This process can reduce the waste chips carried during the circulation of the coolant, which is beneficial to improving the cleanliness of the coolant, reducing the wear on the equipment, and at the same time beneficial to improving the machining quality.

[0022] A coolant circulation filtration system described in the present invention is used in conjunction with a motor, a connecting shaft, a mesh plate, and a first filter chamber. When the motor works, its output end will drive the connecting shaft to rotate, and the connecting shaft will synchronously drive the outer mesh plate to rotate. Impurities in the coolant in the first filter chamber can be scooped up by the rotation of the mesh plate, making it convenient for workers to handle the scooped foreign matter.

[0023] The coolant circulation filtration system described in the present invention cooperates with a transmission gear disc one, a transmission gear disc two, a transmission belt one, a transmission rod and a scraper.

[0024] The coolant circulation filtration system described in the present invention is used in combination with a transmission shaft, a stirring rod, a transmission gear plate three and a transmission belt two. When the motor is working and drives the transmission gear plate one to rotate, the transmission gear plate one drives a group of transmission gear plates two to rotate through the transmission belt one, and the other group of transmission gear plates two will rotate synchronously and drive the transmission shaft to rotate through the transmission belt two. When the transmission shaft rotates, it will drive the outer stirring rod to rotate. The rotation of the stirring rod can accelerate the cooling process of the coolant, thereby increasing the cooling speed of the coolant by the device.

[0025] The coolant circulation and filtration system described in the present invention is used in conjunction with a cam, a crank, a sleeve, a piston plate, a one-way valve 1, a one-way valve 2 and an aeration pipe. When the transmission shaft rotates, the cam is driven to rotate, and then the cam drives the crank to move left and right.

At this time, the air inside the sleeve can be transported to the inside of the aeration pipe through the one-way valve 2, and then the gas can be filled into the inside of the secondary filtering device through the aeration pipe to aerate the coolant. During the aeration process, air enters the coolant and generates a large number of bubbles. The stirring effect of these bubbles can promote the exchange of substances in the coolant, and help to release impurities, heat, etc. in the coolant into the environment faster, thereby improving the circulation efficiency and heat dissipation effect of the coolant.

The primary filtering device 201 is installed at the bottom of the machining center 1 near the coolant outlet 101.

The filter screen is located at the drainage position of the secondary filtering device 202. The internal through-hole diameter of the filter screen is smaller than the internal through-hole diameter of the filter screen 203. The secondary filtering device 202 can filter smaller waste chips. A filter screen 203 is provided between the primary filtering device 201 and the secondary filtering device 202.

[0030] Specifically, the coolant sprayed during the machining process in the machining center 1 passes through the machining part, cools the machining part, and then flows out of the machining center 1 through the coolant outlet 101, and then passes through the primary filter device 201. The filter net 203 between the primary filter device 201 and the secondary filter device 202 can filter the milling waste chips carried in the coolant, and then enters the secondary filter device 202. The secondary filter device 202 can further filter the waste chips with a smaller volume to obtain a relatively pure coolant. Under the action of the circulation device 4, the purified and filtered coolant can be drained into the interior of the machining center 1, and circulated again to participate in the cooling of the machining parts inside the machining center 1. This process can reduce the waste chips carried during the circulation of the coolant, which is beneficial to improving the cleanliness of the coolant, reducing the wear on the equipment, and at the same time beneficial to improving the machining quality.

[0031] Please refer to Figure 2 The circulation device 4 includes a water pump 401 and a return pipe 402. The water pump 401 is installed on the side of the filtering mechanism 2.

The end of the return pipe 402 away from the water pump 401 is connected to the machining center 1.

[0032] Specifically, in order to realize the circulation of the coolant filtered by the filter mechanism 2 to the interior of the machining center 1 for further use, after the filter mechanism 2 filters the coolant discharged from the machining center 1 after use, the water pump 401 works, and the water pump 401 transports the coolant filtered by the filter mechanism 2 to the interior of the return pipe 402, and then transports the filtered coolant to the interior of the machining center 1 through the return pipe 402 for further use.

[0033] Please refer to Figure 3 The primary filtering device 201 includes a motor 2011, a connecting shaft 2012, a mesh plate 2013 and a first filter chamber 2014. The first filter chamber 2014 is arranged at the bottom of the machining center 1 near the coolant outlet 101. The connecting shaft 2012 is rotatably installed inside the first filter chamber 2014. The mesh plate 2013 is installed on the outer surface of the connecting shaft 2012. The motor 2011 is installed on the side of the filtering mechanism 2, and the output end of the motor 2011 is connected to the connecting shaft 2012.

