[0011] 1) The packing gland is arranged on the sealing port of the hydrator body, the bushing is arranged on the outer shell of the feeding auger, the graphite packing ring is filled between the bushing and the packing gland, the graphite packing ring is compressed by the sealing gland, and thus the feeding auger and the hydrator body are well sealed.

[0012] 2) The annular protrusion is arranged on the side of the sealing gland facing the packing gland, the compression surface is arranged on the side of the annular protrusion facing the sealing packing, the annular protrusion compresses the graphite packing ring through the compression surface, and the compression surface is gradually inclined from the small-diameter side to the large-diameter side to the direction of the sealing packing, so that the graphite packing ring is tightly attached to the bushing, and the sealing property between the graphite packing ring and the bushing is improved. BRIEF DESCRIPTION OF DRAWINGS

[0013] ATTACHED Figure 1 It is a structure diagram of the hydrator sealing device. DETAILED DESCRIPTION

[0014] The hydrator sealing device will be further described below with reference to the drawings.

[0015] As shown in the drawings, Figure 1 The hydrator sealing device comprises a hydrator body 1 and a feeding auger 2, the feeding end of the hydrator body 1 is provided with a sealing port 3, and the feeding auger 2 is inserted into the sealing port 3 of the hydrator body 1. The outer side of the sealing port 3 of the hydrator body 1 is connected with an annular packing gland 4, and the packing gland 4 is fixed at the sealing port 3 of the hydrator body 1 by welding. An annular cavity is formed between the packing gland 4 and the feeding auger 2, and sealing packing is arranged in the annular cavity. Specifically, the sealing packing is a graphite packing ring 5.

[0016] The end of the packing gland 4 away from the hydrator body 1 is an open end, the graphite packing ring 5 can be arranged between the packing gland 4 and the feeding auger 2 from the open end, and a detachable sealing gland 6 is arranged on the open end to compress the graphite packing ring 5, so that the sealing port 3 of the hydrator body 1 and the feeding auger 2 are well sealed.

[0017] The bushing 9 is arranged on the outer shell of the feeding auger 2, and the graphite packing ring 5 is arranged between the packing gland 4 and the bushing 9. Specifically, the outer shell of the feeding auger 2 is polished, and then the bushing 9 is welded on the outer shell of the feeding auger 2. As shown in the drawings, Figure 1 The width of the bushing 9 is greater than that of the packing gland 4, one end of the bushing 9 extends into the sealing port 3, and the other end of the bushing 9 extends out of the sealing gland 6.

[0018] The annular protrusion 7 is inserted into the packing gland 4 from the open end of the packing gland 4, and the annular protrusion 7 correspondingly extrudes the graphite packing ring 5 to press the graphite packing ring 5 tightly in the packing gland 4, so that the graphite packing ring 5 is tightly attached to the bushing 9 of the feed auger 2, and the sealing performance is enhanced.

[0019] The side of the annular protrusion 7 towards the graphite packing ring 5 is a pressing surface 8. Figure 1 As shown in the drawings, the pressing surface 8 is gradually inclined from the small-diameter side to the large-diameter side towards the graphite packing ring 5, that is, the pressing surface 8 is a concave tapered surface. Therefore, the pressing effect of the annular protrusion 7 on the outer ring portion of the graphite packing ring 5 is greater than that on the inner ring portion, and under this difference, the graphite packing ring 5 is extruded towards the bushing 9, so that the graphite packing ring 5 is more tightly attached to the bushing 9, and the sealing performance is further improved.

[0020] The open end of the packing gland 4 is provided with a surrounding edge 11, and the sealing cover 6 is tightly attached to the surrounding edge 11, and the sealing cover 6 and the surrounding edge 11 are fixedly connected by the locking bolt 10. When the locking bolt 10 is removed, the sealing cover 6 can also be removed from the open end of the packing gland 4, so as to load the graphite packing ring 5 or take out the graphite packing ring 5.

[0021] The front sealing assembly of the existing hydrator body 1 needs to be replaced many times within one year. Even if a new sealing assembly is installed, the phenomenon of running, leaking and dripping still occurs during operation when positive pressure occurs. When the sealing assembly is replaced, it is not convenient to replace due to the small maintenance space, and it is time-consuming and laborious.

[0022] The sealing device of the graphite packing ring 5 type in the utility model needs only to replace the graphite packing ring 5, is convenient to maintain, and requires less time to complete the replacement work. The sealing device has good sealing performance, can completely eliminate the running, leaking and dripping phenomenon of the hydrator, improves the on-site environment, reduces the labor amount of maintenance personnel and operators, and can better control the process indicators

[0023] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary technical personnel in the technical field, some improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model.
