Description

Technical Field

[0001] This utility model relates to the field of vacuum coating equipment technology, specifically to an integrated auxiliary device for a vacuum coating machine. Background Technology

[0002] Vacuum coating machines are primarily used for surface coating of various metal materials to enhance their properties. Their main structure includes a vacuum coating chamber and a coating source. During operation, the workpiece needs to be heated to improve material adhesion, but overheating must be prevented; therefore, a cooling system, such as a cooling water circuit, is required. However, when the vacuum chamber is opened after completing a batch of coatings, the high surface temperature of the chamber walls or the target material allows external air to enter, causing condensation. This makes it very difficult to re-evacuate the vacuum chamber and affects coating quality. Therefore, the vacuum chamber and target material need to be insulated during vacuum chamber opening to prevent condensation. Furthermore, coating equipment is bulky and requires a stable and large supply of cooling and insulation water during long-term operation, as well as an air supply. Consequently, coating machines require various external auxiliary devices, which are not only cumbersome to install and operate but also energy-inefficient, necessitating improvements. Utility Model Content

[0003] The purpose of this invention is to provide an integrated auxiliary device for a vacuum coating machine that is easy to install and energy-saving.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An integrated auxiliary device for a vacuum coating machine, comprising:

[0006] A water purifier is used to produce pure water and store it in a pure water tank.

[0007] The cold water tank is connected to the pure water tank through a first water passage for receiving and storing pure water, and is provided with a second water passage for outputting pure water and a first water pump. The second water passage has a first interface for connecting to the cooling water inlet of the coating machine.

[0008] A chiller is used to cool the pure water in the chilled water tank to a set temperature;

[0009] The hot water tank is provided with a second interface connected to the cooling water outlet of the coating machine for receiving and storing heated pure water, and is provided with a third water channel for outputting heated pure water and a second water pump. The third water channel has a third interface for connecting to the inlet of the heat preservation water channel of the coating machine.

[0010] The first cooling tower is connected to the hot water tank via the fourth water channel and the third water pump. It is used to receive excess pure water from the hot water tank. The first cooling tower is equipped with a first cooling fan, and the cooled pure water is then transported to the cold water tank via the fifth water channel.

[0011] In a preferred embodiment, the system further includes an air compressor, a gas storage tank for storing the high-pressure gas produced by the air compressor, an air passage interface for outputting the high-pressure gas from the gas storage tank to the coating machine, and a dryer for drying the high-pressure gas.

[0012] In a preferred embodiment, the cold water tank further outputs a sixth water path for cooling the air compressor and the chiller, and the sixth water path is delivered to a second cooling tower via a fourth water pump, the second cooling tower being equipped with a second cooling fan.

[0013] In a preferred embodiment, the second cooling tower delivers the cooled pure water back to the cold water tank via a seventh water channel.

[0014] In a preferred embodiment, the system further includes a tap water tank that provides a water source for the water purifier.

[0015] In a preferred embodiment, the system further includes a double-layer frame, wherein the pure water tank, the tap water tank, the first cooling tower and the second cooling tower are located on the upper layer of the frame, while the cold water tank, the hot water tank, the chiller and the air compressor are located on the lower layer of the frame.

[0016] The beneficial effects of this invention are as follows: Pure water is produced by a pure water system and used to provide cooling and insulation water for the coating machine, preventing corrosion or scaling blockage in the cooling or insulation water circuits; a cold water tank provides cooling water for the cooling water circuit, and the heated pure water is returned to the hot water tank to provide hot water for the insulation water circuit, resulting in better energy saving; because the cooling and insulation water circuits operate for different times, and the insulation water circuit operates for a shorter time than the cooling water circuit, the cooling water circuit requires a larger volume of pure water. Therefore, excess hot water is cooled by the first cooling tower and returned to the cold water tank, ensuring a rapid supply of room temperature pure water, thereby reducing the refrigeration pressure on the chiller and further improving energy saving. This auxiliary equipment integrates the water supply for the coating machine's cooling and insulation water circuits, and by circulating both cooled and heated pure water, it not only simplifies installation and operation due to its high integration but also saves more energy.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] refer to Figures 1 to 3 This embodiment provides an integrated auxiliary device for a vacuum coating machine, including...

[0023] A water purifier 1 is used to produce pure water and store it in a pure water tank 11, wherein there can be one or more pure water tanks 11.

