Description

Novel ash bucket filtering device of dust remover

Technical Field

The utility model relates to a dust removing and filtering device, in particular to a novel dust hopper filtering device of a dust remover.

Background

The ash bucket of the steelmaking dust remover is positioned below the dust remover body, and a star-shaped ash discharge valve is arranged below the ash bucket. When the dust remover works, dust in the dust remover pipeline enters the ash bucket from the lower part of the box body, and as the air flow cross-section area is suddenly enlarged, the flow speed is reduced, and a part of particles or sundries with relatively large diameter and large density in the air flow are settled in the ash bucket under the action of gravity. The dust in the ash bucket can be discharged through the ash conveying system by utilizing the periodical opening and closing of the star-shaped ash discharging valve below the ash bucket.

At present, a simple funnel-shaped structure is adopted for an ash bucket of the steelmaking dust remover, namely, an upper opening (inlet) is wide, a lower opening (outlet) is narrow, and the whole projection is trapezoidal. However, the ash bucket still has certain defects in the actual use process. Mainly because there is no filter screen in the ash bucket, when the broken grate bar, particles and sundries directly enter the star-shaped ash valve below the ash bucket, the star-shaped ash valve is easy to be blocked, and the service life of the star-shaped ash valve is shortened.

Detailed Description

The utility model is further described below in connection with the examples, which are not to be construed as limiting the utility model in any way, but rather as falling within the scope of the claims.

Referring to fig. 1-2, the novel ash bucket filtering device of the dust remover comprises a filter screen 4 and a plane screen 5. The filter screen 4 is used for filtering dust and small particle sundries in ash, and for broken grate bars, large particles or sundries, the dust and the small particle sundries cannot be filtered by the filter screen. The plane net 5 is used for collecting broken grate bars, large particles or sundries which cannot be filtered, so as to prevent the problem that the star-shaped ash discharge valve is blocked by a blocking device and facilitate quick ash removal.

Specifically, the filter screen 4 is fixed in the ash bucket 1, and the filter screen 4 is arranged obliquely. The inclination angle of the filter screen 4 is 45 °. In this embodiment, the filter screen 4 consists of a number of round steel pieces 41 arranged in parallel, the round steel pieces 41 being welded to the inner wall of the hopper 1. The axial direction of the round steel one 41 is consistent with the inclination direction of the filter screen 4. A filter gap 42 is arranged between two adjacent round steels 41. The width of the filter gap 42 is 20mm.

An access door 2 is installed at one side of the ash bucket 1, and a plane net 5 is positioned below the access door 2 so as to take out broken grate bars, large particles or sundries which cannot be filtered. One end of the filter screen 4 close to the bottom of the ash bucket 1 is fixedly connected with the plane screen 5. Wherein the plane net 5 is composed of a plurality of round steel II 51. The spacing between the two round bars 51 is 30mm so as to facilitate the falling of the powder layer following the broken grate bars, large particles or sundries which cannot be filtered. One end of the round steel II 51 is welded on the inner wall of the ash bucket 1, and the other end is welded with the round steel I41 through the connecting rod 6. The round steel one 41 and the round steel two 51 are steel bars with the diameter of 10 mm.

In order to prevent ash from directly falling onto the plane net 5, the ash bucket 1 above the plane net 5 in this embodiment is provided with a closing-in part 3 corresponding to the plane net 5, so that the closing-in part 3 has interference with the vertical projection position of the plane net 5, thereby avoiding the problem that ash directly falls onto the plane net 5 and facilitating the filtering of broken grate bars, large particles or sundries.

In order to prevent dust from scouring and corroding the inside of the ash bucket, an anti-rust paint layer is sprayed on the inner wall of the ash bucket 1 in the embodiment.

The working principle of the utility model is as follows: when the filtered matter falls onto the filter screen 4 in the hopper 1, the surface of the filter screen 4 is smoother because the filter screen 4 is integrally formed of round steel arranged obliquely, so that the filtered matter which cannot be filtered from the filter gap 42 is collected along the surface pulley of the filter screen 4 into the plane screen 5. The ash bucket 1 is used for regularly checking the accumulation condition of the plane net 5 and the blocking condition of objects on the filter screen 4, and when a certain amount of accumulation is collected on the plane net 5 or/and more objects are blocked on the filter screen 4, the access door 2 can be opened to take out the plane net 5 and the objects on the filter screen 4.

While only the preferred embodiments of the present utility model have been described above, it should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present utility model, and these do not affect the effect of the implementation of the present utility model and the utility of the patent.