[0034] Please refer to Figure 3 The mesh plates 2013 are equidistantly distributed on the outer surface of the connecting shaft 2012.

[0035] Specifically, in order to achieve preliminary cooling treatment of the used coolant, the used coolant in the machining center 1 will be transported to the inside of the first filter chamber 2014, and then work through the motor 2011. The output end of the motor 2011 will drive the connecting shaft 2012 to rotate, and the connecting shaft 2012 will synchronously drive the outer mesh plate 2013 to rotate. The impurities in the coolant can be scooped up by the rotation of the mesh plate 2013, which is convenient for workers to handle the scooped foreign matter. At the same time, the rotation of the mesh plate 2013 can accelerate the cooling of the coolant, thereby facilitating the later use of the coolant.

[0036] Please refer to Figure 4 A transmission rod 303 is rotatably installed inside the first filter chamber 2014 near one end of the filter screen 203 , and a scraper 304 is rotatably installed on the outer side of the transmission rod 303 , and the side surface of the scraper 304 is in contact with the filter screen 203 .

[0037] Please refer to Figure 3 and Figure 4 A transmission gear disc 1 3 is installed on the outer side of the output end of the motor 2011, and a transmission rod 303 passes through the outer side of the first filter chamber 2014 and is installed with two sets of transmission gear discs 2 301. A transmission belt 1 302 is installed on the outer side of the transmission gear disc 1 3 and a set of transmission gear discs 2 301.

[0038] Specifically, in order to achieve the processing of the filter 203 and prevent larger impurities from clogging the inside of the filter 203 and affecting the transportation and filtration of the coolant, when the motor 2011 is working, its output end will synchronously drive the transmission gear disc 1 3 to rotate, and the transmission gear disc 1 3 will drive a group of transmission gear discs 2 301 to rotate through the transmission belt 1 302. When a group of transmission gear discs 2 301 rotates, it can drive the transmission rod 303 to rotate. Through the rotation of the transmission rod 303, the transmission rod 303 will drive the scraper 304 to move under the action of the threaded transmission. When the scraper 304 moves under the action of the rotation of the transmission rod 303, the scraper 304 can scrape away the impurities adhered to the surface of the filter 203 to prevent the impurities from gradually accumulating and clogging the inside of the filter 203 and affecting the transportation and filtration of the coolant.

[0039] Please refer to Figure 3 A transmission shaft 5 is rotatably installed inside the secondary filtering device 202 , and a stirring rod 501 is installed on the outer surface of the transmission shaft 5 .

[0040] Please refer to Figure 3 A transmission gear disc 3 502 is installed on the outer side of the transmission shaft 5 passing through one end of the filter mechanism 2, and a transmission belt 2 503 is installed on the outer side of the transmission gear disc 3 502 and another set of transmission gear disc 2 301.

[0041] Specifically, in order to accelerate the cooling process of the coolant, when the motor 2011 works to drive the transmission gear disc 1 3 to rotate, the transmission gear disc 1 3 drives a group of transmission gear discs 2 301 to rotate through the transmission belt 1 302, and the other group of transmission gear discs 2 301 will rotate synchronously and drive the transmission shaft 5 to rotate through the transmission belt 2 503. When the transmission shaft 5 rotates, it will drive the outer stirring rod 501 to rotate. The rotation of the stirring rod 501 can accelerate the cooling process of the coolant.

[0042] Please refer to Figure 3 and Figure 6 A cam 6 is installed at one end of the transmission shaft 5 passing through the filtering mechanism 2, and a crank 601 is rotatably installed on the side of the cam 6. A sleeve 603 is installed on the outer side of the filtering mechanism 2 near the crank 601, and a piston plate 604 is installed at the bottom end of the crank 601 located inside the sleeve 603. The piston plate 604 is movable and located inside the sleeve 603. An aeration pipe 602 is installed inside the secondary filtering device 202, and one end of the aeration pipe 602 is connected to the sleeve 603, one end of the crank 601 is rotatably connected to the cam 6, and the other end of the crank 601 is rotatably connected to the piston plate 604.

[0043] Please refer to Figure 6 A one-way valve 605 is installed on the top of the sleeve 603, and a one-way valve 606 is installed between the sleeve 603 and the aeration pipe 602.

