Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a device for supplying mud to the mud inlet of a mud gun for closing the tap hole of a blast furnace.

(Prior Art) Usually, a mud gun 19 shown in FIG. 5 having a mud inlet 20 is used to close the tap hole 21 of a blast furnace. The conventional automatic muzzle supply device for this muzzle gun includes a portable muzzle cutting device, a muzzle setting pallet, a muzzle extrusion device, and a muzzle transport conveyor.
It is based on a portable feeding device such as that shown in Japanese Patent No. 47726. However, since both are installed near the narrow tap hole, they occupy a considerable amount of space when evacuation of the equipment is taken into account. In addition, the vicinity of the taphole is in an adverse environment with dust and high heat, which poses many problems in terms of effective use of space, maintenance of equipment, and ensuring safety during work. Furthermore, there were other drawbacks such as increased costs due to the large size of the equipment.

(Problems to be solved by the invention) This invention was made based on the above-mentioned circumstances, and aims to effectively utilize the space near the taphole, improve the maintainability of equipment, and ensure work safety. The purpose is to The company also aims to reduce costs by downsizing the equipment and save labor in adding matzo.

(Means for Solving the Problems) The basic features of the present invention are a removable pallet consisting of multiple rows of groove formwork with longitudinal slots at the bottom, and a block-shaped pallet set in the groove formwork. A conveyor for conveying the blast furnace mud to the mud inlet of the mud gun, a pushing jig provided for each groove form to push the mud onto the conveyor, and moving the jig through the narrow gap. It has a table on which the main unit consisting of the pallet, the conveyor, the extrusion jig, and the drive unit is mounted, and when it is not needed, the conveyor is stored in the main body and is attached to the table. It has the ability to be stored under the cast bed using an elevating device.

(Example), (Operation) A specific example of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the main body of the mat supply device,
This main body is mounted on a table 2, and can be raised above the casting bed using a lifting device 3 when necessary, and lowered and stored under the floor when unnecessary.

The main body 1 consists of a removable pallet 5 on which a block-shaped blast furnace mud 4 is set, a mud extrusion jig 7 mounted on a pedestal 6 and its drive device 8, and a mat extrusion device 8 for transporting the extruded mud to a mud inlet 20 of a mud gun 19. Two conveyor belts 9, 1
0 as the basic component.

The pallet 5 has a plurality of rows of groove forms 12 made up of partition plates 11 inside, and when the main body is attached, the metal fittings 13 serve as guides for positioning the pedestal 6 and the metal fittings 14 serve as guides for positioning the top cover 17, which will be described later. At the same time, the structure increases the rigidity of the pallet. Block-shaped mats 4 are regularly arranged in each groove frame at a mat factory or the like. The pallet 5 on which the mats 4 have been set is transported to this device by a crane or the like and replaced with an empty pallet 5. By doing this, the mat 4 is replenished. A slot 15 is provided in the bottom of each channel form 12 in the pallet 5 in the longitudinal direction. This narrow gap 15 has a width that allows the mat extrusion jig 7 driven by the drive device 8 to pass through.

The drive device 8 moves the extrusion jig 7 into the narrow gap 15.
Through this, the mats 4 set in the groove formwork 12 can be pushed out one by one at an appropriate speed. This mat extrusion jig 7 and its driving device 8 are provided for each groove form 12, and it is possible to extrude each groove form 12 singly or in multiple rows at the same time. After the extrusion is completed, the jig 7 is moved back to the initial position by the driving device 8.

The mat 4 pushed out from the groove formwork 12 is transferred onto a belt conveyor 9 fixed in front of the pallet 5. The matsudo 4 conveyed by the same belt conveyor 9 is transferred to the next stage belt conveyor 10,
After being transported to the muzzle inlet 20 of the muzzle gun 19, it is inserted. The belt conveyor 10 can be moved back and forth by a drive device 16. Therefore, the head of the conveyor can be advanced until it reaches the mound inlet 20 when mounds are introduced, and when unnecessary, it can be moved back and housed in the main body.

A part of the mats 4 of the groove formwork 12 is directly transferred to the belt conveyor 10 without passing through the belt conveyor 9. With this mechanism and the storage function of the conveyor described above, the main body 1 can be made smaller, and the opening area of the floor for storage under the floor can also be made smaller.

A removable top lid 17 is placed on the main body 1. This top cover has almost the same shape and area as the projected image of the main body, and when stored, it closes the opening in the floor, forming a work deck and at the same time preventing accidents from falling. In addition, there is a safety shelf 18 in the middle of the lifting device.
is provided so that it is positioned above the casting bed when the main body is raised, and is designed to prevent accidents from falling into the floor opening. Also, consider installing the lifting device on a movable platform.

(Effects of the invention) As described above, according to the invention, the feeding device can be stored under the cast bed where it is less affected by dust, high heat, etc., so the space near the taphole can be used effectively and the equipment It is also possible to improve maintainability and ensure operational safety. Furthermore, miniaturization of the device also has the effect of reducing costs.
