[0014] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.
[0015] like Figure 1 to Figure 2 As shown, a material rotary screening device includes a drum screening machine 1, and exhaust mechanisms 2 are symmetrically arranged on both sides of the drum screening machine 1. The top of the exhaust mechanism 2 is provided with an exhaust shell 5 with an inclined exhaust surface and which plays a protective role for the internal structure of the exhaust mechanism 2. The exhaust end of the exhaust mechanism 2 is detachably provided with a dust collecting mechanism 8 for filtering dust from the air discharged by the exhaust mechanism 2.
[0016] In this embodiment, when the drum screening machine 1 is running, the dust in the material will escape from the screen of the drum, and then the exhaust mechanism 2 is started. The exhaust mechanism 2 extracts the dust-containing air on both sides and above the drum screening machine 1 through the exhaust shell 5, and then the dust collecting mechanism 8 collects the dust in the air, and the dust-removed air passes through the dust collecting mechanism 8 and is discharged to the outside. The device significantly improves the dust collection efficiency in the screening operation through the integrated exhaust and dust collection system, effectively purifies the working environment, and protects the health of the operators.
[0017] like Figure 2 As shown, the exhaust mechanism 2 is a shell symmetrically arranged on both sides of the drum screening machine 1, the top and bottom of the shell both have openings, a rotating shaft 3 is rotatably arranged inside the shell, a plurality of blades 4 are arranged outside the rotating shaft 3, and a driving mechanism 9 for driving the rotating shaft 3 to rotate inside the shell is arranged at the end of the shell. The rotating shaft 3 is driven to rotate by a motor installed at the end of the shell, forming a powerful exhaust effect, accelerating the air circulation in the material screening process, and at the same time sucking in the dust-carrying air and efficiently purifying it through the dust collecting mechanism 8.
[0018] Specifically, the driving mechanism 9 is a motor disposed outside the housing, and an output end of the motor is connected to an end of the rotating shaft 3 to drive the rotating shaft 3 to rotate inside the housing.
[0019] like Figure 1 and Figure 2 As shown, the exhaust shell 5 is a triangular hollow shell arranged on the top of the shell, the interior of the triangular hollow shell is connected with the interior of the shell, an air inlet is penetrated on the exhaust surface of the triangular hollow shell, and a protective net 6 is arranged inside the air inlet to prevent large particles of foreign matter from entering the shell.
[0020] like Figure 1 and Figure 2 As shown, the dust collecting mechanism 8 is an air filter bag detachably arranged at the bottom of the shell body, so as to filter dust from the air exhausted from the shell body.
[0021] Working principle: During use, when the drum screening machine 1 is running, the dust in the material will escape from the screen of the drum, and then the exhaust mechanism 2 will be started. The exhaust mechanism 2 will extract the air containing dust on both sides and above the drum screening machine 1 through the exhaust shell 5, and then the dust collecting mechanism 8 will collect the dust in the air, and the dust-removed air will be discharged to the outside through the dust collecting mechanism 8. The device significantly improves the dust collection efficiency in screening operations through the integrated exhaust and dust collection system, effectively purifies the working environment, and protects the health of operators.
