Description

Technical Field

[0001] The present invention belongs to the technical field of fiber production, and particularly relates to a high-precision spinning finish preparation device and method. Background Art

[0002] During the spinning process, the fiber has a large friction with the equipment components, which is prone to breakage and fuzzing, affecting production efficiency and fiber quality. A suitable spinning finish can reduce friction, reduce static electricity generation, and prevent fibers from winding around each other. Therefore, it is usually necessary to mix different raw material ratios through a spinning finish preparation device, which can endow the fiber with smooth characteristics, reduce the friction between the fiber and the equipment components during the spinning process, and reduce the damage to the fiber caused by the heat generated by friction, ensuring the integrity of the fiber.

[0003] During the preparation of the spinning finish, extremely high precision is required for temperature control. This is mainly because temperature has a very significant impact on the viscosity of the finish. For example, for vegetable oil and water, when the temperature rises by 10°C, the viscosity of vegetable oil will decrease by 30 - 50%, and the viscosity of water will decrease by 20 - 30%. Therefore, too high a temperature will cause the viscosity of the finish to be too low to effectively adhere to the fiber surface and cannot play a good role in reducing friction and lubricating the fiber surface. However, if the temperature of the finish is too low, it will cause the viscosity of the finish to be too high and the fluidity to become poor, making it difficult to form a uniform film on the fiber surface. Experiments show that for some existing finishes, a temperature fluctuation of ±5°C may cause the viscosity to change by more than 20%. Therefore, during the preparation of the existing spinning finish, the prepared finish often needs to be placed in a constant-temperature storage tank and left to stand to ensure uniform temperature before being transported to the spinning machine.

[0004] In addition, during the preparation of the spinning finish, extremely high requirements are also placed on the uniformity of the finish temperature between regions. This is mainly because most of the existing spinning finishes are emulsion systems, such as mineral oil / water emulsions. If the local temperature is too high during the preparation of the spinning finish, it will reduce the adsorption capacity of the emulsifier at the oil-water interface, resulting in a weakened emulsification film strength and easy coalescence of oil droplets. This uneven temperature between regions of the finish will cause a large change in the emulsion particle size, ultimately leading to a wider distribution of the emulsion particle size, resulting in a decline in the stability, oiling effect, and uniformity of the oil film thickness of the finish. At the same time, it will also lead to an increase in the number of fuzz and breaks during the spinning process. Experiments show that when the emulsion temperature rises from 25°C to 30°C, the emulsion particle size increases from 0.5μm to 2μm, and the oiling rate of the fiber decreases by 13%. More seriously, when the uneven distribution of the emulsion particle size deteriorates to a certain extent, it will destroy the balance between the emulsifier and the oil-water interface, resulting in demulsification and stratification of the finish. This is the reason why in the existing technology, sometimes after the spinning finish is prepared, it is necessary to filter the emulsion, remove large-sized oil droplets, or narrow the particle size distribution through high-pressure homogenization.

[0005] To improve the temperature control accuracy and temperature uniformity among regions during the preparation of spinning finish, the prior art mostly uses heat transfer oil to heat the spinning finish in order to achieve precise control of the finish temperature. For example, a Chinese patent with the application number 201922131233.6 discloses a jacketed oil bath heating type stirring reactor, which includes a reactor body. A jacket is fixedly connected to the surface of the reactor body. A feed hopper is communicated with one side of the jacket. There is soybean oil arranged between the side of the jacket opposite to the reactor body. An electric heater is used to heat the soybean oil at the bottom of the reactor body. This kind of reactor mainly relies on heat conduction and natural convection to transfer heat. And natural convection is based on the density difference generated by the temperature difference of the liquid to drive the liquid flow. Therefore, the natural convection of the soybean oil in the jacket is relatively slow. Moreover, there is a certain space between the jacket and the reactor body. The flow state of the soybean oil in the jacket will affect the heat transfer efficiency. Specifically, the flow of the soybean oil in the jacket is uneven. The soybean oil in some areas may not be able to obtain sufficient heat in time, or the path for the heat to transfer to the reactor body is long, which will also lead to a slow heating speed. Secondly, after the reaction ends, the soybean oil can only be cooled by natural heat dissipation, and the heat exchange speed with the external environment is slow, resulting in low cooling efficiency.

