Spray cooling equipment for producing high-strength double-wall corrugated pipe

Abstract

The utility model discloses spray cooling equipment for high-strength double-wall corrugated pipe production, which relates to the technical field of double-wall corrugated pipe production and comprises two groups of supporting side plates, a cooling mechanism for cooling a corrugated pipe and a conveying mechanism for conveying the corrugated pipe. The cooling mechanism and the conveying mechanism are both arranged between the two sets of supporting side plates, and a supporting plate is fixedly connected between the supporting side plates. When the pre-cooling device is used, the airflow spray head is responsible for conveying airflow into the cooling cylinder, when the corrugated pipe passes through the air cooling section, the corrugated pipe can be cooled through the airflow, the closer to the position of the water cooling section, the more water vapor is generated by the water cooling section, and therefore the cooling effect on the corrugated pipe is more obvious, and the pre-cooling effect is achieved. The surface temperature of the corrugated pipe is slowly reduced, and the situation that the corrugated pipe is deformed and cracked due to sudden contact with cold water due to the fact that the temperature difference between the temperature of the corrugated pipe and the temperature of the cooling water is too large is avoided.

Description

Technical Field

[0001] This utility model relates to the field of double-wall corrugated pipe production technology, specifically to a spray cooling device for producing high-strength double-wall corrugated pipes. Background Art

[0002] The production of high-strength double-wall corrugated pipes involves processing specific materials into high-strength tubular products with a double-wall structure and corrugated appearance. Specifically, it involves using a specific molding process to shape polymer materials (such as high-density polyethylene, HDPE) into pipes with a double-wall structure and corrugated shape. The corrugated outer wall of these pipes allows for better pressure distribution and resistance, resulting in lightweight, high-strength, corrosion-resistant, and well-sealing properties.

[0003] The production of high-strength double-wall corrugated pipes involves steps such as high-temperature melting and extrusion molding. To ensure the quality and performance of the pipes, timely cooling is necessary after molding. This cooling process utilizes spray cooling equipment, which evenly sprays cooling water onto the pipe surface, achieving rapid and effective cooling.

[0004] The shortcomings of the existing technical solutions are as follows: Traditional cooling devices generally achieve the cooling effect of the double-walled corrugated pipe by directly spraying water onto it. The sprayed cooling water can be recycled. Initially, due to the low water temperature, when the double-walled corrugated pipe suddenly comes into contact with water with a large temperature difference from its own, the principle of thermal expansion and contraction may cause the pipe to deform or crack, thereby affecting its service life and performance. Utility Model Content

[0005] The purpose of this invention is to provide a spray cooling device for the production of high-strength double-wall corrugated pipes, in order to solve the technical problem in the prior art where, when the cooling device is started, the water temperature is initially low, and the double-wall corrugated pipes suddenly come into contact with water of a large temperature difference from their own. Due to the principle of thermal expansion and contraction, this may cause the pipes to deform and crack, thereby affecting their service life and performance.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A spray cooling device for producing high-strength double-wall corrugated pipes includes two sets of supporting side plates. The device also includes a cooling mechanism for cooling the corrugated pipes and a conveying mechanism for transporting the corrugated pipes. Both the cooling mechanism and the conveying mechanism are located between the two sets of supporting side plates. A supporting plate is fixedly connected between the supporting side plates. The cooling mechanism includes a cooling cylinder fixedly connected to the supporting plate. The interior of the cooling cylinder can be divided into three parts: an air-cooled section, a water-cooled section, and a controlled-drying section. A water-cooling component is installed on the water-cooled section, and an air-cooling component is installed on the end of the cooling cylinder near the controlled-drying section.

[0008] As a further embodiment of this utility model: the water cooling assembly includes multiple sets of annular pipes arranged around the cooling cylinder, multiple sets of cold water nozzles are fixedly connected inside the cooling cylinder, each set of annular pipes has multiple sets of annularly arranged cold water nozzles connected to each other, each set of annular pipes is fixedly connected to a connecting pipe, one end of the connecting pipe is fixedly connected to one end of the water supply pipe, and the other end of the water supply pipe is fixedly connected to a water pump.

