Description

Technical Field

[0001] The utility model relates to the technical field of coolant recovery and filtration, and more specifically to a coolant recovery and filtration device for a numerically controlled lathe. Background Art

[0002] During the operation of the CNC lathe, the spindle box needs to rotate at a high speed, so that the workpiece can be turned quickly when the turning tool contacts the workpiece surface. However, a large amount of heat will be generated during the contact between the turning tool and the workpiece, causing the friction surface to heat up, and the temperature of the workpiece surface and the turning tool surface to rise to a very high level. Therefore, it is often necessary to spray coolant to achieve the cooling effect and avoid high-temperature deformation of the cutting edge and the component surface. After the coolant is used up, in order to reduce the cost of coolant use, the coolant is often recovered and filtered to remove impurities for recycling.

[0003] At present, in the process of coolant recovery and treatment, the iron filings and engine oil in the coolant are mostly treated by filtering and adsorption. However, in the filtering process, the iron filings on the filter are easy to accumulate together, causing the mesh of the filter to be blocked, affecting the filtering and circulation effect of the coolant. At the same time, the oil stains are easily adsorbed by adsorption materials alone, which is easy to remain and is not sufficient and comprehensive, resulting in insufficient and incomplete coolant recovery and filtration treatment, and poor filtration effect. Therefore, there is an urgent need to improve the technology of coolant recovery and filtration structure to improve this equipment.

[0004] Therefore, the utility model provides a cooling liquid recovery and filtering device for a numerically controlled lathe. Utility Model Content

[0027] During use of the present solution, after the used coolant is introduced into the interior of the receiving tube 1, the iron filings therein are filtered out through the filter screen 7. At the same time, the dual-axis motor 901 in the suction cleaning mechanism 9 is started to drive the short round-headed protruding rod 902 to rotate, prompting the short round-headed protruding rod 902 to drive multiple magnet long blocks 903 and the cleaning brush body 904 to rotate along the surface of the filter screen 7. In the process of rotation, the iron filings are cleaned and adsorbed, driving the iron filings to be attracted and attached to the magnet long block 903, reducing the aggregation on the filter screen 7, avoiding multiple blockages in the mesh of the filter screen 7, and ensuring its filtering smoothness. When the dual-axis motor 901 is working, the long round-headed protruding rod 1001 below is also driven by it to rotate, and drives a pair of extruding round rods 10 02 is rotated, so that a pair of extruded round rods 1002 intermittently contact with the control switch 1003 during the rotation process, and press it, so that the pair of control switches 1003 respectively drive the two pairs of electric one-way valves 1006 to open, causing the coagulant 1005 to fall into the coolant, and then dispersed to various places inside the coolant under the stirring of the two pairs of stirring rods 1007, driving the residual engine oil in the coolant to gather together, so that it can be fully and thoroughly filtered during the subsequent filtration by the adsorption filter plate 1008, reducing the residual engine oil pollution and enhancing the recovery and filtration effect of the coolant. The coolant after the recovery and filtration treatment is discharged and collected outward along the drain pipe 5 when the conduction control valve 6 is turned on, which is convenient for the staff to drive the coolant for recycling.

[0028] See also Figure 1-2 The suction and cleaning mechanism 9 includes a dual-axis motor 901 installed inside the built-in cylinder 8, a short round-headed protruding rod 902 is rotatably connected between the built-in cylinder 8 and the filter screen 7, and the upper end of the dual-axis motor 901 is fixedly connected to the lower end of the short round-headed protruding rod 902, and the outer end of the short round-headed protruding rod 902 is fixedly connected to a plurality of evenly distributed long magnet blocks 903, and the lower ends of the plurality of long magnet blocks 903 are fixedly connected to a cleaning brush body 904, and the lower end of the cleaning brush body 904 is in contact with the upper end of the filter screen 7, and an aggregation and adsorption mechanism 10 is installed between the dual-axis motor 901 and the mounting plate 2 and the drain pipe 5.

[0029] During use of this solution, the dual-axis motor 901 is started to drive the short round-headed protruding rod 902 to rotate, prompting the short round-headed protruding rod 902 to drive multiple long magnet blocks 903 and the cleaning brush body 904 to rotate along the surface of the filter screen 7, so that the cleaning brush body 904 cleans the iron filings on the surface of the filter screen 7 during the rotation process. At the same time, the long magnet block 903 uses magnetic attraction to attract and collect the iron filings during the cleaning process, so that they are concentrated near the long magnet block 903, avoiding multiple blockages in the mesh of the filter screen 7, thereby ensuring the filtering smoothness of the filter screen 7.

[0030] See also Figure 1-2 The surfaces of the filter screen 7 and the magnet long block 903 are both provided with an anti-rust coating.

[0031] During use of the present invention, the anti-rust coating is provided, so that the surfaces of the filter screen 7 and the long magnet block 903 are not easily corroded during long-term use, thereby extending their service life.

[0032] See also Figure 1-4 The aggregation adsorption mechanism 10 includes a long round head convex rod 1001 rotatably connected to the built-in cylinder 8, the upper end of the long round head convex rod 1001 is fixedly connected to the lower end of the dual-axis motor 901, and the outer end of the long round head convex rod 1001 is fixedly connected to a pair of extrusion rods 1002, and the inner wall of the built-in cylinder 8 is installed with a pair of left-right symmetrical control switches 1003, and the extrusion rods 1002 are in contact with the control switches 1003, and the mounting plate 2 is embedded with two pairs of left-right symmetrical control switches 1003.

[0033] During the use of this solution, when the dual-axis motor 901 is working, it also drives the long round head protruding rod 1001 below to rotate, so that it drives a pair of extruding round rods 1002 and two pairs of stirring rods 1007 to rotate. When the pair of extruding round rods 1002 rotate to correspond to a pair of control switches 1003, they contact and press them to drive the two pairs of electric one-way valves 1006 to open, so that the coagulant 1005 inside the adding cylinder 1004 falls under the action of gravity and enters the coolant until the pair of extruding round rods 1002 are separated from the pair of control switches 1003, and the two pairs of electric one-way valves 1006 are opened. 006 is closed, and the addition of the coagulant 1005 stops. When the pair of extrusion rods 1002 and the pair of control switches 1003 are rotated and pressed next time, the electric one-way valve 1006 is driven to open again, prompting the coagulant 1005 to continue to fall and add. The coagulant 1005 that falls into the coolant is dispersed to various places inside the coolant under the stirring of the two pairs of stirring rods 1007, driving the residual engine oil in the coolant to gather together, reducing the residual engine oil in the coolant, so that the adsorption filter plate 1008 can fully and comprehensively adsorb and filter it, thereby enhancing the recovery and filtration treatment effect of the coolant.

When the coagulant aid 1005 inside the adding cylinder 1004 is insufficient, the sealing cover 11 is removed to open the upper end of the adding cylinder 1004, so that the staff can add the coagulant aid 1005 therein conveniently.
