Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe water spray cooling equipment, and in particular relates to a device for spraying water on the outer surface of a circular steel pipe in a surrounding manner. Background Art

[0002] At present, enterprises usually adopt the method of hot rolling perforation + continuous pipe rolling to produce round steel pipes; compared with profiles of other sections, round steel pipes have relatively high resistance to bending and torsion; in order to improve the strength and wear resistance of the outer surface of the round steel pipe, it is usually necessary to spray water on the outer surface of the round steel pipe to reduce component segregation, uniform organization and refine grains; most of the devices for spraying water on the outer surface of the round steel pipe usually adopt pipe rings. Since the pipe ring is a whole, although the water pressure inside the pipe ring is equal in the circumferential direction, there is a certain distance from the water outlet to the outer surface of the round steel pipe, and the water is subject to the gravity from the earth, and the direction of gravity is always downward. Therefore, the pressure of water reaching the outer surface of the round steel pipe is different, the pressure of water from above will increase appropriately, and the pressure of water from below will decrease appropriately, and the usual water spraying device cannot adjust the water pressure of the local fan-shaped area of ​​the pipe ring separately.

[0003] Patent document CN200620081755.X discloses a water spray quenching device for the outer surface of a red-hot steel pipe, which includes a main water pipe, a main valve, a cooling water pipe, a water collecting cylinder, a connecting rod, a base, a regulating valve, a spring, a quenching stand and a supporting wheel. Although the patented device can reuse the refluxed cooling water, the patented device can only spray water on the outer surface of the circular steel pipe from three directions. Therefore, the amount of water received by the outer surface of the circular steel pipe is very uneven. Patent document CN201910723610.7 discloses a water spray cooling device for a seamless steel pipe, which includes a fixing plate, a connecting shaft, a cooler bracket, a cold water storage tank, a water pump, a connecting seat, a support frame, a waterproof cover and a filter screen. The working efficiency of the patented device is relatively high, and multiple steel pipes can be sprayed with water for cooling, but the patented device cannot adjust the water pressure in the fan-shaped area alone. Therefore, the water pressure received by the outer surface of the circular steel pipe is also uneven. Patent document CN202121238403.1 discloses a water spray cooling device for steel pipe production with environmental protection function. The patented device includes a device body, a water storage tank, a water inlet pipe, a water pump, a water outlet pipe, a four-way water pipe, a mounting plate and a waste water tank. Although the patented device can reuse the recycled water, the patented device cannot independently adjust the water pressure in the fan-shaped area. Therefore, the water pressure on the outer surface of the circular steel pipe is also uneven. Utility Model Content

[0045] Then, another third bracket 4 is arranged on the mounting platform to ensure that the four fifth bosses 402 are located at the top, and then the two support plates 7 are turned upside down and inserted between the four fifth bosses 402 of the third bracket 4, and then the two cushion blocks 6 are inserted between the two support plates 7, and the four sixth through holes 404 of the third bracket 4, the four twelfth through holes 703 of the two support plates 7 and the two screw holes 601 of the two cushion blocks 6 are simultaneously aligned, and then the four screws 3 are successively passed through the four sixth through holes 404 and the four twelfth through holes 703, and screwed into the two screw holes 601, so that the two support plates 7, another third bracket 4 and the two cushion blocks 6 can be assembled;

In this way, the whole device is assembled and can be put into use.

[0048] The working principle of the device provided by the utility model for spraying water on the outer surface of a circular steel pipe in a surrounding manner is as follows:

[0049] Combination Figure 1 and Fig.18 As shown, since the support plate 7 is a symmetrical structure in the shape of a regular octagon, and the sixteen second bosses 202 of the eight second brackets 2 are inserted into the sixteen eleventh through holes 702 of the two support plates 7, the outer surface of the circular steel pipe 12 can receive water spray from eight directions; since the device of the utility model is designed with a symmetrical structure, and the device of the utility model matching the outer diameter specification, setting height and wall thickness specification of the circular steel pipe 12 is designed and manufactured, the sprayed water from eight directions can just form a group of water flows with uniform water volume distribution along the radial direction when reaching the outer surface of the circular steel pipe 12;

[0050] The water is affected by the downward force of gravity. The water sprayed downward is in the same direction as the gravity. The gravity serves as a motive force, which will increase the speed of the water sprayed downward to a certain extent. The water sprayed upward is in the opposite direction to the gravity. The gravity serves as a resistance, which will reduce the speed of the water sprayed upward to a certain extent. Since the water pressure determines the water spraying speed and thus the water spraying amount, in order to ensure a uniform water intake, the pressure of the water sprayed downward should be appropriately reduced and the pressure of the water sprayed upward should be appropriately increased. Since the water sprayed to the left or right is perpendicular to the direction of the gravity, the pressure of the water sprayed to the left or right remains unchanged.

[0051] The utility model provides a method for using the device for spraying water on the outer surface of a circular steel pipe in a surrounding manner:

[0052] Combination Figures 1 to 3As shown, first, the device for spraying water on the outer surface of a circular steel pipe based on a surrounding type provided by the utility model is set on a horizontal ground, and it is ensured that the two support plates 7 are directly opposite to the port of the horizontally arranged circular steel pipe 12, and then water is injected into the sixteen fourth through holes 206 of the eight second brackets 2 at the same time, and then the circular steel pipe 12 is moved backward at a uniform speed in the horizontal direction, so that the circular steel pipe 12 is inserted into the two tenth through holes 701 of the two support plates 7, and passes through the two tenth through holes 701 at a uniform speed. In this process, water can be sprayed out from the third through holes 205 of the eight surroundingly arranged second brackets 2, and the water injection pressure in the sixteen fourth through holes 206 of the eight second brackets 2 is independently controlled to ensure that the outer surface of the circular steel pipe 12 can obtain a uniform amount of water.

[0053] Supplementary explanation: The device provided by the utility model for spraying water on the outer surface of a circular steel pipe in a surrounding manner is designed with a symmetrical structure. First, according to the outer diameter specifications of the circular steel pipe, the setting height of the circular steel pipe and the wall thickness specifications of the circular steel pipe, multiple specifications of the device of the utility model should be designed and manufactured to match it.

[0054] It can be seen from the embodiments that the device for spraying water on the outer surface of a circular steel pipe based on a surrounding type provided by the utility model can achieve the purpose of uniformly spraying water on the outer surface of a horizontally moving circular steel pipe. The device of the utility model has the characteristics of low manufacturing cost, simple operation and good use effect.

[0055] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
