The lower section of subassembly, the bottom of the sieve chamber;Comprising a rotating shaft, a set of bearing, an electricity in Screen assemblies described in each group
If machine and dry sieving disk, if dry sieving disk is equidistantly fixed in the rotating shaft, and the rotating shaft is each screening
The symmetry axis of disk, one end of the rotating shaft are rotatably connected on the side of the sieve chamber, and the other end of the rotating shaft passes through bearing
It is rotatablely connected with motor, it is arranged in a crossed manner between the screening disk in two adjacent groups Screen assemblies.
Preferably, the rotation direction that disk is sieved described in each group is identical.Rotation direction is identical to be advantageous to larger thick of particle
Coal focuses on most edge, is easy to collect, and effectively prevents rough coal blocking screen cyclotomy piece.
Preferably, the spacing between each rotating shaft is adjustable.Tune is realized by adjusting the spacing between two neighboring rotating shaft
The gap between western two adjacent groups screening disk is saved, reaches the purpose that control screens out the duff granularity come;If it is intended to sieve
The duff granularity branched away is smaller, then turns the spacing between two neighboring rotating shaft down, such two adjacent groups screening disk it
Between gap just diminish, screen out come duff particle it is just smaller, it is on the contrary then screen out duff granularity it is larger.
Beneficial effect:For the utility model when being sieved to wet coal, wet coal to be sieved falls on sieve intracavitary from feeding mouth
Screen assemblies on after, the rotating shaft in each Screen assemblies rotates in the same direction, drives screening disk thereon also same
Direction rotates, and the rotation of each group screening disk causes the duff of relatively fine particle in wet coal to fall from the gap between screening disk two-by-two
To sieve bottom of chamber portion, then through duff export discharge, the larger rough coal of particle due to can not from two-by-two sieve disk between gap
Fall, then as the rotation of each group screening disk focuses on the screening disk position at most edge gradually, due to the screening at most edge
Gap between disk and sieve chamber is larger, and now the larger rough coal of granularity just drops down onto sieve bottom of chamber portion under the gap, then slightly
Coal is just exported through rough coal and discharged.Compared with directly carrying out screening to wet coal using the screen with screen cloth in the prior art, this reality
Traditional screen cloth is replaced using the screening disk rolled with new, can effectively avoid the larger coal cinder of particle from blocking screen,
While ensureing that screening out the coal particle come meets production needs, screening efficiency is greatly improved.