[0006] In this kind of bushing type reactor, convective mixing depends on the macroscopic motion of the fluid, while diffusive mixing depends on molecular motion. The narrow space limits the convective intensity, and at the same time, the molecular diffusion path is long, resulting in both mixing mechanisms being difficult to play an efficient role. At the same time, the narrow channel of the annular space also restricts the free flow path of the liquid, resulting in the fluid being prone to flow separation and secondary flow at the bend, forming a local stagnant area, resulting in the flow of the liquid in the annular space mainly along the tangential direction, with weak radial mixing effect. At low flow rates, the flow of the liquid in the annular space is mainly laminar, with a single flow direction and slow molecular diffusion, resulting in low mixing efficiency. Even when turbulence is formed at high flow rates, the scale of the turbulent vortices will be limited and cannot effectively cover the entire annular space, resulting in uneven mixing. At the same time, the curvature will also cause the action of centrifugal force, forming a velocity gradient of the liquid in the radial direction, further hindering uniform mixing. Therefore, in this kind of reactor, the flow and mixing between the liquid heat transfer oils in different regions are very difficult, ultimately resulting in poor temperature control accuracy and temperature uniformity among regions in the reactor.

[0007] Therefore, researching and developing a high-precision spinning finish configuration device and method is of great significance for improving the quality and efficiency of fiber production. Summary of the Invention

[0015] On one side of the top of the support seat, a lifting rod slidably connected to the moving seat is installed. On the top of the lifting rod, an L-shaped seat is installed. On the other side of the top of the support seat, a lifting screw wheel threadedly connected to the moving seat is rotatably connected. The top of the lifting screw wheel rotatably passes through the horizontal end of the L-shaped seat and then a turntable is installed.

[0017] Furthermore, This application also discloses a method for preparing a high-precision spinning oil agent, which uses the above-mentioned high-precision spinning oil agent preparation device, and the specific steps are as follows: The jacket is installed on the outer side of the kettle body, and heat-conducting oil is introduced to regulate the temperature. The temperature sensor in the kettle body monitors the temperature of the spinning finish in real time. The motor is installed on the side opposite to the kettle body, and drives the driving roller to rotate through the driving wheel and the connecting belt, and then the stirring rod stirs the spinning finish in the kettle body; Connect the inlet oil pipe to the oil transfer pump, inject heat-conducting oil into the jacket and then close the control valve to form a closed space. Start the heating plate. The driving component drives the rotating plate to rotate around the fixed disk. The rotating plate stirs the heat-conducting oil to form forced convection, accelerating the flow and mixing of the heat-conducting oil, and enabling it to be heated quickly and evenly; The rotating plate is spiral-shaped. When it rotates, it forms a spiral flow field. Under its action, the heat-conducting oil spirally rises and circulates to heat the substances in the kettle body; The heating plate is spiral-shaped, with a length of one-third of the spiral line of the rotating plate. Three heating plates are spaced apart at the bottom, middle, and top of the rotating plate to heat the heat-conducting oil in multiple layers. The jet holes of the rotating plate increase the flow rate of the outflowing heat-conducting oil, enhancing the heat exchange with the kettle body and disturbing the surrounding heat-conducting oil to ensure uniform temperature; The external circulation pump drives the coolant to enter the kettle cover through the cooling pipe, flows through the cooling tank to the rotary joint, and enters the spiral cooling holes inside the rotating plate. The coolant exchanges heat with the rotating plate in the cooling holes, absorbs the heat of the heat-conducting oil, realizes indirect cooling. The coolant after heat exchange flows into the rotating collection seat, and is discharged from the drain pipe through the drain hole, the fixed disk collection hole, and the drain tank to complete the cycle; The driving component drives the rotating plate to rotate, and the coolant sprays out from the cooling holes of multiple rotating plates and is evenly distributed in the jacket space, increasing the heat exchange area with the heat-conducting oil. The rotation of the rotating collection seat ensures smooth discharge of the coolant.

