Description
Technical Field
The utility model relates to a belt feeding powder lump breaker belongs to blast furnace smelting technical field.
Background
At present, in the process of preparing materials for blast furnace ore tank pellets and lump ore bins in blast furnace smelting production, the materials in a blast furnace tank discharging bin are screened by a vibrating screen and then arrive on a designed ore return belt along with a chute, and then arrive at a specified ore crushing recovery bin after running through a plurality of ore return belts and chutes, so as to wait for the discharge and shipment of the blast furnace ore crushing bin. The blast furnace raw materials are subjected to moisture, the quantity of the material powder of the raw materials, the surface of the chute is not smooth enough and the like, and the materials are accumulated on the chute frequently, so that massive mineral return is formed, and the chute is blocked and transported when the return ore is recovered and operated, so that the blast furnace cannot normally prepare materials. In order to ensure the normal material preparation of the blast furnace, the blast furnace needs to be subjected to air reduction and oxygen reduction to match with the blockage removal of the chute pipe under the chute, so that the yield loss is caused, and the production cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a belt material powder lump breaker is provided to above-mentioned prior art can hit the cubic on the garrulous belt, avoids blockking up and transports the elephant trunk, need not to the clear stifled of elephant trunk, and reduction in production cost guarantees that the blast furnace normally prepares material.
The utility model provides a technical scheme that above-mentioned problem adopted does: a belt feeding powder block crushing device comprises a conveying belt, wherein the conveying belt is arranged on a belt carrier roller, a fixed support is arranged above the conveying belt in a spanning mode, and the fixed support and the conveying direction of the conveying belt are arranged in a crossed mode; the fixed bolster bottom sets up the mounting bracket, the mounting bracket bottom symmetry is equipped with a plurality of even interval arrangement's impact unit, cubic material collision impact unit on the conveyer for cubic material is broken.
The conveying belt is a U-shaped structural member.
The impact unit respectively includes the connecting pipe, connecting pipe one end is fixed in the mounting bracket, and other end threaded connection impact bar, a plurality of impact bar's arrangement is the arc, with conveyer radian phase-match.
The mounting rack comprises two angle steels, the two angle steels are obliquely and crossly arranged, and a reinforcing plate is arranged between the two angle steels
Compared with the prior art, the utility model has the advantages of: a belt feeding powder block crushing device is characterized in that a conveying belt drives a block to be conveyed when running, and the running speed forms stable impact force, so that large blocks contact an impact rod and impact the impact rod, and the large blocks are crushed; the crushed blocks are conveyed to the next procedure, so that the blocking of the large blocks at the crushed ore transfer chute after the crushed ore caking is prevented, the blockage of the crushed ore transfer chute below the blast furnace groove is avoided, the stability below the blast furnace groove is ensured, and conditions are created for the smooth operation of the blast furnace.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the belt material powder lump crushing device in the embodiment includes a U-shaped conveying belt 2, and belt rollers 1 are symmetrically arranged at the bottom of the conveying belt 2. A fixed support 6 is arranged above the conveyor belt 2 in a spanning mode, and the fixed support 6 is arranged in a crossed mode with the conveying direction of the conveyor belt 2. The bottom of the fixed support 6 is provided with a V-shaped mounting frame 5, the bottom of the mounting frame 5 is symmetrically provided with a plurality of impact units which are evenly arranged at intervals, a large block-shaped material collides with the plurality of impact units in conveying, and the impact units impact the block-shaped material to ensure that the block-shaped material is broken.
The impact units respectively comprise connecting pipes 4, one ends of the connecting pipes 4 are fixed at the bottom of the mounting frame 5, and the other ends of the connecting pipes are in threaded connection with the impact rods 3. The arrangement of a plurality of impact bars 3 is arc-shaped and is matched with the radian of the conveying belt 2, so that the block materials on the conveying belt are impacted in all directions. The impact bar is a strip-shaped resin material.
The mounting frame 5 comprises two angle steels which are obliquely and crossly arranged to form a V-shaped structural member, and the reinforcing plate 7 is arranged between the two angle steels to improve the connection strength of the two angle steels.
Two ends of the fixed support are respectively welded on the conveying carrier roller support at the tail end of the ore crushing conveying belt, and two angle irons with proper sizes are welded in a crossed mode to serve as mounting frames of the impact bars. The bottom of the mounting rack is welded with a connecting pipe with internal threads, and the impact rod is connected to the connecting pipe in a threaded manner. The conveying belt drives the blocky materials to be conveyed when in operation, and stable impact force is formed at the operation speed, so that large blocky materials are contacted with the impact rod and are impacted with the impact rod, and then the large blocky materials are crushed; the crushed blocks are conveyed to the next procedure, so that the blocking of the large blocks at the crushed ore transfer chute after the crushed ore caking is prevented, the blockage of the crushed ore transfer chute below the blast furnace groove is avoided, the stability below the blast furnace groove is ensured, and conditions are created for the smooth operation of the blast furnace.
