Description

Technical Field

[0001] This invention relates to the field of corrugated pipe manufacturing technology, specifically to a corrugated pipe manufacturing equipment and a double-walled corrugated pipe. Background Technology

[0002] Double-wall corrugated pipe is a composite pipe with a smooth inner wall and a corrugated outer wall. It has a unique double-layer structure design and significant performance advantages. It saves 30%-50% of raw materials compared with solid-wall pipe of the same specification, and has strong resistance to external pressure. Its ring stiffness is 2-3 times that of solid-wall pipe of the same specification. It is widely used in municipal engineering, electrical and telecommunications engineering, industry, agriculture and garden, road engineering, mining and other occasions. Its production process includes digital full-line centralized control, dual-machine co-extrusion, double-layer diversion, full vacuum belt feeding, and random flaring one-time molding.

[0003] The existing Chinese patent, application number 202210857946.4, describes a corrugated pipe processing device and method. This device and method utilizes water flow to rotate multi-branch nozzles, uniformly spraying water droplets that contact the temperature-conducting plate frame. An annular air-blowing shell then blows air upwards, effectively extending the contact time between the cooling water droplets and the temperature-conducting plate frame, allowing for thorough cooling. The airflow is then transported upwards to a pre-cooling air-blowing shell, which blows cold air onto the demolding area of ​​the corrugated pipe, achieving pre-cooling of the newly demolded corrugated pipe and effectively preventing deformation during demolding. An external drying shell continuously blows hot air, enabling the water-cooled corrugated pipe to dry quickly, allowing for direct subsequent processing.

[0004] However, in the current process of manufacturing corrugated pipes, not only is energy required for mold opening, mold closing, and demolding, but the cooling and shaping of materials also requires additional energy to drive the cooling water. This not only results in poor energy efficiency, but also fails to guarantee the efficiency and timeliness of the cooling and shaping process, often requiring secondary water cooling later. This not only increases the probability of deformation and damage when the corrugated pipe is not fully fixed, but also makes the manufacturing process of corrugated pipes consume a large amount of water resources. Summary of the Invention

[0005] This invention provides a corrugated pipe manufacturing equipment that effectively solves the problems mentioned in the background art. Currently, in the corrugated pipe manufacturing process, not only is energy required for mold opening, mold closing, and demolding, but the material cooling and shaping process also requires additional energy for driving cooling water. This not only results in poor energy saving, but also fails to guarantee the efficiency and timeliness of the cooling and shaping process, often requiring secondary water cooling later.

[0022] Compared with the prior art, the advantages of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use;

[0023] 1. Equipped with a rapid molding mechanism, the long box, inner box, shell base, turbine, impeller, toothed disc, toothed chain, and cavity work together to form an energy recovery and conversion structure. This structure can convert and utilize the heat emitted by the material during the corrugated pipe manufacturing process. On the one hand, it can turn the heat emitted by the material into driving force, realizing energy recovery and utilization, and automatically performing mold opening, mold closing, and demolding. This not only effectively eliminates dependence on external energy, making the corrugated pipe manufacturing process more continuous, efficient, and stable, but also saves the driving force required for refrigerant flow, significantly improving the effective utilization rate of equipment energy during the corrugated pipe manufacturing process, and significantly reducing the energy consumption of corrugated pipe manufacturing. While achieving energy saving and emission reduction, it also significantly reduces manufacturing costs, greatly improves economic benefits, and makes the produced corrugated pipes more competitive in the market.

[0024] On the other hand, it can use the heat emitted by the material as the initial driving force to leverage the thermal energy of the air. While further avoiding the constraints of energy on the corrugated pipe manufacturing process, it can transform passive heat dissipation into active cooling and direct water cooling into indirect dynamic refrigerant cooling. This not only effectively improves the speed and quality of cooling and shaping, ensuring the timeliness of cooling and shaping, and avoiding the trouble of subsequent secondary water cooling, but also avoids direct contact between the cooling water flow and the not fully fixed corrugated pipe, preventing water stains from adhering. While reducing processing steps and improving the convenience of subsequent processing, it can effectively improve the forming quality of the corrugated pipe. At the same time, it can eliminate the need for water resources in the corrugated pipe manufacturing process, significantly reducing water consumption and making the corrugated pipe manufacturing process more green and environmentally friendly. Through the cooperation of long pipes, short pipes, ring boxes, ring shells, mold bases, guide pipes, and valve bodies, the refrigerant can be limited and guided to form a complete refrigerant circulation loop, making the energy recovery and conversion work more efficient and stable.

