[0049] Please refer to Figure 1-Figure 5 The present invention provides a dry ice cutting jet machine to solve the problems of low cutting efficiency and easy ice blockage of the existing dry ice cutting jet machine.

[0050] For details, please refer to Figure 1 A three-dimensional diagram of a dry ice cutting jet machine provided by an embodiment of the present invention, Figure 2 The figure is an internal stereogram of a dry ice cutting spraying machine provided by an embodiment of the present invention, wherein the dry ice cutting spraying machine comprises: a frame 10, a pressure box 20, a cutting module 30 and a material transfer module 40, wherein an ice outlet 22 is provided at the bottom of the pressure box 20, wherein the ice outlet 22 is connected to an ice outlet pipe (not shown), and wherein the ice outlet 22 is arranged opposite to the cutting module 30 so that the dry ice 21 cut by the cutting module 30 is ejected along the ice outlet pipe after passing through the ice outlet 22. The frame 10 is used as a support frame of the entire device to provide a stable installation foundation for the dry ice cutting spraying machine. The pressure box 20 is arranged inside the frame 10 and is a key component for accommodating the dry ice 21. The internal space thereof is used to place the dry ice 21 to be cut. The cutting module 30 is fixed inside the pressure box 20 to cut the dry ice 21 and cut the large block of dry ice 21 into fragments or particles that meet the subsequent spraying requirements. The material transfer module 40 is arranged inside the pressure box 20 and is connected to the cutting module 30 to push the dry ice 21 so that the dry ice 21 can fit closely with the cutting module 30, ensuring that the cutting operation can be carried out smoothly and efficiently. An ice outlet 22 is arranged at the bottom of the pressure box 20, and the ice outlet 22 is connected to the ice outlet pipe, and the ice outlet The opening 22 corresponds to the position of the cutting module 30, so that the cut dry ice 21 can smoothly pass through the ice outlet 22 into the ice outlet pipe for subsequent processing. The entire cutting process is carried out in the sealed pressure box 20. The sealing design keeps a certain pressure in the pressure box 20, effectively suppressing the sublimation of the dry ice 21 before the cutting is completed, ensuring that the dry ice 21 is cut in a suitable state, and also providing the necessary pressure conditions for the dry ice 21 to mix with the high-pressure gas in the pressure box 20 at the ice outlet 22 after cutting. The cutting module 30 gradually cuts the dry ice 21 into the required fragments or particles, preparing for subsequent mixing and injection with the high-pressure gas. At the ice outlet 22, the cut dry ice 21 is fully mixed with the high-pressure gas to form a mixture of dry ice 21 and the high-pressure gas, and further mixed evenly in the ice outlet pipe, and finally ejected from the end of the pipe in a uniform state under the impetus of the high-pressure gas, achieving effective effects on the target area.

[0051] Specifically, the pressure box 20 is arranged inside the frame 10, and the pressure box 20 is used to accommodate dry ice 21. The cutting module 30 is fixed inside the pressure box 20, and the cutting module 30 is used to cut the dry ice 21. The material moving module 40 is arranged inside the pressure box 20, and the material moving module 40 is connected to the cutting module 30. The material moving module 40 is used to move the dry ice 21 so that the dry ice 21 is close to the cutting module 30. Through the coordinated cooperation of the cutting module 30 and the material moving module 40 in the pressure box 20, the cutting process of the dry ice 21 is efficient and orderly. The material moving module 40 ensures that the dry ice 21 is closely attached to the cutting module 30, and the cutting module 30 can accurately and quickly cut the dry ice 21 into a suitable shape and particle size. The pressure environment in the sealed pressure box 20 and the mixing with the high-pressure gas at the ice outlet 22 and the uniform mixing and spraying mechanism in the ice outlet pipe ensure that the dry ice 21 can be continuously, stably and evenly sprayed to the target area, greatly improving the efficiency of the entire dry ice 21 cutting and spraying process, and effectively reducing the operation time. Since the ice blocks and the cutting module 30 are placed inside the sealed pressure box 20 and maintain a certain pressure, the sublimation of the dry ice 21 during the cutting process is effectively suppressed. Compared with cutting in an open environment, the loss caused by the sublimation of the dry ice 21 is greatly reduced, ensuring that more dry ice 21 can be effectively cut and used for subsequent spraying operations, thereby improving the utilization rate of the dry ice 21. The cutting module 30 can accurately cut the dry ice 21 blocks into dry ice 21 particles, improve the quality of dry ice 21 processing, and thus improve the effect of the entire operation. This structural design based on ice cutting by the cutting module 30 and high-pressure gas blowing in the pressure box 20 has good applicability and can meet the ever-evolving industrial application needs.

