Description

Technical Field

[0001] This utility model relates to the field of pipe sizing cooling circulation, and in particular to a cooling mechanism for pipe sizing devices. Background Technology

[0002] After extrusion molding, the pipe is relatively soft and requires rapid cooling and sizing. The conventional cooling method of sizing equipment is to continuously spray circulating cooling water into the pipe. For large pipes, more cooling water is required. Often, after multiple cycles of cooling water, the cooling water in the circulation system has not been completely cooled down before entering the next cycle, resulting in insufficient cooling effect of subsequent cooling water and affecting the pipe sizing. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a cooling mechanism for a pipe sizing device, which can further cool the circulating cooling water and ensure the cooling effect.

[0004] The technical solution of this utility model is as follows:

[0005] A cooling mechanism for a pipe sizing device includes:

[0006] A cooling box includes a box body and a refrigeration device and a cooling pool disposed inside the box body. The box body is provided with a cold water pipe connected to the refrigeration device. The inlet end of the cold water pipe is located outside the box body, and the outlet end extends to the top of the cooling pool.

[0007] A circulating water tank is located on one side of the cooling tank. The outside of the circulating water tank is provided with an inlet and an outlet. A drain pipe is provided on one side of the bottom of the circulating water tank.

[0008] The circulation pipe is located in the middle of the cooling pool, and the input and output ends of the circulation pipe extend through the box body to the outside of the box body respectively.

[0009] The conveying pipe includes pipe one and pipe two. Pipe one connects the inlet and the outlet of the circulation pipe, and pipe two connects the outlet and the inlet of the circulation pipe. A first water pump is installed on pipe two.

[0010] In a further technical solution, a liquid exchange pipe is also included. The bottom of the cooling pool is provided with a first liquid exchange port that connects to the outside of the tank. The circulating water tank is provided with a second liquid exchange port. The two ends of the liquid exchange pipe are respectively connected to the first liquid exchange port and the second liquid exchange port. A second water pump is provided on the liquid exchange pipe.

[0011] In a further technical solution, the middle part of the circulation tube is serpentine.

[0012] In a further technical solution, both the delivery pipe and the liquid exchange pipe are corrugated pipes.

[0013] In a further technical solution, a temperature controller electrically connected to the refrigeration equipment is provided on the side wall of the cooling pool.

[0014] In a further technical solution, the cabinet has a door on one side corresponding to the refrigeration equipment, and a transparent observation window is provided on the side of the door near the thermostat.

[0015] In a further technical solution, a level gauge for a cooling pool is provided on one side of the box.

[0016] In a further technical solution, the side of the housing closest to the refrigeration equipment is provided with a heat dissipation vent, and a cooling fan is installed inside the heat dissipation vent.

[0017] In a further technical solution, the outer side of the housing is provided with a dustproof net covering the heat dissipation vents.

[0018] The beneficial effects of this utility model are:

[0019] 1. The water in the cooling pool comes from the cold water pipe, which is connected to a water source. The refrigeration equipment can cool the water in the cold water pipe and put it into the cooling pool for later use. The water in the circulating water tank is used by the existing pipe sizing device to cool the pipes. After heat exchange, the water in the circulating water tank can be drawn by the first water pump, enter the circulating pipe through the second pipe, and exchange heat with the water in the cooling pool again to cool it down. Then it returns to the circulating water tank through the first pipe for the next cycle. This device further cools the circulating cooling water on the basis of the existing circulating water tank, ensuring the cooling effect and ensuring the normal operation of large pipe cooling and sizing.

[0020] 2. A fluid exchange pipe can be installed to connect the circulating water tank and the cooling pool. After the water in the circulating water tank has been circulating for a long time, the water in the cooling pool can be directly pumped into the circulating water tank. The original water in the circulating water tank, along with the impurities brought by multiple circulations, is discharged through the drain pipe. This setting can reduce the impurities in the cooling water in the circulating water tank and improve the cooling efficiency.

[0021] 3. The serpentine circulation tube has a large heat exchange area and high heat exchange efficiency;

[0022] 4. The corrugated pipe has good axial expansion and contraction capacity, which makes it easy to install circulating water tanks and cooling tanks. In addition, dirt does not easily accumulate inside the corrugated pipe, and the scale prevention effect is good.