[0018] Compared with the prior art, the high-precision spinning finish configuration method described in the present invention has the following advantages: 1. In the present invention, through the rotating heat-conducting component, the rotation of the rotating plate promotes the formation of forced convection of the heat-conducting oil, significantly accelerating the flow rate and mixing degree of the heat-conducting oil. Compared with natural convection, the heat-conducting oil can contact the heating plate and absorb heat faster, reducing the heat transfer path and time, greatly improving the heating speed of the heat-conducting oil in the entire jacket, and improving production efficiency. Moreover, the rotating plate is of a spiral structure, and when it rotates, it forms a unique spiral flow field, enhancing the stirring and mixing ability of the heat-conducting oil, making the heat-conducting oil spiral upward and circulate around the periphery of the kettle body to uniformly heat the substances in the kettle body. The heating plate is also spiral-shaped and is reasonably distributed at different height positions of the rotating plate, and can heat the heat-conducting oil in all directions and at multiple levels simultaneously from multiple layers to ensure that the temperatures of all parts of the kettle body are consistent. The jet hole design increases the flow rate of the heat-conducting oil when it flows out, enhancing the heat exchange with the kettle body and disturbing the surrounding heat-conducting oil, further optimizing the temperature uniformity.

[0019] 2. The present invention utilizes an axial flow cooling assembly to drive the circulation of the coolant by means of an external circulation pump. The coolant enters the spiral cooling holes inside the rotating plate through the cooling pipes and the cooling tank, and undergoes sufficient heat exchange with the rotating plate to absorb the heat of the heat transfer oil, thereby achieving indirect cooling. The spiral arrangement of the cooling holes prolongs the contact time between the coolant and the rotating plate, improving the cooling efficiency. The driving assembly drives the rotation of the rotating plate, causing the coolant to be ejected from the cooling holes of multiple rotating plates and evenly distributed in the jacket space, increasing the heat exchange area with the heat transfer oil. At the same time, the rotation of the rotating collection seat ensures smooth discharge of the coolant, preventing the accumulation of the coolant, achieving rapid and uniform cooling of the heat transfer oil, ensuring temperature consistency during the preparation process of the spinning oil agent, and improving the product quality.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0022] See also Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, the present invention provides a high-precision spinning oil configuration device and method, a high-precision spinning oil configuration device, comprising a support seat 1, a kettle body 12 arranged on one side of the support seat 1 and a kettle cover 13 arranged on the top of the kettle body 12, the kettle cover 13 is used to close the kettle body 12, to prevent external impurities from mixing in and internal substances from leaking, to ensure the purity of the spinning oil configuration environment, the kettle body 12 can rotate inside the support seat 1, and provides a structural basis for subsequent cleaning operations; a jacket 121, which is installed on the outside of the kettle body 12, by passing heat transfer oil into the jacket 121, the spinning oil in the kettle body 12 can be accurately controlled in temperature, to meet the strict temperature requirements at different stages in the oil configuration process, a temperature sensor is installed in the kettle body 12, for real-time detection of the temperature of the spinning oil; a connecting tube 14, one end of its top is fixedly installed on the top of the kettle cover 13, and one end of its bottom passes through the kettle body 12 The inner side plays a certain sealing and protective role to prevent the oil agent in the kettle body 12 from leaking; the movable seat 15 is arranged on the top of the support seat 1; the driving roller 16 is rotatably connected to the top of the connecting tube 14, and the side of the movable seat 15 facing away from the kettle body 12 is equipped with a motor through a motor seat, and a driving wheel is installed at the output end of the motor. The driving wheel and the outer side of the driving roller 16 are connected by a connecting belt for transmission. The stirring rod 17 is installed at the bottom of the driving roller 16 and passes through the inner side of the kettle body 12. When the motor starts to run, the driving wheel at the output end of the motor rotates accordingly, and with the help of the transmission effect of the connecting belt, the driving roller 16 is driven to rotate synchronously, thereby providing a power source for the rotation of the stirring rod 17. When the driving roller 16 rotates, the stirring rod 17 rotates in the kettle body 12 accordingly, and the various components of the spinning oil agent in the kettle body 12 are stirred and mixed, so as to achieve a uniform mixing effect of the spinning oil agent, thereby meeting the requirements of high-precision configuration.

