Description

Technical Field

[0001] The utility model relates to the technical field of rotary joints, and particularly relates to a rotary joint that is easy to replace. Background Technique

[0002] A rotary joint is a rotating mechanical seal device that is mainly used to transport and discharge heat transfer media between a fixed pipeline and a rotating roller. This device can ensure that fluid leakage does not occur when the mechanical equipment rotates or swings. Rotary joints have a wide range of applications, including but not limited to the transportation of fluids such as steam, water, heat transfer oil, hydraulic oil, and coolant. Their design structures are diverse, including double-circuit rotary joints, etc. Through precise sealing technology, the effective transmission of fluid in rotating or swinging equipment is ensured, while preventing fluid leakage or mixing. In order to ensure the normal operation and safety of the equipment, a rotary joint is required. However, the existing rotary joints still have the following deficiencies:

[0003] For example, the utility model with the application number 202222993343.5 discloses a multi-pass rotary joint. This utility model can increase the space utilization rate, be smaller in volume, have a smaller diameter of the rotating shaft, optimize the structure, connect the external circulating coolant to the circulation circuit on the housing, and the temperature of the housing can be known through the set temperature sensor. When the temperature is too high, the external circulating coolant enters the interior of the housing to cool the housing and the rotating shaft, thereby increasing the service life. However, for comparative documents similar to the above application, when the existing rotary joints are in use, since most rotary joints are docked and installed through multiple bolts, it is difficult to disassemble and replace them during the subsequent use of the rotary joint, which affects the subsequent maintenance and repair of the rotary joint, resulting in a decrease in the practicality and use efficiency of the rotary joint.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a rotary joint that is easy to replace is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rotary joint that is easy to replace, so as to solve the problems put forward in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A rotatable joint that is easy to replace, comprising a rotatable joint body and a mounting assembly. A filter cartridge is connected to the front end of the rotatable joint body, and a connecting pipe is provided in the middle of the outer part of the filter cartridge. An mounting assembly is provided at the front end of the rotatable joint body, and the mounting assembly includes a docking ring, a limiting chute, a limiting slider, a flange connection disc, a mounting groove, a rubber sealing ring, and a fastening bolt. Limiting chutes are opened at both ends inside the docking ring, and limiting sliders are connected inside the limiting chutes. A flange connection disc is provided at the front end of the filter cartridge, and a mounting groove is opened inside the flange connection disc. A rubber sealing ring is provided inside the mounting groove. A fastening bolt is connected inside the flange connection disc. A filter assembly is provided inside the filter cartridge.

[0007] Further, the inner dimension of the limiting chute is adapted to the outer dimension of the limiting slider, and the docking ring is slidably connected to the rotatable joint body through the limiting slider.

[0008] Further, the number of the limiting sliders is two, and the two limiting sliders are symmetrically arranged at both ends inside the rotatable joint body with respect to the side central axis of the rotatable joint body.

[0009] Further, the inner dimension of the mounting groove is adapted to the outer dimension of the rubber sealing ring, and the rubber sealing ring is connected to the flange connection disc through the mounting groove.

[0010] Further, the filter assembly includes a mounting ring, a docking tenon, and a first filter screen. Docking tenons are additionally provided at the four corners of the outer part of the mounting ring, and a first filter screen is provided outside the mounting ring.

[0011] Further, the filter assembly further includes a docking mortise, an activated carbon adsorption net, and a second filter screen. Docking mortises are opened at the four corners of the rear end of the first filter screen.

[0015] 1. Through the provision of the installation component, when the easily replaceable rotary joint is in use, the limit slider can be fixedly installed at both ends inside the rotary joint body by fastening screws. At the same time, a docking ring is added outside the filter cartridge to increase the liquid flow efficiency after docking. The limit chute is used in conjunction with the limit slider to enhance the stability during the installation of the docking ring and the rotary joint body. Meanwhile, the internal dimensions of the installation groove opened on the inner side of the flange connection disc match the external dimensions of the rubber sealing ring.