[0009] As a further embodiment of this utility model: both ends of the cooling cylinder are fixedly connected to a lower ring plate, each set of the lower ring plates extends along the lower edge of the opening of the cooling cylinder, a water outlet is provided at the bottom of the cooling cylinder, a water tank connected to the water outlet is fixedly connected to the bottom of the cooling cylinder, and a drain pipe is fixedly connected to one side of the water tank.

[0010] As a further embodiment of this utility model: an upper ring plate is fixedly connected to one end of the cooling cylinder near the control section. The upper ring plate extends along the upper edge of the opening of the cooling cylinder. The air-cooling assembly includes annular air ducts fixedly installed on the upper ring plate and corresponding lower ring plates. Multiple sets of airflow nozzles connected to the annular air ducts are fixedly connected around the upper ring plate and corresponding lower ring plates. An air supply pipe is fixedly connected to one side of the annular air duct, and a fan is fixedly connected to the other end of the air supply pipe.

[0011] As a further embodiment of this utility model: the conveying mechanism includes a transmission belt and a motor fixedly connected to a set of support side plates. Each set of support side plates has a set of rotating wheels rotatably connected to both ends. The rotating wheels at both ends of the two sets of support side plates are symmetrically arranged. There are two sets of transmission belts. The two sets of rotating wheels on the same set of support side plates cooperate with the corresponding set of transmission belts. Multiple sets of U-shaped support plates for supporting the corrugated pipe are fixedly connected between the two sets of transmission belts. The output end of the motor is fixedly connected to a transmission shaft. The transmission shaft is coaxially fixedly connected to two corresponding sets of rotating wheels.

[0012] As a further embodiment of this utility model: a support slide rail that slides with the transmission belt is fixedly connected between the two sets of lower ring plates, and a notch that cooperates with the transmission belt is opened between the upper ring plate and the corresponding lower ring plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. In use, the airflow nozzle is responsible for delivering airflow into the cooling cylinder. When the corrugated pipe passes through the air-cooling section, it can be cooled by the airflow. The closer it is to the water-cooling section, the more water vapor is generated by the water-cooling section, and the more obvious the cooling effect on the corrugated pipe is, thus achieving the pre-cooling effect and slowly reducing its surface temperature. This avoids the corrugated pipe from deforming or cracking due to a large temperature difference between the corrugated pipe and the cooling water.

[0015] 2. When this utility model is in use, when the corrugated pipe enters the water cooling section, it can be cooled by directly spraying cooling water, which has the best cooling effect. When it enters the drying section, the airflow sprayed from the airflow nozzle can blow the water attached to the surface of the corrugated pipe away from the corrugated pipe, thereby accelerating the water drying process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a spray cooling device for producing high-strength double-wall corrugated pipes includes two sets of supporting side plates 1. The device also includes a cooling mechanism 3 for cooling the corrugated pipe 5 and a conveying mechanism 2 for conveying the corrugated pipe 5. Both the cooling mechanism 3 and the conveying mechanism 2 are located between the two sets of supporting side plates 1. A supporting plate 4 is fixedly connected between the supporting side plates 1. The cooling mechanism 3 includes a cooling cylinder 301 fixedly connected to the supporting plate 4. The cooling cylinder 301 is internally divided into three parts: an air-cooled section 316, a water-cooled section 317, and a controlled-drying section 318. A water-cooling component is installed on the water-cooled section 317, which cools the corrugated pipe 5 by spraying water. An air-cooling component is installed at the end of the cooling cylinder 301 near the controlled-drying section 318, and the air-cooling component sprays water onto the cooling cylinder. The internal airflow of section 301 ensures that air flows within the air-cooled section 316, water-cooled section 317, and drying section 318. The bellows 5 passes through these sections sequentially. In the air-cooled section 316, the airflow cools the bellows 5. The closer the bellows 5 is to the water-cooled section 317, the more water vapor is generated, resulting in a more significant cooling effect on the bellows 5 and achieving pre-cooling, thus slowly reducing its surface temperature. When the bellows 5 enters the water-cooled section 317, it is cooled by direct spraying of cooling water, which provides the best cooling effect. Upon entering the drying section 318, the air-cooling component blows the water adhering to the surface of the bellows 5 away, thereby accelerating the drying process.

