[0045] This invention provides a dust removal device for use in high-speed wire rod mills to treat the smoke and dust generated by the high-speed wire rod mills.

[0046] A high-speed wire rod mill includes a mill body and a protective plate surrounding the mill body. The protective plate surrounds the mill body and has an opening at the top.

[0047] like Figures 1 to 5 As shown, the dust removal device includes a dust cover 2, a pipeline assembly 3, and a spray assembly 4.

[0048] The dust cover 2 is used to cover the opening at the top of the protective plate 11. The piping assembly 3 includes a spray pipe 31 and a water supply pipe 32. The spray pipe 31 is arranged laterally inside the dust cover 2. One end of the water supply pipe 32 extends into the dust cover 2 and is connected to the spray pipe 31. The other end of the water supply pipe 32 is used to connect to a water source to supply water to the spray pipe 31.

[0049] The spray assembly 4 includes a first nozzle 41 and a second nozzle 42 disposed on the spray pipe 31. Water in the spray pipe 31 is sprayed through the first nozzle 41 and the second nozzle 42. At least one first nozzle 41 is provided and faces downward toward the mill body. Multiple second nozzles 42 are provided, distributed on opposite sides of the first nozzle 41 and facing toward the protective plate 11 on the corresponding side.

[0050] The first nozzle 41 and the second nozzle 42 capture and adsorb the dust generated by the high-speed wire rod mill by spraying water mist, and promote its settling. Combined with the sealing effect of the dust cover 2, they can effectively prevent smoke and dust from escaping, and ensure the cleanliness of the production environment and the health of the operators.

[0051] Specifically, the dust cover 2 is installed above the rolling mill body, covering the rolling mill body. The edge of the dust cover 2 extends downward, forming an opening at the bottom. The edge of the opening is used to mate with the top edge of the protective plate 11. The dust cover 2 and the protective plate 11 form a closed space, preventing the smoke and dust generated by the rolling mill body from escaping.

[0052] The first nozzle 41 is located directly above the mill body, spraying water mist downwards onto the mill body to directly cause the dust generated by the mill body to settle. The second nozzle 42 faces the protective plate 11 around the mill body, preventing dust from escaping through the gaps in the protective plate 11, thus achieving better dust removal. The positions of the first nozzle 41 and the second nozzle 42 can be set according to the position of the mill body to ensure that the water mist fully covers the mill body.

[0053] In some embodiments, the first nozzle 41 is a spiral nozzle for spraying water mist, spraying a cone-shaped water mist downwards toward the mill body, so as to concentrate and settle the smoke and dust generated by the mill body.

[0054] In some embodiments, the second nozzle 42 is a fan-shaped nozzle for spraying water mist, which sprays a flat fan-shaped water mist onto the protective plate 11 on the corresponding side. The range of the fan-shaped water mist covers the protective plate 11 laterally, preventing smoke and dust from escaping from the gaps in the protective plate 11.

[0055] The fan-shaped nozzles are distributed on the left and right sides of the spiral nozzle. The fan-shaped nozzles on the left face the left protective plate 11, and the fan-shaped nozzles on the right face the right protective plate 11. The fan-shaped water mist formed by the fan-shaped nozzles can form barriers on opposite sides of the cone-shaped water mist. A small amount of smoke and dust that is not settled by the cone-shaped water mist will be further captured by the fan-shaped water mist. Therefore, the smoke and dust have difficulty reaching the protective plate 11, which can effectively prevent the smoke and dust from escaping.

[0056] Water supply pipe 32 is connected to a water source, which can provide constant water pressure and flow rate through a water pump, control valve, etc., to ensure that the first nozzle 41 and the second nozzle 42 can produce uniform water mist. The water pump and control valve of the water source can be set to start and stop interlocked with the rolling mill body.

[0057] Furthermore, the water source is set to shut off after a delay after the mill body stops, and the water mist continues to spray for a certain period of time after the mill body stops to prevent residual smoke and dust from dissipating.

