Description

Technical Field

[0001] This invention relates to the field of thermosensitive agent preparation technology, and more specifically to thermosensitive agent gradient concentration mixing equipment. Background Technology

[0002] Heat-sensitive agents, as important functional additives in the production of daily chemical, skin care, and topical health products, are mainly used to impart a warming sensation to products, enhancing the user experience and efficacy. The industrial-scale production of heat-sensitive agents requires multiple stages of meticulous formulation. First, in a primary reaction vessel, n-butanol, vanillin, and a specialized catalyst are etherified in a predetermined ratio to prepare a preliminary heat-sensitive agent solution. Then, a separation and purification process removes impurities and increases purity, yielding a high-purity heat-sensitive agent stock solution. Before the finished product leaves the factory, a secondary gradient concentration adjustment is performed according to the different product formulation requirements of various customers. Propylene glycol, glycerin, and other diluents are precisely added to the purified heat-sensitive agent stock solution to adjust the concentration of the finished product as needed, meeting the production adaptation requirements of different product categories.

[0003] During the initial etherification reaction of the heat-sensitive agent, solid catalyst residue is generated. When the initial liquid is output, it is filtered through the filter residue pipeline. After a single batch of production is completed, the catalyst residue accumulated inside the filter structure cannot be automatically cleaned and discharged. It is necessary for workers to manually disassemble various filter components for manual cleaning, which is time-consuming. At the same time, the catalyst in the cleaned residue can be reused. Workers also need to store and dry it separately, waiting for it to be added back into the catalyst tank later. Summary of the Invention

[0066] Example

[0067] To address the technical problems in the background section, the following equipment for adjusting the gradient concentration of heat-sensitive agents is provided:

[0068] Combination Figures 1-14 As shown, the heat-sensing agent gradient concentration mixing device provided by the present invention includes: a loading rack 100, which has a mixing layer 101, a neutralization layer 102, and a settling layer 103 arranged sequentially from top to bottom inside; a primary mixing vessel 111, a n-butanol tank 112, a vanillin tank 113, and a catalyst tank 114 installed on the mixing layer 101; a through-hole 104 is provided between the mixing layer 101 and the neutralization layer 102, and a conveying component 200 extending to the mixing layer 101 and the neutralization layer 102 is provided in the through-hole 104; a neutralization reaction vessel 121, a saturated brine tank 122, and a sodium bicarbonate tank 123 are installed on the neutralization layer 102; and a settling tank 131, a distillation tank 132, and a finished product mixing vessel 133 are installed on the settling layer 103.

[0069] The filter residue component 300 is installed at the input end of the neutralization reactor 121 and the output end of the primary preparation and mixing reactor 111. The filter residue component 300 contains a filter residue element 303.

[0070] The transmission component 400 is mounted on the conveying component 200;

[0071] The loading assembly 500 includes a loading vehicle 501, a drying component 502, an extraction component 503, and a feeding component 504. The loading vehicle 501 is mounted on the transmission component 400. The top of the loading vehicle 501 is provided with a loading slot 511 and the inside is provided with a receiving cavity 512. The extraction component 503 is installed inside the receiving cavity 512. The drying component 502 is mounted on the top of the receiving cavity 512. The feeding component 504 extending out of the loading vehicle 501 is installed inside the loading slot 511.

[0072] The recovery component 600 is installed on the mixing layer 101 and located below the catalyst tank 114. A feeding component 700 connected to the catalyst tank 114 is installed on one side of the recovery component 600.

[0073] The equipment dispatching includes the following operating modes:

[0074] In the feeding mode: Before the equipment operates, vanillin tank 113 and catalyst tank 114 input a certain amount of vanillin and catalyst into loading tank 511. The transmission component 400 pushes loading vehicle 501 to input port 115 of primary preparation mixing tank 111. Feeding component 504 connects with input port 115 and feeds in vanillin and catalyst.

[0075] In the slag removal mode: After the equipment operates, the conveying component 200 drives the loading vehicle 501 to descend to the neutralization layer 102 and makes the receiving cavity 512 correspond to the filter slag component 300; the extraction component 503 extends out from the receiving cavity 512 and docks with the filter slag component 303 for clamping and recycling; the drying component 502 hot-dries the filter slag component 303 extracted into the receiving cavity 512.

