Description

High-strength alloy vertical guard board for sand making machine rotor

Technical Field

The utility model relates to a vertical guard plate for a rotor of a sand making machine, in particular to a high-strength alloy vertical guard plate for the rotor of the sand making machine.

Background

With the increasing investment of highway, railway and other infrastructure in all over the country, large project projects are developed in succession, and a large amount of high-quality gravel aggregate is urgently needed to be supplied. However, in order to protect the ecological environment, the state cannot release the prohibition of natural sand excavation without permission, and the wide market of the machine-made sand is presented. Firstly, the machine-made sand has a larger specific surface area than natural sand, and the concrete prepared from the machine-made sand has higher strength. Secondly, the machine-made sand production can be combined with the production process of the broken stones, so that the production cost of the machine-made sand is greatly reduced. Finally, the machine-made sand is beneficial to the comprehensive utilization of mineral resources, not only solves the environmental problem, but also improves the utilization rate of natural resources. Therefore, sand making machines for making crushed stone into sand are increasingly receiving attention.

The general working principle of the sand making machine is as follows:

the stones fall into the rotating disc rotating at high speed from the upper part of the impact type sand making machine, and under the action of high-speed centrifugal force, the stones and the other parts of the stones are distributed around the rotating disc in an umbrella shape to generate high-speed impact and high-density crushing. After the stones impact each other, a vortex motion is formed between the rotary disc and the shell, so that multiple times of impact, friction and crushing are caused, and even the stones are crushed to the required granularity.

In the operation process, a large amount of ores fall into the upper material throwing plate in the upper crushing cavity from the feed hopper, materials are thrown to the inner wall of the cylinder by the centrifugal force of the material throwing plate and violently collide with the reverse plate arranged on the inner wall, and meanwhile, the materials collide with each other to be crushed or generate a large amount of fine cracks. After the materials enter the conical rotor cavity, the materials spirally fall in the conical space, and the crushed ores are further crushed through punching and extrusion. The inclination between the conical rotor and the lining plate forces smaller materials to move downwards, thereby realizing automatic grading crushing from large to small. The material enters the center of the rotor from a central feeding pipe of a distributor on the upper part of the impeller, the material is uniformly distributed to each launching runner of the impeller by a material distribution cone in the center of the rotor, and a wear-resistant block made of special materials is arranged at the outlet of each launching runner and can be replaced. The rotor accelerates the material to a certain speed to be thrown out, the material impacts a material lining layer in the whirling crushing cavity to carry out strong self-crushing, and an upper flow channel plate and a lower flow channel plate are arranged between a conical cap and a wear-resistant block of the rotor, so that the rotor is protected from being worn. The material is beaten by the tup at rotor intracavity, and high-speed cubic material collides with the board once more, and the material flows collision each other, and the material is beaten, is cuted, is extruded crushing, improves crushing efficiency. The material falling from the conical rotor cavity enters the lower crushing cavity, and is further crushed into small particles through the centrifugal force of the material throwing plate. The material finally enters the cylindrical rotor chamber and the ground material is ground, causing the material to be further finely ground until the desired particle size is achieved.

The grit that the material collided the back each other and produced flows by the feed opening after dividing the material through the inside perpendicular backplate direction of rotor, and it has the grit collision constantly to found the backplate, leads to founding that the backplate wearing and tearing are serious, if not change in time can lead to the impeller inner chamber impaired.

As shown in fig. 1 and 2, a conventional vertical guard plate comprises a vertical guard plate body 1, wherein a mounting hole 2 for mounting the vertical guard plate is formed in the vertical guard plate body 1, and one side surface of the vertical guard plate body 1 is an inclined surface, i.e. a surface colliding with sand; the vertical protection plate body 1 is cast by a high-chromium-content wear-resistant material, so that the service life is short, the replacement is frequent in the working period, and the working efficiency of the rotor is reduced.
