Description

Technical Field

[0001] This invention relates to the field of concrete waste recycling technology, specifically a device for recycling concrete waste from bridge construction. Background Technology

[0002] Concrete, often simply called PT, is a general term for engineering composite materials made by binding aggregates together with cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water in a specific ratio. It is widely used in civil engineering. During the production of commercial concrete, some excess concrete is often generated, such as residual concrete in the concrete mixer. If this residual wet concrete is discharged indiscriminately, it can easily damage the environment. Therefore, excess concrete is generally recycled by separating and returning the sand and gravel to the system for further batching. Currently, most existing bridge construction concrete waste recycling devices directly recycle the crushed waste material without separating the incompletely crushed waste residue. This not only reduces the quality of the recycled waste product but also affects the effectiveness of the recycled waste material. Summary of the Invention

[0014] (1) For the concrete surplus material recycling device for bridge construction of the present invention, the surplus material is pushed by the pushing plate to move repeatedly on the leakage sieve mesh, which helps the qualified surplus material to quickly pass through the screening of the leakage sieve mesh and accelerates the speed of the qualified surplus material being poured out from the output pipe; while the unqualified surplus material slag can be automatically pushed and gathered by the pushing plate and uniformly poured out through the slag dropping square opening, realizing the automatic screening of the qualified surplus material and the surplus material slag and the automatic gathering and discharging function of the surplus material slag.

[0015] (2) For the concrete surplus material recycling device for bridge construction of the present invention, through the guiding wall, the surplus material can be helped to gather and accumulate at the position where the auxiliary biting wheel and the active biting wheel bite in the middle, playing a role of centralized guidance for the surplus material; and in the process of crushing and biting the surplus material, the advantage that the guiding wall is arranged near the feeding port on the upper inner side of the tank body can be utilized to intercept and resist all the dust and debris splashed when the surplus material is broken, realizing the function of less dust and no splashing treatment of the tank body for the surplus material.

[0029] Example 1:

[0030] like Figure 1-9As shown, this invention discloses a bridge construction concrete waste recycling device, comprising a support 3, a tank 1 mounted vertically on the support 3, a material guiding assembly 2, and a material discharging assembly 4 disposed on the outside of the tank 1. The tank 1 has openings at the top and bottom, with the upper opening being the inlet and the lower opening being the outlet. A driving biting wheel 7 and an auxiliary biting wheel 6 are inserted side-by-side on the upper inner side of the tank 1, meshing with each other. A second composite biting wheel 9 and a first composite biting wheel 8, respectively meshing with the driving biting wheel 7 and the auxiliary biting wheel 6, are inserted side-by-side at intervals on the lower inner side of the tank 1. A drive motor 5 is mounted on the driving biting wheel 7. A W-shaped window 15 with stop teeth 16 is opened on one side of the tank 1 below the second composite biting wheel 9 and the first composite biting wheel 8. When the drive motor 5 drives the driving biting wheel 7 to rotate, the driving biting wheel 7 can drive the auxiliary biting wheel 6 and the second composite biting wheel 9 to rotate, and the auxiliary biting wheel 6 in turn drives the first composite biting wheel 8 to rotate. The material discharging assembly 4 is located on the outside of the tank 1. The material assembly 4 includes a W-shaped biting member 10 that is fitted into the W-shaped window 15. The W-shaped biting member 10 is equipped with a telescopic drive device, and the W-shaped biting member 10 can move back and forth under the action of the telescopic drive device. The material guiding assembly 2 includes a hopper 26 installed at the bottom of the tank body 1 and a funnel 23 fixedly installed at the bottom of the hopper 26. Pushing plates 21 that are adapted to the inner wall of the hopper 26 and can be telescopically scraped inside the hopper 26 are respectively provided on both sides of the hopper 26. A sieve 22 for filtering and screening the crushed concrete residue is provided at the bottom of the hopper 26. A slag discharge square opening 27 is provided through one side of the sieve 22 for discharging the residue. An output pipe 24 is installed on the funnel 23 for exporting qualified concrete residue. A slag discharge pipe 25 connected to the top of the slag discharge square opening 27 is installed on one side for directly discharging the residue from the hopper 26.

