Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0025] like Figure 1 , Figure 2 As shown, Figure 1 This is a schematic diagram of the dust collection system provided in an embodiment of this application. Figure 2 This is a top view of the dust collection system provided in an embodiment of this application.

[0026] A dust collection system for a steelmaking continuous casting tundish, the dust collection system comprising a main frame 100 and a working hood 102, wherein:

[0027] like Figure 1 , Figure 2 As shown, the main frame 100 is erected in the working area, and the main frame 100 is provided with a plurality of partition plates 101. The partition plates 101 enclose a first area with a top opening in the working area. The main frame 100 is fixed in the working area of ​​the steelmaking continuous casting tundish, and the main frame 100 is used as the basis for relative arrangement to arrange and coordinate the operation of the working cover 102 and related components.

[0028] like Figure 1 , Figure 2 As shown, multiple partition plates 101 are fixedly installed on the main frame 100 to complete the relative spatial division in the work area. The partition plates 101 form a horizontal barrier against work dust, and the top of the multiple partition plates 101 forms an opening to facilitate production operations.

[0029] like Figure 1 , Figure 2 As shown, the working cover 102 has a collection space inside, and the top of the working cover 102 has a connection port for connecting to the air inlet of the dust removal equipment. The working cover 102 is movably mounted on the main frame 100. When the working cover 102 moves on the main frame 100 to the first area, the working cover 102 and the partition plate 101 enclose the collection space, and the connection port is connected to the air inlet of the dust removal equipment.

[0030] like Figure 1 , Figure 2As shown, the working hood 102 is movably arranged on the main frame 100 and can be moved to different positions to correspond to different production operations. When it is necessary to collect and filter the captured dust, the working hood 102 moves to the top of the first area and forms a collection space with the partition plate 101. The relatively sealed space can achieve better efficiency when the dust removal equipment is pumping air. After the dust removal operation is completed, the working hood 102 can continue to move on the main frame 100 to the target position to complete the separation operation from the first area.

[0031] In an optional embodiment, the working principle of the dust collection system of this application is as follows: The integrated system operates in the tundish working area of ​​steelmaking continuous casting. The dust collection system includes a main frame 100 and a working hood 102. The main frame 100 is erected in the working area, and multiple partition plates 101 are provided on the main frame 100. The partition plates 101 enclose a first area with a top opening in the working area. The working hood 102 has a collection space inside, and the top of the working hood 102 has a connection port for connecting to the air inlet of the dust removal equipment. The working hood 102 is movably mounted on the main frame 100. When the working hood 102 moves on the main frame 100 to the first area, the working hood 102 and the partition plates 101 enclose the collection space, and at the same time, the connection port connects to the dust removal equipment. The air inlet is connected to the working area of ​​the steelmaking continuous casting tundish. Through the movement of the working hood 102, a relatively closed collection space is formed with the partition plate 101 erected in the first area. The dust generated during the operation is collected in the collection space and is sucked out of the working hood 102 and filtered under the operation of the dust removal equipment, which improves the filtration effect of the dust and greatly avoids the disorderly drift of dust. When relevant operations are required, the working hood 102 is moved on the main frame 100 to provide a working space above the first area, thereby improving the reliability of the operation. The large amount of dust generated in steelmaking production is stably restrained by the working hood 102, protecting the overall environment of the workshop, reducing fugitive dust emissions, and achieving the target emission level.

[0032] like Figure 1 , Figure 2 As shown, in an optional embodiment, there are two work covers 102, which are respectively arranged on the main frame 100 and move synchronously in opposite directions. The partition plate 101 encloses two work areas on the main frame 100 that correspond to the two work covers 102 respectively.

[0033] The two working hoods 102 can independently collect smoke and dust in two relatively independent spaces. The two working hoods 102 can move towards or away from each other on the main frame 100 to improve working efficiency. They are also equipped with a dust removal device for dust removal and filtration to improve efficiency.

[0034] likeFigure 1 , Figure 3 As shown, Figure 3 A partial structural diagram of the drive wheel 202 is provided for an embodiment of this application. In an optional embodiment, the main frame 100 is provided with a guide rail 201, and the working cover 102 is provided with a drive wheel 202. The drive wheel 202 is rotatably disposed on the guide rail 201 and reciprocates along the extension direction of the guide rail 201.

