Description

Technical Field

[0001] This invention relates to the field of cutting fluid cleaning technology, specifically to a cutting fluid cleaning system and method for metal machining centers. Background Technology

[0002] With the rapid development of modern manufacturing, the metal processing industry occupies a pivotal position in industrial production. Cutting fluid, as an important auxiliary material in metal processing, has multiple functions such as cooling, lubrication, cleaning, and rust prevention, playing a crucial role in improving processing efficiency and ensuring processing quality. However, during use, cutting fluids are contaminated by metal particles, chips, microorganisms, and other pollutants, leading to a gradual decline in their performance and even affecting the stability of the processing and product quality. Traditional cutting fluid cleaning methods mainly rely on simple physical filtration and fluid replacement. While this approach can extend the service life of cutting fluid to some extent, it suffers from limited filtration effectiveness, resource waste, and environmental pollution.

[0003] For example, patent application CN107552228B discloses a metal cutting fluid cleaning device, including a frame with a rotating frame, a transmission mechanism, a drive motor, and a chip removal plate. The rotating frame is connected to the drive motor via the transmission mechanism. At least two magnetic rings are arranged around the rotating frame. The chip removal plate slides on the frame and has a chip removal groove at its lower part. The magnetic rings consist of six magnetic iron rods of the same length, with adjacent magnetic iron rods hinged to each other, and at least two magnetic iron rods are magnetically attracted to the rotating frame. The chip removal plate has through holes, and the magnetic iron rods are inserted into the through holes. The rotating frame drives the magnetic iron rods attracted to the rotating frame to rotate. When the magnetic iron rods pass through the container holding the cutting fluid, they absorb metal impurities such as iron filings due to magnetic attraction, and then are discharged through the through holes, achieving the separation of cutting fluid and iron filings, keeping the cutting fluid clean, and reducing environmental pollution.

[0004] The aforementioned prior art uses magnetic attraction to filter iron filings from the cutting fluid, maintaining the purity of the cutting machine. However, in actual use, the performance of the cutting fluid will significantly decline after long-term use. The aforementioned prior art can only remove impurities in the cutting fluid, but cannot replenish the key components lost in the cutting fluid, so the cutting fluid cannot restore its original performance, thus affecting the effectiveness of subsequent use. Therefore, this application proposes a cutting fluid cleaning system and method for metal processing centers. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting fluid cleaning system and method for metal processing centers to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cutting fluid cleaning system for a metal processing center, comprising a cleaning tank with a built-in cavity, an outer shell fixedly connected to one side of the cleaning tank, a drive motor fixedly connected to the top of the cleaning tank, the output end of the drive motor extending into the cavity of the cleaning tank and fixedly connected to a rotating drum, a plurality of stirring blades uniformly fixedly connected to the outer surface of the rotating drum, an additive storage chamber for storing additives being opened inside the rotating drum, a plurality of gravity chute troughs uniformly opened inside the plurality of stirring blades, a plurality of discharge holes penetrating the stirring blades being uniformly opened on one side of the plurality of gravity chute troughs, the ends of the plurality of gravity chute troughs that are close to each other communicating with the additive storage chamber, and a discharge assembly cooperating with the drive motor being uniformly arranged inside the plurality of gravity chute troughs.

[0007] Preferably, the dispensing assembly includes counterweight beads that are rolled inside a plurality of gravity chute spools, all of which are constructed to be inclined.

[0008] Preferably, each of the plurality of gravity troughs is fixedly connected to a one-way valve near one end of the storage chamber, and the one-way valve is used to guide the additive in the storage chamber into the gravity trough in one direction. The inside of the rotating drum is fixedly connected to an inlet for conveying the additive into the storage chamber.

[0009] Preferably, the cleaning box has a liquid outlet pipe connected to its cavity on the side away from the outer shell, a door is hinged to one end of the cleaning box, and a mounting base for fixing it is fixedly connected to the top of the cleaning box.

[0010] Preferably, an inner feed tube communicating with the cleaning chamber is fixedly connected inside the outer shell, and a debris chamber is constructed between the inside of the outer shell and the outer surface of the inner feed tube. A filter plate is rotatably connected to the top of the inner feed tube, and the filter plate has multiple filter holes uniformly opened inside the top of the inner feed tube for cutting fluid to pass through. The outer surface of the filter plate is placed on the top surface of the debris chamber.

