The inlet and outlet steam pipes are installed with highly flexible metal hoses, and the lower auxiliary support is fixed at both ends by connecting rod welding.
[0003] However, since the center of the steam rotary joint and the rotating cylinder cannot be truly concentric, the rotary joint seal will inevitably wear out; the lower auxiliary support connecting rod is fixed and welded, which affects the free adjustment and compensation of the rotary joint.

The delivery cycle is long, the accessories are expensive, the investment capital is high, the labor intensity is high during replacement, and the operation risk is high, which affects the long-term safe and stable operation of the coal slime dryer.

DETAILED DESCRIPTION
[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0024] According to an embodiment of the utility model, a rotary joint fixing device is provided. Figure 1 to Figure 2 , including: a device body 10, the device body 10 is rotatably connected to the rotary joint 100; an adjusting plate 20, the adjusting plate 20 is fixedly arranged, and the device body 10 passes through the adjusting plate 20; an adjusting spring 30, the adjusting spring 30 is passed through the device body 10; a stopper 40, the stopper 40 is sleeved on the device body 10, one end of the adjusting spring 30 abuts against the adjusting plate 20, and the other end of the adjusting spring 30 abuts against the stopper 40.
[0025] Specifically, the rotary joint includes a rotation center and an outer cylinder mounted outside the rotation center. The device body 10 is rotatably connected to the outer cylinder of the rotary joint 100. By providing a lifting device at the upper end of the rotary joint 100 and installing the rotary joint fixing device in this embodiment at the lower end of the rotary joint 100, auxiliary fixing of the rotary joint 100 can be achieved.
[0026] By setting a rotary joint fixing device and compressing and releasing the adjusting spring 30, the device body 10 can float back and forth along the extension direction of the device body 10. When the dryer is started or the steam parameters change, the outer cylinder of the rotary joint jumps too much, and the device body 10 can move along the direction and magnitude of the stress to achieve free adjustment and stress compensation, and effectively release the stress carried by the outer cylinder of the rotary joint, thereby reducing the mutual friction between the rotation center of the rotary joint and the rotating outer cylinder, avoiding damage to the sealing material inside the rotary joint 100, reducing the operational risk of replacing accessories, and ensuring safe and stable long-term operation of the dryer. In addition, one end of the rotary joint fixing device is connected to the outer cylinder, and the other end is connected to the adjusting plate 20, which can prevent the outer cylinder from rotating uncontrollably, avoid the steam pipes from being entangled with each other and the occurrence of rotary joint spare parts loss, further avoid frequent replacement of rotary joints, and solve the technical problem in the related art that the stress of the rotary joint cannot be effectively released when the coal slime dryer is started or the steam parameters change.
[0027] In the rotary joint fixing device of this embodiment, see Figure 2 The device body 10 includes a connection part 1 connected to the rotary joint 100, and the connection part 1 includes: a connection shaft 11, the extension direction of the connection shaft 11 is consistent with the extension direction of the rotary joint 100, and the connection shaft 11 is rotatably connected to the pin 503 located on the rotary joint 100; a connection rod 12, the extension direction of the connection rod 12 is perpendicular to the extension direction of the connection shaft 11, and the two ends of the connection rod 12 are respectively connected to the connection shaft 11 and the device body 10. In this way, the rotatable connection between the device body 10 and the rotary joint 100 is realized, so that the device body 10 can float back and forth following the stress.
[0028] In the rotary joint fixing device of this embodiment, see Figure 1 The adjusting plate 20 includes a mounting hole 201, and the device body 10 includes an adjusting rod 2, and the adjusting rod 2 is inserted into the mounting hole 201. Through the above arrangement, the adjusting plate 20 is fixedly arranged in the device to stop the adjusting spring 30, and the adjusting rod 2 is inserted into the mounting hole 201 so that the adjusting rod 2 can reciprocate.
[0029] In the rotary joint fixing device of this embodiment, see Figure 1 The adjusting rod 2 is provided with an external thread, the stopper 40 is provided with an internal thread, and the stopper 40 is threadedly connected with the adjusting rod 2. Through the above arrangement, the stopper 40 is movably connected with the adjusting rod 2, and the elastic force of the adjusting spring 30 can be adjusted by adjusting the position of the stopper 40.
[0030] In the rotary joint fixing device of this embodiment, see Figure 1The device body 10 includes a driving component 3, the extended end of the driving component 3 is retractable, the extended end of the driving component 3 is fixedly connected to the adjustment rod 2, and the end of the driving component 3 away from the extended end is connected to the connecting portion 1. By setting the driving component 3, according to the tension applied to the device body 10, the extended end of the driving component 3 can be controlled to extend or retract, so as to dynamically adjust the distance between the connecting portion and the adjustment plate 20, so that the tension of the device body 10 is kept within a reasonable range, and further avoid the sealing material inside the rotary joint 100 from being damaged.
[0031] Specifically, the driving component 3 includes but is not limited to a driving cylinder such as an electric push rod and an oil cylinder.
[0032] In the rotary joint fixing device of this embodiment, see Figure 1 The device body 10 includes a tension detection device 4, one end of which is connected to the connection part 1, and the other end of which is connected to the driving component 3. By setting the tension detection device 4, the tension applied to the device body 10 can be detected and fed back in real time, so that the driving component 3 can achieve dynamic adjustment.
[0033] Specifically, when the pulling force exceeds a certain value, the outer cylinder of the rotary joint jumps in a direction away from the rotary joint fixing device. At this time, the driving component 3 is controlled to extend, so that the overall length of the device body 10 is lengthened, the pulling force on the device body 10 is reduced, and the mutual friction between the rotation center of the rotary joint and the rotating outer cylinder is reduced. When the outer cylinder of the rotary joint jumps in a direction close to the rotary joint fixing device, the driving component 3 is reset or maintained in the initial state, and the stress compensation is achieved by compressing the adjustment spring 30.

Through the above arrangement, the rotation connection between the device body 10 and the rotary joint is realized, and the rotary joint 100 can be prevented from uncontrollable rotation.
[0035] Preferably, the fixing seat 50 is disposed at the lower end of the outer cylinder of the rotary joint 100 .

The fixed seat 50 in this embodiment can be installed at the lower end of the rotating joint 100 and the extension direction of the device body 10 is perpendicular to the gravity direction of the rotating joint 100 to compensate and adjust the stress on the rotating joint in the horizontal direction.
