Description

Technical Field

[0001] This utility model relates to the field of cooling vessel technology, and in particular to a cooling vessel for lubricating oil production that is easy to clean. Background Technology

[0002] In the lubricating oil production process, the cooling autoclave is one of the key process equipment, mainly used to cool and solidify or maintain a constant temperature for high-temperature lubricating oil materials. Due to the strong adhesive properties of lubricating oil, residual oil films or coking deposits easily form on the inner wall of the autoclave during cooling. Long-term accumulation not only affects heat transfer efficiency but may also contaminate subsequent batches of products, leading to a decline in product quality. Traditional cooling autoclaves are mostly cleaned by manually entering the autoclave to scrub or by high-pressure water jet rinsing, which suffers from low cleaning efficiency, numerous dead corners, high labor intensity, harsh working environment, and safety hazards. Especially in the confined space, personnel are prone to risks such as suffocation, slipping, or contact with harmful residues, making it difficult to meet the high requirements of automation, safety, and cleanliness in modern chemical production. Therefore, we propose a cooling autoclave for lubricating oil production that is easy to clean. Utility Model Content

[0003] The main objective of this invention is to provide a cooling vessel for lubricating oil production that is easy to clean, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A cooling tank for lubricating oil production that is easy to clean includes a cooling tank body, a feed pipe that communicates with the interior of the cooling tank body is inserted and connected to the outer surface of the cooling tank body, a lifting mechanism is provided on the top of the cooling tank body, and a cleaning mechanism is provided on the top of the cooling tank body that is throttledly connected to the lifting mechanism.

[0006] The cleaning mechanism includes a top cover located on the top of the cooling tank body and connected to the lifting mechanism, a protective cover fixedly installed on the top of the top cover, and a cleaning component that is movably inserted into the top cover and located below the cooling tank body.

[0007] Preferably, the lifting mechanism includes two fixed plates symmetrically connected to the outer surface of the cooling vessel body. A forward and reverse motor is fixedly installed at the lower end of one of the fixed plates, and a guide rod is fixedly connected to the upper end of the other fixed plate. A transmission screw is fixedly connected to the output end of the forward and reverse motor, and the transmission screw is movably connected to the fixed plate through a bearing.

[0008] By adopting the above technical solution: by symmetrically setting fixed plates on both sides of the cooling tank body, installing a transmission screw driven by a positive and negative motor on one side, and setting a guide rod on the other side, a stable lifting guide and transmission system is formed to ensure that the cleaning mechanism lifts and lowers smoothly without swaying.

[0009] Preferably, one side of the top cover is sleeved on the top cover and slidably connected to the top cover, and the other side of the top cover is sleeved on the transmission screw and threadedly connected to the transmission screw. The top cover and the cooling kettle body are coaxially arranged.

[0010] By adopting the above technical solution: one side of the top cover is threadedly connected to the transmission screw, and the other side is slidably engaged with the guide rod, realizing linear lifting motion driven by the screw and guided by the guide rod. The structure is simple and reliable, and the operation is smooth.

[0011] Preferably, the cleaning assembly includes a drive motor and a cleaning body. The drive motor is fixedly installed inside the protective cover, and a drive gear is fixedly connected to the output end of the drive motor. The cleaning body is coaxially inserted and connected to the top cover and is driven by the drive gear.

[0012] By adopting the above technical solution: the drive motor is installed inside the protective cover, and the rotating rod is driven to rotate through the meshing of the drive gear and the transmission gear, so as to achieve stable rotation of the cleaning body, efficient power transmission and good sealing.

[0013] Preferably, the cleaning body includes a rotating rod, which is movably connected to the top cover via a bearing. A transmission gear is fixedly connected to the top of the rotating rod, which is located inside the protective cover and meshes with a drive gear. A high-pressure cleaning pipe is inserted through the middle of the rotating rod, and multiple high-pressure nozzles are connected to the outer surface of the high-pressure cleaning pipe, with each high-pressure nozzle inserted through the rotating rod.

[0014] By adopting the above technical solution, a high-pressure cleaning pipe is installed inside the rotating rod, and multiple high-pressure nozzles are set on the outer periphery, which can spray cleaning liquid onto the vessel wall in all directions during rotation, thereby improving the cleaning coverage and rinsing effect.

[0015] Preferably, the outer surface of the rotating rod is symmetrically connected to two support rods, and a cleaning scraper is fixedly connected between the two support rods on the same side, and the outer surface of the cleaning scraper is in contact with the inner wall of the cooling vessel body.

