Description

Technical Field

[0001] This utility model relates to the field of dry ice cleaning technology, and in particular to a dry ice cleaning device. Background Technology

[0002] Dry ice cleaning machines are a new type of cleaning machine. The cleaning system uses high-pressure air to spray dry ice particles onto the surface of the workpiece that needs cleaning. The dry ice particles vaporize upon impact with the workpiece, losing momentum instantly. Simultaneously, a rapid heat exchange occurs between the dry ice particles and the workpiece surface, causing the particles to sublimate into gas. Utilizing the difference in volume between the workpiece and the dirt caused by temperature changes, as well as the micro-explosion of the gas produced by the sublimation and expansion of the dry ice particles, the dirt is detached from the workpiece surface. Dry ice cleaning does not produce any secondary wastewater or waste; only the rinsed dirt needs to be collected.

[0003] Most existing dry ice cleaning machines are portable cleaning machines, mainly consisting of an air compressor and a dry ice machine. The air compressor produces clean compressed air and supplies high-pressure air to the dry ice machine. The dry ice particles are accelerated in the high-pressure airflow and impact the surface of the workpiece to be cleaned. In use, the dry ice cleaning machine needs to be moved to a suitable position, the cleaning nozzle of the dry ice machine held and aimed at the area to be cleaned, and the cleaning position and angle must be constantly changed to complete the cleaning. This cleaning method cannot automatically adjust the cleaning position and angle, making operation inconvenient, increasing the workload of the operator, and resulting in low cleaning efficiency.

[0004] Therefore, there is an urgent need to provide a new type of dry ice cleaning equipment to solve the above-mentioned technical problems in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a dry ice cleaning device that can conveniently and quickly clean the surface of the workpiece using dry ice particles, resulting in higher cleaning efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The dry ice cleaning equipment includes an air compressor, a dry ice machine, a cleaning machine, and a conveying device. The air compressor is used to provide high-pressure gas. The dry ice machine stores dry ice particles, and the air compressor is connected to the dry ice machine. The cleaning machine includes a moving component and a cleaning nozzle. The cleaning nozzle is connected to the dry ice machine. The output end of the moving component is connected to the cleaning nozzle and drives the cleaning nozzle to move along a first direction and a second direction. The conveying device is used to move the workpiece to be cleaned along the first direction so that the workpiece to be cleaned can move to a position facing the cleaning nozzle.

[0008] Optionally, the cleaning machine further includes a cleaning chamber, in which the cleaning machine is disposed, and the conveying device is disposed through the cleaning chamber along the first direction.

[0009] Optionally, the moving component includes a first driving member and a second driving member, the first driving member being disposed on the inner wall of the cleaning chamber, the second driving member being disposed at the output end of the first driving member, and the cleaning nozzle being disposed at the output end of the second driving member; the first driving member drives the second driving member to move along the first direction, and the second driving member drives the cleaning nozzle to move along the second direction.

[0010] Optionally, the inner wall of the cleaning chamber is further provided with a support slide rail extending along the first direction, and the second drive member is provided with a support slider at one end along the second direction, the support slider being slidably connected to the support slide rail.

[0011] Optionally, the conveying device includes a conveyor line extending along the first direction, and the workpiece to be cleaned is placed on the conveyor line.

[0012] Optionally, the output end of the conveyor line is disposed on the support bracket, and the two ends of the workpiece to be cleaned along the first direction are connected to the support bracket.

[0013] Optionally, a rotary drive mechanism is provided below the conveyor line, which drives the workpiece to be cleaned to rotate along its own axis on the support bracket.

[0014] Optionally, the rotary drive mechanism includes a fixed bracket, a lifting drive component, and a rotary drive component. The lifting drive component is disposed on the fixed bracket, and the rotary drive component is connected to the output end of the lifting drive component and driven by the lifting drive component to move along the second direction. The output end of the rotary drive component is used to connect the workpiece to be cleaned.

[0015] Optionally, the output end of the rotary drive is provided with a friction wheel, which is driven to rotate along its own axis, and the outer peripheral wall of the friction wheel can abut against the outer peripheral wall of the workpiece to be cleaned.

[0016] Optionally, the air compressor includes an air tank, a refrigerated dryer, and a screw air compressor. The refrigerated dryer and the screw air compressor are both located on top of the air tank. The screw air compressor generates compressed air and connects to the air tank via a pipeline. The refrigerated dryer is connected to the air tank via a pipeline and is used to dry the compressed gas in the air tank. The outlet of the refrigerated dryer is connected to the dry ice machine.

