Description

Technical Field

[0001] This utility model relates to the field of chemical raw material condensation technology, specifically to a condensation and reflux mechanism for organic chemical raw materials. Background Technology

[0002] Currently, existing condensation reflux mechanisms have certain limitations. For example, a condensation reflux mechanism disclosed in publication number CN212974235U includes a first reactor, a second reactor, and a first container disposed between the first and second reactors. The first reactor has a first vent pipe connected to one side of its upper part and a first reflux pipe connected to the other side. The second reactor has a second vent pipe connected to one side of its upper part and a second reflux pipe connected to the other side. A condenser is connected inside the first container. When either the first or second reactor is continuously operating, the gaseous material from the first or second vent pipe escapes into the first container and accumulates there. The gaseous material accumulated in the first container exchanges heat with the coolant in the condenser until it transforms into a liquid. The liquid then flows back into the first or second reactor to continue participating in the reaction. Although this technical solution improves the efficiency of the condensation reflux mechanism to some extent, some problems still need to be solved in practical applications.

[0003] During the condensation process, chemical raw materials condense and form condensate on the inner wall of the condenser tube. As the reaction continues, the condensate accumulates. However, existing condensation reflux mechanisms are not ideal for scraping off the condensate from the condenser tube. This results in the condensate adhering to the tube wall for an excessively long time, which not only affects the condensation effect and reduces condensation efficiency, but also makes it difficult to completely remove the condensate during subsequent cleaning. The residual condensate may affect the quality and efficiency of the next reaction, and may even cause corrosion and other damage to the equipment, increasing maintenance costs and operational risks. Utility Model Content

[0004] The purpose of this invention is to provide an organic chemical raw material condensation and reflux mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an organic chemical raw material condensation and reflux mechanism, comprising a cooling pipe connected to an organic chemical raw material reaction vessel, wherein a scraping component for scraping off the chemical raw material condensate on the inner wall of the cooling pipe is installed inside the cooling pipe, and a driving component for driving the scraping component to reciprocate is installed on the side of the cooling pipe corresponding to the position of the scraping component.

[0006] Optionally, the scraping assembly includes a movable ring, which is movably disposed inside the cooling pipe, and the edge of the movable ring is provided with a scraping ring that matches the inner wall of the cooling pipe.

[0007] Optionally, a connecting rod is fixedly connected to the inner wall of the moving ring, and a threaded cylinder for driving the connecting rod to move is installed on the side of the connecting rod, and the threaded cylinder is slidably connected to the side of the cooling pipe.

[0008] Optionally, the drive assembly package is fixedly connected to the mounting bracket on the side of the cooling pipe. A forward and reverse motor is mounted on the side of the mounting bracket. A threaded shaft is fixedly connected to the output shaft of the forward and reverse motor, and the threaded shaft is threadedly connected to the inner wall of the threaded cylinder.

[0009] Optionally, a sealing ring is installed on the side of the cooling pipe at a position corresponding to the threaded cylinder.

[0010] Optionally, a limiting slider is fixedly connected to both the top and bottom of one side of the threaded cylinder, and a limiting groove matching the limiting slider is provided on the mounting bracket at the position corresponding to the limiting slider.

[0011] Optionally, the side of the cooling pipe is connected to the organic chemical raw material reactor via an air inlet pipe, and a collection pipe for collecting chemical raw material condensate is installed on one side of the bottom of the cooling pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The organic chemical raw material condensation and reflux mechanism provided by this utility model can conveniently, efficiently and thoroughly scrape the condensate off the tube wall by installing a scraping component inside the cooling tube and a drive component on the side. It can also reciprocate to ensure continuous and efficient operation. The installed sealing ring can prevent raw material leakage, and the limiting slider and slide groove ensure that the component operates smoothly and accurately. Timely scraping of condensate can provide a stable environment for the reaction and avoid adverse effects on subsequent reactions.

[0013] 2. In this invention, by installing a scraping component inside the cooling pipe and setting a driving component on the side of the cooling pipe, convenient and efficient scraping of chemical raw material condensate on the inner wall of the cooling pipe is achieved. When the chemical raw material condenses on the pipe wall inside the cooling pipe, the forward and reverse motor in the driving component drives the threaded shaft to rotate. Under the action of the threaded cylinder and the threaded shaft, the moving ring at the end of the threaded cylinder moves to the right. The scraping ring at the edge of the moving ring can tightly fit against the inner wall of the cooling pipe, thoroughly scraping away the condensate, which is then discharged along the collection pipe. This method greatly improves the convenience and thoroughness of condensate discharge and avoids long-term residue of condensate on the pipe wall.

[0014] 3. In this invention, after scraping is completed, the moving ring can be moved to the initial position on the left by rotating the forward and reverse motor in the opposite direction, so as to facilitate the scraping of condensate next time. This reciprocating operation design enables the condensation reflux mechanism to operate continuously and stably, and to clean up the condensate in a timely manner after each reaction, ensuring the continuity and efficiency of the condensation process and effectively improving the production efficiency of the entire organic chemical raw material reaction.

[0015] 4. In this invention, a sealing ring is installed on the side of the cooling pipe, corresponding to the position of the threaded cylinder, which effectively prevents leakage of chemical raw materials inside the cooling pipe, ensuring the safety and stability of equipment operation. Simultaneously, the limiting slider on one side of the threaded cylinder matches the limiting groove on the mounting frame, providing precise guidance and limiting for the reciprocating movement of the moving ring, ensuring the smoothness and accuracy of the scraping component's operation, and further improving the reliability and service life of the equipment.

