Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil production equipment, in particular to a weighing device for producing high and low temperature resistant grease additives. Background Technique

[0002] Currently, during the production of lubricating oil, due to the different specific gravities of the required raw materials, the raw materials need to be separately transported to the weighing device through raw material barrels. After the raw materials are accurately weighed on the weighing device, they are then transported into the mixer for mixing treatment.

[0003] In the existing lubricating oil production weighing device, since the lubricating oil raw materials often have a high viscosity, the lubricating oil raw materials after measurement are likely to remain on the inner wall of the weighing barrel, resulting in raw material loss, violating the principle of clean production. At the same time, the raw material ratio is unbalanced, affecting the quality of the produced lubricating oil raw materials.

[0004] The existing Chinese patent with the publication number CN212903500U discloses a raw material weighing device for lubricating oil production, which includes a weighing sensor, a base, a weighing barrel, a feed pipe, and a discharge pipe. The weighing sensor is horizontally arranged, the bottom end of the weighing sensor is fixedly connected to one end of the base away from the ground, the bottom end of the weighing barrel abuts against the weighing end of the weighing sensor, the weighing barrel is arranged in a rectangular closed structure, the feed pipe is fixedly connected to the outer top surface of the weighing barrel, the discharge pipe is fixedly connected to the outer bottom wall of the weighing barrel, both the feed pipe and the discharge pipe are communicated with the weighing barrel, a feed valve is arranged on the feed pipe, a discharge valve is arranged on the discharge pipe, the weighing barrel includes an inner barrel and an outer barrel, the outer side wall of the inner barrel and the inner side wall of the outer barrel are far away from each other, one end of the inner barrel away from the weighing sensor is fixedly connected with a vibration assembly for vibrating the weighing barrel, and a lifting assembly for lifting the weighing barrel is arranged on the base.

[0005] In view of the above and related existing technologies, the inventor believes that there are often the following defects: after weighing, the raw materials still need to be input into the mixing device for mixing, which increases the operation steps and processes, and the production efficiency is not high, and improvement is needed; therefore, a weighing device for producing high and low temperature resistant grease additives is proposed for the above problems. Content of the Utility Model

[0006] In order to make up for the deficiencies of the existing technology and solve the above-mentioned technical problems, the utility model proposes a weighing device for producing high and low temperature resistant grease additives.

[0007] The technical solution adopted by the present utility model to solve its technical problems is as follows: A weighing device for the production of high and low temperature resistant grease additives according to the present utility model includes an outer cylinder and an inner cylinder.
