Description

Technical Field

[0001] This utility model relates to the field of rotary joint technology, and particularly to rotary joints. Background Technology

[0002] A rotary joint is a sealed rotary connector that rotates 360° to transport media. It is used to transport fluid media from fixed pipelines to rotating or oscillating pipeline equipment, achieving dynamic sealing to prevent media leakage.

[0003] In the existing technology, the rotary joint for cooling the main shaft of a granulator, application number CN202320489477.5, uses a cooler to cool the water in the water tank, and then uses a water pump to draw the water out of the water tank and discharge it into the chamber. When the chamber is full of water, it enters the spiral hole through the inlet, which can cool the joint body and thus improve the service life of the joint body. However, the position of the joint body is relatively fixed. After the medium pipeline and equipment are installed, when connecting the medium pipeline and equipment through the rotary joint, if there is a certain deviation in the distance between the medium pipeline and the equipment, it is not convenient to adjust the axial distance of the rotary joint. It is necessary to remeasure the distance and reinstall the pipeline, resulting in low work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a rotary joint that can solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rotary joint, including a joint body: An adjustment component, installed inside the joint body, is used to adjust the axial length of the rotary joint; The adjustment component includes: A sliding connecting pipe is installed inside the connector body. A stabilizing ring is rotatably connected to the outside of the connecting pipe via a bearing. A connecting column is fixedly installed on the left side of the stabilizing ring. An adjusting ring is fixedly installed on the left side of the connecting column. An adjusting nut is threaded to the front and rear ends of the adjusting ring. A limit plate is rotatably connected to the adjusting nut near the central axis. A rubber pad is adhered to the limit plate near the central axis.

[0006] In the above scheme, rotating the adjusting nut causes the limiting plate to slide, causing the rubber pad on the limiting plate to disengage from the joint body, thereby releasing the locking of the adjusting ring. Then, the adjusting ring is slid, and through the cooperation of the connecting column and the stabilizing ring, the connecting pipe is pushed to slide, thereby realizing the position adjustment of the connecting pipe.

[0007] A further feature of this invention includes: A cooling assembly, installed inside the connector body, is used to dissipate heat and cool the rotary connector.

[0008] The cooling assembly includes: A cooling pipe is fixedly installed inside the connector body. An inlet pipe is fixedly installed at the upper end of the cooling pipe. A filter box is fixedly installed at the upper end of the inlet pipe. A filter frame is slidably connected inside the filter box. A filter screen is installed inside the filter frame.

[0009] In the above scheme, the cooling medium is introduced into the filter box and enters the cooling pipe through the liquid inlet pipe to achieve cooling and heat dissipation inside the connector body.

[0010] A further feature of this invention includes: A locking component, which is installed inside the cooling component, is used to lock the internal structure of the cooling component.

[0011] The locking component includes: A locking block is fixedly installed at the front and rear ends of the filter box. A locking block is slidably connected inside the locking block. A spring is provided between the locking block and the locking block. A pull rod is fixedly installed on the side of the locking block away from the central axis. The upper end of the side of the locking block near the central axis is designed with a slope.

[0012] In the above solution, pulling the lever causes the locking block to slide, allowing the locking block to slide away from the upper end of the filter frame, thus releasing the lock on the filter frame and facilitating the installation and disassembly of the filter frame.

[0013] The beneficial effects of this utility model are: The adjustment component of this utility model, through the cooperation of the connecting column and the adjustment ring, facilitates the adjustment of the axial position of the connecting pipe, so that the rotary joint can still be adjusted and installed even when there is a certain distance between it and the pipes on both sides, without affecting the installation of the rotary joint. At the same time, the cooling component, through the cooperation of the cooling pipe and the filter frame, realizes the cooling and heat dissipation of the internal structure of the joint body, avoids overheating and damage to the internal structure of the joint body, and prevents impurities from entering the cooling pipe and causing blockage, thus affecting the cooling and heat dissipation of the joint body.

