Description

Technical Field

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

[0002] A snowflake cleaning machine is a device that uses snowflake-shaped dry ice particles for cleaning. This type of machine sprays dry ice (solid carbon dioxide) particles onto the surface of the object to be cleaned to achieve a cleaning effect. When the dry ice particles collide with the target surface, they rapidly sublimate (directly changing from a solid to a gaseous state), generating physical and thermal shock to remove dirt, grease, coatings, and other contaminants.

[0003] Currently, snow cleaning machines directly spray dry ice particles onto the surface to be cleaned to remove dirt, grease, coatings, and other contaminants. However, the spray position and height of the snow cleaning machine nozzle cannot be adjusted to the object being cleaned, which affects the cleaning effect and efficiency. Utility Model Content In response to the shortcomings of the existing production technology, the applicant provides a snowflake cleaning machine. By improving the structure of the snowflake cleaning machine, the spray position and spray height of the snowflake cleaning machine nozzle can be adjusted to improve the cleaning effect and cleaning efficiency of objects.

[0004] The technical solution adopted in this utility model is as follows: A snowflake cleaning machine includes: a dry ice manufacturing mechanism, a nozzle, and a drive mechanism. The dry ice manufacturing mechanism is used to pressurize liquid carbon dioxide to convert it into gaseous carbon dioxide and solid carbon dioxide. The dry ice manufacturing mechanism is also used to compress air to form compressed air. The nozzle is connected to the outlet end of the dry ice manufacturing mechanism through a connecting pipe, so that the nozzle sprays a mixture of gaseous carbon dioxide, solid carbon dioxide, and compressed air in a snowflake-like form and acts on the surface of an object to perform a cleaning operation. The two output ends of the drive mechanism are respectively connected to the nozzle and the connecting pipe. The drive mechanism is used to drive the nozzle to move in the XOY plane to adjust the spray position of the nozzle relative to the object to be cleaned. The drive mechanism is also used to drive the nozzle to move in the Z-axis direction to adjust the spray height of the nozzle relative to the object to be cleaned.

[0005] Therefore, by adjusting the spray position and spray height of the nozzle relative to the object to be cleaned through the drive mechanism, compared with the existing method of keeping the nozzle fixed, this method has a simple structure and is easy to operate. By adjusting the spray position and spray height of the nozzle relative to the object to be cleaned, the nozzle can adapt to the cleaning operation of objects of different sizes, thereby improving the cleaning effect and cleaning efficiency.

[0006] As a further improvement to the above technical solution: the driving mechanism includes a first driving part, a second driving part, a fixing part, and a third driving part. The driving end of the first driving part is connected to the second driving part. One end of the fixing part and the third driving part are both connected to the driving end of the second driving part. The other end of the fixing part is connected to the connecting pipe. The driving end of the third driving part is connected to the nozzle. The first driving part is used to drive the nozzle to move along the X-axis direction. The second driving part is used to drive the nozzle to move along the Y-axis direction to adjust the spray position of the nozzle relative to the object to be cleaned. The third driving part is used to drive the nozzle to move along the Z-axis direction to adjust the spray height of the nozzle relative to the object to be cleaned.

[0007] As a further improvement to the above technical solution: the fixing part includes a fixing rod and a first fixing component, one end of the fixing rod is connected to the driving end of the second driving part, the other end of the fixing rod is connected to the first fixing component, and the first fixing component is connected to the connecting pipe.

[0008] As a further improvement to the above technical solution: the first fixing component includes a fixing block, two clamping blocks, and two bolts. The other end of the fixing rod is connected to the fixing block. The clamping blocks and the bolts are located on the side of the fixing block away from the fixing rod, and the clamping blocks are slidably connected to the fixing block. The two clamping blocks are connected by the two bolts, and the two clamping blocks are used together to install the connecting pipe. Thus, the bolts enable a detachable connection between the two fixing blocks, facilitating the installation and removal of the connecting pipe relative to the first fixing component. Furthermore, the installation position of the connecting pipe can be adjusted.

