Description

Technical Field

[0001] This utility model relates to the field of dry ice cleaning machines, and in particular to a dry ice cleaning machine with adjustable particle size. Background Technology

[0002] A dry ice cleaner is a type of cleaning machine that uses high-pressure air to propel dry ice particles onto the work surface to be cleaned. The temperature difference causes different substances to detach at different rates of contraction. However, most existing dry ice cleaners rely on vibrating motors to prevent the dry ice from freezing. These vibrating motors generate significant noise pollution. Larger dry ice cleaners, in particular, require even larger vibrating motors, resulting in even greater noise. Furthermore, existing dry ice cleaners do not allow for adjustment of the dry ice particle size. Utility Model Content

A rotating ice-crushing blade effectively prevents dry ice from freezing, replacing a vibrating motor and effectively reducing noise. An adjustable gap mechanism adjusts the distance between the rollers of the roller ice crusher, thereby achieving the purpose of adjusting the dry ice particle size.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Figure 1 This is a first-view structural schematic diagram of the present invention; Figure 2 This is a structural schematic diagram of the present invention from a second perspective; Figure 3 This is a structural schematic diagram of the roller ice crusher and the adjusting mechanism of this utility model; Figure 4 This is a schematic diagram of the ice-spraying mechanism of this utility model.

[0021] Combined with appendix Figure 1 and attached Figure 2 As shown, a dry ice cleaning machine with adjustable particle size includes a hopper 1, an ice shovel 2, a turntable 3, a base 4, a roller ice crusher 5, an adjusting mechanism 6, an ice spraying mechanism 7, and a rotating mechanism 8. The hopper 1 is fixed to the upper end face of the base 4. The body of the rotating mechanism 8 and the roller ice crusher 5 are both fixed to the lower end face of the base 4. The output shaft of the rotating mechanism 8 is fixed to the center of the turntable 3 and the ice shovel 2. The ice shovel 2 is located inside the hopper 1, and the turntable 3 is located below the hopper 1. Several through holes 31 for passing dry ice are distributed on the turntable 3. The base 4 is provided with through holes 2 for passing dry ice. The inlet of the roller ice crusher 5 is located below the through holes 2. An adjusting mechanism 6 for adjusting the roller spacing is installed on the roller ice crusher 5. An ice spraying mechanism 7 is fixed on the roller ice crusher 5.

[0022] As attached Figure 3 As shown, the roller ice crusher 5 includes a frame 51, a slide table 52, a first motor 53, a first roller 54, a second motor 55, and a second roller 56. The slide table 52 is slidably connected to a linear slide rail inside the frame 51. The body of the first motor 53 is fixed on the frame 51, and the first roller 54 is fixed on the output shaft of the first motor 53. The body of the second motor 55 is fixed on the slide table 52, and the second roller 56 is fixed on the output shaft of the second motor 55.

[0023] Motor 1 53 drives roller 1 54 to rotate, and motor 2 55 drives roller 2 56 to rotate. When dry ice particles enter between the rotating roller 1 54 and roller 2 56, they are squeezed, broken, and fall off.

[0024] The adjusting mechanism 6 is a screw, which is rotatably connected to the frame 51. The screw body is threaded into a screw hole in the end plate of the slide table 52. Rotating the screw in both directions pushes the slide table 52, which is threaded to it, to move back and forth linearly. This, in turn, moves roller 2 56 back and forth, thus adjusting the distance between roller 2 56 and roller 1 54. By adjusting the distance, the particle size of the crushed dry ice can be adjusted.

[0025] As attached Figure 4As shown, the ice-spraying mechanism 7 includes a housing 71, a roller 72, a hopper 73, an air pump, and a roller rotation motor. The roller 72 is rotatably connected inside the housing 71. Several grooves for holding dry ice are distributed on the cylinder of the roller 72. The roller 72 is fixed on the output shaft of the roller rotation motor. The hopper 73 is fixed below the housing 71. The housing 71 and the hopper 73 are connected. The rear end of the hopper 73 is connected to the air pump, and the front end of the hopper 73 is provided with a discharge port 74.

[0026] When dry ice pellets fall into the groove of the drum 72, the drum rotation motor drives the drum 72 to rotate inside the housing 71. When the groove containing the dry ice rotates to face downwards, the dry ice will fall into the hopper 73. The air pump will then blow the dry ice pellets out from the outlet 74 using high-pressure air.

[0027] The ice scrambler 2 includes a straight rod 21 and a protrusion 22. The center of the straight rod 21 is fixed on the output shaft of the rotating mechanism 8, and the two ends of the straight rod 21 are provided with protrusions 22.

[0028] The rotating mechanism 8 is either an electric motor or a rotary cylinder.

[0029] The working method of this application is as follows: First, dry ice is poured into hopper 1. Rotating mechanism 8 drives ice shovel 2 and turntable 3 to rotate. Ice shovel 2 can effectively prevent the dry ice from freezing and causing difficulties in ice discharge. The dry ice falls through the through hole 31 on the turntable 3 into roller ice crusher 5, which grinds the dry ice into dry ice particles of a preset size. Finally, the dry ice particles fall into ice spraying mechanism 7, which sprays the dry ice particles outward.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
