Description

Technical Field

[0001] The invention relates to the field of dust removal devices, and in particular to a mobile dust removal device for a ladle turret. Background Art

[0002] Environmental protection requirements are becoming increasingly stringent. Dust-generating points in the workshop should be equipped with dust removal facilities to effectively collect smoke and dust, especially for large bags of continuous casting machines. In the past, roof dust hoods were mostly used for large bags of continuous casting machines. The construction of roof dust hoods does not affect production and does not require daily maintenance and management. However, the roof hoods are installed at a high height, the air volume is set large, the cost is high, the smoke and dust are seriously diffused, and the dust collection effect is poor. They can only partially remove the smoke and dust generated in the large bag area.

[0003] Existing technology: high-position tracks are set up using the factory columns on both sides of the continuous casting ladle, and low-position tracks are set up on the columns of the casting platform. An integral mobile dust hood of the continuous casting ladle is installed on the track. The dust hood moves longitudinally in the workshop. The side panels of the dust hood body are installed at a height higher than the lifting arm of the continuous casting ladle to ensure that the mobile hood can move freely above the ladle.

[0004] Disadvantages of the prior art: To ensure the free movement of the dust hood, the side panels of the dust hood cannot extend downward beyond the lifting arm, the installation height of the dust hood is still relatively high, and the sealing is not complete. During the rising process of the smoke generated by the lower water inlet and the middle bag position, the smoke rises along the outer wall of the large bag after the large bag body is disassembled, and diffuses to the surroundings, causing part of the smoke to be unable to be collected in the dust hood. There is a lack of guide plates inside the dust hood, and the smoke gradually diffuses to the surroundings during the rising process. The dust hood is generally set larger, and the suction interface is relatively small. After being captured by the dust hood, if the smoke cannot be removed in time, it may escape along the outer wall of the smoke hood. Summary of the invention

DETAILED DESCRIPTION

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] like Figures 1 to 5 As shown, an embodiment of the present invention provides a mobile dust removal device for a ladle turret, comprising a track, a first dust cover 1 and a second dust cover 2 of the same structure. The first dust cover 1 and the second dust cover 2 of the same structure can be slidably arranged on the track, the first dust cover 1 and the second dust cover 2 can be symmetrically arranged on both sides of the ladle turret, and the first dust cover 1 and the second dust cover 2 can form a complete dust cover at the ladle turret, a first opening groove is arranged at the rear sealing plate of the first dust cover 1, and a second opening groove is arranged at the rear sealing plate of the second dust cover 2, and the first opening groove and the second opening groove can be connected to form a receiving opening for accommodating the ladle turret mechanical arm 15.

[0025] The first dust hood 1 and the second dust hood 2 are symmetrically arranged and capable of sliding toward each other, so that the first dust hood 1 and the second dust hood 2 can slide symmetrically on both sides of the ladle turret, and the accommodating opening can avoid the interference between the first dust hood 1 and the second dust hood 2 and the robot arm 15, thereby minimizing the overall height of the dust hood, increasing the sealing effect, and improving the dust collection efficiency.

[0026] It should be noted that the continuous casting ladle 14 of the ladle turret is arranged in the middle, and the first dust removal hood 1 and the second dust removal hood 2 are arranged on both sides of the continuous casting ladle 14 respectively.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, the track includes a high-level track 3 and a low-level track 4 arranged in parallel and at intervals, and the first dust hood 1 includes a dust hood body, a high-level track beam and a low-level track beam. The dust hood body includes a rear cover plate, a side cover plate 8 and a top plate. The rear cover plate and the side cover plate 8 are arranged in the vertical direction, and one side of the rear cover plate is vertically connected to one side of the side cover plate 8. The top plate cover is arranged on the top of the rear cover plate and the side cover plate 8, and one end of the top plate away from the rear cover plate is connected to the other side of the side cover plate 8. The high-level track beam and the low-level track beam are arranged in parallel and at intervals at the bottom of the dust hood body. The high-level track beam is connected to the high-level track 3, and the low-level track beam is connected to the low-level track 4.

[0028] In the embodiment, the rear sealing plate and the side sealing plate 8 of the first dust hood 1 are arranged perpendicular to each other to form two side walls of the first dust hood 1, the lower surface of the top wall is connected to the top of the rear sealing plate and the side sealing plate 8, and the top wall is bent downward at one end away from the rear sealing plate and connected to the side sealing plate 8 to form the side wall of the first dust hood 1 at the front end.

[0029] Preferably, if Figure 3 As shown, the side sealing plate 8 is roughly in an inverted L-shaped structure, and the side sealing plate 8 will not pass through the continuous casting ladle 14, so the high-level track 3 can be made lower, and the side sealing plate 8 can extend downward to the top of the continuous casting ladle 14, so as to minimize the overall height of the first dust hood 1 and the second dust hood 2, enhance the sealing performance, and improve the smoke collection rate. A step ladder 9 arranged in a vertical direction is fixedly installed on the outer side of the side sealing plate 8. Through the step ladder 9, you can go up to the top of the dust hood for maintenance and other operations.

[0030] The first dust hood 1 and the second dust hood 2 have the same structure and are symmetrically arranged. When the first dust hood 1 and the second dust hood 2 are in contact, the rear sealing plate of the first dust hood 1 and the rear sealing plate of the second dust hood 2 are connected to each other and form a complete rear sealing plate 12. A rectangular accommodating opening is arranged on the rear sealing plate, and a flexible sealing component is arranged on the inner periphery of the accommodating opening to prevent smoke and dust from overflowing when the mechanical arm 15 is placed in the accommodating opening. The complete rear sealing plate 12 can effectively enclose the continuous casting ladle 14 to prevent smoke and dust from drifting to the outside, and can also greatly reduce the inhalation of cold air.

