Description

Technical Field

[0001] This invention belongs to the field of aluminum alloy formwork construction waste cleaning and recycling technology, specifically, it relates to a device for cleaning and recycling aluminum alloy formwork construction waste. Background Technology

[0002] Aluminum alloy formwork systems are widely used in the construction industry, particularly for high-rise residential buildings. Compared to traditional wooden formwork, aluminum formwork systems are more efficient, produce higher-quality concrete with better aesthetics, and can save costs for general contractors. However, one of the more common problems in aluminum formwork system construction is the recycling of pins and clips and the cleaning of debris at the bottom of beam reinforcement.

[0003] Currently, there is no established system for the recycling of pins and pin pieces. They are generally picked up manually to facilitate recycling and reuse between floors. In addition, because the debris at the bottom of the beam reinforcement affects the quality of subsequent concrete forming, construction workers usually use blowers to clean it up. However, this can only clean up small debris such as rust and slag, and often cannot clean it all up or pick it up completely, thus failing to meet the conditions for concrete pouring. The use of blowers in some areas also does not achieve the ideal effect. The main disadvantages are as follows: (1) Blowers have limitations and cannot clean up and pick up objects of slightly larger size that fall into the bottom of the beam reinforcement during construction. They often have to be cleaned up and picked up manually, which is inconvenient, time-consuming, and easy to scratch due to the dense reinforcement. Pins and pin pieces cannot be recycled, resulting in serious material waste. Construction workers are in a hurry to get to work, and pins and pin pieces that fall into narrow places are generally not dealt with, but are instead requested to be reshipped. Often, by the end of the project, the amount of pins and pin pieces used far exceeds the limit, resulting in serious waste. Summary of the Invention

[0004] This invention is a cleaning tool designed to assist in aluminum formwork construction. It primarily addresses the problem of pins and clips falling into inaccessible, confined spaces during the assembly of aluminum plate components such as walls, columns, and slabs in aluminum formwork systems, making retrieval difficult. Secondly, it also solves the problem of cigarette butts, water pipes, rust, and other debris remaining under the beam reinforcement after the aluminum alloy beam and slab formwork is assembled and the reinforcement is tied, which cannot be cleaned using a blower.

[0005] This invention is implemented as follows:

[0006] This invention provides a device for cleaning and recycling construction waste from aluminum alloy formwork, comprising a collection box, a cleaning adsorption pipe, a buffer platform, a conveyor belt assembly, and a separation assembly. The collection box has a square structure and is equipped with casters at its bottom for processing and recycling the adsorbed waste. The cleaning adsorption pipe, including at least one, is connected through the side wall of the collection box for adsorbing and cleaning waste from the aluminum alloy formwork. The buffer platform, the conveyor belt assembly, and the separation assembly are arranged inside the collection box. The buffer platform is positioned to cooperate with the port of the cleaning adsorption pipe to provide a buffering force for the waste adsorbed by the cleaning adsorption pipe, preventing it from damaging the components inside the collection box. The conveyor belt assembly is vertically offset from the collection box for conveying the adsorbed waste. The separation assembly is arranged along the running direction of the conveyor belt assembly for adsorbing magnetic objects in the waste and separating and collecting waste of different sizes.

[0007] The technical effects of the device for cleaning and recycling construction waste from aluminum alloy formwork provided by this invention are as follows: This device can clean and recycle waste from the gaps in aluminum alloy formwork and classify metal waste and large waste accordingly. Its advantages include:

[0008] By sorting and recycling waste, we can reduce the amount of waste going to landfills and being incinerated, thereby reducing environmental pollution and promoting the sustainable use of resources.

[0009] Metal waste can be effectively recycled, reducing the consumption of raw materials, lowering production costs, and promoting the recycling of resources.

[0010] This device can quickly remove debris from crevices, saving manual cleaning time and improving construction site efficiency. Timely removal of debris from crevices reduces potential hazards to workers and equipment, thus enhancing construction safety.

