Description

Technical Field

[0001] This utility model relates to the field of polyethylene solid wall drainage pipe technology, and in particular to a cooling device for polyethylene solid wall drainage pipe. Background Technology

[0002] Solid-wall polyethylene (HDPE) drainage pipes are continuous, non-porous, and uniformly thick circular plastic drainage pipes made primarily from high-density polyethylene (HDPE) through extrusion molding. They feature a smooth inner wall, low fluid resistance, excellent corrosion resistance, chemical resistance, and flexibility, allowing them to withstand uneven foundation settlement without cracking. The pipes are typically connected using socket-type elastic sealing rings or hot-melt butt welding, ensuring reliable sealing and excellent leak-proof performance. They are suitable for gravity-flow rainwater and sewage discharge systems in residential communities, municipal engineering projects, and agricultural irrigation. Compared to traditional concrete or cast iron pipes, solid-wall polyethylene drainage pipes are lighter, easier to install, and have a lifespan of over 50 years. Furthermore, their production and use are environmentally friendly and energy-saving, making them an important material for modern green drainage network construction.

[0003] Currently, the production of polyethylene solid-wall drainage pipes generally adopts traditional cooling methods such as open cooling water tanks or spray cooling boxes. These methods have obvious shortcomings in practical applications: open water tanks rely on the natural convection of water, resulting in low and uneven cooling intensity, which can easily lead to defects such as bending, excessive ellipticity, or even surface wrinkles in the pipes due to excessive temperature differences between the inner and outer walls.

[0004] Therefore, a cooling device for polyethylene solid-walled drainage pipes needs to be designed to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of the current production of polyethylene solid wall drainage pipes, which mostly uses open water tanks or spray cooling boxes, resulting in low and uneven cooling intensity and easy bending, excessive ellipticity, or surface wrinkling of the pipes due to internal and external temperature differences, this utility model provides a cooling device for polyethylene solid wall drainage pipes.

[0006] The technical solution of this utility model is as follows: a cooling device for polyethylene solid-walled drainage pipes, comprising a cooling frame, partitions, a cooling water tank, an inlet pipe, a water delivery pipe, a water pump, a branch pipe, an arc-shaped pipe, an atomizing nozzle, a controller, a swing assembly, and a drainage assembly. The cooling frame has circular openings on both sides, one side being the inlet and the other side being the outlet. Two partitions are fixedly connected in a linear array inside the cooling frame, dividing the interior into three cooling chambers. A cooling water tank is fixedly connected to the right side of the cooling frame, and an inlet is fixedly connected and connected to the rear of the cooling water tank. The cooling water tank has a water supply pipe fixedly installed inside. The bottom of the water supply pipe is fixedly connected to and connected to a water pump. The top of the water supply pipe extends out of the cooling water tank and is fixedly connected to a branch pipe. Each of the three cooling chambers has two arc-shaped pipes rotatably connected inside. Each arc-shaped pipe has multiple atomizing nozzles fixedly connected in a linear array inside. The rear of the branch pipe has six branch pipes. Each branch pipe passes through the cooling frame and is rotatably connected to and connected to the front of the corresponding arc-shaped pipe. The rear of the cooling frame is fixedly connected to a controller. The water pump is electrically connected to the controller. The front of the cooling frame has a swing assembly, and the bottom of the cooling frame has a drainage assembly.

[0007] In one embodiment, two atomizing nozzles are staggered and symmetrically distributed within each cooling chamber.

[0008] In one embodiment, the swing assembly includes a support rod, a motor, a cam, a fixed housing, a gear, a double rack, and a guide rod. The support rod is fixedly connected to the front of the cooling frame, and the motor is fixedly connected to the middle of the support rod. The motor is electrically connected to the controller, and the output shaft of the motor is fixedly connected to the cam. Three fixed housings are fixedly connected to the front of the cooling frame in a linear array. A gear is fixedly connected to the front of each arc-shaped tube. A double rack is slidably connected inside each fixed housing. Multiple tooth blocks are provided on both sides of each double rack. Each double rack meshes with the gear through the corresponding multiple tooth blocks. A guide rod is fixedly connected between the bottoms of the three double racks. A cylinder is provided on the upper part of the cam, and a slot is opened on the guide rod. The cylinder slides inside the slot.

