The coke is an indispensable raw material in the production process of blast furnace iron making, mainly plays roles in framework, carbon supply, reduction, heat supply and the like, and plays a vital role in whether the blast furnace is normally produced or not. At present, single coal is reasonably distributed, mixed and crushed mainly through a coal preparation process in coke production, and then the single coal is sent to a coke oven carbonization chamber for high-temperature coking. After the coke produced by the coke oven is screened and detected, the qualified coke is sent to a blast furnace to be used as a raw material for production.
Before being conveyed to an iron-making process, coke needs to be screened and classified through a coke screening building so as to meet the requirement of the grain size of blast furnace production. The screened coke needs to enter a coke storage bin through a chute so as to realize the production continuity of the coke oven and the blast furnace. However, the conventional coke chute of the conventional design is in a mode of external steel plates and internal ceramic tiles, and coke passes through the bar screen and then impacts the ceramic tiles in the chute to enter the coke bin. Because the coke has high hardness and large impact force, the lining ceramic tiles are broken and fall off frequently, the chute is blocked frequently, the treatment time is 30min for short time and 60min for long time, the production is interrupted frequently, and the production plan is difficult to meet.
Meanwhile, after the chute is blocked, the problem that the water content fluctuation of the dry quenching is large, the stability of the operation of the blast furnace is seriously influenced and the production of molten iron and a subsequent procedure is extremely disadvantageously restricted must be solved by adopting a water flushing mode.
Disclosure of Invention
The utility model aims at providing a novel sieve burnt building chute to above-mentioned condition, this sieve burnt building chute's use makes the operation continuity of sieve burnt building obtain effective assurance, and coke oven and blast furnace production stability are showing and are improving.
The utility model has the following concrete scheme: a novel chute for a coke screening building is provided with a chute body which is obliquely arranged, guardrail coamings are arranged on two sides of the chute body, the chute body is formed by sequentially obliquely splicing a plurality of wear-resistant lining plates, the joint edges of two adjacent wear-resistant lining plates are spliced in an aligning and splicing mode, the interfaces of the two wear-resistant lining plates are kept parallel and level, and the upper edge of the wear-resistant lining plate with a low position is not higher than the lower edge of the wear-resistant lining plate with a high position; the splicing positions of two adjacent wear-resistant lining plates are connected into a whole by fastening screws, and each wear-resistant lining plate is connected with a corresponding bracket for mounting the chute body.
Further, the utility model discloses in correspond each fastening screw and all be equipped with the screw backplate that an oblique downward set up on wear-resisting welt, the screw backplate is close to the installation of guardrail bounding wall to the screw backplate on both sides all is the splayed and arranges.
Further, in the utility model discloses in wear-resisting welt adopts wear-resisting steel sheet preparation to form.
The utility model discloses a method that the wear-resisting welt that adopts novel wear-resisting steel sheet preparation replaces conventional ceramic tile as sieve coke building chute welt is showing the fault rate and the breakage rate that have reduced the chute, has stabilized the moisture and the production continuity of coke, has ensured the steady operation of coke oven and blast furnace effectively.

Detailed Description
Referring to fig. 2-4, the utility model relates to a novel coke screening floor chute, which is provided with a chute body 7 arranged obliquely, wherein the two sides of the chute body are provided with guardrail coamings 2, the chute body is formed by sequentially obliquely splicing a plurality of wear-resistant lining plates 5, the joint edges of two adjacent wear-resistant lining plates adopt an alignment splicing mode, the interfaces of the two wear-resistant lining plates are kept parallel and level, and the upper edge of the wear-resistant lining plate with a low position is not higher than the lower edge of the wear-resistant lining plate with a high position; the splicing positions of two adjacent wear-resistant lining plates are connected into a whole by fastening screws 3, and each wear-resistant lining plate is connected with a corresponding bracket for mounting the chute body.
Further, correspond each fastening screw in this embodiment and all be equipped with a screw backplate 4 that sets up to one side down on wear-resisting welt, the screw backplate is close to the installation of guardrail bounding wall to the screw backplate on both sides all is the splayed arrangement of falling.
The design of screw backplate under the prerequisite that does not influence the coke and descend, has protected screw or bolt that are used for the fastening and has avoided the coke to strike the condition that appears becoming flexible or damaging for wear-resisting welt is fixed more firmly, uses more lastingly.
Further, in this embodiment both wear-resisting welt and guardrail bounding wall all adopt wear-resisting steel sheet preparation to form, increase its life cycle.
The utility model discloses an installation preparation as follows:
