[0002] A vertical mixer is a mechanical device used to mix different materials, typically employing a vertical structure. Its main function is to mix two or more materials uniformly to achieve specific process requirements. There are many types and specifications of vertical mixers, commonly including single-shaft mixers, twin-shaft mixers, and planetary mixers. The advantages of vertical mixers include high mixing efficiency, good mixing uniformity, and small footprint, making them suitable for industries such as chemical, pharmaceutical, food, and feed processing.

[0003] During the operation of a vertical high-power mixer, the rotor bearing housing structure is a key component to ensure stable rotor rotation, and its performance directly affects the mixer's working efficiency and service life.

[0004] The existing bearing package has poor bearing lubrication, resulting in an imbalance of forces on the overall bearing, which in turn leads to a short service life of the equipment. Utility Model Content

Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1-2 , Figure 1 This is a structural diagram of the rotor bearing housing structure of a vertical high-power mixer according to this utility model. Figure 2 This is a schematic diagram of the rotor bearing housing structure of a vertical high-power mixer according to this utility model.

[0019] This utility model provides a rotor bearing housing structure for a vertical high-power mixer, comprising a housing 101 and a lubrication assembly 102. The lubrication assembly 102 includes an upper end cover 103, a lower end cover 104, a rotating shaft 105, a lower end bearing 106, a middle end bearing 107, an upper end bearing 108, an oil baffle groove 109, an oil pipe component 110, a lubricating oil pipe 111, an oil inlet pipe 112, a shaft body 113, a limiting groove 114, a mounting hole 115, a limiting plate 116, and a round nut 117. This solution solves the problem of poor bearing lubrication in existing bearing housings, leading to unbalanced bearing forces and consequently short equipment lifespan.

[0020] In this embodiment, the upper end cover 103 is detachably connected to the housing 101 and is located at the top of the housing 101; the lower end cover 104 is detachably connected to the housing 101 and is located at the bottom of the housing 101; the rotating shaft 105 is slidably connected to the housing 101 and is located inside the housing 101; the lower end bearing 106 is connected to the housing 101 and is located outside the rotating shaft 105; the middle end bearing 107 is connected to the housing 101 and is located above the lower end bearing 106; the upper end bearing 108 is connected to the housing 101 and is located at the bottom of the upper end cover 103; and the oil baffle groove 109 is connected to the housing 101 and is located at the middle end bearing 108. On the outside of bearing 07, the housing 101 protects the internal structure of the equipment. A bearing housing is formed by three bearings: the lower bearing 106, the middle bearing 107, and the upper bearing 108. The upper bearing 108 and the lower bearing 106 bear the inertial torque of the rotating shaft 105, while the middle bearing 107 bears the weight of the rotating shaft 105, thereby improving balance and stability. The oil pipe component 110 delivers lubricating oil to the lower bearing 106. The middle bearing 107 is self-lubricated by the oil baffle groove 109, and the upper bearing 108 is externally lubricated. This solves the problem of poor lubrication effect of existing bearing housings, which leads to unbalanced bearing forces and short service life of the equipment.

[0021] The oil pipe component 110 includes a lubricating oil pipe 111 and an oil inlet pipe 112. The oil inlet pipe 112 is fixedly connected to the housing 101 and located on one side of the housing 101. The lubricating oil pipe 111 is connected to the oil inlet pipe 112 and to the housing 101, and is located on the inner side of the housing 101. The oil inlet pipe 112 is used to determine the oil inlet position of the lubricating oil pipe 111 on the housing 101. Oil is injected into the lubricating oil pipe 111 through the oil inlet pipe 112. The lubricating oil pipe 111 injects lubricating oil into the outer side of the lower bearing 106 to provide lubrication for the lower bearing 106.

[0022] Secondly, the rotating shaft 105 includes a shaft body 113 and a limiting groove 114. The shaft body 113 is slidably connected to the housing 101 and is located inside the housing 101. The limiting groove 114 is provided on the shaft body 113. The shaft body 113 serves as the main body of the rotor shaft. The limiting groove 114 on the shaft body 113 is used to limit the position when the shaft body 113 is connected to the device to be driven, so as to ensure the stability between the shaft body 113 and the device to be driven.

[0023] Furthermore, the lubrication assembly 102 also includes a mounting hole 115 and a limiting plate 116. The limiting plate 116 is fixedly connected to the shaft 113 and is located on one side of the shaft 113. The mounting hole 115 is provided on one side of the housing 101. The mounting hole 115 is used for the installation and connection of the device. The limiting plate 116 is used to limit the position between the end of the shaft 113 and the housing 101.

[0024] Finally, the lubrication assembly 102 also includes a round nut 117, which is connected to the intermediate bearing 107 and located on one side of the intermediate bearing 107. The round nut 117 is used to change the bearing clearance. By tightening or loosening the round nut 117, the clamping force between the inner ring of the intermediate bearing 107 and the shaft shoulder is changed, thereby adjusting the clearance between the rolling elements and the raceway inside the intermediate bearing 107.

[0025] In the rotor bearing housing structure of a vertical high-power mixer using this utility model, the housing 101 is used to ensure the internal structure of the equipment. A bearing housing is formed by three bearings: a lower bearing 106, a middle bearing 107, and an upper bearing 108. The upper bearing 108 and the lower bearing 106 bear the inertial torque of the rotating shaft 105, while the middle bearing 107 bears the weight of the rotating shaft 105, thereby improving balance and stability. The oil pipe component 110 is used to supply lubricating oil to the lower bearing 106, the middle bearing 107 is self-lubricated using the oil baffle groove 109, and the upper bearing 108 is externally lubricated. This solves the problem of poor lubrication in existing bearing housings, which leads to unbalanced bearing forces and consequently short equipment lifespan.

[0026] The above-disclosed embodiments are merely preferred embodiments of the rotor bearing housing structure of a vertical high-power mixer according to the present invention. Of course, they should not be construed as limiting the scope of the present invention. Those skilled in the art can understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention still fall within the scope of the present invention.
