1、附录 外文文献原文 About gravity qing separator is discussed some problems According to the content and gravity qing separator for dry bulk density, liquidity, choose the clear separation. This equipment often used in improving seed, grain,minerals and recycling material quality products. This paper stated t

2、he gravity clear how to work there, working with the use of material is gravity clear separator adapt, how to select the gravity qing separator, gravity qing separator mesa of the mixed zone seed treatment and gravity, there have a good clear investment prospects. If the material contains light impu

3、rity, mildew metamorphic seeds, weed seeds and heavy impurity,So can use gravity qing separator, through the material of it from the material in bulk density points To improve the material from out of the quality. For instance in processing seeds and grain process, do not The full, worms cracking se

4、eds (grain), not mature, mildew seeds (valley Content), weed seeds,Small stones from good seeds (grain) of separation of to improve Seed germination rate and clarity. However, not every kind of material can be gravity high efficiency in the qing qing separator choose points From, sometimes use many

5、sets of gravity when the qing qing separator material chosen separation effect is not obvious The. Here there how to work the gravity. How to determine whether the material and gravity Qing separator adapt. 1 there is clear how gravity 1. 1 gravity structure of qing separator 1. 1. 1Typical of the g

6、ravity qing separator by frameWith a sieve net, material of conducting bar torque Form vibration mesa (or triangle mesa), one or more Taiwan fan, wind room, feed hopper,Discharging system, CVT institutions. 1. 1. 2 general mesa change from 46 cm x 92 cm to 183 cmx457. 5 cm, mesa in two directions An

7、gle can be adjusted. 1. 1. 3 feeding device installed in the washing machine of gravity (at least for 15 minutes or more consecutive materials； next, mesa high above the edge. Feeding device may have condiment door， Through the material door can increase or decrease the mesa of material flow. Mesa h

8、ave three materials Row export, heavy material and light material row in feeding and export mouth relative low mesa Edge, of course, intermediate product material row in heavy material and export light material among export. 1. 1. 4 vibration device installed in the bottom of the table, a kind of ec

9、centric movement for vibration.A fan or a group of fans also be placed in the table below. Automatic control panel and laid it inMesa make handlers beside convenient to console the dip Angle, vibration frequency and windVolume. 1. 2 working principle 1.2.1 material layer At work, the material from b

10、unker eduction, flows through feeding device to gravity clear choice Machine woven nets mesa, mesa is mainly along the vertical vibration, mesa vibration frequency For 200 time/minutes to 600 times/minutes. The vibration of the mesa and air flow to make materials spread And a fluid state. Air throug

11、h the wind chamber spread to mesa on screen mesh, through the control gas Flow make mesa material produce the layer (and not light material be given heavier blow in material out), Heavy materials remain in mesa, light material in air under the action of floating in heavy leave mesa Material above. A

12、t this time the materials under layered area. Mesa material distribution in the material and guide Between article, help mesa materials uniform transition. 1. 2.2 things shake separation Vibration in two direction mesa have tilt, to promote material separation and discharging in Mesa material strati

13、fication, because the mesa vibration influence, mesa heavier particles due to the ground Wipe the force ACTS to mesa high edge mobile, heavy material on the mesa the crawling to mesa high Edge, and float in heavy material above the lighter particles, by gravity to lower edge mobile, So the material into a vertical stratification level separation. Heavy material over the edge of the mesa high living board The door, the outflow into heavy material row mesa export；
