Description

Technical Field

[0001] This invention relates to the field of chemical equipment technology, specifically to a rapid cooling device for fluid chemical raw materials. Background Technology

[0002] Fluid chemical raw materials are a class of core intermediate products or raw materials with fluidity in the chemical production process. They encompass various forms such as liquid and gas-liquid mixtures, and their compositions are complex and diverse. They are characterized by corrosiveness, heat sensitivity, and large differences in viscosity. They are widely used in many fields such as petrochemicals, fine chemicals, and pharmaceutical chemicals. The quality stability of these raw materials directly determines the quality of subsequent products. Their physicochemical properties place strict requirements on the processing technology. Targeted process methods are needed to ensure their performance stability and avoid compositional changes or quality deterioration due to external factors. Cooling fluid chemical raw materials is a key unit operation in chemical production. The core purpose is to reduce the temperature of fluid chemical raw materials to the preset process range through reasonable heat exchange methods to meet the requirements of subsequent storage, reaction, separation and other processes. At the same time, it is necessary to inhibit adverse reactions such as decomposition, polymerization, and deterioration of raw materials due to high temperatures, and reduce raw material loss and safety hazards. In the current technical field, the cooling process for fluid chemical raw materials is currently limited to a single mode and lacks a systematic design for staged cooling. This results in low heat exchange efficiency and long cooling cycles, making it unsuitable for the needs of large-scale, high-precision industrial production. Furthermore, the raw material feeding stage is prone to impact disturbances due to potential energy differences, leading to the generation of a large amount of foam. The lack of effective flow stabilization and degassing processes not only causes the loss of effective components in the raw material but also disrupts the uniformity of heat exchange, resulting in significant fluctuations in the quality of the cooled material. This makes it difficult to meet the process parameters of subsequent processes. Moreover, the structure of the enhanced heat exchange mechanism is simple and cannot be flexibly adjusted according to process parameters such as material viscosity and target cooling precision. This easily leads to heat exchange deviations such as local overcooling and local temperature non-compliance, making it difficult to control the cooling precision within the preset range and affecting the final product quality.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Through the extension and retraction of the multi-stage electric telescopic rods, the second mounting frame and the tank below are raised and lowered to the designated height. The electric telescopic rods extend and retract synchronously, driving the tilting frame to deflect via the connecting rods, adjusting the tilt angle of the diversion frame to ensure that the diversion frame is adapted to the height of the tank and aligned with the bottom of the tank inlet, avoiding impact and foaming caused by high-temperature raw materials falling from a height. The feed pump pumps the high-temperature fluid chemical raw materials from the outside into the tank through the matching pipeline. The raw materials flow smoothly into the tank along the diversion frame. The third motor drives the rotating blades to rotate at a uniform speed, breaking the raw materials into a uniform liquid film, allowing it to flow smoothly along the inner wall of the tank into the lower part of the tank until the liquid surface submerges the heat conduction pipe. The refrigeration equipment adjusts the heat conduction medium to room temperature and delivers it into the heat conduction pipe. The heat conduction medium circulates and absorbs the heat of the raw materials, completing the pre-cooling of the raw materials. The hot steam generated during the pre-cooling process enters the steam recovery equipment through the exhaust port at the top of the tank for centralized collection and treatment.

[0016] 2. After the pre-treated chemical raw materials in the tank are pressurized by the transfer pump, they are transported to the inner cavity of the cooling tank through a dedicated pipeline. The refrigeration equipment switches to low-temperature operation, adjusts the heat transfer medium to the set low temperature, and transports it into the cooling shell. Through heat exchange through the circulation of the heat transfer medium, rapid and deep cooling of the raw materials in the tank is achieved. During the cooling process, two enhanced heat exchange modes can be switched according to process requirements. The first motor drives the connecting shaft to drive the rotating frame to revolve. The driven gear meshes with the ring internal gear, driving the stirring rod to perform a compound motion combining revolution and rotation, which cools the tank. The raw materials inside are uniformly stirred throughout the tank to accelerate cooling. The second motor drives the arc-shaped chute frame to rotate via the drive shaft. With the help of the spherical four-bar linkage composed of the tank body seat and the connecting seat, the actuating plate is driven to swing back and forth, disturbing the raw materials in the middle of the tank. The miniature electric telescopic rod can adjust the axial position of the tank sleeve to change the included angle of the mechanism, thereby adjusting the swing angle of the actuating plate to adapt to different cooling requirements. When the raw materials in the tank are cooled to the preset temperature, the discharge pump starts and smoothly pumps the cooled chemical raw materials to the subsequent external processes, completing the entire rapid cooling process.