[0011] After sorting, waste transportation can be more efficient, reducing the cost of transporting multiple types of waste at the same time, thereby optimizing resource allocation.

[0012] This device can quickly and effectively clean up pins and pins that fall into confined spaces during the assembly of aluminum formwork, and effectively remove debris such as cigarette butts, water pipes and rust from under the beam reinforcement, creating a cleaner and tidier construction environment.

[0013] Based on the above technical solution, the device for cleaning and recycling construction waste from aluminum alloy formwork of the present invention can be further improved as follows:

[0014] The cleaning and adsorption tube includes a telescopic tube, a tube opening assembly, a sealing connection assembly, and an adsorption assembly. The telescopic tube includes at least one component, each tangentially positioned to the end of the buffer platform furthest from the conveyor belt assembly. The telescopic tube comprises two parts: a transmission tube located inside the collection box and a cleaning tube located outside the collection box for cleaning debris from the aluminum alloy template. The cleaning tube is a telescopic structure with pleated sidewalls to allow cleaning of aluminum alloy template positions at different distances. The tube opening assembly is fixedly connected to the end of the cleaning tube. The tube opening assembly includes a flat opening, a flared opening, and a straight opening, rotating according to the cleaning position. The tube opening assembly is fixedly connected to the end of the telescopic tube via threads. The conveying pipe is integrally connected to the cleaning pipe and is parabolic in shape inside the collection box. This allows waste to enter the collection box through the telescopic pipe by adsorption force, reducing resistance during the entire cleaning process. A sealing connection assembly is provided between the telescopic pipe and the side wall of the collection box to seal the connection between them. The adsorption assembly includes a fan impeller and a motor. The motor is located inside the collection box, and the shaft of the fan impeller is fixedly connected to the output shaft of the motor. The motor drives the fan impeller to rotate and generate negative pressure. A rotating platform is provided at the bottom of the fan impeller to change the angle by rotating it to correspond to the outlets of different numbers of telescopic pipes.

[0015] The beneficial effects of adopting the above-mentioned improved scheme are as follows: Having at least one telescopic pipe can disperse the garbage suction path, reducing the risk of blockage in a single pipe and ensuring smooth operation of the cleaning device. Telescopic pipes in different locations allow the cleaning device to work over a wider area, enabling rapid processing of debris in multiple areas, making it particularly suitable for large-scale construction sites. Multiple telescopic pipes can work simultaneously, thereby greatly improving the efficiency of garbage collection and reducing the time required for cleaning.

[0016] The telescopic conveyor tube is extendable and its length can be freely adjusted as needed, making users more flexible in various cleaning tasks and easily handling garbage in different locations. The adjustable length of the conveyor tube eliminates the need for bending over or excessive walking, reducing physical strain and improving work comfort.

[0017] The nozzle assembly has different replaceable structures, allowing for flexible replacement of nozzles with different structures according to different cleaning needs and environments, thus enhancing the vacuum cleaner's applicability and enabling it to adapt to various cleaning scenarios and tasks.

[0018] The flat opening design is suitable for cleaning narrow gaps and corners, allowing it to accurately enter confined areas for adsorption.

[0019] The flared design improves the efficiency of picking up large particles of debris (such as dust and debris), making it suitable for cleaning floors and large surfaces.

[0020] The flat-mouth design is suitable for cleaning large flat areas, providing stable suction and contact area, which is conducive to efficient cleaning.

