Description

Technical Field

[0001] The invention relates to the technical field of separation devices, and in particular to a separation device for separating liquid from iron filings. Background Art

[0002] During the machining process, iron chips are formed as the machine tool cuts the surface of the workpiece. At the same time, cutting fluid needs to be sprayed on the workpiece during the cutting process to cool it down, so that the iron chips and cutting fluid are mixed. For example, in the common nut processing, the holes inside the nut can be drilled, and the thread processing inside the nut can be done by cutting, turning, milling and grinding. When the amount of iron chips formed during batch processing of nuts is large, the iron chips must be separated from the cutting fluid, and the iron chips can be collected and reused after separation.

[0003] The Chinese patent application document with application publication number CN110898486A discloses a negative pressure chip-liquid separator, including a shell, a reducer and a transmission shaft. The shell includes a horizontal section and a lifting section. The reducer is installed on the outside of the lifting section. The transmission shaft passes through the shell and is connected to the shaft of the reducer. A conveyor belt, a filter assembly and a negative pressure assembly are arranged in the shell. The conveyor belt is an annular closed structure. The motion trajectory matches the shape of the shell. One end of the conveyor belt is located in the horizontal section of the shell, and the other end is connected to the transmission shaft. The filter assembly is installed on the inner side of the horizontal section of the shell and is located in the closed space of the conveyor belt. The negative pressure assembly is installed on the outside of the shell and corresponds to the filter assembly. The shell is provided with a through liquid supply port at the position where the negative pressure assembly and the filter assembly are connected. The filter assembly is connected to the negative pressure assembly through the liquid supply port, so that the filter assembly filters the cutting fluid in the horizontal section of the shell. The cutting fluid enters the filter assembly, and the negative pressure assembly sucks the filtered cutting fluid, thereby transporting the filtered cutting fluid to a designated position. The conveyor belt includes a scraper chain and a plurality of scraper plates. There are two scraper chains symmetrically arranged on the two inner surfaces of the shell. The plurality of scraper plates are installed on the two scraper chains at intervals. Through the movement of the scraper chains, the scraper plates move the iron chips from the horizontal section of the shell to the other end of the shell, so that the iron chips are separated from the cutting fluid.

[0004] However, when the scraper plate scrapes the iron chips out of the cutting fluid, the cutting fluid adheres to the surface of the iron chips, or part of the cutting fluid is buried inside the iron chips, so that part of the cutting fluid is removed together with the iron chips, which on the one hand causes a waste of the cutting fluid, and on the other hand, the cutting fluid is easily deteriorated when mixed in the iron chips for a long time, thereby causing the iron chips to rust and affecting the reuse of the iron chips. Summary of the invention

[0005] The invention provides a separation device for separating liquid from iron chips, aiming to solve the problem in the related art that after the iron chips are scraped out from the cutting fluid, the iron chips are mixed with the cutting fluid, which easily causes rust on the iron chips.

[0006] A separation device for separating liquid from iron filings of the present invention comprises a shell and a conveyor belt arranged inside the shell, the shell comprising a horizontal section and a lifting section connected to one end of the horizontal section, and also comprising: a filter cartridge, the filter cartridge is rotatably connected in the shell, and the filter cartridge is at a position where the horizontal section and the lifting section are connected; a bottom plate, the upper surface of the bottom plate is used to carry iron filings, the bottom plate comprises a bottom plate one and a bottom plate two, the bottom plate one is parallel to the horizontal section, the bottom plate one is inclined upward near one end of the filter cartridge and is tangent to the outer wall of the filter cartridge, the bottom plate two is parallel to the lifting section, the bottom plate two is horizontal near one end of the filter cartridge and is tangent to the upper part of the peripheral wall of the filter cartridge; a negative pressure component, the negative pressure component is arranged inside the filter cartridge and corresponds to the portion of the outer wall of the filter cartridge between the bottom plate one and the bottom plate two, the airflow formed by the negative pressure component enters the inner side of the filter cartridge from the outer side of the filter cartridge.

