Background
When the blast furnace is used for normal production, the on-site pressure has important guiding significance for process control, even some pressure has a control effect on equipment, and especially the gas pressure plays a key role in the blast furnace production. However, because of the water content in the main gas pipe and the high dust content, the pressure guide pipe is often blocked, so that the gas pressure is often failed to influence the process control and monitoring of the blast furnace. In order to prevent the gas pressure from malfunctioning, the project is cleared and blocked by the gas pressure discharged for each fix repair, and the labor intensity of personnel is increased. When production fails, the air respirator must be worn for blocking removal, so that the risk of poisoning of operators is greatly increased.

The inlet end of the pressure guide pipe is provided with a first ball valve, and the pressure guide branch pipe is provided with a second ball valve.
The dredging unit comprises a cylinder, an extension rod in the cylinder is used as a dredging rod, and the cylinder drives the dredging rod to extend or retract.
The length of the dredging rod is larger than the length of the impulse pipe and smaller than the sum of the lengths of the connecting pipeline and the total impulse pipe.
The electromagnetic valve is arranged at the joint of the connecting pipeline and the pressure guiding pipe and is in signal connection with the air cylinder.
Compared with the prior art, the utility model has the advantages that: the automatic blockage clearing device for the gas pressure guide pipe does not need to detach the pressure transmitter on site for blockage clearing by personnel, can dredge the pressure guide pipe remotely at any time, ensures the accuracy of gas pressure, reduces the labor intensity of operators, and avoids gas poisoning of the operators during operation.
Drawings
FIG. 1 is a schematic diagram of an automatic blockage removing device for a gas pressure guiding pipe according to an embodiment of the utility model;
in the figure, a gas pipeline 1, a first ball valve 2, a pressure guiding pipe 3, an electromagnetic valve 4, a connecting pipeline 5, a flange 6, a dredging rod 7, an air cylinder 8, a pressure transmitter 9, a pressure guiding branch pipe 10 and a second ball valve 11 are arranged.
Detailed Description
The utility model is described in further detail below with reference to the embodiments of the drawings.
As shown in fig. 1, an automatic blockage removing device for a gas pressure guiding pipe in the embodiment comprises a pressure guiding pipe 3, wherein one end of the pressure guiding pipe 3 is communicated with a gas pipeline 1, and the other end of the pressure guiding pipe 3 is communicated with a connecting pipeline 5. The end part of the connecting pipeline 5 is connected with the dredging unit through a flange 6. The dredging unit sequentially penetrates through the connecting pipeline 5 and the impulse pipe 3, and then the whole impulse pipe 3 is dredged. The side of the pressure guiding pipe 3 is connected with a pressure guiding branch pipe 10, the pressure guiding branch pipe 10 is provided with a pressure transmitter 9 and a second ball valve 11, and in a normal state, the second ball valve 11 is in a normally open state, so that the pressure transmitter 9 monitors the pressure of gas in the pressure guiding pipe.
The dredging unit comprises a cylinder 8, and an extension rod of the cylinder 8 is used as a dredging rod 7. The dredging rod 7 is made of copper material. The length of the dredging rod 7 is greater than the length of the impulse pipe 3, but the length of the dredging rod cannot exceed the sum of the lengths of the connecting pipeline 5 and the impulse pipe 3, so that the dredging rod can penetrate into the impulse pipe when the cylinder acts, and the whole impulse pipe can be safely dredged. The connection part of the connecting pipeline 5 and the guide pipe 3 is provided with an electromagnetic valve 4, and the electromagnetic valve 4 is in signal connection with a cylinder 8. Under normal conditions, the electromagnetic valve is powered off, and the cut-off state between the connecting pipeline and the impulse pipe ensures the accuracy of the pressure value taken by the pressure transmitter.
