Description
Technical Field
[0001] This utility model relates to the field of pressure vessel technology, and in particular to a pressure vessel feeding device. Background Technology
[0002] A pressure vessel is a sealed, high-pressure reaction vessel that enhances the rate of chemical reactions and the solubility of materials by maintaining an environment higher than atmospheric pressure. It is widely used in hydrometallurgy, chemical synthesis, and materials preparation. Its core structure includes a high-pressure resistant shell, a stirring device, a heating / cooling system, and a safety valve.
[0003] In hydrometallurgical pressure leaching production, the horizontal pressure vessel is a key piece of equipment. The material is fed into the vessel through a hopper. To prevent hopper blockage, the traditional method is to install an agitator inside the hopper to maintain flow by moving the material. However, the existing agitator structure has limitations. It can only achieve local material disturbance and cannot drive the material in the hopper to form an overall convection circulation. This design defect causes the material to easily form local accumulation or bridging in the hopper, which significantly reduces the anti-blocking performance and affects the continuity of production.
[0004] Therefore, a new feeding device for a pressure vessel is proposed to address the above problems. Utility Model Content
