Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection dust removal, and specifically relates to a movable dust collection device for a section steel roughing mill module and a using method thereof. Background Art

[0002] When the roughing mill of the section steel rolling mill is working, it performs pressure rolling on the steel billet. As Figure 4 shown, the unrolled steel billet enters the pressing rolling mill through the first driving roller table 7. After being pressed by the rolling mill, it forms a semi-finished section steel, which is transported to the next production line by the second driving roller table 8. The pressing rolling mill adopts a two-high rolling mill. Since scale is generated on the surface of the steel billet during the heating process, when passing through the rolling mill, the scale is pulverized and thrown around the rolling mill, forming a large amount of dust in the air, causing dust pollution, and the dust will escape along the periphery of the rolling mill housing 6.

[0003] Since the space above the rolling mill housing 6 is open, setting the capture hood of the large dust removal device above will occupy a large amount of space. Since the dust escapes along the periphery of the rolling mill housing 6, the dust removal effect is not ideal, and the capture hood of the large dust removal device will interfere with the repair and maintenance of the rolling mill. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned problems, and provide a movable dust collection device for a section steel roughing mill module and a using method thereof. By setting a relatively closed space in the rolling mill housing to collect the escaping dust, the movable suction hood can be moved to the side of the driving roller table when not in use, without interfering with the repair and maintenance of the rolling mill.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A movable dust collection device for a section steel roughing mill module, including a support main body, a suction hood support, a top flip dust cover, a movable suction hood, and a side flip dust cover. The support main body is arranged around the rolling mill housing. On both sides of the first driving roller table and the second driving roller table above the support main body, two suction hood supports are respectively arranged. On each of the two suction hood supports, a movable suction hood that moves along the suction hood support is arranged. On both sides of the support main body at the same side of the movable suction hood at the top, inwardly flipping top flip dust covers are arranged, and on the other two sides of the top of the support main body, outwardly flipping side flip dust covers are arranged.

[0006] Further, the support main body includes four legs and a square frame above. On both sides of the top of the support main body along the transmission direction of the first driving roller table and the second driving roller table, upper moving tracks are respectively arranged. In the middle of the legs, square frame-shaped suction hood supports are arranged. On the outer sides of the two suction hood supports, lower moving tracks are arranged, and the movable suction hood can move along the upper moving tracks and the lower moving tracks.

[0007] Further, the mobile dust suction hood is a box body open on one side, including a mobile frame and a dust suction hood. The dust suction hood is installed on the mobile frame. The mobile frame is L-shaped, and the upper and lower sides of the mobile frame are respectively matched with the upper moving track and the lower moving track through walking wheels.

[0008] Further, a dust suction port is arranged on one side of the mobile dust suction hood and is connected to the air inlet of the dust removal system.

[0009] Further, two first rotating shafts are arranged on both sides inside the upper part of the main body of the support. Two top turning plates are respectively arranged on the two first rotating shafts. After the top turning plates turn inwards, the space at the top is closed.

[0010] Further, two second rotating shafts are arranged on the other two sides outside the upper part of the main body of the support. Two side turning plates are respectively arranged on the two second rotating shafts. After the side turning plates turn outwards, the space above the two sides is closed. The mobile dust suction hood closes the space on the other two sides, so that the rolling mill housing is basically a closed space except for the bottom surface. Thus, most of the dust generated by pressing the steel billet is collected by the mobile dust suction hood and then conveyed to the dust removal system for centralized dust removal, and a small part of the dust falls to the bottom for centralized treatment.

[0011] A usage method of a mobile dust collection device for a section roughing mill module includes the following steps:

[0012] s1. Install the main body of the support around the rolling mill housing. The dust suction hood support is located above the horizontal line of the production line. Install the mobile dust suction hood, the side turning dust shielding cover and the top turning dust shielding cover at the corresponding positions.

[0013] s2. During operation, the mobile dust suction hood, the top turning plate and the side turning plate form a semi-closed space around the rolling mill housing. The top turning plate turns inwards to block the upper part of the rolling mill housing, and the mobile dust suction hood and the side turning plate block the surrounding of the rolling mill housing.

[0014] s3. When the two-high rolling mill rolls the steel billet, the generated smoke and dust are enclosed by the dust collection device, and most of them are sucked into the dust removal system through the dust suction hood.

[0015] s4. After use, move the two mobile dust suction hoods from the dust suction hood support to the side of the production line through the walking wheels. At this time, the two-high rolling mill can be repaired, cleaned and maintained.

[0016] Further, as described in s1, side plates can be fixedly arranged under the dust suction hood support of the main body of the support to enclose a more airtight space, and the side turning plates can extend to the bottom.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By enclosing the four sides of the rolling mill housing to form a semi-closed space, the dust is collected centrally, reducing the occupied space.

[0019] 2. When not in use, the movable dust suction hood can be moved to the side of the drive roller table, without interfering with the repair and maintenance of the rolling mill. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Such as Figures 1-4

[0030] Embodiment 1

[0031] The present invention provides the following technical solutions: A moving dust collection device for a section roughing mill module, including a support main body 1, a dust suction hood support 2, a top flipping dust shield 4, a moving dust suction hood 3, and a side flipping dust shield 5. The support main body 1 is arranged around the rolling mill housing 6. On both sides of the upper transmission roller table 1 and the transmission roller table 2 above the support main body 1, two dust suction hood supports 2 are respectively arranged. On each of the two dust suction hood supports 2, a moving dust suction hood 3 that moves along the dust suction hood support 2 is arranged. On both sides of the support main body 1 on the same side as the moving dust suction hood 3 at the top, an inward-flipping top flipping dust shield 4 is arranged, and on the other two sides of the top of the support main body 1, an outward-flipping side flipping dust shield 5 is arranged.

