Description

Technical Field

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

[0002] In the industrial production sector, extruded pipes, due to their excellent plasticity, corrosion resistance, and many other superior properties, are widely used in various industries such as building water supply and drainage, municipal engineering, and chemical transportation. Market demand for these pipes continues to rise, and the requirements for production quality are becoming increasingly stringent. In the production process of extruded pipes, the cooling stage plays a crucial role, directly affecting the dimensional accuracy, mechanical properties, and appearance quality of the pipes. Improper cooling processes can easily lead to problems such as deformation, cracking, and surface roughness, severely impacting the product qualification rate.

[0003] Currently, traditional cooling devices for extruded pipes have significant limitations. These devices often struggle to precisely and rationally control the cooling water temperature, failing to create a scientific temperature gradient based on the actual needs of pipe production. For thick-walled pipes, due to their greater wall thickness and relatively slow heat dissipation, traditional devices often experience excessively rapid cooling, leading to significant internal crystallization stress and subsequent cracking, severely hindering the improvement of thick-walled pipe product quality. Furthermore, the cooling water recycling mechanism of traditional cooling devices is inadequate; cooling water is not fully and effectively recovered and reused during use, increasing water resource costs and contradicting current energy-saving and environmentally friendly production principles. For example, patent publication number CN214354075U describes a cooling device for a pipe extruder that sequentially applies air cooling and water cooling to the pipe after extrusion molding to accelerate cooling. However, in practical use, it still has some drawbacks, such as the inability to prevent crystallization stress cracking in thick-walled pipes due to excessively rapid cooling, and its low cooling water recycling rate, limiting its application. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an extruded pipe cooling device to solve the problems of low cooling water recycling rate and easy crystallization stress cracking caused by excessively rapid cooling in the prior art.

Liquid pump 2 is fixedly connected to three sides of the collecting cylinder. Liquid pump 2 is connected to mixing cylinder 1, mixing cylinder 2, and mixing cylinder 3 respectively through connecting pipes. Liquid pump 1 is fixedly connected to three sides of mixing cylinder 1, mixing cylinder 2, and mixing cylinder 3. Liquid pump 1 is connected to three cooling tanks through output pipes. Cold water inlet pipes and stirring devices are installed on collecting cylinder 1, collecting cylinder 2, collecting cylinder 3, mixing cylinder 1, mixing cylinder 2, and mixing cylinder 3. The water temperature of the three cooling tanks is adjusted by the mixing cylinders so that the front section is a strong cooling zone, the middle section is a slow cooling zone, and the rear section is a weak cooling zone. This avoids the thick-walled pipe from cracking due to crystallization stress caused by excessive cooling and makes the cooling water recycling rate higher.

[0006] The stirring device includes a motor, the output end of which is fixedly connected to a rotating shaft, and the side surface of the rotating shaft is fixedly connected to a stirring blade.

[0007] The cooling box is fixedly connected to a water circulation ring, and multiple water circulation rings are provided. The spray heads are fixedly connected to the side surface of the water circulation rings and are distributed in a ring with the spray head axis as the center.

[0008] The mixing cylinder is fixedly connected to three sides with drain pipes, which penetrate the vertical plate and extend to the other side of the vertical plate. Solenoid valves are installed on both the drain pipe and the cold water inlet pipe.

[0009] The cooling box is equipped with a connecting pipe, which is connected to multiple water rings.

[0010] The cooling box is equipped with a water distribution pipe, which is connected to the output pipe on the mixing cylinder three, and the connection is located in the middle section of the water distribution pipe. Both ends of the water distribution pipe are connected to the connecting pipe.

[0011] Water supply pipes are provided between the three cooling tanks and the first, second, and third collection cylinders, and the water supply pipes are connected to the cooling tanks, the first collection cylinder, the second collection cylinder, and the third collection cylinder.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] In the above scheme, the water temperature of the three cooling tanks is adjusted by the mixing cylinder, so that the front section is a strong cooling zone, the middle section is a slow cooling zone, and the rear section is a weak cooling zone. This avoids the thick-walled pipe from cracking due to crystallization stress caused by excessive cooling, and makes the cooling water recycling rate higher. Attached Figure Description

Cold water inlet pipe 19 and stirring device are provided on collecting cylinder 18, collecting cylinder 29, collecting cylinder 3 10, mixing cylinder 11, mixing cylinder 22, and mixing cylinder 3 13. The stirring device includes a motor 18. A rotating shaft 23 is fixedly connected to the output end of the motor 18. A stirring blade 24 is fixedly connected to the side surface of the rotating shaft 23.

