The air in the bubbles or foam can promote the oxidation reaction of the cooling oil, accelerate the aging of the oil and the corrosion of the equipment. In addition, due to the presence of bubbles, the moisture in the cooling oil is more likely to react with the air to form acidic substances, increasing the risk of metal corrosion.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution: a defoaming device for cooling oil of an external cylindrical grinder, comprising: a defoaming mechanism 1, a fixing mechanism 2 is arranged at one end of the defoaming mechanism 1, the defoaming mechanism 1 comprises a hollow cylinder 11, a cyclone 12 is arranged inside the hollow cylinder 11, a foam collecting box 13 is arranged at the top of the cyclone 12, a positioning tube 14 is arranged on the inner side of the foam collecting box 13, a connecting tube 15 is arranged at the top of the positioning tube 14, a buckle cover 16 is arranged at the top of the connecting tube 15, a filter layer 17 is arranged on the inner wall of the top of the buckle cover 16, a connector 18 is arranged on the top of the filter layer 17, a dredging tube 19 is arranged at the bottom of the cyclone 12, an oil pump 110 is arranged at one end of the dredging tube 19, an oil cylinder 111 is arranged at one end of the oil pump 110, the inner wall of the hollow cylinder 11 and the cyclone 12 are connected to each other. The outer side of the cyclone 12 is fixedly connected, the outer side of the bottom end of the cyclone 12 is fixedly penetrated and fixed with the inside of the foam collecting box 13, the inner wall of the foam collecting box 13 is vertically corresponding to the bottom end of the alignment tube 14, the top of the alignment tube 14 is fixedly connected with the bottom end of the connecting tube 15, the top of the connecting tube 15 is connected with the buckle cover 16, the outer side of the buckle cover 16 is connected with the inner thread of the hollow cylinder 11, the top inside of the buckle cover 16 is vertically corresponding to the bottom of the filtering layer 17, the top of the filtering layer 17 is connected with the inside of the connector 18, the inner side of the connector 18 is corresponding to the depression of the buckle cover 16, the bottom of the cyclone 12 is connected with one end of the dredging tube 19, the other end of the dredging tube 19 is fixedly connected with one end of the oil pump 110, and the other end of the oil pump 110 is connected with one end of the oil cylinder 111.

[0026] In this embodiment, when the device is used, the connecting end of the oil cylinder 111 is interconnected with the oil pump 110, and then the oil pump 110 is started to extract the cooling head in the oil cylinder 111 and transmit it into the cyclone 12 through the dredging pipe 19. The cyclone 12 generates centrifugal force by rapid rotation. The centrifugal force inside the cyclone 12 is used to push the bubbles and foams upward, so that they float to the surface of the cooling oil, thereby ensuring the normal operation of the cooling system and avoiding the problems of foaming, oxidation and degradation of the cooling oil, thereby improving the cooling effect and stability. At this time, the separated bubbles and foams will remain in the foam collecting box 13. By connecting the connecting head 18 with the vacuum pump, a negative pressure will be generated inside the connecting pipe 15 under the action of the vacuum pump, and the bubbles and foams vertically corresponding to the foam collecting box 13 will be extracted. The bubbles and foams may carry impurities, microorganisms and other substances. When they exist in the liquid, they may cause product contamination. By separating and extracting the bubbles and foams, the risk of product contamination can be reduced.

[0027] Secondly, during the extraction process, the filter layer 17 can perform preliminary filtration to remove larger granular impurities and solid particles. The filter layer 17 can effectively prevent larger granular impurities and solid particles from entering the interior of the vacuum pump. In addition, by separating the buckle cover 16 from the hollow cylinder 11, the hollow cylinder 11 can be cleaned later.

[0030] In this embodiment, when placing the oil cylinder 111, it is first placed on the bottom plate 21, and then the U-shaped plate 23 is aligned with the alignment groove 22 and slid to the middle end of the bottom plate 21 to restrict and fix the oil cylinder 111. This fixing method can prevent the oil cylinder 111 from shaking, sliding or tilting during transportation, maintain the stability of the oil cylinder 111, and fix the oil cylinder 111 using the alignment groove 22 and the U-shaped plate 23, which can make the installation and removal of the oil cylinder 111 easier. This fixing method can quickly and accurately fix the oil cylinder 111 on the bottom plate 21, saving time and labor.

[0032] like Figure 1 - Figure 4As shown, when the utility model is used, according to the needs of the user, the connecting end of the oil barrel 111 is interconnected with the oil pump 110, and then the oil pump 110 is started to extract the cooling head in the oil barrel 111 and transmit it into the cyclone 12 through the dredging pipe 19. The cyclone 12 generates centrifugal force by rapid rotation, and the centrifugal force inside the cyclone 12 is used to push the bubbles and foam upward, so that they float to the surface of the cooling oil. At this time, the separated bubbles and foam will remain in the foam collecting box 13. By connecting the connecting head 18 with the vacuum pump, negative pressure will be generated inside the connecting pipe 15 under the action of the vacuum pump, and the bubbles and foam inside the vertically corresponding foam collecting box 13 will be extracted;

[0033] By aligning the U-shaped plate 23 with the alignment groove 22 and sliding it to the middle end of the bottom plate 21, the oil cylinder 111 is restricted and fixed. This fixing method can prevent the oil cylinder 111 from shaking, sliding or tilting during transportation, thereby maintaining the stability of the oil cylinder 111.
