Description

Technical Field

[0001] The present invention relates to the technical field of building material recycling, and in particular to a low-carbon building construction material recycling device and a use method thereof. Background Art

[0020] A method for using a low-carbon building construction material recycling device comprises the following steps:

[0021] S1: First, place the device at a suitable position on the construction site. When the ground is uneven and the device is in an unstable state, rotate the rectangular block first. The rectangular block drives the screw rod to rotate out from the bottom of the support box while rotating, and pushes the base and the rubber anti-skid pad at the bottom to the ground until it contacts the ground. Then, rotate and adjust the rectangular blocks at different positions in turn to make the device as a whole reach a horizontal and stable state. After adjustment, turn the locking nut to move the locking nut upward on the screw rod until it contacts the bottom of the support box to lock the position of the screw rod.

[0022] S2: Then, the construction waste is put into the crushing box, and the motor is started. The motor output shaft drives one of the rotating rods to rotate. When the rotating rod rotates, it drives the driving gear on it to rotate. When the driving gear on it rotates, it drives the meshing driven gear to rotate synchronously, so that the two rotating rods rotate synchronously in opposite directions. The crushing tooth knives outside the two rotating rods begin to crush the construction waste and break it into smaller particles or fragments.

[0023] S3: During the crushing process, one of the rotating rods drives the rotating shaft to rotate synchronously, and the rotating shaft drives synchronous wheel 1 to rotate, and synchronous wheel 1 rotates, and synchronous wheel 2 rotates through the synchronous belt, and synchronous wheel 2 rotates, and the eccentric rod rotates, and the rotation of the eccentric rod drives the driving rod to move, and the movement of the driving rod drives the connecting rod to reciprocate up and down, thereby driving the frame to slide outside the support rod to move up and down, and the up and down movement of the frame enables the screen frame 1 and the screen frame 2 to screen the crushed waste, and waste particles of different sizes fall into the supporting box below through the screen holes of different sizes. During the screening process, the magnet can absorb metal impurities in the waste, which is convenient for subsequent separation and treatment.

[0024] S4: The screened waste falls into the support box and then is discharged through the discharge pipe. It can be collected and reused. When the waste falls into the support box, the fan is started. The fan sucks the dust through the suction box and then discharges clean air after filtering through the filter element. The filter element can be regularly disassembled, cleaned or replaced to maintain its filtering effect.

[0025] S5: The vibration generated during the operation of the device will be transmitted to the top seat through the supporting box, causing the top seat to slide on the base. At this time, the damper itself uses internal friction or resistance to slow down the movement of the top seat when it is vibrated, consuming vibration energy, thereby effectively absorbing and slowing down the vibration generated by the device during operation. The buffer spring is mounted on the outside of the damper, and through its own elastic principle, it buffers the vibration, which can not only enhance the shockproof effect and reduce the vibration generated by the device during operation, but also reduce the noise generated by the device during operation.

[0026] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0027] The beneficial effects of the present invention are:

[0028] The invention improves the efficiency and quality of waste treatment by setting up the crushing mechanism. It can crush construction waste into fine particles quickly and effectively, laying a solid foundation for subsequent screening and recycling, which not only promotes the maximum utilization of resources, but also significantly reduces the environmental burden.

[0029] The present invention realizes accurate classification of crushed waste particles through the setting of screening components, improves the recovery quality and reuse efficiency of waste, and also provides a more convenient and accurate operation basis for subsequent waste treatment, further enhancing the environmental protection function and practical value of the device.

[0030] In the present invention, the synchronization of crushing and screening is achieved through the setting of the linkage mechanism, which not only improves the efficiency of waste treatment, but also ensures the continuity and automation of the process, effectively reduces labor costs, and improves the functionality and practicality of the overall equipment.

[0031] The present invention realizes an efficient and automated process for waste treatment through the cooperation of a crushing mechanism, a screening assembly and a linkage mechanism, which not only greatly improves the recycling rate of waste resources, but also simplifies the operating process, reduces energy consumption and labor costs, and demonstrates excellent environmental and economic benefits.

