Description

Technical Field

[0001] This invention relates to the field of cutting fluid treatment technology, specifically to an automated separation and treatment system and process for filter residue from machine tool cutting fluid. Background Technology

[0002] During metal cutting processes, machine tools use specialized industrial fluids to achieve functions such as cooling the tool and workpiece, lubricating the cutting interface, cleaning chips, and providing rust protection. After being recycled for a period of time, these cutting fluids become unusable due to the contamination of large amounts of metal chips, microorganisms, oil, and chemical degradation products. The resulting waste fluid is known as cutting waste fluid.

[0003] The existing invention patent with publication number CN115179100B discloses a method for separating machine tool machining waste, comprising the following process: dispersing and breaking up the machine tool machining waste, and then placing it into a horizontally positioned rotating container. The upper end of the rotating container is open outward, and at least one filter structure is provided on the rotating container. After the machine tool machining waste is placed into the rotating container, the rotating container rotates at high speed, causing the cutting fluid in the machine tool machining waste to be thrown out through the filter structure to the bottom of the rotating container. The machine tool machining waste is then thrown out from the upper end of the rotating container, realizing the separation of machine tool machining waste and cutting fluid. This invention utilizes the centrifugal force of high-speed rotation to achieve solid-liquid separation of machine tool machining waste and cutting fluid. Compared with the traditional method of separation using a filter screen or filter barrel relying on the downward permeation of cutting fluid, it has higher efficiency and better effect. Compared with the separation method using negative pressure adsorption, it is easier to implement and has a lower implementation cost.

[0004] Based on the aforementioned existing technologies, the current method of filtering cutting fluid through a screen is generally used to achieve solid-liquid separation. In order to prevent fine debris from passing through the screen, the pore size of the screen needs to be limited, which can easily lead to debris accumulation and affect the rate at which the cutting fluid passes through the screen. Furthermore, debris can get stuck in the mesh of the screen, requiring regular cleaning. However, the current method of backflushing cannot effectively clean the screen deeply, and there will still be stuck debris in the mesh. Summary of the Invention

The backflush unit, located inside the housing, uses airflow to clean the screen and guide the screened debris out. The vibration component, located inside the housing, uses the inertia generated by the vibration of the screen to separate the debris stuck in the mesh. A conveying assembly, located at the bottom of the housing, is used to convey the separated debris.

[0007] Preferably, the filter assembly further includes a drive shaft inserted into the top of the housing, with one end of the drive shaft connected to a drive motor. The drive motor is fixed to one side of the housing, and the motor's shaft is fixedly connected to the drive shaft. There are two drive shafts in total, and the two drive shafts have different sized toothed disc structures on both sides for driving the chain to rotate. A linkage component is provided at one end of each drive shaft. Preferably, the limiting plate includes a connecting plate that is rotatably connected to the housing via a bearing, and a movable plate is mounted on the inner side of the connecting plate via a bearing, and the movable plate and the connecting plate are rotatably connected, with the inner side of the movable plate being higher than the inner side of the connecting plate.

[0008] Preferably, the tensioning assembly includes a movable shaft movably mounted on both sides of the housing, and the movable shaft and the housing are slidably connected by a linear bearing. A limit shaft is inserted and installed at one end of the movable shaft, and a return spring is sleeved on the outer side of the movable shaft.

[0009] Preferably, the limiting frame includes a connecting plate whose top end is connected to the top of the outer shell, a connecting bridge is fixedly installed on the lower edge of the connecting plate, a partition is fixedly installed below the connecting bridge, and a limiting plate is fixedly installed between the partitions.

[0010] Preferably, the chain consists of four chains divided into two groups, inner and outer, located on the left and right sides of the outer shell respectively. The path of the chain is restricted by the guide shaft, the limiting plate, the tensioning component, and the transmission shaft. A circular structure with a notch at the upper angle is formed at the center of the limiting plate. The screen has two aperture sizes, with the large aperture screen installed between the outer chains and the small aperture screen installed between the inner chains.

[0011] Preferably, the backflush assembly includes an air compressor fixedly installed on the top of the housing, a split pipe fixedly installed at the exhaust port of the air compressor, a hose fixedly installed at the branch end of the split pipe, a backflush pipe connected to the bottom end of the hose, and a flat nozzle inserted into one side of the backflush pipe.

