary filtration of the oil. A sealing ring 605 is rotatably connected to the middle of the partition plate 602 and is slidably sleeved on the outside of the drive shaft 8. The sealing ring 605 is used to seal the rotating parts. To prevent oil leakage, the inner wall of the sealing ring 605 is fixedly connected with several sliding blocks 606. The sliding blocks 606 are used to engage with the slider groove 803, driving the filter chamber 6 to rotate synchronously. The bottom outer side of the filter cylinder 601 is fixedly connected with a second limiting ring 604, which is used to limit the upward movement range of the filter cylinder 601. The upper sealing plate 7 is sealed and sleeved on the outside of the filter cylinder 601. The second limiting ring 604 is movable on the lower side of the upper sealing plate 7. The top of the sealing ring 605 and the bottom of the centrifuge tank 501, as well as the bottom of the sealing ring 605 and the lower sealing plate 7, are both sealed and fixedly connected with a bellows 12 sleeved on the outside of the drive shaft 8. The bellows 12 is used to slide and expand with the components while maintaining a sealed state.

[0024] like Figure 3 , Figure 6 , Figure 8 , Figure 10 as well as Figure 11As shown, both the filter chamber 6 and the centrifuge chamber 5 are fixedly connected to two symmetrically arranged slide rail blocks 9. The slide rail blocks 9 provide sliding tracks for the locking block 1001. The slide rail blocks 9 on the centrifuge chamber 5 correspond to the slide rail blocks 9 on the filter chamber 6. Two slide rail blocks 9 are fixedly connected to the bottom outer side of the centrifuge barrel 501, and the other two slide rail blocks 9 are fixedly connected to the top outer side of the filter barrel 601. Each pair of corresponding slide rail blocks 9 can be detachably provided with a locking assembly 10 to cooperate with the closing of the centrifuge chamber 5 and the filter chamber 6. The locking assembly 10 is used to lock the centrifuge chamber 5 and the filter chamber 6 to prevent separation during operation. The locking assembly 10 includes two slidingly sleeved on the same... Two locking blocks 1001 are located on the outer sides of two corresponding slide rail blocks 9. Two slide bars 1002 are fixedly connected to the inner sides of each locking block 1001, which slide in cooperation with the slide rail block 9. The slide bars 1002 are used to conform to the slide rail block 9, ensuring smooth sliding of the locking blocks 1001. Corresponding upper and lower slide rod grooves 1003 are provided at both ends of each opposite side of the two locking blocks 1001. A slide rod 1004 is slidably arranged on the inner side of each pair of opposite slide rod grooves 1003. The slide rod grooves 1003 are used to accommodate the slide rods 1004 and limit their sliding trajectory. The slide rods 1004 are used to connect the two locking blocks 1001 on both sides, transmitting displacement. The ends of the two slide rods 1004... Each component is fixedly connected to a limiting plate 1005, which blocks the sliding rod 1004 and prevents it from disengaging from the sliding rod groove 1003. The limiting plate 1005 slides against the inner wall of the sliding rod groove 1003. Each end of the sliding rod groove 1003 facing the limiting plate 1005 is fixedly connected to a compression spring 1006 sleeved on the outside of the sliding rod 1004. The compression spring 1006 is always in a contracted state to provide elastic force and maintain the locking state of the locking block 1001. The end of the compression spring 1006 away from the end of the sliding rod groove 1003 is tightly abutted against the side of the limiting plate 1005 that is connected to the sliding rod 1004. The upper locking block 1001... The bottom of 01 is fixedly connected with an elastic buckle 1007. The top of the lower locking block 1001 is provided with a slot 1008 that cooperates with the elastic buckle 1007. The locking block 1001 is used to cooperate with the elastic buckle 1007 and the slot 1008 to achieve overall locking. The elastic buckle 1007 is used to cooperate with the slot 1008 to achieve the locking and fixing of the upper and lower locking blocks 1001. The slot 1008 is used to accommodate the elastic buckle 1007 and complete the locking cooperation between the components. The inner side of the slot 1008 is fixedly connected with a locking block 1009 that engages with the elastic buckle 1007. The locking block 1009 is used to form a lock with the elastic buckle 1007 in the slot 1008.

