Description

Technical Field

[0001] This invention relates to the field of construction waste recycling technology, and more specifically, to a construction waste recycling device and method. Background Technology

[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and stones, and other waste generated during the production activities of the construction industry, such as demolition, construction, decoration, and repair. Classified by source, construction waste can be divided into engineering slag, decoration waste, demolition waste, and engineering mud; classified by composition, it can be divided into slag, concrete blocks, crushed stone, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metals, and waste bamboo and wood.

[0003] Currently, the main method for handling construction waste is to crush it to facilitate centralized transportation and subsequent processing. For construction waste containing scrap metal, after crushing, it often needs to be compressed into blocks to effectively reduce the transportation space it occupies. However, during the handling process, since there is no strong bond between the scrap metal pieces, if there are no relevant cross-linking points during deformation, there is a high probability that the compressed blocks will become loose or some non-metallic fragments will fall off the compressed blocks due to bumps and drops during transportation. This will affect the transportation process and / or impact the external environment and workers. Summary of the Invention

[0010] As a further optimization of the present invention, the hydraulic pushing assembly includes a housing second, a movable plate slidably connected to the inner wall of the housing second, a connecting frame connected to the lower end of the movable plate, and a hydraulic cylinder third fixedly connected to the frame. The housing second is fixedly connected to the frame, one end of the connecting frame is located outside the housing second, and a tension / compression sensor is connected between the output end of the frame and the connecting frame.

[0014] A method for recycling construction waste, using a construction waste recycling device as described above, includes the following steps: Step 1: The amount of construction waste to be recycled is fed into the crushing mechanism, which crushes the construction waste. The crushed material falls into the crushed material storage component. Step 2: The compression component pushes the scrap material in the scrap material storage component toward the unloading component. The pushing stops when the material reaches the first preset distance. Step 3: The hydraulic push assembly drives several rotary piercing components installed on it to insert into the waste material storage assembly and pierce the pre-compressed waste material. After the ends of several rotary piercing components are inserted into the pre-compressed waste material to a set depth, the radial drive assembly on several rotary piercing components drives the corresponding telescopic cutting hook assembly to extend out a set length along the radial direction of the rotary piercing component. Step 4: Reset the hydraulic push assembly. During the reset process, when the resistance of the hydraulic push assembly exceeds the preset value, the rotary puncture assembly is rotated by a set angle and / or the radial drive assembly is used to adjust the radial extension length of the telescopic cutting hook assembly along the rotary puncture assembly until the resistance of the hydraulic push assembly is lower than the preset value. Step 5: After the hydraulic pushing component is reset, the compression component pushes the initially compressed fragments to continue moving toward the unloading component. After moving to the second preset distance, the unloading component is activated, and the finished compressed block is pushed into the unloading component by the compression component. Step 6: Reset the compression component, shut down the unloading component, and repeat steps 1 to 5.

[0015] The beneficial effects of this invention are as follows: This invention uses a piercing hooking mechanism to continuously pierce the gradually formed compressed block during the process of compressing scrap into blocks. The cutting hooking component in the piercing hooking mechanism, which can control the degree of protrusion, locally cuts the metal scrap in the gaps or gaps in the compressed block and hooks the cut and broken parts towards the gaps or gaps to bend and deform. This increases the number of hooking points that can be formed inside the metal scrap during the process of compressing into blocks, thereby effectively improving the forming quality of the block and preventing it from becoming loose due to external forces during transportation.

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed merely to enable those skilled in the art to better understand and implement the subject matter described herein. Furthermore, features described in some examples may be combined in other examples.

[0019] like Figures 1 to 7 As shown, a construction waste recycling device includes: The briquetting mechanism 1 includes a material storage component, a compression component connected to one end of the material storage component, and a briquetting component connected to the other end of the material storage component. The compression component is used to push and compress the material in the material storage component toward the briquetting component and into blocks. The briquetting component is used to block and open the other end of the material storage component. Crushing mechanism 2 is fixedly installed at the upper end of the crushed material storage component. The crushing mechanism 2 is used to cut construction waste into crushed materials of a set size and discharge the crushed materials into the crushed material storage component. The piercing hook mechanism 3 includes two sets of hydraulic pushing components, several rotary piercing components mounted on the hydraulic pushing components, several telescopic cutting hook components located at the ends of the rotary piercing components, and a radial drive component installed inside the rotary piercing components. The two sets of hydraulic pushing components are staggered at the front and rear ends of the scrap accumulation component and are used to drive the several rotary piercing components to move toward or away from the scrap accumulation component. The radial drive component is used to drive the corresponding several telescopic cutting hook components to move radially along the rotary piercing component.