[0017] In summary, this invention enables graded and progressive cooling, optimizes heat exchange efficiency through segmented heat exchange design, significantly shortens the cooling cycle, and can stably adapt to large-scale, high-precision industrial production scenarios, meeting high-specification production requirements. It effectively buffers the potential energy impact during the feeding stage, suppresses foam formation, and ensures the material remains in a stable flow state through flow stabilization and degassing processes, reducing the loss of effective components in the raw materials, improving heat exchange uniformity, and ensuring stable and uniform material quality after cooling. Furthermore, it features a flexibly switchable enhanced heat exchange mode, which can adaptively adjust the heat exchange disturbance method according to process parameters such as material viscosity and target cooling precision, balancing uniform heat exchange across the entire area with localized enhanced disturbance. This effectively avoids heat exchange deviations such as localized overcooling and substandard local temperatures, precisely controls cooling precision, and ensures product quality stability and consistency.

There are two second connecting grooves 424, which are respectively opened on the front and rear sides of the bottom end of the rotating arm 422. The two second connecting grooves 424 are respectively fitted onto the outside of the two first connecting pins 414.

[0024] As a preferred option, further, such as Figure 5 and Figure 6As shown, the pretreatment mechanism 5 includes: a tank 51, a mounting joint 52, a sealing gasket 53, a heat-conducting pipe 54, a multi-stage electric telescopic rod 55, a second mounting frame 56, a second fixing frame 57, a tank 58, rotating blades 59, a third motor 510, a transmission belt assembly 511, a tilting frame 512, a diversion frame 513, an electric telescopic rod 514, and a connecting rod 515. The tank 51 is fixedly installed on the top of the base platform 1 in the left-right direction and is located below the inner side of the working platform 9. The liquid inlet of the tank 51 is connected to the top liquid outlet pipe of the feed pump 7, the left liquid outlet of the tank 51 is connected to the liquid inlet pipe of the transfer pump 8, and the top exhaust port of the tank 51 is connected to the steam recovery equipment 10. The air inlet pipe is connected; the mounting joint 52 is embedded in the right side of the outer surface of the tank 51; the sealing gasket 53 is detachably installed on the right side of the mounting joint 52; the heat conduction pipe 54 is installed at the bottom of the inner cavity of the tank 51 along the left and right direction through the fixing bracket, and the liquid inlet and return port of the right end of the heat conduction pipe 54 extend out of the outside of the sealing gasket 53 and are connected to the refrigeration equipment 11. The heat conduction pipe 54 is arranged in a serpentine pattern. The heat conduction pipe 54 serves as the heat exchange carrier for the pre-cooling process. The room temperature heat conduction medium provided by the refrigeration equipment 11 is introduced, and the heat is continuously absorbed from the high-temperature chemical raw materials inside the tank 51 through the indirect heat exchange method to achieve the pre-cooling treatment of the raw materials; the multi-stage electric telescopic rod 55 is fixed along the up and down direction. Installed at the top of the inner cavity of tank 51, and located at the bottom left rear of the liquid inlet of tank 51, the multi-stage electric telescopic rod 55 is electrically connected to the controller 2. The multi-stage electric telescopic rod 55 is a high-precision multi-stage telescopic electric push rod, and its telescopic movement is precisely controlled by the controller 2. Through its own telescopic movement, it drives the second mounting frame 56 below to rise and fall vertically. Then, with the cooperation of the second fixed frame 57, it drives the tank 58 to adjust to the preset height, changing the relative height between the rotating blade 59 and the feed drop point, avoiding impact, splashing, and foam entrainment of high-temperature raw materials due to excessive drop, and adapting to the pretreatment needs of chemical raw materials with different viscosities and feed rates; the second mounting frame 56 extends along the left and right sides. The first mounting bracket 57 is fixedly installed at the bottom of the telescopic end of the multi-stage electric telescopic rod 55; there are two second mounting brackets 57, which are respectively installed on the left and right sides of the bottom of the