Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device for stirring cryosomnium liquid. Background Art

[0002] The motor is provided with oil as lubricant to make the stirring motor work normally, and the stirring motor is also provided with a sealing gasket inside. The sealing gasket is elastic and used to prevent the leakage of liquid oil, such as a brushless motor with Chinese patent announcement number CN205670739U. For the motor used as a stirring paddle, the motor heats up when driving the stirring paddle to rotate. In a high temperature environment, the sealing gasket becomes softer, so that the sealing performance is better.

[0003] Cryo-sleeping liquid is used as a refrigerant in cryo-sleeping technology. Cryo-sleeping technology uses low temperature and ultra-low temperature technology to directly contact the frozen objects through cryo-sleeping liquid as a refrigerant. The frozen objects, such as aquatic products, meat, fruits and vegetables, are directly frozen and preserved in the freezing liquid within 6 to 30 minutes, and the cell membranes of the frozen objects are not frozen and cracked. The cryo-sleeping liquid in the cryo-sleeping technology usually has an operating temperature range of -30℃ to -40℃. The stirring paddle in the current stirring device of the cryo-sleeping liquid is fixedly connected to the rotating shaft of the motor. During the stirring process of the cryo-sleeping liquid by the stirring paddle, the heat of the motor is quickly transferred to the stirring paddle, which not only causes the temperature of the cryo-sleeping liquid to rise, but also causes the sealing gasket inside the motor to freeze, harden and become brittle, causing lubricant leakage and reducing the service life of the motor.

[0053] The technical solution of the utility model is further described in conjunction with the following embodiments.

[0054] Example 1

[0055] A stirring device for stirring a cryo-hibernation liquid, such as Figure 1 , Figures 3 to 5 As shown, a motor, a stirring paddle 300 and a connecting mechanism 100 for blocking heat conduction between the stirring paddle 300 and the rotating shaft 200 of the motor are provided, the rotating shaft 200 is fixedly assembled with the upper part of the connecting mechanism 100, the stirring paddle 300 is fixedly assembled with the lower part of the connecting mechanism 100, and the rotating shaft 200 does not contact the stirring paddle 300. The thermal conductivity of the connecting mechanism 100 is smaller than the thermal conductivity of the stirring paddle 300 and the thermal conductivity of the rotating shaft 200.

[0056] The stirring paddle structure is common knowledge in the art, and the stirring paddle is not the focus of the invention of the present invention, so in the drawings of the present invention, the stirring paddle 300 is only partially shown, that is, only the end of the stirring paddle 300 and the connecting mechanism 100 is shown, and the other end structure of the stirring paddle 300, such as the functional structure of the blade, is not shown. The other structures of the motor are common knowledge in the art, and the other structures of the motor are not the focus of the invention of the present invention, so the other structures of the motor are not shown in the drawings, and only the rotating shaft 200 is shown.

[0057] The connecting mechanism 100 is provided with an upper assembly end and a lower assembly end, the upper assembly end is integrally connected with the lower assembly end, and the upper assembly end is located above the lower assembly end, the rotating shaft 200 is fixedly assembled with the upper assembly end, and the stirring paddle 300 is fixedly assembled with the upper assembly end. The rotating shaft 200 does not contact the stirring paddle 300. The upper assembly end and the lower assembly end are perpendicular to each other.

[0058] It should be noted that the upper assembly end and the lower assembly end are perpendicular to each other, which can improve the overall strength of the connection mechanism 100.

[0059] The upper assembly end and the lower assembly end are respectively connected to the same connecting structure surface 160 as a whole; the upper assembly end and the connecting structure surface 160 enclose a closed ring structure, which is defined as the upper assembly ring 110; the lower assembly end and the connecting structure surface 160 enclose another closed ring structure, which is defined as the lower assembly ring 120.

[0060] The upper surface of the upper assembly ring 110 is provided with an upper assembly hole 111, and the rotating shaft 200 passes through the upper assembly hole 111 into the ring of the upper assembly ring 110, and the rotating shaft 200 is fixedly assembled with the upper assembly hole 111; the lower surface of the lower assembly ring 120 is provided with a lower assembly hole 121, and the stirring paddle 300 passes through the lower assembly hole 121 into the ring of the lower assembly ring 120, and the stirring paddle 300 is fixedly assembled with the lower assembly hole 121, as shown in FIG. Figure 2 shown.

