Description

Technical Field

[0001] This utility model relates to the field of industrial cleaning technology, and in particular to a blizzard cleaning system. Background Technology

[0002] Currently, most products in our daily lives originate from industrial environments and are contaminated during processing, transportation, and prolonged exposure to air. Contamination of high-precision workpieces, such as circuit boards, can significantly reduce their functionality and efficiency, making surface cleaning a pressing issue. With continuous advancements in cleaning technology, carbon dioxide snow cleaning technology has emerged as an environmentally friendly and highly efficient cleaning method. Carbon dioxide snow cleaning is not only environmentally friendly in both its preparation and cleaning processes but also eliminates the need for wastewater treatment, effectively preventing secondary pollution. Throughout the cleaning process, only carbon dioxide undergoes a phase change, with no other substances generated. Therefore, it has a wide range of applications, including cleaning electrical components, optical components, crystals, ceramics, medical equipment, and defense equipment. For example, while water cleaning of electrical components can damage their circuitry, carbon dioxide drying cleaning does not affect the circuitry. Furthermore, compared to solvent cleaning, this method leaves no detectable residues, especially for precision samples such as silicon and indium phosphide wafers, patterned cores, hybrid chips, optical devices, and polymers, where there is no structural damage. Carbon dioxide is also readily available, inexpensive, safe, and reliable. However, how to make carbon dioxide snow cleaning convenient, controllable, and with adjustable proportions to ensure safety and stability during the process, improve cleaning quality, and conserve carbon dioxide usage remains a problem that needs to be solved by those in the field.

[0030] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0031] like Figures 1-7As shown, this embodiment provides a blizzard cleaning system, including a controller 10, a hose 20, an air pipe 30, a solenoid valve 40, a throttle valve 50, and a cleaning nozzle 60. The two ends of the hose 20 are connected to the controller 10 and the solenoid valve 40, respectively, for conveying liquid carbon dioxide. The two ends of the air pipe 30 are connected to the controller 10 and the cleaning nozzle 60, respectively, for conveying compressed air. The solenoid valve 40, the throttle valve 50, and the cleaning nozzle 60 are connected in sequence. The liquid carbon dioxide can undergo a phase change in the cleaning nozzle 60 to form snowflake-shaped carbon dioxide. The snowflake-shaped carbon dioxide and the compressed air can mix to form a mixed blizzard-like fluid, which can be sprayed out from the spray head 64 of the cleaning nozzle 60.

[0032] Specifically, in this embodiment, the controller 10, solenoid valve 40, and throttle valve 50 can control the delivery volume and speed of liquid carbon dioxide and compressed air, respectively. In the cleaning nozzle 60, the liquid carbon dioxide undergoes a phase change to form snowflake-like carbon dioxide, which is then mixed with compressed air to form a mixed blizzard-like fluid. This mixed blizzard-like fluid is sprayed out through the spray head 64 for cleaning, effectively improving cleaning quality. Furthermore, controlling the delivery ratio of compressed air and carbon dioxide can change the ratio of the mixed blizzard-like fluid, thereby ensuring cleaning effectiveness while reducing carbon dioxide usage, saving energy, and expanding the applicability. The blizzard cleaning system of this embodiment has a simple structure and is easy to operate, effectively ensuring safety and stability during the cleaning process.

[0033] The specific structure of the blizzard cleaning system in this embodiment is described below.

[0034] like Figure 1 As shown, the blizzard cleaning system in this embodiment includes a controller 10, a hose 20, an air pipe 30, a solenoid valve 40, a throttle valve 50, and a cleaning nozzle 60. It utilizes the phase change of liquid carbon dioxide to form snowflake-shaped carbon dioxide, which is then mixed with compressed air to form a blizzard-like fluid for spraying and cleaning, thereby improving cleaning efficiency. The ratio of snowflake-shaped carbon dioxide to compressed air can be adjusted according to different cleaning conditions, thus ensuring cleaning effectiveness while reducing carbon dioxide consumption. Specifically, in this embodiment, both ends of the hose 20 are connected to the controller 10 and the solenoid valve 40 respectively to facilitate the delivery of liquid carbon dioxide, and both ends of the air pipe 30 are connected to the controller 10 and the cleaning nozzle 60 respectively to facilitate the delivery of compressed air. Furthermore, the solenoid valve 40, the throttle valve 50, and the cleaning nozzle 60 are connected sequentially to control the delivery speed of the liquid carbon dioxide. Furthermore, liquid carbon dioxide can undergo a phase change in the cleaning nozzle 60 to form snowflake-shaped carbon dioxide, which can be mixed with compressed air to form a mixed blizzard-like fluid, and can be sprayed out at the spray head 64 at the end of the cleaning nozzle 60 to achieve the effect of blizzard cleaning.

