Double-hopper loading device with automatic discharge turnover plates and seal gates and working method

Abstract

The invention relates to a double-hopper loading device with automatic discharge turnover plates and seal gates and a working method thereof. The device comprises charging units, a dust collecting cover, a fixed hopper and a dust collecting pipeline. The dust collecting cover is connected to the fixed hopper, and the number of the charging units is two, each charging unit is composed of a trolley,an upper movable hopper, a lower movable hopper, a seal gate, a charging bell, a water seal cover and a manual trolley movement mechanism. Specifically, the upper movable hopper is connected to the fixed hopper through a flexible connection sleeve, and the fixed hopper is internally provided with a sealed cross beam and turnover plates, and the seal gate is disposed between the upper movable hopper and the lower movable hopper. The upper movable hopper and the lower movable hopper are internally equipped with the charging bell, and the bottom of the lower movable hopper is provided with the water seal cover. The device provided by the invention can satisfy the charging and distribution requirements of continuous and few distributed feeding within a long time, is equipped with two independent charging units, each of which realizes pre-storage and double-sealing functions by the seal gates and turnover plates, and ensures the continuity of production operation.

Description

Technical field [0001] The invention relates to a dry quenching furnace loading device, in particular to a double hopper loading device with an automatic discharge flap and a sealing gate 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. The loading device for conventional CDQ is as figure 1 As shown, it is installed on the top platform 1-1 of the dry quenching furnace, and is mainly composed of hopper 1-2, dust cover 1-3, 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. [0003] Hopper 1-2 is installed on hopper trolley 1-6, furnace cover 1-5 is installed on furnace cover trolley 1-7, fu...

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