[0058] In some embodiments, multiple first nozzles 41 are provided and arranged at intervals along the length of the spray pipe 31. The spray ranges of adjacent first nozzles 41 are connected or partially overlapped to form a continuous water mist coverage area. Multiple second nozzles 42 are arranged at intervals along the length of the spray pipe 31 and are arranged on opposite sides of the first nozzles 41, forming an angle between the two second nozzles 42. The spray ranges of adjacent second nozzles 42 on the same side are connected or partially overlapped to form a continuous water mist coverage area.

[0059] like Figure 3 In the specific embodiment shown, the included angle between the two second nozzles 42 is set to 120°. In other specific embodiments, the included angle between the two second nozzles 42 can also be 90°, 110°, 150°, etc., and this utility model does not limit it in this way.

[0060] Furthermore, multiple second nozzles 42 are arranged in multiple groups, each group including at least two second nozzles 42 facing opposite protective plates 11. The multiple groups of second nozzles 42 are spaced apart on the spray pipe 31. A first nozzle 41 is disposed between two adjacent groups of second nozzles 42.

[0061] More specifically, the second nozzles 42 are grouped into groups of four, with two of the second nozzles 42 in each group positioned on the left side and close to each other, and the other two second nozzles 42 positioned on the right side and close to each other. The overlapping fan-shaped water mist ranges formed by the close-to-each-other second nozzles 42 can increase the dust suppression effect.

[0062] like Figure 4 As shown, since the water mist formed by the second nozzle 42 is a divergent fan shape, although the water mist ranges of two adjacent groups of second nozzles 42 on the same side are connected, there are still areas that cannot be completely covered. Without increasing the number of first nozzles 41 and second nozzles 42, the first nozzle 41 is arranged between two adjacent groups of second nozzles 42. The conical water mist can fill the uncovered areas between the fan-shaped water mists, so that the water mist range can more fully cover the rolling mill body, thereby fully exerting the dust suppression effect.

[0063] In some embodiments, fan-shaped nozzles are also provided at the ends of the spray pipe 31, facing the protective plate 11 corresponding to the end of the spray pipe 31. Specifically, the protective plate 11 surrounds the front, rear, left, and right sides of the rolling mill body, and a plurality of second nozzles 42 are arranged in two rows along the length of the spray pipe 31. The second nozzles 42 located at the front end of the spray pipe 31 face the front protective plate 11, the second nozzles 42 located at the rear end of the spray pipe 31 face the rear protective plate 11, and the second nozzles 42 located between the two ends of the spray pipe 31 face the corresponding left or right protective plate 11.

[0064] In some embodiments, the first nozzle 41 and / or the second nozzle 42 are detachably connected to the spray pipe 31, and the detachable connection method is, for example, fastener connection, threaded connection, snap-fit ​​connection, etc.

[0065] Specifically, the spray pipe 31 is provided with multiple mounting seats, and the first nozzle 41 or the second nozzle 42 is threadedly connected to the corresponding mounting seat. After a period of use, the first nozzle 41 or the second nozzle 42 that is clogged or worn can be removed for cleaning or replacement.

[0066] In some embodiments, one end of the spray pipe 31 and the water supply pipe 32 are fixedly connected, and the end of the water supply pipe 32 connected to the water source can be equipped with a quick-connect coupling for easy installation and disassembly. The spray pipe 31 and the water supply pipe 32 are respectively fixedly connected to the dust cover 2 to ensure stability.

[0067] Furthermore, the dust cover 2 has a through hole for the water supply pipe 32 to pass through, and the through hole is sealed to the water supply pipe 32 to prevent smoke and dust from escaping. Specifically, the water supply pipe 32 and the through hole of the dust cover 2 can be fixed and sealed with sealant. The water supply pipe 32 can be connected to a water source through a flexible hose and can move as the dust cover 2 is opened and closed.

