Description

Technical Field

[0001] The present invention relates to the technical field of cable material processing, in particular to a heat-insulating flame-retardant high-voltage cable material processing device. Background Art

[0002] In the field of modern power transmission, high-voltage cables are the key carriers of electric energy transmission, and their performance is directly related to the stable operation of the power system. As the core component of high-voltage cables, heat-insulating and flame-retardant high-voltage cable materials play a decisive role in the safe and reliable operation of cables. Cable materials usually have high viscosity, which makes the fluidity of materials worse during the mixing process. Viscous materials are easy to adhere to the stirring blades and the inner wall of the stirring equipment, forming material accumulation, resulting in the weakening of the relative movement between the stirring blades and the material, and the inability to effectively transfer the shear force to the material, affecting the mixing effect.

[0003] For example, the existing Chinese patent with publication number CN216654314U discloses a stirring and mixing device for processing semi-rigid flame-retardant PVC high-voltage cable materials. The material is introduced into the stirring box, and the drive motor is started. The drive motor drives the drive shaft to rotate, and the drive shaft drives the second sleeve to rotate through the limit mechanism. The second sleeve drives the stirring rod to rotate. At the same time, the electric push rod drives the first sleeve to move up and down, and the first sleeve drives the second sleeve to move up and down. The stirring rod moves up and down while rotating, so that the stirring rod can move up and down during the rotation process, the stirring range is large, there is no dead angle, and the material is mixed more evenly.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: 1. Due to the high viscosity of the cable material, it is easy to adhere to the outside of the stirring shaft during the rotation of the stirring shaft. The adhesion of the cable material on the stirring shaft can easily cause local overheating. The cable material adhered to the stirring shaft will undergo a decomposition reaction due to the increase in the temperature of the stirring shaft, resulting in degradation of the polymer matrix and decomposition and failure of the flame retardant; 2. Due to the high temperature of the stirring shaft, thermal deformation may occur, which will destroy its dynamic balance state. At the same time, the cable material adheres to the outside of the stirring shaft, causing its rotation center to shift. During the rotation process, the unbalanced stirring shaft will cause equipment vibration. Although the initial vibration amplitude may be small, it will accumulate over a long period of time and gradually loosen the various connecting components of the equipment, affecting the stability and service life of the equipment.

[0005] Therefore, a heat-insulating and flame-retardant high-voltage cable material processing device is needed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the prior art. The present invention proposes a heat-insulating and flame-retardant high-voltage cable material processing device to solve the problem raised in the above-mentioned prior art that the cable material has high viscosity and is easily adhered to the outside of the stirring shaft during the rotation of the stirring shaft.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: a heat-insulating flame-retardant high-voltage cable material processing device, comprising a mixing barrel, a fixed cover is fixedly installed on the upper end of the mixing barrel, a drive motor is fixedly installed on the upper end of the fixed cover, model Shinano 103H7123-5040, the outer side of the fixed cover is fixed by multiple sets of locking buckles, a connecting disk is rotatably installed inside the fixed cover, a gear ring is fixedly installed on the inner side of the connecting disk, a large gear is provided in the center of the gear ring, a small gear is meshed with the outer side of the large gear, the small gear is meshed with the gear ring, the upper end of the large gear is fixedly connected to the drive motor, the lower end of the large gear is fixedly installed with a stirring shaft, the outer side of the stirring shaft is rotatably provided with multiple sets of conical rods, the upper end of the stirring shaft passes through the connecting disk, the lower end of the small gear is fixedly installed with a scraper assembly, the stirring mechanism of the scraper assembly and the conical rods are staggered, and the scraper assembly fits against the inner wall of the mixing barrel.

[0008] Furthermore, the mixing barrel includes a barrel shell, a plurality of support legs are fixedly installed on the lower end of the barrel shell, a feed port is provided on the outside of the barrel shell, at least one group of scraper assemblies are provided inside the barrel shell, the upper end of the scraper assembly is connected to the pinion, the lower end of the scraper assembly passes through the barrel shell and is fixedly installed with a feeding assembly, a circular hole is provided at the lower end of the barrel shell, the circular hole matches the central axis of the scraper assembly, and a discharge port is provided at the lower end of the barrel shell.

