Description

Technical Field

[0001] This invention relates to the field of corrugated pipe production equipment, and more particularly to a corrugated pipe production apparatus and production process for sewage pipelines. Background Technology

[0002] Corrugated pipes for sewage, also known as double-wall corrugated pipes, are a new type of lightweight pipe made from high-density polyethylene. They are characterized by their light weight, high pressure resistance, good toughness, fast construction, and long service life. Their superior pipe wall structure design significantly reduces costs compared to other pipe structures. Furthermore, due to their convenient and reliable connections, they are widely used both domestically and internationally, largely replacing concrete and cast iron pipes.

[0003] The corrugated pipes used for wastewater pipelines have large diameters and lack matching water cooling equipment. Only after the pipeline leaves the expansion joint can an external fan be used to cool the corrugated pipe. This cooling method is too ineffective, as the corrugated pipe needs to move a certain distance in the air to complete the cooling process. During this movement, workers may be burned, posing a certain safety hazard. Summary of the Invention

Several connecting frames are evenly fixedly connected to the surface of the chain conveyor belts. Metal expansion joints are fixedly connected to the upper ends of the connecting frames. A first motor is fixedly connected to the middle and upper ends of each set of third support frames. The output end of the first motor passes through the fixed plate and is fixedly connected to the inside of the shaft.

[0014] As a further description of the above technical solution:

[0015] A manufacturing process for corrugated pipes used in sewage pipelines, wherein the manufacturing process is as follows:

[0016] Step 1: Start the second motor through the external controller. The raw material is injected into the conveying cylinder through the feed pipe. The second motor drives the fixed shaft to rotate, and the fixed shaft drives the spiral blades to rotate, conveying the raw material towards the second cooling pipe. The material is extruded from the converging port of the conveying cylinder. Part of it is between the second cooling pipe and the partition pipe, and part of it passes through the upper surface of the partition pipe. Between the partition pipe and the first cooling pipe, the extruded tubular object is pushed. The two sets of tubular objects will come into contact with each other after passing through the partition pipe. The two sets of extruded pipes will move along the first cooling pipe to the middle of the two sets of metal expansion joints.

[0017] Step Two: Water is injected into the water tank through the inlet pipe at the top. The water tank contains a refrigeration mechanism to cool the water. A second water pump transports the cold water to the first refrigeration tank inside the second cooling pipe via a set of second water pipes. The water in the first refrigeration tank then flows back into the water tank through another set of second water pipes to prevent the water in the first refrigeration tank from absorbing heat and increasing its temperature, thus reducing the cooling effect. First, close all solenoid valves on both sets of first water pipes and branch water pipes. The first water pump injects water into the three second refrigeration tanks inside the first cooling pipe through one set of first water pipes. Open the solenoid valve on the branch water pipe inserted into the first second refrigeration tank, thus injecting water into that second refrigeration tank through the branch water pipe. Once the second refrigeration tank is full, close the solenoid valve on this branch water pipe and open the solenoid valve on the next branch water pipe and the solenoid valve on the first water pipe near the previous second refrigeration tank. Cold water flows through the first water pipe... The water flows into the branch pipe inserted into the second cooling tank. Water is injected into the second cooling tank through this branch pipe. After both cooling tanks are filled with water, the solenoid valve on the branch pipe is closed, and the last solenoid valve on the first water pipe is opened. Cold water enters the last cooling tank through the first water pipe. Then, the solenoid valve on another set of first water pipes is opened to circulate the cold water in the third cooling tank and the cold water in the water tank. The first water pipe connected to the first water pump has heat sinks. When the cold water flows through the first water pipe to the third cooling tank, the heat sinks can absorb the heat from the first and second cooling tanks and transfer it to the cold water in the first water pipe, thereby reducing the water temperature in the two cooling tanks. The water temperature in the three cooling tanks gradually decreases because the corrugated pipe passes through the first cooling tank when the heat is highest. Therefore, the temperature of the pipe gradually decreases after passing through the three cooling tanks.