[0068] In some implementations, such as Figure 1 and Figure 2 As shown, the bottom edge of the dust cover 2 is provided with a sealing element 5 for engaging with the top of the protective plate 11. The sealing element 5 can be an annular rubber strip, silicone strip, etc. After the dust cover 2 is closed, the sealing element 5 can seal the gap between the dust cover 2 and the top of the protective plate 11, preventing internal dust from escaping.

[0069] In some embodiments, the second nozzle 42 is directed toward the top of the corresponding protective plate 11. The second nozzle 42 is configured to start spraying water mist before the dust cover 2 is closed, which can keep the top of the protective plate 11 clean and ensure the sealing effect between the protective plate 11 and the sealant 5.

[0070] Specifically, the top of the protective plate 11 forms a flat surface, which can fit tightly against the sealing element 5. After the dust cover 2 has been open for a period of time, dust or dust from the external environment can easily fall onto the top of the protective plate 11, affecting the sealing effect of the sealing element 5. The start and stop of the first nozzle 41 and the second nozzle 42 can be controlled by a water source. The second nozzle 42 is set to spray water mist onto the top of the protective plate 11 before the dust cover 2 is closed, which can clean the top of the protective plate 11 through water mist. After the dust cover 2 is closed, it can ensure the sealing effect of the sealing element 5 and effectively prevent dust from escaping.

[0071] In some implementations, such as Figure 5 As shown, the dust cover 2 comprises two interconnected inner and outer layers, forming a closed hollow layer between them. The dust cover 2 is made of stainless steel, possessing good strength, corrosion resistance, and sealing properties. The two-layer structure further enhances the reliability of the dust cover 2. The dust cover 2 is designed with a higher center and lower edges, which helps reduce weight.

[0072] In some implementations, such as Figure 1 and Figure 2 As shown, the dust removal device also includes a lifting mechanism 6, which comprises a lifting frame 61, a connecting seat 62, and a support arm 63. The connecting seat 62 is mounted on the lifting frame 61 and is configured to move up and down under the drive of the lifting frame 61. The support arm 63 is connected to the connecting seat 62, and the dust cover 2 is fixedly connected to the support arm 63. The base of the lifting frame 61 can be fixed to concrete to ensure rigid support strength. After the lifting frame 61 is started, it can drive the dust cover 2 to move up and down through the connecting seat 62 and the support arm 63, thereby opening or closing it, which facilitates the inspection and maintenance of the rolling mill body.

[0073] Specifically, two sets of lifting mechanisms 6 can be provided, with the support arms 63 of the two sets of lifting mechanisms 6 respectively connected to opposite ends of the dust cover 2. Both sets of lifting mechanisms 6 are connected to the dust cover 2 and move synchronously. The lifting frame 61 can adopt at least one of the following: flexible transmission mechanism, gear and rack mechanism, screw and nut mechanism, pneumatic cylinder, hydraulic cylinder, and electric cylinder, to drive the connecting seat 62 to move up and down.

[0074] This utility model also provides a high-speed wire rod rolling mill, including at least one high-speed wire rod rolling mill, and the dust removal device described above.

[0075] The high-speed wire rod mill 1 includes a mill body and a protective plate 11 surrounding the mill body, with an open top on the protective plate 11. Each high-speed wire rod mill 1 is equipped with a dust removal device. The dust removal device includes a dust cover 2, a piping assembly 3, and a spray assembly 4. The dust cover 2 covers the open top of the protective plate 11, confining the dust generated by the mill body inside the dust cover 2 and the protective plate 11. The piping assembly 3 supplies water to the spray assembly 4, which sprays water mist onto the mill body and the protective plate 11, causing the dust generated by the mill body to settle and preventing it from escaping into the external environment, thus ensuring a clean production environment and the health of operators. Other specific structures, principles, and effects of the dust removal device will not be described in detail here.
