Description

Technical Field

[0001] The invention relates to the technical field of machine tool cutting fluid treatment, in particular to a machine tool oil-water separation device and a use method thereof. Background Art

[0002] As we all know, cutting fluid is used in metal cutting processes such as turning, milling, drilling and other operations. It mainly plays the role of cooling and lubrication. A large amount of heat will be generated between the tool and the workpiece during the cutting process. The cutting fluid can absorb and take away this heat to prevent the tool and workpiece from being damaged due to overheating. At the same time, it reduces the wear rate of the tool and improves the processing accuracy and surface quality. Due to production cost constraints, the cutting fluid is usually separated and filtered multiple times and then reused multiple times.

[0003] After searching, a Chinese patent discloses an oil-water separation device and method for machine tools. Its application publication number is CN104841166B. This patent realizes automatic cleaning of oil-water separation and increases the utilization rate of floating oil. The efficiency of oil-water separation is improved, and manual cleaning is not required, which reduces costs. The added filter box improves the filtration accuracy, greatly improving the accuracy of recovered floating oil and cutting fluid.

[0004] When recovering liquid in the machine tool tank, a separation device is required. The existing technology has the following problems: most of them extract all the liquid in the machine tool tank to the separation device. These devices not only occupy the space that may be needed around the machine tool, but also the accumulated liquid is in a dynamic state during the extraction process. The internal solid impurities, floating oil and cutting fluid will be remixed together. The processing flow of some equipment also requires additional waiting and static, and the efficiency needs to be improved.

[0005] Based on the above-mentioned problems, we found that it is difficult for the existing machine tool oil-water separation device to avoid the above problems at the same time. Therefore, we proposed a device that can be directly installed inside the machine tool slot, which can effectively separate and discharge the solid impurities, floating oil and internal liquid in the machine tool slot under a less dynamic environment. Summary of the invention

[0006] 1. Technical issues to be solved

[0007] In view of the deficiencies in the prior art, the present invention provides a machine tool oil-water separation device and a method of using the same, which has the advantages of being able to be directly installed inside a machine tool slot and being able to effectively separate and discharge solid impurities, floating oil and internal liquid from the accumulated liquid in the machine tool slot in an environment with low dynamics.

[0008] (II) Technical solution

[0009] The above technical objectives of the present invention are achieved through the following technical solutions: A machine tool oil-water separation device comprises a machine tool slot, a partition is provided on the inner side of the machine tool slot, a separation component is provided on the inner side of the partition, and a floating component is provided on the inner side of the machine tool slot;

[0010] The partition plate comprises a plate cylinder portion, the front side and the rear side of the plate cylinder portion are both provided with flow grooves, the front side and the rear side of the plate cylinder portion are both fixedly connected with guide portions, and both sides of the plate cylinder portion are both fixedly connected with isolation portions;

[0011] The separation assembly includes a main shaft, which is arranged on the inner side of the plate cylinder, a connecting frame is fixedly connected to the outer side of the main shaft, a conical cylinder is fixedly connected to the outer side of the connecting frame, a spiral blade is fixedly connected to the outer side of the conical cylinder, the spiral blade is made of a metal fine mesh material, a matching plate is arranged on the outer side of the spiral blade, the inner side of the matching plate is in contact with the spiral blade, a mesh plate is fixedly connected to the left side of the plate cylinder, and an interception bucket is fixedly connected to the left side of the mesh plate;

[0012] The floating assembly comprises a floating frame, a floating plate is fixedly connected to the outside of the floating frame, a connecting frame is fixedly connected to the inside of the floating plate, a retaining frame is fixedly connected to the inside of the connecting frame, a suction head is fixedly connected to the inside of the retaining frame, and a floating oil pipe is fixedly connected to the bottom of the suction head;

[0013] A vertical plate is fixedly connected to the bottom of the right isolation part, a circular groove for use with a matching plate is provided on the inner side of the vertical plate, a slag plate is fixedly connected to the right side of the vertical plate, and a slag bucket is movably connected to the inner side of the slag plate.

