Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, and in particular to a resource-based treatment device for garden engineering waste. Background Technology

[0002] With the continuous development of urban greening and landscaping projects, a large amount of landscaping project waste is generated every year. This waste mainly includes pruned branches, leaves, grass clippings, roots, and soil.

[0003] To achieve sustainable development and environmental protection, the recycling of these landscaping project wastes, such as processing them into organic fertilizers, landscaping, or biomass fuels, has become a major trend in the industry. This usually requires the use of specialized processing equipment to crush and reduce the volume of the waste. However, during the construction and maintenance of landscaping projects, various impurities, especially metallic debris such as nails, wires, and packaging sheet metal, inevitably get mixed into the waste.

[0004] Most existing garden waste treatment devices only have crushing functions. When these wastes mixed with metal debris are crushed together, metal fragments remain in the final organic material. This not only seriously affects the quality of subsequent fermentation and fertilizer production or the safety of use as a mulch, but may also damage subsequent processing equipment, resulting in a significant reduction in the overall effect of resource utilization and making it impossible to achieve efficient and high-quality resource utilization.

[0005] Therefore, this utility model proposes a resource-based treatment device for garden engineering waste to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problem that existing garden engineering waste resource recovery devices have limited functionality and cannot automatically separate mixed metal substances while crushing materials, resulting in low purity of the final organic debris, this utility model aims to provide a garden engineering waste resource recovery device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a resource utilization device for garden engineering waste, including a primary crushing component, a secondary crushing component, and a conveying component. The conveying component includes a first conveyor belt. The device also includes a magnetic separation component.

[0008] The magnetic separation assembly includes a mounting frame, a second conveyor belt, a magnet, a drive motor, and a material channel. The second conveyor belt is rotatably connected to the mounting frame, the magnet is fixed in the internal space of the second conveyor belt, the drive motor is connected to the second conveyor belt, and the material channel is fixed on the mounting frame.

[0009] Furthermore, the secondary crushing component is fixedly connected below the primary crushing component, the conveying component is located below the secondary crushing component, and the mounting frame of the magnetic separation component is fixed above the frame of the conveying component, with its second conveyor belt located above the discharge end of the first conveyor belt. Through this integrated upstream and downstream structural layout, automatic identification and separation of metallic substances are achieved on the material conveying path.

[0010] Preferably, the internal structure of the preliminary crushing assembly is further defined, including a feed hopper and a biaxial crushing roller rotatably disposed below the feed hopper, as well as a first motor and gear set for driving the biaxial crushing roller to rotate, and a support column for stably supporting the entire feed hopper. This structural design ensures stable and efficient preliminary crushing of large materials.

[0011] Preferably, the internal structure of the secondary crushing component is also refined, including a shell and a mesh cylinder fixedly installed inside the shell. The hammer crushing shaft passes through the inside of the mesh cylinder and is rotatably connected to the shell. The second motor is driven and connected to the hammer crushing shaft. This design can further crush the material after primary crushing and control the output particle size through the mesh cylinder.

[0012] Preferably, the conveying assembly has a more complete structure, including a third motor that is driven to the first conveyor belt, a first baffle fixed to both sides of the first conveyor belt along its length, and legs for stable support of the entire conveying assembly. These additional structures ensure the stability and continuity of material conveying and effectively prevent material from spilling during the conveying process.

[0013] Preferably, in order to improve the separation efficiency of metal substances, multiple second baffles are fixedly connected to the outer surface of the second conveyor belt. These second baffles rotate synchronously with the second conveyor belt and can actively scrape off the adsorbed metal substances and guide them to the material channel, thereby enhancing the reliability of separation.

[0014] Preferably, the discharge port of the primary crushing component is vertically aligned with and connected to the feed port of the secondary crushing component. This direct connection optimizes the material transfer path from primary crushing to secondary crushing, making the entire crushing process smoother and avoiding material blockage.

[0015] Preferably, the garden engineering waste resource utilization device further includes a collection box, which is located below the material channel to collect and store the metal material discharged from the material channel, facilitating the unified processing of the recycled metal in the future.

[0016] Preferably, the end of the first conveyor belt not covered by the second conveyor belt constitutes an organic material outlet for discharging non-metallic debris. The pure organic debris material after magnetic separation is discharged from this outlet, clarifying the separation path of the two materials and making the collection and processing of the final product more convenient.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that after garden waste is crushed, metal impurities cannot be automatically separated, resulting in low purity of the final organic debris and failure to recover metals, by setting a magnetic separation component above the conveying component. The magnetic separation component includes a second conveyor belt with built-in magnets, a drive motor, and a material channel. It realizes integrated processing of material crushing, conveying, automatic metal separation and collection in a single device, improves the purity and quality of organic debris, and realizes the recycling of metal resources.

[0018] 2. This utility model solves the problems of discontinuous waste treatment processes, the need for multiple devices or manual intervention for sorting, and low processing efficiency and low degree of automation in the prior art by integrating the primary crushing component, secondary crushing component, conveying component and magnetic separation component into an integrated, assembly-line structure. It achieves the technical effect of compact equipment structure, automated process and efficient and continuous processing, effectively reducing labor costs and equipment footprint.

[0019] 3. This utility model, through a two-stage crushing design using a dual-shaft crushing roller for initial crushing and a hammer crushing shaft for secondary fine crushing, achieves the technical effect of thorough crushing of various wastes, strong adaptability, and uniform and controllable output particle size, creating favorable conditions for subsequent smooth conveying and efficient magnetic separation.

[0023] Please refer to Figures 1 to 5 This utility model provides a resource recovery device for garden engineering waste, which aims to solve the problem that existing garden engineering waste treatment devices can only crush but cannot automatically separate metal impurities in the process, resulting in low purity of the final organic debris and the failure to recover metals.