[0024] In some specific implementations, to achieve water cooling of the corrugated pipe 5, the water cooling assembly includes multiple sets of annular pipes 312 arranged around the cooling cylinder 301. Multiple sets of cold water nozzles 313 are fixedly connected inside the cooling cylinder 301. Each set of annular pipes 312 has multiple sets of annularly arranged cold water nozzles 313 connected together to facilitate cooling of all areas on the surface of the corrugated pipe 5. Each set of annular pipes 312 is fixedly connected to a connecting pipe 311. One end of the connecting pipe 311 is fixedly connected to one end of a water supply pipe 310, and the other end of the water supply pipe 310 is fixedly connected to a water pump. The water pump is responsible for supplying water into the water supply pipe 310. After passing through the connecting pipe 311, the water sequentially enters the annular pipes 312 and is sprayed out from the cold water nozzles 313 through the annular pipes 312, thus cooling the corrugated pipe 5.

[0025] In some specific implementations, to reduce the environmental impact of the coolant, lower ring plates 303 are fixedly connected to both ends of the cooling cylinder 301. Each set of lower ring plates 303 extends along the lower edge of the opening of the cooling cylinder 301, thereby blocking the coolant outlets at both ends of the cooling cylinder 301. A drain port 306 is provided at the bottom of the cooling cylinder 301, and a drain tank 314 connected to the drain port 306 is fixedly connected to the bottom of the cooling cylinder 301. A drain pipe 315 is fixedly connected to one side of the drain tank 314. Because the outlets at both ends of the cooling cylinder 301 are blocked by the lower ring plates 303, the water inside the cooling cylinder 301 cannot flow out of the cooling cylinder 301. The water accumulated inside the cooling cylinder 301 will enter the drain tank 314 and the drain pipe 315 through the drain port 306, thereby discharging the cooling water. The discharged cooling water can be reused after cooling to continue cooling the corrugated pipe 5.

[0026] In some specific embodiments, to ensure airflow inside the cooling cylinder 301, an upper annular plate 302 is fixedly connected to one end of the cooling cylinder 301 near the control section 318. The upper annular plate 302 extends along the upper edge of the opening of the cooling cylinder 301. The air-cooling assembly includes annular air ducts 307 fixedly mounted on the upper annular plate 302 and corresponding lower annular plates 303. Multiple sets of airflow nozzles 309 connected to the annular air ducts 307 are fixedly connected around the upper annular plate 302 and the corresponding lower annular plate 303. An air supply pipe 308 is fixedly connected to one side of the annular air duct 307, and a fan is fixedly connected to the other end of the air supply pipe 308. The fan is responsible for supplying airflow to the air supply pipe 308. After passing through the annular air duct 307, the airflow is ejected from the airflow nozzles 309, thereby generating airflow inside the cooling cylinder 301.

[0027] In some specific implementations, in order to transport the corrugated pipe 5, the conveying mechanism 2 includes a transmission belt 203 and a motor 201 fixedly connected to a set of support side plates 1. Each set of support side plates 1 has a set of rotating wheels 202 rotatably connected to both ends. The rotating wheels 202 at both ends of the two sets of support side plates 1 are symmetrically arranged. There are two sets of transmission belts 203. The two sets of rotating wheels 202 on the same set of support side plates 1 cooperate with the corresponding set of transmission belts 203. The rotating wheels 202 and the transmission belts 203 can achieve a transmission effect. Multiple sets of U-shaped support plates 204 for supporting the corrugated pipe 5 are fixedly connected between the two sets of transmission belts 203. The output end of the motor 201 is fixedly connected to a transmission shaft. The transmission shaft is coaxially fixedly connected to two corresponding sets of rotating wheels 202. When transporting the corrugated pipe 5, the motor 201 drives two sets of cooperating rotating wheels 202 to rotate. These two sets of rotating wheels 202 drive two sets of transmission belts 203 to move. The two sets of transmission belts 203 drive another two sets of rotating wheels 202 to rotate. At the same time, they drive multiple sets of U-shaped pallets 204 set on the transmission belts 203 to move. The U-shaped pallets 204 support the corrugated pipe 5 and can also drive the corrugated pipe 5 to move towards the output end of the cooling cylinder 301, thus realizing the transport of the corrugated pipe 5.

