Abstract

The utility model belongs to the technical field of metal processing, in particular to a multi-angle spraying device for steel rolling production, which comprises a spraying operation bin and an electric control conveying track, and the spraying operation bin is provided with a spraying driving component, a secondary water guide component and an intermittent air compression nozzle; due to the fact that water flows sprayed by the downward-inclined type spray head and the vertical spray head are unidirectionally intersected along the inclined face and the vertical face respectively, the spraying face can be guaranteed, meanwhile, direct splashing generated after most of the water flows are intersected and collided is reduced, and meanwhile water sprayed to the surface of rolled steel by the downward-inclined type spray head and the vertical spray head can automatically flow to the position through the surface of the rolled steel. An electric control telescopic rod lifts a concentrated guide side plate at regular time, and water flow accumulated on the inner side of a confluence collecting groove can move towards the position where an intermittent air compression spray head is located, so that residual water confluence in the confluence collecting groove is fully subjected to pressure of the intermittent air compression spray head to be sprayed to the bottom of a steel rolling material for the second time; and then secondary spraying is carried out by utilizing the gathered water after splashing.

Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, specifically relating to a multi-angle spraying device for steel rolling production. Background Technology

[0002] Existing spraying devices suffer from uneven cooling, which can easily lead to uneven internal stress in the steel and affect quality. The main reason is the single spray angle, which prevents certain areas from cooling sufficiently, creating hot spots and ultimately causing deformation or roll wear. Current solutions address this by using spray heads at multiple angles, but the high overlap rate at the jet convergence zone easily causes jet collisions. This results in most of the water flow directly splashing after collisions, meaning the large flow rate fails to achieve adequate coverage, leading to less than ideal water utilization. Utility Model Content

[0003] This utility model provides a multi-angle spraying device for steel rolling production to solve the problems mentioned in the background art.

[0004] This utility model provides the following technical solution: a multi-angle spraying device for steel rolling production, comprising a spraying operation chamber and an electrically controlled conveying track. The spraying operation chamber is equipped with a spraying drive assembly, a secondary water guiding assembly, and intermittent air compression nozzles. The spraying drive assembly and the electrically controlled conveying track are both installed on the periphery of the spraying operation chamber. The spraying drive assembly is used to spray liquid along the arrangement path of the electrically controlled conveying track. The secondary water guiding assembly is slidably connected to the inner side of the spraying operation chamber. The intermittent air compression nozzles are fixedly connected to the inner side of the spraying operation chamber. The secondary water guiding assembly is used to guide and recover a portion of the liquid sprayed by the spraying drive assembly along the low point. The intermittent air compression nozzles are used to spray the liquid recovered by the secondary water guiding assembly along the bottom of the electrically controlled conveying track for secondary spraying.

[0005] The spray drive assembly includes a water supply pump unit, a water supply connection pipeline, and down-tilting nozzles. The water supply pump unit is fixedly connected to one side of the spray operation chamber. The down-tilting nozzles are fixedly connected to the output end of the water supply pump unit through the water supply connection pipeline. There are several down-tilting nozzles, and the several down-tilting nozzles are arranged at equal intervals on the inner side of the spray operation chamber.

[0006] The bottom of the spraying operation chamber is equipped with several vertical nozzles, which are fixedly connected to the output end of the water supply pump unit through the water supply connection pipeline.

[0007] The secondary water guiding assembly includes a centralized guiding side plate, an electrically controlled telescopic rod, and a lateral elastic sealing sleeve. The centralized guiding side plate is rotatably connected to the inside of the spray operation chamber. The output end of the electrically controlled telescopic rod is located at the bottom of the spray operation chamber. The lateral elastic sealing sleeve is fixedly connected to both ends of the centralized guiding side plate and the spray operation chamber.

[0008] The spraying operation chamber has several flow collection slots, and the electrically controlled telescopic rod and the intermittent air compressor nozzle are located inside the flow collection slots.

[0009] The electric control conveyor track is slidably connected to an inner rail conveyor frame, which is used to convey the rolled steel material to be sprayed.

[0010] The beneficial effects of this utility model are as follows: By setting up staggered downward-sloping nozzles and vertically distributed nozzles to spray the rolled steel material transported on the inner side, since the water flow from the downward-sloping nozzles and the vertical nozzles converges unidirectionally along the inclined and vertical planes respectively, the spraying surface can be guaranteed while reducing most of the splashing caused by the collision of water flow. At the same time, the water sprayed onto the surface of the rolled steel by the downward-sloping nozzles and the vertical nozzles can flow to the position by gravity on the surface of the rolled steel. After the electrically controlled telescopic rod raises the centralized guide side plate at regular intervals, the water flow accumulated inside the collection tank can move to the position of the intermittent air compression nozzle. This allows the excess water flowing inside the collection tank to be fully sprayed a second time to the bottom of the rolled steel material by the pressure of the intermittent air compression nozzle. Then, the water that has been splashed and converged is used for secondary spraying, ensuring the overall coverage effect when only vertical spraying is used on the bottom.

