Description

Ash bucket flange

Technical Field

The utility model relates to the technical field of electric dust collectors, in particular to an ash bucket flange, which is a device for sealing an ash discharging opening of an electric dust collector more tightly.

Background

At present, the ash bucket flanges used by people are all formed by a group of two circular flanges, angle steel is adopted for bending and then welding, grinding and processing, one circular flange is welded with an ash bucket main body, the other circular flange is connected with ash unloading equipment at an ash bucket outlet, 18 holes are formed in double-flange connection, and M16 bolts and matched nut washers are penetrated for fixing. The contact surface between the two flanges is increased in friction force and sealing performance by using a rubber sealing gasket or an asbestos rope. Although the air tightness problem is considered, the air tightness and the dust leakage are not tight enough due to long-time use and abrasion, especially in places with relatively complex environment, and certain air leakage and dust leakage phenomena occur.

SUMMERY OF THE UTILITY MODEL

To above problem, the utility model provides an ash bucket flange, ash bucket flange have increased the V type groove similar to sealed waterline type at sealed face, have just so strengthened the leakproofness between ash bucket and the ash discharge equipment, have also prolonged the life of flange, reduce the equipment change number of times, have saved the expense of change equipment, have increased production time for the mill enterprise.

In order to achieve the above purpose, the utility model discloses the technical scheme who uses as follows:

the ash bucket flange comprises a circular flange, wherein a connecting bolt hole is formed in an angle steel ring on the outer edge of the circular flange, a first annular V-shaped groove is formed in the position, deviating from 25mm outwards, of the center of the connecting bolt hole, and a second annular V-shaped groove is formed in the position, deviating from 10mm outwards, of the V-shaped groove.

Preferably, the first V-shaped groove and the second V-shaped groove are arranged on the sealing surface of the angle steel ring at intervals.

Preferably, the width of the opening of the first V-shaped groove and the second V-shaped groove is 1mm, and the depth of the opening of the first V-shaped groove and the second V-shaped groove is 1 mm.

The utility model discloses beneficial effect:

the utility model discloses a such structure setting is equipped with V type groove one and V type groove two on the angle steel ring through edge outside the circular flange, has just so strengthened the leakproofness between ash bucket and the ash discharge equipment, has also prolonged the life of circular flange, reduces the equipment replacement number of times, has saved the expense of change equipment, has increased production time for the mill enterprise.

Detailed Description

The technical solution of the present invention will be described below with reference to the accompanying drawings and examples.

As shown in figures 1 to 4, an ash bucket flange, including the round flange, be equipped with connecting bolt hole 4 on the angle steel ring 1 on the outer edge of round flange, the outside skew 25mm department in connecting bolt hole 4's center is equipped with annular V type groove one 2, and the outside skew 10mm department in V type groove one 2 is equipped with annular V type groove two 3. Adopt such structure setting, through be equipped with V type groove one 2 and V type groove two 3 on the angle steel ring 1 on the outer edge of circular flange, just so strengthened the leakproofness between ash bucket and the ash discharging equipment, also prolonged the life of circular flange, reduced the equipment replacement number of times, saved the expense of changing equipment, increased production time for the mill enterprise.

In this embodiment, the V-shaped groove one 2 and the V-shaped groove two 3 are disposed on the sealing surface of the angle ring 1 at an interval. Adopt such structure setting, during the use, be in the same place two circular flanges through bolt assembly 6 are fixed in, and be equipped with rubber packing 5 between two circular flanges, the relative rubber packing 5 of V type groove one 2 and V type groove two (3), after screwing up bolt assembly 6, rubber packing 5 can be to V type groove one 2 and V type groove two 3 internal extrusion, has changed original plane seal's mode to reach the purpose of the strong leakproofness in environment.

In this embodiment, the width of the opening of the first V-shaped groove 2 and the second V-shaped groove 3 is 1mm, and the depth thereof is 1 mm.

In practical application, ash bucket flange choose for use angle steel 75X75X8, bending over this angle steel and guarantee that the flange inner circle is 400mm, locate to open 18 mm's circular connecting bolt hole 4 in 450mm border, totally 8, then the outside 25mm department of deviating in the center of connecting bolt hole 4 is equipped with V type groove one 2, the outside 10mm department of deviating in V type groove one 2 is equipped with V type groove two 3, fluting central diameter is 500mm and 520mm respectively, V type groove one 2 is 1mm with the opening width in V type groove two 3, the degree of depth is 1mm, press from both sides rubber packing pad 5 in the middle of two circular flanges, and it is fixed through M16 bolt, nut and packing ring.

The embodiments of the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, and these forms are within the scope of the present invention.