[0061] The upper assembly hole 111 is located directly above the lower assembly hole 121 ; the central axis of the stirring paddle 300 is colinear with the central axis of the rotating shaft 200 .

[0062] The thermal conductivity of the connecting mechanism 100 is less than or equal to 1 w / mK; the thermal conductivity of the stirring paddle 300 is greater than or equal to 15 w / nK; and the thermal conductivity of the rotating shaft 200 is greater than or equal to 15 w / nK.

[0063] The connecting mechanism 100 is an engineering plastic connecting mechanism 100 ; the rotating shaft 200 is a stainless steel rotating shaft 200 ; and the stirring paddle 300 is a stainless steel stirring paddle 300 .

[0064] It should be noted that the engineering plastics can be polyamide, polycarbonate, polyoxymethylene, modified polyphenylene ether and thermoplastic polyester, and the connecting mechanism 100 of the present embodiment is specifically a polyamide connecting mechanism 100. The thermal conductivity of polyamide is 0.33w / mK. Compared with stainless steel, the thermal conductivity of the connecting mechanism 100 is significantly smaller than that of the stirring paddle 300 and the rotating shaft 200. Therefore, the connecting mechanism 100 can effectively block the heat conduction channel between the rotating shaft 200 and the stirring paddle 300, prevent the sealing gasket from freezing and hardening and brittleness, and extend the service life of the motor. At the same time, it can also prevent the heat generated by the motor from being conducted to the stirring paddle 300, thereby increasing the temperature of the cryosleep liquid. Moreover, the rigidity of the engineering plastics is large, and the strength between the rotating shaft 200 and the stirring paddle 300 is high, which can ensure the transmission connection between the rotating shaft 200 and the stirring paddle 300, and will not affect the stirring effect.

[0065] The stirring device for stirring the frozen liquid connects the stirring paddle 300 and the rotating shaft 200 by using a connecting mechanism 100 with a low thermal conductivity, thereby blocking the heat conduction channel between the rotating shaft 200 and the stirring paddle 300, preventing the sealing gasket from freezing and becoming hard and brittle, and extending the service life of the motor. At the same time, it can also prevent the heat generated by the motor from being conducted to the stirring paddle 300, thereby increasing the temperature of the frozen liquid.

[0068] It should be noted that the function of the reinforcing ribs is to improve the overall strength of the connecting mechanism 100 .

[0069] The reinforcing rib connected to the upper assembly ring 110 is defined as the first reinforcing rib 130; the reinforcing rib connected to the lower assembly ring 120 is defined as the second reinforcing rib 140; the first reinforcing rib 130 extends from the outer surface of one side of the upper assembly ring 110 to the lower surface of the connecting structure surface 160, and then extends to the outer surface of the other side of the upper assembly ring 110; the second reinforcing rib 140 extends from the outer surface of one side of the lower assembly ring 120 to the upper surface of the connecting structure surface 160, and then extends to the outer surface of the other side of the lower assembly ring 120; the second reinforcing rib 140 and the first reinforcing rib 130 are perpendicular to each other.

[0070] It should be noted that the first reinforcing rib 130 and the second reinforcing rib 140 are perpendicular to each other, so as to further improve the overall strength of the connecting mechanism 100 .

[0071] The reinforcing rib is a hollow structure; the reinforcing rib is provided with a plurality of pairs of ventilation holes 150 disposed opposite to each other, and each pair of ventilation holes 150 is respectively located on two sides of the hollow structure.

[0072] It should be noted that the hollow structure reinforcement ribs and the opposite ventilation holes 150 can reduce the overall weight of the connection mechanism 100. Moreover, the hollow structure reinforcement ribs and the opposite ventilation holes 150 form an air insulation layer inside the reinforcement ribs, further blocking the heat conduction channel between the rotating shaft 200 and the stirring paddle 300.

[0073] Compared with the first embodiment, the present embodiment can further improve the strength of the connection mechanism 100 and further improve the connection reliability between the rotating shaft 200 and the stirring paddle 300 .

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
