Description

Technical Field

[0001] This invention relates to dry ice cleaning equipment, and more particularly to an integrated dry ice cleaning machine. Background Technology

[0002] Dry ice cleaners work by using high-pressure air to propel dry ice particles at high speed onto the surface of the object to be cleaned. Upon contact with the dirt, the dry ice particles sublimate and expand instantly, generating a powerful peeling force that quickly removes the dirt. This cleaning method eliminates the need for chemical solvents and leaves no residue after cleaning.

[0003] To facilitate portability and outdoor cleaning, current dry ice cleaners come with a built-in air supply mechanism, integrating the air compressor and air tank into the dry ice cleaner, eliminating the need for an external air compressor and meeting the requirements for outdoor or air-free environments.

[0004] During operation, integrated dry ice cleaning machines generate significant heat from their internal air compressor and main electrical control system, necessitating effective heat dissipation measures to maintain normal operation. Cooling the compressed air is particularly crucial, as it's used to mix with dry ice particles. Excessive compressed air temperature accelerates the sublimation of the dry ice particles during mixing, impacting cleaning efficiency and increasing dry ice consumption, thus raising cleaning costs. Therefore, heat dissipation design is a critical consideration when designing integrated dry ice cleaning machines. Summary of the Invention

[0005] This invention aims to effectively solve the heat dissipation problem of integrated dry ice cleaning machines through reasonable heat dissipation design, thereby ensuring the efficient operation and service life of the equipment.

[0006] To solve the above-mentioned technical problems, the present invention provides an integrated dry ice cleaning machine, including a frame and an ice storage chamber, an ice mixing system, an air supply system, a spraying system and an electronic control system integrated in the frame;

[0007] The ice storage chamber is used to store dry ice particles, and the ice mixing system is connected to the ice storage chamber to receive the dry ice particles; the spraying system is used to spray dry ice particles onto the surface to be cleaned; the electrical control system is used to control the operation of the cleaning machine.

[0008] The air supply system includes an air compressor and an air storage device. The air storage device is connected to the ice mixing system through a delivery pipe. The delivery pipe is used to deliver compressed air to the ice mixing system to mix with dry ice particles. The delivery pipe is wound around the ice storage chamber in a winding shape with an extended path for heat exchange.

[0009] In a preferred embodiment, the winding shape with the extended path is a spiral or serpentine structure.

[0010] In a preferred embodiment, the delivery pipe is wrapped around the four walls of the ice storage chamber or the delivery pipe is coiled around one side wall of the ice storage chamber.

[0011] In a preferred embodiment, the delivery pipe is located inside or outside the ice storage chamber.

[0012] In a preferred embodiment, a heat dissipation device is also provided inside the frame for heat dissipation of the air compressor host.

[0013] In a preferred embodiment, the air compressor is disposed on the lower side of the ice storage chamber, and the heat dissipation device is installed on the outer wall of the ice storage chamber.

[0014] In a preferred embodiment, the spraying system includes a spray gun and a nozzle, and the ice mixing system is externally connected to an ice spraying interface; the ice spraying interface is connected to the spray gun.

[0015] In a preferred embodiment, the ice storage chamber is an inverted quadrangular pyramid, and the ice mixing system is located below the ice storage chamber; the ice storage chamber is connected to the ice mixing system.

[0016] In a preferred embodiment, the frame includes a folding push rod.

[0017] In a preferred embodiment, the bottom of the frame is provided with at least four casters.

[0018] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0019] 1. By using the ice storage chamber to exchange heat through the delivery pipe, the low-temperature dry ice absorbs the heat of the compressed air, thereby achieving heat dissipation of the compressed air in the delivery pipe. This ensures that the compressed air maintains a low temperature during spraying, enhances the low-temperature embrittlement effect of the dry ice particles, and improves cleaning efficiency.

[0020] 2. The delivery pipe is routed around the ice storage chamber for heat exchange. Through a reasonable heat dissipation design, the heat dissipation problem of the integrated dry ice cleaning machine is effectively solved, ensuring the efficient operation and service life of the equipment.

[0021] 3. By routing the delivery pipe around the ice storage chamber, the distributed space of the ice storage chamber is made more efficient, resulting in a more compact equipment structure and saving space.

