Description

Technical Field

[0001] This invention relates to the field of iron scrap recycling technology, specifically to an iron scrap recycling briquetting machine. Background Technology

[0002] In industries such as machining, automotive parts manufacturing, and machine tool processing, metal cutting processes generate a large amount of waste such as iron filings, steel filings, and shavings. Directly discarding this waste not only occupies space and pollutes the environment but also wastes valuable metal resources. By recycling and briquetting, loose, oily, and water-containing iron filings can be compressed into high-density blocks, facilitating transportation, storage, and remelting, significantly reducing logistics costs and improving metal recovery rates.

[0003] Traditional briquetting machines typically use a fixed base plate or a manual insert plate at the bottom of the hopper. After briquetting, the baffle plate must be manually removed or the hopper door opened to take out the briquetting blocks. This operation is cumbersome and inefficient. Furthermore, a small amount of coolant will remain in the iron filings. During compression, the coolant will overflow and is usually not collected properly. Coolant can be recycled and reused through processing. Therefore, not collecting the overflowing coolant will result in waste and pollute the working environment.

[0004] Therefore, a scrap metal recycling briquetting machine is proposed to solve the problems mentioned above. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a scrap metal recycling briquetting machine. This solves the problem that traditional briquetting machines often use fixed base plates or manual inserts at the bottom of the hopper. After briquetting, manual removal of the baffle or opening of the hopper door is required to remove the briquetting blocks, which is cumbersome and inefficient. Furthermore, a small amount of coolant remains in the scrap metal, overflowing during compression. This coolant is often not properly collected, and since it can be recycled and reused, the overflowing coolant is wasted and pollutes the working environment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a desktop, the top of which is provided with a switching mechanism, the switching mechanism including a hopper, a fixing groove, a guide hole, a cylinder, a first baffle, a guide rod, a through groove, an overflow hole and an arc groove; The hopper is fixedly connected to the top of the tabletop, the fixing groove is opened at the bottom of the hopper, the guide hole is opened inside the hopper, the cylinder is fixedly connected to the bottom of the tabletop, the first baffle is fixedly connected to the output end of the cylinder, the guide rod is fixedly connected to the top of the first baffle, the through groove is opened at the top of the tabletop, the overflow hole is opened on the outside of the first baffle, and the arc-shaped groove is opened on the top side of the tabletop.

[0015] Compared with the prior art, the present invention provides a scrap metal recycling briquetting machine, which has the following beneficial effects: 1. The first hydraulic cylinder presses down the iron filings to compress them into block-shaped materials. The second hydraulic cylinder pushes the block-shaped iron filings out of the hopper, thus achieving automatic compression and automatic feeding. The operation is more convenient.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: Please see Figure 1 - Figure 7The scrap metal recycling briquetting machine in this embodiment includes a desktop 1, and a switching mechanism is provided on the top of the desktop 1. The switching mechanism includes a hopper 2, a fixing groove 3, a guide hole 4, a cylinder 5, a first baffle 6, a guide rod 7, a through groove 8, an overflow hole 9, and an arc groove 10. The hopper 2 is fixedly connected to the top of the tabletop 1, the fixing groove 3 is opened at the bottom of the hopper 2, the guide hole 4 is opened inside the hopper 2, the cylinder 5 is fixedly connected to the bottom of the tabletop 1, the first baffle 6 is fixedly connected to the output end of the cylinder 5, the guide rod 7 is fixedly connected to the top of the first baffle 6, the through groove 8 is opened at the top of the tabletop 1, the overflow hole 9 is opened on the outside of the first baffle 6, and the arc groove 10 is opened on the top side of the tabletop 1.

[0022] In use, iron filings are placed inside the hopper 2. The first hydraulic cylinder 22 presses down on the iron filings to compress them into block-shaped materials. At this time, the cylinder 5 pulls the first baffle 6, which disengages from the fixed groove 3 and slides into the through groove 8. At this time, the top of the first baffle 6 is flush with the top of the table 1. Then, the second hydraulic cylinder 23 pushes the block-shaped iron filings out of the hopper 2, thereby achieving the effects of automatic compression into blocks and automatic feeding, making operation more convenient. During the extrusion process, the coolant on the surface of the iron filings will be squeezed out from the overflow hole 9 and guided through the arc groove 10 for easy subsequent collection. Wear-resistant liners can be added to the inner wall of the hopper 2, using high-chromium cast iron or welded wear-resistant alloy layers to resist the scraping and wear of the iron filings under high pressure and extend the service life of the hopper 2. Flexible sealing strips can be laid in the fixed groove 3 to form an initial seal when the first baffle 6 is closed, reducing the leakage of coolant from the gaps during the initial extrusion.

[0023] Please see Figure 1 - Figure 7 The first baffle 6 is slidably connected inside the through groove 8. The inner wall of the through groove 8 is in contact with the outer wall of the first baffle 6. The outer wall of the first baffle 6 is in contact with the inner wall of the fixing groove 3. The guide rod 7 is slidably connected inside the guide hole 4.

[0024] To facilitate material unloading, a material unloading mechanism is provided on one side of the tabletop 1. The material unloading mechanism includes a guide frame 11, a second baffle 12, an inclined surface 14, a groove 15, and a liquid outlet pipe 16. The guide frame 11 is fixedly connected to one side of the tabletop 1, the second baffle 12 is fixedly connected to the end of the guide frame 11, the inclined surface 14 is provided inside the guide frame 11, the groove 15 is opened inside the guide frame 11, and the liquid outlet pipe 16 is fixedly connected to the bottom of the guide frame 11.

