Description

Technical Field

[0001] This utility model relates to the technical field of reaction vessel cleaning equipment, specifically to an automatic reaction vessel cleaning device. Background Technology

[0002] Automatic cleaning devices for reaction vessels are key auxiliary equipment in industries such as chemical, pharmaceutical, food, and new materials. Their core function is to replace manual labor in cleaning residual materials, scale, and contaminants from the inner walls of containers such as reaction kettles, polymerization kettles, and mixing tanks. They can ensure cleaning efficiency and cleanliness while avoiding the safety risks of manual cleaning, and at the same time meet industry compliance requirements.

[0003] Chinese Patent Announcement No. CN216458847U discloses a high-performance polycarboxylate superplasticizer reactor. This design utilizes a drive motor to rotate an active stirring shaft. The main stirring rod on the active stirring shaft stirs the raw materials within the reactor. The rotation of the active stirring shaft also drives the rotation of the drive and driven gears, simultaneously stirring the auxiliary stirring rods on two auxiliary stirring shafts. This results in high stirring efficiency and promotes uniform mixing of the raw materials. A water pump is included to inject mixed water into the reactor and to facilitate the injection of clean water during the cleaning of the reactor's inner wall. A connecting rod allows the active stirring shaft to drive a scraper to clean the reactor's inner wall during rotation. A ladder facilitates maintenance and other operations for workers, and safety railings ensure worker safety.

[0004] However, the following defects still exist in the specific implementation process: after polycarboxylic acid residues agglomerate, it is difficult to destroy their agglomeration structure by simply using high-pressure jet or chemical cleaning solution, resulting in trace residues after cleaning, which affects the quality of the next batch of products.

[0005] Based on this, the present invention designs an automatic cleaning device for reaction vessels to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic cleaning device for reaction vessels.

[0007] To achieve the above objectives, this utility model provides the following technical solution: An automatic cleaning device for a reaction vessel includes a reaction vessel. Support legs are fixedly connected to all four sides of the lower end of the reaction vessel. A storage tank filled with a dispersing agent is fixedly installed at the upper end of the reaction vessel. A motor is fixedly connected to the middle of the upper end of the storage tank. A transmission rod is fixedly connected to the output end of the motor. A rotating hole matching the transmission rod is opened in the middle of the storage tank. Multiple sets of heating rods are fixedly connected to all four sides of the outer end of the transmission rod. Scrapers are fixedly connected to the ends of the heating rods away from the transmission rod, and the scrapers are in close contact with the inner wall of the reaction vessel. A [missing information - likely a device or component] is fixedly connected to the end of the scraper near the transmission rod. A push plate is positioned above the heating rod. Multiple retractable rods corresponding to the push plate are installed inside the storage tank. A motor drives a transmission rod to cause multiple sets of heating rods to drive multiple scrapers to scrape and clean the inner wall of the reactor. The push plate's movement causes the retractable rods to extend and retract, spraying the dispersant from the storage tank. This disperses and prevents agglomeration of polycarboxylic acid residues in the reactor, dissolves and breaks down adhesion, and assists in peeling, thus better cleaning the reactor. Simultaneously, the heating rods enhance the activity of the additives, weaken residual adhesion, and optimize the flowability of the cleaning solution, further improving the cleaning effect. Furthermore, the pusher includes a load-bearing rod, which is fixedly connected to the end of the scraper near the transmission rod. A first magnet is fixedly connected to the end of the load-bearing rod away from the scraper. A protrusion is fixedly connected to the upper end of the first magnet. The magnetic force of the first magnet repels the retracting rod, causing it to contract and sprinkle the dispersing agent, which falls onto the upper end of the protrusion. The convex surface of the protrusion helps to evenly disperse the agent into the reaction vessel. Furthermore, the retractable rod includes a storage cylinder, which is fixedly connected to the inner wall of the storage tank. An extension rod is slidably connected to the middle of the storage cylinder, and a stopper is fixedly connected to the lower end of the extension rod. A discharge hole matching the stopper is opened at the lower end of the storage tank. A second magnet is fixedly connected to the lower end of the stopper. When the first magnet moves to the lower end of the retractable rod, the magnetic force between the first magnet and the second magnet generates repulsion, causing the extension rod to slide and retract into the storage cylinder. The stopper then disengages from the discharge hole, allowing the dispersing agent to be discharged. After the repulsion between the second magnet and the first magnet is lost, the stopper is re-engaged into the discharge hole under the weight of the stopper and the extension rod, as well as under the pressure of the liquid, to prevent excessive discharge of the dispersing agent. Furthermore, the extension rod also includes a return spring, which is fixedly connected between the extension rod and the inner wall of the liquid storage tank. The return spring can assist in pushing the plug to block the discharge hole when the extension rod and the plug are misaligned and lose their repulsive force. Furthermore, the retractable rod also includes a sealing gasket, which is fixedly connected to the outer end of the plug and the second magnet. The sealing gasket can enhance the sealing between the plug and the discharge hole, reducing the leakage and loss of the dispersing agent. Furthermore, the retractable rod also includes a stop rod. The upper end of the liquid storage tank has a sliding hole, and the stop rod is slidably connected in the sliding hole. The stop rod is located in the middle of the return spring. A screw block is fixedly connected to the upper end of the stop rod, and the screw block is threadedly connected to the sliding hole. After the screw block is tightened, the stop rod abuts against the extension rod. In this way, when not cleaned, the first magnet can be prevented from repelling and pushing the second magnet, and the discharge hole can be prevented from being opened unintentionally. Furthermore, the extension rod also includes a sealing ring, which is fixedly connected to the lower end of the storage tube and located at the outer end of the extension rod and fits against it. The sealing ring can seal the gap between the extension rod and the storage tube, reducing liquid seepage into the storage tube. Furthermore, a cross plate is fixedly connected to the lower end of each of the scrapers, and the cross plate is in close contact with the lower inner wall of the reactor. The lower inner wall of the reactor can be scraped and cleaned through the cross plate.

