Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel rolling guide devices, and in particular to a dust removal guide for a rolling mill line. Background Technology
[0002] During the production process in the steel rolling workshop, a large amount of dust is generated on the surface of the heated billet during the continuous rolling process of the rolling mill, resulting in a high dust concentration at the rolling site. This poses a significant health hazard to the workers. At the same time, the large amount of dust affects the workers' vision, making it impossible for them to clearly observe the production operation, which has a significant impact on production operation and equipment operation.
[0003] To address the aforementioned technical issues, the current conventional methods involve using axial flow fans and upper shower nozzles for dust control. Axial flow fans simply dilute the red smoke and dust into the environment quickly, while upper shower nozzles cannot form a completely enclosed space, so only a portion of the dust is carried away by the water, while some of it still dissipates into the air. Therefore, the dust removal effect is not ideal. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a dust removal guide for rolling mill lines to solve the technical problem that existing dust removal guides for steel rolling mills cannot effectively suppress dust.
[0005] To achieve the above objectives, this utility model provides a dust collector guide for a rolling mill, installed at the inlet and outlet of the rolling mill, comprising:
[0006] The guide plate has an enclosed dust removal space inside. The guide plate has a mating surface at one end near the mill roll that matches the outer contour of the mill roll. The two ends of the guide plate are open to allow the rolled workpiece to enter and exit the dust removal space. The surface of the guide plate has multiple water holes that penetrate the dust removal space. There is a gap between the inner wall of the dust removal space and the surface of the rolled workpiece to form a water flow guide space.
[0007] A water storage tank having at least one inlet and multiple outlets, wherein each outlet of the water storage tank is connected to a water passage hole on the surface of a guide plate. During operation, pressurized water entering the water storage tank is guided through the outlet and sprayed onto the surface of the rolled piece, causing the pressurized water to converge in the guide space and form a dust removal water area sufficient to completely cover the surface of the rolled piece.
[0008] As a preferred embodiment of this utility model, the guide plate is box-shaped, and the cross-section of the guide plate is a closed rectangular structure.
[0009] As a preferred technical solution of this utility model, the water passage is opened on the upper side and both sides of the dust removal space inside the guide plate.
[0010] As a preferred embodiment of this invention, all the water passages are located on the same cross section of the guide plate.
[0011] As a preferred embodiment of this utility model, the water passage hole is inclined.
[0012] As a preferred embodiment of this utility model, the water storage tank is concave, and the inner distance of the water storage tank is consistent with the outer width of the guide plate, so that the water storage tank can be locked onto the outer side of the guide plate.
[0013] As a preferred embodiment of this utility model, the water storage tank is welded and fixed to the guide plate.
[0014] As a preferred embodiment of this utility model, the water inlet of the water storage tank is a circular hole opened on its surface, and the circular hole is connected to a water pipe connector.
[0015] As a preferred embodiment of this utility model, the water pipe connector is a lever-type quick connector.
[0016] As a preferred embodiment of this utility model, the mating surface is an inclined surface so that one end of the guide plate forms a tapered structure, thereby reducing the gap between the guide plate and the surface of the rolling mill roll.
[0017] The beneficial effects of this utility model are as follows: This utility model creates a closed dust removal space inside the guide plate and water passages through the dust removal space on the surface of the guide plate, so that there is a gap between the water passages and the rolled piece to form a flow guide space. When the water supply equipment sends water into the water storage tank at a certain pressure, the water storage tank guides the water through the water outlet into the water passages and sprays it onto the surface of the rolled piece. The water gathers in the flow guide space and forms a dust removal water area that is sufficient to completely cover the surface of the rolled piece, avoiding the occurrence of dust removal dead corners, thereby effectively reducing the dust of the rolling mill and reducing the impact of dust pollution on the equipment and on-site operators.

[0030] like Figure 1-8As shown, a dust removal guide for a rolling mill is installed at the inlet and outlet of the rolling mill. It includes: a guide plate 1 with an enclosed dust removal space inside; a mating surface adapted to the outer contour of the rolling mill roll at one end of the guide plate 1 near the mill roll; openings at both ends of the guide plate 1 to allow the rolled workpiece to enter and exit the dust removal space; multiple water passage holes penetrating the dust removal space on the surface of the guide plate 1; a gap between the inner wall of the dust removal space and the surface of the rolled workpiece to form a flow space for water circulation; and a water tank 2 with at least one inlet and multiple outlets. Each outlet of the water tank 2 is connected to a water passage hole on the surface of the guide plate 1. During operation, pressurized water entering the water tank 2 is introduced through the outlet and sprayed onto the surface of the rolled workpiece, causing the pressurized water to collect in the flow space and form a dust removal water area sufficient to completely cover the surface of the rolled workpiece.
[0031] The above technical solution can effectively suppress dust generated during the rolling process. In use, the end of the guide plate 1 with the mating surface is aligned with the rolling mill roll, and the guide plate 1 is fixed on the rolling mill frame. Ensure that the guide plate 1 and the rolling mill roll maintain seamless contact as much as possible, but do not make complete contact to prevent wear on the mating surface of the guide plate 1. After the rolling mill roll sends the workpiece out, it enters the dust removal space through the opening at one end of the guide plate 1. The water supply equipment sends water into the inlet end of the water storage tank 2 at a certain pressure, so that the water accumulates inside the water storage tank 2 until it is full. The water in the water storage tank 2 is introduced into the water passage through the water outlet and sprayed onto the surface of the workpiece from the water passage. The water gathers in the guide space inside the guide plate 1 and forms a dust removal water area that is sufficient to completely cover the surface of the workpiece, avoiding dust removal dead corners. Thus, it can effectively reduce the dust of the rolling mill and reduce the impact of dust pollution on the equipment and the health of on-site operators.
