Description

Technical Field

[0001] This utility model relates to the field of hot pressing molding technology, specifically a hot pressing molding device for prefabricated solid waste components for wind turbine blades. Background Technology

[0002] Wind power, as a clean and renewable energy source, has developed rapidly worldwide in recent years. With the expansion of the wind power industry, the production and use of wind turbine blades are also constantly increasing. However, wind turbine blades are usually replaced after a certain period of use due to aging, damage, and other reasons, generating a large amount of solid waste. This waste mainly includes glass fiber reinforced plastics (GRP) and other composite materials, making the treatment of wind turbine blade solid waste a new environmental challenge. Traditional treatment methods such as landfill and incineration not only waste resources but may also cause secondary pollution.

[0003] Currently, some technologies have attempted to recycle wind turbine blades, such as converting them into smaller particles or powdered solid waste through mechanical crushing and pyrolysis. In the reuse of wind turbine blade solid waste, hot pressing of preforms is a crucial step. Hot pressing is a method of reshaping solid waste under high temperature and pressure to produce preforms with specific shapes and sizes. However, existing hot pressing equipment for processing wind turbine blade solid waste typically works in conjunction with conveying equipment. When the conveying equipment transports the molding die to near the injection or hot pressing position, it usually needs to pause and wait, incurring significant waiting time and reducing equipment efficiency. Therefore, we propose a hot pressing device for preforms made from wind turbine blade solid waste. Utility Model Content

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0025] Example 1

[0026] Please see Figures 1-5 As shown, this utility model provides a technical solution: a hot pressing molding device for prefabricated solid waste components for wind turbine blades, comprising:

[0027] Box 1, guide grooves 101 are provided on both sides of box 1, first electric push rods 104 are fixedly installed on both sides of the left end of box 1, and connectors 102 that slide in the guide grooves 101 are fixedly installed on the extended ends of the first electric push rods 104. Second electric push rods 105 are fixedly installed on the top and bottom of the right end of box 1, and pressure plates 103 are fixedly connected to the extended ends of the second electric push rods 105. Guide plates 106 are fixedly connected to the lower end of the inner wall of box 1.

[0028] A movable plate 3 has a guide pin 301 movably connected to one side of the movable plate 3 via a bearing. A rotating arm 302 is fixedly connected to the outer surface of the guide pin 301. A roller 303 is movably connected to one end of the rotating arm 302 via a bearing. A limiting plate 304 is fixedly connected to the top of the rotating arm 302. An arc-shaped rod 305 that slides on the inner surface of the movable plate 3 is fixedly connected to the bottom of one end of the limiting plate 304. A limiting block 307 is fixedly connected to one side of the arc-shaped rod 305. A spring 306 sleeved on the outside of the arc-shaped rod 305 is fixedly connected between the limiting block 307 and the bottom of the movable plate 3.

[0029] The precast mold frame 5 slides on the top of the guide plate 106, and a sealing plate 501 is placed at the lower end of the inner side of the precast mold frame 5.

[0030] The movable plate 3 is located inside the box 1, and the movable plate 3 is fixedly connected to one side of the connector 102. The arc rod 305 is centered on the axis of the guide pin 301. The left end of the guide plate 106 is an arc structure that flips downward. Conveyor seats 4 are fixedly installed on both the left and right sides of the box 1.

[0031] This technical solution: Before starting the operation of this device, the equipment needs to be inspected. Once the equipment is in normal working order, mains power is connected to the device via the main control switch. Then, the control panel 204 sets the device's normal operating procedure based on existing technology. After the device is turned on, the left-side conveyor seat 4 of the housing 1 can convey the precast mold frame 5 towards the housing 1. When the precast mold frame 5 contacts the leftmost roller 303 of the moving plate 3 (from... Figure 3 and Figure 4As can be seen from the above, there are three sets of rollers 303, which correspond to the material handling, material injection, and hot pressing positions from left to right. With the assistance of the limiting plate 304, when the conveying force is continuous, the rollers 303 can drive the rotating arm 302 to rotate upward around the guide pin 301, and the arc rod 305 is centered on the axis of the guide pin 301. Therefore, when the rotating arm 302 rotates, it can drive the arc rod 305 and the limiting block 307 to rotate through the limiting plate 304. With the cooperation of the moving plate 3 which remains in a fixed position, the spring 306 fixedly connected to its bottom will be compressed, and the rollers 303 will move against the upper surface of the preform mold frame 5. When the rollers 303 pass the preform mold frame 5, the compressed spring 306 will drive the rotating arm 302 to return to its original position in the opposite direction around the guide pin 301 through the limiting block 307, the arc rod 305, and the limiting plate 304 (as shown). Figure 1 and Figure 2 (as shown), thereby enabling the material to be taken from the precast mold frame 5;

