Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of textile chemical preparation equipment, specifically to a reaction device for a formaldehyde-free anti-wrinkle finishing agent. Background Technology
[0002] Currently, the preparation of anti-wrinkle finishing agents for textiles mainly utilizes formaldehyde-free polycarboxylic acid-based finishing agents. The synthesis process typically involves multiple steps such as esterification and condensation, requiring strict control over reaction temperature, pressure, and impurities. Traditional reaction equipment often employs single-diameter reactors or series-connected reaction tubes, which presents the following problems:
[0003] Low reaction efficiency: A single pipe diameter cannot meet the different requirements of material flow rate and mixing degree at different reaction stages, resulting in incomplete reaction and low product yield.
[0004] Impurity removal is difficult: Solid impurities generated during the reaction process tend to adhere to the inner wall of the pipeline. Traditional vibration slag removal methods are difficult to completely remove impurities due to uneven vibration transmission or energy loss, which affects product purity and equipment lifespan.
[0005] Uneven temperature control: Conventional jacket heating or electric heating methods have problems such as heating lag and excessively high local temperatures leading to side reactions, and cannot accurately meet the reaction temperature requirements. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this invention provides a reaction apparatus for a formaldehyde-free anti-wrinkle finishing agent, thus solving the problems mentioned in the background art.
[0007] The solution of this utility model to the above-mentioned technical problems is as follows:
[0008] A reaction apparatus for a formaldehyde-free anti-wrinkle finishing agent, comprising a third reaction tube;
[0009] The third reaction tube is connected to the second reaction tube via the first reducing pipe, and the second reaction tube is connected to the first reaction tube via the second reducing pipe. A collection box is installed at the bottom end of the first and second reducing pipes, and a slag discharge pipe is provided at the bottom end of the collection box. An electromagnetic heater is installed on the outside of the third, second, and first reaction tubes, and a heating liner is installed inside the third, second, and first reaction tubes. The electromagnetic heater heats the heating liner, which is used to heat the reactants inside the third, second, and first reaction tubes. A slag removal mechanism is installed on each of the third, second, and first reaction tubes.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] Furthermore, the diameters of the third reaction tube, the second reaction tube, and the first reaction tube increase sequentially, and the first and second variable diameter tubes are tapered tubes, with the reactants flowing sequentially through the first reaction tube, the second reaction tube, and the third reaction tube.
[0012] The beneficial effects of adopting the above-mentioned further solutions are:
[0013] The combination of reaction tubes of different diameters with tapered reducing tubes allows reactants to experience varying reaction spaces and flow rates during the flow process. In the initial stage, the large-diameter first reaction tube provides ample space for thorough mixing of reactants; as the tube diameter gradually decreases, the flow rate and pressure of the reactants increase, and intermolecular collisions become more frequent, promoting a progressively deeper reaction and effectively improving reaction efficiency and degree, thus ensuring the quality of the formaldehyde-free anti-wrinkle finishing agent synthesis.
[0014] Furthermore, the collection box has a receiving cavity, and the first and second diameter reducing pipes have collection ports at corresponding positions within the receiving cavity.
[0015] The beneficial effects of adopting the above-mentioned further solutions are:
[0016] The design of the containment chamber and collection port provides a clear collection path and storage space for impurities. During the reaction, impurities that fall off under the action of the slag removal mechanism can fall directly into the containment chamber through the collection port under the action of gravity, avoiding the accumulation and residue of impurities in the reaction tube or reducing pipe diameter, ensuring the smooth flow of the reaction pipeline, reducing the interference of impurities on the reaction process and product purity, and also facilitating centralized cleaning of impurities, reducing the difficulty of equipment maintenance.
[0017] Furthermore, the slag removal mechanism includes a transmission ring, and a bracket is installed on the outside of the transmission ring, and a pulse air hammer vibrator is installed on the bracket.
[0018] The beneficial effects of adopting the above-mentioned further solutions are:
[0019] The pulsed air hammer vibrator, support frame, and transmission ring constitute a highly efficient slag removal structure. The vibration generated by the pulsed air hammer vibrator is transmitted to the transmission ring through the support frame, and the transmission ring then evenly transmits the vibration to the reaction tube, causing the reaction tube to generate high-frequency micro-vibrations. This vibration can effectively break the adhesion between impurities and the inner wall of the reaction tube, causing the impurities to fall off quickly. Compared with traditional slag removal methods, the slag removal efficiency is higher, and continuous slag removal can be achieved during the reaction process, maintaining a clean reaction environment.
