AI Technical Summary
Traditional vertical rotary drum machines are prone to shaking during drum rotation and insufficient material friction, resulting in low cleaning or mixing efficiency.
Corrugated ridges are set on the inner wall of the cylinder, and tracks are set on the inner wall of the outer shell to cooperate with the balls. The balls roll on the tracks to keep the cylinder stable, and the corrugated ridges increase the friction of material tumbling.
This achieves stability of the cylinder during rotation, increases the friction of material tumbling, and thus improves cleaning efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of drum machines, and in particular to a high-efficiency and stable vertical drum machine. Background Technology
[0002] Rotary drum machines are widely used in mining, construction, chemical, and food industries. They are mainly used for screening, washing, and mixing processes. A rotary drum machine mainly consists of a drum body and a motor that drives the drum to rotate. Currently, most rotary drum machines are horizontal, meaning the drum body is driven by a motor. This design results in a larger space requirement and also tends to cause a larger tumbling amplitude and lower tumbling frequency of the material inside the drum, leading to insufficient material friction and difficulty in efficiently cleaning or mixing the material. This led to the development of vertical rotary drum machines. However, traditional vertical rotary drum machines are prone to lateral shaking during rotation, especially noticeable at the start and end of rotation. Furthermore, the overly smooth inner wall of the drum in traditional vertical rotary drum machines results in insufficient friction during material tumbling, hindering efficient cleaning or mixing. Therefore, improvements are still needed. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a high-efficiency and stable vertical rotary drum machine, comprising an outer shell and a cylindrical body. The cylindrical body is installed inside the outer shell, and a pulsator is provided at the bottom of the cylindrical body. A rotating shaft is provided at the lower end of the pulsator, and a motor is connected to the lower end of the rotating shaft. The motor is installed at the bottom of the outer shell. A plurality of ball bearings are arranged around the inner wall of the outer shell, and a circular track is provided on the outer wall of the cylindrical body, in which the ball bearings are installed.
[0004] Preferably, the inner wall surface of the cylinder is provided with a plurality of raised strips, which are configured in a corrugated structure.
[0005] Preferably, the upper end of the outer casing is provided with an end cap.
[0006] The beneficial effects of this utility model are: the structure of this utility model is reasonable and easy to use. By setting a track on the cylinder and cooperating with the ball bearings on the outer shell, the cylinder can always be kept in a stable state during the rotation of the cylinder, avoiding left and right shaking when the cylinder rotates. At the same time, the corrugated convex strips on the inner wall of the cylinder can increase the tumbling and impact force of the material in the cylinder, and improve the cleaning efficiency of the drum machine.

[0011] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0012] Unless otherwise stated, any feature in this specification may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is merely one example of a series of equivalent or similar features.
[0013] like Figure 1 , 2 The high-efficiency and stable vertical rotary drum machine shown includes an outer shell 1 and a cylindrical body 2. The cylindrical body 2 is installed inside the outer shell 1. A pulsator 3 is provided at the bottom of the cylindrical body 2. A rotating shaft 4 is provided at the lower end of the pulsator 3. A motor 5 is connected to the lower end of the rotating shaft 4. The motor 5 is installed at the bottom of the outer shell 1. A plurality of ball bearings 9 are arranged around the inner wall of the outer shell 1. A circular track 6 is provided on the outer wall of the cylindrical body 2. The ball bearings 9 are installed in the track 6.
[0014] The inner wall surface of the cylinder 2 is provided with a plurality of raised strips 7, the raised strips 7 being configured in a corrugated structure.
[0015] An end cap 8 is provided at the upper end of the outer shell 1.
[0016] During use, the materials and detergent are poured into the drum 2. After the materials and detergent are placed, the end cap 8 is closed. Then, the motor 5 drives the rotating shaft 4 to rotate, which in turn drives the impeller 3 to rotate forward and backward. This causes the drum 2 to rotate forward and backward, thereby cleaning the materials. During this process, when the drum 2 rotates, the ball bearings 9 will roll back and forth on the track 6, thus ensuring that the drum 2 will not shake when rotating normally, making the rotation of the drum 2 more stable, so as to better tumble and rub the materials inside the drum 2.
[0017] The protruding strip 7 increases the impact friction between the material and the inner wall of the cylinder 2, improving the efficiency of material cleaning. Furthermore, the corrugated structure of the protruding strip 7 prevents it from scratching the material when it collides with it. On the other hand, the corrugated structure of the protruding strip 7 further increases the impact friction between the material and the inner wall of the cylinder 2, making material cleaning more efficient.
[0018] The beneficial effects of this utility model are: the structure of this utility model is reasonable and easy to use. By setting a track on the cylinder and cooperating with the ball bearings on the outer shell, the cylinder can always be kept in a stable state during the rotation of the cylinder, avoiding left and right shaking when the cylinder rotates. At the same time, the corrugated convex strips on the inner wall of the cylinder can increase the tumbling and impact force of the material in the cylinder, and improve the cleaning efficiency of the drum machine.
[0019] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