[0020] It should be noted that the method of recycling construction waste using the construction waste recycling device described above is specifically for the treatment of metal construction waste and includes the following steps: Step 1: A fixed amount of construction waste to be recycled is fed into the crushing mechanism 2. The crushing mechanism 2 crushes the construction waste, and the crushed material falls into the crushed material storage component. Step 2: The compression component pushes the scrap material in the scrap material storage component toward the unloading component. The pushing stops when the scrap material reaches the first preset distance. The first preset distance can be adjusted according to the actual metal material, the size and shape of the scrap material after cutting, and other parameters. Step 3: The hydraulic pusher drives several rotary piercing components mounted on it to insert into the waste material storage component and pierce the initially compressed waste material. After the ends of the rotary piercing components are inserted into the initially compressed waste material to a set depth, the radial drive components on the rotary piercing components drive the corresponding telescopic cutting hook components to extend a set length radially along the rotary piercing components. It should be noted that this method only uses one piercing process. Multiple piercing processes can also be used. The distance gap or time gap between stopping compression and piercing can be adjusted to improve the stability of the final compressed block structure. Step 4: Reset the hydraulic push assembly. During the reset process, when the resistance of the hydraulic push assembly exceeds the preset value, the rotary puncture assembly is rotated by a set angle and / or the radial drive assembly is used to adjust the radial extension length of the telescopic cutting hook assembly along the rotary puncture assembly until the resistance of the hydraulic push assembly is lower than the preset value. Step 5: After the hydraulic pushing component is reset, the compression component pushes the initially compressed fragments to continue moving toward the unloading component. After moving to the second preset distance, the unloading component is activated, and the finished compressed block is pushed into the unloading component by the compression component. Step 6: Reset the compression component, shut down the unloading component, and repeat steps 1 to 5.

[0021] In an optional embodiment of the invention, such as Figure 1 , Figure 3 and Figure 4 As shown, the scrap storage assembly includes a frame 101, a scrap storage box 102 and a collection box 107 fixedly installed on the frame 101, a plurality of circular perforations 1020 provided on the scrap storage box 102, and a connecting pipe 103 connected to the upper inlet of the scrap storage box 102. The internal space of the collection box 107 is connected to the internal space of the scrap storage box 102 through the plurality of circular perforations 1020.

[0022] The compression assembly includes a hydraulic cylinder 104 fixedly mounted on a frame 101, a compression block 105 connected to the output end of the hydraulic cylinder 104, and a horizontal blocking plate 106 fixedly connected to the upper end of the compression block 105. The length of the horizontal blocking plate 106 is greater than the stroke length of the hydraulic cylinder 104. The compression block 105 is located at one end opening of the crushed material storage box 102. When the compression block 105 moves toward the unloading assembly, the horizontal blocking plate 106 is used to block the connection between the connecting pipe 103 and the crushed material storage box 102.

[0023] The unloading assembly includes a second hydraulic cylinder 110 and a discharge box 111 fixedly mounted on a frame 101, and a vertical blocking plate 109 connected to the output end of the second hydraulic cylinder 110. The discharge box 111 is connected to the other end opening of the crushed material storage box 102. The vertical blocking plate 109 is used to block the connection between the discharge box 111 and the crushed material storage box 102. An integrated control box 108 is installed on the frame 101. The integrated control box 108 is used to control the working parameters of the first hydraulic cylinder 104, the second hydraulic cylinder 110, the crushing mechanism 2, the hydraulic pushing assembly, the rotary piercing assembly, and the radial drive assembly.

[0024] It should be noted that, as mentioned above, after a certain amount of construction waste is fed into the crushing mechanism 2 and crushed, the crushed material passes through the crushing mechanism 2 and the connecting pipe 103 in sequence before entering the crushed material storage box 102. At this time, the hydraulic cylinder 104 can drive the pressing block 105 to move towards the vertical blocking plate 109. The vertical blocking plate 109 is in a closed state. The pressing block 105 pushes the crushed material towards the vertical blocking plate 109 and gradually compresses the crushed material. The horizontal blocking plate 106 can move synchronously with the pressing block 105 and seal the connection between the connecting pipe 103 and the crushed material storage box 102. This allows the crushing mechanism 2 to continue crushing the construction waste without affecting the compression process in the crushed material storage box 102. When the pressing block 105 moves a set distance... At this point, the fragments between the compression block 105 and the vertical blocking plate 109 have been initially compressed. To increase the number of internal connection points, multiple rotary piercing components can be driven by the hydraulic push assembly to insert into the initially compressed fragments. After insertion, multiple telescopic cutting hook components are driven by the radial drive assembly on each rotary piercing component to extend from the rotary piercing component. At this point, the hydraulic push assembly is reset. During the reset process, the telescopic cutting hook components can locally cut the internal area of ​​the initially compressed fragments and bend the cut and broken area, thereby increasing the number of internal transverse deformation structures and thus increasing the number of internal connection points. When finally compressed into blocks, the connection strength between the fragments is much stronger than that of conventional compression methods.

