AI Technical Summary
During the existing hot repair of steel ladles, the limited area of the dust collection port of the dust removal system results in low negative pressure, which leads to the intake of a large amount of wild air and unsatisfactory dust removal effect.
The top-suction dust removal device, which adopts a fully enclosed design, forms a closed area through smoke baffles, tracks, and dust collection hoods. The dust removal system creates negative pressure in the limited space, and the smoke collection hood directly adsorbs the smoke and dust.
It improves dust removal efficiency and effectiveness, prevents smoke and dust from overflowing, ensures that smoke and dust are smoothly drawn into the dust removal system, and achieves efficient smoke and dust capture.

Abstract
Description
Technical Field
[0001] This application relates to the field of ladle hot repair technology, and more specifically, to a top-suction dust removal device for ladle hot repair. Background Technology
[0002] Hot repair of the ladle is an important part of the steelmaking process, involving the replacement, maintenance, and cleaning of the ladle sliding nozzle and bottom-blown permeable bricks. The hot repair process generates a large amount of high-temperature dust, which must be treated by a dust removal system before being released into the atmosphere.
[0003] Currently, most dust hoods used for hot repair of steel ladles in domestic steel smelting enterprises are either side-suction or top-suction types, both of which are semi-enclosed. When hot repairing steel ladles, the negative pressure generated is small due to the limited area of the dust suction port, and a large amount of draft air is drawn in, resulting in unsatisfactory smoke and dust removal effect. Utility Model Content
[0004] The purpose of this application is to provide a top-suction dust removal device for hot repair of steel ladles. It adopts a fully enclosed design, which can easily form negative pressure in a limited space, prevent smoke and dust from overflowing, and improve dust removal efficiency and effect.
[0005] This application provides a top-suction dust removal device for hot repair of steel ladles, adopting the following technical solution:
[0006] A top-suction dust removal device for hot repair of steel ladles includes smoke baffles arranged opposite each other on both sides of a hot repair turning platform for steel ladles, tracks arranged opposite each other on both sides of the hot repair turning platform for steel ladles, and a dust collection hood cart arranged on the tracks. The smoke baffles are perpendicular to the tracks. Inspection doors are provided on both sides of the dust collection hood cart. Two smoke collection hoods are provided on the dust collection hood cart, and smoke guide pipes are provided on the smoke collection hoods. The smoke guide pipes are connected to the dust removal system.
[0007] Preferably, the dust collection hood is provided with a sand filling hole.
[0008] Preferably, the smoke barrier wall is provided with a first step ladder.
[0009] Preferably, the dust collection hood is equipped with guardrails and a second step.
[0010] Preferably, the dust collection hood is provided with an observation hole.
[0011] Preferably, a proximity switch is provided on the side of the track.
[0012] Preferably, a limit switch is provided on the side of the track.
[0013] Compared with the prior art, the beneficial effects of this application are as follows:
[0014] This application features convenient operation, strong practicality, and good dust collection effect. During hot repair of the ladle, the dust collection hood is moved above the ladle, and a closed area is formed between the dust collection hood and the smoke baffles on both sides. Under the action of the dust removal system, negative pressure can be easily formed in the limited space to prevent dust from overflowing and improve dust removal efficiency and effect.
[0015] By setting up two inspection doors and two fume hoods, one inspection door can be opened to maintain the ladle sliding nozzle, while the other inspection door can be opened to clean the steel and slag adhering to the ladle opening. Under the action of the dust removal system, a negative pressure is generated inside the fume hoods. One fume hood captures the smoke and dust generated at the ladle sliding nozzle, while the other fume hood captures the smoke and dust generated at the ladle opening, thus ensuring that the smoke and dust are smoothly drawn into the dust removal system. Because it directly adsorbs the smoke and dust, the dust removal efficiency is higher and the dust removal effect is better. Attached Figure Description

[0028] Example
[0029] like Figure 1-3As shown in the embodiment of this application, the top-suction dust removal device for hot repair of steel ladles includes smoke baffles 1 arranged opposite to each other on both sides of the hot repair turning platform of steel ladles, tracks 2 arranged opposite to each other on both sides of the hot repair turning platform of steel ladles, and dust collection hood 3 arranged on the tracks 2. The smoke baffles 1 and the tracks 2 are perpendicular to each other. Inspection doors 4 are respectively provided on both sides of the dust collection hood 3. Two smoke collection hoods 5 are provided on the dust collection hood 3. Smoke guide pipes 6 are provided on the smoke collection hoods 5 and connected to the dust removal system.
[0030] During hot repair of the ladle, the ladle is first placed on the hot repair tilting platform. Under the action of the drive mechanism, the dust collection hood 3 is moved above the ladle, forming a closed area between the dust collection hood 3 and the smoke baffles 1 on both sides. Under the action of the dust removal system, negative pressure can be easily formed in the limited space to prevent smoke and dust from overflowing, thereby improving dust removal efficiency and effect. Opening one side of the inspection door 4 allows for the maintenance of the ladle sliding nozzle, while opening the other side of the inspection door 4 allows for the cleaning of steel and slag adhering to the ladle opening. Under the action of the dust removal system, negative pressure is generated inside the smoke collection hood 5. One smoke collection hood 5 captures the smoke and dust generated at the ladle sliding nozzle, and the other smoke collection hood 5 captures the smoke and dust generated at the ladle opening, thus ensuring that the smoke and dust are smoothly drawn into the dust removal system. Because the smoke and dust are directly adsorbed, the dust removal efficiency is higher and the dust removal effect is better. After the hot repair of the ladle is completed, the dust collection hood 3 is moved to a non-working position, and the ladle is lifted away, thus completing the entire hot repair operation cycle.
[0031] In this embodiment, the dust collection hood 3 is provided with a sand filling hole 7. The sand filling hole 7 facilitates the filling of the ladle sliding gate with diversion sand using a sand filling device.
[0032] In this embodiment, a first step ladder 8 is provided on the smoke barrier wall 1. Workers can climb the first step ladder 8 to reach the top of the dust collection hood vehicle 3, which facilitates manual control of the filling of diversion sand.
[0033] In this embodiment, the dust collection hood 3 is equipped with a guardrail 9 and a second step ladder 10. After the dust collection hood 3 is moved above the ladle, the first step ladder 8 and the second step ladder 10 are merged and aligned. The guardrail 9 plays a protective role and ensures the personal safety of the staff.
[0034] In this embodiment, the dust collection hood 3 is provided with an observation hole 11, which makes it easy for staff to observe the maintenance status of the ladle sliding gate.
[0035] In this embodiment, a proximity switch is provided on the side of the track 2. The proximity switch facilitates the control of the movement position of the dust collection hood 3.
[0036] In this embodiment, a limit switch is provided on the side of the track 2. When the dust collection hood 3 moves to the non-working position, it stops after touching the limit switch.
[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
