Red-hot coke receiving device

Abstract

To provide a red-hot coke receiving device which can receive red-hot coke while mounting a conveyance bucket on a bucket truck and turning only the conveyance bucket, and is applicable even to a small coke furnace. [MEANS FOR SOLVING PROBLEMS] The red-hot coke receiving device comprises a coke conveyance bucket (13) equipped with a discharge gate (11) in the bottom and having a conical portion (12) on the underside, and a suspension frame mechanism (15) equipped with an outer frame section (14) surrounding the conical portion (12) of the conveyance bucket (13), a hoist function of the conveyance bucket (13) and an open / close function of the discharge gate (11) of the conveyance bucket (13). When a bucket is hoisted, the discharge gate (11) abuts against the lower surface of the conical portion (12) to lift the conveyance bucket (13), and, when it is mounted on a bucket truck (44), the outer frame section (14) lowers and a suspension roller (40) secured to the outer frame section (14) separates from the recess (39) of door hook member (38) so that the conveyance bucket (13) can be rotary driven independently of the suspension frame mechanism (15). The outer frame section (14) of the suspension frame mechanism (15) located on the opposite sides of the frame mechanism (13) is contained in the conical portion (12).

Description

technical field [0001] The invention relates to a red-hot coke receiving device for receiving red-hot coke from a coke oven and transporting it to coke dry fire extinguishing equipment. Background technique [0002] Conventionally, in order to receive the red-hot coke discharged from the coke furnace, transport it, and load it into the coke dry fire extinguishing equipment, a red-hot coke receiver equipped with a cylindrical conveyor bucket that can be lifted by a lifting frame mechanism has been used. device (for example, refer to Patent Document 1). In this red-hot coke receiving device, since the conveying bucket and the lifting frame mechanism are placed on the turntable of the bucket trolley, the red-hot coke discharged from the coke oven can be received while turning the conveying bucket by rotating the turntable. Hot coke, therefore, is able to receive coke evenly in the conveyor hopper, which is characterized by improved coke volumetric efficiency and reduced weight...

AI Technical Summary

Problems solved by technology

[0005] However, in the red-hot coke receiving device described in Patent Document 1, if the transfer bucket and the lifting frame mechanism are rotated together, there is a problem that the required turning radius is increased compared with the case of rotating the transfer bucket independently. Large, it is necessary to increase the receiving space of the bucket in front of the coke oven, and at the same time increase the driving power required for the rotation. When making coke, only the conveyor bucket can be rotated, and the lifting frame mechanism is divided into two, and the bucket is lifted from both sides, but since the lifting frame mechanism is divided into two, it has the strength as a lifting frame mechanism Falling, and it is difficult to hold the conveyor bucket stably

For this reason, although the structure in which the outer frame of the conveyor bucket is held by four lifting rollers on the lifting frame mechanism, and the conveyor bucket and the outer frame can be separated during rotation, it is necessary to use the outer peripheral side of the conveyor bucket. In the space where the outer frame is arranged, if the width of the coke receiving space in front of the coke oven is narrow and the height is low, such as a small coke oven, the outer frame interferes with the outer wall of the coke oven, and it cannot be used on the outer peripheral side. The problem of the conveyor bucket with the lifting frame mechanism of the outer frame part
