Description

Technical Field

[0001] This utility model relates to the field of mixing furnace technology, and in particular to a mixing furnace for a large pulping machine. Background Technology

[0002] In the lithium battery electrolyte preparation process, the stirring furnace is the core equipment for achieving uniform mixing of electrolyte raw materials. It and the pulping machine are independent structures used in conjunction with each other and need to be flexibly moved to designated positions according to the needs of the production process. At present, due to their large size and weight, the movement of large stirring furnaces mainly relies on mobile trolleys. The loading and unloading connection between the stirring furnace and the mobile trolley must be achieved by using a lifting platform for height adjustment: during loading and unloading, the stirring furnace is first raised to the same height as the mobile trolley's bearing surface by the lifting platform, and then pushed onto the trolley and fixed; unloading requires repeating the reverse operation. The existing mobile method has obvious technical drawbacks: on the one hand, the coordinated operation of the elevator and the mobile trolley is cumbersome, requiring manual cooperation from multiple positions, resulting in low transfer efficiency of the mixing furnace and seriously affecting the continuity of the electrolyte production process; on the other hand, the elevator is prone to shaking during the lifting process, which may not only cause the internal components of the mixing furnace to deviate in precision, but also poses a risk of tipping over, thereby affecting the mixing quality of the electrolyte; in addition, the additional configuration of the elevator increases the cost of equipment purchase and maintenance, while occupying a large amount of production space, making it difficult to adapt to the high-efficiency and compact process layout requirements in lithium battery production, thus restricting the improvement of production efficiency. Therefore, a mixing furnace with a large pulping machine is proposed to solve the problems mentioned above. Utility Model Content

[0003] This invention addresses the inconvenience of moving existing mixing furnaces by providing a mixing furnace for a large pulping machine. It enables rapid loading, unloading, and workstation transfer with a mobile trolley without relying on a lifting platform, simplifying the collaborative operation process of multiple devices, significantly shortening the transfer time of the mixing furnace from the storage area to the working area, effectively connecting the pulping machine operation process, significantly improving the continuity of electrolyte production, and effectively solving the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A mixing furnace for a large pulping machine includes a furnace body. The bottom of the furnace body is provided with a circular base, and the upper end of the circular base is provided with a lifting device for driving the furnace body to move up and down. The bottom of the circular base is provided with multiple moving wheels, and the lower end of the furnace body is provided with multiple arc-shaped expansion pads. When the furnace body moves downward, the multiple arc-shaped expansion pads can move downward and swing outward to unfold. When the furnace body moves upward, the multiple arc-shaped expansion pads can move upward and swing inward to close. The upper end of the outer surface of the furnace body is provided with a handle.

[0005] The lower end of the circular base is fixed with multiple connecting posts, and the movable wheels are all rotatably connected to the lower end of the corresponding connecting posts.

[0006] The furnace body is slidably connected to the inner wall of the circular base.

[0007] The lifting device includes multiple telescopic rods, the lower ends of which are fixed to the upper surface of the circular base; multiple extension seats are fixed to the outer surface of the furnace body, and the extension seats are fixed to the telescopic ends of the corresponding telescopic rods.

[0008] Multiple support seats are fixed to the lower end of the outer surface of the furnace body. The inner wall of the support seat is provided with a rotatable drive shaft, and the arc-shaped expansion pads are all fixed to the lower end of the outer surface of the drive shaft.

[0009] Each drive shaft has a fixed seat fixedly attached to its upper surface, and each fixed seat has a rotatable drive pin fixedly attached to its inner wall.

[0010] Multiple sector-shaped cylinders are fixed to the upper surface of the circular base, and each sector-shaped cylinder has a track groove on its inner wall that cooperates with the drive pin.

[0011] The track grooves all include inclined grooves and vertical grooves that cooperate with the drive pins.