[0023] 5. The thermostat allows for easy switching of the refrigeration equipment on or off according to the set temperature, ensuring that the water in the cooling pool remains within the specified temperature range, thereby further guaranteeing the cooling effect;

[0024] 6. The cooling fan can expel heat from the refrigeration equipment through the heat dissipation vents, and the dust filter prevents most dust from entering the cabinet, which is conducive to the stable operation of the refrigeration equipment. Attached Figure Description

Detailed Implementation

[0029] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0030] Example:

[0031] like Figures 1-2 As shown, a cooling mechanism for a pipe sizing device includes a circulating water tank 10, a circulating pipe 20, a delivery pipe, and a cooling box;

[0032] The cooling box includes a box body 40 and a refrigeration device 50 and a cooling pool 60 disposed within the box body 40. A cold water pipe 51, connected to the refrigeration device 50, is installed on the box body 40. The inlet end of the cold water pipe 51 is located outside the box body 40, and the outlet end extends to the top of the cooling pool 60. A circulating water tank 10, part of an existing pipe sizing device, is used for circulating cooling water. The circulating water tank 10 is located on one side of the cooling box, with an inlet and an outlet on its outer side. The bottom of the circulating water tank 10... A drain pipe 11 is provided on the side; the middle part of the circulation pipe 20 is located in the cooling pool 60, and the middle part of the circulation pipe 20 is serpentine. The serpentine circulation pipe 20 has a large heat exchange area and high heat exchange efficiency; the inlet and outlet of the circulation pipe 20 extend through the box 40 to the outside of the box 40 respectively; the conveying pipe includes pipe 1 31 and pipe 2 32. Pipe 1 31 connects the inlet and the outlet of the circulation pipe 20, and pipe 2 32 connects the outlet and the inlet of the circulation pipe 20. A first water pump 33 is provided on pipe 2 32;

[0033] In addition, the cooling mechanism also includes a liquid exchange pipe 70, the bottom of the cooling pool 60 is provided with a first liquid exchange port that connects to the outside of the box 40, the circulating water tank 10 is provided with a second liquid exchange port, the two ends of the liquid exchange pipe 70 are respectively connected to the first liquid exchange port and the second liquid exchange port, and a second water pump 71 is provided on the liquid exchange pipe 70.

[0034] Valves are installed at the input and output ends of the circulation pipe 20, the first liquid exchange port of the cooling pool 60, the input and output ports of the circulating water tank 10, the drain pipe 11 and the second liquid exchange port, respectively, and are opened and closed according to the actual use.

[0035] The working principle of the above technical solution is as follows:

[0036] The input end of the cold water pipe 51 is connected to a water source, and the refrigeration equipment 50 is turned on. The water in the cold water pipe 51 is cooled and then placed in the cooling pool 60 for later use. After the water in the circulating water tank 10 has undergone one circulation, the first water pump 33 is turned on to pump the water in the circulating water tank 10 into the circulating pipe 20 through the second pipe 32. The water then undergoes another heat exchange with the water in the cooling pool 60 to cool down, and returns to the circulating water tank 10 through the first pipe 31 for the next circulation. The liquid exchange pipe 70 connects the circulating water tank 10 and the cooling pool 60. After the water in the circulating water tank 10 has been circulating for a long time, the water in the cooling pool 60 can be directly pumped into the circulating water tank 10. The original water in the circulating water tank 10, along with the impurities brought by multiple circulations, is discharged through the drain pipe 11. This setting can reduce the impurities in the cooling water in the circulating water tank 10 and improve the cooling efficiency.

[0037] In another embodiment, the delivery pipe and the fluid exchange pipe 70 may be corrugated pipes.

[0038] The corrugated pipe has good axial expansion and contraction capacity, which makes it easy to install the circulating water tank 10 and the cooling tank. In addition, dirt does not easily accumulate inside the corrugated pipe, and the scale prevention effect is good.

[0039] In another embodiment, such as Figure 1-2 As shown, a temperature controller 52 electrically connected to the refrigeration equipment 50 is provided on the side wall of the cooling pool 60; a door 41 is provided on the side of the box body 40 corresponding to the refrigeration equipment 50, and a transparent observation window 42 is provided on the side of the door 41 near the temperature controller 52.

[0040] The temperature sensor of the thermostat 52 monitors the water temperature of the cooling pool 60. The thermostat 52 can easily turn the refrigeration equipment 50 on or off according to the set temperature to ensure that the water in the cooling pool 60 is kept within the specified temperature range, thereby further ensuring the cooling effect. The door 41 can be easily opened to maintain the refrigeration equipment 50, and the transparent observation window 42 makes it easy to observe the operation of the thermostat 52.

[0041] In another embodiment, such as Figure 1 As shown, a level gauge 61 for the cooling pool 60 is provided on one side of the housing 40. This allows for easy observation of the liquid level in the cooling pool 60 and timely replenishment of cooling water.

[0042] In another embodiment, such as Figure 2As shown, the cabinet 40 has a heat dissipation vent on the side near the refrigeration equipment 50, and a cooling fan 54 is installed inside the heat dissipation vent; a dustproof net 53 covering the heat dissipation vent is provided on the outside of the cabinet 40.

[0043] The cooling fan 54 can expel the heat from the cooling equipment 50 through the heat dissipation vent, and the dust filter 53 prevents most of the dust from entering the cabinet 40, which is conducive to the stable operation of the cooling equipment 50.

[0044] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
