Description

Technical Field

[0001] This utility model relates to the field of precast concrete slab recycling technology, specifically to a waste PC precast concrete slab recycling device. Background Technology

[0002] Precast concrete (PC) slabs are widely used in construction projects. However, with the upgrading of buildings, a large number of PC slabs are being scrapped.

[0003] Currently, the usual method for processing scrapped precast concrete (PC) slabs is to first crush them to allow for the recycling of the materials. However, traditional manual crushing is time-consuming and labor-intensive, and after crushing, the reinforcing steel and concrete become mixed together, making separation very difficult. This results in low efficiency in steel recycling, increasing recycling costs and processing complexity. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a waste PC precast slab recycling device to solve the problem that the separation of reinforced concrete after the precast slab is broken is cumbersome and leads to difficulties in steel bar recycling.

After crushing, the base plate is controlled to flip downward, thereby separating the base plate from the cantilever arms. The concrete fragments piled on the base plate after crushing fall off, while the steel bars remain on the cantilever arms, thus separating the concrete from the steel bars. The steel bars on the cantilever arms are then collected. Through efficient crushing and convenient separation, the recycling efficiency of steel bars is improved, manual intervention and processing time are reduced, and labor costs are lowered.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a waste PC precast panel recycling device, which includes a box 1 with an opening on one side and multiple sets of cantilever arms 52 evenly distributed horizontally inside; a pressing unit, including a power component disposed on the top wall inside the box 1, and a bottom plate 5 hinged at one end inside the box 1. A limiting component is provided at the end of the bottom plate 5 away from the hinge point to keep the bottom plate 5 in a horizontal state. The multiple sets of cantilever arms 52 are respectively located between the power component and the bottom plate 5. The bottom plate 5 has rectangular grooves 504 with a number corresponding to the number of cantilever arms 52. When the bottom plate 5 is in a horizontal state, the multiple sets of cantilever arms 52 are located in the corresponding rectangular grooves 504. The bottom plate 5 is used to place waste PC precast panels, and the power component is used to press the waste PC precast panels on the bottom plate 5.

[0023] The detailed working process of this embodiment is as follows: the power component squeezes the scrapped PC precast slab placed on the base plate 5. Multiple sets of cantilever 52 cooperate with the base plate 5 to apply squeezing and shearing forces to the precast slab, which can fully crush the precast slab and separate the concrete from the internal steel bars. After crushing, the base plate 5 is controlled to flip downward, thereby separating the base plate 5 from the cantilever 52. The crushed concrete fragments piled on the base plate 5 fall off, while the steel bars remain on the cantilever 52, thereby separating the concrete from the steel bars. The steel bars on the cantilever 52 are then collected.

[0024] like Figure 1 As shown, the power component includes a hydraulic element 3 installed on the top wall inside the housing 1 and a pressure plate 31 installed at the output end of the hydraulic element 3. The pressure plate 31 has multiple sets of notches 311 evenly distributed around its perimeter. Guide rails 12 are installed on both sides inside the housing 1, and each guide rail 12 is located in the corresponding notch 311.

[0025] The detailed working process of this embodiment is as follows: The power component consists of a hydraulic element 3 and a pressure plate 31. The hydraulic element 3 is installed on the top wall inside the housing 1 and can provide a stable and adjustable pressure output to the pressure plate 31. Multiple sets of notches 311 evenly distributed around the pressure plate 31 cooperate with the guide rails 12 set on the two side walls inside the housing 1. The guide rails 12 are embedded in the notches 311, so that when the pressure plate 31 moves up and down under the drive of the hydraulic element 3, it can slide smoothly along the direction of the guide rails 12, ensuring the stability and accuracy of the movement of the pressure plate 31, and preventing the pressure plate 31 from deviating during the extrusion process, which would affect the extrusion effect on the scrapped PC precast panels.

[0026] In this embodiment, hydraulic component 3 is a hydraulic cylinder. In other embodiments, a suitable hydraulic device can be selected according to the actual situation.