[0009] Furthermore, the scraper assembly includes a central shaft, and multiple groups of scraper extrusion mechanisms are fixedly installed on the outer side of the central shaft. A feeding assembly is fixedly installed on the lower end of the central shaft. The scraper extrusion mechanism fits the inner wall of the barrel shell. When the raw materials of the cable material need to be mixed, the various raw materials are introduced into the interior of the barrel shell through the feed port, and the driving motor is started to drive the large gear to rotate, and at the same time, the small gear is driven to rotate along the gear ring, thereby driving the stirring shaft and the tapered rod on its outer side to rotate. At the same time, the scraper extrusion mechanism at the upper end of the scraper assembly is rotated inside the barrel shell. The raw materials are stirred and mixed, and discharged through the discharge port after stirring. Since cable materials usually have high viscosity and are sensitive to temperature, excessively high temperature may cause degradation of the polymer matrix and decomposition of the flame retardant, which makes the material fluidity worse during stirring. At the same time, the viscous material is easy to adhere to the outer side of the tapered rod and the scraper extrusion mechanism and the inner wall of the barrel shell, causing local overheating on the scraper extrusion mechanism due to the adhesion of the cable material, decomposing the components of the cable material, and the cable material is very easy to adhere to the tapered rod outside the stirring shaft. Due to the adhesion position and thickness The degree is often difficult to be uniform, which will break the original mass balance of the tapered rod, the stirring shaft and the scraper assembly, causing the center of gravity to deviate to the side with more cable material during rotation, resulting in the deviation of the rotation center, which will gradually loosen the various connecting parts of the equipment and affect the stability and service life of the equipment. During the stirring and mixing process, the scraper extrusion mechanism continuously squeezes the inner wall of the barrel shell, and then gradually squeezes the silicone oil inside the feeding assembly into the interior of the scraper extrusion mechanism and flows out from both sides of the scraper extrusion mechanism, and is fully mixed with the raw materials during stirring. At the same time, during the stirring process, the low surface tension of the silicone oil enables it to quickly spread on the surface of the scraper extrusion mechanism to form a lubricating film, thereby improving the lubrication of the outside of the scraper extrusion mechanism, so that the raw materials will not adhere to the outside of the scraper extrusion mechanism. At the same time, the outer wall of the scraper extrusion mechanism is cooled by the silicone oil, reducing the problem of local overheating caused by the adhesion of the cable material and decomposition of the components of the cable material. At the same time, the scraper extrusion mechanism continuously scrapes off the cable material adhering to the outside of the tapered rod, reducing the center of gravity deviation during rotation, improving the stirring efficiency of the device while reducing structural damage to the device.

[0010] Furthermore, two groups of feed pipes are provided inside the central shaft, and two groups of feed troughs are provided outside the central shaft. Feed trough one matches the feed pipe, and feed trough one is connected to the scraper extrusion mechanism. An exhaust pipe is provided between the two groups of feed pipes, and an exhaust groove is provided outside the central shaft. The exhaust groove matches the exhaust pipe, and the exhaust groove is connected to the scraper extrusion mechanism.

