Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration equipment technology, and in particular to a cutting fluid filtration device. Background Technology
[0002] Cutting fluid plays a role in cooling, lubrication, cleaning and rust prevention during machining. Its cleanliness directly affects machining accuracy and equipment life. Therefore, an efficient cutting fluid filtration device is crucial. It can effectively remove metal chips, impurities and other contaminants from the cutting fluid, ensuring its recyclability.
[0003] Currently, common cutting fluid filtration devices intercept impurities by using a filter screen. The filter screen is installed in the flow path of the cutting fluid, and its pore size blocks impurities larger than the pores, thus filtering the cutting fluid. Some devices also employ centrifugal separation, using the centrifugal force generated by high-speed rotation to move denser impurities such as metal chips outwards, thereby separating them from the cutting fluid.
[0004] However, existing filtration devices have many shortcomings. Screen filtration is difficult to effectively remove fine particles and adsorbent metal debris, resulting in insufficiently clean cutting fluid that cannot meet the requirements for recycling. Centrifugal separation equipment has high energy consumption and strict requirements for equipment sealing and stability, resulting in high maintenance costs. Therefore, there is an urgent need for a cutting fluid filtration device to solve the above problems. Utility Model Content
[0005] To overcome the shortcomings of the prior art, this utility model provides a cutting fluid filtration device, which solves the technical problem that existing filtration devices are unable to remove small particles and adsorbent metal shavings, resulting in insufficiently clean cutting fluid and high filtration costs.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0007] A cutting fluid filtration device, comprising:
[0008] The box has an opening at the top and a top cover. The top cover is placed over the opening at the top of the box. The box has a cavity inside. The side wall of the box has a liquid inlet and a liquid outlet, both of which are connected to the cavity.
[0009] A set of baffle assemblies, corresponding to the flow direction of the cutting fluid, are spaced apart in the cavity. The baffle assembly includes a first baffle and a second baffle. The first baffle and the second baffle are arranged sequentially and spaced apart in the flow direction of the cutting fluid. The upper end of the second baffle is higher than the upper end of the first baffle. The bottom of the first baffle extends to the bottom wall of the cavity.
[0010] A magnetic suction component, used to attract metal debris in the cutting fluid;
[0011] The filter assembly includes a first filter element and a second filter element, wherein the first filter element and the second filter element are used to filter the cutting fluid when it enters the inlet and when it exits the outlet.
[0012] Based on the above structure, the principle of the cutting fluid filtration device is as follows: When cutting fluid needs to be filtered, firstly, the cutting fluid to be filtered flows into the tank through the inlet via a pipe. The cutting fluid passes through the first filter component to remove large particles of impurities and enters the cavity. Then, as the cutting fluid flows through the baffle assembly, it first contacts the first baffle. Because the bottom of the first baffle extends to the bottom wall of the cavity, the cutting fluid cannot flow through the bottom of the first baffle and changes its flow direction, overflowing from the top of the first baffle. During this process, the flow rate of the cutting fluid decreases due to the change in flow direction. Simultaneously, some larger particles of impurities begin to settle at the bottom of the tank due to inertia and gravity. Next, the cutting fluid continues to flow forward, at which point it contacts the second baffle. Because the top of the second baffle is higher than the top of the first baffle, there is a gap between its bottom and the bottom wall of the cavity, forming a flow channel. After the cutting fluid flows out of the flow channel, its flow rate is further reduced to facilitate the sedimentation of impurities. It then enters the next set of baffle assembly areas, repeating the above process. During this process, the magnetic adsorption component uses a magnetic field to adsorb fine metal particles such as iron filings and steel chips from the cutting fluid. When the cutting fluid enters the area between the baffle assembly and the outlet, a second filter component is located near the outlet. This component performs fine filtration on the cutting fluid after it has passed through the first and second baffles and been magnetically adsorbed by the magnetic adsorption component, before discharging it from the outlet. The cutting fluid filtration is complete. The filtration device adopts a multi-stage, progressive filtration design, effectively removing impurities from the cutting fluid through a combination of blocking, guiding, slowing, sedimentation, magnetic adsorption, and fine filtration. The multi-stage baffle assembly design is simple in structure, and its use, manufacturing, and maintenance costs are far lower than those of centrifugal separators.
