Description
Technical Field
The application belongs to the technical field of blast furnace infrared imaging, and particularly relates to a blast furnace imaging equipment withdrawal protection device with a rotation function.
Background
In the blast furnace production process, in order to monitor the working condition and the production condition in the furnace in real time, an industrial monitoring system is required to be installed for the blast furnace, and the condition in the furnace is continuously monitored in real time by generally adopting an infrared imaging lens installed on the furnace top.
The blast furnace imaging equipment is directly arranged on the top of the blast furnace through the preformed hole, the production condition in the furnace is continuously monitored in real time, the movement condition of a swinging chute in the furnace and the distribution condition of a material surface can be observed in real time on a monitor of a control room, and the conditions of material sitting, material collapsing and the like of internal furnace burden are observed in real time, so that the method has guiding significance for controlling the furnace condition of the blast furnace, saving energy and improving the quality of molten iron.
The inside of the blast furnace is high-temperature, high-dust and high-humidity environment, and meanwhile, the pressure of about 0.2MPa and strong updraft exist in the furnace, so that the lens is easy to be polluted. Under the condition of continuous production, the clear and stable image of the system can be ensured only by keeping the lens clean and free from dust accumulation, and the aim of monitoring the working condition in the furnace in real time is fulfilled. Therefore, the method is particularly important for protecting imaging equipment and protecting abnormal conditions (overtemperature, gas and water stoppage and the like) and on-line maintenance in the continuous production process of the blast furnace.
The prior high-temperature imaging protection device and protection system have the following two forms:
1. the structure is that the protecting sleeve of the imaging equipment is inserted into the blast furnace through the ball valve for monitoring. The structure does not automatically exit the protection device, a maintenance person is required to pull out the protection sleeve manually for maintenance, when the system is abnormal or overtemperature alarm occurs, the maintenance person often cannot reach the site to pull out the camera protection sleeve in time, so that a camera or other monitoring equipment and a lens are easy to burn under the condition. In addition, when on-line maintenance is needed, because the pressure in the blast furnace is positive pressure (about 0.2 MPa), in the process that a maintainer pulls out the protective sleeve to close the ball valve, the pressure in the furnace is overcome, and meanwhile, the blast furnace gas is prevented from leaking, so that the potential safety hazard exists.
2. The gate valve type structure is that a pneumatic gate valve is arranged at the front end of a protecting sleeve of the imaging equipment, and when an abnormal condition or overtemperature alarm occurs to the system, the gate valve is automatically closed to protect a camera (or other monitoring equipment) from being damaged. However, this construction has certain limitations in that the entire shielding device is installed outside the blast furnace wall, and the camera probe is not inserted into the furnace, so that the view is small and the opening of the furnace wall is large. The structure is not automatically withdrawn from the protection system, and although the pneumatic gate valve is arranged in front of the camera protection sleeve, when the system is abnormal or overtemperature alarmed, the gate valve can automatically close and protect the camera and the lens, but the sealing effect of the gate valve is far less good than that of a ball valve, and the potential safety hazard problem of the prior plug-in type also exists when on-line maintenance is required.
In order to solve the above-mentioned problems, chinese patent application No. 201410557357.X discloses a "exit guard for a blast furnace imaging apparatus" filed by the present inventors, and fig. 1 is a schematic structural view of the exit guard for a blast furnace imaging apparatus. As shown in fig. 1, the exit protecting device of the blast furnace imaging equipment comprises a shell 1, a furnace door 2, a ball valve 3 and a cylinder 4 which are connected, wherein:
the cylinder 4 comprises a cylinder body 41, a piston 42 and a piston rod 43, wherein the piston rod 43 is of a hollow structure and is provided with an opening at the left end, the right end of the piston rod 43 is connected to the piston 42, a connecting rod 44 is arranged in the piston rod 43, one end of the connecting rod 44 is connected to the right end of the piston rod 43, the other end of the connecting rod is used for installing infrared imaging equipment 5, a cooling gas inlet 411 is arranged on the cylinder body 41, an air hole 421 is arranged on the piston 42, and a position, corresponding to the air hole 421, of the piston rod 43 is provided with an opening to enable the air hole 421 to be communicated with the space in the piston rod 43;
the shell 1, the furnace door 2, the ball valve 3 and the air cylinder 4 are sequentially arranged from left to right and are sequentially and fixedly connected, the left end of the shell 1 is provided with an opening, the piston rod 43 can be contracted to the right side of the ball valve 3 when being completely retracted, the piston rod 43 stretches into the shell 1 when being completely extended, so that the infrared imaging equipment 5 is positioned at the leftmost working position of the shell 1, and the air hole 421 is aligned with the cooling air inlet 411.
However, in practical use, the following problems are found in the exit protection device of the blast furnace imaging equipment:
1. the furnace door 2 and the ball valve 3 are arranged outside the furnace wall side by side, and the furnace door 2 and the ball valve 3 are arranged at the same time, so that the overall length of the device is increased, and the device occupies too much space, is not applicable under the condition that the external operation space of the blast furnace is limited, and can increase the difficulty of maintenance operation.
2. The intake line and the cooling line of the cylinder 4 lack detection means, so that the automation program is low.
3. The infrared imaging device 5 is fixedly installed on the connecting rod 44, so that only the working condition and the production condition of a partial area in the blast furnace, particularly the movement condition of the swinging chute and the distribution condition of the material level can not be simultaneously considered, if the whole blast furnace is to be observed, at least two blast furnace imaging devices with different imaging angles are required to be oppositely installed to exit the protection device, obviously, the production cost can be greatly increased, and the operation cannot be carried out due to the overlarge required operation space.
4. The middle cooling air inlet 21 is provided on the oven door 2, and the middle cooling air from the cooling air pipe passes through the oven door 2 and enters the interior of the piston rod 43, thereby cooling the oven door 2 and the infrared imaging device 5, but the cooling air does not pass through the ball valve 3, and thus the ball valve 3 cannot be cooled effectively.
