[0046] It is worth noting that the vortex separator 101 is a technical means well known to technical personnel in this field, which includes a cone body and a liquid inlet, a liquid outlet, a slag outlet, etc. The liquid containing particulate impurities is injected into the cone body of the separator from the liquid inlet at a high speed along the tangential direction under a certain pressure, and makes a spiral motion from top to bottom, thereby generating an external vortex in the cone body. In this process, the solid particles in the liquid are thrown to the inner wall of the cone body under the action of centrifugal force due to their large density, and then move to the bottom along the inner wall under the drive of gravity and liquid, and finally discharged from the slag outlet at the bottom. After the separation, the clean liquid will rise in a spiral along the axis of the cone body after reaching the bottom of the cone body, forming an internal vortex, and finally discharged from the liquid outlet of the vortex separator, thereby achieving the purpose of separating dirty liquid from clean liquid. The rest will not be elaborated.

The inclined plate 804 guides the water flow distribution, promotes the precipitation of impurities and prevents the loss of sediment. The combination of the two can significantly improve the impurity removal ability of the sedimentation box 800 and further purify the cooling water.

[0051] The connecting component includes an L-shaped tube 502 connected to the bottom right side of the magnetic separation box 500.

[0063] It is worth noting that the clamping parts include clamping strips 806 fixedly connected to both ends of the magnetic plate 802, and clamping grooves 805 corresponding to the clamping strips 806 on the inner walls of both sides of the sedimentation box 800. The two groups of clamping strips 806 are respectively clamped in the corresponding side clamping grooves 805. Through the setting of the clamping parts, when the magnetic plate 802 needs to be installed, it is only necessary to clamp the clamping strips 806 on both sides of the magnetic plate 802 in the inner cavity of the corresponding side clamping grooves 805 to complete the installation of the magnetic plate 802, thereby facilitating the installation of the magnetic plate 802 and the disassembly of the magnetic plate 802, thereby cleaning the sediment in the sedimentation box 800.

[0064] Preferably, one end of the magnetic plate 802 that meanders upward is fixedly connected to a strip filter plate 801, and the length of the strip filter plate 801 is set corresponding to the internal width of the sedimentation box 800. Through the setting of the strip filter plate 801, fine impurities in the cooling water flowing into the strip filter plate 801 are filtered to prevent them from flowing into the next step, thereby further improving the sedimentation effect of the sedimentation box 800.

[0065] Working principle:

[0066] First, after the device is started, the first delivery pump 106 located at the top right side of the bottom plate 100 starts to work, and its input end draws unpurified cooling water from the outside, and then, through the water inlet pipe 105 connected to its output end, the cooling water is delivered to the liquid inlet end of the vortex separator 101 along an upward winding path;

[0067] The cooling water entering the vortex separator 101 forms a high-speed rotating vortex flow inside the vortex separator 101. According to the principle of centrifugal force, impurities with higher density are thrown toward the wall of the device, and move toward the bottom under the action of gravity, and are finally discharged through the guide pipe 107 connected to the slag discharge end. One end of the guide pipe 107 is inclined to the left and is aligned with the opening of the holding box 504 above the magnetic separation box 500, so that the impurities can smoothly fall into the holding box 504, and the relatively clean water after preliminary separation flows out from the liquid outlet end of the vortex separator 101 and is sent to the magnetic separation box 500 through the delivery pipe 104;

