Description

Technical Field

[0001] The invention relates to the technical field of molecular sieve production equipment, and in particular to a molecular sieve raw material crushing and conveying device. Background Art

[0002] Molecular sieve is a material such as crystalline aluminosilicate or natural zeolite with uniform microporous structure. Molecular sieve has a regular pore structure with uniform pore size. These pores can selectively adsorb, separate and catalyze molecules according to their size and shape. Different types of molecular sieves have different pore sizes and chemical properties to meet different application requirements. In molecular sieve production, raw material agglomeration is a common problem, which will have many adverse effects on the production process and product quality.

[0003] Existing equipment often cannot achieve high uniformity of molecular sieve raw material particle size through one-time crushing. It is impossible to cut the raw material into relatively uniform size before fine crushing, resulting in uneven particle size of the molecular sieve raw material after crushing, which will affect the performance stability and consistency of the molecular sieve in subsequent use. At the same time, the existing equipment cannot evenly deliver the molecular sieve raw material to the crushing component. The feed is unstable, sometimes too much and sometimes too little, affecting the crushing efficiency and quality.

[0004] The existing technology only uses a blower to transport the crushed molecular sieve raw materials, which has a slow conveying speed and is prone to clogging, reducing production efficiency. At the same time, the existing equipment cannot dry the molecular sieve raw materials. If drying is required, additional equipment is required. If the molecular sieve raw materials contain too much water, it will affect the crushing particle size. Existing equipment often cannot effectively avoid dust during feeding. Dust escaping from the feed port not only pollutes the working environment and harms the health of operators, but may also cause safety hazards such as dust explosions.

[0005] Based on this, the present invention designs a molecular sieve raw material crushing and conveying device to solve the above problems. Summary of the invention
