Description

Technical Field

[0001] The invention relates to the technical field of numerical control machining, in particular to a cooling liquid circulation device for a numerical control machining center. Background Art

[0002] CNC machining centers play a vital role in modern manufacturing. A large amount of heat is generated during the machining process. If it is not cooled in time, it will not only affect the machining accuracy, but also may cause problems such as increased tool wear and workpiece deformation. Therefore, coolant circulation equipment has become an indispensable supporting device for CNC machining centers. The coolant circulation equipment is responsible for transporting the coolant to the machining area for cooling, and then recycling, filtering, cooling and reusing it to ensure the stability and efficiency of the machining process.

[0003] There are many shortcomings in the traditional coolant circulation equipment of CNC machining centers. In terms of cooling liquid filtration, traditional equipment usually adopts a simple filter structure with limited filtering effect, and cannot effectively remove tiny impurities and metal debris in the coolant. Over time, these impurities will continue to accumulate in the coolant, affecting the fluidity and heat dissipation performance of the coolant, thereby reducing the cooling effect. In terms of cooling methods, traditional equipment mostly adopts a single air cooling or water cooling method. The air cooling method has low cooling efficiency in high temperature environments, and the water cooling method may cause pipeline corrosion and scaling due to water quality problems, affecting the service life and cooling effect of the equipment. In addition, the traditional equipment is not reasonably designed in terms of coolant storage and buffering, and is prone to problems such as unstable coolant supply and large pressure fluctuations, affecting the processing quality. Moreover, traditional equipment lacks effective means to remove magnetic impurities such as iron filings in the coolant, resulting in iron filings circulating in the system, accelerating equipment wear, and reducing the reliability and stability of the equipment. In response to the above problems, the inventor proposes a coolant circulation equipment for a CNC machining center to solve the above problems. Summary of the invention

[0004] In order to solve the problems of incomplete cooling liquid filtration, single cooling method and difficult iron filings removal in traditional CNC machining centers, the purpose of the present invention is to provide a cooling liquid circulation device for CNC machining centers.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a coolant circulation device for a CNC machining center, including a storage device, a cooling device and a machining center, the storage device is a rectangular hollow structure, and its interior is divided into three layers according to height, the upper part is a main storage bin, a plurality of filter screens are fixedly installed on the lower surface of the main storage bin, and a first temperature sensor is fixedly installed at the center of the upper surface inside the main storage bin, the middle part is a buffer bin, and a plurality of elastic buffer devices corresponding to the number of filter screens are fixedly installed in the buffer bin along the vertical direction, and the lower part is a sedimentation bin, and a funnel is fixedly installed in the middle of the sedimentation bin.

[0006] Preferably, the elastic buffer device includes an elastic bag, the material of the elastic bag is rubber, and an adsorption core is coaxially arranged inside the elastic bag, the adsorption core includes an insulating layer, the material of the insulating layer is polyvinyl chloride, and an iron core is fixedly installed inside the insulating layer, and an electromagnetic coil is surrounded in the gap between the outer cylindrical surface of the iron core and the insulating layer.

[0007] Preferably, a cooling device is provided on the right side of the main storage bin, a first water pump is fixedly installed on the upper surface of the cooling device, a coolant outlet is opened on the right side wall of the main storage bin, the coolant outlet extends outward and is fixedly connected to the first water pump, and the outlet of the first water pump passes through the cooling device and extends to the heat exchange bin inside it.

[0008] Preferably, a heat exchange water pipe is provided in the heat exchange chamber, and the heat exchange water pipe is arranged in a serpentine shape. A second temperature sensor is fixedly installed on one side of the heat exchange chamber, and a water cooling liquid outlet and a water cooling liquid inlet are opened on the side wall of the heat exchange chamber, and the water cooling liquid outlet and the water cooling liquid inlet both penetrate the side wall of the cooling device and extend to the outside.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The present invention is provided with a multi-layer filtering structure. The filter net on the lower surface of the main storage bin can initially intercept larger particle impurities in the coolant. The funnel in the sedimentation bin uses the conical structure and the bottom leakage hole to cause the impurities to settle under the action of gravity and concentrate at the bottom, which is easy to clean. The adsorption core in the elastic buffer device uses the electromagnetic principle to absorb tiny metal debris. In this way, various impurities in the coolant can be removed in all directions, effectively ensuring that the coolant always maintains good fluidity and heat dissipation performance, greatly reducing the possibility of equipment failure due to impurity accumulation, significantly improving production efficiency, and ensuring that the processing process can be carried out continuously and stably;

