[0002] Since 2008, the installed capacity of wind power generation has increased year by year, wind power blades are made of glass steel composite materials, and wind power generation has the advantages of being clean, renewable, having a short construction period, and flexible installation scale;

[0003] However, the design service life of the wind power blade is 20 years, the size is too large, and the surrounding infrastructure is easily damaged during the process of being disassembled from the installation site and transported to the processing plant, the traditional processing method mainly burns and pollutes the environment, causing secondary pollution of the vegetation and water source near the land, but the material can be recycled and reused, which is of great significance; SUMMARY

[0007] Further, the reaction container is composed of six cylindrical sections with different lengths, i.e. the circular closing end, the circular transition section, the profiled cross-section curve connecting section, the profiled cross-section curve maximum section, the closing transition end and the connecting closing end, so that the reaction container can accommodate the blade body, and the profiled cross-section curve maximum section can complete the arrangement and storage tasks of other sections, meeting the volume requirement and transportation requirement;

[0008] The upper surface of the reaction base is provided with an internally concave arc structure, and the inside right-angle part of the reaction base is additionally provided with a reinforcing rib;

[0028] The following will be combined with the appendix Figures 1-8 The technical solutions in the embodiments are described clearly and completely.

[0029] Specific implementation method one: as follows Figures 1-3As shown, the integral blade-shaped reaction vessel consists of 6 cylindrical sections of different lengths, from left to right: circular constriction end 1, circular transition section 2, contoured cross-section curve connecting section 3, contoured cross-section curve maximum section 4, constriction transition end 5, and connecting constriction end 6. The blade body 12 is inserted inside the integral reaction vessel. To ensure the fit between the integral reaction vessel and the blade body 12, the cross-section of each cylindrical connecting structure is designed with a blade-shaped profile. This makes the fit between the integral reaction vessel and the blade body 12 more accurate and the manufacturing process better. By reducing the size and expanding the shape, the limits are avoided, and the gap between the inner wall of the cylinder and the blade body 12 is more uniform, which greatly saves the use of reaction solution and improves the economy and practicality of the device. The central axes of circular constriction end 1, circular transition section 2, contoured cross-section curve connecting section 3, contoured cross-section curve maximum section 4, constriction transition end 5, and connecting constriction end 6 are not the same axis.

[0030] The size of the opening at one end of the circular tapered end 1 can be changed according to the size of the pressurizing equipment for smoother assembly; the circular transition section 2 and the contoured section curve connecting section 3 are coaxial and used to connect the maximum section 4 of the contoured section curve to meet the length requirements; the maximum section 4 of the contoured section curve completes the sorting and storage of other sections to meet the volume and transportation requirements.

[0031] There are four reaction bases 7, which support the four larger diameter and volume sections of the container. The four larger diameter and volume sections are the circular constriction end 1, the circular transition section 2, the contoured cross-section curve connecting section 3, and the largest contoured cross-section curve section 4. The upper surface of the reaction base 7 is a concave arc structure. The right-angled part of the inner side of the reaction base 7 is reinforced with ribs. The structure of the reaction base 7 includes a contact support part that is completely consistent with the outer surface of the container, and reinforcing ribs added to the right-angled part to enhance the support strength. The reaction base 7 is mainly used when the container unfolds for reaction.

[0032] Specific implementation method two: such as Figures 4-8 As shown, the transport base 8 consists of two parts, which are assembled by two identical semi-contour curved bases. Bolts are used to connect and fix the transport base, which plays a role in protecting the container. Its length and width can ensure that the reaction container meets the transport requirements during transportation.

[0033] like Figure 5As shown, when installing each cylindrical section, firstly, remove both ends of the circular constriction end 1 to place the blade body 12 into the reserved space. Then, pull out the cylinders in the largest section 4 of the contoured cross-section curve in descending order of size. When the cylinder is pulled out to the point of encountering great resistance, observe closely for any obvious gaps. If there are no abnormalities, use the sealing bolts. All connecting parts of each cylindrical structure are sealed with sealing gaskets 9 and bolts. This allows the shrink container to fit all sections into the largest section 4 of the contoured cross-section curve, greatly reducing the transportation volume. At the same time, it also provides tolerance for the previous steps. After this step is completed, the blade body 12 can be placed in the container. Then, simply connect the smaller cylinders at both ends of the circular constriction end 1 with bolts, and finally connect the opening to the pressurization equipment.

[0034] like Figure 6 As shown, the reaction solution is pumped by a liquid injection pump 10 fixedly installed at one end of the constriction end 6, so that the reaction solution can be quickly injected into the reaction container. Then, the reaction solution is heated and stirred by heating rods 11 installed between the circular constriction end 1, the circular transition section 2, the contoured cross-section curve connecting section 3, the maximum section of the contoured cross-section curve 4, the constriction transition end 5 and the sealing gasket 9, so that the blade body 12 and the reaction solution can react fully. After the reaction is completed, the reaction solution is pumped out by the liquid injection pump 10 for effective recovery.

[0035] Based on the material and aging degree of the blades to be recycled, intelligent equipment can be used to adjust the dissolution process parameters, control the temperature, pressure, stirring and circulation, thereby accelerating the reaction efficiency of the solution and the blade body 12 and the recovery efficiency of effective components, which is conducive to improving the utilization rate of materials.

[0036] Due to the cross-sectional structure of the curved connecting section 3 and the maximum section 4 of the curved section, the container with the curved section structure has better stability than the circular container, which has outstanding advantages in transportation and reaction. The container with the curved section is not easy to move around, which can effectively save the amount of reaction solution used, and makes it easier to inject, drain and recycle the reaction solution.

[0037] When collecting the solution after the reaction of the blade body 12, the liquid in the reaction vessel can be completely discharged by the injection pump 10. The discharged solution can be recycled. The recycled solution can provide raw materials for reinforcing glass, carbon fiber cloth, etc., thereby improving the flexibility of the recycling process and the economic benefits of the device. The pressurization equipment is removed. The disassembly steps are the reverse of the installation steps. The cylinder is completely inserted into the maximum section 4 of the contoured cross-section curve and then inserted into the transport base 8 to prevent the cylinder from moving.

[0038] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with preferred embodiments as above, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical contents without departing from the technical solution of the present application, and can make equivalent embodiments with equivalent changes, as long as they do not depart from the technical solution of the present application and are within the spirit and principle of the present application.
