Description

Technical Field

[0001] The utility model relates to the technical field of solid waste resource utilization, and in particular to a modular on-site crushing system for wind turbine blades. Background Art

[0002] The recycling and disposal of retired wind turbine blades is one of the problems that the wind power industry needs to solve urgently. At present, the technical paths for the recycling and disposal of retired wind turbine blades mainly include physical recycling, disguised life extension, chemical recycling, thermal treatment, etc. However, no matter which technical path is adopted, it is necessary to carry out common pre-treatment work such as cutting and crushing on retired wind turbine blades. Since wind farms are generally located in remote and scattered areas, and wind turbine blades are huge in size, complex in structure, and the main material is high-strength glass fiber-resin composite materials, their transportation costs are high and crushing is difficult. In actual operation, it is found that the material structures of various parts of wind turbine blades are quite different. Parts such as the blade root are pure composite materials and are relatively thick, which makes crushing extremely difficult; the rest of the parts are relatively thin, and parts such as the web are sandwich structures, which make crushing relatively easy. Therefore, how to develop an efficient and energy-saving crushing device and crushing method based on the characteristics of wind turbine blade structural materials has also become one of the problems that the wind turbine blade processing industry needs to solve urgently.

[0003] The Chinese utility model patent with the authorization announcement number CN219377406U discloses a wind turbine blade crushing and sorting line, which includes a shredder, a crusher, a specific gravity sorter, a heavy material vibrating screen and a light material vibrating screen, etc., which can realize the crushing and sorting of wind turbine blade cutting materials. However, this patent is a fixed processing line, and the wind turbine blade cutting materials need to be transported from the wind farm to the processing line. The wind turbine blades are irregular in shape and still have a certain curvature after cutting. The stacking density is low during transportation, and it can only be used in areas with dense wind farms, and the transportation cost is high.

[0004] The Chinese invention patent with the authorization announcement number CN113856876B discloses a mobile industrial solid waste fiber composite material processing system, which integrates crushing, screening and other equipment into a skid and installs it on a car, realizing on-site crushing of waste. However, the patent only includes a primary coarse crushing device, which has poor adaptability to the different thickness characteristics of different structural materials of wind turbine blades and high processing energy consumption.

[0005] The Chinese utility model patent with the authorization announcement number CN219768832U discloses a system for efficiently cutting and crushing large-sized composite solid waste on site. The crushing device is integrated into a vehicle-mounted skid, which can achieve efficient mechanical cutting and crushing of large-sized composite solid waste on site. The crushing device part of the patent also only includes a primary coarse crushing device, which is not very targeted at crushing materials in different structural parts of wind turbine blades.

The energy consumption for processing the cutting materials of a wind turbine blade of this type is approximately: 2 / 0.5*(120+130)+(6-2) / 0.5*130=2040KW·h.

[0101] A whole set of 1.5MW wind turbine blade cuttings was used as the crushing object and processed using a conventional wind turbine blade cuttings crushing processing line. The total mass of the cuttings was about 6 tons, of which the mass of the cuttings with a thickness of more than 40 mm, such as blade roots, was about 2 tons.

[0102] The crushing capacity of the wind turbine blade cutting material crushing processing line is designed based on the root thickness of the wind turbine blade to be processed, and the processing capacity is 0.5t / h. The operating power of the processing line is 240KW, and the energy consumption for processing the cutting material of a wind turbine blade of this model is approximately: 6 / 0.5*240=2880KW·h.
