Description

Technical Field

[0001] This invention relates to the field of rotary drum joint technology, specifically a four-medium combined rotary joint for rotary drums. Background Technology

[0002] The rotary joint used for the drum is a pipeline connection device, and the connected pipelines can rotate relative to each other. It can be used to convey various media such as gas, liquid, and oil. Its compact design structure and flange connection make it effectively integrated into the drum.

[0003] Due to the requirements of the drum function, it is necessary to simultaneously supply water, electricity, steam and compressed air to the drum. Single-medium rotary joints are available on the market, but ordinary drum joints cannot supply four media at the same time, and cannot meet the requirement of simultaneous supply of four media.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-2 The four-medium combined rotary joint for a drum in this embodiment includes a drum rotating part, a rotating shaft seat 3 and a fixing part;

[0032] The rotating part of the drum includes a drum connecting plate 1 and a drum connecting seat 2, with the left side of the drum connecting seat 2 connected to the right side of the drum connecting plate 1;

[0033] The bearing housing 3 is sleeved on the outside of the right side of the drum connecting seat 2 to support the drum connecting seat 2, so that the rotating part of the drum can rotate evenly.

[0034] The fixing part 3 includes a water connector structure 4, a steam connector structure 5, an electrical wire connector structure 6, and an air connector structure 7. The four media connector structures can respectively convey media to the inside of the drum through the rotating part of the drum.

[0035] The water connector structure 4 includes a shaft tube 41 and a water screw connector 42. The shaft tube 41 passes through the right side of the drum connecting seat 2 and the drum connecting plate 1, and is flush with the left side of the drum connecting plate 1. The right side of the shaft tube 41 is equipped with a water screw connector 42. As the most important connector structure for the water medium, the shaft tube 41 has a long tube design that facilitates the assembly of other structures and provides support contact. The shaft tube 41 passes directly through to the left side of the rotating part of the drum for easy water supply. When connected with the water screw connector 42, it can also rotate relative to the shaft tube 41.

[0036] The steam connector structure 5 includes a steam pipe 51 and a steam screw connector 52. The steam pipe 51 extends from the left side of the shaft pipe 41 to the right side of the water screw connector 42. The steam screw connector 52 is installed on the right side of the steam pipe 51. The opposite side of the steam pipe 51 and the steam screw connector 52 extends directly into the inside of the shaft pipe 41 and connects. Steam is directly transported using the internal space of the shaft pipe 41 without interfering with the transport of water. With the help of the steam screw connector 52, the steam pipe 51 can rotate relative to each other.

[0037] The air connector structure 7 includes a multi-channel compressed air rotary joint 71 and a multi-channel compressed air pipe 72. The multi-channel compressed air rotary joint 71 is sleeved on the outside of the shaft tube 41. The multi-channel compressed air pipe 72 is assembled on the left side of the multi-channel compressed air rotary joint 71. The multi-channel compressed air pipe 72 extends to the top of the drum connecting seat 2 through the perforation at the top. The sealing plate serves as a limiting and sealing base, and works with the compressed air rotary joint 71 to allow the multi-channel compressed air pipe 72 to rotate relative to it.

[0038] The wire connector structure 6 includes a multi-channel electrical rotary connector 61 and a multi-channel electrical conduit 62. The multi-channel electrical rotary connector 61 is sleeved on the outside of the shaft tube 41. The multi-channel electrical rotary connector 61 is equipped with the multi-channel electrical conduit 62. The multi-channel electrical conduit 62 extends to the bottom of the drum connecting seat 2 through a perforation at the bottom. The sealing plate serves as a limiting and sealing base and works in conjunction with the multi-channel electrical rotary connector 61 to allow the multi-channel electrical conduit 62 to rotate relative to it.

[0039] The working principle of the above embodiments is as follows:

[0040] (1) The shaft tube 41 provides an assembly base for the wire connector structure 6 and the air connector structure 7. The wire connector structure 6 and the air connector structure 7 can be configured with rotating bases for the multi-channel wire conduit 62 and the multi-channel compressed air conduit 72 respectively through the multi-channel electric rotary joint 61 and the multi-channel compressed air rotary joint 71. The multi-channel wire conduit 62 and the multi-channel compressed air conduit 72 can respectively realize the transportation of electrical medium and compressed air medium.

[0041] (2) The shaft tube 41 uses the water screw joint 42 to supply water in and out, pumping sufficient water into the inside of the drum. The steam joint structure 5 inside the shaft tube 41 uses the steam pipe 51 and the steam screw joint 52 to allow steam to pass through the steam pipe 51 from the steam screw joint 52 and be transported to the inside of the drum. Through the combination of the above four joint structures, the transportation of the four media is integrated into one, achieving the purpose of one thing serving multiple purposes.
