Description

Technical Field

[0001] This utility model relates to the field of cutting fluid treatment technology, specifically to a machine tool cutting fluid filtration, purification and circulation device. Background Technology

[0002] Cutting fluids used in lathes are suitable for various machining scenarios. In turning, drilling, and tapping, they can be used to machine various metal materials such as steel, iron, copper, and aluminum. They function to cool the tool and workpiece, reduce friction, lower cutting forces, improve surface finish, and extend tool life. They are also suitable for different types of lathes, including automatic lathes and CNC lathes. To improve the utilization rate of cutting fluid and reduce production costs, specialized cutting fluid purification devices are usually required to treat the cutting fluid.

[0003] As disclosed in CN208696984U, a cutting fluid purification and circulation system for machine tools belongs to the field of cutting fluid purification technology. It includes a cutting fluid purifier filter tank, a diaphragm pump, a liquid turbulence-laminar flow conversion device, a cutting fluid-waste oil separation tank, a cutting fluid waste oil removal device, and an ozone generator, all connected sequentially by process circulation pipelines. The cutting fluid purifier filter tank includes a tank body and a sealing connection device; the inlet of the diaphragm pump is connected to the outlet of the filter tank. The liquid turbulence-laminar flow conversion device is an energy dissipation, damping, and forced flow guiding channel. The cutting fluid waste oil removal device includes a vertical guide support for a waste oil collector and a waste oil collector. The outlet of the cutting fluid-waste oil separation tank is connected to the ozone generator outlet via a second tee connector. This system can simultaneously and effectively purify and sterilize the cutting fluid from numerous machine tools used in an enterprise, extending the service life of the cutting fluid and reducing waste.

[0004] Although the above-mentioned solution can simultaneously purify and sterilize the cutting fluid to extend its service life and reduce waste, the device has a relatively complex structure, occupies a large area, and its subsequent maintenance and cleaning are inconvenient. Therefore, we propose a machine tool cutting fluid filtration, purification and circulation device, which solves the problem of inconvenient subsequent maintenance and cleaning and improves the ease of use of the device. Utility Model Content

[0005] The purpose of this invention is to provide a machine tool cutting fluid filtration, purification, and circulation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A machine tool cutting fluid filtration, purification, and circulation device includes a filter cylinder. An inlet is located at the top of the filter cylinder, and a first filter screen is fitted inside the inlet. A conical sedimentation zone is located at the bottom of the filter cylinder, and a first drain outlet is fixedly located at the bottom of the conical sedimentation zone. An outlet pipe is fixedly located on one side of the filter cylinder, and one end of the outlet pipe is connected to a T-type filter. One end of the T-type filter is connected to a magnetic adsorption mechanism, and one end of the magnetic adsorption mechanism is fixedly connected to a pump.

[0008] Furthermore, the magnetic adsorption mechanism includes an adsorption cylinder with six through holes and one mounting hole at its top. The mounting hole is located at the center of the top surface of the adsorption cylinder. The six through holes are arrayed around the center of the top surface of the adsorption cylinder. A cylinder cover is threaded to the mounting hole. Six magnetic rods corresponding to the through holes are fixedly installed on the bottom surface of the cylinder cover. A leak-proof pad is fixedly installed between the cylinder cover and the adsorption cylinder. The bottom end of each magnetic rod can be inserted into the through hole and extends into the adsorption cylinder. The magnetic rod and the through hole are in clearance fit. A second drain outlet is provided at the bottom of the adsorption cylinder. A valve is installed on the outside of the second drain outlet. A handle is fixedly welded to the top surface of the cylinder cover.

[0009] Furthermore, a second filter screen is fixedly installed inside the T-type filter, and valves are installed on the outside of the first drain outlet and the liquid outlet pipe. The mesh size of the second filter screen is smaller than that of the first filter screen.

[0010] Furthermore, the upper end of the liquid inlet has a funnel-shaped structure, and the lower end has a cylindrical structure. A groove is fixedly provided on the inner wall of the upper end of the liquid inlet. The top of the first filter screen is fixedly provided with an edge that can engage with the groove. A lifting ring is fixedly provided on the top surface of the edge.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This machine tool cutting fluid filtration and purification circulation device achieves preliminary filtration of the cutting fluid before it enters the filter cylinder by means of a first filter screen installed inside the inlet. The installation method of the first filter screen also facilitates the installation, removal and cleaning of the first filter screen by the operator, thereby improving work efficiency. A secondary filtration effect of the cutting fluid is achieved by a T-type filter set at one end of the outlet. The T-type filter has a fixed inclined filter screen inside, and the operator can periodically clean the impurities of the T-type filter by opening the drain port at the bottom of the T-type filter. The operation is simple and convenient.

[0013] This machine tool cutting fluid filtration and purification circulation device uses a magnetic adsorption mechanism connected to one end of a T-type filter. When the secondary filtered cutting fluid enters the adsorption cylinder, it can adsorb iron filings or iron powder inside the cutting fluid, improving the cleanliness of the cutting fluid. Operators can periodically remove the fixing bolts on the cylinder cover, then hold the handle and lift the magnetic suction rod upwards to scrape off the impurities adsorbed on the magnetic suction rod and let them fall to the bottom of the adsorption cylinder. By opening the valve on the outside of the second drain port, the waste liquid can be discharged, achieving a rapid cleaning effect for the magnetic suction rod. It is very convenient to use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example: A machine tool cutting fluid filtration, purification, and circulation device, such as... Figures 1-4 As shown, the system includes a filter cylinder 1, with an inlet 2 at the top and a first filter screen 3 inside the inlet 2. A conical sedimentation zone 11 is located at the bottom of the filter cylinder 1, and a first drain outlet 12 is fixedly located at the bottom of the conical sedimentation zone 11. An outlet pipe 4 is fixedly located on one side of the filter cylinder 1, with one end of the outlet pipe 4 connected to a T-type filter 5. A magnetic adsorption mechanism 6 is connected to one end of the T-type filter 5, and a pump 7 is fixedly connected to one end of the magnetic adsorption mechanism 6. A second filter screen 51 is fixedly located inside the T-type filter 5. Valves are installed on the outside of both the first drain outlet 12 and the outlet pipe 4. The mesh size of the second filter screen 51 is smaller than that of the first filter screen 3. The upper end of the inlet 2 has a funnel-shaped structure, and its lower end has a cylindrical structure. A groove 21 is fixedly located on the inner wall of the upper end of the inlet 2. The top of the first filter screen 3 has an edge 31 that can engage with the groove 21, and a lifting ring 32 is fixedly located on the top surface of the edge 31.

