Description

Raw Material Storage Hopper Assembly

The present invention relates to a hopper for temporarily storing the raw material used in the converter, a steelmaking facility, and more particularly, to a moving raw material storage hopper assembly useful for using a small amount of a plurality of raw materials.

In the converter, which is a steelmaking facility for refining molten iron with molten steel, the flux input into the converter furnace is converted into a converter hopper (storage hopper) 1a (1b) using a belt conveyor (4) system from the ground hopper (1). After storing temporarily in the), the basis weight is added to the basis weight hopper (5) as much as the amount to be injected during the blowing operation.

In the related art, the subsidiary materials transported by the raw material transport flow as shown in Fig. 1 are introduced into the converter furnace by the operation of the apparatus as shown in Fig. 2, and the conventional storage hoppers 1a and 1b In this case, one basis weight hopper 5a, 5b is connected to one fixed storage hopper 5a, 5b, respectively, and raw materials are stored and used in basis weight.

However, the fixed storage hopper (1a) (1b) as in the prior art is not suitable for the recent situation in which new raw materials are continuously developed and used due to the increasing recycling of waste and development of raw material development technology, This causes the inconvenience of installing a new storage hopper and a basis weight hopper each time, or emptying the used storage hopper and the basis weight hopper and refilling new raw materials.

For example, if a special purpose raw material has to be put in during the converter work, the existing storage hopper is limited and is already filled with other raw materials. It is inconvenient to use secondary raw materials, and these storage hoppers have the advantage that they can be used in a state of storing a large amount of raw materials at a large time while the storage hopper reacts with air when the storage hopper is not used for a certain time. It was caused by the change in the raw material components due to the quality deterioration, whereby a situation that a small amount of raw materials to be used by the operator had a problem that the manual input.

The present invention has been devised to solve such a conventional problem, and its purpose is to provide a plurality of raw material storage hoppers for temporarily storing side materials on the converter furnace so that only necessary materials can be added to the basis weight hopper. The present invention provides a moved raw material storage hopper assembly.

The present invention as a technical configuration for achieving the above object,

In the hopper assembly is installed in the storage hopper having a basis weight function connected to the secondary raw material input pipe connected to the converter, and temporarily storing the secondary raw material supplied to the storage hopper,

Install a rail passing through the upper portion of the storage hopper,

A plurality of hoppers moving along the rail is integrated by the connecting rod,

The connecting rod is powered by a cylinder,

The position of the hopper is by providing a moving raw material storage hopper assembly, characterized in that it is sensed by a plurality of limit switches.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is an overall configuration showing a state in which the raw material is put into the converter having a raw material storage hopper assembly according to the present invention, the secondary raw material input pipe (8a) (8b) connected to the raw material to the top of the converter A plurality of basis weight hoppers 5a and 5b for discharging the basis weight raw materials are shown. Of course, the raw material weighed by the basis weight hoppers 5a and 5b is supplied to the feedstock input pipes 8a and 8b through the feeder boxes 7a and 7b by the lower feeders 6a and 6b. .

A rail 51 horizontally provided in the longitudinal direction passing through the upper portions of the basis weight hoppers 5a and 5b is provided, and the rail 51 has a plurality of hoppers 46a, 46b, 46c, 46d and 46e. ) And the hoppers 46a, 46b, 46c, 46d, 46e are connected and fixed to each other so as to be integrally operated by the connecting rod 41, and the connecting rod 41 Plural wheels 42 are mounted on the rails 51 and the wheels 42 are mounted on the rails 51 so that the hoppers 46a, 46b, 46c, 46d, 46e are integrated along the rails 51. To be able to act. Of course, the rail 51 is fixed to the installation frame and the like by the support (44).

The connecting rod 41 is powered by the cylinder 40 so that it can move along the rail 51, and 45 and 50 are hydraulic tank and hydraulic pressure that can supply hydraulic pressure to the cylinder 40 Point the motor.

In addition, the limit striker 48 is provided at any one of a proper portion or the hopper of the connecting table 41, and the limit striker 48 has a plurality of limit switches 43a provided in the longitudinal direction of the rail 51. By operating the (43b) 43c, it is possible to determine where the hoppers 46a, 46b, 46c are located. These limit switches 43a, 43b, 43c are used as the transducers 12, By providing a signal to the control device 13 and the operation panel 14, the cylinder 40 and the like are automatically operated by pre-programmed programming.

Of course, each of the hoppers 46a, 46b, 46c, 46d, 46e has a feeder box 47a, 47b, 47c, 47d, 47e and feeder 53a, 53b on the lower side. 53c, 53d, and 53e.

The device of the present invention having the above-described configuration is equipped with a plurality of hoppers 46a, 46b, 46c, 46d, 46e and waits for work in the state of receiving different sub-materials, for example, stored in the hopper 46c. In order to inject the subsidiary materials, the hopper 46c may be moved to the upper portion of any one of the storage hoppers 5a and 5b connected to the converter.

If the sub-material of the hopper 46c is controlled to be weighed to the left hopper 5a through the operation panel 14, the control device 13 operates the hydraulic motor 50 to move the cylinder 40 forward or backward. Whereby the basis weight hoppers 46a, 46b, 46c, 46d, 46e move along the rail 51, and thus the basis weight hoppers are detected by the detection signals of the limit switches 43a, 43b, 43c. It can be determined whether 46c is located above the storage hopper 5a. Of course, this determination is made by programming input in advance according to the arrangement of the limit switches 43a, 43b, 43c, and simply sets the limit switch corresponding to the left hopper 5a in the basis weight hopper 46a ( As many as 46b), 46c, 46d, 46e, and limit switches corresponding to the right hopper 5b, may be installed as many as the basis weight hoppers 46a, 46b, 46c, 46d, 46e. have.

In any case, when it is determined by the detection values of the limit switches 43a, 43b and 43c that the basis weight hopper 46c is positioned on the storage hopper 5a, the operation of the cylinder 40 is stopped and the position It is maintained, and the subsidiary basis work begins. That is, the sub-material discharged from the basis weight hopper 46c and dropped into the storage hopper 5a changes the signal value of the load cell 15a mounted on the storage hopper 5a and is stored by the signal value of the load cell 15a. When the appropriate amount of sub-material is basis weighted in the hopper 5a, the sub-material discharge from the basis weight hopper 46c is terminated.

Of course, the storage hopper 5a will continue the post process of inputting the basis weight of subsidiary materials to the converter.

In addition, various methods for subsidiary material input may be derived by arranging the plurality of basis weight hoppers 46a, 46b, 46c, 46d, 46e, for example, as shown in FIG. The basis weight hoppers 46b and 46e correspond to each of the 5a) and the right storage hoppers 5b so that separate sub-materials may be added to the left and right storage hoppers 5a and 5b, respectively.

As described above, according to the moving raw material storage hopper assembly according to the present invention, by installing a plurality of basis weight hopper to move along the plurality of storage hopper upper path, it is possible to supply various types of sub-materials to the converter as needed.