[0021] Furthermore, the telescopic tube is equipped with a vortex generating component at the port of the transmission tube. The vortex generating component is used to rotate a sharp object from a horizontal to a vertical direction. The vortex generating component includes a guide plate and a vortex cavity. The guide plate is spirally arranged inside the telescopic tube, and the vortex cavity is located at the central axis of the guide plate. The inner wall of the vortex cavity is provided with a wear-resistant material to improve the wear resistance of the vortex cavity.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: When air flows through the suction pipe, the design of the deflector plate affects the airflow path. The deflector plate can guide the airflow in a specific direction, forming a vortex; within the vortex cavity, changes in airflow speed and pressure cause the airflow to rotate, thus forming a vortex structure; when a sharp object enters the vortex cavity, the vortex will subject it to airflow forces in different directions. The rotation and changes in airflow will cause sharp objects to be "pushed" from a lateral position to a vertical position, thereby preventing sharp objects from puncturing the telescopic pipe.

[0023] Furthermore, the fan impeller has an airfoil curve structure with a curved leading edge and a smooth trailing edge, which improves the flow efficiency of the fluid and generates a low-pressure zone when the gas flows through the fan impeller; the upper part of the fan impeller has a convex structure and the lower part has a concave structure, which improves the airflow distribution; and the tilt angle of the fan impeller is 10-30°.

[0024] Furthermore, the sealing connection assembly has an M-shaped structure, with its center pressed against the side wall of the collection box via the telescopic tube, and its bottom two sides tightly fitted to the side wall of the collection box; the sealing connection assembly is made of hard rubber.

[0025] Furthermore, the buffer platform includes a platform, a baffle plate, and a shock-absorbing spring. The platform is located at the port of the telescopic tube extending into the collection box, and is used to receive waste from the cleaning suction tube. The baffle plate is located at the front end of the platform, with a gap between it and the platform, and is used to prevent large pieces of construction waste from directly impacting the conveyor belt assembly. The shock-absorbing spring is located at the bottom of the platform, and is used to buffer the impact force when construction waste falls.

[0026] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the platform can prevent sucked-in waste from directly colliding with the conveyor belt, significantly reducing the impact force of objects on the conveyor belt, thereby reducing wear and damage to the conveyor belt and extending its service life. The baffle can effectively reduce the rebound and splashing of objects when they land, reducing potential hazards.

[0027] Furthermore, the conveyor belt assembly includes a conveyor belt, a drive roller, and a driven roller. The conveyor belt is located at the bottom of one side of the platform, with the drive roller and the driven roller positioned on both sides to drive the conveyor belt to rotate. The conveyor belt is made of a flexible and wear-resistant material, and its surface is provided with anti-slip textures to increase friction and prevent construction waste from slipping during transport. Several idlers are provided below the conveyor belt, and the idlers are evenly distributed below the conveyor belt to support the conveyor belt and reduce its running resistance.

[0028] Furthermore, the separation component includes a magnetic separation component, which is disposed on the side wall of the conveyor belt assembly. It is a permanent magnet component used to attract magnetic objects and metallic impurities transported on the conveyor belt assembly. The side wall of the conveyor belt assembly has a recessed structure, and the interior of the recess is used to store the attracted objects. The hard magnet component includes multiple permanent magnets arranged in a ring array, which are made of neodymium iron boron and are used to provide a stronger magnetic field strength.

[0029] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the magnetic separation component can quickly and effectively capture metal impurities on the conveyor belt, thereby performing preliminary separation of the sucked-in garbage. The rapid separation of metal objects makes the transportation process smoother.

[0030] Furthermore, the magnetic separation assembly also includes a weight separation assembly, which includes a fan assembly fixed to the side wall of the collection box and a separation box located at the bottom. A guide pipe is provided at the bottom of the air outlet of the fan assembly. The guide pipe has a parabolic structure, and its end is horizontally tangent to the center of the conveyor belt. This guide pipe is used to apply air force to the waste conveyed on the magnetic separation assembly to separate the waste according to weight. The separation box has a dividing mesh arranged from top to bottom. The mesh diameter gradually decreases as the height decreases, which is used to further separate the waste according to diameter.

[0031] The side wall of the collection box is provided with multiple air outlets, and a dustproof film is fixed on the air outlets to store dust inside the collection box.

