[0002] Molecular sieve is a material containing precise and single tiny pores that can be used to adsorb gases or liquids. Unlike a normal sieve, it operates at the molecular level. Small enough molecules can be adsorbed through the pores, while larger molecules cannot. Molecular sieves are often used in the petroleum industry, especially for gas purification. During the production and processing of molecular sieves, the components of its raw material powder need to be mixed and stirred to fully mix the raw materials, thereby improving the quality of the produced molecular sieve.

[0003] Existing batching devices for molecular sieves, such as a molecular sieve raw material powder batching device disclosed in Chinese patent CN202320691047.1, adopt a single-stage stirring structure to achieve batching and mixing, but the mixing uniformity of the single-stage stirring structure is poor, and multiple stirrings are required to achieve uniform mixing. Based on this, the utility model proposes a molecular sieve raw material powder batching device, which adopts a two-stage mixer consisting of a premixing box and a swinging mixing mechanism, wherein the premixing box can premix the molecular sieve raw material by stirring, and the swinging mixing mechanism utilizes a back and forth swinging mixing bin to mix the raw materials. Since the mixing bin has a downward slope, the raw materials will slide into the mixing bin at the end after swinging and mixing, and be discharged from the discharging hopper. The mixing uniformity and efficiency of the device are high. Utility Model Content
