Description

Technical Field

[0001] This invention relates to the technical field of machine tool auxiliary structures, and in particular to a coolant treatment device for automatically separating impurities. Background Technology

[0002] As the core of modern manufacturing equipment, CNC machine tools are widely used in key fields such as aerospace, precision molds, medical devices, and energy equipment due to their excellent automatic machining capabilities and high-precision machining. In these demanding production scenarios, the cutting process generates a large amount of heat and chips. To ensure machining accuracy, extend tool life, maintain stable equipment operation, and improve workpiece surface quality, cutting coolant plays an indispensable role. It needs to be continuously and in large quantities sprayed onto the contact area between the tool and the workpiece for cooling, lubrication, cleaning (washing away chips), and rust prevention.

[0003] Since the coolant needs to be recycled, it is necessary to separate the coolant from the chips. However, traditional separation methods can only filter and separate larger chips, and cannot separate fine chips and impurities. As a result, such impurities will enter the cooling system with the coolant, which can easily lead to pipe blockage, pump damage, and other problems. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a coolant treatment device for automatically separating impurities, the specific technical solution of which is as follows: The present invention provides an automatic coolant treatment device for separating impurities, comprising a treatment chamber and a main shaft installed inside the treatment chamber. A plurality of partitions are horizontally and equally spaced on the main shaft. Each partition includes two mating plates and a magnetic plate. The two mating plates form a structure with an internal cavity. The magnetic plate is located inside the cavity and is used to provide a magnetic field for the area between two adjacent partitions. The treatment chamber is equipped with an inlet pipe for water intake and an overflow pipe for drainage.

[0005] Furthermore, each of the mating pieces is provided with a convex ring on its inner circumference, and a support ring is provided between two convex rings. The magnetic plate is connected to the support ring, and the convex ring rotates on the support ring. The cavity formed by the two docking plates is an annular cavity coaxial with the main shaft, and the partition is located on one side of the annular cavity. The magnetic field generated by the magnetic plate covers the area of ​​the partition located below the liquid surface of the coolant. A slag discharge structure is provided between two adjacent partition plates.

[0006] Furthermore, two support frames are arranged opposite each other in the middle of the partition plate, and the two convex rings are slidably mounted on the support frames on the same side. The support frames are connected to the main shaft through support shafts, and the two support shafts are coaxial. The support shafts are rotatably mounted on the main shaft.

[0007] Furthermore, along the axis of the main shaft, the cross-sections of the two convex rings are on the same circle, and each of the convex rings is provided with teeth; A transmission column coaxial with the main shaft is inserted in the middle of several of the partitions. The transmission column meshes with the teeth on the convex ring to transmit power to the convex ring.

[0008] Furthermore, a movable plate is slidably disposed on the outer wall of the main shaft along the axis of the main shaft, and the movable plate is rotatably connected to each of the support rings through an inclined connecting plate.

[0009] Furthermore, each of the partitions located on both sides is provided with a spherical shell, and each spherical shell is provided with a spherical groove. The spherical shell slides within the spherical groove, and the spherical groove is fixed to the processing chamber.

[0010] Furthermore, an elongated opening is provided on the outer wall of the processing chamber; The slag discharge structure includes a collection hopper inclined between the two partition plates and a scraper disposed on the collection hopper. The scraper is used to scrape impurities on the outer wall of the partition plates into the collection hopper. The output end of the collection bucket passes through the long opening and extends out.

[0011] Furthermore, the collecting hopper is movably disposed along the axis of the main shaft, and the collecting hopper is connected to the processing chamber via an elastic body.

[0012] The beneficial effects of this invention are as follows: By using a series of partitions arranged in a straight line, a narrow channel for coolant to pass through can be formed between two adjacent partitions, thereby reducing the distance between impurities in the coolant and the outer wall of the partition. Combined with the magnetic attraction of the partitions to impurities, impurities can be quickly adsorbed onto the partitions, achieving the separation effect between impurities and coolant. This prevents small particulate impurities from entering the cooling system and damaging the system structure, ensuring the long-term and stable operation of the cooling system.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0019] like Figures 1 to 7 As shown, an automatic impurity separation coolant treatment device of the present invention includes a treatment chamber 1 and a main shaft 4 installed inside the treatment chamber 1. A plurality of partitions 5 are arranged horizontally at equal intervals on the main shaft 4. Each partition 5 includes two mating plates 6 and a magnetic plate 7. The two mating plates 6 form a structure with a cavity inside. The magnetic plate 7 is located inside the cavity and is used to provide a magnetic field for the area between two adjacent partitions 5. The treatment chamber 1 is equipped with an inlet pipe 2 for water intake and an overflow pipe 3 for drainage.