[0007] The effect is that the shell includes a horizontal section and a lifting section, the horizontal section contains cutting fluid, and the depth of the cutting fluid is higher than the bottom plate one, the upper surface of the bottom plate one receives iron chips, and the conveyor belt moves the iron chips on the upper surface of the bottom plate one, so that the iron chips move to the position of the filter cartridge. Since the end of the bottom plate one close to the filter cartridge is tangent to the outer wall of the filter cartridge, the iron chips will transition from the bottom plate one to the filter cartridge, and at the same time, the filter cartridge is rotatably connected to the shell, so that the iron chips continue to move toward the bottom plate two under the rotation of the filter cartridge, and at the same time, the negative pressure component arranged inside the filter cartridge forms an airflow from the outside of the filter cartridge to the inside of the filter cartridge. When the iron chips reach the filter cartridge from the bottom plate one, they have been fished out of the cutting fluid, and part of the cutting fluid mixed in the iron chips will be removed from the iron chips under the action of the airflow. At the same time, the iron chips themselves are breathable, and the airflow can pass through the inside of the iron chips, thereby separating the liquid in the iron chips and reducing the rusting of the iron chips caused by the cutting fluid mixed in the iron chips.

[0008] Preferably, the negative pressure assembly includes an air collecting hood and a fixed pipe, the fixed pipe is located in the center of the filter cartridge, one end of the fixed pipe is located in the filter cartridge, and the other end extends from the filter cartridge for connecting to a vacuum pump, the air collecting hood faces the inner wall of the filter cartridge and corresponds to the inner wall of the filter cartridge between bottom plates one and two, and the air collecting hood is connected to the fixed pipe.

[0009] Preferably, a vibration assembly is provided inside the filter cartridge, the vibration assembly includes a top plate and a guide rod, the guide rod is slidably connected to the wind collecting hood, the top plate is fixed to one end of the guide rod, and the top plate is used to impact the inner wall of the filter cartridge under the action of the guide rod.

[0010] The effect is that the vibration component is arranged inside the filter cartridge. When there are iron filings on the outer wall of the filter cartridge, the top plate impacts the inner wall of the filter cartridge under the action of the guide rod, causing the side wall of the filter cartridge to vibrate, thereby causing the iron filings on the outer wall of the filter cartridge to vibrate as well. On the one hand, the iron filings can be dispersed, and on the other hand, the iron filings can be turned over, thereby making it easier for the cutting fluid in the iron filings to be sucked away through the negative pressure component, further reducing the liquid content in the iron filings.

[0011] Preferably, a spring is sleeved on the guide rod, one end of the spring is fixed on the guide rod, and the other end is fixed on the wind collecting hood. The force of the spring on the guide rod is used to drive the top plate to approach the inner wall of the filter cartridge. The guide rod is connected to a driving assembly, and the driving assembly is used to drive the guide rod to move the top plate away from the inner wall of the filter cartridge.

[0012] The effect is that the force of the spring on the guide rod is used to drive the top plate to approach the inner wall of the filter cartridge. When the drive assembly drives the guide rod to move the top plate away from the inner wall of the filter cartridge, the drive assembly releases the drive on the guide rod, so that the force of the spring automatically vibrates the side wall of the filter cartridge. Due to the setting of the spring, the filter cartridge can still rotate when it is impacted to avoid jamming of the filter cartridge.

[0013] Preferably, at least two vibration components are arranged at intervals along the rotation direction of the filter cartridge, and one of the vibration components is arranged at a position corresponding to the highest point of the filter cartridge.

[0014] The effect is that the vibration component at the highest point of the filter cartridge can make the iron filings separate from the filter cartridge upward under the action of vibration, so that the iron filings can be more easily transferred from the filter cartridge to the bottom plate 2; at the same time, the two vibration components can make the iron filings on the filter cartridge vibrate multiple times, thereby improving the turning effect of the iron filings.