[0052] As a further improvement of the present invention, see Figure 3The dry ice cutting jet machine also includes a control valve module 50; the control valve module 50 is arranged at the bottom of the frame 10, and the control valve module 50 includes a control component 51, a control component driving component 52 and a control pipe 53, and the control pipe 53 is connected to the ice outlet pipe. Through the coordinated work of the control component 51 and the control component driving component 52 of the control valve module 50, the flow rate and flow rate of the mixture of dry ice 21 and high-pressure gas can be accurately adjusted. In different application scenarios, such as cleaning or treating surfaces of different areas and different degrees of contamination, the spraying amount and spraying speed of dry ice 21 can be accurately adjusted according to actual needs to ensure the best operation effect, which not only avoids the waste of dry ice 21, but also ensures the adequacy of the operation. The connection between the control pipe 53 and the ice outlet pipe and the effective control of the flow of the mixture by the control part 51 help maintain the stability of the entire dry ice 21 cutting and spraying process. By accurately controlling the flow rate and flow rate, it is possible to avoid problems such as uneven and discontinuous operation caused by sudden changes in the amount or speed of dry ice 21 spraying, thereby ensuring the smooth progress of the operation process and improving the quality and efficiency of the operation. At the same time, in order to keep the ice outlet pipe unobstructed, after the dry ice 21 is sprayed, the cutting module 30 is temporarily stopped and the control part 51 is turned on, and the gas rushes out of the ice outlet pipe and the control pipe 53 to remove residual ice, thereby reducing abnormalities such as blockage of dry ice 21 and wear of spare parts.

[0053] As a further improvement of the present invention, see Figure 4The cutting module 30 includes a cutting chamber 31, a cutting disc 32 and a driving disc 33; the cutting chamber 31 includes a first cutting hole 311 and a second cutting hole 312 which are arranged opposite to each other, the driving disc 33 is accommodated in the first cutting hole 311, the cutting disc 32 is accommodated in the second cutting hole 312, and the driving disc 33 is fixedly connected to the cutting disc 32; a first air inlet 313 is arranged at the top of the cutting chamber 31, an ice outlet groove 314 is connected to the bottom of the cutting chamber 31, the ice outlet groove 314 is communicated with the ice outlet port 22, a first sealing ring 3141 is arranged between the ice outlet groove 314 and the cutting chamber 31, and a second sealing ring 3142 is arranged between the ice outlet groove 314 and the pressure box 20. By setting the driving disk 33 to be fixedly connected with the cutting disk 32 and respectively placed in the first cutting hole 311 and the second cutting hole 312 opposite to each other in the cutting chamber 31, the driving disk 33 can stably and effectively drive the cutting disk 32 to perform cutting movement, thereby realizing accurate and efficient cutting of the dry ice 21, cutting the dry ice 21 into a shape and size that meets the requirements of subsequent spraying, etc., improving the quality and efficiency of cutting, and ensuring the realization of the core function of the entire dry ice cutting spraying machine. The first air inlet 313 at the top of the cutting chamber 31 is set to introduce the compressed gas in the pressure box 20 into the cutting chamber 31, so that the pressure in the pressure box 20 The compressed gas passes through the ice outlet 22, and takes away the dry ice 21 chips in the ice outlet trough 314 to flow to the ice outlet pipe. The provision of the first sealing ring 3141 and the second sealing ring 3142 greatly improves the reliability of the dry ice 21 transmission process, and effectively prevents the leakage of the dry ice 21 on the transmission path from the cutting chamber 31 to the ice outlet trough 314 and then to the ice outlet 22, ensuring that each piece of cut dry ice 21 can completely enter the ice outlet pipe for the spraying operation, avoiding the problems of insufficient and uneven spraying caused by the leakage of dry ice 21, thereby improving the working stability and reliability of the entire dry ice cutting and spraying machine.