[0031] In this embodiment, the bracket 3 is designed in a "7" shape according to the structure of the overall recycling device. A front extension plate 31 for carrying the material guiding component 2 and the tank body 1 is provided at the front side of the bottom end thereof. The rear end of the driving motor 5 is arranged at the top end of the bracket 3, and its output end is connected to the active biting wheel 7. The funnel 23 is arranged on the front extension plate 31. Further, the telescopic driving device includes three hydraulic cylinders 42 arranged on the bracket 3. Hoop cylinders 11 are respectively arranged at both ends and the middle part of the W-shaped biting member 10. The telescopic ends of the three hydraulic cylinders 42 are respectively installed and connected to the three hoop cylinders 11 of the W-shaped biting member 10 through pins. When the three hydraulic cylinders 42 extend or retract simultaneously, the W-shaped biting member 10 can be driven to extend or retract on the W-shaped window 15. To protect the retracted W-shaped biting member 10, a W-shaped rear cover 41 adapted to the W-shaped biting member 10 is arranged on the outer side of the tank body 1 at the position of the W-shaped window 15. The telescopic ends of the three hydraulic cylinders 42 respectively penetrate through the W-shaped rear cover 41 and are connected to the three hoop cylinders 11 of the W-shaped biting member 10. In this embodiment, the whole of the W-shaped biting member 10 shields and semi-wraps the lower part of the first composite biting wheel 8 and the second composite biting wheel 9, and neither of them meshes with the W-shaped biting member 10, that is, there is a gap between the bottom of the first composite biting wheel 8 and the second composite biting wheel 9 and the W-shaped biting member 10 for the crushed residue to be crushed between the composite biting wheel structure and the biting wheel structure in the gap.

[0032] In this embodiment, a guiding wall 12 is further arranged inside the tank body 1 near the top opening, and a barbed wall 13 is arranged on the inner side wall below the guiding wall 12.

[0033] In this embodiment, an inverted groove opening 14 is provided at the middle position of the tank body 1 on one side of the W-shaped window 15.

[0034] In this embodiment, telescopic rods 28 connected to the two pushing plates 21 respectively penetrate through the front and rear sides of the hopper body 26. The telescopic rods 28 are used to drive the pushing plates 21 to move back and forth inside the hopper body 26 manually or by connecting to other telescopic mechanisms.

[0035] During use, the concrete residue is fed into the tank body 1 from the upper part. The driving motor 5 is started to drive the active biting wheel 7 to mesh and drive with the auxiliary biting wheel 6, so that the active biting wheel 7 and the auxiliary biting wheel 6 rotate towards the middle where they mesh simultaneously, and the active biting wheel 7 and the auxiliary biting wheel 6 are used to jointly perform the first crushing bite on the residue; then, the meshing drive of the second composite biting wheel 9 and the active biting wheel 7, the meshing drive of the first composite biting wheel 8 and the auxiliary biting wheel 6 are utilized, and combined with the兜住 and intercepting effect of the W-shaped biting member 10 on the crushed residue, the first composite biting wheel 8 and the second composite biting wheel 9 are used to perform rotary meshing crushing between the W-shaped biting member 10, the auxiliary biting wheel 6 and the active biting wheel 7 to complete the second crushing of the residue.

[0036] After the second crushing of the remaining material is completed, the drive motor 5 is turned off and the hydraulic cylinder 42 is started. The W-shaped bit 10 is taken into the W-shaped rear cover 41 through the W-shaped window 15. The remaining material stuck on the W-shaped bit 10 is blocked and scraped into the bottom of the tank 1 by the baffle teeth 16. While scraping and cleaning the remaining material on the W-shaped bit 10, the crushed remaining material is introduced into the bucket 26.

[0037] After the residual material is introduced into the hopper 26, the two sets of pusher plates 21 move back and forth alternately within the hopper 26, sieving the residual material through the screen 22 into the funnel 23. The qualified concrete residue filtered by the screen 22 is then discharged through the output pipe 24 for recycling. Residual material that cannot pass through the screen 22 is pushed by the pusher plates 21 into the slag discharge port and discharged through the slag discharge pipe 25. Depending on the actual situation, the residual material can be re-crushed during the next residual material recycling operation to improve the concrete residue recovery rate, or it can be directly discarded.

