Description
Technical Field
[0001] This utility model relates to the field of stirring technology for modified phenolic resins, and more particularly to a stirring device for modified phenolic resins. Background Technology
[0002] In the field of chemical materials, modified phenolic resins are widely used in the production of molding compounds, coatings, adhesives, and composite materials due to their excellent heat resistance, insulation, and adhesive properties. To obtain specific physicochemical properties, phenolic resins typically require modification treatment, such as blending with other polymers or introducing specific functional groups. During the modification process, uniform mixing of materials is a crucial step determining the quality of the final product. Therefore, the stirring mechanism, as the core equipment for achieving sufficient material dispersion, heat transfer, and reaction, directly affects the performance uniformity and production stability of the modified phenolic resin through its structural design and operational efficiency.
[0003] Currently, most widely used modified phenolic resin stirring devices on the market adopt a single rotary stirring blade structure. The working principle of this type of device is that the stirring blade is directly driven by a motor, so that it moves at a constant speed in a high-speed circular motion within a sealed reaction tank. When the blade rotates, the friction between the blade surface and the raw material, as well as the power generated by the stirring of the blade, promotes the mixing of the raw material within the reaction tank. This stirring method has a simple structure and low cost. In the early production of modified phenolic resin, it could meet the needs of small-scale production with low requirements for product quality and is suitable for some general industrial product production scenarios where the requirements for mixing uniformity are relatively relaxed. However, during the stirring process, the force generated by the single rotary stirring blade is mainly concentrated in the horizontal direction, and the stirring force in the vertical direction is weak. It is difficult to effectively drive the bottom raw material to participate in the overall mixing cycle. After a long period of stirring, the raw material at the bottom of the reaction tank is still in a localized aggregated state and cannot be fully integrated with the upper raw material, resulting in uneven mixing. This affects the quality stability of the modified phenolic resin and reduces production efficiency. Therefore, a stirring device for modified phenolic resin is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a stirring device for modified phenolic resin, which aims to improve the problem of uneven mixing of raw materials during the stirring process.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stirring device for modified phenolic resin includes a reaction vessel, a top cover on the top of the reaction vessel, a motor on the top of the top cover, a stirring mechanism fixedly connected to the output end of the motor, and a transport mechanism at the bottom of the reaction vessel. The stirring mechanism includes a transmission block, the top of which is fixedly connected to an output end of a motor. A rotating platform is fixedly connected to the bottom of the transmission block, and a sleeve is fixedly connected to the bottom of the rotating platform. A sliding groove is provided inside the sleeve, and a sliding block is slidably connected inside the sleeve. A connecting block is fixedly connected to the side wall of the sliding block and slidably connected inside the sliding groove. A stirring rod is fixedly connected to the bottom of the sliding block, and a fan blade is fixedly connected to the outer wall of the stirring rod.
[0006] As a further description of the above technical solution: The transport mechanism includes a discharge pipe, which is fixedly connected inside the reaction tank. A valve is installed outside the discharge pipe and is fixedly connected to the bottom of the reaction tank. A feeding pipe is fixedly connected to the bottom of the discharge pipe. A rotating shaft is installed inside the feeding pipe. A second output end of a motor is fixedly connected to the side wall of the feeding pipe. A rotating shaft is fixedly connected to the second output end of the motor. An auger plate is fixedly connected to the side wall of the rotating shaft.
[0007] As a further description of the above technical solution: The bottom of the reaction vessel is equipped with a support, and the rotating platform is rotatably connected to the inner wall of the reaction vessel.
[0008] As a further description of the above technical solution: The outer wall of the auger blade is in contact with the inner wall of the feed pipe. As a further description of the above technical solution: The top cover is provided with a protective cover, which is located outside the motor.
[0009] As a further description of the above technical solution: A protective cover is fixedly connected to the side wall of the feeding pipe, and the protective cover is fitted over the outside of the motor.
[0010] As a further description of the above technical solution: A connecting rod 1 is fixedly connected to the side wall of the feeding pipe, and the top end of the connecting rod 1 is fixedly connected to the bottom of the reaction tank. A connecting rod 2 is fixedly connected to the side wall of the protective cover, and the top end of the connecting rod 2 is fixedly connected to the bottom of the reaction tank.
[0011] This utility model has the following beneficial effects: 1. In this utility model, by starting the motor, the transmission block rotates and drives the connecting block on the outer wall of the sliding block to slide in the groove inside the sleeve, converting the spiral motion of the sliding block into the vertical motion of the stirring rod. This allows the fan blade to move vertically in the reaction tank while stirring the raw materials, thereby achieving the effect of uniformly mixing the raw materials in the reaction tank. This solves the problem of uneven mixing after the raw materials settle to the bottom during the stirring process, and improves the adaptability and efficiency of the equipment.
[0012] 2. In this utility model, by opening the top cover, the required raw materials for stirring are placed into the reaction tank. After stirring, the valve is opened and the product passes through the discharge pipe. At this time, the motor is started, and the rotating shaft drives the auger blades to feed the product, thus achieving the effect of sealed transportation of raw materials. This solves the problem of toxic substances being generated by the volatilization of raw materials during transportation and improves the safety of the equipment. Attached Figure Description

The valve 13 is fixedly connected to the bottom of the reaction tank 1.

To facilitate the propulsion of raw materials, a support 22 is installed at the bottom of the reaction tank 1 to support the reaction tank 1 and provide a stable foundation, thus preventing vibration and displacement.

After feeding is completed, close the top cover 2 and the raw material feeding stops. After the raw materials enter the reaction tank 1, the motor 4 is started to drive the transmission block 5, so that the rotary table 6 starts to rotate. At the same time, the connecting block 10 on the sliding block 9 slides in the groove 8 opened in the sleeve 7, so that the sliding block 9 drives the stirring rod 11 to move vertically up and down, while the fan blade 12 rotates to stir and mix the raw materials. After the reaction is complete, motor 4 is turned off and the stirring mechanism stops running.
