Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, specifically a pressing device for recycling construction waste. Background Technology

[0002] Construction waste refers to the excavated soil, materials, and other waste generated by construction units or individuals during the construction, demolition, repair, and decoration of various buildings and structures. The dumping of construction waste requires a large amount of land and necessitates its recycling and disposal.

[0003] In cement construction, films are used to cover cement and keep it moist. However, when the films are pressed and loaded for recycling, they may rebound and become tangled, which is not conducive to transportation. Therefore, a pressing device for construction waste recycling is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a pressing device for construction waste recycling, in order to solve the problem mentioned in the background art that when pressing and loading the film for recycling, it will rebound and easily become entangled, which is not conducive to transportation. To achieve the above objectives, this utility model provides the following technical solution: a pressing device for construction waste recycling, comprising a shell, a top cover movably connected to the top of the shell, a hydraulic push rod fixedly connected to the top of the top cover, the hydraulic push rod penetrating the top cover, a support plate threadedly connected to the other end of the hydraulic push rod, an energy storage assembly disposed on the top of the support plate, the energy storage assembly including a damping cylinder, a piston rod movably connected to the inner wall of the damping cylinder, the piston rod penetrating the support plate, a pressing assembly disposed at the bottom of the damping cylinder, the pressing assembly including a pressing top plate, a heating column fixedly connected to the bottom of the pressing top plate, a vent needle fixedly connected to the bottom of the pressing top plate, a heating wire disposed inside the pressing top plate, the heating wire being electrically connected to the heating column, a compression chamber fixedly connected to the inner wall of the shell, and a hinge threadedly connected to the bottom of the compression chamber. The other side of the hinge is threadedly connected to a second pressing component. The second pressing component includes a pressing base plate, a second heating column fixedly connected to the top of the pressing base plate, and a second heating wire installed inside the pressing base plate. The second heating wire is electrically connected to the second heating column. This pressing device for construction waste recycling heats the film waste with the heating column connected to the pressing top plate and the pressing base plate, causing the film to soften, reducing its hardness and toughness, while increasing friction to prevent the film from tangling. It effectively holds the film waste and prevents it from rebounding when the pressure changes. During pressing, the vent needle punctures the film, allowing the air inside the film to be smoothly discharged during compression. Under the action of pressing, the film waste will produce a certain degree of indentation deformation. After compression, the heated part of the film waste surface will harden due to cooling, making the structure of the film waste more compact and reducing the dragging phenomenon caused by the rebound and scattering of the film waste.

[0005] More preferably, a rubber baffle is fixedly connected to one side of the pressing top plate, and a rubber baffle is fixedly connected to one side of the pressing bottom plate. The rubber baffle is movably connected to the compression chamber. This pressing device for construction waste recycling prevents the film waste from being squeezed out from the edge and dragged outside the device by means of the rubber baffle. Moreover, the rubber baffle can adapt to different pressures and will not cause additional damage to the film waste.

[0006] In a further preferred embodiment, the piston rod is movably connected to a flange, the flange is threaded to the top of a support plate, a limiting cylinder is movably connected to the top of the piston rod, the other end of the limiting cylinder is fixedly connected to the bottom of the top cover, and a spring is movably connected to the side surface of the damping cylinder. This pressing device for construction waste recycling, through the spring, piston rod, and damping cylinder, reduces the excessive deformation and rebound of the film waste caused by sudden high pressure during pressing, and at the end of pressing, it can slowly release the pressure, allowing the film waste to recover its shape under controlled conditions, reducing rebound and dragging.

[0007] More preferably, the inner wall edge of the compression chamber is arc-shaped, and a feed inlet is fixedly connected to one side of the compression chamber. The other end of the feed inlet penetrates the shell. This type of compression device for construction waste recycling designs the inner corners of the chamber as arc-shaped, so that the film waste can pass smoothly through these areas when flowing in the chamber, reducing jamming and dragging.

[0008] In a further preferred embodiment, a bearing plate is movably connected to the bottom of the compression chamber, and the bearing plate is movably connected to the bottom of the pressing base plate. A second hydraulic push rod is fixedly connected to the bottom of the bearing plate, and a second support plate is fixedly connected to the other end of the second hydraulic push rod. In this pressing device for construction waste recycling, the bearing plate supports the pressing base plate. When the pressing is finished, the second hydraulic push rod moves the bearing plate away from the pressing base plate, causing the pressing base plate to open and allowing the compressed film waste to fall onto the bearing plate for discharge.