[0076] In the recycling mode: the conveying component 200 drives the loading vehicle 501 to rise to the mixing layer 101 and makes the receiving cavity 512 correspond to the recycling component 600; the extraction component 503 pushes the dried filter cake 303 into the recycling component 600 for filter cake recycling.

[0077] In the above scheme:

[0078] 1. Through the feeding component structure of the loading assembly, the feeding nozzle is connected to the input port of the primary mixing vessel, and the pushing action is coordinated with the lifting and lowering of the baffle plate. Combined with the automatic switching design of the opening and closing components, the safe feeding of vanillin, catalysts and other materials can be achieved, avoiding abnormal reactions caused by material leakage and premature contact.

[0079] 2. The loading tank of the loading component provides temporary quantitative storage space for vanillin and catalyst. In conjunction with the linkage between the push plate and the triangular guide plate of the pusher, the automatic lifting and lowering of the baffle plate and the material push are synchronized.

[0080] 3. The meshing design of the rack and pinion of the feeding nozzle and the gear of the input port ensures that the feeding component is connected to the input port of the primary mixing vessel, structurally eliminating material feeding deviation, laying the foundation for reaction stability, and highlighting the core role of the loading component in material feeding.

[0081] 4. The telescopic, movable, and clamping structure of the extraction component allows for flexible adjustment of the telescopic length and clamping angle, enabling the transfer of filter cake components. The air-drying component quickly removes residual filtrate from the surface of the filter cake components, ensuring subsequent residue cleaning and recycling, and improving the continuity and stability of filter cake operations.

[0082] 5. The air-drying component at the top of the receiving cavity, through the cooperation of a fan and an electric heating plate, quickly dries the residual filtrate on the surface of the filter cake. The structural design of the loading vehicle provides a stable mounting carrier for the extraction and air-drying components, ensuring that the filter cake transfer and air-drying operations are carried out in an orderly and efficient manner, highlighting the key supporting role of the loading component in the filter cake operation.

[0083] 6. Through the synergy of the recovery component and the cleaning component, the cleaning component can thoroughly and efficiently clean the catalyst residue on the filter cake. The inclined bottom design of the recovery tank ensures that the residue is quickly collected, and the feeding auger realizes the transfer of the residue to the catalyst tank.

[0084] In this embodiment, the filter residue component 300 includes a filter residue box 301 and two sets of connecting pipes 302. The top and bottom of the filter residue box 301 are equipped with connecting pipes 302. The filter residue box 301 is connected to the input end of the neutralization reactor 121 and the output end of the primary preparation reactor 111 through the connecting pipes 302. The filter residue component 303 includes a front sealing plate 331 and a filter residue screen plate 332. A plug-in interface 304 is provided on one side of the filter residue box 301. The front sealing plate 331 is connected to the plug-in interface 304. A clamping opening 333 is provided on the outer side of the front sealing plate 331.

An electric latch 334 is fixedly installed on the filter residue box 301 above the front sealing plate 331. The electric latch 334 is used to lock the clamping opening 333. Through the structural design of the filter cake box and two sets of connecting pipes, the filter cake component is synchronously connected to the output end of the primary mixing vessel and the input end of the neutralization reaction vessel. This allows for the simultaneous completion of the filter cake operation for the post-reaction mixture and the pre-treatment filtrate, thereby improving the filter cake efficiency. The locking of a pair of front-mounted sealing plate clamps by an electric pin ensures that the filter cake component is securely installed, preventing loosening and leakage during the filter cake process.

[0085] In this embodiment, the conveying component 200 includes a vertical frame 201 and an active guide rail 202. The vertical frame 201, which has a through-hole 104 and extends to the mixing layer 101, is fixedly connected to the neutralizing layer 102. The active guide rail 202 is fixedly installed on the vertical frame 201.

