Description

Technical Field

[0001] This utility model relates to the field of lubricating oil refueling technology, specifically a pneumatic high-viscosity lubricating oil refueling device. Background Technology

[0002] High-viscosity lubricating oil is a common method of equipment lubrication, often used in high-temperature and heavy-load environments. Its viscosity can generally reach over 100, and some products can reach 300. Due to the high viscosity of the oil, it can only be supplied by a combination of oil pump and compressed air. The structure is complex and easily damaged. In addition, because the working environment is often high-temperature, replacement is inconvenient and cooling is required, which can cause production line shutdowns and restrict the continuous operation of the production line. Utility Model Content

[0003] The purpose of this invention is to provide a pneumatic high-viscosity lubricating oil refueling device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic high-viscosity lubricating oil refueling device, comprising:

[0005] The fuel tank is a cavity with an opening at the top, a sealing cover is installed at the top of the fuel tank, and a discharge pipe is installed at the bottom of the fuel tank.

[0006] A pressurization pipe is placed on one side of the oil tank. An air filter is installed at one end of the pressurization pipe, and a diversion pipe connected to the sealing cap is fixed in the middle of the pressurization pipe.

[0007] An elliptical limiting rod is fixed to the middle of the fuel tank. A cleaning plate is slidably connected to the outer side of the limiting rod and is slidably connected to the inner wall of the fuel tank for cleaning and scraping the inner wall of the fuel tank.

[0008] Preferably, a regulating valve is installed on one side of the air filter, and a pressurization pipe is fixedly connected to the output end of the regulating valve.

[0009] Preferably, solenoid valves are installed on the outer side of the diversion pipe and the middle part of the pressurization pipe.

[0010] Preferably, a pressure gauge is installed at the end of the pressurization pipe near the oil tank.

[0011] Preferably, a limiting ring is fixedly connected to the outer side of the limiting rod, and a spring is fixedly connected to the top of the cleaning plate, with the top of the spring fixedly connected to the top of the inner wall of the sealing cover.

[0012] Preferably, a water nozzle is fixedly connected to the middle of the cleaning plate, and a one-way valve for entry is fixedly connected to the input end of the water nozzle. The one-way valve is connected to the top water pipe joint of the flushing pipe sealing cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By connecting the pressurizing pipe to a high-pressure gas source, compressed air is used to pressurize the inside of the oil tank, causing the high-viscosity lubricating oil to be discharged from the discharge pipe under pressure. This effectively overcomes the disadvantage of poor fluidity of high-viscosity lubricating oil and achieves smooth oil supply. Solenoid valves are installed on the outside of the diverter pipe and in the middle of the pressurizing pipe. By controlling the opening and closing of the solenoid valves, the flow direction of compressed air can be flexibly controlled, realizing the switching between different operations such as pressurizing the oil tank and pressurizing the inside of the sealing cover, meeting different working needs. Opening the exhaust pipe at the top of the sealing cover releases the air pressure at the top of the cleaning plate. The spring reset pulls the cleaning plate upward along the limit rod to reset, preparing for the next cleaning. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 , 2As shown in Figure 3, this utility model provides a technical solution: a pneumatic high-viscosity lubricating oil refueling device, comprising: an oil tank 1 of a tank-type structure, the oil tank 1 bearing a pressure of 0.8 MPa and having an oil dipstick installed on its outer side, the oil tank 1 being a cavity with an opening at the top, a sealing cover 2 bolted to the top of the oil tank 1, an exhaust pipe installed on the top of the sealing cover 2, a sealing gasket installed between the oil tank 1 and the sealing cover 2, a discharge pipe 9 installed at the bottom of the oil tank 1, and a valve installed in the middle of the discharge pipe 9; a pressurization pipe 6 is fixed to one side of the oil tank 1. An air filter 3 is installed at one end of the pressurizing pipe 6. The air filter 3 is connected to a high-pressure gas source. A diversion pipe 4 connected to the sealing cover 2 is fixed to the middle of the pressurizing pipe 6. An elliptical limiting rod 13 is fixed to the middle of the oil tank 1. A cleaning plate 10 is slidably connected to the outside of the limiting rod 13. The cleaning plate 10 is a stainless steel plate with a rubber ring wrapped around its outside. The cleaning plate 10 is slidably connected to the inner wall of the oil tank 1 and is used to clean and scrape the inner wall of the oil tank 1.

