A sink cooling water self-circulation cooling device

Abstract

This invention provides a self-circulating cooling device for a water tank, belonging to the field of plastic processing technology. The device includes a water tank, circulating cooling water pipes, and a fan for drying material strips. The water tank has an outlet at the bottom and an inlet at the top. The circulating cooling water pipes are arranged in a trapezoidal spiral below the fan outlet, with the inlet end connected to the outlet and the outlet end connected to the inlet. A motor is located near the inlet end of the circulating cooling water pipes. This invention utilizes the fan to blow cool air to cool the water in the circulating cooling water pipes. Simultaneously, since the fan is mainly used for drying the material strips, water from the strips drips onto the outer surface of the circulating cooling water pipes during the drying process. As the water evaporates from the outer surface of the circulating cooling water pipes, it also carries away some heat, achieving heat dissipation. This effectively solves the problem of water waste and improves efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of plastic processing technology, and specifically relates to a water tank cooling water self-circulation cooling device. Background Technology

[0002] In the plastics processing industry, extruders, cooling water tanks, fans, and pelletizers are important and indispensable equipment, especially in the color masterbatch industry. The manufacture of color masterbatch requires the mixing and processing of pigments, carrier resins, and additives, followed by granulation. During the granulation process, a cooling process is involved, requiring the extrusion equipment to be equipped with cooling water tanks, drying fans, and pelletizers. Under normal circumstances, the water in the cooling water tank needs to be circulated for cooling or centrally cooled by a cooling tower. The former, which uses circulating water for cooling, wastes a lot of water resources, while the latter, which uses a cooling tower for centralized cooling, is relatively limited. When the equipment is underutilized or only one line is operating, the cooling tower still needs to work to ensure the water in the tank is cooled, which is a great waste of resources, inefficient, energy-intensive, and complex to operate. Utility Model Content

[0003] The purpose of this invention is to solve the problems existing in the prior art and provide a water tank cooling water self-circulation cooling device, which can effectively solve the waste of water resources and improve efficiency.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model provides a water tank cooling water self-circulation cooling device, including a water tank, circulating cooling water pipes and a fan for air drying material strips;

[0006] The water tank has an outlet at the bottom and an inlet at the top;

[0007] The circulating cooling water pipe is placed below the air outlet of the fan in a trapezoidal spiral shape. The inlet end of the circulating cooling water pipe is connected to the outlet, and the outlet end of the circulating cooling water pipe is connected to the inlet. A motor is installed near the inlet end of the circulating cooling water pipe.

[0008] The further improvement of this utility model is as follows:

[0009] The water cooling device also includes a support frame, which is placed below the air outlet of the fan.

[0010] The further improvement of this utility model is as follows:

[0011] The support frame is a frustum-shaped frame structure, with the cross-sectional area of ​​its upper end face being smaller than that of its lower end face.

[0012] The further improvement of this utility model is as follows:

[0013] The circulating cooling water pipe is spirally coiled in a trapezoidal shape within the support frame.

[0014] The further improvement of this utility model is as follows:

[0015] The water cooling device for the water tank also includes an air collection box, which has openings at both the top and bottom.

[0016] The further improvement of this utility model is as follows:

[0017] The upper opening of the air collection box is located directly below the air outlet of the fan;

[0018] The lower opening of the air collection box is connected to the top of the support frame.

[0019] The further improvement of this utility model is as follows:

[0021] The further improvement of this utility model is as follows:

[0022] A water tank filter screen is installed at the water outlet of the water tank.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] In this invention, water in the water tank is drawn into the circulating cooling water pipe by a motor. Cool air from the fan is collected by a collector and blown onto the circulating cooling water pipe to cool it down, thus cooling the water inside. Simultaneously, since the fan is primarily used for drying the material strips, water from the strips falls onto the outer surface of the circulating cooling water pipe during the drying process. As this water evaporates, it carries away some heat, further dissipating heat from the water inside the pipe. This invention utilizes the airflow from drying the material strips to cool the water in the tank, effectively solving water waste, improving efficiency, eliminating the need for additional cooling equipment, reducing energy consumption and costs, increasing resource utilization, and simplifying operation.

[0025] In this invention, a support frame is set up and placed below the air outlet of the fan. The circulating cooling water pipe is spirally coiled in a trapezoidal shape inside the support frame. The support frame is set as a frustum-shaped structure with a smaller top and a larger bottom, which helps to dissipate heat and ensures that the water in the circulating cooling water pipe reaches the cooling temperature. At the same time, it can also provide some support for the circulating cooling water pipe, so that the contact surface area of ​​the air blown out by the fan is larger, thereby improving the heat dissipation effect.

[0026] In this invention, a filter screen is installed on the circulating cooling water pipe. The filter screen is fixed to the circulating cooling water pipe by a flange and sealed by a sealing sleeve. Different mesh sizes and materials of filter screens can be used as needed to ensure that the circulating water is clean and pure, avoid material contamination, and ensure that the circulating water pipe is unobstructed. At the same time, it is easy to disassemble, clean and replace the screen. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings:

[0031] like Figure 1 and Figure 2 As shown, this utility model provides a water tank cooling water cooling device, including a water tank 1, a circulating cooling water pipe 9 and a fan 7 for air drying material strips;

[0032] The water tank 1 is provided with an outlet 3 at the bottom and an inlet 4 at the top;

[0033] The circulating cooling water pipe 9 is placed below the air outlet of the fan 7 in a trapezoidal spiral. The inlet end of the circulating cooling water pipe 9 is connected to the water outlet 3, and the outlet end of the circulating cooling water pipe 9 is connected to the water inlet 4. A motor 6 is installed near the inlet end of the circulating cooling water pipe 9.

