TECHNICAL FIELD

[0001] The application belongs to the technical field of construction waste recycling, and particularly relates to a recycling device for high-rise construction waste. TECHNICAL BACKGROUND

[0002] With the growth of population and the continuous development of industrial society and commercial society, the land supply and per capita land possession are less and less. In order to improve the current situation of land shortage, high-rise buildings have become the mainstream trend. However, a large amount of construction waste such as concrete blocks, waste mortar and waste metal will be generated in the process of high-rise building construction. Under the action of wind, toxic substances and dust particles in the construction waste are easily diffused into the air, causing pollution to the ecological environment.

[0048] Embodiment One, see Figures 1-19 .

[0049] As Figure 1 , Figure 2 shown, a recycling device for high-rise building garbage includes a vertical transportation shaft 1 and energy reduction buffer devices and kinetic energy recovery devices inside the vertical transportation shaft 1.

[0050] In this embodiment, the vertical transportation shaft 1 with a square cross-section is located in the building shaft, and the four side walls of the vertical transportation shaft 1 are in contact with the side walls of the building shaft, providing support for the vertical transportation shaft through the building shaft, thereby preventing deformation and damage of the side walls of the vertical transportation shaft 1 caused by collision of the building garbage during falling.

[0051] As Figure 2As shown, the inside of the vertical transportation well 1 is spaced in the height direction with four same energy reduction buffer devices, i.e. the first energy reduction buffer device 2, the second energy reduction buffer device 3, the third energy reduction buffer device 4 and the fourth energy reduction buffer device 5. It is important to emphasize that in the embodiment, the four energy reduction buffer devices are respectively located at the four side walls of the vertical transportation well 1 and sequentially rise in the clockwise direction, i.e. the first energy reduction buffer device 2 is fixed to the left side wall of the vertical transportation well 1, the second energy reduction buffer device 3 is fixed to the rear side wall of the vertical transportation well 1, the third energy reduction buffer device 4 is fixed to the right side wall of the vertical transportation well 1, and the fourth energy reduction buffer device 5 is fixed to the front side wall of the vertical transportation well 1.

[0052] As shown in the first energy reduction buffer device 2, Figure 3 the first energy reduction buffer device 2 includes a fixed seat 21, a buffer plate 22 and an elastic support part 23 for supporting the buffer plate 22. In the embodiment, the fixed seat 21 is in the shape of a straight triangular prism, one side of which is welded to the left side wall of the vertical transportation well 1, so that the inclined surface faces the upper right. The buffer plate 22 is located above the fixed seat 21, and the size of the plate surface of the buffer plate 22 is consistent with the cross-sectional size of the vertical transportation well 1. One end of the buffer plate 22 is welded with a rotating shaft 221, and the front and rear side walls adjacent to the left side wall of the vertical transportation well 1 are both provided with rotating grooves with the same height and consistent with the diameter of the rotating shaft 221 (not shown in the figure), and the buffer plate 22 is rotationally connected to the front and rear side walls of the vertical transportation well 1 through the rotating shaft 221. It should be particularly noted that in the embodiment, the buffer plate 22 is made of a steel plate with spring steel, which can achieve a certain degree of energy dissipation effect through deformation during the stress process. In addition, the side surface of the rotating shaft 221 is close to the left side wall of the vertical transportation well 1 to ensure that the falling construction waste does not hit the fixed seat 21 and the elastic support part 23 below.