[0012] Preferably, the vibration assembly includes an eccentric shaft inserted into the housing, a transmission belt fitted onto the outer side of one end of the eccentric shaft, a drive motor connected to one end of the eccentric shaft, an installation plate fixedly installed inside the housing, a limit tube inserted into the surface of the installation plate, a movable pin movably installed at the bottom end of the limit tube, a buffer spring sleeved on the outer side of the movable pin, and a linkage assembly provided at one end of the eccentric shaft.

[0013] Preferably, the conveying assembly includes a conveying motor fixedly installed on the outside of the housing, an auger is embedded in the tubular structure at the bottom of the housing, a pulley is fixedly installed at one end of the central shaft of the auger, and a linkage belt is sleeved on the outside of the pulley.

[0014] Preferably, the separation mechanism further includes a linkage component, which includes a synchronous pulley sleeved on the outside of the corresponding shaft, and a synchronous belt sleeved on the outside of the synchronous pulley.

[0015] Preferably, it includes the following steps: S1: The cutting fluid is introduced into the filter assembly inside the housing through the diversion channel at the top of the housing to filter the cutting fluid. The debris falls into the tubular structure at the bottom of the housing under the guidance of the screen and is discharged. The liquid is discharged through the pipe structure at the front of the housing. S2: The high-pressure airflow generated by the back-blowing component back-blowing cleans the screen and guides the debris through the inclined structure at the bottom of the shell into the tubular structure at the bottom of the shell. S3: The vibrating component causes the screen to vibrate. During the upward movement of the screen, the movable pin pushes out the debris stuck in the screen mesh. At the same time, during the downward movement of the screen, the inertia causes the debris stuck in the screen mesh to detach from the screen. S4: Debris inside the tubular structure at the bottom of the housing is conveyed out of the housing via the conveying assembly; Beneficial effects This invention provides an automated system and process for separating and treating filter residue from machine tool cutting waste fluid. Compared with existing technologies, it has the following advantages: 1. Based on the automated separation and treatment system and process for machine tool cutting waste fluid, a staged filtration design is adopted. The outer large-aperture screen first intercepts large particles of debris, while the inner small-aperture screen filters out smaller particles, avoiding the obstruction of waste fluid flow caused by rapid clogging of a single-aperture screen. Simultaneously, a chain drives the two sets of screens to move continuously along similar paths, with the outer screen having a larger path size and wrapping around the inner screen. Debris moves with the screens to the rear vertical structure and falls in a concentrated manner. Combined with the high-pressure airflow guidance from the backflushing component, debris of different sizes falls precisely into the staggered tubular structure at the bottom, preventing debris accumulation on the screen surface. This method ensures the rate at which waste fluid passes through the screens, effectively improving the overall separation efficiency. 2. This automated separation and treatment system and process for filter residue from machine tool cutting waste fluid removes debris from the mesh through the dual action of a vibration component and a mechanical ejection structure: the eccentric shaft of the vibration component rotates, causing the screen to vibrate up and down repeatedly, using inertia to loosen and detach the debris stuck in the mesh; simultaneously, as the screen moves upward, the movable pin, precisely matched to the mesh spacing, smoothly passes through the mesh, ejecting stubborn debris. Furthermore, the buffer spring on the outside of the movable pin buffers the contact pressure, and the screen's moving speed is strictly limited to prevent misalignment or excessive collision between the movable pin and the mesh. This ensures effective debris removal while protecting the screen, thus completely restoring its passability and preventing a decrease in separation efficiency due to mesh blockage. 3. Based on the automated separation and treatment system and process for filter residue from machine tool cutting waste fluid, the backflushing component adopts a design with multiple backflushing pipes and flat nozzles, expanding the coverage of high-pressure airflow and increasing the airflow velocity, enabling targeted cleaning of surface debris in different areas of the screen. More importantly, the backflushing cleaning, screen vibration, and movable pin ejection create a synergistic effect: the backflushing airflow first loosens stubborn debris inside the mesh, reducing the adhesion between debris and the mesh wall; then, screen vibration further detaches the debris from the mesh; and the movable pin precisely ejects any remaining stubborn debris. The three working together achieve deep cleaning of the screen surface and the interior of the mesh, completely solving the problem that traditional backflushing can only remove surface debris and cannot handle debris stuck inside the mesh.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1 - Figure 11 The present invention provides a technical solution: The automated separation and treatment system and process for filter residue from machine tool cutting waste fluid includes a housing 1, and a separation mechanism 2 is installed inside the housing 1 for separating debris from the cutting fluid. The separation mechanism 2 includes: The filter assembly 21 includes a diversion channel 211 fixedly installed on the top of the housing 1. Guide shafts 212 and limiting discs 213 are interposed on both sides of the housing 1. Chains 214 are wound around the outer sides of the guide shafts 212 and limiting discs 213. A tensioning assembly 215 is provided at the front end of the housing 1. A screen 216 is fixedly installed between the chains 214. A limiting frame 217 is fixedly installed inside the housing 1. The filter assembly 21 also includes a drive shaft 218 interposed on the top of the housing 1, with one end of the drive shaft 218 connected to a drive motor 219. 19 is fixed to one side of the outer casing 1, and the rotating shaft of the drive motor 219 is fixedly connected to the drive shaft 218. There are two drive shafts 218, and different sized toothed disc structures are provided on both sides of the two drive shafts 218 to drive the chain 214 to rotate. A linkage component 25 is provided at one end of the drive shaft 218. The limiting plate 213 includes a connecting plate 2131 that is rotatably connected to the outer casing 1 through a bearing. A movable plate 2132 is mounted on the inner side of the connecting plate 2131 through a bearing, and the movable plate 2132 is rotatably connected to the connecting plate 2131. The inner side of disc 2132 is higher than the inner side of connecting disc 2131. The tensioning assembly 215 includes a movable shaft 2151 movably mounted on both sides of the outer casing 1, and the movable shaft 2151 and the outer casing 1 are slidably connected by a linear bearing. A limit shaft 2152 is inserted and installed at one end of the movable shaft 2151, and a return spring 2153 is sleeved on the outer side of the movable shaft 2151. The limit frame 217 includes a connecting plate 2171 whose top end is connected to the top of the outer casing 1. A connecting bridge 2172 is fixedly installed on the lower edge of the connecting plate 2171. The lower edge of the connecting bridge 2172... A partition 2173 is fixedly installed on the outer shell 1. A limit plate 2174 is fixedly installed between the partitions 2173. There are four chains 214 in total, divided into inner and outer groups, located on the left and right sides of the outer shell 1 respectively. The path of the chains 214 is restricted by the guide shaft 212, the limit plate 213, the tensioning component 215, and the drive shaft 218. A circular structure with a notch at the upper angle is formed at the center of the limit plate 213. The screen 216 has two aperture sizes. The large aperture screen 216 is installed between the outer chains 214, and the small aperture screen 216 is installed between the inner chains 214.