[0012] Compared with the prior art, this utility model has the following advantages: In use, the device can be moved to a designated position via its casters; a lifting device can drive the furnace body to move upwards or downwards. Once in the designated position, directly below the mixing machine, the lifting device allows the furnace body to move downwards, bringing its lower surface into contact with the ground. Simultaneously, multiple arc-shaped expansion pads move downwards and tumble outwards, expanding to ensure safety when the furnace is placed on the ground and preventing tipping. This device allows for rapid loading, unloading, and relocation with a mobile trolley without relying on a lift, simplifying multi-device collaborative operations and significantly reducing the time required to transfer the mixing furnace from the storage area to the working area. This system effectively connects the pulping machine operation process, significantly improving the continuity of electrolyte production; it optimizes the stability of loading, unloading, and transfer processes, reducing the impact of vibration and shaking on the mixing furnace, preventing internal component precision deviations, and preventing uneven composition of electrolyte raw materials due to shaking during transfer, further improving the consistency and pass rate of electrolyte preparation; it eliminates the need for auxiliary equipment such as elevators, reducing equipment purchase and maintenance costs, while saving production space occupied by auxiliary equipment, adapting to the compact layout of lithium battery production, and reducing site usage costs; it simplifies the loading and unloading operation steps of the mixing furnace, reducing the difficulty of manual coordination, avoiding safety hazards caused by improper coordination of multiple devices, while also reducing manual labor intensity and improving the efficiency of the production process. Safety and operational reliability are better suited to the needs of large-scale industrial production. The furnace body's built-in lifting function allows for precise control of the descent process. Combined with the linkage design of the lower arc-shaped expansion pad, as the furnace body moves downwards, the expansion pad simultaneously flips and unfolds outwards, significantly increasing the contact area between the furnace body and the ground, forming a wide and stable support structure. Compared to traditional placement methods that rely solely on a small contact area at the bottom, this design effectively disperses the weight pressure of large stirring furnaces, fundamentally solving the risk of tipping due to a shifted center of gravity or slight unevenness in the ground. It is particularly suitable for heavy-duty conditions in electrolyte preparation scenarios where the furnace body is fully loaded with raw materials, providing dual safety guarantees for equipment, operators, and the surrounding production environment. The lifting function and expansion pad unfolding... The synchronized operation eliminates the need for additional manual adjustments to the support structure, avoiding the cumbersome process of separately installing support components when placing the traditional furnace body. It also ensures that the expansion pad is fully deployed and forms a stable support when the furnace body is lowered to the ground, achieving an integrated connection between lifting, supporting, and placing. Even on uneven production ground, the deployed expansion pad can adapt to the ground condition through multi-directional contact, further improving the stability of the furnace body when stationary and preventing positional displacement due to slight vibrations or collisions. There is no need to configure additional anti-tipping brackets, fixed counterweights, or other auxiliary safety equipment. Safe placement is achieved through the furnace body's own structural design, which reduces the purchase and maintenance costs of auxiliary equipment and eliminates the steps of manually installing and disassembling protective devices.Operators only need to control the furnace body's lifting and lowering to safely place it, significantly simplifying the safety operation process, reducing manual intervention, and avoiding secondary safety risks caused by improper installation of auxiliary protective devices. The improved furnace stability effectively prevents furnace damage, electrolyte leakage, or raw material waste due to tipping, reducing equipment downtime for maintenance, ensuring continuous production, and mitigating environmental pollution, raw material loss, and personnel safety risks caused by electrolyte leakage. This indirectly reduces the economic and safety costs of production accidents and further strengthens risk management capabilities in industrial production. Attached Figure Description

Detailed Implementation

[0018] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figures 1-4 As shown, this utility model provides a mixing furnace for a large pulping machine, including a furnace body 2. The bottom of the furnace body 2 is provided with a circular base 1, and the upper end of the circular base 1 is provided with a lifting device for driving the furnace body 2 to move up and down. The bottom of the circular base 1 is provided with multiple moving wheels 4, and the lower end of the furnace body 2 is provided with multiple arc-shaped expansion pads 11. When the furnace body 2 moves downward, the multiple arc-shaped expansion pads 11 can move downward and swing outward to unfold. When the furnace body 2 moves upward, the multiple arc-shaped expansion pads 11 can move upward and swing inward to close. The upper end of the outer surface of the furnace body 2 is provided with a handle 3.