second mounting bracket 56 in the vertical direction; the tank 58 is installed on the bottom inner side of the two second mounting brackets 57. The tank 58 receives the high-temperature fluid chemical raw materials flowing in through the diversion frame 513, and provides a stable space for the rotating blades 59 to disperse the raw materials. Under the centrifugal action of the rotating blades 59, the raw materials form a uniform liquid film, and then slowly flow into the lower part of the inner cavity of the tank 51 along its inner wall, avoiding the raw materials from directly impacting the bottom of the tank, while reducing foam generation, and ensuring that the liquid inside the tank 51 remains in a stable state with low disturbance and no foam.Rotating blade 59 is mounted on the bottom right side of the second mounting bracket 56 via bearings in a vertical direction. The axis of rotating blade 59 extends to the upper surface of the second mounting bracket 56. Driven by the third motor 510, rotating blade 59 rotates at a uniform speed, using centrifugal force to disperse the chemical raw materials in the tank 58 into a uniform liquid film, increasing the contact area between the raw materials and air, facilitating foam rupture and degassing, and simultaneously ensuring a smooth flow of the raw materials into the lower part of the tank 51, avoiding splashing. This provides a uniform material state for the subsequent pre-cooling process, improving pre-cooling efficiency. The third motor 510 is mounted on the front left side of the second mounting bracket 56 and is electrically connected to the controller 2. The third motor 510 is a three-phase asynchronous motor, and its start / stop and speed are controlled by the controller 2. The drive belt assembly 511 provides stable power to the rotating blade 59, precisely transmitting its rotational motion to the blade 59 and driving it to rotate at a uniform speed. This ensures that the raw material is evenly dispersed into a film, meeting the defoaming, flow stabilization, and degassing requirements of the pretreatment process. One end of the drive belt assembly 511 is mounted on the top of the rotating end of the third motor 510, and the other end is keyed to the top of the shaft of the rotating blade 59. The drive belt assembly 511 is a synchronous belt assembly, consisting of a drive pulley, a driven pulley, and a synchronous belt. The drive pulley's belt shaft is mounted on the top of the rotating end of the third motor 510, and the driven pulley's belt shaft is keyed to the top of the shaft of the rotating blade 59. The synchronous belt is made of polyurethane material. The material is capable of transmitting the power of the third motor 510, accurately transmitting the rotational motion of the third motor 510 to the rotating blade 59, ensuring that the rotational speed of the rotating blade 59 is synchronized with that of the third motor 510; the tilting frame 512 is installed on the front side of the outer wall of the tank 58, and the tilting frame 512 carries the diversion frame 513. Under the linkage of the electric telescopic rod 514 and the connecting rod 515, it deflects around the hinge axis with the tank 58, thereby driving the diversion frame 513 to adjust the tilt angle, ensuring that the diversion frame 513 can accurately connect with the liquid inlet of the tank 51 and the tank 58, realizing the smooth diversion of raw materials and avoiding raw material leakage or impact on the tank 58; the diversion frame 513 is installed on the front side of the rotating end of the tilting frame 512 in the vertical direction; one end of the electric telescopic rod 514 passes through The rotating shaft seat is rotatably mounted on the front right end of the outer surface of the second mounting bracket 56. The electric telescopic rod 514 is electrically connected to the controller 2. The electric telescopic rod 514 is a small precision electric push rod, and its telescopic movement is controlled by the controller 2. Through its own telescopic movement, it pushes or pulls the connecting rod 515 to form a corresponding displacement, thereby driving the tilting frame 512 to deflect around the fixed hinge axis, adjusting the tilt angle of the diversion frame 513 in real time, so that the height position of the diversion frame 513 matches that of the tank 58, and aligns it with the area below the liquid inlet of the tank 51, ensuring that the raw material flows in smoothly along the preset path. One end of the connecting rod 515 is fixed to the outside of the axis of the tilting frame 512, and the other end of the connecting rod 515 is rotatably connected to the telescopic end of the electric telescopic rod 514 through a rotating shaft.