[0020] Furthermore, the conductive ring is in close contact with the outer walls of the third reaction tube, the second reaction tube, and the first reaction tube.
[0021] The beneficial effects of adopting the above-mentioned further solutions are:
[0022] The conductive ring fits tightly against the outer wall of the reaction tube, minimizing losses during vibration transmission and ensuring that the vibration energy generated by the pulsed air hammer vibrator is efficiently and completely transferred to the reaction tube. Simultaneously, the tight fit design ensures uniform vibration distribution across the reaction tube surface, preventing excessively strong or weak local vibrations and guaranteeing that impurities are effectively removed from the entire inner wall of the reaction tube, thus improving the stability and comprehensiveness of the slag removal effect.
[0023] This invention provides a reaction apparatus for a formaldehyde-free anti-wrinkle finishing agent. It has the following beneficial effects:
[0024] The diameters of the third, second, and first reaction tubes increase sequentially, and they are connected by a tapered first and second reducing tube. This design allows the reactants to flow through reaction tubes of different diameters in sequence, providing different reaction spaces and flow rates according to the reaction process and the characteristics of the reactants, which is conducive to the full progress of the reaction.
[0025] An electromagnetic heater is installed on the outside of the reaction tube, and a heating liner is installed inside. The electromagnetic heater heats the heating liner, which in turn heats the reactants inside the reaction tube. This design enables uniform and efficient heating, which helps to control the reaction temperature and improve the reaction rate and product quality.
[0026] The slag removal mechanism installed on the reaction tube consists of a transmission ring, a support, and a pulsed air hammer vibrator that are closely attached to the outer wall of the reaction tube. The vibration generated by the pulsed air hammer vibrator is transmitted to the reaction tube through the transmission ring, which makes it easier for impurities inside the reaction tube to fall off, facilitating subsequent cleaning.
[0027] The collection box installed at the bottom of the first and second reducing pipes has an internal cavity. The reducing pipe has a collection port at the corresponding position in the cavity, which can effectively collect impurities generated during the reaction process, prevent impurities from accumulating in the reaction tube and affecting the reaction effect. At the same time, the slag discharge pipe at the bottom of the collection box facilitates the centralized discharge of impurities. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:
[0038] Example 1
[0039] A reaction device for a formaldehyde-free anti-wrinkle finishing agent includes a third reaction tube 1. The third reaction tube 1 is connected to a second reaction tube 3 via a first reducing pipe 2. The second reaction tube 3 is connected to a first reaction tube 7 via a second reducing pipe 4. The diameters of the third reaction tube 1, the second reaction tube 3, and the first reaction tube 7 increase sequentially. The first reducing pipe 2 and the second reducing pipe 4 are tapered tubes. The reactants flow sequentially through the first reaction tube 7, the second reaction tube 3, and the third reaction tube 1. The combination of reaction tubes of different diameters and tapered reducing pipes allows the reactants to experience different reaction spaces and flow rate changes during the flow process. In the initial stage, the large-diameter first reaction tube 7 provides ample space for thorough mixing of reactants. As the tube diameter gradually decreases, the reaction flow rate increases, the pressure rises, and intermolecular collisions become more frequent, promoting a progressively deeper reaction and effectively improving reaction efficiency and degree, thus ensuring the quality of the formaldehyde-free anti-wrinkle finishing agent synthesis. A collection box 8 is installed at the bottom of the first and second reducing tubes 2 and 4, with a slag discharge pipe 801 at the bottom of the collection box 8. Electromagnetic heaters 6 are installed on the outside of the third reaction tube 1, the second reaction tube 3, and the first reaction tube 7, and heating elements are installed inside the third reaction tube 1, the second reaction tube 3, and the first reaction tube 7. The heating liner 9 is heated by the electromagnetic heater 6. The heating liner 9 is used to heat the reactants in the third reaction tube 1, the second reaction tube 3 and the first reaction tube 7. The third reaction tube 1, the second reaction tube 3 and the first reaction tube 7 are all equipped with a slag removal mechanism 5. The slag removal mechanism 5 includes a conduction ring 503. The conduction ring 503 is in close contact with the outer wall of the third reaction tube 1, the second reaction tube 3 and the first reaction tube 7. The conduction ring 503 is in close contact with the outer wall of the reaction tube, which can minimize the loss in the vibration transmission process and ensure