[0054] As a further improvement of the present invention, the cutting module 30 also includes a cutting motor 34, a synchronous belt 35 and a drive shaft 36; the cutting motor 34 is fixedly connected to the frame 10, and the output shaft of the cutting motor 34 is transmission-connected to the drive shaft 36 via the synchronous belt 35, and the drive shaft 36 passes through the pressure box 20 and is fixedly connected to the drive disk 33. By setting the cutting motor 34 to be fixedly connected to the frame 10, it is ensured that the cutting motor 34 can maintain a stable position during operation, and the output shaft of the cutting motor 34 establishes a transmission connection with the drive shaft 36 via the synchronous belt 35. When the cutting motor 34 starts to run, the rotational power of the output shaft of the cutting motor 34 is transmitted to the drive shaft 36 via the synchronous belt 35, so that the drive shaft 36 can rotate accordingly. The drive shaft 36 further penetrates the pressure box 20 and is fixedly connected to the drive disc 33 located in the cutting chamber 31. The rotation of the drive shaft 36 can drive the drive disc 33 to rotate synchronously. Since the drive disc 33 is fixedly connected to the cutting disc 32, the cutting disc 32 is driven to rotate together, thereby realizing the cutting action of the dry ice 21. Through the coordinated cooperation of the cutting motor 34, the synchronous belt 35 and the drive shaft 36, a stable and efficient power transmission system is formed. The cutting motor 34, as a power source, can provide stable rotational power. The synchronous belt 35 can ensure the effective transmission of power while flexibly adjusting the transmission ratio and other parameters as needed, so that the drive shaft 36 can obtain a suitable rotation speed to drive the drive disc 33 and the cutting disc 32 to perform cutting operations. This transmission method can ensure the continuity and stability of the cutting action, and improve the efficiency and quality of cutting the dry ice 21.

[0055] Specifically, a third sealing ring 361 is provided between the drive shaft 36 and the pressure box 20, a sleeve 362 is provided on the drive shaft 36, a bearing 363 is provided between the drive shaft 36 and the sleeve 362, and a fourth sealing ring 364 is provided between the bearing 363 and the drive shaft 36. By providing the third sealing ring 361 between the drive shaft 36 and the pressure box 20, it is prevented that the high-pressure gas and dry ice 21 debris in the pressure box 20 leak out through the gap between the drive shaft 36 and the pressure box 20, and it is also prevented that outside air enters the pressure box 20 to affect the internal pressure environment and the operation of cutting dry ice 21, so as to ensure that the working environment in the pressure box 20 is relatively stable and well sealed. By providing the sleeve 362 on the drive shaft 36, the sleeve 362 provides a certain support and positioning effect for the drive shaft 36, which helps to maintain the stability of the drive shaft 36 during the rotation process, so that the drive The shaft 36 can accurately transmit power. A fourth sealing ring 364 is provided between the bearing 363 and the drive shaft 36 to prevent the lubricating grease in the bearing 363 from leaking out from the gap between the bearing 363 and the drive shaft 36. It also prevents foreign impurities from entering the bearing 363 and affecting its normal operation, ensuring that the bearing 363 can continue to effectively play its function of reducing friction, maintaining a good rotation state of the drive shaft 36, enhancing the sealing performance of the entire cutting module 30, and helping to maintain the normal working environment of the entire dry ice cutting jet machine, and reducing the probability of failures caused by leakage and other problems. The shaft sleeve 362 provides necessary support and positioning for the drive shaft 36, so that the drive shaft 36 can maintain a stable position and correct axial direction during the rotation process, reducing problems such as unstable power transmission and collision and friction with other components caused by factors such as vibration and offset, ensuring the stable operation of the entire cutting module 30, and extending the service life of the equipment.