[0009] As a further improvement to the above technical solution: the third driving part includes: a first driving member and a second fixing component, the first driving member is connected to the driving end of the second driving part, the telescopic end of the first driving member is connected to the second fixing component, and the nozzle is mounted on the second fixing component.

[0010] As a further improvement to the above technical solution, the second fixing component has the same structure as the first fixing component. Therefore, the second fixing component facilitates the installation and removal of the nozzle.

[0011] As a further improvement to the above technical solution: the dry ice manufacturing mechanism includes a first booster pump and a second booster pump, the outlet ends of the first booster pump and the second booster pump being connected to the connecting pipe; the first booster pump is used to pressurize liquid carbon dioxide to convert it into gaseous carbon dioxide and solid carbon dioxide, and the second booster pump is used to compress air to form compressed air, so that the nozzle sprays out a mixture of gaseous carbon dioxide, solid carbon dioxide, and compressed air in a snowflake-like pattern. Thus, mixing compressed air into gaseous and solid carbon dioxide allows them to be sprayed out in a snowflake-like pattern, and also increases the interaction force between the gaseous and solid carbon dioxide, thereby further improving the cleaning effect and efficiency.

[0012] As a further improvement to the above technical solution, the nozzle has multiple spray holes.

[0013] As a further improvement to the above technical solution, it also includes: a housing, wherein the first booster pump and the second booster pump are both located inside the housing, and the inlet end of the first booster pump and the inlet end of the second booster pump both penetrate the housing, and the nozzle, the connecting pipe and the drive mechanism are all located outside the housing.

[0014] As a further improvement to the above technical solution, it also includes: a support plate, which is installed on the side wall of the housing, and the drive mechanism is connected to the housing.

[0015] The beneficial effects of this utility model are as follows: By adjusting the spray position and height of the nozzle relative to the object to be cleaned through a drive mechanism, this method is simpler in structure and easier to operate compared to the existing method where the nozzle remains stationary. By adjusting the spray position and height of the nozzle relative to the object to be cleaned, the nozzle can adapt to the cleaning operation of objects of different sizes, thereby improving the cleaning effect and cleaning efficiency.

[0016] This utility model also has the following advantages: 1.

[0020] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0021] like Figures 1 to 9The diagram shows the preferred embodiment of this utility model. The snowflake cleaning machine of this embodiment includes: a dry ice manufacturing mechanism 1, a nozzle 2, and a drive mechanism 4. The dry ice manufacturing mechanism 1 is used to pressurize liquid carbon dioxide to convert it into gaseous and solid carbon dioxide. The dry ice manufacturing mechanism 1 is also used to compress air to form compressed air. The nozzle 2 is connected to the outlet end of the dry ice manufacturing mechanism 1 through a connecting pipe 3, so that the nozzle 2 sprays a mixture of gaseous carbon dioxide, solid carbon dioxide, and compressed air in a snowflake-like shape, which acts on the surface of the object to perform cleaning operations. The two output ends of the drive mechanism 4 are respectively connected to the nozzle 2 and the connecting pipe 3. The drive mechanism 4 is used to drive the nozzle 2 to move in the XOY plane to adjust the spray position of the nozzle 2 relative to the object to be cleaned. The drive mechanism 4 is also used to drive the nozzle 2 to move in the Z-axis direction to adjust the spray height of the nozzle 2 relative to the object to be cleaned. Therefore, by adjusting the spray position and spray height of the nozzle 2 relative to the object to be cleaned through the drive mechanism 4, compared with the existing method of keeping the nozzle 2 fixed, this method has a simple structure and is easy to operate. By adjusting the spray position and spray height of the nozzle 2 relative to the object to be cleaned, the nozzle 2 can adapt to the cleaning operation of objects of different sizes, thereby improving the cleaning effect and cleaning efficiency.