[0018] Step 3: Two sets of first motors drive the rotating shafts, which in turn drive the chain conveyor belts via gears. The chain conveyor belts, through connecting frames, drive the metal expansion joints, causing the metal expansion joints on the two sets of chain conveyor belts to join together in the middle to form a cylinder. This cylinder clamps the pipe that has moved along the first cooling pipe to the middle of the two sets of metal expansion joints. Several sets of metal expansion joints at the same height are connected to an external vacuum pump. The vacuum pump removes the air between the metal expansion joints and the pipe, reducing the pressure between them. This causes the outer layer of the pipe to be sucked out in raised rings, creating corrugations in the pipe. After being driven by several sets of metal expansion joints, the formed corrugated pipe is moved out from the other end of the chain conveyor belt, thus completing the production process.

[0019] The present invention has the following beneficial effects:

[0020] In this invention, a first refrigeration tank is firstly installed inside the second cooling pipe, and three second refrigeration tanks are inside the first cooling pipe. A second water pump transports cold water from the water tank to the first refrigeration tank through a second water pipe, forming a circulation between the water in the first refrigeration tank and the water in the water tank. The first refrigeration tank can cool the pipes outside the corrugated pipe. The first water pump, through the first water pipe, branch water pipes, and the cooperation of several solenoid valves, transports cold water to the three second refrigeration tanks, forming a circulation between the water in the third second refrigeration tank and the water in the water tank. When the cold water enters the third second refrigeration tank through the first water pipe, the heat sink can cool the water in the first two second refrigeration tanks, preventing the temperature inside the first two second refrigeration tanks from rising and thus reducing the cooling effect. It also prevents the temperature inside the first two second refrigeration tanks from becoming too low, which could cause the pipes to rupture due to a sudden temperature drop, and also prevents workers from being burned by the corrugated pipe.

The output end of the first motor 7 passes through the fixed plates 4 and is fixedly connected to the inside of the rotating shafts 6.

[0033] A manufacturing process for corrugated pipes used in sewage pipelines, the process flow of which is as follows:

[0034] Step 1: Start the second motor 14 through the external controller. The raw material is injected into the conveying cylinder 11 through the feed pipe 12. The second motor 14 drives the fixed shaft 20 to rotate, and the fixed shaft 20 drives the spiral blade 21 to rotate, conveying the raw material towards the second cooling pipe 22. The material is extruded from the converging port of the conveying cylinder 11. Part of it is between the second cooling pipe 22 and the partition pipe 23, and part of it passes through the upper surface of the partition pipe 23. Between the partition pipe 23 and the first cooling pipe 19, the extruded tubular object is pushed. The two sets of tubular objects will come into contact after passing through the partition pipe 23. The two sets of extruded pipes will move along the first cooling pipe 19 to the middle of the two sets of metal expansion joints 10.

