[0002] Dry ice cleaning machine is a type of cleaning machine. Dry ice cleaning has been developing rapidly around the world. The cleaning system uses high-pressure air to spray dry ice pellets from the dry ice cleaning machine onto the work surface that needs to be cleaned, and uses the physical reflection of temperature difference to make different substances separate at different shrinkage speeds. When the dry ice pellets at -78 degrees Celsius come into contact with the dirt surface, they will produce a brittle explosion phenomenon, causing the dirt to shrink and loosen. Then the dry ice pellets will instantly vaporize and expand 800 times.

[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, in the first embodiment of the discharge mechanism of the dry ice cleaning machine of the present invention, the discharge mechanism 10 includes a discharge seat 11, a discharge rotor 12 rotatably disposed on the discharge seat 11, a hopper cover 13 covered on the discharge rotor 12, and a driving motor 14 driving the discharge rotor 12 to rotate.

[0025] A silo 15 is provided in the discharge seat 11, an air outlet 16 connected to the silo 15 is provided on a first side of the discharge seat 11, an air inlet 17 connected to the silo 15 is provided on a second side of the discharge seat 11, a feed port 18 is provided on the hopper cover 13, the discharge rotor 12 is located directly below the feed port 18, a plurality of material troughs 19 are provided on the discharge rotor 12, and the plurality of material troughs 19 are used to transport the material in the hopper cover 13 to the silo 15 during the rotation of the discharge rotor 12.

[0026] In this embodiment, during the dry ice cleaning process, the dry ice particles need to be ground first, and the large particles of dry ice are processed and ground to obtain fine particles for cleaning needs. Then the discharge mechanism 10 discharges them for cleaning. In actual operation, small particles of dry ice can also be directly added to the dry ice cleaning machine to omit the grinding process. In other words, the various embodiments of this patent do not limit the type of dry ice consumables, and the discharge mechanisms that can be applied to this patent are all within the scope of protection of this patent.

[0027] When the discharging mechanism 10 of the utility model is used, dry ice (such as snowflake dry ice) particles fall onto the hopper cover 13 of the discharging mechanism 10. The dry ice particles in the hopper cover 13 eventually enter the material trough 19 of the discharging rotor 12 under the action of their own gravity. During the rotation of the discharging rotor 12, the discharging rotor 12 brings the dry ice particles in the material trough 19 into the silo 15, and finally the high-pressure gas blown in from the air inlet 17 blows the dry ice particles in the silo 15 out of the air outlet 16. The dry ice particles blown out from the air outlet 16 can be used for dry ice cleaning. In the present application, the discharging mechanism can deliver the dry ice particles into the silo 15 evenly and at a uniform speed, and blow them out evenly by the high-pressure gas, achieving a better cleaning effect.

[0028] Furthermore, a partition 20 is provided in the silo 15 for dividing the silo 15 into a first chamber 21 and a second chamber 22 . The first chamber 21 is communicated with the air outlet 16 , and the second chamber 22 is communicated with the air inlet 17 .

[0029] When the trough 19 on the discharging rotor 12 rotates to the partition 20 position, the first chamber 21 and the second chamber 22 are connected through the trough 19, and the high-pressure gas entering from the air inlet 17 can blow the dry ice particles in the trough 19 into the first chamber 21 connected to the air outlet 16, thereby realizing air circulation and discharging continuously.

[0030] In this embodiment, the discharging mechanism 10 further includes an air outlet pipe connected to the air outlet 16 and an air inlet pipe connected to the air inlet 17 , and the air inlet pipe is used to communicate with an air compressor.

[0031] The air inlet pipe is used to be connected and communicated with the air compressor, and the air outlet pipe is a dry ice particle discharge pipe for cleaning.