[0014] By adopting the above technical scheme, a partition is set inside the machine tool slot to separate the space inside the machine tool slot and serve as a structural support. The cutting fluid generated during the turning process of the machine tool will directly fall into the inside of the machine tool slot. After a long period of accumulation, the cutting fluid floating on the top is directly in contact with the external environment, so it contacts impurities and deteriorates to produce floating oil. The floating frame of the floating component floats on the top of the cutting fluid through the floating plate, and the blocking frame connected to it by the connecting frame blocks the floating impurities on the surface from entering the interior. After the negative pressure of the floating oil pipe, the floating oil on the surface of the machine tool slot will be extracted from the suction head. During the cutting process, the cutting fluid is separated by the partition, so the liquid The cutting fluid will not fall directly to the bottom of the partition, but will flow into the plate cylinder through the flow groove along the isolation part and the top of the guide part. After entering the plate cylinder, the cutting fluid will fall into the conical part of the matching plate along the horizontal plane of the matching plate. When the main shaft rotates, it will drive the conical cylinder and the conical spiral blades to rotate along the inner side of the matching plate through the connecting frame. The impurities deposited at the bottom of the matching plate will be pushed by the spiral blades. Due to the low rotation speed, it is not easy to stir the cutting fluid. Impurities such as cutting chips will be pushed to the right side of the structure by the spiral blades and enter the right side of the vertical plate, and move along the slag plate to the slag bucket for direct recovery from the right side later.

[0015] The present invention is further configured as follows: a shaft frame is fixedly connected to the bottom of the right isolation part, the inner side of the shaft frame is rotatably connected to the main shaft, a vertical rod is fixedly connected to the bottom of the guide part, and the bottom of the vertical rod is fixedly connected to the machine tool slot.

[0016] By adopting the above technical solution, the main shaft can be easily supported by setting a shaft frame, and the vertical rod is used to support the guide part on the inner side of the machine tool groove to achieve a stable installation effect on the partition.

[0017] The present invention is further configured as follows: a transmission belt is movably connected to the inner side of the slag plate, and a shifting plate is fixedly connected to the surface of the transmission belt.

[0018] By adopting the above technical solution, a transmission belt is set up. When the transmission belt continues to move inside the slag plate, the shift plate on its surface will move along the moving path of the transmission belt, and shift the solid impurities on the surface of the slag plate from the slag plate to the inside of the slag bucket.

[0019] The present invention is further configured as follows: a transmission motor is fixedly connected to the front side of the slag plate, two transmission rollers are movably connected to the inner side of the transmission belt, and the output end of the transmission motor is fixedly connected to the front side of the right transmission roller.

[0020] By adopting the above technical solution, a transmission motor is provided to drive a transmission roller to rotate on the outer side of the slag plate, and the transmission belt connected thereto is driven to move by the transmission roller, thereby achieving the effect of driving the shifting plate to move.

[0021] The present invention is further configured as follows: a short frame is fixedly connected to the top of the blocking frame, and a shielding sheet is fixedly connected to the top of the short frame.

[0022] By adopting the above technical solution, a short frame is set to connect the baffle frame and the shielding sheet. The shielding sheet is located on the top of the baffle frame. When the liquid falls during the top cutting, it can be prevented from falling directly into the inside of the baffle frame and causing blockage.

[0023] The present invention is further configured as follows: the top of the guide portion is fixedly connected to a limiting rod, the outer side of the connecting frame is fixedly connected to a sliding sleeve, and the inner side of the sliding sleeve is slidably connected to the limiting rod.

[0024] By adopting the above technical solution, a limit rod is arranged in conjunction with a sliding sleeve, and the sliding sleeve slides on the outside of the limit rod to facilitate limiting the guide part. When the guide part moves along the liquid level surface through the floating plate, the sliding sleeve slides on the outside of the limit rod, which can enable the structure to maintain relative vertical movement and is not prone to horizontal displacement.

[0025] The present invention is further configured as follows: a force-bearing frame is fixedly connected to the inner side of the left isolation part, the inner side of the force-bearing frame is rotatably connected to the main shaft, a sealing bracket is fixedly connected to the left side of the inner side of the machine tool slot, a motor and a reducer are installed on the inner side of the sealing bracket, and the output ends of the motor and the reducer are fixedly connected to the main shaft.

