Description

Technical Field

[0001] This invention relates to a separation device, and more particularly to a solid-liquid separation device. Background Technology

[0002] As an essential lubricating and cooling medium in machining, cutting fluid will gradually accumulate solid cuttings over time, leading to a deterioration in its quality.

[0003] Based on the current consensus on environmental protection requirements, it is believed that oily metal shavings are dry hazardous waste and can only be disposed of as recyclable industrial waste after being briquetteed and packaged.

[0004] In existing technologies, briquetting equipment is used to press waste chips into briquettes, squeezing out the cutting fluid. However, this method uses briquetting equipment that is expensive and difficult to maintain, resulting in high environmental treatment costs.

[0005] In existing technologies, another method involves using a wire mesh to drain the cutting fluid from the chips. However, this method requires a very long time for the cutting fluid to drain, making it inefficient.

[0006] In addition, there are many workstations involving metal chips in different processes, and the types of metals and the oil content of the metal chips are not exactly the same. The actual cutting fluid situation is also quite complicated, making it difficult to treat by briquetting or draining. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent device for solid-liquid separation of cutting fluid, which can separate solids and liquids in cutting fluid through centrifugation. Furthermore, by adjusting the opening angle of the spin-drying blades, the time of chip drying can be controlled, thereby achieving intelligent adjustment and making the separation process of chips and cutting fluid more efficient.

[0008] To achieve the above objectives, the present invention proposes an intelligent device for solid-liquid separation of cutting fluid, comprising:

[0009] A solid-liquid separation cylinder includes: an inner hopper for containing solid chips, an outer hopper for containing liquid located around the inner hopper, and an inclined unloading chute located above the inner hopper and the outer hopper.

[0010] A centrifugal device is disposed inside the solid-liquid separation cylinder. The centrifugal device includes a support wheel and a plurality of spin-drying blades distributed along the circumference of the support wheel and connected to the support wheel. The spin-drying blades have small holes that allow liquid to pass through while preventing solid chips from passing through, so that the liquid passes through the spin-drying blades and enters the outer hopper.

[0011] A drive assembly, connected to the support wheel, drives the support wheel to rotate around its own axis, thereby causing the spin-drying blades to open relative to each other in the radial direction of the support wheel and rotate with the rotation of the support wheel, so as to spin-dry the solid chips that fall onto the spin-drying blades via the unloading chute.

[0012] The spin-drying blade angle adjustment device includes a large circular ring located around the spin-drying blade, which can move up and down along the height direction of the solid-liquid separation cylinder to adjust the angle at which the spin-drying blades are relatively open to each other in the radial direction of the support wheel.

[0013] When the cutting fluid solid-liquid separation intelligent device is working, the solid chips that fall onto the drying blades via the unloading slide are dried. The outer hopper receives the spun liquid, and the inner hopper receives the solid chips.

[0014] Furthermore, in the intelligent cutting fluid solid-liquid separation device of the present invention, the driving component includes:

[0015] Electric motor;

[0016] The first pulley is connected to the output shaft of the motor;

[0017] The second pulley is connected to the first pulley via a belt, and the bracket wheel is connected to the second pulley to rotate synchronously with the second pulley.

[0018] Furthermore, the intelligent cutting fluid solid-liquid separation device of the present invention also includes a feeding funnel, which is located above the unloading slide.

[0019] Furthermore, in the intelligent cutting fluid solid-liquid separation device of the present invention, the large ring includes an outer ring and an inner ring that can rotate relative to the outer ring. When the spin-drying blades are open relative to each other in the radial direction of the support wheel, the inner ring is in contact with the spin-drying blades; ball bearings are provided between the outer ring and the inner ring.

[0020] Furthermore, in the intelligent cutting fluid solid-liquid separation device of the present invention, the surface in contact between the inner ring and the spin-drying blade is an arc surface.

[0021] Furthermore, in the intelligent cutting fluid solid-liquid separation device of the present invention, the spin-drying blade angle adjustment device further includes:

[0022] An upright, fixed sliding rod;

[0023] A sliding block is provided on a fixed sliding rod and can slide up and down along the fixed sliding rod. The large ring is fixedly connected to the sliding block. An oil baffle is provided on the outer side of the large ring in the radial direction to engage with the wall of the solid-liquid separation cylinder in the circumferential direction.

[0024] A slider drive assembly, which is connected to the slider to drive the slider to slide up and down along a fixed slide bar.

[0025] Furthermore, in the intelligent cutting fluid solid-liquid separation device of the present invention, the sliding block drive assembly includes:

[0026] Columns;

[0027] A fixing block is fixedly disposed on the upper part of the fixing slide rod;

[0028] A linkage assembly is mounted on a column. The linkage assembly includes several linkages that are hinged to each other. The upper end of the linkage assembly is connected to a fixed block, and the lower end of the linkage assembly is connected to a sliding block. The linkage assembly is also connected to the column.

