[0038] A furnace sampling protection device and a smelting device provided in an embodiment of the present application can reduce or prevent the contents of the furnace from splashing out of the sampling hole.

[0039] In the first aspect of this application, Figure 1 A schematic partial structural diagram of a furnace sampling protection device provided in an embodiment of the present application, referring to Figure 1 , a furnace sampling protection device is provided, including: a sealing device and a driving member.

[0040] In some examples, the sealing assembly can cover at least a portion of the sampling hole of the dust hood. The dust hood includes contents, such as molten iron. The contents can splash to the outside of the dust hood through the sampling hole. The sealing assembly is disposed at the sampling hole to block the contents, thereby reducing or preventing the contents from splashing out of the sampling hole.

[0041] Exemplary, reference Figure 1 The sealing assembly 200 can cover all the sampling holes of the dust cover 100. When the sampling operator needs to perform sampling operations, the sealing assembly 200 can be flipped or rotated to open part of the sampling holes 110 for sampling operations to prevent the contents in the dust cover 100 from splashing out of the sampling holes 110. In addition, the wall surface of the sealing assembly 200 can also play a role in preventing the contents from splashing.

[0042] Exemplarily, the sealing assembly can cover part of the sampling hole of the dust cover, so that the opening of the sampling hole is reduced. The sampling operator can take samples through the opening of the sampling hole, and the sealing assembly prevents the contents in the dust cover from splashing out through the sampling hole.

[0043] Exemplarily, by setting the sealing component to correspond to the size of the sampling hole, the sampling hole can be partially or completely covered by the sealing component.

[0044] It should be noted that the above-mentioned partial coverage or full coverage can be understood as the relative relationship between the sealing component and the sampling hole when the sealing component is attached to the dust cover.

[0045] In some examples, the driving member may be disposed on the dust cover, the driving member is connected to the sealing assembly, and the driving member may drive the sealing assembly to open part of the sampling holes or open all of the sampling holes. Correspondingly, the driving member may also drive the sealing assembly to close part of the sampling holes or close all of the sampling holes.

[0046] Exemplary, reference Figure 1 The driving member 300 may include a fixed end and an actuating end. The fixed end of the driving member 300 may be connected to the dust cover 100, and the actuating end of the driving member 300 may be connected to the sealing assembly 200. The driving member 300 may drive the sealing assembly 200 to move, such as rotate or slide. The movement of the sealing assembly 200 may open part or all of the sampling holes 110, thereby facilitating personnel's related operations on the contents.

[0047] It should be noted that the sampling hole of the closed part by the driving member can also be understood as the sampling hole of the open part.

[0048] In the present application, the sealing component is driven by the driving member to cover all or part of the sampling holes, and the sealing component can prevent the contents from splashing out of the sampling holes, so as to avoid the problem of personnel injury caused by the splashing of the contents, such as molten iron. In addition, the sampling holes can be opened by driving the sealing component by the driving member, that is, the sealing component covers part of the sampling holes or does not cover the sampling holes, so as to facilitate personnel to operate the contents.

[0049] Figure 2 A schematic cross-sectional view of a furnace sampling protection device provided in an embodiment of the present application. In some examples, reference Figure 2 The sealing assembly 200 includes a frame 210 and a cover plate 220. The frame 210 can be fitted with the hole wall of the sampling hole 110, and the cover plate 220 can be connected to the side of the frame 210 away from the sampling hole 110. The cover plate 220 can also drive the frame 210 to move, thereby opening part of the sampling holes 110 or all of the sampling holes 110, and closing part of the sampling holes 110 or all of the sampling holes 110.

[0050] Exemplary, reference Figure 1 The driving member 300 drives the sealing assembly 200 to cover the sampling hole 110, and the frame 210 can be attached to the hole wall of the sampling hole 110 corresponding to the dust cover 100. The cover plate 220 is connected to the frame 210. When the frame 210 is attached to the hole wall of the sampling hole 110 corresponding to the dust cover 100, the cover plate 220 can be used to completely cover the sampling hole 110 to block the contents in the dust cover 100.

[0051] In some examples, the cover may partially cover the frame.

[0052] Exemplarily, the partial covering may be that a portion of the sealing component is attached to the outer wall surface of the dust collection cover corresponding to the sampling hole.

[0053] In some examples, the cover may entirely cover the frame.

[0054] Figure 3 A schematic top view of a furnace sampling protection device provided in an embodiment of the present application. Figure 3 The cross section of the sampling hole 110 may be rectangular, the cover plate 220 may be a cuboid, and the length and width of the cover plate 220 may be equal to the length and width of the hole wall of the sampling hole 110 to achieve full coverage of the sampling hole 110 .

[0055] Exemplarily, the length and width of the cover plate may also be smaller than the length and width of the sampling hole 110 to achieve partial coverage of the sampling hole.

[0056] Exemplary, reference Figure 3The frame 210 has an inner wall and an outer wall. The length and width of the outer wall of the frame 210 may be greater than the length and width of the cover plate 220, and the length and width of the inner wall of the frame 210 may be less than the length and width of the cover plate 220. Part of the structure of the cover plate 220 may be embedded in the inner wall of the frame 210.

