Description
Technical Field
[0001] This application relates to the technical field of dust collection for heavy plate rolling mills, and more specifically, to a dust suction device for heavy plate rolling mills. Background Art
[0002] The heavy plate production line in a general steel plant mainly includes equipment such as roughing mills, finishing mills, thickness measuring instruments, flame cutting machines, and on-line flaw detectors. The main dust generation points on the production line are at the outlet of the rolling mill, and the dust is caused by factors such as rolling crushing, high-temperature quenching crushing, high-temperature vaporization of cooling water, and high-speed movement of rolled materials causing air flow. The original design of the rolling mill used cooling water mist suppression. However, the dust capture ability of water mist suppression for large particle oxidized dust is insufficient, and there is a large amount of smoke and dust overflowing and floating in the air. During the production process of the finishing mill, there are a large number of phenomena of emitting yellow smoke and yellow dust. Especially when producing thin specifications and variety steel controlled rolling in the second stage, the yellow smoke around the entire rolling mill is particularly serious, resulting in a poor on-site working environment.
[0003] The main functions of the guide device of the rolling mill include correctly guiding the rolled piece into the roll pass, ensuring that the rolled piece deforms stably in the pass, and obtaining the required geometric shape and dimensions; smoothly guiding the rolled piece out of the pass to prevent coiling of the rolls. The guide device is usually divided into a guide frame body and a lifting hydraulic cylinder. There are two lifting hydraulic cylinders on one guide frame body, and the head of the lifting hydraulic cylinder rod is hinged to the guide frame body through a pin shaft. The guide frame body is a welded structural member, with a 150 mm steel plate at the lower end. The front end of the steel plate is processed with a stepped groove and has a certain inclination angle with the rolling line. Holes and grooves are processed at the corresponding positions of the steel plate, and nozzles spray dust removal and descaling water through the holes and grooves.
[0004] In the existing dust removal process route, the guide device has a single function, has no linkage with other functional components of the heavy plate rolling mill, and occupies a large space, resulting in insufficient installation space for traditional dust suction devices and poor dust suction effect. Or it is captured by a large hood set outside the rolling mill, and equipment such as pipe networks, dust removal ground stations, and fans are used to conduct air extraction and dust removal for the guide device. However, the large hood requires a large air volume, has a high construction cost, high operating energy consumption, and relatively high operating costs. How to reduce dust removal costs and energy consumption is a consideration for those skilled in the art. Summary of the Utility Model
[0005] This application provides a dust suction device for a heavy plate rolling mill to solve the problems of how to reduce dust removal costs and dust removal energy consumption.

The first sealing plate, the second sealing plate, the guiding frame and the guiding bottom plate are connected to each other and enclose a chamber. One end of the chamber communicates with the notch, and the other end communicates with a dust removal device. The dust removal device is used to form a negative pressure in the chamber so that dust enters the chamber from the notch.
[0007] Compared with the prior art, the dust suction device for a heavy plate rolling mill provided by this embodiment sets a first sealing plate on one side of the guiding frame and a second sealing plate on the other side. The first sealing plate and the second sealing plate cover the open mouth of the guiding frame, so that the first sealing plate, the second sealing plate, the guiding frame and the guiding bottom plate enclose a chamber. Such a setting is beneficial to reducing the space of the chamber, so that the dust removal device can more easily draw air in the chamber to form a negative pressure, so as to achieve the effects of reducing the dust removal cost and reducing the dust removal energy consumption.
[0008] In a possible implementation manner, the guiding bottom plate is provided with a dust collection port, the dust collection port is arranged at an interval from the notch, and the dust collection port communicates with the chamber.
[0009] In a possible implementation manner, the dust collection port is a long strip hole, and the dust collection port extends along the moving direction of the rolled material.

Detailed Embodiments
[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.
