Description

Technical Field

[0001] The present invention relates to the technical field of boiler recycling, and specifically to a waste boiler recycling and crushing device. Background Art

[0002] In today's society, the importance of environmental protection and resource recycling has become increasingly prominent, and the recycling and treatment of waste boilers have become a key issue that needs to be solved urgently. The metal components of these boilers are complex and usually contain multiple elements such as iron, aluminum, and copper. In the past, the traditional methods for dealing with waste boilers mostly relied on simple means such as manual disassembly or mechanical crushing. However, this method is not only inefficient but also has significant deficiencies in ensuring the consistency of the fragment sizes, which undoubtedly adds great challenges and inconveniences to the subsequent classification and recycling processes.

[0003] In response to the above problems, although some waste boiler treatment devices with relatively high automation levels have emerged in the prior art, these devices still have deficiencies in terms of treatment efficiency and fragment size control. For example, some devices have a crushing function but lack an efficient fragment classification and recycling mechanism, resulting in inconsistent fragment sizes after treatment, increasing the difficulty and cost of subsequent treatment.

[0004] Based on this, a waste boiler recycling and crushing device is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0005] The purpose of the present invention is to provide a waste boiler recycling and crushing device to solve the problem that some devices in the background art have a crushing function but the fragment sizes after treatment are inconsistent, increasing the difficulty and cost of subsequent treatment.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A waste boiler recycling and crushing device includes a crushing box. A feeding hopper is fixed at the upper end of the crushing box. Inside the crushing box, a crushing structure, a recycling structure, an adsorption structure, and a discharging structure are sequentially arranged from top to bottom. A guiding inclined plate is fixed on the left inner wall of the crushing box, and the guiding inclined plate is located below the adsorption structure. Discharge ports one and two are symmetrically opened on the left and right sides of the bottom inside the crushing box respectively. A triangular material distributing plate is fixed at the middle position of the bottom inside the crushing box. A blower is installed on the left side of the crushing box, and the air outlet of the blower is located between the guiding inclined plate and the triangular material distributing plate.

[0008] Preferably, the crushing structure includes a first crushing roller and a second crushing roller which are rotatably installed at the top inside the crushing box and cooperate with each other. A first motor is installed at the front end of the crushing box, and the output end of the first motor extends into the crushing box and is fixedly connected to the first crushing roller. The other end of the first crushing roller extends to the rear end of the crushing box and is fixedly connected to a first gear. The front and rear ends of the second crushing roller penetrate through the crushing box and are respectively fixedly connected to a first driving wheel and a second gear. The first gear meshes with the second gear, and the first driving wheel is connected to the recycling structure through a first transmission belt.

[0009] Preferably, the recycling structure includes a second driving wheel rotatably installed at the front end of the crushing box. The second driving wheel is connected to the first driving wheel through a first transmission belt. A third driving wheel is fixed at the end of the second driving wheel away from the crushing box. The third driving wheel is connected to the adsorption structure through a second transmission belt. The other end of the second driving wheel extends into the crushing box and is fixedly connected to a first auger. The first auger is rotatably installed at the upper end of the converging arc plate and inside the first conveying cylinder. The converging arc plate is installed inside the crushing box, and a number of filter holes are penetrated through the converging arc plate. Two converging inclined plates are symmetrically installed inside the crushing box. The lowest ends of the two converging inclined plates are respectively fixed to both ends of the converging arc plate. The first conveying cylinder is fixed at the rear end of the crushing box. The first conveying cylinder is connected to the second conveying cylinder through a first inclined pipe. The second conveying cylinder is fixed at the upper end of a fixing plate, and the fixing plate is fixed at the rear end of the crushing box. A second motor is installed at the top end of the second conveying cylinder. The output end of the second motor extends into the second conveying cylinder and is fixedly connected to a second auger. An inclined pipe two is fixed at the top end of the side wall of the second conveying cylinder, and the discharging port of the inclined pipe two faces the feed hopper.

[0010] Preferably, the adsorption structure includes a magnetic roller rotatably installed inside the crushing box. A scraping block for scraping the iron metal adsorbed by the magnetic roller is fixed on the right side inside the crushing box. The front end of the magnetic roller penetrates to the front end of the crushing box and is fixedly connected to a third gear. The third gear is connected to the discharging structure, and a fourth driving wheel is fixed at the front end of the third gear. The fourth driving wheel is connected to the third driving wheel through a second transmission belt.

