试验室CGZH型浮选柱技术参数
Technical Parameters of laboratory flotation column technology parameters

本产品是近几年来我厂有关人员在不断实践的基础上，自行研制、开发的一种节能、高效、环保型快速式浮选机。

This machine is a kind of energy-saving, high-efficiency, and pollution-free flotation machine developed by relevant persons in our factory in recent years during their constant practice.

本产品具有占地面积小，能耗低，操作简单，维修量小，处理量大，精煤回收率高等特点。并且一般情况下浮选精煤灰分可根据合同需要在6％-12％之间随意调整，尾煤灰分可达45％-70 ％之间，可从吨煤泥中提取60％-90％之间的合格精煤。

This product has characteristics such as small occupying land, low energy consumption, easy operation, infrequent maintenance, large handling capacity, and high recovery rate of concentrate. Besides, the ash content of flotation concentrate can normally be adjusted freely within 6% to 12% according to contract needs. The ash content of tailings can be adjusted within 45% to 70%. A total of 60% to 90% of qualified concentrate can be extracted from the coal slime.

正常情况下，浮选精煤数量约占洗精煤产量的10％左右。

In most cases, the amount of flotation concentrate accounts for around 10% of that of the fine washing coal.

一、用途

I. Application

该设备主要用于从洗煤水中提取精煤，适用于和15平方以下的所有跳汰洗煤机、侧鼓式洗煤机、筛下空气室洗煤机配套使用。

This equipment is mainly used to extract clean coal from the coal washing water, and can be used with all jig coal washers, side-drum coal washers, and air chamber underbed coal washers occupying less than 15m2.

二、结构特征

II. Structural Feature

该设备占地小，每台占地仅需6-7×6-7（㎡）;易操作，每台每个班仅需一人；维修量小，仅有两台泵的保养与维修；电耗低，配套功率在50-100千瓦之间。

Such equipment occupies a small land, only 6-7×6-7（㎡） for each, and is easy to operate. Only one person is enough to operate each of such machines in one shift. Only two pumps need to be maintained. It does not consume much power and its rated power is 50 – 100KW.

洗水无须浓缩，即可将浮选设备串入洗煤系统中进行正常生产（可节约浓缩设备投资25万元左右）。

The washing water does not need to concentrate and the flotation equipment can be put in the coal washing system for normal production (Around RMB 250,000 spent purchasing concentrator can be saved).

三、工作原理

III. Working Principle

打开上料泵后，洗煤水先经过预处理器，使经注药器滴入的起泡剂和捕收剂与洗煤水充分混合。

After the feed pump is started, the coal washing water first flow through the preprocessor, to get the foaming agent and suction supporting agent dripped from the reagent injection instrument to be intensively mixed with the coal washing machine.

进入浮选柱体内的洗煤水，由上而下与由下向上运动的泡沫，发生连续不断的充分碰撞，从而完成了从粗选到精选再到扫选的三个过程。

The coal washing water getting into the flotation column from top to bottom collides continuously with the bubbles moving from bottom to top, so as to finish three processes from roughing, to cleaning, and then to scavenging.

经过以上三个过程未能充分上浮的精煤，从柱体底部进入循环系统，通过强制循环，使一少部分经扫选后仍未浮上的精煤，经运动、充气、再混合后，伴随气泡充分上浮，使系统效果更趋完善。

The clean coal which is not able to fully float after these three processes enters the circulating system from the bottom of the column. Through forced circulation, a small part of the clean coal which does not float fully floats upward along with the bubbles after movement, aeration, and mixing again, to enable the system to be more effective.
