Description

Technical Field

[0001] This utility model relates to the technical field of water-saving pipe production equipment, specifically a cooling device for water-saving pipe production. Background Technology

[0002] During the production of water-saving pipes, the newly extruded pipes are at a high temperature and require cooling to ensure dimensional stability and mechanical properties, facilitating subsequent cutting, handling, and storage. Cooling devices are needed for this process. Open cooling is a commonly used method in pipe production; however, the cooling water is often reused directly. Repeated reuse of this water leads to the accumulation of impurities, causing these impurities to adhere to the pipe surface during cooling, affecting product quality. Furthermore, a large amount of moisture remains on the cooled pipe surface; if not treated promptly, this can affect subsequent processing steps and may even cause rust or corrosion, reducing pipe quality. Therefore, we propose a cooling device for water-saving pipe production to address these issues. Utility Model Content

A multi-nozzle nozzle is fixedly connected to the inner top wall of the cooling box. A water pump is installed inside the water storage tank, and a water delivery pipe is fixedly connected to the outlet of the water pump. The bottom end of the water delivery pipe passes through the water storage tank, the base, and the cooling box in sequence, and is fixedly connected to the outer surface of the multi-nozzle nozzle. Two air ducts are fixedly connected to the inner wall of the drying box. Hot air blowers are fixedly connected to the upper and lower surfaces of the drying box. A guide pipe is fixedly connected to the outlet of each hot air blower. The end of each guide pipe away from the hot air blower passes through the drying box and is fixedly connected to the right end of the air duct.

[0010] This utility model has the following advantages compared with the prior art:

[0011] This invention establishes a water circulation system comprising a sedimentation tank, a filter tank, a water storage tank, and supporting pipelines. After cooling water is used in the cooling tank, it sequentially enters the sedimentation tank through the drain pipe for initial sedimentation, then flows through the water guide pipe into the filter tank. There, it undergoes three stages of filtration—coarse filter, fine filter, and activated carbon filter—to remove impurities and odors. Finally, the water flows back to the water storage tank for reuse, avoiding direct reuse of the cooling water. The cooled pipes then enter a drying chamber, where hot air generated by a hot air blower is delivered to the air duct through a guide pipe. The air duct evenly distributes the hot air onto the pipe surface, quickly evaporating residual moisture and preventing rust and corrosion. This also prevents moisture from affecting subsequent cutting, handling, and storage processes, ensuring the dimensional stability and mechanical properties of the pipes and improving product quality.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 5 The cooling device for water-saving pipe production shown includes a base 1. A cooling box 2 and a drying box 3 are fixedly connected to the upper surface of the base 1. Two sets of support legs 15 are fixedly connected to the bottom surface of the base 1. Each set of support legs 15 has an anti-slip ring 16 fixedly connected to its outer surface. The two sets of support legs 15 provide stable support for the entire device, raise the distance between the base 1 and the ground, and prevent the bottom surface of the base 1 from directly contacting the ground and getting damp and corroded. The anti-slip ring 16 increases the friction between the support legs 15 and the ground, and prevents the equipment from shifting due to vibration during operation.

[0020] The bottom surface of the base 1 is fixedly connected to a sedimentation tank 4, a filter tank 5, and a water storage tank 6 in sequence. Water guide pipes 8 are fixedly connected to both sides of the filter tank 5. The ends of the two water guide pipes 8 that are far apart from each other are fixedly connected to the sides of the water storage tank 6 and the sedimentation tank 4 that are close to each other. A drain pipe 7 is fixedly connected to one side of the cooling tank 2. The bottom end of the drain pipe 7 passes through the base 1 and is fixedly connected to the upper surface of the sedimentation tank 4. The left and right sides of the cooling tank 2 are provided with first material inlets 17. Each first material inlet 17 is provided with a first sealing curtain 18. The first material inlet 17 provides a channel for the pipe to enter and exit the cooling tank 2. The pipe can enter the cooling tank 2 for cooling from one side of the first material inlet 17. After cooling, it is sent out from the other side of the first material inlet 17. The first sealing curtain 18 can be lifted by the pipe when the pipe enters and exits, which does not affect the pipe transportation and can prevent external dust and impurities from entering the cooling tank 2 and contaminating the cooling water or the surface of the pipe.

[0021] The lower part of the cooling tank 2 is rotatably connected to three conveying rollers 19 via bearings. The three conveying rollers 19 are spaced apart inside the cooling tank 2. The three conveying rollers 19 can be driven by an external power source, such as a motor, to move the pipe at a uniform speed. The ends of the three conveying rollers 19 are connected by a sprocket and chain drive. The end of one of the conveying rollers 19 is connected to the output end of the motor, so that the pipe maintains a stable conveying speed inside the cooling tank 2, ensuring that all parts of the pipe can fully contact the cooling water and achieve uniform cooling. A one-way valve 20 is fixedly connected to one side of the water storage tank 6. The one-way valve 20 allows fresh water from the outside to flow into the water storage tank 6 in one direction and prevents the filtered cooling water in the water storage tank 6 from flowing back out, ensuring the sealing of the water circulation system and the stability of the water volume.

[0022] The inner top wall of the cooling tank 2 is fixedly connected to a multi-nozzle nozzle 21. The water tank 6 is equipped with a water pump 22. The outlet of the water pump 22 is fixedly connected to a water delivery pipe 23. The bottom end of the water delivery pipe 23 passes through the water tank 6, the base 1 and the cooling tank 2 in sequence and is fixedly connected to the outer surface of the multi-nozzle nozzle 21. The water pump 22 provides power for the circulation of cooling water and can draw the filtered cooling water in the water tank 6 to the water delivery pipe 23. The water delivery pipe 23 serves as a channel to deliver the cooling water to the multi-nozzle nozzle 21 in the cooling tank 2. The multi-nozzle nozzle 21 has multiple nozzles, which can evenly spray the cooling water onto the surface of the pipe moving on the conveying roller 19. Compared with a single nozzle, it can expand the cooling coverage area and make the cooling speed of each area of ​​the pipe surface uniform.