[0032] The bottom sidewall of the separation box is connected to a vibration motor, which is used to clean the separation box by vibration to prevent blockage.

[0033] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the fan assembly can automatically blow lighter objects away from heavier objects, simplifying the sorting process, reducing manual intervention, and improving efficiency. After the lighter objects are blown away, more transport space can be provided for the heavier objects, making more rational use of the conveyor belt space. The separation box separates heavier debris according to size.

[0034] Furthermore, a pulley is provided on the side of the nozzle assembly away from the telescopic tube. The pulley is a universal wheel structure, which is used to facilitate the cleaning and adsorption tube to accurately adsorb the garbage on the aluminum alloy template.

[0035] Compared with existing technologies, the beneficial effects of the device for cleaning and recycling construction waste from aluminum alloy formwork provided by this invention are: this device can clean and recycle waste from the gaps in aluminum alloy formwork and classify metal waste and large waste accordingly. Its advantages include:

[0036] By sorting and recycling waste, we can reduce the amount of waste going to landfills and being incinerated, thereby reducing environmental pollution and promoting the sustainable use of resources.

[0037] Metal waste can be effectively recycled, reducing the consumption of raw materials, lowering production costs, and promoting the recycling of resources.

[0038] This device can quickly remove debris from crevices, saving manual cleaning time and improving construction site efficiency. Timely removal of debris from crevices reduces potential hazards to workers and equipment, thus enhancing construction safety.

[0039] After sorting, waste transportation can be more efficient, reducing the cost of transporting multiple types of waste at the same time, thereby optimizing resource allocation.

[0040] This device can quickly and effectively clean up pins and pins that fall into confined spaces during the assembly of aluminum formwork, and effectively remove debris such as cigarette butts, water pipes and rust from under the beam reinforcement, creating a cleaner and tidier construction environment.

The conveyor belt assembly 40 is staggered vertically with the collection box 10 for conveying the adsorbed waste. The separation assembly 50 is positioned along the running direction of the conveyor belt assembly 40 for adsorbing magnetic objects in the waste and separating and collecting waste of different sizes.

[0048] In the above technical solution, the cleaning and adsorption pipe 20 includes a telescopic pipe 21, a pipe opening assembly 22, a sealing connection assembly 23, and an adsorption assembly 24. The telescopic pipe 21 includes at least one component, which is tangentially arranged to the end of the buffer platform 30 away from the conveyor belt assembly 40. The telescopic pipe 21 includes two parts: a transmission pipe located inside the collection box 10 and a cleaning pipe located outside the collection box 10 for cleaning the waste on the aluminum alloy template. The cleaning pipe is a telescopic structure with a pleated sidewall, which is used to clean the aluminum alloy template at different distances. The pipe opening assembly 22 is fixedly connected to the end of the cleaning pipe.

The pipe opening assembly 22 is fixedly connected to the end of the telescopic pipe 21 by threads. The transmission pipe and the cleaning pipe are integrally connected. The transmission pipe is parabolic in shape inside the collection box 10, which allows the waste to enter the collection box 10 through the telescopic pipe 21 by the adsorption force and reduces the resistance during the entire cleaning process. A sealing connection assembly 23 is provided between the telescopic pipe 21 and the side wall of the collection box 10 to seal the connection between the telescopic pipe 21 and the collection box 10. The adsorption assembly 24 includes a fan impeller 241 and a motor 242. The motor 242 is located inside the collection box 10. The shaft of the fan impeller 241 is fixedly connected to the output shaft of the motor 242. The motor 242 drives the fan impeller 241 to rotate and generate negative pressure. A rotating platform is provided at the bottom of the fan impeller 241 to change the angle by rotation to correspond to the outlets of different numbers of telescopic pipes 21.

[0049] Furthermore, in the above technical solution, the telescopic tube 21 is provided with an eddy current generating component at the port of the transmission tube.