[0009] In one embodiment, each gear is located inside a corresponding fixed housing.

[0010] In one embodiment, the drainage assembly includes a water outlet pipe and a valve. The water outlet pipe is fixedly fitted at the bottom of the cooling frame, and three vertical pipes are provided at the top of the water outlet pipe. Each of the three vertical pipes is connected to a corresponding cooling chamber. The right side of the water outlet pipe is fixedly connected to and connected to a valve.

[0011] In one embodiment, a wiping ring is also included, with the wiping ring sleeved inside the outlet.

[0012] The beneficial effects of this utility model are: 1. This utility model delivers cooling water to six arc-shaped pipes via a water pump, a distribution pipe, and a branch pipe. The atomizing nozzles on these pipes form a fine water mist, which cools the pipes as they pass through three cooling chambers in stages. At the same time, the oscillating assembly drives all the arc-shaped pipes and nozzles to oscillate back and forth. Combined with the staggered and symmetrical distribution layout, this achieves dynamic and uniform coverage of the cooling medium on the circumferential surface of the pipes, significantly reducing the risk of defects such as bending, excessive ellipticity, and surface wrinkles caused by excessive temperature differences between the inner and outer walls.

[0013] 2. This utility model uses a motor to drive a cam to rotate. The cam's cylindrical shape slides within the slot of the guide rod, converting the rotational motion into the reciprocating motion of the guide rod. The double rack connected to the guide rod slides within the fixed housing. Through the meshing of the toothed block and the gear, the linear motion is converted into the reciprocating rotation of the gear and the arc-shaped tube. The oscillating mechanism allows the atomized water mist to continuously scan the entire outer surface of the pipe, completely eliminating the cooling dead zones present in traditional fixed spray systems. This provides a reliable guarantee for obtaining pipe products that are round and dimensionally stable.

[0014] 3. This utility model can collect and discharge the unevaporated cooling water accumulated at the bottom of the cooling chamber in a timely manner through the water outlet pipe and its riser. Operators can easily control the drainage process through the valve to prevent water accumulation from causing adverse effects on the cooling environment or equipment. In addition, the wiping ring installed at the outlet pipe can effectively scrape off the water droplets attached to the surface of the pipe when it is removed, keeping the pipe relatively dry and reducing interference with subsequent processes.

