Description

Technical Field

[0001] The present invention relates to the technical field of construction waste recycling, and in particular to a construction waste recycling and reprocessing device and a processing method thereof. Background Art

[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and stones and other wastes generated by construction units or individuals in the production activities of the construction industry such as demolition, construction, decoration and repair. With the continuous progress of the times, a large number of buildings are demolished every year, and a large amount of construction waste will be generated after demolition. Recycling and reuse equipment is needed to recycle the construction waste.

[0003] The defects of the garbage recycling device in the prior art are:

[0004] 1. Patent document CN218654627U discloses a device for processing, recycling and reusing urban construction waste. "It includes a shell, wherein symmetrically arranged crushing rollers are arranged inside the shell, and symmetrically arranged motors are fixedly installed on the left side of the shell. There are two motors, and rectangular blocks are fixedly installed on the right side of the output shafts of the two motors. A connecting sleeve is fixedly installed on the left side of the crushing roller, and the rectangular block cooperates with the connecting sleeve. In this utility model, by pulling the two handles, the fixing rod can release the cover plate, and the cover plate can be disassembled, and the shell can be opened. The crushing rollers can be directly taken out and replaced, and it is also convenient to clean the inside of the shell." The use position of the crushing rollers in this recycling and reuse device is fixed, and the distance between the crushing rollers cannot be adjusted according to the different specifications of the construction waste. It is easy to cause blockage in the shell and cannot ensure the crushing effect of the construction waste.

[0005] 2. Patent document CN215197213U discloses a construction waste recycling and reuse device, "including a machine body, the inner cavity of which is provided with a sorting and crushing mechanism, the sorting and crushing mechanism including an installation box, the inner cavity of which is movably connected to four sliding blocks, the inner cavities of the four sliding blocks are all fixedly installed with motors. The construction waste recycling and reuse device is provided with a sorting and crushing mechanism through the inner cavity of the machine body, and the sorting and crushing mechanism is provided with two sets of crushing rollers, which can be adjusted according to the size of the construction waste actually crushed. Among them, the upper set of crushing rollers will also sort the construction waste that falls between the crushing rollers when adjusting. The construction waste that meets the requirements falls on the crushing rollers for crushing, and the construction waste that does not meet the requirements is discharged from the first discharge port, thereby ensuring the high efficiency of the crushing and avoiding the crushing rollers crushing larger construction waste, which consumes a lot of time and affects the crushing efficiency. Finally, the crushed construction waste is discharged from the second discharge port." The stability of the crushing rollers of the recycling and reuse device after adjustment is poor. The vertical and horizontal bars will shake during the operation of the motor. The motor will become loose after long-term use, and the stability of the motor during operation cannot be guaranteed.

[0006] 3. Patent document CN216630994U discloses a device for recycling and reusing construction waste, "including a box body, in which two symmetrically arranged first crushing rollers are rotatably connected, a partition is fixedly connected to the box body and below the first crushing roller, and a through groove for garbage to pass through is provided on the partition, and two symmetrically arranged second crushing rollers are rotatably connected to the box body and below the partition, and the distance between the second crushing rollers is smaller than the distance between the first crushing rollers. This utility model pre-crushes larger garbage by using the first crushing roller, making it easier for the garbage to pass through the second crushing roller and reducing the damage to the crushing roller caused by the garbage, thereby improving the crushing efficiency and practicality." This recycling and reuse device only has the effect of crushing construction waste, and cannot perform primary classification of the crushed construction waste, which is not conducive to the subsequent processing of construction waste.

[0007] 4. Patent document CN218531078U discloses a construction waste recycling and reuse device that "is convenient for separating iron objects in construction waste so that they can be discharged by classification, avoiding manual sorting and reducing manpower. It has good overall usability and high practicality. It includes a crushing box, a support assembly is fixedly welded to the bottom end of the crushing box, a feed port is provided at the top of the crushing box, a feed pipe is fixedly welded inside the feed port, two mounting blocks are fixedly connected to the inner walls of the left and right sides of the crushing box, a strip groove is provided in the mounting block, two rotating shafts are rotatably arranged between the two strip grooves, crushing rollers are fixedly sleeved on the outside of the two rotating shafts, gear 1 is fixedly sleeved on the outside of the two rotating shafts located in the left strip groove, a tooth chain is connected between the two gears, and gear 2 is fixedly sleeved on the outside of one of the rotating shafts located in the right strip groove." This recycling and reuse device cannot automatically remove iron objects attached to the surface of the electromagnetic plate. The accumulation of iron objects reduces the electromagnetic plate's adsorption effect on iron objects in construction waste, and the good performance of the electromagnetic plate cannot be guaranteed.

[0017] Preferably, the working steps of the reprocessing device are as follows:

[0018] S1. First, construction waste is fed into the device through the feed tube. The first drive motor rotates the first crushing tube, and the second drive motor rotates the second crushing tube. The first crushing tube and the second crushing tube cooperate to crush the falling construction waste.

[0019] S2. The crushing motor drives the rotating rod to rotate so that the crushing teeth can further crush the construction waste after the initial crushing. The rotating motor drives the rotating roller to rotate continuously. The electromagnet works under the action of rotation to absorb the metal substances in the falling construction waste, and the rest of the waste falls onto the surface of the conveyor belt.

[0020] S3. The operation of the conveying motor drives the conveying roller to rotate. The conveying roller drives the conveyor belt to work continuously through the transmission effect of the pulley. The filter belt filters the large particles in the crushed construction waste. The completely crushed construction waste falls into the collection box through the filter belt. During the rotation of the conveyor belt, the scraper contacts the filter belt and scrapes off the large particles of construction waste on its surface.