[0020] Specifically, the limiting frame 217 inside the outer casing 1 restricts the position of the cutting fluid entering the outer casing 1, ensuring that the cutting fluid can enter the circular structure formed by the screen 216 between the two limiting discs 213. The cutting fluid is screened by the two layers of screens 216 with different apertures. The liquid portion passing through the screen 216 will be guided by the inclined structure on the bottom front side of the outer casing 1 and discharged from the pipe structure at the bottom front side of the outer casing 1. The debris stays above the screen 216 and is driven by the drive motor 219 to rotate one of the drive shafts 218. The drive shafts 218 are linked by the linkage component 25, thereby being linked by the toothed structure at both ends of the drive shaft 218 and the chains 2 on both sides of the screen 216. 14 drives the screen 216 to move along a specific path. When the screen 216 moves to the rear bend, some debris falls directly and enters the two tubular structures at the bottom of the outer shell 1 under the guidance of the outer shell 1. The partition 2173 and the connecting plate 2171 are connected by the connecting bridge 2172, and a gap is reserved between the partition 2173 and the connecting plate 2171 to allow the screen 216 to move. The partition 2173 and the connecting plate 2171 restrict the position of the debris above the screen 216 and prevent the debris from falling from the two sides of the screen 216. The limiting plate 2174 is located between the inner and outer screens 216 and is used to prevent the debris intercepted by the inner small-diameter screen 216 from falling into the tubular structure used to collect large-particle debris.

[0021] The backflush assembly 22 is located inside the housing 1. It uses airflow to clean the screen 216 and guide the screened debris to be discharged. The backflush assembly 22 includes an air compressor 221 fixedly installed on the top of the housing 1. A split pipe 222 is fixedly installed at the exhaust port of the air compressor 221. A hose 223 is fixedly installed at the branch end of the split pipe 222. A backflush pipe 224 is connected to the bottom end of the hose 223. A flat nozzle 225 is inserted into one side of the backflush pipe 224.