[0018] 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.

[0019] Please see Figure 1-4 An organic chemical raw material condensation and reflux mechanism includes a cooling pipe 1 connected to an organic chemical raw material reaction vessel. The cooling pipe 1 serves as a core component, providing a place for the condensation of chemical raw materials. A scraping component 2 is installed inside the cooling pipe 1 to scrape off the condensate of chemical raw materials on the inner wall of the cooling pipe 1. A driving component 3 is installed on the side of the cooling pipe 1 at a position corresponding to the scraping component 2 to drive the scraping component 2 to reciprocate.

[0020] To precisely scrape away the condensate from the inner wall of the cooling pipe 1, the scraping assembly 2 includes a movable ring 201 movably disposed inside the cooling pipe 1. A scraper ring 2011, which fits tightly against the inner wall of the cooling pipe 1, is located at the edge of the movable ring 201. The scraper ring 2011 is made of a special material with excellent wear resistance and sealing properties. It can effectively scrape away the condensate from the pipe wall during movement without damaging the pipe wall. The design of the scraper ring 2011 ensures thorough scraping, minimizes condensate residue on the pipe wall, improves condensate recovery rate, and maintains the cleanliness of the inside of the cooling pipe 1, which is beneficial for the stable progress of subsequent reactions.

[0021] To drive the moving ring 201 to move within the cooling pipe 1, a connecting rod 202 is fixedly connected to the inner wall of the moving ring 201. A threaded cylinder 2021 for driving the moving connecting rod 202 is mounted on the side of the connecting rod 202, and the threaded cylinder 2021 is slidably connected to the side of the cooling pipe 1. The drive assembly 3 includes a mounting bracket 301 fixedly connected to the side of the cooling pipe 1. A forward and reverse motor 3011 is mounted on the side of the mounting bracket 301. A threaded shaft 3012 is fixedly connected to the output shaft of the forward and reverse motor 3011, and the threaded shaft 3012 is threadedly connected to the inner wall of the threaded cylinder 2021. When the forward and reverse motor 3011 starts, it drives the threaded shaft 3012 to rotate, causing the threaded cylinder 2021 to move through the threaded transmission, thereby driving the connecting rod 202 and the moving ring 201 to move. This drive method has a simple structure, stable operation, and can accurately control the moving distance and speed of the moving ring 201, realizing the automation and precision of the scraping operation, improving work efficiency, and reducing errors and labor intensity of manual operation.

[0022] To prevent leakage of chemical raw materials inside the cooling pipe 1, a sealing ring 203 is installed on the side of the cooling pipe 1, corresponding to the position of the threaded cylinder 2021. The sealing ring 203 is made of high-performance sealing material, with good elasticity and sealing performance. It can effectively fill the gap between the threaded cylinder 2021 and the cooling pipe 1, preventing leakage of chemical raw materials. The installation of the sealing ring 203 ensures the safety of equipment operation, avoids environmental pollution and equipment corrosion caused by chemical raw material leakage, reduces maintenance costs, and ensures the stability and reliability of the condensation reflux process.

[0023] To ensure the stability of the movement of the threaded cylinder 2021, limit sliders 204 are fixedly connected to the top and bottom of one side of the threaded cylinder 2021. A limit groove 2041, matching the limit slider 204, is provided on the mounting bracket 301 at the corresponding position. The limit slider 204 slides within the limit groove 2041, restricting the rotation of the threaded cylinder 2021 and ensuring it can only move in a straight line. The existence of this limiting structure guarantees the smoothness and accuracy of the scraping assembly 2's operation, avoiding uneven scraping or jamming caused by the rotation of the threaded cylinder 2021, improving the quality and efficiency of the scraping work, and extending the service life of the equipment.

[0024] To facilitate the flow of chemical raw materials and the collection of condensate, the side of cooling pipe 1 is connected to the organic chemical raw material reactor via an air inlet pipe 101. A collection pipe 1011 for collecting chemical raw material condensate is installed on one side of the bottom of cooling pipe 1. The air inlet pipe 101 introduces the gaseous chemical raw materials generated in the reactor into cooling pipe 1 for condensation, while the collection pipe 1011 collects and discharges the scraped condensate. This connection and collection method forms a complete closed loop in the entire condensation and reflux process, achieving effective recycling of chemical raw materials and improving raw material utilization. Simultaneously, the design of the collection pipe 1011 facilitates the collection and treatment of condensate, enabling subsequent analysis and reuse.

[0025] When using: Cooling pipe 1 condenses the chemical raw materials flowing from the reactor, causing condensate to form on the pipe wall. The reversible motor 3011 starts, driving the threaded shaft 3012 to rotate. Under the action of the threads of the threaded cylinder 2021 and the threaded shaft 3012, the threaded cylinder 2021 slides along the side of cooling pipe 1, causing the moving ring 201 at its end to move to the right. The scraping ring 2011 then scrapes off the condensate from the inner wall of cooling pipe 1. The scraped condensate flows down the inner wall of cooling pipe 1 to the collection pipe 1011 at the bottom and is discharged. After scraping is complete, the reversible motor 3011 rotates in the opposite direction, moving the moving ring 201 to the initial position on the left for the next condensate scraping. This repeated operation allows for convenient and thorough scraping of the condensate from the inner wall of cooling pipe 1.
