Description

Feeding device for smelting furnace capable of automatically discharging

Technical Field

The invention relates to the technical field of metallurgical equipment, in particular to a feeding device capable of automatically discharging materials for a smelting furnace.

Background

In the operation of electric stove iron and steel smelting, it is reinforced from the top of smelting furnace through the basket, and traditional basket is reinforced to have two kinds of modes: one is to pour the material through overturning, need drive unit and drive unit of the auxiliary overturning, its structure is complicated, the cost is higher; the other is to discharge from the bottom of the material basket, a corresponding electric valve opening device is required to be arranged, when the size of the material basket is larger, the gravity load borne by the electric valve opening device is higher, so that the requirement cannot be met, the size of the material basket is generally smaller, the feeding times are increased, and the heat loss generated by feeding and opening a furnace cover is increased.

Disclosure of Invention

The invention aims to solve the problems in the prior art and provides a feeding device for a smelting furnace, which can automatically discharge materials.

The specific scheme of the invention is as follows: the utility model provides a feeding device that is used for smelting furnace can automatic blowing, which comprises a basket body, basket body top and bottom are equipped with the opening, two gudgeons are equipped with to the symmetry on the basket body, the base is equipped with to the basket body bottom, the base can be opened or close, two lugs are equipped with to base both sides upper end symmetry, the base divide into a left side along the center, right two halves, wherein two left seat connecting plates are equipped with to left half top edge symmetry, two right seat connecting plates are equipped with to right half top edge symmetry, both ends respectively weld two round pins around on the basket body, left seat connecting plate and right seat connecting plate are articulated with the round pin axle respectively, the horizontal distance that round pin axle and base divide between the half is less than the horizontal distance between round pin axle and the base lug, it has a connecting rod to lie in.

The outer wall of the basket body is provided with a support extending outwards, the support is provided with a hanging ring, the hanging ring is connected with two chains, and the two chains are respectively connected with two lifting lugs of the base.

The working principle of the invention is as follows: the method comprises the following steps of filling raw material steel into a basket body, lifting the basket body to the top of a smelting furnace through two trunnions of the basket body by a main hook of an overhead traveling crane, connecting a base with the basket body through four pin shafts on the basket body, and enabling the left part and the right part of the base to be opened and closed in a rotating mode by taking the pin shafts as circle centers; the auxiliary hook of the crown block upwards pulls the lifting ring to drive the two chains to enable the edge of the base to be pulled upwards, and the base is rotated to two sides to be opened, so that discharging is achieved.

Compared with the prior art, the invention has the following advantages: the connecting part of the base and the basket body is designed into a self-locking structure, the base is tightly pressed by the gravity of the raw material steel to ensure that the leakage is avoided, the automatic discharging device can be made into a larger size, dozens of tons of materials can be fed at one time, and the material door is opened by using the auxiliary hook of the overhead travelling crane to automatically discharge the materials.
