Description

Technical Field

[0001] This invention relates to the technical field of anti-corrosion pipe cooling devices, and more specifically, to a 3PE anti-corrosion pipe cooling device. Background Technology

[0002] The manufacturing process of 3PE anti-corrosion pipe is as follows: First, the steel pipe is preheated, then an epoxy powder primer is sprayed, followed by the sequential winding of the adhesive layer and the polyethylene / polypropylene outer sheath. After the outer sheath is extruded and wound, it directly enters the continuous cooling stage. In this stage, the pipe needs to be rapidly cooled from the melting temperature to room temperature to achieve synchronous curing and bonding of the three layers, avoiding thermal shrinkage of the outer sheath and interlayer debonding, while ensuring that the roundness and dimensional accuracy of the anti-corrosion pipe meet the requirements.

[0003] Current cooling methods primarily target the outer wall of the pipeline, utilizing air and water cooling to achieve temperature reduction. Heat is conducted from the inner wall of the steel pipe to the outer side of the anti-corrosion layer. However, for some large-diameter, thick-walled pipelines, there are issues with excessively long heat conduction paths and large temperature differences between layers. Often, the outer sheath cools to room temperature while the inner wall of the steel pipe remains at a high temperature, making thermal stress prone to causing interlayer debonding or outer sheath shrinkage. This cooling method is not only inefficient but also results in uneven cooling, easily leading to a decline in pipeline quality.

[0004] In conclusion, the existing cooling devices have certain shortcomings and it is necessary to improve them. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] Therefore, the object of the present invention is to provide a 3PE anti-corrosion pipe cooling device, including a water collection tank, an external cooling mechanism for cooling the outer wall of the pipe, and an internal cooling mechanism for cooling the inner wall of the pipe.

[0007] The external cooling mechanism includes a cooling pipe, and a plurality of equally spaced spray heads are provided on one side of the cooling pipe.

[0008] The internal cooling mechanism consists of a left clamping assembly and a right clamping assembly. The left clamping assembly includes a horizontally movable seat with a groove on one side. A left rotating ring is embedded in the groove. The movable seat also has a first slot for inserting a water outlet pipe.

[0009] A groove is provided on one side of the movable seat, and a drying component is installed in the groove.

[0010] The right clamping assembly includes a horizontally movable right rotating ring, a fixing ring on one side of the right rotating ring, and multiple annularly distributed drainage holes on the right rotating ring.

[0011] The fixing ring is sleeved on the fixing post, and the fixing post is set on the movable plate.

[0012] The movable plate is equipped with a rotating mechanism for driving the fixed ring to rotate.

[0013] As a preferred technical solution:

[0014] As described above, in a 3PE anti-corrosion pipe cooling device, multiple sets of support rollers are provided between the external cooling mechanism and the internal cooling mechanism, and the support rollers are fixed to the water collection tank by a bracket.

[0015] Through the above technical solution, multiple sets of idlers can work together to support the pipeline, and the pipeline can also rotate axially under the action of the idlers.

[0016] As described above, in a 3PE anti-corrosion pipe cooling device, two parallel side plates are welded onto the water collection tank. The cooling pipe is horizontally arranged, and a first connecting pipe and a second connecting pipe are threaded to both ends of the cooling pipe, with one end of each connecting pipe penetrating and fixed to the side plate.

[0017] Through the above technical solution, the two side plates can support the cooling pipe through the first and second connecting pipes, ensuring that the cooling pipe remains horizontal. In this way, when the pipe rotates, the airflow or water mist sprayed by the spray head can evenly cover the surface of the pipe.

[0018] As described above, in a 3PE anti-corrosion pipe cooling device, the bottom ends of the movable seat and the movable plate are both welded and fixed with sliding seats, and the sliding seats are slidably connected to the side walls of the water collection tank.

[0019] Through the above technical solution, the sliding seat can move linearly on the water collection tank, thereby adjusting the position of the movable seat and the movable plate.

[0020] As described above, in a 3PE anti-corrosion pipe cooling device, a water pump is bolted to the sliding seat surface on the movable seat, an inlet pipe is connected to the inlet flange of the water pump, an outlet pipe is connected to the outlet flange of the water pump, and the inlet pipe extends into the water collection tank.

[0021] With the above technical solution, since the water pump adjusts its position with the sliding seat, and the water pump can always draw water from the collection tank through the inlet pipe, the movement of the sliding seat will not affect the pumping operation of the water pump.