[0022] Specifically, there are four backflush pipes 224, located on the inner side of the vertical section behind the screens 216 on both the inner and outer sides, and above the inclined structure above the two tubular structures at the bottom of the outer casing 1. The airflow generated by the air compressor 221 is directed through the split pipe 222 and into the corresponding backflush pipe 224 via the hose 223. Then, the airflow coverage width and airflow velocity are increased through the flat nozzle 225. While backflush cleaning the screens 216, the debris remaining above the inclined structure at the bottom of the outer casing 1 is guided into the corresponding pipe structure at the bottom of the outer casing 1.

[0023] Vibration component 23, located inside the housing 1, separates debris stuck in the mesh through the inertia generated by the vibration of the screen 216. Vibration component 23 includes an eccentric shaft 231 inserted inside the housing 1. A transmission belt 232 is fitted on the outer side of one end of the eccentric shaft 231. A drive motor 233 is connected to one end of the eccentric shaft 231. An installation plate 234 is fixedly installed inside the housing 1. A limit tube 235 is inserted on the surface of the installation plate 234. A movable pin 236 is movably installed at the bottom end of the limit tube 235. A buffer spring 237 is sleeved on the outer side of the movable pin 236. A linkage component 25 is provided at one end of the eccentric shaft 231.

[0024] Specifically, there are four eccentric shafts 231, arranged in two groups below the horizontal level at the bottom of the moving path of the inner and outer screens 216. Eccentric shafts 231 in the same group are linked by a linkage component 25 to ensure synchronous rotation. The two groups of eccentric shafts 231 are connected by a transmission belt 232, allowing the drive motor 233 to simultaneously drive all four eccentric shafts 231. The central shaft of each eccentric shaft 231 is rotatably connected to the outer casing 1. Eccentric wheels located below the chain 214 on both sides of each eccentric shaft 231 cause the chain 214 and the screen 216 to vibrate up and down when the eccentric shaft 231 rotates. The installation interval of the movable pins 236 matches the mesh spacing of the screen 216. When the screen 216 moves upward, the movable pins... 236 will pass through the screen 216, pushing the debris embedded in the mesh of the screen 216 downwards. The height of the movable pin 236 is changed within a certain range by the buffer spring 237 to prevent the movable pin 236 from damaging the screen 216. It can also limit the speed of the screen 216 when it moves upwards, preventing the debris stuck inside the screen 216 from falling upwards due to inertia. During the vibration of the screen 216, the debris stuck inside the mesh will fall downwards due to inertia and fall above the corresponding inclined structure at the bottom of the outer shell 1. The tensioning component 215 adapts to the displacement of the screen 216 during vibration, preventing the screen 216 from being stretched and damaged due to vibration.

[0025] The conveying assembly 24 is located at the bottom of the housing 1 and is used to convey the separated debris. The conveying assembly 24 includes a conveying motor 241 fixedly installed on the outside of the housing 1. An auger 242 is embedded in the tubular structure at the bottom of the housing 1. A pulley 243 is fixedly installed at one end of the central shaft of the auger 242. A linkage belt 244 is sleeved on the outside of the pulley 243.

[0026] Specifically, the two augers 242 are linked by the pulley 243 and the linkage belt 244 so that the conveying motor 241 can drive the two augers 242 to rotate at the same time. The outer edge of the auger 242 is provided with a rubber strip that contacts the tubular structure at the bottom of the outer shell 1 to prevent debris from damaging the edge of the auger 242 and the inner wall of the outer shell 1. When the auger 242 rotates, it will drive the debris to be discharged from the opening structure on one side of the outer shell 1.

[0027] The separation mechanism 2 also includes a linkage component 25, which includes a synchronous pulley 251 sleeved on the outside of the corresponding shaft, and a synchronous belt 252 sleeved on the outside of the synchronous pulley 251.

[0028] Specifically, the synchronous pulley 251 and the synchronous belt 252 enable the corresponding shafts to rotate in the same direction and at the same speed.