[0029] A cylinder, which is connected to the connecting rod assembly, wherein the extension and retraction of the piston rod of the cylinder adjusts the bending angle of the connecting rod assembly to adjust the distance between the sliding block and the fixed block.

[0030] Furthermore, in the intelligent cutting fluid solid-liquid separation device of the present invention, the piston rod of the cylinder is horizontally arranged; a horizontally extending through groove is provided on the fixed block; a horizontally extending through groove is provided on the sliding block; a through groove extending along its height is provided on the column; the connecting rod assembly includes: an upper connecting rod with an upper connecting rod shaft at its upper end, the upper connecting rod shaft being inserted into the fixed block through groove and the through groove of the column; an intermediate connecting rod with its upper end hinged to the lower end of the upper connecting rod; the middle part of the intermediate connecting rod being rotatably connected to a rotating shaft, the rotating shaft being inserted into the through groove of the column; a lower connecting rod with its upper end hinged to the lower end of the intermediate connecting rod, the upper end of which has a lower connecting rod shaft, the lower connecting rod shaft being inserted into the sliding block through groove and the through groove of the column; the intermediate connecting rod is also hinged to the piston rod.

[0031] Furthermore, the intelligent cutting fluid solid-liquid separation device of the present invention further includes:

[0032] The counterweight is located below the sliding block on the fixed slide rod and can slide up and down along the fixed slide rod.

[0033] A spring connects the counterweight and the sliding block.

[0034] In this configuration, the downward movement of the large ring, combined with the vibration caused by the tension spring and counterweight, causes the chips stuck on the spin dryer blades to fall off.

[0035] Furthermore, the intelligent cutting fluid solid-liquid separation device of the present invention further includes:

[0036] The lifting cylinder, located below the counterweight, is used to lift the counterweight.

[0037] Locating pins are used to fix the position of the counterweight in the height direction.

[0038] The intelligent cutting fluid solid-liquid separation device of the present invention has the following advantages and beneficial effects:

[0039] The intelligent cutting fluid solid-liquid separation device of the present invention can separate solids and liquids in the cutting fluid through centrifugation. Furthermore, the time of chip drying can be controlled by adjusting the opening angle of the spin-drying blades, thereby making the separation process of solid chips and cutting fluid more efficient.

[0040] In a preferred embodiment of the present invention, when too much metal shavings accumulate on the spin dryer blades, the downward movement of the large ring can be superimposed by the counterweight and tension spring, thereby causing the shavings stuck on the spin dryer blades to fall off.

[0058] The intelligent device for solid-liquid separation of cutting fluid according to the present invention will be further explained and described below with reference to the accompanying drawings and specific embodiments. However, such explanation and description do not constitute an undue limitation on the technical solution of the present invention.

[0059] Figure 1 The diagram shows the overall structure of the intelligent cutting fluid solid-liquid separation device according to one embodiment of the present invention.

[0060] Figure 2 The diagram shows a structural view of the cutting fluid solid-liquid separation intelligent device according to the present invention with the top cover 10 removed in one embodiment.

[0061] Figure 3 The image shows a top view of one embodiment of the intelligent cutting fluid solid-liquid separation device of the present invention.

[0062] Figure 4 Showing Figure 3 Sectional view at point CC.

[0063] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the intelligent cutting fluid solid-liquid separation device of the present invention is mounted on the ground via a support 1. The intelligent cutting fluid solid-liquid separation device may include a solid-liquid separation cylinder 2. The solid-liquid separation cylinder includes a solid-liquid separation hopper 12.

[0064] like Figure 5 As shown, the solid-liquid separation hopper includes an inner hopper 121 and an outer hopper 122 located around the inner hopper. A discharge chute 123 is located inside the solid-liquid separation cylinder and above the solid-liquid separation hopper. During operation, the cutting fluid to be separated passes through the discharge chute 123, where solid cutting chips fall into the inner hopper 121, and the ejected liquid falls into the outer hopper. The bottom of the outer hopper has a drain port P (e.g., ...). Figure 16 As shown in the image, the cutting fluid can be drained.

[0065] Continue reading Figure 4 The feed hopper 8 is positioned above the discharge chute 123 via the support 1. The intelligent device for solid-liquid separation of cutting fluid also includes a centrifugal device, which is located inside the solid-liquid separation cylinder 2. The centrifugal device includes a support wheel 11 and several spin-drying blades 26 distributed along the circumference of the support wheel and connected to the support wheel.

