[0001] The utility model relates to the technical field of pipeline connection components, in particular to a high-durability high-speed rotary joint. Background Art

[0002] A rotary joint is a rotating mechanical sealing device that is used to transport and remove heat transfer media between fixed pipes and rotating rollers. Heat transfer media that can be used with rotary joints include steam, water, thermal oil, hydraulic oil, and coolant.

[0003] The rotary joints currently used do not have the impurity removal function, which makes the liquid medium easily blocked during the transportation process. Therefore, we propose a high-durability high-speed rotary joint to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the currently used rotary joints do not have the impurity removal function, which makes the liquid medium easily blocked during the transportation process, and to propose a high-durability high-speed rotary joint.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high-durability, high-speed rotary joint includes a support tube and a connecting tube. One end of the support tube is inserted into the connecting tube, and the support tube and the connecting tube are tightly fitted. The rotary joint also includes:

[0007] The filter mechanism is installed in the connecting pipe and is used to filter impurities in the heat transfer medium;

[0008] The connecting mechanism is connected to the supporting tube and the connecting tube respectively, and is used to connect the supporting tube and the connecting tube.

[0009] In one possible design, the filtering mechanism includes a clamping ring fixedly installed in the connecting pipe, a screen barrel is clamped in the clamping ring, the opening of the screen barrel is connected to the support pipe, and one end of the support pipe located in the connecting pipe is in contact with one side of the opening of the screen barrel.

[0010] In one possible design, the connecting mechanism includes a mounting ring fixedly mounted on the connecting tube, an annular groove is provided on the side of the mounting ring away from the support tube, two arc-shaped clamping plates are symmetrically slidably provided in the annular groove, one side of the arc-shaped clamping plate extends to the outside of the mounting ring and is fixedly mounted with a fixing plate, the two fixing plates are connected to the same pulling assembly, and the pulling assembly is connected to the support tube.

[0011] In one possible design, the pulling assembly includes a movable ring that is slidably mounted on a support tube, and two connecting rods are symmetrically connected to the movable ring for rotation. A positioning column is fixedly installed at one end of the connecting rod, and one end of the positioning column is fixedly connected to one side of the corresponding fixed plate.

[0012] In a possible design, two clamping seats are symmetrically fixedly mounted on the support tube, and the positioning column passes through the corresponding clamping seats and is clamped with the clamping seats.

[0013] In one possible design, a plurality of connecting plates are fixedly installed at equal intervals on one side of the movable ring, a positioning screw is connected through the connecting plate, a plurality of positioning nuts are fixedly installed at equal intervals on the support tube, and the positioning screw is threadedly connected to the corresponding positioning nuts.

[0014] In one possible design, a connecting nut is installed at one end of the support tube away from the connecting tube, and the connecting nut is used to connect to an external heat transfer medium delivery pipeline. A mounting plate is fixedly sleeved on the connecting tube, and the mounting plate is used to connect to the rotating roller. A sealing ring is fixedly installed in the connecting tube, and one side of the sealing ring extends to the outside of the connecting tube.

[0015] In the present application, the support tube is first connected to the external heat-conducting medium delivery pipe through the connecting nut, and the connecting tube is connected to the rotating roller. Then, the support tube can be inserted into the connecting tube, and then the two positioning columns are rotated so that the two arc-shaped clamping plates correspond to the position of the annular groove. Then, the two arc-shaped clamping plates can be synchronously moved into the annular groove by pulling the movable ring, so that the two arc-shaped clamping plates are clamped into the annular groove, so that the support tube and the connecting tube can be connected. After the two arc-shaped clamping plates are moved into the annular groove, the positioning screw can correspond to the position of the positioning nut. After the positioning screw is threadedly connected to the positioning nut, the movable ring can be positioned, so that the support tube and the connecting tube can be firmly connected. At this time, the connecting tube can rotate with the rotating roller without affecting the normal flow of the heat-conducting medium. At the same time, when the heat-conducting medium passes through the screen barrel, the impurities in the heat-conducting medium can be filtered, so that the heat-conducting medium will not be blocked during flow, and when the support tube and the connecting tube are separated and disassembled, the screen barrel can be taken out so that the filtered impurities can be cleaned.

[0016] Beneficial effects:

[0017] In the utility model, the high-durability high-speed rotary joint can be provided with a screen barrel in the connecting pipe through the filtering mechanism, which can conveniently filter impurities in the heat-conducting medium passing through the support pipe and the connecting pipe, thereby preventing the heat-conducting medium from being blocked during flow. Moreover, when the support pipe and the connecting pipe are separated and disassembled, the screen barrel can be taken out to clean the filtered impurities.

[0018] In the utility model, the high-durability high-speed rotary joint is characterized by a connection mechanism. When the two arc-shaped clamping plates are aligned with the annular groove, the pulling assembly can be pulled to synchronously move the two arc-shaped clamping plates into the annular groove to achieve clamping with the mounting ring, thereby stably connecting the support pipe and the connecting pipe. At the same time, the arc-shaped clamping plates can slide circumferentially in the annular groove, so as not to affect the mutual rotation between the support pipe and the connecting pipe.

[0019] The support tube and the connecting tube of the utility model can be rotated and used normally after being connected, and the heat-conducting medium can be filtered when passing through the support tube and the connecting tube, so that impurities in the heat-conducting medium can be filtered out, thereby preventing the problem of blockage in actual use, and the filtered impurities can be easily cleaned, so it has good practicality.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The two fixing plates 9 are connected to the same pulling component, and the pulling component is connected to the supporting tube 1. When the two arc-shaped clamping plates 10 are aligned with the annular groove, the pulling component can be pulled to synchronously move the two arc-shaped clamping plates 10 into the annular groove to achieve clamping with the mounting ring 5, so that the supporting tube 1 and the connecting tube 2 can be stably connected. At the same time, the arc-shaped clamping plate 10 can slide circumferentially in the annular groove, so it will not affect the mutual rotation between the supporting tube 1 and the connecting tube 2. The pulling component includes a moving ring 6 slidingly sleeved on the supporting tube 1. The moving ring 6 is symmetrically connected to two connecting rods 7, one end of the connecting rod 7 is fixedly installed with a positioning column 8, and one end of the positioning column 8 is fixedly connected to one side of the corresponding fixed plate 9.

Two clamping seats 11 are symmetrically fixedly installed on the support tube 1, and the positioning column 8 passes through the corresponding clamping seat 11 and is clamped with the clamping seat 11. After the positioning column 8 is moved to a horizontal position, it can correspond to the opening position on the clamping seat 11, and after the positioning column 8 is moved to be clamped with the clamping seat 11, the positioning column 8 can be limited at this time, so that the arc-shaped clamping plate 10 can be stably connected to the annular groove.