[0011] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0017] Please see Figures 1-4 This utility model provides the following technical solution: a multi-angle spraying device for steel rolling production, including a spraying operation chamber 1 and an electrically controlled conveying track 3. The spraying operation chamber 1 is equipped with a spraying drive assembly 2, a secondary water guiding assembly 4, and an intermittent air compression nozzle 5. The spraying drive assembly 2 and the electrically controlled conveying track 3 are both installed on the periphery of the spraying operation chamber 1. The spraying drive assembly 2 is used to spray liquid along the arrangement path of the electrically controlled conveying track 3. The secondary water guiding assembly 4 is slidably connected to the inner side of the spraying operation chamber 1. The intermittent air compression nozzle 5 is fixedly connected to the inner side of the spraying operation chamber 1. The secondary water guiding assembly 4 is used to guide and recover part of the liquid sprayed by the spraying drive assembly 2 along the low point. The intermittent air compression nozzle 5 is used to spray the liquid recovered by the secondary water guiding assembly 4 along the bottom of the electrically controlled conveying track 3 for secondary spraying.

[0018] In this embodiment, to address the problem in the prior art where the high overlap rate of the spray jet convergence area easily leads to mutual collisions between jets, resulting in most of the sprayed water directly splashing after the collision, i.e., the large spray volume cannot achieve a good spray coverage, this invention proposes a multi-angle spraying device for steel rolling production. By setting up staggered downward-sloping nozzles 23 and vertically distributed nozzles 24 to spray the steel material transported on the inner side, since the water jets sprayed from the downward-sloping nozzles 23 and the vertical nozzles 24 converge unidirectionally along the inclined and vertical planes respectively, the spray coverage can be guaranteed while reducing most of the water jets directly splashing after collision.

[0019] The spray drive assembly 2 includes a water supply pump unit 21, a water supply connection pipe 22, and a downward tilting nozzle 23. The water supply pump unit 21 is fixedly connected to one side of the spray operation chamber 1. The downward tilting nozzle 23 is fixedly connected to the output end of the water supply pump unit 21 through the water supply connection pipe 22. There are several downward tilting nozzles 23, and the several downward tilting nozzles 23 are arranged at equal intervals on the inner side of the spray operation chamber 1.

[0020] The bottom of the spray operation chamber 1 is equipped with several vertical nozzles 24, which are fixedly connected to the output end of the water supply pump unit 21 through the water supply connection pipe 22.

[0021] In this embodiment, the water supply pump unit 21 consists of a water pump and a water tank. After water is injected into the water tank, the water pump draws water and guides it through the water supply connection pipe 22 to the downward-sloping nozzle 23 and the vertical nozzle 24 to spray the steel rolling mill loaded on the rail conveyor frame 31.

[0022] The secondary water guiding assembly 4 includes a centralized guiding side plate 41, an electrically controlled telescopic rod 42, and a lateral elastic sealing sleeve 43. The centralized guiding side plate 41 is rotatably connected to the inside of the spray operation chamber 1. The output end of the electrically controlled telescopic rod 42 is located at the bottom of the spray operation chamber 1. Both ends of the centralized guiding side plate 41 are fixedly connected to the spray operation chamber 1 with the lateral elastic sealing sleeve 43.

[0023] In this embodiment, when the electrically controlled telescopic rod 42 pushes the centralized guide side plate 41 to tilt laterally, the lateral elastic sealing sleeve 43 acts to seal the rotating connection of the centralized guide side plate 41, preventing the water collected inside the collection tank 11 from flowing to the connection gap between the centralized guide side plate 41 and the electrically controlled telescopic rod 42. At the same time, the arrangement of the centralized guide side plate 41 and the electrically controlled telescopic rod 42 allows the water flowing to the inside of the collection tank 11 to stably submerge the intermittent air compression nozzle 5, so that when the intermittent air compression nozzle 5 starts to release high-pressure air, it can stably spray the water inside the collection tank 11 to the bottom of the steel rolling mill.

[0024] The spray operation chamber 1 has several collection and distribution troughs 11, and the electrically controlled telescopic rod 42 and the intermittent air compressor nozzle 5 are all located inside the collection and distribution troughs 11.

[0025] An inner conveyor frame 31 is slidably connected to the inner side of the electrically controlled conveying track 3. The inner conveyor frame 31 is used to transfer the rolled steel material to be sprayed. In this embodiment, the electrically controlled conveying track 3 is an existing electrically driven slide rail, and the inner conveyor frame 31 is connected to the transmission end of the electrically driven slide rail to realize the transfer of the rolled steel.

[0026] The working principle of this utility model is as follows: After the steel to be sprayed is loaded onto the upper end of the rail conveyor 31, the rail conveyor 31 is driven to move along its arrangement path by the electrically controlled conveying rail 3. During the movement, since the water flow sprayed from the downward-sloping nozzle 23 and the vertical nozzle 24 converges unidirectionally along the inclined and vertical planes respectively, the spraying surface can be guaranteed while reducing the direct splashing after most of the water flow converges and collides. At the same time, the water sprayed onto the surface of the steel by the downward-sloping nozzle 23 and the vertical nozzle 24 can flow to the position by gravity on the surface of the steel. The centralized guide side plate 41 is raised in a timed manner by the electrically controlled telescopic rod 42, so that the water flow accumulated inside the collection tank 11 can move to the position of the intermittent air compressed nozzle 5. The excess water in the collection tank 11 is fully sprayed to the bottom of the steel by the pressure of the intermittent air compressed nozzle 5. Then, the water that has been splashed and converged is used for secondary spraying to ensure the overall coverage effect when only vertical spraying is used at the bottom.
