Description

Technical Field

[0001] The utility model relates to the technical field of catalyst feeding devices, in particular to a feeding buffer device for catalyst preparation. Background Art

[0002] During the production process, the pellet catalyst needs to be operated in a steam drying belt. After being treated in the steam drying belt, it needs to be unloaded. When unloading, since the pellet catalyst has a certain elasticity, the collision of unloading can easily cause the pellet material to jump out, which is not convenient for stable unloading.

[0003] According to the description in the special steam drying belt unloading device for pellet catalyst disclosed in the patent website (authorization announcement number: CN213415599U), "The utility model relates to the field of unloading technology, and discloses a special steam drying belt unloading device for pellet catalyst, including a conveyor belt and a bottom plate, a bracket is fixedly provided at the lower end of the conveyor belt, a plurality of baffle plates are evenly fixedly connected to the surface of the conveyor belt, a vertical pole is fixedly connected to the upper end of the bottom plate, a buffer bin is fixedly connected to the upper side rod wall of the vertical pole, a buffer cylinder of a conical structure is integrally connected to the lower end of the buffer bin, a discharge cylinder is integrally connected to the lower end of the buffer cylinder, a closing mouth is integrally connected to the upper end of the buffer bin, a U-shaped fixing plate is fixedly connected to the side wall of the conveyor belt, the U-shaped fixing plate is clamped outside the vertical pole, and the U-shaped fixing plate and the vertical pole are fixedly clamped by a clamping mechanism.

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the small ball catalyst falling into the buffer silo gradually falls through the buffer tube and the discharge tube of the conical structure, which greatly reduces the elastic potential energy it carries and makes the discharge stable. However, a large number of small balls are poured into the buffer barrel together, which will squeeze each other and cause blockage at the discharge tube mouth, thereby affecting the discharge effect. At the same time, the small ball catalyst is sent into the silo through the conveyor belt, but the silos are of different sizes and heights, and the fixed conveyor belt angle cannot be applied to different silos. Therefore, it is necessary to improve a catalyst preparation discharge buffer device to solve the above problems. Utility Model Content
