Description
Technical Field
The utility model belongs to the technical field of the cone crusher, concretely relates to multi-cylinder cone crusher seal structure that prevents dust.
Background
The multi-cylinder cone crusher is applied to a plurality of industries such as mining industry, metallurgy, building, chemical industry, electric power, traffic and the like. The crusher has the characteristics of convenient adjustment of a discharge port, automatic passing of non-crushed objects, hydraulic clearing of the non-crushed objects blocked in the crushing cavity and the like, and has comprehensive performance superior to that of the traditional crusher. When the multi-cylinder cone crusher is used, core moving parts such as an internal eccentric copper bush and the like are lubricated and cooled by lubricating oil, and parts such as a moving cone assembly, an eccentric assembly, a rack assembly and the like move relatively. Between each two, the lubricating oil needs to be sealed to prevent dust from entering the oil passage to cause pollution of the lubricating oil. A common sealing structure is a non-contact labyrinth seal, and a labyrinth gap changes. One side of the gap becomes larger, and the other side becomes smaller. On one side of the inner core component, dust easily enters the inner oil duct to pollute lubricating oil, the sealing effect is poor, and the inner core component is easily worn and torn after the lubricating oil becomes dirty.
Disclosure of Invention
An object of the utility model is to provide a cone crusher seal structure that prevents dust through the sealed flexible contact seal structure that constitutes with special-shaped seal of I shape, and is sealed effectual, and the installation is changed simple and conveniently.
The utility model adopts the technical proposal that: the utility model provides a cone crusher seal structure that prevents dust, comprises I shape sealing washer and dysmorphism sealing washer, the transversal U-shaped structure of personally submitting of dysmorphism sealing washer, the outside side structure that distributes of U-shaped structure, dysmorphism sealing washer overlaps on I shape sealing washer.
Preferably, the core part of the special-shaped sealing ring is a soft framework, and the surface layer is a rubber layer.
Preferably, the core part of the special-shaped sealing ring is made of soft metal to form a soft framework, the surface layer is made of soft rubber to form a rubber layer, the tail part of the side structure is made of full soft rubber, and the tail part of the side structure is in contact with a part to be sealed to form contact sealing.
Further preferably, an I-shaped sealing ring is installed in a groove of the movable cone assembly 1 through special glue, a special-shaped sealing ring is sleeved on the I-shaped sealing ring and is attached through pressing, and the side edge of the special-shaped sealing ring is in contact with the side face of a sealing groove of the eccentric assembly to form a contact sealing structure of the movable cone assembly and the eccentric assembly.
Further preferably, the two I-shaped sealing rings are respectively installed in the two grooves of the rack assembly through special glue, and the special-shaped sealing rings are sleeved on the I-shaped sealing rings and are attached to each other through pressing. The side edge of the special-shaped sealing ring is contacted with the side surface of the sealing groove of the eccentric assembly to form a contact sealing structure at the position of the eccentric assembly and the rack assembly.
I shape sealing washer and special-shaped sealing washer are a contact seal structure, even move the slight irregular swing that cone assembly and eccentric assembly abnormal vibration lead to, also inside the effectual dust that has prevented that can last got into the breaker, the effectual lubricating oil that prevents is polluted. The sealing structure has the characteristics of simple manufacture, convenient installation, reliable sealing, oil resistance, wear resistance, certain flexibility and the like.
The utility model has the advantages that: the flexible contact type sealing structure is formed by the I-shaped sealing ring and the special-shaped sealing ring, the sealing effect is good, the installation and the replacement are simple and convenient, and the flexible contact type sealing structure is particularly suitable for dustproof sealing of a movable cone assembly and an eccentric assembly of a multi-cylinder cone crusher and dustproof sealing of the eccentric assembly and a rack assembly.
Description of the drawings:
FIG. 1 is an assembly schematic of a multi-cylinder cone crusher.
FIG. 2 is a partial schematic view of the dust seal at the moving cone assembly and the eccentric assembly.
FIG. 3 is a partial schematic view of the eccentric assembly and the frame assembly for dust sealing.
Fig. 4 is a schematic view of a profiled sealing structure.
The specific implementation mode is as follows:
the present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1-2, the sealing structure at the moving cone assembly 1 and the eccentric assembly 2 of the multi-cylinder cone crusher: the I-shaped sealing ring 4 is installed in a groove of the movable cone assembly 1 through special glue, the special-shaped sealing ring 5 is sleeved on the I-shaped sealing ring 4 and is attached through pressing, and the side edge of the special-shaped sealing ring 5 is in contact with the side face of the sealing groove of the eccentric assembly 2 to form a contact sealing structure.
As shown in fig. 3, the sealing structure between the eccentric assembly 2 and the frame assembly 3: two I-shaped sealing rings 4 are respectively installed in two grooves of the rack assembly 3 through special glue, and a special-shaped sealing ring 5 is sleeved on the I-shaped sealing ring 4 and is attached through pressing. The side edge of the special-shaped sealing ring 5 is contacted with the side surface of the sealing groove of the eccentric assembly 2 to form a contact sealing structure.
Through the combined sealing structure of the I-shaped sealing ring 4 and the special-shaped sealing ring 5, the sealing structure is arranged at the joint of two relative motion parts, dust is continuously and effectively prevented from entering the internal oil ducts of the movable cone assembly 1, the eccentric assembly 2 and the rack assembly 3, the pollution of lubricating oil in the oil ducts is avoided, and the service lives of the lubricating oil and vulnerable parts are prolonged.
The I-shaped seal ring 4 is a seal ring having an I-shaped cross section. The cross section of the special-shaped sealing ring 5 is in a U-shaped structure as shown in figure 4, and side structures are distributed outside the U-shaped structure.
