Description

Anti-blocking structure of nonmetal expansion joint of horizontal flue

Technical Field

The utility model relates to a horizontal rubbish boiler technical field specifically is a horizontal flue non-metal expansion joint prevents stifled structure.

Background

Considering the factors of the stability and the operation reliability of the boiler, an expansion joint needs to be arranged in the horizontal flue of the boiler to deal with the relative displacement of the structural member caused by thermal expansion. Because the horizontal flue of the garbage incinerator has more heated surfaces, the amount of ash adhered to the heated surfaces is generally large, and after the ash blowing device blows ash, a large amount of ash is deposited, most of the ash flows into the conveyor through the ash bucket, and the rest of the ash is deposited at the bottom of the expansion joint of the horizontal flue. Because the structural style of the bottom of the expansion joint of the horizontal flue of the garbage incinerator is not reasonable, the interior of the expansion joint often deposits ash, as shown in figures 1 and 2, an ash deposition area is formed, the formation of the ash deposition area reduces the expansion space of the expansion joint, and then the expansion joint is blocked, so that the expansion of a boiler is influenced.

Disclosure of Invention

In order to solve the inside easy deposition of current non-metallic expansion joint and lead to the dead problem of expansion joint card, the utility model provides a non-metallic expansion joint of horizontal flue prevents stifled structure, and it can prevent effectively that the ash from getting into the expansion joint, guarantees the normal use of expansion joint.

The technical scheme is as follows: the utility model provides a nonmetal expansion joint of horizontal flue prevents stifled structure, its includes horizontal flue, the last expansion joint that installs of horizontal flue, the expansion joint includes left frame, right frame, covering and heat preservation cotton, left side frame with right side frame is formed by two vertical folded plates and two horizontal folded plates welding, left side frame with all the welding has two vertical steel sheets and two horizontal steel sheets on the frame of the right side, left side frame with the lower part of right side frame is two leave the clearance between the horizontal steel sheet, a serial communication port, the lower part of left side frame horizontal steel sheet tip is equipped with the folded plate, the folded plate is located the lower part of right side frame the horizontal steel sheet top, folded plate tip sliding support in on the channel-section steel of right side frame.

The folding plate is further characterized in that the folding plate and the horizontal steel plate at the lower part of the left frame are integrally formed and are in an inverted Z shape;

one side of the folded plate is abutted to the vertical steel plate of the right frame but is not welded, and a gap of 1-2mm is reserved between the other side of the folded plate and the vertical steel plate of the right frame.

Adopt the utility model discloses afterwards, increased the folded plate, changed original bottom structure, will leak grey department originally and block, eliminated the deposition district, the disappearance in deposition district leaves enough space for the relative displacement that the boiler thermal expansion produced, has ensured the normal safe operation of boiler.

Detailed Description

Referring to fig. 3, 4 and 5, the anti-blocking structure of the nonmetal expansion joint of the horizontal flue comprises the horizontal flue, the expansion joint is arranged on the horizontal flue, the expansion joint comprises a left frame 1, a right frame 2, a skin 3 and heat insulation cotton 4, the left frame 1 and the right frame 2 are respectively formed by welding two vertical folding plates 5 and two horizontal folding plates 6, two vertical steel plates 7 and two horizontal steel plates 8 are respectively welded on the left frame 1 and the right frame 2, a gap is reserved between the two horizontal steel plates 8 at the lower parts of the left frame 1 and the right frame 2, because the smoke flows from left to right, the horizontal steel plate 8 at the lower part of the left frame 1 is higher than that of the right frame 2, the end part of the horizontal steel plate 8 at the lower part of the left frame 1 is provided with a folding plate 9, the folding plate 9 is positioned above the horizontal steel plate 8 at the lower part of the right frame 2, the end part of the folding plate 9 is slidably supported on a channel steel 10 of the right frame 2 without welding, for sliding in the expansion direction, a flap 9 is integrally formed with the horizontal steel plate 8 of the lower part of the left frame 1 in an inverted Z-shape, usually for the sake of simplicity of construction and improved stability. The flap 9 shields the gap in the original expansion joint from the ingress of ash.

One side of the folded plate 9 is abutted to the vertical steel plate 7 of the right frame 2 but not welded, and a gap of 1-2mm is reserved between the other side of the folded plate and the vertical steel plate 7 of the right frame 2, the abutting is used for preventing ash leakage, and an expansion space is reserved when the gap is reserved.
