Beach sand shaking table concentrate high efficiency dehydrating predrying continuous production system and method

Abstract

The invention discloses a beach sand shaking table concentrate high efficiency dehydrating pre-drying continuous production system, and a method. The system comprises a concentrate collecting pool used for collecting shaking table concentrate, a high-frequency vibrating screen, a filtering and pre-drying all-in-one machine, a conveying belt, a drying ore feeder, a hydrocyclone and a reuse water pool; the filtering and pre-drying all-in-one machine comprises a horizontal vacuum belt filter, an air entraining cover and a standby heat source generator; the horizontal vacuum belt filter is connected with the drying ore feeder through the conveying belt; the drying ore feeder is connected with a drying machine; and the drying machine is connected with the horizontal vacuum belt filter so that tail gas of the drying machine can flow back to a filter belt of the horizontal vacuum belt filter. Pre-drying, dewatering and filtering procedures are designed to be continuously carried out or partially overlapped, tail gas waste heat of an existing single-cylinder dryer of enterprises is fully utilized, tail gas is introduced into the horizontal vacuum filter to be pre-dried, the moisture content of filter residues can reach 6% or below, the dewatering efficiency is effectively improved, the production cost and energy consumption are reduced, and the in-plant environment quality is improved.

Description

technical field [0001] The invention belongs to the technical field of mineral processing equipment, and in particular relates to a continuous production system and method for high-efficiency dehydration and pre-drying of concentrated ore on a seashore sand shaking table. Background technique [0002] At present, the degree of automation in the collection, dehydration, and drying of the rough concentrate in the shaking table concentrate is not high, and most of them are manually operated. After dehydration and air drying in natural air drying, it is then dried in a single cylinder dryer. Shaker concentrates are conveyed by manually operated forklifts during the transportation process from the drying yard to the indoor temporary storage yard, and from the temporary storage yard to the feeder in front of the drying cylinder, which has high labor intensity, low efficiency, and much dust in the workshop; air-drying The speed is greatly affected by weather, temperature, etc., wh...

[0002] At present, the degree of automation in the collection, dehydration, and drying of the rough concentrate in the shaking table concentrate is not high, and most of them are manually operated. After dehydration and air drying in natural air drying method, it will be dried in a single cylinder dryer

Shaker concentrates are conveyed by manually operated forklifts during the transportation process from the drying yard to the indoor temporary storage yard, and from the temporary storage yard to the feeder in front of the drying cylinder, which has high labor intensity, low efficiency, and much dust in the workshop; air-drying The speed is greatly affected by weather, temperature, etc., which seriously affects the continuity of the subsequent sections; the drying yard and storage yard occupy a large area, and there is a lot of dust, resulting in waste of land and environmental pollution
