Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a cooling device for the production of insulating pipes. Background Technique

[0002] An insulating pipe is a pipe with heat insulation function used for transporting heated heavy viscous crude oil or fuel oil. Because the insulating pipe has the advantages of low project cost and energy saving, it is often used for the transportation of liquids, gases and other media, and is widely used in people's daily life.

[0003] Most of the existing cooling devices rely on the spraying method to cool down the insulating pipe. For example, a cooling device for the production of prefabricated directly buried insulating pipes disclosed in the patent application number 202021954239.X. In the above patent, the coolant is sprayed by the nozzles arranged at the top to cool down the insulating pipe. However, since the insulating pipe is always in a static state and the amount of water in contact with the insulating pipe is small, the cooling rate of the insulating pipe is slow, which affects the quality of the insulating pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Please refer to Figures 1 to 4 Figures 1 to 4 , the present utility model provides a technical solution: a cooling device for the production of thermal insulation pipes, including a cooling pool 1, and two driving rollers 2 rotatably inserted between the inner walls of the cooling pool 1. Both ends of the driving rollers 2 are coaxially and fixedly connected with driven gears 4. The driven gears 4 are located outside the cooling pool 1. A motor 5 is fixedly installed on the outer side wall of one side of the cooling pool 1. The output end of the motor 5 is fixedly connected with a driving gear 6. The driving gear 6 is meshed with the two driven gears 4 at the same time.

[0024] Place the thermal insulation pipe 14 on the two driving rollers 2, and then start the motor 5 to drive the driving gear 6 to rotate. The driving gear 6 drives the two driven gears 4 to rotate. The driven gears 4 drive the driving rollers 2 to rotate. The driving rollers 2 drive the thermal insulation pipe 14 to rotate by friction, so that the cooling water dripping from above can fully contact the surface of the thermal insulation pipe 14, thereby improving the cooling speed and ensuring the overall quality and stability of the thermal insulation pipe 14.

[0025] A spray disc 9 is arranged above the cooling pool 1. A plurality of nozzles 10 are arranged at equal distances and communicated with the bottom of the spray disc 9. A water pump 7 is fixedly installed on the rear side wall of the cooling pool 1. The water inlet end of the water pump 7 penetrates into the interior of the cooling pool 1. The water outlet end of the water pump 7 is fixedly connected with a water outlet pipe 8. The other end of the water outlet pipe 8 is communicated with the spray disc 9.

[0026] Start the water pump 7 to pump the water in the cooling pool 1 into the water outlet pipe 8, then into the interior of the spray disc 9, and finally spray out through a plurality of nozzles 10. The cooling water drops on the thermal insulation pipe 14 to achieve the purpose of cooling and temperature reduction. And the repeated use of the cooling water is realized.

[0027] A support 11 is fixedly installed on the rear side wall of the cooling pool 1. The upper end of the support 11 is fixedly connected with the spray disc 9 to realize the support of the spray disc 9 and improve the stability of the spray disc 9.

[0028] Annular grooves 201 are formed at both ends of the driving rollers 2. A plurality of blades 3 distributed circumferentially are fixedly connected to the inner walls of the annular grooves 201.

[0029] The rotating driving rollers 2 will also drive the blades 3 inside the annular grooves 201 to rotate. The blades 3 stir the cooling water inside the cooling pool 1, thereby promoting the flow of the liquid, which can significantly improve the contact effect between the cooling water and the surface of the thermal insulation pipe 14 and accelerate the volatilization of the heat of the cooling water.

[0030] A drain pipe 12 is communicated with the side wall of the cooling pool 1. A valve is arranged on the drain pipe 12. When the temperature of the liquid inside the cooling pool 1 is too high, the valve can be opened to drain the liquid through the drain pipe 12.

[0031] A plurality of heat conducting fins 13 which are fixedly connected to the inner wall of the cooling pool 1 and are equally spaced are provided. The upper ends of the heat conducting fins 13 extend to the outside of the cooling pool 1. The heat conducting fins 13 can effectively increase the heat exchange area of the inner wall of the cooling pool 1, enabling the heat to be conducted from the liquid inside the cooling pool 1 to the external environment more quickly, thereby enhancing the cooling effect.