[0015] Preferably, the driving assembly includes a rotating wheel and a shift fork, the rotating wheel is coaxially fixed on the filter cartridge, a plurality of notches are provided on the peripheral wall of the rotating wheel, the shift fork is rotatably connected to the wind collecting hood, one end of the shift fork is used to abut against the peripheral wall of the rotating wheel, and the other end is used to drive the guide rod to move, and when the shift fork enters the notch, the shift fork releases the drive on the guide rod.

[0016] The effect is that: a plurality of notches are provided on the rotating wheel. When the shift fork rotates to the position of the notch, the shift fork releases the drive on the guide rod, so that the guide rod can drive the top plate to vibrate the inner wall of the filter cartridge. When the position between the two notches of the rotating wheel abuts against the shift fork, the top plate can be kept separated from the inner wall of the filter cartridge, thereby reducing the impact on the rotation of the filter cartridge.

[0017] Preferably, the filter cartridge includes two end plates and a mesh peripheral wall plate, the two end plates are spaced apart and are both rotatably connected to the shell, the mesh peripheral wall plate is cylindrical and sleeved on the two end plates, and the mesh peripheral wall plate is detachably connected to the end plates.

[0018] Preferably, the conveyor belt comprises a scraper chain and a plurality of scraper plates spaced apart along the length direction of the scraper chain, and the scraper plates on the upper part of the scraper chain abut against the bottom plate 1, the filter cartridge and the bottom plate 2 in sequence as the scraper chain moves.

[0019] Preferably, a sprocket is coaxially fixedly arranged on the filter cartridge, and the sprocket is meshed with the scraper chain.

[0020] The effect is that a sprocket is set on the filter cartridge and meshes with the sprocket through a scraper chain, so that the rotation speed of the scraper plate on the scraper chain and the filter cartridge is as similar as possible, so that the iron chips at the filter cartridge position and the movement of the scraper plate are in a synchronized state, so that when the iron chips reach the bottom plate 2, they can still be pushed by the scraper plate.

[0021] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0022] The present invention forms an airflow from the outside of the filter cartridge to the inside of the filter cartridge through the negative pressure component arranged inside the filter cartridge. When the iron filings reach the filter cartridge from the bottom plate, they have been fished out of the cutting fluid. Part of the cutting fluid mixed in the iron filings will be separated from the iron filings under the action of the airflow. At the same time, the iron filings themselves are breathable, which can allow the airflow to pass through the inside of the iron filings, thereby separating the liquid in the iron filings and reducing the rust of the iron filings caused by the cutting fluid mixed in the iron filings. At the same time, when there are iron filings on the outer wall of the filter cartridge, the top plate impacts the inner wall of the filter cartridge under the action of the guide rod, so that the iron filings on the outer wall of the filter cartridge also vibrate, which can disperse the iron filings on the one hand and turn over the iron filings on the other hand, so that the cutting fluid in the iron filings can be more easily sucked away by the negative pressure component.

[0030] Combine the following Figures 1 to 5 Embodiments of the present invention are described in detail, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0031] A separation device for separating liquid from iron filings of the present invention, such as Figure 1 and Figure 2 As shown, it includes a housing 1 and a conveyor belt 2 arranged inside the housing 1. The housing 1 includes a horizontal section 11 and a lifting section 12. One end of the horizontal section 11 is connected to the lower end of the lifting section 12. The conveyor belt 2 is arranged along the horizontal section 11 and the lifting section 12 of the housing 1. The conveyor belt 2 is used to convey the iron filings in the horizontal section 11 to the lifting section 12 away from one end of the horizontal section 11. There is cutting fluid inside the horizontal section 11, and the depth of the cutting fluid is lower than the top surface of the horizontal section 11. A rotating filter cartridge 3 is arranged at the position where the horizontal section 11 and the lifting section 12 are connected. The rotation axis of the filter cartridge 3 is arranged horizontally and perpendicular to the horizontal section 11. A bottom plate is arranged inside the housing 1. The bottom plate includes a bottom plate 1 41 arranged inside the horizontal section 11 and a bottom plate 2 42 arranged inside the lifting section 12. The bottom plate 1 41 is arranged parallel to the horizontal section 11, and the bottom plate 2 42 is arranged parallel to the lifting section 12. The bottom plate is arranged at a distance from the bottom of the housing 1. At the same time, there are side plates 43 on both sides of the bottom plate 1 41 and the bottom plate 2 42. The upper surface of the bottom plate 1 41 is used to receive iron filings. At the same time, the side plates 43 prevent the iron filings from flowing from the two sides of the bottom plate 1 41 to the bottom of the shell 1. The bottom plate 1 41 is inclined upward at one end close to the filter cartridge 3 and is tangent to the outer wall of the filter cartridge 3. The bottom plate 2 42 is horizontally arranged at one end close to the filter cartridge 3 and is tangent to the outer wall of the filter cartridge 3.

