Description

Technical Field

[0001] This utility model relates to the field of scrap steel processing, and specifically to a scrap steel crushing and recycling device. Background Technology

[0002] In the field of scrap steel processing, the crushing and recycling of scrap steel is a crucial step in achieving resource recycling. However, existing scrap steel crushing processes suffer from numerous problems, the most prominent being the generation of large amounts of dust. During the operation of traditional scrap steel crushing equipment, rust, silt, and fine metal fragments adhering to the surface of the scrap steel, generated by the crushing force, are all thrown into the air, forming substantial amounts of dust. This dust not only severely pollutes the working environment and affects the health of operators but may also lead to a decline in surrounding air quality. Furthermore, the presence of large amounts of dust can accelerate the wear and tear of internal equipment components, reducing equipment lifespan and increasing maintenance costs. Therefore, developing a scrap steel crushing and recycling device that can effectively solve the dust problem during the scrap steel crushing process is of significant practical importance.

The dust collection assembly 5 includes a dust collection hood 51, a dust collection hood 2, a duct 1 52, a duct 2 53, and a processing box 54. The dust collection hood 51 is connected to the upper end of the box body 21 and is connected to the processing box 54 through the duct 1 52. The box body 21 is evenly provided with dust collection holes 24, which are positioned directly opposite the filter screen plate 23.

[0020] It achieves integrated operation of scrap steel crushing, impurity and steel block separation, and dust collection and treatment, effectively improving the efficiency and quality of scrap steel recycling, while improving the working environment and reducing the adverse effects of dust on equipment and the environment.

[0021] In a further preferred embodiment, the impurity discharge assembly 3 includes a conveyor belt 31, a drive mechanism 32, and a collection box 33. The right end of the conveyor belt 31 is positioned directly below the feed filter plate 23, and the collection box 33 is positioned at the left end of the conveyor belt 31. The drive mechanism 32 drives the conveyor belt 31 to move cyclically, sending impurities on the conveyor belt 31 into the collection box 33. In the impurity discharge assembly, the right end of the conveyor belt 31 is positioned directly below the feed filter plate 23. The motor output shaft of the drive mechanism 32 is connected to a drive sprocket, and the drive roller of the conveyor belt 31 is fitted with a driven sprocket; the two are engaged by a chain. The conveyor belt 31 is fitted over the drive roller, and its internal chain teeth match the chain. When the motor starts, the drive sprocket drives the driven sprocket, causing the drive roller to rotate. Through the engagement of the chain and chain teeth, and the friction between the conveyor belt 31 and the driven roller, cyclical movement is achieved, sending impurities to the left-end collection box 33. The driven roller provides support and guidance, maintaining the tension and stable operation of the conveyor belt. Both the conveyor belt (31) and the drive mechanism (32) are existing technologies.

[0022] In a further preferred embodiment, the steel block discharge assembly 4 includes a second conveyor belt 41, a second drive mechanism 42, and a second collection box 43. The left end of the second conveyor belt 41 is located at the lower discharge end of the discharge screen plate 24, and the second collection box 43 is located at the right end of the second conveyor belt 41. The second drive mechanism 42 drives the second conveyor belt 41 to move cyclically, feeding the steel blocks on the second conveyor belt 41 into the second collection box 43. In the steel block discharge assembly, the left end of the second conveyor belt 41 is located at the lower discharge end of the discharge screen plate 23. The motor output shaft of the second drive mechanism 42 is connected to a drive sprocket.

The second conveyor belt 41 is fitted around the outer surface of the drive roller, and its interior is provided with chain teeth that match the chain, and the chain tightly meshes with these chain teeth. After the motor is powered on, the output shaft drives the drive sprocket to rotate at high speed. Through the meshing transmission between the chain and the sprocket, the driven sprocket rotates synchronously, thereby driving the drive roller of conveyor belt 41 to rotate. As the drive roller rotates, due to the synergistic effect of the chain and the teeth of conveyor belt 41, as well as the friction between conveyor belt 41 and the driven roller, conveyor belt 41 begins to move in a cycle, transporting the steel blocks that slide off the feed filter plate 23 to the right end and into collection box 43. Both conveyor belt 41 and drive mechanism 42 are existing technologies.

