Abstract

The invention relates to the technical field of heavy-duty rotary joints. A heavy-duty rotary joint comprises a joint body and an inner tube installed in the joint body. The joint body is also connected with a bearing, the bearing is mounted with a rotary tube, and the inner tube is installed in the joint body. A conveying device is rotatably connected to the pipe. The conveying device includes a sliding sleeve. The sliding sleeve is sleeved on the inner pipe. The device comprises a straight groove, the straight groove is arranged on the inner wall of the rotating pipe, a sliding block is slidably connected in the straight groove, the sliding block is connected with the straight groove through a first spring, and the sliding block is connected with the spiral sleeve. Through the cooperation of the rotating tube and the screw sleeve, the invention uses the screw arrangement of the screw sleeve to quickly transport the liquid, so that the device does not use the flow of the liquid itself to circulate, but transfers the liquid through the rotation of the screw sleeve.

Description

technical field [0001] The invention relates to the technical field of heavy-duty rotary joints, in particular to a heavy-duty rotary joint. Background technique [0002] With the rapid development of society and economy, rotary joints refer to: pipeline connection devices, and the connected pipelines can be rotated relative to each other, which can be used to transmit various media such as gas, liquid, oil, etc., compact design structure, flange-type connection, Effectively integrated into customer equipment, the application fields of rotary joints cover almost all processing and manufacturing industries, such as: metallurgy, machine tools, power generation, petroleum, rubber, plastics, textiles, printing and dyeing, pharmaceuticals, cigarettes, paper, food and feed processing, etc. [0003] However, the existing heavy-duty rotary joint can only rely on the liquid to overflow into the heavy-duty rotary joint to complete the circulation, resulting in a slow circulation of wa...
