Description

Technical Field

[0001] The utility model relates to the technical field of quartz rod punching, in particular to a punching machine cooling oil circulation filtering device. Background Art

[0002] The quartz glass rod is a coaxial cylinder. In the production of polarization-maintaining optical fiber, the quartz glass rod needs to be double-holed first, then embedded with a stress rod and melted together. Finally, the rod is formed into a whole and sent to the drawing tower for polarization-maintaining optical fiber drawing.

[0003] The quartz glass drilling machine works as follows: a motor drives the rotary drill bit, while a pressure foot applies pressure, causing the drill bit to penetrate the quartz glass surface and form a hole. During the drilling process, the drill automatically advances, while cooling oil is supplied through the cutter bar and cutter head to ensure the stability and accuracy of the drill bit.

[0004] The function of the punching machine cooling oil is: since the punching machine head will generate a lot of heat and fine quartz powder during the process of rotating and cutting quartz glass, cooling oil needs to be introduced to take away the heat and powder generated, thereby ensuring the punching quality and equipment stability.

[0005] Currently, quartz glass punches use expensive imported cooling oil. Conventional punch filters are unable to filter the extremely fine quartz powder (nanoscale) produced by grinding. Conventional punches use high-precision filters, which can cause oil blockage over time, requiring manual unclogging and component replacement to restore normal operation. Using low-precision filters, however, can lead to particulate matter in the cooling oil, affecting the inner surface finish (smoothness) of the punch rod during the punching process and even causing wavy lines on the inner surface, resulting in poor melt shrinkage and ultimately, the quality of the finished optical fiber.

A plurality of adsorption filter balls 7 and a first liquid level sensor 404 are provided at the bottom of the adsorption box 8. The bottom of the adsorption box 8 is connected to the second still box 11 through a second pipeline 21. The second still box 11 is provided with a second liquid level sensor 405. The second still box 11 is connected to the centrifugal filtration system through a third pipeline 22.

[0024] In the preferred embodiment, the ultrasonic cleaning system includes an ultrasonic cleaning machine 10, which is connected to the top of the air drying box 14 through a third solenoid valve 403, and the bottom of the air drying box 14 is connected to the adsorption box 8. A movable baffle 12 and an electronically controlled sensor device 13 are provided in the air drying box 14. The adsorption box 8 is connected to the top of the ultrasonic cleaning machine 10 through an air duct 23, and a blower 9 is provided on the air duct 23.

[0025] In a preferred embodiment, the centrifugal filtration system includes a centrifuge 16 connected to the third pipeline 22 at its feed end. The centrifuge 16 is provided with a clean oil tank 17, an oil outlet 18 and a centrifugal filter layer 19. The third pipeline 22 is provided with an oil pump 15.

[0026] In a preferred embodiment, the sponge grid layer 2 and the filter paper grid layer 3 are arranged in a zigzag pattern.

[0027] Example 2:

[0028] like Figure 1 The working principle of the utility model is as follows: the punching machine oil outlet 1 passes the cooling oil mixed with particles into the first static box 4, first passes through the sponge grid layer 2, and is filtered by the sponge to remove large particles (such as glass residues, etc.) in the coolant. At the same time, the cooling oil is infiltrated and precipitated through the sponge to reduce the impact of the oil pressure. The precipitated cooling oil will slowly drip into the filter paper grid layer 3, pass through the filter paper, and perform primary filtration on the cooling oil. The filtered cooling oil enters the bottom of the first static box 4, and the deposited cooling oil will enter the adsorption filtration system.

[0029] The cooling oil after primary filtration enters the oil distributor 5 pipeline through the first solenoid valve 401, and is distributed through the various spray nozzles 6 on the pipeline and drips into the bottom of the adsorption box 8. At this time, the adsorption filter balls 7 placed at the bottom will fully contact with the cooling oil, adsorbing the water and impurities in the cooling oil to ensure the purity of the cooling oil.

[0030] When the oil level in the adsorption box 8 reaches the level marked by the first liquid level sensor 404, the second solenoid valve 402 will open, and the cooling oil will be affected by gravity and enter the second static box 11 through the oil outlet at the bottom of the adsorption box 8; according to the time setting, the blower 9 will be turned on at a fixed time, and the adsorption filter balls 7 at the bottom of the adsorption box 8 will be sucked in through the exhaust end pipe of the blower 9. The adsorption filter balls 7 are affected by the wind and enter the ultrasonic cleaning machine 10 from the outlet end of the blower 9. When all the adsorption filter balls 7 enter the cleaning machine, ultrasonic cleaning begins to separate impurities in the cleaning balls;

[0031] Then the blower 9 stops working, the second solenoid valve 402 is closed, the electric-controlled magnetic valve of the electric-controlled sensor device 13 is powered off, the movable baffle 12 will separate and open, the dried adsorption filter balls 7 stored in the air drying box 14 will enter the bottom of the adsorption box 8, and the first solenoid valve 401 will open again to start a new round of adsorption and filtration.

[0032] The ultrasonic cleaning machine 10 is connected to the air drying machine at the bottom through the third solenoid valve 403 pipeline. After the ultrasonic cleaning machine 10 completes cleaning, the adsorption filter balls 7 are placed at the bottom through the cleaning agent separation function of the ultrasonic cleaning machine 10. If this function is not available, the adsorption filter balls can also be manually removed and placed in the air drying box 14. The third solenoid valve 403 is opened, and the cleaned adsorption filter balls 7 will enter the air drying box 14 through the pipeline. The air drying box will start, and after the adsorption filter balls 7 are completely air-dried, they are placed at the bottom waiting for use.

[0033] The cooling oil entering the second static tank 11 will start the oil pump 15 through the signal of the second liquid level sensor 405. The cooling oil will enter the centrifuge 16 through the oil outlet of the oil pump 15. When the oil pump stops, the centrifuge 16 will start working. The high-speed rotating impeller will completely separate the particles in the cooling oil from the oil. The clean oil passes through the centrifugal filter layer 19 on the outer wall and slowly leaches out due to gravity and then enters the clean oil tank 17 at the bottom of the centrifuge. At this point, pure perforated cooling oil can be obtained.

[0034] Finally, through the action of the punching machine oil pump, the clean cooling oil enters the punching machine from the oil outlet 18 of the clean oil tank 17, completing the circulation of the entire system.

[0035] The beneficial effects of the utility model are as follows: the multi-stage filtration method abandons the traditional filter mode and removes tiny particles in the cooling oil through self-infiltration, adsorption and centrifugal methods; the adsorption filtration is self-cleaning, maintaining a stable and efficient adsorption filtration effect and stabilizing the filtration cycle quality; the overall structure of the device is stable and reasonable, the operation is convenient and efficient, and it is highly practical.
