Description

Technical Field

[0001] This utility model relates to the field of spiral steel pipe production technology, and more specifically, to a cooling device for spiral steel pipe production. Background Technology

[0002] Spiral steel pipe, also known as low-ribbed pipe, mainly relies on external ribs to expand the heat transfer area. It is generally used in situations where the internal heat transfer coefficient is more than twice that of the external heat transfer coefficient. Due to surface tension, it also has a good strengthening effect on external condensation and boiling. During the processing of steel pipe, heat treatment is required. After heat treatment, the steel pipe needs to be cooled before proceeding to the next process. Therefore, a cooling device for spiral steel pipe production is needed to cool the heat-treated threaded steel pipe.

[0003] Currently, the equipment used to cool spiral steel pipes involves placing the pipes inside the cooling equipment and then spraying water onto them through nozzles inside the equipment. However, this method results in the sprayed areas cooling faster than the rest of the pipe, leading to a longer cooling time and reduced production efficiency. Utility Model Content

[0024] The first motor 32 drives the transmission rod 33 to rotate, which in turn drives the first gear 34 to rotate, which in turn drives the gear chain 35 to rotate, which in turn drives the two first gears 34 to rotate synchronously, which in turn drives the two transmission rods 33 to rotate synchronously, which in turn drives the second gear 36 and the third gear 37 to rotate, which in turn drives the gear ring 38 to rotate outside the stabilizing ring 39, which can drive the nozzle 46 to rotate at a certain angle. After the part of the steel pipe has been cooled, the nozzle 46 can be moved to other positions of the steel pipe to cool the rest of the steel pipe, thereby accelerating the cooling speed of the steel pipe and improving work efficiency.

[0025] The working box 1 is equipped with a transmission component 4. The transmission component 4 includes a storage box 42 fixedly connected to the bottom of the inner cavity of the working box 1.

A water pump is fixedly connected inside the storage box 42. A transmission pipe 43 is fixedly connected to the transmission end of the water pump. The transmission pipe 43 passes through the storage box 42. An elastic hose 44 is fixedly connected to the end of the transmission pipe 43.

[0027] Water is pumped to the inside of the transmission pipe 43, then to the inside of the flexible hose 44, then to one of the transmission plates 45, and finally to the inside of the nozzle 46 via the connecting pipe 47. This process cools the steel pipe. The used water is then received by the mounting bracket 31 and transferred to the receiving pipe 41 for water recycling, thus reducing water waste.

[0031] The receiving tube 41 is equipped with a filter assembly 6. The filter assembly 6 includes a filter cylinder 61 that is slidably connected inside the receiving tube 41. A connecting ring 62 is fixedly connected to the outside of the filter cylinder 61, and a handle 63 is fixedly connected to the top of the connecting ring 62.

[0032] By allowing the water to flow freely, it passes through the filter cartridge 61, thereby filtering out impurities inside the water and ensuring that the water can be used later.

[0033] The transmission pipe 43 passes through the working box 1 and is fixedly connected.

[0034] The position of the transmission tube 43 can be restricted by the working box 1.

[0035] The working principle and usage process of this utility model are as follows: The second motor 51 drives the screw 52 to rotate, thereby driving the transmission block 53 to move, thereby driving the transmission frame 54 to move, thereby driving the slide cylinder 55 to move, thereby driving the slide rod 57 to move, thereby driving the steel pipe placed between the two slide rods 57 to move, so as to facilitate the placement of the steel pipe into the toothed ring 38.

[0036] Water is then pumped to the inside of the transmission pipe 43, which in turn pumps water to the inside of the flexible hose 44, which in turn pumps water to one of the transmission plates 45, which in turn pumps water to the inside of the other two transmission plates 45 via the connecting pipe 47, which in turn pumps water to the inside of the nozzle 46, thereby cooling the steel pipe.

[0037] Subsequently, the first motor 32 drives the transmission rod 33 to rotate, which in turn drives the first gear 34 to rotate, which in turn drives the gear chain 35 to rotate, which in turn drives the two first gears 34 to rotate synchronously, which in turn drives the two transmission rods 33 to rotate synchronously, which in turn drives the second gear 36 and the third gear 37 to rotate, which in turn drives the gear ring 38 to rotate outside the stabilizing ring 39, which can drive the nozzle 46 to rotate at a certain angle. After the part of the steel pipe has been cooled, the nozzle 46 can be moved to other positions of the steel pipe to cool the rest of the steel pipe, thereby accelerating the cooling speed of the steel pipe and improving work efficiency.