[0023] A water-passing ring 6 is fixedly connected inside the cooling box 5. Multiple water-passing rings 6 are provided. Spray heads 7 are fixedly connected to the side surface of the water-passing rings 6 and are arranged in a ring around the axis of the spray heads 7. A connecting pipe 21 is provided inside the cooling box 5, and the connecting pipe 21 is connected to multiple water-passing rings 6. A water distribution pipe 17 is provided on the cooling box 5, and the water distribution pipe 17 is connected to the output pipe 16 on the mixing drum 13, with the connection point located in the middle section of the water distribution pipe 17. Both ends of the water distribution pipe 17 are connected to the connecting pipe 21 respectively. The three cooling boxes 5 are connected to the receiving... A water supply pipe 22 is installed between the first collection cylinder 8, the second collection cylinder 9, and the third collection cylinder 10. The water supply pipe 22 is connected to the cooling box 5, the first collection cylinder 8, the second collection cylinder 9, and the third collection cylinder 10. A drain pipe 14 is fixedly connected to the side surface of the third mixing cylinder 13. The drain pipe 14 passes through the vertical plate 2 and extends to the other side of the vertical plate 2. Solenoid valves 20 are installed on both the drain pipe 14 and the cold water inlet pipe 19. A control panel 4 is fixedly connected to the side surface of the vertical plate 2. The control panel 4 is electrically connected to the motor 18, the solenoid valve 20, and the second liquid pump 25.

[0024] Specifically, the extruded pipe to be cooled passes through three cooling tanks 5 in sequence. The control panel 4 starts the device, putting the motor 18, solenoid valve 20, liquid pump 15, and liquid pump 25 into operation. Liquid pump 15 operates, delivering the coolant in mixing cylinder 11, mixing cylinder 22, and mixing cylinder 33 to the water distribution pipe 17 of the cooling tank 5 through the output pipe 16. The coolant is then distributed through the water distribution pipe 17 to the connecting pipe 21, and then enters multiple water rings 6 in the cooling tank 5. Finally, it is evenly sprayed onto the surface of the pipe through the annularly distributed spray nozzles 7 to cool the pipe. After cooling, the coolant flows through the water supply pipe 22 into the corresponding collection cylinders 8, 9, and 10 for collection. Liquid pump 25 operates, transferring the collected coolant from collection cylinders 8, 9, and 10 through the connecting pipe 26. The coolant is returned to the corresponding mixing cylinders 11, 12, and 13. The motors 18 on the mixing cylinders 11, 12, and 13 drive the rotating shafts 23 and the stirring blades 24 to rotate. At the same time, the cold water inlet pipe 19 is controlled by the solenoid valve 20 to introduce new cold water, which mixes with the recovered coolant. With the help of the temperature sensors installed in the mixing cylinders 11, 12, and 13, the water temperature is adjusted to a suitable temperature. The mixed coolant is then pumped back to the cooling tank 5 by the liquid pump 15, forming a coolant recycling system. When the coolant needs to be replaced, the control panel 4 controls the solenoid valve 20 on the drain pipe 14 on the side surface of the mixing cylinder 13 to open and discharge the waste liquid. The entire process is automatically controlled by the control panel 4.

[0025] The working process of this utility model is as follows: The extruded pipe to be cooled passes through three cooling tanks 5 in sequence; the control panel 4 starts the device, causing the motor 18, solenoid valve 20, liquid pump 15, and liquid pump 25 to start working; the liquid pump 15 runs, sending the coolant in mixing cylinders 11, 22, and 33 to the water distribution pipe 17 of the cooling tank 5 through the output pipe 16; the coolant is divided by the water distribution pipe 17 to the connecting pipe 21, and then enters multiple water rings 6 in the cooling tank 5, and finally is evenly sprayed on the surface of the pipe through the annular spray head 7 to complete the cooling; the cooled coolant flows into the corresponding collection cylinders 18, 29, and 310 through the water supply pipe 22; the liquid pump 25 works, sending the coolant in the collection cylinder back to the corresponding mixing cylinder through the connecting pipe 26; the motor 18 on the mixing cylinder drives the rotating shaft 23 and the stirring blade 24 to rotate, and at the same time the cold water inlet pipe 19 is activated by the solenoid valve 20. New cold water is introduced under control and mixed with the recycled coolant. The water temperature is adjusted to a suitable value by the temperature sensor inside the mixing drum. The mixed coolant is then pumped to the cooling tank 5 by the liquid pump 15 to form a cycle. When the coolant needs to be replaced, the control panel 4 controls the solenoid valve 20 on the drain pipe 14 on the side surface of the mixing drum 13 to open and discharge the waste liquid. The entire process is automatically controlled by the control panel 4.
