Description

Technical Field

[0001] The utility model relates to the technical field of cleaning machines, in particular to a cleaning machine using liquid carbon dioxide and dry ice. Background Art

[0002] Carbon dioxide cleaning machine is a type of cleaning machine. Carbon dioxide cleaning has been rapidly developed around the world. The cleaning system uses high-pressure air to spray solid carbon dioxide particles from the solid carbon dioxide cleaning machine onto the working surface that needs to be cleaned, and uses the physical reaction of temperature difference to make different substances separate at different shrinkage speeds. When the solid carbon dioxide particles at minus 78°C come into contact with the dirt surface, they will produce a brittle explosion phenomenon, causing the dirt to shrink and loosen. Then the solid carbon dioxide particles will instantly gasify and expand 800 times, generating a strong peeling force, quickly and thoroughly removing the dirt from the surface of the object, thereby achieving a fast, efficient, safe and energy-saving cleaning effect.

[0003] A liquid carbon dioxide cleaning machine with publication number CN215613770U includes a chassis, a power interface is provided at the rear end of the chassis, a nitrogen channel, a heater, a carbon dioxide channel and a confluence are provided inside the chassis, the nitrogen channel is provided on the right side inside the chassis, a nitrogen connection port is provided at the input end of the nitrogen channel, the nitrogen connection port extends through the rear end of the chassis to the outside, and the output end of the nitrogen connection port is connected to the input end of the heater.

[0004] The above device can form tiny solid carbon dioxide in the shape of snowflakes to clean precision components without causing wear to the outer surface of the parts during cleaning. Solid carbon dioxide is sprayed from a spray gun. If the distance between the spray gun nozzle and the workpiece to be cleaned is very close, the sprayed carbon dioxide will accumulate in one place, affecting the worker's line of sight, making it difficult to judge whether the outer surface of the workpiece to be cleaned is thoroughly cleaned, and repeated cleaning work is likely to occur. If the distance between the spray gun nozzle and the workpiece to be cleaned is far, the carbon dioxide content per unit volume will be reduced, the concentration will be reduced, the cleaning effect will be affected, and the appropriate distance of the nozzle cannot be constantly reminded.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 A dry ice cleaning machine using liquid carbon dioxide comprises a bottom plate 1, a dry ice cleaning machine body 2 is installed on the upper surface of the bottom plate 1, a liquid carbon dioxide barrel 7 and a nitrogen barrel 8 are placed above the bottom plate 1, the liquid carbon dioxide barrel 7 and the nitrogen barrel 8 are connected with the dry ice cleaning machine body 2 through pipelines, and by starting the dry ice cleaning machine body 2, the raw materials inside the liquid carbon dioxide barrel 7 and the nitrogen barrel 8 can be extracted, and after being processed by the dry ice cleaning machine body 2, they are sprayed to the parts to be cleaned through the nozzle 5.

[0024] A pipe winding mechanism 3 is arranged above the bottom plate 1, and the pipe winding mechanism 3 includes a winding cylinder 301, and a liquid delivery pipe 4 is wound around the outer surface of the winding cylinder 301, and the water outlet end of the liquid delivery pipe 4 extends to the right side of the entire device, and the front and rear sides of the winding cylinder 301 are fixedly connected with side baffles 302. By using the side baffles 302, the winding range of the liquid delivery pipe 4 can be limited to prevent the liquid delivery pipe 4 from slipping out of the winding cylinder 301.

[0025] The side surfaces of the two side baffles 302 that are away from each other are fixedly connected to the support rods 303, and the outer surfaces of the two support rods 303 are rotatably connected to the support plates 306. The bottom surfaces of the two support plates 306 are fixedly connected to the upper surface of the bottom plate 1. By using the two support plates 306, the support rods 303 can be supported, thereby supporting the rotation of the winding tube 301.

[0026] A liquid outlet 12 is installed on the front of the dry ice cleaning machine body 2, an outer wall groove 304 is provided inside the winding tube 301, and a middle through groove 305 is provided inside the front support rod 303. The water inlet end of the liquid delivery pipe 4 passes through the outer wall groove 304 and the middle through groove 305 in sequence and is connected with the liquid outlet 12, and the outer surface of the liquid delivery pipe 4 contacts the inner wall of the outer wall groove 304 and the middle through groove 305. When the winding tube 301 rotates, the water inlet end of the liquid delivery pipe 4 will not rotate with it due to the connection with the liquid outlet 12, while the water outlet end will be pulled far away.

[0027] A nozzle 5 is installed at the water outlet end of the liquid delivery pipe 4, and an identification mechanism 6 is arranged on the outside of the liquid delivery pipe 4. The identification mechanism 6 includes a horizontal rod 601, and the right end of the horizontal rod 601 is rotatably connected to a rotatable rod 602, and the right end of the rotatable rod 602 is fixedly connected to a support block 603. The outer surface of the support block 603 is rotatably connected to two hemispherical blocks 604 through a rotating shaft. When the two hemispherical blocks 604 contact the part to be cleaned, as the position of the nozzle 5 changes, the hemispherical blocks 604 will also move accordingly. The rotatable connection between the hemispherical block 604 and the support block 603 can facilitate the sliding of the hemispherical block 604 on the outer surface of the part to be cleaned, and the rotatable connection between the horizontal rod 601 and the rotatable rod 602 can facilitate the rotation of the moving direction of the hemispherical block 604.

[0028] The outer surface of the horizontal rod 601 is slidably connected with a positioning plate 605, and the inner wall of the positioning plate 605 is fixedly connected to the outer surface of the liquid delivery tube 4. The positioning plate 605 can be used to connect the liquid delivery tube 4 to the horizontal rod 601, so that the positioning plate 605 can support the horizontal rod 601.

[0029] The left end of the horizontal rod 601 is fixedly connected to the end plate 606, and the outer surface of the horizontal rod 601 is sleeved with a spring 607. The left and right ends of the spring 607 are respectively fixedly connected to the right side of the end plate 606 and the left side of the positioning plate 605. By using the elastic force of the spring 607, the hemispherical blocks 604 can be prevented from squeezing the substitute cleaning parts when the two hemispherical blocks 604 come into contact with the substitute cleaning parts.

[0030] A push handle 9 is installed on the upper surface of the base plate 1 , and four moving wheels 10 are installed on the bottom surface of the base plate 1 .

[0031] A grip sleeve 11 is installed on the outer surface of the liquid delivery pipe 4 . By using the grip sleeve 11 , a worker can better grip the liquid delivery pipe 4 .

[0032] Working principle: When liquid carbon dioxide is needed to clean the object to be cleaned, the raw materials inside the liquid carbon dioxide barrel 7 and the nitrogen barrel 8 can be extracted by starting the dry ice cleaning machine body 2, and flow to the liquid delivery pipe 4 and the nozzle 5 through the liquid outlet 12, so that the nozzle 5 can be sprayed to the object to be cleaned, and the carbon dioxide can be used to clean the object to be cleaned. When cleaning the object to be cleaned, the two hemispherical blocks 604 can be abutted against the object to be cleaned. Under the action of the rotational connection between the horizontal rod 601 and the rotatable rod 602 and the support block 603 and the hemispherical block 604, the hemispherical block 604 can be assisted to move when it contacts the object to be cleaned. The horizontal rod 601 cooperates with the hemispherical block 604 to indicate the appropriate cleaning range of the nozzle 5, which is conducive to improving the efficiency of workers when using liquid carbon dioxide to clean the object to be cleaned.
