Abstract
The present invention is characterized by changing original dry method to produce pearlite ore sand into water-injection method to grade and screen pearlite ore sand, that is, adding a set of water injection equipment on the original equipment, including water tank, water-injecting pipe connecting to hopper charging bucket and water-spraying pipe connecting onto sieve. Said invention raises the purity of pearlite ore sand, prolongs the production period, and its recovering rate of the product can be up to 85%.
Description
The present invention relates to a kind of improved sizing screening pearlite ore sand by water injection method.The ore of electing can directly drop into this machined, is not subjected to the restriction in rainy day and season, does not need airing or oven dry, and product recovery rate can reach 85%, ground degree height, the letter number height that expands, no dust.
The processing perlite ore all adopts airing or oven drying method both at home and abroad at present, wastes energy, and it is with short production cycle influenced by the rainy day, and product recovery rate is low, the waste resource.Dust is big, contaminated environment.
The present invention seeks to: the gram branch utilizes ore resource to improve product recovery rate and product quality, and the increase output that extends manufacture cycle is eliminated dust pollution.Improve working conditions.Improve the expansion letter number of perlite ore.
The present invention is achieved in that water is injected in the pulverizer simultaneously with ore, is difficult for adhering to the pulverizer inwall or is clumped together by pulverized perlite ore of water flushing action and dust and block pulverizer; Through pulverizing and the ore in sand form of washing is scattered in pulverizer and also continues to add water when sieve is gone up, wash ore in sand form on the one hand and obtain the higher perlite ore of purity; Form a sieve during on the other hand with sieving-free not to the utmost.The ore in sand form of falling on the sieve (2) through (1) sieve that sieves is a 20-40 order perlite ore; (2) sieve the 40-60 order perlite ore of falling on the sieve (3) through sieving; What fall is tailings and mortar through (3) sieve that sieves.
Simple structure of the present invention and work flow will describe in further detail the present invention in conjunction with the following drawings:
Fig. 1 is a kind of structure of the present invention and work flow schematic diagram.
With reference to Fig. 1, one connects water pipe (5) feeding pulverizer (6) water pipe (7) by water tank (8) and has the top that several spray orifices (9) are suspended in sieve (1).Below the sieve (1) is corresponding sieve (2); Below the sieve (2) is corresponding sieve (3).
Work flow is, ore is dropped into hopper (4) while water pipe (5) toward hopper (4) lining water filling, be scattering on the sieve (1) through the chippy ore in sand form band of pulverizer (6) water, continue toward the ore in sand form water spray that sieves on (1) by several spray orifices (9) on the water pipe (7) simultaneously, the flushing ore in sand form, through sizing screening, two material on the sieve (1) return pulverizer (6) sieve (1) sieve and drop on down that ore in sand form is the pure perlite ore of 20-40 purpose on the sieve (2); The ore in sand form that sieve (2) sieve drops on the sieve (3) down is the pure perlite ore of 40-60 purpose; Under sieve (3) sieve is tailings and mortar.
The feature of sizing screening pearlite ore sand by water injection method is: perlite ore purity height, strengthened the requirement of water to the expansion condition of perlite ore, and not limited by rainy season, extend manufacture cycle and improved product recovery rate and can reach 85%; Can make full use of ore resource and energy savings can increase exponentially economic benefit without airing oven dry ore.Product quality ranks " whole nation first ".Win " excellent product " title.
This shows that this produces perlite ore for raising and has opened up new way.Change former dry working system into the water filling working system and just can significantly improve economic benefit, this promotes national economic development to development perlite ore industry can play positive role.
Claims (3)
1 produces perlite ore with former seasoning changes sizing screening pearlite ore sand by water injection method into, it is characterized in that: increased water injection equipment water tank (8) on the equipment of original production perlite ore, water pipe (5) and water pipe (7) and several spray orifices (9).
The 2 sizing screening pearlite ore sand by water injection method devices by claim 1 regulation is characterized in that, water pipe (5) feed hopper (4) when feeding intake toward hopper (4) lining water filling.
The 3 sizing screening pearlite ore sand by water injection method devices by claim 1 regulation is characterized in that: water pipe (7) has the top that several spouts are suspended in sieve (1), continues during the sizing screening perlite ore to be sprayed water on the ore in sand form that sieves on (1) by several spray orifices (9).