[0011] 2. The present invention adopts a cooling method in which the heat exchange water pipes are arranged in a serpentine shape in the heat exchange chamber and work in coordination with an external water-cooled liquid circulation system. The serpentine arrangement greatly increases the contact area and time between the coolant and the heat exchange water pipes, and the heat exchange efficiency is significantly improved. At the same time, this method avoids direct contact between the coolant and the external water source, reducing the risk of pipeline corrosion and scaling due to water quality problems. In addition, the first water pump and the second water pump in the equipment can ensure that the coolant flows stably and quickly in the circulation system, further enhancing the cooling effect, enabling the equipment to adapt to different processing environments and processing intensities, and ensuring the stable operation of the machining center;

[0012] 3. The adsorption core in the elastic buffer device of the present invention uses the electromagnetic principle to adsorb iron filings. During the processing, iron filings will inevitably enter the coolant, and the present invention effectively avoids the circulation and accumulation of iron filings in the equipment through the electromagnetic adsorption effect of the adsorption core. This measure reduces the blockage and wear problems caused by iron filings in the equipment, extends the service life of the equipment, and improves the quality of the coolant, thereby ensuring the processing accuracy and stability of the machining center, and providing a strong guarantee for the production of high-quality processed products.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-8 As shown, the present invention provides a coolant circulation device for a CNC machining center, including a storage device 1, a cooling device 2 and a machining center 3. The storage device 1 is a hollow rectangular structure, and its interior is divided into three layers according to height. The upper part is a main storage bin 11, and a plurality of filter screens 112 are fixedly installed on the lower surface of the main storage bin 11, and a first temperature sensor 111 is fixedly installed at the center of the upper surface inside the main storage bin 11; the middle part is a buffer bin 12, and a plurality of elastic buffer devices 121 corresponding to the number of filter screens 112 are fixedly installed in the buffer bin 12 along the vertical direction; the lower part is a sedimentation bin 13, and a funnel 131 is fixedly installed in the middle of the sedimentation bin 13.

[0025] By adopting the above technical solution, the main storage bin 11 is mainly used to store coolant. The filter 112 on its lower surface can perform preliminary filtering on the coolant, intercept larger particles of impurities in the coolant, and prevent these impurities from entering the subsequent circulation system, thereby avoiding the impurities from causing adverse effects such as wear and blockage on the equipment. The first temperature sensor 111 at the center of the upper surface inside the main storage bin 11 can monitor the temperature of the coolant in real time. When the temperature exceeds the set range, a signal can be sent in time so that the operator can take corresponding measures to ensure that the coolant temperature is in a suitable working range and ensure the normal operation of the machining center. On the one hand, the elastic buffer device 121 in the buffer bin 12 can play a buffering role in the coolant circulation process, stabilize the pressure of the coolant, and reduce the impact of pressure fluctuations on the equipment; on the other hand, it can absorb impurities such as tiny metal debris in the coolant, further purify the coolant, and improve the quality of the coolant. The funnel 131 in the middle of the sedimentation bin 13 can make the impurities in the coolant gradually settle to the bottom of the funnel under the action of gravity. By regularly cleaning the funnel, the precipitated impurities in the coolant can be effectively removed, the service life of the coolant can be extended, and the stable operation of the entire coolant circulation system can be ensured.

[0026] The elastic buffer device 121 includes an elastic bag 1211, which is made of rubber, and an adsorption core 1212 is coaxially arranged inside the elastic bag 1211. The adsorption core 1212 includes an insulating layer 12121, which is made of polyvinyl chloride, and an iron core 12123 is fixedly installed inside the insulating layer 12121. An electromagnetic coil 12122 is surrounded in the gap between the outer cylindrical surface of the iron core 12123 and the insulating layer 12121.

