[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4 As shown, this utility model provides an energy-saving water circulation cooling device for plastic granulation, including a cooling water tank 1, a circulation pump 4, a heat dissipation device 2, a filter device 3, and a temperature control device 101. The top of the cooling water tank 1 is provided with a cooling chamber 102, and the bottom of the cooling chamber 102 is provided with a condenser pipe 202 connected to the heat dissipation device 2. The cooling water tank 1 is provided with an inlet 104 on one side and an outlet 103 at the bottom. The input end of the circulation pump 4 is connected to the outlet 103 of the cooling water tank 1 through a first pipe 401, and the output end of the circulation pump 4 is connected to the cooling water inlet 104 of the plastic granulator through a second pipe 402.

[0024] During the plastic granulation process, the plastic granulator generates a large amount of heat, which needs to be removed by cooling equipment to ensure normal operation. When this energy-saving water circulation cooling equipment starts working, the cooling water from the outlet 103 at the bottom of the cooling water tank 1 is transported to the cooling inlet 104 of the plastic granulator through the first pipe 401 by the circulation pump 4. The cooling water absorbs heat inside the plastic granulator, and after its temperature rises, it flows out from the cooling outlet 103 of the plastic granulator.

[0025] The hot water returns to the cooling water tank 1 through pipes. A condenser pipe 202, connected to the heat dissipation device 2, is installed in the cooling chamber 102 at the top of the cooling water tank 1. As the hot water flows through the condenser pipe 202, heat is transferred to the heat dissipation device 2. The heat dissipation fins 201 in the heat dissipation device 2 increase the heat dissipation area. The cooling fans 203, symmetrically installed on both sides of the heat dissipation fins 201, accelerate airflow through forced convection, dissipating the heat from the heat dissipation fins 201 into the surrounding environment, thus gradually cooling the hot water flowing through the condenser pipe 202.

[0026] The heat dissipation device 2 includes heat dissipation fins 201 and a cooling fan 203. The heat dissipation fins 201 are symmetrically arranged on both sides of the cooling water tank 1, and the cooling fan 203 is symmetrically installed on both sides of the heat dissipation fins 201. The filter device 3 is located between the cooling water tank 1 and the circulating pump 4. The filter device 3 is connected to the first pipe 401. The temperature control device 101 includes a temperature sensor and a controller. The temperature sensor is installed on the first pipe 401 near the cooling water inlet 104 of the plastic granulator. The controller is electrically connected to the temperature sensor, the cooling fan 203, and the circulating pump 4.

[0027] During the process of cooling water flowing from cooling water tank 1 to circulating pump 4, the filter device 3 plays a role. The outer shell 301 of the filter device 3 is equipped with multiple layers of filter screens 302, and the mesh size gradually decreases from the water inlet end to the water outlet end. It can intercept impurity particles of different sizes in sequence, filter the cooling water, prevent impurities from entering the circulating pump 4 and the plastic granulator, and ensure smooth water flow and normal operation of the equipment.

[0028] The temperature control device 101 plays a crucial regulatory role throughout the cooling process. A temperature sensor is installed on the first pipe 401 near the cooling water inlet 104 of the plastic granulator to monitor the temperature of the cooling water entering the granulator in real time and transmit the temperature signal to the controller. When the temperature sensor detects that the water temperature is too high, the controller controls the cooling fan 203 to increase its speed to enhance heat dissipation. Simultaneously, it adjusts the frequency of the circulating pump 4 (variable frequency pump) to increase the cooling water circulation flow rate and accelerate heat exchange. When the water temperature drops to a suitable range, the controller reduces the speed of the cooling fan 203 and the frequency of the circulating pump 4 to reduce energy consumption.

[0029] In addition, the flow regulating valve on the second pipe 402 is electrically connected to the controller. The controller can adjust the opening of the flow regulating valve according to actual needs to precisely control the amount of cooling water entering the plastic granulator. The drain valve at the bottom of the cooling water tank 1 can be opened during equipment maintenance to remove impurities and dirt deposited at the bottom of the tank. The water quality monitoring device located between the filter device 3 and the circulating pump 4 is electrically connected to the controller to monitor the cooling water quality in real time. When the water quality does not meet the standards, the controller can issue an alarm to remind personnel to perform water treatment or water replacement.

[0030] Furthermore, the filter device 3 includes a housing 301 and a multi-layer filter screen 302 disposed within the housing 301. The mesh size of the multi-layer filter screen 302 gradually decreases from the inlet end to the outlet end. The multi-layer filter screen 302 design of the filter device 3 effectively intercepts impurities in the cooling water, preventing impurities from entering the circulation system, reducing wear and blockage of components such as the circulation pump 4 and internal pipes of the plastic granulator, lowering the probability of equipment failure, extending equipment lifespan, and reducing the frequency and cost of equipment maintenance.

[0031] Furthermore, the second pipe 402 is equipped with a flow regulating valve, which is electrically connected to the controller. Under the control of the controller, the flow regulating valve on the second pipe 402 can precisely adjust the amount of cooling water entering the plastic granulator, making the cooling process more precise and controllable, further improving the cooling effect, and meeting the cooling requirements of the plastic granulator under different operating conditions.

[0032] Furthermore, the cooling water tank 1 is equipped with a drain port at its bottom, and a drain valve is installed at the drain port. The drain port and drain valve at the bottom of the cooling water tank 1 facilitate the regular cleaning of impurities and dirt deposited at the bottom of the tank, maintaining the cleanliness of the interior of the cooling water tank 1, ensuring the quality and cooling effect of the cooling water, and reducing the risk of equipment failure due to the accumulation of dirt in the tank.

[0033] Furthermore, the system also includes a water quality monitoring device located between the filter device 3 and the circulating pump 4, which is electrically connected to the controller. The water quality monitoring device monitors the cooling water quality in real time and issues an alarm promptly if the water quality fails to meet standards, reminding staff to perform water treatment or water replacement operations. This prevents water quality issues from affecting the normal operation and cooling effect of the equipment, while also providing data support for equipment maintenance, making maintenance work more targeted and timely.

[0034] Furthermore, the circulating pump 4 is a variable frequency pump, and the controller controls the circulation flow rate of the cooling water by adjusting the frequency of the variable frequency pump. The use of a variable frequency pump 4, with the controller adjusting its frequency to control the circulation flow rate of the cooling water, allows for precise adjustment of the cooling water flow rate according to different operating states and heat dissipation requirements of the plastic granulator. This minimizes the energy consumption of the circulating pump 4 while meeting cooling requirements, achieving energy-saving operation.

[0035] Furthermore, the cooling fan 203 is mounted on one side of the heat dissipation fins 201 via an adjustable mounting bracket. The temperature sensor in the temperature control device 101, in conjunction with the controller, can precisely control the speed of the cooling fan 203 and the frequency of the circulation pump 4 based on the actual temperature of the cooling water. When the water temperature is low, the speed of the cooling fan 203 and the frequency of the circulation pump 4 are reduced, decreasing the energy consumption of the equipment and avoiding the energy waste caused by the continuous high-power operation of traditional cooling equipment.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
