Abstract
Description
Technical Field
[0001] This utility model relates to the field of lubricating oil production technology, and in particular to a defoaming device for lubricating oil production. Background Technology
[0002] In the production process of lubricating oil, foam is often generated because air or gas in the liquid is injected and surrounded by surfactants (such as additives, emulsifiers, etc.), forming a foam structure. These foams can affect the stability of the production process, reduce product quality, and even cause equipment failure.
[0003] Therefore, defoaming of lubricating oil is an essential piece of equipment in the lubricating oil production line. The main function of defoaming is to effectively eliminate or suppress foam in lubricating oil and ensure the smooth operation of the production process. Adding defoamer to lubricating oil is a common defoaming method. Defoamer can reduce the surface tension of foam, destroy the foam structure, and cause the foam to break.
[0004] However, existing defoaming devices require the addition of a certain amount of defoamer to the container containing lubricating oil during defoaming. The addition method is mostly manual, resulting in insufficient dispersion of the defoamer entering the container and a small contact area with the foam, which reduces the defoaming efficiency. Utility Model Content
[0005] The purpose of this invention is to solve the problem that the defoamer is often added manually, resulting in insufficient dispersion of the defoamer in the container and a small contact area with the foam, which reduces the defoaming efficiency. Therefore, this invention proposes a defoaming device for lubricating oil production.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A defoaming device for lubricating oil production includes a tank body with a nozzle inside. It also includes a connecting pipe rotatably mounted inside the tank body via a rotating pipe, wherein a conversion head is fixedly connected to the connecting pipe, and the nozzle is mounted below the conversion head. A drive unit for driving the rotating pipe to rotate is provided on the tank body. A feed pipe is fixedly mounted above the tank body, wherein the rotating pipe is rotatably connected to the feed pipe.
[0008] To drive the nozzle to rotate, preferably, the driving unit includes a motor fixedly connected to the top of the tank, the output end of the motor is fixedly connected to a rotating shaft, and bevel gears are fixedly connected to both the rotating shaft and the rotating tube, with the two bevel gears meshing together.
[0009] To add defoamer in a measured amount, preferably, a metering pump is fixedly installed on the top of the tank, the feed pipe is fixedly installed at the output end of the metering pump, and a delivery pipe is fixedly connected to the input end of the metering pump, with the delivery pipe fixedly connected to the tank.
[0010] To enable the nozzle to vibrate up and down, preferably, the connecting pipe is slidably connected to the rotating pipe, a spline is fixedly connected to the circumferential surface of the rotating pipe, the spline is slidably connected to the connecting pipe, a fixed seat is fixedly connected to the rotating pipe, and a guide rod is fixedly connected to the top of the conversion head. The guide rod is slidably connected to the fixed seat, a limit plate is fixedly connected to the top of the guide rod, a limit groove is formed inside the fixed seat, the limit plate is slidably connected to the inner wall of the limit groove, and a spring is fixedly connected between the bottom of the limit plate and the inner wall of the limit groove.
[0011] In order to drive the nozzle to vibrate up and down while rotating, preferably, a connecting rod is fixedly connected to the top of the conversion head, the end of the connecting rod away from the conversion head is set as a hemisphere, and an arc-shaped protrusion is fixedly connected to the inner wall of the tank, the arc-shaped protrusion being arranged on the rotation path of the connecting rod.
[0012] In order to drive the stirring rod to rotate and stir the defoamer and lubricating oil, preferably, the bottom of the conversion head is fixedly connected to the stirring rod.
[0013] Compared with the prior art, this utility model provides a defoaming device for lubricating oil production, which has the following beneficial effects:
[0014] 1. This defoaming device for lubricating oil production introduces defoamer into the tank through the feed pipe, which then passes through the rotating pipe, connecting pipe, and conversion head, and is sprayed into the tank by the nozzle. This replaces manual addition. The rotating pipe is driven by the drive unit, and the nozzle is driven to rotate by the connecting pipe and conversion head. This results in more dispersed defoamer and a larger contact area with the foam, thus improving defoaming efficiency.
[0015] 2. This defoaming device for lubricating oil production, through the setting of a connecting rod, during the rotation of the nozzle, the conversion head drives the connecting rod to rotate. When the connecting rod passes the arc-shaped protrusion, it is squeezed by it, causing the connecting rod to drive the connecting pipe down through the conversion head. At the same time, the guide rod drives the limiting plate to slide down along the limiting groove and compress the spring. After the spring returns to its original position, the guide rod drives the conversion head to rise, which in turn causes the nozzle below it to continuously shake up and down, making the defoamer more dispersed and further improving the defoaming efficiency.

[0023] Example:
[0024] Reference Figures 1-4 This utility model provides a defoaming device for lubricating oil production, including a tank 1 for storing lubricating oil, with nozzles 4 arranged inside the tank 1. The number of nozzles 4 is 6-20, and the preferred number in this application is 15. It also includes: a connecting pipe 202, which is rotatably installed inside the tank 1 via a rotating pipe 201. A conversion head 203 is fixedly connected to the connecting pipe 202, and the nozzles 4 are installed below the conversion head 203. A driving part for driving the rotating pipe 201 to rotate is provided on the tank 1. A feed pipe 5 is fixedly installed above the tank 1 for conveying defoamer. The rotating pipe 201 is rotatably connected to the feed pipe 5.