[0011] Furthermore, the scraper extrusion mechanism includes a connecting shell, the interior of the connecting shell is divided into three parts, namely a central groove and discharge grooves on both sides, a feed groove 2 is provided at one end of the discharge groove close to the central axis, the feed groove 2 matches the conveying pipe, and the central groove matches the exhaust groove, an extrusion rod is slidably provided at one end of the connecting shell, the extrusion rod matches the central groove, and limit rods are fixedly installed on the upper and lower sides of the extrusion rod, an elastic part 1 is provided on the outside of the limit rod, and limit grooves are provided at the upper and lower ends of the inner wall of the connecting shell, the limit grooves match the limit rods, one end of the elastic part 1 is fixed on the limit rod, and the other end of the elastic part 1 is fixed on the inner wall of the limit groove, and two groups of extrusion disks are slidably provided inside the connecting shell, and the sides of the two groups of extrusion disks away from each other are slidably connected to the connecting shell through the elastic part 2. The two sets of extrusion discs are connected, and the side away from each other passes through the center groove of the connecting shell and is fixedly installed with an extrusion plate, which is located inside the feed trough 2. Multiple sets of elastic members 3 are provided on the side of the extrusion plate close to the extrusion disc, and one end of the elastic member 3 is fixedly connected to the inner wall of the feed trough 2. Multiple sets of discharge columns are fixedly installed on the side of the extrusion plate away from the extrusion disc, and multiple holes are provided on the outside of the discharge columns. The discharge columns pass through one side of the connecting shell and are slidably connected thereto. In the initial state, the holes and grooves of the discharge columns are located inside the discharge trough. When the driving motor drives the central shaft to rotate, and then drives the scraper extrusion mechanism to mix and stir the raw materials inside the barrel shell, in the initial state, the extrusion rods inside the multiple sets of scraper extrusion mechanisms outside the central shaft do not contact the inner wall of the barrel shell. At this time, the silicon The oil is stored inside the feeding assembly and will not be discharged with the rotation of the scraper extrusion mechanism. When the scraper extrusion mechanism rotates, a part of the scraper extrusion mechanism first contacts the inner wall of the barrel shell and is squeezed. The extrusion rod inside the scraper extrusion mechanism is squeezed by the barrel shell, shrinks into the inside of the connecting shell, and gradually squeezes the internal air of the center groove. In the process of the extrusion rod being squeezed, it slides inside the connecting shell through the limit rod and the elastic member. When the extrusion rod is squeezed to the center position of the center groove, the two groups of extrusion disks inside the center groove are squeezed by the extrusion rod. At this time, the extrusion disk expands outward, and the extrusion plate is driven to move inside the discharge trough by the extrusion disk, and the discharge column on one side of the extrusion plate is pushed out of the inside of the connecting shell, and the outside of the discharge column is pushed out of the connecting shell. The hole groove is exposed, and at the same time, when the extrusion rod squeezes the internal air of the center groove, the air is discharged into the exhaust pipe through one end of the center groove. At this time, the air flows into the interior of the feeding barrel through the intake pipe and squeezes the two sets of piston discs. The silicone oil between the two sets of piston discs and the feeding barrel is sent into the interior of the feeding pipe through the feeding pipe, and flows into the interior of the discharge trough through the second feeding groove, and flows out along the hole groove on the outside of the discharge column. When the silicone oil flows out, it not only improves the lubrication of the outer surface of the connecting shell, but also reduces the surface temperature of the connecting shell and reduces the decomposition of the raw materials. At the same time, by pouring the silicone oil into the mixed raw materials from the inner wall position close to the outer shell of the barrel body, the silicone oil poured close to the inner wall can directly act on the sticky wall area, quickly reduce the friction between the material and the barrel wall of the barrel body outer shell, and reduce sticky accumulation.In order to avoid local overheating, compared with the central axis area, the material fluidity near the inner wall is worse and the friction is more intense. Prioritizing lubrication here can improve the overall stirring resistance and enhance the stirring efficiency. Moreover, the silicone oil is introduced from the inner wall position close to the barrel shell, and can be quickly brought into the central area through shear force and convection to mix with the material. While the extrusion rod is squeezing the inner wall of the barrel shell, the inner wall of the barrel shell is scraped off the raw materials to prevent the inner wall of the barrel shell from absorbing too much raw materials, resulting in a decrease in the mixing efficiency. At the same time, the other part of the scraping extrusion mechanism does not contact the inner wall of the barrel shell, and only performs stirring and mixing operations. When the extrusion rod is no longer in contact with the inner wall of the barrel shell, the material is scraped off the inner wall of the barrel shell to prevent the inner wall of the barrel shell from absorbing too much raw materials, which will reduce the mixing efficiency. Under the action of the second elastic member, the third elastic member, and the discharge chute, the discharge column is reset to the inside of the connecting shell, and the extrusion rod is also reset. As the extrusion rod resets, it preferentially draws outside air through the one-way valve to replenish the air inside the center groove and the two sets of piston discs. At this time, the multiple sets of scraper extrusion mechanisms do not contact the inner wall of the barrel shell, but only stir and mix with the raw materials. By intermittently extruding the silicone oil, it allows time to fully diffuse and penetrate the cable material. After a certain amount of silicone oil is extruded, the silicone oil gradually disperses among the materials under the stirring action, forming a uniform lubricating film, effectively reducing the friction between the molecules within the material, improving the fluidity of the cable material, and enhancing the mixing uniformity.