[0016] By adopting the above technical solution: support rods are symmetrically installed on the outside of the rotating rod and cleaning scrapers are fixedly connected. The scrapers are in contact with the inner wall of the vessel and scrape away stubborn dirt simultaneously during the rotation and lifting process, so as to achieve the coordinated cleaning of mechanical scraping and high-pressure rinsing.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up an automated cleaning mechanism driven by a lifting mechanism, comprehensive and efficient cleaning of the interior of the cooling vessel is achieved. The high-pressure nozzles in the cleaning mechanism continuously spray cleaning fluid during the lifting process with the rotating rod. Combined with the cleaning scraper that is close to the vessel wall for mechanical scraping, a composite cleaning mode of "high-pressure flushing + dynamic scraping" is formed, which can effectively remove stubborn oil stains and carbon deposits attached to the inner wall, significantly improve cleaning quality and efficiency, and avoid the dead corners and incomplete cleaning problems of traditional manual cleaning.

[0019] 2. The entire cleaning process does not require personnel to enter the vessel. The top cover and cleaning components are automatically raised and lowered by a forward and reverse motor-driven transmission screw. The entire cleaning process can be completed with the help of external control, which greatly reduces the labor intensity and safety risks of operators. At the same time, the cleaning mechanism is integrated into the detachable top cover, which is compact in structure, easy to maintain, and does not affect the normal sealing and production operation of the cooling vessel. It achieves efficient connection between production and cleaning, and has good practicality and promotion value. Attached Figure Description

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A cooling vessel for lubricating oil production that is easy to clean includes a cooling vessel body 1, a feed pipe 2 that communicates with the interior of the cooling vessel body 1 is inserted and connected to the outer surface of the cooling vessel body 1, a lifting mechanism 3 is provided on the top of the cooling vessel body 1, and a cleaning mechanism 4 is provided on the top of the cooling vessel body 1 that is drivenly connected to the lifting mechanism 3.

[0030] In this embodiment, the cleaning mechanism 4 includes a top cover 41 located on the top of the cooling vessel body 1 and connected to the lifting mechanism 3, a protective cover 42 fixedly installed on the top of the top cover 41, and a cleaning component 43 movably inserted into the top cover 41 and located in the cooling vessel body 1 at its lower part. The lifting mechanism 3 includes two fixed plates 31 symmetrically connected to the outer surface of the cooling vessel body 1. A forward and reverse motor 32 is fixedly installed at the lower end of one fixed plate 31, and a guide rod 34 is fixedly connected at the upper end of the other fixed plate 31. A transmission screw 33 is fixedly connected to the output end of the forward and reverse motor 32, and the transmission screw 33 is movably connected to the fixed plate 31 through a bearing. One side of the top cover 41 is sleeved on the top cover 41 and slidably connected to the top cover 41. The other side of the top cover 41 is sleeved on the transmission screw 33 and threadedly connected to the transmission screw 33. The top cover 41 is coaxially arranged with the cooling vessel body 1.

[0031] Through the above scheme: the forward and reverse motor 32 drives the transmission screw 33 to start rotating in the forward direction. Since one side of the top cover 41 is threaded onto the transmission screw 33 and the other side is threaded onto the guide rod 34 to achieve sliding guidance, under the rotation of the transmission screw 33, the top cover 41 moves smoothly downward in the vertical direction under the threaded transmission of the screw and the guiding constraint of the guide rod 34. As the top cover 41 descends, the drive motor 431 fixed on the top cover 41 and the cleaning body 433 connected to it descend synchronously to perform cleaning. After cleaning is completed, the forward and reverse motor 32 reverses, the transmission screw 33 rotates in the reverse direction, and drives the top cover 41 to rise smoothly along the guide rod 34 to the original high position, and the cleaning mechanism 4 is reset as a whole.

[0032] In this embodiment, the cleaning component 43 includes a drive motor 431 and a cleaning body 433. The drive motor 431 is fixedly installed inside the protective cover 42, and a drive gear 432 is fixedly connected to the output end of the drive motor 431. The cleaning body 433 is coaxially inserted and connected to the top cover 41 and is driven by the drive gear 432. The cleaning body 433 includes a rotating rod 434, which is movably inserted and connected to the top cover 41 through a bearing. A transmission gear 435 is fixedly connected to the top of the rotating rod 434. Located inside the protective cover 42 and meshing with the drive gear 432, the middle of the rotating rod 434 is connected to a high-pressure cleaning pipe 436. The outer surface of the high-pressure cleaning pipe 436 is connected to multiple high-pressure nozzles 437, and all the high-pressure nozzles 437 are connected to the rotating rod 434. Two support rods 438 are symmetrically connected to the outer surface of the rotating rod 434. A cleaning scraper 439 is fixedly connected between the two support rods 438 on the same side, and the outer surface of the cleaning scraper 439 is in contact with the inner wall of the cooling vessel body 1.

