Description

Oil water treatment device

The present invention provides an oil-water treatment device, in particular to a method for generating a vacuum suction force by using an auto-circulating fluid with an aspirator or a liter tube, and sucking the oil slick of a cutting fluid collecting tank to the vacuum suction force to The oil-water separation tank performs oil-water treatment device for oil-water separation.

According to the CNC metal working machine, when cutting or turning, in order to reduce the high temperature generated by the cutting tool when working on the workpiece, and to provide proper lubrication, the cutting fluid is usually sprayed on the cutting tool and the workpiece to be processed. The contact position is lowered and lubricated to prevent damage to the cutting tool or the precision of the workpiece to be processed. Please refer to the first figure, the used cutting fluid will be collected and gathered at the bottom of the metal processing machine 10 In the cutting fluid collecting tank 11, the cutting fluid is pumped upward by a pumping pump 12, and then sent to the processing station via the conveying pipeline 13 to cool and lubricate the cutting tool and the workpiece (not shown). During the processing, the cutting fluid will be mixed with some oil, and too much oil will produce both oxygen-consuming and anaerobic bacteria. When the bacteria in the cutting fluid accumulate to a considerable amount, the cutting fluid will have an unbearable smell. The taste is generated, and the hygienic conditions of the working environment are low and unbearable. At the same time, if the cutting fluid is inadvertently contaminated, it may cause skin irritation.

For the processing equipment of the processed cutting waste liquid, such as the Taiwan Patent No. M415739 patent, the floating disk is suspended on the cutting waste liquid, and the floating disk has a liquid inlet pipe and a liquid discharge pipe, and the liquid inlet pipe Providing a flow of the cutting waste liquid into the floating tray, the liquid discharging tube Connected to the liquid inlet pipe, and a pump is mounted on the oil-water separation barrel, the pump is connected to the liquid discharge pipe and the oil-water separation barrel by a communication pipe for extracting the cutting waste liquid To the oil and water separation tank.

Although the above-mentioned oil-water separation device can be used to separate the cooling water and the cutting oil in the cutting waste liquid, it has the following defects:

First, because the pump is a self-priming pump, all self-priming pumps rely on the precision meshing and sealing of each part to prevent the expected use function. Therefore, the difficulty of the parts must be precisely produced and assembled. Higher, the cost is relatively higher.

Second, because the pump is a gear-type pump and will self-prime, intermittently inhaling water or air can work, but these gears must be precisely meshed to not leak, and can generate vacuum suction, but the cutting fluid The oil slick on the surface of the workpiece is doped with iron scraps, cast iron ash, dust and other impurities on the work site. When the oil containing impurities is sucked into the pump, impurities will cause wear between the gears. Increasing the backlash may also cause self-priming pump leakage.

3. When the oil slick is not a very good liquid oil, but is a sludge or a saponified oil like a bean flower, it may cause the floating plate suction port to be blocked, or the floating plate may be tilted by the discharge pipe. The suction port of the floating plate may not absorb the oil and water, only the air is sucked. If the gear pump is continuously operated for several minutes, if no oil or water is sucked into the cooling and lubrication, the heat may be stuck or even damaged.

Based on the shortcomings of the above-mentioned various oil-water separation devices of the Taiwan Patent No. M415739 patent, the creator has made great efforts to study and produce sample tests. After repeated tests and improvements, the following creative purposes have been achieved. The creation of this is a twin.

That is, the main purpose of the creation is to continuously circulate the cutting fluid in the oil-water separation tank through a circulating conveying pipeline by a pump, and to match one of the suction or the venturi with the circulating conveying pipeline, and the cutting fluid The suction generated by the suction or the tube is connected to the oil absorbing device in the cutting fluid collection tank of the metal working machine by another drawing line, and the oil slick of the cutting fluid collecting tank of the metal working machine is extracted to The oil-water separation in the oil-water separation tank can greatly reduce the oil slick in the cutting fluid collection tank of the metal processing machine. The oil slick located in the upper layer of the treated oil-water separation tank can be discharged to the outside of the oil-water separation tank for collection. The cutting fluid is then sent back to the cutting fluid collection tank of the metalworking machine for reuse, thereby solving the many disadvantages of using the self-priming pump to absorb the oil.

For the purpose of the above creation, the structural feature of the creation is that the oil water treatment device comprises at least an output line of a suction or liter tube, a drawing line, a slick suction, an oil water separation tank, and a pump. The output line is connected to the pump, and the pump can take the cutting fluid in the oil-water separation tank and discharge it from the outlet end of the output line to the oil-water separation tank to form a circulating flow loop, the suction or The literary pipe system is connected to the oil sump by drawing the pipeline, and the oil sump is placed in another cutting fluid collecting tank, when the fluid flows through the suction or the creel, due to the suction or the literary tube One of the partial flow channels is formed to reduce the diameter. According to the law of Ebony's efforts, the suction or the text tube generates a suction force to draw the oil in the cutting fluid collecting tank to the suction through the drawing line and the oil absorbing device. In the vessel or the venturi, the oil and water are separated from the outlet end of the output line to the oil-water separation tank; thereby, the disadvantages of using the self-priming pump to absorb the oil slick are solved, and more importantly, , Floating oil collecting tank for suction of cutting fluid, is the need to deploy a dedicated self-priming gear pump, and eliminating the acquisition of the self-priming gear pump and future maintenance costs.

From the above description, it can be seen that the oil-water treatment device 20, 20A of the present invention does not need to use a gear self-priming pump as a power source for sucking oil, but only needs to be powered by a general pump 40 or a submersible pump 40A. The source can be used, thereby eliminating the cost of the self-priming pumping of the gear and the cost of maintenance in the future, and using the cutting fluid 213 of the oil-water separation tank 21 as the liquid source of the circulation circuit instead of By taking the cutting fluid at the same place, it can ensure that the source of the liquid is not scarce, and at the same time, it is ensured that the suction device 31 or the text tube 70 can always maintain the suction force, and the oil floating of the cutting fluid collecting tank 11 can be continuously taken, and the cutting fluid is solved.