[0023] See also Figures 1 - 4As shown, the rotating heat-conducting component 2 is arranged between the kettle body 12 and the jacket 121 and is used to form a spiral flow field by rotation to quickly and evenly heat the heat-conducting oil in the jacket 121. The rotating heat-conducting component 2 includes a fixed disk 21 fixedly installed on the bottom wall of the kettle body 12; at least six rotating plates 22, the cross section of which is in a plate-like structure; at least three heating plates 23 arranged on one side of the rotating plates 22; a sealing cover 24 installed on the top of the jacket 121, with an opening in the middle facing downward; an oil inlet pipe 25 fixedly connected to an external oil pump, one end of which is installed on one side of the top of the jacket 121; an oil drain pipe 26, one end of which is installed on one side of the bottom of the jacket 121, and control valves are installed on the oil inlet pipe 25 and the oil drain pipe 26; a driving component 211 arranged on the sealing cover 24 and used to drive the rotating plates 22 to rotate.

[0024] It should be noted that first, connect the oil inlet pipe 25 to an external oil pump. After starting the oil pump, the heat-conducting oil is transported into the jacket 121 through the oil inlet pipe 25. When an appropriate amount of heat-conducting oil is filled in the jacket 121, close the control valves on the oil inlet pipe 25 and the oil drain pipe 26 to make the jacket 121 form a relatively closed space for containing the heat-conducting oil. The external control system issues an instruction to heat the heating plates 23. The heating plates 23 start to emit heat and become the heat source for heating the heat-conducting oil in the jacket 121. With the cooperation of the driving component 211, it generates a driving force to drive the rotating plates 22 to rotate around the fixed disk 21 inside the jacket 121. Since the cross section of the rotating plates 22 is in a plate-like structure, during the rotation process, it will stir and push the heat-conducting oil in the jacket 121. The rotation of the rotating plates 22 makes the heat-conducting oil flow around the kettle body 12. During the flowing process, the heat-conducting oil continuously contacts the heating plates 23 and absorbs the heat emitted by them. At the same time, due to the stirring effect of the rotating plates 22, forced convection is formed in the jacket 121 for the heat-conducting oil. Compared with natural convection, the flow rate and mixing degree of the heat-conducting oil are greatly increased, which enables the heat-conducting oil to be heated more quickly and evenly, and avoids the problem that the heat-conducting oil in some areas cannot obtain sufficient heat in time due to poor flow. It is worth noting that the material of the rotating plates 22 has certain heat-conducting ability. The preferred material is stainless steel, which can quickly transfer the heat of the heating plates 23 to the surrounding heat-conducting oil during the rotation process, helping to improve the heating speed and uniformity of the heat-conducting oil.

[0025] It is worth noting that when the temperature feedback by the temperature sensor is lower than the set target temperature, the control system will increase the heating power of the heating plates 23 according to the difference between the current temperature and the target temperature and in accordance with the preset control algorithm. In the present invention, by providing a rotating heat-conducting component 2, specifically, the rotation of the rotating plate 22 prompts the heat-conducting oil to form forced convection, greatly improving the flow rate of the heat-conducting oil. Compared with natural convection, the heat-conducting oil can contact the heating plate 23 and absorb heat more quickly, reducing the path and time for heat to be transferred to the kettle body 12, thereby significantly accelerating the heating rate of the heat-conducting oil in the entire jacket 121, improving production efficiency, making the heat-conducting oil mix more evenly in the jacket 121, and ensuring that the heat-conducting oil in each area can obtain sufficient heat in a timely manner.

[0026] See Figures 4 - 6 As shown, the overall shape of the rotating plate 22 is a spiral structure, and the rotation direction of the rotating plate 22 is opposite to the direction of its spiral upward, so that a spiral upward flow field can be formed through the rotation of the rotating plate 22.

