Description

Technical Field

[0001] The utility model relates to the field of dry ice cleaning, and more specifically, to dry ice cleaning equipment and a system. Background Art

[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. The product's strong peeling force will quickly and thoroughly remove the dirt from the surface of the object, thereby achieving a fast, efficient, safe and energy-saving cleaning effect.

[0003] Existing dry ice cleaning machines require the ground snowflake-shaped dry ice particles to be transported into the hopper and then ejected by the discharging mechanism for cleaning. However, the snowflake-shaped dry ice particles delivered in the early stage need to be discarded due to problems such as particle size and cleanliness, and existing cleaning equipment often requires manual adjustment to discharge the snowflake-shaped dry ice particles delivered in the early stage, which causes certain inconvenience in cleaning and affects the cleaning efficiency.

[0028] 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.

[0029] like Figure 1-2 As shown, in the first embodiment of the multi-station dry ice cleaning equipment of the utility model, the cleaning equipment 10 includes a mounting frame 20, at least one group of guide slide components 30 fixedly mounted on the mounting frame 20, at least one hopper 63 slidably arranged on the at least one group of guide slide components 30, at least one driving component 50 for pushing the hopper 63 to move along the guide slide component 30, a first discharge port 60 and a second discharge port 61 arranged below each hopper 63, a recovery trough 62 arranged below the first discharge port 60, and a discharge mechanism 70 arranged below the second discharge port 61.

[0030] The discharge mechanism 70 is provided with an air inlet 77 and an air outlet 76 . The driving assembly 50 is used to drive the hopper 63 to move along the guide slide assembly 30 and switch between the first discharge port 60 and the second discharge port 61 .

[0031] It can be understood that the mounting frame 20 can be a frame-type mounting frame 20 or a shell-type mounting frame 20.

[0032] The at least one group of guide slide components 30 , the at least one hopper 63 and the at least one driving component 50 correspond one to one, and one driving component 50 is used to drive one hopper 63 to move on one guide slide component 30 .

[0033] When using the multi-station dry ice cleaning device 10 of the utility model, the snowflake-shaped dry ice particles transported by the external delivery pipe can be input into the hopper 63. In the initial stage of transportation, the driving assembly 50 pushes the hopper 63 to move along the guide slide assembly 30 to the position of the first discharge port 60. At this time, the snowflake-shaped dry ice particles fed into the hopper 63 flow into the recovery tank 62 located below the first discharge port 60 through the hopper 63, so as to discharge the initial snowflake-shaped dry ice particles. Thereafter, the driving assembly 50 can be controlled to drive the hopper 63 to move along the guide slide assembly 30 to the position of the second discharge port 61. At this time, the snowflake-shaped dry ice particles fed into the hopper 63 flow into the discharge mechanism 70 through the hopper 63, and finally the high-pressure gas entering the air inlet 77 blows the snowflake-shaped dry ice particles out of the air outlet 76 to form a cleaning effect. After the cleaning is completed, the hopper 63 is moved again to the top of the first discharge port 60, and the snowflake-shaped dry ice particles at the tail section are discharged into the recovery tank 62 for recycling. Furthermore, in the present application, by providing at least one set of guide slide components 30, at least one hopper 63 and at least one drive component 50, a multi-station cleaning device is formed, which can simultaneously perform one-to-one, many-to-one, or many-to-many multi-station dry ice cleaning to improve cleaning efficiency.

[0034] Specifically, Figure 2 As shown, the guide slide assembly 30 includes a first guide slide rod 31 fixedly mounted on the mounting frame 20, a second guide slide rod 32 fixedly mounted on the mounting frame 20 and parallel to the first guide slide rod 31, and a sliding frame 33 slidably arranged on the first guide slide rod 31 and the second guide slide rod 32, and the hopper 63 is fixedly connected to the sliding frame 33.

[0035] Furthermore, the sliding frame 33 includes a first sliding sleeve 34 and a second sliding sleeve 35 slidably arranged on the first guide sliding rod 31, a third sliding sleeve 36 and a fourth sliding sleeve 37 slidably arranged on the second guide sliding rod 32, a first connecting rod 38 fixed between the first sliding sleeve 34 and the third sliding sleeve 36, a second connecting rod 39 fixed between the second sliding sleeve 35 and the fourth sliding sleeve 37, a first connecting plate fixed at the first end of the first connecting rod 38 and the first end of the second connecting rod 39, and a second connecting plate 40 fixed at the second end of the first connecting rod 38 and the second end of the second connecting rod 39. The first side of the hopper 63 is provided with a first connecting member fixedly connected to the first connecting plate, and the second side of the hopper 63 is provided with a second connecting member 41 fixedly connected to the second connecting plate 40.

