Description

Technical Field

[0001] This utility model relates to the field of nylon production equipment technology, and more specifically to a nylon polymerization production apparatus. Background Technology

[0002] As a key member of the polymer material field, the mixing device plays a crucial role in the polymerization process of nylon. It bears the heavy responsibility of ensuring thorough and uniform mixing of raw materials, laying the foundation for the smooth progress of the polymerization reaction, and is one of the key factors determining product quality and production efficiency. However, current nylon polymerization mixing devices generally suffer from simple and rudimentary structures, especially lacking effective efficiency-enhancing mechanisms. In traditional models, the mixing task is mainly accomplished by the rotation of basic stirring blades. This method is too simplistic and inefficient, resulting in low mixing efficiency and failing to meet the demands of high-efficiency production. Therefore, it is necessary to improve existing nylon polymerization mixing devices to enhance their mixing efficiency and production performance. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a nylon polymerization production apparatus to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a nylon polymerization production apparatus, comprising a main body, the main body comprising:

[0005] The reaction vessel has a feed inlet at the top and a discharge outlet at the bottom.

The mounting box is connected to the mounting rod, the driving bevel gear and the driven bevel gear by bearings to ensure flexible rotation. The bearings are equipped with a double sealing assembly, including a mechanical seal and an oil seal, to prevent material leakage into the mounting box and affecting the gear transmission.

[0008] An electric motor, mounted on top of the reaction vessel, is used to drive the mounting rod to rotate.

[0009] Furthermore, the reaction vessel adopts a split structure, including a vessel body and a cover, which are connected by bolts. A sealing gasket is provided at the connection surface between the vessel body and the cover to ensure the sealing performance of the reaction vessel.

[0010] Furthermore, a filter is connected to the feed inlet. The filter has a multi-layer filter structure, including a coarse filter, a fine filter, and an activated carbon adsorption layer.

Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] Example 1: The core component of the nylon polymerization production apparatus involved in this utility model is the main body 100 of the apparatus, and its specific structure is as follows:

[0025] Reaction vessel 110:

[0026] The reaction vessel 110 is equipped with a feed inlet 112 at the top and a discharge outlet 123 at the bottom. This reaction vessel adopts a unique double-layer structure design. The inner layer is made of corrosion-resistant alloy material, which directly contacts the reactants and effectively resists their corrosive effects. The outer layer uses heat-insulating material. This design significantly reduces heat loss, creating and maintaining a stable and suitable temperature environment for the reaction, ensuring the high efficiency and stability of the reaction process.

[0027] Stirring mechanism:

[0028] The stirring mechanism is installed inside the reaction vessel 110 and mainly consists of a mounting rod 114, stirring blades 115, and efficiency-enhancing components. The mounting rod 114 is precisely and vertically installed at the center of the reaction vessel 110, and the stirring blades 115 are firmly fixed to the mounting rod 114 to achieve basic stirring of the materials.

[0029] The efficiency-enhancing component is a key innovative part of the mixing mechanism. It includes a driving bevel gear 116 fixedly mounted on a mounting rod 114. The driving bevel gear 116 meshes with four driven bevel gears 117 to form a highly efficient transmission system. A transverse connecting rod 118 is fixedly connected to the central shaft of each driven bevel gear 117. Multiple baffles 119 are evenly distributed along the length of the connecting rod 118. When the mixing mechanism is running, the driving bevel gear 116 drives the driven bevel gears 117 to rotate, which in turn causes the connecting rod 118 and its baffles 119 to rotate synchronously. The baffles 119 can effectively disrupt the flow state of the material, enhance the mixing effect, and improve the uniformity and efficiency of the reaction.

[0030] Installation box 120:

[0031] The mounting box 120 covers the exterior of the driving bevel gear 116 and the driven bevel gear 117. The connections between the mounting box 120 and the mounting rod 114, driving bevel gear 116, and driven bevel gear 117 are all made using bearings. This design ensures the flexibility of each component during rotation and reduces frictional resistance. Simultaneously, a double sealing assembly, combining mechanical and oil seals, is specially installed at the bearings to strictly prevent material leakage into the mounting box 120, avoiding damage to the gear transmission system or affecting its normal operation, thereby ensuring the stable operation of the entire stirring mechanism.

[0032] Motor 113:

[0033] The motor 113 is installed on the top of the reaction vessel 110. Its main function is to provide rotational power to the mounting rod 114, drive the stirring mechanism to run continuously, and thus drive the materials in the reaction vessel 110 to be fully stirred and mixed, ensuring the smooth progress of the reaction.

[0034] Example 2:

[0035] Example 2 is a further optimization and improvement based on Example 1. The specific differences are as follows:

[0036] Reaction vessel structure:

[0037] The reaction vessel 110 adopts a split structure, consisting of a vessel body and a cover 111, which are connected by bolts 121. This connection method facilitates the installation, disassembly, and maintenance of the reaction vessel. A sealing gasket is carefully installed at the connection surface between the vessel body and the cover 111. This effectively ensures the overall sealing performance of the reaction vessel 110, preventing material leakage and the entry of external impurities into the reaction vessel during the reaction process, thus ensuring the purity and stability of the reaction environment.

[0038] Inlet filter device:

[0039] A specially designed filter 122 is connected to the feed inlet 112. This filter employs a multi-layer filter structure, specifically including a coarse filter, a fine filter, and an activated carbon adsorption layer. This structural design can efficiently filter various impurities and particles in the raw materials, while utilizing the properties of the activated carbon adsorption layer to adsorb some harmful gases and odors, thereby ensuring the high purity of the raw materials entering the reaction tank 110 and guaranteeing a high-quality nylon polymerization reaction. Furthermore, the filter 122 is detachably connected to the feed inlet 112, allowing operators to easily clean and replace the filter regularly, ensuring long-term effective operation and reducing maintenance costs.

[0040] Reactor inner wall treatment and baffle optimization:

[0041] The inner wall of reaction vessel 110 undergoes a fine polishing process. This treatment significantly reduces material adhesion to the vessel wall, facilitating post-reaction cleaning, reducing material residue, and improving reaction efficiency while lowering production costs. The baffle 119 features a wave-shaped design, which, compared to ordinary baffles, generates a stronger turbulence effect during rotation, promoting multi-dimensional mixing of materials within the reaction vessel, further enhancing mixing uniformity and facilitating a more complete reaction. The baffle 119 is made of high-strength engineering plastic, which possesses excellent corrosion resistance and wear resistance, maintaining good performance over long-term use. Its lightweight nature also reduces energy consumption and improves energy efficiency during rotation.

[0042] Motor speed control function:

[0043] Motor 113 uses a variable frequency speed control motor, which has the advantage of flexibly adjusting the stirring speed according to different reaction stages and material characteristics. In the initial stage of the reaction, when the material concentration is low and the reaction is relatively mild, the stirring speed can be appropriately reduced to avoid excessive stirring causing material splashing and energy waste. In the middle and later stages of the reaction, as the material concentration increases and the reaction intensifies, the stirring speed can be increased accordingly to ensure that the materials are fully mixed and the reaction proceeds quickly and uniformly, thereby improving the quality and efficiency of the entire nylon polymerization production process, while also reducing production costs and energy consumption.