[0025] The specific work steps are as follows: Step 1: The operator operates and starts controller 2. Controller 2, according to its internal preset control program, starts the multi-stage electric telescopic rod 55, electric telescopic rod 514, feed pump 7, third motor 510, refrigeration equipment 11, and steam recovery equipment 10 to enter the working state and proceed to the pretreatment process, as detailed below: The multi-stage electric telescopic rod 55 drives the second mounting frame 56 to rise and fall vertically through its telescopic movement. Under the linkage of the second fixed frames 57 on both sides of the lower part of the second mounting frame 56, the tank 58 is adjusted to the set height position, thereby changing the relative height between the rotating blade 59 and the feed drop point. This avoids the raw material from being impacted, splashed, or entrained by excessive drop. While the height of the tank 58 is adjusted, the electric telescopic rod 514 moves in a telescopic motion, pushing or pulling the connecting rod 515 to form a corresponding displacement. This drives the tilting frame 512 to deflect around the fixed hinge axis, adjusting the tilt angle of the diversion frame 513 in real time so that the height position of the diversion frame 513 matches that of the tank 58 and is aligned with the area below the liquid inlet of the tank 51, ensuring that the raw material flows in smoothly along the preset path. The feed pump 7 pumps the external high-temperature fluid chemical raw material from the inlet of the tank 51 into the tank through the matching pipeline. The raw material flows smoothly into the tank 58 along the guide frame 513. The third motor 510 outputs power and drives the rotating blade 59 to rotate at a uniform speed. The chemical raw material entering the tank 58 is dispersed into a uniform liquid film under the centrifugal action of the rotating blade 59. It flows slowly and steadily into the lower part of the inner cavity of the tank 51 along the inner wall of the tank 58 until the liquid surface submerges the heat conduction pipe 54, so that the liquid inside the tank 51 is kept in a stable state of low disturbance, no foam, and rapid settling. Meanwhile, the refrigeration equipment 11 adjusts the heat transfer medium to a preset temperature and transports it to the heat transfer pipe 54 through a pipeline. The heat transfer medium continuously circulates in the heat transfer pipe 54 and indirectly exchanges heat with the high-temperature fluid chemical raw materials inside the tank 51 to achieve pre-cooling treatment of the raw materials. The hot steam generated during the pre-cooling process is collected from the exhaust port at the top of the tank 51 through a pipeline to the steam recovery equipment 10 to complete the centralized recovery and treatment of high-temperature steam. Step 2: Controller 2 starts the transfer pump 8, the first motor 35, the second motor 416, the refrigeration equipment 11, and the discharge pump 6 according to the preset program, entering the deep cooling process, as follows: The pretreated chemical raw materials flow out from the lower outlet of the tank 51, are pressurized by the transfer pump 8, and are then transported through pipelines to the tank 34 inside the cooling mechanism 3. The refrigeration equipment 11 adjusts the heat transfer medium to a low-temperature cooling condition and transports it through pipelines to the cooling shell 33. The low-temperature heat transfer medium continuously circulates in the cooling shell 33 and exchanges heat with the chemical raw materials in the tank 34 in a wall-to-wall manner to achieve rapid and deep cooling of the raw materials.