[0027] It should be noted that, please refer to the specification Figure 4 (the indication line refers to the rotation direction of the rotating plate 22) and refer to the specification Figure 5 (the indication line refers to the flow direction of the heat-conducting oil). By setting the spiral structure, during the rotation process, the heat-conducting oil can form a unique spiral flow field. This spiral flow field can make the heat-conducting oil form a stronger and more complex flow pattern in the jacket 121, greatly enhancing the stirring and mixing ability of the heat-conducting oil, so that the heat-conducting oil can be heated more evenly, improving the uniformity and efficiency of heating; Specifically, please refer to the specification Figure 6 (the indication line refers to the direction in which the heat-conducting oil rushes towards the kettle body 12). When the heat-conducting oil contacts the rotating plate 22, heat conduction occurs, and the heat-conducting oil absorbs the heat on the rotating plate 22. At the same time, under the action of the spiral tangential force generated by the rotation of the rotating plate 22, the heat-conducting oil is pushed to move in a spiral upward motion around the periphery of the kettle body 12. During this process, the heat-conducting oil absorbs the heat transferred by the rotating plate 22 while flowing along the spiral path around the periphery of the kettle body 12. As the rotating plate 22 continues to rotate, new heat-conducting oil is continuously involved in the area in contact with the rotating plate 22, absorbs heat and then starts to move in a continuous spiral upward motion. The high-temperature heat-conducting oil that has risen to a certain height will gradually cool down, increase in density, and under the action of gravity and the subsequent hot oil, will flow downward along the edge of the jacket 121, forming a circulating flow path around the periphery of the kettle body 12. In this cycle, the heat-conducting oil continuously transfers the heat obtained from the rotating plate 22 to the kettle body 12, and then uniformly heats the substances in the kettle body 12; The rotating plate 22 prompts the heat-conducting oil to form a spiral upward flow, greatly increasing the contact area and contact frequency between the heat-conducting oil and the rotating plate 22 and the kettle body 12, making the heat-conducting oil evenly distributed around the periphery of the kettle body 12, and avoiding the phenomenon of local overheating or overcooling.

[0028] The heating plate 23 is integrally in a spiral structure, and the length of the spiral line of the heating plate 23 is one-third of the length of the spiral line of the rotating plate 22. The three heating plates 23 are arranged on the rotating plate 22 at intervals and are respectively fixedly connected to the bottom, middle and top of the spaced rotating plate 22.

[0029] It should be noted that the length of the spiral line of the heating plate 23 is one-third of the length of the spiral line of the rotating plate 22. This length ratio makes the distribution of the heating plate 23 on the rotating plate 22 reasonable. It will not be too long to cause excessive local heat concentration, nor too short to result in insufficient heating range. When the rotating plate 22 rotates, the heating plate 23 can heat the heat-conducting oil at a suitable rhythm and range, ensuring that the heat-conducting oil can gradually and evenly absorb heat throughout the space of the jacket 121, and can heat the heat-conducting oil from multiple levels simultaneously, avoiding local overheating or overcooling caused by a single heating position. After the heating plate 23 is powered on, the heating elements inside generate heat. Since the heating plate 23 itself has a certain thermal conductivity, the heat will conduct inside its spiral structure. At the same time, the heating plate 23 is in direct contact with the surrounding heat-conducting oil, and transfers the heat to the heat-conducting oil through heat conduction. The three heating plates 23 are respectively arranged at the bottom, middle and top of the rotating plate 22. During rotation, they can heat the heat-conducting oil at different height positions. The heating plate 23 at the bottom can heat the heat-conducting oil near the bottom of the kettle body 12, the heating plate 23 in the middle is responsible for heating the heat-conducting oil in the middle layer, and the heating plate 23 at the top heats the upper heat-conducting oil, thus realizing all-round and multi-level heating and ensuring the temperature consistency of each part of the kettle body 12.

[0030] See Figure 4 and Figure 7 As shown, on the side of the spaced rotating plate 22 close to the kettle body 12, jet holes 220 are provided, and the opening of the jet hole 220 on the side in the rotation direction is larger than the opening on its back.

[0031] It should be noted that when the heat-conducting oil flows into the jet hole 220 from the side in the rotation direction (the large-opening side), due to the large opening providing a larger inlet area, the heat-conducting oil can enter the jet hole 220 more smoothly. When the heat-conducting oil flows out from the back of the jet hole 220 (the small-opening side), according to the principle of fluid continuity, in the case of steady flow, the flow rate of the fluid through each cross-section of the same flow tube is equal. The cross-sectional area at the small opening becomes smaller, resulting in an increase in the flow rate of the heat-conducting oil. On the one hand, the high-speed flowing fluid can more quickly carry away the heat boundary layer on the surface of the kettle body 12, and the jet impact on the surface of the kettle body 12 can enhance the heat exchange between the heat-conducting oil and the kettle body 12, making the heat transfer more efficient; on the other hand, the impact of the jet on the surrounding heat-conducting oil will destroy the original flow pattern, generating local turbulence and disturbances, making the temperature distribution more uniform.