[0032] The support main body 1 includes four legs and a square frame above. On both sides of the top of the support main body 1 along the transmission direction of the transmission roller table 1 and the transmission roller table 2, upper moving tracks 11 are respectively arranged. In the middle of the legs, a square frame-shaped dust suction hood support 2 is arranged. On the outer sides of the two dust suction hood supports 2, lower moving tracks 21 are arranged, and the moving dust suction hood 3 can move along the upper moving tracks 11 and the lower moving tracks 21. The moving dust suction hood 3 is an overall box body with one side open, including a moving frame 31 and a dust suction hood 34. The dust suction hood 34 is installed on the moving frame 31. The moving frame 31 is L-shaped, and the upper and lower sides of the moving frame 31 are respectively matched with the upper moving track 11 and the lower moving track 21 through walking wheels 32.

[0033] A dust suction port 33 is arranged on one side of the moving dust suction hood 3 and is connected to the air inlet of the dust removal system.

[0034] On both sides inside the upper top of the bracket main body 1, there are two first rotating shafts 41. On each of the two first rotating shafts 41, there is a top flip plate 42. After the top flip plate 42 flips inward, it closes the space at the top. On the other two sides outside the upper top of the bracket main body 1, there are two second rotating shafts 51. On each of the two second rotating shafts 51, there is a side flip plate 52. After the side flip plate 52 flips outward, it closes the space above the two sides. The movable dust suction hood 3 closes the space of the other two sides, so that except for the bottom surface, the rolling mill housing 6 is basically a closed space. Thus, most of the dust generated by pressing the steel billet is collected by the movable dust suction hood 3 and then conveyed to the dust removal system for centralized dust removal, and a small amount of dust falls to the bottom for centralized treatment.

[0035] Usage method and working principle: As Figure 4 shown, s1. Install the bracket main body 1 around the rolling mill housing 6. The dust suction hood bracket 2 is located above the production line drive roller path 1 and the drive roller path 2. Install the movable dust suction hood 3, the side flip dust shield 5 and the top flip dust shield 4 at the corresponding positions;

[0036] s2. During operation, the movable dust suction hood 3, the top flip plate 42 and the side flip plate 52 form a semi-closed space around the rolling mill housing 6. The top flip plate 42 flips inward to block the upper part of the rolling mill housing 6, and the movable dust suction hood 3 and the side flip plate 52 block the periphery of the rolling mill housing;

[0037] s3. When the two-high rolling mill rolls the steel billet, the generated smoke and dust are enclosed by the dust collection device, and most of them are sucked into the dust removal system through the dust suction port 33 of the dust suction hood 34.

[0038] s4. After use, move the two movable dust suction hoods 3 from the dust suction hood bracket 2 to the side of the production line through the walking wheels 32. At this time, the two-high rolling mill can be repaired, cleaned and maintained.

[0039] Furthermore, as described in s1, a side plate can be fixedly arranged below the dust suction hood bracket 2 of the bracket main body 1 to enclose a more airtight space, and the side flip plate 52 can extend to the bottom.

[0040] The billet is transported to the pressing rolling mill on the first driving roller table 7. After being pressed by the two-high rolling mill, it is transported to the next production line by the second driving roller table 8. Since scale will be generated on the surface of the billet during the heating process, when passing through the rolling mill, the scale is pulverized and thrown around the rolling mill, forming a large amount of dust in the air, causing dust pollution. The dust will escape along the periphery of the rolling mill housing 6. A support body 1 is built around the rolling mill housing 6, and then a top flipping dust cover 4 and a side flipping dust cover 5 are installed. Along the direction of the production line, a first rotating shaft 41 is installed on the inner side of the top of the support body 1 at the inlet side and the outlet side of the two-high rolling mill, and a top flipping plate 42 is installed on the first rotating shaft 41. During use, the top flipping plate 42 is flipped inwards so that the two top mounting plates cover the space above the two-high rolling mill; after the two top flipping plates 42 are flipped, only a small gap remains between the two top flipping plates 42. A second rotating shaft 51 is installed on the outer sides of the other two sides of the top of the support body 1, and a side flipping plate is installed on the second rotating shaft 51. The two side flipping plates 52 are flipped outwards, and the side flipping plates 52 can extend to the bottom. Mobile dust hoods 3 are installed on the dust hood supports 2 on both sides of the inlet and outlet of the two-high rolling mill. The moving frame 31 and the dust hood 34 of the mobile dust hood 3 are assembled. The side of the mobile dust hood 3 close to the working area of the two-high rolling mill is open. The two mobile dust hoods 3 cover the space above both sides of the inlet and outlet of the two-high rolling mill. In order to make the dust collection space more airtight, a fixed side baffle can be set below the support body 1 and the mobile dust hood 3, so that most of the dust enters the dust removal system through the dust suction ports 33 on the sides of the mobile dust hood 3 for treatment.

[0041] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
