Abstract

PURPOSE:To prevent the clogging and wearing damage of a chute by a method wherein the chute is formed by forming a plurality of wire ropes arranged in parallel with a pallet in the widthwise direction at a predetermined interval from the upper end to the lower and so as to obtain the shape of a screen through a plurality of guide liners. CONSTITUTION:A chute 8 is formed of a plurality of wire ropes 10, arranged in parallel with a pallet in the widthwise direction at a predetermined interval from the upper end toward the lower end, and a plurality of guide liners 12, having a bush 13 at a penetrating part supporting the wire rope 10, so as to have the shape of a screen. The wire rope 10 is coated with urethane resin. On the other hand, the bush 13 of the guide liner 12 is formed of urethane resin. According to this method, the wire rope 10 is vibrated by the material dropped on the chute 8 while the adhesion and accumulation of the material are precluded by the vibration, whereby the wearing damage to the chute can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raw material supply device for a sintering machine for continuously producing sintered ore, calcined agglomerated ore and the like.

[0002]

2. Description of the Related Art Conventionally, as a raw material supply device for a sintering machine of this type, a raw material supply device for a sintering machine (hereinafter referred to as a raw material supply device) described in JP-A-5-1335 is known. This conventional raw material supply device has (1) a raw material supply mechanism for supplying a raw material to a pallet, and (2) its upper end is located in the vicinity of the raw material supply mechanism and its lower end is located above the pallet. A chute that is inclined at a predetermined angle in a direction opposite to the moving direction of the pallet, and (3) the chute is in the width direction of the pallet,
It is formed in a screen shape from a plurality of round steel bars and a guide liner which are arranged in parallel from the upper end to the lower end at a predetermined interval.

[0003]

In this conventional raw material feeding device, when the raw material carried by the raw material feeding mechanism falls onto the pallet through the chute, it adheres to and accumulates on the round steel bar, clogging the chute, and The round bar steel constituting the screen is worn and cut off, and the penetrating portion of the guide liner holding the round bar steel is worn and damaged. An object of the present invention is to provide a raw material supply device that does not have such a problem.

[0004]

A raw material supply device for a sintering machine according to the present invention includes a raw material supply mechanism 1 for supplying a raw material 2 to a pallet 5, and its upper end is located in the vicinity of the raw material supply mechanism 1. A chute 8 whose lower end is located above the pallet 5 and is inclined at a predetermined angle in a direction opposite to the moving direction of the pallet, and the chute 8 is the width direction of the pallet. In addition, a wire rope 10 coated with a plurality of urethane resins and arranged in parallel from the upper end to the lower end of the wire rope 10 at predetermined intervals, and a bush 13 of the urethane resin in a penetrating portion supporting the wire rope 10. It is a raw material supply device for a sintering machine, which is formed in a screen shape with a plurality of guide liners 12 included therein.

[0005]

In the present invention, since the flexible wire rope is used instead of the round steel bar forming the chute, when the raw material falls from the end of the raw material supply mechanism and hits the wire rope,
Since the wire rope vibrates and knocks off the raw material adhering to the wire rope, the adherence of the raw material to the wire rope,
No accumulation occurs. Therefore, there is no clogging of the shoot. Also, since the wire rope has a urethane resin coating layer on its surface, there is no wear cut. Further, since the guide liner supporting the wire rope has a bush of urethane resin in the penetrating portion, abrasion and damage of the penetrating portion do not occur.

Further, since the wire rope has a urethane resin coating layer on the surface and a urethane resin bushing in the penetrating portion of the guide liner, the sliding amount when the wire rope vibrates is reduced, and it is caused by friction. Wear is greatly reduced. Also, by limiting the diameter of the wire rope, the wire rope vibrates appropriately due to the impact when the raw material falls and collides, and the raw material adhering to the wire rope is peeled off, preventing the raw material from adhering to the wire rope and growing. At the same time, the wear resistance of the urethane resin coating layer is high, which significantly extends the life of the wire rope.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a schematic vertical sectional view of a raw material supply device for a sintering machine according to this embodiment. FIG. 3 is a schematic front view of the chute 8 of the raw material supply device for the sintering machine of this embodiment. FIG. 4 shows A- of FIG.
It is a line A arrow line view. The raw material 2 carried by the raw material supply mechanism 1 falls on the chute 8 at its end. The dropped raw material 2 is supplied to a pallet 5 that travels between the wire ropes 10 of a chute 8 having a screen shape according to the particle size and from the end to the bottom. At this time, since the wire rope 10 has flexibility, when the raw material hits it, it vibrates and the deposited raw material is wiped off.

As shown in FIG. 1, since the wire rope 10 is coated with urethane resin, it does not easily wear and is not cut. Further, since urethane resin is also highly flexible, it does not prevent the movement of the wire rope 10. Guide liner 12 that supports the wire rope 10
Since a bush 13 made of urethane resin is attached to the penetrating portion, fine vibration is absorbed by the guide liner bush 13 and the sliding amount when the wire rope 10 vibrates is reduced.

In this embodiment, the wire rope 10
Having a diameter of 6 mmφ and an outer diameter of the urethane resin coating layer 14 thereon of 14 mmφ, and a wire rope diameter of 4 mmφ having a urethane resin coating layer 14 thereon.
The outer diameter of 12 mmφ was used, but in each case, the raw material adhering to the wire rope 10 was peeled off, and the wire rope 10 was extremely worn. In this embodiment, the number of guide liners 12 is 2, and the distance between them is 1200 m.
It was m.

That is, when the conventional round steel bar having an outer diameter of 12 mmφ was incorporated into the guide liner without the guide liner bush, the life of the round steel bar was only about one week, but in the case of this embodiment, it was 16 weeks. there were.

EFFECTS OF THE INVENTION By using the raw material supply device of the present invention, the raw material adhering to the wire rope is peeled off, a stable sintering raw material is supplied, and the life of the wire rope is greatly extended.
