The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The following describes in detail a floating oil removing device for cutting fluid centralized processing according to a specific embodiment of the present invention with reference to the accompanying drawings. Fig. 1 and fig. 2 show the oil slick clearing device for the centralized processing of cutting fluid of the present invention, wherein the cutting fluid 11 of a plurality of devices is collected in the water tank 10, and the oil slick and other solid impurities are floating on the cutting fluid 11. The skimmer 20 is disposed in the water tank 10 and floats on the surface of the cutting fluid 11; the liquid inlet of the filter 30 is connected with the suction pipe 23 on the skimmer 20 by a hose 31, and the filter 30 is fixed on the side wall of the shell of the separation box 40; the diaphragm pump 41 is fixed at the bottom of the outside of the separation box 40, wherein the input port of the diaphragm pump 41 is in butt joint with the liquid outlet of the filter 30, the output port is connected with a liquid inlet pipe, and the liquid inlet pipe passes through a round hole at the bottom of the separation box 40 and enters the inside of the separation box 40. It should be noted that the mixture of the cutting fluid 11 collected by the skimmer 20 enters the separation box 40 for sealing, so as to ensure no leakage.
As shown in fig. 2-4, skimmer 20 includes quad float 21, skimmer box 22, suction tube 23, shaft 24, set top thread 25 and hemmed opening 26. The four-connection floating ball 21 has a central symmetrical structure and consists of a cross connecting rod and four floating balls, the four floating balls are respectively fixed at the four ends of the cross connecting rod, a hollow pipe is vertically arranged at the cross connecting position of the cross connecting rod, and the floating balls are made of light corrosion-resistant materials and have good floating capacity. Through holes can be arranged in the direction of the four end parts of the cross connecting rod perpendicular to the plane of the cross connecting rod, corresponding internal threads are processed on the floating balls, and the cross connecting rod is connected with the four floating balls by screws. The suction pipe 23 is longer than the hollow pipe, penetrates through the hollow pipe, and has two ends extending out of the hollow pipe, wherein one end is connected with the hose 31; the outer wall of hollow tube is equipped with location jackscrew 25, and location jackscrew 25 stretches into inside the hollow tube. The skimmer box 22 has an upper opening with one side wall provided with a hem opening 26, the hem of the hem opening 26 being planar. Round holes are correspondingly processed on two adjacent side faces of the folded edge opening 26, the round holes are higher than the folded edge in the vertical direction, the shaft 24 is hinged with the two adjacent side faces of the folded edge opening 26 through the round holes, and the shaft 24 is parallel to the folded edge. The other end of the suction pipe 23 extends from the upper opening of the skimmer box 22 through the shaft 24 into the interior of the skimmer box 22 and is welded to the shaft 24.
It should be noted that when the shaft 24 is mounted on the skimmer box 22, it is placed on the page of the cutting fluid 11, with the folds of the fold opening 26 remaining parallel to the page and slightly above the fluid level. Because shaft 24 is hinged to skimmer box 22, the folds remain parallel to the liquid surface at all times when skimmer 20 is placed in cutting fluid 11. The hollow pipe position is adjusted and positioned by the positioning jackscrew 25, and the hem of the hem opening 26 is ensured to be flush with the liquid level of the cutting fluid 11. The skimming box 22 and the shaft 24 can rotate relatively, and when the liquid level fluctuates, a large amount of cutting fluid is prevented from flowing in the process of skimming floating oil. The skimmer box 22 is preferably 100mm high, the straw 23 extends into the skimmer box 22 preferably 50mm deep, and the hem opening 26 is preferably 10mm from the top of the skimmer box. Because the quadruple floating ball 21 has good floating capacity, the sinking height of the skimmer 20 can be ignored when the mixture of the cutting fluid 11 containing floating oil enters the skimmer box 22.
As shown in fig. 1, an outlet pipe 42 and a return pipe 46 are respectively provided above both side walls of the separation tank 40, and the lowest heights of the openings of the outlet pipe 42 and the return pipe 46 in the separation tank 40 are the same. And the other end of the return pipe 46 is connected to the inside of the water tank 10 to form a return flow. An oil separation plate 45 is obliquely arranged in the separation box 40, the oil separation plate 45 is connected with the top and the side wall of the separation box 40, the interior of the separation box is divided into a cutting fluid separation area 43 and a floating oil separation area 44, the bottoms of the cutting fluid separation area 43 and the floating oil separation area 44 are communicated, and a liquid inlet pipe of an output port of the diaphragm pump 41 is connected to the floating oil separation area 44. The outlet pipe 42 is located in the area of the floating oil separating area 44 and the return pipe 46 is located in the area of the skimming separating area 43. The separation tank 40 has a small size and can be directly mounted on the water tank 10.
During operation, the floating oil removing device for the cutting fluid centralized treatment of the utility model is installed in place. Since the oil slick has a density lower than that of the cutting fluid 11, the oil slick floats on the surface of the cutting fluid 11. Because the hem of hem opening 26 is level with the surface of cutting fluid 11, oil slick will flow down hem opening 26 into skimmer 20. The diaphragm pump 41 is opened, and the mixture of the cutting fluid 11 in the skimmer 20 enters the filter 30 through the hose 31, so that the filter 30 can effectively remove the particulate impurities in the floating oil. The diaphragm pump 41 is operated at a slow speed, and the cutting fluid 11 containing a large amount of floating oil enters the floating oil separating zone 44 in the separation tank 40 to raise the liquid level in the separation tank. Because of different densities, the floating oil floats upwards, the floating oil is separated into a floating oil separation area 44 by an oil separation plate 45, the floating oil flows into a waste liquid barrel through an outlet pipe 42, the cutting liquid 11 enters a cutting liquid separation area 43 through the bottom of the separator 40 and flows back to the standing water tank 10 through a return pipe 46.
It should be noted that the separation box 40 can be divided into two cavities, and the diaphragm pump 41 can also be arranged in the lower end of the separation box 40; the diaphragm pump 41 may also be mounted below the outer side wall of the separation tank 40. The cleaner body 40 and the oil separation plate 45 are both made of stainless steel. The diaphragm pump 41 is a machine body with small power and treatment capacity of 25H/L, the power is about 25-30W, the running speed is low, the liquid in the separation box 40 is in a steady flow state, and the suction speed of the diaphragm pump 41 is always larger than or equal to the speed of the skimming box 22 for collecting the cutting liquid 11 containing a large amount of floating oil, so that the skimming box 22 cannot overflow the floating oil. The diaphragm pump 41 has no shaft seal leakage, good passing performance, long-time dry breathing and automatic start and stop after overload.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