[0032] like Figure 2 As shown, in this embodiment, the guide plate 1 is box-shaped, and the cross-section of the guide plate 1 is a closed rectangular structure. The guide plate 1 is formed by casting and then machining or welding. The external shape and internal cavity dimensions are designed according to the size of the rolled piece, the type of the rolling groove, and the size of the guide box.
[0033] The above technical solution can ensure that the rectangular rolled piece can be adapted to the rolling piece, so that the rolled piece can enter and exit the guide plate 1.
[0034] like Figure 2 As shown, in this embodiment, the water passages are located on the upper and both sides of the dust removal space inside the guide plate 1.
[0035] The above technical solution can ensure that water can be sprayed evenly onto the surface of the rolled piece by rationally arranging the positions of the water holes, thereby suppressing dust.
[0036] like Figure 1 and Figure 3 As shown, in this embodiment, all water passages are located on the same cross-section of the guide plate 1; the water passages are inclined.
[0037] The above technical solution allows water to splash in the guide space. When the water through the water hole sprays water onto the surface of the rolled piece at a certain incident angle, the water will bounce back to the inner wall of the guide plate 1 at a certain reflection angle. The water on the inner wall of the guide plate 1 will bounce back onto the surface of the rolled piece, thus continuously bouncing along the length of the guide plate 1. This allows the water to flow continuously in the guide space. The water collides violently with the surface of the rolled piece, effectively carrying away dust. Compared with the vertical setting of the water through the water hole, the inclined setting also allows the water to carry away the dust with a certain horizontal component force, preventing dust or iron powder from accumulating on the guide plate 1 and causing blockage, resulting in a better dust removal effect.
[0038] like Figure 4 and Figure 7 As shown, in this embodiment, the water tank 2 is concave, and the inner distance of the water tank 2 is the same as the outer width of the guide plate 1, so that the water tank 2 can be snapped onto the outer side of the guide plate 1; preferably, the water tank 2 is welded and fixed to the guide plate 1.
[0039] The above technical solution can fix the water tank 2 to the outside of the guide plate 1. That is, the water tank 2 is welded from hot-rolled steel plate, and its inner cavity size is consistent with the outer width size of the guide plate 1. The inner cavity of the water tank 2 and the guide plate 1 can fit together seamlessly, thereby covering all the water holes on the surface of the guide plate 1, improving the sealing performance and preventing water leakage.
[0040] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the water inlet of the water tank 2 is a round hole on its surface, and the round hole is connected to a water pipe connector 3; the water pipe connector 3 is a lever-type quick connector, specifically the female connector of the lever-type quick connector, which is a standard part and the appropriate model can be selected according to the actual situation.
[0041] The above technical solution allows for easy connection of the water storage tank 2 to the water supply pipe of the external water supply equipment.
[0042] like Figure 1 and Figure 8 As shown, in this embodiment, the mating surface is an inclined surface so that one end of the guide plate 1 forms a tapered structure to reduce the gap between the guide plate 1 and the surface of the rolling mill roll;
[0043] The above technical solution enables the guide plate 1 to be in close contact with the surface of the rolling mill roll, preventing dust from overflowing from the gap between them and improving the dust removal effect.
[0044] Working Principle: During use, align the mating surface of guide plate 1 with the mill roll and fix guide plate 1 to the mill frame, ensuring seamless contact between guide plate 1 and the mill roll as much as possible, but not complete contact, to prevent wear on the mating surface of guide plate 1 and to prevent dust from overflowing from the gap between them. After the mill roll delivers the workpiece, it enters the dust removal space through the opening at one end of guide plate 1. Connect the water supply pipe of the water supply equipment to the water pipe connector 3 of the water storage tank 2. The water supply equipment delivers water at a certain pressure into the inlet of the water storage tank 2, causing the water to accumulate inside the water storage tank 2 until it is full. The water in the water storage tank 2 is then introduced into the water passage through the outlet and sprayed onto the surface of the workpiece. The water collects and forms a flow space inside guide plate 1. The water area is large enough to completely cover the surface of the rolled piece, preventing dust dead zones. Due to the tilt of the water holes, the sprayed water has a certain incident angle. After the water is sprayed onto the surface of the rolled piece, the water flow will bounce back to the inner wall of the guide plate 1 at a certain reflection angle. The water flow located on the inner wall of the guide plate 1 will bounce back onto the surface of the rolled piece, thus continuously bouncing along the length of the guide plate 1. This allows the water flow to continuously circulate in the guide space. The water flow collides violently with the surface of the rolled piece, effectively carrying away dust. The tilted setting also allows the water to carry away dust with a certain horizontal component, preventing dust or iron powder from accumulating on the guide plate 1 and causing blockage. The dust removal effect is better, thus effectively reducing the dust of the rolling mill and reducing the impact of dust pollution on the equipment and the health of on-site operators.
