DETAILED DESCRIPTION

[0019] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0022] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0023] The present application is further described below with reference to the accompanying drawings:

[0024] like Figure 1 to Figure 2As shown, the present application provides a cooling system with multiple cooling modules for stirring, including a frame 1 and a stirring shaft 2, the stirring shaft 2 is rotatably arranged on the frame 1, a connecting position 3 is formed between the frame 1 and the stirring shaft 2, the frame 1 and the stirring shaft 2 are contacted and connected at the connecting position 3, so that the frame 1 supports the stirring shaft 2 and keeps the stirring shaft 2 rotating stably.

[0025] A first cooling module 4 is arranged between the frame 1 and the stirring shaft body 2. A cooling cavity 41 is arranged on the first cooling module 4. The cooling cavity 41 is suitable for circulating cooling liquid. The cooling cavity 41 is arranged on the connecting position 3 and / or the surrounding side of the stirring shaft body 2. Cooling liquid can be poured into the cooling cavity 41. The cooling liquid can absorb heat around the cooling cavity 41, thereby cooling the structure near the first cooling module 4.

[0026] It can be understood that when the cooling chamber 41 is arranged on the peripheral side of the connecting position 3, it can perform heat exchange cooling on the frame 1, the stirring shaft body 2, and the connecting structure between the frame 1 and the stirring shaft body 2; when the cooling chamber 41 is arranged on the peripheral side of the stirring shaft body 2, it can perform heat exchange cooling on the stirring shaft body 2, and the structure, shape and specific position of the cooling chamber 41 can be arranged according to actual needs.

[0027] like Figures 1 to 2 In the illustrated embodiment, a specific method for circulating the coolant in the cooling cavity 41 is that a coolant inlet 411 and a coolant outlet 412 are provided on the cooling cavity 41, the coolant is injected through the coolant inlet 411, and the coolant flows out through the coolant outlet 412. Furthermore, the height of the coolant inlet 411 is lower than the height of the coolant outlet 412, so that when the coolant inlet 411 and the coolant outlet 412 are continuously open, the cooling cavity 41 can always accumulate coolant at a position below the height of the coolant outlet 412, thereby obtaining a higher upper limit of the heat storage capacity, so as to absorb more heat transferred from the cooling cavity 41, reduce waste of resources, and reduce costs.

[0028] like Figures 1 to 2 In the illustrated embodiment, the coolant outlet 412 is close to the top of the cooling chamber 41, and the coolant inlet 411 is close to the bottom of the cooling chamber 41, so that the cooling chamber 41 is filled with coolant as much as possible, thereby increasing the contact area between the coolant and the cooling chamber 41, thereby improving the heat exchange effect, and further improving the cooling efficiency of the first cooling module 4.

[0029] like Figures 1 to 2 In the illustrated embodiment, the coolant outlet 412 and the coolant inlet 411 are both located outside the cooling cavity 41 , which facilitates connection with external pipelines, reduces structural interference, and facilitates installation.

[0030] A second cooling module 5 is arranged on the peripheral side of the stirring shaft body 2, and a heat exchange portion 51 is formed on the second cooling module 5 toward the first cooling module 4. There is a gap between the heat exchange portion 51 and the cooling chamber 41, and the heat exchange portion 51 and the cooling chamber 41 are suitable for exchanging heat. The heat exchange portion 51 can absorb the heat of the stirring shaft body 2 and then transfer it to the vicinity of the cooling chamber 41. Since the interior of the cooling chamber 41 is constantly being cooled, the temperature of the cooling chamber 41 will be lower than the temperature of the heat exchange portion 51, so that the temperature of the heat exchange portion 51 can be more easily transferred to the cooling chamber 41, thereby indirectly assisting the stirring shaft body 2 in cooling down.

[0031] It is worth noting that the smaller the gap between the heat exchange part 51 and the cooling chamber 41, the higher the heat exchange efficiency. However, when the stirring shaft 2 rotates, structural interference is more likely to occur between the heat exchange part 51 and the cooling chamber 41. Therefore, in actual design, the gap between the heat exchange part 51 and the cooling chamber 41 should not be too small.

