Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide cleaning, in particular to a carbon dioxide cleaning device. Background Art

[0002] The carbon dioxide cleaning device is a device that uses the special properties of carbon dioxide for cleaning. It achieves cleaning by converting liquid carbon dioxide into snow-like or gaseous carbon dioxide. Under a certain pressure and temperature, liquid carbon dioxide rapidly expands into gas. The high-speed sprayed carbon dioxide liquid or snow-like carbon dioxide particles can impact the dirt on the surface of the object and peel it off the object being cleaned.

[0003] Carbon dioxide cleaning devices are often used to clean tanks. A nozzle is inserted into the tank, and multiple nozzles are provided on the nozzle. High-speed carbon dioxide gas is sprayed out from the nozzles to remove dirt inside the tank.

[0004] However, the nozzle direction of this carbon dioxide cleaning device is fixed. Although multiple nozzles are provided, there is a gap between adjacent nozzles. The spray sprayed from the nozzles diffuses, but the impact force of the diffused carbon dioxide gas on the dirt is reduced, affecting the cleaning effect. Utility Model Content

[0005] The purpose of the utility model is to propose a carbon dioxide cleaning device to solve the problem in the background technology that the spacing between adjacent nozzles affects the cleaning effect.

[0007] The cyclone assembly includes a straight pipe, a nozzle, a branch pipe, and a connecting plate. The nozzle is rotatably connected to the inner wall of the straight pipe. A plurality of branch pipes are fixedly installed on the top of the nozzle. The ends of the plurality of branch pipes are fixedly installed with the same connecting plate. The connecting plate is rotatably connected to the inner wall of the straight pipe.

[0008] The end of the straight pipe is connected to the hard pipe, and a plurality of branch pipes are distributed in a circular manner at equal angles on the top of the nozzle.

[0009] Optionally, the nozzle is provided with a plurality of nozzles, the number of the nozzles is the same as the number of the branch pipes, each of the branch pipes is individually connected to a nozzle, and the branch pipes have a spiral structure.

[0010] Optionally, a support column passing through the centers of the plurality of branch pipes is fixedly installed at the bottom center of the connection plate, and the other end of the support column is fixedly connected to the nozzle.

[0011] Optionally, an extension hose is fixedly installed between the hard pipe and the straight pipe, and the branch pipe, the straight pipe and the extension hose are connected to each other.

[0012] Optionally, a seal is provided on the outer wall of the straight tube, and the seal includes a pressure plate, a cylinder and an airbag. The pressure plate slides on the outer wall of the straight tube, the bottom of the pressure plate is fixedly installed with a cylinder, the bottom of the cylinder is fixedly installed with an airbag, and the bottom of the pressure plate is placed on the top of the tank to be cleaned.

[0013] Optionally, the outer wall of the airbag is connected to an external air inlet pipe, the external air inlet pipe passes through the inside of the pressure plate and the cylinder, and an air pump is fixedly installed in the middle of the external air inlet pipe.

[0028] Example 1

[0029] This embodiment proposes a carbon dioxide cleaning device, such as Figure 1 As shown, the cleaning machine comprises a housing 1 , a plurality of carbon dioxide tanks 2 are fixedly mounted on the top of the cleaning machine housing 1 , and a hard pipe 3 is fixedly mounted on the top of the carbon dioxide tank 2 .

[0030] Further, such as Figure 2 and 3As shown, the end of the rigid tube 3 is provided with a cyclone assembly 4, comprising a straight tube 41, a nozzle 42, branch pipes 43, and a connecting plate 44. The nozzle 42 is rotatably connected to the inner wall of the straight tube 41. Multiple branch pipes 43 are fixedly mounted on the top of the nozzle 42. The nozzle 42 is provided with multiple nozzles, the same number of nozzles as the branch pipes 43. Each branch pipe 43 is connected to a nozzle, and the branch pipes 43 have a spiral structure. The end of the straight tube 41 is connected to the rigid tube 3, and multiple branch pipes 43 are distributed at equal angles in a ring shape on the top of the nozzle 42.

[0031] The liquid carbon dioxide inside the carbon dioxide tank body 2 enters the straight pipe 41 through the hard pipe 3, and then the liquid carbon dioxide enters the branch pipe 43 from the straight pipe 41. Since the branch pipe 43 adopts a spiral structure, after the liquid carbon dioxide enters the branch pipe 43, the branch pipe 43 is rotated by the thrust of the liquid carbon dioxide, and multiple branch pipes 43 rotate at the same time, thereby causing the nozzle 42 to rotate, thereby changing the position of the nozzle on the nozzle 42, so that the liquid carbon dioxide can better clean the dirty tank body.

[0032] like Figure 1 and 2 As shown, an extension hose 46 is fixedly installed between the rigid tube 3 and the straight tube 41. Liquid carbon dioxide is stored inside the CO2 tank 2, and a solenoid valve is installed inside the extension hose 46, connecting the extension hose 46 to the CO2 tank 2. The branch pipe 43, the straight tube 41, and the extension hose 46 are interconnected. The extension hose 46 serves as an intermediate component to expand the range of movement of the straight tube 41.

[0033] The ends of multiple branch pipes 43 are fixedly installed with the same connecting plate 44, which is rotatably connected to the inner wall of the straight pipe 41. A support column 45 passing through the center of multiple branch pipes 43 is fixedly installed at the bottom center of the connecting plate 44, and the other end of the support column 45 is fixedly connected to the nozzle 42; the connecting plate 44, the support column 45 and the nozzle 42 cooperate to provide support force for the branch pipes 43.

[0034] In this embodiment, liquid carbon dioxide enters the branch pipe 43. Since the branch pipe 43 adopts a spiral structure, the liquid carbon dioxide will apply thrust to the branch pipe 43, thereby causing the branch pipe 43 and the nozzle 42 to rotate, so that the position of the nozzle on the nozzle 42 changes, thereby increasing the cleaning range of the liquid carbon dioxide and avoiding the existence of blind spots in cleaning that affect cleaning.

[0035] Example 2

[0036] Based on Example 1, this example proposes a carbon dioxide cleaning device, such as Figure 4As shown, the outer wall of the straight tube 41 is provided with a seal 5, and the seal 5 includes a pressure plate 51, a cylinder 52 and an air bag 53. The pressure plate 51 slides on the outer wall of the straight tube 41, and the bottom of the pressure plate 51 is fixedly installed with the cylinder 52, and the bottom of the cylinder 52 is fixedly installed with the air bag 53. The bottom of the pressure plate 51 is placed on the top of the tank to be cleaned.

[0037] The outlet of the tank body being cleaned is blocked by the pressure plate 51 to prevent leakage of carbon dioxide, resulting in a reduction in the carbon dioxide recovered into the carbon dioxide tank body 2.

[0038] The outer wall of the air bag 53 is connected to an external air inlet pipe 54 , which passes through the inside of the pressure plate 51 and the cylinder 52 . An air pump is fixedly installed in the middle of the external air inlet pipe 54 .

[0039] By starting the air pump, external gas is filled into the interior of the airbag 53, thereby expanding the airbag 53 and further improving the sealing effect of the tank body.

[0040] In this embodiment, gas is filled into the airbag 53, so that the airbag 53 expands and blocks the outlet of the tank body to be cleaned. The airbag 53 cooperates with the pressure plate 51 to achieve the effect of sealing the outlet of the tank body to be cleaned, thereby preventing carbon dioxide leakage, resulting in a reduction in carbon dioxide recovered into the carbon dioxide tank body 2.

[0041] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
