Description

Adjustable dry quenching loading device

Technical Field

The utility model relates to a coke dry quenching auxiliary device, in particular to a coke dry quenching adjustable loading device which can adjust the falling speed of red coke in the process of loading red coke in a coke dry quenching system.

Background

The coke dry quenching loading device is an auxiliary device used for loading red coke in the coke dry quenching treatment process so as to facilitate the red coke to better enter a coke dry quenching furnace, and is widely used in the coke dry quenching field; the dry quenching charging device is positioned at the top of the dry quenching furnace of the dry quenching device and is used for charging red coke carried by a crane into the dry quenching furnace. Its main function lies in: on one hand, opening and closing the furnace cover according to instructions and charging red coke into a dry quenching furnace through a charging hopper; on the other hand, the dust and the flue gas generated in the loading process are guided into a dry quenching dust removal system for dust removal through a dust and gas collecting pipeline. It has two functions, opening and closing the furnace cover according to instructions and charging red coke into the dry quenching furnace through a charging hopper. Conventional coke dry quenching charging devices are disclosed in patent documents with publication numbers CN203187619U and CN 205616840U, CN202322722UThe technical scheme is that the loading device is arranged on a platform at the top of the dry quenching furnace and mainly comprises an upper coke receiving hopper, a lower distributing hopper funnel, a bell, a movable trolley, a furnace cover, a driving device, a water sealing cover, a movable dust collecting pipeline and the like which are arranged in the lower distributing hopper. A driving device on the driving device drives a furnace cover on the movable trolley, an upper coke receiving hopper and a lower distributing hopper to travel along the track, so that the furnace cover is opened sequentially, and the hopper is aligned to a dry quenching furnace opening; or the hopper is moved away from the dry quenching furnace mouth, and the furnace cover is closed. When in standby, the furnace cover is buckled on the dry quenching furnace mouth, and the water seal cover on the furnace cover is inserted into the water seal groove of the furnace mouth to keep the dry quenching furnace mouth sealed. When the hoister sends a red coke loading command, the driving device of the driving device starts traction action, the furnace cover is lifted at a low speed, and the whole mobile trolley starts to travel at a normal speed under the condition that the furnace cover is lifted until the discharge opening of the hopper of the loading device on the mobile trolley is aligned with the dry quenching furnace opening. And the movable trolley moves at a low speed at the final stage of the moving stroke of the movable trolley, and the water seal cover arranged at the lower hopper of the loading device falls into the water seal groove at a low speed to prevent dust at the dry quenching furnace mouth from escaping outwards during loading. When the loading device starts to act to open the furnace cover, the wear-resistant butterfly valve on the movable dust collecting pipeline is also automatically opened to start collecting dust, and the raised dust produced in the current loading process is mainly in the coke loading process and the furnace cover opening process. As also disclosed in the patent documents with the application number 201811439229.X and the publication number 109280558, although the technical proposal solves most of smoke generation in the process of covering the furnace cover to a certain extent, the primary coke discharging amount is 19 to 45 tons (namely the volume is 65 to 105 m) according to the size of the coke oven³) For example, the single-hole yield of the 4.3 m coke oven is 19 tons (namely the volume is 44 m)³) The single-hole yield of the 5.5 m tamping coke oven is 32 tons (namely the volume is 74 m)³) The single-hole yield of the 6.25 m coke oven is 33 tons (namely the volume is 76 m)³) The single-hole yield of the 7.63 m coke oven is 44 tons (i.e. the volume is 105 m)³) Because the coke dry quenching furnace is filled with 19 to 45 tons of red coke (i.e. the volume is 44 to 105 m)³) Meanwhile, as the domestic coke oven is enlarged, the coke oven with 4.3 meters is eliminated, so the coke loading in the dry quenching furnace is increased at one time, and the coke loading is about in an effective prestorage chamber of the dry quenching furnaceAfter the red coke is filled in the coke oven within 30-45 seconds, the coke loading amount is smaller after the beginning and the end of a period, the red coke is filled in the coke oven actually and 19-45 tons (the volume is 65-105 m) of red coke are filled in the coke oven within 15-20 seconds³) The coke is instantly loaded into a dry quenching furnace, and the pressure in the dry quenching furnace can not be released when the middle section of the coke loading process stays at the necking part of a lower cone hopper and an upper cone hopper of a loading device for about 10-20 seconds, so that the heat wave and the furnace volume generated when a large amount of red coke enters the dry quenching furnace for an instant time are suddenly changed, the pressure in a pre-storage chamber is suddenly increased, the red coke heat wave at 1000 ℃ and the air entering the dry quenching furnace during the opening of the furnace generate great changes to the airflow and the pressure in the dry quenching furnace, the airflow generates turbulence and pressure fusion, the airflow in the dry quenching furnace generates turbulence and the pressure is increased to be released when the furnace cover is covered by a refractory brick, the smoke is generated when the furnace cover is covered, the fire phenomenon is generated seriously, the impact is simultaneously caused to the refractory brick in the dry quenching furnace, the service life of the dry quenching furnace is seriously influenced, and the dry quenching furnace is mainly composed of the refractory brick, the environmental standard index is also seriously influenced, and at present, a unit also adopts the descent speed of the hoister to slow down and prolong the red coke charging time, but the production yield of the coke oven is seriously restricted, for example, the coke oven is generally 150 holes for discharging coke (namely 150 times for charging coke) 120-fold, 30 seconds are prolonged each time, 60-75 minutes are required to be prolonged each day, and the equipment maintenance time of each day is seriously compressed or the equipment maintenance time of each day is required to be directly cancelled.