[0026] By adopting the above technical solution, a force-bearing frame is provided to support the main shaft, and a sealing bracket is used to install the motor and the reducer while protecting them. The motor and the reducer are on the inner side of the sealing bracket to stably and slowly rotate the main shaft.

[0027] The present invention is further configured as follows: the outer side of the main shaft is rotatably connected to the intercepting bucket, a main pump is fixedly connected to the left side of the inner side of the machine tool slot, an oil pipe is fixedly connected to the input end of the main pump, and the side of the oil pipe away from the main pump is arranged at the bottom of the inner side of the intercepting bucket.

[0028] By adopting the above technical solution, a main pump is set up in conjunction with an oil pipe to extract and discharge the liquid between the interception bucket and the mesh plate. Due to the interception of the mesh plate, solid impurities will not be extracted, and the blocked solid impurities will be pushed by the rotating spiral blades.

[0029] The present invention is further configured as follows: an auxiliary pump is fixedly connected to the left side of the inner side of the machine tool slot, an input end of the auxiliary pump is fixedly connected to a hose, and the hose is fixedly connected to the floating oil pipe.

[0030] By adopting the above technical solution, by providing an auxiliary pump in combination with a hose, it is possible to connect the floating oil pipe through the hose, and to extract the floating oil on the liquid surface through the floating oil pipe and the suction head to discharge it.

[0031] A method for using a machine tool oil-water separation device comprises the following steps:

[0032] S1. The cutting fluid generated during the turning process of the machine tool will directly fall into the inside of the machine tool slot. Due to the separation of the partition, the liquid will not fall directly to the bottom of the partition, but will flow into the plate cylinder part through the flow groove along the guide of the isolation part and the top of the guide part. After a long period of accumulation, the cutting fluid floating on the top directly contacts the external environment, so it contacts impurities and deteriorates to produce floating oil;

[0033] S2. The floating frame of the floating assembly floats on the top of the cutting fluid through the floating plate, and the baffle frame connected to it through the connecting frame blocks the floating impurities on the surface from entering the interior. At the same time, the auxiliary pump is started to extract the floating oil on the surface of the machine tool slot from the suction head through the hose and the floating oil pipe;

[0034] S3. After entering the inner part of the plate cylinder, the cutting fluid will fall into the conical part of the matching plate along the horizontal surface of the matching plate. The main shaft of the separation component is driven by the motor and the reducer to rotate slowly. The conical cylinder and the conical spiral blade connected to it through the connecting frame rotate along the inner side of the matching plate. The impurities deposited at the bottom of the matching plate will be pushed by the spiral blade. Because of the low speed, it is not easy to stir the cutting fluid. The impurities such as cutting chips will be pushed to the right side of the structure and enter the right side of the vertical plate. The transmission motor drives the transmission belt through the transmission roller, and the paddle connected to it will paddle the impurities at the bottom of the slag plate and move them into the slag bucket;

[0035] S4. The main pump extracts the cutting fluid that has been filtered by the mesh plate and accumulated inside the intercepting bucket through the oil pipe, and discharges it to the outside of the structure for recycling. As the liquid level drops, the cutting fluid gradually fades from the slag plate, and the impurities are continuously pushed onto the slag bucket by the movement of the paddle plate. After the operation, it is taken out from the right side of the machine tool slot for processing.

[0036] (III) Beneficial effects

[0037] Compared with the prior art, the present invention provides a machine tool oil-water separation device and a method of using the same, which have the following beneficial effects:

[0038] The oil-water separation device for machine tools and the method for using the same, by arranging a partition plate inside the machine tool slot to separate the space inside the machine tool slot and serving as a structural support, the cutting fluid generated during the turning process of the machine tool will directly fall into the inside of the machine tool slot. After a long period of accumulation, the cutting fluid floating on the top will directly contact the external environment, so it will contact impurities and deteriorate to produce floating oil. The floating frame of the floating component floats on the top of the cutting fluid through the floating plate, and the blocking frame connected to the floating frame through the connecting frame blocks the floating impurities on the surface from entering the interior. The floating oil pipe will extract the floating oil on the surface of the machine tool slot from the suction head after negative pressure. During the cutting process, the cutting fluid is separated by the partition plate. Therefore, the liquid will not fall directly to the bottom of the partition, but will flow into the plate cylinder part through the circulation groove after following the guide of the isolation part and the top of the guide part. After entering the plate cylinder part, the cutting fluid will fall into the conical part of the matching plate along the horizontal plane of the matching plate. When the main shaft rotates, it will drive the conical cylinder and the conical spiral blades to rotate along the inner side of the matching plate through the connecting frame. The impurities deposited at the bottom of the matching plate will be pushed by the spiral blades. Due to the low rotation speed, it is not easy to stir the cutting fluid. Impurities such as cutting chips will be pushed to the right side of the structure by the spiral blades and enter the right side of the vertical plate, and move along the slag plate to the slag bucket for direct recovery from the right side later.

A slag plate 6 is fixedly connected to the right side of the vertical plate 5, and a slag bucket 7 is movably connected to the inner side of the slag plate 6.

[0055] By arranging the partition 2 inside the machine tool slot 1 to separate the space inside the machine tool slot 1 and serving as a structural support, the cutting fluid generated during the turning process of the machine tool will directly fall into the inside of the machine tool slot 1. During the cutting process, the cutting fluid will not directly fall to the bottom of the partition 2 due to the separation of the partition 2, but will flow into the plate cylinder 201 through the flow groove 202 along the isolation part 204 and the top of the guide part 203. After entering the plate cylinder 201, the cutting fluid will flow along the matching plate 305. The horizontal plane falls into the conical part of the matching plate 305. When the main shaft 301 rotates, it will drive the conical cylinder 303 and the conical spiral blades 304 to rotate along the inner side of the matching plate 305 through the connecting frame 302.

The inner side of the slag plate 6 is movably connected with a transmission belt 10, and the surface of the transmission belt 10 is fixedly connected with a dial plate 11. By setting the transmission belt 10, the transmission belt 10 is moved on the slag plate 6. When the inside of the plate 6 continues to move, the paddle plate 11 on its surface will move along the moving path of the transmission belt 10, and paddle the solid impurities on the surface of the slag plate 6 from the slag plate 6 to the inside of the slag bucket 7. The front side of the slag plate 6 is fixedly connected to a transmission motor 12, and the inner side of the transmission belt 10 is movably connected to two transmission rollers 13. The output end of the transmission motor 12 is fixedly connected to the front side of the right transmission roller 13. By setting up the transmission motor 12, the transmission roller 13 can be driven to rotate on the outer side of the slag plate 6, and the transmission belt 10 connected thereto can be driven to move through the transmission roller 13, which plays a driving role. The effect of the movement of the dial plate 11 is that the inner side of the left isolation part 204 is fixedly connected with a force frame 18, and the inner side of the force frame 18 is rotatably connected to the main shaft 301. The left side of the inner side of the machine tool slot 1 is fixedly connected with a sealing bracket 19, and the inner side of the sealing bracket 19 is installed with a motor and a reducer 20. The output end of the motor and the reducer 20 is fixedly connected to the main shaft 301. By setting the force frame 18, it is used to support the main shaft 301.

The main pump 21 is arranged in conjunction with the oil pipe 22 to extract and discharge the liquid between the intercepting bucket 307 and the mesh plate 306. Due to the interception of the mesh plate 306, solid impurities will not be extracted, and the blocked solid impurities will be pushed by the rotating spiral blades 304.

[0057] Working principle of this embodiment: When in use, the cutting fluid generated will flow into the plate cylinder 201 through the circulation groove 202 along the isolation part 204 and the top of the guide part 203.

[0060] The cutting fluid generated during the turning process of the machine tool will directly fall into the interior of the machine tool slot 1. After a long period of accumulation, the cutting fluid floating on the top is directly in contact with the external environment, so it contacts impurities and deteriorates to produce floating oil. The floating frame 401 of the floating component 4 floats on the top of the cutting fluid through the floating plate 402, and the blocking frame 404 connected to it through the connecting frame 403 blocks the floating impurities on the surface from entering the interior. The floating oil pipe 406 will extract the floating oil on the surface of the machine tool slot 1 from the suction head 405 after negative pressure.