[0027] By adopting the above technical solution, the elastic bag 1211 is made of rubber, and its good flexibility and elasticity play a key role in the coolant circulation. When the coolant pressure fluctuates, the elastic bag 1211 effectively buffers the pressure change by its own elastic deformation, prevents excessive pressure from impacting the equipment, and ensures the stable flow of the coolant. The adsorption core 1212 is located coaxially inside the elastic bag 1211, and its insulating layer 12121 is made of polyvinyl chloride. The material has excellent insulation performance. When the electromagnetic coil 12122 is energized, it can reliably prevent current leakage and eliminate electrical problems such as short circuits, ensuring the safe operation of the equipment. The iron core 12123 is fixed in the insulating layer 12121 When the electromagnetic coil 12122 is energized, the iron core 12123 can significantly enhance the magnetic field strength, provide strong magnetic force for adsorbing tiny metal debris and other impurities in the coolant, effectively improve the purity of the coolant, reduce the wear and corrosion of the equipment by impurities, extend the service life of the equipment, and ensure the machining accuracy and stability of the machining center. The electromagnetic coil 12122 is wrapped around the gap between the outer cylindrical surface of the iron core 12123 and the insulating layer 12121. By accurately controlling the on and off of the current, the presence or absence of magnetism of the adsorption core 1212 can be conveniently controlled. When adsorbing impurities, power is turned on to generate a magnetic field, and when cleaning impurities, power is turned off to eliminate the magnetic field. The operation is simple and energy-saving and efficient, which greatly improves the practicability and reliability of the equipment.

[0028] A cooling device 2 is provided on the right side of the main storage bin 11, and a first water pump 23 is fixedly installed on the upper surface of the cooling device 2. A coolant outlet 113 is opened on the right side wall of the main storage bin 11, and the coolant outlet 113 extends outward and is fixedly connected to the first water pump 23. The outlet of the first water pump 23 passes through the cooling device 2 and extends to the heat exchange bin 21 inside it.

[0029] By adopting the above technical scheme, the cooling device 2 arranged on the right side of the main storage bin 11 is used to cool the circulating coolant to ensure that the coolant can effectively take away the heat generated by the machining center. The first water pump 23 on the upper surface of the cooling device 2 is one of the power sources for the coolant circulation. It is fixedly connected to the coolant outlet 113 opened on the right side wall of the main storage bin 11, and can extract the coolant in the main storage bin 11. The position and connection method of the coolant outlet 113 ensure that the coolant can smoothly flow from the main storage bin 11 to the first water pump 23. The outlet of the first water pump 23 passes through the cooling device 2 and extends to the heat exchange bin 21 inside it, so that the extracted coolant can accurately enter the heat exchange bin 21 for heat exchange cooling. This layout and connection method realizes the orderly flow of coolant from storage to cooling, ensures the normal operation of the entire coolant circulation system, helps to maintain the machining center working at an appropriate temperature, and improves machining accuracy and equipment service life.

[0030] A heat exchange water pipe 211 is arranged in a serpentine shape in the heat exchange chamber 21. A second temperature sensor 212 is fixedly installed on one side of the heat exchange chamber 21. A water-cooling liquid outlet 213 and a water-cooling liquid inlet 214 are provided on the side wall of the heat exchange chamber 21. The water-cooling liquid outlet 213 and the water-cooling liquid inlet 214 both penetrate the side wall of the cooling device 2 and extend to the outside.

[0031] By adopting the above technical solution, the heat exchange water pipe 211 is arranged in a serpentine shape in the heat exchange chamber 21. This design cleverly increases the flow and residence time of the coolant in the heat exchange chamber 21, thereby greatly improving the heat exchange efficiency between the coolant and the heat exchange water pipe 211. The coolant is transported from the storage device to the heat exchange water pipe 211 through the pipeline. During the flow in the heat exchange water pipe 211, the heat is effectively dissipated. The water-cooling liquid inlet 214 and the water-cooling liquid outlet 213 on the side wall of the heat exchange chamber 21 are respectively connected to the external water-cooling liquid circulation system. The external water-cooling liquid flows in from the water-cooling liquid inlet 214 and surrounds the outside of the heat exchange water pipe 211. Since the temperature of the coolant in the heat exchange water pipe 211 is relatively high, the heat will be transferred to the external water-cooling liquid. After the water-cooling liquid absorbs the heat, the temperature rises, and then flows out from the water-cooling liquid outlet 213 , thereby realizing the function of cooling the coolant in the heat exchange water pipe 211 through external water-cooling liquid circulation. The second temperature sensor 212 installed on one side of the heat exchange chamber 21 monitors the coolant temperature in real time. The operator can judge whether the coolant temperature is appropriate based on the temperature data, so as to adjust the equipment operation status in time, ensure that the coolant temperature always meets the heat dissipation requirements of the machining center, and ensure that the machining process is stable and efficient. At the same time, the coolant may be added with components for flushing the machine tool to clean the surface of the machine tool, but these components will not be mixed with the external water-cooling liquid. The two are completely separated by the wall of the heat exchange water pipe 211, and circulate independently without interfering with each other. This not only ensures the cleaning and heat dissipation function of the coolant on the machine tool, but also ensures that the simple cooling effect of the water-cooling liquid can be effectively exerted, maintaining the normal operation of the entire coolant circulation system and the machining center.

