Description

Technical Field

[0001] This utility model relates to the technical field of lubricating oil processing equipment, specifically a lubricating oil blending device. Background Technology

[0002] Lubricating oil is a complex mixture of hydrocarbons, mainly composed of base oil and additives. During the production process, the base oil and additives need to be thoroughly stirred and blended to ensure the stability of the lubricating oil's performance. Currently, existing lubricating oil blending equipment usually uses a stirring structure to mix the base oil and additives. However, it is not convenient to scrape off the lubricating oil on the inner wall of the blending equipment during stirring and blending. Some base oil or additives tend to adhere to the inner wall of the blending tank and cannot participate in sufficient stirring, resulting in uneven composition of the blended lubricating oil and affecting its performance stability.

[0003] As disclosed in the prior art, Chinese utility model publication CN222956234U discloses a lubricating oil blending device. This utility model includes a blending tank, a feeding mechanism, and a stirring mechanism. A feeding pipe is installed at the top of the blending tank, and multiple support frames are installed at the bottom of the blending tank. The feeding mechanism includes a stirring cylinder, and a connecting pipe is installed at the top of the stirring cylinder. In the above structure, there is no structure for scraping the inner wall of the blending tank. In actual use, the lubricating oil adhering to the inner wall of the blending tank cannot be effectively stirred, resulting in poor blending effect and affecting product quality. That is, the problem mentioned above exists: lubricating oil easily adheres to the inner wall of the blending tank and cannot participate in sufficient stirring. Therefore, we need to propose a lubricating oil blending device. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A lubricating oil blending device includes: a blending tank 1; a blending mechanism 2 for stirring and blending the lubricating oil, wherein the blending mechanism 2 is disposed inside the blending tank 1; and a scraping mechanism 3 for timely scraping off the lubricating oil from the inner wall of the blending tank 1, wherein the blending mechanism 2 is disposed on the scraping mechanism 3, and the scraping mechanism 3 is disposed inside the blending tank 1.

[0025] By coordinating the mixing tank 1, the mixing mechanism 2, and the scraping mechanism 3, the mixing mechanism 2 can stir and mix the base oil and additives in the tank, while the scraping mechanism 3 can promptly remove the lubricating oil adhering to the inner wall of the mixing tank 1. This solves the problems of raw material waste and uneven composition caused by residue on the inner wall of traditional mixing devices, thereby improving the uniformity of lubricating oil mixing and the stability of product performance.

[0026] Specifically, the scraping mechanism 3 includes a motor 31, a rotating rod 32, a first scraper 33, multiple sets of second scrapers 34, and multiple sets of third scrapers 35. The motor 31 is fixedly installed on the top of the mixing tank 1, and the output end of the motor 31 is fixedly connected to the top of the rotating rod 32 through a coupling. The rotating rod 32 is rotatably installed on the inner top of the mixing tank 1. The first scraper 33 is fixedly installed on the outer side of the rotating rod 32. The tops of the multiple sets of second scrapers 34 are all fixedly connected to the bottoms of the first scraper 33, and the bottoms of the multiple sets of second scrapers 34 are respectively fixedly connected to the tops of the multiple sets of third scrapers 35.

[0027] With the configuration of motor 31, rotating rod 32, first scraper 33, multiple sets of second scrapers 34 and multiple sets of third scrapers 35, motor 31 can be a Y-series three-phase asynchronous motor. Motor 31 drives rotating rod 32 to rotate through coupling, driving first scraper 33, second scraper 34 and third scraper 35 to run synchronously, realizing automated scraping of different areas of the inner wall of blending tank 1 without manual intervention, reducing the operating burden. The combination structure of multiple sets of scrapers covers more areas inside blending tank 1, improving the comprehensiveness of scraping and avoiding local residue accumulation.

[0028] The first scraper 33 is arranged in a cross shape, and the top of the first scraper 33 is in contact with the inner top of the mixing tank 1. The outer walls of the multiple sets of second scrapers 34 are in contact with the inner wall of the mixing tank 1.

[0029] By setting the first scraper 33 and the second scraper 34, the cross-shaped first scraper 33 increases the contact area with the top of the mixing tank 1. When the first scraper 33 rotates, it can efficiently remove the raw materials attached to the top of the mixing tank 1 and improve the scraping effect. Meanwhile, the multiple sets of second scrapers 34 can scrape off the side wall residue during synchronous rotation, further reducing raw material waste and ensuring the accuracy of the blending ingredients.

[0030] Specifically, the bottom of the mixing tank 1 is arc-shaped, and the outer walls of multiple sets of third scrapers 35 are all in contact with the inner bottom of the mixing tank 1.

[0031] By setting up the mixing tank 1 and the third scraper 35, the arc-shaped structure at the bottom of the mixing tank 1 facilitates the subsequent discharge of lubricating oil, reduces discharge residue, improves discharge efficiency, and avoids the problem of material accumulation caused by a flat bottom. The third scraper 35 is also arc-shaped, which can accurately remove residual materials at the arc-shaped bottom, avoid cleaning blind spots caused by the special shape of the bottom, ensure that the raw materials in the tank fully participate in the mixing, and improve the consistency of raw material utilization and mixing effect.

