Description

Technical Field

[0001] This utility model relates to the field of nylon production technology, and in particular to a transparent nylon production neutralization reactor. Background Technology

[0002] In modern industrial production, nylon materials are widely used in many fields such as automobile manufacturing, electronic equipment, and textiles and clothing due to their excellent mechanical properties, wear resistance, and chemical corrosion resistance. Among them, transparent nylon is highly favored in industries with special requirements for transparency, such as optical instruments and packaging materials, because of its good optical properties.

[0003] Currently, with the continuous advancement of industrial technology, the design and manufacturing technology of reaction vessels has also made certain progress. Some reaction vessels have basic stirring and heating functions, enabling preliminary control of reaction temperature and material mixing degree. At the same time, some reaction vessels have been optimized in structure, such as increasing the number and layout of feed inlets and outlets to improve material feeding and discharging efficiency.

[0004] However, existing neutralization reactors for transparent nylon production still have many shortcomings. In terms of temperature control, traditional reactors mostly use a single heating or cooling method, which makes it difficult to accurately control temperature changes during the reaction process. The neutralization reaction of transparent nylon is quite sensitive to temperature, and temperature fluctuations may lead to incomplete reactions or side reactions, affecting the quality and purity of the product. In terms of material stirring, common stirring devices have poor stirring effects and cannot ensure that the materials are fully mixed in the reactor, thus affecting the uniformity and stability of the reaction. This also limits the efficiency and quality of transparent nylon production to some extent. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a transparent nylon production neutralization reactor, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a transparent nylon production neutralization reactor, including...

[0008] The vessel body has a main feed inlet, a stirring mechanism and a batching box at the top, a raw material outlet at the bottom, and a heating chamber surrounding the outer wall of the vessel body.

[0009] A spiral heating coil is installed inside the heating chamber;

[0010] The stirring mechanism includes a stirring motor, a main shaft, and fan blades. The stirring motor is fixedly installed on the top of the vessel and the output shaft of the stirring motor extends vertically downward.

[0011] The main shaft runs through the top of the vessel and is coaxially connected to the output shaft of the stirring motor. Fan blades and heat storage rods are installed at intervals on the main shaft, and the heat storage rods are filled with phase change energy storage material.

[0012] Furthermore, the fan blades consist of three layers of staggered blades, with scrapers connected to the ends of the blades via centrifugal springs.

[0013] Furthermore, heat transfer wires are embedded inside the blades, extending into the heat capacity rods and contacting the phase change energy storage material. Heat exchange grooves are provided on the blade surface, and these grooves are wavy and distributed radially along the blade.

[0014] Furthermore, the batching box is connected to the main feed inlet via a batching pipe, and multiple partition plates are installed inside the batching box.

[0015] Furthermore, multiple partitions divide the material box into multiple storage bins, and each material dispensing pipe is equipped with a dispensing valve in the middle.

[0016] Furthermore, the top of the mixing box is equipped with a sealing cover, which is fixedly connected to the mixing box by a snap fastener.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model is equipped with a temperature control structure that combines a heating chamber and a heat storage rod filled with phase change energy storage material, which can improve the accuracy of temperature control. The spiral heating coil in the heating chamber provides basic heating. When the temperature is too high, the phase change energy storage material in the heat storage rod absorbs heat and stores heat in a phase change. When the temperature is low, it releases heat, such as the neutralization reaction of transparent nylon. When releasing heat, it absorbs excess heat to prevent side reactions. When absorbing heat, it replenishes heat to stabilize the reaction, thereby improving product quality and purity.

[0019] 2. This utility model is equipped with a stirring assembly with three layers of staggered blades and a scraper, which enhances the stirring and cleaning effect. The three layers of staggered blades expand the stirring range, so that the materials are fully mixed and the reaction is stable. The scraper at the end of the blades extends out of the wall under centrifugal force as the rotation speed increases, preventing the material from adhering and scaling, allowing the material on the reactor wall to participate in the reaction again, improving efficiency and solving the traditional stirring and cleaning problems.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] Reference Figure 1-3 This is the first embodiment of the present invention, which provides a neutralization reactor for the production of transparent nylon, including a reactor body 1. The top of the reactor body 1 is provided with a main feed inlet 13, a stirring mechanism 3 and a batching box 2. The bottom of the reactor body 1 is provided with a raw material outlet 14. A heating chamber 12 is arranged around the outer wall of the reactor body 1. A spiral heating coil 121 is installed in the heating chamber 12. The heating coil 121 generates heat through current to heat the reactants in the reactor body 1, thereby meeting the temperature requirements of the neutralization reaction of transparent nylon.