[0032] Furthermore, the discharge seat 11 includes a base 23 and an adapter seat 24 installed on the base 23. The silo 15 is arranged on the base 23. The adapter seat 24 is provided with an arc groove 25 for accommodating the discharge rotor 12 to rotate. The bottom of the arc groove 25 is provided with a connecting port 26 connected to the silo 15. The connecting port 26 is provided with a partition plate 27 corresponding to and parallel to the partition 20 and dividing the connecting port 26 into a first channel 28 and a second channel 29. The partition 20 is in contact with the partition plate 27. The first channel 28 is connected to the first chamber 21, and the second channel 29 is connected to the second chamber 22.

[0033] In this embodiment, the discharge seat 11 also includes a movable seat 41 that can be moved up and down in the silo 15 of the base 23. The partition 20, the first chamber 21 and the second chamber 22 are all arranged on the movable seat 41. The adapter seat 24 is fixedly connected to the movable seat 41 through the stud 31; the adapter seat 24 is provided with a through hole for the stud 31 to pass through, and the movable seat 41 is provided with a threaded hole for the stud 31 to be inserted and screwed.

[0034] During the process of the discharging rotor 12 rotating and discharging, the discharging rotor 12 brings the dry ice from the material trough 19 into the material bin 15. At this time, the adapter seat 24 does not form a sealed contact with the lower wall of the discharging rotor 12. When the high-pressure gas is not introduced into the air inlet 17, there is a gap between the movable seat 41 and the adapter seat 24 and the discharging rotor 12. After the high-pressure gas is introduced into the air inlet 17, the high-pressure gas pushes the movable seat 41 and the adapter seat 24 to move upward at the same time, and the movable seat 41 moves upward in the base 23, and the base 23 can play a role in limiting the moving direction of the movable seat 41. The movable seat 41 and the adapter seat 24 move upward and form a sealed contact with the lower wall of the discharging rotor 12. At this time, the introduced gas can be prevented from leaking from the gap between the adapter seat 24 and the discharging rotor 12, forming a sealing effect, so that other gases entering from the air inlet 17 can only be discharged from the air outlet 16 after passing through the material trough 19, achieving uniform discharging and effectively improving the dry ice cleaning effect.

[0035] In this embodiment, the adapter seat 24 and the movable seat 41 are two separate bodies connected by the stud 31. In other embodiments, the adapter seat 24 and the movable seat 41 can also be an integral piece.

[0036] In another embodiment, the hopper cover 13 can also be fixedly connected with the adapter seat 24 and the movable seat 41, or the hopper cover 13, the adapter seat 24 and the movable seat 41 are integrally formed, so that the hopper cover 13, the adapter seat 24 and the movable seat 41 are an integral part, and the hopper cover 13 and the adapter seat 24 can respectively form a seal on the upper and lower sides of the discharge rotor 12. Specifically, the hopper cover 13, the adapter seat 24 and the movable seat 41 have an opening on one side and are closed on the other side. The side with the opening faces the air inlet 17. When the air inlet 17 is not fed with high-pressure gas, there is a gap on one side between the movable seat 41 and the adapter seat 24 and the discharge rotor 12. After high-pressure gas is introduced into the air inlet 17, the bottom of the integral seal is squeezed by the high-pressure gas and deformed, the opening is reduced, and the integral seal is tightly attached to the outer wall of the discharging rotor 12 to form a seal. Others entering from the air inlet 17 can only pass through the material trough 19 and then be discharged from the air outlet 16, thereby achieving uniform discharge and effectively improving the dry ice cleaning effect.

[0037] In another embodiment, in order to form a better seal between the adapter seat 24 and the discharging rotor 12 , the adapter seat 24 is connected to the base 23 via a stud 31 , and a compressible gasket 30 is provided at the top end of the stud 31 .

[0038] The adapter seat 24 is provided with a through hole for the stud 31 to pass through, and the base 23 is provided with a threaded hole for the stud 31 to be inserted and threaded.