[0012] Furthermore, the feeding assembly includes a connecting block, a feeding barrel is fixedly installed on the lower end of the connecting block, two groups of feed valves are provided at both ends of the feeding barrel, two groups of feeding pipes are opened through both ends of the feeding barrel, the feeding pipes are connected with the conveying pipe, an air intake pipe is opened through the outside of the feeding barrel, the air intake pipe is connected with the exhaust pipe, two groups of piston disks are provided inside the feeding barrel, the two groups of piston disks are connected with the air intake pipe, a one-way valve is provided at the lower end of the feeding barrel, and the air inlet of the one-way valve is located between the two groups of piston disks.

[0013] Furthermore, a conical shell is fixedly installed on the upper end of the connecting shell, and a slide groove is opened inside the conical shell. Multiple groups of elastic parts four are fixedly installed inside the slide groove, and a conical scraper block is fixedly installed on the upper end of the elastic part four. When the stirring shaft and the scraper assembly rotate, the conical shell at the upper end of the connecting shell and the conical scraper block inside it rotate on the stirring shaft, and the raw materials adhering to the conical rod rotating on the outside of the stirring shaft are scraped off. When the conical rod contacts the conical scraper block, the conical scraper block is squeezed and compressed by the conical rod. When the two are separated, the conical scraper block moves upward under the action of the elastic part four, and scrapes one side of the conical rod. The conical rod continuously rotates, and the raw materials adhering to the outside of the conical rod are cleaned, thereby preventing the raw materials adhering to the outside of the conical rod, reducing the center of gravity deviation of the stirring shaft during rotation, and improving the stirring efficiency of the device while reducing structural damage to the device.

[0014] Compared with the prior art, the beneficial effects of the present application include: the scheme can quickly act on the easy-to-stick barrel wall area by adding silicone oil from the position close to the inner wall of the stirring barrel during stirring, reduce the friction between the material and the barrel wall and the scraping mechanism, reduce the risk of local overheating and polymer degradation, and at the same time, the lubricant is uniformly dispersed to the central area by the stirring motion, improving the mixing efficiency; in combination with the planetary gear multi-shaft stirring structure, the coordinated motion of multiple stirring rods and scraping mechanisms can further enhance the stirring uniformity and scraping effect, prevent the center of gravity from deviating and the equipment from vibrating due to uneven adhesion of the material to the stirring shaft, and the intermittent extrusion of the lubricating liquid can accurately control the amount, avoid waste and pollution, and the low-temperature lubricating liquid reduces the temperature of the scraping mechanism, finally realizing high-quality mixing of the cable material and improving the stability and service life of the equipment.

[0018] In order to further understand the present application, the present application is described in detail in combination with the accompanying drawings.

[0019] According to an embodiment of the present application in combination with Figure 1-3The invention shows a heat-insulating flame-retardant high-voltage cable material processing device, comprising a mixing barrel 1, a fixed cover 2 is fixedly installed on the upper end of the mixing barrel 1, a driving motor 21 is fixedly installed on the upper end of the fixed cover 2, and the model is Shinano 103H7123-5040. The outer side of the fixed cover 2 is fixed by multiple sets of locking buckles 22. A connecting disk 23 is rotatably installed inside the fixed cover 2, and a gear ring 231 is fixedly installed on the inner side of the connecting disk 23. A large gear 232 is provided at the center of the gear ring 231, and the outer side of the large gear 232 is meshed with the outer side of the large gear 232. A small gear 233 is provided, which meshes with the gear ring 231. The upper end of the large gear 232 is fixedly connected to the drive motor 21. The lower end of the large gear 232 is fixedly installed with a stirring shaft 13. The outer side of the stirring shaft 13 is rotatably provided with multiple groups of tapered rods 131. The upper end of the stirring shaft 13 passes through the connecting disk 23. The lower end of the small gear 233 is fixedly installed with a scraper assembly 14. The stirring mechanism of the scraper assembly 14 and the tapered rods 131 are staggered with each other, and the scraper assembly 14 fits against the inner wall of the mixing barrel 1.

