Sinonine improves the bearing structure of spiral sand washing machine

Sinonine improves the bearing structure of the tail part of the spiral sand washing machine, which makes the spiral sand washing machine work better in the mixed water and improves the service life of the equipment.
 
In the traditional spiral sand washing machine, the tail bearing seat is either tail lifting or external bearing seat. Because the tail part of the spiral sand washing machine is working in the mixed water, the existing tail bearing pedestal often suffers from water leakage and sand feeding, and the main shaft of the spiral sand washing machine often fails. This kind of fault seriously affects the smooth progress of sand washing plant, often makes the whole sand washing production line stop for maintenance, resulting in greater economic losses. Therefore, the structural form of the bearing pedestal at the tail of the existing spiral sand washing machine is an urgent technical problem to be solved.




In order to overcome the shortcomings of the existing technology, Sinonine designs a kind of rear bearing seat that can be sand proof and water-proof, to ensure that the rear bearing will not be damaged during the operation, to greatly reduce the maintenance and shutdown time, and to improve the production efficiency of the spiral sand washing machine.

The structural design is completed by the following measures:

The rear end shaft in the rear end bearing block assembly of the spiral sand washing machine is fixed by the hoop, and the front and rear two plates of bearings are installed on the rear end shaft. The shape of the rear end bearing block is a cylinder with flange plate at the tail, and the front and rear two plates of bearings are installed in the cylinder of the bearing block. The front end of the rear end bearing seat is sealed by a water seal cover, while the rear end bearing seat is sealed by a water seal seat with a J-type oil seal. The whole rear end bearing seat assembly is sheathed in the spiral shaft tube of the spiral sand washing machine, and is fixed together with the spiral shaft tube through the flange plate on the rear end bearing seat.
 
When the spiral sand washing machine works, the whole rear end bearing seat assembly is hidden in the spiral shaft tube, and will not be damaged by sand and water.



The following  is the structural drawing of the modified rear bearing pedestal assembly:



Through the above structural improvement, the rear bearing seat of the spiral sand washing machine can effectively prevent sand and water, and completely solve the technical problem of bearing damage caused by water inflow into sand. In this way, the stability of the whole machine is guaranteed, the shutdown time is reduced, the production efficiency is improved, and the service life of the spiral sand washing machine is prolonged.
