The utility model content
The purpose of this utility model is to improve on the basis of existing technology, proposes a kind of aeration type final election and revolves the sieve that shakes.Can filter out the solid particle of appropriate particle size with realization, and can be to its preactivated purpose of ventilating.
Overall technical architecture of the present utility model is:
The sieve that shakes is revolved in the aeration type final election, comprise shell 5, be arranged at the elastic base 7 and the driving mechanism 10 of shell 5 bottoms, be arranged at intervals at the two-layer at least screen cloth 3,11 in the shell 5 vertically, and the charging aperture 4 and the discharging opening that are opened in shell 5 tops and each layer screen cloth 3,11 cavity sidewalls of being separated; Described shell 5 tops are provided with air inlet 2 and are communicated with inner chamber; Except that charging aperture 4, discharging opening, air inlet 2, shell 5 is an airtight cylindrical cavity.
Concrete technical construction of the present utility model also has:
The air-tightness of shell 5 inner chambers should satisfy-0.05MPa～+ requirement of 0.05MPa.
Even for the vibration that guarantees complete machine, the preferred construction mode is that elastic base 7 distributes along shell 5 equal angles.
For ease of the making and the processing of complete machine, satisfy bubble-tight requirement simultaneously, the preferred construction mode is, folder is established and is fixed with sealing ring 9 between the lower side of each layer screen cloth 3,11 and adjacent shell 5 sidewalls.
More the preferred construction mode is, adopts bolt 8 immovable fitting between shell 5 top and bottoms.Can further strengthen the structural strength of shell 5 like this, and be fit to the needs of its pressure-bearing; Can it is evident that bolt 8 equal angles between shell 5 tops and pairing bottom is uniform to be that best technical construction is selected.
For the solid particle to different-grain diameter sieves, discharging opening is including, but not limited to adopting following structure, and discharging opening comprises coarse fodder discharging opening 1, fines discharging opening 12, the accept discharging opening 6 that is opened in each layer screen cloth 3,11 shells of being separated 5 internal cavity sidewalls.
The obtained technological progress of the utility model is:
The utility model improves on the basis of existing technology, not only can realize sieving the solid particle of appropriate particle size, can also ventilate to the solid particle in the screening process simultaneously and activate in advance, satisfying in the complicated heterogeneous reaction system requirement, thereby make reaction be easy to control to the solid reaction particle.