[0020] According to one embodiment of the present invention, Figure 3-4 As shown, the mixing barrel 1 includes a barrel shell 11, and a plurality of support legs 12 are fixedly installed at the lower end of the barrel shell 11. A feed port 111 is provided on the outside of the barrel shell 11, and at least one group of scraper assemblies 14 are provided inside the barrel shell 11. The upper end of the scraper assembly 14 is connected to the pinion 233, and the lower end of the scraper assembly 14 passes through the barrel shell 11 and is fixedly installed with a feeding assembly 15. A circular hole 16 is provided at the lower end of the barrel shell 11, and the circular hole 16 matches the central axis 141 of the scraper assembly 14. A discharge port 17 is provided at the lower end of the barrel shell 11.

[0021] According to one embodiment of the present invention, Figure 3-4As shown, the scraper assembly 14 includes a central shaft 141, and multiple groups of scraper extrusion mechanisms 142 are fixedly installed on the outer side of the central shaft 141. The lower end of the central shaft 141 is fixedly installed with a feeding assembly 15. The scraper extrusion mechanism 142 is in contact with the inner wall of the barrel shell 11. When the raw materials of the cable material need to be mixed, the various raw materials are introduced into the interior of the barrel shell 11 through the feed port 111, and the driving motor 21 is started to drive the large gear 232 to rotate, and the small gear 233 is driven to rotate along the gear ring 231, thereby driving the stirring shaft 13 and the tapered rod 131 on its outer side to rotate. At the same time, the scraper assembly 14 The scraper extrusion mechanism 142 at the upper end stirs and mixes the raw materials inside the barrel shell 11, and discharges them through the discharge port 17 after stirring. Since the cable material usually has high viscosity and is sensitive to temperature, excessively high temperature may cause degradation of the polymer matrix and decomposition of the flame retardant, which makes the fluidity of the material worse during stirring. At the same time, the viscous material is easy to adhere to the outer side of the tapered rod 131 and the scraper extrusion mechanism 142 and the inner wall of the barrel shell 11, causing the scraper extrusion mechanism 142 to be locally overheated due to the adhesion of the cable material, decomposing the components of the cable material, and the cable material is very easy to adhere to the tapered rod 131 on the outer side of the stirring shaft 13. On the rod 131, since the adhesion position and thickness are often difficult to be uniform, this will break the original mass balance state of the tapered rod 131, the stirring shaft 13 and the scraper assembly 14, resulting in the center of gravity being biased towards the side with more cable material during rotation, causing the rotation center to shift, which will gradually loosen the various connecting parts of the equipment, affecting the stability and service life of the equipment. During the stirring and mixing process, the device continuously squeezes the inner wall of the barrel shell 11 through the scraper extrusion mechanism 142, and then gradually squeezes the silicone oil inside the feeding assembly 15 into the interior of the scraper extrusion mechanism 142, and flows out from both sides of the scraper extrusion mechanism 142, mixing with the raw materials during stirring. During stirring, the silicone oil is fully mixed. At the same time, during the stirring process, the low surface tension of the silicone oil enables it to quickly spread on the surface of the scraper extrusion mechanism 142 to form a lubricating film, thereby improving the lubrication of the outside of the scraper extrusion mechanism 142, so that the raw materials will not adhere to the outside of the scraper extrusion mechanism 142. At the same time, the outer wall of the scraper extrusion mechanism 142 is cooled by the silicone oil, reducing the problem of local overheating caused by the adhesion of the cable material and decomposition of the components of the cable material. At the same time, the scraper extrusion mechanism 142 continuously scrapes off the cable material adhering to the outside of the tapered rod 131, reducing the center of gravity deviation during rotation, improving the stirring efficiency of the device, and reducing structural damage to the device.

[0022] According to one embodiment of the present invention, Figure 4-5It is shown that two groups of feed pipes 1411 are opened inside the central shaft 141, and two groups of feed troughs 1413 are opened on the outside of the central shaft 141.

