Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieve processing, and particularly relates to a device for preparing molecular sieves. Background Art

[0002] Molecular sieve is a kind of silicon-aluminate compound with a cubic lattice and has a uniform microporous structure. The pore diameters of its cavities are of uniform size. These cavities can adsorb molecules smaller than their diameters into the interior of the cavities, and have a preferential adsorption capacity for polar molecules and unsaturated molecules. Therefore, molecules with different degrees of polarity, different degrees of saturation, different molecular sizes and different boiling points can be separated, that is, it has the function of "screening" molecules, so it is called molecular sieve. Because molecular sieve has advantages such as high adsorption capacity and strong thermal stability that other adsorbents do not have, molecular sieve has been widely used.

[0003] The "raw material mixing device for preparing carbon molecular sieve" disclosed in the patent application with the application number of "202221913077.4" "comprises a box body, the lower surface of the box body is fixedly connected with box legs, a support plate is fixedly connected between the box legs, a motor is fixedly installed on the upper surface of the support plate, the output end of the motor penetrates through the box body and is movably connected with the box body through a first bearing, and the output end of the motor is fixedly connected with a rotating cylinder. The top end of the rotating cylinder is movably connected with the inner top wall of the box body through a second bearing. Wave grooves are formed on the surface of the rotating cylinder, one end of a connecting rod is slidably connected in the wave grooves, sliding rods are fixedly connected to the left and right inner walls of the box body respectively, the other end of the connecting rod is slidably connected with the corresponding sliding rod, and a lifting plate is fixedly connected to the lower side of the connecting rod". In the utility model, through the cooperation of the rotating cylinder, the stirring rod, the fixed column, the wave grooves and the lifting plate, while the motor rotates to drive the rotating cylinder to rotate for stirring, the rotating cylinder can drive the connecting rod and the lifting plate to rise and fall through the wave grooves, so that the raw materials below and above are alternately mixed, and the purpose of full stirring can be achieved in cooperation with the stirring rod. Moreover, when the rotating cylinder rotates, the stirring rod rotates itself through the cooperation of the second gear and the first gear, enhancing the mixing effect.

[0004] However, the above method still has the following defects: both the second gear and the first gear are located inside the box body. During the stirring process, the first gear and the second gear will be immersed in the raw materials, resulting in gear jamming, which will affect the progress of the stirring activity and has poor reliability. In addition, the stirring rod is only supported at one end by the rotating cylinder and does not have two-end support, so the stability is relatively poor. Summary of the Utility Model