[0057] In some examples, partial coverage can be an overlap between the orthographic projection of the sealing component on the plane where the sampling hole is located and the sampling hole. For example, when the driving member drives the sealing component to move, there is a gap between the sealing component and the sampling hole, but part of the sealing component still corresponds to the sampling hole. When the contents in the furnace splash, the sealing component can still block the contents to prevent the splashing of the contents from injuring people.

[0058] In some examples, the sealing assembly further includes a dust curtain, which may correspond to a portion of the sampling hole, and a portion of the dust curtain may be attached to a wall surface of the frame.

[0059] In some examples, dust curtains may correspond to all sampling holes.

[0060] In some examples, the entire dust curtain may be conformable to the wall of the frame.

[0061] Figure 4 A schematic partial structural diagram of another furnace sampling protection device provided in an embodiment of the present application. Figure 4 The dustproof curtain 230 may be connected to the frame 210 , and the dustproof curtain 230 may prevent smoke and dust in the dust cover 100 from escaping through the gap between the sealing assembly 200 and the sampling hole 110 .

[0062] In some examples, reference Figure 3 The dust curtain 230 includes an air jet pipeline 231 , on which a plurality of nozzles are disposed, and the nozzles can spray toward the interior of the dust hood 100 .

[0064] Exemplarily, the nozzle of the air jet pipeline may be directed toward the inside of the dust hood, so that the jetting direction of the nozzle and the splashing direction of the contents in the dust hood may be opposite to each other, so as to prevent the contents from splashing out of the sampling hole.

[0065] In some examples, reference Figure 4 The edge shape of the dust curtain 230 is adapted to the inner wall shape of the frame 210 .

[0066] Exemplarily, the dust curtain can be attached to the inner wall of the frame, and the frame can also be attached to the wall of the sampling hole to prevent smoke in the dust cover from escaping through the gap between the dust curtain and the frame, or the gap between the frame and the wall of the sampling hole.

[0067] In some examples, reference Figure 4 The sealing assembly 200 further includes an asbestos rope 240 , which can be attached to the hole wall of the sampling hole 110 and a part of the wall surface of the dust cover 100 .

[0068] Exemplarily, asbestos rope is a fireproof and heat-insulating material.

[0069] In some examples, the driving member is disposed on one side of the sealing assembly, and the driving member can be connected to the cover plate and the dust cover respectively. The driving member can drive the cover plate along a first direction to partially open or fully open the sampling hole, or partially close or fully close the sampling hole.

[0070] Exemplarily, the frame of the sealing assembly and the cover plate can be set to be slidingly connected, the frame is set at the sampling hole, one end of the driving member can be connected to the cover plate, and the driving member can drive the cover plate to move along a first direction to open or close the sampling hole.

[0071] Exemplary, reference Figure 4 The driving member 300 can drive the sealing assembly 200 to rotate around the rotation axis to drive the sealing assembly 200 to separate from or fit with the sampling hole 110, thereby opening or closing the sampling hole 110. Figure 4 The dotted line in the figure indicates that the driving member 300 drives the cover plate 220 in the sealing assembly 200 to rotate 90 degrees, so that the cover plate 220 can be perpendicular to the plane where the sampling hole 110 is located, and the sampling hole 110 is in an open state, thereby facilitating personnel to operate through the open sampling hole 110.

[0072] Exemplarily, the sealing assembly can be hingedly connected to the dust hood and the driving member respectively, the cover plate can be rectangular, one corner of the cover plate can be hinged to the dust hood, the adjacent corner of the cover plate can be hinged to the actuating end of the cylinder, the rotation direction of the cover plate is perpendicular to the hinge axis, and the rotation direction of the cover plate can be in the plane where the cover plate is located.

[0073] In some examples, reference Figure 3 The driving member 300 includes a cylinder 310 and a base 320. The cylinder 310 can be hingedly connected to a side of the cover plate 220 away from the frame 210, one end of the base 320 can be fixed on the dust cover 100, and the other end of the base 320 can be hingedly connected to the cylinder 310. The cylinder 310 can be extended and retracted along the first direction to drive the sealing assembly 200 to rotate along the hinge axis to open or close the sampling hole 110.

[0074] Exemplary, reference Figure 4 The hinge point of the driving member 300 is arranged on the dust cover 100. During the action of the cylinder 310, the driving member 300 can rotate around the hinge point, for example Figure 4 The dotted line portion in the figure indicates the state after the driving member 300 drives the sealing assembly 200 to rotate, so that the driving member 300 drives the sealing assembly 200 to separate from or fit with the sampling hole 110, thereby realizing the opening or closing of the sampling hole 110.

[0075] In some examples, one end of the cover plate close to the driving member may be hingedly connected to the dust hood.

[0076] Exemplary, reference Figure 4 The hinge shaft is set on the dust collector 100 to drive the cover plate 220 to rotate.

[0077] In some examples, the cylinder may be connected to a pneumatic valve disposed on the sampling platform.

[0078] In some examples, one end of the pneumatic valve is connected to the compressed air, and the other end of the pneumatic valve can be respectively connected to the air inlet and the air outlet of the cylinder.