[0026] During the cooling process, the device can switch between two enhanced heat exchange modes according to process requirements: Full-area large-scale stirring mode: The first motor 35 drives the connecting shaft 43 to rotate, which drives the rotating frame 44 to make the driven gear 45 revolve in a circle. During the revolution, the driven gear 45 keeps meshing with the inner ring gear 42, so that it rotates on its own axis while revolving with the rotating frame 44, which in turn drives the stirring rod 46 to form a compound planetary motion of revolution and rotation, which stirs all the fluid raw materials in the tank 34 in a full-area manner, destroys the thermal boundary layer, and improves the overall cooling rate. Adjustable disturbance mode in the middle: When directional disturbance is required in the middle area of ​​the tank 34, the first motor 35 stops running, and the second motor 416 drives the drive shaft 415 to rotate, which drives the arc-shaped slide frame 417 to rotate synchronously. When the arc-shaped slide frame 417 rotates, it drives the tank seat 412 to move synchronously through the limit pin 413. Since the top of the tank seat 412 is rotatably connected to the connecting seat 411 through the bearing to form a spherical joint hinge, and the top of the connecting seat 411 is rotatably connected to the rotating seat 49 to form a spherical joint hinge, and the rotating seat 49 is rotatably installed on the lower inner side of the mounting frame 48 through the rotating shaft, the tank seat 412, the connecting seat 411, the rotating seat 49 and the mounting frame 48 are all connected. The frame 48 together constitutes a spherical four-bar linkage mechanism. Utilizing the spatial motion adaptation characteristics of the spherical pair, the circumferential rotational motion driven by the drive shaft 415 is constrained and transformed into the reciprocating angular swing of the rotating seat 49 along the fixed rotating shaft. When the rotating seat 49 swings back and forth, it directly drives the actuating plate 410 to swing back and forth in the middle of the inner cavity of the tank 34, disturbing the fluid chemical raw materials in the middle, breaking the thermal boundary layer, and assisting in accelerating cooling. At this time, the micro electric telescopic rod 419 is in a stationary state, the position of the tank sleeve 418 is fixed, and the included angle between the drive shaft 415 and the tank seat 412 remains unchanged. Therefore, the swing angle of the actuating plate 410 is fixed, and it continuously provides stable disturbance to the fluid in the middle. Step 3: When the swing amplitude of the toggle plate 410 needs to be adjusted according to the cooling requirements, the miniature electric telescopic rod 419 moves up and down, driving the annular plate 420 to move up and down synchronously. Since the outer side of the annular plate 420 is inserted into the groove of the outer wall of the groove sleeve 418, when the annular plate 420 moves, it drives the groove sleeve 418 to make axial linear displacement along the outer wall of the drive shaft 415. When the groove sleeve 418 moves axially, the second connecting pin 421 slides in the first connecting groove 423, pushing or pulling the rotating arm 422 to generate a certain angular displacement around its hinge point with the outer side of the arc-shaped slide frame 417. When the rotating arm 422 generates angular displacement, it drives the groove seat 412 to slide along the inner cavity of the arc-shaped slide frame 417 under the limiting action of the limiting pin 413 through the first connecting pin 414, so that the groove... The body seat 412 deflects around the spherical hinge point with the connecting seat 411, ultimately changing the spatial angle between the drive shaft 415, the arc-shaped slide frame 417, and the tank body seat 412. As the angle gradually increases, the swing angle of the rotating seat 49 increases synchronously and smoothly, the swing amplitude of the actuating plate 410 increases, and the disturbance range and intensity of the fluid in the middle of the tank 34 are enhanced. As the angle gradually decreases, the swing angle of the rotating seat 49 decreases synchronously, the swing amplitude of the actuating plate 410 decreases, and the disturbance range and intensity are weakened. When the angle is adjusted to 0°, the tank body seat 412, the drive shaft 415, and the arc-shaped slide frame 417 are arranged collinearly, the motion transmission chain of the spherical four-bar linkage is completely constrained, there is no relative motion between the links, the rotating seat 49 stops swinging, and the actuating plate 410 also stops, no longer disturbing the fluid. Once the desired swing angle is reached, the controller 2 controls the micro electric telescopic rod 419 to stop working, the position of the annular plate 420 and the groove sleeve 418 is fixed, the included angle remains unchanged, and the toggle plate 410 continues to swing or remain still at the adjusted fixed angle until the adjustment is restarted. Through this adjustment method, the range and intensity of fluid disturbance can be precisely controlled to meet the cooling requirements under different working conditions. Once the chemical raw materials in the tank 34 have cooled to the set temperature, the discharge pump 6 pumps the cooled raw materials to the subsequent process, completing the entire rapid cooling process.