[0025] In an optional embodiment of the invention, such as Figure 1 and Figure 2 As shown, the crushing mechanism 2 includes a U-shaped frame 201, a feed hopper 202 connected to the upper opening of the U-shaped frame 201, a plurality of fixed blades 203 fixedly connected to the inner wall of the U-shaped frame 201, a rotating shaft 204 movably connected to the U-shaped frame 201, a plurality of movable blades 205 fixedly installed on the rotating shaft 204, a synchronous pulley 206, a housing 207 fixedly connected to the U-shaped frame 201, a motor 208 fixedly installed in the housing 207, a synchronous pulley 209 connected to the output shaft end of the motor 208, and a synchronous belt 210 connecting the synchronous pulley 209 and the synchronous pulley 206. The plurality of fixed blades 203 and the plurality of movable blades 205 are distributed in an alternating manner.

[0026] It should be noted that, as mentioned above, construction waste is fed into the hopper 202, and the motor 208 drives the synchronous wheel 209 to rotate. The synchronous wheel 209 drives the synchronous wheel 206 to rotate synchronously via the synchronous belt 210. When the synchronous wheel 206 rotates, it drives the rotating shaft 204 to rotate synchronously. After the rotating shaft 204 rotates, it drives multiple movable blades 205 to rotate. When the movable blades 205 rotate, they can cut the construction waste in the hopper 202 with the fixed blades 203 that are matched with them. The crushed material falls from the gap between the movable blades 205 and the fixed blades 203 into the lower port of the U-shaped frame 201, and then falls into the crushed material storage box 102 after passing through the connecting pipe 103 for the next step of compression processing.

[0027] In an optional embodiment of the invention, such as Figure 3 and Figure 4 As shown, the hydraulic pushing assembly includes a housing 301, a movable plate 302 slidably connected to the inner wall of the housing 301, a connecting frame 303 connected to the lower end of the movable plate 302, and a hydraulic cylinder 304 fixedly connected to the frame 101. The housing 301 is fixedly connected to the frame 101, and one end of the connecting frame 303 is located outside the housing 301. A tension / compression sensor is connected between the output end of the frame 101 and the connecting frame 303. The tension / compression sensor is used to obtain the tension or thrust output by the hydraulic cylinder 304 to the connecting frame 303.

[0028] It should be noted that, as mentioned above, in order to improve the stability of the equipment, when the hydraulic push assembly pushes the rotary piercing assembly to insert into or detach from the initially compressed scrap, the tension or pressure sensor can obtain the tension or thrust applied by the hydraulic cylinder 304 to the connecting frame 303 and the moving plate 302 in real time. When the threshold is exceeded, the rotary piercing assembly can be rotated to penetrate into or detach from the scrap, so as to prevent excessive resistance from damaging the rotary piercing assembly and the telescopic cutting hook assembly on it.

[0029] In an optional embodiment of the invention, such as Figures 3 to 7 As shown, the rotary puncture assembly includes a rotary plate 305 movably connected to a movable plate 302, a drill rod 306 and a gear 307 fixedly connected to the rotary plate 305, a motor 308 fixedly connected to the movable plate 302, and a gear 309 connected to the output end of the motor 308. The drill rod 306 is fixedly connected to the end face of the rotary plate 305 near the waste material storage box 102, and the gear 307 is fixedly connected to the end face of the rotary plate 305 away from the waste material storage box 102. The gear 307 meshes with the gear 309, and the drill rod 306 is configured to cooperate with the circular puncture hole 1020.

[0030] The telescopic cutting hook assembly includes a plurality of triangular perforations 3060 evenly distributed on the drill rod 306, a telescopic rod 310 connected to the inner wall of the drill rod 306, a conical disc 311 connected to the other end of the telescopic rod 310, a connecting rod 312 fixedly connected to the central axis of the conical disc 311, a triangular pyramidal cutter body 313 fixedly connected to the other end of the connecting rod 312, and a spring 314 connected between the conical disc 311 and the inner wall of the drill rod 306. The triangular pyramidal cutter body 313 is configured to cooperate with the triangular perforations 3060.