[0032] like Figures 1 to 2 In the illustrated embodiment, at least one branch portion 511 and at least one receiving groove 413 are respectively provided on opposite sides of the heat exchange portion 51 and the cooling chamber 41 along the circumference of the stirring shaft body 2, the branch portions 511 are suitable for being fitted and embedded in the receiving grooves 413 one by one, and there is a gap between the branch portions 511 and the receiving grooves 413, the branch portions 511 and the receiving grooves 413 are suitable for exchanging heat, in the present application, usually, the branch portions 511 are arranged on the heat exchange portion 51, and the receiving grooves 413 are arranged on the cooling chamber 41, the branch portions 511 can be regarded as cooling fins arranged on the heat exchange portion 51, and the receiving grooves 413 are used to increase the heat exchange area between the branch portions 511, thereby improving the heat exchange efficiency between the heat exchange portion 51 and the cooling chamber 41, realizing efficient heat conduction, and helping the stirring shaft body 2 to cool down faster.

[0033] In some embodiments, the coordination between the branch portion 511 and the receiving groove 413 can be designed as a maze structure. The more complex the branch portion 511 and the receiving groove 413 are, the larger the heat exchange area will be. Before the heat exchange efficiency exceeds the thermal conductivity efficiency of the branch portion 511 itself, appropriately increasing the structural complexity of the branch portion 511 and the receiving groove 413 will help improve the cooling effect on the stirring shaft 2.

[0034] It is understandable that, the greater the number of branch portions 511 and receiving grooves 413 , the more directly the cooling effect on the stirring shaft 2 can be improved.

[0035] like Figures 1 to 2In the illustrated embodiment, the stirring shaft body 2 is arranged in the vertical direction, and the number of connecting positions 3 is two, which are respectively close to the two ends of the stirring shaft body 2. A support seat 11 is arranged at the lower connecting position 3, and the bottom of the cooling chamber 41 is the support seat 11. The receiving groove 413 is opened on the support seat 11. The cooling chamber 41 uses the structure formed by the support seat 11 to reduce the use of parts and improve the compactness of the structure. In addition, in order to ensure the supporting effect on parts such as the bearing 6, the thickness of the support seat 11 is generally large. In addition to better heat exchange effect and convenient cooling of the cooling chamber 41, the receiving groove 413 can also be more reasonably opened on the support seat 11, reducing the distance between the coolant in the cooling chamber 41 and the branch portion 511 set in the heat exchange portion 51, thereby effectively improving the heat exchange efficiency.

[0036] like Figure 2 In the illustrated embodiment, a receiving cavity 111 is provided below the support seat 11, and the receiving cavity 111 is suitable for accommodating the second cooling module 5. The receiving groove 413 is provided in the receiving cavity 111, and the receiving cavity 111 is used to protect the second cooling module 5, while being able to further increase the heat exchange efficiency between the second cooling module 5 and the cooling cavity 41 on the support seat 11.

[0037] like Figure 2 In the shown embodiment, the second cooling module 5 is located below the cooling chamber 41 at the lower connecting position 3, which can also be understood as the second cooling module 5 being located below the support seat 11. Since in traditional stirring equipment, the bottom of the stirring shaft 2 is used to install paddles to stir high-temperature materials, the temperature of the lower part of the stirring shaft 2 is usually higher. The second cooling module 5 can cooperate with the first cooling module 4 to efficiently cool and dissipate heat for the stirring condition of the lower part of the stirring shaft 2, thereby improving the use stability and service life of the stirring shaft 2.

[0038] like Figures 1 to 2 In the illustrated embodiment, the frame 1 and the stirring shaft 2 are connected by a bearing 6 at the connection position 3, and a cooling chamber 41 is arranged on the peripheral side of the bearing 6. The cooling chamber 41 can cool the bearing 6 and the structure near the bearing 6, thereby improving the stability and service life of the bearing 6.