The eddy current generating component includes a guide plate and an eddy current cavity. The guide plate is spirally arranged inside the telescopic tube 21, and the eddy current cavity is located at the central axis of the guide plate. The inner wall of the eddy current cavity is provided with a wear-resistant material to improve the wear resistance of the eddy current cavity.

[0050] Furthermore, in the above technical solution, the fan impeller 241 has an airfoil curve structure with a curved leading edge and a relatively smooth trailing edge, which is used to improve the flow efficiency of the fluid and generate a low-pressure zone when the gas flows through the fan impeller 241; the upper part of the fan impeller 241 has a convex structure and the lower part has a concave structure, which is used to improve the airflow distribution; and the tilt angle of the fan impeller 241 is 10-30°.

[0051] Furthermore, in the above technical solution, the sealing connection component 23 has an M-shaped structure, with its center pressed against the side wall of the collection box 10 by the telescopic tube 21, and its bottom two sides tightly fitted to the side wall of the collection box 10; the sealing connection component 23 is made of hard rubber.

[0052] Furthermore, in the above technical solution, the buffer platform 30 includes a platform 31, a baffle plate 32, and a shock-absorbing spring 33. The platform 31 is located at the port of the telescopic pipe 21 that extends into the collection box 10, and is used to receive the garbage from the cleaning suction pipe 20. The baffle plate 32 is located at the front end of the platform 31, and there is a gap between it and the platform 31, which is used to prevent large pieces of construction waste from directly impacting the conveyor belt assembly 40. The shock-absorbing spring 33 is located at the bottom of the platform 31, and is used to buffer the impact force when the construction waste falls.

[0053] Furthermore, in the above technical solution, the conveyor belt assembly 40 includes a conveyor belt 41, a drive roller 42, and a driven roller 43. The conveyor belt 41 is located at the bottom of one side of the platform 31, and the drive roller 42 and driven roller 43 are located on both sides of it to drive the conveyor belt 41 to rotate. The conveyor belt 41 is made of a flexible and wear-resistant material, and its surface is provided with anti-slip texture to increase friction and prevent construction waste from slipping during the conveying process. Several idlers are provided below the conveyor belt 41, and the idlers are evenly distributed below the conveyor belt 41 to support the conveyor belt and reduce the running resistance of the conveyor belt.

[0054] Furthermore, in the above technical solution, the separation component 50 includes a magnetic separation component 51, which is disposed on the side wall of the conveyor belt assembly 40. It is a permanent magnet component used to adsorb magnetic objects and metal impurities transported on the conveyor belt assembly 40. The side wall of the conveyor belt assembly 40 has a recessed structure, and the interior of the recess is used to store the adsorbed objects. The hard magnet component includes multiple permanent magnets arranged in a ring array, which are made of neodymium iron boron and are used to provide a stronger magnetic field strength.

[0055] Furthermore, in the above technical solution, the magnetic separation component 51 also includes a weight separation component 52. The weight separation component 52 includes a fan assembly 521 fixed on the side wall of the collection box 10 and a separation box 522 set at the bottom. A guide pipe is provided at the bottom of the air outlet of the fan assembly 521. The guide pipe has a parabolic structure, and its end position is horizontally tangent to the center position of the conveyor belt 41. It is used to apply wind force to the garbage conveyed on the magnetic separation component 51 to separate the garbage according to weight. The separation box 522 has a dividing net arranged from top to bottom. The diameter of the dividing net gradually decreases as the height decreases. It is used to further separate the garbage according to diameter.

[0056] Multiple air outlets are provided on the side wall of the collection box 10, and a dustproof film is fixed on the air outlet to store dust inside the collection box 10.

[0057] The bottom sidewall of the separator 522 is connected to a vibration motor to clean the separator 522 through vibration to prevent blockage.

