Description

Technical Field

[0001] This invention belongs to the field of building concrete waste treatment technology, specifically a device for recycling and reusing building concrete waste. Background Technology

[0002] The recycling and reuse of construction concrete waste refers to the process of processing concrete waste, mainly composed of cement stone and aggregates, generated from building demolition and new construction projects. This involves crushing, screening, washing, and sorting to remove surface impurities and improve quality, transforming the waste into usable resources such as recycled aggregates. These recycled aggregates can then replace natural sand and gravel in building material production, achieving resource recycling, reducing landfill pollution, and conserving resources.

[0003] Existing water washing devices for recycling construction concrete waste often employ direct hydraulic rinsing or simple friction cleaning methods. This single-direction water flow fails to thoroughly clean all surfaces of the waste, creating blind spots. In actual washing, the large quantity and weight of the concrete waste make it difficult to move and tumble within the equipment, resulting in insufficient contact between the waste surface and the washing water. Consequently, impurities such as cement slurry and dirt adhering to the surface cannot be quickly and thoroughly washed away. This significantly reduces washing efficiency, prolongs the entire recycling process, and leaves the washed waste with a significant amount of residual impurities, failing to meet the quality standards for recycled aggregates.

[0004] The aforementioned problems directly lead to a significant decrease in the recycling efficiency of construction concrete waste. A large amount of larger waste that meets the recycling criteria cannot be effectively utilized due to inadequate washing and can only be disposed of by landfill. Therefore, improvements are needed. Summary of the Invention

[0005] To address the problems mentioned in the background section, the present invention provides a device for recycling and reusing construction concrete waste.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for recycling and reusing construction concrete waste, comprising a housing, and further comprising:

[0007] The drive module, located inside the housing, is used to filter construction concrete waste.

[0008] The contact module has multiple sets and is installed vertically inside the cavity of the box;

[0009] The drive module includes a mesh placed inside the cavity of the box, with a shaft rotatably connected to the top surface of the box at both ends of the mesh, and a half gear fixed to one end of the shaft.

[0010] The abutment module includes an abutment plate rotatably connected inside the box via a roller shaft, and the side wall of the abutment plate is attached to the mesh.

[0011] The construction concrete waste inside the box is effectively filtered by the mesh in the drive module, achieving preliminary separation of waste and fine materials, and making it easy to adjust the tension of the mesh and the filtration position.

[0012] Preferably, servo motors are fixedly connected to both sides of the upper end of the housing, and the output ends of the two servo motors are respectively fixedly connected to the corresponding shafts.

[0013] The speed and direction of the servo motor can be flexibly adjusted, thereby controlling the winding speed and tension of the mesh to meet the filtration needs of concrete waste with different particle sizes.

[0014] Preferably, the mesh is movably installed in the inner cavity of the box in a "U" shape;

[0015] The U-shaped mesh is located on both sides of the top horizontal end of the box cavity, and rotating components are installed on both sides.

[0016] The U-shaped mesh is located on both vertical ends inside the box cavity, which are in close contact with the inner wall of the box.

[0017] The mesh is designed in a "U" shape and is movably installed inside the box cavity, which greatly increases the contact area between the mesh and the concrete waste, improving the filtration efficiency. At the same time, the "U" shape structure can limit the waste and prevent it from falling from both sides of the mesh, ensuring comprehensive filtration.

[0018] Preferably, the mesh is detachably wound around the surface of the shaft, and the mesh diameter of the mesh is smaller than the size of the concrete waste placed on its surface.

[0019] The mesh diameter of the sieve is smaller than that of the concrete waste, which ensures that the waste is effectively intercepted on the sieve surface, achieving effective separation of waste from fine materials / impurities.

[0020] Preferably, one end of the roller shaft movably penetrates through the housing and extends to the outside of the housing, and the end of the roller shaft that movably penetrates inside the housing is fitted with a spring plate that allows the roller shaft to elastically return to its original position.

