Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] In the accompanying drawing, the concentrate produced in the process of mineral processing (ore dressing) enters the dehydration tank [3] by the concentrate slurry supply system [2] by pumping or gravity flow, and the solid minerals in the concentrate slurry are Its own physical characteristics sink into the bottom of the pool to form a concentrate deposit layer in the way of free settlement and interference settlement, and the liquid becomes supernatant water and is discharged from the adjustable overflow port [7] into the return water system [4] for recycling; The concentrate slurry continuously enters the dewatering tank [3], and the overflow port [7] needs to be adjusted randomly. When the overflow port [7] is adjusted to the upper limit and the overflow is mixed with fine-grained solid minerals that have not completely settled, the The conce...

Abstract

The invention provides a concentrate dehydrating technology and a device, which is composed of a set of dehydrating pools (3) with special devices (3) and a high pressure air supply system (1) which are manually matched, a dehydration task comprising three processes: settling dehydration, vibration dehydration and pneumatic dehydration, is completed by utilizing self characteristics of concentrate slurry. The concentrate slurry, after natural settling dehydration in the dehydrating pool (3), is blown into a bottom surface of the dehydrating pool (3) by a high pressure blast to generate a big blasting force and a big vibration force, to make solid particles be dehydrated from a hydration membrane package and generate settlement and compaction, and water is extruded out and blown into a water return system (4) by high pressure blast, thereby making a water content of a concentrate product reach a standard requirement. The concentrate product is loaded, transported and sold by a concentrate loading and transporting system (5). The technology and device has advantages of simple flow, small equipment, no intermediate material conveying and transferring link, no filtering medium, energy saving, consumption reduction and low labor intensity, is suitable for dehydration of the concentrate of various metal and nonmetal ores, and is suitable for large scale industrialization production.

Description

technical field [0001] The invention relates to a concentrate dehydration process and device in the mineral processing process, especially a process and device capable of removing the water wrapped in a hydration film in a fine-grained concentrate. The process and device are suitable for various metal and non-metallic minerals. Concentrate dehydration is suitable for large-scale industrial production. Background technique [0002] At present, the known mineral processing process concentrate dehydration process is mainly composed of three parts: concentration, filtration and filtrate treatment. Most of the concentration and filtration parts are completed by special equipment. Technical parameters such as blowing pressure and blowing pressure have strict requirements, so the process flow is complex, operation control is difficult, the water content of the concentrate product is difficult to meet the standard, and the energy consumption is large and the production cost is high....
