Fluid transition water sealing device for rotatable pipeline and water sealing method

Abstract

The invention discloses a fluid transition water sealing device for a rotatable pipeline. The fluid transition water sealing device comprises sliding sleeves which are fixedly mounted on rotatable shaft heads and can rotate along the rotatable shaft heads, fluid transition pipes fixedly arranged through supporting seats, one end of each fluid transition pipe being connected internally to each sliding sleeve in a sleeving manner, and sealing mechanisms arranged between the fluid transition pipes and the sliding sleeves, wherein the sealing mechanisms comprise annular water storage tanks arranged along the circumferential directions of the outer walls of the fluid transition pipes, water supply tanks which are arranged on the outer walls of the fluid transition pipes and are communicated to the outside through the water storage tanks, and sealing rings arranged between the sliding sleeves and the fluid transition pipes; the water storage tanks are arranged between the rotatable shaft heads and the sealing rings. According to the fluid transition water sealing device, water protection layers can be formed between the sliding sleeves and the fluid transition pipes and can continuously drain water to one side of each rotatable shaft head, to effectively prevent mud from entering the sealing device; furthermore, cooling can be provided for the relative rotation motion between the sliding sleeves and the fluid transition pipes, and wear between the sliding sleeves and the fluid transition pipes can be effectively relieved; the fluid transition water sealing device is applicable to sealing for transition of all types of fluid.

Description

technical field [0001] The invention relates to the technical field of intermediate transition sealing, in particular to a fluid transition water sealing device and a water sealing method for a rotary pipeline. Background technique [0002] In the prior art, the intermediate transition device for combined continuous ball mill generally adopts skeleton oil seal or rubber sealing ring or rubber sealing gasket, but the intermediate transition device of this structure generally has different degrees of slurry leakage. Due to the characteristics of some coarse particles in the ceramic mud, once the slurry leaks, the mud will enter the sealing device, and the sealing device is also a rotary pipe for mud transition. The mud in the rotary pipe will accelerate the wear of the sealing device, thereby intensifying the mud The leakage phenomenon, thus forming a vicious circle, brings great inconvenience to the production of the continuous ball mill. In addition, since the installation ...