[0008] (1) This solution significantly improves the peeling efficiency of polycarboxylic acid residues through the synergistic effect of mechanical scraping and dispersing agent. The motor drives the scraper to rotate against the inner wall of the reactor to directly and physically scrape off the high-viscosity adhesive layer. With the magnetic linkage structure of the push plate and the release rod, the dispersing agent in the storage tank can be released as needed, thereby effectively improving the cleaning efficiency.

[0009] (2) This solution releases heat evenly as the heating rod rotates with the scraper, which not only enhances the molecular activity of the dispersing agent, allowing it to penetrate the residue more quickly and fully exert its dispersing effect, but also weakens the intermolecular forces of the polycarboxylic acid residue and reduces its adhesion strength to the reactor wall. At the same time, the flowability of the cleaning system after heating is improved, which can carry the dispersed fine particles out quickly and further shorten the cleaning cycle.

[0010] (3) This solution ensures that the dispersing agent is released as needed and avoids excessive waste by using components such as the return spring of the release rod, sealing gasket and sealing ring. It also enhances the sealing of the storage tank and reduces the leakage of the agent. The cross plate eliminates the cleaning dead corners by simultaneously cleaning the bottom of the reactor. At the same time, the cooperation between the push rod and the screw block can lock the discharge hole in the non-cleaning state to prevent misoperation. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] In some embodiments, please refer to the appendix to the instruction manual. Figures 1-5An automatic cleaning device for a reaction vessel includes a reaction vessel 1. Support legs 2 are fixedly connected to the lower perimeter of the reaction vessel 1. A storage tank 3 is fixedly installed on the upper end of the reaction vessel 1, and the storage tank 3 is filled with a dispersing agent. A motor 4 is fixedly connected to the middle of the upper end of the storage tank 3. A transmission rod 5 is fixedly connected to the output end of the motor 4. A rotating hole matching the transmission rod 5 is opened in the middle of the storage tank 3. Multiple sets of heating rods 6 are fixedly connected to the outer perimeter of the transmission rod 5. Scrapers 7 are fixedly connected to the ends of the heating rods 6 away from the transmission rod 5, and the scrapers 7 are in close contact with the inner wall of the reaction vessel 1. A push plate 8 is fixedly connected to the end of the scraper 7 near the transmission rod 5, and the push plate 8 is located above the heating rods 6. Multiple retractable rods 9 corresponding to the push plates 8 are installed inside the storage tank 3. The support legs 2 at the lower end of the reactor 1 provide stable support for the reactor 1, facilitating smooth cleaning operations. The storage tank 3 at the upper end of the reactor 1 can properly store dispersing agents, providing material support for cleaning. The motor 4 drives the transmission rod 5 to rotate, which in turn drives multiple sets of heating rods 6 and scrapers 7. The scrapers 7 are in contact with the inner wall of the reactor 1, which can scrape off the polycarboxylic acid residue adhesive layer on the inner wall of the reactor. The heating rods 6 release heat during operation, which helps to enhance the activity of the dispersing agents and weaken the residual adhesive force. The push plate 8 and the retracting rod 9 work together to realize the release of dispersing agents as needed. The overall structure forms a synergistic effect of mechanical scraping, heating assistance and agent dispersion, which helps to improve the cleaning effect of polycarboxylic acid residue in the reactor 1. The push plate 8 includes a load-bearing rod 81, which is fixedly connected to the end of the scraper 7 near the transmission rod 5. A first magnet 82 is fixedly connected to the end of the load-bearing rod 81 away from the scraper 7. A protrusion 83 is fixedly connected to the upper end of the first magnet 82. By pushing the plate 8, the load-bearing rod 81 can stably connect the scraper 7 and the first magnet 82, ensuring the stability of the push plate 8 moving synchronously with the scraper 7. The first magnet 82 can form a magnetic interaction with the retracting rod 9, providing a trigger condition for the release of the dispersing agent. The protrusion 83 at the upper end of the first magnet 82 can receive the dispersing agent discharged from the storage tank 3. By using its own convex surface, the dispersing agent is evenly dispersed, which facilitates the dispersing agent to fully contact the polycarboxylic acid