Abstract
Description
Technology Field
[0001] The present invention relates to a dry ice optimization device for a dry ice cleaning machine, and more specifically, to a dry ice optimization device for a dry ice cleaning machine that optimizes the dry ice introduced into the hopper of the dry ice cleaning machine so that it does not vaporize or clump together. Background Technology
[0002] When dry ice is exposed to air, it rapidly vaporizes and solidifies. Dry ice is fed into the hopper of a dry ice cleaning machine; however, if the dry ice vaporizes within the hopper, it becomes stagnant and cannot descend to the grinder located below. This phenomenon is a critical issue in the development of dry ice cleaning machines, and the quality of the machine depends on how it is improved. Traditionally, vibrators were primarily used, but they are noisy, prone to frequent breakdowns, and require the inconvenience of constantly replenishing lubricant. If a vibrator sized to fit a 35kg hopper and grinder body were installed, the resulting noise would be so significant that the equipment could not be installed indoors.
[0003] A dry ice cleaning machine using a conventional vibrator device is disclosed in Utility Model Registration No. 20-0403856. Referring to FIG. 6, the dry ice cleaning machine comprises a hopper (20) into which a dry ice pellet (10) is fed, a disc device (30) that supplies the dry ice pellet (10) through the hopper (20), and a dry ice cleaning machine that performs cleaning by spraying the dry ice pellet supplied by the disc device (30) at high pressure. Typically, the principle of blasting dry ice pellets as described above is that when high-pressure air is sprayed at a high speed, the dry ice itself is at an ultra-low temperature (-79℃), so it rapidly freezes the foreign substance layer on the surface of the material, causing numerous cracks in the foreign substance layer, and the pellet penetrates under the foreign substance layer through the cracks and simultaneously sublimates (solid to gas). At this time, the pallet expands to more than 700-800 times its volume, instantaneously separating the material and the foreign matter layer to perform cleaning.
[0004] To this end, a solid dry ice pellet (10) is introduced into a hopper (20) having a shape that is wider at the top and narrower at the bottom, and the introduced dry ice pellet (10) is guided into the hopper (20) and moves downward. A vibrator (40) is installed in the hopper (20) to generate vibration, and the vibration is transmitted to the dry ice pellet (10) to align the dry ice pellet (10) and sequentially move it to the bottom of the hopper (20). An outlet (22) is formed at the bottom of the hopper (20), and the dry ice pellet (10) is discharged to the outside through the outlet (22). The vibration by the vibrator (40) causes the dry ice pellet (10) to move downward and ensures that the pellet is supplied uniformly to the outlet (22) so that the pellet does not clump together. To this end, the upper and lower casings (32, 36) forming the disk device (30) are joined together at the lower end of the outlet (22) of the hopper (20).
[0005] A disc disk (34) that performs the function of a disk is rotatably installed between the upper and lower casings (32, 36) and serves to supply the extracted dry ice pellet (10) through the disc disk (34). At this time, the disc device (30) according to the present invention temporarily receives the dry ice pellet (10) extracted through the hopper (20).
[0006] It is uniformly crushed by a rotating disc (34).
[0007] In the conventional utility model registration described above, a vibrator is used, but there is a problem with excessive noise. The problem to be solved
[0008] Therefore, the objective of the dry ice optimization device of the dry ice cleaning machine according to the present invention, which solves the conventional problems as described above, is to prevent the dry ice from solidifying by rapidly moving the hopper and grinder up and down with four cylinders, thereby causing the dry ice inside the hopper to fly up within 2 to 3 mm instantaneously. means of solving the problem
[0009] As an example of a dry ice optimization device for a dry ice cleaning machine according to the present invention, the device comprises four legs, two connecting plates connecting two legs in the longitudinal direction, a support plate that supports a grinder body on the upper part of the connecting plates and is capable of vertical movement, and A vertical cylinder device comprising four cylinders and mounting rods connected to the cylinders, and The grinder body is coupled to the support plate above, and the grinder body and the hopper move up and down together by the raising and lowering of the cylinder.
[0010] As another example of a dry ice optimization device for a dry ice washing machine according to the present invention,
[0011] It further includes dampers attached to the four corners of the support plate and stoppers mounted on the upper part of each leg.
[0012] As another example of a dry ice optimization device for a dry ice washing machine according to the present invention,
[0013] The upper end of the mounting rod of the cylinder is fixed to a hole in the support plate through a hole formed in the connecting plate, the cylinder is fixed to the connecting plate, and auxiliary brackets are fixed to both connecting plates to reinforce the fixing force of the connecting plate. Effects of the invention
[0014] In the dry ice optimization device of the dry ice cleaning machine according to the present invention, each of the four mounting rods of the four cylinders moves up and down simultaneously, and then the support plate connected to the mounting rod moves up and down, thereby causing the grinder body and the hopper to move up and down together. This movement proceeds rapidly and is repeated once every 15 to 30 seconds, so that the dry ice inside the hopper is instantaneously lifted into the air by about 2 to 3 mm, thereby preventing the dry ice from solidifying. Since the cylinders instantaneously and rapidly move the grinder body and the hopper up and down, almost no noise is generated, and the vaporization and solidification of the dry ice can be prevented in a shorter time than the conventional vibrator method.