[0013] Furthermore, in a cutting fluid filtration device of this application, the outer bottom of the housing is provided with a bottom shell, which is detachably installed at the bottom of the housing. The bottom shell includes a sedimentation tank, which is connected to the cavity, and the side of the first baffle is in contact with the inner wall of the sedimentation tank. As a preferred embodiment of this application, in a cutting fluid filtration device, the bottom shell is used to collect metal debris during the cutting fluid filtration process, and the side of the first baffle is in contact with the inner wall of the sedimentation tank to ensure that the cutting fluid can only overflow from the top of the first baffle; the detachable design of the bottom shell facilitates cleaning of the inside of the sedimentation tank.
[0014] Furthermore, in a cutting fluid filtration device of this application, a first sealing element is provided at the contact point between the first partition and the sedimentation tank. As a preferred embodiment of this application, the first sealing element in the cutting fluid filtration device of this application is used to prevent the cutting fluid from bypassing the partition assembly and flowing directly from the contact point between the first partition and the sedimentation tank, avoiding the problem of "filtration short circuit" and ensuring the filtration effect of the device.
[0015] Furthermore, in a cutting fluid filtration device of this application, an inclined plate is provided at the connection between the housing and the bottom shell, the inclined plate being positioned towards the sedimentation tank, and a second sealing element is provided at the upper end of the bottom shell, the second sealing element being positioned circumferentially along the bottom shell. As a preferred embodiment of this application, in a cutting fluid filtration device, the inclined plate is used to guide sediment in the cutting fluid smoothly from the cavity into the sedimentation tank below, and to reduce sediment accumulation at the connection; the second sealing element is used to prevent cutting fluid leakage from the connection between the bottom shell and the inclined plate.
[0016] Furthermore, in a cutting fluid filtration device of this application, a protrusion is provided on the bottom wall of the sedimentation tank, and the magnetic attraction component includes a magnet ring, which is sleeved on the protrusion. As a preferred embodiment of this application, in a cutting fluid filtration device of this application, the protrusion is used for the installation and positioning of the magnet ring, preventing the magnet ring from shifting and ensuring its stable adsorption of metal debris.
[0017] Furthermore, in a cutting fluid filtration device of this application, the first filter element is disposed within a cavity and located between the inlet and a first partition plate near the inlet. The first filter element includes: a barrel body, filter holes on the side wall of the barrel body, the filter holes being spaced apart along the circumference and axial direction of the barrel body, a dense metal mesh covering the outer side of the barrel body, a first mounting plate between the inlet and the second partition plate near the inlet, the first mounting plate extending horizontally to the second partition plate near the inlet and the inner wall of the housing, the second partition plate extending vertically to the upper end of the first mounting plate, and the barrel body being detachably mounted on the side of the first mounting plate away from the top cover. As a preferred embodiment of this application, a cutting fluid filtration device is provided. The cutting fluid flows in from the inlet and enters the upper part of the first mounting plate, then enters the interior of the barrel. It is first initially filtered through filter holes on the side wall of the barrel to intercept larger particles of impurities, and then finely filtered through a dense metal mesh covering the outside of the barrel to further remove tiny particles, leaving the impurities inside the barrel. The design of the second baffle extending vertically to the upper part of the first mounting plate prevents the cutting fluid from flowing around the first filter component from the upper part of the first mounting plate, ensuring filtration efficiency. The detachable design of the first filter component facilitates its installation, disassembly, and cleaning.
