Detailed Description
A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. The scope of the invention is not limited to the following examples, but is intended to be limited only by the appended claims and the equivalents and modifications thereof, which fall within the scope of the invention.
Referring to fig. 1-3, a screw conveyor with a vane wear-resistant layer capable of being compensated according to the invention comprises a barrel 2, a screw 1 penetrating into the barrel, and a driving device 3 fixed at the outer end of the barrel and in transmission connection with the screw, wherein a helical vane 7 wound along the axial direction of the screw 1 is fixed on the outer side surface of the screw; the driving device drives the screw to rotate in the cylinder body so as to convey a required medium from an inlet 21 arranged at one end of the cylinder body to an outlet 22 arranged at the other end of the cylinder body along the spiral blade, the spiral blade is positioned on the inner part of the cylinder body and is close to the outer end of the cylinder body, a plurality of limit screws 6 are sequentially fixed on the outer end of the cylinder body, a blade wear-resisting block 4 is arranged corresponding to each limit screw, a movable limit groove 41 is arranged on each blade wear-resisting block, the inner end of each blade wear-resisting block is sleeved outside the corresponding limit screw of the spiral blade and the limit screw is arranged in the movable limit groove, and a thrust spring 5 is arranged between each blade wear-resisting block and the outer end of the corresponding spiral blade.
The limiting screw is perpendicular to the two opposite outer side surfaces of the helical blade. The outer end face of the spiral blade is provided with a spring clamping groove, and the thrust spring is arranged in the spring clamping groove. The spiral blade is formed by sequentially connecting a plurality of small spiral blades, and a blade abrasion-resistant block is arranged on each small spiral blade. The blade wear-resisting block comprises a wear-resisting block body 42 and a supplementary wear-resisting block 43 arranged on the outer end surface of the wear-resisting block body.
In operation, the drive means 3 rotates the helical blade 7 within the barrel 2 to convey the desired medium along the helical blade 7 from an inlet 21 provided at one end of the barrel 2 to an outlet 22 provided at the other end of the barrel 2. Since the blade wear-resistant block 4 is directly contacted with the inner wall of the cylinder, and the thrust spring 5 is arranged between the blade wear-resistant block and the helical blade, when the blade wear-resistant block 4 is worn, the blade wear-resistant block 4 is lowered under the action of the thrust spring 5 to be pushed out so as to compensate the wear amount. In addition, because the limit screw 6 is movably limited in the movable limit groove 41 of the blade wear-resisting piece, when the blade wear-resisting piece moves outwards for a certain distance, the blade wear-resisting piece can not move outwards any more due to the effect of the limit screw, so that the limit screw can limit the maximum wear amount of the wear-resisting piece and the wear-resisting piece is prevented from falling off during super wear.
In the invention, after the blade wear-resistant block, the thrust spring, the limit screw and other accessories are damaged, the blade wear-resistant block, the thrust spring, the limit screw and other accessories can be directly replaced at a construction site, the original design size is recovered, the maintenance of a factory is not required, and complicated processes such as cutting, polishing and welding are not required, so that the maintenance is safe and reliable, and the maintenance is simple and quick.
Therefore, the blade wear-resistant block capable of being automatically compensated is arranged on the spiral blade, when the wear-resistant block is worn, the blade wear-resistant block can automatically withdraw through the thrust spring to compensate the wear quantity, so that the service life of the spiral blade is greatly prolonged, the stable working efficiency of the spiral blade is kept, and when the wear-resistant block is damaged, the spiral blade wear-resistant block can be directly replaced on a construction site, and the spiral blade wear-resistant block is safe, quick and reliable, and avoids the problems of difficult maintenance, long construction period and the like in the existing work.