[0036] During the sliding process, the first sliding sleeve 34, the second sliding sleeve 35, the third sliding sleeve 36 and the fourth sliding sleeve 37 slide synchronously on the first guide slide rod 31 and the second guide slide rod 32, driving the sliding frame 33 to slide on the first guide slide rod 31 and the second guide slide rod 32, and driving the hopper 63 to slide along the first guide slide rod 31 and the second guide slide rod 32, so as to realize the docking and switching between the bottom end of the hopper 63 and the first discharge port 60 and the second discharge port 61.

[0037] Specifically, the driving assembly 50 is a telescopic cylinder 51 , and the hopper 63 is provided with a connecting seat 53 rotatably connected to the telescopic rod 52 of the telescopic cylinder 51 .

[0038] In this embodiment, the telescopic cylinder 51 is a pneumatic telescopic cylinder 51. In other embodiments, the telescopic cylinder 51 may also be an electric telescopic cylinder 51 or a hydraulic telescopic cylinder 51.

[0039] like Figure 3 As shown, in order to limit the sliding of the bottom end of the hopper 63, a discharge plate 64 is fixedly provided on the mounting frame 20 at the bottom of the hopper 63, and the first discharge port 60 and the second discharge port 61 are respectively arranged on the discharge plate 64. The top surface of the discharge plate 64 is also provided with a slide groove 65 for allowing the bottom of the hopper 63 to slide between the first discharge port 60 and the second discharge port 61.

[0040] When the hopper 63 slides along the first guide slide rod 31 and the second guide slide rod 32 , the bottom end of the hopper 63 slides in the slide groove 65 and switches between the first discharge port 60 and the second discharge port 61 .

[0041] In order to improve the discharging efficiency of the hopper 63 , a vibration motor 66 is fixedly mounted on the outer side wall of the hopper 63 .

[0042] like Figure 2 As shown, during the discharging process, the snowflake-shaped dry ice particles in the hopper 63 can be quickly discharged from the bottom by relying on the vibration of the vibration motor 66.

[0043] Further, such as Figure 1 As shown, the cleaning device is connected to a feeding pipe 67 mounted on the mounting frame 20, and the feeding pipe 67 is provided with at least one feeding port 68 facing the hopper 63. When there is a need for cleaning, the dry ice material will be delivered to the cleaning device from the feeding pipe 67.

[0044] In one embodiment, the feed pipe 67 is connected to and communicated with an ice supply device (such as an ice maker), and two or more feed ports 68 facing the hopper 63 are provided on the feed pipe 67. During the feeding process, the feed pipe 67 can feed one or more hoppers 63 at the same time, thereby realizing one-to-one, one-to-many, or many-to-many feeding, thereby improving the cleaning efficiency.

[0045] In this embodiment, if Figure 4-7As shown, the discharging mechanism 70 includes a discharging seat 71, a discharging rotor 72 rotatably disposed on the discharging seat 71, a hopper cover 73 covered on the discharging rotor 72, and a driving motor 74 for driving the discharging rotor 72 to rotate. A material bin 75 is provided in the discharging seat 71, the air outlet 76 is provided on a first side of the discharging seat 71 and communicates with the material bin 75, the air inlet 77 is provided on a second side of the discharging seat 71 and communicates with the material bin 75, a feed port 78 is provided on the hopper cover 73, the discharging rotor 72 is located directly below the feed port 78, and a plurality of material troughs 79 are provided on the discharging rotor 72, and the plurality of material troughs 79 are used to transport the material in the hopper cover 73 to the material bin 75 during the rotation of the discharging rotor 72.

[0046] The snowflake-shaped dry ice particles fall onto the hopper cover 73 of the discharging mechanism 70 through the second discharging port 61. The snowflake-shaped dry ice particles falling into the hopper cover 73 eventually enter the material slot 79 of the discharging rotor 72 under the action of their own gravity. During the rotation of the discharging rotor 72, the discharging rotor 72 brings the snowflake-shaped dry ice particles in the material slot 79 into the silo 75, and finally the high-pressure gas blown in by the air inlet 77 blows the snowflake-shaped dry ice particles in the silo 75 out of the air outlet 76. The snowflake-shaped dry ice particles blown out of the air outlet 76 can be used for dry ice cleaning. In the present application, by setting the discharging mechanism 70, the snowflake-shaped dry ice particles can be uniformly and uniformly delivered to the silo 75, and blown out uniformly by the high-pressure gas, achieving a better cleaning effect.

