[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] The fan blade fragments are pulverized by a geared motor-driven pulverizing roller. The pulverized fragments fall into a chamber where a mixing and heating assembly further decomposes them. Figure 1-3 As shown, the present invention provides a wind turbine blade fragment processing device, comprising a housing 1, a heating component 4 disposed inside the housing 1, a stirring component 3 disposed inside the heating component 4, a housing cover 2 fixed to the top of the housing 1 by bolts, a guide block 5 fixed inside the housing cover 2 by bolts, a crushing roller 6 rotatably connected to the inner ends of the housing cover 2 at the bottom of the guide block 5 by bearings, and a reduction motor 10 mounted on one end of the housing cover 2 by a mounting bracket, the output shaft of the reduction motor 10 being fixedly connected to one end of the crushing roller 6 by a connecting sleeve; The heating assembly 4 includes a stainless steel plate 401 fixed to the inside of the housing 1 by bolts. Electric heating wires 402 are equidistantly arranged inside the stainless steel plate 401 by bolts. The stirring assembly 3 includes a shaft 301 rotatably connected to the inside of the stainless steel plate 401 by bearings. Stirring rods 302 are equidistantly welded to the outside of the shaft 301. A drive motor 303 is mounted on one end of the housing 1 by a mounting bracket.

[0017] During use, the geared motor 10 drives the crushing roller 6 to rotate, further crushing the fan blade fragments inside the housing 2. The electric heating wire 402 heats the ethylene glycol / sodium hydroxide mixed solvent and the fan blade fragments inside the housing 1. The shaft 301 and the stirring rod 302 on its outer side rotate to stir the ethylene glycol / sodium hydroxide mixed solvent and the fan blade fragments.

[0018] For example, such as Figure 2 As shown, the present invention also includes a drive motor 303 with one output shaft fixedly connected to one end of shaft 301 via a connecting sleeve, and the stainless steel plate 401 located inside the electric heating wire 402 is filled with magnesium oxide powder 403 on its outer side.

[0019] In use, the drive motor 303 drives the shaft 301 to rotate, and the magnesium oxide powder 403 serves as insulation and heat conduction.

[0020] For example, such as Figure 3 As shown, the present invention also includes a plate sleeve 7 welded to one side of the box cover 2, a baffle 8 being sleeved through the inside of the plate sleeve 7, and a structural groove 9 for easy insertion of the baffle 8 being opened on the inner side of the box cover 2 at the bottom of the guide block 5.

[0021] When in use, the inner baffle 8 of the plate sleeve 7 is inserted into the box cover 2 to collect the crushed fan blade fragments and to block the gap between the box body 1 and the box cover 2, reducing the loss of heat inside the box body 1.

[0022] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a thermostat 13 mounted on one end of the housing 1 via a mounting base. The detection end of the thermostat 13 is located inside the housing 1, and the current output end of the thermostat 13 is electrically connected to the current input end of the heating wire 402 via a power cord.

[0023] During use, the heating of the electric heating wire 402 and its heating temperature can be controlled by the thermostat 13.

[0024] For example, such as Figure 1 As shown, the present invention also includes a box cover 2 connected to a box body 1, a hopper 12 welded to the top of the box cover 2, and a tempered glass window 11 fixed to one side of the box cover 2 by bolts.

[0025] In use, the hopper 12 is designed to allow personnel to pour the broken fan blades into the housing 2, and the tempered glass window 11 is designed to allow personnel to observe the broken fan blades on the baffle 8.

[0026] For example, such as Figure 1 As shown, the present invention also includes a door 14 hinged to one side of the box body 1, and a feeding port 15 opened on the top of the box body 1 located on one side of the box cover 2.

[0027] When in use, the material inside the box 1 can be taken out by opening the box door 14, and it is convenient to repair and replace the stirring component 3 and heating component 4 inside the box 1. The feeding port 15 is set to facilitate the addition of auxiliary materials and agents such as ethylene glycol / sodium hydroxide mixed solvent into the box 1.

[0028] When using this utility model, the operator connects the device to an external power source using a power cord, pours the fan blade fragments into the hopper 12, and the fan blade fragments entering the hopper 12 fall into the housing 2. The fan blade fragments entering the housing 2 are guided by the guide block 5 and fall between the two crushing rollers 6. The reduction motor 10 is turned on to drive the crushing rollers 6 to rotate, crushing the fan blade fragments and further breaking them down. The baffle 8 inside the sleeve 7 is inserted into the structural groove 9 inside the box cover 2 to block the crushed fan blade fragments inside the box cover 2. Personnel can observe the fan blade fragments on the baffle 8 through the tempered glass window 11. Pull one end of the baffle 8 out of the box cover 2 so that the fan blade fragments can fall into the box body 1. Ethylene glycol / sodium hydroxide mixed solvent is poured into the chamber 1 in proportion through the feed port 15. The electric heating wire 402 is controlled by the temperature controller 13. The magnesium oxide powder 403 absorbs the heat generated by the electric heating wire 402 and conducts it to the stainless steel plate 401 to heat the fan blade fragments and ethylene glycol / sodium hydroxide mixed solvent in the chamber 1, promotes the decomposition of the fan blade fragments, and can decompose the epoxy resin. The drive motor 303 drives the shaft 301 and the stirring rod 302 on its outer side to rotate at high speed, mixing the ethylene glycol / sodium hydroxide mixed solvent and the fan blade fragments in the box 1, thereby improving the reaction and decomposition efficiency of the ethylene glycol / sodium hydroxide mixed solvent and the fan blade fragments.
