CGS型細砂回收裝置 Fine sand recovery unit

一、工作原理

1、結構：由電機 、碴漿泵、泥砂分離器、ZKR直線振動篩、清洗槽、返料箱等到組成。

2、工作過程：泵將砂水混合物輸送至泥砂分離器，離心分級濃縮的細砂經沉砂嘴提供給振動篩，經振動篩脫水后，細砂與水有效分離，少量細砂、泥等經返料箱再回到清洗槽，清洗槽液面過高時，經出料口排出。直線振動篩回收物料重量濃度為70%—85%。調節細度模數可通過改變泵轉速、改變砂漿濃度、調節溢流水量、更換出砂嘴來實現。從而完成清洗、脫水和分級三種功能。

二、特點及優勢

1、傳統人工砂濕法工工藝中，人工砂的洗泥、脫水采用螺旋洗砂機，人工砂中細砂的流失幾乎不能控制。采用該細砂回收系統，可以有效降低細砂的流失量，使其控制在5—10%之內。很好地解決了人工骨料加工系統中出現的成品砂細度模數偏高、石粉含量偏低的難題。

2、振動篩采用聚氨酯篩網，聚氨酯篩網較其它類型篩網壽命更長，且不易堵孔。

3、泥砂分離采用聚胺脂整體澆鑄成形，提高了整個裝置的使用壽命，可順利完成料漿濃縮、液體澄清等工作。

4、****可回收排放總量中85%—90%的細顆粒物料具有其他設備無可比擬的技術和經濟優勢

5、細粒得到充分回收，減少了沉淀池的工作量，降低了沉淀池的清理成本；

6、減少了細料自然堆放時間，可直接轉運，供應市場。

7、可根據用戶的不同要求，設計相應的解決方案。

I. Work Principle

1. Structure: This equipment is composed of motor, slurry pump,  sand slime separator, ZKR line vibrating screen, rinse tank, and revert box.

2. Working process: The pump conveys the sand and water mixture to  the sand slime separator. The fine sand after centrifugal classification and  concentration is supplied to vibration screen through the underflow exit. After  dewatered by the vibration screen, the fine sand and water are effectively  separated. A small amount of fine sand, mud, etc goes back to the rinse tank  through the revert box. When the liquid level of rinse tank is too high, the  find sand is discharged from the discharge opening. The weight concentration of  materials recycled by line vibrating screen is 75% to 85%. The adjustment of  fineness modulus can be realized through the change of pump speed, change of  mortar concentration, regulation of overflow water amount, and replacement of  sand blast nozzle so that the three functions, i.e. washing, dewatering and  classification can be fulfilled.

II. Characteristics and Advantages

1. In traditional wet processing of artificial sand, screw sand  washer is adopted for mud removal and dewatering of artificial sand. The fine  sand in the artificial sand can hardly be prevented from being washed away.  With such fine sand recovery system, the amount of fine sand washed away can be  effectively reduced. The ratio of fine sand washed away can be kept within 5-10%.  It well solves the problems of high fineness modulus of finished sand and low  content of stone powder in the artificial aggregate processing system.

2. Vibrating screen adopts polyurethane screen. Compared with  other types of screen, polyurethane screen has longer service life and is not  easily blocked.

3. The sand slime separator adopts polyurethane for overall cast  form which helps to prolong the service life of the whole unit. Slurry  concentration, liquid clarification, etc can be finished smoothly.

  4. It can recover 85% to 90%  of the total discharged fine particle materials, thus having incomparable  technological and economic advantages not enjoyed by other kinds of equipment.

5. Fine grains are fully recovered. The work load of sedimentation  tank is decreased and costs spent in cleaning sedimentation tank are reduced.

6. The natural storage time of fine materials is reduced. They can  be directly transported to be supplied in the market.

7. Different solutions can be designed according to different  requirements of customers.
