Description

Technical Field

[0001] This utility model relates to the field of double-wave ductile plastic structure wall tube production technology, and more specifically, to a cooling device for the production of double-wave ductile plastic structure wall tubes. Background Technology

[0002] Double-walled ductile plastic (PVC) structural pipes typically refer to composite pipes made primarily of high-density polyethylene (HDPE) using a special extrusion molding process. The outer wall features a corrugated design, giving the pipe extremely high ring stiffness and compressive strength, effectively resisting external soil loads and dynamic impacts. The inner wall is smooth and flat, significantly reducing fluid resistance, improving water conveyance efficiency, and possessing excellent corrosion resistance, aging resistance, and sealing properties. With its comprehensive advantages of being lightweight, high-strength, easy to construct, and long-lasting, double-walled PVC structural pipes are widely used in municipal drainage and sewage systems, agricultural irrigation, industrial wastewater transportation, rainwater harvesting systems, and communication cable protection conduits. During the production process, cooling devices are required to cool the double-walled PVC structural pipes.

[0003] For example, Chinese Patent Publication No. CN201620156595.4 discloses a cooling device for the production of solid-walled PE pipes. The device includes a feeder, an extruder, and a die-making machine. The feeder is fixedly connected to the extruder, and the extruder is fixedly connected to the die-making machine. A cooling sleeve is fitted onto the die-making machine. The upper left and lower right ends of the cooling sleeve are respectively provided with an inlet pipe and an outlet pipe. Both the inlet and outlet pipes are connected to a cooling box via water pipes. A water pump is located above the cooling box and connected to a water pipe. The cooling box has a partition inside, dividing it into sub-chambers. A condenser pipe is located inside the cooling box, with an air outlet located on the right side of the middle section of the condenser pipe. The sub-chambers are divided into a refrigeration chamber and a heat dissipation chamber, located on the inner and outer sides of the condenser pipe, respectively. This device utilizes both air and water cooling to improve cooling efficiency and saves a significant amount of water resources through water recycling.

[0004] However, in the above-mentioned technical solutions, traditional cooling devices mostly adopt fixed-angle direct-injection air cooling or water cooling. The surface of the double-wave ductile wall is composed of alternating peaks and troughs, forming significant undulations. When using fixed-angle direct-injection cooling air, the airflow will preferentially and concentratedly impact one side of the opposite peak or trough, resulting in an extremely fast cooling rate in that area. However, the bottom of the trough or the leeward side of the peak is difficult for the airflow to reach or forms a "wind shadow zone," resulting in a significant reduction in cooling effect. This uneven cooling will generate huge local temperature differences on the same cross-section of the pipe, which will lead to stress concentration in the pipe and cause problems such as waveform deformation and decreased ring stiffness. Utility Model Content

[0005] The main objective of this invention is to provide a cooling device for the production of double-wave ductile plastic structured pipes. This device effectively solves the problem that traditional cooling devices in the background technology mostly use fixed-angle direct-injection air cooling or water cooling. The surface of the double-wave ductile plastic structured pipe is composed of alternating peaks and troughs, forming significant undulations. When using fixed-angle direct-injection cooling air, the airflow will preferentially and concentratedly impact one side of the opposite peak or trough, resulting in an extremely fast cooling rate in that area. However, the bottom of the trough or the leeward side of the peak is difficult for the airflow to reach or forms a "wind shadow zone," resulting in a significant reduction in cooling effect. This uneven cooling will generate huge local temperature differences on the same cross-section of the pipe, leading to stress concentration within the pipe and causing problems such as waveform deformation and decreased ring stiffness.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cooling device for the production of double-wave ductile plastic structure wall pipes, comprising a base, a through groove on the base, a first air delivery groove and several ball grooves on the inner wall of the through groove, a ball head in each ball groove, a second air delivery groove on each ball head, an adjusting component on one side of each ball head, an air delivery pipe fixedly installed on the outer wall of the ball head away from the first air delivery groove, an air outlet pipe threaded onto the air delivery pipe, fans fixedly installed on both sides of the base, and a third air delivery groove between the fans and the first air delivery groove.

[0007] Preferably, the first gas delivery channel is connected to the ball channel, and the two sides of the second gas delivery channel are connected to the ball channel and the gas delivery pipe, respectively.