[0018] Furthermore, in a cutting fluid filtration device of this application, the second filter component is disposed within a cavity and located between the outlet and a second partition near the outlet. The second filter component includes: a filter cartridge with elongated filter holes on its side wall, the elongated filter holes being arranged in a circumferential array along the filter cartridge and extending axially along the filter cartridge; filter paper covering the outer side of the filter cartridge; a second mounting plate between the outlet and the second partition near the outlet; the second mounting plate extending horizontally to the second partition near the outlet and the inner wall of the housing; mounting holes on the second mounting plate; the filter cartridge disposed within the mounting holes; an extension at the upper end of the filter cartridge extending radially along the filter cartridge; and when the filter cartridge is mounted on the second mounting plate, the extension is in vertical contact with the upper surface of the second mounting plate. As a preferred embodiment of this application, a cutting fluid filtration device is provided, wherein the filter cartridge extends vertically downward to below the cutting fluid surface, and the long filter holes and filter paper work together to further filter the cutting fluid. The clean cutting fluid enters the filter cartridge and is discharged from the outlet through a suction device (not shown); the particulate impurities intercepted by the long filter holes and filter paper settle at the bottom of the housing under the action of gravity; the extension is used to limit the filter cartridge, so that the filter cartridge is positioned on the second mounting plate.
[0019] Furthermore, in a cutting fluid filtration device of this application, a pair of inspection ports are provided on the side wall of the housing. These inspection ports are respectively used for inspecting and repairing a first filter component and a second filter component. A pair of sealing covers are provided on the outer side of the housing, and these sealing covers are respectively installed over the corresponding inspection ports. As a preferred embodiment of this application, when the first filter component and the second filter component need to be inspected and repaired, the sealing covers of the corresponding inspection ports can be opened to repair or replace the first filter component and the second filter component without disassembling the entire filtration device, thus improving maintenance efficiency.
[0020] Furthermore, in a cutting fluid filtration device of this application, a frame is provided on the outer side of the housing, the housing is mounted on the frame, and a set of casters and a set of adjustable bases are provided at the bottom of the frame. The casters and adjustable bases are all spaced apart along the circumference of the frame. As a preferred embodiment of this application, in a cutting fluid filtration device, the frame is used to support the housing; the casters allow the filtration device to be easily moved within the work area, and the movement of the filtration device is achieved by the rolling of the casters, improving the flexibility of the filtration device; the adjustable bases are used to adjust the height to keep the frame level when the ground is uneven, ensuring that the filtration device can work normally on different ground surfaces.
[0021] As can be seen from the above technical solution, this utility model has the following beneficial effects:
[0022] The purpose of this invention is to provide a cutting fluid filtration device. By setting a baffle assembly to change the flow direction of the cutting fluid to reduce the flow rate and promote the sedimentation of impurities, and with the help of a magnetic component to adsorb metal chips, the device removes large particles and small impurities through a dual filtration structure of a first filter component and a second filter component. At the same time, the device's sealing performance and ease of maintenance are improved by using a detachable bottom shell, seals, and inspection ports. Attached Figure Description

Detailed Implementation
[0029] like Figure 1 , 2 As shown in Figure 3, a cutting fluid filtration device includes:
[0030] The box 1 has an opening at the top and a cover 2. The cover 2 is placed over the opening at the top of the box 1. The box 1 has a cavity 10 inside. The side wall of the box 1 has a liquid inlet 11 and a liquid outlet 12. The liquid inlet 11 and the liquid outlet 12 are both connected to the cavity 10.
[0031] A set of baffle assemblies 3, corresponding to the flow direction of the cutting fluid, are spaced apart in the cavity 10. The baffle assembly 3 includes: a first baffle 31 and a second baffle 32. The first baffle 31 and the second baffle 32 are arranged sequentially and spaced apart in the flow direction of the cutting fluid. The upper end of the second baffle 32 is higher than the upper end of the first baffle 31. The bottom of the first baffle 31 extends to the bottom wall of the cavity 10.