[0035] Step Two: Water is injected into water tank 5 through the inlet pipe at the top of water tank 5. Water tank 5 is equipped with a refrigeration mechanism to cool the water inside. The second water pump 17 transports the cold water to the first refrigeration tank inside the second cooling pipe 22 through a set of second water pipes 18. The water in the first refrigeration tank then flows back into water tank 5 through another set of second water pipes 18 to prevent the water in the first refrigeration tank from absorbing heat and increasing its temperature, thus reducing the cooling effect. First, the connections on the two sets of first water pipes 16 and the branch water pipes 24 are closed. With solenoid valves, the first water pump 15 injects water into the three second refrigeration tanks inside the first cooling pipe 19 through a set of first water pipes 16. The solenoid valve on the branch water pipe 24 inserted into the first second refrigeration tank is opened, thus injecting water into the second refrigeration tank through the branch water pipe 24. Once the second refrigeration tank is full, the solenoid valve on this branch water pipe 24 is closed, and the solenoid valve on the next branch water pipe 24 and the solenoid valve on the first water pipe 16 closest to the previous second refrigeration tank are opened. Cold water then passes through... The first water pipe 16 flows into the branch water pipe 24 inserted into the second second refrigeration tank. Water is injected into the second second refrigeration tank through this branch water pipe 24. After both second refrigeration tanks are filled with water, the solenoid valve on the branch water pipe 24 is closed, and the last solenoid valve on the first water pipe 16 is opened. Cold water enters the last second refrigeration tank through the first water pipe 16. Then, the solenoid valve on another set of first water pipes 16 is opened to circulate the cold water in the third second refrigeration tank and the cold water in the water tank 5. The first water pipe 16, which is connected to the first water pump 15, has heat sinks 27. When the cold water flows through the first water pipe 16 to the third second refrigeration tank, the heat sinks 27 can absorb the heat from the first and second second refrigeration tanks and transfer it to the cold water in the first water pipe 16, thereby reducing the water temperature in the two second refrigeration tanks. The water temperature in the three second refrigeration tanks gradually decreases because the corrugated pipe passes through the first second refrigeration tank when the heat is highest. Therefore, the temperature of the pipe gradually decreases after passing through the three sets of second refrigeration tanks.

[0036] Step 3: Two sets of first motors 7 drive the rotating shaft 6 to rotate. The rotating shaft 6 drives the chain conveyor belt 8 to rotate through gears. The chain conveyor belt 8 drives the metal expansion joints 10 to rotate through the connecting frame 9. The metal expansion joints 10 on the two sets of chain conveyor belts 8 are spliced ​​together in the middle to form a cylinder, which clamps the pipe that has moved along the first cooling pipe 19 to the middle of the two sets of metal expansion joints 10. Several sets of metal expansion joints 10 at the same height are connected to an external vacuum pump. The vacuum pump removes the air between the metal expansion joints 10 and the pipe, reducing the pressure between the pipe and the metal expansion joints 10. This sucks out a series of protruding rings on the outer surface of the pipe, thus creating the corrugations of the pipe. After being driven by several sets of metal expansion joints 10, the formed corrugated pipe is moved out from the other end of the chain conveyor belt 8, thus completing the production.