[0031] The stirring mechanism 3 includes a stirring motor 31, a main shaft 32, and fan blades 33. The stirring motor 31 is fixedly installed on the top of the vessel body 1 and its output shaft extends vertically downward to provide power for the stirring process and drive the main shaft 32 to rotate. The main shaft 32 passes through the top of the vessel body 1 and is coaxially connected to the output shaft of the stirring motor 31. Fan blades 33 and heat storage rods 321 are installed on the main shaft 32 at intervals. The heat storage rods 321 are filled with phase change energy storage material, which stabilizes the reaction environment temperature by absorbing or releasing heat when the reaction temperature changes.

[0032] The fan blade 33 contains three layers of staggered blades. This layout expands the stirring range, allowing the materials in the vessel 1 to be mixed more thoroughly and promoting the uniform neutralization reaction of the transparent nylon. The blade ends are connected to scrapers 332 via centrifugal springs 334. When the stirring motor 31 drives the main shaft 32 to increase its speed, the scrapers 332 extend under the action of centrifugal force, overcoming the elastic force of the centrifugal springs 334, and can effectively scrape the inner wall of the vessel 1 to prevent the material from adhering and scaling.

[0033] The blade is embedded with a heat transfer wire 333, which extends into the heat capacity rod 321 and contacts the phase change energy storage material. This design can transfer the heat of the phase change energy storage material in the heat capacity rod 321 to the blade, realizing a wider heat transfer in the reactor and helping to maintain the temperature balance of the reaction system. The blade surface is provided with heat exchange grooves 331, which are wavy and distributed radially along the blade, increasing the contact area between the blade and the material, accelerating the heat exchange rate, and enabling the material to absorb or release heat more efficiently, thereby improving the reaction efficiency and stability.

[0034] Example 2

[0035] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0036] The mixing tank 2 is connected to the main feed inlet 13 via the mixing pipe 23, providing the reactor with various raw materials. The mixing tank 2 is divided into multiple storage bins 211 by the partition plate 21. Each storage bin 211 can store different raw materials separately, realizing the classified storage of various raw materials and avoiding cross-contamination or premature reaction between raw materials. Each mixing pipe 23 is equipped with a mixing valve 231 in the middle. By controlling the opening degree and time of the mixing valve 231, the feed amount and feeding time of the raw materials in each storage bin 211 can be precisely controlled, meeting the requirements of precise proportion of different raw materials in the neutralization reaction during the production of transparent nylon, ensuring the smooth progress of the reaction, and thus improving product quality.

[0037] The operator can control the stirring mechanism 3 to stir the materials; and can also control the opening and closing status and size of the batching valve 231 to precisely adjust the flow rate and time of the raw materials delivered from each storage bin 211 in the batching box 2 to the reactor, thereby improving the level of automation and production efficiency.

[0038] The top of the mixing box 2 is equipped with a sealing cover 22, which is fixedly connected to the mixing box 2 by a snap fastener. The sealing cover 22 can effectively prevent external dust, impurities and other contaminants from entering the mixing box 2 and avoid contaminating the raw materials stored in the mixing box 2.

[0039] The remaining structure is the same as that in Example 1.

[0040] The specific operating principle of this utility model is as follows:

[0041] First, according to the formula requirements for the neutralization reaction in the production of transparent nylon, the operator opens the sealing cover 22 on the top of the mixing box 2 and adds different raw materials to the corresponding storage bins 211. Then, the sealing cover 22 is closed and the stirring motor 31 is turned on. The stirring motor 31 drives the main shaft 32 to rotate, and the fan blades 33 and heat capacity rods 321 installed at intervals on the main shaft 32 rotate accordingly. At the same time, according to the required temperature of the reaction, the spiral heating coil 121 in the heating chamber 12 is controlled to heat the material in the reactor 1. The heating chamber 12 initially raises the temperature of the material in the reactor 1.

[0042] Secondly, during the stirring process, the three layers of staggered blades of the fan blade 33 thoroughly stir the material, making the material evenly mixed. As the rotation speed of the main shaft 32 increases, the scraper 332 connected to the end of the blade through the centrifugal spring 334 extends under centrifugal force and scrapes the inner wall of the vessel 1 to prevent the material from adhering and scaling. The heat transfer wire 333 embedded in the blade transfers the heat of the phase change energy storage material in the heat capacity rod 321 to the blade. The wavy heat exchange groove 331 on the surface of the blade increases the contact area with the material and accelerates heat exchange. When the reaction temperature fluctuates, the phase change energy storage material in the heat capacity rod 321 absorbs or releases heat to stabilize the reaction temperature. In addition, the opening and closing of the batching valve 231 allows the raw materials in different storage bins 211 in the batching box 2 to enter the vessel 1 from the main feed port 13 through the batching pipe 23 to participate in the reaction.

[0043] Finally, after the reaction is complete, turn off the stirring motor 31, heating coil 121 and feeding valve 231, and open the raw material outlet 14 at the bottom of the vessel 1 to discharge the reaction product.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
