Description

Technical Field

[0001] This utility model relates to the technical field of pipe processing equipment, and specifically to a pipe cooling system. Background Technology

[0002] In the production of metal components such as pipes, raw metal materials are typically rolled into the desired shape, and then welded to seal the gaps after rolling, forming a closed pipe. After rolling and welding, the surface temperature of the pipe usually rises. To facilitate subsequent processing, the pipe is typically cooled after welding to quickly lower its surface temperature to room temperature for further processing. Cooling water is usually used for this process. To minimize water consumption and avoid waste, the used cooling water is usually recycled and reused.

[0003] For example, patent document CN 218380134U discloses a steel pipe cooling device, which includes a cooling pool, an upper cooling pipe on the cooling pool, several first drainage holes on the side of the upper cooling pipe near the cooling pool, an inlet pipe on the upper cooling pipe, an outlet pipe at the bottom of the cooling pool, and a heat dissipation mechanism for dissipating heat from the water flow outside the cooling pool. The inlet pipe is connected to the bottom of the heat dissipation mechanism, and the outlet pipe extends to the top of the heat dissipation mechanism.

[0004] While the above technical solution can reduce water waste during the cooling process, it directly connects the cooling pool to the heat dissipation mechanism when recycling cooling water. During the cooling water circulation, the cooled water, after being heated in the cooling pool, is sent to the heat dissipation mechanism for heat dissipation before being sent back to the cooling pool to cool the pipes. Furthermore, to ensure a sufficient supply of cooling water to the cooling pool, redundant cooling water is usually designed into the cooling device. This leads to a situation where, during the heat dissipation process, the already cooled cooling water in the heat dissipation mechanism mixes with the newly input high-temperature cooling water, causing the temperature of the cooling water output to the cooling pool to rise. Consequently, the temperature of the cooling water cannot meet the cooling requirements of the pipes during the cooling process, resulting in a reduction in the heat absorption capacity of the cooling water and the cooling effect on the pipes. Utility Model Content

[0005] The present invention aims to provide a pipe cooling system to solve the technical problem in the prior art where the cooling water that has already dissipated heat in the heat dissipation mechanism mixes with the newly input high-temperature cooling water, resulting in the cooling water temperature failing to meet the cooling requirements of the pipe during the cooling process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pipe cooling system, comprising a cooling tank, a water storage tank, and a cooling tower; an inlet pipe is provided between the cooling tank and the water storage tank, the inlet pipe being used to transport cooling water from the water storage tank to the cooling tank, and the cooling tank being used to cool the pipe with the cooling water; a return pipe is provided between the cooling tank and the cooling tower, the return pipe being used to transport the cooling water in the cooling tank to the cooling tower; the cooling tower being used to cool the cooling water in the cooling tank; and a delivery pipe is provided between the cooling tower and the water storage tank, the delivery pipe being used to deliver the cooled water from the cooling tower to the water storage tank for storage.

[0007] The principle and advantages of this scheme are as follows: When cooling the pipes, the pipes are inserted into a cooling tank, and cooling water from the storage tank is transported to the cooling tank through the inlet pipe to cool the pipes. During the cooling process, the cooling water that absorbs heat from the pipes and heats up is transported to the cooling tower through the return pipe for further cooling. The cooled water is then transported to the storage tank for storage, thus achieving the recycling of cooling water.

[0008] Compared to existing technologies, this solution separates the cooling water in the cooling tank from the cooling tower during pipe cooling. This separation prevents the cooled water from being reheated by newly added cooling water, thus avoiding an overall temperature increase that could affect the cooling effect on the pipe. Furthermore, the storage tank ensures a sufficient reserve of cooling water in the system, guaranteeing a steady supply during pipe cooling and preventing delays in cooling process.

[0009] Preferably, as an improvement, a spray pipe is provided at one end of the water inlet pipe in the cooling tank. The spray pipe has multiple openings and is used to spray cooling water into the cooling tank. This ensures that the cooling water can be evenly delivered to all areas of the cooling tank during the cooling process, guaranteeing the temperature uniformity within the cooling tank.

[0010] Preferably, as an improvement, the cooling tower includes a tower body, and a riser pipe is provided inside the tower body. One end of the riser pipe passes through the bottom of the tower body, and the other end extends towards the top of the tower body along the height direction. The end of the riser pipe located at the bottom of the tower body is connected to the return water pipe.