[0029] This invention also discloses an operation method for an automated separation and treatment system for filter residue from machine tool cutting waste fluid, comprising the following steps: S1: The cutting fluid is introduced into the filter assembly 21 inside the housing 1 through the diversion channel 211 at the top of the housing 1 to filter the cutting fluid. The debris falls into the tubular structure at the bottom of the housing 1 under the guidance of the screen 216 and is discharged. The liquid is discharged through the pipe structure at the front end of the housing 1. S2: The high-pressure airflow generated by the back-blowing component 22 back-blowing cleans the screen 216 and guides the debris through the inclined structure at the bottom of the outer shell 1 into the tubular structure at the bottom of the outer shell 1. S3: Vibration of screen 216 is caused by vibration component 23. During the upward movement of screen 216, the debris stuck in the mesh of screen 216 is pushed out by movable pin 236. At the same time, during the downward movement of screen 216, the debris stuck in the mesh of screen 216 is dislodged from screen 216 by inertia. S4: Debris inside the tubular structure at the bottom of the housing 1 is conveyed out of the housing 1 by the conveying assembly 24.

[0030] Specifically, the transmission motor 219 is model Y132M-4, the air compressor 221 is model KS37-8, the drive motor 233 is model YE2-112M-4, and the conveyor motor 241 is model Y100L-2. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] During operation, the cutting fluid first enters the equipment evenly through the diversion channel 211 at the top of the outer casing 1. Inside the outer casing 1, the limiting frame 217 restricts the flow range of the fluid via connecting plates 2171, connecting bridges 2172, partitions 2173, and limiting plates 2174, ensuring that all the fluid enters the screen 216 area between the two limiting discs 213 (composed of connecting discs 2131 and movable discs 2132). The limiting discs 213, in conjunction with the guide shaft 212, tensioning assembly 215 (including movable shaft 2151, limiting shaft 2152, and return spring 2153), and two drive shafts 218, guide four chains 214 (divided into inner and outer groups) on both sides to move the screen 216. The inner and outer screens... The movement path of screen 216 is a similar circular structure with a notch at the top, with the outer large-aperture screen 216 having a larger path size and wrapping around the inner small-aperture screen 216; the two drive shafts 218 rotate synchronously under the drive of the drive motor 219 and the linkage assembly 25 (including synchronous pulley 251 and synchronous belt 252), and the toothed discs of different sizes on both sides provide power for the chain 214 drive, while strictly limiting the movement speed of screen 216 to avoid misalignment of the movable pin 236 with the mesh of screen 216 due to excessive movement, excessive collision force, and thus damage to screen 216; the tensioning assembly 215 automatically compensates for the tension of chain 214 and adapts to subsequent vibration displacement; when waste liquid passes through, the outer large-aperture screen The screen 216 first intercepts large particles of debris, and then the inner small-aperture screen 216 filters out small particles of debris. The filtered liquid is guided by the inclined surface at the bottom front of the outer shell 1 and discharged from the front pipe. Both coarse and fine debris move with the screen 216 to the vertical structure in the movement path at the rear of the screen 216 and fall down. Because the bends in the paths of the inner and outer screens 216 are staggered, large particles of debris fall into the tubular structure at the bottom rear of the outer shell 1, and small particles of debris fall into the tubular structure at the front, achieving graded collection. At the same time, the air compressor 221 of the backflush assembly 22 generates high-pressure airflow, which is delivered to the four backflush pipes 224 through the diverter pipe 222 and the hose 223. The flat nozzles 225 expand the airflow coverage and increase the flow rate, thus improving the surface of the screen 216. Backflushing cleans and guides debris to fall precisely into the corresponding tubular structure; for stubborn debris inside the mesh, the drive motor 233 of the vibration component 23 drives four eccentric shafts 231 to rotate synchronously through the transmission belt 232 and the linkage component 25. The eccentric wheel periodically lifts the chain 214 to make the screen 216 vibrate up and down, using inertia to loosen the debris. At the same time, the limiting tube 235 and the movable pin 236 (with a buffer spring 237 on the outside) on the mounting plate 234 accurately pass through the mesh and push out the debris when the screen 216 moves up. The previously limited movement speed of the screen 216 is matched with the vibration frequency to ensure that the movable pin 236 can be smoothly aligned with the mesh and gently push out the debris, further avoiding damage to the screen 216.Finally, the conveying motor 241 of the conveying assembly 24 drives the two augers 242 to rotate synchronously via the pulley 243 and the linkage belt 244. The rubber strips on the outer edge of the augers 242 are in contact with the inner wall of the tubular structure, conveying coarse and fine debris from the front and rear tubular structures out of the outer shell 1 respectively. The entire system, through the coordinated linkage of its components, achieves automated filter cake separation, deep cleaning, and graded collection, thoroughly solving the problems of debris accumulation, mesh clogging, and incomplete cleaning.