[0014] The locking component of this invention uses a locking block and a pull rod to facilitate the disassembly of the filter frame and the cleaning and replacement of the filter screen, while ensuring the stability of the filter frame after installation. Attached Figure Description

[0018] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] Reference Figure 1-4 The rotary joint includes a joint body 1, an adjustment component 2, a cooling component 3, and a locking component 4. The adjustment component 2 is installed inside the joint body 1 and is used to adjust the axial length of the rotary joint. The cooling component 3 is installed inside the joint body 1 and is used to dissipate heat and cool the rotary joint. The locking component 4 is installed inside the cooling component 3 and is used to lock the internal structure of the cooling component 3.

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The adjusting component 2 includes: a connecting pipe 201 slidably connected inside the connector body 1; a stabilizing ring 202 rotatably connected to the outside of the connecting pipe 201 via a bearing; a connecting column 203 fixedly installed on the left side of the stabilizing ring 202; an adjusting ring 204 fixedly installed on the left side of the connecting column 203; adjusting nuts 205 threadedly connected to the front and rear ends of the adjusting ring 204; a limiting plate 206 rotatably connected to the adjusting nut 205 near the central axis; and a rubber pad 207 adhered to the limiting plate 206 near the central axis. The cooling component 3 includes: a cooling pipe 301 fixedly installed inside the connector body 1; an inlet pipe 302 fixedly installed at the upper end of the cooling pipe 301; a filter box 303 fixedly installed at the upper end of the inlet pipe 302; a filter frame 304 slidably connected inside the filter box 303; and a filter screen 305 disposed inside the filter frame 304.

[0021] In this invention, when there is a certain deviation in the axial distance between the pipes on both sides of the rotary joint, rotating the adjusting nut 205 causes the limiting plate 206 to slide outward, thereby causing the rubber pad 207 to disengage from the joint body 1 and releasing the locking of the adjusting ring 204. Then, sliding the adjusting ring 204 causes the connecting column 203 to slide, which in turn causes the stabilizing ring 202 to slide. The stabilizing ring 202 then pushes the connecting pipe 201 to slide, thus adjusting the axial position of the connecting pipe 201. This facilitates the connection between the connecting pipe 201 and the pipe, and allows for adjustment of the axial position of the connecting pipe 201. This ensures that the rotary joint can still be adjusted and installed even when there is a certain distance between it and the pipes on both sides, avoiding interference with the installation of the rotary joint and improving work efficiency. After the connecting pipe 201 slides to the designated position, rotating the adjusting nut 205... 5. Push the limiting plate 206 to slide, so that the rubber pad 207 on the limiting plate 206 fits against the connector body 1, thereby locking the adjusting ring 204 and locking the connecting pipe 201. When it is necessary to cool the inside of the connector body 1, input the filter medium into the pipe on the filter box 303, so that the filter medium enters the inlet pipe 302 through the filter box 303, and then flows into the cooling pipe 301, thereby cooling the inside of the connector body 1, avoiding overheating damage to the internal structure of the connector body 1, and improving the service life of the rotary joint. At the same time, the filter screen 305 on the filter frame 304 inside the filter box 303 filters the cooling medium, preventing impurities from entering the cooling pipe 301 and preventing the accumulation of impurities inside the cooling pipe 301 from causing blockage and affecting the cooling of the connector body 1.

[0022] Reference Figure 1 and Figure 4 The locking component 4 includes: a locking block 401 fixedly installed at the front and rear ends of the filter box 303; a locking block 402 slidably connected inside the locking block 401; a spring 403 between the locking block 402 and the locking block 401; a pull rod 404 fixedly installed on the side of the locking block 402 away from the central axis; and the upper end of the side of the locking block 402 near the central axis is designed with a slope.

[0023] In this invention, when the filter screen 305 on the filter frame 304 is used for a long time, a certain amount of impurities will accumulate on its surface. At this time, pulling the lever 404 will cause the locking block 402 to slide into the locking block 401, so that the locking block 402 disengages from the upper end of the filter frame 304 and presses the spring 403, thereby releasing the lock on the filter frame 304. Then, the filter frame 304 is pulled to the right to remove the filter frame 304 from the filter box 303, thus disassembling the filter frame 304, which facilitates the cleaning and replacement of the filter screen 305, while ensuring the stability of the filter frame 304 after installation.
