Description

Technical Field

[0001] This utility model relates to the field of coating cooling technology, and in particular to a cooling water circulation system suitable for coating equipment. Background Technology

[0002] In vacuum coating processes, heat is generated within the coating equipment, requiring continuous cooling to ensure process requirements are met. Traditionally, cooling systems for vacuum coating connect the equipment directly to a tap water pipe. Water is forced into the cooling system by gravity, and the cooled water is then drained. Current market solutions utilize water-recycling cooling water circulation systems, typically employing cooling towers for water cooling and reuse. However, these towers generally have a constant cooling capacity. Fluctuations in the coating equipment's power output cause variations in heat generation. Using a constant-power cooling tower in such cases is insufficient for the variable-frequency processing of the coating equipment, leading to either over- or under-cooling of the water.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0021] The existing cooling water circulation system, which uses a cooling tower for cooling, is insufficient for the coating equipment 600 with variable frequency processing, resulting in either over- or under-cooling. Therefore, this invention proposes a cooling water circulation system suitable for coating equipment to solve the aforementioned technical problems.

[0022] like Figures 1 to 2 As shown, the cooling water circulation system of this utility model includes: a circulation module 100 and multiple cooling tower modules 200.

[0023] Each of the two adjacent cooling tower modules 200 is provided with a first control valve 300, which is used to control the flow of cooling water between the two adjacent cooling tower modules 200. The cooling tower module 200 at the beginning is provided with an inlet pipe 400 connected to the cooling water outlet of the coating equipment 600.

[0024] This embodiment limits the number of cooling tower modules 200 to three. In other embodiments, the number of cooling tower modules 200 may be four or more.

[0025] It is understandable that two adjacent cooling tower modules 200 are connected by a connecting pipe 310, and the first control valve 300 is installed on the connecting pipe 310.

[0026] The circulation module 100 of this utility model includes a circulation pipe 110 for connecting to the cooling water inlet of the coating equipment 600. A second control valve 500 is provided between each cooling tower module 200 and the circulation pipe 110. The second control valve 500 is used to control the flow of cooling water between each cooling tower and the circulation pipe 110.

[0027] In use, based on the operating power of the coating equipment 600, the opening and closing of multiple first control valves 300 and multiple second control valves 500 are controlled to control a set number of cooling tower modules 200 to operate in series with the coating equipment 600. At this time, water flows through the cooling tower modules 200 connected in series with the coating equipment 600 in sequence, achieving a multi-stage cooling effect to meet different cooling conditions. There is no need to adjust the power of the cooling tower modules 200; only the first control valves 300 and the second control valves 500 need to be controlled, making the operation simple.

[0028] The cooling tower module 200 of this utility model includes a cooling tower body 210, a cooling water tank 220 located at the bottom of the cooling tower body 210, a cooling tower packing 230, a water spray assembly 240, and a fan assembly 250 located inside the cooling tower body 210. The fan assembly 250, the cooling tower packing 230, and the water spray assembly 240 are arranged sequentially from top to bottom inside the cooling tower body 210. The inlet of the water spray assembly 240 at the beginning is connected to the cooling water outlet of the coating equipment 600, and the inlets of the other water spray assemblies 240 are connected to the water outlet of the first control valve 300. The cooling water tank 220 is connected to the water inlet of the first control valve 300 and the second control valve 500, respectively.

[0029] The working principle of the cooling tower module 200 is as follows: the water to be cooled is sprayed from top to bottom into the cooling tower packing 230 through the water spray assembly 240 to form a water film in the cooling tower packing 230, increasing the heat exchange area in contact with the air. At the same time, the fan assembly 250 is started to form flowing air in the cooling tower body 210. When the air passes through the cooling tower packing 230, it contacts the water for heat exchange to carry away the heat, thereby achieving the cooling of the water. After cooling, the water falls back into the cooling water tank 220 and enters the next cooling tower body 210 for cooling again, or flows into the circulation pipe 110 and directly returns to the coating equipment 600.

[0030] Furthermore, this embodiment also includes a water tank body 700, in which multiple partitions 710 are provided. The multiple partitions 710 are arranged at intervals to divide the water tank body 700 into multiple cooling water tanks 220. Multiple cooling tower bodies 210 are arranged at intervals on the top of the water tank body 700 to make the system more compact.

[0031] Each cooling tower module 200 in this embodiment also includes a cooling pump 260 located at the inlet of the water spray assembly 240. The cooling pump 260 provides power to the cooling water to achieve spraying, and at the same time pumps the cooling water in the cooling water tank 220 of the previous stage to the water spray assembly 240 of the next stage.

[0032] Meanwhile, the circulation pipe 110 in this embodiment is equipped with a circulation pump 111, which is used to pump the water in the cooling water tank 220 back to the coating equipment 600.

[0033] In this embodiment, the water inlet pipe 400 is equipped with a water inlet control valve 410, which controls the water output of the coating equipment 600.

[0034] The circulation pipe 110 is equipped with a circulation control valve 112, which controls the water intake of the coating equipment 600.

[0035] Each cooling water tank 220 in this embodiment is provided with a water filling channel 221 and a water filling control valve 2211. During use, the liquid level of the cooling water tank 220 needs to be monitored at all times. When the cooling water in the cooling water tank 220 decreases to the set value, the water filling control valve 2211 is opened to add water to the cooling water tank 220 to avoid water shortage.

[0036] Furthermore, each cooling water tank 220 in this embodiment is provided with a drainage channel 222, and the drainage channel 222 is provided with a drainage control valve 2221. When it is necessary to clean the system pipeline, the drainage control valve 2221 can be opened to drain the water in the corresponding cooling water tank 220.

[0037] The working principle of the cooling water circulation system in this embodiment is as follows: During use, according to the operating power of the coating equipment 600, if the coating equipment 600 is at its maximum power, all the first control valves 300 and the end second control valves 500 are opened, and the other second control valves 500 are closed. All the cooling tower modules 200 are controlled to operate in series with the coating equipment 600. At this time, water flows through all the cooling tower modules 200 in sequence to achieve a multi-stage cooling effect. If the coating equipment 600 is at minimum power, close all first control valves 300, open the second control valve 500 at the beginning, close the other second control valves 500, and control the cooling tower module 200 at the beginning to operate in series with the coating equipment 600. At this time, water flows through the cooling tower module 200 at the beginning for cooling and temperature reduction.

[0038] If the coating equipment 600 is operating between its maximum and minimum power, then the corresponding number of cooling tower modules 200 are controlled to operate in series with the coating equipment 600. At this time, water flows through the corresponding number of cooling tower modules 200 to cool down the water and meet different cooling conditions.

[0039] Therefore, this utility model does not require adjustment of the power of the cooling tower module 200; it only requires control of the first control valve 300 and the second control valve 500, making operation simple.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