[0023] The inner wall of the filter box 5 is fixedly connected with a coarse filter screen 9, a fine filter screen 10, and an activated carbon filter screen 11. A cleaning groove 24 is provided on one side of the sedimentation box 4. A sealing plate 25 is installed inside the cleaning groove 24. The cooling water will accumulate silt, pipe debris, and other impurities in the sedimentation box 4. By periodically opening the sealing plate 25, the impurities settled in the box can be directly cleaned through the cleaning groove 24 to prevent the accumulation of impurities from clogging the water pipe 8 and to ensure that the water circulation channel is unobstructed.

[0024] Two air ducts 12 are fixedly connected to the inner wall of the drying chamber 3. Hot air blowers 13 are fixedly connected to the upper and lower surfaces of the drying chamber 3. Each hot air blower 13 has a guide pipe 14 fixedly connected to its outlet end. The end of each guide pipe 14 away from the hot air blower 13 passes through the drying chamber 3 and is fixedly connected to the right end of the air duct 12. Second material inlets 26 are provided on both the left and right sides of the drying chamber 3. A second sealing curtain 27 is provided inside each second material inlet 26. The second material inlet 26 provides a channel for the cooled pipes to enter and exit the drying chamber 3. After the pipes are sent out from the cooling chamber 2, they can directly enter the drying chamber 3 for drying from one side of the second material inlet 26. After drying, they are sent out from the other side of the second material inlet 26. The second sealing curtain 27 can be lifted when the pipes enter and exit or blown slightly when the hot air blower 13 is running. The second sealing curtain 27 maintains a stable drying temperature environment inside the chamber, improves drying efficiency, and prevents external dust from entering the drying chamber 3 and contaminating the surface of the pipes.

[0025] A support block 28 is fixedly connected to the outer surface of the water pump 22. The bottom surface of the support block 28 is fixedly connected to the inner bottom wall of the water storage tank 6. The support block 28 fixes the water pump 22 above the inner bottom wall of the water storage tank 6, preventing the water pump 22 from directly contacting the cooling water or impurities at the bottom of the water storage tank 6, preventing the water pump 22 from being damaged by moisture due to long-term immersion, and reducing the vibration and friction between the water pump 22 and the bottom of the tank when it is working.

[0026] The working process of this embodiment is as follows:

[0027] In use, first connect the hot air blower 13 and water pump 22 to the power supply, open the one-way valve 20 of the water storage tank 6, and inject sufficient cooling water into the water storage tank 6. After filling, close the one-way valve 20, and then start the water pump 22. The water pump 22 runs stably under the fixing action of the support block 28, and delivers the cooling water in the water storage tank 6 to the multi-nozzle nozzle 21 on the top wall of the cooling box 2 through the water delivery pipe 23. The multi-nozzle nozzle 21 begins to spray cooling water into the cooling box 2 until a stable cooling environment is formed inside the cooling box 2. The newly extruded high-temperature water-saving pipe is then inserted from the first nozzle on the left side of the cooling box 2. The material is fed in through inlet 17, and the first sealing curtain 18 inside the first inlet 17 is lifted, without affecting the entry of the pipe. The pipe falls onto the three conveying rollers 19 on the inner wall of the cooling box 2. The conveying rollers 19 rotate at a uniform speed, driving the pipe to move to the right. During the movement, the cooling water sprayed by the multi-nozzle nozzle 21 evenly covers the surface of the pipe, absorbing the heat of the pipe and achieving cooling. The used cooling water carries a small amount of pipe debris and impurities, and flows into the sedimentation tank 4 on the bottom surface of the base 1 through the drain pipe 7 on one side of the cooling box 2. Preliminary sedimentation occurs in the sedimentation tank 4, where impurities are deposited at the bottom of the tank, and the upper layer of sedimentation tank 4 is clear. Cooling water flows into filter box 5 through water pipe 8, and sequentially passes through coarse filter screen 9 on the inner wall of filter box 5 to filter large particles of impurities, fine filter screen 10 to filter fine debris, and activated carbon filter screen 11 to adsorb odors and tiny impurities, completing three-stage filtration. The filtered clean cooling water flows back to water storage tank 6 through another water pipe 8, realizing water resource recycling. The sealing plate 25 of sedimentation tank 4 is opened periodically, and the impurities deposited in the tank are cleaned through cleaning tank 24. If the water volume in water storage tank 6 decreases due to loss, the one-way valve 20 can be opened to add new water to maintain the stability of the water circulation system. The pipe is fed out from the first inlet 17 on the right side of the cooling box 2 and directly enters the second inlet 26 on the left side of the drying box 3. The second sealing curtain 27 inside the second inlet 26 is lifted up, and the hot air blowers 13 on the upper and lower surfaces of the drying box 3 are started. The hot air generated by the hot air blowers 13 is delivered to the two air ducts 12 on the inner wall of the drying box 3 through the guide pipe 14. The two air ducts 12 blow hot air evenly from above and below the pipe, respectively, and use convection to quickly evaporate the residual moisture on the surface of the pipe. After drying, the pipe is sent out from the second inlet 26 on the right side of the drying box 3 and enters the subsequent cutting, handling and other processes.
