Description

Technical Field

[0001] This utility model belongs to the technical field of conveying devices, and in particular relates to a conveying device for lubricating oil production. Background Technology

[0002] With the acceleration of industrial modernization, the demand for lubricating oil in various fields continues to rise, prompting the continuous expansion of lubricating oil production scale. At the same time, the market's requirements for lubricating oil quality are becoming increasingly stringent. It is necessary not only to meet basic lubrication performance, but also to have good anti-oxidation and anti-wear properties. This means that the production process needs to be more refined and efficient. From raw material procurement and processing to finished product output, every link faces the challenge of improving production efficiency and product quality stability. In this context, as a key link connecting different production processes, the performance of conveying devices directly affects the operating efficiency and cost control of the entire production line.

[0003] However, during the use of existing lubricating oil production conveying devices, a large amount of impurities and oil stains will accumulate on the surface of the filter plates over time. These impurities will gradually accumulate, block the filter holes, reduce the filtration accuracy, and affect the quality and performance of the oil. Summary of the Invention

[0004] The purpose of this utility model is to provide a conveying device for lubricating oil production. By setting up a cleaning mechanism, it solves the problem that in the existing conveying devices for lubricating oil production, a large amount of impurities and oil stains will accumulate on the surface of the filter plate over time. These impurities will gradually accumulate, block the filter holes, reduce the filtration accuracy, and affect the quality and performance of the oil.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a conveying device for lubricating oil production, including a conveying pipe, on which a cleaning mechanism and a check mechanism are provided;

[0007] The right side of the delivery pipe is connected to the centrifugal pump. The cleaning mechanism includes a filter plate fixedly connected to the inner wall of the delivery pipe. A cross support frame 1 is fixedly connected to the inner wall of the delivery pipe. The check mechanism includes a cross support frame 2 fixedly connected to the inner wall of the delivery pipe. A protective shell is fixedly connected to the right side of the cross support frame 1. A motor is fixedly connected to the inner wall of the protective shell.

[0008] Furthermore, the output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The left side of the rotating shaft extends outside the protective shell and passes through a cross support frame. The rotating shaft is rotatably connected to the cross support frame. Several L-shaped connecting rods are fixedly connected to the outer wall of the rotating shaft. Scrapers are fixedly connected to the left side of each of the L-shaped connecting rods. The left side of each of the scrapers is in contact with the filter plate. Several stirring blades are fixedly connected to the outer wall of the rotating shaft.

[0009] Furthermore, a rotating groove is provided inside the cross support frame, a retaining ring is fixedly connected to the outer wall of the rotating shaft, the outer wall of the retaining ring extends into the rotating groove, the retaining ring is rotatably connected to the rotating groove, a circular ring is fixedly connected to the inner wall of the conveying pipe, and a piston is slidably connected to the inner wall of the circular ring.

[0010] Furthermore, a telescopic rod is fixedly connected to the left side of the piston, and the left side of the telescopic rod is fixedly connected to the second cross support frame. A spring is sleeved on the outer wall of the telescopic rod, and the left side of the spring is fixedly connected to the second cross support frame, while the right side of the spring is fixedly connected to the piston.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a cleaning mechanism, during the transportation of lubricating oil, the motor inside the protective shell is started, which drives the rotating shaft to rotate. During this process, the rotating groove and the retaining ring will cooperate to ensure the stable rotation of the rotating shaft. The rotating shaft will drive the stirring plate to rotate, breaking up larger lumps in the conveyed lubricating oil and filtering it through the filter plate. When the rotating shaft rotates, it will also drive the scraper to rotate through the L-shaped connecting rod to clean the filter plate, so that the lubricating oil can be filtered, intercepting impurities, particles and larger substances that may remain after breaking up lumps, reducing the product quality decline caused by impurities, preventing filter plate clogging, keeping the filter plate unobstructed, ensuring the smooth passage of lubricating oil, and maintaining the stable operation of the conveying device.

