Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of environmental protection dust collection in iron and steel enterprises, and particularly provides a combined dust collection device for an iron ladle car. Background Technique
[0002] In the technological process of metal smelting, a large amount of flue gas is generated in many links. Setting an effective dust collection device near the dust generation point is an important measure to reduce the unorganized emission of flue gas and protect the environment. For the situation where an iron ladle car is used to load an iron ladle into the working position, due to the existence of the spout of the iron ladle, there will be a height difference at the mouth of the iron ladle. The elevation on the side of the spout will be higher than the elevation on the side of the flat ladle mouth. This leads to the fact that in order for the iron ladle to pass normally in the working position, the dust collection hood must be designed according to the elevation of the spout of the iron ladle, resulting in too large a gap between the flat ladle mouth and the dust collection hood, causing flue gas to overflow. Therefore, in order to ensure that the iron ladle can pass normally and ensure the dust collection effect and avoid flue gas overflow, a dust collection device is needed.
[0003] At present, most of them adopt a hydraulic or motor-driven lifting dust collection hood, a movable dust collection hood or a rotating dust collection hood. The equipment occupies a large space, and generally the hydraulic or motor is arranged near the heat source of the iron ladle, which affects its service life, increases its failure rate and requires a certain amount of energy consumption. Content of the Utility Model

[0014] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0015] Refer to Figure 1 and Figure 2 The present utility model provides a combined dust collection device for a ladle car, including a support box 7, a sliding rod 6, a connecting rod 8, a rotating rod 10 and a side dust collection hood 11. The support box 7 is fixedly connected to the ladle car 2. The sliding rod 6 slides through the support box 7. The lower part of the sliding rod 6 is connected to a sliding rod driving structure, and the upper part is rotatably connected to one end of the connecting rod 8. The rotating rod 10 includes a short folding section and a long folding section connected at an obtuse angle. The other end of the short folding section is rotatably connected to the upper side of the support box 7, and the other end of the connecting rod 8 is rotatably connected to the short folding section. The other end side of the long folding section is provided with a side dust collection hood 11. The outer shape of the side of the side dust collection hood 11 away from the long folding section matches the side shape of the fixed dust collection hood 3.
[0016] During the working process, the ladle car 2 stays at the ladle dropping position, and the overhead crane operator uses the overhead crane to put the prepared molten iron ladle 1 into the ladle car 2. The ladle car 2 loaded with the molten iron ladle 1 moves along the track, ready to enter the working position to perform related operations. When the ladle car 2 is about to enter the working position, the sliding rod driving structure drives the sliding rod 6 to move upward in the vertical direction in the bracket box 7, and the sliding rod 6 pushes the connecting rod 8 upward. The connecting rod 8 transmits the external force it receives to the short folding section of the rotating rod 10, pushing the rotating rod 10 to rotate along the fixed axis between the bracket box 7, and the long folding section of the rotating rod 10 gradually rotates to a vertical state. When the ladle car 2 enters the working position, the rotating rod 10 just rotates to the vertical position, and the side dust hood 11 is combined with the fixed dust hood 3 to form a complete and enclosed dust hood. Except for the gap reasonably reserved during the design process, there are no other holes, which effectively controls the airflow activity space and prevents smoke from overflowing.
[0017] After completing the relevant operations at this work station, the ladle car 2 loaded with the molten iron ladle 1 can move forward or backward out of the work station according to the normal production operation process. During the moving out process, the sliding rod driving structure drives the sliding rod 6 to move downward in the bracket box 7 along the vertical direction, and the sliding rod 6 pulls the connecting rod 8 downward, and the connecting rod 8 transfers the external force it receives to the rotating rod 10, pulling the rotating rod 10 to rotate along the fixed axis, and the rotating rod 10 gradually moves away from the vertical state. When the ladle car 2 gradually moves away from the work station, the rotating rod 10 rotates to the open state, and a work process ends here.
[0018] In order to limit the upward and downward movement of the sliding rod 6, as an improvement of the technical solution, two pairs of limiting wheels 12 corresponding to the upper and lower positions are rotatably provided inside the bracket box 7, and the distance between the two limiting wheels 12 of each pair of limiting wheels 12 matches the width of the sliding rod 6, and the sliding rod 6 slides through between the two pairs of limiting wheels 12.
[0019] During the up and down movement of the sliding rod 6 , the sliding rod 6 can only move in the vertical direction through the restriction of the two pairs of limiting wheels 12 , and the limiting wheels 12 can reduce the friction force of the up and down movement of the sliding rod 6 .
[0020] As a specific implementation method of the sliding rod driving structure, the sliding rod driving structure includes a driving wheel 5 and a ramp-type track 4, the driving wheel 5 is rotatably connected to the lower end of the sliding rod 6, the ramp-type track 4 is fixed on the ground, and the ramp-type track 4 includes an uphill track and a downhill track on both sides.
[0021] During the closing process, the driving wheel 5 begins to contact the uphill track of the slope track 4. As the ladle car 2 moves forward, the driving wheel 5 moves uphill. The uphill track gives the rotating driving wheel 5 an oblique upward force. Through the restriction of the two pairs of limiting wheels 12, the sliding rod 6 can only move in the vertical direction.
[0022] During the opening process, the driving wheel 5 leaves the highest point of the ramp-shaped track 4 and moves downhill. The downhill track of the ramp-shaped track 4 gives the rotating wheel 5 a downward-slanting force, thereby driving the sliding rod 6 to move downward.
[0023] In order to enable the rotating rod 10 to start rotating under a relatively small driving force, a counterweight connecting rod is connected to the short folded section. A counterweight block 9 is provided at the other end of the counterweight connecting rod. Between the long folded section and the counterweight connecting rod, a strengthening connecting rod is provided. Due to the presence of the counterweight 9, during the rotation process, each component is subjected to a relatively small force, is flexible and lightweight, and is not easily deformed.
[0024] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge scope of those of ordinary skill in the art.