[0009] In a further preferred embodiment, a slider is fixedly connected to the bottom of the second support plate, the slider is engaged with a guide rail, the guide rail is fixedly connected to the inner wall of the housing, and a discharge port is provided on one side of the housing. This pressing device for construction waste recycling uses the guide rail to quickly remove the film waste that has fallen onto the support plate, which is beneficial for workers to load and transport the film waste.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In this invention, the heating column connecting the pressing top plate and the pressing bottom plate heats the film waste, causing the film to soften, reducing its hardness and toughness, while increasing friction to prevent the film from tangling. This effectively holds the film waste and prevents it from rebounding when pressure changes. During pressing, the vent needle punctures the film, allowing the air inside the film to be smoothly discharged during compression. Under the action of pressing, the film waste will produce a certain degree of indentation deformation. After compression, the heated part of the film waste surface will harden due to cooling, making the structure of the film waste more compact and reducing the dragging phenomenon caused by the rebound and scattering of the film waste.

[0012] In this invention, the rubber baffle prevents film waste from being squeezed out from the edge and dragged outside the device. The rubber baffle can adapt to different pressures and will not cause additional damage to the film waste. The energy storage component reduces the excessive deformation and rebound of the film waste caused by sudden high pressure when the film is pressed. At the same time, it can slowly release the pressure at the end of the pressing, so that the film waste can recover its shape under controlled conditions, reducing rebound and dragging.

[0025] In this embodiment, as Figure 4 , Figure 7 and Figure 9 As shown, a rubber baffle is fixedly connected to one side of the top plate and a rubber baffle is fixedly connected to one side of the bottom plate. The rubber baffle is movably connected to the compression chamber.

[0026] In this embodiment, as Figure 2 ,and Figure 5 As shown, the piston rod is movably connected to a flange, which is threaded to the top of the support plate. A limiting cylinder is movably connected to the top of the piston rod, and the other end of the limiting cylinder is fixedly connected to the bottom of the top cover.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the inner wall edge of the compression chamber is arc-shaped, and a feed inlet is fixedly connected to one side of the compression chamber, while the other end of the feed inlet penetrates the shell.

[0028] In this embodiment, as Figure 2As shown, a bearing plate is movably connected to the bottom of the compression chamber, and the bearing plate is movably connected to the bottom of the pressing base plate. A hydraulic push rod 2 is fixedly connected to the bottom of the bearing plate, and a support plate 2 is fixedly connected to the other end of the hydraulic push rod 2.

[0030] The method of use and advantages of this utility model: The pressing device for construction waste recycling operates as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the film waste enters the compression chamber 10 through the feed inlet 3. At this time, the hydraulic push rod 5 pushes the bearing plate 12 to close the pressing bottom plate 901 above the bearing plate 12. The hydraulic push rod 5 is activated, causing the support plate 6 connected to the bottom of the hydraulic push rod 5 to move downward, causing the pressing top plate 801 connected to the flange 704 and the limiting cylinder 705 to move downward to press the film waste. When the pressing top plate 801 contacts the film waste, the spring 703 is compressed to absorb part of the pressure, reducing the sudden high pressure that could cause the film waste to deform excessively and rebound. At this time, the heating columns 802 and 902 connected to the pressing top plate 801 and the pressing bottom plate 901 start to heat, causing the film to soften and reduce its hardness and toughness. At the same time, the heating columns can increase the friction to prevent the film from tangling and effectively hold the film waste to prevent it from rebounding when the pressure changes. During the pressing process, the vent needle 8... 03. Contact with the film, puncture the film to allow air inside the film to be smoothly discharged during compression. Under the action of compression, the film waste will undergo a certain degree of indentation and deformation due to the heating column, and the heated part of the film waste surface will harden due to the cooling effect, making the structure of the film waste more compact and reducing the rebound of the film waste. When the compression ends, the spring 703, piston rod 702 and damping cylinder 701 release a certain force, which can slowly release the pressure, allowing the film waste to recover its shape under control, further reducing rebound and dragging. At this time, the hydraulic push rod 2 13 stops supporting the compression base plate 901, and the bearing plate 12 connected to it drops a certain distance. The compression base plate 901 opens automatically under the influence of gravity, allowing the compressed film waste to fall onto the bearing plate 12. The film waste is sent out from the discharge port 4 by the support plate 2 14 connected to the hydraulic push rod 2 13 sliding on the guide rail 16.
