Description

Technical Field

[0001] This utility model relates to the field of chlorinated paraffin preparation technology, specifically to a chlorinated paraffin reaction apparatus. Background Technology

[0002] Chlorinated paraffin is a compound produced by a substitution reaction between paraffin and chlorine under specific conditions. In this process, hydrogen atoms in the paraffin are partially or completely replaced by chlorine atoms, resulting in chlorinated paraffin molecules containing varying numbers of chlorine atoms. This reaction is a free radical substitution reaction. Chlorine gas generates chlorine free radicals under conditions such as light, heat, or initiators. These chlorine free radicals combine with hydrogen atoms in the paraffin molecules, causing the hydrogen atoms to be replaced, forming chlorinated paraffin and hydrogen chloride.

[0003] If chlorine and paraffin are not thoroughly mixed, they may not come into sufficient contact in certain areas of the reactor, resulting in a slower reaction rate. Normally, if chlorine and paraffin are thoroughly mixed, the reaction can be completed in a short time. However, insufficient mixing requires a longer reaction time to reach the desired extent, reducing production efficiency and potentially increasing energy consumption and equipment wear, thus affecting reaction results and product quality. Uneven reaction can also lead to localized over- or under-reaction, resulting in inconsistent chlorinated paraffin composition in the product. In some areas, excessive chlorine may produce over-chlorinated paraffin with a high chlorine content; while in other areas, insufficient chlorine may result in lower chlorine content, leading to inconsistent product quality. Therefore, we propose a chlorinated paraffin reaction apparatus. Utility Model Content

[0020] 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 embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figures 1-3 As shown, this embodiment provides a chlorinated paraffin reaction apparatus, including a mounting bracket 100. Considering that if chlorine and paraffin cannot be fully mixed, resulting in insufficient contact between paraffin and chlorine in certain areas of the reactor, the insufficient contact between reactants slows down the reaction rate. Uneven reaction may also lead to local over-reaction or under-reaction, which will cause inconsistent chlorinated paraffin composition in the product. Therefore, specifically: a processing tank 101 is installed on the inner wall of the mounting bracket 100, and a stirring assembly 200 is installed inside the processing tank 101, wherein:

[0022] The stirring component 200 accelerates the mixing speed of chlorine and paraffin while ensuring thorough mixing of the two substances.

[0023] The improvement in this embodiment is as follows:

[0024] The stirring component 200 can rapidly stir chlorine and paraffin, ensuring thorough mixing and accelerating the chlorination reaction rate, thus improving production efficiency. Compared to traditional static mixing methods, this dynamic stirring method can distribute reactants more evenly, reducing localized over-reaction or incomplete reaction, thereby improving product quality.

[0025] First, to ensure thorough and uniform mixing of paraffin and chlorine, the stirring assembly 200 includes a support rod 201 and several frames 202. The outer wall of the support rod 201 has a ring array of guide rails 2010, with grooves on their side walls. Slider blocks 2022 are mounted on the side walls of the frames 202, slidingly engaging with the grooves. Several bolts 2023 are provided on the outer wall of the guide rails 2010, securing the guide rails 2010 and sliders 2022. Inside the frames 202, several horizontal plates 2020 and several vertical plates 2021 are installed, forming a plate structure with several rectangular holes. The outer wall of the frame 202 is flush with the inner wall of the processing tank 101.

[0026] The sliding engagement between slider 2022 and chute allows frame 202 to move smoothly up and down along guide rail 2010. The chute provides slider 2022 with a precise movement trajectory, reducing jamming and frictional resistance during movement, facilitating the assembly and disassembly of the mixing assembly 200. When maintenance or replacement of parts is required, frame 202 can be easily removed from guide rail 2010, improving maintainability. Bolt 2023 secures guide rail 2010 and slider 2022, ensuring a firm and reliable connection. During mixing, even under significant external impact or vibration, the connection between guide rail 2010 and slider 2022 remains secure, guaranteeing normal operation of mixing assembly 200. The design with several rectangular holes reduces weight while maintaining frame 202 strength, and the layout of horizontal plate 2020 and vertical plate 2021 allows for better flow and mixing of materials within frame 202. During the stirring process, paraffin and chlorine can flow freely between the horizontal plate 2020 and the vertical plate 2021, increasing the contact area of ​​the materials and the reaction efficiency, thus making the reaction more complete, the product quality higher, and improving the reaction efficiency. The design of the outer wall of the frame 202 fitting snugly against the inner wall of the processing tank 101 makes the position of the stirring component 200 more stable within the processing tank 101, avoiding damage to the processing tank 101 caused by the shaking of the stirring component 200. At the same time, stable stirring operation helps maintain the consistency of reaction conditions, improves the stability of product quality, and prevents the stickiness of paraffin from adhering to the inner wall of the processing tank 101, facilitating subsequent cleaning.

[0027] Secondly, a sealing cover 1010 is provided at the top of the processing tank 101, and a support base 1011 is installed at the center of the top of the sealing cover 1010. A drive motor 1012 is installed on the surface of the support base 1011, and the output end of the drive motor 1012 is connected to the top of the support rod 201. The sealing cover 1010 effectively prevents chlorine gas from leaking to the outside during the reaction process, ensuring the safety of the operators and reducing environmental pollution. The drive motor 1012 provides power to the stirring assembly 200, and drives the support rod 201 and the frame 202 to rotate through the rotational motion of the output end, thereby realizing the stirring and mixing of paraffin and chlorine gas.

[0028] In addition, a feed inlet 1013 is installed on the surface of the sealing cap 1010, and a discharge outlet 1014 is installed at the bottom of the processing tank 101. The feed inlet 1013 is used to add reaction raw materials such as paraffin into the processing tank 101. Its reasonable position design helps the raw materials to enter smoothly and be evenly distributed. The discharge outlet 1014 facilitates the discharge of the chlorinated paraffin product after reaction from the processing tank 101, which is convenient for subsequent separation, refining and packaging processes.

[0029] In practical use, the operator opens the inlet 1013 on the sealing cover 1010 and adds an appropriate amount of paraffin and other reactants into the processing tank 101 through the inlet 1013. The amount added is determined according to production requirements and reaction formula. After adding the reactants, the valve of the inlet 1013 is closed, and the sealing cover 1010 is tightly sealed to the processing tank 101. Then, chlorine gas is introduced into the processing tank 101, and the drive motor 1012 is started to make the stirring component 200 start stirring the paraffin and chlorine gas. Under the action of the stirring component 200, the chlorine gas and paraffin gradually mix thoroughly and react to produce chlorinated paraffin. When the reaction reaches the predetermined time or extent, the chlorine gas is stopped, and the drive motor 1012 is turned off, so that the stirring component 200 stops rotating. Then, the outlet 1014 valve at the bottom of the processing tank 101 is opened to discharge the generated chlorinated paraffin into the collection container.
