Problems solved by technology

Large pieces of FRP waste such as wind turbine blades can be cut into a size of 500mm-1000mm by diamond wire cutting, and then cut into 80mm-250mm by a single-shaft crusher, and then crushed to a smaller particle size However, there is a lack of effective crushing equipment. This is mainly because the FRP material not only has high hardness, but also although it is relatively brittle, the reinforcing fiber material contained in it will make the crushed materials stick together or stick to the crushing mechanism, which will hinder the crushing process. The smooth progress of the crushing process, due to the characteristics of the FRP material, it is better to use the blow method to crush it.

Embodiment 1

[0016] Embodiment 1: The main shaft 5 is vertically installed in the center of the crusher through the bearing 4, the chain 8 and the cutter head hammer assembly 7 are fixed on the same main shaft 5, the motor 1 drives the main shaft 5 to rotate through the transmission mechanism 2, and then drives the chain 8 And the movement of the cutter head hammer head assembly 7 strikes and breaks the material. The motor speed and main shaft speed can be adjusted according to the needs, and since the same rotating shaft is shared, the two-stage crushing process will be carried out at the same time.

[0017] The material to be crushed enters the upper crushing cavity from the top, and after being crushed by the rotating chain, it enters the lower cavity 6 through the lower trough 9. The opening size of the lower trough 9 can be adjusted to control the output of the material and the output.

[0018] Inside the lower cavity 6 are multi-layer crushing cutterheads 10, the diameter of each lay...

Abstract

The invention relates to a composite glass fiber reinforced plastic crusher which is composed of an upper-layer crushing mechanism and a lower-layer crushing mechanism, wherein the two crushing mechanisms share a rotating main shaft and are vertically integrated, materials crushed by the upper-layer mechanism directly enter a lower-layer crushing part to continue to be crushed. The upper-layer crushing of the composite crusher adopts a free single-chain crushing way, a single chain is fixed on a main shaft in an upper-layer crushing cavity, and the other end of the chain is freely arranged. The chain is driven through high-speed rotation of the main shaft to beat and crush the materials entering the rotation range. The lower-layer crushing of the composite crusher adopts a crushing way that hammer heads are fixed in a conical cavity. A plurality of layers of cutter heads are distributed on the main shaft in the conical crushing cavity from top to bottom in a tower shape, and a plurality of hammer heads are fixedly connected to each layer of cutter head. The materials discharged from the upper-layer crushing part enter the cavity from the upper part to be beat by the hammer heads on the high-speed rotating cutter heads or extruded and ground by the hammer heads and a cavity wall so as to be crushed.

Description

technical field [0001] The invention belongs to the technical field of crushing machinery, and in particular relates to a multi-composite glass fiber reinforced plastic crusher. Background technique [0002] With the rapid increase in the production and use of FRP in my country year by year, the waste of FRP is increasing. Due to the excellent corrosion resistance of FRP, it is difficult to destroy it naturally. The threat of FRP waste to the environment is increasing, and the demand for the disposal of these wastes is becoming more and more urgent. At present, the more economical and environmentally friendly treatment method is to treat them Recycling after physical pulverization or chemical pyrolysis is used as filler for reuse. Both methods require crushing of waste with different particle sizes. Large pieces of FRP waste such as wind turbine blades can be cut into a size of 500mm-1000mm by diamond wire cutting, and then cut into 80mm-250mm by a single-shaft crusher, and...
