Abstract

PROBLEM TO BE SOLVED: To provide a zinc refined slag shipping method that can make zinc refined slag shipping work efficient, remarkably improve work environment without the rise of dust and remarkably reduce the labor of workers. SOLUTION: In this zinc refined slag shipping method, zinc refined slag is thrown into a transport hopper 7 placed on a deck of a moor truck 17, and after moving the transport hopper 7 to a quay by the motor truck 17, the transport hopper 7 is lifted by an unloader, and a cover part provided at the bottom part of the transport hopper 7 is opened above a ship 16 to convey the zinc refined slag into the ship 16. The transport hopper 7 used in this case is so constituted that the bottom part of the transport hopper 7 is composed of two cover parts laterally opened/closed around support points provided at the lower part side walls of the transport hopper 7 and that the bottom part can be laterally opened/closed by the expanding/contracting action of two power cylinders fitted to both sides of a middle stage part of the transport hopper 7.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for extracting zinc smelting slag discharged from a zinc smelting process from a storage warehouse and loading the same by using a transport hopper.

[0002]

2. Description of the Related Art Conventionally, when zinc smelting slag is taken out of a warehouse and loaded, as shown in FIG.
Into the driving hopper 12 and the loading loader 14 by the extraction conveyor 13 provided at the bottom of the driving hopper.
It was thrown into the ship 16 by the boom conveyor 15.

[0003]

In such a method,
To prevent the smelting slag from getting entangled in the conveyor belt such as the extraction conveyor, loading loader, and boom conveyor, the conveyor belt inspector should be assigned at all times during the transportation operation, and the conveyor belt should be stopped immediately if the conveyor belt idles. It was necessary to perform cleaning and restart the operation of the transport belt. For this reason, there has been a problem that a heavy labor load is imposed on the transport belt inspector, and a dangerous operation such as being caught in the transport belt is required. In addition, since the smelting slag is fed into the transport ship by the transport belt, particularly in an empty state, the step between the loading portion of the transport belt and the bottom level is large, and there is a problem in the working environment due to dust. An object of the present invention is to provide a zinc smelting slag loading method that solves the above problems.

[0004]

Therefore, according to the present invention, zinc refining slag is put into a transport hopper placed on a truck bed, the transport hopper is moved to the quay by the truck, and then the unloader is moved by the unloader. A zinc smelting slag loading method characterized by lifting a transport hopper, opening a lid provided at the bottom of the transport hopper above a ship, and carrying zinc smelting slag into the ship. Further, the present invention also provides a bottom portion of the transport hopper constituted by two lid portions which can open and close around a fulcrum provided on a lower side wall of the transport hopper, and two lids attached to both sides of a middle portion of the transport hopper. The above-mentioned method for loading zinc smelting slag is characterized by using a transport hopper capable of opening and closing the bottom part left and right by the expansion and contraction operation of the power cylinder.

[0005]

FIG. 2 shows an embodiment of the present invention. The zinc smelting slag is put into the transport hopper placed on the truck bed, and after moving the zinc slag to the quay, the transport hopper is lifted by the unloader, and the lid provided at the bottom of the transport hopper is opened above the ship. To carry zinc smelting slag. Also,
FIG. 3 is an overall view of a transport hopper used in the present invention, and FIG. 4 is a bottom open / close lid of the transport hopper. As shown in this figure, the transport hopper 7 is hung on the unloader 5 by the chain 8 and the wire 4. The two lids 2 attached to the fulcrum 3 provided on the lower wall of the transport hopper 7 are opened and closed left and right by two power cylinders 1 also provided at the middle part of the transport hopper 7.

[0006]

Next, the operation will be described. As described above, by using the transport hopper of the present invention, the height of the transport hopper is adjusted according to the loading status of zinc smelting slag on the ship, and the bottom of the transport hopper is opened by remote control to load the ship. Since the lowering can be performed, there is no dust and the working environment is remarkably improved. Further, the labor of the worker is remarkably reduced.

[0007]

As described above, according to the present invention,
The zinc smelting slag loading operation can be performed efficiently. Further, there is no dust, and the working environment is remarkably improved. Further, the labor of the worker is remarkably reduced.
