AI Technical Summary
In existing technologies, iron filings and foam entrained in cutting fluid are difficult to separate quickly, leading to nozzle blockage, pump wear, valve jamming, reduced heat exchange efficiency, and accelerated degradation of cutting fluid. Furthermore, the foam encapsulating fine debris increases the pressure on subsequent processing.
The fluid is divided into multiple thin streams by inclined plates. Combined with the defoaming net swaying between the inclined plates, the foam and oil film are broken by division and friction, and metal debris is quickly settled. The defoaming net is driven to sway repeatedly in a narrow space by the swaying connection, which increases the settling area and breaks the surface tension.
It enables rapid elimination of foam and sedimentation of metal debris, reduces settling time, prevents foam from carrying debris into subsequent equipment, reduces subsequent processing pressure, and improves the stability of cutting fluid circulation.

Abstract
Description
Technical Field
[0001] This invention relates to the field of machine tool processing technology, specifically to a waste cutting fluid separation and iron filings removal device. Background Technology
[0002] During the machining process, cutting fluid carries iron filings and abrasive shavings of different particle sizes, morphologies, and magnetic states. These solid phases flow into the recovery line with the liquid. If they are not separated in a timely and efficient manner, they will cause problems such as nozzle blockage, pump wear, valve jamming, reduced heat exchange efficiency, and pipeline deposition, and accelerate the degradation of cutting fluid and the generation of odors.
[0003] Waste cutting fluid generated during machine tool machining is typically collected through a collection hopper or drainage channel at the bottom of the machine tool. It is then collected into a centralized settling tank via a push bucket, natural recirculation, or pump suction. After settling in the settling tank, it undergoes further processing through a chip conveyor and paper tape filter. Generally, magnetic capture and mechanical interception are used to classify, collect, and cleanly discharge iron chips, minimizing iron chip entrainment in the cutting fluid, reducing consumption, and maintaining the long-term stable operation of the circulation system.
[0004] Cutting fluids used in turning typically contain a large amount of emulsion. When the cutting fluid is sprayed onto the cutting surface, it generates a large amount of foam due to impact and splashing. This foam, mixed with an oil film, can trap fine metal chips. Current centralized settling tanks are simply shell containers that collect waste cutting fluid and allow metal chips to settle naturally before the liquid is passed to subsequent equipment for chip removal and filtration. However, the natural settling effect is too slow, especially when the foam and oil film are mixed together, making it difficult for a large number of fine chips to settle. Furthermore, the natural defoaming process is slow. Since the cutting fluid needs to be recycled, it is not feasible to use large amounts of defoamer for rapid defoaming, as this would significantly increase the settling time and cause the foam to carry even more metal chips into subsequent equipment, increasing the processing pressure. Summary of the Invention
[0005] The purpose of this invention is to provide a waste cutting fluid separation and iron filings removal device. This device utilizes inclined plates to divide the fluid into multiple thin streams, increasing the settling area and shallowing the flow layer to enhance the overall rapid sedimentation effect. Within the narrow space between the inclined plates, the defoaming net repeatedly shakes under the action of the swaying connection, rapidly breaking the surface tension of the foam and oil film through division and friction. The metal filings released by the foam bursting quickly sink under the action of the inclined plates, achieving the purpose of rapidly eliminating foam and settling metal filings, thus solving the problems mentioned in the background art.

[0011] As a further embodiment of the present invention: a directional guide plate is fixedly provided on the side of the L-shaped flow buffer plate near the flow channel. The directional guide plate is inclined downward on the side away from the L-shaped flow buffer plate. The lower edge of the directional guide plate is located in the middle of the biaxial crushing roller, and is used to guide the debris to the middle of the biaxial crushing roller.
[0012] As a further embodiment of the present invention: observation windows are provided on both sides of the settling tank, and the observation windows are located near the lower side of the inclined plate; a manifold is fixedly provided on the side of the settling tank corresponding to the overflow outlet, and a drain outlet is provided in the middle of the lower side of the manifold.
[0013] As a further embodiment of the present invention: the lower side of the L-shaped flow buffer plate is symmetrically fixedly provided with side plates, the inclined plate is fixedly provided between the side plates, and the upper side of the L-shaped flow buffer plate near the inner wall of the settling tank is bent upward with folded edge plates. The folded edge plates are bolted to the settling tank, which facilitates the removal of the L-shaped flow buffer plate together with the inclined plate and the defoaming net from the inside of the settling tank, making it easy to disassemble and maintain the whole.