[0017] Beneficial effects:

[0018] The dry ice cleaning equipment in this embodiment drives the cleaning nozzle to move along the first and second directions by setting a moving component, and cooperates with the conveying device to transport the workpiece to be cleaned. This effectively solves the technical defects of existing dry ice cleaning machines that rely on manual hand-held adjustment of the nozzle position and angle, resulting in inconvenient operation, large workload and low cleaning efficiency. On the one hand, the moving component, as the core driving part of the cleaning machine, connects to the cleaning nozzle at its output end and drives it to move along the first and second directions. This achieves automated adjustment of the cleaning nozzle position, replacing traditional manual hand operation. It eliminates the need for operators to manually change the cleaning position and angle, significantly reducing labor intensity and improving operational convenience. On the other hand, the conveying device moves the workpiece to be cleaned along the first direction to the position directly opposite the cleaning nozzle, achieving automatic workpiece transport and positioning. This avoids the tedious process of manual handling and positioning of workpieces, further reducing manual intervention and optimizing the operation process. Finally, the coordinated operation of the moving component and the conveying device forms an automated cleaning system. The conveying device transports the workpiece to be cleaned to the cleaning station, and the moving component drives the nozzle to move in the first and second directions to cover the surface of the workpiece. The matching of their spatial movement directions enables precise cleaning of different areas of the workpiece, effectively shortening the cleaning cycle of a single workpiece and significantly improving cleaning efficiency. This dry ice cleaning equipment can conveniently and quickly clean the surface of the workpiece using dry ice particles, resulting in higher cleaning efficiency. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] The first direction described in this embodiment is: Figure 1 The X direction shown is the horizontal direction and the length direction of the conveyor 400; the second direction is... Figure 1 The Y direction shown is the vertical direction and the height direction of the dry ice cleaning equipment; the first direction and the second direction are perpendicular to each other.

[0032] like Figure 1As shown, the dry ice cleaning equipment includes an air compressor 100, a dry ice machine 200, a cleaning machine 300, and a conveying device 400. The air compressor 100 is used to provide high-pressure gas; the dry ice machine 200 stores dry ice particles, and the air compressor 100 is connected to the dry ice machine 200; the cleaning machine 300 includes a moving component and a cleaning nozzle 320, the cleaning nozzle 320 is connected to the dry ice machine 200, the output end of the moving component is connected to the cleaning nozzle 320 and drives the cleaning nozzle 320 to move along a first direction and a second direction; the conveying device 400 is used to move the workpiece 10 to be cleaned along the first direction so that the workpiece 10 to be cleaned can move to a position facing the cleaning nozzle 320.

[0033] The dry ice cleaning equipment in this embodiment drives the cleaning nozzle 320 to move along the first and second directions by setting a moving component, and cooperates with the conveying device 400 to transport the workpiece 10 to be cleaned. This effectively solves the technical defects of the existing dry ice cleaning machine 300, which relies on manual hand-held adjustment of the nozzle position and angle, resulting in inconvenient operation, large workload and low cleaning efficiency. On the one hand, the moving component, as the core driving part of the cleaning machine 300, connects its output end to the cleaning nozzle 320 and drives it to move along the first and second directions. This achieves automated adjustment of the position of the cleaning nozzle 320, replacing traditional manual hand operation. It eliminates the need for operators to manually change the cleaning position and angle, significantly reducing labor intensity and improving operational convenience. On the other hand, the conveying device 400 moves the workpiece 10 to be cleaned along the first direction to a position directly opposite the cleaning nozzle 320, achieving automatic conveying and positioning of the workpiece. This avoids the tedious process of manually handling and positioning the workpiece, further reducing manual intervention and optimizing the operation process. Finally, the coordinated operation of the moving component and the conveying device 400 forms an automated cleaning system. The conveying device 400 transports the workpiece 10 to the cleaning station, and the moving component drives the nozzle to move in the first and second directions to cover the surface of the workpiece 10. The matching of their spatial movement directions enables precise cleaning of different areas of the workpiece 10, effectively shortening the cleaning cycle of a single workpiece and significantly improving cleaning efficiency. This dry ice cleaning equipment can conveniently and quickly use dry ice particles to clean the surface of the workpiece 10, resulting in higher cleaning efficiency.