At the same time, when the squeezing rod 144 squeezes the internal air of the central groove 1423, the air is discharged into the interior of the exhaust pipe 1412 through one end of the central groove 1423. At this time, the air flows into the interior of the feeding barrel 152 through the air inlet pipe 154 and squeezes the two sets of piston discs 155. The silicone oil between the two sets of piston discs 155 and the feeding barrel 152 is fed into the interior of the delivery pipe 1411 through the feeding pipe 153 and passes through the feeding trough 142 4 flows into the interior of the discharge trough 1422 and flows out along the hole groove on the outside of the discharge column 1429. When the silicone oil flows out, it not only improves the lubrication of the outer surface of the connecting shell 1421, but also reduces the surface temperature of the connecting shell 1421, reducing the decomposition of the raw materials. At the same time, by pouring the silicone oil into the mixed raw materials from the inner wall position close to the barrel shell 11, the silicone oil poured close to the inner wall can directly act on the sticky wall area, quickly reducing the friction between the material and the barrel wall of the barrel shell 11, reducing sticky accumulation, avoiding local overheating, and at the same time, compared with the central axis area, the material near the inner wall has worse fluidity and more intense friction. Prioritizing lubrication here can improve the overall stirring resistance and improve the stirring efficiency. The silicone oil is introduced from the inner wall position close to the barrel shell 11, and can be quickly brought into the central area through shear force and convection to mix with the material. When the extrusion rod 144 squeezes the inner wall of the barrel shell 11, the inner wall of the barrel shell 11 is scraped off the raw materials to prevent the inner wall of the barrel shell 11 from absorbing too much raw materials, resulting in a decrease in mixing efficiency. At the same time, the other part of the scraping extrusion mechanism 142 does not contact the inner wall of the barrel shell 11, and only performs stirring and mixing operations. When the extrusion rod 144 does not contact the inner wall of the barrel shell 11, the discharge column 1429 is reset under the action of the elastic member 2 1427, the elastic member 3 1428, and the discharge trough 1422. To the interior of the connecting shell 1421, the extrusion rod 144 also resets. While resetting, the extrusion rod 144 preferentially draws in external air through the one-way valve 156 to replenish the air inside the central groove 1423 and the two sets of piston discs 155. At this time, the multiple sets of scraper extrusion mechanisms 142 do not contact the inner wall of the barrel shell 11, but only perform a stirring and mixing operation with the raw materials. By intermittently extruding the silicone oil, the silicone oil has time to fully diffuse and penetrate into the cable material. After a certain amount of silicone oil is extruded, the silicone oil gradually disperses among the materials under the stirring action, forming a uniform lubricating film, effectively reducing the friction between the molecules within the material, improving the fluidity of the cable material, and enhancing the mixing uniformity.

[0024] According to one embodiment of the present invention, Figure 1-3 、 Figure 11-12It is shown that the feeding assembly 15 includes a connecting block 151, and a feeding barrel 152 is fixedly installed at the lower end of the connecting block 151. Two groups of feed valves 1521 are provided at both ends of the feeding barrel 152. Two groups of feeding pipes 153 are provided at both ends of the feeding barrel 152, and the feeding pipes 153 are connected with the conveying pipe 1411. An air intake pipe 154 is provided at the outside of the feeding barrel 152, and the air intake pipe 154 is connected with the exhaust pipe 1412. Two groups of piston disks 155 are provided inside the feeding barrel 152, and the two groups of piston disks 155 are connected with the air intake pipe 154. A one-way valve 156 is provided at the lower end of the feeding barrel 152, and the air inlet of the one-way valve 156 is located between the two groups of piston disks 155.

[0025] According to one embodiment of the present invention, Figure 4-10 As shown, a conical shell 143 is fixedly installed on the upper end of the connecting shell 1421, a chute 1431 is opened inside the conical shell 143, and multiple sets of elastic members 1433 are fixedly installed inside the chute 1431. A conical scraper block 1432 is fixedly installed on the upper end of the elastic member 1433. When the stirring shaft 13 and the scraper assembly 14 rotate, the conical shell 143 at the upper end of the connecting shell 1421 and the conical scraper block 1432 inside it rotate on the stirring shaft 13, scraping the raw material from the tapered rod 131 rotating on the outside of the stirring shaft 13. In addition, when the conical rod 131 contacts the conical scraper block 1432, the conical scraper block 1432 is squeezed and compressed by the conical rod 131. When the two are separated, the conical scraper block 1432 moves upward under the action of the elastic member 1433, and scrapes one side of the conical rod 131. The conical rod 131 continuously rotates, thereby completing the cleaning of the raw materials adhering to the outside of the conical rod 131, preventing the raw materials from adhering to the outside of the conical rod 131, reducing the deviation of the center of gravity of the stirring shaft 13 during rotation, and improving the stirring efficiency of the device while reducing structural damage to the device.