[0046] Example 1

[0047] Reference Figure 1-6 , a low-carbon building construction material recycling device and a method of use, comprising:

[0048] A support box 1, four support rods 2, a frame 3, a crushing box 4, a discharge pipe 19, a crushing mechanism, a screening assembly and a linkage mechanism. The support box 1 serves as the main structure, and four support rods 2 are fixed on the top thereof. The frame 3 is slidably arranged on the outside of the four support rods 2. The crushing box 4 is fixed on the top of the support rod 2 for receiving and processing construction waste, and the discharge pipe 19 is connected to one side of the support box 1 for discharging processed waste. The interior of the support box 1 is inclined for easy discharge of waste.

[0049] The crushing mechanism includes two rotating rods 6 symmetrically arranged inside the crushing box 4, each rotating rod 6 is fixed with a plurality of evenly distributed crushing tooth knives 7, and the crushing tooth knives 7 on the two rotating rods 6 are staggered to ensure that the waste can be fully crushed. The motor 10 is fixed on one side of the crushing box 4, and its output shaft is fixedly connected to a rotating rod 6 to drive it to rotate. The two rotating rods 6 extend to the outside of the crushing box 4. One end is fixed with a driving gear 8 and a driven gear 9, which are meshed and driven, so as to realize the synchronous rotation of the two rotating rods 6, so that the plurality of crushing tooth knives 7 can crush the waste.

[0050] The screening assembly includes reset springs 5 ​​which are sleeved on the top and bottom ends of the four support rods 2. These reset springs 5 ​​provide restoring force and buffering force for the up and down movement of the frame 3. One side of the frame 3 can be detached longitudinally and has a screen frame 1 20 and a screen frame 2 21 sliding through them. They are used to screen waste particles of different sizes, respectively. Magnets 22 are fixed at the center of the screen frame 1 20 and the screen frame 21 for absorbing metal impurities in the waste. In order to facilitate the replacement and cleaning of the screen frames, handles are fixed on one side of them. In addition, an accordion cover 34 is fixed to the outside of the reset spring 5 to prevent waste and dust from splashing out of the device.

[0051] The linkage mechanism includes a rotating shaft 11 fixed to one end of one of the rotating rods 6, a synchronous wheel 12 is fixed on the rotating shaft 11, a fixed frame 14 is fixed to one side of the supporting box 1, a synchronous wheel 2 15 is rotatably set on the fixed frame 14, and is connected to the synchronous wheel 12 through a synchronous belt 13, an eccentric rod 16 is fixed to one side of the synchronous wheel 2 15 at a position off-center, a driving rod 17 is rotatably set on the eccentric rod 16, one end of the driving rod 17 is rotatably connected to a connecting rod 18, and the other end of the connecting rod 18 is rotatably connected to the frame 3. When the rotating rod 6 rotates, the frame 3 is driven to slide on the support rod 2 and move up and down through the linkage mechanism, thereby realizing screening.

[0052] In order to reduce dust pollution during the waste treatment process, a suction box 23 is fixedly connected to one side of the support box 1, and a fan 24 is fixedly arranged on one side of the suction box 23. When the fan 24 is working, the dust will be sucked in through the suction box 23, and the clean air will be discharged after being filtered through the filter element 26. The filter element 26 is detachably arranged on the plug-in frame 25, which is convenient for regular cleaning or replacement.

[0053] Example 2

[0054] Based on the first embodiment, the second embodiment also includes

[0055] Reference Figure 7 , a low-carbon building construction material recycling device and a method of use, comprising:

[0056] In order to ensure the stability of the device during operation, the bottom of the support box 1 is rectangular and threaded with four screw rods 27, the bottom end of each screw rod 27 is fixed with a rectangular block, and the bottom of the rectangular block is rotatably provided with a top seat 28. The outsides of the four screw rods 27 are threaded with locking nuts 29 for locking the position of the screw rods 27. When the device is placed on an unstable ground, the height of the screw rods 27 can be adjusted by rotating the rectangular block to make the device reach a horizontal and stable state, and then the locking nut 29 is tightened to lock the position of the screw rod 27.

