Description

Technical Field

[0001] This utility model relates to the field of phenolic resin reaction technology, and in particular to a phenolic resin reaction apparatus. Background Technology

[0002] Phenolic resin, as an important thermosetting polymer material, is widely used in coatings, adhesives, composite materials, and other fields. Its production process involves polycondensation reactions, requiring strict control of temperature, pressure, and material mixing uniformity. Traditional reaction equipment often uses batch reactors, with materials mixed by agitators. However, the viscosity of the system increases sharply in the later stages of the reaction, which can easily lead to local overheating and uneven reaction. With the increasing environmental protection requirements and the development of intelligent manufacturing, the industry has placed higher demands on the automation level, cleaning efficiency, and continuous production capacity of reaction equipment. Modern phenolic resin production equipment is developing towards integration and intelligence, with particular emphasis on solving key process challenges such as cleaning residues on the reactor inner wall and controlling material feeding. This is of great significance for improving product quality stability and reducing energy consumption.

[0003] Existing phenolic resin reaction equipment typically consists of a reaction vessel, a stirring system, a heating device, and a discharge mechanism. The stirring system usually uses anchor or paddle agitators, which are driven by a motor to achieve material mixing. The inner wall of the reaction vessel is usually made of stainless steel and is cleaned by high-pressure washing.

[0004] The main problem with existing technologies is that the inner wall of the reaction vessel is prone to material accumulation and difficult to clean. Because the viscosity of phenolic resin increases significantly in the later stages of the reaction, residual material adheres to the inner wall of the vessel, forming a stubborn deposit layer. Traditional rigid scrapers cannot completely remove these residues, leading to the introduction of degradation products into subsequent reactions, affecting product quality consistency. More seriously, the accumulated material gradually carbonizes, not only increasing cleaning difficulty but also becoming a reaction hotspot, causing localized overheating and even safety accidents. Therefore, a phenolic resin reaction apparatus is proposed to solve these problems. Utility Model Content

[0024] 1. In this utility model, the transmission roller is driven to rotate by the output end of the motor, which in turn drives the rotating plate to rotate. Simultaneously, the scraper inside the rotating plate rotates. At the same time, the scraper is squeezed by the inner wall of the reaction tank, causing the spring to be compressed. This achieves the effect of elastically scraping and cleaning the inner wall of the reaction tank, solving the problems of residual accumulation affecting subsequent reactions, difficulty in equipment cleaning, and cumbersome cleaning of tank wall material accumulation. It also improves the continuity of device operation and the convenience of maintenance.

[0025] 2. In this utility model, the output end of the electric telescopic rod drives the fixed column and connecting rod to rotate along the support column inside the support frame, which simultaneously drives the locking action of the connecting column and the sealing cover. Subsequently, the material is discharged through the guide frame and the discharge frame, thereby achieving the effect of automated material discharge and precise opening and closing. This solves the problems of frequent manual intervention, material leakage, and difficulty in controlling material discharge, as well as easy residue dripping, and improves the automation of the device.

The component operating parameters are as follows: The bottom of the reaction tank 2 is fixedly connected to the discharge pipe 6, which is used to discharge the material after the reaction is completed, ensuring a continuous production process. The top of the reaction tank 2 is fixedly connected to the motor 4, which provides power to drive the transmission roller 7 to rotate, realizing the stirring and cleaning functions. The output end of the motor 4 is fixedly connected to the transmission roller 7, which transmits the power of the motor 4 to the rotating plate 8, driving it to rotate. The outer wall of the transmission roller 7 is fixedly connected to the rotating plate 8, which rotates with the transmission roller 7, driving the scraper 9 to clean the inner wall of the reaction tank 2. The rotating plate 8 is equipped with a cleaning component.