[0037] Working principle: The second motor 14 is started by an external controller. The raw material is injected into the conveying cylinder 11 through the feed pipe 12. The second motor 14 drives the fixed shaft 20 to rotate, and the fixed shaft 20 drives the spiral blades 21 to rotate, conveying the raw material towards the second cooling pipe 22. The material is squeezed out from the converging port of the conveying cylinder 11. Part of it is between the second cooling pipe 22 and the separating pipe 23, and part of it passes through the upper surface of the separating pipe 23. Between the separating pipe 23 and the first cooling pipe 19, water is injected into the water tank 5 through the water inlet pipe at the top of the water tank 5. The water tank 5 is equipped with a refrigeration mechanism to cool the water in the water tank 5. The second water pump 17 transports the cold water to the second cooling pipe 22 through a set of second water pipes 18. In a refrigeration tank, the water in the first refrigeration tank flows back to the water tank 5 through another set of second water pipes 18. This prevents the water in the first refrigeration tank from absorbing heat and increasing its temperature, thus reducing the cooling effect. First, close all solenoid valves on the two sets of first water pipes 16 and branch water pipes 24. The first water pump 15 injects water into the three second refrigeration tanks inside the first cooling pipe 19 through a set of first water pipes 16. Open the solenoid valve on the branch water pipe 24 that is inserted into the first second refrigeration tank on the first set of first water pipes 16, thereby injecting water into the second refrigeration tank through the branch water pipe 24. Once the second refrigeration tank is full of water, close the solenoid valve on this branch water pipe 24, and open the solenoid valve on the next branch water pipe 24, as well as the solenoid valve on the first water pipe 16 near the previous second refrigeration tank. The cold water then flows through... Water flows through the first water pipe 16 to the branch water pipe 24 inserted into the second second refrigeration tank. Water is then injected into the second second refrigeration tank through this branch water pipe 24. After both second refrigeration tanks are filled with water, the solenoid valves on the branch water pipes 24 are closed, and the last solenoid valve on the first water pipe 16 is opened. Cold water enters the last second refrigeration tank through the first water pipe 16. Then, the solenoid valves on another set of first water pipes 16 are opened, causing the cold water in the third second refrigeration tank and the cold water in the water tank 5 to circulate. The first water pipe 16, which is connected to the first water pump 15, has heat sinks 27. When cold water flows through the first water pipe 16 to the third second refrigeration tank, the heat sinks 27 can absorb the heat from the first and second second refrigeration tanks and transfer it to the first water pump 15. The cold water inside water pipe 16 lowers the water temperature inside the two second refrigeration tanks. The water tanks 5 in the three second refrigeration tanks gradually decrease in temperature. Because the corrugated pipe passes through the first second refrigeration tank when the heat is highest, the temperature of the pipe gradually decreases after passing through the three sets of second refrigeration tanks. Then the extruded tubular objects are pushed, and the two sets of tubular objects will come into contact after passing through the separator pipe 23. The two sets of extruded pipes will move along the first cooling pipe 19 to the middle of the two sets of metal expansion joints 10. The two sets of first motors 7 drive the rotating shaft 6 to rotate. The rotating shaft 6 drives the chain plate conveyor belt 8 to rotate through the gear. The chain plate conveyor belt 8 drives the metal expansion joints 10 to rotate through the connecting frame 9, so that the metal expansion joints 10 on the two sets of chain plate conveyor belts 8 are spliced ​​into a cylinder in the middle.The pipe, which moves along the first cooling pipe 19, is clamped between the two sets of metal expansion joints 10. Several sets of metal expansion joints 10 at the same height are connected to an external vacuum pump. The vacuum pump removes the air between the metal expansion joints 10 and the pipe, reducing the pressure between them. This causes the outer surface of the pipe to be sucked into corrugated rings, creating the pipe's corrugations. Then, driven by the several sets of metal expansion joints 10, the formed corrugated pipe is moved from the other end of the chain conveyor belt 8, thus completing the production process.