[0021] One end of the roller extends to the outside of the housing, facilitating connection with the external transmission structure and enabling synchronous drive of the roller. A spring plate is fitted at the end of the roller that passes through the inside of the housing, allowing the roller to be elastically reset using the elastic force of the spring plate. Even if the mesh is slightly deformed or shifted in position, the abutment plate will always remain in contact, ensuring the effective removal of waste residue from the mesh surface.

[0022] Preferably, a spur gear is fixedly sleeved at one end of the roller shaft extending to the outside of the housing, and the spur gear meshes with the shaft body;

[0023] The outer diameter of the spur gear is greater than that of the half gear.

[0024] By fixing a spur gear to one end of the outer side of the roller shaft and engaging the spur gear with the shaft body, synchronous linkage between the drive module and the contact module can be achieved. This eliminates the need for an additional drive structure, simplifies the overall structure of the device, and reduces manufacturing costs.

[0025] Preferably, the abutment module includes two sets of brush rollers disposed in the inner cavity of the box, wherein the size of the brush roller located above is larger than the size of the brush roller located below; one end of each set of brush rollers extends movably through to the outside of the box.

[0026] The two sets of brush rollers rotate vertically on the side wall of the box and are located in the middle area of ​​the mesh.

[0027] The contact module is equipped with two sets of brush rollers of different sizes, with the upper brush roller being larger than the lower one. This allows for graded cleaning of waste residue on the mesh surface. The larger upper brush roller can first scrape off larger pieces of waste residue from the mesh surface, while the smaller lower brush roller can further clean up any remaining fine waste residue and dust, improving the cleaning effect and preventing waste residue from clogging the mesh. The two sets of brush rollers rotate vertically and are located in the middle area of ​​the mesh, which can fully cover the filtration area of ​​the mesh, ensuring that there are no dead corners in the cleaning. At the same time, one end of the brush roller extends to the outside of the housing, which facilitates connection with the external transmission structure to achieve synchronous drive.

[0028] Preferably, one end of the brush roller extending to the outside of the housing is connected to the roller shaft via a belt drive;

[0029] The two sets of brush rollers are connected by belt drive.

[0030] The brush roller is connected to the roller shaft via a belt drive, enabling synchronous linkage of the internal structure of the contact module. This eliminates the need for additional drive components, simplifying the device structure and reducing manufacturing costs and maintenance difficulty.

[0031] Preferably, the rotating assembly includes a power motor fixed to the side wall of the housing;

[0032] The output end of the power motor is fixedly connected to a rotating shaft, and two pull ropes are detachably wound around the outer surface of the rotating shaft. The ends of the two pull ropes away from the rotating shaft are fixedly connected to the transverse end of the mesh located in the inner cavity of the box.

[0033] Preferably, the bottom end of the mesh and the bottom surface of the inner cavity of the box have a waste disposal area;

[0034] Discharge baffles are installed at the lower ends of both sides of the box.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] This invention utilizes a servo motor to drive a shaft, causing the mesh to wind and lift the waste upwards. This increases the contact friction of the construction concrete waste. Combined with the force of water washing, the repeated lifting and releasing of the mesh simulates a "rubbing" process, ensuring full contact between the surface of the construction concrete waste and the washing water, thus significantly improving washing efficiency.

[0037] This invention utilizes the meshing of a half-gear and a spur gear, combined with the resetting of a spring plate, to allow the abutment plate to intermittently strike the side wall of the net as it is lifted upwards. This squeezes the construction concrete waste inside the net, increasing the squeezing friction between the waste and enhancing the "rubbing force." Furthermore, two brush rollers extend into the central area of ​​the lifted net to deeply agitate and wipe the waste. This allows for thorough tumbling and movement within the box, ensuring more complete contact between the waste surface and the washing water. Cement slurry, dirt, and other impurities adhering to the surface of the concrete waste can be quickly and thoroughly washed away, significantly improving the washing efficiency.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] like Figures 1 to 8 As shown, the present invention provides a device for recycling and reusing construction concrete waste, including a housing 100, and further comprising:

[0054] The drive module 200, which is located inside the housing 100, is used to filter construction concrete waste.