[0034] Optionally, the cleaning machine 300 further includes a cleaning chamber 330, in which the cleaning machine 300 is disposed, and the conveying device 400 is disposed through the cleaning chamber 330 along the first direction. The cleaning chamber 330 and the conveying device 400 passing through it create a relatively enclosed cleaning space. The cleaning chamber 330 effectively isolates sublimation gases and detached dirt generated during dry ice cleaning, preventing them from diffusing into the external environment. This protects operators from the effects of low-temperature gases or dust and avoids environmental pollution. Simultaneously, the conveying device 400 passing through the cleaning chamber 330 enables continuous feeding and unloading of the workpiece 10 to be cleaned, ensuring the continuity of the automated cleaning process and further improving system integration and operational safety.

[0035] In this embodiment, the moving component includes a first driving member 311 and a second driving member 312. The first driving member 311 is disposed on the inner wall of the cleaning chamber 330, the second driving member 312 is disposed at the output end of the first driving member 311, and the cleaning nozzle 320 is disposed at the output end of the second driving member 312. The first driving member 311 drives the second driving member 312 to move along the first direction, and the second driving member 312 drives the cleaning nozzle 320 to move along the second direction. The hierarchical driving structure of the first driving member 311 and the second driving member 312 constitutes a two-dimensional motion control system for the cleaning nozzle 320. The first driving component 311 is fixed to the inner wall of the cleaning chamber 330 to provide basic installation support. Its output end drives the second driving component 312 to move along the first direction. The second driving component 312 then drives the cleaning nozzle 320 to move along the second direction, forming a linkage adjustment mechanism similar to the XY axis. This mechanism can precisely control the cleaning nozzle 320 at any position in the plane, achieving full coverage cleaning of multiple areas on the workpiece surface. It solves the problems of low adjustment accuracy and limited coverage of manual handheld nozzles, and significantly improves the accuracy and flexibility of the cleaning position.

[0036] It should be noted that the combination of the first drive component 311 and the second drive component 312 can also be replaced by a multi-axis robotic arm, which can be used to directly grasp the cleaning nozzle 320 and change its cleaning position. This will not be elaborated here.

[0037] Optionally, the inner wall of the cleaning chamber 330 is further provided with a support slide rail 341 extending along the first direction, and a support slider 342 is provided at one end of the second drive member 312 along the second direction. The support slider 342 is slidably connected to the support slide rail 341. When the first drive member 311 drives the second drive member 312 to move along the first direction, the support slider 342 slides synchronously along the slide rail, effectively dispersing the self-weight load of the second drive member 312 and the cleaning nozzle 320, providing a stable guide and load-bearing structure for the movement of the moving components, avoiding movement swaying or deviation caused by the cantilever structure, ensuring the trajectory accuracy of the cleaning nozzle 320 during two-dimensional movement, thereby ensuring the accuracy of the cleaning position and improving the stability of the cleaning quality.

[0038] Please continue to refer to this. Figure 1 The aforementioned conveying device 400 includes a conveyor line 410 extending along the first direction, on which the workpiece 10 to be cleaned is placed. Compared to intermittent or manual handling, the conveyor line 410 enables continuous and uniform conveying of workpieces. Combined with the automated movement of the cleaning nozzle 320, it forms an integrated "conveying-cleaning" assembly line operation, reducing workpiece waiting time. Simultaneously, the conveyor line 410 has a simple structure, is easy to maintain, and can adapt to the stable conveying of workpieces of different sizes, improving the equipment's versatility and continuous operation capability.

[0039] Optionally, the output end of the aforementioned conveyor line 410 is disposed on the support bracket 420, and the two ends of the workpiece 10 to be cleaned along the aforementioned first direction are connected to the support bracket 420. By fixing the two ends of the workpiece 10 to be cleaned along the first direction, the support bracket 420 achieves precise positioning and stable support of the workpiece at the cleaning station. For workpieces that are prone to shaking, such as long strips or cylinders, connecting the two ends to the support bracket 420 can prevent them from tilting or shifting during conveying or cleaning, ensuring that the central axis of the workpiece and the movement trajectory of the cleaning nozzle 320 maintain a preset relative position, so that the cleaning nozzle 320 can accurately align with the area to be cleaned, avoiding cleaning blind spots or repeated cleaning caused by workpiece displacement, and improving positioning accuracy and cleaning efficiency.