[0011] Preferably, a fixing ring is fixedly connected inside the debris cavity and below the filter plate. The fixing ring has a plurality of first drop grooves evenly distributed inside. The filter plate has a plurality of second drop grooves that are adapted to the first drop grooves evenly distributed on its outer surface. In the initial state, the plurality of second drop grooves are respectively misaligned with the plurality of first drop grooves.

[0012] Preferably, the outer surface of the filter plate is fixedly connected to a turntable that is rotatably connected to the outer surface of the outer tube shell, and the outer surface of the turntable is uniformly fixedly connected with a plurality of rubber protrusions.

[0013] Preferably, a fixing frame is fixedly connected inside the outer shell and above the inner inlet pipe, a sweeping plate that contacts the top surface of the filter plate is fixedly connected to the bottom of the fixing frame, and a hinged door is hinged to the bottom of the outer shell.

[0014] A method for cleaning cutting fluid in metalworking centers, including the following steps:

[0015] S1. By connecting the outer shell to the cutting fluid pipeline, the cutting fluid is introduced into the cleaning tank, where the outer shell can filter impurities in the cutting fluid.

[0016] S2. When all the cutting fluid enters the cleaning tank, the drive motor is then turned on to drive its output end to rotate, thereby driving the drum to rotate. At this time, under the action of centrifugal force, it works with the discharging component to transport the additive in the storage chamber to the cleaning tank and mix with the cutting machine. Under the stirring of the stirring blades, it will be further mixed.

[0017] S3. Then, allow the cutting fluid to settle. When needed, connect the cutting fluid line to the cleaning tank to extract the treated cutting fluid from the cleaning tank.

[0018] Preferably, in step S1, the speed of the drive motor is controllable.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. Inside the cleaning tank, the drive motor rotates the drum, and the stirring blades stir the cutting fluid. At the same time, centrifugal force causes the counterweight beads to roll in the gravity chute, thereby pushing the additive through the one-way valve into the gravity chute and finally releasing it into the cleaning tank. This method achieves automatic and uniform mixing of the additive and improves the performance recovery effect of the cutting fluid.

[0021] 2. By setting up a filter plate, impurities in the cutting fluid can be filtered out. The cooperation between the first drop groove and the fixed ring in the filter plate can facilitate the collection of debris that is blocked. The sweeping plate reduces the amount of debris adhering to the filter plate, improves its filtration efficiency, and reduces clogging. Attached Figure Description

Detailed Implementation

[0033] 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.

[0034] Example 1: Please refer to Figure 1 , Figure 2 and Figure 6This invention provides a technical solution: a cutting fluid cleaning system for a metal processing center, including a cleaning tank 100 with a built-in cavity. A drive motor 202 is fixedly connected to the top of the cleaning tank 100. The output end of the drive motor 202 extends into the cavity of the cleaning tank 100 and is fixedly connected to a rotating drum 200. Multiple stirring blades 201 are uniformly fixedly connected to the outer surface of the rotating drum 200. An additive storage chamber 203 for storing additives is opened inside the rotating drum 200. Multiple gravity troughs 204 are uniformly opened inside the multiple stirring blades 201. Multiple discharge holes 205 penetrating the stirring blades 201 are uniformly opened on one side of the multiple gravity troughs 204. The ends of the multiple gravity troughs 204 that are close to each other are connected to the additive storage chamber 203. Discharge components cooperating with the drive motor 202 are uniformly arranged inside the multiple gravity troughs 204. The additive storage chamber 203 is used to store additives. The additives can be automatically discharged into the cavity of the cleaning tank 100, so that the cutting fluid and the additives are mixed to obtain an initial cleaning effect.

[0035] This additive can be an oil-based agent, which allows cutting oil to quickly penetrate into the cutting zone and form a physical adsorption film, reducing friction between chips, tools, and workpieces.

[0036] It can also be used as an extreme pressure additive: it usually contains organic compounds such as sulfur, phosphorus, and chlorine. These compounds can react chemically with the metal surface at high temperatures to generate chemical adsorption films such as iron sulfide, iron chloride, and iron phosphide. These films are more resistant to high temperature and high pressure than physical adsorption films, and help prevent the metal interface from being in complete direct contact under boundary lubrication conditions, thereby maintaining lubrication and reducing friction.