[0032] See Figure 1 、 Figure 3 and Figure 8 As shown, the driving assembly 211 includes: a connecting seat 212, one end of which is installed at the front end of the moving seat 15, and the other end of which is rotatably connected to the driving roller 16 through a bearing; two transmission roller wheels 213, which are respectively installed on the top of the driving roller 16 and rotatably connected above the middle of the connecting seat 212; a conveyor belt 214, which is transmission-connected to the two transmission roller wheels 213; a linkage cover 215, which is fixedly connected to the sealing cover 24; a transmission gear 216, which is rotatably connected inside the linkage cover 215; a transmission connection assembly, which is arranged on the linkage cover 215 and is used to transmit the power of the transmission roller wheel 213 located in the middle of the connecting seat 212 to the transmission gear 216; a rotating wheel 217, which is rotatably connected inside the sealing cover 24 and meshes with the transmission gear 216. The rotating wheel 217 is arranged on the top of the rotating plate 22. When the rotation speed of the driving roller 16 changes, it will finally adjust the rotation speed of the rotating plate 22 through the cooperation of the above-mentioned transmission components in sequence, so as to realize the dynamic adjustment of the stirring and heat transfer efficiency of the heat-conducting oil, and ensure that the raw materials in the kettle body 12 react under a suitable temperature environment.

[0033] It should be noted that when the driving roller 16 rotates, the transmission roller wheel 213 installed on the top of the driving roller 16 rotates synchronously. The two transmission roller wheels 213 are transmission-connected through the conveyor belt 214, so that the other transmission roller wheel 213 rotatably connected above the middle of the connecting seat 212 also starts to rotate, thereby laterally transmitting the rotation power of the driving roller 16 to the middle position of the connecting seat 212. The transmission connection assembly is arranged on the linkage cover 215, and its function is to transmit the rotation power of the transmission roller wheel 213 in the middle of the connecting seat 212 to the transmission gear 216 rotatably connected inside the linkage cover 215. When the transmission gear 216 obtains power and starts to rotate, the rotating wheel 217 meshing with it also rotates inside the sealing cover 24. The rotation of the rotating wheel 217 can drive the rotating plate 22 to rotate around its central axis, and can accurately transmit the rotation speed of the stirring rod 17 to the rotating plate 22. The rotation speed of the rotating plate 22 can be adjusted through transmission components such as the driving roller 16 according to needs. Different rotation speeds will cause the heat-conducting oil to flow and stir to different degrees, so that the temperature distribution of the heat-conducting oil in the kettle body 12 is more uniform. Moreover, when it is necessary to quickly increase the temperature of the raw materials, the rotation speed of the driving roller 16 can be increased, and then the rotation speed of the rotating plate 22 can be accelerated. The rapid rotation of the rotating plate 22 will enhance the stirring effect on the heat-conducting oil, accelerate the flow speed of the heat-conducting oil, thereby increasing the heat exchange frequency and efficiency between the heat-conducting oil and the raw materials, enabling the raw materials to absorb heat faster and realizing rapid heating; See Figure 3 、 Figure 8 、 Figure 9 and Figure 10As shown in the figure, a lifting rod 221 slidably connected to the moving seat 15 is installed on one side of the top of the support seat 1. The top of the lifting rod 221 is installed with an L-shaped seat 222. On the other side of the top of the support seat 1, a lifting wire wheel 223 threadedly connected to the moving seat 15 is rotatably connected. The top of the lifting wire wheel 223 rotatably passes through the horizontal end of the L-shaped seat 222 and is installed with a turntable. The transmission connection assembly includes: a transmission seat 224, which is installed in the middle below the connection seat 212. A rotating rod is rotatably connected inside the transmission seat 224. The rotating rod is fixedly connected to a transmission roller 213 located in the middle of the connection seat 212; a limiting member 225, which is installed below the rotating rod. The top of the linkage cover 215 is rotatably connected to a limiting seat 226 fixedly connected to the transmission gear 216. The limiting member 225 abuts against the inside of the limiting seat 226.