[0013] 2. By setting a check valve mechanism, during delivery, the lubricating oil on the right side is driven by the centrifugal pump to push against the piston, causing it to move to the left. This compresses the telescopic rod and spring. When the spring is compressed, it undergoes elastic deformation and generates elastic force. At this time, a gap is formed between the piston and the ring, through which the lubricating oil flows to the desired delivery position. When the centrifugal pump stops working, the lubricating oil loses its driving force, and the piston is reset by the elastic force of the spring, preventing backflow of lubricating oil. This ensures that the lubricating oil flows in the predetermined direction, avoiding a series of problems caused by backflow, such as contaminating the processed lubricating oil and affecting subsequent production processes. By avoiding backflow, the service life of the centrifugal pump and related equipment is extended, and the cost of equipment maintenance and replacement is reduced.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0024] Please see Figure 1-5 As shown, this utility model is a conveying device for lubricating oil production, including a conveying pipe 1, a cleaning mechanism 2 and a check mechanism 3 provided on the conveying pipe 1, and the right side of the conveying pipe 1 is connected to a centrifugal pump.

[0025] The cleaning mechanism 2 includes a filter plate 211 fixedly connected to the inner wall of the conveying pipe 1. A cross support frame 212 is fixedly connected to the inner wall of the conveying pipe 1. A protective shell 213 is fixedly connected to the right side of the cross support frame 212. A motor 214 is fixedly connected to the inner wall of the protective shell 213. The output shaft of the motor 214 is fixedly connected to a rotating shaft 215 via a coupling. The left side of the rotating shaft 215 extends outside the protective shell 213 and passes through the cross support frame 212. The rotating shaft 215 is rotatably connected to the cross support frame 212. Several L-shaped connecting rods 216 are fixedly connected to the outer wall of the rotating shaft 215. Scrapers 217 are fixedly connected to the left side of each of the L-shaped connecting rods 216. The left side of the scraper 217 is in contact with the filter plate 211. Several stirring blades 218 are fixedly connected to the outer wall of the rotating shaft 215. A rotating groove 219 is opened in the cross support frame 212. A retaining ring 220 is fixedly connected to the outer wall of the rotating shaft 215. The outer wall of the retaining ring 220 extends into the rotating groove 219. The retaining ring 220 is rotatably connected to the rotating groove 219. By setting the cleaning mechanism 2, the lubricating oil can be filtered to intercept impurities, particles and larger substances that may remain after breaking up agglomerates. This reduces the decline in product quality caused by impurities and prevents the filter plate 211 from clogging. It can keep the filter plate 211 unobstructed, ensure the smooth passage of lubricating oil, and maintain the stable operation of the conveying device.

[0026] The check mechanism 3 includes a cross support frame 311 fixedly connected to the inner wall of the conveying pipe 1. A ring 312 is fixedly connected to the inner wall of the conveying pipe 1. A piston 313 is slidably connected to the inner wall of the ring 312. A telescopic rod 314 is fixedly connected to the left side of the piston 313. The left side of the telescopic rod 314 is fixedly connected to the cross support frame 311. A spring 315 is sleeved on the outer wall of the telescopic rod 314. The left side of the spring 315 is fixedly connected to the cross support frame 311, and the right side of the spring 315 is fixedly connected to the piston 313. By setting the check mechanism 3, the lubricating oil can be ensured to flow in a predetermined direction, avoiding a series of problems caused by backflow, such as contaminating the processed lubricating oil and affecting subsequent production processes. By avoiding backflow, the service life of centrifugal pumps and other related equipment is extended, and the cost of equipment maintenance and replacement is reduced.

[0027] A specific application of this embodiment is as follows: In use, first connect the right side of the delivery pipe 1 to the centrifugal pump, insert the left side of the delivery pipe 1 into the container to be transported, and then start the centrifugal pump to transport the lubricating oil from the right side of the delivery pipe 1 to the left side until it flows into the container. During the transportation of the lubricating oil, start the motor 214 inside the protective shell 213 to drive the rotating shaft 215 to rotate. During this process, the rotating groove 219 and the retaining ring 220 will cooperate to ensure the stable rotation of the rotating shaft 215. The rotating shaft 215 will drive the stirring plate 218 to rotate, breaking up larger lumps in the transported lubricating oil and filtering it through the filter plate 211. When shaft 215 rotates, shaft 215 also drives scraper 217 to rotate through L-shaped connecting rod 216 to clean filter plate 211. During conveying, the lubricating oil on the right side will push piston 313 under the drive of centrifugal pump, causing it to move to the left, thereby compressing telescopic rod 314 and spring 315. When spring 315 is compressed, it will undergo elastic deformation and generate elastic force. At this time, piston 313 will directly create a gap with ring 312, and lubricating oil will flow through this gap to the required conveying position. When centrifugal pump stops working, lubricating oil loses driving force, and piston 313 will be reset under the action of spring 315, avoiding backflow of lubricating oil.
