Detailed Description
As shown in fig. 1-4, the present invention includes a welded cartridge; the bottom of the welding cylinder body is provided with a conical cylinder bottom; it is characterized in that a plurality of medium balls are contained in the conical cylinder bottom below the stirring screw.
The bottom of the conical barrel is provided with a transversely arranged volleyball pipeline, the barrel bottom is connected with the volleyball pipeline through a vertically arranged guide pipeline, an inlet is formed in the volleyball pipeline, the inlet end of the guide pipeline is communicated with the barrel bottom, and the outlet end of the guide pipeline is communicated with the inlet of the volleyball pipeline.
The volleyball pipeline is transversely provided with a through transmission shaft, the transmission shaft is rotatably connected with the volleyball pipeline, and the transmission shaft is provided with helical blades; one side of the volleyball pipeline, which is far away from the inlet, is provided with a volleyball discharging port.
The transmission shaft is driven by a driving motor to rotate freely in the volleyball pipeline.
Preferably, a flexible fan plate is arranged in the volleyball pipeline and on the transmission shaft, the flexible fan plate is positioned below the guide pipeline, the flexible fan plate is perpendicular to the transmission shaft, and a rotation space corresponding to the position of the flexible fan plate is longitudinally arranged on the volleyball pipeline; the transmission shaft drives the flexible fan plate to rotate along with the flexible fan plate, the flexible fan plate directly reaches the bottom of the conical cylinder through the guide pipeline when rotating upwards, and directly reaches the rotation space when rotating downwards.
Preferably, one end of the transmission shaft is driven by the driving motor to rotate, and the other end of the transmission shaft penetrates out of the volleyball pipeline and is supported by a support which is assembled on the volleyball pipeline.
More preferably, the transmission shaft 5 is rotatably connected to the support 9.
More preferably, the driving motor 3 is mounted on the volleyball duct through a motor mounting plate.
Specifically, a conical barrel bottom 1 is welded at the bottom of the barrel body of the tower mill, so that the media balls 12 can be accumulated at the bottom, and the media balls 12 are prevented from abrading the bottom of the barrel body.
The bottom of the conical cylinder bottom 1 is additionally provided with a flexible fan plate 4, and the flexible fan plate 4 is assembled on a forced volleyball transmission shaft 5. With the rotation of the volleyball spiral, the scratching fan plate 4 scratches the medium balls 12 at the bottom of the conical cylinder bottom 1 repeatedly, so that the medium balls 12 are prevented from being blocked due to long-time accumulation and hindering the discharge of the medium balls 12.
Volleyball spiral 6 (transmission shaft 5 and helical blade constitute volleyball spiral 6 together) is installed in volleyball pipeline 7, 2 one end of direction pipeline and toper bobbin base 1 welding together, the pipeline other end welding is on volleyball pipeline 7, draw volleyball pipeline 7 and surpass barrel base flange, volleyball pipeline 7 volleyball mouth is in normally closed state when the tower mill normally produces, open the volleyball mouth during the maintenance, emit ore pulp and medium ball with forcing the volleyball device, convenient and fast.