[0016] The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

Furthermore, in describing the present invention, if it is determined that a detailed description of related known components or functions could obscure the essence of the present invention, such detailed description is omitted.
[0019] The features and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments based on the accompanying drawings.

[0025] Hereinafter, in describing an embodiment of the present invention in detail with reference to the drawings, the same reference numerals are used for identical components, and for clarity, only the different parts are described primarily to avoid duplication as much as possible.
[0026] Figures 1 and 2 are a side view and a cross-sectional view along line AA of a typical dry ice cleaner.
[0027] It includes a hopper (105) having a shape that is wider at the top and narrower at the bottom into which dry ice is introduced, a grinder body (110) having a built-in grinder that grinds the dry ice introduced into the hopper (105) as it descends, and a motor (115) for driving the grinder.
[0028] Dry ice blasting is a cleaning method that sprays dry ice (solid carbon dioxide) onto a surface at high speed. As dry ice particles collide with the surface, they remove contaminants through physical, thermal, and vaporization effects.
[0029] The grinder is used to crush dry ice. The crushed dry ice is used for precision cleaning and precision deburring. Before crushing, the dry ice is in the form of pellets approximately 3 pi in diameter and 30 mm in length; however, since this is too large to be used for precision cleaning and precision deburring, the particle size of the dry ice can be controlled by adjusting the grinder's gap.
[0030] Referring to FIGS. 3 to 5, FIG. 3 is a perspective view of a vertical cylinder device of a dry ice optimization device of a dry ice cleaning machine according to the present invention, FIG. 4 is an exploded perspective view of a vertical cylinder device of a dry ice optimization device of a dry ice cleaning machine according to the present invention, and FIG. 5 is a perspective view of the cylinder lowered state (A) and raised state (B) of the dry ice optimization device of a dry ice cleaning machine according to the present invention.
[0031] The vertical cylinder device (200) is composed of four legs (205), two connecting plates (210) connecting two legs, a support plate (230) that supports the grinder body (110) on the upper part of the connecting plates (210) and is movable up and down, a damper (220) attached to the four corners of the support plate (230), a stopper (215) mounted on the upper part of each leg (205), four cylinders (250), and a mounting rod (255) connected to the cylinders (250).
[0032] The cylinder (250) can be selected from various types, such as pneumatic cylinders and hydraulic cylinders.
[0033] The upper end of the mounting rod (255) of the cylinder (250) is fixed to the hole (222) of the support plate (230) through the hole (212) formed in the connecting plate (210), and the cylinder (250) is fixed to the connecting plate (210).
[0034] To strengthen the fixing force of the connecting plate (210), an auxiliary bracket (217) is fixed to both connecting plates (210).
[0035] With the above configuration, the dry ice optimization device of the dry ice washing machine according to the present invention is assembled and operated as follows.
[0036] Four legs (205) are prepared, and a connecting plate (210) is connected to each of the longer sides, and the connecting plates (210) are connected to each other by an auxiliary bracket (217). A cylinder (25) is fixed to the connecting plate (210), and a support plate (230) is fixed to the upper end of the mounting rod (255). The support plate (230) is not fixed to the legs (205). The grinder body (110) is attached to the support plate (230).
[0037] The lowered state of the mounting rod (255) of the cylinder (250) is shown in FIG. 5(a), and the raised state is shown in FIG. 5(b).
[0038] In FIG. 5(a), when the mounting rod (255) of the cylinder (250) is lowered, the distance between the damper (220) fixed to the support plate (230) and the stopper (215) fixed to the top of the leg (205) is separated by less than 10 mm.
[0039] In FIG. 5(b), when the mounting rod (255) of the cylinder (250) is raised, the damper (220) fixed to the support plate (230) and the stopper (215) fixed to the top of the leg (205) come into contact.
[0040] Each of the four mounting rods (255) of the four cylinders (25) moves up and down simultaneously. Then, the support plate (230) connected to the mounting rod (255) moves up and down, and as a result, the grinder body (110) and the hopper (105) also move up and down together. This up-and-down movement proceeds rapidly and is repeated once every 15 to 30 seconds, causing the dry ice inside the hopper (105) to fly up into the air within about 2 to 3 mm.
[0041] This makes it possible to prevent the dry ice from solidifying.
[0042] Since the cylinder (250) rapidly raises and lowers the grinder body (110) and the hopper (105) instantaneously, almost no noise is generated, and the vaporization and hardening of dry ice can be prevented in a shorter time than with conventional vibrator methods.
[0043] Although the present invention has been illustrated and described with preferred embodiments as described above, it is not limited to the embodiments described above, and it is obvious that various modifications and variations are possible within the scope of the technical concept of the present invention and the equivalent scope of the claims to be described below by those skilled in the art without departing from the spirit of the invention.
