Description

Technical Field

[0001] The utility model relates to the technical field of screening and dust removal devices for molecular sieve production, in particular to a screening and dust removal device for molecular sieve production. Background Art

[0002] Molecular sieve is a synthetic hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules. The molecular sieve has many channels with uniform pore sizes and neatly arranged holes in its structure. Molecular sieves of different pore sizes separate molecules of different sizes and shapes. It has high adsorption capacity, strong selectivity, and high temperature resistance. It is widely used in organic chemical and petrochemical industries. It is also an excellent adsorbent for gas dehydration. It is also increasingly valued in waste gas purification. The production process of molecular sieve includes raw material mixing, granulation, screening, drying, roasting and packaging. The producer screens out the molecular sieve semi-finished particles with particle sizes that meet the production requirements through the screening process, thereby ensuring the particle size consistency of the molecular sieve finished product after production. Among them, powdery debris is easily generated during the granulation and crushing of the molecular sieve. Due to the low adsorption capacity of the debris, if it is not removed, the quality of the carbon molecular sieve is reduced, and dust is generated during the screening process, so it needs to be treated.

[0003] The Chinese patent with the publication number CN115999890A discloses a screening dust removal device for molecular sieve production, including a container; a support is fixed to the inner wall of the container, a vibrating screen is connected to the support, and the vibrating screen corresponds to the lower part of the feed port; an elastic mechanism is arranged between the support and the vibrating screen; a wind-blown dust channel is arranged below the vibrating screen to blow away the dust falling on the vibrating screen. Applying the technical scheme of the present invention, the molecular sieve enters the container from the feed port and is loaded on the vibrating screen; the vibrating screen vibrates, and the molecular sieve falls down evenly from the sieve holes of the vibrating screen. When the molecular sieve falls through the wind-blown dust channel, the dust on the surface of the molecular sieve is blown away by the wind; in addition, when the molecular sieve falls, the powdery debris mixed in the molecular sieve can fall from the sieve holes, and the wind blows it away together. In the screening dust removal device for molecular sieve production, the molecular sieve enters the container from the feed port and is blown away by the wind, and the dust removal is timely and effective.

[0004] However, the above patent has the following shortcomings: in the process of blowing the material, although the powdery debris mixed in the molecular sieve can be blown away by blowing during the falling process, the powdery debris mixed in the molecular sieve has a relatively limited falling time, so some powdery debris will not be blown away by the wind.