[0053] As shown in the first energy reduction buffer device 2, Figure 4 , Figure 5As shown, the elastic support 23 includes a telescopic cylinder 232 and a spring 231 located inside the telescopic cylinder 232. The bottom surface of the telescopic cylinder 232 is welded to the inclined surface of the fixed seat 21, and the fixed seat 21 provides support for the telescopic cylinder 232. The bottom end of the spring 231 is also welded to the inclined surface of the fixed seat 21, and the top end of the spring 231 is welded to the top plate 2321 of the telescopic cylinder 232. Under the action of external load, the buffer plate 22 rotates clockwise around the pivot 221 and transfers the external load to the spring 231. Since the direction of the external load is constantly changing, it cannot be guaranteed to always be perpendicular to the axis of the spring 231. Therefore, the spring 231, which has a weak bending resistance, will undergo deflection deformation under the action of external load. In severe cases, it will damage the structure of the spring 231, making the spring 231 unable to recover. To address this, a compressible telescopic cylinder 232 is provided on the outside of the spring 231. The inner wall of the telescopic cylinder 232 provides support for the spring 231, thereby limiting the deflection deformation of the spring 231 during the stress process and improving the load-bearing capacity and stability of the entire elastic support 23.

[0054] When construction waste falls to the bottom of the vertical transport shaft 1, although the multiple energy-reducing buffer devices at the top dissipate some of the kinetic energy during the fall, the construction waste about to hit the ground still carries a strong impact load. When the construction waste comes into contact with the ground or a rigid structural surface, the strong impact load will cause the construction waste to break severely and produce a large amount of dust, resulting in a low recycling rate. Therefore, it can be seen that the kinetic energy of construction waste is dissipated through impact and breakage, but it is not being utilized effectively.

[0055] Based on this, in this embodiment, a kinetic energy recovery device is added to the bottom of the vertical transport well 1. By recovering and converting the kinetic energy of the construction waste and using it to support the buffer plate 22, the load-bearing capacity of the energy-reducing buffer device is improved, while also sharing part of the load on the elastic support 23, thus extending the service life of the elastic support 23. It should be emphasized that in this embodiment, the kinetic energy recovery device and the energy-reducing device are in one-to-one correspondence.

[0056] Taking the first kinetic energy recovery device 6 as an example, such as Figures 6-12As shown, the device includes a first sliding block 61 slidably connected to the left side plate of the vertical transport well 1. The upper surface of the first sliding block 61 is inclined downward. Two first sliding grooves 62 of equal height and the same size are formed on the left side plate of the vertical transport well 1. In this embodiment, the two first sliding grooves 62 are symmetrical about the longitudinal centerline of the left side wall of the vertical transport well 1. A sliding protrusion 611 is welded to the back of the first sliding block 61. The length of the sliding protrusion 611 is the same as the width of the first sliding block 61. The first sliding block 61 is slidably connected to the first sliding groove 62 through the sliding protrusion 611. A return spring 63 is provided in the first sliding groove 62. The top end of the return spring 63 is welded to the bottom surface of the sliding protrusion 611, and the bottom end of the return spring 63 is welded to the bottom surface of the first sliding groove 62. Under the action of an external load, the first sliding block 61 slides downward along the height direction. When the external load decreases or disappears, the first sliding block 61 slides upward under the rebound action of the return spring 63.

[0057] The interior of the left side plate of vertical transport well 1 has openings such as Figure 13 , Figure 14 The first connecting groove 64 shown in this embodiment has two sections, symmetrical about the longitudinal centerline of the left side wall of the vertical transport well 1, and both sections are located between the two first sliding grooves 62. In this embodiment, the first connecting groove 64 extends from the bottom of the left side plate of the vertical transport well 1 to above the fixing base 21 in the first energy reduction buffer device 2. The bottom of the first connecting groove 64 has a first opening 641, and the top of the first connecting groove 64 has a second opening 642. The first connecting groove 64 communicates with the external space through the first opening 641 and the second opening 642. It is worth emphasizing that in this embodiment, the first opening 641 and the first sliding groove 62 are of the same height and size.

