Anti fracture device for coke oven gas travel with rope displacement sensor

Release date: June 24, 2019 Hits: 135

There are the following problems in the process of heating and reversing in the coking gas pipe area of the coking plant of iron making company

1. Coke oven exhaust gas stroke or chain fracture: once the exhaust gas stroke or chain breaks down, some or all of the exhaust gas mounds (depending on the specific position of the stroke fracture) do not exchange air and waste gas, but the exhaust gas cylinder is still in normal operation. The limit stop connected to the cylinder rod joint of the exhaust gas cylinder still touches the forward (direction) limit of the exhaust gas travel, and sends a message No. 1 is transmitted to the reversing machine, which operates the gas stroke to the forward (reverse) direction according to the program. In this way, the gas is first sent to the vertical fire duct without air feeding first, which violates the heating principle and is extremely dangerous.

2. Coke oven gas stroke or chain wheel fracture: once the gas travel or chain wheel breaks down, there are some or all (depending on the specific position of the travel fracture) exchange on site. Cocker did not turn off the gas, but the gas cylinder is still in normal operation. The limit stop connected to the cylinder rod end of the exhaust gas cylinder still touches the mid point limit of the gas travel, and sends the signal to the reversing machine The reversing machine runs the exhaust gas stroke to the forward (reverse) direction according to the procedure. In this way, there will be only gas but no air in some or all vertical fire ducts. If air is sent suddenly, it will cause explosion, damage the furnace body and equipment, and endanger the safety of operators.

summary of the invention

The purpose of the utility model is to provide a kind of anti fracture device for coke oven gas travel, with simple structure, which can sense the chain fracture in time, eliminate the hidden danger of accidents, and is convenient to use.

The purpose of the utility model is to realize in this way that the anti fracture device for coke oven gas travel includes a coke oven gas travel chain and a coke oven waste gas travel chain, and a pull rope is respectively installed on the chain wheel of the coke oven gas travel chain and the chain wheel shaft of the coke oven waste gas travel chain Displacement sensor The pull rope is respectively connected on the chain and the pull rope Displacement sensor They are respectively connected to the regional electrical control system.

The utility model has the advantages of simple structure, simple structure and easy operation Rope displacement sensor It can sense the fracture of the chain in time, eliminate the hidden danger of accident, and is easy to use.

Description of drawings

In the following, a detailed description of the utility model will be given in combination with the attached drawings.

Fig. 1 is a schematic diagram of the connection structure of the utility model. Anti fracture device for coke oven gas travel with rope displacement sensor Specific implementation mode

A coke oven gas travel anti fracture device, as shown in figure I, includes coke oven gas travel chain and coke oven exhaust gas travel chain, which is installed on the sprocket shaft of coke oven gas travel chain Rope displacement sensor 2. It is installed on the sprocket shaft of coke oven waste gas travel chain Rope displacement sensor 1. The pull ropes are respectively connected to the corresponding chains, Rope displacement sensor They are respectively connected to the regional electrical control system. When the chain breaks, Rope displacement sensor It can sense the fracture of the chain in time, eliminate the hidden danger of accident, and is easy to use.