[0022] In other words, by adjusting the spray position of nozzle 2 relative to the object to be cleaned, full coverage of the surface of the object can be achieved. This adapts to cleaning operations of objects of different sizes, thereby improving the cleaning effect and efficiency. By adjusting the spray height of nozzle 2 relative to the object to be cleaned, the spray height of nozzle 2 is always kept at the optimal spray height (i.e., the distance between nozzle 2 and the object to be cleaned remains constant). This ensures that the effect of pressurized gaseous carbon dioxide will not change due to changes in the height of the object to be cleaned. At the same time, because the spray height of nozzle 2 is always at the optimal spray height, collisions between nozzle 2 and the object to be cleaned can be avoided, preventing damage to nozzle 2. This allows nozzle 2 to adapt to cleaning operations of objects of different sizes, thereby improving the cleaning effect and efficiency, and also extending the service life of nozzle 2.

[0023] In this embodiment, the drive mechanism 4 includes: a first drive unit 5, a second drive unit 6, a fixing unit 7, and a third drive unit 8. The drive end of the first drive unit 5 is connected to the second drive unit 6. One end of the fixing unit 7 and the third drive unit 8 are both connected to the drive end of the second drive unit 6. The other end of the fixing unit 7 is connected to the connecting pipe 3. The drive end of the third drive unit 8 is connected to the nozzle 2. The first drive unit 5 is used to drive the nozzle 2 to move along the X-axis direction. The second drive unit 6 is used to drive the nozzle 2 to move along the Y-axis direction to adjust the spray position of the nozzle 2 relative to the object to be cleaned. The third drive unit 8 is used to drive the nozzle 2 to move along the Z-axis direction to adjust the spray height of the nozzle 2 relative to the object to be cleaned. The fixing unit 7 includes: a fixing rod 701 and a first fixing component 702. One end of the fixing rod 701 is connected to the drive end of the second drive unit 6. The other end of the fixing rod 701 is connected to the first fixing component 702. One end of the fixing rod 701 is connected to the first fixing component 702, which is connected to the connecting pipe 3. The first fixing component 702 includes a fixing block 703, two clamping blocks 704, and two bolts 705. The other end of the fixing rod 701 is connected to the fixing block 703. The clamping blocks 704 and bolts 705 are located on the side of the fixing block 703 away from the fixing rod 701, and the clamping blocks 704 are slidably connected to the fixing block 703. The two clamping blocks 704 are connected by two bolts 705, and the two clamping blocks 704 are used together to install the connecting pipe 3. The third driving part 8 includes a first driving member 801 and a second fixing component 802. The first driving member 801 is connected to the driving end of the second driving part 6, and the telescopic end of the first driving member 801 is connected to the second fixing component 802. The nozzle 2 is installed on the second fixing component 802. The second fixing component 802 has the same structure as the first fixing component 702. Thus, the two fixing blocks 703 can be detachably connected by bolts 705, which facilitates the installation and removal of the connecting pipe 3 relative to the first fixing component 702. In addition, the installation position of the connecting pipe 3 can be adjusted. The second fixing component facilitates the installation and removal of the nozzle 2.

[0024] Specifically, in the initial state, the connecting pipe 3 is placed between two clamping blocks 704 and fixed by two mutually abutting clamping blocks 704 (the two clamping blocks 704 are fixed by bolts 705); since the clamping blocks 704 can slide relative to the fixed block 703, when it is necessary to disassemble the connecting pipe 3, the bolts 705 are rotated and loosened, and the two clamping blocks 704 are moved away from each other, so as to disassemble the connecting pipe 3.

[0025] Specifically, the first driving unit 5 includes: a second driving member 501, a first lead screw 502, and a first slider 503. The second driving member 501 is connected to the support plate 10. One end of the first lead screw 502 is rotatably connected to the support plate 10, and the other end of the first lead screw 502 is connected to the driving end of the second driving member 501. The first slider 503 passes through the first lead screw 502 and is threadedly connected to the first lead screw 502.