[0023] In a further preferred embodiment, the crushing assembly 2 also includes a reduction motor 24 and a gear transmission assembly 25. The reduction motor 24 drives two sets of crushing rollers 22 to rotate via the gear transmission assembly 25. The reduction motor 26 outputs power, and its output shaft is connected to the driving gear in the gear transmission assembly 25. The driving gear meshes with the driven gears on the two sets of crushing rollers 22. When the reduction motor 26 is running, the output shaft drives the driving gear to rotate. The driving gear, through meshing with the driven gears, transmits power to the two sets of crushing rollers 22, causing the two sets of crushing rollers 22 to rotate in a predetermined direction and speed, thereby crushing the scrap steel.

[0024] In a further preferred embodiment, the processing box 54 is equipped with a filter assembly 541, a fan 542, and a dust collection assembly 543. The front end of the filter assembly 541 is connected to duct 1 52 and duct 2 53, and the rear end of the filter assembly 541 is connected to the front end of the fan 542 via a pipe. The rear end of the fan 542 is connected to the dust collection assembly 543. The front end of the filter assembly 541, connected to duct 1 52 and duct 2 53, is used to receive dust-laden gas collected from the box 21. The filter assembly 541 is generally composed of multiple layers of filter screens with different filtration precisions, such as a coarse filter screen for filtering larger dust particles and a fine filter screen for filtering finer dust particles. The fan 542 is located at the rear end of the filter assembly 541 and is connected to the filter assembly 541 via a pipe. The fan 542 is generally a centrifugal fan, consisting of a motor and an impeller. The dust collection assembly 543 is connected to the rear end of the fan 542 and is usually in the form of a dust collection bag or dust collection box. This effectively treats the collected dust and reduces dust emissions into the environment.

[0025] As a further preferred embodiment, the feeding assembly 1 includes a conveyor belt 311 and a drive mechanism 32. The right end of the conveyor belt 311 is located at the feed inlet of the housing 21. The drive mechanism 32 drives the conveyor belt 311 to move cyclically, feeding the scrap steel on the conveyor belt 311 into the housing 21. In the feeding assembly, the right end of the conveyor belt 311 is aligned with the feed inlet of the housing 21. The output shaft of the motor of the drive mechanism 32 is equipped with a drive sprocket, and the driven sprocket on the drive roller of the conveyor belt 31 is connected to it by a chain. The conveyor belt 311 is fitted over the drive roller, and the chain teeth mesh with the chain. The motor drives the drive sprocket, which in turn rotates the driven sprocket through the chain, driving the drive roller and causing the conveyor belt 31 to move cyclically, feeding the scrap steel into the housing 21. The driven roller supports the conveyor belt 311, ensuring its tension and guiding it to move along a predetermined path, ensuring smooth scrap steel conveying. The conveyor belt 311 and the drive mechanism 32 are existing technologies.

[0026] like Figures 1-3As shown, the working principle of this utility model is as follows: Scrap steel is fed into the feed end of the housing 21 via the conveyor belt 311 in the feeding assembly 1 under the action of the drive mechanism 312. After entering the housing 21, the scrap steel is crushed by the crushing roller 22 located on the upper side inside the housing 21. The crushing roller 22 is driven to rotate by the reduction motor 26 through the gear transmission assembly 25, performing operations such as squeezing and tearing on the scrap steel, breaking it into smaller steel blocks and impurity particles. The crushed material falls onto the discharge filter plate 23. Due to the filtering effect of the discharge filter plate 23, the smaller impurity particles pass through the filter plate and fall onto the conveyor belt 31 of the impurity discharge assembly 3 located directly below it. Driven by the drive mechanism 32, the conveyor belt 31 moves cyclically, sending the impurities into the collection box 33. Larger steel blocks move downwards along the feed filter plate 23 to its lower discharge end, landing on the conveyor belt 41 of the steel block discharge assembly 4. Driven by the drive mechanism 42, the conveyor belt 41 circulates, feeding the steel blocks into the collection box 43. Throughout the process, the dust collection assembly 5 plays a role. The dust collection hood 51 connects to the upper end of the box 21, collecting the dust generated inside the box 21 and sending it into the processing box 54 through the air duct 52. At the same time, the box 21 is evenly distributed with dust collection holes 24 facing the feed filter plate 23. The dust collection holes 24 are connected to the dust collection hood 54, which also sends the collected dust into the processing box 54 for processing through the air duct 53.

[0027] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
