Description

Technical Field

[0001] The utility model relates to the technical field of stirring, in particular to a medicine stirrer with an air pressure self-balancing regulating mechanism. Background Art

[0002] The operating temperature of bearings on most existing pharmaceutical agitators generally does not exceed 80°. However, in the actual production process, the bearing temperature often rises due to insufficient bearing lubrication, excessive viscosity of lubricating oil, and bearing processing and installation. Excessive bearing temperature will cause material expansion, resulting in a decrease in mechanical clearance, noise and mechanical damage.

[0003] After searching, a Chinese patent with authorization announcement number CN221107787U discloses a technical solution to the problem of increased bearing temperature. The low-boiling-point liquid and the heat dissipation copper tube extending spirally upward cooperate to dissipate heat from the bearing, and is equipped with a manual pressure reduction unit for adjusting the air pressure in the annular cavity and the heat dissipation copper tube. However, the above heat dissipation method has some problems. When the heat dissipation speed of the heat dissipation copper tube is lower than the low-boiling-point vaporization speed, the air pressure in the inner cavity of the heat dissipation copper tube will increase. As the air pressure increases, the boiling point of the low-boiling-point liquid will increase, resulting in an increase in the vaporization temperature of the low-boiling-point liquid, which in turn makes it increasingly difficult for subsequent low-boiling-point liquids to vaporize. The low-boiling-point liquid cannot conduct the temperature on the bearing away in time, which will cause the bearing temperature to increase, affecting the heat dissipation of the bearing. Therefore, the present application provides a pharmaceutical agitator with an air pressure self-balancing adjustment mechanism to meet the needs. Utility Model Content

[0004] The purpose of the present application is to provide a pharmaceutical agitator with an air pressure self-balancing adjustment mechanism, which is used to solve the technical problem in the prior art that as the air pressure in the heat dissipation copper tube becomes higher and higher, the heat of the bearing cannot be transferred to the shaft in time.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example: Reference Figure 1 The pharmaceutical stirrer shown has an air pressure self-balancing adjustment mechanism, including a stirring motor 1 installed on a frame 3, the output shaft of the stirring motor 1 is connected to the stirring shaft 6 through a mounting shaft 2, the mounting shaft 2 passes through the frame 3, the outer sleeve of the mounting shaft 2 is provided with a bearing 4, and the bearing 4 is installed together with the frame 3 through an upper bearing seat 5, the inner cavity of the upper bearing seat 5 is provided with a liquid storage cavity 7, and the liquid storage cavity 7 stores a low-boiling point liquid, and the upper bearing seat 5 is provided with a heat dissipation copper tube 8 that is in communication with the inner cavity of the liquid storage cavity 7 and extends spirally upward. It also includes an air pressure self-balancing adjustment unit for ensuring the air pressure balance in the heat dissipation copper tube 8, so as to achieve good heat dissipation of the bearing 4 by the low-boiling point liquid.

[0019] As a preferred implementation in this embodiment, Figure 1 and Figure 2 As shown, the air pressure self-balancing adjustment unit includes a hollow cylinder 10 fixedly mounted on the frame 3 through a mounting plate 9, the hollow cylinder 10 is made of a heat-conducting material, the lower end of the hollow cylinder 10 is connected to the heat dissipation copper tube 8 through a conduit, the inner cavity of the hollow cylinder 10 is sealed and slidably provided with a gravity column 12, the lower end of the gravity column 12 is installed with an elastic sealing ring 13 that slides against the inner wall of the hollow cylinder 10, and the upper end of the gravity column 12 slides through a limit plate 11 installed on the frame 3.

[0020] During use, since the heat dissipating copper tube 8 is connected to the inner cavity of the hollow tube 10, when the air pressure inside the heat dissipating copper tube 8 increases to a certain value, its air pressure will cause the gravity column 12 to move upward. When more gas is added to the heat dissipating copper tube 8, its gravity column 12 will rise a certain distance accordingly to keep the air pressure in the inner cavity of the heat dissipating copper tube 8 stable, which is beneficial to timely heat dissipation of the bearing 4. Moreover, since the hollow tube 10 is made of heat-conducting material, the heat dissipation area of the gas is continuously increased while the gravity column 12 rises, which can accelerate the heat dissipation of the internal gas, is beneficial to the rapid reduction of the internal air pressure, and further improves the heat dissipation effect of the bearing 4.

[0021] It should be noted that, first, heat dissipation fins are provided on the outer wall of the hollow tube 10 (which can be made of copper material) to improve the heat dissipation effect of the hollow tube 10; second, a pressure gauge can be provided on the heat dissipation copper tube 8 to adjust the internal air pressure of the heat dissipation copper tube 8 according to the value of the pressure gauge.

[0022] As a preferred implementation in this embodiment, Figure 3 As shown, the gravity column 12 includes a movable column 121 with a U-shaped rod 124 at the upper end and a plurality of splicing columns 122 , and the lower ends of the plurality of splicing columns 122 are each provided with a rectangular limiting groove adapted to the U-shaped rod 124 .

[0023] The number of splicing columns 122 superimposed on the movable column 121 can be increased or decreased as needed to control the change of the initial air pressure value inside the heat dissipation copper tube 8 when the movable column 121 is pushed upward, thereby changing the heat dissipation effect of the low-boiling-point liquid on the bearing 4.

[0024] It should be noted that the U-shaped rod 124 is used in conjunction with the rectangular limiting groove. While having a limiting effect, the fingers can be inserted into the U-shaped rod 124 to lift it, thereby facilitating the transportation of the splicing column 122.

[0025] As a preferred implementation in this embodiment, Figure 1 and Figure 3 As shown, an oblique hole 125 is provided on the outer wall of each splicing column 122 obliquely upward, and a hanging rod 123 adapted to the oblique hole 125 is provided on the mounting plate 9.

[0026] The inclined hole 125 cooperates with the inclined hanging rod 123 to scrape the splicing column 122 onto the hanging rod 123, which facilitates the storage and placement of the splicing column 122. At the same time, the setting of the inclined hole 125 does not affect the movement of the splicing column 122 relative to the limit plate 11.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