[0019] Compared with the prior art, the beneficial effects of the present invention are: Compared to the simple natural gravity settling in current settling tanks, this invention uses inclined plates to divide the fluid into multiple thin streams. By increasing the settling area and making the flow layer shallower, the overall rapid settling effect is enhanced. Each thin stream is blocked by the inclined plates and does not affect the others. In the narrow space between the inclined plates, the defoaming net repeatedly shakes under the action of the shaking connection. Through the action of division and friction, the surface tension of the foam and oil film is quickly broken. The metal debris released by the foam bursting settles quickly under the action of the inclined plates, achieving the purpose of quickly eliminating foam and settling metal debris. This greatly reduces the settling time and avoids foam carrying a large amount of metal debris into subsequent equipment, effectively reducing the pressure of subsequent processing.

[0021] 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 skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Example 1 Please see Figures 1-5The present invention provides a technical solution comprising: a settling tank 1, an L-shaped flow buffer plate 2 disposed on the inner side of the settling tank 1, a flow channel existing between one side of the L-shaped flow buffer plate 2 and the inner wall of the settling tank 1, inclined plates 3 fixedly disposed at equal intervals on the lower side of the L-shaped flow buffer plate 2, the inclined plates 3 all inclined downwards towards the side away from the flow channel, an overflow outlet 5 opened on the side of the settling tank 1 away from the flow channel, the overflow outlet 5 being disposed on the upper side of the inclined plates 3, a defoaming mechanism 6 disposed on the lower side of the L-shaped flow buffer plate 2, the defoaming mechanism 6 comprising a swaying connection part and a defoaming net 69, the defoaming net 69 being disposed on the lower side of the swaying connection part, the defoaming net 69 being disposed parallel to each other between the inclined plates 3, the swaying connection part being used to drive the defoaming net 69 to sway horizontally, the defoaming net 69 being used to sway horizontally between the inclined plates 3, the swaying connection part comprising a swaying... The settling tank 1 is equipped with a rocking rod 61, a crossbar 62, an insert rod 63, a motor 64, an eccentric disc 65, and a connecting rod 66. The rocking rod 61 is symmetrically arranged on the upper side of the inclined plate 3. The crossbar 62 is fixedly mounted on the upper side of the rocking rod 61 near the overflow outlet 5. The insert rod 63 is arranged in the middle of the side of the crossbar 62 and extends through to the outside of the settling tank 1. The motor 64 is fixedly mounted on the side of the settling tank 1 near the insert rod 63. The output end of the motor 64 is fixedly connected to the eccentric disc 65. The connecting rod 66 is connected to the insert rod 63 through a transmission. The two ends of the connecting rod 66 are rotatably connected to the insert rod 63 and the eccentric disc 65, respectively. The connecting rod 66 and the eccentric disc 65 are eccentrically connected. The L-shaped flow buffer 2 is fixedly arranged on the upper inner side of the settling tank 1. The L-shaped flow buffer 2 is inclined downward towards the liquid flow channel.
[0023] The workflow and principle of this embodiment: The cutting fluid mixed with metal chips enters from the opening on the upper side of the settling tank 1. The L-shaped flow buffer 2 forms a flow buffer zone. The cutting fluid flows into the flow channel along the L-shaped flow buffer 2, which can prevent the cutting fluid from falling directly into the inner side of the settling tank 1 and reduce the impact of the incoming fluid on the settling of metal chips. After that, the cutting fluid reaches the bottom of the inner side of the settling tank 1. The cutting fluid collected at the bottom of the inner side of the settling tank 1 begins to settle naturally due to gravity. As the cutting fluid increases, the cutting fluid level rises continuously. Finally, the liquid level covers the inclined plate 3. The cutting fluid can be discharged through the overflow outlet 5. At this time, the cutting fluid maintains a continuous flow path from the L-shaped flow buffer 2 to the overflow outlet 5. When the cutting fluid passes between the inclined plates 3, the inclined plates 3 can divide the cutting fluid into multiple thin fluids. According to the shallow pool theory, the shallower the water layer and the larger the sedimentation area, the faster the particulate impurities in the liquid settle. The inclined plates 3 can cut the fluid and increase the contact area at the same time, thereby accelerating the natural sedimentation rate of metal chips in the cutting fluid.