[0020] It should be noted that in this embodiment, high-viscosity lubricating oil is stored in oil tank 1, and then the sealing cap 2 is tightly sealed on the top of oil tank 1. Then, the discharge pipe 9 is connected to the position where it needs to be filled. By pressurizing the inside of oil tank 1 through the pressure pipe 6, the high-viscosity lubricating oil is discharged from the discharge pipe 9 under the pressure.

[0021] In one embodiment, an regulating valve 14 is installed on one side of the air filter 3, and a pressurizing pipe 6 is fixedly connected to the output end of the regulating valve 14. Solenoid valves 5 are installed on the outer side of the diverter pipe 4 and the middle of the pressurizing pipe 6. A pressure gauge 7 is installed on the end of the pressurizing pipe 6 near the oil tank 1.

[0022] It should be noted that in this embodiment, the solenoid valves include a first solenoid valve fixed to the middle of the diverter pipe 4 and a second solenoid valve located outside the pressurizing pipe 6 and between the diverter pipe 4 and the oil tank 1. The pressure gauge 7 is located between the second solenoid valve and the oil tank 1. Since the pressurizing pipe 6 is connected to the oil tank 1, the pressure inside the oil tank 1 can be observed through the pressure gauge 7. Compressed air is connected to an air filter, and the operating pressure is adjusted by a regulating valve to match the oil supply. The pressure can be observed through the pressure gauge. The air filter is connected in series with a regulating valve and a drain valve to prevent water and dust in the compressed air from contaminating the lubricating oil.

[0023] In one embodiment, a limiting ring 12 is fixedly connected to the outer side of the limiting rod 13, and a spring 11 is fixedly connected to the top of the cleaning plate 10, with the top of the spring 11 fixedly connected to the top of the inner wall of the sealing cover 2.

[0024] It should be noted that in this embodiment, the cleaning plate 10 is in contact with the limiting ring 12 under the tension of the spring 11, thereby sealing the top of the oil tank 1 through the cleaning plate 10, making the area between the sealing cover 2 and the cleaning plate 10, and the area between the oil tank 1 and the cleaning plate 10, two independent areas. When the lubricating oil inside the oil tank 1 is filled and it is necessary to scrape the inner wall, the solenoid valve 2 in the middle of the pressurizing pipe 6 is closed, and the solenoid valve 1 in the middle of the diversion pipe 4 is opened, so that the high-pressure gas enters the diversion pipe 4 through the air filter 3 and the regulating valve 14, and finally into the sealing cover 2, thereby pressurizing the inside of the sealing cover 2. Under the action of pressure, the cleaning plate 10 moves downward along the limiting rod 13. At the same time as the limiting rod 13 moves downward, it stretches the spring 11, and the lubricating oil on the inner wall is scraped downward through the cleaning plate 10. When it is necessary to reset the cleaning plate 10, the exhaust pipe at the top of the sealing cover 2 is opened to release the air pressure at the top of the cleaning plate 10. Spring 11 resets the cleaning plate 10 by pulling it upward along the limit rod 13.

[0025] In one embodiment, a water nozzle 15 is fixedly connected to the middle of the cleaning plate 10, and a one-way valve 16 for entry is fixedly connected to the input end of the water nozzle 15. The one-way valve 16 is connected to the top water pipe joint of the flushing pipe 8 sealing cap 2.

[0026] It should be noted that, in this embodiment, when it is necessary to clean and wash the inside of the fuel tank 1, the cleaning plate 10 is driven downward to the bottom of the fuel tank 1, and then the solvent-based cleaning agent is injected into the fuel tank 1 through the flushing pipe 8, the one-way valve 16 and the spray nozzle 15 via the water pipe connector. In this way, the solvent-based cleaning agent reacts with the residue on the inner wall of the fuel tank 1, thereby cleaning the inside of the fuel tank 1. After cleaning, it can be discharged through the drain pipe 9.