[0011] Preferably, as an improvement, the tower body is provided with a filling layer, which is distributed circumferentially around the riser pipe. Specifically, the riser pipe is located on the central axis of the tower body, and the filling layer surrounds the circumference of the riser pipe.

[0012] Preferably, as an improvement, the filling layer has multiple sub-layers, which are stacked and distributed along the radial direction of the tower body. This allows the cooling water, after being transported to the top of the tower through the riser pipe, to slowly fall along the gaps between the sub-layers, ensuring that the cooling water can remain in the tower body for a sufficient period of time and guaranteeing the cooling effect.

[0013] Preferably, as an improvement, the filler layer is provided with multiple corrugated grooves, which are evenly distributed along the circumferential direction of the tower body. This increases the surface area of ​​the filler layer during the dripping process of the cooling water, ensuring that the cooling water can cool more thoroughly.

[0014] Preferably, as an improvement, the top of the tower body is also provided with an air outlet, and a cooling fan is installed inside the air outlet; an air inlet is provided on the side wall near the bottom of the tower body, and the air inlets are distributed around the circumference of the tower body. By installing a cooling fan at the top of the tower body, the air velocity inside the tower body is increased, the efficiency of heat dissipation inside the tower body is increased, and the cooling effect of the cooling water is improved.

[0016] Figure 2 This is a schematic diagram of the cooling tower structure in an embodiment of this utility model. Detailed Implementation

[0017] The following detailed description illustrates the specific implementation method:

[0018] The reference numerals in the accompanying drawings include: cooling tank 1, cooling cavity 101, outlet 102, spray pipe 103, water storage tank 2, cooling tower 3, tower body 301, riser pipe 302, filling layer 303, water collection tray 304, air outlet 305, cooling fan 306, baffle plate 307, air inlet 308, water inlet pipe 4, water return pipe 5, and water supply pipe 6.

[0019] As attached Figure 1 As shown, a pipe cooling system includes a cooling tank 1, a water storage tank 2, and a cooling tower 3. Cooling water is stored in the water storage tank 2. The cooling tank 1 is used to draw cooling water from the water storage tank 2 to cool the pipe. The cooling tower 3 is used to cool the cooling water in the cooling tank 1 and then transport it to the water storage tank 2 for storage.

[0020] A cooling chamber 101 is formed inside the cooling tank 1, and cooling water is stored in the cooling chamber 101. An inlet and an outlet 102 are respectively formed at both ends of the cooling tank 1. When cooling the pipe, the pipe passes through the cooling chamber 101 in the cooling tank 1 through the inlet and outlet 102. An opening communicating with the cooling chamber 101 is formed at the top of the cooling tank 1. The extension direction of the opening is the same as the extension direction of the cooling chamber 101. A spray pipe 103 for spraying cooling water into the cooling chamber 101 is provided above the opening. The extension direction of the spray pipe 103 is the same as the extension direction of the opening. The spray pipe 103 is fixedly connected to the cooling tank 1 by a bracket.

[0021] A water inlet pipe 4 is provided between the spray pipe 103 and the water storage tank 2. One end of the water inlet pipe 4 is threaded to the middle of the spray pipe 103, and the other end of the water inlet pipe 4 is connected to the water storage tank 2 via a water pump. The water inlet pipe 4 is used to transport cooling water from the water storage tank 2 to the spray pipe 103. Multiple openings are provided on the side of the spray pipe 103 near the cooling tank 1, and these openings are evenly distributed along the length of the spray pipe 103. Cooling water in the spray pipe 103 is sprayed into the cooling tank 1 through these openings. This ensures that when cooling the pipe, cooling water is drawn from the water storage tank 2 to cool the pipe, providing a sufficient supply of cooling water to guarantee uninterrupted operation of the pipe cooling process.

[0022] A return water pipe 5 is installed between the cooling tank 1 and the cooling tower 3. One end of the return water pipe 5 is connected to the bottom of the cooling tank 1 and communicates with the cavity of the cooling tank 1, while the other end is connected to the inlet of the cooling tower 3. A water pump is also installed on the return water pipe 5 to collect the cooling water in the cooling tank 1 and transport it to the cooling tower 3 for cooling. This ensures that the heated cooling water in the cooling tank 1 can be discharged in a timely manner by the action of the return water pipe 5, preventing the temperature of the cooling water in the cooling tank 1 from becoming too high and affecting the cooling effect of the pipe.