[0055] The abutment module 500 has multiple sets and is installed vertically in the inner cavity of the housing 100;

[0056] The drive module 200 includes a mesh 240 placed in the inner cavity of the housing 100. The two ends of the mesh 240 are respectively wound with a shaft 230 rotatably connected to the top surface of the housing 100. One end of the shaft 230 is fixedly connected to a half gear 220.

[0057] The abutment module 500 includes an abutment plate 520 rotatably connected inside the housing 100 via a roller 510, and the side wall of the abutment plate 520 is in contact with the mesh 240.

[0058] The above scheme is adopted: the mesh 240 in the drive module 200 effectively filters the construction concrete waste in the box 100, realizing the initial separation of waste and fine materials. The shaft 230 can drive the mesh 240 to rotate, which facilitates the adjustment of the tension and filtration position of the mesh 240. The abutment plate 520 of the contact module 500 rotates through the roller 510 and fits tightly with the mesh 240, which can scrape off the waste attached to the surface of the mesh 240, avoid the mesh of the mesh 240 from being blocked, and ensure the filtration efficiency. At the same time, the half gear 220 can cooperate with the subsequent transmission structure to realize intermittent drive, reduce energy consumption, and ensure the stable operation of the device.

[0059] Servo motors 210 are fixedly connected to both sides of the upper end of the housing 100, and the output ends of the two servo motors 210 are fixedly connected to the corresponding shafts 230 respectively.

[0060] By adopting the above solution, servo motors 210 are fixedly connected to both sides of the upper end of the housing 100, and their output ends are fixedly connected to the shaft 230. This enables precise driving of the shaft 230. The speed and direction of the servo motors 210 can be flexibly adjusted, thereby controlling the winding speed and tension of the mesh 240. This adapts to the filtration needs of concrete waste with different particle sizes. Compared with manual driving, this not only reduces the labor intensity of manual labor, but also improves the stability and accuracy of the drive, avoiding the problem of poor filtration effect caused by uneven tension of the mesh 240.

[0061] The mesh 240 is installed in a "U" shape inside the cavity of the box 100;

[0062] The U-shaped mesh 240 is located in the inner cavity of the box body 100, and rotating components 300 are installed on both sides of the top surface of the horizontal end.

[0063] The U-shaped mesh 240 is located on both vertical ends inside the cavity of the box 100, and both ends are in contact with the inner wall of the box 100.

[0064] The above solution involves designing the mesh 240 in a "U" shape and movably installing it inside the housing 100. This significantly increases the contact area between the mesh 240 and the concrete waste, improving filtration efficiency. Simultaneously, the "U" shape helps to limit the waste, preventing it from falling from either side of the mesh 240 and ensuring comprehensive filtration. The vertical ends of the mesh 240 are movably fitted against the inner wall of the housing 100, preventing waste from leaking through the gap between the mesh 240 and the housing 100, thus ensuring filtration effectiveness. The rotating component 300 installed on the top surface of the horizontal end further drives the mesh 240, allowing it to shake up and down or move left and right, further cleaning the surface of the mesh 240 and preventing clogging of the mesh.

[0065] The mesh 240 is detachably wound around the surface of the shaft 230, and the mesh diameter of the mesh 240 is smaller than the size of the concrete waste placed on its surface.

[0066] The above solution involves a removable mesh 240 wound around the surface of the shaft 230, facilitating its disassembly, cleaning, and replacement. The specific installation and disassembly technology used can be selected based on the actual application scenario. When the mesh 240 experiences wear or mesh deformation, a new mesh 240 can be quickly replaced, reducing maintenance costs and extending the device's lifespan. The mesh diameter of the mesh 240 is smaller than that of the concrete waste, ensuring effective interception of the waste on its surface. This achieves effective separation of waste from fine materials / impurities, providing qualified raw materials for further crushing and reuse of the waste, and preventing fine materials from mixing into the waste and affecting reuse efficiency.

[0067] One end of the roller 510 movably passes through the housing 100 and extends to the outside of the housing 100. The end of the roller 510 that movably passes through the inside of the housing 100 is fitted with a spring plate 530 that allows the roller 510 to elastically return to its original position.

