Abstract
The utility model relates to a gravity blanking ore feeder. A conical funnel is connected with a square blanking hopper. The square blanking hopper is connected with a flange of an ore discharge inner cylinder with external threads, and the external threads of the ore discharge inner cylinder are matched with internal threads of an ore discharge outer cylinder with the internal threads. A horizontally-arranged belt conveyor is arranged below the ore discharge outer cylinder. An annular rotary plate is welded to the outer cylinder wall of the ore discharge outer cylinder. A manual gate plate is arranged on the square blanking hopper. The gravity blanking control method comprises the steps that firstly, the opening degree of the manual gate board in the square blanking hopper is adjusted; secondly, the annular rotary plate welded to the outer cylinder wall of the ore discharge outer cylinder is rotated, the distance between an exit of the ore discharge outer cylinder and the bearing face of the belt conveyor is vertically adjusted through the threads, and the falling speed and the falling amount of ore charge depending on gravity are controlled. Through the gravity blanking ore feeder, unpowered, even and easy control over the ore feeding amount of a dressing plant can be achieved, and the beneficial effects of saving energy, reducing consumption and lowering the labor intensity of staff and operation cost are achieved.
Description
Technical field
The utility model relates to a kind of preparation equipment, particularly a kind of gravity blanking ore feeder.
Background technology
In the mineral processing production of industrial and mining enterprises, in ore dressing plant after fragmentation, the particle diameter qualified mineral aggregate that is 8mm-25mm, be conventionally stored in ore storage bin, in order to meet the technological requirement of lower road ore-dressing practice, next procedure will be accomplished evenly, be inputted continuously to qualified mineral aggregate.In ore dressing plant, traditional ore deposit mode of giving is that the electricity ore feeders such as rock feeder, oscillating feeder, belt feeder that shake are installed on qualified ore storage bin feed opening.In production practice, show following shortcoming: first the rock feeder of different model all needs power consumption; Next is that these rock feeders are installed complexity; The 3rd is that these rock feeders have movable parts, and fault rate is high, maintenance capacity is large; The 4th is that these rock feeders all will be installed stand-by facility.
Summary of the invention
The technical problems to be solved in the utility model is to provide the unpowered ore feeder of a kind of gravity blanking, can make the mine-supplying quantity in ore-dressing practice easily be controlled, and accomplishes evenly, gives continuously ore deposit, saves the energy, reduces employee's labour intensity.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of gravity blanking ore feeder, comprises the conical hopper being fixedly connected with ore storage bin and the cubic hopper being fixedly connected with conical hopper; The lower edge of described cubic hopper is connected with the flange that is provided with externally threaded ore discharge inner cylinder, the outside thread of ore discharge inner cylinder and the screw-internal thread fit of establishing female ore discharge out cylinder; The below of ore discharge out cylinder install horizontal arrangement belt transporter.Described ore discharge inner cylinder and ore discharge out cylinder are upright layout, perpendicular to the belt transporter of horizontal arrangement.The outer tube wall of described ore discharge out cylinder is welded with annular arrangement rotating disc.Described cubic hopper is provided with manual flashboard.
Adopt the gravity blanking control method of above-mentioned a kind of gravity blanking ore feeder, the one, regulate the opening degree of described manual flashboard in cubic hopper, control speed and quantity that mineral aggregate relies on gravity fall; The 2nd, rotation is welded on the annular arrangement rotating disc of the outer tube wall of described ore discharge out cylinder, and the distance d by between the outlet of screw thread up-down adjustment ore discharge out cylinder and belt transporter carrying surface, controls speed and quantity that mineral aggregate relies on gravity fall.
The beneficial effects of the utility model are: adopt the utility model to realize unpowered, even, easily control, the beneficial effect that reach energy-saving and cost-reducing, reduces staff labor intensity and operating cost to the mine-supplying quantity in ore dressing plant.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
embodiment 1as shown in Figure 1: a kind of gravity blanking ore feeder, the top of conical hopper 1 is connected with ore storage bin, the upper limb of four directions hopper 2 is fixedly connected with the lower edge of conical hopper 1, the lower edge of four directions hopper 2 is connected with the flange 3 that is provided with externally threaded ore discharge inner cylinder 4, the outside thread of ore discharge inner cylinder 4 and the screw-internal thread fit of establishing female ore discharge out cylinder 6; The below of ore discharge out cylinder 6 install horizontal arrangement belt transporter 7.Described ore discharge inner cylinder 4 and ore discharge out cylinder 6 are upright layout, perpendicular to the belt transporter 7 of horizontal arrangement.The outer tube wall of described ore discharge out cylinder 6 is welded with annular arrangement rotating disc 5
.described cubic hopper 2 is provided with manual flashboard 8.
The width of described cubic hopper 2 is 100mm-300mm.
Described manual flashboard 8 is that thickness is the iron plate of 6mm-10mm.
The wall thickness of described ore discharge inner cylinder 4 and ore discharge out cylinder 6 is 10mm-30mm, and internal diameter is 150mm-350mm.
Screw thread in described ore discharge inner cylinder 4 and ore discharge out cylinder 6 is that single line or multi-thread, trapezoidal or saw thread, pitch are 5mm ~ 10mm.
During operation, open manual flashboard 8, mineral aggregate 9 in ore storage bin utilizes gravity pressure that mineral aggregate 9 is freely pressed and fallen on belt transporter 7, on belt, natural packing reaches certain thickness mineral aggregate 9 and is full of whole feeder inner chamber, start belt transporter 7, the speed of belt is 0.2m/s-2m/s, and along with travelling forward of belt, mineral aggregate 9 is transported to continually next production process and carries out ore-dressing practice.By cw or left-hand revolution annular arrangement rotating disc 5, ore discharge out cylinder 6 just can be along ore discharge inner cylinder 4 up-and-down movements, again in conjunction with the belt speed of belt transporter 7, requirement according to lower road beneficiating process to mine-supplying quantity, regulate the distance d between 6 outlets of ore discharge out cylinder and belt transporter 7 carrying surfaces, rationally control the thickness of the mineral aggregate 9 on belt, thereby reach the object of controlling belt mine-supplying quantity.Overcome traditional rock feeder power consumption, had fault, will keep in repair, want standby defect.