[0025] The second hydraulic cylinder 23 pushes the blocky iron filings out of the hopper 2. At this time, the blocky iron filings automatically slide down through the inclined plane 14 and fall into the collection box for collection and storage, thereby achieving the effect of automatic collection. Furthermore, the inclined plane 14 can reduce the occurrence of scattering of the blocky iron filings after they fall. The guard plate can guide the material and reduce the occurrence of falling from the side.

[0026] Please see Figure 1 - Figure 7 The guide rack 11 has a protective plate on its side and a storage box at the bottom of one end of the guide rack 11.

[0027] To facilitate the collection of coolant, a receiving mechanism is provided at the bottom of the tabletop 1. The receiving mechanism includes a fixed frame 17, a positioning groove 18, a collection bottle 19, and a hopper 20. The fixed frame 17 is fixedly connected to one side of the bottom of the tabletop 1, the positioning groove 18 is opened on one side of the fixed frame 17, the collection bottle 19 is placed inside the positioning groove 18, and the hopper 20 is fixedly connected to the inside of the fixed frame 17.

[0028] The coolant guided by the arc groove 10 flows into the groove 15 and is discharged through the outlet pipe 16 inside the groove 15. The discharged coolant is guided through the hopper 20 and collected and stored in the collection bottle 19. This setting can prevent the coolant from spilling. The collection bottle 19 is positioned by the positioning groove 18, which can achieve better collection effect and prevent the coolant from not being fully collected due to the misalignment of the collection bottle 19. The positioning groove 18 of the fixing frame 17 can be designed as an embedded soft rubber support, which can not only fix the collection bottle 19, but also prevent the collection bottle 19 from breaking due to collision. The inner wall of the hopper 20 can be coated with an anti-adhesion coating to reduce the adhesion of oil stains in the coolant to the hopper wall, ensuring that all liquid flows into the collection bottle 19. The collection bottle 19 can be made of glass or plastic and should be emptied periodically. The outlet of the hopper 20 can be equipped with a replaceable filter element to intercept iron filings in the coolant and protect the collection bottle 19 and the subsequent reuse system. A flip-top protective door can be installed on the open side of the mounting bracket 17, which facilitates the replacement of the collection bottle 19 and can be closed when not in operation to prevent external dust and debris from entering and contaminating the coolant.

[0029] Please see Figure 1 - Figure 7 The hopper 20 is located directly below the liquid outlet pipe 16, and one side of the fixing frame 17 is open. The inner wall of the positioning groove 18 is in contact with the outer wall of one side of the collection bottle 19.

[0030] Furthermore, a support frame 21 is fixedly connected to the top of the tabletop 1, and a first hydraulic cylinder 22 is fixedly connected to the top of the support frame 21. A pressure block is fixedly connected to the output end of the first hydraulic cylinder 22, and the outer wall of the pressure block is in contact with the inner wall of the material hole of the hopper 2. A second hydraulic cylinder 23 is fixedly connected to the top of the tabletop 1, and the output end of the second hydraulic cylinder 23 is slidably inserted into the inside of the hopper 2. Through the integrated design of the switching mechanism, feeding mechanism, and receiving mechanism, the automatic briquetting, feeding, collection, and coolant recovery of iron filings are realized. The structure is compact and easy to operate. At the same time, through the optimization of wear-resistant, leak-proof, flow-guiding, and positioning details, the durability, reliability, and environmental performance of the equipment are significantly improved. The support frame 21 can adopt a box beam structure with internal cross stiffeners to improve overall rigidity and prevent bending deformation under the high pressure of the first hydraulic cylinder 22, which would affect the accuracy of the pressing block. The outer surface of the pressing block can be machined with multiple annular grooves or knurled patterns to enhance the engagement with the iron filings and prevent slippage during extrusion, which could lead to uneven density. The working principle of the above embodiments is as follows: In use, iron filings are placed inside the hopper 2. The first hydraulic cylinder 22 presses down on the iron filings to compress them into block-shaped materials. At this time, the cylinder 5 pulls the first baffle 6, which disengages from the fixed groove 3 and slides into the through groove 8. At this time, the top of the first baffle 6 is flush with the top of the table 1. Then, the second hydraulic cylinder 23 pushes the block-shaped iron filings out of the hopper 2, thereby achieving the effects of automatic compression into blocks and automatic feeding, making operation more convenient. The second hydraulic cylinder 23 pushes the blocky iron filings out of the hopper 2. At this time, the blocky iron filings automatically slide down through the inclined plane 14 and fall into the collection box for collection and storage, thereby achieving the effect of automatic collection. The inclined plane 14 can reduce the situation of the blocky iron filings scattering after falling. The guard plate can guide the material and reduce the situation of falling from the side. The coolant guided by the arc-shaped groove 10 flows into the groove 15 and is discharged through the outlet pipe 16 inside the groove 15. The discharged coolant is guided through the hopper 20 and collected and stored in the collection bottle 19. This setting can prevent the coolant from spilling. The collection bottle 19 is positioned by the positioning groove 18, which can achieve better collection effect and prevent the coolant from not being fully collected due to the misalignment of the collection bottle 19.

[0031] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