[0035] The relative movement of the work cover 102 on the main frame 100 is achieved by the reciprocating movement of the drive wheel 202 on the guide rail 201. The guide rail 201 provides guidance and constraint for the movement of the work cover 102, thereby improving the stability of the operation. It should be noted that in actual configuration, the drive wheel 202 can be rotated forward and backward by arranging a drive motor.

[0036] like Figure 1 , Figure 3 As shown, in an optional embodiment, the inner side of the work cover 102 is provided with a first mounting strip 301, the inner side of the main frame 100 is provided with a second mounting strip 302, and a sealing part 304 is fixedly provided on the first mounting strip 301, the sealing part 304 extending to the second mounting strip 302.

[0037] As the drive wheel 202 reciprocates on the guide rail 201, the first mounting strip 301 is displaced relative to the second mounting strip 302, and the sealing part 304 fixed on the first mounting strip 301 also moves synchronously with the working cover 102. The sealing part 304 is positioned between the first mounting strip 301 and the second mounting strip 302, and forms a barrier between the working cover 102 and the guide rail 201, thereby improving the sealing of the collection space and further preventing the spread of smoke and dust.

[0038] like Figure 1 , Figure 3 As shown, in an optional embodiment, the second mounting strip 302 has a U-shaped groove 303 on the side facing the first mounting strip 301, and the sealing part 304 is a flexible baffle, which extends into the U-shaped groove 303.

[0039] In actual arrangement, one edge of the sealing part 304 extends into the U-shaped groove 303 on the second mounting strip 302 to improve the sealing effect of the sealing strip. At the same time, during the dynamic movement of the sealing strip, the sealing strip always extends into the U-shaped groove 303 to determine a reliable relative position with the second mounting strip 302.

[0040] The sealing part 304 is made of flexible rubber strip.

[0041] In an optional embodiment, a spraying system is provided in the collection space to carry out spraying operations in the collection space, thereby further improving the efficiency of dust settling.

[0042] like Figure 1 , Figure 2 As shown, in an optional embodiment, a connecting pipe 401 is fixedly provided on the working cover 102, and multiple connecting ports are provided. One end of the connecting pipe 401 is connected to multiple connecting ports simultaneously, and the other end of the connecting pipe 401 is used to connect to the air inlet of the dust removal equipment. A control valve 402 is provided inside the connecting pipe 401.

[0043] The connecting pipe 401 on the working hood 102 collects smoke and dust. When the working hood 102 moves to the target position, one end of the connecting pipe 401 is connected to the air inlet of the dust removal equipment to facilitate dust removal operations. The control valve 402 arranged in the connecting pipe 401 can control the flow rate and connection status of the smoke and dust in the connecting pipe 401, making it easier to control the operation under different work procedures.

[0044] like Figure 1 , Figure 2 As shown, in an optional embodiment, the main frame 100 is provided with a trigger part 403 connected to the control valve 402. The working cover 102 can contact the trigger part 403 during movement and switch the working state of the control valve 402 through the trigger part 403.

[0045] By setting a trigger 403 at a preset position and controlling the linkage through the displacement of the working cover 102, when the working cover 102 moves to the first space, it will contact the trigger 403 and cause the trigger 403 to drive the control valve 402 to open, which facilitates the dust removal equipment to start dust removal operation, reduces the difficulty of manual operation and control, and improves the degree of automation.

[0046] In an optional embodiment, the dust collection system further includes a control component, which is connected to the trigger 403, the control valve 402, and the dust removal equipment. When the working hood 102 contacts the trigger 403, the control component can simultaneously control the control valve 402 and the dust removal equipment. The control component integrates the control and dust removal equipment control. When the working hood 102 moves to the working position, the trigger 403 outputs a signal to the control component. Under the control of the control component, the control valve 402 opens, and the dust removal equipment also begins dust removal and filtration operations, improving work efficiency and reducing the difficulty of manual intervention.

[0047] like Figure 1 , Figure 2As shown, in an optional embodiment, the partition plate 101 is provided with an openable and closable operating door 404. In the corresponding operation, the operating door 404 is opened and closed for entry and exit operations. In actual operation, the operating door 404 can be an automatic revolving door or a sliding door to improve the relative sealing effect of the capture space.
