Storage tank type classified sorting system with dust removal function

Abstract

The invention discloses a storage tank type classified sorting system with a dust removal function. The system comprises a storage tank type classified sorting device and a warm induced air device. The storage tank type classified sorting device comprises a tank body, an inverted-funnel-shaped cyclone portion and four partition plates. The inverted-funnel-shaped cyclone portion is arranged on the upper portion of the tank body. The outer side wall of the inverted-funnel-shaped cyclone portion and upper space of the tank body form an airtight heat exchange cooling chamber. The heat exchange cooling chamber is provided with a cold air inlet and a hot air outlet. The inner side wall of the inverted-funnel-shaped cyclone portion and the middle space of the tank body form a cyclone classified sorting chamber. The cyclone classified sorting chamber is provided with an air inlet and an air outlet. The partition plates are arranged on the lower portion of the tank body to divide a bottom cavity of the tank body into four fan-shaped cavities. The arm induced air device is used for forming continuous circulation airflow having a negative pressure sucking effect. The design is scientific and reasonable, classified screening and dust removal are carried out during material storage, the production procedures are simplified, and the production efficiency and quality of expanded perlite are improved.

Description

technical field [0001] The invention relates to perlite processing equipment, in particular to a storage tank type grading material selection system with dust removal function for grading expanded perlite finished products. Background technique [0002] Perlite is widely used in various fields, and the dominant use of perlite mines at home and abroad is to produce expanded perlite and its products. At present, the annual output of expanded perlite in my country has exceeded 4 million m 3 . my country has developed and utilized perlite mineral resources since the 1960s, but the processing and utilization of perlite resources in my country is still in the extensive processing stage, and the processing equipment is relatively backward. The general sand making process is: ore feeding-jaw crushing- Rotary kiln drying—fine hammer crushing—vertical impact crushing (roller crusher)—screening and grading. The outstanding problem in this process is that the existing sand making proce...

my country has developed and utilized perlite mineral resources since the 1960s, but the processing and utilization of perlite resources in my country is still in the extensive processing stage, and the processing equipment is relatively backward. The general sand making process is: ore feeding-jaw crushing- Rotary kiln drying—fine hammer crushing—vertical impact crushing (roller crusher)—screening and grading. The outstanding problem in this process is that the existing sand making process mostly uses multi-layer linear vibrating screens for screening and grading. Not only the equipment Complex structure and cumbersome screening process

In addition, the existing expanded perlite finished product storage equipment is relatively simple, especially the tank storage in use, which does not have the functions of classifying and sorting the expanded perlite finished product material and removing dust. First, it causes perlite particles with different particle sizes Second, even if external screening equipment is used for grading and screening, the screened residues will be discarded directly or put into the next batch of raw materials, which will either cause serious waste or affect the next batch of perlite. The sand production process increases the burden, because the residual material does not need to be reprocessed, only some of the steps are needed, and the whole process is too expensive for production and processing.
