Description

Technical Field

[0001] The invention relates to the technical field of corrugated pipe manufacturing, in particular to a corrugated pipe manufacturing device and a double-wall corrugated pipe. Background Art

[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 structural design and significant performance advantages. It saves 30%-50% of raw materials compared to solid-wall pipes of the same specifications. It also has strong resistance to external pressure and a ring stiffness that is 2-3 times that of solid-wall pipes of the same specifications. It is widely used in municipal engineering, electrical and telecommunications engineering, industry, agriculture and gardening, 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 expansion and one-step molding.

[0003] The existing Chinese patent, application number 202210857946.4, is a bellows processing device and a processing method thereof. The provided bellows processing device and a processing method thereof use water flow to rotate the multi-branch nozzle to evenly spray water droplets that contact the heat conducting plate frame, and the annular blowing shell blows air to form an upward airflow, effectively extending the contact time of the cooling water droplets with the heat conducting plate frame, so that the droplets are fully cooled; after the air flow moves upward and is transported to the pre-cooling blowing shell, cold air is blown to the demolding part of the bellows, so as to achieve pre-cooling of the newly demolded bellows, effectively avoiding deformation and other problems of the bellows during demolding; hot air is continuously blown out by the external air drying shell, so that the water-cooled bellows can be quickly dried, so that subsequent processing can be directly carried out;

[0004] However, in the current production process of bellows, not only energy is consumed for mold opening, mold closing and demolding, but the cooling and shaping of the material also requires additional energy to drive the cooling water. Not only is the energy-saving effect poor, the efficiency and timeliness of the cooling and shaping work are also not guaranteed, and secondary water cooling is often required in the later stage. This not only increases the probability of deformation and damage of the bellows when it is not completely fixed, but also makes the production of the bellows consume a lot of water resources.

[0022] Compared with the prior art, the present invention has the following beneficial effects: the structure of the present invention is scientific and reasonable, and the use is safe and convenient;

[0023] 1. A rapid molding mechanism is provided. Through the cooperation of the long box, inner box, shell seat, turbine, impeller, gear plate, gear chain and cavity, an energy recovery and conversion structure can be formed. The heat emitted by the material during the production of the bellows can be converted and utilized. On the one hand, the heat emitted by the material can be used as driving force to realize energy recovery and utilization, and the mold opening, mold closing and demoulding operations can be automatically performed. This not only effectively gets rid of the dependence on external energy, but also makes the preparation of the bellows more continuous, efficient and stable. At the same time, it can save the driving force required for the flow of refrigerant, greatly improve the effective utilization rate of the equipment energy in the production process of the bellows, and greatly reduce the energy consumption of the preparation of the bellows. While achieving equivalent energy conservation and emission reduction, it greatly reduces the production cost, greatly improves the economic benefits, and makes the output of the bellows 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 production of bellows, it can transform passive heat dissipation into active cooling, and transform direct water cooling into indirect refrigerant dynamic cooling. It not only effectively improves the rate and quality of cooling and shaping work, ensures the timeliness of cooling and shaping work, and avoids the trouble of subsequent secondary water cooling, but also avoids direct contact between the cooling water flow and the bellows that are not completely fixed and shaped, and avoids water stains from adhering. While reducing the processing steps and improving the convenience of subsequent processing, it can effectively improve the forming quality of the bellows. At the same time, it can get rid of the demand for water resources in the production process of the bellows, greatly reduce water resource consumption, and make the production of corrugations more green and environmentally friendly. Through the coordination of long tubes, short tubes, ring boxes, ring shells, mold bases, conduits and valve bodies, the refrigerant can be limited and guided to form a complete refrigerant circulation loop, making energy recovery and conversion more efficient and stable.

