Problems solved by technology

However, the FRP powder material crushed by this process is the same as the FRP powder material crushed by the traditional process. The powder glass fiber is thicker and longer, so that its recycling is limited accordingly.

Embodiment 1

[0073] Embodiment 1 (laboratory model)

[0074] The cutting knife adopts diamond corrugated slices and diamond thickened slotted slices to be superimposed and combined. The slice gap is separated by a 4mm barrier gasket. The slice knife edge (referring to the gap between the outer edges of two adjacent slices) is 0.5mm--1mm , using 5+4 nine slices to form a cutting mechanism with an arrangement width of about 70mm.

[0075] The nine slices correspond to A-D-A-D-A-D-A-D-A in Table 1 in turn.

[0076] When in use, the pre-cut material is decomposed into blocks or strips with a cross-sectional width of less than 70mm*60mm, and then cut. After cutting, it is sieved with 120 meshes, and the mesh passing rate is >85%. See the particle size distribution after passing through the screen figure 2 , the cutting efficiency is shown in Table 2.

Embodiment 2

[0077] Embodiment 2 (industrial minicomputer)

[0078] The cutting knife is superimposed and combined with diamond corrugated slices and diamond thickened slotted slices. The slice gap is isolated by a 6mm barrier gasket. The gap between the slice blades is 0.5mm--1mm. 5+4 nine slices are composed of an arrangement width of about 100mm. cutting mechanism.

[0079] The nine slices correspond to B-E-B-E-B-E-B-E-B in Table 1 in turn.

[0080] When used, the pre-cut material is decomposed into block or strip materials with a cross-sectional width less than 100mm*60mm, and then cut. The particle size distribution after cutting is shown in image 3 , the cutting efficiency is shown in Table 2.

Embodiment 3

[0081] Embodiment 3 (industrial mainframe)

[0082] The cutting knife adopts V-diameter diamond grooved slices and diamond thickened grooved slices to be superimposed and combined. The slice gap is separated by a 6mm barrier gasket. The gap between the slice blades is 1mm--2mm, and the arrangement width of 5+4 nine slices is 150mm. Left and right cutting mechanism.

[0083] The nine slices correspond to C-F-C-F-C-F-C-F-C in Table 1 in turn.

[0084] When using, decompose the pre-cut material into block or strip materials with a cross-sectional width less than 150mm*60mm, and then cut them. See the particle size distribution after cutting. Figure 4 , the cutting efficiency is shown in Table 2.

[0085] Performance Characterization

[0086] The pulverization efficiency is the output of the powder obtained from the continuous production of the pulverization equipment of the corresponding model of the present invention for 1 hour, and is marked in kilograms per hour; the parti...

Abstract

The invention discloses mashing equipment for smashing of a glass fiber composite material or a rubber material. The equipment comprises a box body; a feeding cavity, a smashing cavity and a discharging cavity are sequentially arranged in the box body in the material conveying direction; a cutter is rotationally connected in the smashing cavity; a conveying belt for conveying materials is disposed in the feeding cavity; the output end of the conveying belt transits to the outer edge of the cutter through a joining plate; a material pressing wheel located above the conveying belt is disposed in the feeding cavity in a sliding mode through an elastic support; a material channel which joins the feeding cavity with the smashing cavity is disposed between the conveying belt and the material pressing wheel. A high-speed motor drives a smashing and cutting mechanism formed by combination of diamond cutting blades to smash strip-shaped and small blocky glass fiber composite material or rubber material at a time, and smashing particle diameter d50 of powder can be controlled to be about 20-30 micrometers. The technical difficulty of finely smashing of recycled materials in the industry is solved, and favorable conditions are created for recycling of the glass fiber composite material and part of the rubber material.

Description

technical field [0001] The invention relates to the field of processing equipment and the field of environmental protection, in particular to a crushing device for crushing glass fiber reinforced plastic composite materials or rubber materials. Background technique [0002] FRP composite material is a kind of plastic reinforced by reinforcing materials such as glass fiber or carbon fiber. Because of its high strength, good toughness, corrosion resistance and compression resistance, it is widely used in industrial and civil occasions, and can even be used as a high-pressure gas cylinder and other pressure container. Generally, the indoor design life of FRP materials is 20-30 years, while the outdoor design life is only 10-20 years, and the actual use is even less than the design life. FRP has been used in my country for more than 50 years. The utilization and disposal of a large number of decommissioned FRP materials and redundant FRP production materials will be a major iss...