[0061] The top of the baffle 404 is fixedly connected with a short frame 14, and the top of the short frame 14 is fixedly connected with a shielding piece 15. The short frame 14 is provided to connect the baffle 404 and the shielding piece 15. The shielding piece 15 is located at the top of the baffle 404. When the liquid falls during the top cutting, it can be prevented from falling directly into the inside of the baffle 404 and causing blockage. The top of the guide part 203 is fixedly connected with a limiting rod 16, and the outer side of the connecting frame 403 is fixedly connected with a sliding sleeve 17. The inner side of the sliding sleeve 17 is slidably connected to the limiting rod 16. By providing the limiting rod 16 to cooperate with the sliding sleeve 17, the sliding sleeve 17 is on the outer side of the limiting rod 16. Sliding can facilitate limiting the guide part 203. When the guide part 203 moves along the liquid level surface through the floating plate 402, the sliding sleeve 17 slides on the outside of the limiting rod 16, so that the structure can maintain relative vertical movement and is not prone to horizontal displacement. The left side of the inner side of the machine tool slot 1 is fixedly connected with an auxiliary pump 23, and the input end of the auxiliary pump 23 is fixedly connected with a hose 24.

[0062] Working principle of this embodiment: When in use, the cutting fluid generated during the turning process of the machine tool falls into the interior of the machine tool slot 1. During the falling process, due to the obstruction of the shielding plate 15, the liquid mixed with impurities is not easy to fall into the inner side of the shielding frame 404. After a long period of accumulation, the cutting fluid floating on the top is directly in contact with the external environment, so it contacts impurities and deteriorates to produce floating oil. The floating frame 401 of the floating component 4 floats on the top of the cutting fluid through the floating plate 402, and the shielding frame 404 connected to it through the connecting frame 403 blocks the floating impurities on the surface from entering the interior. At the same time, the auxiliary pump 23 is started, and the floating oil on the surface of the machine tool slot 1 is extracted from the suction head 405 through the hose 24 and the floating oil pipe 406. As the liquid level drops, the floating component 4 will move according to the water level, and the sliding sleeve 17 moves along the limit rod 16 to limit its movement.

10. A method for using a machine tool oil-water separation device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. The cutting fluid generated during the turning process of the machine tool will directly fall into the interior of the machine tool groove (1). Due to the separation of the partition (2), the liquid will not directly fall to the bottom of the partition (2), but will flow into the plate cylinder (201) through the flow groove (202) along the isolation part (204) and the top of the guide part (203). After a long period of accumulation, the cutting fluid floating on the top is directly in contact with the external environment, so it contacts impurities and deteriorates to produce floating oil; S2. The floating frame (401) of the floating assembly (4) floats on the top of the cutting fluid through the floating plate (402), and the blocking frame (404) connected to it through the connecting frame (403) blocks the floating impurities on the surface from entering the interior. At the same time, the auxiliary pump (23) is started to extract the floating oil on the surface of the machine tool tank (1) from the suction head (405) through the hose (24) and the floating oil pipe (406); S3. After entering the plate cylinder (201), the cutting fluid will fall into the conical part of the matching plate (305) along the horizontal surface of the matching plate (305). The main shaft (301) of the separation component (3) is driven by the motor and the reducer (20) to rotate slowly. The conical cylinder (303) and the conical spiral blade (304) connected to it through the connecting frame (302) rotate along the inner side of the matching plate (305). The impurities deposited at the bottom of the matching plate (305) will be pushed by the spiral blade (304). Because the rotation speed is low, it is not easy to stir the cutting fluid. The impurities such as cutting chips will be pushed to the right side of the structure by the spiral blade (304) and enter the right side of the vertical plate (5). The transmission motor (12) drives the transmission belt (10) through the transmission roller (13). The paddle plate (11) connected to it will paddle the impurities at the bottom of the slag plate (6) and move them into the slag bucket (7); S4. The main pump (21) extracts the cutting fluid that has been filtered by the mesh plate (306) and accumulated inside the interception bucket (307) through the oil pipe (22), and discharges it to the outside of the structure for recycling. As the liquid level drops, the cutting fluid gradually fades from the slag plate (6), and the impurities are continuously pushed onto the slag bucket (7) under the movement of the paddle plate (11). After the operation, it is taken out from the right side of the machine tool slot (1) for processing.
