Description

Technical Field

[0001] The utility model relates to the technical field of lubricating grease production, and specifically relates to a blender for lubricating grease production. Background Technique

[0002] Lubricating grease is a special chemical product used for lubricating mechanical equipment, and it has a wide range of applications in various industries. The production process of lubricating grease mainly includes raw material preparation, mixing and processing, emulsification and dispersion, dehydration and impurity removal, filtration and other links. Its production process is complex and requires strict compliance with specific technological processes and operation methods to ensure the quality and stability of the product.

[0003] The main raw materials of lubricating grease include base oil and additives. The base oil is the main body of lubricating grease, accounting for 60% - 90% of lubricating grease. Additives are added to improve the performance characteristics of lubricating grease. According to different uses and performance requirements, the types and proportions of additives will also change.

[0004] Mixing and processing is the core link in the production of lubricating grease. Its purpose is to fully mix the base oil and additives to form a stable base oil - additive mixture. Mixing and processing first requires adding the base oil and additives to the blending tank in a certain proportion, and then mechanical stirring is carried out until the two are fully mixed. Finally, additives such as antioxidants and preservatives are added for re - mixing.

[0005] Lubricating grease usually appears in the form of an emulsion, and emulsification and dispersion is an essential step in the preparation of lubricating grease.

[0006] Dehydration and impurity removal is the process of removing water in the emulsion through water treatment.

[0007] Filtration is the last link in the production process of lubricating grease, and its main function is to improve the precision and quality of the product.

[0008] After dehydration and impurity removal of lubricating grease, its viscosity increases and fluidity is low. Therefore, the filtration efficiency of lubricating grease after dehydration and impurity removal is relatively low. In order to reduce the working pressure of the filtration process after dehydration and impurity removal of lubricating grease, the existing method is to filter the base oil, additives, antioxidants, preservatives, etc. during the process of adding them to the blending tank during mixing and processing, thereby reducing the impurity content in subsequent processing steps and achieving the purpose of reducing the working pressure of the filtration process.

[0009] In the prior art, a patent document with the application number CN202222415194.4 and the title "A processing and blending device for lubricating grease production" discloses a blending device in which a blending component can move up and down in a tank, facilitating the turning and blending of substances at the bottom. The technical solution of this patent does not disclose a device for filtering the raw materials added to the tank. Therefore, the subsequent filtering process has a high working intensity.

[0010] A patent document with the application number CN202320411747.0 and the title "A processing and blending machine for lubricating grease production" discloses a blending machine capable of filtering lubricating oil and other raw materials. A filter plate is provided between the outer circumference of the shaft rod and the inner circumference of the blending tank above the blending mechanism. The outer circumference of the filter plate is fixedly connected to the inner circumference of the blending tank, and the inner circumference of the filter plate is rotatably connected to the outer circumference of the shaft rod. A cleaning brush is fixedly installed on one side of the outer wall of the shaft rod above the filter plate, and the bottom of the cleaning brush contacts the top of the filter plate. Its function is to improve the filtering efficiency and prevent the filter plate from being blocked. When in use, the lubricating oil and other raw materials enter the blending tank through the feeding port. The filter plate provided in the blending tank filters the lubricating oil and raw materials, and the cleaning brush rotates with the shaft rod to clean the filter plate, thereby improving the filtering efficiency and preventing the filter plate from being blocked. However, in the technical solution disclosed in this patent, it is not convenient to remove the impurities on the filter plate.

[0011] Some base oils are refined from waste oil, and some base oils are refined from plants. When the quality of the base oil is low, the base oil contains various impurities. When taking out the impurities from above the filter plate, the liquid component content in the impurities is relatively large, which is not convenient for subsequent treatment of the impurities intercepted by the filter plate.

Specifically, the sealing plate 17 and the lower end of the housing 2 are sealed and connected through a sealing gasket. A bolt passes through the sealing plate 17 and is threadedly connected with the housing 2.

[0053] An inner block 13 is slidably and sealingly connected in the housing 2 above the sealing plate 17, and a rectangular ring groove 14 is formed on the outer edge of the upper side of the inner block 13. A rectangular ring 15 is slidably and sealingly connected in the ring groove 14, and the rectangular ring 15 is slidably and sealingly connected with the inner wall of the housing 2. Specifically, sealing rings are fixedly and sealingly connected to both the outer edge and the inner edge of the rectangular ring 15.

[0054] A compression spring 16 is arranged in the ring groove 14, one end of the compression spring 16 abuts against the step of the inner block 13, and the other end of the compression spring 16 abuts against the lower end of the rectangular ring 15.

[0055] Multiple slot holes are formed inside the inner block 13, and a filter element 19 is fixed in the slot holes. The upper end of the inner block 13 is flush with the upper end of the filter element 19, and the upper end of the inner block 13 is located inside the rectangular ring 15.

[0056] An inner cover 6 is slidably and sealingly connected in the housing 2 above the inner block 13, the opening of the inner cover 6 faces downward, and multiple through holes 7 are formed in the upper end of the inner cover 6.

[0057] A baffle plate 9 is elastically and slidably connected in the vertical direction inside the inner cover 6, and the baffle plate 9 can block the through hole 7 after moving upward. Specifically, a plurality of optical rods 8 are fixed to the upper end of the baffle plate 9, the optical rods 8 penetrate through the upper end of the inner cover 6, the optical rods 8 are slidably and sealingly connected with the inner cover 6, a baffle 10 is fixed to the upper end of the optical rods 8, and a spring 11 is sleeved on the optical rods 8 between the baffle 10 and the inner cover 6.

[0058] An overflow gap is provided between the baffle plate 9 and the inner cover 6.

[0059] A vertical connecting rod 12 penetrates through the sealing plate 17, the inner block 13 and the baffle plate 9. The upper end of the connecting rod 12 is rotatably connected with the inner cover 6. The connecting rod 12 is threadedly and sealingly connected with the inner block 13 and the sealing plate 17. The connecting rod 12 is slidably and sealingly connected with the baffle plate 9. A hand wheel 18 is concentrically fixed to the lower end of the connecting rod 12.

[0060] After the inner cover 6 presses the rectangular ring 15 downward, it can be hermetically inserted into the rectangular ring 15 cavity between the inner block 13 and the housing 2.

[0061] An inlet pipe 3 is fixedly and sealingly connected to the housing 2 above the inner cover 6.

When the lower end of the inner cover 6 contacts the upper end of the rectangular ring 15, as the inner cover 6 continues to move downward, the inner cover 6 presses the rectangular ring 15 downward, and the compression spring 16 is compressed. During the downward movement of the inner cover 6, the filter residues can be extruded, and the liquid content in the filter residues is reduced, which is convenient for subsequent treatment.

[0064] When it is necessary to remove the filter residues, the outlet pipe 4 and the sealing plate 17 are disassembled, and the inner cover 6, the inner block 13 and the rectangular block are pulled out from the housing 2. At this time, the filter residues are located in the space between the inner cover 6 and the inner block 13, and the filter residues can be prevented from spilling.
