Description

Technical Field

[0001] This utility model belongs to the technical field of rosin processing equipment, specifically relating to a high-pressure stirring device for rosin hydrogenation. Background Technology

[0002] Rosin, as an important natural resin, has wide applications in many fields such as adhesives, coatings, inks, and electronics. However, ordinary rosin has disadvantages such as easy oxidation and poor thermal stability. Hydrogenation can effectively improve these properties, thereby enhancing the quality and application value of rosin. In the rosin hydrogenation process, the stirring device plays a crucial role.

[0003] Existing high-pressure stirring devices for rosin hydrogenation have many shortcomings:

[0004] Uneven mixing: Traditional stirring blades have a relatively simple design, which, under high pressure, cannot ensure that materials in all areas of the reactor can fully contact hydrogen and mix evenly. For example, rosin at the bottom of the reactor lacks fluidity, resulting in insufficient mixing with hydrogen and affecting hydrogenation efficiency.

[0005] Poor hydrogen dispersion: Hydrogen is a key reactant in the rosin hydrogenation reaction, but existing stirring devices cannot effectively disperse it within the material. Due to the significant density difference between hydrogen and liquid rosin, if not effectively dispersed, hydrogen tends to accumulate at the top of the reactor, failing to fully participate in the reaction and reducing hydrogen utilization. According to actual production data, the hydrogen utilization rate in traditional devices is only 60%-70%, which not only increases production costs but also prolongs reaction time and reduces production efficiency. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a high-pressure stirring device for rosin hydrogenation, which solves the problems of stirring effect and hydrogen dispersion in existing rosin hydrogenation devices. This high-pressure stirring device for rosin hydrogenation can effectively improve the rosin hydrogenation efficiency and hydrogen utilization rate.

[0007] This utility model provides a high-pressure stirring device for rosin hydrogenation, including a stirring tank, a top cover, a motor, a rotating shaft, spiral blades, a packing basket, a heating jacket, an annular pipe, a hydrogen supply device, a hydrogen recovery device, a hydrogen pipe, and a recovery pipe. The top cover is located on the top of the stirring tank, and the motor is located on the top of the top cover. The top cover is provided with a feed inlet and a pressure regulating valve. The packing basket, the annular pipe, and the rotating shaft are located inside the stirring tank. A catalyst fixed bed is provided in the packing basket. The top of the rotating shaft passes through the top cover and is connected to the motor. The bottom of the rotating shaft passes through the packing basket. The spiral blades are located at the bottom of the rotating shaft and below the packing basket. The heating jacket is located on the outer periphery of the stirring tank. The annular pipe is located below the packing basket and surrounds the spiral blades. The inner wall of the annular pipe has multiple vent holes. The hydrogen pipe is connected to the annular pipe and the hydrogen supply device, and the recovery pipe is connected to the pressure regulating valve and the hydrogen recovery device.

[0008] Furthermore, the heating jacket is provided with a heat transfer oil inlet and a heat transfer oil outlet.

[0009] Furthermore, the feed inlet is provided with a sealing cover.

[0010] Furthermore, the bottom of the mixing tank is provided with a discharge port, and the discharge port is provided with a discharge valve.

[0011] This rosin hydrogenation high-pressure stirring device features spiral blades at the bottom of the rotating shaft. The lifting effect generated by the rotation of the spiral blades effectively promotes the upward flow of rosin material at the bottom, ensuring full interaction between the rosin at the bottom and the catalyst bed at the top. Simultaneously, an annular tube is positioned at the bottom of the catalyst bed, allowing hydrogen to fully react with the rosin as it rises. This ensures a more uniform hydrogenation reaction, reducing batch-to-batch variations in product quality, improving the stability and consistency of the hydrogenated rosin product, and meeting the stringent quality requirements of high-end applications.