[0024] Because the cutting fluid contains emulsion components, when it is sprayed out to wash the workpiece and equipment, it generates a large amount of foam. The foam and oil will encapsulate fine debris. Due to the upward movement of air, the rapid sedimentation of these foam-encapsulated debris will be affected. At this time, the shaking connection will cause the defoaming net 69 to shake horizontally repeatedly within the inclined plate 3. The thin fluid between the inclined plates 3 flows upward. The horizontal shaking of the defoaming net 69 can quickly separate the foam in the fluid using the mesh. At the same time, the fluid flow rubs against the rough mesh surface of the defoaming net 69, and the fluid has already been separated by the inclined plate 3. The fluid is divided into multiple thin streams, each independent of the others. Within the narrow space between the inclined plates 3, the defoaming net 69 can work rapidly and repeatedly, quickly breaking down the tension of the foam and oil film. The released metal debris settles rapidly under the action of the inclined plates 3, achieving the purpose of quickly eliminating foam and settling metal debris. The cutting fluid, after defoaming and debris settling, is discharged through the overflow port 5 and can be connected to subsequent processing equipment. Using methods such as magnetic attraction and filtration, the remaining fine debris is further removed and ultimately recycled.
[0025] The following is a supplementary explanation of the operation process of the swaying connection: Motor 64 starts and drives the eccentric disk 65 to rotate in one direction. The eccentric disk 65 is eccentrically connected to the connecting rod 66. When it rotates, it will repeatedly push and pull the insert rod 63 through the connecting rod 66. The insert rod 63 pushes and pulls the crossbar 62. The crossbar 62 drives the defoaming net 69 to repeatedly move and sway between the inclined plates 3 through the swaying rod 61.
[0026] The inclined plate 3 divides the fluid into multiple thin streams, increasing the overall rapid sedimentation effect by increasing the settling area and making the flow layer shallower. Each thin stream is blocked by the inclined plate 3 and does not affect the others. In the narrow space between the inclined plates 3, the defoaming net 69 shakes repeatedly under the action of the shaking connection. Through the action of division and friction, it quickly destroys the surface tension of the foam and oil film. The metal debris released by the foam bursting settles quickly under the action of the inclined plate 3, achieving the purpose of quickly eliminating foam and settling metal debris.
[0027] In order to avoid the metal scraps from squeezing the sedimentation space too quickly as the accumulation increases during the sedimentation collection of metal scraps, the following optimizations are made: a scrap collection box 4 is fixedly installed at the bottom of the sedimentation tank 1, a scrap discharge port is opened on one side of the scrap collection box 4, a cover is fitted on the outside of the scrap discharge port, and the bottom of the inner side of the sedimentation tank 1 is an inclined surface that slopes toward the scrap collection box 4.
[0028] The settled debris will fall into the debris collection box 4 for collection. The debris collection box 4 can reduce the accumulation position of debris and prevent debris from accumulating directly inside the settling tank 1. It can also prevent the debris from being squeezed into the settling space as the accumulation increases. The cover can be opened periodically to discharge debris and residual waste liquid. The debris at the bottom of the inner side of the settling tank 1 will be guided into the debris collection box 4 along the slope.
[0029] In order to quickly determine the amount of metal debris deposited during the sedimentation and collection of metal scrap, the following structural supplement is made: observation windows are provided on both sides of the sedimentation tank 1, and the observation windows are located close to the lower side of the inclined plate 3.
[0030] The observation window is positioned close to the inclined plate 3. When the accumulated debris can be clearly observed through the observation window, it means that the accumulated debris is close to the observation window. At this time, it is necessary to clean the debris inside the settling tank 1 and the debris collection box 4.
[0031] To ensure a stable discharge of the cutting fluid during the discharge process, the following structural supplement is provided: a manifold 8 is fixedly installed on the side of the settling tank 1, corresponding to the overflow port 5, and a drain port 9 is installed in the lower middle part of the manifold 8.
[0032] The manifold 8 can form a stable overflow zone. The cutting fluid discharged from the overflow port 5 will first gather at the bottom inside the manifold 8, ensuring that the flow rate of the cutting fluid discharged from the drain port 9 is relatively stable.
