Abstract
A kind of new type sealing device for cement grinding mill high-efficient powder concentrator, it includes convex type ring (1), concave ring (2) and L-shaped sealing ring (11), convex type ring (1) is fixedly mounted on the spreading disk in powder concentrator (3), concave ring (2) is fixedly mounted on powder concentrator (4), concave ring (2) includes the sides A (5), the sides B (6) and bottom edge (7), one end of the sides A (5) is inclined-plane, and convex type ring (1) includes pedestal (8) and bulge loop (9)；Advantage is：High-efficient powder concentrator is solved because run time is long, labyrinth seal is worn, and the product fineness occurred runs thick phenomenon, and ensure that cement selects silty amount.
Description
Technical field
The utility model is related to powder concentrator apparatus fields, and in particular to a kind of for the novel close of cement grinding mill high-efficient powder concentrator
Seal apparatus.
Background technology
Currently, O-Sepa high-efficient powder concentrators are applied on more and more cement producing lines, high-efficient powder concentrator sealing adopts
With the form of labyrinth seal ring, i.e. concave groove and convex type ring is combined, and after powder concentrator runs a period of time, sealing ring will appear
The case where abrasion.
It will appear product fineness after abrasion to run thick or coarse grained technique hidden danger occur, so that product quality is declined, also result in
Yield declines, and cement cost rises, and seriously affects being normally carried out for manufacture of cement.
Utility model content
The purpose of this utility model provides a kind of for the new of cement grinding mill high-efficient powder concentrator aiming at above-mentioned deficiency
Type sealing device.
It includes convex type ring, concave ring and L-shaped sealing ring to the utility model,
Convex type ring is fixedly mounted on the spreading disk in powder concentrator, and concave ring is fixedly mounted on powder concentrator,
Concave ring includes the sides A, the sides B and bottom edge, and one end of the sides A is inclined-plane, and convex type ring includes pedestal and bulge loop,
The side corner of bulge loop be inclined-plane, bulge loop between the sides A and the sides B,
The endpoint on the sides A inclined-plane and the minimum spacing that bulge loop side corner is inclined-plane are H, H 3-4mm,
The sides B are equipped with annular groove, and the side of L-shaped sealing ring is plugged in annular groove,
Pressure-air import is provided on concave ring, pressure-air import between bulge loop and the sides A,
Annular is uniformly provided with one group of pressure-air import on concave ring, and one group of pressure-air import is respectively positioned on bulge loop and the sides A
Between side.
L-shaped sealing ring is rich chromium cast iron sealing ring.
The utility model advantage is：High-efficient powder concentrator is solved because run time is long, labyrinth seal is worn, and occur
Product fineness runs thick phenomenon, and ensure that cement selects silty amount.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Specific implementation mode
As shown in the picture, the utility model it include convex type ring 1, concave ring 2 and L-shaped sealing ring 11,
Convex type ring 1 is fixedly mounted on the spreading disk 3 in powder concentrator, and concave ring 2 is fixedly mounted on powder concentrator 4,
Concave ring 2 includes the sides A 5, the sides B 6 and bottom edge 7, and one end of the sides A 5 is inclined-plane, and convex type ring 1 includes pedestal 8
With bulge loop 9,
The side corner of bulge loop 9 be inclined-plane, bulge loop 9 between the sides A 5 and the sides B 6,
The endpoint on 5 inclined-plane of the sides A and the minimum spacing that 9 side corner of bulge loop is inclined-plane are H, H 3-4mm,
The sides B 6 are equipped with annular groove 10, and the side of L-shaped sealing ring 11 is plugged in annular groove 10,
Pressure-air import 12 is provided on concave ring 2, pressure-air import 12 between bulge loop 9 and the sides A 5,
Annular is uniformly provided with one group of pressure-air import 12 on concave ring 2, and one group of pressure-air import 12 is respectively positioned on bulge loop 9
Between the sides A 5.
L-shaped sealing ring 8 is rich chromium cast iron sealing ring.Rich chromium cast iron sealing ring has better wearability.
Working method：Wait for that sorting material is fallen into powder concentrator on spreading disk 3 by feeding mouth 13, for a long time due to powder concentrator
Operation, labyrinth seal concave groove and convex type ring are gradually worn out, and product fineness are occurred and are run thick phenomenon,
The chamfering of the 9 side corner of inclined-plane and bulge loop of 5 one end of the sides A constitutes the sky with exclusion material function outward
Gap prevents large particle from squeezing into labyrinth seal face, causes sealing surface wear；Annular is uniformly provided with and one group on powder concentrator 4
12 corresponding high-pressure air inlet of pressure-air import, the high-pressure air inlet on powder concentrator 4 are passed through pressure-air,
Pressure-air flows downward along the gap formed between the sides A 5 and bulge loop 9,
It is finally discharged by the gap that the chamfering of 9 side corner of the inclined-plane of 5 one end of the sides A and bulge loop forms, further
Prevent material from entering in labyrinth seal face；L-shaped sealing ring 11 makes the material leaked out along labyrinth seal face turn back to move downward, due to
The coarse grained larger certainty of inertia is detached with fine powder.
