The coarse material can be discharged from the release door hole 35.

[0041] The use process of this utility model:

[0042] First, pour the crushed concrete waste into the feed trough 5, then power on the equipment and start it. The waste enters the separation drum 20 along the feed pipe 6. During this process, the air flow from the blowing pipe 8 blows up the small debris, and the gas mixed with the debris is sucked into the suction pipe 11 and filtered in turn from the debris filter box 12 and the dust filter box 17.

[0043] The driving structure drives the separation drum 20 to rotate continuously, so that the waste material therein is repeatedly driven to roll, and the magnetic rod 25 absorbs the metal scraps such as steel bars mixed therein, and the smaller particles in the waste material can fall from the filter holes of the separation drum 20 and be discharged along the discharge plate 4, while the large particles of coarse material remain in the separation drum 20. When there is a lot of coarse material in the separation drum 20, the equipment is stopped and the power is turned off. Then, the control door 30 is opened and the separation drum 20 is rotated so that the sliding door 32 is facing the control door 30. The two fastening handles 34 of the sliding door 32 can be loosened, and then the sliding door 32 is pushed to the other side and the two fastening handles 34 are tightened respectively. One fastening handle 34 presses the sliding door 32, and the other fastening handle 34 keeps the thread hidden to prevent dust from entering the thread and affecting the thread. The control door 30 is closed and the equipment is started. The separation drum 20 rotates to discharge the coarse material.

[0044] After using for a period of time, rotate the mounting plate 24 so that the slot 26 is aligned with the clamping head 28, and then pull out the magnetic rod 25 for cleaning. After cleaning, insert the magnetic rod 25 back, align the slot 26 with the clamping head 28, push the mounting plate 24 into the mounting seat 27, and rotate it so that the slot 26 and the clamping head 28 are offset. This completes the cleaning of the magnetic rod 25.

[0045] When debris accumulates in the filter frame 13, the filter frame 13 can be directly pulled out to clean the debris.

[0046] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention.