that the vibration energy generated by the pulse air hammer vibrator 501 is efficiently and completely transmitted to the reaction tube. Meanwhile, the tightly fitting design ensures that vibration is evenly distributed across the surface of the reaction tube, preventing excessively strong or weak local vibrations and guaranteeing that impurities can be effectively removed from the entire inner wall of the reaction tube. This improves the stability and comprehensiveness of the slag removal effect. Furthermore, a bracket 502 is installed on the outer side of the transmission ring 503, and a pulse air hammer vibrator 501 is mounted on the bracket 502. The pulse air hammer vibrator 501, the bracket 502, and the transmission ring 503 constitute a highly efficient slag removal structure. The vibration generated by the pulse air hammer vibrator 501 is transmitted to the transmission ring 503 through the bracket 502, and the transmission ring 503 then evenly transmits the vibration to the reaction tube, causing the reaction tube to generate high-frequency micro-vibrations. This vibration effectively breaks the adhesion between impurities and the inner wall of the reaction tube, allowing impurities to fall off quickly. Compared to traditional slag removal methods, this method has higher slag removal efficiency and enables continuous slag removal during the reaction process, maintaining a clean reaction environment.
[0040] Example 2
[0041] To more effectively collect and process impurities generated during the reaction process and avoid their adverse effects on the reaction, for example, such as Figures 1 to 4As shown, this utility model also includes: a receiving cavity 802 is provided inside the collection box 8, and a collection port 201 is provided at the corresponding position of the first reducing pipe 2 and the second reducing pipe 4 within the receiving cavity 802. The design of the receiving cavity 802 and the collection port 201 provides a clear collection path and storage space for impurities. During the reaction process, impurities that fall off under the action of the slag removal mechanism 5 can fall directly into the receiving cavity 802 through the collection port 201 under the action of gravity, avoiding the accumulation and residue of impurities in the reaction tube or reducing pipe, ensuring unobstructed reaction pipeline, reducing the interference of impurities on the reaction process and product purity, and also facilitating centralized cleaning of impurities, reducing the difficulty of equipment maintenance.
[0042] Working principle:
[0043] The reactants first flow into the largest diameter first reaction tube. The spacious interior provides an initial mixing and reaction environment, allowing the reactants to begin reacting in a relatively relaxed space. At this time, an electromagnetic heater heats the heating lining installed inside the first reaction tube. The heating lining transfers heat to the reactants inside the tube. By precisely controlling the power of the electromagnetic heater, the reaction temperature can be maintained within a suitable range, promoting the reaction.
[0044] After the initial reaction in the first reaction tube, the reactants enter the slightly smaller-diameter second reaction tube through a tapered reducer. The tapered structure of the reducer helps guide the reactants through a smooth transition, and as the tube diameter decreases, the flow rate and pressure of the reactants change, resulting in more thorough contact between the reactants and further promoting the reaction. Inside the second reaction tube, an electromagnetic heater continuously heats the reactants through a heating liner to maintain the required reaction temperature.
[0045] The reactants, after further reaction in the second reaction tube, flow again through the tapered reducing tube into the third reaction tube, which has the smallest diameter. Here, the reactants flow faster within the smaller tube diameter, increasing the collision frequency between reactant molecules and promoting a faster and more complete reaction. The heating lining inside the third reaction tube, powered by an electromagnetic heater, continuously provides heat to sustain the reaction.
[0046] Throughout the reaction process, the slag removal mechanism installed on the reaction tube operates continuously. A pulsed air hammer vibrator is mounted on a support, which is tightly attached to the outer wall of the reaction tube via a transmission ring. The pulsed air hammer vibrator periodically generates vibrations, which are transmitted to the reaction tube through the transmission ring, causing the tube to vibrate slightly and prompting impurities adhering to the inner wall of the reaction tube to detach.
[0047] Under the influence of gravity, the detached impurities fall into the collection box cavity below through the collection ports on the first and second reducing pipes. When the impurities in the collection box accumulate to a certain amount, they can be discharged through the slag discharge pipe at the bottom of the collection box, ensuring the cleanliness of the reaction equipment and preventing impurities from affecting the reaction effect and product quality.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