[0038] In this process, the first compound biting wheel 8 is engaged by the auxiliary biting wheel 6 and rotates clockwise; the second compound biting wheel 9 is engaged by the active biting wheel 7 and rotates counterclockwise. Under these conditions, the residue that was crushed in the first stage can be crushed by reverse biting between the first compound biting wheel 8 and the auxiliary biting wheel 6, and between the second compound biting wheel 9 and the active biting wheel 7, thereby increasing the biting and crushing effect of the two compound biting wheel structures on the residue. Furthermore, the synchronous upward flipping crushing motion trajectory of the first compound biting wheel 8 and the second compound biting wheel 9 above the W-shaped biting member 10 can continuously push and crush the residue stacked on the W-shaped biting member 10 upward. In addition, with the help of the two counter-rotating compound biting wheels, the residue that is statically piled up on the W-shaped biting member 10 can be squeezed and crushed at close range. This achieves three crushing and squeezing methods for the residue, comprehensively improving the crushing effect of the residue, and also has a backflow crushing effect on the residue, effectively eliminating hard lumps in the residue, and improving the recycling effect and quality of the residue.

[0039] Furthermore, the W-shaped biting element 10 intercepts at the bottom of the two composite biting wheel structures and also serves as a discharge valve structure inside the tank 1. It is used to discharge the material after the remaining material has been crushed, while preventing the incompletely crushed remaining material from falling into the hopper 26 and causing unnecessary losses. In addition, it replaces the original discharge structure, saving manufacturing costs.

[0040] During use, the recycling device can perform two consecutive crushing processes on the leftover concrete material and sequential close-range relative meshing crushing. The second crushing process can also be set to a reverse backflow meshing crushing process, which can promptly crush and compress hard blocks in the leftover material, improving the processing efficiency of hard block leftover material and improving the recycling efficiency of leftover material.

[0041] The pusher plate 21 pushes the residual material to move repeatedly on the sieve screen 22, helping qualified residual material to pass through the sieve screen 22 quickly and accelerating the speed at which qualified residual material is poured out from the output pipe 24; while unqualified residual material residue can be automatically pushed and gathered by the pusher plate 21 and poured out through the slag discharge port, realizing the automatic screening of qualified residual material and residual material residue, and realizing the automatic gathering and discharge function of residual material residue.

[0042] The guide wall 12 helps the residual material to gather and accumulate at the midpoint of the engagement between the auxiliary biting wheel 6 and the active biting wheel 7, thus providing a concentrated guiding effect for the residual material. Furthermore, during the crushing and biting process of the residual material, the guide wall 12, located near the feed inlet on the upper inner side of the tank body 1, can effectively intercept and block all dust and debris splashes generated during the crushing of the residual material, thereby achieving the function of minimizing dust and preventing splashes in the tank body 1.

[0043] The barbed wall 13 further prevents dust from overflowing to the top of the tank 1, and together with the guide wall 12, it provides a double barrier against dust. The groove 14 also helps the guide wall 12 to block dust from the side, preventing a large amount of dust from being thrown out from the top of the tank 1 and polluting the environment.

[0044] Example 2:

[0045] Based on Embodiment 1, the present invention provides a bridge construction concrete waste recycling device, wherein a first toothed rod 44 and a second toothed rod 45 are installed side by side on the outer side of the tank body 1, which are respectively connected to a first composite biting wheel 8 and a second composite biting wheel 9. A conveyor belt 46 is meshed between the first toothed rod 44 and the second toothed rod 45, and a second motor 43 is installed on the first toothed rod 44.

[0046] During use, when the first compound biting wheel 8 and the second compound biting wheel 9 are rotating upwards together and crushing the residual material through backflow meshing, if hard residual material gets stuck between the auxiliary biting wheel 6 and the active biting wheel 7 and the first compound biting wheel 8 and the second compound biting wheel 9, the small motor 43 can be started to drive the first toothed rod 44 to provide additional counterclockwise rotation power to the second compound biting wheel 9. This increases the biting force of the four biting wheel structures on the hard residual material, achieving full crushing of the hard residual material and eliminating the jamming phenomenon, ensuring smooth crushing and recycling of concrete residual material by the recycling device.