[0066] Figure 6 The connection structure of the support wheel and the spin-drying blades in one embodiment of the intelligent cutting fluid solid-liquid separation device of the present invention is shown.

[0067] Figure 7 show Figure 6 A magnified view of section II in the middle.

[0068] like Figure 6 and Figure 7 As shown, in some embodiments, the support wheel 11 has several holes arranged circumferentially within it. One end of the T-shaped bracket 27 is fixed inside the hole of the support wheel 11, and the other end of the T-shaped bracket 27 is fitted onto the ring 28 through the hole to separate two adjacent spin-drying blades. The spin-drying blade 26 is arc-shaped like a tile, with a blade shaft 261 extending along its length on one side. The spin-drying blade 26 is fitted onto the ring 28 through the hole at the upper end of the blade shaft 261, and is clearance-fitted with it. In some embodiments, a rubber sheet can also be provided on the other side of the spin-drying blade relative to the blade shaft to fill the gap between adjacent spin-drying blades and prevent cutting fluid from leaking out of the gap. In addition, two layers of spin-drying blades can be provided on the ring to ensure overlap. Small holes are opened on the spin-drying blade 26 to prevent chips from passing through, but cutting fluid can pass through. Since the purpose of this invention is to remove the cutting fluid from solid chips, some very fine powder may be able to enter the outer hopper with the cutting fluid in certain situations, but large solid chips cannot pass through, so this does not affect the technical effect of this invention.

[0069] The intelligent device for solid-liquid separation of cutting fluid also includes a drive component connected to the support wheel to drive the support wheel to rotate around its own axis, thereby causing the spin-drying blades to open relative to each other in the radial direction of the support wheel and rotate with the rotation of the support wheel, so as to spin-dry the solid chips that fall onto the spin-drying blades via the unloading slide.

[0070] Figure 4 The invention illustrates a drive assembly in one embodiment, comprising a motor 3 fixedly mounted on a bracket 1, the bracket 1 having a hole through which the motor output shaft passes, a first pulley 4 connected to the output shaft of the motor 3 and driven by a key, and a nut 5 for axial positioning; a second pulley 9 connected to the first pulley 4 via a belt 6, the second pulley 9 being connected to the bracket 1 via a tapered roller bearing 7, and a bracket wheel 11 fixedly connected to the second pulley 9 to rotate synchronously with the second pulley 9.

[0071] The intelligent device for solid-liquid separation of cutting fluid also includes a device for adjusting the angle of the spin dryer blades. Figure 4 The invention is shown in one embodiment of the spin dryer blade angle adjustment device.

[0072] like Figure 4 As shown, the spin dryer blade angle adjustment device includes an upright fixed slide bar 13, an upright column 25, a fixed block 21 fixedly mounted on the upper part of the fixed slide bar, a sliding block 18 that can slide up and down along the fixed slide bar 13, a large ring 29 fixedly connected to the sliding block, and a sliding block drive assembly that drives the sliding block 18 to slide up and down along the fixed slide bar.

[0073] In some more specific embodiments, the sliding block drive assembly includes a horizontally arranged cylinder 20, which is mounted via a cylinder bracket 19. The tail of the cylinder 20 is movably connected to a pin hole on the upper part of the cylinder bracket via a pin, allowing the cylinder 20 to rotate around the pin hole. One end of the piston rod of the cylinder 20 is connected to the first shaft 231 of the intermediate connecting rod 23 via a hole, and the first shaft 231 of the intermediate connecting rod 23 can rotate within the hole at one end of the piston rod. The end of the first shaft 231 of the intermediate connecting rod has a retaining spring for axial limiting. The fixed block 21 has a horizontally extending fixed block through groove 211, the sliding block 18 has a horizontally extending sliding block through groove 181, and the column 25 has a column through groove 251 extending along its height direction.

[0074] like Figure 8 As shown, the upper end of the upper connecting rod 22 is provided with an upper connecting rod shaft 221. The upper connecting rod shaft 221 is inserted into the through groove 211 of the fixed block and the through groove 251 of the column, and can rotate around the axis. The end of the upper connecting rod shaft 221 is axially positioned by the sleeve 30 and the retaining spring 31, as shown. Figure 10 , Figure 11 , Figure 12 and Figure 13 shown.