[0039] like Figures 1 to 2 In the illustrated embodiment, the cooling cavity 41 is arranged on the lower side and the outer peripheral side of the bearing 6, and can cover the surrounding of the bearing 6 as much as possible, thereby improving the cooling effect by increasing the contact area. At the same time, the arrangement of the cooling cavity 41 does not affect the disassembly and maintenance of the bearing 6, so that the bearing 6 can be opened and taken out from the top. In addition, the position design of the cooling cavity 41 can also play a role in strengthening the support of the bearing 6, improving the structural strength below the bearing 6, and reducing the probability of deformation.

[0040] In some embodiments, the first cooling module 4 includes a monitoring device, which is suitable for monitoring the operating temperature at the stirring shaft 2 to adjust the flow rates of the cooling liquid inlet 411 and the cooling liquid outlet 412 .

[0041] In some embodiments, the monitoring device is a temperature transmitter, which can monitor the operating temperature of the equipment in real time, and improve resource utilization and reduce energy consumption and costs by automatically adjusting the coolant flow in the cooling chamber 41.

[0042] like Figure 1 In the shown embodiment, a third cooling module 7 is provided between the frame 1 and the stirring shaft body 2, and the third cooling module 7 is located between the two connecting positions 3. The third cooling module 7 is suitable for cooling the stirring shaft body 2 between the two connecting positions 3. The third cooling module 7 is mainly used to cool the exposed part of the stirring shaft body 2 that is not connected. In conjunction with the first cooling module 4 and the second cooling module 5, the complete cooling of the stirring shaft body 2 as a whole and the connecting structure between the stirring shaft body 2 and the frame 1 can be achieved, thereby ensuring the normal operation of each structure.

[0043] In some embodiments, the third cooling module 7 is suitable for contactless cooling of the stirring shaft 2. The third cooling module 7 is arranged on the peripheral side of the stirring shaft 2. The third cooling module 7 includes a fan. The fan is suitable for blowing out airflow, and at least part of the airflow is suitable for contacting the stirring shaft 2. The airflow is used to take away the heat on the surface and vicinity of the stirring shaft 2 to achieve the purpose of cooling.

[0044] In some embodiments, the number of fans is one, and the direction of airflow blown by the fan is parallel to a plane perpendicular to the axial direction of the stirring shaft 2 , or the direction of airflow blown by the fan is parallel to the axial direction of the stirring shaft 2 .

[0045] In some embodiments, there are multiple fans, and the direction of the airflow blown by the fans is parallel to a plane perpendicular to the axial direction of the stirring shaft 2 , and / or the direction of the airflow blown by the fans is parallel to the axial direction of the stirring shaft 2 .

[0046] It can be understood that when the direction of the airflow blown by the fan is parallel to the plane perpendicular to the axial direction of the stirring shaft body 2, the fan can be regarded as blowing directly at the surface of the stirring shaft body 2, and the area of ​​the airflow contacting the stirring shaft body 2 is smaller, but the cooling effect is better; when the direction of the airflow blown by the fan is parallel to the axial direction of the stirring shaft body 2, the airflow can flow along the surface of the stirring shaft body 2, and the area of ​​the airflow contacting the stirring shaft body 2 is larger, but the cooling effect is relatively general. The two methods can be used alone or in combination according to actual needs, so as to obtain the best cooling effect on the stirring shaft body 2.

[0047] In combination with the situation in which the bottom of the stirring shaft 2 in the conventional stirring equipment of the above embodiment is used to install paddles for stirring high-temperature materials, the direction of the air flow blown out by at least part of the fan can be set to flow upward along the surface of the stirring shaft 2, so as to form an upward-flowing air flow field under the stirring shaft 2. In this way, the air flow blown out by the fan will not affect the stirring process of the material, but can also quickly take away the heat under the stirring shaft 2, thereby reducing the heat accumulation under the stirring shaft 2.

[0048] The above describes the basic principles, main features and advantages of the present application. Technical personnel in this industry should understand that the present application is not limited to the above embodiments. The above embodiments and the specification only describe the principles of the present application. Without departing from the spirit and scope of the present application, the present application will also have various changes and improvements. These changes and improvements all fall within the scope of the present application for which protection is sought.
