Description

Technical Field

[0001] The utility model relates to the technical field of emulsion purging devices for rolling mills, in particular to an emulsion purging device for a rolling mill. Background Art

[0002] A rolling mill is a device for realizing the metal rolling process, generally referring to the equipment for completing the whole process of rolled product production. Rolling mills can be divided into two-high, four-high, six-high, eight-high, twelve-high, eighteen-high, etc. according to the number of rolls; and can be divided into "L" type, "T" type, "F" type, "Z" type and "S" type according to the arrangement of the rolls. An ordinary rolling mill mainly consists of rolls, a frame, a roll gap adjusting device, a roll temperature adjusting device, a transmission device, a lubrication system, a control system, a roll changing device, etc.

[0003] The authorized announcement number is CN107570539A, a purging device for emulsion of cold-rolled strip steel, including a fixed base, a purging cylinder and a cleaning workbench. A main body bracket is welded on the top of the fixed base, and a conveying motor is screwed and fixed on the top of the fixed base on one side of the main body bracket through a motor base. Slide rods are welded on both sides of the inner part of the main body bracket, and a transmission screw rod is rotatably connected below the slide rods in the inner part of the main body bracket through a rotating shaft sleeve. In the present invention, first, a triangular cleaning frame is provided, and baffles are welded on the outer side of the triangular cleaning frame. The triangular cleaning frame can cooperate with the purging nozzle to guide the emulsion blown out from the surface of the strip steel into the diversion groove, and at the same time can clean the surface of the strip steel. The baffle can prevent the emulsion from splashing onto the surface of the strip steel that has been cleaned, so that the purging device for emulsion of cold-rolled strip steel is cleaner and more thorough.

[0004] However, the above patent still has deficiencies: When the steel coil is produced, both sides will be contaminated with more emulsion, and the purging range of a single purging nozzle is limited. At the same time, the purging force at a position far from the nozzle is small. Therefore, relying solely on a single purging nozzle cannot purge the emulsion on the outer surface of the steel coil cleanly, and then the emulsion will cause the steel coil to rust. Therefore, the quality of the steel coil is bound to be low. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the shortcoming that the emulsion at the far end of the steel coil cannot be purged cleanly during the production of the steel coil by the rolling mill in the prior art, and provide an emulsion purging device for a rolling mill.

[0029] As Figures 1 - 4 shown, the present invention provides a technical solution: an emulsion blowing device for a rolling mill, including: a blowing table 1, an adjusting mechanism 3 is provided inside the blowing table 1. The adjusting mechanism 3 includes a bidirectional threaded rod 31. The bidirectional threaded rod 31 penetrates through the inside of the blowing table 1. A limiting rod 32 is provided on one side surface of the bidirectional threaded rod 31. The limiting rod 32 is fixedly connected to the inner wall of the blowing table 1. Threaded sleeve blocks 33 are sleeved on the outer surfaces of the bidirectional threaded rod 31 and the limiting rod 32. A blowing mechanism 2 is provided on the threaded sleeve block 33. The number of the blowing mechanisms 2 is four. The blowing mechanism 2 includes a fixing rod 21. A rotating piece 22 is sleeved on the outer surface of the fixing rod 21. The rotating piece 22 is rotatably connected to the fixing rod 21. One end of the fixing rod 21 placed inside the rotating piece 22 is fixedly connected with an adjusting block 23. A rotating groove adapted to the adjusting block 23 is opened inside the rotating piece 22. A fixing disk 24 is fixedly connected to the outer surface of the rotating piece 22. A rotating disk 25 is provided on one side surface of the fixing disk 24. A U-shaped rod 26 penetrates through the inside of the rotating disk 25 and the fixing disk 24. The U-shaped rod 26 is slidably connected to both the rotating disk 25 and the fixing disk 24. A knob 27 is sleeved on the outer surface of one end of the U-shaped rod 26. The knob 27 is threadedly connected to the U-shaped rod 26. A connecting block 28 is fixedly connected to the outer surface of the rotating disk 25. One end of the connecting block 28 away from the rotating disk 25 is fixedly connected with a blowing cylinder 29. The output end of the blowing cylinder 29 is fixedly connected with a nozzle 201. A feeding groove 4 is opened on the blowing table 1, and a liquid leakage groove 5 is opened on the blowing table 1.

[0030] In this embodiment, by setting the blowing mechanism 2, the steel coils produced by the rolling mill can be blown in all directions, so that the emulsion on its top surface and bottom surface can be cleaned up. Since the number of the blowing mechanisms 2 is four, they can be used in pairs. By setting the adjusting block 23, the rotating piece 22 can be rotated, so that the blowing range and overlapping range of adjacent nozzles 201 can be initially adjusted. With the cooperation of the fixing disk 24 and the rotating disk 25, the blowing angle of the nozzle 201 can be in a more suitable state, so as to improve the cleaning effect of the emulsion on the outer surface of the steel coil.

[0031] In this embodiment, the threaded sleeve block 33 is threadedly connected to the bidirectional threaded rod 31, the threaded sleeve block 33 is slidably connected to the limiting rod 32, the threaded sleeve block 33 is fixedly connected to the fixed rod 21, one end of the bidirectional threaded rod 31 is sleeved with a bearing 34, and the bearing 34 is fixedly connected to both the outer surface of the bidirectional threaded rod 31 and the inner wall of the purging table 1. The end of the bidirectional threaded rod 31 away from the bearing 34 is fixedly connected to a motor 35, the outer surface of the motor 35 is sleeved with a fixing frame 36, and the fixing frame 36 is fixedly connected to both the motor 35 and the purging table 1.

[0032] In this embodiment, by providing the adjusting mechanism 3, the purging mechanism 2 can be used in cooperation. The bidirectional threaded rod 31 is used to threadedly drive the two related threaded sleeve blocks 33. Under the limitation of the limiting rod 32, the two threaded sleeve blocks 33 can move in the same and opposite directions simultaneously. Furthermore, the purging range and overlapping range of two adjacent nozzles 201 can be further adjusted.

[0033] Working principle:

[0034] As Figures 1 - 4 shown, when the present utility model is in use, according to the actual usage requirements, the usage angles of two adjacent nozzles 201 can be adjusted first. First, the purging angles of the nozzles 201 are adjusted by using the rotating disk 25 and the fixed disk 24, and the hole positions of the adjusted rotating disk 25 and fixed disk 24 are consistent. At this time, both ends of the U-shaped rod 26 are passed through the rotating disk 25 and the fixed disk 24 simultaneously, and then the knob 27 is used to tightly connect the rotating disk 25 and the fixed disk 24. Then, the rotating piece 22 is rotated. At this time, under the action of the adjusting block 23, the purging range and overlapping range of two adjacent nozzles 201 are initially adjusted. After that, the motor 35 is started. Driven by the motor 35 and restricted by the bearing 34, the bidirectional threaded rod 31 can threadedly drive the two threaded sleeve blocks 33 simultaneously, and the distance between the two nozzles 201 is adaptively adjusted according to the actual width of the steel coil until the purging range and overlapping range of two adjacent nozzles 201 can entirely cover the surface of the steel coil. At this time, the purging cylinder 29 is started to make the nozzles 201 generate purging gas, and then the steel coil is conveyed. As a result, the emulsion on the top and bottom surfaces of the steel coil can be purged and gathered together, and as the emulsion accumulates, it will automatically fall into the purging table 1 and be centrally collected through the liquid leakage groove 5.

[0035] The above is only a preferred embodiment of the present utility model, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
