Problems solved by technology

When working, the sealing effect is determined by the tightness of the joint surface between the inner side of the sealing packing and the rotating shaft, and the axial pressing force applied from the outside is transmitted inward layer by layer through the deformation of the extrusion sealing packing, so that the inner side of the sealing packing hugs the rotating shaft and engages The pressing force of the surface will gradually attenuate, which will greatly reduce the use effect of the sealing device

Embodiment Construction

[0024] In the following, the present invention will be further clarified in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, those skilled in the art will give various equivalents to the present invention. All the modifications fall within the scope defined by the appended claims of this application.

[0025] Such as Figure 1-3 As shown, a thermal compression sealing device includes a sealing seat 5 arranged on the conditioner housing 1 and a rotating shaft 9 movably sleeved in the center of the sealing seat 5. The outer wall of the rotating shaft 9 and the inner wall of the sealing seat 5 are compressed There is a sealing packing 6. The outer end of the sealing seat 5 is provided with a gland 8 that compresses the outer surface of the sealing packing 6, and the outer end of the sealing packing 6 is set a...

Abstract

The invention discloses a thermal force compression sealing device in the technical field of shaft end sealing structures. The device comprises a sealing seat arranged on a conditioning device shell and a rotating shaft movably arranged at the center of the sealing seat in a sleeving mode, a sealing filler is pressed between the outer wall of the rotating shaft and the inner wall of the sealing seat, the outer side end of the sealing seat is provided with a gland for pressing the outer side face of the sealing filler, the inner side end of the sealing seat extends into the conditioning deviceshell and is provided with a sealing groove, a groove opening of the sealing groove is provided with a movable gland for compressing the inner side face of the sealing filler, the movable gland is circumferentially positioned on the sealing seat and can move axially along the sealing seat, and an internal hollow sealing cavity structure is formed between the movable gland and the sealing groove. The thermal force compression sealing device has the advantages that it is ensured that the rotating shaft are tightly pressed through the inner side and the outer side of the sealing filler at the same time, and therefore, the device is suitable for sealing of the rotating shaft end of a feed conditioning device, and the sealing effect is improved.

Description

Technical field [0001] The invention relates to the technical field of shaft end sealing structures, in particular to a thermal compression sealing device. Background technique [0002] The conditioner is a key equipment in the production process of food, feed, grain and oil industries, and its conditioning process is that the heat and quality of the gas phase substance (steam) and the liquid phase substance (the moisture of the condensed steam and the added moisture) are transferred to the solid phase substance ( The process of transferring heat and quality of powdery materials is a process in which the heat and quality in the steam are transferred to the inside through the outer surface of the powdery particles. During the quenching and tempering process, the sealing requirements for the conditioner are high, and leakage of materials and air leakage is not allowed. The existing quenched and tempered shaft end seal generally adopts a single packing structure, and leakage or wat...