[0032] A coolant inlet 132 is provided at the bottom of the left side wall of the sedimentation bin 13 . The coolant inlet 132 is connected to the coolant pool 31 of the machining center 3 through a coolant delivery pipe 311 . A ball check valve 3111 is fixedly installed on the coolant delivery pipe 311 .

[0033] By adopting the above technical scheme, the coolant inlet 132 opened at the bottom of the left side wall of the sedimentation bin 13 provides an entrance for the coolant in the coolant pool 31 of the machining center 3 to flow back to the sedimentation bin 13. When the coolant used in the machining process of the machining center 3 needs to be circulated back to the equipment for treatment, the coolant is connected to the sedimentation bin 13 through the coolant delivery pipe 311. The ball check valve 3111 fixedly installed on the coolant delivery pipe 311 plays a key unidirectional conduction role, ensuring that the coolant can only flow from the coolant pool 31 of the machining center 3 to the sedimentation bin 13 without backflow. This feature effectively prevents the coolant that has been preliminarily filtered or treated in the sedimentation bin 13 from flowing back to the machining center 3 during the operation of the equipment, avoiding pollution to the machining center 3 or affecting its normal operation. At the same time, it also ensures the stability of the flow direction of the entire coolant circulation system, so that the coolant can be precipitated, filtered, cooled and other processing processes in sequence according to the predetermined path, thereby improving the efficiency of coolant recycling, helping to maintain the stable operation of the coolant circulation system of the entire CNC machining center, and ensuring the machining quality and the normal service life of the equipment.

[0034] A closed door 133 is provided at the bottom of the rear side wall of the sedimentation bin 13 . The closed door 133 is connected to the side wall of the sedimentation bin 13 via a hinge, and a sealing gasket is provided at the edge of the closed door 133 .

[0035] By adopting the above technical solution, the closed door 133 at the bottom of the rear side wall of the sedimentation bin 13 provides a convenient channel for cleaning the impurities accumulated in the sedimentation bin 13. The closed door 133 is connected to the side wall of the sedimentation bin 13 by a hinge. This connection method allows the closed door 133 to be flexibly opened and closed. When the sedimentation bin 13 needs to be cleaned, the operator can easily open the closed door 133 to conveniently remove the impurities deposited at the bottom of the sedimentation bin 13. When the equipment is operating normally, the closed door 133 is closed, and the sealing gasket set at its edge plays an important role. The sealing gasket can effectively fill the gap between the closed door 133 and the sedimentation bin. The gap between the side walls of 13 prevents the coolant from leaking from the sedimentation bin 13, which not only ensures the sealing of the sedimentation bin 13, ensures that the coolant can normally precipitate impurities in the sedimentation bin 13 and maintains the stability of the sedimentation process, but also avoids the coolant leakage from polluting the surrounding environment of the equipment or affecting other components of the normal operation of the equipment. At the same time, good sealing performance also helps to maintain the pressure stability of the entire coolant circulation system, so that the coolant can circulate smoothly according to the predetermined process, improves the reliability and stability of the equipment, extends the service life of the equipment, and ensures the continuous and efficient operation of the CNC machining center.

[0036] The storage device 1 also includes a battery compartment 14 and a control panel 15. The battery compartment 14 is located on the right side of the buffer compartment 12. A battery assembly 141 is installed inside the battery compartment 14. An induction transmission line 1411 is connected to the battery assembly 141. The induction transmission line 1411 passes through the side wall of the buffer compartment 12 and is connected to the electromagnetic coil 12122 in the elastic buffer device 121.

