Description

Technical Field

[0001] This utility model relates to the field of large-volume concrete construction, specifically to an energy-saving variable frequency circulating cooling device for a temperature control system of large-volume concrete. Background Technology

[0002] During the construction of large-volume concrete, the internal temperature of the concrete rises rapidly due to the heat of cement hydration. If this temperature is not controlled effectively and promptly, it can lead to excessive temperature differences between the inside and outside of the concrete, resulting in temperature cracks and affecting the durability and safety of the concrete structure. Currently, a common method for temperature control in large-volume concrete is the cooling water pipe method, which involves embedding cooling water pipes inside the concrete and using circulating water to remove heat from the concrete. However, existing circulating cooling devices have certain shortcomings in terms of cooling efficiency and water resource utilization, and cannot adequately meet the actual needs of temperature control in large-volume concrete.

[0003] Therefore, it is necessary to develop a high-efficiency, energy-saving variable frequency circulating cooling device to improve the performance of temperature control systems for large-volume concrete. Summary of the Invention

This device can effectively improve cooling efficiency, reduce energy consumption, and realize the recycling of water resources, thereby better controlling the internal temperature of large-volume concrete and reducing the generation of temperature cracks.

[0005] To achieve the above objectives, this utility model provides an energy-saving variable frequency circulating cooling device for a large-volume concrete temperature control system.

[0016] Preferably, the water storage tank is equipped with a filtration device, which is used to filter impurities in the water flowing down from the radiator to prevent the impurities from entering other devices.

[0017] Preferably, the bottom of the housing is provided with a shock-absorbing pad, which is used to reduce the vibration and noise generated when the circulating water pump is working.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] (a) Installation of the device

[0029] First, install the radiator (2) in a suitable position inside the casing, ensuring its stability. Then, connect the inlet channel (1) and outlet channel (9) to both ends of the radiator (2), and connect the outlet of the cooling water pipe assembly (10) and the system water tank (8) through the water supply pipe (11). Next, install the spray system (3) at the top of the radiator (2) and connect the water collector (4) to the spray system (3). Place the water storage tank (5) at the bottom of the radiator (2), connect the water storage tank (5) to the water collector (4) through the internal pipe (6), and install the circulating water pump (7). Finally, install the shock-absorbing pad (12) at the bottom of the casing.

[0030] (II) Work Process

[0031] When the large-volume concrete temperature control system is started, hot water enters the radiator (2) from the cooling water pipe assembly (10) through the inlet channel (1). At this time, the circulating water pump (7) starts working, pumping water from the storage tank (5) to the collector (4), and then spraying the radiator (2) through the spray system (3) for cooling. The corrugated heat dissipation fins on the outer surface of the radiator (2) increase the heat dissipation area and accelerate the dissipation of heat. At the same time, the water sprayed from the spray system (3) evaporates on the surface of the radiator, taking away a large amount of heat and further improving the cooling effect. The cooled water flows back to the system water tank (8) through the outlet channel (9). The filter device in the storage tank (5) filters out impurities in the water to ensure the cleanliness of the circulating water. The circulating water pump (7) automatically adjusts its speed according to the water level in the storage tank (5) or the spraying requirements of the spray system (3) to achieve energy-saving operation. The shock-absorbing pad (12) reduces the vibration and noise generated when the circulating water pump (7) is working.

[0032] (III) Maintenance and Management

[0033] Regularly check the opening and closing of the ball valve to ensure it controls the flow and volume of water. Check the filter for blockages; if any are found, clean or replace it promptly. Regularly clean the dust and debris from the surface of the radiator (2) to ensure effective heat dissipation. Check the operating status and motor temperature of the circulating water pump (7); if any abnormalities are found, repair or replace it promptly.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