[0032] When in use, the position where the filter cartridge 3 is tangent to the bottom plate 1 41 is higher than the liquid level of the cutting fluid, and the conveyor belt 2 moves the iron chips along the bottom plate 1 41. When the iron chips reach the position where the bottom plate 1 41 is tangent to the filter cartridge 3, the iron chips are transferred from the bottom plate to the filter cartridge 3, and continue to move with the rotation of the filter cartridge 3. The cutting fluid inside the iron chips can be filtered through the filter cartridge 3 to reduce the liquid content in the iron chips. The rotation direction of the upper part of the filter cartridge 3 is from the bottom plate 1 41 to the bottom plate 2 42. The filter cartridge 3 keeps rotating and is in the same direction as the movement of the iron chips to reduce the sliding of the iron chips on the surface of the filter cartridge 3, thereby reducing the iron chips from entering the mesh of the filter cartridge 3. When the iron chips reach the position of the bottom plate 2 42 with the filter cartridge 3, the iron chips are transferred from the filter cartridge 3 to the bottom plate 2 42, and continue to move with the conveyor belt 2, so that the iron chips are discharged.

[0033] In order to make the filter cartridge 3 have a better filtering effect on iron chips and prevent iron chips from entering the filter cartridge 3, the mesh diameter of the filter cartridge 3 is set to 0.1-1mm. However, due to the capillary action of the cutting fluid, the liquid cannot freely pass through the filter cartridge 3 by its own gravity. Figure 3 A negative pressure component 5 is installed inside the filter cartridge 3 , and the negative pressure component 5 is used to suck the liquid in the iron filings on the filter cartridge 3 .

[0034] refer to Figure 1 , Figure 2 and Figure 3 The negative pressure component 5 includes an air collecting hood 51 arranged inside the filter cartridge 3 and a fixed pipe 52 arranged at the center of the filter cartridge 3. The center line of the fixed pipe 52 coincides with the center line of the filter cartridge 3. One end of the fixed pipe 52 is in the filter cartridge 3, and the other end extends from one end of the filter cartridge 3, so that the fixed pipe 52 is connected to an air pump 53, and a water-gas separator 54 is arranged between the air pump 53 and the fixed pipe 52. The air collecting hood 51 is arranged close to the inner wall of the filter cartridge 3, and the air collecting hood 51 and the fixed pipe 52 are connected by a plurality of support pipes 55, so that the air pump 53 exhausts air through the air collecting hood 51, so that the gas outside the filter cartridge 3 enters the air collecting hood 51 through the side wall of the filter cartridge 3, and the area where the air collecting hood 51 is covered on the inner wall of the filter cartridge 3 is between the bottom plate 1 41 and the bottom plate 2 42, and is located above the liquid level of the cutting fluid. When the iron filings are close to the filter cartridge 3 along with the bottom plate 41, the iron filings are fished out of the cutting fluid, and most of the cutting fluid can be drained out; when the iron filings move on the filter cartridge 3, the liquid in the iron filings will enter the filter cartridge 3 along with the airflow formed by the air collecting cover 51. Because the inside of the iron filings is a porous structure, the airflow can easily pass through the inside of the iron filings to take away the liquid, and at the same time, the liquid becomes mist and can pass through the filter cartridge 3 smoothly under the action of the airflow. When the liquid passes through the air collecting cover 51 and enters the water-gas separator 54, the liquid is collected in the water-gas separator 54, and the collected cutting fluid can be reused, while reducing the impact on the vacuum pump 53. The airflow formed by the negative pressure component 5 flows from the outside of the filter cartridge 3 to the inside of the filter cartridge 3, which can break the balance of the liquid in the mesh of the filter cartridge 3, so that the liquid passes through the filter cartridge 3 in time.

