An automatically sorted construction waste recycling device

Abstract

This invention discloses an automatic sorting and recycling device for construction waste, relating to the field of construction waste recycling technology. It includes a first mounting frame and a second mounting frame. A magnetic separation mechanism is mounted on the first mounting frame, and an inclined platform is mounted on the second mounting frame. The magnetic separation mechanism is located above the inclined platform. This invention uses a magnetic separation mechanism to attract magnetic impurities onto the surface of an annular elastic sleeve. As the structure rotates, the magnetic impurities are transported upwards. During this process, the strip-shaped slide gradually moves closer to the center of rotation. At this time, the portion of the annular elastic sleeve above the curved guide section deforms due to gravity and the pressure of the impurities. Supported by the inclined support plate, the annular elastic sleeve tilts to one side while concave. Because the distance between the strip-shaped slide and the magnetic impurities increases, the magnetic attraction force decreases significantly, and the magnetic impurities slide away from one side along the tilted annular elastic sleeve. Based on the rotation of the structure, a series of operations—attracting, lifting, and outputting magnetic impurities—are achieved.

Description

Technical Field

[0001] This invention relates to the field of construction waste recycling technology, and in particular to an automatic sorting construction waste recycling device. Background Technology

[0002] In the process of rapid urbanization, the construction industry is booming, and the amount of construction waste generated is also increasing dramatically. This construction waste is complex in composition, containing a large amount of metallic materials (such as magnetic impurities like iron nails and steel rebar fragments), concrete blocks, bricks, and other non-metallic waste. Traditional construction waste disposal methods are relatively crude, often involving simple landfilling or dumping, which not only occupies a large amount of land resources but also causes serious environmental pollution to soil, water, and air.

[0003] With increasing environmental awareness, the requirements for the recycling and processing of construction waste are also gradually increasing. How to efficiently and accurately sort out magnetic impurities with reuse value has become an urgent problem to be solved. While some existing construction waste recycling devices have certain sorting functions, they still have many shortcomings in practical applications.

[0004] Some devices employ a simple magnetic separation principle, but their unreasonable structural design results in poor magnetic adsorption. For example, the fixed position of the magnetic components prevents dynamic adjustment based on the material's movement, making it difficult to effectively adsorb smaller magnetic impurities and leading to low sorting efficiency. Furthermore, after adsorption, the lack of a proper conveying and release mechanism causes magnetic impurities to accumulate inside the equipment, affecting subsequent sorting operations.

[0005] A search revealed Chinese patent application CN202010805797.8, which discloses a recycling device for sorting construction waste. The device includes a machine body and an upward-opening compression chamber within the machine body. The compression chamber contains a compression device that can compress and lightly crush the placed construction waste. The recycling device in the aforementioned document has the following shortcomings: although it also uses electromagnets for magnetic separation, the overall processing efficiency is low. Furthermore, the process of conveying and magnetic separation requires numerous power sources and drive motors, resulting in high costs and difficulty in maintenance. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic sorting and recycling device for construction waste.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An automatic sorting construction waste recycling device includes a first mounting frame and a second mounting frame. A magnetic separation mechanism is mounted on the first mounting frame, and an inclined platform is mounted on the second mounting frame. The magnetic separation mechanism is located above the inclined platform. The magnetic separation mechanism includes: A ring frame, with a rotating frame installed on one side of the ring frame.

A rotation drive unit is mounted on the first mounting bracket and is used to drive the rotation bracket to rotate. The support cylinder is fixed to the other end of the first mounting frame by a bracket. An annular elastic sleeve is fixed on the side of the annular frame away from the rotating frame. The annular elastic sleeve is located on the outside of the support cylinder. Based on the rotation of the annular frame, the annular elastic sleeve rotates on the outer wall of the support cylinder. The slide guide rod is fixed inside the ring frame. Multiple slide guide rods are arranged in a circular pattern. A slide seat is slidably connected to the outer wall of the slide guide rod. The slide seat and the end of the slide guide rod are connected by a slide spring. A strip slide is installed on one side of the slide seat. An electromagnet is installed inside the strip slide. The support cylinder includes an arc-shaped part and a curved guide part. The center of the arc-shaped part is adapted to the rotation center of the ring frame. The curved guide part is integrally set on the top of the arc-shaped part. The two ends of the curved guide part are smoothly transitioned to the arc-shaped part. The middle part of the curved guide part is recessed towards the center of the arc-shaped part to form an M-shaped structure. An inclined support plate is fixed on the curved guide part of the support cylinder. The inclined support plate is located in the recess of the curved guide part. The height of the inclined support plate gradually decreases in the direction away from the ring frame. The strip slide is pressed against and slides against the inner wall of the support cylinder under the action of the slide spring.