[0023] Some embodiments of the present application will be described in detail. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0024] Embodiment
[0025] Please refer to Figures 1 to 4 As shown, this embodiment provides a dust suction device 1 for a heavy plate rolling mill, which includes a guiding device 11 and a sealing member 14. The guiding device 11 includes a guiding frame 12 and a guiding bottom plate 13. The guiding frame 12 extends along the vertical direction 17, and the guiding bottom plate 13 is arranged at the bottom of the guiding frame 12. The guiding bottom plate 13 is used to correspond to the rolled material, and the guiding bottom plate 13 has a notch 131, and the notch 131 faces the rolled material. The sealing member 14 includes a first sealing plate 141 and a second sealing plate 145. The first sealing plate 141 and the second sealing plate 145 are arranged on the guiding frame 12 in opposite directions along the horizontal direction 18. The first sealing plate 141, the second sealing plate 145, the guiding frame 12 and the guiding bottom plate 13 are connected to each other and enclose a chamber 15. One end of the chamber 15 is communicated with the notch 131, and the other end is communicated with a dust removal device 16. The dust removal device 16 is used to form a negative pressure in the chamber 15 so that dust enters the chamber 15 from the notch 131.
[0026] The dust suction device 1 for the heavy plate rolling mill provided in this embodiment has a first sealing plate 141 arranged on one side of the guiding frame 12 and a second sealing plate 145 arranged on the other side. The first sealing plate 141 and the second sealing plate 145 cover the open end of the guiding frame 12, so that the first sealing plate 141, the second sealing plate 145, the guiding frame 12 and the guiding bottom plate 13 enclose a chamber 15. Such a setting is beneficial to reducing the space of the chamber 15, so that the dust removal device 16 can more easily pump air in the chamber 15 to form a negative pressure, thereby reducing the dust removal cost and dust removal energy consumption.
[0027] In this embodiment, the guiding frame 12 includes a cross beam 121, column beams 124 and rib plates 125. The cross beam 121 is spaced from the guiding bottom plate 13 along the vertical direction 17. The cross beam 121 includes a first beam plate 122 and a second beam plate 123, and the first beam plate 122 and the second beam plate 123 are spaced along the horizontal direction 18. There are two column beams 124. One column beam 124 is arranged at one end of the cross beam 121, and the other column beam 124 is arranged at the other end of the cross beam 121. The column beams 124 are fixedly connected to the cross beam 121 and the guiding bottom plate 13. The rib plate 125 is arranged between the first beam plate 122 and the second beam plate 123. One end of the rib plate 125 is fixedly connected to the cross beam 121 and the other end is fixedly connected to the guiding bottom plate 13. The rib plate 125 is used to improve the connection stability between the cross beam 121 and the guiding bottom plate 13. The cross beam 121 is used to connect a piston rod of an oil cylinder. Thus, the oil cylinder drives the cross beam 121 to move along the vertical direction 17, and the cross beam 121 moves the guiding bottom plate 13 along the vertical direction 17 through the column beams 124 and the rib plates 125, so that the guiding bottom plate 13 approaches or moves away from the rolled material.
[0028] The first beam plate 122 is spaced from the guard plate bottom plate 13 along the vertical direction 17, and the second beam plate 123 is spaced from the guard plate bottom plate 13 along the vertical direction 17 to form an opening. The first sealing plate 141 is fixedly connected to the first beam plate 122, and the first sealing plate 141 extends towards the guard plate bottom plate 13. The second sealing plate 145 is fixedly connected to the second beam plate 123, and the second sealing plate 145 extends towards the guard plate bottom plate 13. Thus, the first sealing plate 141 covers between the first beam plate 122 and the guard plate bottom plate 13, and the second sealing plate 145 covers between the second beam plate 123 and the guard plate bottom plate 13 to reduce the opening. Such a setting is beneficial to reducing the material area of the first sealing plate 141 and the second sealing plate 145 to reduce costs.
[0029] The first sealing plate 141, the first beam plate 122, the second beam plate 123, the second sealing plate 145 and the guard plate bottom plate 13 enclose to form a chamber 15. Such a setting is beneficial to reducing the space of the chamber 15, so that the dust removal device 16 can more easily extract air in the chamber 15 to form a negative pressure, thereby reducing the dust removal energy consumption.
[0030] The soot flows from the notch 131 of the guard plate bottom plate 13 into the chamber 15, and then flows from the chamber 15 into the dust removal device 16, thereby forming a dust removal path 19. The soot generated during the production of the rolled material is discharged to the outside along the dust removal path 19.
