三产品密封螺旋重介质分选机  Three-product sealed spiral heavy medium sorting machine
(一) 技术领域 (1) Technical field
本专利涉及一种重介选矿设备, 特别涉及一种三产品密封螺旋重 介质分选机。  This patent relates to a heavy medium dressing equipment, and more particularly to a three product sealed spiral heavy medium sorting machine.
(二) 背景技术  (2) Background technology
目前现有的重介选矿设备中, 有重介斜 (立) 轮分选机、 重介浅 槽、 重介质旋流器几种。 其中重介斜 (立) 轮分选机、 重介浅槽多用 于大粒度物料的粗选, 另外, 由于其重量大、 占空间较太、 有运转部 件、 分选速度低等缺点, 近年逐步被重介质旋流器替代。  Among the existing heavy medium dressing equipments, there are several types of heavy medium inclined (vertical) wheel sorting machines, heavy medium shallow tanks, and heavy medium cyclones. Among them, heavy medium oblique (vertical) wheel sorting machine and heavy medium shallow groove are mostly used for rough selection of large-grained materials. In addition, due to its large weight, space occupation, running parts, low sorting speed, etc., it has gradually improved in recent years. Replaced by a heavy medium cyclone.
然而重介质旋流器腔内流体流动受其腔内空气柱影响而紊乱, 可 控性差, 其分割面扭曲、 排料模糊, 在同等入选原料的前提下, 分选 精度较重介斜 (立) 轮分选机、 重介浅槽低; 当入料性质 (密度分布 等) 变化比较大时, 只能通过繁杂的更换排料口, 甚至更换设备主体 来解决, 对入选原料的适应性比较窄。  However, the fluid flow in the cavity of the heavy medium cyclone is disturbed by the air column in the cavity, and the controllability is poor. The split surface is distorted and the discharge is fuzzy. Under the premise of the same raw materials, the separation precision is heavier. The wheel sorting machine and the heavy medium shallow trough are low; when the feeding property (density distribution, etc.) changes relatively large, it can only be solved by complicated replacement of the discharge opening, or even replacement of the main body of the equipment, and the adaptability of the selected raw materials is compared. narrow.
况且, 单台的旋流器无法真正实现三产品分选。 现在流行的 "三 产品旋流器" 实际上全称应为 "两产品两段旋流器组系统", 它是由 两台旋流器串联而成的。  Moreover, a single cyclone cannot truly achieve three product sorting. The popular "three-product cyclone" is actually called "two-product two-stage cyclone system", which is a series of two cyclones.
(三) 发明内容  (3) Invention content
本专利为了弥补现有技术的不足, 提供了一种总体结构简单、 重 量轻、 占地小的三产品密封螺旋重介质分选机。  In order to make up for the deficiencies of the prior art, the patent provides a three-product sealed spiral heavy medium sorting machine with simple overall structure, light weight and small footprint.
本专利是通过如下技术方案实现的:  This patent is implemented by the following technical solutions:
一种三产品密封螺旋重介质分选机, 其特征在于: 包括设置入料 口和出料口的密封螺旋管, 以及入口与出料口连通的分割器, 分割器 内部由两块产品隔板分为三部分, 两产品隔板前端均铰接有位于分割 器入口的分割刀, 分割刀架设于调节丝杠上。  The utility model relates to a three-product sealing spiral heavy medium sorting machine, which is characterized in that: a sealing spiral tube which is provided with a feeding port and a discharging port, and a splitter which is connected with the inlet and the discharging port, and two product partitions inside the divider Divided into three parts, the front end of the two product partitions are hinged with a dividing knife at the inlet of the divider, and the dividing knife holder is arranged on the adjusting screw.
本专利利用介质流 (内含待分选原料) 在密封的螺旋管空间内高 速流动, 靠离心力使物料按密度高低而分层, 在螺旋管路末端设置可 调式排料分割器, 从而实现物料的一次性三产品精确分选。 螺旋管根据入选原料的粒度大小确定其截面尺寸, 由入选原料密 度分布所决定的可选性难易程度来确定螺旋管的匝数, 根据供料的速 度配制决定螺旋的回转半径; 分割器中分割刀的角度由介质流速决 定, 两分割刀的开度由入选物料的可选性决定, 并由对产品质量要求 来调整分割刀的位置。 通过对入选原料进行浮沉实验分析, 配合现场 操作测试经验, 将各参数调到最佳状态, 就可实现物料的一次性高精 度三产品分选。 The patent utilizes a medium flow (containing the material to be sorted) to flow at a high speed in the sealed spiral tube space, and the material is layered according to the density according to the centrifugal force, and an adjustable discharge divider is arranged at the end of the spiral pipeline to realize the material. The one-time three products are precisely sorted. The spiral tube determines the cross-sectional size according to the size of the selected raw material, determines the number of turns of the spiral tube by the degree of selectivity determined by the density distribution of the selected raw material, and determines the radius of gyration of the spiral according to the feeding speed; The angle of the splitting knife is determined by the flow rate of the medium. The opening of the two-parting knife is determined by the selectivity of the selected material, and the position of the dividing knife is adjusted by the quality requirements of the product. Through the analysis of the floating and sinking experiments of the selected raw materials, combined with the field operation test experience, the parameters can be adjusted to the best state, and the one-time high-precision three-product sorting of the materials can be realized.