[0022] As described above, in a 3PE anti-corrosion pipe cooling device, the left rotating ring and the right rotating ring are coaxial, the inner and outer diameters of the left rotating ring and the right rotating ring are the same, the left rotating ring is movably connected to the groove wall bearing, and the right rotating ring is welded and fixed to the fixed ring.

[0023] With the above technical solution, when the left and right rotating rings come close together, they can clamp the two ends of the pipe to fix the pipe.

[0024] As described above, in a 3PE anti-corrosion pipe cooling device, the fixed column is welded and fixed to the movable plate. The outer circular wall of the fixed column is movably connected to the inner circular bearing of the fixed ring. Both the fixed column and the movable seat are provided with a second slot. The second slots on the fixed column and the movable seat are coaxial. The second slot on the movable seat is connected to the groove.

[0025] The movable seat and the movable plate are respectively bolted with a first electric push rod and a second electric push rod, and the piston rod ends of the first electric push rod and the second electric push rod both extend into the second hole groove.

[0026] Through the above technical solution, the thrust direction of the first electric push rod and the second electric push rod can be kept in the same direction, so that the drying component can be pushed smoothly.

[0027] As described above, the 3PE anti-corrosion pipe cooling device includes a hollow outer shell with air inlets on both sides. The bottom corners of the outer shell are beveled, and a set of universal ball feet are bolted to the outer walls of the beveled sides of the outer shell.

[0028] Through the above technical solution, the universal ball support is an industrial conveying component composed of a shell and ball bearings. The universal ball support allows the drying component to move flexibly inside the pipe, and thus, through horizontal reciprocating movement, the drying operation inside the pipe can be carried out.

[0029] As described above, a 3PE anti-corrosion pipe cooling device includes a vertically arranged hot air blower inside the outer shell and an air outlet seat located below the hot air blower. Two through grooves are opened on the bottom wall of the outer shell. The air outlet seat has a hollow structure. A connection hole for connecting with the air outlet end of the hot air blower is opened at the top of the air outlet seat. The air outlet seat is generally concave. The bottom protrusion of the air outlet seat is inserted into the through groove. Spray holes are evenly opened on the outer wall of the bottom protrusion of the air outlet seat.

[0030] Through the above technical solution, the inverted "concave" design of the air outlet seat leaves space between the two through slots, and counterweights can be added as needed. The counterweights can lower the center of gravity of the drying component, so that the drying component can maintain straight movement when moving inside the rotating pipe, avoiding swaying or tipping.

[0031] A 3PE anti-corrosion pipe cooling device as described above, a micro-switch electrically connected to a hot air blower is fixed to the inner wall of the outer casing by bolts. One side of the micro-switch is provided with a "C"-shaped movable piece. The top and bottom ends of the movable piece penetrate through the wall of the outer casing, and the side wall of the movable piece is connected to the inner wall of the outer casing by a set of elastic springs.

[0032] Through the above technical solution, the movable piece is a movable structure on the outer casing, and the side surface of the movable piece is opposite to the button of the micro-switch. In this way, when the movable piece moves, it can press the button of the movable piece.

[0033] Beneficial effects:

[0034] (1) The present invention is provided with a left clamping component and a right clamping component. The left clamping component and the right clamping component can clamp the pipeline, and the pipeline can be axially rotated by a rotating mechanism, and cooperate with an external cooling mechanism to perform cooling operations on the inner and outer walls of the pipeline.

[0035] (2) A water pump is provided on the left clamping component of the present invention. The water pump can transport the cooling medium into the pipeline. In this way, the cooling medium can flow in from one end of the pipeline and flow out from the other end of the pipeline. As the pipeline rotates axially, the cooling medium can contact the wall surface of the pipeline internally at 360° without dead angles. The cooling medium directly convects and exchanges heat with the inner wall of the steel pipe, and the heat is quickly carried out by the cooling medium, which can quickly carry away the core heat storage of the thick-walled steel pipe. Cooperating with the outer wall cooling, the cooling efficiency can be greatly improved, and the quality of the pipeline is ensured.