[0020] like Figures 1-3As shown, the circular base 1 supports and fixes the entire device, and also supports the furnace body 2 during movement. The movable wheels 4 allow the device to be moved to a designated position. The lifting device allows the furnace body 2 to move upwards or downwards. After moving to the designated position, where the furnace body 2 is directly below the pulping machine, the lifting device can be controlled to move the furnace body 2 downwards or upwards. When the furnace body 2 moves downwards, its lower end can contact the ground, simultaneously driving multiple arc-shaped expansion pads 11 to follow the downward movement of the furnace body 2 while simultaneously rotating and swinging outwards, allowing the arc-shaped expansion pads 11 to unfold outwards. This ensures greater safety when the furnace body 2 is placed on the ground, preventing it from tipping over. When the furnace body 2 moves upwards, the multiple arc-shaped expansion pads 11 can also be moved upwards. The expansion pad 11 folds inward for storage, reducing space occupation during movement; the handle 3 facilitates control and movement of the device; it allows for rapid loading, unloading, and workstation transfer with the mobile trolley without relying on a lift, simplifying multi-equipment collaborative operation processes, significantly shortening the transfer time of the mixing furnace from the storage area to the work area, effectively connecting the pulping machine operation process, and significantly improving the continuity of electrolyte production; it optimizes the stability of the loading, unloading, and transfer process, reducing the impact of vibration and shaking on the mixing furnace, avoiding internal component precision deviations, and preventing uneven composition of electrolyte raw materials due to shaking during transfer, further improving the consistency and pass rate of electrolyte preparation; it eliminates the need for auxiliary equipment such as lifts, reducing equipment purchase and maintenance costs, while... This design saves production space occupied by auxiliary equipment, adapts to the compact layout of lithium battery production, and reduces site usage costs. It simplifies the loading and unloading procedures of the mixing furnace, reduces the difficulty of manual coordination, avoids safety hazards caused by improper coordination of multiple devices, reduces labor intensity, and improves the safety and reliability of the production process, better meeting the needs of large-scale industrial production. The furnace body 2's built-in lifting function can precisely control the descent process. Combined with the linkage design of the lower arc-shaped expansion pad 11, when the furnace body 2 moves downward, the expansion pad synchronously flips and unfolds outward, significantly increasing the contact support area between the furnace body 2 and the ground, forming a wide and stable support structure. Compared to the traditional placement method that relies only on a small contact area at the bottom, this design can effectively distribute the weight pressure of the large mixing furnace, fundamentally reducing the burden on the furnace. This design effectively solves the risk of tipping over caused by a shift in the center of gravity or slight unevenness of the ground in furnace body 2. It is especially suitable for heavy-duty operations in electrolyte preparation scenarios where furnace body 2 is fully loaded with raw materials, providing dual safety protection for equipment, operators, and the surrounding production environment. The synchronization of the lifting function and the expansion pad deployment eliminates the need for additional manual adjustment of the support structure. This avoids the cumbersome operation of adding a separate support when placing furnace body 2, and ensures that the expansion pad is fully deployed and forms a stable support when furnace body 2 is lowered to the ground, achieving integrated connection of lifting, support, and placement. Even on uneven production ground, the deployed expansion pad can adapt to the ground condition through multi-directional contact, further improving the stability of furnace body 2 when stationary and preventing positional shifts caused by slight vibrations or collisions.No additional anti-tipping supports, fixed counterweights, or other auxiliary safety equipment are required. The furnace body 2's own structural design ensures safe placement, reducing the purchase and maintenance costs of auxiliary equipment and eliminating the need for manual installation and disassembly of protective devices. Operators only need to control the raising and lowering of the furnace body 2 to complete the safe placement, significantly simplifying the safety operation process, reducing manual intervention, and avoiding secondary safety risks caused by improper installation of auxiliary protective devices. The improved stability of the furnace body 2 effectively prevents damage to the furnace body 2, electrolyte leakage, or raw material waste caused by tipping. This reduces equipment downtime for maintenance, ensures continuous production, and avoids environmental pollution, raw material loss, and personnel safety risks caused by electrolyte leakage. It indirectly reduces the economic and safety costs of production accidents and further strengthens risk management capabilities in industrial production.

