Background
In the smelting process of the reduction tank, a powdery reducing agent needs to be added into the tank, compressed air is introduced into the reduction tank, and the reducing agent is blown into a process pipeline. When the operation is completed, pressure is arranged in the tank, and the original pressure relief mode is to open a pneumatic gate valve of the feed inlet for pressure relief. Because the pressure in the tank is big, the pressure release is fast when opening pneumatic gate valve, can cause the loss of material and produce a large amount of dust, causes work and the serious pollution of surrounding environment, and the operation environment is abominable, leads to the fact the influence to workman's health even.
Disclosure of Invention
In view of the problems in the prior art, the object of the present invention is to provide a reduction tank emptying pipeline, which can reduce the pressure release speed by using the emptying pipeline, reduce the dust pollution, and provide a good safe working environment.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the reduction tank emptying pipeline is characterized by comprising: the device comprises a tank body and a material hopper arranged at the top of the tank body, wherein a pneumatic gate valve is arranged between the material hopper and the tank body; one side of the top end of the tank body is connected with an air inlet pipe, the bottom end of the tank body is provided with a compressed air pipeline, the bottom end of the tank body is provided with a manual gate valve, and the bottom end of the tank body on the side opposite to the position of the air inlet pipe is connected with a material outlet pipeline.
Further, an exhaust vent pipe is arranged at the top end of the tank body adjacent to the pipe orifice of the air inlet pipe, and a control valve is arranged at the inlet end of the exhaust vent pipe; the gas in the tank body is decompressed through the exhaust vent pipe, so that the decompression speed of the tank body can be reduced, and the dust pollution is reduced;
furthermore, one end of the air inlet pipe is connected to the top of the tank body, the other end of the air inlet pipe is connected to the compressed air pipeline, and the air inlet pipe is provided with a control valve;
further, a control valve is arranged at the inlet end of the compressed air pipeline;
furthermore, a control valve is arranged on the material outlet pipeline.
The utility model discloses a theory of operation is:
blowing a part of gas with specific pressure generated by an air compressor into the tank body through an air inlet pipe, adding a solid powder reducing agent into the tank body through a feed inlet, and generating the gas with specific pressure for blowing; when the operation is finished, pressure is contained in the tank; and opening an exhaust vent pipe control valve at the top of the tank body to slowly release the pressure of the tank body.
The utility model has the advantages that: an exhaust pressure relief pipeline is added on the tank body, so that the pressure relief speed is reduced, the dust pollution is reduced, and the working efficiency of the reduction tank is improved.

The reduction tank evacuation line, as shown in figure 1, comprises: the device comprises a tank body 1 and a material hopper 2 arranged at the top of the tank body 1, wherein a pneumatic gate valve 3 is arranged between the material hopper 2 and the tank body 1; one side of 1 top of the jar body is connected with intake pipe 4, and 1 bottom of the jar body is equipped with compressed air pipeline 5, and 1 bottom of the jar body is equipped with manual gate valve 6, is connected with material outlet pipeline 7 in the jar body 1 bottom of the one side opposite with the intake pipe 4 place.
Further, an exhaust vent pipe 8 is arranged at the top end of the tank body 1 adjacent to the position of the pipe orifice of the air inlet pipe 4, and a control valve 8-1 is arranged at the inlet end of the exhaust vent pipe 8; the gas in the tank body 1 is decompressed through the exhaust vent pipe 8, so that the decompression speed of the tank body 1 can be reduced, and the dust pollution is reduced;
furthermore, one end of the air inlet pipe 4 is connected to the top of the tank body 1, the other end of the air inlet pipe is connected to the compressed air pipeline 5, and the air inlet pipe 4 is provided with a control valve 4-1;
further, a control valve 5-1 is arranged at the inlet end of the compressed air pipeline 5;
furthermore, a control valve 7-1 is arranged on the material outlet pipeline 7.
A part of gas with specific pressure generated by an air compressor is blown into the tank body 1 through an air inlet pipe 4, a solid powder reducing agent is added into the tank body 1 through a charging hole, and the air compressor is used for generating the gas with specific pressure for blowing; when the operation is finished, the tank 1 is pressurized; and opening an exhaust vent pipe control valve 8-1 at the top of the tank body 1 to slowly release the pressure of the tank body 1.
The specific process flow is as follows:
firstly, the pneumatic gate valve 3 is opened, and the powdery reducing agent is directly added into the tank body 1 through the material hopper 2. After the feeding is finished, closing the pneumatic gate valve 3; opening a compressed air control valve 5-1, opening a control valve 4-1, and uniformly stirring the reducing agent in the tank body 1; then the process line valve 7-1 is opened and then the manual gate valve 6 is opened to blow the reducing agent into the process line. And when the reduction process is finished, closing the manual gate valve 6, closing the control valve 4-1, closing the compressed air control valve 5-1, and finally closing the process pipeline control valve 7-1. At this time, the pressure in the tank 1 is still present, and the exhaust line control valve 8-1 is opened to remove the pressure in the tank 1.