[0011] Preferably, a discharging inclined plate is fixed at the right end of the crushing box, and a third discharging port is opened at the connection between the crushing box and the discharging inclined plate. The discharging structure includes a fourth gear rotatably installed at the front end of the crushing box. The fourth gear is meshed with the third gear. One end of the fourth gear extends into the crushing box and is fixedly connected to a driving roller. A driven roller is rotatably installed inside the crushing box at the position of the third discharging port and cooperates with the driving roller. A conveyor belt is sleeved on the outer walls of the driving roller and the driven roller.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The present invention combines a crushing structure, a recycling structure, a converging inclined plate, and a converging arc plate. The crushing structure crushes the waste boiler into fragments. The crushed fragments are gathered onto the converging arc plate through the two converging inclined plates. Smaller fragments can fall through a number of filter holes opened on the converging arc plate for subsequent operations. Larger fragments are sent back to the feed hopper by the recycling structure on the converging arc plate, and the larger fragments are crushed again by the crushing structure to ensure that all fragments meet the predetermined size requirements for subsequent classification and recycling.

[0014] 2. The present invention combines an adsorption structure, a scraping block, and a discharging structure. When the fragments pass through the magnetic roller of the adsorption structure, the magnetic roller adsorbs the iron metal in the fragments and brings it to the position of the scraping block 105. The scraping block scrapes the iron metal on the surface of the magnetic roller to achieve the separation of the iron metal. The separated iron metal naturally falls onto the upper surface of the conveyor belt under the action of gravity. The fourth gear rotates driven by the third gear, and then drives the driving roller to rotate. The rotation of the driving roller drives the conveyor belt to move through friction, gradually conveying the iron metal to the position of the third discharge port. The iron metal is discharged from the crushing box and slides onto the discharge inclined plate to complete the recycling of the iron metal. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, as Figures 1 - 5 shown, a waste boiler recycling and crushing device includes a crushing box 1. A feeding hopper 11 is fixed at the upper end of the crushing box 1. A crushing structure 2, a recycling structure 3, an adsorption structure 4 and a discharge structure 5 are sequentially arranged in the crushing box 1 from top to bottom. A guide inclined plate 103 is fixed on the left inner wall of the crushing box 1. The guide inclined plate 103 is located below the adsorption structure 4. First discharge port 13 and second discharge port 14 are symmetrically formed on the left and right sides of the bottom inside the crushing box 1 respectively. A triangular material distribution plate 104 is fixed at the middle position of the bottom inside the crushing box 1. A blower 6 is installed on the left side of the crushing box 1. The air outlet of the blower 6 is located between the guide inclined plate 103 and the triangular material distribution plate 104.

[0023] In this embodiment, first, the extruded waste boiler is placed into the feeding hopper 11. The waste boiler enters the inside of the crushing box 1 through the feeding hopper 11. Next, the waste boiler is crushed into pieces by the crushing structure 2. Larger pieces will be re-fed into the feeding hopper 11 by the recycling structure 3 for secondary crushing to ensure that the boiler is completely crushed.

[0024] When the remaining pieces come into contact with the adsorption structure 4, the iron metal in the pieces will be adsorbed by the adsorption structure 4, and the adsorbed iron metal will then be discharged through the discharge structure 5.

[0025] When the remaining fragments fall to the triangular material distribution plate 104 through the guide inclined plate 103, these fragments have been initially crushed by the crushing structure 2 and secondarily processed by the recovery structure 3 (for larger fragments), and have also been separated from the iron metal by the adsorption structure 4. At this stage, the fragments are relatively small and the iron metal has been effectively removed.

[0026] When the fragments slide down from the guide inclined plate 103, the airflow generated by the blower 6 will blow the fragments. Since aluminum has a low density and is highly sensitive to airflow, it will be blown away from the mainstream direction. The blown aluminum fragments are eventually discharged through the second discharge port 14 for recycling. Copper with a higher density will fall directly and eventually be discharged through the first discharge port 13 for recycling.

[0027] In an optional embodiment, the crushing structure 2 includes two crushing rollers 1 202 and 205 which are rotatably installed on the top of the crushing box 1 and used in conjunction with each other. A motor 201 is installed at the front end of the crushing box 1. The output end of the motor 201 extends to the inside of the crushing box 1 and is fixedly connected to the crushing roller 202. The other end of the crushing roller 202 extends to the rear end of the crushing box 1 and is fixedly connected to the gear 1 203. The front and rear ends of the crushing roller 2 205 both pass through the crushing box 1 and are respectively fixedly connected to the transmission wheel 1 206 and the gear 2 204. The gear 1 203 is meshed with the gear 2 204. The transmission wheel 1 206 is connected to the recovery structure 3 through a transmission belt 1 207.

[0028] It should be noted that when the motor 1 201 is started, it drives the crushing roller 1 202 to rotate. Due to the meshing relationship between the gear 1 203 and the gear 2 204, the crushing roller 2 205 will also rotate synchronously. The rotation of the two crushing rollers will generate strong squeezing and shearing forces, thereby crushing the waste boiler entering the crushing box 1 into smaller fragments. At the same time, due to the connection between the transmission wheel 1 206 and the transmission belt 1 207, the larger fragments among these fragments will be sent back to the crushing structure 2 by the recycling structure 3 for secondary crushing to ensure that the size of the fragments meets the requirements.

[0029] In an alternative embodiment, the recycling structure 3 includes a second driving wheel 301 rotatably mounted at the front end of the crushing box 1. The second driving wheel 301 is drivingly connected to the first driving wheel 206 through a first transmission belt 207. A third driving wheel 302 is fixed to the end of the second driving wheel 301 away from the crushing box 1. The third driving wheel 302 is drivingly connected to the adsorption structure 4 through a second transmission belt 303. The other end of the second driving wheel 301 extends into the crushing box 1 and is fixedly connected to a first auger 304. The first auger 304 is rotatably mounted at the upper end of the converging arc plate 102 and inside the first conveying cylinder 305. The converging arc plate 102 is installed inside the crushing box 1. A plurality of filter holes 1021 are formed through the converging arc plate 102. Two converging inclined plates 101 are symmetrically installed inside the crushing box 1. The lowest ends of the two converging inclined plates 101 are respectively fixed to both ends of the converging arc plate 102. The first conveying cylinder 305 is fixed to the rear end of the crushing box 1. The first conveying cylinder 305 is communicated with a second conveying cylinder 310 through a first inclined pipe 306. The second conveying cylinder 310 is fixed to the upper end of a fixing plate 15. The fixing plate 15 is fixed to the rear end of the crushing box 1. A second motor 312 is installed at the top end of the second conveying cylinder 310. The output end of the second motor 312 extends into the second conveying cylinder 310 and is fixedly connected to a second auger 311. An inclined pipe 313 is fixed to the top end of the side wall of the second conveying cylinder 310. The discharge port of the inclined pipe 313 faces the feed hopper 11.

[0030] It should be noted that when the crushing structure 2 is working, the generated fragments will fall onto the converging inclined plates 101. Under the guidance of the converging inclined plates 101, the fragments will flow towards the converging arc plate 102. On the converging arc plate 102, the smaller fragments will fall through the filter holes 1021, while the larger fragments will be collected by the first auger 304 and conveyed into the first conveying cylinder 305. Then, these larger fragments will enter the second conveying cylinder 310 through the first inclined pipe 306. In the second conveying cylinder 310, the second motor 312 drives the second auger 311 to rotate, further conveying the fragments and sending them back to the feed hopper 11 through the inclined pipe 313 for secondary crushing.

[0031] In an alternative embodiment, the adsorption structure 4 includes a magnetic roller 403 rotatably mounted inside the crushing box 1. A scraping block 105 for scraping the iron metals adsorbed by the magnetic roller 403 is fixed to the right side inside the crushing box 1. The front end of the magnetic roller 403 penetrates through the front end of the crushing box 1 and is fixedly connected to a third gear 402. The third gear 402 is connected to the discharging structure 5. A fourth driving wheel 401 is fixed to the front end of the third gear 402. The fourth driving wheel 401 is drivingly connected to the third driving wheel 302 through a second transmission belt 303.

