Embodiment 1

[0035] like Figure 1 to Figure 3 As shown, this embodiment designs a biomass gasifier, which includes an outer casing 1, a refractory brick 2, a cooling water pipe, and a furnace bridge 4 and other mechanisms.

[0036]The outer casing 1 includes four side wall plates with a surrounding rectangle, the upper and lower parts of each side wall plate are respectively provided with transverse plates 13, and the inner side of the transverse plates 13 is provided with a mouth vertical plate 15, and biomass gasification. The inlet of the furnace is a rectangular mouth surrounded by a plurality of mouth vertical plates 15 on the upper part of the side wall plate, and the outlet of the biomass gasifier is a rectangular mouth surrounded by a plurality of mouth vertical plates 15 on the lower part of the side wall plate. Refractory bricks 2 are respectively arranged on the inner side of each side wall plate, and the inner side of the refractory bricks 2 is the furnace cavity. The cooling...

Embodiment 2

[0044] In this embodiment, in order to standardize the production of shell slabs and facilitate the mass production of shell slabs, a method for producing shell slabs of biomass gasifiers is designed.

[0045] The production method includes the following steps:

[0046] Step S1 : cutting the metal plate according to the set size to obtain a rectangular main body vertical plate 11 , a trapezoidal transverse plate 13 and a rectangular mouth vertical plate 15 .

[0047] Step S2: Perform edge cutting and edge punching on the main body vertical plate 11, the horizontal plate 13 and the mouth vertical plate 15; in this step, the main body vertical plate 11, the horizontal plate 13 and the mouth vertical plate 15 are mainly processed. Dimension trimming, punching and bending at the same time.

[0048] Specifically, two long sides of the main body vertical plate 11 are respectively punched to form U-shaped holes 11d, and the U-shaped opening of the U-shaped hole 11d faces the short s...

Embodiment 3

[0054] like Figure 1 to Figure 4 As shown, on the basis of the second embodiment, in order to facilitate the relative fixation of the positions of the various components during the welding process in step S4, the present embodiment designs a welding tool frame 5 to be used together.

[0055] The welding tool frame 5 includes two upper and lower frame bodies, and the main body vertical plate 11, the transverse plate 13 and the mouth vertical plate 15 are clamped between the two frame bodies; the front and rear sides of the two frame bodies (refer to Figure 4 , the frame body in the figure is a top view, and the partially enlarged part in the figure is a side view) respectively connected with a hinge 53 and a lock 54; the bending strip is divided into an outer bending strip 14 and an inner bending strip 12; On the left and right sides of the frame body (reference Figure 4 ) are respectively provided with a transverse plate welding groove 56a, the welding connection between t...

Abstract

The invention belongs to the technical field of metal plate blank machining and forming, and particularly relates to a production method of a biomass gasifier shell plate blank, a shell of a biomass gasifier is formed by splicing two half shells, and each half shell is formed by bending the shell plate blank; the shell plate blank comprises a main body vertical plate, a transverse plate and an opening vertical plate, and the method comprises the following steps that a metal plate is cut according to the set size to obtain the rectangular main body vertical plate, the trapezoidal transverse plate and the rectangular opening vertical plate, and cutting and punching are conducted; stamping on the main body vertical plate to form two W-shaped edges, wherein the adjacent vertical plate parts can be bent along the W-shaped edges; and bending strips are respectively welded and connected between the transverse plate and the opening part vertical plate and between the transverse plate and the vertical plate part. The part, needing to be bent, of the outer shell structure is provided with a W-shaped edge or a bent strip easy to bend, so that the outer shell plate blank is in a flat plate shape, manual bending is conducted when the outer shell plate blank is used, and the transportation cost of the biomass gasification furnace is reduced.

Description

technical field [0001] The invention belongs to the technical field of metal slab processing and forming, and in particular relates to a method for producing shell slabs of biomass gasification furnaces. Background technique [0002] Biomass gasifier is a device that gasifies biomass through low oxygen and high temperature environmental conditions to produce combustible gas that can be used as energy for heating equipment. [0003] In the prior art, the patent No. CN215103057U discloses a high-temperature coking-proof biomass gasification furnace wall structure. The furnace walls around the furnace body are provided with upper and lower parts, which are the upper insulation wall located on the upper part of the furnace wall. , and the lower cooling stave located at the lower part of the furnace wall, the lower cooling stave is fixed on the furnace foot, and the upper thermal insulation wall is fixed on the lower cooling stave; the upper thermal insulation wall on the upper p...