[0032] Magnetic suction component 4, which is used to attract metal debris in the cutting fluid;
[0033] The filter assembly 5 includes a first filter element 51 and a second filter element 52, which are used to filter the cutting fluid when it enters the inlet 11 and when it is discharged from the outlet 12.
[0034] Based on the above structure, the principle of the cutting fluid filtration device is as follows: When cutting fluid needs to be filtered, firstly, the cutting fluid to be filtered flows into the housing 1 through the inlet 11 via a pipe. The cutting fluid passes through the first filter component 51 to remove large particulate impurities and enters the cavity 10. Then, when the cutting fluid flows through the baffle assembly 3, it first contacts the first baffle 31. Since the bottom of the first baffle 31 extends to the bottom wall of the cavity 10, the cutting fluid cannot flow through the bottom of the first baffle 31 and changes its flow direction, overflowing from the top of the first baffle 31. During this process, the flow rate of the cutting fluid decreases due to the change in flow direction. At the same time, some larger particulate impurities begin to settle at the bottom of the housing 1 due to inertia and gravity. Next, the cutting fluid continues to flow forward, at which point it will contact the first baffle assembly 3. The second partition 32 has a gap between its bottom and the bottom wall of the cavity 10 because its upper end is higher than the upper end of the first partition 31. This gap forms a flow channel. After the cutting fluid flows out of the flow channel, the flow rate of the cutting fluid is further reduced to facilitate the sedimentation of impurities. Then, it enters the area of the next set of partition assembly 3 and repeats the above process. In the above process, the magnetic adsorption component 4 uses a magnetic field to adsorb small metal particles such as iron filings and steel filings in the cutting fluid. When the cutting fluid enters the area between the partition assembly 3 and the outlet 12, the second filter component 52 is set near the outlet 12. After the cutting fluid has been guided by the first partition 31 and the second partition 32 and magnetically adsorbed by the magnetic adsorption component 4, it is finely filtered and discharged from the outlet 12. The cutting fluid filtration is completed. The set of baffle assemblies 3 consists of two units, which divide the cavity 10 into three chambers. The second filter element 52 is equipped with a suction device (not shown) to discharge the cutting fluid from the outlet 12. The filter device adopts a multi-stage, progressive filtration design, which effectively removes impurities from the cutting fluid by combining blocking, guiding, slowing down, settling, magnetic adsorption, and fine filtration. The design of the multi-stage baffle assembly 3 is simple in structure, and its use, manufacturing, and maintenance costs are far lower than those of centrifugal separation equipment.
[0035] In this embodiment, the outer bottom of the housing 1 is provided with a bottom shell 6, which is detachably installed at the bottom of the housing 1. The bottom shell 6 includes a sedimentation tank 60, which is connected to the cavity 10. The side of the first partition 31 is in contact with the inner wall of the sedimentation tank 60. The bottom shell 6 is used to collect metal debris during the cutting fluid filtration process. The side of the first partition 31 is in contact with the inner wall of the sedimentation tank 60 to ensure that the cutting fluid can only overflow from the top of the first partition 31. The detachable design of the bottom shell 6 facilitates cleaning of the inside of the sedimentation tank 60. The bottom shell 6 is connected to the housing 1 by bolts (not shown).
[0036] In this embodiment, as Figure 4As shown, a first sealing element 311 is provided at the contact point between the first partition 31 and the sedimentation tank 60. The first sealing element 311 is used to prevent cutting fluid from bypassing the partition assembly 3 and flowing directly from the contact point between the first partition 31 and the sedimentation tank 60, avoiding the problem of "filtration short circuit" and ensuring the filtration effect of the device. The first sealing element 311 is a rubber sealing strip.