[0044] Specifically, in order to improve the treatment effect of the device on the coolant, when the transmission shaft 5 rotates, it will drive the cam 6 to rotate, and then the cam 6 will drive the crank 601 to move left and right. When the connection between the crank 601 and the cam 6 is close to one end of the sleeve 603, the crank 601 can be driven to move toward the inside of the sleeve 603. At this time, the air inside the sleeve 603 can be transported to the inside of the aeration pipe 602 through the one-way valve 2 606, and then the gas can be filled into the inside of the secondary filter device 202 through the aeration pipe 602 to aerate the coolant. During the aeration process, air enters the coolant and generates a large number of bubbles. The stirring effect of these bubbles can promote the exchange of substances in the coolant, and help the impurities and heat in the coolant to be released into the environment faster, thereby improving the circulation of the coolant. Efficiency and heat dissipation effect, at the same time, some harmful gases and odors in the coolant can be removed, its quality can be improved, the generation of harmful substances can be reduced, the stability and durability of the coolant can be improved, and aeration can enhance the fluidity and mixing uniformity of the coolant, improve the heat dissipation performance of the system, and can also improve the quality of the coolant and enhance the filtering effect, so the blockage and replacement frequency of the filtering structure can be reduced, and the maintenance cost can be reduced. When the crank 601 moves under the action of the rotation of the cam 6 and drives the piston plate 604 to move toward the end away from the sleeve 603, the external gas is transported to the interior of the sleeve 603 through the one-way valve 605, so that it is convenient for the crank 601 to drive the piston plate 604 to move in the later stage, and the gas is transported to the interior of the aeration pipe 602 again, so as to aerate the coolant inside the filter mechanism 2.

[0045] Working principle: during the machining process in the machining center 1, the coolant sprayed passes through the machining part and cools the machining part, then flows out of the machining center 1 through the coolant outlet 101, and then flows into the first filter chamber 2014, and then works through the motor 2011. The output end of the motor 2011 will drive the connecting shaft 2012 to rotate, and the connecting shaft 2012 will synchronously drive the outer mesh plate 2013 to rotate. The impurities in the coolant can be picked up by the rotation of the mesh plate 2013, which is convenient for the worker to deal with the picked up foreign matter later. At the same time, the rotation of the mesh plate 2013 can accelerate the cooling of the coolant, and then the coolant can pass through the filter screen 203 between the primary filter device 201 and the secondary filter device 202. The milling waste chips carried in the coolant are filtered and then enter the secondary filtering device 202. The secondary filtering device 202 can further filter the waste chips with smaller volume to obtain relatively pure coolant. When the motor 2011 is working, its output end will synchronously drive the transmission gear disc 1 3 to rotate. The transmission gear disc 1 3 will drive a group of transmission gear discs 2 301 to rotate through the transmission belt 1 302. When a group of transmission gear discs 2 301 rotates, it can drive the transmission rod 303 to rotate. Through the rotation of the transmission rod 303, the transmission rod 303 will drive the scraper 304 to move under the action of the threaded transmission. When the scraper 304 moves under the action of the rotation of the transmission rod 303, the impurities adhering to the surface of the filter 203 can be removed through the scraper 304. The scraping treatment is carried out, and at the same time, when the transmission toothed disc 1 3 drives a group of transmission toothed discs 2 301 to rotate through the transmission belt 1 302, the other group of transmission toothed discs 2 301 will rotate synchronously and drive the transmission shaft 5 to rotate through the transmission belt 2 503. When the transmission shaft 5 rotates, the stirring rod 501 on the outside will be driven to rotate. The rotation of the stirring rod 501 can accelerate the cooling treatment of the cooling liquid. At the same time, the transmission shaft 5 will also drive the cam 6 to rotate, and the cam 6 will drive the crank 601 to move left and right. When the connection between the crank 601 and the cam 6 is close to one end of the sleeve 603, the crank 601 can be driven to move toward the inside of the sleeve 603. At this time, the air inside the sleeve 603 can be transported to the inside of the aeration pipe 602 through the one-way valve 2 606, and then the The gas is filled into the interior of the secondary filter device 202 through the aeration pipe 602 to aerate the coolant. When the crank 601 moves under the action of the rotation of the cam 6 and drives the piston plate 604 to move toward the end away from the sleeve 603, the external gas is transported to the interior of the sleeve 603 through the one-way valve 605, which is convenient for the crank 601 to drive the piston plate 604 to move in the later stage, and the gas is transported to the interior of the aeration pipe 602 again to aerate the coolant inside the filter mechanism 2. Finally, the water pump 401 works to transport the coolant filtered by the filter mechanism 2 to the interior of the return pipe 402, and then transports the filtered coolant to the interior of the machining center 1 through the return pipe 402 for use.

[0046] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
