Description

Technical Field

[0001] The present invention relates to the technical field of machining equipment, and particularly relates to a rapid oil-water separation device for the cutting fluid of a machine tool. Background Art

[0002] In the mechanical processing industry, cutting fluid is an essential necessity. When the machine tool is in the processing process, a large amount of other oil substances will inevitably be mixed into the water-based cutting fluid. These miscellaneous oils float on the surface of the cutting fluid, resulting in a large number of bacteria breeding, accelerating the deterioration and stench of the cutting fluid, causing corrosion of the machine tool and workpieces, shortening the service life of the cutting fluid, and a series of other phenomena. However, most of the existing traditional machine tools have the water tank set at the bottom of the machine tool. If it is necessary to clean the floating oil or replace the cutting fluid, the machine must be stopped and the protective cover removed, and the water tank dragged out, and it requires the cooperation of multiple people to complete, which is time-consuming and laborious, increases the downtime, and reduces the production efficiency. The related patents that have been published, such as CN116081765A and CN115318003A, although provide an oil-water separation device, both need to collect the cutting fluid separately for treatment and cannot continuously remove the floating oil without interrupting the processing. Modern manufacturing generally develops towards high efficiency, and the requirements for the stability of cutting fluid and the comprehensive efficiency of equipment are increasing day by day. The traditional offline cleaning mode has been difficult to meet the needs of modern factories for "continuous production and zero downtime". It is urgent to develop an oil-water separation device that can separate the floating oil on the surface of the water tank in real time during the operation of the machine tool, does not require the disassembly of the water tank, has a high degree of integration, and a high degree of automation.

[0039] Before the oil-water separation device of the present invention works, the oil storage box 8 is inserted into the outer box 1 through the roller slide rail 11. When the oil pouring port 82 of the oil storage box 8 abuts against the vertical arm of the L-shaped bracket 91, the torsion spring 93 is compressed, and the L-shaped bracket 91 rotates. When the oil storage box 8 is inserted in place, the vertical arm of the L-shaped bracket 91 contacts the proximity switch 94, and the liquid level sensor 96 on the horizontal arm also rotates and extends into the oil storage box 8. At this time, the proximity switch 94 is turned on, the electronic control component receives the signal of the proximity switch 94, the electronic control component controls the solenoid valve to open, the high-pressure gas enters the pneumatic diaphragm pump 6 through the solenoid valve, and the pneumatic diaphragm pump 6 starts to work.

[0040] The oil-water mixture on the surface of the machine tool water tank first enters the filter bottle 5 to filter impurities such as iron filings, and then the pneumatic diaphragm pump 6 pumps the filtered oil and water into the buffer bin 35, and then smoothly flows into the front bin 31. Due to the different densities of oil and water, the mixture flowing into the front bin 31 is separated for the first time. The floating oil on the upper layer is adsorbed on the two oil scraping discs 42, and is scraped off by the scraper 43 and flows into the middle bin 32 along the oil receiving inclined groove 44 and the oil leakage groove 341. The clean cutting fluid in the front bin 31 first flows into the mixing bin 33 from the thick pipe. When the flow rate in the front bin 31 is too large, the cutting fluid can also flow into the mixing bin 33 from the thin pipe to prevent the cutting fluid from overflowing when the flow rate in the front bin 31 is too large; the floating oil scraped into the middle bin 32 undergoes secondary separation, and the floating oil on the upper layer enters from the upper end of the adjusting sleeve 371 and flows out of the outer end oil outlet of the external thread pagoda 374 into the oil storage box 8. The height of the upper port of the adjusting sleeve 371 can be controlled by the adjusting handle 375, so as to control the liquid level in the middle bin 32, and further adjust the waste oil outflow speed; the lower layer of clean cutting fluid in the middle bin 32 flows into the mixing bin 33 through the overflow pipe 36. Finally, the cutting fluid in the mixing bin 33 returns to the machine tool water tank through the water outlet pipe 15. During the working period, ozone is introduced into the mixing bin 33 through the ozone interface pipe 343 on the inner box cover plate 34 to sterilize the treated cutting fluid in the mixing bin 33.

[0041] When the waste oil in the oil storage box 8 reaches the highest liquid level, the signal of the liquid level sensor 96 is transmitted to the electronic control component to control the oil-water separator to stop working, and the LED light 95 flashes to give an alarm reminder; when the upper cover 2 is opened, the plug pin shaft 102 rises under the action of the spring 103, the end of the plug pin shaft 102 leaves the waist-shaped connection hole 84, the oil storage box 8 can be pulled out of the oil storage bin, the pouring port 82 is separated from the L-shaped bracket 91, the proximity switch 94 disconnects the signal, the L-shaped bracket 91 rotates reversely under the action of the torsion spring 93, and the liquid level sensor 96 leaves the oil storage box 8.

[0042] The parts not detailed in the present invention are the prior art.