所述分割器被分割的三部分底端均设置有连通产品收集室的产 品出口, 将分割的三产品分别收集, 及方便后续的脱介系统进一步处 理。  The splitter is divided into three parts, the bottom end is provided with a product outlet connected to the product collection chamber, the divided three products are separately collected, and the subsequent de-intermediation system is further processed.
因为离心力场作用的同时, 还有重力场的影响, 所以, 轻、 重产 物与中间密度物之间的分界面不是严格垂直的, 因此, 两分割刀的布 置也存在一个偏角其偏离重垂线的角度 a可作如下设计:  Because the centrifugal force field acts at the same time, there is also the influence of the gravitational field. Therefore, the interface between the light and heavy products and the intermediate density is not strictly vertical. Therefore, the arrangement of the two-division knives also has a declination which deviates from the sag. The angle a of the line can be designed as follows:
a=arctg(g/(u2/r))= arctg(gr/u2) , 其中, a为分割刀的偏角, g为当 地的重力加速度, u为介质流的线速度, r为螺旋管的回转半径。 a=arctg(g/(u 2 /r))= arctg(gr/u 2 ) , where a is the declination of the splitting knife, g is the local gravitational acceleration, u is the linear velocity of the medium flow, r is the spiral The radius of gyration of the tube.
由于设备采用了螺旋管路, 物料在高速圆周运动中产生的离心力 使物料在运动过程中, 高密度产物向管路外侧移动, 低密度物料向管 路内侧移动, 从而实现按密度高低迅速分离。 由于是在密封的螺旋管 路腔内, 所以高、 低密度物料层分界面比旋流器要规范、 清晰。 由于 采用了可调式排料分割器, 使排料更加规范, 消除了重介质旋流器因 腔内空气柱与流体相互干扰、 流动杂乱而产生的分割面扭曲、 排料模 糊造成的分选指标难以有效控制的缺点。 另外, 由于传统的旋流器底 流口和溢流口是不可调的, 所以当入选原料性质 (主要是密度分布情 况) 发生较大变化时, 只能等到停车后, 通过更换直径不同的底流口 或溢流口来适应。 而本专利的三产品密封螺旋重介质分选机由于配置 了可调式排料分割器, 可在生产过程中随时调整, 工艺操作简单、 方 便、 快捷, 对原料的适应性大大增强。  Since the equipment adopts a spiral pipeline, the centrifugal force generated by the material in the high-speed circular motion causes the high-density product to move to the outside of the pipeline during the movement, and the low-density material moves to the inner side of the pipeline, thereby achieving rapid separation according to the density. Because it is in the sealed spiral tube cavity, the interface between the high and low density material layers is more standardized and clear than the cyclone. Due to the use of the adjustable discharge divider, the discharge is more standardized, eliminating the sorting index caused by the distortion of the split surface and the blurring of the discharge due to the interference between the air column and the fluid in the cavity and the flow disorder of the heavy medium cyclone. The disadvantage of being difficult to control effectively. In addition, since the bottom and the overflow of the conventional cyclone are not adjustable, when the nature of the selected raw materials (mainly the density distribution) changes greatly, it can only wait until the parking is stopped by replacing the bottom outlets with different diameters. Or overflow to adapt. The three-product sealed spiral heavy medium sorting machine of the patent can be adjusted at any time during the production process due to the configuration of the adjustable discharge divider, and the process operation is simple, convenient and quick, and the adaptability to raw materials is greatly enhanced.
本专利总体结构简单, 重量轻、 占地小、 无运转部件。 在分选效 率、 能耗、 管理难度等多方面, 比重介斜 (立) 轮分选机、 重介浅槽 都要优越的多。 (四) 附图说明 The overall structure of the patent is simple, light weight, small footprint, and no moving parts. In terms of sorting efficiency, energy consumption, management difficulty, etc., the proportion of the slanting (vertical) wheel sorting machine and the heavy medium shallow tank are much superior.