[0031] In a possible implementation manner, the guard plate bottom plate 13 is provided with a dust collection port 132. The dust collection port 132 is arranged at an interval from the notch 131, and the dust collection port 132 is communicated with the chamber 15.
[0032] In this embodiment, the notch 131 is circular. If the flow area of the circular notch 131 cannot meet the requirements of the drainage wind speed, then it is necessary to further open a dust collection port 132 on the guard plate bottom plate 13. The opening size of the dust collection port 132 meets the technical requirements of the flow field, and the arrangement form, shape and size of the dust collection port 132 can also be changed in various forms.
[0033] In a possible implementation manner, the dust collection port 132 is a long strip hole, and the dust collection port 132 extends along the moving direction of the rolled material.
[0034] In this embodiment, the rolled material generates soot during the moving process. The dust collection port 132 extends along the moving direction of the rolled material, so that the soot can be sucked into the chamber 15 from the dust collection port 132.
[0035] In a possible implementation manner, the notch 131 extends along the moving direction of the rolled material.
[0036] In this embodiment, the notch 131 is a long hole. Such a setting can, on the one hand, increase the flow area of the notch 131 to meet the requirements of the drainage wind speed, and on the other hand, the notch 131 extends along the moving direction of the rolled material so that the dust can be sucked into the chamber 15 from the notch 131.
[0037] In a possible implementation manner, the first sealing plate 141 includes a top plate 142, a first side enclosure 143 and a second side enclosure 144. The top plate 142 is arranged at an interval from the guide base plate 13. The top plate 142 is connected to the guide frame 12 along the horizontal direction 18. One end of the top plate 142 is connected to the first side enclosure 143 and the other end is connected to the second side enclosure 144 to reduce the size of the open end.
[0038] In this embodiment, the top plate 142 is arranged at one end of the first beam plate 122 close to the guide base plate 13. The top plate 142 extends towards the second beam plate 123 and the guide base plate 13 respectively. Thus, the top plate 142, the first side enclosure 143 and the second side enclosure 144 cover the first beam plate 122.
[0039] In a possible implementation manner, the second sealing plate 145 extends towards the top plate 142 along the vertical direction 17. The second sealing plate 145 is connected to the dust removal device 16.
[0040] In this embodiment, the second sealing plate 145 is arranged at one end of the second beam plate 123 close to the guide base plate 13. Thus, the second sealing plate 145 covers the second beam plate 123. The second sealing plate 145 and the first sealing plate 141 cooperate to cover the guide frame 12.
[0041] In a possible implementation manner, the dust removal device 16 includes a collection hood 161. The collection hood 161 is connected to the second sealing plate 145 and communicates with the chamber 15.
[0042] In this embodiment, the dust is sucked into the chamber 15 from the notch 131 and the dust collection port 132, and then enters the collection hood 161 from the chamber 15 to improve the capture performance of the dust suction device 1 for the thick plate rolling mill.
[0043] In a possible implementation manner, the dust removal device 16 further includes a dust removal channel 162. The dust removal channel 162 is connected to the collection hood 161. The dust removal channel 162 extends from the collection hood 161 to the outside.
[0044] In this embodiment, the dust is discharged to the outside through the dust removal channel 162 to improve the environmental quality of the operation area. The dust flows into the chamber 15 from the notch 131 of the guide base plate 13, then flows into the collection hood 161 from the chamber 15, and finally the dust is discharged to the outside through the dust removal channel 162. The dust generated during the production process of the rolled material is discharged to the outside along this dust removal path 19.
[0045] In summary, the dust collection device 1 for a heavy plate rolling mill provided in this embodiment is configured such that a first sealing plate 141 is provided on one side of the guide rack 12 and a second sealing plate 145 is provided on the other side. The first sealing plate 141 and the second sealing plate 145 cover the open ends of the guide rack 12, so that the first sealing plate 141, the second sealing plate 145, the guide rack 12 and the guide base plate 13 enclose a chamber 15. Such a setting is beneficial to reducing the space of the chamber 15, thereby making it easier for the dust removal device 16 to draw air in the chamber 15 to form a negative pressure, so as to reduce the dust removal cost and energy consumption for dust removal.
[0046] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail with reference to the above preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