[0008] As a preferred embodiment of the present invention: the rotation drive unit includes a sorting drive motor, which is mounted on a first mounting frame via a motor mount. The output end of the sorting drive motor is connected to a drive gear, and a driven gear is mounted on the shaft of the rotating frame. The driven gear meshes with the drive gear.

[0009] As a preferred embodiment of the present invention, a guide plate is connected to one side of the outer wall of the top of the support cylinder, and the cross-sectional shape of the guide plate is adapted to the shape of the curved guide portion of the support cylinder.

[0010] As a preferred embodiment of the present invention: a guide slide rod is fixed to the outer wall of the bottom of the inclined platform, the guide slide rod is slidably connected to the inner wall of the second mounting frame, the guide slide rod and the second mounting frame are connected by a vibration auxiliary spring, and an auxiliary actuation mechanism for promoting the vibration of the inclined platform is installed on the second mounting frame.

[0011] As a preferred embodiment of the present invention: the auxiliary actuation mechanism includes a cam motor, which is mounted on the outer wall of one side of the second mounting bracket. The output end of the cam motor is connected to a cam, and an end frame is fixed at the bottom of the inclined platform. The end frame is located on the movement path of the cam.

[0012] As a preferred embodiment of the present invention, the inclined platform is provided with ribs that are evenly distributed.

[0013] As a preferred embodiment of the present invention, inclined baffles are provided on both sides of the inclined platform, and the two inclined baffles are in an inverted octagonal structure.

[0014] As a preferred embodiment of the present invention: a transverse actuation mechanism is installed on the inclined platform, the transverse actuation mechanism includes multiple connecting frames, multiple levers are rotatably installed on the connecting frames, transverse slides are fixed at both ends of the connecting frames, the transverse slides slide laterally on the inner wall of the inclined baffle, and the transverse slides and the inclined baffle are connected by a return spring; a corrugated plate is installed on the top of one transverse slide, and multiple ball joints are installed on one side of the rotating frame, with the corrugated plate located on the movement path of the ball joints.

[0015] As a preferred embodiment of the present invention, the inclined platform is provided with uniformly distributed sieve holes, and a receiving and conveying mechanism is provided at one end of the inclined platform and below the sieve holes.

[0016] As a preferred embodiment of the present invention: the receiving and conveying mechanism includes a conveyor belt mounting frame, on which two conveyor belt assemblies are mounted. A drive assembly for driving the two conveyor belt assemblies is provided on one side of the conveyor belt mounting frame. One conveyor belt assembly is located below the screen hole, and the other conveyor belt assembly is located below one end of the inclined platform. The two conveyor belt assemblies are separated above each other by a partition frame, and the two ends of the partition frame are fixed to the conveyor belt mounting frame.

[0017] The beneficial effects of this invention are as follows: 1. This invention, by setting up a magnetic separation mechanism, enables construction waste to be first crushed by a crushing device and output to an inclined platform. Magnetic impurities are adsorbed onto the surface of an annular elastic sleeve, and as the structure rotates, the magnetic impurities are transported upwards. During this process, under the constraint of the support cylinder shape, the sliding seat slides on the sliding seat guide rod, and the strip-shaped sliding seat gradually moves closer to the center of rotation. At this time, the part of the annular elastic sleeve located above the curved guide part will deform due to gravity and the pressure of the impurities. Under the support of the inclined support plate, the annular elastic sleeve will tilt to one side while being concave. Because the distance between the strip-shaped sliding seat and the magnetic impurities increases, the magnetic attraction force is significantly reduced, and the magnetic impurities can slide away from one side along the inclined annular elastic sleeve. In this way, based on the rotation of the structure, a series of operations of adsorbing, lifting, and outputting magnetic impurities are realized.

[0018] 2. By setting up a vibration auxiliary spring and an auxiliary actuation mechanism, the present invention can transport construction waste to an inclined platform. Based on the operation of the auxiliary actuation mechanism, the inclined platform is driven to vibrate, so that the construction waste can slide down the inclined surface of the platform to achieve the purpose of transportation. Moreover, during the vibration of the inclined platform, the construction waste can be better lifted up, which helps to promote the magnetic separation of the magnetic separation mechanism.

[0019] 3. By setting ribs, the present invention can play a certain blocking role, preventing construction waste from sliding down the inclined platform too quickly, so as to facilitate more thorough magnetic separation. When the inclined platform vibrates, it will lift the building up to a certain height, so as to facilitate passing over the current rib and continuing to slide down.

