Description

Technical Field

[0001] This utility model relates to the field of residue recycling technology, and in particular to a kiln tail residue recycling device. Background Technology

[0002] During the production process of high-temperature kilns in cement, ceramics, glass, and metallurgy, a large amount of residue is generated. The residue often contains metal components such as iron and aluminum, as well as unburned fuel. However, most enterprises simply landfill or pile it up without effectively recycling it, resulting in resource waste. When recycling residue, it is necessary to crush, screen, calcine, and other treatments.

[0003] In the prior art, crushing equipment for crushing residues mainly uses two crushing rollers to squeeze the residue during crushing, thereby breaking it up. In order to ensure that the residue flows accurately between the two crushing rollers, a guide plate is usually set up for guiding. When the residue pieces are large, it will cause the residue to accumulate, leading to blockage and affecting the crushing efficiency. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a kiln tail residue recycling device, comprising a housing 1, with a first rotating shaft 2 rotatably connected to both the front and rear ends of the housing 1. A pressure roller 3 is fixedly connected to the outside of the first rotating shaft 2 inside the housing 1. A fixing frame 4 is fixedly connected to both the left and right sides of the housing 1. A vertical rod 5 is slidably connected to the upper end of the fixing frame 4. A horizontal rod 6 is fixedly connected to the top of the vertical rod 5. Connecting rods 7 are fixedly connected to the lower sides of both the left and right ends of the horizontal rod 6. A gate 8 is fixedly connected to the lower end of the connecting rods 7. Guide plates 9 are fixedly connected to the front and rear sides of the top of the housing 1. Limiting rods 10 are fixedly connected to the inner sides of both the front and rear ends of the fixing frame 4. An externally mounted lifting rod 11 that slides up and down is provided. The lower end of the vertical rod 5 is fixedly connected to the upper middle part of the lifting rod 11. A spring 13 is provided on the lower external part of the limiting rod 10. A retaining ring 12 is fixedly connected to the upper external part of the limiting rod 10. Two meshing gears 14 are provided on the left and right sides of the housing 1. The middle part of the gear 14 is fixedly connected to the left and right ends of the first rotating shaft 2. An eccentric shaft 15 for pushing the lifting rod 11 down is fixedly connected to the outer side of the gear 14. A mounting plate 16 is fixedly connected to the external side of the fixing frame 4 on the right side of the housing 1. A motor 17 is fixedly connected to the rear right side of the mounting plate 16. The drive end of the motor 17 is fixedly connected to the top right end of the first rotating shaft 2.

[0024] The kiln tail residue to be processed is fed from the top of the box 1 and evenly guided between two opposing rotating pressing rollers 3 by the guide plate 9. The motor 17 drives the rear first rotating shaft 2 to rotate, which in turn drives the pressing rollers 3 to rotate. Through the transmission of the meshing gears 14, the front first rotating shaft 2 rotates synchronously in the opposite direction, so that the two pressing rollers form opposing compression crushing. When the gears 14 rotate, they drive the eccentric shaft 15 to rotate. The eccentric shaft 15 periodically pushes the lifting rod 11 down. The lifting rod 11 drives the gate 8 to move up and down through the vertical rod 5 and the horizontal rod 6. When pressing down: the gate 8 applies vertical pressure to the residue, which helps to crush large pieces of material between the pressing rollers 3 and promotes the material to pass through the gap between the pressing rollers 3. When rising: the spring 13 pushes the lifting rod 11 to reset, preparing for the next pressing down, which significantly improves the crushing efficiency and avoids the clogging problem caused by large pieces of residue.

[0025] Reference Figures 1-3 A collection hopper 18 is fixedly connected to the bottom of the housing 1, and a conveying cylinder 19 is fixedly connected to the bottom of the collection hopper 18. A drive shaft 20 is rotatably connected inside the conveying cylinder 19, and an auger 21 is fixedly connected to the outside of the drive shaft 20. The outer wall of the auger 21 is in close contact with the inner wall of the conveying cylinder 19. A second rotating shaft 22 is rotatably connected to the front end of the mounting plate 16. The left end of the second rotating shaft 22 is fixedly connected to the middle of the right end of the first rotating shaft 2. A second pulley 25 is fixedly connected to the outside of the right end of the second rotating shaft 22. A first pulley 23 is fixedly connected to the outside of the right end of the drive shaft 20. The first pulley 23 and the second pulley 25 are connected by a belt. Support plates 24 are fixedly connected to both the front and rear sides of the collection hopper 18.

[0026] The crushed residue falls into the bottom collection hopper 18, whose funnel structure ensures that the material is concentrated and enters the right inlet of the conveying cylinder 19. The first rotating shaft 2 drives the second pulley 25 to rotate through the second rotating shaft 22, and drives the first pulley 23 and the drive shaft 20 through belt transmission. The auger 21 rotates with the drive shaft 20, pushing the residue to the left along the conveying cylinder 19. The single motor drive realizes the full automation of the pressing, crushing and conveying process, simplifies the power configuration and reduces energy consumption.

[0027] Working principle: The residue to be crushed is fed into the device from the top. The guide plate 9 directs the residue between the two pressing rollers 3. The motor 17 is started, driving the connected first rotating shaft 2 to rotate, which in turn drives the pressing rollers 3. Two meshing gears 14 engage, simultaneously rotating the other first rotating shaft 2 and the pressing roller 3. The two pressing rollers 3 crush the residue. Simultaneously, the rotation of the gears 14 drives the eccentric shaft 15 to rotate. The rotating eccentric shaft 15 pushes the lifting rod 11 downwards, compressing the spring 13. The vertical rod 5 drives the horizontal rod 6 to descend, which in turn drives the connecting rod 7 and the gate 8 to descend. The descending gate 8 presses the residue downward and crushes the larger residue, promoting the crushing of the residue through the pressing roller 3. The crushed residue is collected at the right end of the conveying cylinder 19 through the collecting hopper 18. At the same time, the first rotating shaft 2 located at the front end of the box 1 drives the second rotating shaft 22 to rotate. The rotating second rotating shaft 22 drives the second pulley 25 to rotate. The rotating second pulley 25 drives the first pulley 23 to rotate through the belt, thereby driving the drive shaft 20 and the auger 21 to rotate, and driving the residue to be conveyed to the left.