[0025] During operation, the defoamer is fed into the tank 1 through the feed pipe 5, the rotating pipe 201, the connecting pipe 202 and the conversion head 203, and then sprayed into the tank 1 by the nozzle 4, replacing manual addition. The rotating pipe 201 is driven to rotate by the drive unit, and the nozzle 4 is driven to rotate by the connecting pipe 202 and the conversion head 203. The defoamer is more dispersed and has a larger contact area with the foam, thus improving the defoaming efficiency.
[0026] The drive unit includes a motor 204 fixedly connected to the top of the tank 1. A rotating shaft 205 is fixedly connected to the output end of the motor 204. Both the rotating shaft 205 and the rotating tube 201 are fixedly connected to bevel gears 206. The two bevel gears 206 are meshed and connected. The motor 204 is electrically connected to an external power source.
[0027] When in operation, the motor 204 is started, and its output end drives the rotating shaft 205 to rotate. Under the transmission of the bevel gear 206, the rotating tube 201 rotates. The rotating tube 201 drives the connecting tube 202 to rotate. The connecting tube 202 drives the conversion head 203 to rotate. The conversion head 203 drives the nozzle 4 to rotate.
[0028] A metering pump 6 for metering defoamer is fixedly installed on the top of the tank 1. The feed pipe 5 is fixedly installed at the output end of the metering pump 6. A delivery pipe 7 is fixedly connected to the input end of the metering pump 6. The delivery pipe 7 is fixedly connected to the tank 1. The metering pump 6 is electrically connected to an external power source. The metering pump 6 is used to add defoamer in a quantitative manner and can effectively control the amount added. The delivery pipe 7 is connected to an external defoamer container.
[0029] The connecting pipe 202 is slidably connected to the rotating pipe 201. A spline 301 is fixedly connected to the circumferential surface of the rotating pipe 201, and the spline 301 is slidably connected to the connecting pipe 202. A fixed seat 302 is fixedly connected to the rotating pipe 201. A guide rod 303 is fixedly connected to the top of the converter head 203. The guide rod 303 is slidably connected to the fixed seat 302. A limit plate 304 is fixedly connected to the top of the guide rod 303. A limit groove 305 is formed inside the fixed seat 302. The limit plate 304 is slidably connected to the inner wall of the limit groove 305. A spring 30 is fixedly connected between the bottom of the limit plate 304 and the inner wall of the limit groove 305. 6. A connecting rod 307 is fixedly connected to the top of the converter head 203. The end of the connecting rod 307 away from the converter head 203 is set as a hemispherical shape. An arc-shaped protrusion 308 is fixedly connected to the inner wall of the tank body 1. The arc-shaped protrusion 308 is set on the rotation path of the connecting rod 307. The diameter of the limiting plate 304 is larger than the diameter of the guide rod 303, which is used to limit the guide rod 303 and prevent the guide rod 303 from slipping off the fixed seat 302, thereby preventing the converter head 203 and the nozzle 4 from falling off. By setting the spline 301, the rotating tube 201 can drive the connecting tube 202 to rotate, and the connecting tube 202 can slide longitudinally on the spline 301.
[0030] During operation, as the nozzle 4 rotates, the conversion head 203 drives the connecting rod 307 to rotate. When the connecting rod 307 passes the arc-shaped protrusion 308, it is squeezed by the protrusion, causing the connecting rod 307 to drive the connecting pipe 202 to slide down through the conversion head 203. At the same time, the guide rod 303 drives the limiting plate 304 to slide down along the limiting groove 305 and compress the spring 306. After that, the spring 306 returns to its original position, causing the guide rod 303 to drive the conversion head 203 to rise, which in turn causes the nozzle 4 below to shake up and down continuously, making the defoamer more dispersed and further improving the defoaming efficiency.
[0031] The bottom of the converter head 203 is fixedly connected to a stirring rod 8 for stirring lubricating oil. The number of stirring rods 8 is 3 to 8, and the preferred number in this application is 4. In practice, the length can be adjusted as needed, and the maximum length shall not exceed the total length of the tank body 1.
[0032] During operation, as the nozzle 4 rotates, the stirring rod 8 rotates synchronously. At the same time, the stirring rod 8 can shake up and down to stir the defoamer and foam, allowing the defoamer and foam to react more quickly.
[0033] In operation, this defoaming device for lubricating oil production delivers defoamer sequentially from the delivery pipe 7, feed pipe 5, rotating pipe 201, connecting pipe 202, and conversion head 203 to the nozzle 4 via the metering pump 6. Simultaneously, the motor 204 is started, and its output drives the rotating shaft 205 to rotate. Under the transmission of the bevel gear 206, the rotating pipe 201 rotates, and under the transmission of the connecting pipe 202 and conversion head 203, the nozzle 4 rotates, spraying the defoamer onto the foam.
[0034] Meanwhile, as the nozzle 4 rotates, the conversion head 203 drives the connecting rod 307 to rotate. When the connecting rod 307 passes the arc-shaped protrusion 308, it is squeezed by the protrusion, causing the connecting rod 307 to drive the connecting pipe 202 to slide down through the conversion head 203. At the same time, the guide rod 303 drives the limiting plate 304 to slide down along the limiting groove 305 and compress the spring 306. After that, the spring 306 returns to its original position, causing the guide rod 303 to drive the conversion head 203 to rise, which in turn causes the nozzle 4 below it to shake up and down continuously, making the defoamer more dispersed. The stirring rod 8 rotates synchronously and can shake up and down to stir the defoamer and foam, making the defoamer and foam react faster.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