[0020] 4. By setting up a transverse actuation mechanism, the present invention enables the ball head rod to periodically pass through the corrugated plate during the rotation of the rotating frame. Based on its shape characteristics, the corrugated plate can drive the connecting frame and the lever to make transverse reciprocating motion when squeezed by the ball head rod, with the cooperation of the return spring, thereby moving the passing construction waste left and right to facilitate better magnetic separation.

Detailed Implementation

[0023] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1: An automatic sorting and recycling device for construction waste, such as Figure 1-7 As shown, the device includes a crushing device (not shown in the figure), a first mounting frame 1, and a second mounting frame 2. A magnetic separation mechanism is mounted on the first mounting frame 1, and a ramp 5 is mounted on the second mounting frame 2. The output port of the crushing device is located above the ramp 5, and the magnetic separation mechanism is located above the ramp 5. The magnetic separation mechanism includes: A ring frame 14 is provided, and a rotating frame 28 is installed on one side of the ring frame 14. The rotating frame 28 is rotatably mounted on the first mounting frame 1, and the rotation center of the rotating frame 28 is matched with the center of the ring frame 14. A rotation drive unit is mounted on the first mounting bracket 1 and is used to drive the rotation bracket 28 to rotate. The support cylinder 26 and the first mounting frame 1 are in the shape of an inverted U-shape with the opening facing upward. The support cylinder 26 is fixed to the other end of the first mounting frame 1 by a bracket. An annular elastic sleeve 7 is fixed on the side of the annular frame 14 away from the rotating frame 28. The annular elastic sleeve 7 is located on the outside of the support cylinder 26. Based on the rotation of the annular frame 14, the annular elastic sleeve 7 rotates on the outer wall of the support cylinder 26. The slide guide rod 32 is fixed to the inner side of the ring frame 14. Multiple slide guide rods 32 are arranged in a circular pattern. A slide seat 31 is slidably connected to the outer wall of the slide guide rod 32. The slide seat 31 and the end of the slide guide rod 32 are connected by a slide spring 30. A strip slide 29 is installed on one side of the slide seat 31. An electromagnet is installed inside the strip slide 29. The support cylinder 26 includes an arc-shaped portion and a curved guide portion. The center of the arc-shaped portion is adapted to the rotation center of the ring frame 14. The curved guide portion is integrally set on the top of the arc-shaped portion. The two ends of the curved guide portion are smoothly transitioned to the arc-shaped portion. The middle part of the curved guide portion is recessed towards the center of the arc-shaped portion, forming an M-shaped structure. An inclined support plate 27 is fixed on the curved guide portion of the support cylinder 26. The inclined support plate 27 is located in the recess of the curved guide portion. The height of the inclined support plate 27 gradually decreases in the direction away from the ring frame 14. The strip slide 29 is pressed against and slides against the inner wall of the support cylinder 26 under the action of the slide spring 30. Since the structure needs to rotate during operation, the electromagnet can be connected to an external power supply system through components such as slip rings to meet the power supply requirements and avoid wire tangling. This is existing technology and will not be elaborated here. By setting up a magnetic separation mechanism, construction waste can be first crushed by a crushing device and output to the inclined table 5. During the process of construction waste passing through the inclined table 5, electromagnets are used to attract magnetic impurities onto the surface of the annular elastic sleeve 7. As the structure rotates, the magnetic impurities are transported upwards. Since the top of the support cylinder 26 has an M-shaped structure with the middle concave downwards and is equipped with an inclined support plate 27, the sliding seat 31 slides on the sliding seat guide rod 32 under the constraint of the shape of the support cylinder 26. The strip-shaped sliding seat 29 gradually moves closer to the center of rotation, while the annular elastic sleeve 7 is located at the curved... The portion above the guide section deforms due to gravity and the pressure of impurities. The inclined support plate 27 supports the annular elastic sleeve 7 in the deformed state, causing the annular elastic sleeve 7 to tilt to one side while being concave. Due to the presence of the inclined support plate 27 and the limitation of the strip slide 29, the distance between the strip slide 29 and the magnetic impurities is increased, the magnetic attraction force is significantly reduced, and the magnetic impurities can slide away from one side along the annular elastic sleeve 7 in the tilted state. In this way, based on the rotation of the structure, a series of operations such as adsorption, lifting, and output of magnetic impurities are realized.

[0026] To facilitate the rotation of the driving structure; such as Figure 3 As shown, the rotation drive unit includes a sorting drive motor 3, which is mounted on the first mounting frame 1 via a motor base. The output end of the sorting drive motor 3 is connected to a drive gear 22. A driven gear 6 is mounted on the shaft of the rotating frame 28, and the driven gear 6 meshes with the drive gear 22.

