Double-hopper charging device with double-side sealed hoisting sleeve and working method thereof

Abstract

The invention relates to a double-hopper charging device with a double-side sealed hoisting sleeve and a working method thereof. A charging platform is provided with two sets of charting units; in each charging unit, a discharging pipe and a hoisting sleeve are arranged at the bottom of an upper hopper; upper sealing mechanisms are arranged between the top of the discharging pipe and the top of the hoisting sleeve and arranged between the top of the hoisting sleeve and the upper hopper; lower sealing mechanisms are arranged between the bottom of the discharging pipe and the bottom of the hoisting sleeve and between the bottom of the hoisting sleeve and a lower hopper; upper and lower edges of the hoisting sleeve, a sealing body of a charging bell and a bell body are sealed through sealingsurfaces; a water sealing cover is arranged at the bottom of the lower hopper; the upper hopper is internally provided with a material level meter to be in interlocked control with an executing mechanism of the hoisting sleeve. According to the double-hopper charging device, charging and material distribution requirements of continuous and less dispersion type feeding within relatively long time can be met, and online standby application and rapid exchange of the charging bell are realized; the single charging unit has pre-storing and sealing functions, the discharging amount is easy to adjustand the sealing performance is good; the equipment cost and the operation cost are reduced.

Description

technical field [0001] The invention relates to a coke CDQ loading device, in particular to a double hopper loading device with double-side sealing of a lifting sleeve and a working method thereof. Background technique [0002] The charging device is an indispensable part of dry coke quenching. Its main function is to open and close the furnace cover, and evenly introduce the hot coke in the coke tank into the dry quenching furnace through the distributor for coke quenching. Conventional coke CDQ loading device such as figure 1 As shown, it is installed on the top platform 1-1 of CDQ furnace, and mainly consists of hopper 1-2, dustproof cover plate 1-3, material bell 1-4, furnace cover 1-5, hopper trolley 1-6, furnace Cover trolley 1-7, transmission mechanism 1-8, track frame 1-9, sliding support 1-10, fixed support 1-18 and guide template 1-11 etc. form. [0003] The hopper 1-2 is installed on the hopper trolley 1-6, the furnace cover 1-5 is installed on the furnace cover...

AI Technical Summary

Problems solved by technology

Because the loading device is not equipped with a pre-stored hopper, on the one hand, the continuous incoming materials for a long period of time make it impossible to switch between the furnace cover and the loading hopper during this period, which is equivalent to the CDQ furnace being in the state of opening the cover and charging. The internal pressure system will have adverse effects; on the other hand, when the dispersed feeding material with a small amount of material passes through the material bell, because the material cannot be layered, the ejection effect between the particles leads to a large randomness of the distribution, and it is difficult to achieve uniform distribution.

[0009] 2) The hopper of the loading device is only used as a circulation channel for materials during the loading operation, and does not have pre-storage and sealing functions

It is necessary to frequently use electric cylinders (or hydraulic cylinders, etc.) to switch the hopper and furnace cover to realize the loading or sealing of the furnace mouth, which increases equipment costs and operating costs

[0010] 3) The bell loaded into the hopper is easily damaged due to its long-term use under the conditions of strong wear and high temperature impact, and even if it is damaged as a whole, the work intensity is relatively high, and the operation takes a long time. Conventional maintenance time cannot meet the requirements, and it is difficult to ensure the continuity of production operations