Figure 1 and Figure 3 As shown, the magnetic separation assembly 4 includes a mounting frame 401 fixed above the frame of the conveying assembly 3. The magnetic separation assembly 4 also includes a second conveyor belt 403 rotatably connected to the mounting frame 401. The second conveyor belt 403 is located above the discharge end of the first conveyor belt 301. The magnet 402 is fixed in the internal space of the second conveyor belt 403. The magnetic separation assembly 4 also includes a drive motor 405 that is drively connected to the second conveyor belt 403, and a material channel 406 fixed on the mounting frame 401 and extending from one side of the second conveyor belt 403.

[0025] To address the aforementioned technical problems and achieve effective treatment and separation of waste, this embodiment provides specific limitations on the structure for realizing the crushing and conveying functions. Please refer to the following for details. Figure 4 The preliminary crushing assembly 1 includes a feed hopper 101 through which material enters the device. A dual-shaft crushing roller 102 is rotatably arranged below the feed hopper 101. The preliminary crushing assembly 1 also includes a first motor 104 and a gear set 103 for driving the dual-shaft crushing roller 102 to rotate. The gear set 103 is connected between the output shaft of the first motor 104 and the dual-shaft crushing roller 102. The preliminary crushing assembly 1 also includes a support column 105 for supporting the feed hopper 101.

[0026] Please refer to the following carefully. Figure 5 The secondary crushing component 2 is fixedly connected below the primary crushing component 1. Specifically, the discharge port of the primary crushing component 1 is vertically aligned with and connected to the inlet of the secondary crushing component 2. The secondary crushing component 2 includes a housing 202 and a mesh cylinder 203 fixedly installed inside the housing 202. The hammer crushing shaft 204 passes through the mesh cylinder 203 and is rotatably connected to the housing 202. The secondary crushing component 2 also includes a second motor 201 that is driven to the hammer crushing shaft 204. The second motor 201 drives the hammer crushing shaft 204 to rotate at high speed inside the mesh cylinder 203.

[0027] Please refer to the following carefully. Figure 2 The conveying component 3 is located below the secondary crushing component 2 and is used to receive the debris discharged from the mesh cylinder 203. The conveying component 3 includes a first conveyor belt 301 rotatably mounted on the frame. The conveying component 3 also includes a third motor 303 drivenly connected to the first conveyor belt 301 and support legs 304 for supporting the conveying component 3. First baffles 302 are fixedly connected to both sides of the first conveyor belt 301 along its length.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 1 and Figure 3 In order to more effectively scrape off the metal material adsorbed on the surface of the second conveyor belt 403 and convey it to the material channel 406, a plurality of second baffles 404 are fixedly connected to the outer surface of the second conveyor belt 403. The second baffles 404 move synchronously with the rotation of the second conveyor belt 403, forcibly carrying the adsorbed metal material away from the magnetic field area and guiding it to the material channel 406.

[0029] As another preferred embodiment, please refer to Figure 1 In order to centrally recover the separated metal material, the device also includes a collection box 5, which is detachably installed below the material channel 406 to receive and store the metal material falling from the material channel 406.

[0030] As another preferred embodiment, please refer to Figure 1 The end of the first conveyor belt 301 that is not covered by the second conveyor belt 403 naturally forms an organic material outlet for discharging non-metallic debris. After magnetic separation, the organic debris material that does not contain metal impurities will be discharged from the organic material outlet as the first conveyor belt 301 continues to run, so as to facilitate subsequent collection and resource utilization.

[0031] The working principle of this utility model's garden engineering waste resource utilization device is as follows: When garden waste is fed into the feed hopper 101 of the primary crushing component 1, the feed hopper 101, supported by the support column 105, guides the material to the dual-shaft crushing roller 102. The first motor 104 drives the dual-shaft crushing roller 102 to rotate through the gear set 103, performing preliminary shearing and crushing on the material. The material after primary crushing falls into the secondary crushing component 2 under the action of gravity. The material enters the mesh cylinder 203 fixed inside the shell 202. The second motor 201 drives the hammer crushing shaft 204, which passes through the mesh cylinder 203, to rotate at high speed. The hammers on the hammer crushing shaft 204 powerfully strike and tear the material. The fragments that meet the size requirements pass through the holes on the mesh cylinder 203 and are discharged from the bottom of the shell 202.

[0032] The discharged debris falls onto the first conveyor belt 301 of the conveying assembly 3, which is supported by legs 304. The third motor 303 drives the first conveyor belt 301 to rotate, conveying the debris forward. The first baffles 302 on both sides of the first conveyor belt 301 prevent the debris from falling. When the debris moves with the first conveyor belt 301 to below the magnetic separator 4, the magnetic separator 4 located above the discharge end of the first conveyor belt 301 starts to work. The magnet 402 fixed in the internal space of the second conveyor belt 403 generates a magnetic field, which attracts the metal substances mixed in the debris to the outer surface of the second conveyor belt 403. The drive motor 405 is connected to the second conveyor belt 403 and drives the second conveyor belt 403 to rotate around the mounting frame 401. The second baffle 404 on the outer surface of the second conveyor belt 403 assists in moving these metal substances. When the metal substances leave the magnetic field range of the magnet 402 as the second conveyor belt 403 rotates, they fall off under the action of gravity and fall into the material channel 406 fixed on the mounting frame 401.

[0033] Metallic materials slide down the feed channel 406 and eventually enter the collection box 5 located below the feed channel 406, realizing the automatic separation and collection of metallic impurities. Meanwhile, organic debris materials without metals continue to move along the first conveyor belt 301 and are eventually discharged from the organic material outlet for subsequent resource utilization.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