[0039] After high-pressure air is introduced into the air inlet 17, the high-pressure air pushes the adapter 24 upward, the compressible gasket 30 is squeezed, and the adapter 24 moves slightly toward the discharge rotor 12, so that the adapter 24 abuts against the discharge rotor 12 to form a seal. The airflow passes through the air inlet 17, the second chamber 22, the second channel 29, the trough 19, the first channel 28, the first chamber 21, and finally is discharged through the air outlet 16. During the airflow process, the snowflake-shaped dry ice particles in the trough 19 are brought into the first chamber 21 and blown out from the air outlet 16.

[0040] During the rotation of the discharging rotor 12 , the dry ice particles in the trough 19 rotate along with the discharging rotor 12 and are finally connected to the silo 15 through the connecting port 26 , thereby realizing the uniform speed transportation of the dry ice particles.

[0041] In order to better support the discharging rotor 12, the discharging mechanism 10 also includes a first support plate 32 fixedly installed on the first end of the base 23, and a second support plate 33 fixedly installed on the second end of the base 23. The first support plate 32 is provided with a first rotating hole 34 for the discharging rotor 12 to rotate through and support the discharging rotor 12. The second support plate 33 is provided with a second rotating hole 35 for the discharging rotor 12 to rotate through and support the discharging rotor 12.

[0042] In this embodiment, the first support plate 32 is close to the first end of the discharging rotor 12, and the second support plate 33 is close to the second end of the discharging rotor 12. The discharging rotor 12 passes through the first rotation hole 34 and passes through the second rotation hole 35. The first rotation hole 34 and the second rotation hole 35 are used to support the discharging rotor 12. The first support plate 32 and the second support plate 33 are detachably fixedly connected to the base 23 by bolts or screws.

[0043] Specifically, the discharging mechanism 10 also includes a bottom plate 36 fixedly mounted under the base 23 for fixing the base 23, and a fixing seat 37 vertically fixed on the bottom plate 36 for fixing the driving motor 14. The first support plate 32 is perpendicular to the bottom plate 36 and fixedly connected to the base 23, and the second support plate 33 is perpendicular to the bottom plate 36 and fixedly connected to the base 23.

[0044] To facilitate quick assembly of the discharging rotor 12 and the output shaft of the driving motor 14, a first clamping seat 39 for rotating the output shaft is provided on the output shaft of the driving motor 14, and a second clamping seat 40 which can be clamped with the first clamping seat 39 and rotate with the first clamping seat 39 is provided at the first end of the discharging rotor 12.

[0045] Furthermore, to prevent the discharging rotor 12 from escaping from the second rotating hole 35 , a baffle 38 is provided on the outer side of the second support plate 33 at the position of the second rotating hole 35 to block the second end of the discharging rotor 12 , and the baffle 38 is fixedly connected to the second support plate 33 .

[0046] When assembling the discharging rotor 12, the first clamping seat 39 is fixed to the output shaft of the driving motor 14, and then the protruding portion of the first clamping seat 39 is aligned with the concave portion of the second clamping seat 40 and inserted, so that the first clamping seat 39 and the second clamping seat 40 are mutually clamped and connected. When the output shaft of the driving motor 14 rotates, the output shaft drives the first clamping seat 39 and the second clamping seat 40 to rotate and realizes the driving of the discharging rotor 12 to rotate.

[0047] To prevent the discharging rotor 12 from blocking the first chamber 21 and the second chamber 22 , the plurality of material grooves 19 are staggered on the surface of the discharging rotor 12 , and the transverse center lines of two adjacent material grooves 19 along the length direction of the discharging rotor 12 are not on the same straight line.

[0048] Since the plurality of material troughs 19 are arranged in a staggered manner, no matter to which angle the discharging rotor 12 rotates, there is a material trough 19 connecting the first chamber 21 and the second chamber 22 , thereby forming an air circulation channel.

[0049] It should be noted that, in the present embodiment, the trough 19 of the discharging rotor 12 is provided with a certain slope or curvature to guide the high-pressure gas, so as to facilitate the high-pressure gas to carry out the fine dry ice particles.

[0050] In addition, in the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", "stacked" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
