Abstract

The utility model discloses a fixed seal structure, including interior pressure disk, interior clamping ring, sealing ring, beaded finish, interior clamping ring passes through bolt and interior pressure disk fixed connection, interior clamping ring and beaded finish tip all have the step, and step surface machining becomes the sawtooth wedge, install the sealing ring between the step of interior clamping ring and beaded finish, sealing ring, interior clamping ring are passed fixed connection by the screw in proper order, the sealing ring outside is the slope form. The utility model discloses a technological effect and advantage: the novel sealing structure can increase the sealing reliability between structural members in the rotation process to the maximum extent and increase the sealing degree of the structural members to the maximum extent. The contact area between the sealing element and the sealing element can be increased to the maximum extent, the instantaneous force of the sealing element is uniformly distributed, the internal abrasion degree of the sealing element is reduced, and the reliability of the sealing element in the operation process is improved.

Description

Fixed seal structure

Technical Field

The utility model belongs to the technical field of the shedding mechanism technique of machine that mixes, the more specifically fixed seal structure that says so.

Background

At present, the sealing structure form of the pressure plate of the discharging mechanism of the mixer basically adopts a connection form that a plane is compressed by external tightening force, the structure of the connection form is simple, but the sealing reliability is not enough, and the local damage is easy to occur under the condition that the opening in the sealing piece is subjected to instantaneous force. In the production practice, the pressure plate sealing element is easy to deform and fall off due to resistance in the rotating process, so that the sealing structure is not tight, the material leakage phenomenon is generated, and the production efficiency is influenced.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above-mentioned defect of prior art, the utility model provides a fixed seal structure.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a fixed seal structure, includes interior pressure disk, interior clamping ring, sealing ring, beaded finish, interior clamping ring passes through bolt and interior pressure disk fixed connection, interior clamping ring and beaded finish tip all have the step, and step surface machining becomes the sawtooth wedge, install the sealing ring between the step of interior clamping ring and beaded finish, sealing ring, interior clamping ring are passed fixed connection in proper order by the screw, the sealing ring outside is the slope form.

The inner wall of the reinforcing ring is provided with a groove for placing a nut of the bolt.

And the bolt is sleeved with a gasket.

The utility model discloses a technological effect and advantage:

1. the novel sealing structure can increase the sealing reliability between structural members in the rotation process to the maximum extent and increase the sealing degree of the structural members to the maximum extent. The contact area between the sealing element and the sealing element can be increased to the maximum extent, the instantaneous force of the sealing element is uniformly distributed, the internal abrasion degree of the sealing element is reduced, and the reliability of the sealing element in the operation process is improved.

2. The sealing structure has the advantages that the structure between the sealing end faces is changed, under the assistance of external tightening force, the sawtooth-shaped structure of the sealing surface plays the roles of meshing, falling prevention and uniform division of instantaneous action destructive power on the sealing element, so that the sealing structure is firm and reliable, and the service life of the sealing element is prolonged.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

A fixed seal structure as shown in fig. 1 and 2, including interior pressure disk 1, interior clamping ring 2, sealing ring 3, beaded finish 4, interior clamping ring 2 passes through bolt 5 and interior pressure disk 1 fixed connection, interior clamping ring 2 and beaded finish 4 tip all have step an, and step facing becomes sawtooth wedge b, install sealing ring 3 and sticis main sealing ring between the step of interior clamping ring 2 and beaded finish 4, sealing ring 3, interior clamping ring 1 are passed fixed connection in proper order by screw 6, screw tip and interior clamping ring screw-thread fit, the sealing ring outside is like the slope form of c department.

The inner wall of the reinforcing ring is provided with a groove for placing a nut 51 of the bolt 5.

The bolt 5 is sleeved with a washer 52.

Example two

As shown in fig. 3, when the device is used in production, an external power assembly 7 for opening and closing the pressure plate is connected to the inner pressure ring 2.

The points to be finally explained are: first, in the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounted," "connected," and "connected" should be understood broadly, and may be a mechanical connection or an electrical connection, or a communication between two elements, and may be a direct connection, and "upper," "lower," "left," and "right" are only used to indicate a relative positional relationship, and when the absolute position of the object to be described is changed, the relative positional relationship may be changed;

the above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