[0086] The transmission component 400 includes a back plate 401, a bracket 402, a second active guide rail 403, a carrier plate 404, and an active rotary cylinder 405. The back plate 401 is fixedly installed at the guide end of the first active guide rail 202. The bracket 402 is fixedly installed at the bottom of the back plate 401.

The rotating surface of the active rotary cylinder 405 is connected to the bottom of the loading vehicle 501. Through the transmission component consisting of the vertical frame and the first active guide rail, stable lifting and lowering of the transmission component and the loading vehicle between the mixing layer and the neutralization layer is achieved, ensuring smooth movement of the loading vehicle between different floors. Through the transmission component consisting of the back plate, bracket, second active guide rail, and carrier plate, horizontal movement of the loading vehicle can be achieved, coordinated with the rotation adjustment of the active rotary cylinder.

[0087] In this embodiment, the extraction component 503 includes an active guide rail 531, a mounting box 532, a mounting plate 533, a scissor-type telescopic frame 534, and an active gripper 535. Two sets of active guide rails 531 are fixedly installed inside the receiving cavity 512. The mounting box 532 is fixedly installed at the guide ends of the active guide rails 531. The scissor-type telescopic frame 534 is slidably hinged inside the mounting box 532. The mounting plate 533 is fixedly installed at the front end of the scissor-type telescopic frame 534, and the active gripper 535 is fixedly installed on the mounting plate 533. The active gripper 535 is used to fit and clamp the clamping opening 333 on the front sealing plate 331. The active guide rail drives the mounting box to move, achieving horizontal extension and retraction of the extraction component. Combined with the scissor-type telescopic frame inside the mounting box, the extension length of the active gripper can be flexibly adjusted to ensure that the active gripper can engage with the clamping opening of the filter cake. The structural design of the active gripper ensures secure clamping of the filter cake, preventing it from falling off or being damaged during extraction and transfer.

[0088] In this embodiment, the drying component 502 includes a fan 521 and an electric heating plate 522. Multiple sets of fans 521 are fixedly installed on the top of the receiving cavity 512, and the electric heating plate 522 is fixedly installed in the receiving cavity 512 below the fans 521. Air inlets 523 are provided on both sides of the carrier plate 404 near the fans 521. The drying component is formed by the fans on the top of the receiving cavity and the electric heating plate below. The fans can blow the heat generated by the electric heating plate evenly onto the filter cake, realizing the rapid hot air drying of the residual filtrate on the surface of the filter cake. The air inlets on both sides of the carrier plate can replenish fresh air, ensuring air circulation during the drying process, improving the drying efficiency and drying effect, avoiding the residual filtrate from affecting the cleaning and recycling of the filter cake, and providing structural support for the smooth implementation of the subsequent recycling mode.

[0089] In this embodiment, the feeding component 504 includes a feeding nozzle 541, a pusher 505, a baffle plate 542, and a slide bar 543. The feeding nozzle 541 is fixedly connected to one side of the loading vehicle 501. A discharge port 513 is provided on the loading vehicle 501 between the feeding nozzle 541 and the loading groove 511. A baffle plate 542 inserted into the discharge port 513 is installed on the top of the loading vehicle 501, and slide bars 543 are provided on the top of both sides of the baffle plate 542.

[0090] The pusher 505 includes an active guide rail 551, a pusher frame 552, a pusher plate 553, and a triangular guide plate 554. The active guide rail 551 is installed on both sides of the loading vehicle 501. The pusher frame 552 is fixedly installed on the guide end of the active guide rail 551. The pusher plate 553 extending into the loading groove 511 is fixedly installed on the pusher frame 552 on both sides of the pusher plate 553. The triangular guide plate 554 is located on both sides of the top of the loading groove 511. The triangular guide plate 554 is used to push the slide bar 543 to raise and lower the baffle plate 542. The corresponding design of the inlet and outlet, along with the push plate of the pusher, enables the material to be pushed into the loading trough, preventing material leakage. The design of the triangular guide plate and the slide bar allows for coordinated action between the pushing action and the lifting action of the baffle plate. The baffle plate automatically rises when pushing material and automatically falls to close the outlet after pushing, preventing material residue and leakage. The rack on one side of the inlet engages with the gear of the inlet opening and closing component, enabling the cover plate to open automatically when the inlet is docked and to close automatically after docking, without the need for manual assistance.