[0032] It should be noted that the magnetic roller 403 starts to rotate driven by the second conveyor belt 303. Since the surface of the magnetic roller 403 has magnetism, it will adsorb the iron metals in the debris. As the magnetic roller 403 continues to rotate, these adsorbed iron metals will be brought to the position of the scraping block 105. When the magnetic roller 403 contacts the scraping block 105, the scraping block 105 will scrape off the iron metals on the surface of the magnetic roller 403, thus realizing the separation of the iron metals.

[0033] In an alternative embodiment, a discharge inclined plate 12 is fixed to the right end of the crushing box 1. A third discharge port is provided at the connection between the crushing box 1 and the discharge inclined plate 12. The discharge structure 5 includes a fourth gear 501 rotatably installed at the front end of the crushing box 1. The fourth gear 501 is meshed and connected with the third gear 402. One end of the fourth gear 501 extends into the crushing box 1 and is fixedly connected to a driving roller 502. A driving roller 502 is rotatably installed inside the crushing box 1. A driven roller 504 cooperating with the driving roller 502 is rotatably installed at the position of the third discharge port. A conveyor belt 503 is sleeved on the outer walls of the driving roller 502 and the driven roller 504.

[0034] It should be noted that after the magnetic roller 403 in the adsorption structure 4 separates the iron metals from the debris, the iron metals naturally fall onto the upper surface of the conveyor belt 503 under the action of gravity. At the same time, the discharge structure 5 operates. The fourth gear 501 rotates driven by the third gear 402, and then drives the driving roller 502 to rotate. The rotation of the driving roller 502 drives the conveyor belt 503 to move through friction. As the conveyor belt 503 moves, the iron metals are gradually conveyed to the position of the third discharge port and finally discharged from the crushing box 1 and slide onto the discharge inclined plate 12.

[0035] The above embodiment discloses a waste boiler recycling and crushing device. Among them, the waste boiler is first placed in the feed hopper 11. The device is started and the first motor 201 starts to work.

[0036] The first motor 201 drives the first crushing roller 202 to rotate. Due to the meshing relationship between the first gear 203 and the second gear 204, the second crushing roller 205 also rotates synchronously. The waste boiler is squeezed and sheared by the two cooperating first crushing roller 202 and second crushing roller 205, and thus is crushed into smaller debris.

[0037] The crushed debris falls on the converging inclined plate 101 and then flows to the converging arc plate 102. The smaller debris falls through the filter holes 1021 on the converging arc plate 102, while the larger debris is collected by the first auger 304. The first auger 304 conveys the larger debris into the first conveying cylinder 305 and then enters the second conveying cylinder 310 through the first inclined pipe 306. In the second conveying cylinder 310, the second motor 312 drives the second auger 311 to rotate, further conveys the debris and sends it back to the feed hopper 11 through the second inclined pipe 313 for secondary crushing.

[0038] Meanwhile, the magnetic roller 403 starts to rotate driven by the second conveyor belt 303. The magnetic roller 403 adsorbs the iron metal in the debris and brings it to the position of the scraping block 105. The scraping block 105 scrapes the iron metal on the surface of the magnetic roller 403 to achieve the separation of the iron metal.

[0039] The separated iron metal naturally falls onto the upper surface of the conveyor belt 503 under the action of gravity. The fourth gear 501 rotates driven by the third gear 402, and then drives the driving roller 502 to rotate. The rotation of the driving roller 502 drives the conveyor belt 503 to move through friction, gradually conveying the iron metal to the position of the third discharge port. The iron metal is discharged from the crushing box 1 and slides onto the discharge inclined plate 12 to complete the recovery of the iron metal.

[0040] The remaining debris (mainly aluminum and copper) after being crushed, recovered, and having the iron metal adsorbed falls on the triangular material distribution plate 104. When the debris slides down from the guiding inclined plate 103, the air flow generated by the hair dryer 6 blows the debris. Since the density of aluminum is relatively small and its sensitivity to the air flow is relatively high, it will be blown away from the main flow direction and discharged through the second discharge port 14 for recovery. The copper with a relatively large density will directly fall and be discharged through the first discharge port 13 for recovery.

[0041] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
