Description

Technical Field

[0001] This utility model relates to the field of steam dryers, and in particular to a steam dryer coil. Background Technology

[0002] The coil is installed on the dryer. The two main pipes of the existing coil need to be sealed at the panel at the tail of the dryer to prevent dust leakage. The existing technology is to first apply sealant to the sealing base plate, put it on the main pipe of the coil and fit it tightly against the panel at the tail of the dryer, then install the sealing pressure ring and flange pressure plate, use the sealing pressure ring to compact the sealant, and finally use bolts to press the flange pressure plate tightly onto the sealing pressure ring to achieve the sealing effect.

[0003] However, during the operation of the steam dryer, the coil experiences weightlessness and swaying as it moves downwards, causing the main coil pipe to sway as well. Since the main coil pipe is supported by a sealing structure at the rear of the panel, if the coil experiences significant swaying during long-term operation, the sealing ring may loosen, and the lower sealant may even fail, leading to dust leakage. Utility Model Content

[0006] In a preferred embodiment, the buffer device includes a collar mounted on the main coil, buffer rods evenly distributed around the outer side of the collar, a first mounting hole provided in the axial direction of the buffer rods, a spring and a top ball provided in the first mounting hole, the top ball being located at the front end of the spring, and during operation, the top ball pressing against the inner wall of the through hole.

[0007] In a preferred embodiment, a flange is provided at the front end of the first mounting hole, and the diameter of the hole formed by the flange is smaller than the diameter of the top ball; a threaded hole is provided at the rear end of the mounting hole, and a set screw is provided in the threaded hole.

[0008] In a preferred embodiment, a second mounting hole is provided on the collar, the buffer rod passes through the second mounting hole and is welded together, and the bottom of the buffer rod is flush with the inner diameter of the collar.

[0009] In the preferred embodiment, a flange pressure plate is fitted onto the main steam coil outside the sealing sleeve, and bolts are inserted through the flange pressure plate. The inner end of the bolts is threaded into the tail panel of the dryer, and the flange pressure plate is pressed onto the outer end face of the sealing sleeve.

Detailed Implementation

[0020] Please see Figure 1-5 As shown, this application provides a technical solution: a steam dryer coil, including a main coil 11, a through hole 121 on the tail panel 12 of the dryer, the main coil 11 passing through the through hole 121, a sealing sleeve 13 between the main coil 11 and the through hole 121, the sealing sleeve 13 tightly fitting the outer wall of the main coil 11 and the inner wall of the through hole 121, and a buffer device 2 between the main coil 11 and the through hole 121.

[0021] The sealing sleeve 13 can be configured as an L-shaped annular structure, with the larger diameter side of the sealing sleeve 13 installed above the through hole 121, so that the sealing sleeve 13 is not easy to fall off.

[0022] In a preferred embodiment, the buffer device 2 includes a collar 21 mounted on the main coil 11, buffer rods 22 evenly distributed around the outer side of the collar 21, a first mounting hole 221 provided in the axial direction of the buffer rods 22, a spring 23 and a top ball 26 provided in the first mounting hole 221, the top ball 26 being located at the front end of the spring 23, and during operation, the top ball 26 pressing against the inner wall of the through hole 121.

[0023] In this way, one end of the buffer device 2 rests in the through hole 121 of the rear panel 12 of the dryer, and the other end rests on the coil. When the main coil 11 encounters a large shaking, the main coil 11 shakes and squeezes the top ball 26, the top ball 26 compresses the spring 23, and the spring 23 absorbs the energy of the shaking, thereby reducing the shaking of the main coil 11. In this way, the shaking of the sealing mechanism is reduced, thereby improving the service life of the sealing mechanism.

[0024] In a preferred embodiment, a flange 24 is provided at the front end of the first mounting hole 221, and the diameter of the hole formed by the flange 24 is smaller than the diameter of the top ball 26; a threaded hole is provided at the rear end of the mounting hole 221, and a set screw 25 is provided in the threaded hole.

[0025] The set screw 25 can rotate to compress the spring 23, thereby increasing the preload of the spring 23 on the top ball 26.

[0026] Since the aperture formed by the flange 24 is smaller than the diameter of the top ball 26, the top ball 26 will not pop out of the first mounting hole 221.

[0027] In a preferred embodiment, a second mounting hole 211 is provided on the collar 21, and the buffer rod 22 passes through the second mounting hole 221 and is welded together, with the bottom of the buffer rod 22 flush with the inner diameter of the collar 21.

[0028] In a preferred embodiment, a flange plate 14 is fitted onto the main steam coil 11 outside the sealing sleeve 13, and a bolt 15 is inserted through the flange plate 14. The inner end of the bolt 15 is threaded into the tail panel 12 of the dryer, and the flange plate 14 is pressed onto the outer end face of the sealing sleeve 13.

[0029] In the preferred embodiment, a sealing ring 16 is provided between the flange pressure plate 14 and the sealing sleeve 13.

[0030] In the preferred embodiment, the sealing sleeve 13 and the sealing ring 16 are made of fluororubber.

[0031] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