[0024] The cold water tank 2 is connected to the pure water tank 11 through a first water passage for receiving and storing pure water, and is provided with a second water passage 21 for outputting pure water and a first water pump 22. The second water passage 21 has a first interface 23 for connecting to the cooling water inlet of the coating machine.

[0025] The chiller 3 is used to cool the pure water in the cold water tank 2 to a set temperature. In this embodiment, the chiller 3 is installed on the water inlet of the cold water tank 2. In other embodiments, the chiller 3 can also be installed on the water outlet of the cold water tank 2.

[0026] The hot water tank 4 is provided with a second interface 41 connected to the cooling water outlet of the coating machine for receiving and storing heated pure water, and is provided with a third water channel 42 for outputting heated pure water and a second water pump 43. The third water channel 42 has a third interface 44 for connecting to the heat preservation water inlet of the coating machine.

[0027] The first cooling tower 5 is connected to the hot water tank 4 via the fourth water channel and the third water pump 52, and is used to receive excess pure water in the hot water tank 4. The first cooling tower 5 is equipped with a first cooling fan 51, and then the cooled pure water is transported to the cold water tank 2 via the fifth water channel.

[0028] Pure water is produced by the pure water system 1 and used to provide cooling and insulation water for the coating machine, preventing corrosion or scaling blockage in the cooling and insulation water circuits. The cold water tank 2 provides cooling water for the cooling water circuit, and the heated pure water is returned to the hot water tank 4 to provide hot water for the insulation water circuit, resulting in better energy efficiency. Because the cooling and insulation water circuits operate for different durations, with the insulation water circuit operating for a shorter time, the cooling water circuit requires a larger volume of pure water. Therefore, excess hot water is cooled by the first cooling tower 5 and returned to the cold water tank 2, ensuring a rapid supply of room-temperature pure water. This reduces the cooling pressure on the chiller 3, further improving energy efficiency. This auxiliary equipment integrates the water supply for both the coating machine's cooling and insulation water circuits. By circulating both cooled and heated pure water, the high degree of integration simplifies installation and operation, and also enhances energy efficiency.

[0029] In a preferred embodiment, the auxiliary equipment further includes an air compressor 6, a gas storage tank 61 for storing the high-pressure gas produced by the air compressor 6, a gas interface for outputting the high-pressure gas from the gas storage tank 61 to the coating machine, and a dryer 62 for drying the high-pressure gas. This provides a gas source for the coating machine.

[0030] In a preferred embodiment, the cold water tank 2 further outputs a sixth water path for cooling the air compressor 6 and the chiller 3. This sixth water path is then pumped to a second cooling tower 7 via a fourth water pump 72. The second cooling tower 7 is equipped with a second cooling fan 71. Cooling the air compressor 6 and chiller 3 via the sixth water path, compared to existing decentralized auxiliary equipment, avoids shutdowns of the air compressor 6 and chiller 3 due to high temperatures during operation, thus improving the stability of equipment operation.

[0031] In a preferred embodiment, the second cooling tower 7 in this embodiment transports the cooled pure water back to the cold water tank 2 via the seventh water path. Similarly, the heated pure water after being cooled by the air compressor 6 and the chiller 3 is cooled by the second cooling tower 7 and then flows back to the cold water tank 2, reducing the refrigeration pressure of the chiller 3 and further improving the energy-saving effect.

[0032] In a preferred embodiment, the auxiliary equipment further includes a tap water tank 8 that provides a water source for the water purifier 1. The water purifier 1 can be replenished with purified water in a timely manner, ensuring long-term operation without shutdown.

[0033] In a preferred embodiment, the auxiliary equipment further includes a double-layer frame 9. The pure water tank 11, the tap water tank 8, the first cooling tower 5, and the second cooling tower 7 are located on the upper layer of the frame 9, while the cold water tank 2, the hot water tank 4, the chiller 3, and the air compressor 6 are located on the lower layer of the frame 9. Using a double-layer frame 9 not only reduces the equipment's footprint, but also allows the pure water in the pure water tank 11, the tap water tank 8, the first cooling tower 5, and the second cooling tower 7 to flow naturally into the cold water tank 2 and the hot water tank 4 on the lower frame 9 by gravity, eliminating the need for an additional water pump and further simplifying the equipment structure.

[0034] The above description does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
