Technical Field

[0001] This utility model relates to the field of crushing technology, and in particular to a crushing device for rapid detection of heavy metals in solid waste. Background Technology

[0002] Solid waste refers to solid and semi-solid waste materials generated by humans in production, consumption, daily life and other activities. Solid waste contains different components and amounts of heavy metals. Therefore, it is necessary to test the metal elements in solid waste and strictly control the composition and content of heavy metals in solid waste. Before testing solid waste for heavy metals, it is necessary to perform pre-crushing treatment. Therefore, crushing equipment is required. Crushing equipment generally uses two symmetrically arranged crushing rollers for crushing.

[0003] However, it is worth considering that when there are a large number of crushing rollers, the position of each crushing roller needs to be adjusted and fixed individually according to different crushing requirements, which is quite inconvenient.

[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a crushing device for rapid detection of heavy metals in solid waste, so as to solve the problem that when there are a large number of crushing rollers, the position of each crushing roller needs to be individually adjusted and fixed according to different crushing requirements.

[0006] To achieve the above objectives, this utility model provides a crushing device for rapid detection of heavy metals in solid waste, including a crushing shell, a feed hopper fixedly connected to the top of the crushing shell, a discharge hopper fixedly connected to the bottom of the crushing shell, and a number of crushing components provided on the crushing shell. Each set of the crushing components includes two first rotating shafts. Crushing rollers are fixedly sleeved on the outside of the first rotating shafts. Several clearance holes are opened on the inner walls of both sides of the crushing shell. Two corresponding clearance holes are passed through the two ends of the first rotating shafts.

[0018] This specification provides one or more embodiments of a crushing device for rapid detection of heavy metals in solid waste, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes a crushing shell 1, a feed hopper 2 fixedly connected to the top of the crushing shell 1, a discharge hopper 3 fixedly connected to the bottom of the crushing shell 1, and several sets of crushing components on the crushing shell 1. Each crushing assembly includes two first rotating shafts 4. Crushing rollers 5 are fixedly sleeved on the outside of each first rotating shaft 4. Several clearance holes 7 are respectively opened on the inner walls of both sides of the crushing shell 1. Two corresponding clearance holes 7 are passed through each end of the first rotating shaft 4. Translation frames 6 located outside the crushing shell 1 are rotatably sleeved at both ends of the first rotating shaft 4. A drive structure for driving the first rotating shafts 4 to rotate is installed on the crushing shell 1, and a translation positioning mechanism for positioning the translation frames 6 is also installed on the crushing shell 1. According to the crushing requirements, the operator drives the translation frames 6 and the first rotating shafts 4 to move relative to the crushing shell 1. The distance between two adjacent first rotating shafts 4 is changed, thereby adjusting the distance between two adjacent crushing rollers 5. The translation frame 6 is positioned by the translation positioning mechanism. The solid waste to be crushed is thrown into the crushing shell 1 through the feed hopper 2. The first rotating shaft 4 and crushing roller 5 are driven to rotate by the drive structure. The crushing roller 5 crushes the solid waste. The crushed solid waste is discharged through the discharge hopper 3. It is convenient to quickly adjust the position of each crushing roller 5 according to the crushing requirements, improve production flexibility, increase efficiency, reduce downtime, and optimize production quality.

[0019] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the drive structure includes several second rotating shafts 9 rotatably mounted outside the crushing shell 1. Several servo motors 10 are fixedly connected to the crushing shell 1, and the number of second rotating shafts 9, servo motors 10, and crushing components is the same. The output end of the servo motor 10 is fixedly connected to the corresponding second rotating shaft 9. Two movable shells 8 are sleeved on the outside of the second rotating shaft 9, and the movable shells 8 are fixedly connected to the corresponding translation frames 6. Transmission units adapted to the second rotating shaft 9 and the first rotating shaft 4 are installed on the movable shells 8 respectively. The transmission unit includes a rotating sleeve 11 rotatably mounted on the movable shell 8, and the rotating sleeve 11 is sleeved outside the second rotating shaft 9. Several first guide grooves 12 are opened on the second rotating shaft 9, and several first guide grooves 12 are fixedly connected to the inner wall of the rotating sleeve 11. The first guide bar 13 is located in the corresponding first guide groove 12. The first rotating shaft 4 is fixedly connected to the first bevel gear 14 located in the movable shell 8. The rotating sleeve 11 is fixedly sleeved with a second bevel gear 15 that meshes with the first bevel gear 14. When the first rotating shaft 4, the translation frame 6 and the movable shell 8 translate, the movable shell 8 drives the first guide bar 13 to slide in the first guide groove 12 through the rotating sleeve 11. When it is necessary to drive the first rotating shaft 4 and the crushing roller 5 to rotate, the second rotating shaft 9 is driven to rotate through the servo motor 10. The second rotating shaft 9 drives the rotating sleeve 11 and the second bevel gear 15 to rotate through the first guide bar 13. The second bevel gear 15 can then drive the first rotating shaft 4 and the crushing roller 5 to rotate through the first bevel gear 14.

[0020] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the translation positioning mechanism includes several hydraulic telescopic rods 17 fixedly installed on the outside of the crushing shell 1. The outside of the crushing shell 1 is provided with a pressing seat 16 that cooperates with the movable shell 8. The telescopic ends of the hydraulic telescopic rods 17 are fixedly connected to the pressing seat 16. A guide component adapted to the translation frame 6 is installed on the crushing shell 1. An anti-slip pad 18 is fixedly connected to the side of the movable shell 8 away from the crushing shell 1, and the anti-slip pad 18 contacts the pressing seat 16. The guide component includes a support portion 19 fixedly installed on the translation frame 6. Several second guide strips 20 are fixedly connected to the outer walls of both sides of the crushing shell 1, and a second guide groove 21 adapted to the second guide strips 20 is opened on the support portion 19. The second guide strips 20 pass through the corresponding second guide grooves 21. When the first rotating shaft 4, the translation frame 6, and the movable shell 8 translate, the translation frame 6 drives the support portion... The support part 19 and the second guide groove 21 slide relative to the second guide bar 20. Through the design of the support part 19, the second guide bar 20 and the second guide groove 21, the translation frame 6, the first rotating shaft 4 and the crushing roller 5 can move smoothly in the horizontal direction relative to the crushing shell 1. After the position of the movable shell 8 and the translation frame 6 is adjusted, the hydraulic telescopic rod 17 drives the pressing seat 16 to move. The pressing seat 16 presses on the anti-slip pad 18. The pressing seat 16 applies pressure to the anti-slip pad 18 and the movable shell 8 to fix the movable shell 8 and the translation frame 6 relative to the crushing shell 1. The positions of multiple movable shells 8 and translation frames 6 can be positioned at the same time. Through the design of the anti-slip pad 18, the possibility of the movable shell 8 sliding relative to the pressing seat 16 is reduced, which makes it easy to quickly adjust the position of each crushing roller 5 according to the crushing requirements of different types of solid waste, and improves production flexibility.