[0021] The lower end of the circular base 1 is fixedly connected to multiple connecting posts 5, and the movable wheels 4 are all rotatably connected to the lower end of the corresponding connecting posts 5.

[0022] like Figures 1-2 As shown, the movable wheel 4 is existing technology and will not be described in detail; the movable wheel 4 is rotatably connected to the lower end of the connecting column 5, which can change the direction of the movable wheel 4, thereby automatically adjusting according to the movement requirements.

[0023] The furnace body 2 is slidably connected to the inner wall of the circular base 1.

[0024] like Figure 1 As shown, the furnace body 2 can slide up and down the inner wall of the circular base 1.

[0025] The lifting device includes multiple telescopic rods 7, the lower ends of which are fixed to the upper surface of the circular base 1; multiple extension seats 8 are fixed to the outer surface of the furnace body 2, and the extension seats 8 are fixed to the telescopic ends of the corresponding telescopic rods 7.

[0026] like Figure 2 As shown, when the telescopic rod 7 is working, it can drive the furnace body 2 to move up and down; the telescopic rod 7 is existing technology and will not be described in detail.

[0027] Multiple support seats 9 are fixedly connected to the lower end of the outer surface of the furnace body 2. The inner wall of the support seat 9 is provided with a rotatable drive shaft 10. The arc-shaped expansion pads 11 are all fixedly connected to the lower end of the outer surface of the drive shaft 10.

[0028] like Figure 3 As shown, the support base 9 provides support and limits the drive shaft 10, the arc-shaped expansion pad 11, etc.; when the drive shaft 10 rotates, it can drive the arc-shaped expansion pad 11 to flip outward or flip inward to close.

[0029] Each drive shaft 10 has a fixed seat 12 fixedly attached to its upper surface, and each fixed seat 12 has a rotatable drive pin 13 fixedly attached to its inner wall.

[0030] like Figure 4 As shown, when the drive pin 13 rotates and moves, it can drive the fixed base 12 and the drive shaft 10 to rotate, thereby controlling the opening and closing of the arc-shaped expansion plate.

[0031] Multiple sector-shaped cylinders 14 are fixedly connected to the upper surface of the circular base 1, and the inner wall of each sector-shaped cylinder 14 is provided with a track groove that cooperates with the drive pin 13.

[0032] like Figure 3 As shown, the center of the sector cylinder 14 is collinear with the center of the drive shaft 10, so that it can always mesh with the track groove when the drive pin 13 moves circumferentially.

[0033] Each of the track grooves includes an inclined groove 16 and a vertical groove 17 that cooperate with the drive pin 13.

[0034] like Figure 3 As shown, when the furnace body 2 moves downward, it can drive the support base 9, drive shaft 10, drive pin 13, and arc-shaped expansion pad 11 to move downward synchronously. When the drive pin 13 moves downward, it can rotate and the drive shaft 10 can rotate under the meshing of the inclined groove 16. That is, the corresponding arc-shaped expansion pad 11 flips outward and unfolds. When the furnace body 2 continues to move downward, it can cause the drive pin 13 to move downward and enter the inner wall of the vertical groove 17. At this time, the drive pin 13 no longer rotates and only moves vertically downward. The corresponding arc-shaped expansion pad 11 is in a fully unfolded state and will follow the furnace body 2 to move vertically downward until it contacts the ground. When the furnace body 2 moves upward, the arc-shaped expansion pad 11 closes inward and resets. This will not be described in detail.

