Referring to fig. 1 to 3, a crushing and mixing device for red mud building material filler according to an embodiment of the present application will now be described. A red mud building material filling material crushing and mixing device comprises: a coarse crushing unit and a fine crushing unit. The coarse crushing unit comprises at least one group of crushing pair rollers and is suitable for receiving the red mud and discharging the red mud after coarse crushing; the fine crushing unit is suitable for receiving the red mud discharged from the coarse crushing unit and discharging the red mud after fine crushing;
the fine crushing unit includes: a passive outer roller and an active inner roller. The inner peripheral wall of the driven outer roller is provided with internal teeth, the front end is an inlet, the rear end is an outlet, and the front part of the driven outer roller is obliquely arranged with high front and low rear part; the outer peripheral wall of the driving inner roller is provided with external teeth, the external teeth are meshed with the internal teeth, and the meshing coincidence ratio is less than 1; red mud discharged from the coarse crushing unit is discharged into the front side of the driving inner roller from the inlet of the driven outer roller, enters the rear side of the driving inner roller after passing through the meshing position of the external teeth and the internal teeth, and is discharged from the outlet of the driven outer roller.
The active inner roller is hollow and is used for containing dry powder and injecting high-pressure gas; the side wall of the driving inner roller is provided with a discharging hole, one end of the discharging hole is communicated with the inner cavity of the driving inner roller, and the other end of the discharging hole extends to the stress side of the external teeth to form a discharging hole; the discharging port is internally provided with a pressing valve, and the pressing valve is suitable for being pressed by the internal teeth to open and release the dry powder in the driving inner roller when the external teeth are meshed with the internal teeth.
Compared with the prior art, the red mud building material filling material crushing and mixing equipment provided by the embodiment of the application has the advantages that the red mud can be coarsely crushed into small particles through the coarse crushing unit, then the small-particle red mud enters the fine crushing unit, and the fine crushing unit is meshed with the inner teeth of the driven outer roller through the outer teeth of the driving inner roller, so that the red mud is rolled into proper powder. In the process, the pressing valve is opened when the external teeth are meshed with the internal teeth, so that dry powder (dry additive) in the active inner roller flows out under the action of high-pressure gas and is directly mixed with the rolled red mud, on one hand, the added additive and the red mud can be quickly and uniformly mixed, and on the other hand, the humidity and viscosity of the red mud can be reduced, and the possibility that the red mud is adhered to the active inner roller and the passive outer roller is reduced. Because the contact ratio of the external teeth and the internal teeth is less than 1, in the process that the active inner roller drives the passive outer roller, the external teeth and the internal teeth can continuously collide, on one hand, the impact enhances the crushing effect, and on the other hand, the active inner roller and the passive outer roller generate vibration, and red mud adhered to the active inner roller and the passive outer roller shakes off.
The coarse crushing unit adopts crushing pair rollers, and the large red mud is crushed into small particles through the extrusion of the crushing pair rollers. The coarse crushing unit may also be accompanied by a receiving hopper for guiding the red mud between the crushing pairs of rollers, in particular with reference to the construction of the crushing plant generally known in the art.
The fine crushing unit is positioned below the coarse crushing unit, so that the red mud discharged by the coarse crushing unit can be directly taken in by the inlet of the passive outer roller, or the red mud which falls off after crushing the crushing roller is taken in by the inclined guide groove, and then the red mud is guided to the inlet of the passive outer roller by the inclined guide groove.
The passive outer roller is cylindrical, the front end of the passive outer roller is open to form an inlet, and the rear end of the passive outer roller is open to form an outlet. The passive outer roller is supported by the riding wheels to form a front-high and rear-low inclination, and can freely rotate around the central axis, so that red mud added from the inlet gradually moves towards the outlet in the rotation process of the passive outer roller; specifically, the passive outer roller is supported by a front group of riding wheels and a rear group of riding wheels, the front group of riding wheels are respectively supported on two sides below the front end of the passive outer roller, and the rear group of riding wheels are respectively supported on two sides below the rear end of the passive outer roller.
