Problems solved by technology

[0004] Currently, hydrocyclones and filter presses are mainly used for the grading and dehydration equipment of the tailings silo. In actual use, due to problems such as high energy consumption, complicated operation process, low output of finished products, inability to continuously feed materials, and prone to mechanical failures, etc., make it unable to meet the needs of large-scale production

Embodiment Construction

[0019] specific implementation

[0020] In order to further describe the present invention, the following is a further detailed description of a graded sand extraction conveying system for tailings reuse in tailings ponds according to the present invention in conjunction with the accompanying drawings and embodiments.

[0021] Depend on figure 1 Shown is a structural schematic diagram of a graded sand-taking conveying system for tailings pond tailings reuse in the present invention and combined with figure 2 , image 3 It can be seen that in practical application, the tailings in the tailings pond are fed into the tailings classification and sand removal equipment through the sand pump and the tailings conveying pipe - the feed port of the special spiral classifier for tailings classification and sand removal. , the sand is classified and taken by the spiral classifier, and the tailings (that is, the coarse-grained part, accounting for about 80% of the tailings) is discharg...

Abstract

The invention discloses a graded sand taking and conveying system used for tailing reuse of a tailing pond. The system consists of a tailing input unit, a tailing grading and sand taking unit, a tail sand conveying unit, and a tail sludge output unit, wherein the tailing input unit consists of a sand pump and an input pipeline; the tailing grading and sand taking unit comprises a spiral grader special for tailing grading and sand taking; the tail sand conveying unit is a belt conveyor; and the tail sludge output unit consists of the sand pump and a tail sludge output pipeline. The distance between spiral leaf boards of the spiral body of the spiral grader is 290 to 320mm; the ratio of the height h of a downflow weir of a groove body to the spiral diameter D of the spiral body is between 1.2 and 1.4; the gradient of the groove body is 19 to 21 degrees; a motor adopts a frequency-variable speed-regulating motor; and the spiral leaf boards of the spiral body are made of manganese steel. The system can realize sand taking, grading and dewatering of the tailing pond; the reliability is high; the system is convenient to operate; product yield is higher; material can be fed continuously;and the requirement on large-scale production can be met.

Description

technical field [0001] The present invention relates to a graded conveying system, in particular to a graded sand taking conveying system for tailings tailings reuse in tailings ponds, especially suitable for application in various types of sand taking systems for tailings ponds in mine concentrators using magnetic separation technology, Realize tailings size classification, desliming, dehydration and other operations, and complete tailings sand extraction. Background technique [0002] In the process of development and utilization of mineral resources, limited by human beings' awareness of resources, technical level of development and utilization, policy factors, etc., most of them are stored in tailings ponds in the form of tailings, and even returned to the natural environment . Not only has it caused a huge waste of limited resources, occupied land, and invested heavily, it has also brought serious environmental and safety problems, and it is also a major source of dang...