The recycling tank 601 is mounted on the mixing layer 101, and the cleaning component 602 is installed inside the recycling tank 601. The recycling tank 601 is located below the catalyst tank 114, and an inlet 603 is provided on the side of the recycling tank 601 near the vertical frame 201. Through the integrated design of the recycling tank and the cleaning component, the cleaning and collection of residues on the filter cake can be integrated. The cleaning component can clean the catalyst residues on the filter cake into the recycling tank, avoiding residue residue. The layout of the recycling tank below the catalyst tank, together with the feeding component, can realize the rapid transfer and reuse of recycled residues.

[0092] In this embodiment, the cleaning component 602 includes an active guide rail 621, a drive spindle 622, and a cleaning brush 623.

The drive spindle 622 is rotatably mounted inside the active lifting frame 624, and the cleaning brush 623 is mounted on the drive spindle 622. The cleaning brush 623 is located above the inlet 603 and is used to clean catalyst residue on the filter screen 332. The active lifting frame on the crossbeam allows for the adjustment of the drive spindle and the cleaning brush. Combined with the rotation of the drive spindle, the cleaning brush can fully cover all areas of the filter screen, achieving comprehensive and efficient cleaning of residue. The cleaning brush mounted on the drive spindle can flexibly adapt to the size of the filter screen, minimizing wear on the filter screen during cleaning and preventing damage to the filter components.

[0093] In this embodiment, the feeding component 700 includes a feeding auger 701. The feeding auger 701 is fixedly installed on one side of the recovery tank 601, with its input end connected to the recovery tank 601 and its output end connected to the catalyst tank 114. The bottom surface of the recovery tank 601 is inclined, and the lowest point of the bottom surface is located at the input port of the feeding auger 701. Through the structural design of the feeding auger, precise communication between the residue in the recovery tank and the catalyst tank is achieved, allowing the recovered catalyst residue to be quickly transferred to the catalyst tank, realizing material reuse and reducing material waste. The inclined design of the bottom surface of the recovery tank allows the residue to automatically collect to the lowest point under gravity, which corresponds to the input end of the feeding auger. This avoids residue accumulation and blockage, ensuring that the residue quickly enters the feeding auger, improving the efficiency of residue recovery and transfer, and achieving seamless connection between recovery and feeding.

[0094] In this embodiment, a rack 544 is fixedly installed on one side of the feeding nozzle 541; an opening and closing component 105 is installed on the input port 115 of the initial preparation mixing vessel 111. The opening and closing component 105 includes a cover plate 151, a flip shaft 152, a plug connector 153, a plug sleeve 154, and an electric pin 155. The flip shaft 152 is rotatably installed on the top of the input port 115, and the cover plate 151 is fixedly installed on the flip shaft 152. The cover plate 151 is used to close the input port 115. A gear 156 is fixedly installed on one end of the flip shaft 152. The gear 156 is used to mesh and drive with the rack 544. The plug sleeve 154 is fixedly installed on the bottom of the input port 115. The plug connector 153, which mates with the plug sleeve 154, is fixedly connected to the bottom of the cover plate 151. An electric pin 155 for positioning the plug connector 153 is fixedly installed on the plug sleeve 154. The automatic opening of the cover plate when the feed nozzle is connected to the gear on the tilting shaft via the meshing transmission of the rack on one side of the feed nozzle and the automatic closing of the cover plate when the feed nozzle is disconnected are achieved without manual operation, thus improving work efficiency. The plug at the bottom of the cover plate connects with the plug sleeve at the bottom of the input port, and with the positioning of the electric pin two, it can ensure a firm seal when the cover plate is closed, preventing material leakage or foreign matter from entering the primary preparation vessel, and ensuring the cleanliness and safety of the reaction environment.