[0037] Or emulsifier: a surfactant that enables mineral oil to emulsify with water to form a stable emulsion.

[0038] Or antibacterial agents: Their main function is to kill bacteria in the cutting fluid and inhibit their growth and reproduction, thereby preventing the cutting fluid from becoming contaminated and spoiled.

[0039] Or antioxidants: used to prevent polyols, acids and fatty acids in cutting fluid from being oxidized and causing odor, thereby effectively extending the service life of the cutting fluid.

[0040] Or preservatives: can extend the service life of cutting fluid, prevent cutting fluid from deteriorating due to contamination, and also play an antibacterial role.

[0041] Or lubricant: can reduce the friction between the cutting fluid and the metal workpiece, thereby effectively protecting the machine parts and extending the service life of the machine.

[0042] Please refer to Figures 5 to 7To achieve mutual cooperation with the stirring blade 201 and improve the mixing efficiency of the additive and cutting fluid, a discharge assembly is provided, including counterweight beads 206 that are rolled inside multiple gravity chute 204s. The multiple gravity chute 204s are all constructed to be inclined. One-way valves 208 are fixedly connected to one end of each gravity chute 204 near the storage chamber 203. The one-way valves 208 are used to guide the additive in the storage chamber 203 to the gravity chute 204 in one direction. An inlet 207 for conveying the additive to the storage chamber 203 is fixedly connected inside the rotating drum 200. The gravity chute 204s are constructed to be inclined, so that when the stirring blade 201 is stationary, its counterweight beads 206 will be placed near the end of the storage chamber 203 due to gravity. At this time, the channel of the gravity chute 204 will be blocked, so that the additive in the storage chamber 203 cannot enter the gravity chute 204 through the counterweight beads 206.

[0043] Specifically, the drive motor 202 is started to rotate its output end. At this time, the output end of the drive motor 202 drives the rotating drum 200 to rotate, causing the stirring blades 201 on its outer surface to stir the cutting fluid. At the same time, when the rotating drum 200 rotates, it will generate a certain centrifugal force. This centrifugal force will cause multiple counterweight beads 206 in the stirring blades 201 to roll in the gravity chute 204, causing the multiple counterweight beads 206 to move away from the rotating drum 200. At this time, the additive in the storage chamber 203 will adhere to the inside of the storage chamber 203 under the action of centrifugal force and finally be transported to the inside of the gravity chute 204 through multiple one-way valves 208. At this time, because the counterweight beads 206 are in a position away from the one-way valves 208 under the action of centrifugal force, the additive transported to the gravity chute 204 will be transported to the inside of the cleaning tank 100 through multiple outlet holes 205 to mix with the cutting fluid. Under the action of the stirring blades 201, it will be further mixed.

[0044] In summary, within the cleaning tank 100, the drive motor 202 drives the rotating drum 200 to rotate, and the stirring blades 201 stir the cutting fluid. At the same time, centrifugal force causes the counterweight beads 206 to roll in the gravity chute 204, thereby pushing the additive through the one-way valve 208 into the gravity chute 204 and finally releasing it into the cleaning tank 100. This method achieves automatic and uniform mixing of the additive, improving the performance recovery effect of the cutting fluid.

[0045] Example 2: Please refer to Figure 1-8The present invention also provides a technical solution: a cutting fluid cleaning system for a metal processing center, wherein an outer shell 300 is fixedly connected to one side of a cleaning tank 100, and an inner inlet pipe 302 communicating with the cavity of the cleaning tank 100 is fixedly connected inside the outer shell 300. A debris cavity is constructed between the inside of the outer shell 300 and the outer surface of the inner inlet pipe 302. A filter plate 304 is rotatably connected to the top of the inner inlet pipe 302, and the filter plate 304 has a plurality of filter holes uniformly opened inside the top of the inner inlet pipe 302 for cutting fluid to pass through. The outer surface of the filter plate 304 is placed on the top surface of the debris cavity. A fixing ring 305 is fixedly connected inside the debris cavity and below the filter plate 304. A plurality of first drop grooves 306 are uniformly opened inside the fixing ring 305, and a plurality of second drop grooves 307 adapted to the first drop grooves 306 are uniformly opened on the outer surface of the filter plate 304. In the initial state, the plurality of second drop grooves 307 are respectively misaligned with the plurality of first drop grooves 306.