[0056] As a further improvement of the present invention, the sleeve 362 includes a sealing portion 3621, the pressure box 20 is provided with a sealing groove 23, and the sealing portion 3621 is fixedly connected to the sealing groove 23; the sealing portion 3621 is provided with an annular groove 3622 toward the sealing groove 23, and a fifth sealing ring 3623 is provided inside the annular groove 3622. In some embodiments, the annular groove 3622 can be set as two adjacent ones, and accordingly, the number of the fifth sealing ring 3623 is also two, so as to improve the sealing effect. By setting the shaft sleeve 362 to include a sealing portion 3621, the sealing portion 3621 forms a fixed connection relationship with the sealing groove 23 set on the pressure box 20, so that the shaft sleeve 362 can be firmly installed on the pressure box 20, and an accurate support position is provided for the drive shaft 36, so as to ensure that the drive shaft 36 maintains a stable axial direction during rotation. By providing an annular groove 3622 on the side of the sealing portion 3621 facing the sealing groove 23, the sealing effect is further enhanced. By providing the fifth sealing ring 3623 inside the annular groove 3622, when the shaft sleeve 362 is connected to the pressure box 20 through the sealing portion 3621 and the sealing groove 23, the fifth sealing ring 3623 is squeezed into the annular groove 362. 2 and the sealing groove 23, a tight sealing state is formed, which effectively prevents the high-pressure gas, dry ice 21 fragments and other substances in the pressure box 20 from leaking out through the connection between the shaft sleeve 362 and the pressure box 20, and also prevents the outside air from entering the pressure box 20, further ensuring the sealed environment in the pressure box 20, ensuring that the dry ice cutting and spraying machine performs dry ice 21 cutting and subsequent operations under stable pressure conditions, significantly strengthening the sealing effect of the connection between the shaft sleeve 362 and the pressure box 20, and working together with the third sealing ring 361 to form a more rigorous sealing system, more effectively preventing the leakage of high-pressure gas and dry ice 21 fragments in the pressure box 20, and avoiding the interference of outside air on the environment in the pressure box 20, ensuring that the pressure in the pressure box 20, the state of dry ice 21, etc. remain stable, and providing a more reliable sealing guarantee for the efficient and stable operation of the dry ice cutting and spraying machine.

[0057] As a further improvement of the present invention, the material transfer module 40 includes a material transfer track 41 and a material transfer cylinder 42 arranged in parallel with the material transfer track 41; the material transfer track 41 is arranged at the bottom of the pressure box 20; and the material transfer cylinder 42 is fixedly connected to the cutting chamber 31. By setting the material transfer track 41 to provide guidance for ice transfer, it is ensured that the dry ice 21 can move along a specific direction during the pushing process, and the accuracy and stability of the moving path are maintained. In practical applications, the surface of the material transfer track 41 is usually set to a smooth structure to reduce the friction of the dry ice 21 during the movement process, so that the dry ice 21 can slide or roll smoothly on the track, so as to be efficiently transferred to a position close to the cutting chamber 31. By setting the material transfer cylinder 42 to provide power for pushing the dry ice 21, the dry ice 21 moves along the material transfer track 41 toward the cutting chamber 31, ensuring that the dry ice 21 can fit closely to the cutting disk 32 in the cutting chamber 31, so as to perform effective cutting operations.

[0058] As a further improvement of the present invention, the material moving module 40 also includes a material moving plate 43 and a connecting member 44, the material moving plate 43 abuts against the end of the dry ice 21; the material moving cylinder 42 is provided with a moving member 421, and the moving member 421 is connected to the material moving plate 43 through the connecting member 44. By setting the material transfer plate 43 to contact the end of the dry ice 21, power can be more effectively transmitted to the dry ice 21, making the transfer of the dry ice 21 more direct and efficient, ensuring that the dry ice 21 can continuously and stably move along the material transfer track 41 toward the cutting chamber 31, thereby improving the working efficiency of the entire material transfer module 40, and further accelerating the operating speed of the dry ice cutting jet machine. The moving part 421 provided on the material transfer cylinder 42 is connected to the material transfer plate 43 through the connecting part 44, forming a complete power transmission. When the material transfer cylinder 42 is working, the internal piston of the material transfer cylinder 42 drives the moving part 421 to move, and the moving part 421 transmits power to the material transfer plate 43 through the connecting part 44, so that the material transfer plate 43 can exert a driving force on the dry ice 21, prompting the dry ice 21 to move along the material transfer track 41 toward the cutting chamber 31. Through the coordinated work of the material moving plate 43, the connecting member 44 and the moving member 421, the material moving module 40 can better adapt to dry ice 21 of different shapes, sizes and hardnesses. For larger blocks of dry ice 21, the material moving plate 43 can effectively push the dry ice 21 to move by adjusting the contact area with the dry ice 21; for dry ice 21 with higher hardness, sufficient power can also be transmitted through the connecting member 44 to ensure that the dry ice 21 can be smoothly transferred, thereby improving the versatility and applicability of the dry ice cutting jet machine.