[0031] The radial drive assembly includes a threaded tube 315 slidably connected to the inner wall of the drill pipe 306, a truncated cone 316 fixedly connected to one end of the threaded tube 315, a screw 317 movably connected to the central axis of the rotating plate 305, and a motor 318 fixedly mounted on the rotating plate 305. The output shaft end of the motor 318 is connected to one end of the screw 317. The screw 317 is threadedly connected to the threaded tube 315. The truncated cone 316 is configured to cooperate with the cone disc 311.

[0032] It should be noted that, as described above, when the moving plate 302 moves toward the scrap storage box 102, it can drive the rotating plate 305 connected to it and the drill rod 306 fixedly connected to the rotating plate 305 to move synchronously, so that the drill rod 306 passes through the corresponding circular through hole 1020 and is inserted into the initially compressed scrap. When the drill rod 306 reaches the set insertion depth, the screw 317 drives the truncated cone 316 to rotate. The truncated cone 316 can drive the threaded tube 315, which is threaded to it and slidably connected to the drill rod 306, to move toward the tip area of ​​the drill rod 306, and drive the truncated cone 316 connected to it to move synchronously. The truncated cone 316 moves toward the tip area of ​​the drill rod 306. During this process, the cone discs 311 that are in contact with the drill rod 306 can be continuously and stably squeezed to move outward along the radial direction of the drill rod 306. When moving, the connecting rod 312 connected to it and the triangular pyramidal cutter body 313 connected to the connecting rod 312 can move synchronously and compress the telescopic rod 310 and the spring 314. The triangular pyramidal cutter body 313 extends a set distance from the triangular through hole 3060. The tip of the triangular pyramidal cutter body 313 is inserted into the scrap, and its cutting edge conforms to the moving path of the drill rod 306 when it is withdrawing the scrap. In this process, the scrap is continuously cut. The broken gaps generated by the cutting on the scrap will be compressed and bent by the expansion mechanism that the triangular pyramidal cutter body 313 passes through, thereby creating new connection points between the scrap. If there is a travel obstruction, the second motor 308 can drive the second gear 309 to rotate. When the second gear 309 rotates, it can drive the first gear 307, which meshes with it, to rotate synchronously. After the first gear 307 rotates, it can drive the rotating plate 305 to rotate synchronously. Since the third motor 318, screw 317, threaded tube 315 and other structures are all integrated on the rotating plate 305, during the process of the rotating plate 305 driving the drill rod 306 to rotate, the threaded tube 315 can be adjusted to move along the axial direction of the drill rod 306. This allows the length of the triangular pyramidal cutter body 313 extending out of the triangular through hole 3060 to be adjusted synchronously during the rotation of the drill rod 306. This is to adapt to the adjustment of the travel resistance when the drill rod 306 inserts into or detaches from the crushed material, and to increase the diversity of the cutting and crushing area distribution.

[0033] The above description of this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.

10. A method for recycling construction waste, characterized in that, The construction waste recycling device according to any one of claims 1-9 includes the following steps: Step 1: The amount of construction waste to be recycled is put into the crushing mechanism (2). The crushing mechanism (2) crushes the construction waste, and the crushed material falls into the crushed material storage component. Step 2: The compression component pushes the scrap material in the scrap material storage component toward the unloading component. The pushing stops when the material reaches the first preset distance. Step 3: The hydraulic push assembly drives several rotary piercing components installed on it to insert into the waste material storage assembly and pierce the pre-compressed waste material. After the ends of several rotary piercing components are inserted into the pre-compressed waste material to a set depth, the radial drive assembly on several rotary piercing components drives the corresponding telescopic cutting hook assembly to extend out a set length along the radial direction of the rotary piercing component. Step 4: Reset the hydraulic push assembly. During the reset process, when the resistance of the hydraulic push assembly exceeds the preset value, the rotary puncture assembly is rotated by a set angle and / or the radial drive assembly is used to adjust the radial extension length of the telescopic cutting hook assembly along the rotary puncture assembly until the resistance of the hydraulic push assembly is lower than the preset value. Step 5: After the hydraulic pushing component is reset, the compression component pushes the initially compressed fragments to continue moving toward the unloading component. After moving to the second preset distance, the unloading component is activated, and the finished compressed block is pushed into the unloading component by the compression component. Step 6: Reset the compression component, shut down the unloading component, and repeat steps 1 to 5.