[0032] Among them, a fixing ring 4 is fixedly installed on the outer side of the rotating rod 32, and multiple sets of support rods 5 are fixedly installed on the outer side of the fixing ring 4. The ends of the multiple sets of support rods 5 away from the fixing ring 4 are respectively fixedly connected to the inner walls of multiple sets of third scrapers 35.

[0033] The installation of the fixing ring 4 and the support rod 5 enhances the connection stability between the third scraper 35 and the rotating rod 32, preventing the scraper from shaking or deforming when rotating at high speed or contacting hard residues, ensuring the reliability of the scraping process and the service life of the scraper, and ensuring long-term stable operation.

[0034] In a further preferred embodiment, the mixing mechanism 2 includes a connecting seat 21, multiple sets of L-shaped connecting rods 22 and multiple sets of stirring rods 23; the connecting seat 21 is fixedly installed on the outside of the rotating rod 32, the multiple sets of L-shaped connecting rods 22 are all fixedly installed on the outside of the connecting seat 21, and multiple sets of stirring rods 23 are respectively fixedly installed on the outside of the multiple sets of L-shaped connecting rods 22.

[0035] With the connection seat 21, multiple sets of L-shaped connecting rods 22 and multiple sets of stirring rods 23, when the rotating rod 32 rotates, it can drive the connection seat 21 and the multiple sets of L-shaped connecting rods 22 and stirring rods 23 above it to rotate synchronously. The multiple sets of L-shaped connecting rods 22 and multiple sets of stirring rods 23 can stir materials at different depths and in different areas in the mixing tank 1, expand the mixing range, enhance the mixing strength of base oil and additives, and improve the blending efficiency and uniformity.

[0036] Specifically, a fixing block 6 is fixedly installed at the bottom of the rotating rod 32, and multiple sets of first fixing rods 7 are fixedly installed on the outside of the fixing block 6. A second fixing rod 8 is fixedly installed at the end of the multiple sets of first fixing rods 7 away from the fixing block 6, and the multiple sets of second fixing rods 8 are all inclined.

[0037] With the setting of fixed block 6, first fixed rod 7 and second fixed rod 8, when rotating rod 32 rotates, it can drive fixed block 6, first fixed rod 7 and second fixed rod 8 to rotate synchronously, thereby forming an additional stirring and mixing effect on the material at the bottom of mixing tank 1. The inclined structure of second fixed rod 8 can further enhance the stirring effect and ensure that the material at the bottom of mixing tank 1 is fully mixed.

[0038] The top of the mixing tank 1 is connected to the feed pipe 9, and the bottom of the mixing tank 1 is connected to the discharge pipe 10.

[0039] With the inlet pipe 9 and outlet pipe 10, the inlet pipe 9 provides a convenient channel for the input of base oil and additives, and can directly and accurately introduce raw materials into the blending tank 1. The top of the inlet pipe 9 is equipped with a sealing cap, which can be closed after the base oil and additives are injected, effectively preventing external dust, impurities and other contaminants from entering the tank, ensuring a clean environment during the blending process, and reducing the impact of contaminants on the quality of lubricating oil. The outlet pipe 10 at the bottom provides a smooth discharge path for the blended lubricating oil, making it easy to quickly export the blended product.

[0040] Working principle: When using this utility model, firstly, the base oil and additives are injected through the feed pipe 9 at the top of the mixing tank 1, and then the motor 31 is started. The output end of the motor 31 drives the rotating rod 32 to rotate through the coupling.

[0041] When the rotating rod 32 rotates, on the one hand, the rotation of the rotating rod 32 drives the blending mechanism 2 to work: the connecting seat 21 rotates with the rotating rod 32, which in turn drives multiple sets of L-shaped connecting rods 22 and multiple sets of stirring rods 23 to rotate, stirring and blending the base oil and additives in the blending tank 1. The fixing block 6 at the bottom of the rotating rod 32 rotates with the rotating rod 32, which drives multiple sets of first fixing rods 7 and multiple sets of second fixing rods 8 that are set at an inclination to rotate, further enhancing the stirring effect and making the base oil and additives fully mixed.

[0042] On the other hand, the scraping mechanism 3 is driven to operate: the cross-shaped first scraper 33 rotates with the rotating rod 32 to scrape the inner top of the mixing tank 1 to prevent the base oil and additives from adhering. Multiple sets of second scrapers 34 connected to the bottom of the first scraper 33 rotate synchronously. Since the outer wall of the second scraper 34 is in contact with the inner wall of the mixing tank 1, the inner side wall of the mixing tank 1 can be completely scraped. At the same time, multiple sets of third scrapers 35 rotate under the drive of the rotating rod 32. Since the bottom of the mixing tank 1 is arc-shaped and the outer wall of the third scraper 35 is in contact with the inner bottom of the mixing tank 1, the inner bottom of the mixing tank 1 is scraped. The fixing ring 4 and multiple sets of support rods 5 play a role in strengthening and fixing the third scraper 35 to ensure that the scraping process is stable and reliable.

[0043] After mixing, the mixed lubricating oil is discharged through the discharge pipe 10 at the bottom of the mixing tank 1.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