[0034] It should be noted that when the operator rotates the turntable, the turntable drives the connected lifting wire wheel 223 to rotate. The moving seat 15 will move vertically along the guide of the lifting rod 221. The movement of the moving seat 15 will drive the connection seat 212 installed at its front end to move synchronously. And the connection seat 212 is also rotatably connected to the driving roller 16. Therefore, the driving roller 16 will also move up or down with the connection seat 212, which is convenient for processing the raw materials in the kettle body 12, such as feeding, discharging, or performing maintenance operations inside the equipment. During the descending process, the limiting member 225 and the limiting seat 226 need to maintain a limiting connection. This is because during the descending and resetting process of the equipment, it is necessary to ensure that all components of the transmission connection assembly can accurately return to their positions to avoid the equipment being unable to work properly due to position deviation. By simply rotating the turntable, the lifting of the kettle cover 13 can be realized. The operation method is intuitive and convenient, and the height of the kettle cover 13 can be adjusted at any time according to actual needs, which is convenient for performing various operations on the raw materials in the kettle body 12 and improves production efficiency.

[0035] See Figure 1 、 Figure 3 、 Figure 10 and Figure 11As shown in the figure, an axial flow cooling assembly 3 is provided at the bottom of the kettle body 12 for quickly and uniformly cooling the heat-conducting oil. The axial flow cooling assembly 3 includes: a cooling pipe 31, one end of which is installed above the kettle cover 13, and the end of the cooling pipe 31 away from the kettle cover 13 is connected to an external circulation pump; a cooling tank 32, which is symmetrically opened above the sealing cover 24, a rotary joint 33, the fixed end of which is installed on the top wall of the rotary collecting seat 35, and the rotating end of which is fixedly connected to the inner wall of the rotary wheel 217, the top of the rotating plate 22 is installed below the rotary joint 33, and the inlet end of the cooling tank 32 is communicated with the water inlet end of the rotary joint 33; cooling holes 34, which are opened inside the rotating plate 22, the water outlet end of the rotary joint 33 is communicated with the cooling holes 34 at the top of the rotating plate 22, and the cooling holes 34 are arranged in a spiral shape inside the rotating plate 22; a rotary collecting seat 35, one end of the top of which is installed below the rotating plate 22, and the other end of the bottom is rotatably connected to the top of the fixed disk 21. A drain hole is opened in the rotary collecting seat 35, and a collecting hole is opened in the fixed disk 21 on one side relative to the drain hole; a drain groove 36, a drain groove 36 communicated with the collecting hole is opened at the bottom of the kettle body 12, and a drain pipe 37 connected to the drain groove 36 is installed at the bottom of the kettle body 12.

[0036] It should be noted that after the external circulation pump is started, it generates power to drive the flow of the coolant. The coolant is first transported through the cooling pipe 31, and the coolant then enters the internal space of the kettle cover 13. Next, the coolant continues to flow through the cooling tank 32 symmetrically opened above the sealing cover 24. The cooling tank 32 serves to guide the coolant flow to the rotary joint 33. The rotary joint 33 has a special structure. The coolant enters the water inlet end of the rotary joint 33 from the inlet end of the cooling tank 32. Since the rotary joint 33 can ensure the continuous transportation of the coolant when the rotary wheel 217 rotates, the coolant smoothly enters the cooling holes 34 at the top of the rotating plate 22 from the water outlet end of the rotary joint 33. When the coolant flows through these spiral cooling holes 34, with the rotation of the rotating plate 22, the coolant continuously flows in the cooling holes 34. During the flow process, the coolant undergoes sufficient heat exchange with the rotating plate 22, absorbing the heat from the heat-conducting oil transferred by the rotating plate 22, thereby realizing the indirect cooling of the heat-conducting oil. After the heat exchange is completed, the coolant flows out of the cooling holes 34 and enters the rotary collecting seat 35. The top of the rotary collecting seat 35 is connected to the rotating plate 22, and the bottom is rotatably connected to the top of the fixed disk 21. The coolant is discharged through the drain holes in the rotary collecting seat 35, then enters the corresponding collecting holes on the fixed disk 21. The coolant flowing out of the collecting holes enters the drain groove 36 at the bottom of the kettle body 12, and finally is discharged from the equipment through the drain pipe 37, completing a complete coolant cycle; It should be noted that in the axial flow cooling assembly 3, a temperature detector is also provided in the area of the heat-conducting oil inside the jacket 121 to monitor the temperature of the heat-conducting oil in real time. Once the temperature sensor detects that the temperature of the heat-conducting oil rises and exceeds the normal range, approaching or reaching the higher temperature threshold T, the control system determines that the cooling demand increases, and then sends an instruction to the external circulation pump to increase the power.