[0027] like Figure 2 and Figure 4 As shown, the limiting component includes a first limiting rod 51. An adjustment groove 502 is provided at one end of the base plate 5 away from the hinge point. The first limiting rod 51 is located in the adjustment groove 502. Slide grooves 11 are provided on both sides of the box body 1. The two ends of the first limiting rod 51 are respectively located in each slide groove 11.

[0028] like Figure 4 As shown, each slide groove 11 includes an arc groove 111 and a limiting groove 112. When the base plate 5 is in a horizontal state, each limiting groove 112 overlaps with the adjusting groove 502, and the first limiting rod 51 is located in the limiting groove 112.

[0029] The detailed working process of this embodiment is as follows: With the setting of the first limiting rod 51, when the first limiting rod 51 is located in the limiting groove 112, it provides reliable horizontal limiting and ensures that the bottom plate 5 is kept in a horizontal position.

[0030] In the initial state, the first limiting rod 51 is located within the adjusting groove 502 and the limiting groove 112, firmly supporting the base plate 5 to remain horizontal, facilitating the placement of scrapped PC precast slabs. When the power component drives the pressure plate 31 to compress the precast slab, the first limiting rod 51 restricts the displacement of the base plate 5 within the limiting groove 112, ensuring a stable compression process. After compression is completed, the first limiting rod 51 is controlled to disengage from the limiting groove 112, and then the base plate 5 is pushed to rotate around the hinge point. At this time, the first limiting rod 51 will slide along the arc groove 111, disengaging from the constraint of the limiting groove 112, allowing the base plate 5 to rotate and separate the concrete from the reinforcing steel.

[0031] like Figure 3 As shown, limit rings 511 are provided near the two ends of the first limit rod 51, and each limit ring 511 is located outside the housing 1.

[0032] The detailed working process of this embodiment is as follows: with the setting of the limiting ring 511, the first limiting rod 51 is prevented from being pulled out during use.

[0033] like Figure 3 As shown, extrusion teeth 501 are provided on both opposite surfaces of the base plate 5 and the pressure plate 31.

[0034] The detailed working process of this embodiment is as follows: With the extrusion teeth 501 in place, when the PC precast panel is crushed by extrusion, its surface can first come into contact with the extrusion teeth 501, generating concentrated stress, which causes the concrete to crack and break from the contact point of the tooth tip, reducing the required pressure.

[0035] like Figure 3 As shown, each cantilever 52 is provided with a 523 column at the end near the opening, and each 523 column can pass through the corresponding notch 311.

[0036] The detailed working process of this embodiment is as follows: With the setting of column 523, the steel bars peeling off the concrete on the cantilever 52 are prevented from rolling down and affecting the efficiency of steel bar collection.

[0037] like Figure 1 As shown, the hinge on the opening side of the box 1 has a baffle 2, which is located at the bottom plate 5. A second limiting rod 21 is provided at the end of the baffle 2 away from the corresponding hinge point. The two side walls of the box 1 are provided with slots 15, and the second limiting rod 21 is located in the slots 15.

[0038] The detailed working process of this embodiment is as follows: With the baffle 2 in place, during the extrusion process, the baffle 2 can prevent broken concrete blocks and steel rebar fragments from flying out from the opening side, protecting the safety of the operators and reducing the amount of cleaning work around the equipment. When the baffle 2 is closed, the second limiting rod 21 slides into the slot 15 to prevent the baffle 2 from being opened by external force, thereby losing its effect.

[0039] like Figure 3 As shown, a magnetic suction device 14 is provided on the top of the box 1.

[0040] The detailed working process of this embodiment is as follows: With the magnetic attraction 14 in place, the baffle 2 can be flipped upward and abutted against the magnetic attraction 14. The magnetic attraction 14 is used to fix the baffle 2, thus avoiding interference with the placement of the precast slab.

[0041] like Figure 2 As shown, a collection box 4 is detachably installed at the bottom of the box 1.

[0042] The detailed working process of this embodiment is as follows: The function of the collection box 4 is to collect the crushed concrete debris.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
