Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheel hub processing technology, and in particular to a centralized emulsion supply system. Background Technology
[0002] During the machining process of aluminum alloy wheels, CNC machine tools are required to turn the heat-treated black blanks. The turning process necessitates the use of emulsion for cooling and lubrication to prevent high-temperature sticking to the cutting tool. The emulsion also washes away aluminum chips, ensuring the surface finish of the workpiece. Wheel machining workshops typically have a centralized emulsion supply system for centralized dispensing and supplying emulsion to each CNC machine tool. This system achieves cleaning, cooling, and lubrication during machining, and the emulsion is then recycled to a waste tank. However, the recycled emulsion often contains hydraulic oil and guide rail oil in the recycling pit, causing floating oil to form on the surface of the emulsion tank. If this oil is not removed promptly, it will negatively impact the product's appearance and finish.
[0003] The existing emulsion supply system lacks efficient oil spill removal capabilities, resulting in uncontrolled emulsion supply quality. It requires dedicated personnel to manually clean the oil spill, leading to high labor intensity. Furthermore, the existing emulsion supply system necessitates separate supply pumps for the clean liquid tank and the sludge tank, resulting in complex power configurations and high energy consumption.
[0004] Therefore, developing a centralized emulsion supply system is an urgent problem to be solved. Utility Model Content
[0005] The purpose of this invention is to address the above-mentioned problems by providing a centralized emulsion supply system, which solves the problem that existing centralized emulsion supply systems cannot effectively handle floating oil on the surface of emulsions, and also solves the problems of complex power configuration and high energy consumption in existing centralized emulsion supply systems.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A centralized emulsion supply system includes a clean liquid tank for storing clean emulsion. The clean liquid tank is connected to a CNC machine tool via a supply pipeline. A supply pump is connected to the supply pipeline, and a return pipeline is connected to the supply pump. The return pipeline is connected to a negative pressure generator, and the negative pressure generator is connected to a negative pressure tank. The negative pressure tank is connected to an oil skimming device, which includes an oil skimming float installed in the clean liquid tank. The oil skimming float is connected to the negative pressure tank via an oil suction pipeline.
[0008] Preferably, the bottom of the negative pressure tank is provided with a drain valve for discharging the emulsion floating oil collected in the negative pressure tank.
[0009] Preferably, a filter is provided on the return pipeline for purifying and filtering the return emulsion.
[0010] Preferably, a backup pump is also provided corresponding to the liquid supply line and the return line, and the backup pump is connected to the liquid supply line and the return line respectively.
[0011] Preferably, it also includes a wastewater tank for treating the recycled emulsion, the wastewater tank being lined with filter paper for purifying and filtering the recycled emulsion, and the wastewater tank being connected to a clean liquid tank via a reverse supply pipeline.
[0012] Preferably, the reverse supply pipeline is connected to a negative pressure tank, and the automatic reverse supply of the recovered emulsion is achieved through the negative pressure formed by the negative pressure tank.
[0013] Preferably, solenoid valves are respectively installed on the reverse supply pipeline and the oil suction pipeline for opening and closing the reverse supply pipeline and the oil suction pipeline.
[0014] Preferably, the wastewater tank is equipped with a level gauge for detecting the level of the recycled emulsion, and the level gauge is communicatively connected to a solenoid valve.
[0015] The beneficial effects of this invention are as follows: This invention uses a negative pressure generator to automatically clean the floating oil on the surface of the emulsion, improving upon the inefficient handling of floating oil in traditional emulsion treatment systems. This eliminates the need for dedicated personnel to clean the floating oil and improves the quality of the emulsion supply. Simultaneously, the negative pressure tank enables automatic back-supply of the recovered emulsion, eliminating the need for a power source for emulsion recovery. The negative pressure tank can provide negative pressure to both the suction and back-supply lines, simplifying the structural configuration and reducing system development, manufacturing, and maintenance costs.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] like Figure 1-2 As shown, a centralized emulsion supply system includes a clean liquid tank 10 for storing clean emulsion. The clean liquid tank 10 is connected to a CNC machine tool via a supply pipeline 11. A supply pump 12 is connected to the supply pipeline 11 to supply emulsion to the CNC machine tool. The supply pump 12 is also connected to a return pipeline 13, which is connected to a negative pressure generator 20. The negative pressure generator 20 is connected to a negative pressure tank 21, which is connected to an oil float treatment device for treating the oil floating in the emulsion in the clean liquid tank 10. The oil float treatment device includes an oil skimming float 30 installed in the clean liquid tank 10, which is connected to the negative pressure tank 21 via an oil suction pipeline 31.
