Description

Technical Field

[0001] The invention relates to the technical field of construction waste recycling, and in particular to waste recycling equipment for construction engineering. Background Art

[0002] In building demolition projects, concrete and steel bars in construction waste can be recycled. During recycling, the concrete wrapped around the steel bars needs to be separated from the steel bars to achieve the recycling of the steel bars. The concrete is then crushed into the required particle size and reused as a building base material.

[0003] At present, hydraulic crushing pliers are often used to separate steel bars from concrete. Since most steel bars are irregularly curved, hydraulic crushing pliers can only crush and remove larger concrete blocks on the steel bars, and some concrete will still remain on the steel bars. This part of concrete is currently often removed by manual knocking, which has low processing efficiency. In addition, since the recycled steel bars are irregularly curved, the messy steel bars occupy a large volume, which makes recycling and transportation more difficult, and is also not conducive to the subsequent processing of steel bars. Usually, manual preliminary straightening of the steel bars is also used to facilitate the subsequent transportation and processing of the steel bars. Obviously, it is difficult to efficiently carry out large-scale concrete steel bar recycling operations. Therefore, a waste recycling equipment for construction projects is needed to solve the above problems. Summary of the invention

[0031] See also Figure 1-9, the present invention provides the following technical solutions:

[0032] A waste recycling device for construction engineering comprises: a frame 1, a panel 2 is installed on the frame 1, the upper end surface of the panel 2 is connected to a limit frame 3, the limit frame 3 is set as a "U"-shaped structure, which is used to limit reinforced concrete within a certain area, and can cooperate with a horizontal straightening mechanism 7 to horizontally straighten the steel bars; a screening plate 4 for filtering concrete debris is provided on the panel 2 in the area of ​​the limit frame 3, and the screening plate 4 is detachably installed on the panel 2. According to the use requirements of the concrete debris, the screening plates 4 with different filtering apertures can be replaced to achieve screening of concrete debris with different particle sizes.

[0033] A lifting drive mechanism 5 is installed on the panel 2. The lifting drive mechanism 5 includes a lifting plate 53 that can move up and down. The lifting plate 53 is connected with an installation box 6, and the installation box 6 can be used for vertical straightening of steel bars. The lifting drive mechanism 5 includes a guide column 51 connected to the four sides of the panel 2, an upper connecting plate 52 and a lifting plate 53. The upper connecting plate 52 is connected to the upper end of the guide column 51. The lifting plate 53 is slidably connected to the guide column 51. A first hydraulic cylinder 54 for driving the lifting plate 53 to move up and down is installed on the upper connecting plate 52. The setting of the lifting drive mechanism 5 can drive the installation box 6 to move up and down, so that the bottom of the installation box 6 presses down the steel bars to straighten the steel bars, and can drive the crushing mechanism 8 to contact the reinforced concrete waste.

[0034] A lower cover plate 62 is installed at the bottom of the installation box 6. The lower cover plate 62 is provided with an opening, and the crushing roller 81 is partially exposed from the opening. The arrangement of the lower cover plate 62 enables the installation box 6 to have a better downward pressing and straightening effect on the steel bars.

[0035] A horizontal straightening mechanism 7 is installed on the installation box 6 and is used to horizontally straighten the steel bars; the horizontal straightening mechanism 7 includes a transverse frame 71, a connecting frame 72 and a push plate 73 that slide horizontally in the installation box 6, the connecting frame 72 is installed at both ends of the transverse frame 71, the push plate 73 is installed at the lower end of the connecting frame 72, a slide groove is provided at the bottom of the push plate 73, a telescopic plate 74 is vertically slidably connected in the slide groove at the bottom of the push plate 73, a spring is provided in the slide groove for pushing the telescopic plate 74 downward, and a second hydraulic cylinder 75 for driving the transverse frame 71 to slide is installed on the installation box 6; the horizontal straightening mechanism 7 can also provide driving force for the crushing mechanism 8 while moving, without the need to add independent power equipment, so that the entire recycling equipment has a compact structure and is more energy-saving and environmentally friendly.