[0022] 4. The design of the delivery pipe winding around the ice storage chamber increases the heat exchange area and improves the heat exchange efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0032] refer to Figures 1-5This embodiment provides an integrated dry ice cleaning machine, including a frame 1 and an ice storage chamber 2, an ice mixing system 3, an air supply system, a spraying system, and an electrical control system integrated within the frame 1. The ice storage chamber 2 is installed above the frame 1 and is used to store dry ice particles. The ice mixing system 3 is installed below the ice storage chamber 2 and communicates with it, receiving the dry ice particles. The dry ice particles fall into the ice mixing system 3 and mix with compressed air. The spraying system is used to spray dry ice particles onto the surface to be cleaned. The electrical control system is used to control the operation of the cleaning machine. The air supply system includes an air compressor 4 and an air storage device 5, which are located to the side and below the ice storage chamber 2. Figure 3 The air compressor 4 is located on the front side of the frame 1, and the air storage device 5 is located on the left or right side of the frame 1. The air storage device 5 is connected to the ice mixing system 3 through the delivery pipe 6. The delivery pipe 6 is used to deliver compressed air to the ice mixing system 3 to mix with dry ice particles.

[0033] By integrating the ice storage chamber 2, ice mixing system 3, air supply system, injection system and electrical control system into the same frame 1, the equipment is made compact, efficient and portable.

[0034] The electrical control system is used to control the operating parameters of the cleaning machine, such as spray pressure and dry ice flow. The electrical control system includes a switch button 13, an emergency stop button 14, a pressure adjustment button 15, and an indicator light 16, which facilitates operation and observation by personnel.

[0035] like Figure 2 The delivery pipe 6 is wound around the outer wall of the ice storage chamber 2 for heat exchange, utilizing the low-temperature dry ice to absorb the heat of the compressed air and improve the utilization rate of dry ice. Specifically, the delivery pipe 6 is wound around the outer wall of the ice storage chamber 2 in a spiral, serpentine, or other meandering shape to increase the heat exchange area, further improve the heat exchange efficiency, and reduce the heat of the compressed air. Other meandering shapes are other winding shapes with extended paths. In this embodiment, the delivery pipe 6 can be located on the outside or inside of the ice storage chamber 2. Located inside, it can directly exchange heat with the dry ice particles, resulting in better cooling efficiency. Located on the outside, it optimizes the overall structural layout without changing the structure of the ice storage chamber 2, and still achieves heat exchange with the compressed air.

[0036] The delivery pipe 6 can be installed around the four outer walls of the ice storage chamber 2 or coiled around one outer wall of the ice storage chamber 2 (e.g., Figure 2 This extends the contact time between compressed air and ice storage chamber 2, improving cooling efficiency. Simultaneously, the dry ice particles stored in ice storage chamber 2 facilitate heat exchange with the compressed air. The large quantity of dry ice particles stored in the ice storage chamber results in minimal temperature increase upon contact with hot air, thus enabling continuous and effective absorption of heat from the compressed air, maintaining a low-temperature environment, and reducing sublimation loss of the dry ice particles.

[0037] like Figure 4 The frame 1 is also equipped with a heat dissipation device for cooling the air compressor unit 4. A heat dissipation device, preferably a powerful fan 7, is installed above the air compressor unit 4 to reduce the heat generated during operation and extend the equipment's service life. The heat dissipation device is installed on the outer wall of the ice storage chamber 2, optimizing the overall equipment layout, and simultaneously utilizing low-temperature dry ice in conjunction with the fan 7 to achieve powerful cold air cooling of the air compressor unit 4.

[0038] like Figure 5 The spraying system includes a spray gun 8 and a nozzle. The ice mixing system 3 is externally connected to an ice spraying interface 31, which is connected to the spray gun 8 to ensure that the dry ice particles and compressed air can be efficiently sprayed onto the surface to be cleaned, thereby achieving efficient cleaning.

[0039] The ice storage chamber 2 is an inverted quadrangular pyramid shape. This conical structure facilitates the automatic descent of dry ice particles into the mixing system under gravity, reducing blockages. An opening 21 is located at the top of the ice storage chamber 2 for releasing dry ice particles; a cover plate is fitted to the opening for easy opening and closing. The mixing system 3 is located below the ice storage chamber 2, and the ice storage chamber 2 is connected to the mixing system 3. This structural design helps ensure smooth transport of dry ice particles, reducing losses during storage and transport.

[0040] The frame 1 includes a folding push rod 11 and at least four casters 12 located at its bottom, facilitating the movement and positioning of the equipment and improving its portability and ease of operation. The portable design of the folding push rod 11, combined with the casters 12, enables flexible movement and storage of the equipment.

[0041] In this embodiment, a compact, efficient, and portable device is achieved through a reasonable layout. The outer wall space of the ice storage chamber 2 is utilized effectively for heat dissipation, resulting in a more compact structure, space saving, and enhanced heat dissipation efficiency.

[0042] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