[0035] like Figures 1-2 As shown, in this embodiment, the controller 10 is equipped with a first outlet 11, a second outlet 12, a first inlet 13, a second inlet 14, a control panel 15, a pressure gauge 16, a pressure regulating valve 17, and a handle 18. The controller 10 also includes a power switch 101, a power socket 102, a control cable connector 103, a vent 104, and a fan 105. Optionally, the first outlet 11 is used to deliver liquid carbon dioxide, with a hose 20 connected to it. The second outlet 12 is used to deliver compressed air, with a tubing 30 connected to it. Exemplarily, both the first outlet 11 and the second outlet 12 are located on the front of the controller 10, while the first inlet 13 and the second inlet 14 are located on the back of the controller 10. Specifically, the first inlet 13 is used to deliver carbon dioxide into the controller 10, where it is processed inside the controller 10 to form liquid carbon dioxide for direct subsequent use. Alternatively, liquid carbon dioxide can be directly delivered through the first inlet 13, allowing the controller 10 to control the output of the liquid carbon dioxide. Specific configurations can be adjusted as needed. Furthermore, the second inlet 14 is used to deliver compressed air to the controller 10, so that the delivery parameters of liquid carbon dioxide and compressed air can be set by the controller 10.

[0036] Specifically, in this embodiment, the controller 10 is equipped with a control screen 15, which is a touch screen. This allows operators to set the corresponding delivery parameters, ratios, etc., on the control screen 15 to suit different cleaning situations and expand its applicability. Correspondingly, operators can observe the pressure in real time through the pressure gauge 16 and manually adjust it through the pressure regulating valve 17. Specific usage methods can be set as needed and will not be elaborated here. For example, the control screen 15, pressure gauge 16, and pressure regulating valve 17 are all located on the front of the controller 10. Furthermore, the front of the controller 10 is also equipped with a control cable connector 103, enabling remote control, etc.

[0037] Combination Figure 1 and Figure 2 As shown, in this embodiment, a power switch 101 and a power socket 102 are provided on the back of the controller 10 to control the on / off state of the controller 10 and ensure power support for the entire blizzard cleaning system. Optionally, a fan 105 is also provided on the back of the controller 10 to dissipate heat from internal circuit components and ensure stable operation. Specifically, several ventilation holes 104 are provided on the top of the controller 10 to allow communication between the inside of the controller 10 and the outside, improving heat dissipation. Furthermore, two handles 18 are provided on the top of the controller 10, and the two handles 18 are arranged opposite each other, so that operators can stably carry the entire blizzard cleaning system using the two handles 18. Figure 4 and Figure 5 As shown, in this embodiment, the delivery status of liquid carbon dioxide into the cleaning nozzle 60 can be adjusted by the solenoid valve 40 and the throttle valve 50 to meet different cleaning needs.

[0038] like Figure 6 and Figure 7 As shown, in this embodiment, the cleaning nozzle 60 includes a carbon dioxide connector 61, a nozzle body 62, an air connector 63, and a spray head 64. The carbon dioxide connector 61 includes a connector body 611 and a phase change nozzle 612. Optionally, the cleaning nozzle 60 may also include a carbon dioxide channel 601, a blizzard channel 602, an air channel 603, an air annular cavity 604, a mixing cavity 605, and a spray channel 606. Specifically, the carbon dioxide connector 61, the nozzle body 62, and the spray head 64 are connected sequentially, and the air connector 63 is located between the carbon dioxide connector 61 and the spray head 64 and connected to the nozzle body 62. The throttle valve 50 is connected to the carbon dioxide connector 61, and the air pipe 30 is connected to the air connector 63. Thus, liquid carbon dioxide can enter through the carbon dioxide connector 61, undergo a phase change to form snowflake-shaped carbon dioxide, and then enter the nozzle body 62. Compressed air can enter through the air connector 63 and mix with the snowflake-shaped carbon dioxide in the spray head 64 before being sprayed out for cleaning.