The first electric telescopic rod pushes the adjustment block, which slides inside the limit slot and drives the mounting plate to adjust the position in the horizontal direction to adjust the distance between the first and second crushing drums. After the adjustment is completed, the second electric telescopic rod pushes the limit drum upward so that it engages with the inner side of the limit hole.

[0023] S12: The second driving motor will shake during operation. The mounting plate transmits the shaking impact force to the limit cylinder, which shakes slightly and contacts the contact pad. The contact pad drives the slide plate to move inside the slide groove and squeeze the shock-absorbing spring. The shock-absorbing spring buffers the transmitted impact force, and the damper prevents the slide plate from shaking continuously inside the limit frame.

[0024] In step S2, the following steps are also included:

[0025] S21. After the electromagnet has been used for a long time, the power to the electromagnet is cut off. The electric slider moves on the slide rail seat, driving the scraper ring to move horizontally so that the rubber scraper pad scrapes off the metal material attached to the surface of the electromagnet. The metal material is discharged to the outside of the device body through the discharge port.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention installs a mounting plate on the outside of the adjustment block, and adjusts the distance between the crushing barrel 1 and the crushing barrel 2 according to the different specifications of the construction waste. The electric telescopic rod 1 pushes the adjustment block, and the adjustment block slides inside the limit groove to drive the mounting plate to adjust the position in the horizontal direction to achieve the adjustment of the distance between the crushing barrel 1 and the crushing barrel 2. After the adjustment is completed, the electric telescopic rod 2 pushes the limit barrel to move upward so that it is engaged with the inner side of the limit hole. The distance between the crushing barrels is adjusted according to the different specifications of the construction waste, which effectively prevents blockage in the main body of the device and ensures the initial crushing effect of the crushing barrel 1 and the crushing barrel 2 on the construction waste.

[0028] The present invention installs a limiting frame on the back of the device body, and the driving motor 2 will shake during operation. The mounting plate transmits the shaking impact force to the limiting cylinder, and the limiting cylinder produces a slight shake and contacts the contact pad. The contact pad drives the slide plate to move inside the slide groove to squeeze the shock-absorbing spring. The shock-absorbing spring buffers the transmitted impact force, and the damper prevents the slide plate from shaking continuously inside the limiting frame, thereby ensuring the stability of the driving motor 2 during operation and extending the service life of the driving motor 2.

[0029] The present invention installs a filtering mechanism on the inner side of the device body, and the conveying motor drives the conveying roller to rotate. The conveying roller makes the conveyor belt work continuously through the transmission action of the pulley. The filter belt filters the large particles in the crushed construction waste. The completely crushed construction waste falls into the collection box through the filter belt. During the rotation of the conveyor belt, the scraper contacts the filter belt and scrapes off the large particles of construction waste on its surface. The large particles of construction waste that are not completely crushed are discharged through the slag discharge port. The classification and treatment of the crushed construction waste is beneficial to the subsequent processing of the construction waste, and improves the recycling and reprocessing efficiency of the construction waste.

[0030] The present invention installs a scraper ring on the opposite side of the electric slider. After the electromagnet is used for a long time, the electromagnet is powered off. The electric slider moves on the slide rail seat, driving the scraper ring to move in the horizontal direction so that the rubber scraper pad scrapes the metal material attached to the surface of the electromagnet. The metal material is discharged to the outside of the device body through the discharge port. The metal material attached to the surface of the electromagnet is automatically removed, avoiding the adverse effect of the accumulation of metal materials on the adsorption effect of the electromagnet, and ensuring the good performance of the electromagnet.

After the adjustment is completed, the electric telescopic rod 28 works to push the limit cylinder 29 to move upward so that it is engaged with the inner side of the limit hole 41. The driving motor 25 will shake during operation. The mounting plate 24 transmits the shaking impact force to the limit cylinder 29. The limit cylinder 29 produces a slight shake and contacts the contact pad 47. The contact pad 47 drives the slide plate 44 to move inside the slide groove 43 to squeeze the shock-absorbing spring 46. The shock-absorbing spring 46 buffers the transmitted impact force, and the damper 45 prevents the slide plate 44 from The inner side of the limit frame 42 is continuously shaken, and the crushing motor 3 is driven to rotate the rotating rod 30 so that the crushing teeth 31 further crush the construction waste after the preliminary crushing. The rotating motor 33 runs the rotating roller 4 and rotates continuously. The electromagnet 32 ​​works under the action of rotation to absorb the metal substances in the falling construction waste, and the remaining garbage falls on the surface of the conveyor belt 39. After the electromagnet 32 ​​is used for a long time, the electromagnet 32 ​​is powered off, and the electric slider 34 runs on the slide rail seat 5 to move and drive the scraper ring 35 to move in the horizontal direction so that the rubber scraper pad 36 touches the surface of the electromagnet 32. The metal materials attached to the surface are scraped off, and the metal materials are discharged to the outside of the device body 1 through the discharge port 17. The conveying motor 38 drives the conveying roller 37 to rotate, and the conveying roller 37 drives the conveyor belt 39 to work continuously through the transmission effect of the pulley. The filter belt 40 filters the large particles in the crushed construction waste. The completely crushed construction waste falls into the collection box 11 through the filter belt 40. During the rotation of the conveyor belt 39, the scraper 20 contacts the filter belt 40 and scrapes off the large particles of construction waste on its surface. The large particles of construction waste that are not completely crushed are discharged through the slag discharge port 18.
