Description

Technical Field

[0001] The utility model relates to a core rod lubrication device. Background Art

[0002] At present, mandrel lubrication technology is crucial in the production process of hot-rolled seamless steel pipes. Lubricating the mandrel can reduce the wear on the surface of the mandrel, protect the inner surface of the seamless steel pipe, and facilitate the separation of the mandrel from the steel pipe after rolling. The commonly used lubrication method is to spray lubricant on the mandrel through a lubrication device. For example, a mandrel lubrication device is disclosed in a Chinese patent with a publication number of CN2897483Y, which can spray lubricant on the mandrel to lubricate the mandrel. However, after the lubricant is sprayed on the high-temperature mandrel, a large amount of mist will be generated. The existing lubrication device cannot collect and process the generated mist, causing the mist to escape into the workshop and then spread in the workshop, thereby causing the production environment in the workshop to deteriorate, visibility to decrease, and endangering the health of employees.

[0039] like Figures 1 to 3 As shown, a mandrel lubrication device comprises a suction device, an exhaust gas treatment device, at least one spray box 1 and a spray device 100 corresponding to the spray box 1;

[0040] The spray box 1 is provided with a feed port 2 and a discharge port 3, and the core rod is used to pass through the feed port 2 and the discharge port 3 and then pass through the spray box 1;

[0041] The spraying device 100 is installed in the corresponding spraying box 1, and the spraying device 100 is used to connect the lubricant and spray the lubricant on the core rod passing through the spraying box 1;

[0042] The spray box 1 is also provided with an exhaust port, the inlet of the suction device is connected to the exhaust port, and the outlet of the suction device is connected to the exhaust gas treatment device. The suction device is used to pump the mist in the spray box 1 to the exhaust gas treatment device for collection and treatment. Specifically, when the core rod that has completed the work passes through the spray box 1, the spray device 100 in the spray box 1 sprays the lubricant on the core rod that passes through the spray box 1, thereby lubricating the core rod. Since the core rod is still in a high temperature state after the work is completed, a large amount of mist will be formed in the spray box 1 after the lubricant is sprayed on the high-temperature core rod. At this time, the suction device pumps the mist in the spray box 1 to the exhaust gas treatment device for collection and treatment of the mist, thereby preventing the mist in the spray box 1 from escaping into the workshop, preventing the mist from spreading in the workshop and polluting the workshop environment, thereby improving the production environment and visibility in the workshop, and preventing the mist from being inhaled by employees, thereby avoiding harm to the health of employees.

[0043] In this embodiment, two spray boxes 1 are provided, and the core rod passes through the two spray boxes 1 in sequence. The spray device 100 corresponds to the spray boxes 1 one by one and is installed in the corresponding spray box 1 .

Among them, the recovery box 4 is also provided with a filtering device for filtering the lubricant in the recovery box 4. The specific structure of the filtering device is a prior art well known to those skilled in the art and will not be described in detail in this embodiment.

[0048] The inlet of the recovery pump 5 is connected to the recovery tank 4, and the outlet of the recovery pump 5 is connected to the storage container 6. The recovery pump 5 is used to pump the lubricant in the recovery tank 4 into the storage container 6;

[0049] The liquid level meter is installed in the recovery tank 4, and the liquid level meter is connected to the controller and is used to detect the liquid level signal in the recovery tank 4 and send it to the controller;

[0050] The controller is connected to the recovery pump 5 and is used to control the operation of the recovery pump 5 according to the liquid level signal sent by the liquid level meter; specifically, when the liquid level in the recovery tank 4 is higher than the working threshold, the controller controls the recovery pump 5 to start working, and when the liquid level in the recovery tank 4 is lower than the stop threshold, the controller controls the recovery pump 5 to stop working, thereby making the recovery pump 5 work intermittently, preventing the recovery pump 5 from being in a working state for a long time and causing a dry-running problem, thereby reducing the failure rate of the recovery pump 5; in this embodiment, the recovery pump 5 can be a diaphragm pump.

[0051] like Figure 3 As shown, the mandrel lubrication device may further include a liquid supply device corresponding to the spraying device 100 one by one, and the liquid supply device may include a storage tank 7 and at least one liquid supply pump 8;

[0054] like Figure 3 , 5 As shown, the liquid supply device may further include a pressure stabilizing tank 16 corresponding to the liquid supply pump 8, and the pressure stabilizing tank 16 is connected to the corresponding liquid supply pump 8 to ensure the stability of flow pressure;

[0055] The liquid supply device may further include an accumulator 11 corresponding to each of the liquid supply pumps 8, and the accumulator 11 is connected to the outlet end of the corresponding liquid supply pump 8;

[0056] The liquid supply device may further include an air heater 12 corresponding to the liquid supply pump 8 one by one, and the air heater 12 is connected to the corresponding liquid supply pump 8; specifically, in winter, when the liquid supply pump 8 is working, there is frost, which will affect the working condition of the liquid supply pump 8. The air heater 12 can prevent the liquid supply pump 8 from frosting when working in winter, thereby stabilizing the working performance of the liquid supply pump 8; in this embodiment, the liquid supply pump 8 can be a high-pressure pump.

[0057] like Figure 2 , 3 As shown, the spraying device 100 may include at least one spray ring 13, the spray ring 13 is installed in the corresponding spray box 1, and the core rod is used to pass through the inner side of the spray ring 13;

[0058] The outlet of the liquid supply pump 8 is connected to the spray ring 13 and is used to pump the lubricant into the spray ring 13;

[0059] The spray ring 13 is provided with a plurality of nozzles 14 distributed in sequence along the circumferential direction so that the lubricant in the spray ring 13 can be sprayed onto the core rod passing through the spray ring 13 through the nozzles 14 , and the excess lubricant on the core rod will drip into the spray box 1 .

[0060] In this embodiment, the spraying device 100 includes three spray rings 13, and the core rod passes through the inner sides of the three spray rings 13 in sequence;

[0061] Each of the spray rings 13 is provided with 6 nozzles 14 evenly distributed along the circumferential direction;

[0062] The nozzle 14 on the first spray ring 13 has a diameter of 0.15 mm and a spray fan angle of 40°;

[0063] The nozzle 14 on the second spray ring 13 has a diameter of 0.15 mm and a spray fan angle of 40°;

[0064] The nozzle 14 on the third spray ring 13 has a diameter of 0.3 mm and a spray fan angle of 40°;

[0068] In this embodiment, the exhaust gas treatment device is a cyclone spray tower, and the suction device is a negative pressure fan; specifically, the mist is formed by high-temperature atomization of the lubricant, and the cyclone spray tower can wash the inhaled mist to dissolve the mist in water. The circulating water in the cyclone spray tower is regularly discharged to the lubricant mixing station to recycle the lubricant for reuse, thereby saving costs.

[0069] In summary, when the core rod that has completed the work passes through the spray box 1, the spray device 100 in the spray box 1 sprays the lubricant on the core rod that passes through the spray box 1, thereby lubricating the core rod. Since the core rod is still in a high temperature state after the work is completed, a large amount of mist will be formed in the spray box 1 after the lubricant is sprayed on the high-temperature core rod. At this time, the suction device pumps the mist in the spray box 1 to the exhaust gas treatment device for collection and treatment of the mist, thereby preventing the mist in the spray box 1 from escaping into the workshop, preventing the mist from spreading in the workshop and polluting the workshop environment, thereby improving the production environment and visibility in the workshop, and preventing the mist from being inhaled by employees, thereby avoiding harm to the health of employees.
