Description

Combined feeding sealing structure
Technical Field
The utility model relates to a modular feeding seal structure belongs to mineral grinding equipment.
Background
The slurry leakage at the feed inlet of the wet ball mill is a common problem at present, and the slurry leakage not only pollutes the environment and hinders the maintenance, but also possibly leaks the slurry to the main bearing part to generate great influence on the service life of the bearing bush, so that the mill cannot normally run. And the existing sealing modes are worn due to simple structure and long-term operation, so that the problem of slurry leakage at the mouth of the feeding pipe is difficult to effectively solve.
Disclosure of Invention
The utility model aims to solve the technical problem that to the defect that prior art exists, a modular sealed design of feeding is provided for solve the feed portion and leak the thick liquid problem.
In order to solve the technical problem, the utility model provides a combined feeding sealing structure, which comprises a sealing flange, lip seals, a spacing ring and a gland, wherein the sealing flange is fixed on a feeding bushing by using screws, the two lip seals are arranged in the sealing flange, the spacing ring is arranged between the two lip seals, and a sealing oil cavity is formed between the lip seals and the spacing ring; the inner circle of the gland is provided with a labyrinth seal structure with the interval and the inner diameter of R2, and the labyrinth seal structure is fixed on the seal flange through screws.
The sealing flange material chooses HT200 to make for use, and the sealing flange is radial to be equipped with 4 screw holes for lubricating and sealed that are 90.
The material of the spacing ring is 25# steel, and a plurality of radial through holes are formed in the circumference of the spacing ring.
The lip seal is made of polyurethane.
The gland is made of HT 200.
The grease enters the sealing flange through a cone joint and a rubber pipe which are connected to the sealing flange, and then enters the sealing oil cavity through a hole in a spacing ring matched with the sealing flange.
Has the advantages that: the utility model discloses the butter that will get into sealing flange enters into sealed oil intracavity through the hole on the spacer ring, both can form sealed effect because of oil pocket pressure and can lubricate sealing device, cool down again to the problem is revealed to the thick liquid of effectively solving the feeding portion.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Fig. 2 is a schematic structural diagram of the present invention.
The utility model provides a modular feeding seal structure, including sealing flange 2, lip seal 3, spacer ring 4 and gland 5.
The sealing flange 2 is fixed on the feeding bushing 1 by using screws, the two lip seals 3 are arranged in the sealing flange 2, a spacing ring 4 is arranged between the two lip seals 3, and a sealing oil cavity is formed between the lip seals 3 and the spacing ring 4; the inner circle of the gland 5 is provided with a labyrinth seal structure with the interval of 7 and the inner diameter of R2, and the labyrinth seal structure is fixed on the seal flange 2 through screws.
Fig. 3 is a schematic structural view of the sealing flange of the present invention.
The material of the sealing flange 2 is HT200, the sealing flange 2 is radially provided with a threaded hole of 4-M10 multiplied by 1 at 90 degrees, and the later-stage grease delivery is convenient for lubrication and sealing.
Fig. 4 is a schematic structural view of the spacer ring of the present invention.
The material of the spacing ring 4 is 25# steel, and 8-phi 10 radial through holes are formed in the periphery of the spacing ring 4 and matched with the sealing flange 2 to enable grease to smoothly enter the oil cavity.
The material that lip seal 3 chose for use is polyurethane, forms sealed oil pocket between lip seal 3 and the spacer ring 4, and the butter that gets into through sealing flange 2 and spacer ring 4 has pressure in sealed oil pocket to reach multiple functions such as sealing, lubrication, cooling.
Fig. 5 is a schematic structural view of the gland of the present invention.
The gland 5 is made of HT200, and a labyrinth sealing structure of an inner circle of the gland is matched with the feeding chute to have a sealing effect.
The butter enters the sealing flange 2 through a conical joint and a rubber pipe which are connected to the sealing flange 2, and then enters the sealing oil cavity through a hole on the spacing ring 4 matched with the sealing flange 2.
The utility model discloses during the installation, at first feeding elephant trunk 6 and feeding bush 1 are according to the design position installation cooperation, secondly use the screw to fix sealing flange 2 on feeding bush 1, then put spacer ring 4 and install between two lip seals 3 inside sealing flange 2, pass through the fix with screw gland 5 on sealing flange 2 at last.
The utility model discloses the butter that will get into sealing flange enters into sealed oil intracavity through the hole on the spacer ring, both can form sealed effect because of oil pocket pressure and can lubricate sealing device, cool down again to the problem is revealed to the thick liquid of effectively solving the feeding portion.
The above embodiments of the present invention are merely examples, not the only ones, and all changes within the scope of the present invention or the same range of the present invention are all surrounded by the present invention.