[0008] Preferably, the airflow from the fan is delivered to the first air delivery channel through the third air delivery channel.

[0009] Preferably, the adjustment assembly has a first rotating column rotatably mounted on the base, a worm gear mounted on the first rotating column, a worm engaged on one side of the worm gear, a second rotating column fixedly mounted on one end of the worm, and a knob fixedly mounted on the end of the second rotating column away from the worm.

[0010] Preferably, one end of the first rotating column is fixedly connected to the ball head, and the worm gear is rotatably mounted on the base.

[0011] Preferably, the side of the second rotating column away from the worm gear rotates through to the outside of the base.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) When using this utility model, firstly adjust the position of the air outlet pipe according to the radius of the double-wave ductile plastic structure wall pipe, then drive the ball head to rotate through the adjustment component, and drive the air outlet pipe to rotate through the air supply pipe, so that the air outlet pipe revolves around the first rotating column. Adjust the tilt angle of the air outlet pipe according to the waveform arc of the double-wave ductile plastic structure wall pipe to ensure that the cold air blown out by the air outlet pipe evenly covers the peaks, valleys and both sides of the pipe wall, and avoids the excessive local temperature difference caused by traditional direct injection cooling.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1 to 3As shown, a cooling device for the production of double-wave ductile plastic structure wall tubes includes a base 1. A through groove 2 is provided on the base 1.

A second air delivery groove 7 is provided on the ball head 6. An adjustment component 8 is provided on one side of the ball head 6. An air delivery pipe 9 is fixedly provided on the outer wall of the side of the ball head 6 away from the first air delivery groove 3. An air outlet pipe 10 is threaded on the air delivery pipe 9. Fans 4 are fixedly installed on both sides of the base 1. A third air delivery groove 11 is provided between the fan 4 and the first air delivery groove 3.

[0021] like Figure 4 As shown, in another embodiment of the present invention, the adjusting component 8 is rotatably provided with a first rotating column 801 on the base 1, a worm gear 802 is provided on the first rotating column 801, a worm 803 is meshed on one side of the worm gear 802, a second rotating column 804 is fixedly provided on one end of the worm 803, and a knob 805 is fixedly provided on the end of the second rotating column 804 away from the worm 803.

[0022] When it is necessary to adjust the tilt angle of the air outlet pipe 10, firstly, the second rotating column 804 is rotated by the knob 805. The second rotating column 804 drives the worm gear 803 to rotate. The worm gear 803 drives the first rotating column 801 to rotate through the worm wheel 802. The first rotating column 801 drives the ball head 6 to rotate. The ball head 6 drives the air outlet pipe 10 to rotate through the air supply pipe 9, so that the air outlet pipe 10 revolves around the first rotating column 801 as the center, thereby adjusting the tilt angle of the air outlet pipe 10.

[0023] The working principle of a cooling device for the production of double-wave ductile plastic structure wall tubes:

[0024] In use, first rotate the vent pipe 10 to move it away from or towards the ball head 6. Adjust the position of the vent pipe 10 according to the radius of the double-wave ductile plastic structure. Rotate the knob 805 to rotate the second rotating column 804. The second rotating column 804 drives the worm gear 803 to rotate. The worm gear 803 drives the first rotating column 801 to rotate via the worm wheel 802. The first rotating column 801 drives the ball head 6 to rotate. The ball head 6 drives the vent pipe 10 to rotate via the air supply pipe 9. Make the vent pipe 10 revolve around the first rotating column 801 as the center. Adjust the position of the vent pipe 10 according to the waveform curvature of the double-wave ductile plastic structure. The tilt angle of the air outlet pipe 10 is adjusted to ensure that the cold air blown out by the air outlet pipe 10 evenly covers the peaks, valleys and both sides of the pipe wall. Then, the double-wave duct wall pipe passes through the through groove 2, and at the same time, the cold air generated by the fan 4 is delivered to the first air groove 3 through the third air delivery groove 11. Then, the cold air in the first air delivery groove 3 is delivered to the second air delivery groove 7 through the ball groove 5. The second air delivery groove 7 delivers the cold air to the air outlet pipe 10 through the air delivery pipe 9. Then, the cold air is blown to the double-wave duct wall pipe through the air outlet pipe 10 to cool the double-wave duct wall pipe and avoid excessive local temperature difference caused by traditional direct injection cooling.

For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