[0057] In order to reduce the vibration and noise generated by the device during operation, a base 30 is slidably provided at the bottom of the four top seats 28, and a damper 31 is fixedly provided inside the top seat 28 and the base 30. The bottom of the damper 31 is fixedly connected to the base 30, and the piston end is fixedly connected to the top seat 28. A buffer spring 32 is provided on the outside of the damper 31, and the two ends of the buffer spring 32 are respectively fixedly connected to the top wall of the top seat 28 and the bottom wall of the base 30. When the device vibrates, the damper 31 and the buffer spring 32 will work together to slow down the vibration and reduce the noise.

[0058] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 10 and the fan 24 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0059] The working principle and use process of the technical solution are as follows: first, place the device at a suitable position on the construction site. When the ground is uneven and the device is in an unstable state, first rotate the rectangular block. While rotating, the rectangular block drives the screw rod 27 to rotate out from the bottom of the support box 1, and pushes the base 30 and the rubber anti-skid pad 33 at the bottom to approach the ground until they are against the ground. Then, the rectangular blocks at different positions are rotated and adjusted in turn to make the device as a whole reach a horizontal and stable state. After adjustment, the locking nut 29 is screwed so that the locking nut 29 moves upward on the screw rod 27 until it is against the bottom of the support box 1 to lock the position of the screw rod 27.

[0060] Then, the construction waste is put into the crushing box 4, and the motor 10 is started. The output shaft of the motor 10 drives one of the rotating rods 6 to rotate. The rotating rod 6 drives the driving gear 8 thereon to rotate while the driving gear 8 thereon rotates. The driven gear 9 meshing with the driving gear 8 rotates while the two rotating rods 6 rotate synchronously, so that the two rotating rods 6 rotate synchronously, and the crushing tooth knives 7 outside the two rotating rods 6 begin to crush the construction waste and break it into smaller particles or fragments.

[0061] During the crushing process, one of the rotating rods 6 drives the rotating shaft 11 to rotate synchronously, and the rotating shaft 11 drives the synchronous wheel 12 to rotate while the rotating shaft 11 rotates. While the synchronous wheel 12 rotates, it drives the synchronous wheel 2 15 to rotate through the synchronous belt 13. While the synchronous wheel 2 15 rotates, it drives the eccentric rod 16 to rotate. The rotation of the eccentric rod 16 drives the driving rod 17 to move. While the driving rod 17 moves, it drives the connecting rod 18 to reciprocate up and down, thereby driving the frame 3 to slide outside the support rod 2 to move up and down. The up and down movement of the frame 3 enables the screen frame 1 20 and the screen frame 2 21 to screen the crushed waste. Waste particles of different sizes fall into the supporting box 1 below through the screen holes of different sizes. During the screening process, the magnet 22 can absorb metal impurities in the waste, which is convenient for subsequent separation and treatment.

[0062] The screened waste falls into the support box 1 and is then discharged through the discharge pipe 19, and can be collected and reused. When the waste falls into the support box 1, the fan 24 is started, and the fan 24 sucks the dust through the suction box 23, and then the clean air is discharged after being filtered by the filter element 26. The filter element 26 can be regularly disassembled, cleaned or replaced to maintain its filtering effect;

[0063] The vibration generated during the operation of the device will be transmitted to the top seat 28 through the support box 1, causing the top seat 28 to slide on the base 30. At this time, the damper 31 itself uses internal friction or resistance to slow down the movement of the top seat 28 when it is vibrated, thereby consuming vibration energy, thereby effectively absorbing and slowing down the vibration generated by the device during operation. The buffer spring 32 is mounted on the outside of the damper 31, and through its own elastic principle, it buffers the vibration, which can not only enhance the shockproof effect and reduce the vibration generated when the device is working, but also reduce the noise generated when the device is working.

