Abstract

According to the material receiving ash bucket of the electric dust removal equipment, the triangular beam is composed of the bottom plate, the vertical plate, the inclined side plate and the triangular stable structure, and the rigidity of the triangular beam is superior to that of a rectangular beam. When the ash bucket is connected with the shell, the ash bucket plate is attached to the inclined plate of the triangular beam, the upper end of the ash bucket plate is welded with the inclined plate, and the back of the ash bucket plate is welded with the bottom plate of the triangular beam, so that the ash bucket plate and the shell are connected through two welding lines. When the ash bucket is filled with ash, all the weights have a component force in the lateral direction to press on the triangular beam, the tensile stress of the welding line is reduced, and the welding line cannot be damaged after long-term operation.

Description

Dust collecting hopper of electric dust removing equipment

Technical Field

The invention relates to electric precipitation equipment, in particular to a material receiving ash hopper of the electric precipitation equipment.

Background

The electric dust collector body is provided with a shell and an ash bucket in the middle except an inlet and an outlet horn box, and the shell and the ash bucket are welded into a whole. An anode and a cathode system are arranged in the rectangular box type shell. The removed dust falls into a dust hopper and is discharged through a sealed dust discharge valve. The ash bucket is in an inverted square cone shape, the upper opening is larger, the lower opening is smaller, and the upper opening is connected with the shell. The shell is divided into a plurality of electric fields, the ring beams at the lower part are also divided into a plurality of blocks which are connected with the ash buckets, and one ash bucket is arranged in each electric field along the airflow direction. If the dust hopper and the shell are only connected and welded at the end parts, the welding seam bears the weight of the dust hopper and the dust stored in the dust hopper, and the large-scale electric dust remover requires the dust hopper to store 8 hours of dust. If the hopper is full of ash, the weight of the hopper plus the ash will exceed 100t, and the weld will be pulled apart. Even if the rectangular connecting support beam is added between the ring beams, the end faces of the steel plates are still connected and welded, and the welding seam bears the tensile force and is easy to crack.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention aims to provide the stably-connected ash bucket for the electric dust removal equipment.

In order to achieve the above purposes, the invention has the following beneficial effects:

the electrostatic precipitator connects the material ash bucket, the ash bucket is the square cone form, and the suitable for reading of ash bucket welds in the bottom of casing, the suitable for reading of ash bucket is connected through triangular beam or half triangular beam between casing and casing.

Further, the triangular beam comprises two inclined side plates, a vertical plate and a bottom plate, wherein the vertical plate is vertically welded on the upper surface of the bottom plate, two ends of each inclined side plate are respectively welded on the vertical plate and the bottom plate and are arranged in an isosceles triangle shape with the bottom plate, the upper surface of the vertical beam is welded with the bottom of the shell, and the outer surfaces of the two inclined side plates are welded with the outer surface of the ash bucket.

Still further, half triangle roof beam includes oblique curb plate, riser and bottom plate, the riser welds in the upper surface of bottom plate perpendicularly, the both ends of oblique curb plate weld respectively in riser and bottom plate to be isosceles triangle shape with bottom plate and riser and set up, perpendicular roof beam upper surface and the interior right angle edge welding of casing bottom, the surface of oblique curb plate and the surface welding of ash bucket.

After the technical scheme is adopted, the invention has the beneficial effects that:

the triangular beam is composed of a bottom plate, a vertical plate, an inclined side plate and a triangular stable structure, and the rigidity of the triangular beam is superior to that of a rectangular beam. When the ash bucket is connected with the shell, the ash bucket plate is attached to the inclined plate of the triangular beam, the upper end of the ash bucket plate is welded with the inclined plate, and the back of the ash bucket plate is welded with the bottom plate of the triangular beam, so that the ash bucket plate and the shell are connected through two welding lines. When the ash bucket is filled with ash, all the weights have a component force in the lateral direction to press on the triangular beam, the tensile stress of the welding line is reduced, and the welding line cannot be damaged after long-term operation.