[0023] As attached Figure 2 As shown, the cooling tower 3 includes a tower body 301, and a riser pipe 302 is provided inside the tower body. One end of the riser pipe 302 passes through the bottom of the tower body 301, and the other end extends towards the top of the tower body 301 along the height direction. The end of the riser pipe 302 at the bottom of the tower body 301 serves as the input port of the tower body 301. A filling layer 303 is also provided inside the tower body 301. The filling layer 303 is distributed circumferentially around the riser pipe 302. Specifically, the riser pipe 302 is located on the central axis of the tower body 301, and the filling layer 303 surrounds the circumference of the riser pipe 302.

[0024] The filling layer 303 has multiple sub-layers, which are stacked and distributed radially within the tower body 301. Gaps are provided between the sub-layers to allow cooling water to pass through. The sub-layers can be made of materials such as metal, plastic, or fiberglass. Preferably, in this embodiment, the sub-layers are annular structures made of fiberglass, with multiple sub-layers sequentially nested around the outside of the riser pipe 302. This allows the cooling water, after being transported to the top of the tower body 301 through the riser pipe 302, to slowly fall along the gaps between the sub-layers, ensuring that the cooling water can remain within the tower body 301 for a sufficient period of time, thus guaranteeing the cooling effect.

[0025] Multiple corrugated grooves are provided on the packing sublayer, and these grooves are evenly distributed along the circumferential direction of the tower body 301. In other words, the packing sublayer is a corrugated plate. This increases the surface area of ​​the packing sublayer during the dripping process of the cooling water, ensuring more thorough cooling.

[0026] A water collection tray 304 is located near the bottom of the cooling tower 301. The water collection tray 304 is used to collect the cooling water falling from the filling layer 303. A water outlet is provided on the water collection tray 304 to discharge the cooling water in the water collection tray 304. A water supply pipe 6 is provided between the water outlet and the water storage tank 2 to transport the cooled water in the cooling tower 301 to the water storage tank 2 for storage. This ensures that the cooled water can be collected and discharged under the action of the water collection tray 304, preventing the cooling water from stagnating in the cooling tower 3.

[0027] An air outlet 305 is provided at the top of the tower body 301. A cooling fan 306 is rotatably connected to the air outlet 305 via a rotating shaft. The shaft of the cooling fan 306 is connected to the output shaft of a motor. A baffle plate 307 is provided at one end of the air outlet 305 near the filling layer 303. The baffle plate 307 can be a corrugated plate or similar structure. The baffle plate 307 is used to separate moisture from the air drawn in by the cooling fan 306. The specific structure of the baffle plate 307 is existing technology and will not be described in detail here. By installing a cooling fan 306 at the top of the tower body 301, the airflow velocity inside the tower body 301 is increased, the efficiency of heat dissipation inside the tower body 301 is increased, and the cooling effect of the cooling water is improved.

[0028] An air inlet 308 is provided on the side wall near the bottom of the tower body 301. The air inlet 308 connects the inner wall and the outer wall of the tower body 301 and is distributed circumferentially around the tower body 301. A protective net is covered over the air inlet 308 to prevent foreign objects from entering the tower body 301. This allows air to enter from the bottom of the tower body 301 during the cooling process, ensuring that the air at the bottom of the tower body 301 absorbs heat from the cooling water, improving the cooling effect of the cooling water. At the same time, it balances the air pressure during the cooling process of the tower body 301, preventing negative pressure from occurring inside the tower body 301 and affecting the cooling effect of the cooling water.

[0029] The specific implementation process is as follows:

[0030] When cooling the pipes, the pipes are passed through the cooling chamber 101 in the cooling tank 1, and cooling water from the water storage tank 2 is transported to the cooling chamber 101 through the water inlet pipe 4 to cool the pipes. During the cooling process, the cooling water that absorbs heat from the pipes and heats up is transported to the cooling tower 3 through the return water pipe 5 for further cooling. The cooled water is then transported to the water storage tank 2 for storage, thus achieving the recycling of the cooling water.

[0031] Compared to existing technologies, this solution uses cooling tower 3 to cool and store the cooling water in cooling tank 1 separately during pipe cooling. This separation prevents the cooled water from being heated by newly added cooling water after cooling, thus avoiding an overall temperature increase that could affect the cooling effect on the pipe. Furthermore, the storage tank 2 ensures sufficient reserve cooling water in the cooling system, guaranteeing a adequate supply during pipe cooling and preventing delays in cooling water temperature that could disrupt the normal cooling process.

[0032] It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