[0034] Driven by the motor 6, the water in the water tank enters the circulating cooling water pipe 9. Since the circulating cooling water pipe 9 is placed below the air outlet of the fan 7 in a trapezoidal spiral, the air blown by the fan 7 dissipates heat and cools the circulating cooling water pipe 9, thereby cooling the water in the circulating cooling water pipe 9. The cooled water enters the water tank 1 through the water inlet 4, completing the water circulation cooling.

[0035] In this utility model, the circulating cooling water pipe 9 is made of stainless steel, which can avoid rust and corrosion, and also has a certain strength to make the structure more stable. The circulating cooling water pipe 9 is coiled in a trapezoidal shape below the air outlet of the fan 7, which increases the contact surface area of ​​the air and makes the heat dissipation more efficient. At the same time, different materials or shapes of circulating cooling water pipes can be replaced according to different needs and requirements. Different cooling water pipe sizes can be selected according to the size of the production site, the production volume, etc.

[0036] The blower 7 used in this invention is used to air dry the material strips during the granulation process. The large volume of air is only used to blow away the water on the surface of the material strips and has no other use, which is a waste of resources. This invention concentrates the air volume that blows over the material strips onto the circulating cooling water pipe 9 to achieve the function of heat dissipation and cooling.

[0037] In a preferred embodiment of this utility model, the water cooling device further includes a support frame 11, which is placed below the air outlet of the fan 7. The support frame 11 is a frustum-shaped frame structure, with the cross-sectional area of ​​its upper end face being smaller than that of its lower end face. The circulating cooling water pipe 9 is spirally coiled in a trapezoidal shape inside the support frame 11. The support frame 11 is designed as a frustum-shaped frame structure, which is smaller at the top and larger at the bottom, which helps to dissipate heat and ensures that the water in the circulating cooling water pipe 9 reaches the cooling temperature. At the same time, it can provide some support for the circulating cooling water pipe 9, so that the contact surface area of ​​the air blown out by the fan 7 is larger, thereby improving the heat dissipation effect.

[0038] In a preferred embodiment of this utility model, the water cooling device further includes an air collection box 8, which has openings at both the top and bottom. The upper opening of the air collection box 8 is located directly below the air outlet of the fan 7. The material strip support roller 10 is located between the air outlet of the fan 7 and the air collection box 8. The lower opening of the air collection box 8 is connected to the top of the support frame 11. This utility model concentrates the airflow blowing over the material strip through the air collection box 8 and blows it onto the circulating cooling water pipe 9, thereby achieving the function of heat dissipation and cooling. At the same time, the fan blows away the moisture on the surface of the material strip, which falls onto the circulating cooling pipe 9 through the air collection box 8. The evaporation of moisture is more conducive to the heat dissipation and cooling of the circulating cooling water pipe 9.

[0039] In a preferred embodiment of this utility model, a filter screen 5 is provided on the circulating cooling water pipe. The filter screen 5 is located between the inlet end of the circulating cooling water pipe 9 and the motor 6. Specifically, the filter screen 5 is fixed to the circulating cooling water pipe 9 by a flange and sealed by a sealing sleeve. Different mesh sizes and materials of filter screens can be used as needed to ensure that the circulating water is clean and pure, avoid material contamination, and ensure the unobstructed flow of the circulating cooling water pipe. At the same time, it is easy to disassemble, clean, and replace the screen.

[0040] In a preferred embodiment of this utility model, a water tank filter screen 2 is provided at the water outlet 3 of the water tank to filter out impurities in the water and prevent the circulating cooling water pipe 9 from becoming clogged.

[0041] The working principle of this utility model's water tank cooling device is as follows:

[0042] The material strip slides on the material strip support roller 10 under traction and is dried by the air blown out of the air outlet of the fan 7. At the same time, the water in the water tank 1 enters the circulating cooling water pipe 9 under the drive of the motor 6. Since the circulating cooling water pipe 9 is placed below the air outlet of the fan 7 in a trapezoidal spiral, the airflow blowing over the material strip is collected by the air collection box 8 and blown onto the circulating cooling water pipe 9 to dissipate heat and cool it. At the same time, the water blown off the surface of the material strip by the fan 7 falls onto the circulating cooling water pipe 9 through the air collection box. The evaporation of water is more conducive to the heat dissipation and cooling of the circulating cooling water pipe 9, further realizing the cooling of the water in the circulating cooling water pipe 9. The cooled water enters the water tank 1 through the water inlet 4 to complete the water circulation cooling.

[0043] In this invention, water in the water tank 1 enters the circulating cooling water pipe 9 through the action of the motor 6. The cold air from the fan is concentrated through the air collector 8 and blown onto the circulating cooling water pipe 9 to cool it down, thereby cooling the water inside the circulating cooling water pipe 9. At the same time, since the fan 7 is mainly used for drying the material strips, water on the material strips will fall onto the outer surface of the circulating cooling water pipe 9 during the drying process. When the water on the outer surface of the circulating cooling water pipe 9 evaporates, it will also take away some heat, thus achieving the function of heat dissipation for the water inside the circulating cooling water pipe 9. This invention uses the air from drying the material strips to cool the water in the water tank, which can effectively solve the waste of water resources, improve efficiency, and eliminate the need for additional cooling equipment. It reduces energy consumption and costs, improves resource utilization, and is simple to operate.