[0036] A crushing mechanism 8 is installed in the installation box 6. The crushing mechanism 8 includes a crushing roller 81 and a crushing protrusion 82. The crushing protrusion 82 is evenly distributed on the surface of the crushing roller 81. The crushing mechanism 8 is used to crush and clean the residual concrete on the surface of the steel bar; partitions 61 are provided at both ends of the installation box 6, and the crushing roller 81 is rotatably connected to the partition 61. The two axial ends of the crushing roller 81 are connected to a gear 83 through a one-way bearing. A driving block 84 is installed on the transverse frame 71, and a rack 85 that can mesh with the gear 83 is installed on the driving block 84; the purpose of setting the one-way bearing is that the rack 85 can only drive the crushing roller 81 to rotate during the squeezing process of the push plate 73 on the steel bar, so as to avoid the reversal of the crushing roller 81 so as to cause motion interference between the drive ring 93 and the connecting strip 91; the crushing mechanism 8 can grind and crush the residual concrete on the steel bar, so as to separate the concrete from the steel bar.

[0037] A vibration mechanism 9 is installed in the crushing roller 81. The vibration mechanism 9 is used for auxiliary removal of concrete on the surface of the steel bars and auxiliary filtering of concrete debris; the vibration mechanism 9 includes a connecting strip 91, a vibration column 92 and a driving ring 93. The crushing roller 81 is provided with a plurality of through grooves, and the arc surface of the crushing roller 81 is provided with through holes connected to the corresponding through grooves. The connecting strip 91 is slidably connected to the through grooves, and a plurality of the vibration columns 92 are connected to the connecting strip 91, and the vibration columns 92 are slidably connected to the through holes. A spring is provided in the through groove for pushing the impact column 92 to slide to the outside of the crushing roller 81. A driving ring 93 is installed on the mounting box 6 for driving the connecting strip 91 to slide and storing energy for the spring. The driving ring 93 is a circular ring with an opening, and an extended guide plate is provided at one end of the opening. When the crushing roller 81 rotates, it will drive the impact column 92 to knock the waste and the screening plate 4, and cooperate with the crushing of the crushing roller 81 to separate the concrete and the steel bars, and the screening plate 4 generates vibration to promote the concrete debris to pass through the screening plate 4, thereby promoting the screening of the concrete debris.

[0038] The working process of the present invention is as follows:

[0039] First, the reinforced concrete waste crushed by the hydraulic crushing pliers is placed on the screening plate 4, and the first hydraulic cylinder 54 is started. The first hydraulic cylinder 54 drives the lifting plate 53 to move downward, and the lifting plate 53 drives the installation box 6 to move downward. The lower cover plate 62 and the crushing roller 81 on the bottom of the installation box 6 squeeze the steel bars to achieve vertical straightening of the steel bars; after the installation box 6 is pressed down to a certain distance, the first hydraulic cylinder 54 stops running, and the second hydraulic cylinder 75 drives the transverse frame 71 to move horizontally. The transverse frame 71 drives the push plate 73 and the telescopic plate 74 to move through the connecting frame 72. The push plate 73 and the telescopic plate 74 cooperate with the limit frame 3 to squeeze the steel bars to achieve horizontal straightening of the steel bars, so that the steel bars are corrected to a relatively straight state, which is convenient for subsequent transportation and processing.

[0040] During the horizontal movement of the transverse frame 71, the transverse frame 71 drives the rack 85 to move horizontally through the driving block 84. When the rack 85 passes through the position of each gear 83, it will drive the gear 83 to rotate. The gear 83 drives the crushing roller 81 to rotate through the one-way bearing, so that the crushing protrusion 82 on the crushing roller 81 crushes the residual concrete blocks on the steel bars; during the rotation of the crushing roller 81, the crushing roller 81 drives the connecting strip 91 and the vibration column 92 arranged inside it to rotate, and the two ends of the connecting strip 91 slide in the driving ring 93. When the two ends of the connecting strip 91 rotate to the opening of the driving ring 93, the spring in the crushing roller 81 pushes the connecting strip 91 to slide rapidly in the through groove, so that the vibration column 92 pops out rapidly to vibrate the waste and the screening plate 4, thereby promoting the separation of concrete and steel bars, and at the same time promoting the screening of concrete debris.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