[0035] The filter cartridge 3 includes two end plates 31 and a mesh peripheral wall plate 32. The two end plates 31 are rotatably connected to the frame. The two end plates 31 are arranged opposite to each other and at intervals. The mesh peripheral wall plate 32 is detachably fixed to the peripheral walls of the two end plates 31. The mesh peripheral wall plate 32 is made of a stainless steel mesh, so that the mesh peripheral wall plate 32 can be replaced. At the same time, the mesh peripheral wall plate 32 has a large strength, which reduces deformation under the action of the negative pressure component 5. The mesh peripheral wall plate 32 and the end plate 31 can be connected by screws that penetrate the mesh peripheral wall plate 32 and are then threadedly connected to the peripheral wall of the end plate 31 for fixing. An end plate 31 is respectively arranged at both ends of the cylindrical structure formed by the mesh peripheral wall plate 32.

[0036] refer to Figure 1 , Figure 2 and Figure 4A sprocket 33 is coaxially fixed on each end plate 31. The conveyor belt 2 includes a scraper chain 21 and a plurality of scraper plates 22. Two scraper chains 21 are provided and symmetrically arranged on the inner side of the housing 1. The scraper chain 21 is arranged in a closed ring. The plurality of scraper plates 22 are evenly spaced along the length direction of the scraper chain 21. The scraper plates 22 located at the upper part of the scraper chain 21 can abut against the bottom plate 1 41, the filter cartridge 3 and the bottom plate 2 42 in sequence when the scraper chain 21 moves. The scraper plates 22 are long strips, and the cross section of the scraper plates 22 is set to be L-shaped in this embodiment. The two ends of the scraper plates 22 are respectively fixed on the two scraper chains 21. At the same time, the scraper chains 21 are meshed with the sprocket 33 at the position of the filter cartridge 3, so that the speed at which the sprocket 33 drives the filter cartridge 3 to rotate is as close as possible to the speed at which the scraper plates 22 move, so that the scraper plates 22 and the iron filings on the filter cartridge 3 can move synchronously.

[0037] refer to Figure 2 A vibration component 6 for vibrating the mesh peripheral wall plate 32 of the filter cartridge 3 is provided inside the filter cartridge 3. The position of the vibration component 6 for driving the mesh peripheral wall plate 32 to vibrate is between the bottom plate 1 41 and the bottom plate 2 42, so that the vibration component 6 vibrates the iron filings on the filter cartridge 3. The iron filings may be in a pile due to the transportation of the scraper plate 22. When the vibration component 6 vibrates the mesh peripheral wall plate 32 of the filter cartridge 3, the iron filings may jump up and down, so that the liquid in the iron filings is more easily blown by the airflow. At the same time, the iron filings that fall back onto the filter cartridge 3 after the vibration are more easily dispersed, so that the liquid in the iron filings is exposed.

[0038] The vibration assembly 6 includes a top plate 61, a guide rod 62 and a spring 63. The guide rod 62 is slidably connected to the wind collecting cover 51. One end of the guide rod 62 is located inside the wind collecting cover 51, and the other end extends to the outside of the wind collecting cover 51. The top plate 61 is fixed at one end of the guide rod 62 located inside the wind collecting cover 51. The top plate 61 can abut against the inner wall of the mesh peripheral wall plate 32 as the guide rod 62 moves, and the shape of one side of the top plate 61 used to abut against the mesh peripheral wall plate 32 should match the inner wall of the filter cartridge 3, so that the contact surface between the top plate 61 and the mesh peripheral wall plate 32 is larger, reducing the deformation of the filter cartridge 3 caused by impact. The spring 63 is sleeved on the guide rod 62, one end of the spring 63 is fixedly connected to the wind collecting cover 51, and the other end is fixedly connected to the guide rod 62, so that the force of the spring 63 on the guide rod 62 is used to drive the top plate 61 to move toward the inner wall of the filter cartridge 3. At the same time, even if the top plate 61 remains in contact with the mesh peripheral wall plate 32 under the action of the spring 63 , the filter cartridge 3 can still overcome the friction force of the top plate 61 on the mesh peripheral wall plate 32 and continue to rotate.