[0020] In this invention, the main shaft 4 is horizontally positioned within the processing chamber 1, and the main shaft 4 supports several partitions 5. The partitions 5 are arranged at equal intervals on the main shaft 4, allowing the coolant to flow through the area between several adjacent partitions 5. This allows small particulate impurities in the coolant to approach the outer wall of the partition 5, making it easier to use the magnetic field generated by the magnetic plate 7 inside the partition 5 to adsorb the small particulate impurities onto the outer wall of the partition 5, thereby achieving impurity separation. This avoids situations where the distance between the small particulate impurities and the outer wall of the partition 5 is too far, resulting in a weak magnetic field effect on the small particulate impurities, or where the small particulate impurities cannot be adsorbed onto the partition 5 in time and are carried away by the water flow. The two mating plates 6 provide a sealed space for the magnetic plate 7 to prevent the magnetic plate 7 from directly contacting the coolant. The magnetic plate 7 is planar, with two magnetic poles on each side of its plane, and the magnetic poles of adjacent magnetic plates 7 correspond to each other; the shape of the processing chamber 1 corresponds to the shape of the partition plate 5, so as to... Figure 1 and Figure 2 For example, when the shape of the partition plate 5 is circular, the shape of at least the middle or lower part of the processing chamber 1 is arc-shaped to facilitate its use with the partition plate 5; When the coolant is processed, the coolant that has been initially filtered is introduced into the lower part of the processing chamber 1 through the inlet pipe 2. The coolant in the processing chamber 1 gradually increases and overflows through the overflow pipe 3. When the coolant in the processing chamber 1 passes through the area between two adjacent partitions 5, the magnetic field generated by the magnetic plate 7 adsorbs small particulate impurities in the coolant onto the surface of the partition 5, thereby separating them from the coolant. By using a series of partitions 5 arranged in a straight line, a narrow channel for coolant to pass through can be formed between two adjacent partitions 5, thereby reducing the distance between impurities in the coolant and the outer wall of the partition 5. Combined with the magnetic attraction of the partitions 5 to impurities, impurities can be quickly adsorbed onto the partitions 5, achieving the separation effect between impurities and coolant. This prevents small particulate impurities from entering the cooling system and damaging the system structure, ensuring the long-term and stable operation of the cooling system.

[0021] Furthermore, each of the mating pieces 6 has a protruding ring 8 on its inner circumference, and a support ring 9 is provided between two protruding rings 8. The magnetic plate 7 is connected to the support ring 9, and the protruding ring 8 rotates on the support ring 9. The cavity formed by the two docking plates 6 is an annular cavity coaxial with the main shaft 4, and the partition 5 is located on one side of the annular cavity. The magnetic field generated by the magnetic plate 7 covers the area of ​​the partition 5 below the liquid surface of the coolant. A slag discharge structure 17 is provided between two adjacent partition plates 5.

[0022] The coolant level in the processing chamber 1 can be located in the middle or lower part of the main shaft 4, so that a slag removal structure 17 can be set in the upper part of the main shaft 4, which can separate the slag removal structure 17 from the coolant. Since the convex ring 8 can rotate on the support ring 9, the partition 5 can rotate. For ease of use, the partition 5 can be circular, and the middle or lower part of the processing chamber 1 can be arc-shaped. Since the magnetic plate 7 provides a magnetic field to the part of the partition 5 below the liquid surface, there is no magnetic field around the part of the partition 5 above the liquid surface. When the partition 5 rotates, the partition 5 with adsorbed impurities can carry the impurities to the liquid surface. Since the impurities are removed from the magnetic field, they can easily fall off the partition 5 into the slag removal structure 17. As the partition 5 continues to rotate, the separated impurities can be continuously discharged, thereby preventing the accumulation of impurities on the partition 5. It should be noted that since different areas of the partition plate 5 have different functions, in order to avoid the mating piece 6 from directly contacting the magnetic plate 7 and making the entire mating piece 6 magnetic, the mating piece 6 needs to be made of non-magnetic material.

[0023] Furthermore, two support frames 10 are arranged opposite each other in the middle of the partition plate 5. The two convex rings 8 are slidably mounted on the support frame 10 on the same side. The support frame 10 is connected to the main shaft 4 through a support shaft 11, and the two support shafts 11 are coaxial. The support shaft 11 is rotatably mounted on the main shaft 4.

[0024] The support frame 10 can be bow-shaped. Both convex rings 8 pass through the inner wall of the support frame 10 and move. The support frame 10 slides in contact with the outer wall of the convex rings 8. Thus, the support frame 10 and the support shaft 11 can support the partition 5. Since the support shaft 11 can rotate on the main shaft 4, the partition 5 can be tilted relative to the axis of the main shaft 4, and the distance between two adjacent partitions 5 can be adjusted, which makes it convenient to adjust the thickness of the coolant that can pass between two adjacent partitions 5.

[0025] Furthermore, along the axial direction of the main shaft 4, the cross sections of the two convex rings 8 are on the same circle, and each of the convex rings 8 is provided with teeth; A transmission column 12, coaxial with the main shaft 4, is inserted in the middle of several partitions 5. The transmission column 12 meshes with the teeth on the convex ring 8 to transmit power to the convex ring 8.