[0035] In use, this invention allows the device to be moved to a designated position via the movable wheels 4. A lifting device enables the furnace body 2 to move upwards or downwards. Once in the designated position, directly below the mixing machine, the lifting device lowers the furnace body 2, allowing its lower surface to contact the ground. Simultaneously, multiple arc-shaped expansion pads 11 move downwards with the furnace body 2, rotating and swinging outwards to expand. This ensures greater safety when the furnace body 2 is placed on the ground, preventing it from tipping over. This device eliminates the need for a lift, enabling rapid loading, unloading, and relocation with a mobile trolley, simplifying multi-device collaborative operation and significantly shortening the time required for storing the mixing furnace. The reduced transfer time from the production area to the work area effectively connects the pulping machine operation process, significantly improving the continuity of electrolyte production; it optimizes the stability of loading, unloading, and transfer processes, reducing the impact of vibration and shaking on the mixing furnace, avoiding misalignment of internal components, and preventing uneven composition of electrolyte raw materials due to shaking during transfer, further improving the consistency and pass rate of electrolyte preparation; it eliminates the need for auxiliary equipment such as elevators, reducing equipment purchase and maintenance costs, while saving production space occupied by auxiliary equipment, adapting to the compact layout of lithium battery production, and reducing site usage costs; it simplifies the loading and unloading operation steps of the mixing furnace, reduces the difficulty of manual coordination, avoids safety hazards caused by improper coordination of multiple devices, and reduces labor intensity, improving production efficiency. The safety and operational reliability of the process are better suited to the needs of large-scale industrial production. The built-in lifting function of the furnace body 2 can precisely control the descent process. With the linkage design of the lower arc-shaped expansion pad 11, when the furnace body 2 moves downward, the expansion pad simultaneously flips and swings outward and unfolds, which can significantly increase the contact support area between the furnace body 2 and the ground, forming a wide and stable support structure. Compared with the traditional placement method that only relies on a small contact area at the bottom, this design can effectively distribute the weight pressure of the large stirring furnace, fundamentally solving the risk of tipping over caused by the center of gravity shift of the furnace body 2 or slight unevenness of the ground. It is especially suitable for heavy working conditions when the furnace body 2 is fully loaded with raw materials in the electrolyte preparation scenario, providing double safety protection for equipment, operators and the surrounding production environment. The lifting function and expansion pad 11 are linked together. The synchronous unfolding of the pad eliminates the need for additional manual adjustments to the support structure. This avoids the cumbersome operation of separately installing support components when placing the traditional furnace body 2, and ensures that the expanded pad is fully unfolded and forms a stable support when the furnace body 2 is lowered to the ground, achieving an integrated connection between lifting, supporting, and placing. Even on uneven production ground, the unfolded pad can adapt to the ground condition through multi-directional contact, further improving the stability of the furnace body 2 when stationary and preventing positional displacement due to slight vibrations or collisions. There is no need to configure additional anti-tipping brackets, fixed counterweights, or other auxiliary safety equipment. Safe placement is achieved through the structural design of the furnace body 2 itself, which reduces the purchase and maintenance costs of auxiliary equipment and eliminates the steps of manually installing and disassembling protective devices.Operators only need to control the lifting and lowering of furnace body 2 to safely place it, greatly simplifying the safe operation process, reducing manual intervention, and avoiding secondary safety risks caused by improper installation of auxiliary protective devices. The improved stability of furnace body 2 effectively prevents damage to furnace body 2, electrolyte leakage, or raw material waste due to tipping, reducing equipment downtime for maintenance, ensuring continuous production, and avoiding environmental pollution, raw material loss, and personnel safety risks caused by electrolyte leakage. This indirectly reduces the economic and safety costs caused by production accidents and further strengthens risk management capabilities in industrial production.