[0039] In this embodiment, two vibration assemblies 6 are provided, and the two vibration assemblies 6 are arranged at intervals along the rotation direction of the filter cartridge 3, and are respectively used to abut different parts of the mesh peripheral wall plate 32, so as to vibrate the iron filings on the filter cartridge 3 at least twice. The top plate 61 in one of the vibration assemblies 6 can be set at a position corresponding to the highest point of the filter cartridge 3, so that the vibration assembly 6 can more easily transfer the iron filings from the filter cartridge 3 to the second bottom plate 42 during the process of vibrating and jumping them off.

[0040] refer to Figure 4 and Figure 5 , a driving assembly 7 for driving the top plate 61 away from the inner wall of the filter cartridge 3 is connected to the guide rod 62. When the driving assembly 7 releases the drive on the guide rod 62, the spring 63 can quickly move the guide rod 62, so that the top plate 61 vibrates against the iron filings on the side wall of the filter cartridge 3. The driving assembly 7 includes a rotating wheel 71 and a shift fork 72. The rotating wheel 71 is coaxially fixed to the end plate 31 of the filter cartridge 3. A plurality of notches 73 are provided on the peripheral wall of the rotating wheel 71. The shift fork 72 is arranged in a V shape in this embodiment, and the middle part of the shift fork 72 is rotatably connected to the air collecting cover 51. A shift block 74 is fixedly arranged on at least one guide rod 62, one end of the shift fork 72 abuts against the shift block 74, and the other end is used to abut against the peripheral wall of the rotating wheel 71. When one end of the fork 72 is at the position of the notch 73, the driving assembly 7 releases the drive on the guide rod 62; when the fork 72 is misaligned with the notch 73 under the action of the rotation of the rotating wheel 71, the fork 72 will drive the guide rod 62 to move, so that the top plate 61 is away from the inner wall of the filter cartridge 3; when the fork 72 abuts against the position between two adjacent notches 73 on the peripheral wall of the rotating wheel 71, the fork 72 can keep the top plate 61 and the mesh peripheral wall plate 32 in a separated state, thereby reducing the resistance caused to the rotation of the filter cartridge 3.

[0041] The process of separating liquid from iron filings in this embodiment is as follows:

[0042] When the iron chips fall into the housing 1, they are on the bottom plate 41, and then the scraper plate 22 moves along with the scraper chain 21, driving the iron chips to move on the bottom plate 41. When the iron chips reach the position where the bottom plate 41 is connected to the filter cartridge 3, the iron chips will be scraped onto the outer wall of the filter cartridge 3. At the same time, the filter cartridge 3 can rotate synchronously with the scraper plate 22 to move the iron chips. When the iron chips reach the filter cartridge 3, the iron chips have been fished out of the cutting fluid in the housing 1. Under the action of the negative pressure component 5, the residual liquid in the iron chips can continue to be separated. At the same time, when the vibration group When the component 6 vibrates against the mesh wall plate 32, the iron chips will also jump, thereby dispersing the iron chips and making it easier for the airflow formed by the negative pressure component 5 to separate the liquid in the iron chips. Until the iron chips rotate with the filter cartridge 3 to the edge of the bottom plate 42, the iron chips transition from the filter cartridge 3 to the bottom plate 42, and at the same time, the scraper plate 22 continues to move with the iron chips under the action of the scraper chain 21, so that under the joint action of the negative pressure component 5 and the vibration component 6, the liquid in the iron chips can be further separated, reducing the amount of cutting fluid contained in the collected iron chips.