[0026] To provide rotational power to each partition 5, a gear meshing transmission method can be adopted between the transmission column 12 and the convex ring 8. When the transmission column 12 rotates, it will directly drive the convex ring 8 and the partition 5 to rotate. Since the partition 5 can tilt relative to the axis of the main shaft 4, in order to ensure that the transmission column 12 always meshes with the teeth on the convex ring 8, the cross sections of the two convex rings 8 need to be on the same circle. At the same time, since the distance between the contact position of the convex ring 8 and the axis of the main shaft 4 changes when the partition 5 tilts, the position of the transmission column 12 needs to move synchronously to avoid the transmission column 12 blocking the convex ring 8 and preventing the partition 5 from tilting. Specifically, the transmission column 12 can be made of a toothed flexible shaft or a rigid material. When the transmission column 12 is made of a rigid material, it is allowed to move closer to or further away from the main shaft 4. In this case, in order to ensure that the transmission column 12 always contacts the convex ring 8, auxiliary structures such as connecting rings and elastic bodies can be set for the transmission column 12, and the transmission column 12 can be connected to a motor.

[0027] Furthermore, a movable plate 13 is slidably disposed on the outer wall of the main shaft 4 along the axial direction of the main shaft 4, and the movable plate 13 is rotatably connected to each of the support rings 9 through an inclined connecting plate 14.

[0028] Since the movable plate 13 slides on the main shaft 4, when the movable plate 13 is stationary, it can restrict each support ring 9 through the connecting plate 14, and the support ring 9 and the magnetic plate 7 cannot move. However, when the movable plate 13 slides on the main shaft 4, it can push the support ring 9 to move through the connecting plate 14. At this time, the support ring 9 can drive the partition 5 to tilt, and the support shaft 11 rotates on the main shaft 4. Thus, each magnetic plate 7 can be restricted by the movable plate 13 and the connecting plate 14, and the tilt angle of the partition 5 can be easily adjusted. The movable plate 13 and the main shaft 4 can be fastened together by bolts.

[0029] Furthermore, each of the two partitions 5 located on both sides of the partitions 5 is provided with a spherical shell 15, and each spherical shell 15 is provided with a spherical groove 16, and the spherical shell 15 slides in the spherical groove 16, and the spherical groove 16 is fixed to the processing chamber 1.

[0030] Since the baffle 5 needs to tilt, there needs to be sufficient space between the baffles 5 on both sides and the inner wall of the processing chamber 1. The existence of this space will cause the coolant to flow through, which will result in some coolant not being effectively treated. By using the arrangement of the spherical shell 15 and the spherical groove 16, when the baffle 5 tilts, the spherical shell 15 moves synchronously in the spherical groove 16, which can block the space. The center of the spherical shell 15 and the center of the spherical groove 16 both coincide with the center of the corresponding baffle 5.

[0031] Furthermore, an elongated opening 20 is provided on the outer wall of the processing chamber 1; The slag discharge structure 17 includes a collection hopper 18 inclinedly disposed between the two partition plates 5 and a scraper 19 disposed on the collection hopper 18. The scraper 19 is used to scrape the impurities on the outer wall of the partition plate 5 into the collection hopper 18. The output end of the collecting hopper 18 passes through the elongated opening 20 and extends outwards.

[0032] By using the contact between the scraper 19 and the outer wall of the partition plate 5, impurities adsorbed on the outer wall of the partition plate 5 can be scraped off, thus facilitating the timely separation of impurities and preventing them from depositing on the partition plate 5 or falling back into the coolant due to the impurities moving away from the magnetic field. Because the partition plate 5 is tilted, the scraper 19 is allowed to contact the outer wall of the partition plate 5, while the collection hopper 18 is located below the scraper 19 and is separated from the partition plate 5, thus preventing the collection hopper 18 from obstructing the impurities on the partition plate 5. This arrangement allows the width of the collection hopper 18 to be greater than the width of the scraper 19, thereby facilitating the collection of impurities scraped off by the scraper 19.

[0033] Furthermore, the collecting hopper 18 is movably disposed along the axis of the main shaft 4, and the collecting hopper 18 is connected to the processing chamber 1 via an elastic body 21.

[0034] Since both sides of the partition plate 5 can collect impurities and the partition plate 5 can be tilted to the left or right, the slag discharge structure 17 needs to be movable. In the idle state, the partition plate 5 is vertical, and the slag discharge structure 17 is located in the middle area between the two partition plates 5 and is separated from the partition plate 5. When working, the partition plate 5 tilts to one side, and the partition plate 5 contacts the slag discharge structure 17 and pushes the slag discharge structure 17 to move synchronously. The elastic body 21 undergoes elastic deformation, thereby ensuring that the slag discharge structure 17 abuts against the outer wall of the partition plate 5. When the partition plate 5 tilts to the other side, the slag discharge structure 17 is squeezed by the other partition plate 5, thereby facilitating the use of the slag discharge structure 17 with the outer walls of the two adjacent partition plates 5. The collection bucket 18 can be installed in the processing chamber 1 via a guide rail.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