[0047] Furthermore, a partition 80 is provided in the silo 75 to separate the silo 75 into a first chamber 81 and a second chamber 82 . The first chamber 81 is connected to the air outlet 76 , and the second chamber 82 is connected to the air inlet 77 .

[0048] When the trough 79 on the discharging rotor 72 rotates to the partition 80 position, the first chamber 81 and the second chamber 82 are connected through the trough 79, and the high-pressure gas entering from the air inlet 77 can blow the snowflake-shaped dry ice particles in the trough 79 into the first chamber 81 connected to the air outlet 76, thereby realizing air circulation and continuously discharging.

[0049] In this embodiment, the discharging mechanism 70 further includes an air outlet pipe connected to the air outlet 76 and an air inlet pipe connected to the air inlet 77 , and the air inlet pipe is used to communicate with an air compressor.

[0050] The air inlet pipe is used to be connected and communicated with the air compressor, and the air outlet pipe is a snowflake-shaped dry ice particle discharge pipe for cleaning.

[0051] Furthermore, to facilitate the rotational installation of the discharging rotor 72, the discharging seat 71 includes a base and an adapter seat 85 installed on the base. The silo 75 is arranged on the base. The adapter seat 85 is provided with an arc groove 86 for accommodating the discharging rotor 72 for rotation. The bottom of the arc groove 86 is provided with a connecting port 87 connected to the silo 75. The connecting port 87 is provided with a partition plate 88 corresponding to and parallel to the partition 80 and dividing the connecting port 87 into a first channel 89 and a second channel 90. The partition 80 is in contact with the partition plate 88. The first channel 89 is connected to the first chamber 81, and the second channel 90 is connected to the second chamber 82.

[0052] The adapter 85 is connected to the base via a stud 91, and a compressible gasket 92 is provided at the top of the stud 91.

[0053] After high-pressure air is introduced into the air inlet 77, the high-pressure air pushes the adapter 85 upward, the compressible gasket 92 is squeezed, and the adapter 85 moves slightly toward the discharge rotor 72, so that the adapter 85 abuts against the discharge rotor 72 to form a seal. The airflow passes through the air inlet 77, the second chamber 82, the second channel 90, the material trough 79, the first channel 89, the first chamber 81, and finally is discharged through the air outlet 76. During the airflow process, the snowflake-shaped dry ice particles in the material trough 79 are brought into the first chamber 81 and blown out from the air outlet 76.

[0054] During the rotation of the discharging rotor 72 , the dry ice particles in the trough 79 rotate along with the discharging rotor 72 and are finally connected to the silo 75 through the connecting port 87 , thereby realizing the uniform speed transportation of the dry ice particles.

[0055] To prevent the discharging rotor 72 from blocking the first chamber 81 and the second chamber 82 , the plurality of material grooves 79 are staggered on the surface of the discharging rotor 72 , and two adjacent material grooves 79 along the length direction of the discharging rotor 72 are not on the same straight line.

[0056] Since the plurality of material troughs 79 are arranged in a staggered manner, no matter to which angle the discharging rotor 72 rotates, there is a material trough 79 connecting the first chamber 81 and the second chamber 82 , thereby forming an air circulation channel.

[0057] like Figure 1 As shown, the utility model also discloses a multi-station dry ice cleaning system, which includes an ice supply device (not shown) and the cleaning device 10 as described above;

[0058] The feeding port of the ice supply device is connected to the hopper 63 of the cleaning device 10 or is opposite to the hopper 63 of the cleaning device 10 .

[0059] Specifically, the ice supply device is a dry ice making device or a dry ice particle conveying device, etc. The ice supply device includes a feeding pipe 67 mounted on the mounting frame 20, and the feeding pipe 67 is provided with at least one feeding port 68 facing the hopper.

[0060] Preferably, the ice supply device may include two or more feeding ports 68 facing the hopper 63. During the feeding process, multiple feeding ports 68 may feed one or more hoppers 63 simultaneously, thereby realizing one-to-one, one-to-many, or many-to-many feeding and improving cleaning efficiency.

[0061] In this embodiment, the ice supply device is a dry ice making device as an example, and the ice supply device is provided with a raw material hydraulic mechanism and a grinding mechanism. Liquid carbon dioxide is stored in the raw material hydraulic mechanism, and the liquid carbon dioxide is squeezed to become solid dry ice, and the solid dry ice comes out through the mold opening to form dry ice bars, which are then cut and ground to form dry ice particles. However, the above example is only for illustration, and this embodiment does not limit the implementation form of the ice supply device in any way.

[0062] 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.

[0063] 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.