[0033] Through the above scheme: Simultaneously or slightly after the top cover 41 descends, the drive motor 431 starts, and its output drive gear 432 drives the transmission gear 435 to rotate, thereby driving the rotating rod 434 to rotate around its central axis. Since the rotating rod 434 is movably connected to the top cover 41 through bearings, it can achieve independent rotational movement. When the rotating rod 434 rotates, the high-pressure nozzle 437 on it rotates synchronously with the rotating rod, spraying the high-pressure cleaning fluid in a fan shape or at multiple angles onto the inner wall of the cooling vessel body 1, achieving all-round, no-dead-angle cleaning. Simultaneously, the cleaning scraper connected to the two support rods 438... The plate 439 rotates with the rotating rod 434 and slides close to the inner wall of the cooling vessel body 1. The edge of the cleaning scraper 439 is used to mechanically scrape off the oil, coking matter or residues attached to the inner wall, realizing a dual cleaning mode of "high pressure flushing + mechanical scraping". Under the continuous drive of the forward and reverse motors 32, the top cover 41 drives the entire cleaning mechanism 4 to slowly descend from the top to the bottom of the cooling vessel body 1. During this process, the rotating high pressure nozzle 437 and the moving cleaning scraper 439 continuously clean the inner wall of the cooling vessel from top to bottom, ensuring that the entire inner wall surface is effectively cleaned.

[0034] It should be noted that this utility model is a cooling kettle for lubricating oil production that is easy to clean. When it is necessary to clean the inner wall of the cooling kettle body 1, the control system starts the forward and reverse motor 32. The forward and reverse motor 32 drives the transmission screw 33 to start rotating in the forward direction. Since one side of the top cover 41 is threaded onto the transmission screw 33 and the other side is threaded onto the guide rod 34 to achieve sliding guidance, under the rotation of the transmission screw 33, the top cover 41 moves smoothly downward in the vertical direction under the threaded transmission of the screw and the guiding constraint of the guide rod 34. As the top cover 41 descends, the top cover 41 is fixed to the bottom. The drive motor 431 and the cleaning body 433 connected to it descend synchronously. At this time, the high-pressure cleaning pipe 436 is connected to an external high-pressure water source or cleaning liquid source through a flexible hose to continuously supply liquid. At the same time or slightly after the top cover 41 descends, the drive motor 431 starts, and the drive gear 432 at its output end drives the transmission gear 435 to rotate, thereby driving the rotating rod 434 to rotate around its central axis. Since the rotating rod 434 is movably connected to the top cover 41 through a bearing, it can achieve independent rotational movement. When the rotating rod 434 rotates, the high-pressure nozzle 437 on it rotates synchronously with the rotating rod, applying high-pressure cleaning. The liquid is sprayed in a fan shape or at multiple angles onto the inner wall of the cooling vessel body 1, achieving all-round, thorough cleaning. Simultaneously, the cleaning scraper 439 connected to the two support rods 438 rotates with the rotating rod 434 and slides close to the inner wall of the cooling vessel body 1. The edges of the cleaning scraper 439 mechanically scrape away oil, coke, or residue adhering to the inner wall, achieving a dual cleaning mode of "high-pressure rinsing + mechanical scraping." Under the continuous drive of the forward and reverse motors 32, the top cover 41 drives the entire cleaning mechanism 4 to slowly descend from the top to the bottom of the cooling vessel body 1. During this process, the rotating high-pressure nozzle 437 and the moving... The moving cleaning scraper 439 continuously cleans the inner wall of the cooling vessel from top to bottom, ensuring that the entire inner wall surface is effectively cleaned. After cleaning, the forward and reverse motors 32 reverse, and the transmission screw 33 rotates in the opposite direction, driving the top cover 41 to rise smoothly along the guide rod 34 back to its original high position, and the cleaning mechanism 4 is reset as a whole. At this time, the discharge port at the bottom of the cooling vessel (not shown in the figure) can be opened to discharge the cleaning waste liquid. The entire cleaning process can be set by the PLC control system to set parameters such as lifting speed, rotation speed, cleaning time, and start-stop sequence of the forward and reverse motors, so as to realize a fully automatic or semi-automatic cleaning process and reduce manual intervention.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