Detailed Implementation

[0022] A cooling device for polyethylene solid-walled drain pipes, such as Figures 1-6 As shown, it includes a cooling frame 1, partitions 2, a cooling water tank 3, an inlet pipe 4, a water delivery pipe 5, a water pump 6, a diversion pipe 7, an arc-shaped pipe 8, an atomizing nozzle 9, a controller 10, a support rod 13, a motor 14, a cam 15, a fixed shell 16, a gear 17, a double rack 18, a guide rod 19, an outlet pipe 11, a valve 12, and a wiping ring 20. The cooling frame 1 has circular openings on both the left and right sides; the left opening is the inlet, and the right opening is the outlet. Two partitions 2 are welded in a linear array inside the cooling frame 1, dividing the interior of the cooling frame 1 into three cooling chambers. The right side of the cooling frame 1... A cooling water tank 3 is installed on the lower side with screws. A water inlet pipe 4 is fixedly connected to and connected to the upper rear side of the cooling water tank 3. A water delivery pipe 5 is fixedly fitted inside the cooling water tank 3. A water pump 6 is fixedly connected to the bottom end of the water delivery pipe 5. A branch pipe 7 is welded to the top end of the water delivery pipe 5, extending out of the cooling water tank 3. Two arc-shaped pipes 8 are rotatably connected inside each of the three cooling chambers. Multiple atomizing nozzles 9 are fixedly connected in a linear array inside each arc-shaped pipe 8. The two atomizing nozzles 9 in each cooling chamber are symmetrically distributed, alternating vertically. Six branch pipes are provided behind the branch pipe 7, each branch pipe penetrating the cooling frame 1 and... The front end of the corresponding arc-shaped tube 8 is rotatably connected and communicated. A controller 10 is installed on the rear right side of the cooling frame 1 by screws. The water pump 6 is electrically connected to the controller 10. A support rod 13 is welded to the front of the cooling frame 1. A motor 14 is installed in the middle of the support rod 13 by screws. The motor 14 is electrically connected to the controller 10. A cam 15 is fixedly connected to the output shaft of the motor 14. Three fixed shells 16 are fixedly connected in a linear array on the front side of the cooling frame 1. A gear 17 is welded to the outer side of the front end of each arc-shaped tube 8. Each gear 17 is located inside the corresponding fixed shell 16. Each fixed shell 16 has a sliding mechanism inside. A double rack 18 is connected, and each double rack 18 has multiple tooth blocks on its left and right sides. Each double rack 18 meshes with a gear 17 through the corresponding multiple tooth blocks. A guide rod 19 is fixedly connected between the bottom sides of the three double racks 18. A cylinder is provided on the upper rear side of the cam 15. A slot is opened on the guide rod 19, and the cylinder slides inside the slot. A water outlet pipe 11 is fixedly sleeved on the bottom side of the cooling frame 1. Three vertical pipes are provided on the top side of the water outlet pipe 11. The three vertical pipes are all connected to the three corresponding cooling chambers. A valve 12 is fixedly connected to the right end of the water outlet pipe 11. A wiping ring 20 is sleeved inside the outlet.

[0023] When this device is needed to cool the polyethylene solid-wall water outlet pipe 11, the water pump 6 and motor 14 are first started by the controller 10. The water pump 6 starts working, pumping the cooling water in the cooling water tank 3 into the distribution pipe 7 through the water supply pipe 5. Then, the cooling water is delivered to the six arc-shaped pipes 8 in the three cooling chambers through the six branch pipes behind the distribution pipe 7. Finally, it is sprayed out by multiple atomizing nozzles 9 to form a fine and uniform water mist, which provides step-by-step and efficient spray cooling for the pipe material that enters from the inlet and passes through the three cooling chambers in sequence. At the same time, after the motor 14 starts, its output shaft drives the cam 15 to start rotating and slide inside the slot, thereby driving the guide rod 19 into the groove. The three double racks 18 slide back and forth synchronously inside the corresponding fixed shells 16, and the linear motion of the double racks 18 is converted into the reciprocating rotation of the gears 17. This motion is finally transmitted to the arc tubes 8, which drive all the arc tubes 8 and the atomizing nozzles 9 on them to swing back and forth at a certain angle around the connection point with the branch pipe. This swinging process ensures that the atomized water mist can dynamically and evenly cover the entire circumferential surface of the pipe. Combined with the symmetrical layout of the arc tubes 8 in each cooling chamber, uniform cooling without dead angles is achieved, which effectively avoids the deformation and internal stress of the pipe caused by local cooling that is too fast or too slow.

[0024] During the cooling process, some of the unevaporated cooling water collects at the bottom of the cooling chamber under gravity. The accumulated water is collected through the three risers of the outlet pipe 11 and flows into the main outlet pipe 11. Operators can adjust the drainage flow or completely drain the water by controlling the opening of valve 12. To further optimize the effect, when the cooled pipe is removed from the outlet, the wiping ring 20 can effectively scrape off most of the water droplets remaining on its outer surface, keeping the pipe dry and facilitating subsequent processes. When the cooling operation is completed or needs to be paused, the water pump 6 and motor 14 are turned off sequentially via controller 10. The water pump 6 stops supplying water, and the atomizing nozzle 9 immediately stops spraying.

[0025] After motor 14 stops, cam 15 stops at a random angle, guide rod 19 and double rack 18 stop moving under gravity and transmission resistance, and gear 17 and arc tube 8 also stop at their current positions. Valve 12 on outlet pipe 11 is closed, and the entire device resets to standby mode, ready for the next startup.