[0068] The above scheme is adopted: one end of the roller 510 extends to the outside of the box 100, which facilitates connection with the external transmission structure and realizes synchronous drive of the roller 510; a spring plate 530 is sleeved on one end of the roller 510 that penetrates the inside of the box 100. The elastic force of the spring plate 530 can realize the elastic reset of the roller 510, thereby driving the abutment plate 520 to always be in close contact with the mesh 240. Even if the mesh 240 undergoes slight deformation or positional displacement, the abutment plate 520 can always maintain the contact state, ensuring the scraping effect of waste residue on the surface of the mesh 240. At the same time, the spring plate 530 can buffer the impact force between the abutment plate 520 and the mesh 240, and prevent the mesh 240 from being damaged due to excessive force.

[0069] A spur gear 540 is fixedly sleeved at one end of the roller shaft 510 extending to the outside of the housing 100, and the spur gear 540 meshes with the shaft 230.

[0070] The outer diameter of the spur gear 540 is greater than that of the half gear 220.

[0071] The above solution involves fixing a spur gear 540 to one end of the outer side of the roller 510 and engaging it with the shaft 230. This enables synchronous linkage between the drive module 200 and the contact module 500, eliminating the need for an additional drive structure, simplifying the overall structure of the device, and reducing manufacturing costs. The outer diameter of the spur gear 540 is larger than that of the half gear 220, enabling speed reduction transmission. This results in the roller 510 rotating slower than the shaft 230, creating a relatively slow contact scraping action between the contact plate 520 and the mesh 240. This ensures effective scraping while preventing excessively fast scraping from causing wear on the mesh 240. Furthermore, the meshing of the half gear 220 and the spur gear 540 enables intermittent transmission, reducing energy consumption.

[0072] The abutment module 500 includes two sets of brush rollers 560 disposed in the inner cavity of the housing 100. The size of the upper brush roller 560 is larger than that of the lower brush roller 560. One end of each set of brush rollers 560 extends movably through to the outside of the housing 100.

[0073] Two sets of brush rollers 560 rotate vertically on the side wall of the box 100 and are located in the middle area of ​​the pull net 240.

[0074] The above solution involves two sets of brush rollers 560 of different sizes in the contact module 500, with the upper brush roller 560 being larger than the lower one. This allows for graded cleaning of waste residue on the surface of the mesh 240. The larger upper brush roller 560 can first scrape off larger pieces of waste residue from the surface of the mesh 240, while the smaller lower brush roller 560 can further clean up any remaining fine waste residue and dust, improving the cleaning effect and preventing waste residue from clogging the mesh. The two sets of brush rollers 560 rotate vertically and are located in the middle area of ​​the mesh 240, fully covering the filtration area of ​​the mesh 240 to ensure thorough cleaning. At the same time, one end of each brush roller 560 extends to the outside of the housing 100, facilitating connection with an external transmission structure for synchronous drive.

[0075] One end of the brush roller 560 extending to the outside of the housing 100 is connected to the roller shaft 510 via a belt 550.

[0076] The two sets of brush rollers 560 are connected by a belt 550.

[0077] The above solution involves connecting the brush roller 560 to the roller shaft 510 via a belt 550, achieving synchronous linkage of the internal structure of the contact module 500. This eliminates the need for additional drive components, simplifying the device structure and reducing manufacturing costs and maintenance difficulty. The connection between the two sets of brush rollers 560 via the belt 550 ensures that the two sets of brush rollers 560 rotate at the same speed, enabling coordinated cleaning and further improving the cleaning effect on the surface of the mesh 240. At the same time, the belt 550 transmission has a buffering effect, preventing the impact force generated during transmission from damaging the brush rollers 560 and roller shaft 510, thus extending the service life of the components.

[0078] The rotating assembly 300 includes a power motor 310 fixedly connected to the side wall of the housing 100;

[0079] The output end of the power motor 310 is fixedly connected to a rotating shaft 320. Two pull ropes 330 are detachably wound around the outer surface of the rotating shaft 320. The ends of the two pull ropes 330 away from the rotating shaft 320 are fixedly connected to the transverse end of the pull net 240 located in the inner cavity of the box 100.

