Abstract

The invention relates to a cooling water drainage device for cooling cylinders in the industry of papermaking and the like, in particular to a novel siphon type drainage device for a cooling cylinder.The device mainly comprises a self-supporting rotating joint and a siphon, a horizontal drainage pipe and a water inlet pipe forming the siphon are of a concentric sleeving structure, one end of thewater inlet pipe is fixed in a casing of the rotating joint, the other end is closed on the outer diameter of the horizontal drainage pipe, and a water spraying hole is drilled in the end part to spray water into the cooling cylinder. One end of the horizontal drainage pipe is fixed in the casing of the rotating joint, and the other end is connected with a vertical drainage pipe in the cooling cylinder. The rotating joint is supported on a shaft head of the cooling cylinder through a support sleeve and a bearing, and after compressed air under 0.01-0.05 MPa is introduced into the cylinder viaan air hole in the rotating joint, cooling water in the cooling cylinder can be continuously drained.

Description

technical field [0001] The invention relates to a cooling water discharge device for cold cylinders in industries such as papermaking, in particular to a novel suction pipe type cold cylinder drainage device. Background technique [0002] There are three main types of cold cylinder drainage devices commonly used at present. [0003] One is a bucket type drainage device, and the bucket is fixed on the cylinder head of the transmission side in the drying cylinder. When the drying cylinder is rotated, the bucket will pour cooling water into the lower part of the drying cylinder, and then flow into the annular space between the inner wall of the shaft head and the air supply pipe to discharge. The drainage device of the cold cylinder with this structure is more complicated, and the drainage is intermittent and uneven. But when the vehicle speed is higher than 350-400 m / min, the cooling water is subjected to centrifugal force and forms a condensed water ring, and the required dr...