[0037] By adopting the above technical solution, the battery compartment 14 and the battery assembly 141 inside it provide an independent power source for the electromagnetic coil 12122 in the elastic buffer device 121. The layout design of the battery compartment 14 on the right side of the buffer compartment 12 is reasonable, which does not affect the functions of other parts of the storage device 1, and can be conveniently electrically connected to the elastic buffer device 121. The battery assembly 141 is connected to the electromagnetic coil 12122 through the induction transmission line 1411. The design of the induction transmission line 1411 passing through the side wall of the buffer compartment 12 ensures that the electric energy can be stably transmitted to the electromagnetic coil 12122. During the operation of the equipment, when it is necessary to start the electromagnetic suction When the electromagnetic adsorption function is used to remove impurities such as metal debris in the coolant, the battery assembly 141 supplies power to the electromagnetic coil 12122 to generate a magnetic field, so that the adsorption core 1212 can play an adsorption role. This independent power supply method makes the electromagnetic adsorption function not affected by external power fluctuations, thereby ensuring the stability and reliability of the adsorption effect. At the same time, the operator can monitor and adjust the power supply status of the battery assembly 141 and the operating parameters of the entire equipment through the control panel 15, thereby realizing intelligent control of the equipment, improving the convenience and flexibility of equipment operation, and helping to improve the overall performance and work efficiency of the coolant circulation equipment of the CNC machining center.

[0038] The cooling device 2 also includes a water pump compartment 22, which is located at the lower side of the cooling device 2. A second water pump 221 is installed in the water pump compartment 22. A circulating water pipe 2211 is connected to the second water pump 221. One end of the circulating water pipe 2211 is connected to the second water pump 221, and the other end is fixedly installed at the water inlet end of the machining center 3.

[0039] By adopting the above technical solution, the water pump compartment 22 in the cooling device 2 provides a stable installation position for the second water pump 221. The layout located on the lower side of the cooling device 2 helps to optimize the overall structure of the equipment, making the center of gravity of the equipment more stable, and is convenient for connection and maintenance with other components. The second water pump 221 in the water pump compartment 22 is one of the key power components for the circulation of the coolant. It is connected to the water inlet end of the machining center 3 through the circulating water pipe 2211. When the second water pump 221 is started, it can extract the coolant cooled by the heat exchange compartment 21 from the cooling device 2 and stably transport it to the machining center 3 through the circulating water pipe 2211. The water inlet end of the machining center 3 ensures that the machining center 3 always has an adequate supply of coolant during the machining process, realizing efficient recycling of the coolant. One end of the circulating water pipe 2211 is connected to the second water pump 221, ensuring that the coolant can smoothly enter the circulating water pipe from the water pump. The other end is fixedly installed on the water inlet end of the machining center 3. This design makes the circulation path of the coolant in the equipment clear and orderly, ensuring the stable operation of the entire coolant circulation system, helping to improve the machining accuracy of the machining center 3 and the service life of the equipment, while improving the utilization efficiency of the coolant, reducing the waste of coolant, and reducing production costs.

[0040] The bottom of the funnel 131 is conical, and a leakage hole 1311 is opened at the tip of the cone. The diameter of the leakage hole 1311 is smaller than the diameter of the top opening of the funnel 131 .

[0041] By adopting the above technical solution, the conical design at the bottom of the funnel 131 utilizes the principle of gravity, so that when the coolant falls naturally in the sedimentation bin 13, the impurities carried therein are more likely to gather at the tip of the cone under the action of gravity. This shape can effectively guide the sedimentation direction of the impurities and improve the sedimentation efficiency. The diameter of the leak hole 1311 opened at the tip of the cone is smaller than the diameter of the top opening. On the one hand, the discharge speed of the impurities can be controlled to prevent the impurities from being discharged too quickly without being fully precipitated, thereby ensuring the sedimentation effect; on the other hand, the smaller diameter of the leak hole 1311 can reduce the possibility of the coolant flowing out with the impurities, further ensuring the coolant The purity of the coolant. During the operation of the equipment, the coolant flows in from the upper part of the sedimentation bin 13, and the impurities gradually settle to the cone tip in the funnel 131. When the impurities need to be cleaned, the closed door 133 at the bottom of the sedimentation bin 13 can be opened to discharge the impurities gathered near the leak hole 1311 at the cone tip. The operation is convenient and efficient. This design helps to extend the service life of the coolant and reduce the damage of impurities to subsequent equipment components (such as the heat exchange water pipe 211 and water pump in the cooling device 2), thereby ensuring the stable operation of the entire coolant circulation equipment and improving the processing quality of the CNC machining center and the overall reliability of the equipment.