[0064] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.

A low-carbon building construction material recycling device according to claim 7, characterized in that: A base (30) is slidably arranged at the bottom of the four top seats (28); a damper (31) is fixedly arranged inside the top seats (28) and the base (30); the bottom of the damper (31) is fixedly connected to the base (30); the piston end of the damper (31) is fixedly connected to the top seat (28); a buffer spring (32) is sleeved on the outside of the damper (31); the two ends of the buffer spring (32) are respectively fixedly connected to the top wall of the top seat (28) and the bottom wall of the base (30); and a rubber anti-skid pad (33) is fixedly arranged at the bottom of the four bases (30).

9. A method for using a low-carbon building construction material recycling device, characterized in that: A low-carbon building construction material recycling device comprising any one of claims 1 to 8, The following steps are involved: S1: First, place the device at a suitable position on the construction site. When the ground is uneven and the device is in an unstable state, first rotate the rectangular block. While rotating, the rectangular block drives the screw rod (27) to rotate out from the bottom of the support box (1) and pushes the base (30) and the rubber anti-skid pad (33) at the bottom to the ground until they are against the ground. Then, the rectangular blocks at different positions are rotated and adjusted in turn so that the device as a whole reaches a horizontal and stable state. After adjustment, the locking nut (29) is screwed so that the locking nut (29) moves upward on the screw rod (27) until it is against the bottom of the support box (1) to lock the position of the screw rod (27). S2: Construction waste is then put into the crushing box (4), and the motor (10) is started. The output shaft of the motor (10) drives one of the rotating rods (6) to rotate. The rotating rod (6) drives the driving gear (8) thereon to rotate. The driving gear (8) thereon drives the meshing driven gear (9) to rotate synchronously, so that the two rotating rods (6) rotate synchronously in opposite directions. The crushing tooth knives (7) outside the two rotating rods (6) begin to crush the construction waste into smaller particles or fragments. S3: During the crushing process, one of the rotating rods (6) drives the rotating shaft (11) to rotate synchronously. The rotating shaft (11) drives the synchronous wheel 1 (12) to rotate simultaneously. The synchronous wheel 1 (12) drives the synchronous wheel 2 (15) to rotate through the synchronous belt (13). The synchronous wheel 2 (15) drives the eccentric rod 16 to rotate simultaneously. The rotation of the eccentric rod (16) drives the driving rod (17) to move. The driving rod (17) drives the connecting rod (18) to reciprocate up and down, thereby driving the frame (3) to slide outside the support rod (2) to move up and down. The up and down movement of the frame (3) causes the screen frame 1 (20) and the screen frame 2 (21) to screen the crushed waste. Waste particles of different sizes fall into the support box 1 below through the screen holes of different sizes. During the screening process, the magnet 22 can absorb metal impurities in the waste, which is convenient for subsequent separation and treatment. S4: The screened waste falls into the support box (1) and is then discharged through the discharge pipe (19) and can be collected and reused. When the waste falls into the support box (1), the fan 24 is started. The fan 24 sucks the dust through the suction box 23 and then discharges clean air after filtering through the filter element 26. The filter element 26 can be regularly disassembled, cleaned or replaced to maintain its filtering effect. S5: The vibration generated during the operation of the device is transmitted to the top seat (28) through the support box (1), so that the top seat (28) slides on the base (30). At this time, the damper (31) itself slows down the movement of the top seat (28) when it is vibrated through internal friction or resistance to consume vibration energy, thereby effectively absorbing and slowing down the vibration generated by the device during operation. The buffer spring (32) is sleeved on the outside of the damper (31) and buffers the vibration through its own elastic principle, which can not only enhance the shockproof effect and reduce the vibration generated when the device is working, but also reduce the noise generated when the device is working.