[0040] In this embodiment, the air compressor 100 includes an air tank 110, a refrigerated dryer 120, and a screw air compressor 130. The refrigerated dryer 120 and the screw air compressor 130 are both disposed on the top of the air tank 110. The screw air compressor 130 is used to generate compressed air and is connected to the air tank 110 through a pipeline. The refrigerated dryer 120 is connected to the air tank 110 through a pipeline and is used to dry the compressed gas in the air tank 110. The outlet of the refrigerated dryer 120 is connected to the dry ice machine 200. The screw air compressor 130 has high air production efficiency and stable pressure. The compressed air it produces is stored in the air tank 110 to avoid air supply fluctuations affecting the dry ice spray intensity. The refrigerated dryer 120 dries the gas in the air tank 110 to remove moisture and impurities, preventing moisture from entering the dry ice machine 200 and causing dry ice particles to clump or block the pipeline, thus ensuring the continuity and uniformity of dry ice spray. The layout design that integrates the three components on the top of the air tank 110 optimizes the equipment space occupation, improves the system compactness and maintenance convenience, and provides a stable air source guarantee for the dry ice cleaning effect.

[0041] Please refer to further information. Figure 2 A rotary drive mechanism 430 is provided below the aforementioned conveyor line 410. The rotary drive mechanism 430 is used to drive the workpiece 10 to be cleaned to rotate along its own axis on the aforementioned support bracket 420. When the workpiece 10 to be cleaned is placed on the support bracket 420, the support bracket 420 is supported by rollers provided at both ends of its top along the first direction, making the rotation of the workpiece 10 to be cleaned smoother. Combining the two-dimensional motion of the moving component driving the cleaning nozzle 320 with the linear conveying of the conveying device 400, the rotation of the workpiece 10 to be cleaned allows all areas of its circumference to be directly facing the cleaning nozzle 320. For example, for a cylindrical insulating core rod workpiece, no additional angle adjustment is required from the cleaning nozzle 320; the rotation of the workpiece 10 to be cleaned can cover its entire outer circumference, effectively solving the problem of incomplete cleaning coverage of complex-shaped workpieces, expanding the equipment's adaptability to irregularly shaped workpieces 10 to be cleaned, and improving the comprehensiveness of cleaning.

[0042] Optionally, the rotary drive mechanism 430 includes a fixed bracket 431, a lifting drive component 432, and a rotary drive component 433. The lifting drive component 432 is disposed on the fixed bracket 431, and the rotary drive component 433 is connected to the output end of the lifting drive component 432 and driven by the lifting drive component 432 to move along the second direction. The output end of the rotary drive component 433 is used to connect to the workpiece 10 to be cleaned. The lifting drive component 432 drives the rotary drive component 433 to move along the second direction (i.e., the vertical direction). The position of the rotary drive component 433 can be adjusted according to the size of the workpiece 10 to be cleaned, and the contact state (contact drive or disengagement avoidance) can be adjusted to avoid interfering with the conveying of the workpiece 10 to be cleaned. The rotary drive component 433 directly outputs rotational power to ensure that the workpiece's rotation speed is stable and adjustable, adapting to the cleaning needs of workpieces 10 with different materials and degrees of dirt, and improving the flexible control capability of the equipment.

[0043] In this embodiment, a friction wheel 434 is provided at the output end of the rotary drive 433. The friction wheel 434 is driven to rotate along its own axis, and the outer peripheral wall of the friction wheel 434 can abut against the outer peripheral wall of the workpiece 10 to be cleaned. The friction wheel 434 at the output end of the rotary drive 433 achieves transmission by abutting the workpiece with its outer peripheral wall. It drives the workpiece to rotate in a non-rigid contact manner, which has significant advantages in adaptability and protection. Specifically, the friction wheel 434 avoids the risk of squeezing or scratching the workpiece surface due to mechanical hard connection, and is especially suitable for workpieces 10 with fragile surfaces or irregular shapes to be cleaned. At the same time, the outer peripheral wall of the friction wheel 434 can adapt to the friction drive requirements of workpieces 10 with different diameters to be cleaned. Stable transmission can be achieved by adjusting the abutment force, reducing the requirements for the dimensional accuracy of the workpiece 10 to be cleaned, simplifying the clamping process, and improving the convenience of operation.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