[0036] (3) A drying component is provided on the left clamping component of the present invention. After the cooling operation is completed, under the action of the first electric push rod and the second electric push rod, the drying component can be pushed to reciprocate inside the pipeline, realizing the drying of the inside of the pipeline, avoiding water accumulation inside the pipeline. Furthermore, the device can realize the integrated operation of cooling and drying, greatly improving the service performance of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0049] like Figures 1-6 As shown in the figure, this invention discloses a 3PE anti-corrosion pipe cooling device, including a water collection tank 1, an external cooling mechanism for cooling the outer wall of the pipe, and an internal cooling mechanism for cooling the inner wall of the pipe.

[0050] Multiple sets of idler rollers 34 are also provided between the external cooling mechanism and the internal cooling mechanism. The idler rollers 34 are fixed to the water collection tank 1 by brackets 35.

[0051] The external cooling mechanism includes a cooling pipe 3, and multiple equally spaced spray nozzles 4 are provided on one side of the cooling pipe 3.

[0052] The internal cooling mechanism consists of a left clamping assembly and a right clamping assembly. The left clamping assembly includes a horizontally movable seat 7. A groove 8 is provided on one side of the movable seat 7, and a left rotating ring 9 is embedded in the groove 8. A first slot 14 for inserting the water outlet pipe 13 is provided on the movable seat 7.

[0053] A groove 15 is provided on one side of the movable seat 7, and a drying component is installed in the groove 15.

[0054] The right clamping assembly includes a horizontally movable right rotating ring 16, a fixing ring 17 on one side of the right rotating ring 16, and multiple annularly distributed drainage holes 19 on the right rotating ring 16.

[0055] The fixing ring 17 is sleeved on the fixing post 18, and the fixing post 18 is set on the movable plate 21.

[0056] The movable plate 21 is equipped with a rotating mechanism for driving the fixed ring 17 to rotate.

[0057] Specifically, during implementation, the pipe to be cooled is placed on multiple sets of idlers 34 by hoisting. Then, by moving the movable seat 7 and the right rotating ring 16, the movable seat 7 is attached to the left side of the pipe through the left rotating ring 9, and the right rotating ring 16 is attached to the right side of the pipe, thus clamping both ends of the pipe.

[0058] The rotating mechanism includes a motor mounted on the movable plate 21, a gear ring welded and fixed to the outer circular wall of the fixed ring 17, and a gear meshing with the gear ring. The motor, gear ring, and gear are not shown in the figure. The gear is fixed to the main shaft of the motor by a pin. When the motor is powered on, the gear ring can be rotated through the gear, and the fixed ring 17 can rotate accordingly. The fixed ring 17 can drive the right rotating ring 16 to rotate synchronously. In this way, the left rotating ring 9 and the right rotating ring 16 cooperate with each other to realize the axial rotation of the pipe. During the rotation, the cooling pipe 3 sprays high-speed airflow through the spray head 4, which can cool the outer wall of the rotating pipe.

[0059] After the initial cooling is complete, the cooling pipe 3 sprays water mist through the spray head 4, which can cool the outer wall of the pipe. The water mist temperature is between 40-50℃. At the same time, warm water at 40-50℃ can flow into the left side of the pipe through the outlet pipe 13. As the water flow is continuously injected, a continuous water flow is formed on the inner wall of the pipe. As the pipe rotates continuously, a water film can be formed on the inner wall of the pipe. Through convection heat transfer, the heat on the inner wall of the pipe is carried away. This simultaneous cooling of the inner and outer walls of the pipe can ensure uniform cooling and improve cooling efficiency.

[0060] After cooling is complete, the cooling pipe 3 sprays hot air at 40-50℃ through the spray head 4, which, together with the air drying component, enables the air drying of the inner and outer walls of the pipe.

[0061] When the warm water flows to the right side of the pipe, it will flow out through the drain hole 19 on the right rotating ring 16. In this way, the water mist sprayed by the spray head 4 and the warm water discharged through the drain hole 19 will eventually collect back into the water collection tank 1. The water in the water collection tank 1 can be guided into the heat exchanger to reduce the water temperature to 40-50℃ before being sent back into the water collection tank 1. In this way, the warm water in the water collection tank 1 can continuously supply the external cooling mechanism and the internal cooling mechanism, realizing water recycling.

[0062] In one specific embodiment of the present invention, two parallel side plates 2 are welded onto the water collection tank 1, and the cooling pipe 3 is horizontally arranged. The two ends of the cooling pipe 3 are respectively threaded to a first connecting pipe 5 and a second connecting pipe 6. One end of the first connecting pipe 5 and the second connecting pipe 6 are both inserted through and fixed to the side plate 2.