[0025] 2. Equipped with a synchronous drive mechanism, the drive force is further converted through the cooperation of the rotating box, forward wheel, reverse wheel, axle, drive disc, blower seat, and impeller. In addition, the flow-limiting and guiding effect of the diverter box, sliding sleeve, and through hole can further accumulate and convert the heat energy emitted by the material and the air heat energy induced by the rapid molding mechanism, providing a more sufficient and stable driving force for the drive belt. This effectively realizes multiple utilization of air heat energy and material heat energy, making the processing of the corrugated pipe smoother and more stable, and achieving efficient and continuous production. In addition, the control function of the connecting valve, solenoid valve, and air valve can achieve dual control of the deflection speed of the drive belt.

[0026] On the one hand, the opening, closing, and demolding rates can be precisely adjusted and limited, making them more compatible with the material extrusion speed of the external extruder and the fixed shaping work of the corrugated pipe. This improves the convenience and reliability of equipment adjustment, enhances the controllability of corrugated pipe manufacturing, and makes the manufacturing process more flexible. It can meet the requirements of different material extrusion speeds for opening, closing, and demolding speeds, making the equipment suitable for more types of corrugated pipe preparation. On the other hand, it can be used in conjunction with distribution boxes, sliding sleeves, through holes, tees, four-way pipes, and filter boxes to guide external airflow, providing more stable heat exchange conditions for refrigerant circulation, improving the refrigerant circulation conversion rate, making the cooling and shaping work of the corrugated pipe more stable and efficient, and further enhancing the air heat energy that can be leveraged during refrigerant circulation, providing more sufficient driving force for the corrugated pipe manufacturing process, and further improving the reliability of the corrugated pipe manufacturing process.

[0027] In summary, this equipment can recover and convert the thermal energy of materials and air into energy multiple times during the production of corrugated pipes, reducing the dependence on external energy sources during the production process. It can also significantly increase the cooling and shaping rate of the corrugated pipes, ensure the timeliness of the shaping process, avoid the probability of deformation and damage due to untimely corrugation shaping, and greatly reduce water consumption, making the production of corrugated pipes more energy-efficient and environmentally friendly.

[0048] A synchronous drive mechanism 30 is installed on the outside of the long box 201;

[0049] The synchronous drive mechanism 30 includes a rotating box 301;

[0050] A rotating box 301 is installed at the top of the base 11.

[0054] A double-walled corrugated pipe, which is manufactured by a corrugated pipe manufacturing equipment.

[0055] The working principle and usage process of this invention: When manufacturing double-wall corrugated pipes, first, according to the site conditions, install the base 11 in the corresponding position, so that the mold cavity formed by the mold base 212 is aligned with the external extruder and screw extruder, and adjust the position of the support 1 accordingly, so that the die head of the external screw extruder can penetrate into and pull out of the mold cavity interface formed by the mold base 212 within the stroke range, thus completing the basic installation work;

[0056] After cleaning, filling and heating, the preheated screw head can be pushed into the mold cavity interface formed by the mold base 212 to start the production of double-wall corrugated pipe. The external extruder extrudes the molten material and fills the gap between the external screw head and the mold cavity formed by the mold base 212.

[0057] In the aforementioned process, after the head of the external screw compressor is pushed into the mold cavity interface formed by the mold base 212, the heat it emits will be absorbed by the R1234yf refrigerant inside the cavity 213, which will disrupt the equilibrium state of the R1234yf refrigerant inside the cavity 213. The R1234yf refrigerant inside the cavity 213 will rapidly vaporize, causing the pressure inside the cavity 213 to rise. Then, under the pushing action of the pressure and the guiding action of the valve body 215, the vaporized R1234yf refrigerant will pass through the exhaust valve 26 and enter the top ring box 210 along the conduit 214.

[0058] Subsequently, the gaseous R1234yf refrigerant will enter the housing 203 where the turbine 204 is located through the exhaust pipe, causing the turbine 204 to rotate inside the housing 203. Then, driven by the wheel axle 304, the drive disc 305 will rotate synchronously, and drive the drive belt 12 to deflect around the base 11, causing each mold base 212 to deflect synchronously around the base 11. At the same time, the impeller 307 will also rotate inside the blower seat 306 under the drive of the drive disc 305.

[0059] Then, under the traction of the impeller 307, the external airflow is filtered by the filter box 315 at the bottom of the blower seat 306 and enters the blower seat 306. It is then pressed into the diversion box 308. In the initial state, under the limit of the air pressure inside the diversion box 308, the through hole 310 and the three-way pipe 311 are in a connected state. At this time, the external airflow will pass through the through hole 310 and be pressed into the three-way pipe 311. Before the bellows manufacturing work is carried out, the solenoid valve 316 connected to the chamber where the forward impeller 302 is located or the solenoid valve 316 connected to the chamber where the reverse impeller 303 is located can be opened.