[0037] When the driving assembly 211 works, it drives the rotating plate 22 to rotate around its central axis. Since the top of the rotating plate 22 is connected to the cooling system through a rotating joint 33, during the rotation, the coolant can be ejected from the cooling holes 34 on the multiple rotating plates 22. This rotating spraying method makes the distribution of the coolant in the space of the jacket 121 more uniform, increasing the heat exchange area between the coolant and the heat-conducting oil. At the same time, the rotating collecting seat 35 rotates together with the rotating plate 22, continuously collecting the coolant discharged from the cooling holes 34 during the rotation process, and guiding it to the collecting hole of the fixed plate 21 through the drain hole. The rotation of the rotating collecting seat 35 ensures the smoothness of the coolant during the discharge process, avoiding the influence on the cooling effect due to the accumulation of the coolant. The cooling holes 34 are arranged in a spiral shape, greatly extending the contact time between the coolant and the rotating plate 22. In the same time, the coolant can absorb more heat of the heat-conducting oil conducted from the rotating plate 22, improving the cooling efficiency. Moreover, the coolant is ejected from multiple rotating plates 22. When the rotating plate 22 rotates, the coolant can be evenly distributed in the space of the jacket 121, enabling the heat-conducting oil to be evenly cooled throughout the entire area of the jacket 121, avoiding problems such as local overheating or uneven cooling, ensuring the temperature consistency during the spinning oil agent configuration process, and being beneficial to improving the product quality.

[0038] A method for using a high-precision spinning oil agent configuration device includes the following steps: First, the jacket 121 is installed outside the kettle body 12, and heat-conducting oil is introduced to regulate the temperature. The temperature sensor in the kettle body 12 monitors the temperature of the spinning oil agent in real time. The motor is installed on the side opposite to the kettle body 12, and drives the driving roller 16 to rotate through the driving wheel and the connecting belt, thereby enabling the stirring rod 17 to stir the spinning oil agent in the kettle body 12. Second, connect the inlet oil pipe 25 to the oil transfer pump, inject heat-conducting oil into the jacket 121 and then close the control valve to form a closed space. Start the heating plate 23, and the driving assembly 211 drives the rotating plate 22 to rotate around the fixed plate 21. The rotating plate 22 stirs the heat-conducting oil to form forced convection, accelerating the flow and mixing of the heat-conducting oil and enabling it to be evenly heated quickly. Third, the rotating plate 22 is in a spiral shape, and when it rotates, it forms a spiral flow field. Under its action, the heat-conducting oil spirally rises, circulates, and evenly heats the substances in the kettle body 12. Fourth, the heating plate 23 is spiral and its length is one-third of the spiral line of the rotating plate 22. The three heating plates 23 are spaced apart and distributed at the bottom, middle, and top of the rotating plate 22 to heat the heat-conducting oil in multiple layers. The jet holes 220 of the rotating plate 22 increase the flow rate of the outflowing heat-conducting oil, enhance the heat exchange with the kettle body 12, and disturb the surrounding heat-conducting oil to ensure uniform temperature. Fifth, the external circulation pump drives the coolant to enter the kettle cover 13 through the cooling pipe 31, flow through the cooling tank 32 to the rotary joint 33, and enter the spiral cooling holes 34 inside the rotating plate 22. The coolant exchanges heat with the rotating plate 22 in the cooling holes 34, absorbs the heat of the heat-conducting oil, and realizes indirect cooling. The coolant after heat exchange flows into the rotary collecting seat 35, and is discharged from the drain pipe 37 through the drain hole, the collecting hole of the fixed plate 21, and the drain tank 36 to complete the cycle. Sixth, the driving assembly 211 drives the rotating plate 22 to rotate. The coolant sprays out from the cooling holes 34 of the multiple rotating plates 22 and is evenly distributed in the space of the jacket 121 to increase the heat exchange area with the heat-conducting oil. The rotary collecting seat 35 rotates to ensure smooth discharge of the coolant.