[0023] In use, the supply pump 12 starts, supplying the emulsion in the clean liquid tank 10 through the supply pipeline 11 to the CNC machine tool for cleaning, cooling, and lubrication during processing; the other pipeline supplies the emulsion to the negative pressure generator 20 through the return pipeline 13 and returns it to the clean liquid tank 10. The negative pressure generator 20 generates negative pressure during the emulsion flow, creating negative pressure in the negative pressure tank 21. The oil skimming float 30 connected to the negative pressure tank 21 floats on the surface of the emulsion, drawing the floating oil on the surface of the emulsion into the negative pressure tank 21, thus completing the automatic cleaning of the floating oil on the surface of the emulsion. This embodiment achieves automatic cleaning of the floating oil on the surface of the emulsion by generating negative pressure through the negative pressure generator 20, improving the problem of inefficient handling of floating oil in traditional emulsion treatment systems, eliminating the trouble of assigning dedicated personnel to clean the floating oil, and improving the quality of emulsion supply.
[0024] Preferably, the bottom of the negative pressure tank 21 is provided with a drain valve 22 for discharging the emulsion floating oil collected in the negative pressure tank 21.
[0025] Preferably, a filter 14 is provided on the return pipeline 13 for purifying and filtering the return emulsion, further improving the cleanliness of the emulsion and ensuring the effectiveness of use.
[0026] Preferably, a backup pump 15 is also provided corresponding to the supply line 11 and the return line 13, and the backup pump 15 is connected to the supply line 11 and the return line 13 respectively. When the supply pump 12 is abnormal, the backup pump 15 can be turned on to continuously supply emulsion to the supply line 11 and the return line 13, ensuring stable system operation.
[0027] In a preferred embodiment, the centralized emulsion treatment system further includes a wastewater tank 40 for treating and recovering the emulsion. The wastewater tank 40 is lined with filter paper 41 for purifying and filtering the recovered emulsion. The wastewater tank 40 is connected to a clean liquid tank 10 via a backfeed pipeline 42, allowing the purified and filtered recovered emulsion in the wastewater tank 40 to be fed back into the clean liquid tank 10, thus achieving a circulating supply of the emulsion.
[0028] Preferably, the reverse supply pipeline 42 is connected to the negative pressure tank 21, and the automatic reverse supply of the recovered emulsion is realized through the negative pressure formed by the negative pressure tank 21.
[0029] Preferably, solenoid valves 16 are respectively installed on the back-supply pipeline 42 and the oil suction pipeline 31 for opening and closing the back-supply pipeline 42 and the oil suction pipeline 31. When it is necessary to recover the emulsion and back-supply it to the clean liquid tank 10, the solenoid valve 16 of the back-supply pipeline 42 is opened, and the solenoid valve 16 of the oil suction pipeline 31 is closed at the same time, so that the negative pressure tank 21 acts on the back-supply pipeline 42 to draw the recovered emulsion into the waste liquid tank 40. This embodiment eliminates the need for a power supply for recovering the emulsion and realizes automatic back-supply of the recovered emulsion through the negative pressure tank 21.
[0030] Preferably, the wastewater tank 40 is equipped with a level gauge 43 for detecting the level of the recycled emulsion, and the level gauge 43 is communicatively connected to a solenoid valve 16. When the level gauge 43 detects that the liquid level in the wastewater tank 40 is lower than a certain level, it closes the solenoid valve 16 of the backfeed pipeline 42, ceasing the backfeed of emulsion to the clean liquid tank 10. Simultaneously, it opens the solenoid valve 16 on the oil suction pipeline 31, initiating the cleaning operation of the floating oil in the clean liquid tank 10. In this embodiment, the negative pressure tank 21 can provide negative pressure to both the oil suction pipeline 31 and the backfeed pipeline 42, simplifying the structural configuration and reducing manufacturing and maintenance costs.