[0025] 2. A synchronous drive mechanism is provided. Through the cooperation of the rotating box, forward wheel, reverse wheel, wheel shaft, driving disc, blower seat and wind wheel, a driving force continuous conversion structure can be formed. In addition, the flow limiting and guiding function 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 pried by the rapid shaping mechanism, which can provide a more sufficient and stable driving force for the driving belt, and effectively realize the multiple utilization of air heat energy and material heat energy, making the processing of the corrugated pipe smoother and more stable, and realizing efficient and continuous production operations. In addition, the regulating function of the connecting valve, solenoid valve and air valve can realize dual regulation of the deflection speed of the driving belt;

[0026] On the one hand, the mold opening, mold closing and demolding rates can be precisely adjusted and limited to make them more compatible with the material extrusion speed of the external extruder and the fixed shaping work of the bellows, thereby improving the convenience and reliability of the equipment's adjustment, improving the controllability of the bellows production work, making the bellows production work more flexible, and meeting the requirements of the extrusion speed of materials of different materials for the mold opening, mold closing and demolding speeds, so that the equipment can be applied to more types of bellows preparation work. On the other hand, it can cooperate with the diverter box, sliding sleeve, through hole, tee pipe, four-way pipe and filter box to guide the external air flow, provide more stable heat exchange conditions for the refrigerant cycle, improve the circulation conversion rate of the refrigerant, make the cooling and shaping work of the bellows more stable and efficient, and further improve the air heat energy that can be pried during the refrigerant circulation process, provide more sufficient driving force for the bellows production work, and further improve the reliability of the bellows production work.

[0027] To sum up, in the process of making corrugated pipes, this equipment can multiple-recycle and transform the heat energy of materials and air, reduce the dependence on external energy in the process of making corrugated pipes, and greatly enhance the rate of cooling and shaping of the corrugated pipes, ensure the timeliness of fixed shaping work, 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-saving and environmentally friendly.

The distance between the connecting end of the three-way pipe 311 and the diverter box 308 and the connecting end of the four-way pipe 312 and the diverter box 308 is equal to the sliding distance of the sleeve 309, so as to accurately adjust the mold opening, mold closing and demolding speeds.

[0054] A double-wall corrugated pipe is manufactured by a device for manufacturing corrugated pipes.

[0055] The working principle and use process of the present invention are as follows: when manufacturing double-wall corrugated pipes, first, according to the on-site conditions, the base 11 is installed in the corresponding position, so that the mold cavity enclosed by the mold base 212 is aligned with the external extruder and the screw machine, and the position of the support 1 is adjusted accordingly so that the head of the external screw machine can penetrate into and pull out of the mold cavity interface enclosed by the mold base 212 within the stroke range, thereby completing the basic installation work;

[0056] After cleaning, filling, and warming up, the preheated screw machine head can be pushed into the mold cavity interface enclosed by the mold base 212 to start the production of the double-wall corrugated pipe. The external extruder squeezes out the molten material and fills it into the gap of the mold cavity enclosed by the external screw machine head and the mold base 212.

[0057] In the foregoing process, after the head of the external screw machine is pushed into the die cavity interface enclosed by the die seat 212, the heat emitted by the head will be absorbed by the R1234yf refrigerant inside the container cavity 213, thereby breaking the balance of the R1234yf refrigerant inside the container cavity 213. The R1234yf refrigerant inside the container cavity 213 rapidly vaporizes, causing the pressure inside the container cavity 213 to rise. Under the action of pressure and the flow guiding effect 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 shell seat 203 where the turbine 204 is located along the exhaust pipe, causing the turbine 204 to rotate inside the shell seat 203. Under the drive of the wheel shaft 304, the driving disc 305 will rotate synchronously, driving the drive belt 12 to deflect around the base 11, and driving each die seat 212 to deflect synchronously around the base 11. At the same time, the wind wheel 307 will also rotate inside the air blowing seat 306 under the drive of the driving disc 305;

[0059] Further, under the traction of the external airflow, after being filtered by the filter box 315 at the bottom of the air blowing seat 306, the external airflow enters the air blowing seat 306 and is then pressed into the shunt box 308. In the initial state, under the pressure limit of the shunt box 308, the through hole 310 and the three-way pipe 311 are in communication. At this time, the external airflow will pass through the through hole 310 and be pressed into the three-way pipe 311. Before the production of the corrugated pipe, the electromagnetic valve 316 connected to the chamber where the forward wheel 302 is located or the electromagnetic valve 316 connected to the chamber where the reverse wheel 303 is located can be selected to be opened;

