Description

Technical Field

[0001] This utility model relates to the field of aggregate screening technology, specifically to a screening device for recycled aggregates from decommissioned wind turbine blades. Background Technology

[0002] With the rapid development of the wind power industry, a large number of wind turbine blades will reach the end of their service life and be decommissioned. These decommissioned wind turbine blades are usually made of glass fiber reinforced composite materials or carbon fiber reinforced composite materials, and their recycling is of great significance for environmental protection and resource conservation. The recycled aggregate formed by crushing decommissioned wind turbine blades needs to be screened and graded to obtain products with different particle size ranges to meet the needs of different engineering applications.

[0003] Existing aggregate screening devices, such as vibrating screens, typically include multiple layers of screens to achieve multi-stage screening. After screening, the cleaning and unloading process is also quite cumbersome, especially for multi-layer screens, which require cleaning the aggregates of different particle sizes retained on each layer of screen separately. This results in long operation times, high labor intensity, and low overall work efficiency. Utility Model Content

[0004] In view of the problems existing in the above-mentioned screening device for recycled aggregates from decommissioned wind turbine blades, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a screening device for recycled aggregate from decommissioned wind turbine blades, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A screening device for recycled aggregate from decommissioned wind turbine blades includes a base plate and a vertical plate. The vertical plate is fixedly disposed on one side of the upper surface of the base plate. Multiple through slots are sequentially opened from top to bottom on the vertical plate. A sliding rod is slidably disposed inside the through slot. A movable shell is fixedly disposed at one end of the sliding rod. A screen shell is engaged inside the movable shell. A screen mesh is installed inside the screen shell. A side plate is fixedly disposed on the side of the vertical plate away from the movable shell. Transmission mechanisms for moving the movable shell are disposed on both sides of the side plate. A mounting plate is fixedly disposed on the upper surface of the base plate on the side away from the vertical plate. A limiting mechanism for restricting the longitudinal movement of the screen shell is disposed on the outer wall of the mounting plate.

[0007] Preferably, the transmission mechanism includes a turntable and a pin. A rotating rod is rotatably arranged on the front side of the side plate. The turntable is fixedly sleeved on the rod wall. A pin is eccentrically arranged on the front side of the turntable.

The limiting plate is fixedly disposed at one end of the mounting rod, and the limiting plate abuts against the mounting plate. A fixing tube is fixedly disposed on the side of the limiting plate near the screen shell. A movable rod is slidably sleeved inside the fixing tube. One end of the movable rod is fixedly connected to the screen shell. A mounting block is fixedly disposed on the side of the mounting plate away from the limiting plate. A threaded rod is threadedly sleeved inside the mounting block. An insertion hole is opened on the side wall of the mounting rod near the threaded rod, and one end of the threaded rod is inserted into the insertion hole.

[0009] Preferably, the front end of the round pin is fixedly sleeved with an anti-detachment ring.

[0010] Preferably, the longitudinal section of both the through groove and the slide rod is rectangular, and the wall of the slide rod abuts against the inner wall of the through groove.

[0019] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiment of this utility model. However, this is only for illustrative purposes and is not intended to limit this utility model to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0020] The technical solution of this utility model will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0021] like Figures 1 to 5 As shown, the device includes a base plate 1 and a vertical plate 2. The vertical plate 2 is fixedly disposed on one side of the upper surface of the base plate 1. Multiple through slots are sequentially opened from top to bottom on the vertical plate 2. A slide rod 3 is slidably disposed inside the through slot. A movable shell 4 is fixedly disposed at one end of the slide rod 3. A screen shell 5 is snapped into the movable shell 4. A screen 6 is installed inside the screen shell 5. A side plate 15 is fixedly disposed on the side of the vertical plate 2 away from the movable shell 4. A transmission mechanism for moving the movable shell 4 is disposed on both sides of the side plate 15. An mounting plate 11 is fixedly disposed on the upper surface of the base plate 1 and on the side away from the vertical plate 2. A limiting mechanism for restricting the longitudinal movement of the screen shell 5 is disposed on the outer wall of the mounting plate 11.

[0022] In one possible implementation, the transmission mechanism includes a turntable 9 and a pin 8. A rotating rod 16 is rotatably mounted on the front side of the side plate 15. The turntable 9 is fixedly sleeved on the rod wall of the rotating rod 16. A pin 8 is eccentrically mounted on the front side of the turntable 9. A movable frame 7 is fixedly mounted between the ends of multiple sliding rods 3 away from the movable housing 4. One end of the pin 8 passes through the movable frame 7. A motor 17 is fixedly mounted on the rear side of the side plate 15. The output end of the motor 17 is fixedly connected to one end of the rotating rod 16. Motor 17 drives turntable 9 to rotate, which causes turntable 9 to drive pin 8 to rotate around rotating rod 16, which causes pin 8 to slide in movable frame 7, thus enabling reciprocating push and pull of movable frame 7, thereby causing slide rod 3 to drive movable shell 4 to move, which in turn drives screen shell 5 to move, thus enabling automatic screening of aggregate.

[0023] In one possible implementation, the limiting mechanism includes a limiting plate 12 and a mounting rod 18. The middle side wall of the mounting plate 11 has a mounting hole, and the mounting rod 18 is inserted into the mounting hole. The limiting plate 12 is fixedly disposed at one end of the mounting rod 18, and the limiting plate 12 abuts against the mounting plate 11. A fixing tube 13 is fixedly disposed on the side of the limiting plate 12 near the screen shell 5. A movable rod 14 is slidably sleeved inside the fixing tube 13. One end of the movable rod 14 is fixedly connected to the screen shell 5. A mounting block 19 is fixedly disposed on the side of the mounting plate 11 away from the limiting plate 12. A threaded rod 20 is threadedly sleeved inside the mounting block 19. An insertion hole is opened on the side wall of the mounting rod 18 near the threaded rod 20, and one end of the threaded rod 20 is inserted into the insertion hole. Rotate the threaded rod 20 to separate it from the mounting rod 18, then pull the mounting rod 18 out of the mounting hole. Then move the mounting rod 18 up, and multiple screen shells 5 can be pulled out from their corresponding movable shells 4 at the same time, completing the disassembly of the screen shells 5. This makes it convenient to unload and clean the screen shells 5.

[0024] In one possible implementation, the front end of the circular pin 8 is fixedly sleeved with an anti-detachment ring 10; This effectively prevents the round pin 8 from slipping out of the movable frame 7.

[0025] In one possible implementation, both the through groove and the slide bar 3 have rectangular longitudinal sections, and the wall of the slide bar 3 abuts against the inner wall of the through groove. This prevents the slide bar 3 from rotating relative to the through groove, thus enabling it to slide stably within the through groove.

[0026] In one possible implementation, both the mounting hole and the mounting rod 18 have rectangular longitudinal sections, and the rod wall of the mounting rod 18 abuts against the inner wall of the mounting hole. This prevents the mounting rod 18 from rotating relative to the mounting hole, allowing it to slide stably within the mounting hole.

[0027] In one possible implementation, a knob is fixedly sleeved at the lower end of the threaded rod 20; The threaded rod 20 is easy to rotate.

[0028] In one possible implementation, the motor 17 is fixedly connected to the side plate 15 via a support frame; This makes the connection between the motor 17 and the side plate 15 more secure.

[0029] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the preferred embodiments; however, those skilled in the art can fully understand this utility model without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