[0063] Specifically, such as Figure 2 As shown, valves are installed on both the first connecting pipe 5 and the second connecting pipe 6. Warm water in the water collection tank 1 can be pumped into the first connecting pipe 5 through the pump valve. The second connecting pipe 6 can be connected to a fan. When air cooling or air drying is required, the valve on the first connecting pipe 5 is closed, and when water cooling is required, the valve on the second connecting pipe 6 is closed.

[0064] Spray head 4 is a spiral-type air-liquid dual-purpose spray head, which can spray water or air separately without changing the spray head. When spraying water, it can be water-cooled, and when spraying air, it can be air-cooled or air-dried.

[0065] In one specific embodiment of the present invention, a sliding seat 10 is welded and fixed to the bottom end of both the movable seat 7 and the movable plate 21, and the sliding seat 10 is slidably connected to the two side walls of the water collection tank 1.

[0066] A water pump 11 is bolted to the surface of the sliding seat 10 on the movable seat 7. The inlet flange of the water pump 11 is connected to the inlet pipe 12, and the outlet flange of the water pump 11 is connected to the outlet pipe 13. The inlet pipe 12 extends into the water collection tank 1.

[0067] Specifically, such as Figures 1-3 As shown, the sliding seat 10 and the water collection tank 1 can slide together using a sliding rail, so that the movable seat 7 and the movable plate 21 together form a movable structure.

[0068] Both the movable seat 7 and the movable plate 21 are equipped with linear motion mechanisms, such as ball screw mechanisms or cylinder pushers, on one side plate 2. These can be selected according to requirements and are not limited here. The linear motion mechanisms are used to move the movable seat 7 and the movable plate 21.

[0069] The water pump 11 draws in the warm water in the water collection tank 1 through the water inlet pipe 12 and pumps it into the water outlet pipe 13. In this way, when the external cooling mechanism and the internal cooling mechanism clamp and rotate the pipe, the warm water can enter the inside of the pipe through the water outlet pipe 13 and flow along the pipe axis to achieve water cooling of the inner wall of the pipe.

[0070] In one specific embodiment of the present invention, the left rotating ring 9 and the right rotating ring 16 are coaxial, the inner and outer diameters of the left rotating ring 9 and the right rotating ring 16 are the same, the left rotating ring 9 is movably connected to the groove wall bearing of the groove 8, and the right rotating ring 16 is welded and fixed to the fixed ring 17.

[0071] The fixed column 18 is welded and fixed to the movable plate 21, and the outer circular wall of the fixed column 18 is movably connected to the inner circular bearing of the fixed ring 17.

[0072] Specifically, such as Figures 3-5 As shown, the left rotating ring 9 can rotate within the groove 8, while the fixed ring 17 can rotate on the fixed column 18. When the left rotating ring 9 and the right rotating ring 16 clamp the inside of the pipe, the left rotating ring 9 and the right rotating ring 16 can drive the pipe to rotate synchronously by rotating.

[0073] In one specific embodiment of the present invention, both the fixed column 18 and the movable seat 7 are provided with a second hole 20, the second hole 20 on the fixed column 18 and the movable seat 7 are coaxial, and the second hole 20 on the movable seat 7 is connected to the groove 15.

[0074] The first electric push rod 22 and the second electric push rod 23 are bolted to the movable seat 7 and the movable plate 21 respectively. The piston rod ends of the first electric push rod 22 and the second electric push rod 23 both extend into the second hole groove 20.

[0075] Specifically, such as Figures 3-5 As shown, when it is necessary to air dry the inner wall of the pipe, the first electric push rod 22 pushes the air drying component to move slowly in the groove 15 until the air drying component moves out of the groove 15 and falls onto the inner wall of the pipe.

[0076] Then, the first electric push rod 22 continues to push the drying component and apply a thrust to it, so that the drying component can move from the left side of the pipe to the right side. After moving to the right side, the second electric push rod 23 pushes the drying component again and applies a thrust to it. At this time, the drying component can move from the right side of the pipe to the left side. The first electric push rod 22 and the second electric push rod 23 cooperate with each other to realize the reciprocating movement of the drying component.

[0077] In a specific embodiment of the present invention, the air drying component includes a housing 24 with a hollow structure. Air inlet holes 25 are provided on both sides of the housing 24. The bottom corners on both sides of the housing 24 are bevel-shaped. A set of universal ball feet 30 are bolted and fixed on the outer walls of the bevels on both sides of the housing 24.