[0095] Working principle and usage process of this invention:

[0096] Part 1: Preparation of the thermal sensitizer:

[0097] S1. Before starting the equipment, enter the feeding mode to complete the pre-loading of catalyst and vanillin. Vanillin tank 113 and catalyst tank 114 input vanillin and catalyst into the loading trough 511 on the top of loading vehicle 501 according to the preset amount; at this time, loading vehicle 501 is installed on the carrier plate 404 of the transmission component 400, and baffle plate 542 is in the closed state, blocking the discharge port 513 between loading trough 511 and feed nozzle 541 to prevent material leakage. At the same time, the input port 115 of the primary preparation mixing vessel 111 is in the closed state, and the cover plate 151 of opening and closing component 105 is connected to the plug sleeve 154 through plug connector 153. Electric pin 155 locks plug connector 153 to ensure that input port 115 is sealed.

[0098] S2. First, n-butanol is added: a preset amount of n-butanol is added directly into the primary preparation mixing vessel 111 through the n-butanol tank 112. The flow rate is strictly controlled during the addition process to avoid material splashing. Then, the transmission component 400 is activated, and the active guide rail 1 202 drives the back plate 401 to move the bracket 402, the carrier plate 404 and the loading vehicle 501, pushing the loading vehicle 501 to the input port 115 of the primary preparation mixing vessel 111. At this time, the feeding nozzle 541 on one side of the loading vehicle 501 is aligned with the input port 115. The rack 544 on the feeding nozzle 541 meshes with the gear 156 of the opening and closing component 105, driving the tilting shaft 152 to rotate, so that the cover plate 151 is opened. At the same time, the electric latch 2 155 unlocks the connector 153.

[0099] Next, the pusher 505 is activated, and the active guide rail 551 drives the pusher frame 552 to move the pusher plate 553 into the loading tank 511. Simultaneously, the triangular guide plate 554 on the pusher frame 552 pushes the sliding rods 543 on both sides of the baffle plate 542, causing the baffle plate 542 to rise and open the discharge port 513. The pusher plate 553 continues to push, pushing the vanillin in the loading tank 511 into the feed nozzle 541, which then enters the primary preparation mixing vessel 111 through the input port 115, completing the vanillin feeding. Finally, the catalyst tank 114, assisted by the feeding component 700, adds the catalyst into the primary preparation mixing vessel 111. The weighing of all three materials is performed accurately using either the weight reduction method or the weight gain method to ensure that the feeding accuracy meets the requirements.

[0100] S3. After the feeding is completed, close the input port 115 of the primary preparation mixing vessel 111, reset the opening and closing component 105, relock the electric latch 155, and start the stirring function of the primary preparation mixing vessel 111 to begin the reaction. During the reaction, samples are taken every 1 hour through the sampling port of the primary preparation mixing vessel 111 to monitor the reaction progress and material status, ensuring that the reaction proceeds smoothly without local overheating or runaway reaction. After the reaction is completed, a reaction mixture is obtained.

[0101] The reaction mixture is discharged from the output end of the primary mixing vessel 111 and filtered through the filter residue component 300: the mixture enters the filter residue box 301 through the connecting pipe 302 at the top of the filter residue box 301, and the filter residue screen 332 of the filter residue component 303 intercepts catalyst residues in the mixture. The filtered filtrate is then transported to the neutralization reaction vessel 121 of the neutralization layer 102 through the connecting pipe 302 at the bottom of the filter residue box 301. At this time, the filter residue component 303 is connected to the insertion interface 304 of the filter residue box 301 through the front sealing plate 331, and the electric latch 334 locks the clamping port 333 on the front sealing plate 331 to ensure that the filter residue component 303 is firmly fixed.

[0102] After the filtrate enters the neutralization reactor 121, pretreatment is carried out: saturated brine is added to the neutralization reactor 121 from the saturated brine tank 122, sodium bicarbonate is added from the sodium bicarbonate tank 123, and the stirring of the neutralization reactor 121 is started to fully mix the materials and complete the pretreatment.

[0103] S4. Purification and Concentration Adjustment:

[0104] The material in the neutralization reactor 121 is transported to the settling tank in the settling layer 103, so that the liquid can settle and precipitate.