[0026] Specifically, the second drive unit 6 includes: a third drive member 601, a second lead screw 602, and two second sliders 603. The third drive member 601 is connected to the first slider 503. One end of the second lead screw 602 is rotatably connected to the first slider 503, and the other end of the first lead screw 502 is connected to the drive end of the third drive member 601. The second slider 603 passes through the second lead screw 602 and is threadedly connected to the second lead screw 602. One end of the fixing rod 701 is connected to one of the second sliders 603, and the first drive member 801 is connected to the other second slider 603.

[0027] For example, the first driving component 801 is a cylinder, the second driving component 501 is a motor, and the third driving component 601 is a motor.

[0028] In this embodiment, the dry ice manufacturing mechanism 1 includes a first booster pump 101 and a second booster pump 102. The outlet ends of both the first booster pump 101 and the second booster pump 102 are connected to the connecting pipe 3. The first booster pump 101 is used to pressurize liquid carbon dioxide to convert it into gaseous carbon dioxide and solid carbon dioxide. The second booster pump 102 is used to compress air to form compressed air, so that the nozzle 2 sprays out a mixture of gaseous carbon dioxide, solid carbon dioxide, and compressed air in a snowflake-like pattern. Thus, by mixing compressed air into gaseous carbon dioxide and solid carbon dioxide, the gaseous carbon dioxide and solid carbon dioxide can be sprayed out in a snowflake-like pattern. At the same time, it can also increase the interaction force between gaseous carbon dioxide and solid carbon dioxide, thereby further improving the cleaning effect and cleaning efficiency of the object.

[0029] It should be noted that the snowflake-like shape refers to the fact that after gaseous carbon dioxide and solid carbon dioxide are mixed with compressed air to form a mixture, the mixture can be quickly ejected through nozzle 2, and the high-speed ejected mixture appears as a snowflake (i.e., the appearance of a snowflake).

[0030] In this embodiment, the nozzle 2 has multiple spray holes 201. Specifically, the arrangement of the multiple spray holes 201 includes, but is not limited to, two rows and three columns (e.g., Figure 7 As shown), two rows and four columns (as shown) Figure 8 As shown), three rows and two columns (as shown) Figure 9 (As shown).

[0031] In this embodiment, the system also includes: a housing 9 and a support plate 10. The first booster pump 101 and the second booster pump 102 are both located inside the housing 9, and the inlet end of the first booster pump 101 and the inlet end of the second booster pump 102 both penetrate the housing 9. The nozzle 2, the connecting pipe 3 and the drive mechanism 4 are all located outside the housing 9. The support plate 10 is installed on the side wall of the housing 9, and the drive mechanism 4 is connected to the housing 9.

[0032] The cleaning process of this utility model is as follows: First, the object to be cleaned is placed on the operating table (not shown in the figure) and fixed. Next, the spray height of the nozzle 2 is adjusted according to the height of the object to be cleaned by the second drive unit 6. Finally, the first booster pump 101 and the second booster pump 102 are started. The first booster pump 101 converts liquid carbon dioxide into particulate gaseous carbon dioxide. After being pressurized by the second booster pump 102, the pressurized particulate gaseous carbon dioxide sprayed at high speed by the nozzle 2 acts on the surface of the object to be cleaned in a snowflake-like form. At the same time, the spray position of the nozzle 2 is adjusted by the first drive unit 5 and the second drive unit 6, so that the surface of the object to be cleaned can be cleaned in all directions.

[0033] In summary, this utility model uses a drive mechanism 4 to adjust the spray position and spray height of the nozzle 2 relative to the object to be cleaned. Compared with the existing method where the nozzle 2 is fixed and does not move, this method has a simple structure and is easy to operate. By adjusting the spray position and spray height of the nozzle 2 relative to the object to be cleaned, the nozzle 2 can adapt to the cleaning operation of objects of different sizes, thereby improving the cleaning effect and cleaning efficiency.