[0033] Example 2 Please see Figure 1 and Figure 3 Based on Embodiment 1, the present invention provides a technical solution: a dual-shaft crushing roller 7 is rotatably arranged between the liquid flow channels inside the settling tank 1, a motor 2 is arranged on the side of the settling tank 1 corresponding to the dual-shaft crushing roller 7, the height of the dual-shaft crushing roller 7 is not lower than the overflow trough opening 5, a directional guide plate 22 is fixedly arranged on the side of the L-shaped flow buffer plate 2 near the liquid flow channel, the directional guide plate 22 is inclined downward on the side away from the L-shaped flow buffer plate 2, and the lower edge of the directional guide plate 22 is located in the middle position of the dual-shaft crushing roller 7.
[0034] The debris generated during cutting includes shredded wire and clumps of shredded wire. These clumps are fluffy and take up a lot of space. The dual-shaft crushing roller 7 is driven by a motor and can tear and break up the shredded wire in the cutting fluid to reduce the space occupied by the debris. A directional guide plate 22 is set to guide the debris to the middle of the dual-shaft crushing roller 7, so that the dual-shaft crushing roller 7 can quickly process the debris. The height of the dual-shaft crushing roller 7 is not lower than the overflow trough 5 to prevent the dual-shaft crushing roller 7 from being directly submerged in the liquid surface, thus avoiding disturbance to the normal settling of metal debris during crushing. In addition, the dual-shaft crushing roller 7 can further slow down the flow and reduce the impact force of the fluid falling.
[0035] Example 3 Please see Figure 4 and Figure 5Based on Embodiment 1, the present invention provides a technical solution: the lower side of the L-shaped flow buffer plate 2 is symmetrically fixed with side plates 21, the inclined plate 3 is fixedly disposed between the side plates 21, and the upper side of the L-shaped flow buffer plate 2 near the inner side wall of the settling tank 1 is bent upward with folded edge plates 23, and the folded edge plates 23 are bolted to the settling tank 1.
[0036] By disconnecting the folded edge plate 23 from the settling tank 1, and disconnecting the linkage rod 66 from the insertion rod 63 (the linkage rod 66 and the insertion rod 63 are a common detachable rotatable connection), and simultaneously disconnecting the threaded connection between the insertion rod 63 and the crossbar 62, the L-shaped flow buffer plate 2, together with the inclined plate 3 and the defoaming net 69, can be removed from the inside of the settling tank 1 as a whole, facilitating overall disassembly and maintenance.
[0037] Meanwhile, considering the stability issue when the shaking rod 61 drives the defoaming net 69 to shake, the following optimization is made: the shaking rod 61 is directly pressed and placed on the upper side of the inclined plate 3.
[0038] The inclined plate 3 can support the rocking rod 61, thereby making the translation of the defoaming net 69 driven by the rocking connection more stable.
[0039] As the defoaming net 69 is used continuously, it needs to be replaced due to problems such as aging, debris penetration and mesh blockage. Considering the convenience of replacing the defoaming net 69, the following structural optimization is made: clamping rods 68 are provided on both sides of the defoaming net 69, and the upper end of the clamping rods 68 is fixedly connected to the rocking rod 61.
[0040] The two sides of the defoaming net 69 can slide into the clamping rod 68. The clamping rod 68 clamps the two sides of the defoaming net 69. When it needs to be replaced, the defoaming net 69 can be pulled out directly and a new defoaming net 69 can be clamped and slid in. In order to increase the clamping stability of the clamping rod 68 on the defoaming net 69, a bolt structure can also be screwed into the side of the clamping rod 68 to press the defoaming net 69.
[0041] To address the stability issue when the insertion rod 63 is pulled out, the following structural optimizations are made: auxiliary rods 67 are symmetrically arranged on both sides of the insertion rod 63 on the side of the settling tank 1. The auxiliary rods 67 are inserted into the inner side of the settling tank 1 and threadedly connected to the crossbar 62.
[0042] The auxiliary rod 67 can restrict the crossbar 62 on both sides, increase the stability of the insertion rod 63 during pulling, and increase the stability of the crossbar 62 during swaying.
[0043] In view of the protection of motor 64 during operation, the following structural optimization is made: a protective shell is fixedly installed on the side of the settling tank 1 outside the motor 64 and auxiliary rod 67. The side of the protective shell away from the settling tank 1 is open, and a rotating plate is rotatably installed at the opening.
[0044] It can provide protection and isolation on the outside, preventing interference from external factors that could cause the shaking connection to malfunction.