[0060] Here, taking the opening of the solenoid valve 316 connected to the chamber where the forward wheel 302 is located as an example, the external airflow will pass through the solenoid valve 316 along the three-way pipe 311 and enter the chamber where the forward wheel 302 is located, pushing the forward wheel 302 to deflect inside the rotating box 301. Under the linkage of the wheel axle 304, the external airflow driving force and the R1234yf refrigerant driving force form a combined force, jointly driving the blower seat 306 and the impeller 307 to rotate faster. The impeller 307 will then force the external airflow into the chamber where the forward wheel 302 is located at a faster speed and pressure, pushing the forward wheel 302 to rotate faster, thus forming a circulating power storage mechanism. In conjunction with the R1234yf refrigerant, it provides sufficient driving force and speed for the drive disc 305.

[0061] Similarly, when the solenoid valve 316, which is connected to the chamber where the reverse wheel 303 is located, is opened, the external airflow applies pressure to the reverse wheel 303, and the reverse wheel 303 applies a reverse force to the wheel axle 304, which hinders the deflection of the blower seat 306, counteracts part of the driving force provided by the R1234yf refrigerant, reduces the speed of the drive disc 305, and makes a preliminary adjustment to the speed of the drive disc 305 to adapt to the different requirements of the extruder base speed and the shaping and cooling speed.

[0062] Here, air can be injected into the distribution box 308 through the air valve 314 to adjust the air pressure at the end of the sliding sleeve 309. In the aforementioned process, as the impeller 307 forces the external airflow into the distribution box 308, when the pressure it applies to the sliding sleeve 309 is sufficient to offset the air pressure at the other end of the sliding sleeve 309, the sliding sleeve 309 will slide towards the air valve 314, cutting off the connection between the through hole 310 and the three-way pipe 311, and connecting the through hole 310 and the four-way pipe 312. The external airflow will directly enter the four-way pipe 312, so that the pressure of the airflow on the forward wheel 302 or the reverse wheel 303 is maintained at the set value, and the rotation speed of the drive disc 305 is precisely limited.

[0063] In the aforementioned process, after the external extruder squeezes the molten material into the cavity gap formed by the die head of the external screw and the die holder 212, the heat emitted by the molten material will also be absorbed by the R1234yf refrigerant inside the cavity 213, further increasing the internal pressure of the R1234yf refrigerant, providing sufficient driving force for the drive disc 305, driving the drive belt 12 to deflect stably, and driving each die holder 212 to perform mold opening and closing operations in a cycle;

[0064] At the same time, the R1234yf refrigerant that enters the housing 203 where the turbine 204 is located will then enter the inner box 202 through the gas supply pipe, causing the internal pressure of the inner box 202 to rise. During the flow along the continuous channel 28, it will gradually liquefy under the pressure. Subsequently, the liquefied R1234yf refrigerant will enter the housing 203 where the impeller 205 is located through the connecting pipe.

[0065] Meanwhile, driven by the toothed disc 208 and toothed chain 209, the impeller 205 will rotate at a faster speed with the turbine 204, pushing the liquid R1234yf refrigerant that enters the housing 203 where the impeller 205 is located into the bottom ring box 210 through the return pipe. Under the flow restriction effect of the return valve 27, it is sent back to each cavity 213 through the conduit 214 and the return valve 27. Then, the liquid R1234yf refrigerant will quickly vaporize again, repeating the above process.

[0066] During the aforementioned process, under the flow-limiting guidance of the connecting valve 313, the external airflow will pass through the connecting valve 313 and enter the four-way pipe 312. The airflow inside the four-way pipe 312 is forced into the gap between the long box 201 and the inner box 202 under the action of air pressure, absorbing the heat emitted when the R1234yf refrigerant liquefies, and then filtered by the activated carbon inside the filter box 315 at the top of the long box 201, carrying the heat and being discharged into the outside air.

[0067] Furthermore, in the aforementioned process, the R1234yf refrigerant rapidly absorbs the heat emitted by the molten material during the circulation process, rapidly cooling it and causing the molten material to cool and solidify rapidly inside the mold base 212. At the same time, the R1234yf refrigerant converts the absorbed heat into the driving pressure that drives the belt 12 to deflect, causing each mold base 212 to cycle through opening and closing, thus continuously producing the double-walled corrugated pipe.

[0068] After the aforementioned manufacturing process is completed, the double-walled corrugated pipe will be quickly fixed and formed. No further water cooling or heating is required. Depending on the diversified production needs, external auxiliary equipment can be used for corresponding drilling, wrapping, and cutting.

[0069] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