[0022] In this embodiment, machine tool cutting fluid is injected into the filter cylinder 1 through the inlet 2 at the top of the filter cylinder 1. The first filter screen 3 inside the inlet 2 performs preliminary filtration of the cutting fluid, removing large particles of impurities. The pre-filtered cutting fluid then enters the filter cylinder 1. Smaller impurities, such as sand, settle in the conical sedimentation zone 11 at the bottom of the filter cylinder 1. Operators can periodically drain the waste liquid from the conical sedimentation zone 11 by opening the valve of the first drain port 12. The pump 7 is activated to pump the liquid from the conical sedimentation zone 11 inside the filter cylinder 1. The cutting fluid is pumped into the outlet pipe 4 and undergoes secondary filtration through the second filter screen 51 inside the T-type filter 5. This filters out fine impurities inside the cutting fluid, achieving a two-stage filtration effect. The first filter screen 3 can be quickly removed by pulling up the lifting ring 32 during cleaning. When cleaning the T-type filter 5, simply remove the mounting bolts of the second filter screen 51 to open the drain port at the bottom of the T-type filter 5 for cleaning. This filtration structure is simple and convenient to operate, greatly reducing the burden of subsequent cleaning or maintenance work for the staff.

[0023] like Figures 1-3As shown, the magnetic adsorption mechanism 6 includes an adsorption cylinder 61. The top of the adsorption cylinder 61 has six through holes 62 and one mounting hole 63. The mounting hole 63 is located at the center of the top surface of the adsorption cylinder 61. The six through holes 62 are arrayed around the center of the top surface of the adsorption cylinder 61 outside the mounting hole 63. The mounting hole 63 is threaded to a cylinder cover 64. Six magnetic suction rods 65, corresponding one-to-one with the through holes 62, are fixedly installed on the bottom surface of the cylinder cover 64. A seepage-proof pad is fixedly installed between the cylinder cover 64 and the adsorption cylinder 61. The bottom end of the magnetic suction rods 65 can be inserted into the through holes 62 and extend into the adsorption cylinder 61. The magnetic suction rods 65 and the through holes 62 are in clearance fit. A second drain port 66 is provided at the bottom of the adsorption cylinder 61. A valve is installed on the outside of the second drain port 66. A handle 67 is fixedly welded to the top surface of the cylinder cover 64.

[0024] In this embodiment, six magnetic suction rods 65 are installed inside the adsorption cylinder 61, which adsorb ferromagnetic impurities such as suspended iron filings and iron powder in the cutting fluid onto the surface of the magnetic suction rods 65, achieving a three-stage filtration effect for the cutting fluid. After the magnetic adsorption mechanism 6 has been used for a period of time, the pump 7 and the valve of the outlet are closed. By removing the fixing bolts on the cylinder cover 64, the operator holds the handle 67 and lifts the magnetic suction rods 65 upwards, so that the impurities adsorbed on the magnetic suction rods 65 are scraped off and fall to the bottom of the adsorption cylinder 61. By opening the valve on the outside of the second drain port 66, the waste liquid can be discharged, achieving a rapid cleaning effect for the magnetic suction rods 65, which is very convenient to use.

[0025] In this embodiment, a machine tool cutting fluid filtration and purification circulation device is used. First, the machine tool cutting fluid is injected into the filter cylinder 1 through the inlet 2 at the top of the filter cylinder 1. The first filter screen 3 inside the inlet 2 achieves preliminary filtration of the cutting fluid, removing large particulate impurities. The pre-filtered cutting fluid enters the filter cylinder 1, where smaller impurities such as sand settle into the conical sedimentation zone 11 at the bottom of the filter cylinder 1. The operator can periodically discharge the waste liquid in the conical sedimentation zone 11 by opening the valve of the first drain port 12. The device can also be used to pump out the waste liquid. Pump 7 pumps the cutting fluid above the conical sedimentation zone 11 inside the filter cylinder 1 into the outlet pipe 4. It then undergoes secondary filtration through the second filter screen 51 inside the T-type filter 5, removing fine impurities. The filtered cutting fluid then enters the adsorption cylinder 61. Six magnetic suction rods 65 inside the adsorption cylinder 61 attract residual suspended iron filings, iron powder, and other ferromagnetic impurities to the surface of the magnetic suction rods 65, achieving a three-stage filtration effect. Finally, the fluid is pumped by pump 7 to the cutting fluid supply port on the lathe, achieving a recycling effect. After a period of use, the magnetic adsorption mechanism 6 can be operated by closing the pump 7 and the outlet valve. By removing the fixing bolts on the cylinder cover 64, the operator can lift the magnetic suction rods 65 using the handle 67, scraping off the impurities adsorbed on the magnetic suction rods 65 and causing them to fall to the bottom of the adsorption cylinder 61. The waste liquid can then be discharged by opening the valve on the outside of the second drain port 66, achieving a quick and convenient cleaning of the magnetic suction rods 65.
