Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal gangue sorting technology, specifically to a sorting and processing device for coal gangue processing. Background Technology
[0002] Coal gangue is a solid waste generated during coal mining and washing. Its composition is complex, containing coal, rock, clay, and high-moisture impurities. Different particle sizes of coal gangue have different uses; therefore, during sorting, the material needs to be classified by particle size through screening. However, during the particle size sorting process, screen blockage not only reduces screening quality but also requires the sorting device to be shut down to clean the blocked coal gangue, directly affecting sorting efficiency and equipment stability. Therefore, this application proposes a coal gangue processing sorting device to solve the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] like Figure 1-3As shown, this utility model provides a technical solution: a sorting and processing device for coal gangue processing, including a crushing box 1, a crushing shaft 3 installed inside the crushing box 1, and the crushing shaft 3 driven by a motor 4. Coal gangue is added from the top of the crushing box 1, and the crushing shaft 3 rotates under the drive of the motor 4 to perform preliminary crushing of the coal gangue, ensuring that the coal gangue can be screened for different particle sizes after entering the sorting box 2. After crushing, the coal gangue slides from the bottom of the crushing box 1 into the feed inlet on the top side of the sorting box 2 for sorting. The bottom outlet of the crushing box 1 is connected to the sorting box 2. The upper side of the sorting box 2 has multiple doors for easy inspection and maintenance. The sorting box 2 is tilted at an angle greater than 30 degrees to ensure that the coal gangue can slide down automatically under gravity. The lowest point of the sorting box 2 is the outlet for large-diameter particles. The bottom side wall of the sorting box 2 is equipped with multiple screens 5 with different aperture sizes arranged sequentially from high to low. The aperture size of the screens 5 increases progressively from high to low. Each screen 5 has a [missing information - likely a device or structure] directly below it. The system includes a discharge box 6 with a sloping bottom wall and a discharge port on its lower side. Coal gangue slides down through multiple screens 5. The uppermost screen 5 has a smaller aperture, suitable for initial screening of the smallest coal gangue particles. The remaining screens 5 then separate the coal gangue into different sizes, allowing for grading and screening. The material is then discharged through the discharge box 6. A rotating plate 7 is mounted at the top of the discharge box 6, with several ejector blocks 8 installed on its upper side. The ejector block 8 on plate 7 can be inserted into the corresponding aperture on the screen 5. One end of the rotating plate 7 is connected to a rotating shaft 9, which is installed on the discharge box 6. The rotating shaft 9 is driven by a forward and reverse motor 10. During the screening process, the forward and reverse motor 10 will drive the rotating shaft 9 to rotate, causing the rotating plate 7 to rotate and fit against the bottom side of the screen 5. At this time, the ejector block 8 will connect with the aperture on the screen 5, thereby ejecting the coal gangue material stuck in the aperture on the screen 5 and realizing automated and timed cleaning of the blocked aperture on the screen 5.
[0021] The operational steps for this application are as follows:
[0022] Coal gangue is added from the top of the crushing box 1. Driven by the motor 4, the crushing shaft 3 rotates to perform initial crushing of the coal gangue. Then, the coal gangue slides from the bottom of the crushing box 1 into the feed inlet on the top side of the sorting box 2. The coal gangue slides down through multiple screens 5 in sequence. The uppermost screen 5 has a smaller aperture and can be used for initial screening of the smallest coal gangue particles. Then, the coal gangue passes through the remaining multiple screens 5 in sequence for screening. This allows for the classification and screening of coal gangue of different particle sizes according to particle size. During the screening process, the forward and reverse motors 10 drive the rotating shaft 9 to rotate, causing the rotating plate 7 to rotate and adhere to the bottom side of the screen 5. At this time, the ejector block 8 will connect with the aperture on the screen 5 to eject the coal gangue stuck in the aperture on the screen 5, realizing automated and timed cleaning of the blocked aperture on the screen 5.