[0075] like Figure 9 The intermediate connecting rod 23 shown has a second shaft 232 inserted into the hole of the upper connecting rod 22 with a clearance fit, achieving a hinge connection with the lower end of the upper connecting rod 22. The end of the second shaft 232 is axially positioned by a retaining spring. The intermediate connecting rod 23 has a hole in its middle section, such as... Figure 10 , Figure 11 and Figure 12 As shown, the rotating shaft 234 is inserted into the hole of the intermediate connecting rod 23 through the column through slot 251 on the column 25 and can rotate around its axis. Similarly, a retaining spring is fixed to the other end of the rotating shaft 234 to ensure axial limitation. The third shaft 233 of the intermediate connecting rod 23 is inserted into the hole of the lower connecting rod 24 and is limited at its end by a retaining spring. Figure 4 , Figure 10 , Figure 11 and Figure 12 As shown, the connecting rod shaft of the lower connecting rod 24 is inserted into the sliding block through groove 181 and the column through groove 251, and one end of the connecting rod shaft of the lower connecting rod 24 is also axially positioned using a snap ring.

[0076] Figure 14 The structure of the sliding block in one embodiment of the intelligent cutting fluid solid-liquid separation device of the present invention is shown.

[0077] Figure 15 Showing Figure 4 A magnified view of a section at point III.

[0078] In one implementation, such as Figure 14 and Figure 15 As shown, the sliding block 18 is fixedly connected to the large ring 29. The large ring 29 includes an outer ring 291 and an inner ring 292. The outer ring 291 rolls in contact with the inner ring 292 through large ball bearings 331 and small ball bearings 332. When the spin-drying blades are open relative to each other in the radial direction of the support wheel, the inner ring 292 contacts the spin-drying blades 26 (e.g., ...). Figure 17 (As shown). The surface of the inner ring 292 that contacts the spin-drying blades is an arc surface H.

[0079] The balls can be positioned relative to each other using a cage. If the large ring and balls do not meet the assembly requirements, the whole unit can be divided into several parts. After installing the balls, the outer ring and inner ring can be assembled into a whole. Two oil baffles 32 can also be symmetrically arranged on the outer side of the large ring 29 to engage with the wall of the solid-liquid separation cylinder in the circumferential direction to prevent the cutting fluid from being thrown out or leaking out of the solid-liquid separation cylinder during the spin-drying process. The other end of the sliding block 18 has a square slider 182 with a round hole that fits with the fixed sliding rod 13 set on one side of the large ring.

[0080] Continue reading Figure 4In a preferred embodiment, the intelligent device for solid-liquid separation of cutting fluid may further include: a counterweight 16, which is disposed on the fixed slide rod 13 through a hole and below the sliding block 18, and can slide up and down along the fixed slide rod 13; a spring 17 connected between the counterweight 16 and the sliding block 18; a lifting cylinder 15 for lifting the counterweight 16; and a hole provided at the lower part of the column, into which a limiting pin 14 is inserted to support the counterweight.

[0081] When the aforementioned intelligent cutting fluid solid-liquid separation device is in operation, the lifting cylinder 15 lifts the counterweight 16 upwards, inserting the limiting pin 14 into the hole on the column 25 to support the counterweight. The piston rod of the cylinder 20 extends, and through the action of the intermediate connecting rod 23, the upper connecting rod 22, and the lower connecting rod 24, the sliding block 18 moves up and down along the fixed sliding rod 13. The up and down sliding of the sliding block 18 drives the large circular ring 29 to move up and down, which can change the opening angle of the spin-drying blades 26.

[0082] When the motor 3 starts running, it drives the support wheel 11 to rotate together through the first pulley 4 and the second pulley 9. Under the action of centrifugal force, the spin-drying blades 26 gradually open. When the spin-drying blades 26 contact the inner arc surface H, the spin-drying blades 26 no longer open. In this way, the opening angle of the spin-drying blades can be controlled.

[0083] Waste cutting fluid is fed into the feed funnel 8. Under the action of the discharge chute 123, solid chips fall onto the high-speed rotating spin-drying blades 26. Under the action of centrifugal force and the spin-drying blades, the chips and the cutting fluid on them generate two components of force in the horizontal and vertical directions. The horizontal centrifugal force component can spin-dry the cutting fluid on the chips. The vertical component of force can make the solid chips fall into the inner hopper 121 of the solid-liquid separation hopper. The cutting fluid is then thrown through the small holes on the spin-drying blades onto the oil baffle 32 and the cylinder wall of the solid-liquid separation cylinder 2, then flows down, and finally is discharged from the cutting fluid drain port P.

[0084] When too many metal shavings accumulate on the spin-drying blades, the lifting cylinder 15 can retract downwards, pulling out the limit pin 14, thus suspending the counterweight 16. After the motor 3 starts, the spin-drying blades 26 open under centrifugal force, the cylinder 20 extends, causing the large ring 29 to move downwards. Under the action of the spring 17 and the counterweight 16, the downward movement of the large ring 29 causes superimposed vibration, thereby causing the chips stuck on the spin-drying blades to fall off.
