Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of float glass production, in particular to an absorbing device. BACKGROUND

[0002] In the production process of float glass, the forming process is as follows: the molten glass liquid flows out from the melting furnace and flows into the tin bath through the flow guide groove. The tin bath is filled with molten tin liquid, and the density of the molten tin liquid is greater than that of the glass liquid, so that the glass liquid can float on the surface of the tin liquid. Under the action of gravity and surface tension, the glass liquid is naturally flattened on the tin liquid surface and forms a glass ribbon with flat upper and lower surfaces and uniform thickness. The glass ribbon gradually hardens and cools on the tin liquid to achieve sufficient strength and stability.

[0003] In this process, the condition of the tin liquid needs to be detected to ensure the stability of the forming environment. The tin liquid suction device currently used usually needs manpower to pull the piston to generate negative pressure to suck the tin liquid. This method is relatively labor-intensive and inconvenient to operate. The worker needs to hold the suction device and continuously exert force when sucking, which is not convenient for a single person to observe the amount of tin liquid sucked in the glass tube. CONTENT OF THE UTILITY MODEL

[0007] The length direction of the absorbing pipe has two ends, which are the liquid suction end and the connecting end. The connecting end is in sealed connection with the suction end.

[0008] Further, it further comprises an air inlet pipe, the air inlet pipe is connected with the air inlet, and the included angle between the axis of the air inlet pipe and the axis of the airflow pipe is obtuse.

[0009] Further, one end of the air inlet pipe away from the air inlet is provided with a control valve.

[0010] Further, one end of the control valve away from the air inlet is provided with a quick plug connector.

[0015] Further, the suction pipe is a transparent glass pipe.

[0016] Further, the surface of the suction pipe is provided with a liquid level line.

[0017] The beneficial effects of the present application are as follows: the suction device provided by the present application introduces high-pressure gas through the air inlet of the airflow pipe, and the high-pressure gas flows out along the airflow pipe along the air outlet end, thereby forming a negative pressure area at the suction end of the airflow pipe, and the suction pipe connected with the suction end sucks the molten tin liquid under the action of negative pressure.