[0032] When the first electric push rod 104 drives the connecting piece 102 to slide outward within the guide groove 101, it can drive the moving plate 3 to move smoothly to the right. As the moving plate 3 moves, it will move the corresponding preform mold frame 5 onto the guide carrier plate 106 via the leftmost roller 303, and then drive the corresponding preform mold frame 5 to slide onto the guide carrier plate 106 to the injection position (i.e.,...). Figure 2 (Directly below the top hole of the middle box 1), while the roller 303 in the middle of the moving plate 3 will drive the preform mold frame 5 after injection to the corresponding position of the pressure plate 103. At the same time, the roller 303 at the right end of the moving plate 3 will drive the preform mold frame 5 after hot pressing to the conveyor seat 4 on the right side of the box 1. The conveyor seat 4 can transfer it downwards. When the first electric push rod 104 drives the connecting piece 102 to slide inward in the guide groove 101, it can drive the moving plate 3 to move smoothly to the left. The rollers 303 in the middle and right ends of the moving plate 3 will move again to the injection. On the left side of the preform mold frame 5 at the injection position and the hot pressing position (the principle is as described above), at the same time, the roller 303 at the leftmost end of the moving plate 3 continues to collect the preform mold frame 5 transmitted from the left side conveyor seat 4 of the box 1. During this period, the preform mold frame 5 at the injection position begins to inject material. At the same time, the second electric push rod 105 drives the pressure plate 103 to extend, thereby enabling the material inside the preform mold frame 5 at the hot pressing position to be hot-pressed (the setting of the sealing plate 501 can seal the bottom of the inner side of the preform mold frame 5, and at the same time, it can cooperate with the pressure plate 103 located below the sealing plate 501 to hot-press the material).

[0033] After hot pressing is completed, the second electric push rod 105 drives the pressure plate 103 to retract and return to its original position. At the same time, the material injection and material removal are completed, and the first electric push rod 104 works again. This cycle can avoid the situation where the conveyor seat 4 stops and waits. It can also complete the position changes of the preform mold frame 5 of the material removal position, the material injection position, and the hot pressing position in one go, which can improve the working efficiency of the device and make it easy to use.

[0034] It should be noted that the precast component mold frame 5 is frame-shaped mainly for block precast components, which can be widely used in construction. At the same time, the first electric push rod 104, the second electric push rod 105, the closed hot pressing common state chamber 2, the automatic control hopper 201, the metering hopper 202, the bracket 203, the control panel 204, the conveyor seat 4, the precast component mold frame 5, and the sealing plate 501 used in this device can all be purchased directly from the market. In addition, the connection method and electrical connection relationship of each component adopt mature conventional methods in the existing technology, so they will not be described in detail here.

[0035] Example 2

[0036] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, a closed hot-pressing co-conditioning chamber 2 is provided on the top of the housing 1, a metering chamber 202 is provided at the bottom of the closed hot-pressing co-conditioning chamber 2, an automatic control hopper 201 is provided on the top of the closed hot-pressing co-conditioning chamber 2, a bracket 203 is fixedly installed at the lower end of the closed hot-pressing co-conditioning chamber 2, and a control panel 204 is fixedly installed on the front of the bracket 203.

[0037] This technical solution: By setting up a closed hot-pressing common-state chamber 2, it can receive mixed materials from the weighing hopper. Through the closed environment and hot-pressing process, the materials are prevented from being contaminated by the outside world, and the leakage of volatiles during the hot-pressing process is also prevented. Through heating and pressurization, the solid waste materials and auxiliary and external materials undergo physical and chemical changes (such as resin melting and bonding, fiber recombination), realizing the recycling of waste materials. Through the setting of the automatic control hopper 201, it is divided into a waste hopper for storing recycled solid waste materials (such as scrap materials and scrapped parts from wind turbine blade production), an auxiliary hopper for storing auxiliary materials (such as resin and additives), an external material hopper for supplementing special raw materials (such as reinforcing fibers and modifiers to optimize the performance of materials after hot pressing), and a weighing hopper for accurately controlling the discharge ratio of the three sub-hoppers through weighing (to ensure the consistency of material formula), and then uniformly transporting them to the next stage. Through the setting of the metering hopper 202, the injected materials are accurately metered to ensure the accuracy of discharge (the above are all mature existing technologies, so they will not be described in detail here).

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