residue in the reaction vessel 1, helping to improve the effect of the dispersing agent. The retractable rod 9 includes a storage cylinder 91, which is fixedly connected to the inner wall of the liquid storage tank 3. An extension rod 92 is slidably connected in the middle of the storage cylinder 91. A stopper 93 is fixedly connected to the lower end of the extension rod 92. The lower end of the liquid storage tank 3 has a discharge hole that matches the stopper 93. A second magnet 94 is fixedly connected to the lower end of the stopper 93. The storage cylinder 91 can limit and store the extension rod 92. The extension rod 92 drives the stopper 93 to cooperate with the discharge hole of the liquid storage tank 3, which can control the opening and closing of the discharge hole. The second magnet 94 at the lower end of the stopper 93 can generate a magnetic repulsion with the first magnet 82 of the push plate 8, causing the extension rod 92 to retract and the stopper 93 to disengage from the discharge hole, thereby realizing the discharge of the dispersing agent. When the magnetic repulsion disappears, the stopper 93 can be reset to seal the discharge hole, which helps to realize the on-demand release of the dispersing agent and reduce the unnecessary loss of the agent. The retractable rod 9 also includes a return spring 95, which is fixedly connected between the extension rod 92 and the inner wall of the storage tank 3. When the first magnet 82 and the second magnet 94 lose their repulsive force, the return spring 95 can generate an elastic force to help push the extension rod 92 to drive the plug 93 to reset quickly, so that the plug 93 can be inserted into the discharge hole in time, making the sealing of the discharge hole more timely and further improving the controllability of the dispersant release. The retractable rod 9 also includes a sealing gasket 96, which is fixedly connected to the outer end of the plug 93 and the second magnet 94. By fixing the plug 93 and the second magnet 94 to the outer end of the sealing gasket 96 on the retractable rod 9, the tightness of the fit between the plug 93 and the discharge hole of the liquid storage tank 3 can be enhanced, reducing the leakage of the dispersing agent from the gap in the sealed state, reducing the loss of the dispersing agent, and ensuring the sealing performance of the liquid storage tank 3. The retractable rod 9 also includes a stop rod 97. The upper end of the liquid storage tank 3 has a sliding hole. The stop rod 97 is slidably connected in the sliding hole and is located in the middle of the return spring 95. A screw block 98 is fixedly connected to the upper end of the stop rod 97 and is threadedly connected to the sliding hole. The stop rod 97 in the retractable rod 9 is slidably connected in the sliding hole of the liquid storage tank 3 and is located in the middle of the return spring 95. The screw block 98 is threadedly connected to the sliding hole. Tightening the screw block 98 can drive the stop rod 97 to abut against the extension rod 92. When the device is not performing cleaning operations, it can restrict the sliding of the extension rod 92, prevent the first magnet 82 from accidentally repelling the second magnet 94 and causing the discharge hole to open accidentally, and improve the stability of the device when it is idle. The retractable rod 9 also includes a sealing ring 99, which is fixedly connected to the lower end of the storage cylinder 91. The sealing ring 99 is located at the outer end of the extension rod 92 and is fitted to it. By fixing the sealing ring 99 in the retractable rod 9 to the lower end of the storage cylinder 91 and fitting it to the extension rod 92, the gap between the storage cylinder 91 and the extension rod 92 can be sealed, reducing the seepage of the dispersing agent in the liquid storage tank 3 into the interior of the storage cylinder 91. This can not only avoid the waste of the agent, but also prevent the agent residue from affecting the internal structure of the storage cylinder 91, and ensure the smooth sliding of the extension rod 92. Multiple scrapers 7 are fixedly connected to cross plates 10 at their lower ends, and the cross plates 10 are in close contact with the lower inner wall of the reactor 1. Through the cross plates 10 connected to the lower ends of the multiple scrapers 7 in close contact with the lower inner wall of the reactor 1, the cross plates 10 can rotate synchronously when the scrapers 7 rotate with the transmission rod 5, so as to scrape off the polycarboxylic acid residues attached to the lower inner wall of the reactor 1. This can reduce the cleaning dead corners at the bottom of the reactor 1, make the cleaning range inside the reactor 1 more comprehensive, and help improve the overall cleaning quality of the reactor 1 by the device.

