Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of detection equipment, in particular to a cleaning device for a porous glass plate absorption tube for detecting nitrogen oxides. Background Art

[0002] The porous glass plate absorption tube is a gas absorber that can collect gaseous and vapor substances during nitrogen oxide detection. It is usually U-shaped. Because it is made of glass and the pipe is relatively small and tortuous, it is very inconvenient to clean and can easily cause damage to the tube body.

[0003] When cleaning the glass tube, one end of the glass tube is often directly connected to the faucet for flushing or a long cotton swab is used for cleaning. When flushing with water, only water flows through the glass tube, and stubborn residues cannot be washed away by flushing with water alone, so the cleaning effect is limited. When cleaning with a long cotton swab, the extension distance of the long cotton swab is limited, so the cleaning range is also limited, which is time-consuming and labor-intensive.

It is connected to the inside of the water injection cylinder 1 through a connecting pipe 9, and an end cover 4 is detachably connected to the upper opening of the water injection cylinder 1. A push rod 5 is slidably connected to the end cover 4, and the lower end of the push rod 5 is fixedly connected to a piston head 6 that contacts the inner wall of the water injection cylinder 1. It is worth mentioning that the extension tube 15 is relatively long, which can effectively prevent the backflow of liquid. At the same time, a butterfly valve (not shown in the figure) can be provided at the lower end of the extension tube 15 to prevent the backflow of liquid. The bubble water machine 8 is a prior art, which uses edible grade carbon dioxide to turn ordinary water into bubble water, which is well known to those skilled in the art and will not be repeated here.

[0025] As an optional implementation, a rubber pad 12 is fixedly connected to one end of the insert tube 10 close to the water injection cylinder 1, and a water hole 13 is opened in the middle of the rubber pad 12, and the water hole 13 is in the shape of a long and narrow slit. The elastic force of the rubber pad 12 itself can drive the water hole 13 to close when there is no water pressure, and the water hole 13 automatically opens when squeezed by the water flow.

[0026] Specifically, the lower end of the auxiliary material tank 11 is designed to be inverted conical, so that the activated carbon particles can fall along the slope under the action of gravity to prevent the stock from piling up.

It is worth mentioning that the motor 3d can be a slow-speed motor for slow rotation.

[0028] Specifically, a valve 14 is fixedly installed on the side wall of the connecting pipe 9. The valve 14 can close the connecting pipe 9 when the bubble water machine 8 is not working to prevent the liquid from flowing back and damaging the equipment.

After covering the end cover 4, the piston head 6 is located inside the water injection cylinder 1, and under the action of gravity, the activated carbon particles fall into the insert tube 10 through the extension tube 15. By pressing down the push rod 5, the piston head 6 is driven to move downward in the water injection cylinder 1, and the bubble water is squeezed into the insert tube 10, driving the fallen activated carbon particles to enter the porous glass tube 2 for flushing. During the flushing, the tiny bubbles of the bubble water burst, and the inner wall of the glass tube is cleaned again to complete the flushing.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