A sealing cover is fixedly connected to one end of the feeding cylinder (11) away from the second cooling pipe (22). A mounting bracket (13) is fixedly connected to one side of the sealing cover. A second motor (14) is fixedly connected to the middle of the mounting bracket (13). A fixed shaft (20) is fixedly connected to the output end of the second motor (14). The fixed shaft (20) passes through the sealing cover and is rotatably connected to the inside of the feeding cylinder (11). A spiral blade (21) is fixedly connected to the surface of the fixed shaft (20), and the spiral blade (21) is rotatably connected to the inside of the feeding cylinder (11). A feed pipe (12) is fixedly connected to the upper part of the end of the feeding cylinder (11) close to the second motor (14), and the feed pipe (12) is connected to the inside of the feeding cylinder (11). The middle and upper ends of the four sets of third support frames (3) are all fixedly connected to fixed plates (4), and the two sets of third support frames (3) on the same side are fixedly connected to both sides of a set of fixed plates (4). The two ends of the fixed plates (4) are rotatably connected to rotating shafts (6), and the two ends of the rotating shafts (6) are fixedly connected to teeth. The two sets of rotating shafts (6) at both ends of the same set of fixed plates (4) are provided with the same set of chain conveyor belts (8), and the two sides of the chain conveyor belts (8) are provided with slots, and the slots and teeth mesh with each other. The surface of the chain conveyor belts (8) is uniformly fixedly connected to several connecting frames (9), and the upper end of the connecting frames (9) is fixedly connected to metal expansion joints (10). The middle and upper ends of the three sets of third support frames (3) are all fixedly connected to a first motor (7), and the output end of the first motor (7) passes through the fixed plate (4) and is fixedly connected to the inside of the rotating shaft (6). The production process of the corrugated pipe is as follows: Step 1: Start the second motor (14) through the external controller. The raw material is injected into the conveying cylinder (11) through the feed pipe (12). The second motor (14) drives the fixed shaft (20) to rotate. The fixed shaft (20) drives the spiral blade (21) to rotate, conveying the raw material to the direction of the second cooling pipe (22). The material is squeezed out from the converging port of the conveying cylinder (11). Part of it is between the second cooling pipe (22) and the partition pipe (23), and part of it passes through the inner surface of the partition pipe (23). Between the partition pipe (23) and the first cooling pipe (19), the extruded tubular object is pushed. The two sets of tubular objects will come into contact with each other after passing through the partition pipe (23). The two sets of extruded pipes will move along the first cooling pipe (19) to the middle of the two sets of metal expansion joints (10). Step 2: Water is injected into the water tank (5) through the inlet pipe at the top of the water tank (5). The water tank (5) is equipped with a refrigeration mechanism to cool the water in the water tank (5). The second water pump (17) transports the cold water to the first cooling tank inside the second cooling pipe (22) through a set of second water pipes (18). The water in the first cooling tank then flows back into the water tank (5) through another set of second water pipes (18) to prevent the water in the first cooling tank from absorbing heat and increasing in temperature, thus reducing the cooling effect. First, close the two sets of first water pipes (16) and branch water pipes (24). All solenoid valves, the first water pump (15) injects water into the three second cooling tanks inside the first cooling pipe (19) through a set of first water pipes (16), opens the solenoid valve on the branch water pipe (24) inserted into the first second cooling tank on the set of first water pipes (16), thereby injecting water into the second cooling tank through the branch water pipe (24), the second cooling tank is filled with water, the solenoid valve on this branch water pipe (24) is closed, the solenoid valve on the next branch water pipe (24) is opened, as well as the solenoid valve on the first water pipe (16) near the previous second cooling tank, cold water passes through the first water... Pipe (16) flows into branch water pipe (24) inserted into the second cooling tank. Water is injected into the second cooling tank through this branch water pipe (24). After both cooling tanks are filled with water, the solenoid valve on the branch water pipe (24) is closed, and the last solenoid valve on the first water pipe (16) is opened. Cold water enters the last cooling tank through the first water pipe (16). Then, the solenoid valve on another set of first water pipes (16) is opened, so that the cold water in the third cooling tank and the cold water in the water tank (5) circulate. The first water pump (15) is connected to the first water pump (15). There are heat sinks (27) on the pipe (16), and the number of heat sinks (27) in the first second cooling tank is less than the number of heat sinks (27) in the second second cooling tank. When cold water flows through the first water pipe (16) to the third second cooling tank, the heat sinks (27) can absorb the heat inside the first second cooling tank and the second second cooling tank into the cold water inside the first water pipe (16), thereby reducing the water temperature inside the two second cooling tanks. The water temperature in the three second cooling tanks gradually decreases, so that the three sets of second cooling tanks gradually reduce the heat of the pipe. Step 3: The first motor (7) drives the shaft (6) to rotate. The shaft (6) drives the chain conveyor belt (8) to rotate through the toothed gear. The chain conveyor belt (8) drives the metal expansion joint (10) to rotate through the connecting frame (9). The metal expansion joints (10) on the two sets of chain conveyor belts (8) are spliced ​​into a cylinder in the middle, which clamps the pipe that moves along the first cooling pipe (19) to the middle of the two sets of metal expansion joints (10). Several sets of metal expansion joints (10) at the same height are connected to an external vacuum pump. The vacuum pump removes the air between the metal expansion joint (10) and the pipe, reducing the pressure between the pipe and the metal expansion joint (10). This sucks out a series of protruding rings from the outer surface of the pipe, thus creating the corrugations of the pipe. After being driven by several sets of metal expansion joints (10), the formed corrugated pipe is moved out from the other end of the chain conveyor belt (8), thus completing the production.