[0031] It should be noted that the shape of the receiving opening in this embodiment is the same as the cross-sectional shape of the mechanical arm 15 , and when the cross-sectional shape of the mechanical arm 15 changes, the shape of the receiving opening can be changed accordingly. The size of the receiving opening should be slightly larger than the cross-sectional area of ​​the mechanical arm 15 .

[0032] Here, the mechanical arm 15 is the structure of the ladle turntable itself. Ladle covers are hung at both ends of the mechanical arm 15. The ladle covers are covered on the ladle mouth to prevent heat loss and smoke. When the lifting arm is lifted to a certain height, the ladle cover leaves the ladle mouth. At this time, the cast ladle is transferred to another direction, and the ladle with molten steel in the other direction rotates over for further casting, and the cycle repeats.

[0033] In this embodiment, the high-position rail beam and the low-position rail beam both include a driving wheel and a driven wheel. That is, the high-position rail beam and the low-position rail beam form a sliding trolley structure, and the sliding trolley has a driving wheel 5 and a driven wheel. The driving wheel 5 can drive the sliding trolley to slide the first dust cover 1. Correspondingly, the high-position rail beam and the low-position rail beam with the same structure are also provided at the second dust cover 2, and similarly, this structure can also drive the second dust cover 2 to slide.

[0034] In this embodiment, the mobile dust removal device also includes a dust removal duct 16. A first half groove is provided on the top plate of the first dust removal hood 1, and a second half groove with the same structure is provided on the top plate of the second dust removal hood 2. The first half groove and the second half groove can abut against each other and form a suction interface duct 10 for connecting the dust removal duct.

[0035] The dust removal duct 16 is connected to components such as a bag dust collector and is used to transport the smoke to the bag dust collector for processing, and the smoke is processed in the bag dust collector.

[0036] Since the overall installation height of the first dust hood 1 and the second dust hood 2 is lowered and there is enough space between them and the crane beam, the suction interface duct 10 on the top can be installed to improve the dust removal effect.

[0037] The first dust cover 1 and the second dust cover 2 are provided with a deceleration and positioning mechanism, which is used to decelerate and position the first dust cover 1 and the second dust cover 2 when they move toward each other, so as to ensure that the first half groove and the second half groove are smoothly connected. A flexible sealing component is provided at the abutment between the first half groove and the second half groove to prevent smoke and dust from escaping.

[0038] like Figure 2 As shown, in this embodiment, a dust removal valve 11 for controlling opening and closing is provided on the suction interface pipe 10. The dust removal valve 11 can control the opening and closing of the suction interface pipe 10, so that the suction interface pipe 10 is connected to the dust removal pipe 16.

[0039] The first dust hood 1 further includes a guide plate 13, which is a plate-shaped structure, and the two ends of the guide plate 13 are respectively connected to the top plate of the first dust hood 1 and the side sealing plate 8 of the first dust hood 1. The guide plate 13 is arranged obliquely with respect to the horizontal plane, and the upper end of the guide plate 13 is located near the first half groove, and the lower end of the guide plate 13 is fixed on the side sealing plate 8 to form an inclined guide surface. The guide plate 13 is also arranged in the second dust hood 2, and the structure and connection relationship of the guide plate 13 here are the same as those in the first dust hood 1, and will not be described in detail here.

[0040] like Figure 1 and Figure 2 As shown, the mobile dust removal device of the ladle turret also includes a cantilevered tripod 6, which is a frame-like structure, and the high-level track 3 is arranged on the cantilevered tripod 6. The cantilevered tripod 6 is a conventional structure, and its specific shape and connection relationship are not repeated here.

[0041] The mobile dust removal device of the ladle turret further comprises a plurality of low-level support columns 7 arranged at intervals, and the low-level rail 4 is arranged on the top of the plurality of low-level support columns 7. The low-level rail 4 is erected at the top position of the low-level support column 7, and the height of the low-level rail 4 is lower than the height of the high-level rail 3.

[0042] When the embodiment of the present invention is applied, the first dust hood 1 and the second dust hood 2 are respectively located at the waiting positions on both sides of the continuous casting ladle 14. When the continuous casting ladle 14 rotates to the pouring position, the first dust hood 1 and the second dust hood 2 move toward the middle until they are fitted together. At this time, the suction interface pipe 10 is aligned with the interface of the dust removal pipe 16, the dust removal valve 11 is opened, and exhaust dust is carried out while the ladle is being poured. After the pouring is completed, the first dust hood 1 and the second dust hood 2 move to both sides back to the waiting positions, the continuous casting ladle 14 rotates, and the pouring ladle is replaced to complete a working cycle.

[0043] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0044] (1) Reducing pollutant emissions from the plant: This embodiment does not affect the normal production and operation of the casting ladle, and can also effectively collect smoke and dust, thereby improving the workshop environment.

[0045] (2) Improve the smoke capture rate: In the case of a non-enclosed hood, the smoke can be kept in a confined space to the greatest extent possible to prevent it from floating around, while reducing the inhalation of cold air. Sealing is the best choice. In order to reduce the installation height of the dust hood, the two side sealing plates of the dust hood are extended downward, and a double-sided dust hood is used instead of an integral dust hood.

[0046] (3) Improve the working environment of workers: During the pouring process, there is a dust cover to block the heat radiation, reduce the surrounding temperature and improve the working environment.

[0047] (4) Reduce investment: The better the sealing effect, the better the dust removal effect. Reduce the intake of cold air, collect smoke and dust efficiently, relatively reduce the air volume, and reduce investment.

[0048] The above is only a specific embodiment of the present invention, and cannot be used to limit the scope of the invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention, should still fall within the scope of this patent. In addition, the technical features of the present invention can be freely combined with each other, with each other, and with each other.
