Description

Technical Field

[0001] The utility model relates to the technical field of water cooling, in particular to a water cooling device for a variable-diameter nozzle and a water cooling system. Background Art

[0002] Metal materials usually need to be heat treated to regulate the performance of the materials. Taking titanium alloy plates as an example, titanium alloy plates after heat treatment often need to be water-cooled. Specifically, during the water-cooling treatment, multiple transport rollers need to be set up. On the one hand, they are used to unfold the titanium alloy plates for water-cooling treatment, and on the other hand, they can also transport the titanium alloy plates; wherein each transport roller is parallel to the width direction of the titanium alloy plate, and is arranged in sequence along the length direction of the titanium alloy plate; a water cooling device is arranged above and below the interval between each two adjacent transport rollers to complete the water cooling treatment of the titanium alloy plate in the width direction.

[0003] Existing water cooling devices mostly use an equal-diameter nozzle structure to achieve uniform water cooling treatment of the titanium alloy plate in the width direction. However, the heat distribution of the titanium alloy plate in the width direction after heat treatment is not uniform. The middle area in the width direction dissipates heat slowly, while the edge area in the width direction dissipates heat quickly, that is, the heat in the middle area in the width direction is higher than the heat in the edge area in the width direction; if a water cooling device with an equal-diameter nozzle is used during water cooling treatment, the heat in the middle area of ​​the titanium alloy plate will still be higher than the heat in the edge area, that is, the titanium alloy plate will be in a state of thermal imbalance in the width direction for a long time, which will eventually cause the titanium alloy plate to deform in the width direction and form a turtle back.

[0004] In summary, it is necessary to provide a variable diameter nozzle water cooling device and a water cooling system to solve the problem that the existing constant diameter nozzle water cooling device causes the titanium alloy plate to deform in the width direction and form a turtle back.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0029] Example:

[0030] See also Figure 1-Figure 3 , a variable diameter nozzle water cooling device, comprising a water storage tank 1, a water spray assembly 2 and a booster pump (not shown in the figure);

[0031] The water tank 1 is connected to an external water source through a pipeline; the booster pump is arranged on the pipeline; a plurality of rows of water spray assemblies 2 are arranged at intervals on the water tank 1; each row of the water spray assemblies 2 is arranged along the length direction of the water tank 1; each row of the water spray assemblies 2 includes a plurality of nozzles 2.1 arranged at intervals and connected to the water tank 1; in the direction from the middle area along the length direction of the water tank 1 to the edge area along the length direction of the water tank 1, the caliber of each row of the nozzles 2.1 decreases successively, so that the amount of water sprayed shows a trend of being larger in the middle and less at the edge, which can cause the heat dissipation rate of the middle area of ​​the titanium alloy plate to be faster than the heat dissipation rate of the edge area, that is, the heat in the middle area of ​​the titanium alloy plate is quickly equal to the heat in the edge area, and the problem of the existing equal-diameter nozzle water cooling device causing the titanium alloy plate to deform in the width direction and form a turtle back is solved.

[0032] See also Figure 1 The two adjacent rows of nozzles 2.1 are staggered, which, on the one hand, facilitates increasing the number of nozzles 2.1 and achieving rapid water cooling of the titanium alloy plate; on the other hand, the staggered arrangement makes the two adjacent rows of nozzles offset and complementary, and the spacing becomes smaller, so that the amount of water sprayed presents a uniform gradual trend from large in the middle to small at the edges, avoiding the occurrence of cooling troughs due to excessive spacing between adjacent nozzles, thereby causing water cooling damage to the titanium alloy plate.

[0033] See also Figure 2-Figure 3 , each row of the water spray assembly 2 also includes a water spray channel 2.2; the water spray channel 2.2 is arranged in the water storage tank 1 and is connected to the water storage tank 1; the number of the water spray channels 2.2 is the same as the number of the nozzles 2.1, and the two are connected one by one. Specifically, the nozzle 2.1 is a cylindrical structure, and the opening size of the end connected to the water spray channel 2.2 is larger than the opening size of the end away from the water spray channel 2.2; an external thread is arranged on the outer wall surface of the water spray channel 2.2; an internal thread adapted to the external thread is arranged on the inner wall surface of the nozzle 2.1, so that the nozzle 2.1 is threadedly connected to the water spray channel 2.2.

[0034] See also Figure 3 The diameter of the water spray channel 2.2 is larger than the diameter of the nozzle 2.1, so that the high-pressure water flow can be sprayed out through the nozzle 2.1 under the action of the booster pump.

[0035] See also Figure 1, the difference in the diameter of each adjacent pair of nozzles 2.1 in each row is 1mm; the center distance between each adjacent pair of nozzles 2.1 in each row is 100mm; the spacing between two adjacent rows of water spray assemblies 2 is 50mm. Specifically, the centers of each nozzle 2.1 in each row of water spray assemblies 2 are on the same straight line; the spacing between two adjacent rows of water spray assemblies 2 is the spacing between the straight lines where the centers of the nozzles 2.1 in two adjacent rows are located. The combination of a difference of 1mm, a center distance of 100mm, and a spacing of 50mm is used so that the amount of water sprayed presents a uniform gradient trend from large in the middle to small at the edges, avoiding water cooling damage to the titanium alloy plate caused by excessive gradient.

[0036] See also Figure 4 A water cooling system is used for water cooling a titanium alloy plate after heat treatment (the specifications of the titanium alloy plate are: thickness 80mm, width 2100mm, length 10000mm). During the water cooling treatment, a plurality of transport rollers 3 need to be set, each of which is parallel to the width direction of the titanium alloy plate and is arranged in sequence along the length direction of the titanium alloy plate; it is characterized in that the variable diameter nozzle water cooling device is arranged above and below the interval between each two adjacent transport rollers 3, wherein the water spraying amount of the nozzle 2.1 of the variable diameter nozzle water cooling device arranged above is 100m 3 / h, and the nozzle 2.1 of the variable-diameter nozzle water cooling device arranged below has a water spraying rate of 200m 3 / h. This is because the water sprayed by the variable diameter nozzle water cooling device arranged above stays on the titanium alloy plate for a longer time compared with the variable diameter nozzle water cooling device arranged below. Therefore, the above-mentioned water spraying amount setting can achieve equivalent water cooling treatment of the top and bottom surfaces of the titanium alloy plate; the length direction of the variable diameter nozzle water cooling device is parallel to the width direction of the titanium alloy plate, and the amount of water sprayed by the variable diameter nozzle water cooling device in the length direction shows a trend of being larger in the middle and less at the edges, which can cause the heat dissipation rate of the middle area in the width direction of the titanium alloy plate to be faster than the heat dissipation rate of the edge area, that is, the heat in the middle area of ​​the titanium alloy plate is quickly equal to the heat in the edge area, thereby solving the problem that the existing equal-diameter nozzle water cooling device causes the titanium alloy plate to deform in the width direction and form a turtle back.

[0037] By using a plurality of transport rollers 3 in combination with a plurality of the variable-diameter nozzle water cooling devices, sufficient water cooling of the titanium alloy plate from the surface to the core in the thickness direction of the plate can be achieved.

[0038] The water cooling system also includes a PLC controller (not shown in the figure); the PLC controller is connected to the booster pump in each of the variable-diameter nozzle water cooling devices to facilitate automated water cooling of the titanium alloy plate.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