[0042] A control panel 15 is disposed on the front side of the storage device 1 , and the control panel 15 is electrically connected to each electronic component.

[0043] By adopting the above technical solution, the control panel 15 on the front side of the storage device 1 provides a convenient operation interface for the operator. Since it is electrically connected to each electronic component, the operator can centrally monitor and manage the operation status of the entire coolant circulation device through the control panel 15. For example, the operator can view the coolant temperature data monitored by the first temperature sensor 111 in the main storage bin 11 on the control panel 15, and adjust the operation parameters of the cooling device 2 in time according to the temperature conditions to ensure that the coolant temperature is appropriate. The coolant temperature in the heat exchange bin 21 fed back by the second temperature sensor 212 in the cooling device 2 can also be intuitively displayed on the control panel 15. , so that the operator can judge whether the heat exchange effect is normal. At the same time, the control panel 15 can also control the battery assembly 141 in the battery compartment 14 to power the electromagnetic coil 12122 of the elastic buffer device 121, realize the opening and closing of the electromagnetic adsorption function, and flexibly control the adsorption core 1212 to adsorb impurities such as metal debris in the coolant. In addition, through the control panel 15, the operator can easily obtain the working information of various parts of the equipment, such as the operating status of the water pump, the opening and closing status of each valve, etc. When the equipment is abnormal, the control panel 15 may display corresponding fault alarm information to help the operator quickly locate the problem and take effective solutions.

[0044] Working principle: When the present invention is used, the coolant used in the machining process of the machining center 3 first flows back to the sedimentation bin 13 through the coolant pool 31 and the coolant delivery pipe 311. The ball check valve 3111 on the coolant delivery pipe 311 ensures that the coolant can only flow into the sedimentation bin 13 in one direction. The coolant impurities flowing into the sedimentation bin 13 are precipitated to the bottom of the funnel 131 under the action of gravity. The conical design of the funnel 131 and the leakage hole 1311 at the cone tip are conducive to the accumulation and controlled discharge of impurities. Then, the coolant in the sedimentation bin 13 is initially precipitated and then pumped from the sedimentation bin 13 to the main storage bin 11 through the coolant outlet 113 by the first water pump 23. The main storage The filter screen 112 on the lower surface of the main storage bin 11 performs preliminary filtering on the coolant to intercept larger particles of impurities. At this time, the first temperature sensor 111 at the center of the upper surface of the main storage bin 11 monitors the coolant temperature in real time. Then, the coolant that has undergone preliminary filtration flows out from the coolant outlet 113 of the main storage bin 11 under the action of the first water pump 23, and is transported to the heat exchange bin 21 inside the cooling device 2 through the outlet of the first water pump 23 on the upper surface of the cooling device 2. The coolant in the heat exchange water pipe 211 in the heat exchange bin 21 performs heat exchange with the external water cooling liquid circulation system. The external water cooling liquid flows into the surrounding heat exchange water pipe 211 from the water cooling liquid inlet 214 and then flows out from the water cooling liquid outlet 214. The cooling liquid flows out of the water outlet 213 and takes away the heat of the cooling liquid. The second temperature sensor 212 on one side of the heat exchange chamber 21 monitors the cooling liquid temperature in real time. The staff can judge the cooling effect according to the temperature data and adjust the parameters such as the water cooling liquid flow rate when necessary. After that, the cooled cooling liquid is transported back to the water inlet end of the machining center 3 through the circulating water pipe 2211 under the action of the second water pump 221 to continue to participate in the cooling cycle of the machining center 3. During the whole process, the elastic buffer device 121 in the buffer chamber 12 plays a role in buffering the pressure fluctuation of the cooling liquid and absorbing impurities such as tiny metal debris. The elastic bag 1211 uses rubber material to elastically buffer the pressure, and the electromagnetic coil 121 When power is turned on, the iron core 12123 enhances the magnetic field so that the adsorption core 1212 adsorbs impurities. The battery assembly 141 in the battery compartment 14 supplies power to the electromagnetic coil 12122 through the induction transmission line 1411. The staff can control the power supply of the battery assembly 141 through the control panel 15 to turn the electromagnetic adsorption function on and off. At the same time, the operating status of each electronic component of the equipment, such as the temperature sensor data and the operating status of the water pump, is monitored on the control panel 15.