[0037] In this embodiment, as Figure 5 As shown, an inclined plate 13 is provided at the connection between the housing 1 and the bottom shell 6. The inclined plate 13 is positioned towards the sedimentation tank 60. A second sealing element 61 is provided at the upper end of the bottom shell 6, and the second sealing element 61 is arranged circumferentially along the bottom shell 6. The inclined plate 13 is used to guide the sediment in the cutting fluid to flow smoothly from the cavity 10 into the sedimentation tank 60 below, and to reduce the accumulation of sediment at the connection. The second sealing element 61 is used to prevent the cutting fluid from leaking from the connection between the bottom shell 6 and the inclined plate 13. The second sealing element 61 is a rubber sealing strip.
[0038] In this embodiment, the bottom wall of the sedimentation tank 60 is provided with a protrusion 601, and the magnetic attraction component 4 includes a magnet ring 41, which is sleeved on the protrusion 601. The protrusion 601 is used for the installation and positioning of the magnet ring 41, preventing the magnet ring 41 from shifting and ensuring its stable adsorption of metal debris. The bottom wall of the sedimentation tank 60 is provided with three protrusions 601, each corresponding to a chamber, and correspondingly, three magnet rings 41 are sleeved on the corresponding protrusions 601; in other embodiments, the magnet rings 41 are installed on the outer bottom of the bottom shell 6.
[0039] In this embodiment, the first filter component 51 is disposed in the cavity 10. The first filter component 51 is located between the liquid inlet 11 and the first partition 31 on the side near the liquid inlet 11. The first filter component 51 includes: a barrel body 511. The side wall of the barrel body 511 is provided with filter holes 510. The filter holes 510 are spaced apart along the circumference and axial direction of the barrel body 511. The outer side of the barrel body 511 is covered with a dense metal mesh 512. A first mounting plate 7 is provided between the liquid inlet 11 and the second partition 32 on the side near the liquid inlet 11. The first mounting plate 7 extends horizontally to the second partition 32 on the side near the liquid inlet 11 and the inner wall of the box body 1. The second partition 32 extends vertically to the upper end of the first mounting plate 7. The barrel body 511 is detachably mounted on the side of the first mounting plate 7 away from the upper cover 2. After the cutting fluid flows in through the inlet 11, it enters the upper part of the first mounting plate 7, and then enters the interior of the tank 511. It first undergoes preliminary filtration through the filter holes 510 on the side wall of the tank 511, intercepting larger particles of impurities. Then, it undergoes fine filtration through the dense metal mesh 512 covering the outside of the tank 511, further removing smaller particles. Impurities remain inside the tank 511. The design of the second baffle 32 extending vertically to the upper part of the first mounting plate 7 prevents the cutting fluid from flowing around the first filter element 51 from the upper part of the first mounting plate 7, ensuring filtration efficiency. The detachable design of the first filter element 51 facilitates its installation, removal, and cleaning. The upper opening of the tank 511 is threaded to the first mounting plate 7; the dense metal mesh 512 is made of stainless steel.

The upper end of the filter cartridge 521 is provided with an extension 523. The extension 523 extends radially along the filter cartridge 521. When the filter cartridge 521 is installed on the second mounting plate 8, the extension 523 is in vertical contact with the upper end surface of the second mounting plate 8. The filter cartridge 521 extends vertically downward to below the cutting fluid surface. The long filter holes 520 and the filter paper 522 work together to further filter the cutting fluid. The clean cutting fluid enters the filter cartridge 521 and is discharged from the outlet 12 through a suction device (not shown). The particulate impurities intercepted by the long filter holes 520 and the filter paper 522 settle at the bottom of the housing 1 under the action of gravity. The extension 523 is used to limit the filter cartridge 521, so that the filter cartridge 521 is positioned on the second mounting plate 8.
[0041] In this embodiment, a pair of inspection ports 100 are provided on the side wall of the housing 1. These inspection ports 100 are used for inspecting and repairing the first filter component 51 and the second filter component 52, respectively. A pair of sealing covers 14 are provided on the outer side of the housing 1, and these covers 14 are respectively installed over the corresponding inspection ports 100.