[0046] For further user assistance, please refer to [link / reference]. Figures 8 to 10 The outer surface of the filter plate 304 is fixedly connected to a turntable 303 that is rotatably connected to the outer surface of the outer tube shell 300. The outer surface of the turntable 303 is uniformly fixedly connected with multiple rubber protrusions. The turntable 303 extends to the outer surface of the outer tube shell 300, which makes it convenient for the user to operate the filter plate 304 to rotate from the outside. At the same time, its protrusions can increase the friction. Further, indicators can be constructed on the outer surface of the turntable 303. These indicators can be used to determine the specific position of the inner second drop groove 307 of the turntable 303, ensuring that it is staggered with the first drop groove 306 during subsequent use.

[0047] Furthermore, to facilitate cleaning of the filter plate 304 and maintain its high filtration efficiency, a fixing frame 308 is fixedly connected inside the outer shell 300 and above the inner inlet pipe 302. A sweeping plate 309 that contacts the top surface of the filter plate 304 is fixedly connected to the bottom of the fixing frame 308. A hinged door 310 is hinged to the bottom of the outer shell 300. The fixing frame 308 is placed on the top surface of the filter plate 304. When the filter plate 304 rotates, it will come into contact with the sweeping plate 309. At this time, the sweeping plate 309 will move in a circular motion on the top surface of the filter plate 304, thereby cleaning it.

[0048] Specifically, the filter holes in the filter plate 304 can block impurities in the used cutting fluid, thereby obtaining impurity-free cutting fluid. By rotating the turntable 303, the filter plate 304 is driven to rotate. At this time, the filter plate 304 rotates and comes into contact with the fixed sweeping plate 309 above. As the filter plate 304 continues to rotate, the surface impurities scraped off by the sweeping plate 309 are sent into the interior of multiple second drop troughs 307. At this time, under the continuous rotation of the turntable 303, the multiple second drop troughs 307 will gradually overlap with the multiple first drop troughs 306. When they overlap, the impurities will pass through the second drop troughs 307 and the first drop troughs 306 into the cavity between the inner surface of the outer shell 300 and the outer surface of the inner inlet tube 302. This cavity is used to store impurities. Afterwards, the cavity between the inner surface of the outer shell 300 and the outer surface of the inner inlet tube 302 can be cleaned by pulling the hinged door 310.

[0049] To facilitate the fixing of the cleaning box 100 and adapt it to different usage environments, the top of the cleaning box 100 is fixedly connected to a mounting base 102 for fixing it, which also facilitates opening the cleaning box 100 to deliver new additives into the storage chamber 203. One end of the cleaning box 100 is hinged to a box door 101 for easy use of the cutting fluid treated therein. The side of the cleaning box 100 away from the outer shell 300 is fixedly connected to an outlet pipe 103 that communicates with its chamber.

[0050] In summary, by setting up the filter plate 304, impurities in the cutting fluid can be filtered out. The cooperation between the first drop groove 306 and the fixing ring 305 in the filter plate 304 can facilitate the collection of debris blocked by the filter. The sweeping plate 309 reduces the amount of debris adhering to the filter plate 304, improves its filtration efficiency, and reduces clogging.

[0051] Example 3: Please refer to Figures 1 to 10 The present invention also provides a technical solution: a method for cleaning cutting fluid in a metal machining center, comprising the following steps:

[0052] S1. By connecting the connector 301 to the cutting fluid pipeline, the cutting fluid is introduced into the cleaning tank 100. When the cutting fluid passes through the outer shell 300, the impurities carried inside it will be blocked by the filter plate 304.

[0053] S2. When all the cutting fluid enters the cleaning tank 100, the drive motor 202 is turned on to drive its output end to rotate, thereby driving the drum 200 to rotate. At this time, under the action of centrifugal force, multiple counterweight beads 206 in the stirring blade 201 roll in its gravity chute 204, so that the storage chamber 203 is connected to the inner cavity of the cleaning tank 100 through the gravity chute 204 and multiple outlet holes 205. At this time, the additive in the storage chamber 203 will adhere to the inside of the storage chamber 203 under the action of centrifugal force and finally be transported to the inside of the gravity chute 204 through multiple one-way valves 208. The additive transported to the gravity chute 204 will be transported to the inside of the cleaning tank 100 through multiple outlet holes 205 and mixed with the cutting fluid. Under the stirring of the stirring blade 201, it will be further mixed.

