[0019] The inner diameters of the gas collecting part 32 and the liquid storage part 33 are gradually reduced in the direction away from the cylindrical body 31. The lower end of the liquid storage part 33 is connected to a liquid outlet pipe 5, and a one-way valve 61 is installed on the liquid outlet pipe 5. A first solenoid valve 62 is installed on the third pipeline 10 of the three-way pipe 1. The first solenoid valve 62 is opened and closed synchronously with the one-way valve 61. A second solenoid valve 81 is installed on the air intake pipe 72. A third solenoid valve 82 is installed on the second pipeline 9 of the three-way pipe 1, which is opened and closed synchronously with the second solenoid valve 81.

[0020] When in use, first load the workpiece to be processed onto the adsorption fixture, and simultaneously open the second and third solenoid valves, so that the cavity in the adsorption fixture, the cutting oil recycling device and the central vacuum pump are connected as one;

[0021] When it is necessary to discharge the accumulated cutting fluid or cutting oil and other liquids to the outside, the second and third solenoid valves are closed at the same time and the one-way valve and the first solenoid valve are opened at the same time, and the air compressor is started to blow air from the upper end into the circulation recovery device of the cutting oil, and the positive pressure gas injected into the circulation recovery device of the cutting oil is used to discharge the accumulated liquid from the liquid outlet pipe at the lower end. Specifically, the liquid can be discharged into the oil tank of the corresponding machine to realize the recycling of the cutting oil and reduce the waste of oil and the generation of waste liquid.

[0022] The cylindrical body 31 is cylindrical.

[0023] The volume of the cylindrical body 31 is 13L.

[0024] The liquid outlet pipe 5 is used to be connected to the oil storage tank of the processing machine.

[0025] Embodiment 2: A cutting oil recycling device, comprising: a vertically extending cylindrical body 31, a gas collecting part 32 connected to the upper end of the cylindrical body 31, and a liquid storage part 33 connected to the lower end of the cylindrical body 31, a three-way pipe 1 is installed at the upper end of the gas collecting part 32, a first pipeline 2 is connected to the gas collecting part 32, a second pipeline 9 of the three-way pipe 1 is used to communicate with a central vacuum pump, and a third pipeline 10 of the three-way pipe 1 is used to communicate with an air compressor, and an air inlet hole 71 is provided on the side wall of the cylindrical body 31 near one end of the gas collecting part 32, and the other end of the air inlet pipe 72 connected to the air inlet hole 71 is used to communicate with an adsorption fixture;

[0026] The inner diameters of the gas collecting part 32 and the liquid storage part 33 are gradually reduced in the direction away from the cylindrical body 31. The lower end of the liquid storage part 33 is connected to a liquid outlet pipe 5, and a one-way valve 61 is installed on the liquid outlet pipe 5.

[0027] Turn on the central vacuum pump, clamp and fix the workpiece through adsorption force, and then perform conventional milling processing on the workpiece. During the milling process, a part of the cutting fluid or cutting oil used for auxiliary milling passes through the adsorption tube together with the gas into the cylindrical body for gas-liquid separation, so that the gas continues to enter the central vacuum pump through the pipeline after passing through the gas collecting part, while the cutting fluid or cutting oil accumulates in the liquid storage part. This not only avoids the cutting fluid or cutting oil mixing with the gas and entering the central vacuum pump, causing damage to the central vacuum pump and affecting the strength and stability of the adsorption fixture to clamp the workpiece, but also allows the cutting fluid or cutting oil to be recycled, greatly saving resources and reducing waste.

[0028] The cylindrical body 31 is cylindrical.

[0029] The gas collecting portion 32 and the liquid storage portion 33 are both in a conical funnel shape.

[0030] The volume of the cylindrical body 31 is 17L.

[0031] The working principle of the utility model is as follows:

[0032] When in use, first load the workpiece to be processed onto the adsorption fixture, and simultaneously open the second and third solenoid valves, so that the cavity in the adsorption fixture, the cutting oil recycling device and the central vacuum pump are connected as one;

[0033] The central vacuum pump is turned on, and the workpiece is clamped and fixed by adsorption force, and then the workpiece is subjected to conventional milling processing. During the milling process, a part of the cutting fluid or cutting oil used for auxiliary milling enters the cylindrical body through the adsorption tube together with the gas for gas-liquid separation, so that the gas continues to enter the central vacuum pump through the pipeline after passing through the gas collecting part, while the cutting fluid or cutting oil accumulates in the liquid storage part, which not only avoids the cutting fluid or cutting oil mixing with the gas and entering the central vacuum pump to cause damage to the central vacuum pump and affect the strength and stability of the adsorption fixture to clamp the workpiece, but also can recycle the cutting fluid or cutting oil, which greatly saves resources and reduces waste;

[0034] When it is necessary to discharge the accumulated cutting fluid or cutting oil and other liquids to the outside, the second and third solenoid valves are closed at the same time and the one-way valve and the first solenoid valve are opened at the same time, and the air compressor is started to blow air from the upper end into the circulation recovery device of the cutting oil, and the positive pressure gas injected into the circulation recovery device of the cutting oil is used to discharge the accumulated liquid from the liquid outlet pipe at the lower end. Specifically, the liquid can be discharged into the oil tank of the corresponding machine to realize the recycling of the cutting oil and reduce the waste of oil and the generation of waste liquid.

[0035] Further explanation is as follows:

[0036] In order to meet the production requirements of energy saving and efficiency improvement, the production workshop cancelled the use of small negative pressure equipment and switched to central negative pressure equipment. However, the use of central negative pressure equipment has caused the following new problems: the cutting oil used in the milling process will be adsorbed and cross-mixed with the oil used by other machines due to poor sealing of the adsorption fixture and seepage, and cannot be recycled or reused, resulting in excessive waste of oil products; in addition, the mixed waste liquid is a chemical, and improper treatment will cause great harm to the environment. Therefore, it is necessary to pay a fee to outsource to a qualified manufacturer for harmless treatment, which increases costs.

[0037] Take the A64-LOGO processing machine with 20 units in operation as an example. The normal loss is about 5L. After the central negative pressure equipment is introduced, the loss is about 20L, which exceeds 15L / day. The additional cost calculation is as shown in Table 1:

[0038]

[0039] To solve the above problems, a recovery device with a capacity of about 10L is added between the central adsorption tube and the adsorption fixture. During the processing, the oil seeping from the adsorption fixture is adsorbed into the container for storage. After the processing is completed, the solenoid valve signal is given through the machine I / O connector to inject positive pressure into the container, and the oil is discharged through the one-way valve at the bottom of the container and released back to the machine oil tank for circulation.

[0040] After installing the recovery device, the oil consumption of a single machine for vacuum adsorption product processing was reduced from an average of 20 liters / day to 5 liters / day, achieving the expected effect;

[0041] The renovation of the recovery devices has covered 320 units, saving a total of about 420,000 yuan per month in waste liquid treatment costs and the cost of purchasing oil products for excessive loss. In addition, the frequency of employees' refueling has been reduced from 6 times a day to 2 times a day, 10 minutes each time, reducing worthless activities by 40 minutes. There is no need to use waste oil barrels to collect and free up space, reducing the impact of oil running, bubbling, dripping, and leaking on the environment. The movement of forklifts moving waste oil barrels has also been reduced, eliminating certain safety risks.

[0042] When the above-mentioned cutting oil circulation recovery device is used, its.
