Description
Technical Field
The invention relates to the technical field of sintering machine sealing, in particular to a self-diagnosis sintering machine end sealing device and a control method thereof.
Background
Sintering machines are large-scale mechanical devices used for sintering ore pellets in the metallurgical industry. The belt sintering machine conveys mineral aggregate through a sintering machine trolley and passes through an air box below the trolley, the air box provides negative air pressure to enable the ignited mineral aggregate on the trolley to seep fire downwards, and the mineral aggregate layer is gradually ignited downwards, so that the purpose of complete sintering is achieved. The sintering process needs the bellows to provide enough negative wind pressure so that the sintering effect is more sufficient and the sintering process is more efficient.
In the actual production process, the negative air pressure provided by the air box can not completely act on mineral aggregate on the trolley, air leakage is often generated due to the fact that the sealing effect of sealing devices between the air box and the trolley is not good enough (mainly comprising side sealing devices positioned on two sides in the width direction of the air box and end sealing devices positioned at the head end and the tail end of the air box, the end sealing devices are the end sealing devices), a large amount of air is gushed from the sealing devices, so that the sintering effect and the yield are reduced, and under the condition of air leakage, in order to meet the requirement that the mineral aggregate layer has enough air pressure to sinter and seep fire, the power of the air box needs to be increased, so that unnecessary cost is caused.
The sealing of the sintering machine belongs to dynamic sealing, so that the sealing of the sintering machine in the moving process is realized. The data show that in the domestic actual sintering process, the air leakage rate of the sintering equipment is 50-70%, wherein the air leakage generated at the sealing part of the head end and the tail end of the contact position of the sintering equipment and the bottom beam of the trolley accounts for the most part. The traditional device applied to sintering machine sealing is provided with spring type box sealing, four-connecting-rod transverse contact sealing, single fulcrum line sealing and the like. Although the sealing device can achieve a certain sealing effect, the sealing device has great defects, and particularly after long-time use, air leakage is gradually serious. The concrete defects are as follows:
1. the automation degree of the sealing process is low, only simple mechanical self-adjustment can be carried out, and whether the sealing effect still meets the requirement or not can not be automatically judged and adjusted in a targeted manner;
2. friction is generated between a friction plate (a sealing plate) of the traditional sealing device and a bottom beam of the trolley, particularly when the trolley collapses (the middle part of the bottom beam is sunken downwards), the friction plate and the friction plate generate violent friction, so that a groove mark is gradually rubbed on the friction plate, and the service life is short;
3. the emergency accident can not be handled, when the trolley and the sealing device are stuck or an accident happens, the alarm can not be sent out quickly, the situation can not be handled in time, and the sintering equipment can be damaged to cause great loss in serious cases.
Therefore, the end sealing device which can adapt to different working conditions and adjust in time and can reduce the friction with the bottom beam of the trolley has great significance.

The blade 2 further includes second and third connection blocks 23 and 24 respectively located at the front and rear ends of the body portion 21.
Furthermore, the extension portion 22 is a sector with the side of the main body portion 21 as a radius and the lower end point of the side as a center, and the angle of the extension portion 22 is greater than or equal to one half of the maximum rotation angle of the blade 2.
Further, the distance between adjacent rows of blades 2 is less than one third of the length of the bottom beam of the trolley 9 (the length in the traveling direction of the trolley 9) to ensure that at least three rows of blades 2 participate in the sealing of the bottom beam of each trolley 9. The purpose is to improve the sealing quality.
Further, still include steel brush 8, steel brush 8 is fixed to be set up on the roof 11 and be located the initiating terminal of platform truck 9 advancing direction, the top of steel brush 8 and the interference fit of platform truck 9 floorbar.
In order to achieve the other purpose, the invention adopts the following technical scheme:
a wind pressure sensor 5 detects a wind pressure value between each row of blades 2 and a bottom beam of a trolley 9 and feeds the wind pressure value back to a controller 7, so that the controller 7 analyzes the wind pressure value and controls the blades 2 of the corresponding row to act through a driving part 4, and a gap between the upper end of each blade 2 and the bottom beam of the trolley 9 is kept within a preset gap range.
Further, the vibration sensor 6 detects a vibration signal and feeds the vibration signal back to the controller 7, and the controller 7 turns off the power supply of the sintering machine and gives a fault alarm when the vibration signal is higher than the upper limit of the preset threshold.
Further, when the wind pressure value detected by the wind pressure sensor 5 on the row of blades 2 is within the preset normal wind pressure range, the controller 7 determines that the gap between the upper end of the row of blades 2 and the bottom beam of the trolley 9 is within the preset gap range, and the controller 7 does not control the driving part 4 to drive the row of blades 2 to rotate.
Further, when the wind pressure value detected by the wind pressure sensor 5 on the row of blades 2 is higher than the preset normal wind pressure range, the controller 7 judges that the gap between the upper end of the row of blades 2 and the bottom beam of the trolley 9 is higher than the preset gap range, and the controller 7 controls the driving part 4 to drive the row of blades 2 to rotate, so that the upper end of the blades 2 is lifted until the wind pressure value detected by the wind pressure sensor 5 on the row of blades 2 falls back to the preset normal wind pressure range.