[0039] In this embodiment, the throttle valve 50 is connected to the inlet end of the connector body 611, the phase change nozzle 612 is installed at the outlet end of the connector body 611, and the carbon dioxide channel 601 is disposed in the connector body 611. Liquid carbon dioxide enters the carbon dioxide channel 601 through the throttle valve 50 and undergoes phase change to form snowflake-shaped carbon dioxide after passing through the phase change nozzle 612. For example, the phase change nozzle 612 is configured with a conical structure, and the inner diameter of the lower end of the phase change nozzle 612 is smaller than the inner diameter of the upper end. Furthermore, the outer side of the phase change nozzle 612 is provided with external threads, and the top end of the nozzle body 62 is provided with internal threads. The phase change nozzle 612 is screwed to the top of the nozzle body 62 to prevent leakage of liquid carbon dioxide during the phase change process. Furthermore, the side of the nozzle body 62 has a protruding interface, and an air connector 63 is connected to the interface. The air channel 603 is disposed within the interface, allowing compressed air to enter the air channel 603 through the air connector 63. Furthermore, an inner cylinder is provided inside the nozzle body 62, and the top of the inner cylinder is screwed to the bottom of the phase change nozzle 612. The blizzard channel 602 is disposed in the inner cylinder, so that snowflake-shaped carbon dioxide can directly enter the blizzard channel 602. Furthermore, an annular cavity is formed between the outer side of the inner cylinder and the inner side of the nozzle body 62, which is the air annular cavity 604, and the air channel 603 is connected to the air annular cavity 604, so that compressed air can enter the air annular cavity 604.

[0040] Specifically, the air annular cavity 604 is arranged around the outside of the blizzard channel 602, and the two are not connected, but their bottoms are both connected to the mixing cavity 605. Thus, snowflake-shaped carbon dioxide enters the mixing cavity 605 through the blizzard channel 602, and compressed air enters the mixing cavity 605 through the air annular cavity 604. Further, the snowflake-shaped carbon dioxide and compressed air are mixed in the mixing cavity 605 to form a mixed blizzard-like fluid. Specifically, the mixing cavity 605 is a conical cavity, and the mixing cavity 605 and the injection channel 606 are interconnected, so that the mixed blizzard-like fluid can be ejected from the injection head 64 through the injection channel 606. For example, the inner diameter of the mixing cavity 605 on the side away from the injection channel 606 is larger than the inner diameter on the side connected to the injection channel 606, thereby ensuring the spraying effect of the mixed blizzard-like fluid under compressed air flow. For example, the injection head 64 and the air connector 63 are both connected to the nozzle body 62 by screws, thereby ensuring the overall stability of the cleaning nozzle 60 and facilitating disassembly, replacement, and maintenance.

[0041] Therefore, in this embodiment, the ratio of carbon dioxide to compressed air can be adjusted by the controller 10, thereby meeting different working conditions and improving the applicability of the cleaned surfaces. Simultaneously, by mixing the compressed air, the consumption of carbon dioxide can be reduced while ensuring cleaning effectiveness. For example, an air heating and carbon dioxide temperature-maintaining structure can be added to the blizzard cleaning system to improve mixing efficiency. Furthermore, liquid carbon dioxide can be transformed into snowflake-shaped carbon dioxide particles through the phase change nozzle 612, and then flow through the blizzard channel 602 to the spray head 64. Compressed air enters the spray head 64 and mixes with the particles, forming a high-speed blizzard-like fluid of air and carbon dioxide particles. This fluid impacts the cleaning surface, utilizing the micro-explosion phenomenon generated by the sublimation effect of carbon dioxide to clean the soiled areas, thereby improving cleaning efficiency and quality.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
