Description
Technical Field
The utility model belongs to the technical field of transfer devices, and particularly relates to a sealing structure capable of automatically adjusting and adding fillers.
Background
In industrial production, operation equipment such as various types of fans, water pumps and the like are very widely used, most of sealing structures adopted by the fans and the water pumps are filled with sealing materials, the sealing materials are worn in the long-term operation process, personnel are required to maintain and replace the sealing materials, damaged sealing materials are difficult to take out during replacement, and labor intensity of workers and maintenance cost of the sealing structures are increased. FIG. 1 is a layout of a conventional packing, the packing being located in a cavity between a housing and a shaft, the housing outer end being connected to a gland for compressing the packing; the sealing filler is clamped in the cavity and is difficult to take out because the shell and the shaft cannot be detached.
Disclosure of Invention
The utility model provides a sealing structure capable of automatically adjusting added filler, and aims to solve the problem that conventional sealing filler is difficult to replace after being worn.
Therefore, the utility model adopts the following technical scheme:
the sealing structure comprises a sealing sleeve horizontally and fixedly connected to the head end of a rotating shaft, wherein the inner cavity of the sealing sleeve is cylindrical and forms a sealing cavity, the inner diameter of the sealing cavity is larger than the diameter of the rotating shaft, the tail end of the sealing cavity is provided with a central hole matched with the rotating shaft, and the head end of the sealing cavity is in an open shape;
the bottom of the sealing cavity is provided with a spring, a cylindrical pressing sleeve is sleeved on the spring, one end of the spring abuts against the bottom surface of the sealing cavity, the other end of the spring abuts against the pressing sleeve, and the spring can push the pressing sleeve to slide along the inner wall of the sealing cavity; a plurality of sealing fillers are sleeved in the sealing cavity at the front side of the pressing sleeve; the head end of the sealing cavity is connected with a gland, and the head end of the gland stretches into the sealing cavity to press the sealing filler.
Further, a first flange is arranged in the middle of the outer ring of the sealing sleeve, and a second flange is arranged at the head end of the outer ring of the sealing sleeve; the first flange is connected with the equipment shell, and the second flange is connected with the gland.
Further, a sealing gasket is arranged between the contact surface of the first flange plate and the equipment shell.
Further, the gland is of a two-flap structure.
The packing is tightly sealed through the spring top, so that the structure is always in a high-efficiency sealing state; when the sealing filler is replaced, the gland is taken down, the sealing filler can be ejected out of the sealing cavity under the action of the spring, the problem that the original sealing filler can not be taken out when being clamped in the sealing cavity is solved, and the replacement operation of the sealing filler is greatly facilitated.

FIG. 2 is a schematic illustration of an improved seal configuration of the present utility model;
in the figure: 1-equipment shell, 2-first bolt, 3-spring, 4-compression sleeve, 5-second bolt, 6-pivot, 7-gland, 8-packing, 9-sealing sleeve, 10-gasket.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
as shown in fig. 2, the sealing structure capable of automatically adjusting the filling material is characterized by comprising a sealing sleeve 9 horizontally and fixedly connected to the head end of a rotating shaft 6, wherein the inner cavity of the sealing sleeve 9 is cylindrical and forms a sealing cavity, the inner diameter of the sealing cavity is larger than the diameter of the rotating shaft 6, the tail end of the sealing cavity is provided with a central hole matched with the rotating shaft 6, and the head end of the sealing cavity is in an open shape.
The bottom of the sealing cavity is provided with a spring 3, a cylindrical pressing sleeve 4 is sleeved on the spring 3, one end of the spring 3 abuts against the bottom surface of the sealing cavity, the other end abuts against the pressing sleeve 4, and the spring 3 can push the pressing sleeve 4 to slide along the inner wall of the sealing cavity; a plurality of sealing fillers 8 are sleeved in the sealing cavity at the front side of the pressing sleeve 4; the head end of the sealing cavity is connected with a gland 7, and the head end of the gland 7 extends into the sealing cavity to press the sealing filler 8. For convenient disassembly, the gland 7 has a two-flap structure and is respectively connected with the equipment shell 1.
The middle part of the outer ring of the sealing sleeve 9 is provided with a first flange, and the head end of the outer ring of the sealing sleeve 9 is provided with a second flange; the first flange is connected with the equipment shell 1 through a first bolt 2, and the second flange is connected with the gland 7 through a second bolt 5. A sealing gasket 10 is arranged between the contact surface of the first flange plate and the equipment housing 1.
Through multiple practices, the sealing device capable of being automatically adjusted is invented in order to realize long-period continuous operation of equipment and ensure continuous production. The device installs the sealing packing 8 in the detachable sealing cavity, and the spring 3 is arranged in the sealing cavity, and the packing is always in a compressed state under the action of the spring 3 in the running process of the device, so that the service cycle of the packing can be greatly prolonged, the packing is damaged, and the packing can be easily replaced.
