Description
Technical Field
The utility model relates to a screw conveyer technical field specifically is screw conveyer of independent blade.
Background
The traditional screw conveyor blade is generally manufactured in a split mode, and a single blade is assembled into a whole in a welding mode and then welded on a screw shaft; the integral blade is easy to deform integrally or a plurality of blades fall off due to crack of a welding seam in the using process; meanwhile, once a serious jamming situation occurs in the operation process, for example: when the spiral conveyor is used for conveying flue gas fly ash below the deacidification tower or the quench tower, a certain amount of cooling water needs to be sprayed in the operation process of the deacidification tower or the quench tower, wherein a part of the cooling water is absorbed by the flue gas fly ash and then falls into the spiral conveyor along with the flue gas fly ash, and the other part of the cooling water is accumulated in a cone bucket section of the deacidification tower or the quench tower, so that the flue gas fly ash accumulated in the cone bucket section can be hardened, and the hardened flue gas fly ash falls into the spiral conveyor in a blocky state after being vibrated by a rapping device arranged on the cone bucket section of the deacidification tower or the quench tower, so that the blockage of the spiral conveyor can be easily caused;
when the problems of blade deformation, falling caused by weld joint crack, jamming of a screw machine and the like occur, the later-stage maintenance method for the integral blade in the prior art needs to integrally replace the blade after the whole screw shaft is disassembled; not only the operation is complicated, but also the cost is higher.
Disclosure of Invention
In order to solve prior art, screw conveyer blade maintenance complex operation, the higher problem of cost, the utility model provides a screw conveyer of independent blade, its maintenance method is simple, and cost of maintenance is cheap, can reduce the probability that screw conveyer broke down simultaneously.
The technical scheme of the utility model is like this: an individual blade screw conveyor comprising: the spiral shaft is provided with a blade structure arranged on the spiral shaft; the method is characterized in that: the blade structure comprises independent blades and a blade handle, wherein the blades are fixedly connected with the blade handle; the screw shaft is provided with a mounting hole penetrating through the diameter of the shaft, and the petiole penetrates through the mounting hole and is fixed on the screw shaft through a nut;
each independent blade is arranged on the screw shaft through different inclination angles, and the integral form formed by all the arranged blades is a spiral belt-shaped conveying blade surrounding the screw shaft.
It is further characterized in that:
the blades are fan-shaped;
the petiole is quadrangular; the shape of the inner cavity of the mounting hole is matched with that of the blade handle;
gaps are reserved between the adjacent blades;
the side wall of the blade is provided with a double-sided chamfer;
a fastener is arranged between the nut and the main shaft; the fastener includes: outer tongue lock washer, elastic washer.
The utility model provides a spiral conveyer with independent blades, which forms a conveying blade with a spiral belt shape as a whole through the independently installed blades, and once a fault occurs and the maintenance is needed, only the blade with the fault needs to be replaced and maintained; when in maintenance and replacement, the independent blade can be maintained and replaced by disassembling the nut and drawing out the blade handle from the mounting hole of the spiral shaft; the blade installation mode based on the blade handle not only reduces the probability of blade falling in the use process, but also has simple operation of disassembly and installation and reduces the later maintenance cost; meanwhile, gaps are reserved between adjacent blades, so that small blocky materials can pass through the gaps conveniently, and the probability of clamping of the screw machine is reduced; the lateral wall of blade sets up two-sided chamfer, is provided with the space between the adjacent blade simultaneously, and in the use, the edges and corners and the side of blade lateral wall can effectively be broken to great cubic material, has further reduced the possibility that the spiral machine took place the jam trouble.

Detailed Description
As shown in fig. 1 and 2, the present invention relates to a screw conveyor with independent blades 2, which includes: the screw shaft 1 and the blade 2 structure are arranged on the screw shaft 1; the blade 2 structurally comprises an independent blade 2, wherein the blade 2 and a blade handle 4 are welded together, so that the failure of the screw machine caused by falling off in the using process is avoided; the screw shaft 1 is provided with a mounting hole 6 penetrating through the diameter of the shaft, and the petiole 4 is fixed on the screw shaft 1 through the nut 3 after penetrating through the mounting hole 6; a fastener is arranged between the nut 3 and the main shaft; the fastener includes: the outer tongue locking washer and the elastic washer ensure that the blade handle 4 and the blade 2 can be firmly installed on the screw shaft 1 through the fastener, the angle cannot be changed, the blade cannot be loosened after a long-time use process, and the possibility of the failure of the screw machine caused by the loosening of the blade 2 is reduced.
As shown in fig. 3, the blade 2 has a fan shape; the side wall of the blade 2 is provided with a double-sided chamfer 5; gaps are reserved between the adjacent blades 2; in the conveying process, the smaller interface falls off from the gap between the blades, so that the blades cannot be blocked, and the larger agglomerates can be crushed by the edges and corners of the side walls of the blades and cannot be blocked between the blades; the possibility of failure of the screw machine is reduced.
Each independent blade 2 is arranged on the screw shaft 1 through different inclination angles, and the integral form formed by all the arranged blades 2 is a spiral belt-shaped conveying blade surrounding the screw shaft 1; the petiole 4 is quadrangular; the shape of the inner cavity of the mounting hole 6 is matched with that of the blade handle 4; the petiole 4 and the inner chamber of quadrangular shape also for the cooperation of quadrangular mounting hole 6, ensure that the installation angle of blade 2 can not change in the use, and then ensure that holistic spiral banding conveying blade can not take place to warp in long-term use, ensure that the conveyer can long-term operation.
After the machine is operated, the screw shaft 1 rotates, and materials are conveyed along a spiral belt-shaped conveying blade formed by blades 2 and conveyed from an inlet to an outlet; during operation, because the blades 2 are installed on the screw shaft through the blade handles 4, smaller agglomerates can fall through gaps between the blades 2 and cannot be clamped between the blades 2 and the screw shaft 1; the great material caking can be in the rotary conveying in-process, is hit garrulous by 2 lateral walls of blade, and then drops by the gap between 2 blades, can not cause the screw machine card to hinder yet.
