1、<p>  About gravity qing separator is discussed some problems</p><p>  According to the content and gravity qing separator for dry bulk density, liquidity, choose the clear separation. This equipment of

2、ten used in improving seed, grain,minerals and recycling material quality products. This paper stated the gravity clear how to work there, working with the use of material is gravity clear separator adapt, how to select

3、the gravity qing separator, gravity qing separator mesa of the mixed zone seed treatment and gravity, there have a good clear investment prospects.</p><p>  If the material contains light impurity, mildew me

4、tamorphic 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 proce

5、ssing seeds and grain process, do not The full, worms cracking seeds (grain), not mature, mildew seeds (valley Content), weed seeds,Small stones from good seeds (grain) of separation of to improve Seed germination rate a

6、nd clarity</p><p>  However, not every kind of material can be gravity high efficiency in the qing qing separator choose points From, sometimes use many sets of gravity when the qing qing separator material

7、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.</p><p>  1 there is clear how gravity</p><p

8、>  1. 1 gravity structure of qing separator</p><p>  1. 1. 1Typical of the gravity qing separator by frameWith a sieve net, material of conducting bar torque Form vibration mesa (or triangle mesa), one or

9、 more Taiwan fan, wind room, feed hopper,Discharging system, CVT institutions.</p><p>  1. 1. 2 general mesa change from 46 cm x 92 cm to 183 cmx457. 5 cm, mesa in two directions Angle can be adjusted.</p

10、><p>  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 t

11、he material door can increase or decrease the mesa of material flow. Mesa have three materials Row export, heavy material and light material row in feeding and export mouth relative low mesa Edge, of course, intermediate

12、 product material row in heavy material and export light material among expor</p><p>  1. 1. 4 vibration device installed in the bottom of the table, a kind of eccentric movement for vibration.A fan or a gro

13、up 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.</p><p>  1. 2 working pr

14、inciple</p><p>  1.2.1 material layer</p><p>  At work, the material from bunker eduction, flows through feeding device to gravity clear choice Machine woven nets mesa, mesa is mainly along the

15、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 through the wind chamber spread to mesa on sc

16、reen mesh, through the control gas Flow make mesa material produce the layer (and not light material be given heavier blow in materia</p><p>  1. 2.2 things shake separation</p><p>  Vibration i

17、n two direction mesa have tilt, to promote material separation and discharging in Mesa material stratification, because the mesa vibration influence, mesa heavier particles due to the ground Wipe the force ACTS to mesa h

18、igh 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 stratifica

19、tion level separation. Heavy material over the edge of the </p><p>  1. 2. 3 material choose clear separation is the premise of material layer, material layered regional general From feed mouth began to no m

20、ore than a third of the mesa, only the material fully stratification, just Can make different density of material completely separate.</p><p>  1. 2. 4 material into the gravity there must be approved by a c

21、lear before the washing to remove material in the screen Most of the chaff, leaf stalks and big miscellaneous, then into the gravity of the separator basic materials On similar appearance, just on the density change.<

22、/p><p>  2 how to choose a gravity clear there</p><p>  In determining the material of the gravity clear the adaptability of the separator, the next step is to content Material in clear on the grav

23、ity there, to determine the most suitable for the gravity of the material washing qing.</p><p>  2. 1 provide sample</p><p>  The premise of the test is to provide adequate test first material s

24、ample. For big The gravity model clear separator, need to provide several tons of material make it can pack to gravity clear store there After the storehouse for feeding and processing, gravity for lab sorting machine, y

25、ou are required to offer 57g Or so the material sample.</p><p>  2.2 analysis gravity clear separation of the good material washing and abandon material sample </p><p>  (1) good material qualit

26、y whether meet your requirements, material quality improvement of process How degrees. (2) rejected material is how many, rejected material in the content of good material How much畚 The machining process of good material

27、 in the future if can recycle. (3) as gravity qing separator try Check the results, and the material quality be dropped, the quality descend the reason is to adjust (such as mesa vibration Still need to reduce) or storag

28、e, material feeding device, Discharg</p><p>  2.3 the material mouth was different materials bulk density</p><p>  Through the determination of the material KouChong different material and light

29、 material differences reflect gravity qing The qing choose washing effect. For seed batch of speaking, in the determination of bulk density, meanwhile, the different Material of the seed germination rate and mouth clarit

30、y in a seed checkout room.</p><p>  3 Gravity qing separator mixed zone materials handling</p><p>  3.1 the T-shirt material by gravity after washing the intermediate product material (about 20%

31、 or so) The problem is more trouble between. According to domestic common practice is intermediate product materials for again The gravity of the separator feeding mouth. Gravity enter the homework after washing the stat

32、e, each unit Several are stable, by gravity of intermediate product material clear separator, the second time There is a clear gravity in the form of intermediate product material discha</p><p>  3.2 foreign

33、 to this problem puts forward more objective practice, they say the feeling Often appear in the form. General intermediate product material by heavy small materials and light big materials group Become, will intermediate

34、 product materials into the wind to screen the separator (and not gravity feed entrance qing Separator entrance) hello again a screening and, to some extent, improve the physics properties of materials (xi 1, form Size),
