Description
Technical Field
The utility model relates to a smelt blast furnace technical field, concretely relates to chain control device of blast furnace roof pressure.
Background
The blast furnace top pressure is the most effective measure for improving the utilization rate of gas, but if an emergency accident or an air supply system failure occurs, the blast furnace top pressure can be suddenly increased, so that the safety of a gas pipeline is threatened, the pressure bearing of the blast furnace top pipeline and equipment is threatened, and production equipment is damaged.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose causes the outer transport of coal gas to be obstructed because of equipment proruption trouble or gas system trouble in solving blast furnace production, and it risees to send the blast furnace roof pressure to cause the influence to blast furnace production.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides an interlocking control device of blast furnace roof pressure, includes fixed blast furnace body (1) bottom on furnace base (2), and blast furnace body (1) top sets up furnace throat (3), installs material loading bucket (4) on furnace throat (3), sets up respectively in the both sides at furnace throat (3) and blast furnace body (1) top and diffuses pipeline (5) and high-pressure tube (6), installs the motorised valve respectively on diffusing pipeline (5) and high-pressure tube (6), and the motorised valve electricity is host computer even.
The utility model discloses technical scheme's further improvement lies in: the diffusing pipeline (5) is vertically arranged at the furnace throat (3) and is higher than the feeding tank (4).
The utility model discloses technical scheme's further improvement lies in: the high-pressure pipe (6) is vertically arranged on one side of the top of the blast furnace body (1) and has the diameter of 20-30 cm.
Compared with the prior art, the utility model provides a pair of interlocking control device of blast furnace roof pressure has beneficial effect as follows:
1. the utility model provides an interlocking control device of blast furnace roof pressure, the device set for through the host computer and diffuse the motorised valve control value on pipeline and the high-pressure tube, when setting up the 20Kpa that the threshold value surpassed the setting value, and the motorised valve on pipeline and the high-pressure tube of diffusing opens and carries out the pressure release, and after pressure was less than the threshold value setting value, motorised valve self-closing ensured the normal operation production of blast furnace condition and each pipeline.