[0054] S3. Then the cutting fluid is allowed to settle. When needed, the cutting fluid pipeline is connected to the outlet pipe 103 through a flange to extract the treated cutting fluid from the cleaning tank 100.

[0055] S4. When it is necessary to clean the debris attached to the surface of the filter plate 304, the filter plate 304 can be rotated by rotating the turntable 303. At this time, the filter plate 304 will rotate and come into contact with the sweeping plate 309 fixed above. The filter plate 304 will continue to rotate and the debris on the surface that is removed by the sweeping plate 309 will be sent into the interior of multiple second drop troughs 307. At this time, under the continuous rotation of the turntable 303, the multiple second drop troughs 307 will gradually overlap with the multiple first drop troughs 306. When they overlap, the debris will pass through the second drop troughs 307 and the first drop troughs 306 and enter the cavity between the inner surface of the outer shell 300 and the outer surface of the inner feed pipe 302. After that, the collected debris can be processed by pulling the hinged door 310.

[0056] In step S1, the rotation speed of the drive motor 202 is controllable because it is constructed with multiple dispensing holes 205. This allows the height of the counterweight bead 206 to be limited when the drive motor rotates quickly or slowly, thereby limiting the number of dispensing holes 205 that can be opened and ensuring the amount of additive released. When the amount of additive delivered reaches a certain level, the drum 200 can be rotated slowly to allow the counterweight bead 206 to block the gravity chute 204 and stop the delivery of the additive liquid.

[0057] Working principle: In use, the connection port 301 is first connected to the cutting fluid pipeline, allowing the used cutting fluid to be easily introduced into the cleaning tank 100 for cleaning. When the cutting fluid enters the outer casing 300 through the connection port 301, it is first filtered by the filter plate 304 and then enters the inner inlet pipe 302. Finally, it is transported to the cleaning tank 100 by gravity. Impurities in the cutting fluid are blocked by the filter plate 304 and pushed to the top surface of the turntable 303. When cleaning the filter plate 304 is required, the turntable 303 is rotated, which in turn rotates the filter plate 304. 04 The rotation will bring the filter plate 304 into contact with the fixed sweeping plate 309 above. At this time, the filter plate 304 will continue to rotate and scrape the surface debris removed by the sweeping plate 309 into the interior of multiple second drop troughs 307. At this time, under the continuous rotation of the turntable 303, the multiple second drop troughs 307 will gradually overlap with the multiple first drop troughs 306. When they overlap, the debris will pass through the second drop troughs 307 and the first drop troughs 306 into the cavity between the inner surface of the outer shell 300 and the outer surface of the inner inlet pipe 302. This cavity is used to store debris. Afterwards, the cavity between the inner surface of the outer shell 300 and the outer surface of the inner inlet pipe 302 can be cleaned by pulling the hinged door 310.

[0058] After the used cutting fluid enters the cleaning tank 100, the drive motor 202 can be turned on to rotate its output end. At this time, the output end of the drive motor 202 drives the rotating drum 200 to rotate, causing the stirring blades 201 on its outer surface to stir the cutting fluid. At the same time, when the rotating drum 200 rotates, it will generate a certain centrifugal force. This centrifugal force will cause multiple counterweight beads 206 in the stirring blades 201 to roll in the gravity chute 204, causing the multiple counterweight beads 206 to move away from the rotating drum 200. At this time, the additive in the storage chamber 203 will adhere to the inside of the storage chamber 203 under the action of centrifugal force and finally be transported to the inside of the gravity chute 204 through multiple one-way valves 208. At this time, because the counterweight beads 206 are in a position away from the one-way valves 208 under the action of centrifugal force, the additive transported to the gravity chute 204 will be transported to the inside of the cleaning tank 100 through multiple outlet holes 205 to mix with the cutting fluid. Under the action of the stirring blades 201, it will be further mixed.
