Description
Technical Field
[0001] This utility model relates to the field of drying oven equipment, specifically a drying oven for lubricating oil production. Background Technology
[0002] With the development of the lubricating oil industry, the market demands increasingly higher performance and quality requirements for lubricating oils, especially in high-end fields such as aviation and precision machinery, where stricter standards are set for controlling the water content and impurities of lubricating oils. In the lubricating oil production process, drying ovens are mainly used to dry raw materials, semi-finished products, or finished products to remove moisture or other volatile substances, ensuring that the quality and performance of the lubricating oil meet the requirements.
[0003] Existing drying equipment typically evaporates the internal moisture of lubricating oil by heating it. However, when drying grease-type lubricating oils, due to the high viscosity of the grease, the internal moisture is difficult to evaporate effectively after heating and vaporization, resulting in poor drying effect, which in turn reduces the drying efficiency of the lubricating oil and reduces product quality.
[0004] Therefore, we provide a drying oven for lubricant production. Utility Model Content
[0005] The main objective of this invention is to provide a drying oven for lubricating oil production, which can effectively solve the problem mentioned in the background art that due to the high viscosity of lubricating grease, the moisture inside it is difficult to evaporate effectively after heating and vaporization, resulting in poor drying effect, which in turn reduces the drying efficiency of lubricating oil and reduces product quality.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A drying oven for lubricating oil production includes a drying oven, a partition fixedly installed at the lower interior of the drying oven, and a limiting ring fixedly installed on the inner wall of the drying oven above the partition. A reciprocating screw is vertically fixed above the center of the partition. A rotating disk is movably mounted between the limiting ring and the partition, and the bottom of the reciprocating screw passes through the center of the rotating disk. Four support rods are equidistantly mounted above the rotating disk. A stirring mechanism is movably mounted on each support rod and is also movably mounted on the reciprocating screw. A cover plate is mounted on each support rod. A gear two is provided at the top of the plate with its center through it, and alignment holes for engaging with the support rod are provided at equal intervals below the cover plate. A box cover is fitted and installed on the top of the drying box, and a tube embedded in the gear two is fixedly installed below the center of the box cover. A differential is fixedly installed on the box cover on one side of the tube, and a transmission gear one connected to the gear two is provided on the lower side of the differential. An air pump is fixedly installed on the box cover above the differential, and the differential is connected to the air pump. An air extraction pipe is connected through one side of the air pump, and the air extraction pipe is connected through the tube.
[0008] In the above scheme, preferably, the stirring mechanism includes a sliding sleeve nested on the support rod, with stirring blades fixedly connected to one side of the sliding sleeve, and a connecting sleeve nested and movably installed on the reciprocating screw, and the stirring blades are all fixedly connected to the connecting sleeve.
[0009] In the above scheme, preferably, a connecting shaft is fixedly installed at equal intervals on the inner side of the connecting sleeve, and a reciprocating block is movably connected to each connecting shaft, and the reciprocating block is movably connected to the reciprocating groove on the reciprocating screw.
[0010] In the above scheme, preferably, the drying oven is fixedly installed on the fixed base below, a servo motor is fixedly installed on one side of the fixed base, and a support platform fixedly installed on the fixed base is provided between the servo motor and the drying oven.
[0011] In the above scheme, preferably, the servo motor is embedded with a drive shaft, and the drive shaft passes through the support platform and is embedded in the drying chamber. The bottom of the drying chamber is provided with a heater fixedly installed on a fixed base. Heating wires are fixedly connected to both sides of the heater, and the heating wires are embedded in the inner wall of the drying chamber for heat exchange.
[0012] In the above scheme, preferably, a support plate is fixedly connected to the lower side of the partition, and a gear set is movably installed on the support plate, and the gear set is meshed and connected to the drive shaft for transmission.
[0013] In the above scheme, preferably, a gear disk is provided below the rotating disk, and the gear set is meshed and connected to the lower part of the rotating disk. An auxiliary wheel is equidistantly fitted and movably installed below the rotating disk, and the auxiliary wheel is fitted to the upper surface of the partition.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This drying chamber for lubricating oil production incorporates a differential, transmission gears, and an air pump. The differential connects to the air pump, while the transmission gear meshes with a second gear on the cover. When the air pump operates, the differential drives the first transmission gear to rotate, which in turn rotates the second gear and the cover, causing the stirring mechanism to agitate the lubricating oil. This design ensures continuous agitation of the lubricating oil during the air extraction process, accelerating moisture vaporization. Simultaneously, the air pump reduces the internal pressure, lowering the boiling point of water. These two factors work together to improve water evaporation efficiency, ensuring a highly efficient drying process and effectively enhancing the drying quality of the lubricating oil.
