Description

Anti-overflow feeding hopper belt protection device

Technical Field

The utility model belongs to the broken band conveyer technique of ore dressing specifically is a broken belt of ore dressing prevents emitting material device.

Background

In the mineral processing and crushing industry, a belt conveyor is mineral aggregate conveying equipment which is commonly applied. For the process system with the mutually interlocked crushing equipment, the feeding mode of the belt and the crushing equipment mainly depends on a feeding hopper of a belt conveyor. The throughput that causes owing to crushing equipment's life cycle descends in the actual production process, appears the mineral aggregate and can't in time carry out the breakage, and then leads to the phenomenon that overflows from the feed hopper, if discovery and handling then can take place the hopper and give out the material accident in untimely time, leads to the belt fish tail, and the emergence of system shut down accident, and need the manpower of whole production class to handle, wastes time and energy.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: mineral aggregate can not be broken in time after the processing capacity of crushing equipment in the crusher is reduced, so that the problem that the conveying belt is damaged by the overflowing of a feeding hopper of the crusher is caused.

The utility model provides a device for solving the technical problem of timely processing when funnel flash, effectively solves the injury of flash to the belt.

An anti-overflow feeding hopper belt protection device comprises a feeding hopper, a rack and a feeding belt, wherein an electric roller and a surface increasing wheel roller are fixedly installed on the rack, the electric roller is connected with an output shaft of a driving motor, the electric roller is connected with the surface increasing wheel roller through the belt, and a pull rope switch for an emergency stop driving motor is further arranged on the rack; the feeding hopper is arranged at the left end of the frame, a feeding port of the feeding hopper is arranged below the electric roller, an overflow port is formed in a side plate of the feeding hopper, a mineral aggregate recovery hopper is arranged outside the overflow port, and the lower part of the mineral aggregate recovery hopper is combined with the feeding hopper; the overflow port is provided with a plurality of overflow ports, and the overflow ports are communicated with the overflow ports; the limit switch circuit is connected with the conveyor pull rope switch circuit.

The utility model discloses the real-time supervision funnel material emergence condition in time cuts off the belt conveyor power, makes equipment stall, its simple structure, and reasonable in design can effectively avoid the material emergence accident that feed funnel spilled over, realizes band conveyer automatic protection.

Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is a side view based on fig. 1.

In the figure, a feeding hopper 1, a mineral aggregate recovery hopper 2, an overflow port 3, a limit switch 4, a frame 5, an electric roller 6, a pull switch 7 and a dough roller 8 are arranged.

Detailed Description

Ore material is behind the batcher, get into jaw breaker coarse crushing, the ore is transported through the 1# belt, transport to the 2# belt, the material device is prevented spilling in the installation of 2# belt aircraft nose, through the transportation of 2# belt, get into PYB1200 cone crusher, the broken result of cone crusher is transported through the 4# area, after screening plant, the material of sieving returns stub cone crusher through the 5# area, stub cone crusher result returns screening plant through the 6# area, the product of sieving down transports to the thin feed bin through the 7# area. When the ore is excessively accumulated in the feeding funnel and overflows from the overflow port, the processing capacity of the crusher is reduced, at the moment, if the conveying belt continues to convey the ore to the feeding funnel at the original speed, the feeding funnel is filled, and the belt is scratched and damaged when meeting the ore.

The technical solution of the present invention is further explained with reference to the accompanying drawings 1-2, and the present invention provides a simple structure diagram, which only shows the main components related to the present solution. The parts shown in the drawings are not intended to limit the technical solution of the present invention.

The utility model provides an anti-overflow feed hopper belt protection device is equipped with feed hopper 1 on this of breaker, and feed hopper 1 installs in 5 left sides in the frame. The material is conveyed into the feeding hopper 1 by the feeding belt. The electric roller 6 is fixedly installed on the rack 5, the dough wheel roller 8 is added, the electric roller 6 is driven by the driving motor, the electric roller 6 is connected with the dough wheel roller 8 through a belt, the rack 5 is also provided with a pull switch 7, and the pull switch 7 is used for manually cutting off the power supply of the driving motor and emergently stopping the belt conveying device under the condition that the power supply cannot reach the equipment switch in time. The feeding port of the feeding funnel 1 is arranged below the electric roller 6.

An overflow port 3 is formed in a side plate of the feeding funnel 1, a mineral aggregate recovery hopper 2 is arranged outside the overflow port 3, and the lower part of the mineral aggregate recovery hopper 2 is combined with the feeding funnel 1; the overflow device is also provided with a limit switch, a limit switch 4 is fixedly arranged on the rack 5, a collision rod of the limit switch 4 is downward and is arranged outside the overflow port 3, and the distance between the collision rod and the overflow port 3 is smaller than the size of the material; the electric circuit of the limit switch 4 is electrically connected with the conveyor pull-cord switch 7.

The size of the overflow port 3 is 200 x 400mm, and the limit switch 4 is vertically arranged in the middle of the overflow port. The limit switch 4 is powered on an emergency pull-cord switch, when mineral aggregate overflows from the overflow port 3, the material touches the limit switch 4, and then the belt conveyor is powered off, and the belt stops. When the mineral aggregate blocked by the funnel is treated, the overflowed mineral aggregate is recovered from the mineral aggregate recovery port 2 and returns to the crushing process flow.

When the processing capacity of the crusher cannot be matched with the feeding speed of a feeding belt, the overflow material touches a limit switch in the falling process, a limit switch collision bar is pushed by the material overflowing from an overflow port, and the limit switch is linked with an anti-lying or emergency pull-cord switch of the belt conveyor and is connected with the pull-cord switch so as to cut off the power supply of the belt conveyor and stop the operation of the belt conveyor. The falling mineral aggregate falls into a mineral aggregate recovery port and returns to a feeding hopper.

The utility model discloses simple structure, reasonable in design can effectively avoid because the throughput that crushing equipment's life cycle caused descends, when the mineral aggregate can't in time carry out the broken condition, leads to the flash accident that spills over from feed hopper, realizes band conveyer automatic protection.