Further, when the wind pressure value detected by the wind pressure sensor 5 on the row of blades 2 is lower than the preset normal wind pressure range, the controller 7 determines that the gap between the upper end of the row of blades 2 and the bottom beam of the trolley 9 is lower than the preset gap range, and the controller 7 controls the driving part 4 to drive the row of blades 2 to rotate, so that the upper end of the blades 2 descends until the wind pressure value detected by the wind pressure sensor 5 on the row of blades 2 is increased to the preset normal wind pressure range.
In normal sintering process, platform truck 9 gos forward on fixed track, and when a platform truck 9 was close to sealing device gradually, the first contact with steel brush 8 of platform truck 9 floorbar swept away the solid particle that adheres on the platform truck 9 floorbar, avoids leading to the gap increase between blade 2 and the platform truck 9 floorbar because of the effect of solid particle. The trolley 9 continues to move forward and moves above the first row of blades 2, the wind pressure sensor 5 detects the wind pressure value of a small gap between the bottom beam of the trolley 9 and the upper part of the blades 2, and it should be noted that a normal gap (a preset gap range) is left between the upper end of the blades 2 and the bottom beam of the trolley 9, and the small gap is not enough to influence the negative wind pressure and the sintering effect of the bellows. Therefore, the trolley 9 and the blade 2 are not in contact with each other, friction is not generated, the sealing effect can be guaranteed, and the wind pressure value of the corresponding position of each wind pressure sensor 5 is detected in real time in the working process of the sintering machine.
When the wind pressure value detected by the wind pressure sensor 5 installed on one row of the blades 2 is within the preset normal wind pressure range, the gap between the bottom beam of the trolley 9 and the row of the blades 2 is considered to be within the preset gap range, and no contact occurs. In the process, the vibration sensor 6 only detects a normal vibration signal (the vibration signal is lower than the preset upper threshold), the controller 7 does not send an alarm, and the driving part 4 is not controlled to move.
When the bogie 9 collapses due to long-term use in a high-temperature environment, the bottom beam of the bogie 9 bends downward. When the bottom beam of the waist collapse trolley 9 passes through the sealing device, the gap between the waist collapse position of the bottom beam and the blade 2 is reduced or the bottom beam and the blade are in mutual contact, and the wind pressure value detected by the wind pressure sensor 5 at the position is reduced. To avoid the blade 2 from being worn due to excessive friction, the controller 7 controls the driving member 4 to push the connecting rod 3 to rotate and lower the blade 2 at the position by a certain height until the wind pressure sensor 5 detects a wind pressure value within a preset normal wind pressure range, and at this time, the gap between the blade 2 and the bottom beam of the trolley 9 returns to the preset gap range. The process vibration sensor 6 only detects a normal vibration signal and the controller 7 does not send an alarm.
When the trolley 9 moves forward, the gap between the blade 2 and the bottom beam of the trolley 9 is too large, when the trolley 9 walks over the position of the blade 2, the wind pressure sensor 5 detects a wind pressure value exceeding a preset normal wind pressure range, a large wind leakage phenomenon exists between the blade 2 and the bottom beam at the moment, in order to avoid continuous wind leakage, the controller 7 controls the driving part 4 to pull the connecting rod 3 to enable the blade 2 at the position to rotate and rise by a certain height, and the gap between the blade 2 and the bottom beam of the trolley 9 is reduced until the wind pressure sensor 5 detects the wind pressure value within the preset normal wind pressure range. In the process, the bottom beam of the trolley 9 is not contacted with the blade 2, and abrasion is not generated. The vibration sensor 6 only detects a normal vibration signal and the controller 7 does not send an alarm.
When the vibration sensor 6 detects a vibration signal exceeding a set normal range, it is considered that in this case, a transient contact occurs between the bottom beam of the trolley 9 and the blade 2 and strong vibration and friction are generated, and the controller 7 rapidly turns off the power supply to stop the operation and gives a fault alarm to wait for a worker to handle.
Compared with the prior art, the invention has the technical effects that:
the invention adjusts the sealing condition in real time by detecting the air pressure values at different positions, can quickly adjust each air leakage position in time under different working conditions, and has high automation degree and strong pertinence;
in the normal sealing process, a gap is reserved between the upper end of the blade 2 and the bottom beam of the trolley 9, the blade 2 cannot be in close contact with the bottom beam of the trolley 9, abrasion cannot be caused, and the service life is long;
the vibration sensor 6 is arranged, when the trolley 9 and the sealing device are stuck or an accident happens, an alarm can be given out quickly and the machine is stopped, so that the safety is high;
the driving part 4 and the connecting rod 3 are in normal-pressure normal-temperature working areas, are not easy to damage, cannot cause excessive fault problems due to long-time work, and are not easy to damage;
the waist-collapsing phenomenon of the trolleys 9 with different degrees can be adapted, even if the trolleys 9 collapse seriously, the sealing gaps can be corrected rapidly and the sealing quality is ensured even if the trolleys 9 collapse seriously and the plurality of trolleys 9 collapse continuously.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may be modified or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