[0016] This drying chamber for lubricating oil production is equipped with a reciprocating screw, connecting sleeve, and reciprocating lever. When the rotating disk drives the support rod to rotate, the stirring blade rotates accordingly. At the same time, the connecting sleeve on the reciprocating screw makes a reciprocating motion due to the engagement and sliding of the reciprocating lever and the reciprocating groove. This causes the stirring blade to move up and down while rotating, making it easier for moisture to evaporate, improving the uniformity of heating of the lubricating oil, and accelerating the evaporation rate of moisture.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] like Figures 1-7As shown, in this embodiment, a drying oven for lubricating oil production includes a drying oven 5. A partition 10 is fixedly installed at the lower part of the interior of the drying oven 5, and a limiting ring 502 is fixedly installed on the inner wall of the drying oven 5 above the partition 10. A reciprocating screw 501 is vertically fixed above the center of the partition 10. A rotating disk 12 is movably installed between the limiting ring 502 and the partition 10, and the bottom of the reciprocating screw 501 passes through the center of the rotating disk 12. Four support rods 1201 are equidistantly installed above the rotating disk 12. A stirring mechanism 14 is movably installed on the support rods 1201, and the stirring mechanism 14 is movably installed on the reciprocating screw 501. A cover plate 13 is installed on the support rods 1201. A gear 1301 is provided above the center of the drying chamber 5, and a matching insertion hole 1302 is provided at equal intervals below the cover plate 13 to fit and align with the support rod 1201. A cover 6 is fitted and installed above the drying chamber 5, and an insertion tube 602 embedded in the gear 1301 is fixedly installed below the center of the cover 6. A differential 601 is fixedly installed on the cover 6 on one side of the insertion tube 602, and a transmission gear 6011 connected to the gear 1301 is provided on the lower side of the differential 601. An air pump 7 is fixedly installed on the cover 6 above the differential 601, and the differential 601 is connected to the air pump 7. An air extraction pipe 8 is connected through one side of the air pump 7, and the air extraction pipe 8 is connected through the insertion tube 602.
[0028] Specifically, with this configuration, during use, the rotating disk 12 is positioned and installed inside the drying oven 5 by the partition 10 and the limiting ring 502. Since the cover plate 13 is fitted onto the support rod 1201 via the alignment hole 1302, when the support rod 1201 rotates with the rotating disk 12, it drives the cover plate 13 to rotate synchronously. Because a second gear 1301 with a central through-hole is located above the cover plate 13, and the second gear 1301 is connected to the first transmission gear 6011, the synchronous rotation of the cover plate 13 drives the first transmission gear 6011 to rotate, thus... The transmission gear 6011 drives the differential 601 to work. Through the transmission connection between the differential 601 and the vacuum pump 7, the vacuum pump 7 performs vacuuming operation. Since the vacuum pipe 8 installed on the vacuum pump 7 is connected to the insertion pipe 602, and the insertion pipe 602 is embedded in the gear 1301, when the vacuum pump 7 operates, the water vapor that has been heated and evaporated in the lubricating oil in the box is extracted through the vacuum pipe 8, the insertion pipe 602 and the gear 1301. At the same time, the vacuuming operation of the vacuum pump 7 reduces the temperature of water evaporation, accelerates the drying process of the lubricating oil, and thus improves the drying efficiency and quality of the lubricating oil.
[0029] like Figures 1-7As shown, in this embodiment, the stirring mechanism 14 includes a sliding sleeve 1401 nested on the support rod 1201. A stirring blade 1402 is fixedly connected to one side of the sliding sleeve 1401. A connecting sleeve 1403 is nested and movably installed on the reciprocating screw 501, and the stirring blades 1402 are all fixedly connected to the connecting sleeve 1403. A connecting shaft 1404 is fixedly installed at equal intervals on the inner side of the connecting sleeve 1403. A reciprocating paddle 1405 is movably connected to the connecting shaft 1404, and the reciprocating paddle 1405 is movably connected to the reciprocating groove on the reciprocating screw 501.
[0030] Specifically, with this configuration, when the rotating disk 12 rotates, it drives the four support rods 1201 fixedly installed above to rotate synchronously. Since the sliding sleeve 1401 is nested on the support rods 1201, the stirring blade 1402 rotates accordingly to stir the lubricating oil in the drying chamber 5. Because the stirring blade 1402 is fixedly connected to the connecting sleeve 1403 movably nested on the reciprocating screw 501, and the reciprocating screw 501 is fixedly installed at the center of the partition 10, when the stirring blade 1402 rotates, it drives the connecting sleeve 1403 to rotate synchronously. When the connecting sleeve 1403 rotates around the reciprocating screw 501, the reciprocating block 1405 slides within the reciprocating groove. When the reciprocating block 1405 slides to the end of the reciprocating groove of the reciprocating screw 501, the reciprocating block 1405 changes direction on the connecting shaft 1404 due to the obstruction at the groove end. This causes the reciprocating block 1405 to cause the connecting sleeve 1403 and the stirring blade 1402 to reciprocate on the reciprocating screw 501, thereby improving the uniform heating efficiency of the lubricating oil during the heating process and increasing the evaporation rate of water in the lubricating oil.