[0080] The above solution is adopted as follows: The rotating component 300 is powered by the power motor 310, which drives the rotating shaft 320 to rotate. When the rotating shaft 320 rotates, it can wind or release the pull rope 330, thereby driving the horizontal end of the mesh 240 to move up and down, realizing the shaking of the mesh 240. This can effectively shake off the waste residue attached to the surface of the mesh 240, further preventing the mesh from clogging and improving the filtration efficiency. The pull rope 330 is detachably wound on the surface of the rotating shaft 320, which facilitates the replacement and maintenance of the pull rope 330. When the pull rope 330 is worn or broken, it can be quickly replaced without affecting the normal operation of the device. The two pull ropes 330 are symmetrically connected on both sides of the horizontal end of the mesh 240, which can ensure that the mesh 240 is subjected to uniform force and avoid deformation or damage to the mesh 240 due to uneven force.

[0081] The bottom of the mesh 240 and the bottom surface of the inner cavity of the box 100 have a waste disposal area.

[0082] Discharge baffles 400 are installed at the lower ends of both sides of the box 100.

[0083] The above solution employs the following: Waste residue placement areas are provided at the bottom of the mesh 240 and the bottom surface of the inner cavity of the housing 100. These areas can be used to collect concrete waste residue that has fallen after filtration and cleaning, facilitating centralized processing and reuse of the waste residue and preventing blockage of the inner cavity of the housing 100 due to waste residue scattering. Discharge baffles 400 installed at the lower ends of both sides of the housing 100 control the discharge speed and amount of waste residue, allowing operators to collect it according to actual needs. Simultaneously, the discharge baffles 400 can be closed when the device is not in operation to prevent dust and debris from entering the inner cavity of the housing 100, protecting internal components and extending the device's service life.

[0084] Working principle and usage process of this invention:

[0085] First, pour the construction concrete waste into the inner cavity of the box 100 so that it is located on the surface of the mesh 240, and then inject water into the box 100 so that the water washes away the construction concrete waste.

[0086] Subsequently, two servo motors 210 are controlled to run simultaneously via an external control terminal. The two servo motors 210 are of the same model. When the servo motors 210 are running, their output ends will cause the mesh 240 to be wound through the shaft 230. At this time, the mesh 240 will lift the construction concrete waste into the inner cavity of the box 100. At the same time, the power motor 310 will drive the pull rope 330 upward through the rotating shaft 320. The pull rope 330 will assist the bottom sides of the mesh 240 to pull upward, so that cement slurry, soil and other impurities can be filtered to the bottom of the mesh 240. At the same time, the discharge baffle 400 is pulled outward so that the initially filtered and more serious impurities are discharged first through the discharge baffle 400.

[0087] Subsequently, when the output end of the servo motor 210 rotates, it will synchronously drive the half gear 220 to rotate. The half gear 220 will mesh with the spur gear 540, causing the spur gear 540 to rotate synchronously. When the spur gear 540 rotates, it will drive the abutment plate 520 through the roller shaft 510 to pat the side wall of the upward-lifted net 240. At the same time, due to the half-side tooth design of the half gear 220, when the teeth of the half gear 220 do not mesh with the spur gear 540, the spring plate 530 will use its elasticity to cause the roller shaft 510 to drive the abutment plate 520 to reverse and reset. It should be noted that the elasticity of the spring plate 530 is sufficient to drive the brush roller 560 to rotate through the belt 550.

[0088] The forward and reverse rotation of the spur gear 540 causes the abutment plate 520 to intermittently pat the side wall of the mesh 240. When the mesh 240 picks up the waste residue, it pats and presses the waste residue inside the mesh 240, causing the waste residue to come into contact and rub against each other, and is thoroughly rinsed by water washing.

[0089] While the spur gear 540 rotates forward and backward, it also drives the brush roller 560 to rotate back and forth via the belt 550. Due to the different diameters, when the net 240 is lifted upward, the reciprocating rotation of the brush roller 560 squeezes and agitates the waste residue. Combined with water washing, the cleaning is more thorough.

[0090] It should be noted that both the mesh 240 and the rope 330 are made of highly wear-resistant materials and can be inspected and replaced regularly.

[0091] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0092] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