[0068] When the water containing the residual metal debris flows into the magnetic separation box 500, the motor 507 on the fixed plate 508 on one side of the magnetic separation box 500 drives the magnetic separation roller 501 to start rotating. Since the magnetic separation roller 501 is magnetic, it will adsorb the metal debris in the cooling water, so that the metal debris adheres to the surface of the magnetic separation roller 501. As the magnetic separation roller 501 continues to rotate, the adsorbed metal debris is brought to the guide groove 503 above the magnetic separation box 500 and located on the left side of the magnetic separation roller 501. The bottom of the inlet end of the guide groove 503 is arranged in an arc shape corresponding to the surface of the magnetic separation roller 501, which can well receive the metal debris coming from the magnetic separation roller 501, and then the debris falls into the guide groove 503 along the downward tilt direction of the outlet end of the guide groove 503. In the holding box 504 embedded on the left side of the magnetic separation box 500, several groups of first filter plates 510 embedded at the bottom of the holding box 504 can further filter and separate the cooling water that may be accompanied, and the pull rod 701 on one side of the scraper 700 slidably connected to the inner cavity of the holding box 504 can be pulled to regularly clean the collected metal debris, so that it is discharged from the holding box 504 and falls into the collection box 601 below that is clamped on the surface of the support column 108 through the clamping ring 600. At the same time, the flow limiting plate 509 fixedly connected to the inner wall on the upper right side of the magnetic separation box 500 has one end on the left side extending downward to the position below the mouth of the conveying pipe 104, thereby avoiding the direct impact of the water flow on the magnetic separation roller 501 and ensuring the stability and order of the magnetic separation process;

[0069] The water treated by the magnetic separation box 500 flows into the sedimentation box 800 through the L-shaped tube 502 connected to the bottom of the right side thereof. At the same time, the water flow entering the sedimentation box 800 impacts the surface of the magnetic plate 802. The magnetic plate 802 plays a role in absorbing the residual metal debris in the coolant. One end of the bottom of the magnetic plate is arranged in a J-shape to the upper right, which increases the contact area with the water flow and better captures the metal debris that may remain in the water. The two sides of the magnetic plate are fixed in the corresponding clamping grooves 805 on the inner walls of the two sides of the sedimentation box 800 through the clamping strips 806 to ensure stable placement. The strip filter plate 801 is fixedly connected to the end of the magnetic plate 802 that is bent upward, and its length is the same as that of the sedimentation box 800. 0 is set correspondingly to the internal width, which can further filter the water flow, intercept some fine impurities, and improve the overall purification effect of the sedimentation box 800, so that the water flows into the interior of the sedimentation box 800. At the same time, the baffle plate 803 at the center first hinders the water flow, slowing down the water flow speed. After the water flow hits the baffle plate 803, the kinetic energy is partially converted into potential energy, the flow rate is reduced, and some fine particles of impurities suspended in the water have more time to settle to the bottom of the box under the action of gravity. The inner wall of the bottom of the sedimentation box 800 is located on the right side of the baffle plate 803. The upper end of the inclined plate 804 extends to one side to a position higher than the baffle plate 803, guiding the water flow to be reasonably distributed and further promoting the precipitation of impurities.

[0070] The cooling water after precipitation and impurities adsorption in the precipitation tank 800 is pumped by the second delivery pump 200 installed on the upper left side of the bottom plate 100. The input end of the second delivery pump 200 is connected to the inside of the precipitation tank 800 through the connecting pipe 201. After the water is pumped out, it is finally transported back to the inner cavity of the water tank 300 through the connecting pipe 202 connected to the output end and the solenoid valve 402 connected to the other end of the connecting pipe 202, so as to realize the recycling of cooling water.

[0071] In the whole process, the liquid level control component plays an important role at all times. The controller 401 fixedly installed at the bottom of the magnetic separation box 500 is the core control component. The electromagnetic float valve 400 fixedly installed in the inner cavity of the water tank 300 monitors the water level in the water tank 300 in real time and transmits the water level signal to the controller 401 through a wire. The electromagnetic valve 402 is electrically connected to the signal output end of the controller 401. The controller 401 controls the opening and closing of the electromagnetic valve 402 according to the water level information to adjust the amount of reflux water entering the water tank 300. At the same time, the first delivery pump 106 and the second delivery pump The signal input end of 200 is also electrically connected to the signal output end of the controller 401 through a wire. The controller 401 will control the start and stop of the two delivery pumps in a timely manner according to the water level of the water tank 300 and the operating logic of the entire system. For example, when the water level of the water tank 300 reaches the set upper limit, the controller 401 controls the first delivery pump 106 to stop pumping water to prevent the water tank 300 from overflowing; and when the water level is lower than a certain value, the second delivery pump 200 is controlled to start supplying water to the water tank 300, ensuring that the entire device can stably and continuously purify and recycle the cooling water.