[0078] Inside the housing 24, there is a vertically arranged hot air blower 26, and an air outlet seat 27 located below the hot air blower 26. Two through slots 29 are provided on the bottom wall of the housing 24. The air outlet seat 27 has a hollow structure. A connection hole for docking with the air outlet end of the hot air blower 26 is provided at the top of the air outlet seat 27. The air outlet seat 27 is overall in an inverted "concave" shape. The protrusion at the bottom of the air outlet seat 27 is inserted into the through slot 29. Spray holes 28 are evenly provided on the outer wall of the protrusion at the bottom of the air outlet seat 27.

[0079] A microswitch 32 electrically connected to the hot air blower 26 is bolted and fixed on the inner wall of the housing 24. A "C"-shaped movable piece 31 is provided on one side of the microswitch 32. The top and bottom of the movable piece 31 pass through the wall of the housing 24. The side wall of the movable piece 31 is connected to the inner wall of the housing 24 through a set of elastic springs 33.

[0080] Specifically, as Figures 3-8 shown, when the air drying component is located in the groove 15, at this time, the groove wall in the groove 15 will squeeze the movable piece 31. At this time, the movable piece 31 does not contact the microswitch 32, and the elastic spring 33 is in a stretched state. When the air drying component is removed from the groove 15, the movable piece 31 is reset under the action of the elastic spring 33 and presses the button of the microswitch 32.

[0081] A storage battery for supplying power to the hot air blower 26 is also provided inside the housing 24. The storage battery and the hot air blower 26 are both installed by bolt fixation, which improves the overall stability. In this way, the storage battery, the hot air blower 26, and the microswitch 32 form a loop structure. When the button of the microswitch 32 is pressed, the hot air blower 26 is connected to the circuit and starts to operate. By selecting a hot air blower 26 with an appropriate power, the temperature of the air flow blown out by the hot air blower 26 is 40 - 50 °C, and the inner wall of the pipeline is air-dried by continuously blowing out heat.

[0082] The hot air blower 26 inhales air through the air inlet holes 25 and heats it into hot air. The hot air is blown into the air outlet seat 27 and finally sprayed out through the spray holes 28 on the protrusion at the bottom of the air outlet seat 27. The hot air can contact the inner wall of the pipeline and achieve the air drying operation. When the air drying component reciprocates inside the pipeline, the pipeline also rotates axially, so as to achieve uniform air drying of the inner wall of the pipeline.

[0083] A plurality of rubber shock pads are also provided on both sides of the housing 24 to avoid violent impacts during the movement process.

[0084] Assuming the overall weight of the air-drying assembly is 10KG, the air-drying assembly can move inside the pipe via the universal ball joint 30. Since the universal ball joint 30 and the inner wall of the pipe are subject to rolling friction, the coefficient of rolling friction is much smaller than that of sliding friction. Furthermore, the inner wall of the 3PE anti-corrosion steel pipe is coated with polyethylene, with a smooth and burr-free surface and an extremely low coefficient of friction. For large-diameter thick-walled 3PE pipes, a standard length of 12m is the industry mainstream, with a typical range of 6-12m. Here, we will use 10m as an example for illustration.

[0085] To ensure stable reciprocating movement of the drying assembly within a 10m duct, suitable models of the first electric actuator 22 and the second electric actuator 23 are required. The normal force N exerted by the drying assembly on the duct wall is equal to the weight of the object, N = mg = 10kg × 9.8m / s. ² =98N.

[0086] Since the thrust is independent of displacement and only affects the push rod stroke and work done, the thrust of the first electric push rod 22 and the second electric push rod 23 only needs to overcome the rolling friction. When moving at a constant speed, the thrust = rolling friction, and the formula is: F = μr × N. Theoretically, the friction of the inner wall of the 3PE anti-corrosion steel pipe is about μr = 0.015, and the theoretical thrust is: F = 0.015 × 98 = 1.47 N. However, the movement inside the pipe is not an ideal smooth working condition, and there are also water stains, etc. The thrust can be appropriately increased. Then, the first electric push rod 22 and the second electric push rod 23 with appropriate thrust can be selected. By alternately running the first electric push rod 22 and the second electric push rod 23, the drying component can be driven to move back and forth.