[0031] like Figures 1-7 As shown, in this embodiment, the drying oven 5 is fixedly installed on the fixed base 1 below. A servo motor 2 is fixedly installed on one side of the fixed base 1, and a support platform 4 fixedly installed on the fixed base 1 is provided between the servo motor 2 and the drying oven 5. A drive shaft 3 is movably installed inside the servo motor 2, and the drive shaft 3 passes through the support platform 4 and is movably installed inside the drying oven 5. A heater 9 is fixedly installed on the fixed base 1 at the bottom of the drying oven 5. Heating wires 901 are fixedly connected to both sides of the heater 9, and the heating wires 901 are embedded in the inner wall of the drying oven 5 for heat exchange.
[0032] Specifically, with this setup, during use, the servo motor 2, support platform 4, drying chamber 5, and heater 9 are installed on the fixed base 1. The support platform 4 is installed to improve the stability of the servo motor 2 when driving the drive shaft 3 to rotate. By wrapping the heating wire 901 around the inner wall of the drying chamber 5, when lubricating oil such as grease is put into the drying chamber 5, the heating wire 901 heats the inside of the drying chamber 5 when the heater 9 is operating, so as to evaporate the moisture in the lubricating oil.
[0033] like Figures 1-7 As shown, in this embodiment, a support plate 11 is fixedly connected to the lower side of the partition 10. A gear set 1101 is movably mounted on the support plate 11 and is meshed with the drive shaft 3 for transmission. A gear disk is set below the rotating disk 12, and the gear set 1101 is meshed with the lower part of the rotating disk 12 for transmission. An auxiliary wheel 1202 is movably mounted at equal intervals below the rotating disk 12 and is attached to the upper surface of the partition 10.
[0034] Specifically, with this configuration, during use, the operation of the servo motor 2 drives the drive shaft 3 to rotate, and the rotation of the drive shaft 3 drives the gear set 1101 on the support plate 11 to rotate. Since the gear set 1101 is meshed and connected to the lower part of the rotating disk 12, the servo motor 2 drives the drive shaft 3 to rotate, thereby driving the rotating disk 12 to rotate synchronously. When the rotating disk 12 rotates, the auxiliary wheel 1202 installed below it reduces the friction between it and the partition plate 10, thereby assisting the smooth operation of the rotating disk 12.
[0035] It should be noted that when using this utility model as a drying oven for lubricating oil production, by installing the servo motor 2 on the fixed base 1, and cooperating with the support platform 4, drying oven 5, and heater 9, stable operation of the equipment can be achieved. The installation of the support platform 4 helps to improve the stability of the servo motor 2 when driving the drive shaft 3 to rotate. The operation of the servo motor 2 can effectively drive the drive shaft 3 to rotate, thereby causing the gear set 1101 on the support plate 11 to rotate. The rotating disk 12 can run smoothly by rotating synchronously with the drive shaft 3. The installation of the auxiliary wheel 1202 further reduces the friction between it and the partition 10. The heater 9 heats the lubricating oil by wrapping the heating wire 901 around the inner wall of the drying oven 5, evaporating the moisture in it. The rotation of the rotating disk 12 drives the four support rods 1201 above to rotate synchronously, and the stirring blade 1402 rotates accordingly to stir the lubricating oil in the drying oven 5. The reciprocating screw 501 is fixed to the center of the partition 10, and the stirring blade 1402... The rotation of 02 drives the connecting sleeve 1403 to rotate around the reciprocating screw 501. The reciprocating block 1405 slides in the reciprocating groove. When the reciprocating block 1405 slides to the end of the reciprocating groove, the obstruction on the connecting shaft 1404 causes it to change direction, thereby causing the reciprocating block 1405, the connecting sleeve 1403 and the stirring blade 1402 to reciprocate on the reciprocating screw 501. The rotating disk 12 is limited and installed in the drying oven 5 by the partition 10 and the limiting ring 502. The support rod 1201 rotates with the rotating disk 12. The cover plate 13 rotates synchronously, and the rotation of the cover plate 13 drives the transmission gear 6011 to rotate through the gear 2 1301, which in turn drives the differential 601 to work. The transmission connection between the differential 601 and the vacuum pump 7 enables the vacuum pump 7 to perform vacuuming operation. The vacuum pump 7 extracts the water vapor that has been heated and evaporated in the lubricating oil in the box through the vacuum pipe 8, the insertion pipe 602 and the gear 2 1301, while reducing the temperature of water evaporation and accelerating the drying process of the lubricating oil, thereby improving the drying efficiency and quality of the lubricating oil.