[0105] The upper liquid is drawn into distillation tank 132 for distillation and purification.

[0106] The purified heat-sensitive agent is conveyed to the finished product mixing tank 133, and a diluent, including propylene glycol and glycerin, is added to the purified heat-sensitive agent to change the concentration of the finished product.

[0107] Part Two: Multi-mode operation for loading components:

[0108] S1, Feeding Mode:

[0109] The core of the feeding mode is to accurately feed vanillin and catalyst. In addition to the above steps, the active rotating cylinder 405 of the transmission component 400 can adjust the angle of the loading vehicle 501 according to the angle of the inlet 115 to ensure that the feed nozzle 541 is accurately connected to the inlet 115. After feeding is completed, the pusher 505 is reset, the baffle plate 542 falls to close the discharge port 513, the rack 544 reverses the transmission to drive the cover plate 151 to close, the electric latch 155 locks, and the transmission component 400 moves the loading vehicle 501 back to the initial position to wait for the subsequent slag removal operation.

[0110] S2, Slag Removal Mode:

[0111] After the loading vehicle is moved and the heat-sensitive agent gradient is adjusted, the equipment enters the slag removal mode. The active guide rail 202 of the conveying component 200 drives the back plate 401, bracket 402 and loading vehicle 501 to descend, and reach the neutralization layer 102 through the through hole 104. The position of the loading vehicle 501 is adjusted so that the receiving cavity 512 inside the loading vehicle 501 corresponds to the filter cake box 301 of the filter cake component 300, ensuring that the extraction component 503 can dock with the filter cake component 303.

[0112] When the extraction component 503 is activated, the active guide rail 3 531 drives the mounting box 532 to move towards the filter cake box 301. The scissor-type telescopic frame 534 inside the mounting box 532 extends, pushing the mounting plate 533 and the active gripper 535 out of the receiving cavity 512 and aligning them with the clamping port 333 on the front sealing plate 331 of the filter cake component 303. The electric latch 1 334 unlocks, the active gripper 535 clamps the clamping port 333, the scissor-type telescopic frame 534 retracts, and the filter cake component 303 containing catalyst residue is extracted into the receiving cavity 512. The active guide rail 3 531 drives the mounting box 532 to reset.

[0113] When the air-drying component 502 is activated, multiple fans 521 on the top of the receiving cavity 512 start, and at the same time, the electric heating plate 522 is energized and heats up, generating hot air to dry the filter residue 303 in the receiving cavity 512, removing residual liquid from the surface of the filter residue 303; the air inlets 523 on both sides of the carrier plate 404 are used to supplement air to ensure the air-drying effect, and the air-drying time is adjusted according to the moisture content of the residue until the filter residue is completely dry.

[0114] S3, Recycling Mode:

[0115] After the filter cake 303 is dried, the equipment enters the recycling mode. The active guide rail 202 of the conveying component 200 drives the back plate 401, bracket 402 and the loading vehicle 501 to rise and return to the mixing layer 101 through the through hole 104. The position of the loading vehicle 501 is adjusted so that the receiving cavity 512 corresponds to the recycling tank 601 of the recycling component 600, ensuring that the filter cake 303 can be smoothly pushed into the recycling tank 601.

[0116] The extraction unit 503 is activated, and the active guide rail 531 drives the mounting box 532 to move towards the recovery tank 601. The scissor-type telescopic frame 534 extends, pushing the active gripper 535 to push the dried filter cake 303 into the inlet 603 of the recovery tank 601, completing the filter cake recovery. At this time, the cleaning unit 602 is activated, and the active guide rail 621 drives the main shaft 622 and the cleaning brush 623 to move. The cleaning brush 623 cleans the catalyst residue remaining on the filter cake screen 332, ensuring that the filter cake 303 is clean.

[0117] The bottom of the recovery tank 601 is inclined. The cleaned catalyst residues are collected at the lowest point of the bottom of the recovery tank 601 under the action of gravity. The feeding auger 701 is started to transport the catalyst residues in the recovery tank 601 to the catalyst tank 114 to realize the recycling of the catalyst and reduce material waste. After completion, the components can be reset.
