Automatic sealing device for coke feeder

Abstract

The invention relates to an automatic sealing device for a coke feeder, which comprises a seat board type disc valve, wherein the seat board type disc valve comprises a valve body, a valve plate, a sealing ring and a hydraulic cylinder; the valve body is vertically arranged on the coke feeder; the upper end of the valve body is provided with the hydraulic cylinder; the valve plate positioned in the valve body is connected to the end tip of the piston rod of the hydraulic cylinder; and the sealing ring is installed on the inner wall of the valve body, and is positioned at the tail end of the stroke of the valve plate. According to the automatic sealing device disclosed by the invention, the safe and stable operation of the coke feeder of the coal gasifier is guaranteed, and only the sealing ring needs to be changed in the maintenance and exchange period, and therefore the work load is reduced.

Description

technical field [0001] The invention relates to a sealing device, in particular to a sealing device for a coking machine in the chemical industry. Background technique [0002] In the current situation of rising coal prices, most ammonia synthesis enterprises using coal as raw materials use artificially manufactured briquettes as raw materials. The flap-type disc-sealed automatic coking machine used in fixed-bed gas furnaces in the chemical industry is an important part of coal gasification. Equipment, after using the coking machine in the gas furnace, it has played a great role in stabilizing the furnace condition, increasing the gas output of a single furnace and reducing the labor intensity. However, due to the unreasonable structure of the coking machine and the reasons of management, operation, and maintenance, etc., there are often gas leakage, carbon leakage, gas leakage, and liquid leakage, which seriously affect production. During the operation of the gas furnace, ...

AI Technical Summary

Problems solved by technology

However, due to the unreasonable structure of the coking machine and the reasons of management, operation, and maintenance, etc., there are often gas leakage, carbon leakage, gas leakage, and liquid leakage, which seriously affect production.

During the operation of the gas furnace, the disc valve of the coking machine operates more than 1,000 times a day. Because the briquettes are easily broken and the dust is large, it is easy to form coal sludge on the flap disc valve, which affects the sealing effect of the coking machine. Gas leakage, leading to safety hazards of gas poisoning and huge waste of effective gas loss