The driving inner roller is cylindrical, and two ends of the driving inner roller are sealed to form a hollow inner cavity. The driving inner roller is positioned in the driven outer roller, and the central axis of the driving inner roller is parallel to the central axis of the driven outer roller. The driving inner roller can support and transmit power through rotating shafts at the centers of two ends, and the rotating shaft at one end is hollow and is used for adding dry powder.
Red mud discharged from the coarse crushing unit is discharged into the front side of the driving inner roller from the inlet of the driven outer roller, so that when the driving inner roller and the driven outer roller rotate, the red mud on the front side of the driving inner roller can enter the meshing position of the external teeth and the internal teeth, and the red mud is finely crushed; the crushed red mud enters the space at the rear side of the active inner roller, gradually moves towards the outlet in the rotation process of the passive outer roller, and finally is discharged from the outlet of the passive outer roller.
The inner teeth of the inner wall of the passive outer roller and the outer teeth of the outer wall of the active inner roller are meshed with each other and are mainly used for rolling red mud, so that tooth shapes of the inner teeth and the outer teeth are not required to be standard tooth shapes, and a high-precision machining mode is not required to be adopted, for example, angle steel inverted welding can be adopted in implementation to form the inner teeth and the outer teeth on the inner wall of the passive outer roller and the outer wall of the active inner roller. The contact ratio of the external teeth and the internal teeth is smaller than 1, so that after the external teeth and the internal teeth of the former group are separated, the external teeth and the internal teeth of the latter group are not contacted, a certain impact is formed when the external teeth and the internal teeth of the latter group are contacted, red mud is crushed better, and the driven external roller and the driving internal roller vibrate to make the adhered red mud fall. In specific implementation, the contact ratio of the external teeth and the internal tooth engagement can be adjusted by changing parameters such as tooth shapes, tooth pitches, tooth numbers, modulus, pressure angles and the like of the external teeth, so that the contact ratio is controlled to be smaller than 1, and specific design processes refer to a common gear design mode and are not repeated herein.
The side wall of the driving inner roller is provided with a discharge hole in a drilling mode, and a pressing valve is arranged at a discharge hole of the discharge hole, so that the pressing valve can be opened only when the external teeth are meshed with the internal teeth, and dry powder is directly mixed into red mud under the action of high-pressure gas; after the external teeth are separated from the internal teeth, the pressing valve is closed, so that high-pressure gas leakage is avoided, and the inside of the driving inner roller is kept at high pressure. In addition, the pressure of the high-pressure gas can be regulated, and the proportion of the dry powder mixed into the powder can be regulated.
Referring to fig. 3, as a specific embodiment of the crushing and mixing device for the red mud building material filling material provided by the application, the discharging hole comprises a connecting section and an outlet section, the front end of the outlet section extends to the stress side of the external teeth to form a discharging hole, one end of the connecting section is communicated with the inner cavity of the driving inner roller, and the other end of the connecting section is communicated with the side wall of the outlet section.
The pressing valve comprises a valve core and a spring, wherein the valve core and the spring are arranged in the outlet section, the valve core is pushed by the spring, so that the valve core is positioned at a position for plugging the joint of the connecting section, and the valve core part protrudes out of the discharging port.
After the valve core is pressed by external force, the valve core retreats and compresses the spring, so that the valve core can leave the joint of the connecting section.
In specific implementation, the connecting section is connected to the side wall of the middle part of the outlet section, and the whole body approximates to a T shape. The valve core moves reciprocally in the outlet section to open or block the communication between the connecting section and the outlet section, so that the opening or closing of the pressing valve is realized. The valve core is pushed outwards by the spring, so that the valve core can automatically close the pressing valve when the valve core is not subjected to external force.