[0017] It should be noted that the specific installation methods of the motor 4 and the heating rod 6, the circuit connection methods, and the control methods in this utility model are all conventional designs, and will not be described in detail in this utility model. Working principle: Before the cleaning operation begins, loosen the screw block 98 connected to the push rod 97 on the liquid storage tank 3 to release the limit of the push rod 97 on the extension rod 92. At this time, the plug block 93 of the retracting rod 9 is locked at the discharge hole under the force of the return spring 95, its own weight, and the compression of the dispersing agent in the liquid storage tank 3. The sealing gasket 96 enhances the sealing between the plug block 93 and the discharge hole, and the sealing ring 99 at the lower end of the storage cylinder 91 seals the gap between the storage cylinder 91 and the extension rod 92 to prevent the dispersing agent from leaking. After starting the motor 4, the output end of the motor 4 drives the transmission rod 5 along the liquid storage tank 3. As the rotating hole rotates, the transmission rod 5 synchronously drives the multiple sets of heating rods 6 around it and the scraper 7 connected to the heating rods 6 to rotate. The scraper 7 rotates against the inner wall of the reactor 1 to scrape off the polycarboxylic acid residue adhesive layer on the reactor wall. At the same time, the scraper 7 drives the push plate 8 to rotate together. During the operation of the heating rods 6, heat is released to increase the temperature inside the reactor 1, which helps to enhance the activity of the dispersing agent and weaken the adhesive force of the polycarboxylic acid residue. When the push plate 8 rotates to the position corresponding to the take-up and release rod 9, the first magnet 82 connected to the load-bearing rod 81 in the push plate 8 and the lower end of the plug 93 in the take-up and release rod 9... The second magnet 94 generates a magnetic repulsion, pushing the extension rod 92 to retract into the receiving cylinder 91, thereby causing the stopper 93 to disengage from the discharge hole. The dispersing agent in the storage tank 3 is discharged from the discharge hole and falls onto the protrusion 83 on the upper end of the first magnet 82. After being evenly dispersed by the convex surface of the protrusion 83, it fully contacts the polycarboxylic acid residue in the reaction vessel 1, achieving dispersion and preventing agglomeration of the residue. When the push plate 8 rotates away from the corresponding position of the receiving rod 9 along with the scraper 7, the magnetic repulsion between the first magnet 82 and the second magnet 94 disappears, and the return spring 95 becomes elastic. The force-assisted extension rod 92 drives the plug block 93 to quickly reset and re-seal the discharge hole to achieve the release of the dispersing agent as needed. At the same time, the cross plate 10 at the lower end of the scraper 7 rotates synchronously with the scraper 7, adhering to the inner wall of the reactor 1 to scrape off the polycarboxylic acid residue at the bottom. The whole process is driven by the motor 4 to achieve the coordinated action of mechanical scraping, heating assistance and dispersing agent release, and complete the comprehensive cleaning of the polycarboxylic acid residue inside the reactor 1. The support leg 2 at the lower end of the reactor 1 provides stable support for the reactor 1 throughout the process, ensuring that the entire cleaning process is carried out smoothly.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
