When balls need to be unloaded, the hydraulic pump is started, the two hydraulic cylinders work simultaneously, the ball unloading door is automatically opened upwards under the thrust action of the hydraulic cylinders, and the medium balls flow out through the ball unloading pipe to finish the ball unloading of the tower mill. When the ball discharging door is required to be closed, the hydraulic pump is started, the hydraulic cylinder works, the ball discharging door is automatically closed under the action of the tensile force of the hydraulic cylinder, when the ball discharging pipe is attached to the sealing gasket of the ball discharging door, the hydraulic cylinder continues to work, and the ball discharging door is tensioned until the ball discharging door is sealed.
Description
Technical Field
The utility model relates to a tower mill technical field, specific convenient, swift tower mill that unloads medium ball unloads ball mechanism in tower mill that says so.
Background
With the wide application of tower mills in the field of ore grinding, the maintenance problem of tower mills is gradually emphasized by people. When the existing tower mill is in a long halt time, the medium balls in the cylinder body of the tower mill need to be unloaded, otherwise the medium balls are hardened with ore pulp to cause a vehicle pressing phenomenon, the tower mill cannot be started, and normal production is recovered.
Disclosure of Invention
An object of the utility model is to provide a more convenient and swift tower mill unloads ball mechanism. So as to shorten the overhaul time and recover the production more quickly.
The purpose of the utility model is realized like this: a ball unloading mechanism of a tower mill comprises: connect the ball tube of unloading on tower mill main part bottom lateral wall, sealed the pad, unload goal, its characterized in that: the ball discharging pipe and the ball discharging door form an elbow structure, and an annular sealing gasket is arranged at the bending position between the ball discharging pipe and the ball discharging door; hydraulic cylinders in a double-hydraulic-cylinder driving mode are arranged at symmetrical positions between the ball discharging pipe and the ball discharging door, one end of each hydraulic cylinder is fixed on the ball discharging pipe, and the other end of each hydraulic cylinder is fixed on the ball discharging door; a swing mechanism which is convenient for opening the ball unloading door is arranged at the inner bend of the elbow structure between the ball unloading pipe and the ball unloading door. When balls need to be unloaded, the hydraulic pump is started, the two hydraulic cylinders work simultaneously, the ball unloading door is automatically opened upwards under the thrust action of the hydraulic cylinders, and the medium balls flow out through the ball unloading pipe to finish the ball unloading of the tower mill. When the ball discharging door is required to be closed, the hydraulic pump is started, the hydraulic cylinder works, the ball discharging door is automatically closed under the action of the tensile force of the hydraulic cylinder, and when the ball discharging pipe is attached to the sealing gasket of the ball discharging door, the hydraulic cylinder continues to work to pull the ball discharging door tightly until the ball discharging door is sealed.
The hydraulic cylinder driving device of the ball unloading door is replaced by an electric cylinder or an air cylinder.
The drive form of pneumatic cylinder is manual or electronic according to the on-the-spot needs.
The cross section shapes of the ball unloading pipe and the ball unloading door are circular or square.
When the mechanism is operated, the telescopic stroke of the hydraulic cylinder can be controlled by the hydraulic pump, so that the opening size of the ball discharging door can be effectively controlled, and the flow of the ball can be conveniently controlled during ball discharging. The ball discharging pipe and the ball discharging door are provided with rotary mechanisms, and when the hydraulic cylinder works, the rotary path of the ball discharging door can be effectively limited.
The utility model discloses a tower mill ball unloading mechanism just can be fine this problem of solution, and this mechanism main part is formed by standard seamless steel pipe, flange steel sheet and round pin axle welding, and processing is simple and easy, and the pneumatic cylinder that uses also is standard ordinary pneumatic cylinder. The mechanism is simple in operation for workers, can greatly shorten the on-site maintenance time, and can recover production as soon as possible.

FIG. 2 is a schematic diagram of the closing of the ball discharging door during the operation of the utility model;
figure 3 is a schematic sketch for opening the ball discharging door during the work of the utility model.
Description of the main components in the drawings: the serial number 1 is a ball discharging door, the serial number 2 is a hydraulic cylinder, the serial number 3 is an annular sealing gasket, the serial number 4 is a slewing mechanism, and the serial number 5 is a ball discharging pipe.
The present invention will be described in further detail below by way of examples with reference to the accompanying drawings, but the following examples are merely illustrative of the present invention and do not represent the scope of the present invention as defined in the claims.
Detailed Description
As shown in the attached drawing 1, 5 in the drawing is a ball discharging pipe connected to the side wall of the bottom of a tower mill main body, 3 is an annular sealing gasket, 1 is a ball discharging door, the ball discharging pipe 5 and the ball discharging door 1 form an elbow structure, and the annular sealing gasket 3 is arranged at the bending position between the ball discharging pipe 5 and the ball discharging door 1; the hydraulic cylinders 2 which adopt a double-hydraulic-cylinder driving mode are arranged at symmetrical positions between the ball discharging pipe and the ball discharging door, one end of each hydraulic cylinder is fixed on the ball discharging pipe, and the other end of each hydraulic cylinder is fixed on the ball discharging door; a swing mechanism 4 which is convenient for opening the ball discharging door is arranged at the inner bend of the elbow structure between the ball discharging pipe and the ball discharging door.
As shown in the attached figure 2, when the tower mill normally works, a ball discharging door 1 of the mechanism is in a closed state, two hydraulic cylinders 2 on two sides tension the ball discharging door 1, and a medium ball and ore pulp are sealed in a mill cylinder body.
As shown in the attached figure 3, when the tower mill is stopped and ball unloading is needed, a hydraulic pump is started, two hydraulic cylinders 2 on two sides of the mechanism work simultaneously, a ball unloading door 1 rises upwards slowly around a fixed path limited by a rotating mechanism 4, medium balls in the tower mill automatically flow outwards through a ball unloading pipe 5, the medium balls in the mill are not required to be unloaded completely, and when the medium balls do not automatically flow outwards, ball unloading is completed. When the mill needs the during operation, need close and unload ball door 1, at first the remaining medium ball that the clearance unloaded 5 flanges of bulb department, clean the sealed pad 3 surfaces of 5 flange gaskets of ball pipe of unloading with the clear water, start the hydraulic pump, two pneumatic cylinders 2 simultaneous workings in this mechanism both sides, unload ball door 1 around slewing mechanism 4 along former route slowly closed, when unloading ball pipe 5 and the sealed pad 3 laminating on unloading ball door 1, pneumatic cylinder 2 continues to work, taut ball door 1 of unloading, until sealed, thereby realized the utility model discloses a purpose.