[0027] To better output magnetic impurities; such as Figure 3, Figure 5 As shown, a guide plate 16 is connected to the outer wall of one side of the top of the support cylinder 26. The cross-sectional shape of the guide plate 16 is adapted to the shape of the curved guide part of the support cylinder 26.

[0028] To facilitate the transport of construction waste; such as Figure 1 As shown, a guide slide rod 12 is fixed to the outer wall of the bottom of the inclined platform 5. The guide slide rod 12 is slidably connected to the inner wall of the second mounting frame 2. The guide slide rod 12 and the second mounting frame 2 are connected by a vibration auxiliary spring 13. An auxiliary actuation mechanism for promoting the vibration of the inclined platform 5 is installed on the second mounting frame 2.

[0029] To facilitate the vibration of inclined platform 5; such as Figure 2 As shown, the auxiliary actuation mechanism includes a cam motor 19, which is mounted on the outer wall of one side of the second mounting bracket 2. The output end of the cam motor 19 is connected to a cam 18. An end frame 17 is fixed at the bottom of the inclined platform 5 and is located on the movement path of the cam 18. By setting up a vibration auxiliary spring 13 and an auxiliary actuation mechanism, construction waste can be transported to the inclined platform 5. Based on the operation of the auxiliary actuation mechanism, the inclined platform 5 is driven to vibrate, so that the construction waste can slide down the inclined surface of the inclined platform 5 to achieve the purpose of transportation. Moreover, during the vibration of the inclined platform 5, the construction waste can be better lifted up, which helps to promote the magnetic separation of the magnetic separation mechanism.

[0030] To improve conveying efficiency; such as Figure 1 As shown, the inclined platform 5 is provided with ribs 4 distributed at equal intervals; By setting ribs 4, a certain blocking effect can be achieved to prevent construction waste from sliding down the inclined platform 5 too quickly, so as to facilitate more thorough magnetic separation. When the inclined platform 5 vibrates, it will lift the building up to a certain height, so as to make it easier to slide down past the current ribs 4.

[0031] To improve reliability; such as Figure 4 As shown, inclined baffles 33 are provided on both sides of the inclined platform 5. The two inclined baffles 33 are in an inverted octagonal structure; they serve to block and prevent construction waste from sliding down from both sides.

[0032] To improve the magnetic separation effect; such as Figure 3 , Figure 4As shown, a transverse actuation mechanism is installed on the inclined platform 5. The transverse actuation mechanism includes multiple connecting frames 25, each connected frame 25 is distributed between adjacent ribs 4, and multiple levers 23 are rotatably installed on the connecting frame 25. Transverse slides 20 are fixed at both ends of the connecting frame 25. The transverse slides 20 slide laterally on the inner wall of the inclined baffle 33. The transverse slides 20 and the inclined baffle 33 are connected by a return spring 24. A corrugated plate 21 is installed on the top of one transverse slide 20. Multiple ball joints 15 are installed on one side of the rotating frame 28. The corrugated plate 21 is located on the movement path of the ball joints 15. By setting up a lateral agitation mechanism, the ball head rod 15 can periodically pass through the corrugated plate 21 during the rotation of the rotating frame 28. Based on its shape characteristics, the corrugated plate 21 can drive the connecting frame 25 and the lever 23 to make lateral reciprocating motion when squeezed by the ball head rod 15, with the cooperation of the return spring 24, thereby moving the passing construction waste left and right to facilitate better magnetic separation.

[0033] To facilitate the sorting of small-sized construction waste; such as Figure 1 As shown, the inclined platform 5 has evenly distributed sieve holes 11, and a receiving and conveying mechanism is provided at one end of the inclined platform 5 and below the sieve holes 11.

[0034] For ease of receiving and transporting; such as Figure 1 As shown, the receiving and conveying mechanism includes a conveyor belt mounting frame 8, on which two conveyor belt assemblies 9 are mounted. A drive component, such as a conveyor belt motor, is provided on one side of the conveyor belt mounting frame 8 to drive the two conveyor belt assemblies 9. One conveyor belt assembly 9 is located below the screen hole 11, and the other conveyor belt assembly 9 is located below one end of the inclined platform 5. The two conveyor belt assemblies 9 are separated above each other by a separator frame 10, and both ends of the separator frame 10 are fixed to the conveyor belt mounting frame 8.

[0035] For the parts not disclosed in detail in this invention, those skilled in the art can ensure the smooth implementation of the solution of this invention based on common sense, normal logical thinking and existing technology.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