[0059] As a further improvement of the present invention, a cutting blade 321 is radially fixed on the cutting disc 32, and a first air inlet hole 3211 is provided on the cutting blade 321. The reasonable arrangement of the cutting blade 321 ensures efficient cutting of the dry ice 21. The sharp edge of the cutting blade 321 and the radial fixing method on the cutting disc 32 enable the cutting blade 321 to contact and cut the dry ice 21 in a stable and effective manner when the cutting disc 32 rotates, so that the dry ice 21 is quickly and accurately cut into a desired shape and size, thereby improving the efficiency and quality of cutting and meeting the basic requirements of the dry ice cutting jet machine for processing dry ice 21. By setting the first air inlet hole 3211 on the cutting blade 321, when the entire cutting module 30 is working, the gas in the pressure box 20 will enter the cutting chamber 31 through the first air inlet hole 3211, so that the dry ice 21 particles can be more smoothly sprayed through subsequent channels such as the ice outlet trough 314 after being cut, avoiding problems such as uneven and unsmooth spraying caused by accumulation or adhesion of dry ice 21 particles, thereby optimizing the entire process of dry ice 21 spraying, improving the working efficiency and spraying effect of the dry ice cutting sprayer, and at the same time, by introducing gas, the heat generated in the cutting process can be taken away in time, which has a good cooling effect on both the cutting disk 32 and the cutting blade 321, preventing problems such as deformation and damage of components due to overheating, and extending the service life of the cutting disk 32 and the cutting blade 321.

[0060] As a further improvement of the present invention, see Figure 5, the pressure box 20 is provided with a transfer air hole 24 and a transfer plate 25; the transfer air hole 24 includes a pressure box air inlet 241, a pressure box air outlet 242, a material transfer cylinder 42 air inlet 243, a material transfer cylinder 42 air outlet 244 and a detection air hole 245, the material transfer cylinder 42 air inlet 243 and the material transfer cylinder 42 air outlet 244 are respectively connected to the material transfer cylinder 42, the detection air hole 245 is connected to the barometer 101, and the air tightness of the pressure box 20 is ensured by the transfer air hole 24 provided on the pressure box 20, the material transfer cylinder 42 air inlet 243 and the material transfer cylinder 42 air outlet 244 are respectively connected to the material transfer cylinder 42, the material transfer cylinder 42 air inlet 243 is responsible for conveying gas into the material transfer cylinder 42, providing a power source for the movement of the piston in the material transfer cylinder 42, so that the active The plug can reciprocate under the action of air pressure, and then drive the material transfer plate 43 to push the dry ice 21 to move through the connecting piece 44, etc. The air outlet 244 of the material transfer cylinder 42 is used to discharge the waste gas or excess gas generated by the material transfer cylinder 42 during operation to maintain the normal circulation and pressure balance of the gas in the cylinder. The detection hole 245 is connected to the barometer 101. Through the detection hole 245, the barometer 101 can monitor the air pressure in the pressure box 20 in real time. When the air pressure in the pressure box 20 changes, the barometer 101 will display the accurate air pressure value accordingly, providing the operator with intuitive information on the air pressure status in the pressure box 20, so as to adjust the relevant equipment parameters or take corresponding measures in time to ensure that the air pressure in the pressure box 20 is in a suitable working range and ensure the normal operation of the entire dry ice cutting jet machine. The operator can accurately understand the air pressure state in the pressure box 20 according to the real-time air pressure value displayed by the barometer 101, and then accurately control the gas in and out of the pressure box air inlet 241, the pressure box air outlet 242, etc. When the air pressure is too high, the air pressure can be reduced by adjusting the exhaust volume of the pressure box air outlet 242; when the air pressure is too low, the air intake volume of the pressure box air inlet 241 can be appropriately increased to ensure that the air pressure in the pressure box 20 is always maintained within a reasonable range suitable for operations such as cutting and moving dry ice 21, thereby improving the stability and reliability of the entire equipment operation.

