Description

Technical Field

[0001] This utility model relates to the field of steel plate coating production tooling technology, specifically to a color-coated steel plate coating cooling device equipped with circulating water. Background Technology

[0002] The coating process for steel plates requires baking and shaping after coating, followed by cooling of the high-temperature steel plate to facilitate the next processing step. Air cooling or water spraying is commonly used to cool the coated steel plate. However, conventional water spraying uses a single set of spray nozzles to cool the plate, and the cooling water is recycled. This results in a temperature difference of over 100°C between the high-temperature steel plate and the cooling water. Such a large temperature difference can easily cause the coating on the steel plate to crack due to rapid thermal expansion and contraction, leading to defective products. To address these issues, existing circulating water spraying cooling devices need to be improved. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a color-coated steel plate coating cooling device with circulating water. This device uses an array of cooling units to progressively cool the heated circulating water to the next layer for further cooling. This allows the steel plate requiring spray cooling to undergo multiple cooling cycles with progressively decreasing cooling intensity, thus reducing the likelihood of coating cracking. Furthermore, an external cooling system is installed to cool the initial high-temperature circulating water before recirculating it to the final stage.

[0037] The liquid inlet pipe 11 is connected to the upper connector 10 via a flange, and the inlet end of the liquid inlet pipe 11 is connected to the outlet pipe 3 on the water collection tank 2 via a flange.

[0038] The guide pipe 12 is connected to the connector 10 on the lower side via a flange, and the outlet end of the guide pipe 12 is connected to the port of the spray unit 5 on the adjacent water collection tank 2 on the right side via a flange.

[0039] The finned radiator 20 is fixedly mounted on the mounting bracket 1, and the water outlet pipe 3 on the right side of the water collection tank 2 is connected to the inlet end of the finned radiator 20 through the pipe.

[0040] The pressurizing pump 21 is fixedly mounted on the mounting bracket 1. The inlet end of the pressurizing pump 21 is connected to the outlet end of the finned radiator 20 through a pipe. The outlet end of the pressurizing pump 21 is connected to the port of the spray unit 5 on the leftmost water collection tank 2 through a pipe.

[0041] Drive shaft 14, which is spun onto motor frame 8 via bearings;

[0042] The servo motor 16 is fixedly mounted on the motor frame 8, and the output shaft of the servo motor 16 is connected to the end of the drive shaft 14 via a spline.

[0043] Guide rod 17, several guide rods 17 are fixedly mounted on drive shaft 14 in a group, and the several guide rods 17 are distributed at equal angles. The guide rods 17 are in an array and are arranged one-to-one with the peristaltic hose 13.

[0048] Guide rollers 7, two of which are arranged symmetrically on top of each other and are screwed onto the support frame 6 via bearings.

[0049] When using this device, circulating cooling water is injected into the water collection tank 2. The steel plate to be cooled is placed from the rightmost water collection tank 2 to the leftmost water collection tank 2. After the steel plate passes through the spray unit 5, it is placed between the upper and lower guide rollers 7. The spray unit 5 sprays water to cool the steel plate. The heated cooling water is guided by the guide rollers 7 and falls into the water collection tank 2. The servo motor 16 drives the drive shaft 14 to rotate. The drive shaft 14 drives the telescopic frame 18 through the guide rod 17. That is, the guide rod 17 drives the squeezing roller 15 on the telescopic frame 18 to rotate around the drive shaft 14. After the squeezing roller 15 rotates around the drive shaft 14, it abuts against the upper end of the peristaltic hose 13 and pushes it downward. Thus, the squeezing roller 15 presses the peristaltic hose 13 against the mounting base 9 and squeezes and deforms it, thereby squeezing the water in the peristaltic tube downward. The pressure pushes the circulating water in the water collection tank 2 to the peristaltic hose 13 after water is squeezed out through the water outlet pipe 3 and the liquid inlet pipe 11. The water squeezed out of the peristaltic hose 13 is sent to the spray unit 5 on the adjacent water collection tank 2 on the right through the guide pipe 12. The circulating water in the rightmost water collection tank 2 enters the finned radiator 20 for cooling and is then pumped by the pressurizing pump 21 to the spray unit 5 on the leftmost water collection tank 2. Thus, after the spray unit 5 on each water collection tank 2 sprays water to cool the steel plate, the heated circulating water is sent to the adjacent spray unit 5 on the right. This process is repeated, so that the temperature of the cooling water sprayed by the spray unit 5 from right to left decreases layer by layer from high to low. Thus, the steel plate that needs to be cooled passes from right to left, achieving cooling and temperature reduction by passing through the cooling water with a gradually decreasing temperature.

[0050] Compared with the prior art, the beneficial effects of this utility model are:

[0051] 1. This device is equipped with several water collection tanks 2, and spray units 5 are installed on the water collection tanks 2. This allows the cooled circulating water recovered in the water collection tanks 2 to be sent to the adjacent spray unit 5 on the right, and so on. This makes the temperature of the cooling water sprayed from the spray unit 5 from right to left gradually decrease, so that the steel plate that needs to be cooled can pass through from right to left, and achieve step-by-step cooling by spraying cooling water with the temperature decreasing from high to low.

[0052] 2. This device has a peristaltic hose 13 between the water outlet pipe 3 and the spray unit 5, and a squeezing roller 15 driven by a drive shaft 14. A guide rod 17 and a telescopic frame 18 are provided on the drive shaft 14 to install the squeezing roller 15. The rotation of the drive shaft 14 drives the squeezing roller 15 to rotate, and the squeezing roller 15 squeezes the peristaltic hose 13 to pump the water in the peristaltic hose 13 to the spray unit 5.

[0053] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
