Embodiment 1

[0019] figure 2 The blast furnace mud cannon shown in the display device includes a first proximity switch 5 arranged at the operating handle 2 of the rotary gun and a second proximity switch 6 arranged at the operating handle 3 of the mud beating. The first proximity switch 5 The first relay 7 is connected to the corresponding signal input end of the DCS control system 9, the second proximity switch 6 is connected to the corresponding signal input end of the DCS control system through the second relay 8, and the signal output end of the DCS control system 9 is passed through the second relay 8. The three relays 11 are connected to the signal input terminals of the timer 12. The DCS control system has an Ethernet module, and the Ethernet module is connected to the upper computer 10 through a network cable;

[0020] Wherein: when the rotary cannon operating handle 2 is turned to the working position, the predetermined distance between the rotary cannon operating handle 2 and t...

Embodiment 2

[0022] When the electric signal output by the first proximity switch 5 lasts for 35 seconds after induction, it is judged to be the signal of the rotating gun, and the rest are the same as in the first embodiment.

Embodiment 3

[0024] When the electric signal output by the first proximity switch 5 lasts for 50 seconds after sensing, it is judged to be the signal of the rotating gun, and the rest are the same as in the first embodiment.

Abstract

The invention discloses a display device for a mud charging quantity of a blast furnace mud gun and belongs to the technical field of metallurgical equipment. The display device comprises a first proximity switch disposed at a gun turning operation handle and a second proximity switch disposed at a mud charging operation handle; both the switches are connected to a signal input end of a DCS (distributed control system); a signal output end of the DCS is connected with a signal input end of a timer; the DCS is connected with an upper computer through an Ethernet module, wherein the first proximity switch outputs a gun turning signal to the DCS, the DCS judges the gun turning signal and performs data collecting and timing on a mud charging signal output by the second proximity switch until the mud charging signal disappears, the DCS then calculates the collected data and sends them to the upper computer, and the upper computer displays mud charging quantity information. By using the display device, the problem that mud charging quantity of an existing blast furnace mud gun is unable to be accurately metered is solved.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a display device for the amount of mud knocked out by a blast furnace mud cannon. Background technique [0002] Mud cannon is the necessary furnace equipment for smelting that can quickly and accurately block the taphole after the iron is placed. figure 1 The shown blast furnace mud gun includes a gun body 4 and a hydraulic station 1, and an operating valve is arranged on the hydraulic station. [0003] The operating valve includes a rotary cannon operating valve and a mud beating operation valve. The rotary cannon operating valve is provided with a rotary cannon operating handle 2, and the mud beating operation valve is provided with a mud beating operating handle 3; The mud cannon rotates to aim at the blast furnace taphole, and then controls the mud cannon to fire mud through the mud-beating operation handle; among them, the amount of mud pumped by the blast f...