[0025] It should be noted that when the oil sludge filtration device on the bearing processing CNC machine tool is working, the drive assembly 13 is started in advance before oil is introduced. The drive motor 1301 drives the synchronous gear 1302 at its output end to rotate. Through the transmission of the synchronous tooth belt 1303, the synchronous gear 1302 at the bottom of the drive shaft 8 rotates synchronously, thereby causing the drive shaft 8 to drive the centrifugal chamber 5 to rotate inside the housing 101 of the device housing 1. Then, the oil sludge-containing waste oil generated by the machine tool is sent into the centrifugal barrel 501 through the oil inlet pipe 2 by the liquid pump. The first limiting ring 510 at the end of the oil inlet pipe 2 can prevent the oil from directly impacting the inner liner 504 and avoid oil sludge splashing affecting the centrifugation effect. During the high-speed rotation of the centrifugal chamber 5, most of the oil sludge and impurities are thrown to the barrel wall and adhere to the inner liner 504 under the action of centrifugal force, while the oil enters the filter chamber 6 below through the drain groove 508 and drain hole 509 on the conical bottom surface 507 at the bottom of the centrifugal barrel 501 under the action of centrifugal force, completing the initial centrifugal solid-liquid separation.

[0026] After initial filtration, the oil enters the filter cylinder 601 and undergoes secondary filtration through multiple filter plates 603 on the partition plate 602 to further remove residual fine impurities. The sealing ring 605 in the middle of the inner side of the filter cylinder 601 slides with the slider groove 803 on the outer side of the transmission rod 801 through the sliding block 606, which ensures the synchronous rotation of the filter chamber 6 and the transmission shaft 8, and can slide along the axial direction of the transmission rod 801 when disassembly is required. After filtration, the oil finally flows into the cavity between the two sealing plates 7. The liquid level sensor 11 can monitor the oil level in the cavity in real time to prevent oil overflow. When the oil reaches a certain level, the pure oil is discharged through the oil outlet pipe 3 on the outer side of the housing 101 and returned to the machine tool oil circuit for recycling.

[0027] When filtration is complete and the device needs cleaning, first open the top cover 102 on the top of the housing 101, then remove the barrel cover 502. Since the inner liner 504 is engaged with the positioning pin 503 on the centrifuge barrel 501 through the positioning plate 505 on the top, the inner liner 504 can be directly removed from the centrifuge barrel 501. You can either directly replace the inner liner 504 with a new one, or scrape off and clean the sludge attached to the inner liner 504 without having to disassemble the centrifuge barrel 501 body in a complicated manner. To clean the filter chamber 6, the locking assembly 10 can be operated to slide the two locking blocks 1001 along the slide rail block 9 to both sides. The sliding rod 1004 slides in the slide rod groove 1003 and compresses the compression spring 1006, causing the elastic buckle 1007 at the bottom of the upper locking block 1001 to disengage from the slot 1008 at the top of the lower locking block 1001, thus releasing the lock between the centrifuge chamber 5 and the filter chamber 6. Then, the filter cylinder 601 can be slid down along the slider groove 803 on the outside of the transmission rod 801 to separate the filter chamber 6 from the centrifuge chamber 5. At this time, the bellows 12 can extend and retract synchronously with the sliding of the filter cylinder 601, which does not affect the separation operation and can ensure the seal between the filter chamber 6 and the transmission shaft 8 in the working state. After separation, the filter cylinder 601 can be opened to clean or replace the inner filter plate 603. The entire disassembly process does not require additional tools and is convenient and efficient. After cleaning, the components are reset in reverse order and can be put back into use. The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