[0035] The cleaning components include a scraper 9, which is used to scrape off residual materials adhering to the inner wall of the reaction vessel 2 to prevent material accumulation from affecting the reaction effect. The scraper 9 is slidably connected inside the transmission roller 7, so that the scraper 9 can adaptively adjust its position according to the shape of the inner wall of the reaction vessel 2. A spring 10 is set inside the rotating plate 8. The spring 10 provides elastic pressure to keep the scraper 9 in close contact with the inner wall of the reaction vessel 2, thereby improving the cleaning effect. One end of the spring 10 is fixedly connected inside the transmission roller 7, and the other end of the spring 10 is fixedly connected to the side wall of the scraper 9 to ensure that the scraper 9 can compress the spring 10 and maintain stable contact when under force. A guide frame 11 is fixedly connected to one end of the discharge pipe 6. The guide frame 11 is used to guide the flow of materials and prevent dripping and residue. A discharge component is set inside the guide frame 11 to control the discharge of materials and realize automated discharge.

[0036] Reference Figures 1-5The feeding assembly includes a feeding frame 12 and a sealing cover 17. The feeding frame 12 guides the discharge path of the reacted materials, ensuring smooth and residue-free feeding. The side wall of the feeding frame 12 is fixedly connected to the side wall of the guide frame 11, forming a stable feeding channel structure. The sealing cover 17 fits snugly against the guide frame 11 to seal the feeding port and prevent material leakage, while ensuring the accuracy of opening and closing actions. A transmission roller 7 is fixedly connected inside the support frame 1, providing structural support and maintaining the stability of the transmission system. The bottoms of both the guide frame 11 and the feeding frame 12 are fixedly connected inside the transmission roller 7, ensuring the linkage and coordination between the feeding mechanism and the reaction tank 2. An electric telescopic rod 13 is provided at the top of the guide frame 11 as a power source to control the opening and closing action of the sealing cover 17. The bottom of the electric telescopic rod 13 is rotatably connected to the top of the guide frame 11, allowing the electric telescopic rod 13 to adjust its angle within a certain range to adapt to the opening and closing stroke. A fixed column 14 is fixedly connected to the output end. The fixed column 14 serves as the fulcrum of the connecting rod 15 to transmit the thrust of the electric telescopic rod 13. The outer wall of the fixed column 14 is rotatably connected to the connecting rod 15, which converts linear motion into rotational motion to drive the sealing cover 17. A connecting column 16 is fixedly connected to the bottom of the connecting rod 15. The connecting column 16 serves as a force transmission component to transmit motion to the sealing cover 17. One end of the connecting column 16 is fixedly connected to the outer wall of the sealing cover 17, directly controlling the opening and closing state of the sealing cover 17. A support column 18 is fixedly connected to the outer wall of the connecting rod 15. The support column 18 provides additional support points to enhance the stability of the connecting rod 15.

One side of the support frame 19 is fixedly connected inside the guide frame 11.

[0037] Working principle: When the device is running, the output end of motor 4 drives the transmission roller 7 to rotate. The rotation of transmission roller 7 in turn drives the rotating plate 8 fixedly connected to the outer wall to rotate synchronously. The rotation of rotating plate 8 stirs and mixes the material in reaction tank 2. At the same time, the rotation of transmission roller 7 drives the scraper 9 slidably connected inside it to rotate as well. During the rotation of scraper 9, it contacts and squeezes against the inner wall of reaction tank 2, causing the spring 10 set inside rotating plate 8 to be compressed. The elasticity of spring 10 keeps scraper 9 in contact with the inner wall of reaction tank 2, realizing elastic adaptive scraping and cleaning of the inner wall of reaction tank 2. When discharging, the guide frame 11 tops... The electric telescopic rod 13 installed in the part operates, and the output end of the electric telescopic rod 13 drives the fixed column 14 to move. The movement of the fixed column 14 drives the connecting rod 15, which is rotatably connected to the outer wall, to move. The movement of the connecting rod 15 drives the connecting column 16, which is fixedly connected to the bottom, to move. The movement of the connecting column 16 then drives the sealing cover 17, which is fixedly connected to one end, to move relative to the guide frame 11, thereby achieving a locking action. At the same time, the support column 18, which is fixedly connected to the outer wall of the connecting rod 15, rotates inside the support frame 19 to assist the connecting rod 15 in stabilizing its movement. Finally, the material enters the guide frame 11 through the discharge pipe 6 and is discharged through the discharge frame 12.