[0058] Furthermore, in the above technical solution, a pulley is provided on the side of the pipe assembly 22 away from the telescopic pipe 21. The pulley is a universal wheel structure, which is used to facilitate the cleaning of the adsorption pipe 20 to accurately adsorb the garbage on the aluminum alloy template.

[0059] In use, replace the nozzle assembly 22 according to the needs of the site and install the nozzle assembly 22 on the telescopic pipe 21. Adjust the length of the telescopic pipe 21 and align the nozzle assembly 22 with the area to be cleaned. Turn on the suction assembly 24. The fan impeller 241 works to generate negative pressure to suction the garbage in the gap of the aluminum alloy template. The garbage is sucked into the collection box 10 along the telescopic pipe 21 by the nozzle assembly 22. Due to the presence of the vortex generator, the angle of the sucked garbage is adjusted by the vortex generator to minimize the risk of the garbage puncturing the telescopic pipe 21. The garbage sucked into the collection box 10 falls onto the platform 31, which is designed to be inclined. After being buffered by the platform 31, the garbage gradually slides onto the conveyor belt assembly 40, which continuously transports the garbage. During the transport process, the magnetic separation assembly 51 attracts the metal garbage on the conveyor belt assembly 40 to both sides of the conveyor belt assembly 40. The fan assembly 521 continuously blows away the lighter garbage for separation, while the heavier garbage that cannot be blown away is transported by the conveyor belt assembly 40 into the separation box 522 for size separation.

[0060] Example 1:

[0061] Clean the pins under the beam reinforcement

[0062] First, ensure the device is connected to a power source and turned on. Select the flat-mouth nozzle assembly 22, ensuring it is tightly connected to the telescopic tube 21 to prevent air leakage. Slowly move the flat-mouth nozzle to the bottom of the beam reinforcement and visually inspect the pin's position. If the pin is visible in a narrow gap, use a flashlight for better observation. Gently insert the flat-mouth nozzle into the gap, maintaining a slight tilt angle for better access to confined spaces. Utilize the strong suction to instantly suck in the pin when it contacts the edge of the nozzle. For heavier or larger objects, slightly move the nozzle up and down to enhance the suction effect.

[0063] Example 2:

[0064] Clean cigarette butts and rust from the ground

[0065] First, ensure the device is connected to a power source and turned on. Select the flared nozzle assembly 22, ensuring it is tightly connected to the telescopic tube 21 to prevent air leakage. Aim the flared nozzle at the target object, maintaining a distance of approximately 5-10 cm, using its wide inlet to guide airflow. Gradually move closer to the target object, allowing the strong suction to draw in cigarette butts and rust. Gently move the nozzle to ensure multiple cigarette butts and rust are sucked in.

[0066] Specifically, the principle of this invention is as follows: In use, the nozzle assembly 22 is replaced according to the needs of the site and installed on the telescopic pipe 21. The length of the telescopic pipe 21 is adjusted so that the nozzle assembly 22 is aligned with the area to be cleaned. The adsorption assembly 24 is turned on, and the fan impeller 241 works to generate negative pressure to adsorb the garbage in the gap of the aluminum alloy template. The garbage is adsorbed by the nozzle assembly 22 and sucked into the interior of the collection box 10 along the telescopic pipe 21. Due to the presence of the vortex generating assembly, the angle of the sucked garbage is adjusted by the vortex generating assembly to minimize the risk of garbage poking. The waste, sucked into the collection box 10 after the expansion tube 21 breaks, falls onto the platform 31, which is designed to be inclined. The waste, after being buffered by the platform 31, gradually slides onto the conveyor belt assembly 40, which continuously transports the waste. During the transport process, the magnetic separation assembly 51 attracts the metal waste on the conveyor belt assembly 40 to both sides of the conveyor belt assembly 40. The fan assembly 521 continuously blows away the lighter waste for separation, while the heavier waste that cannot be blown away is transported by the conveyor belt assembly 40 into the separation box 522 for size separation.