[0028] In some specific implementations, in order to ensure the stability of the corrugated pipe 5 during transportation, a support slide rail 304 that slides with the transmission belt 203 is fixedly connected between the two sets of lower ring plates 303. During the movement of the corrugated pipe 5 driven by the transmission belt 203, the support slide rail 304 is responsible for supporting the transmission belt 203 to ensure stability during transportation. A notch 305 that cooperates with the transmission belt 203 is opened between the upper ring plate 302 and the corresponding lower ring plate 303, thereby facilitating the movement of the transmission belt 203.

[0029] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be explained in conjunction with specific application scenarios:

[0030] When cooling the corrugated pipe 5, the motor 201 can be started. The motor 201 drives two sets of rotating wheels 202 that are connected to each other to rotate. These two sets of rotating wheels 202 will drive two sets of transmission belts 203 to move. The two sets of transmission belts 203 drive another two sets of rotating wheels 202 to rotate. At the same time, they drive multiple sets of U-shaped pallets 204 set on the transmission belts 203 to move. The U-shaped pallets 204 support the corrugated pipe 5 and can also drive the corrugated pipe 5 to pass through the air-cooling section 316, the water-cooling section 317 and the controlled drying section 318 in sequence to realize the transportation of the corrugated pipe 5.

[0031] The fan is responsible for supplying airflow to the air supply pipe 308. After passing through the annular air duct 307, the airflow is ejected from the airflow nozzle 309, thereby generating airflow inside the cooling cylinder 301 to air-cool the corrugated pipe 5 entering the air-cooling section 316, achieving a pre-cooling effect. The water pump is responsible for supplying water to the water supply pipe 310. After passing through the connecting pipe 311, the water enters the annular pipe 312 in sequence, and is ejected from the cold water nozzle 313 through the annular pipe 312 to cool the corrugated pipe 5 entering the water-cooling section 317. When the corrugated pipe 5 enters the drying section 318, the airflow inside the cooling cylinder 301 will blow the water adhering to the surface of the corrugated pipe 5 away from the corrugated pipe 5, thereby accelerating the water drying process.

[0032] Because the outlets at both ends of the cooling cylinder 301 are blocked by the lower ring plate 303, the water inside the cooling cylinder 301 cannot flow out of the cooling cylinder 301 from both ends. The water accumulated inside the cooling cylinder 301 will enter the water tank 314 and the drain pipe 315 through the drain outlet 306 in sequence, thereby realizing the discharge of cooling water. The discharged cooling water can be reused after cooling to continue cooling the corrugated pipe 5.

[0033] Airflow nozzle 309 is responsible for delivering airflow into the cooling cylinder 301, ensuring airflow within the air-cooled section 316, water-cooled section 317, and drying control section 318. The bellows 5 passes through these sections sequentially. In the air-cooled section 316, the airflow cools the bellows 5. The closer the bellows 5 is to the water-cooled section 317, the more water vapor it generates, resulting in a more significant cooling effect and pre-cooling. This allows the surface temperature to decrease slowly, preventing deformation or cracking due to a large temperature difference between the bellows 5 and the cooling water. When the bellows 5 enters the water-cooled section 317, it is cooled by direct spraying of cooling water, which provides the best cooling effect. Upon entering the drying control section 318, the air-cooling component blows the water adhering to the surface of the bellows 5 away, accelerating the drying process.