[0058] In order to achieve the kinetic energy recovery and conversion of construction waste, in this embodiment, as follows: Figures 15-18 As shown, a first rack 65 is welded to the back of the first sliding block 61. The meshing portion of the first rack 65 faces the first connecting groove 64. In this embodiment, the width of the first rack 65 is greater than the width of the first sliding block 61, thereby ensuring that the first rack 65 and the first sliding block 61 have sufficient stroke. A second rack 67 is provided in the first connecting groove 64. It should be noted that in this embodiment, the end of the second rack 67 near the first rack 65 is provided with teeth for meshing, namely, a meshing section 671. The meshing portion of the meshing section 671 faces the meshing portion of the first rack 65, and a transmission gear 66 is provided between the two. The length of the transmission gear 66 is the same as the width of the first opening 641, and both ends of the transmission gear 66 are provided with teeth such as... Figure 17The connecting shaft 661 shown has connecting holes (not shown in the figure) on both sides of the first opening 641. The transmission gear 66 is rotatably connected to the side walls of the first opening 641 through the two connecting shafts 661. The transmission gear 66 converts the downward displacement of the first rack 65 into the upward displacement of the second rack 67.

[0059] The top of the second rack 67 is bent toward the buffer plate 22, i.e., the bent section 672, and the top of the bent section 672 abuts against the bottom of the buffer plate 22. The middle part of the second rack 67 is the same size as the first connecting groove 64 and is in complete contact, i.e., the contact section 673. Under the action of external force, the contact section 673 of the second rack 67 and the first connecting groove 64 undergo relative displacement, but there is no misalignment between them.

[0060] It is important to emphasize that in this embodiment, the second rack 67 and the elastic support 23 provide tiered support for the buffer plate 22. The second rack 67 applies the first tier of support to the buffer plate 22. The first sliding block 61 and the first rack 65 are displaced downwards by the impact load of the construction waste, and the second rack 67 is driven upwards by the transmission gear 66. During this upward movement, the bent section 672 applies a pre-support force to the buffer plate 22, causing the buffer plate 22 to tend to rotate counterclockwise around the axis 221, or the buffer plate 22 to rotate counterclockwise around the axis 221. This pre-support force is essentially generated by the first kinetic energy recovery device 6 recovering and converting part of the kinetic energy of the construction waste. As construction waste continues to fall, the pre-support force provided by the first kinetic energy recovery device 6 to the buffer plate 22 can offset part of the impact load. When the impact load is greater than the pre-support force, causing the buffer plate 22 to rotate counterclockwise until the bottom surface of the buffer plate 22 contacts the top plate 2321 of the telescopic cylinder 232, the elastic support part 23 acts as the second-level support structure to provide elastic support to the buffer plate 22, further reducing the energy of the falling construction waste.

[0061] The pre-support force provided by the first kinetic energy recovery device 6 can serve as the first-level support to share part of the impact load for the elastic support part 23, reduce the working time and intensity of the elastic support part 23, thereby slowing down the aging and failure of the first energy reduction buffer device 2 and improving the service life of the first energy reduction buffer device 2.

[0062] It is worth emphasizing that, such as Figure 19 As shown, in this embodiment, the first sliding block 61 in the first kinetic energy recovery device 6, the second sliding block 71 in the second kinetic energy recovery device, the third sliding block 81 in the third kinetic energy recovery device, and the fourth sliding block 91 in the fourth kinetic energy recovery device together form a frame structure. The channel reserved in the middle can ensure that large-sized construction waste can pass through smoothly, thereby ensuring the smooth flow of the vertical transport well 1.

[0063] To facilitate the dumping of construction waste of varying heights, in this embodiment, an opening is provided above each energy-reducing buffer device as shown in the image. Figure 1 The waste dumping opening 11 shown ensures that construction waste, after being poured into the vertical transport well 1 through the waste dumping opening 11, falls onto the upper surface of the buffer plate 22 and descends along the plate surface. Additionally, a sliding closing plate is provided at the opening of the waste dumping opening 11, and sliding grooves are provided at the bottom and top of the waste dumping opening 11. The sliding closing plate is slidably connected to the side plate of the vertical transport well through the sliding grooves. The opening and closing of the waste dumping opening 11 is achieved through the sliding closing plate, ensuring that dust in the vertical transport well 1 does not diffuse out through the waste dumping opening 11. A handle is welded to the sliding closing plate for easy pulling during opening and closing.

[0064] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