[0060] Here, taking the opening of the electromagnetic valve 316 connected to the chamber where the forward wheel 302 is located as an example, at this time, the external airflow will pass through the electromagnetic valve 316 along the three-way pipe 311, enter the chamber where the forward wheel 302 is located, and push the forward wheel 302 to deflect inside the rotating box 301. Under the linkage of the wheel shaft 304, the external airflow pushing force and the R1234yf refrigerant pushing force form a resultant force, which together drives the air blowing seat 306 and the wind wheel 307 to rotate faster. The wind wheel 307 will press 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, thereby forming a circulating force accumulation mechanism, which cooperates with the R1234yf refrigerant to provide sufficient driving force and rotational speed for the driving disc 305;

[0061] Similarly, when the electromagnetic valve 316 connected with the chamber where the reverse wheel 303 is located is opened, the external airflow will apply pressure to the reverse wheel 303, and the reverse wheel 303 will apply a reverse force to the axle 304, impeding the deflection of the blower seat 306, offsetting part of the driving force provided by the R1234yf refrigerant, reducing the rotation speed of the driving disc 305, and preliminarily adjusting the rotation speed of the driving disc 305 to adapt to different requirements of the extruder base speed and the shaping cooling speed;

[0062] Here, the air valve 314 can be used to inject air into the distribution box 308, adjust the air pressure on the end of the sliding sleeve 309, and in the foregoing process, when the wind wheel 307 compresses the external airflow into the distribution box 308, and the pressure given to the sliding sleeve 309 is sufficient to offset the air pressure on the other end of the sliding sleeve 309, the sliding sleeve 309 will slide to the side of the air valve 314, cut off the connection between the through hole 310 and the three-way pipe 311, and connect the through hole 310 and the four-way pipe 312, so that the external airflow directly enters the four-way pipe 312, and the pressure given to the forward wheel 302 or the reverse wheel 303 by the airflow is kept at a set value, accurately limiting the rotation speed of the driving disc 305;

[0063] In the foregoing process, after the external extruder extrudes the molten material into the gap between the head of the external screw machine and the mold seat 212, the heat emitted by the molten material will also be absorbed by the R1234yf refrigerant in the container cavity 213, further increasing the internal pressure of the R1234yf refrigerant, providing sufficient driving force for the driving disc 305, driving the driving belt 12 to stably deflect, and driving each mold seat 212 to cyclically open and close the mold;

[0064] The R1234yf refrigerant entering the shell seat 203 where the turbine 204 is located will then enter the inner box 202 through the air supply pipe, causing the internal pressure of the inner box 202 to rise, and gradually liquefying under the action of pressure during the flow along the continuous channel 28. Subsequently, the liquefied R1234yf refrigerant will enter the shell seat 203 where the impeller 205 is located through the lead-in pipe;

[0065] At this time, under the drive of the toothed disc 208 and the toothed chain 209, the impeller 205 will rotate at a faster speed with the turbine 204, and the liquid R1234yf refrigerant entering the shell seat 203 where the impeller 205 is located will be compressed into the ring box 210 at the bottom through the return pipe, and under the flow limiting action of the return valve 27, it will be sent back to each container cavity 213 through the conduit 214 and the return valve 27. Subsequently, the liquid R1234yf refrigerant will be rapidly gasified again, and the foregoing process will be repeated;

[0066] And in the foregoing process, under the flow-limiting guidance of the connecting valve 313, the external airflow will pass through the connecting valve 313 into the four-way pipe 312, and the airflow inside the four-way pipe 312 will be pressed into the gap between the long box 201 and the inner box 202 under the action of air pressure, absorb the heat emitted by the R1234yf refrigerant when it is liquefied, and then carry the heat after being filtered by the activated carbon inside the filter box 315 at the top of the long box 201, and then discharged into the external air;

[0067] Further in the foregoing process, the R1234yf refrigerant rapidly absorbs the heat emitted by the molten material during the circulation process, rapidly cools it down, and promotes the molten material to rapidly cool and set in the mold seat 212, while the R1234yf refrigerant converts the absorbed heat into driving pressure to drive the deflection of the belt 12, and promotes each mold seat 212 to circulate opening and closing, and continuously produces the double-wall corrugated pipe;