[0061] Furthermore, the adapter plate 25 is provided with wiring holes 251. The adapter plate 25 is arranged on the pressure box 20 to provide a platform for electrical connection. The adapter plate 25 is provided with wiring holes 251, which can be used to connect various electrical devices or lines, such as the power line for connecting the cutting motor 34, the control line for controlling the operation of the cutting module 30 and the material transfer module 40, etc. Through these wiring holes 251, the power supply and control signal transmission of the cutting motor 34 and the material transfer cylinder 42 in the pressure box 20 can be realized, ensuring that each device can work normally according to the predetermined procedures and requirements. The setting of the adapter air hole 24 and the adapter plate 25 further enhances the equipment integration of the pressure box 20 and even the entire dry ice cutting jet machine. They integrate multiple functions such as gas circulation, air pressure monitoring, and electrical connection on the pressure box 20, making the overall structure of the equipment more compact and reasonable. At the same time, this integration also provides convenience for the scalability of the equipment.

[0062] As a further improvement of the present invention, the pressure box 20 comprises a box body 201 and a cover plate 202 detachably connected to the box body 201, a sixth sealing ring 203 is arranged between the box body 201 and the cover plate 202, and an open end of the box body 201 extends outward to form a fixed ear portion 2011, and the fixed ear portion 2011 is fixedly connected to the rack 10. By arranging the pressure box 20 to be composed of the box body 201 and the cover plate 202 detachably connected thereto, maintenance, inspection and filling of dry ice 21 inside the pressure box 20 are facilitated. By arranging the sixth sealing ring 203 between the box body 201 and the cover plate 202, the high-pressure gas, dry ice 21 fragments, etc. in the pressure box 20 are effectively prevented from leaking out from the connection between the box body 201 and the cover plate 202, and the outside air is also prevented from entering the pressure box 20, ensuring that a relatively stable pressure environment and working environment are maintained inside the pressure box 20. By setting the opening end of the box body 201 to extend outward to form a fixed ear 2011, these fixed ears 2011 are fixedly connected to the frame 10 by bolts, so that the pressure box 20 can be firmly installed on the frame 10, providing a stable support base for the cutting module 30, the material transfer module 40, etc. in the pressure box 20, ensuring that during the operation of the dry ice cutting jet machine, the pressure box 20 will not be displaced or loosened due to factors such as vibration and external force impact, thereby ensuring the stability of the entire equipment. The detachable connection between the box body 201 and the cover plate 202 can be achieved through a quick-release clamp 204. When it is necessary to inspect, clean, repair parts or load dry ice 21 inside the pressure box 20, the relevant operations can be easily performed by simply removing the cover plate 202, without large-scale disassembly of the entire pressure box 20 or the equipment, which greatly saves time and energy and improves the maintainability and use efficiency of the equipment.

[0063] As a further improvement of the present invention, a gas pressure protection part 2021 is provided on the cover plate 202. When the internal gas pressure of the pressure box 20 is too high, the pressure box 20 is exhausted through the gas pressure protection part 2021 to ensure that the gas pressure state in the pressure box 20 is stable. By exhausting the excessive gas pressure in time, a series of problems that may be caused by excessive gas pressure are avoided, such as the sealing structure of the pressure box 20 being damaged due to excessive pressure, affecting the normal operation of internal components such as cutting and transfer of dry ice 21, etc. A stable gas pressure environment is conducive to the stable operation of dry ice 21 during cutting, spraying and other processes, and improves the operating efficiency and reliability of the entire equipment. The gas pressure protection part 2021 can take timely measures to exhaust gas when the gas pressure rises abnormally, effectively preventing the equipment from being damaged due to excessive gas pressure, protecting the integrity and safety of the equipment, reducing equipment failures and safety risks, and extending the service life of the equipment.
