Abstract

The utility model discloses a flanged conical tray on a gasification furnace. The flanged conical tray structurally comprises a conical barrel body, wherein the upper end of the conical barrel body is provided with a large conical tray opening with a flange, the lower end of the conical barrel body is provided with a small conical tray opening, a base plate is arranged outside the conical barrel body at the flange of the large conical tray opening, a rigid ring is arranged outside the conical barrel at the small conical tray opening, the height of the rigid ring is larger than the wall thickness of the conical barrel body, and the ring width of the rigid ring is three times larger than the wall thickness of the conical barrel body and is not less than 50mm. The flanged conical tray disclosed by the utility model has the beneficial effects that as the rigid ring is arranged outside the conical barrel body at the small conical tray opening and a gap between the small conical tray opening and the rigid ring is evenly adjusted, the roundness requirement of the small conical tray opening is ensured, raw materials are saved, the machining cost is reduced and the production efficiency is also improved.

Description

Flanging cone dish on the vapourizing furnace

Technical field

The utility model relates to the vapourizing furnace field, refers more particularly to the flanging cone dish on the vapourizing furnace.

Background technology

Vapourizing furnace inside is provided with flanging cone dish, be mainly used in fixedly mounting the cinder notch coil pipe, its structure comprises: conical shell, the upper end of conical shell is the large mouth of cone dish with flanging, the lower end of conical shell is cone dish osculum, conical shell at large mouthful of flanging place of cone dish is outside equipped with backing plate, and the conical shell of a large mouthful of end of cone dish is connected with the vapourizing furnace cylindrical shell.Because the assembly precision of flanging cone dish is had relatively high expectations, usually require large and small mouthful of concentricity within 2mm, therefore require also higher to the circularity of large mouthful of cone dish and cone dish osculum.The circularity of the large mouth of cone dish is by the backing plate on large mouthful of place of the cone dish conical shell is machined to reach at present, the mode that the circularity of cone dish osculum then takes made allowance to be configured realizes, and configuration cone dish osculum need expend a large amount of man-hours and material, and tooling cost height and production efficiency are low.

The utility model content

The utility model technical issues that need to address are: provide a kind of simple in structure, can guarantee the circularity of cone dish osculum, and can save starting material, the flanging cone dish on the vapourizing furnace that cuts down finished cost, enhance productivity.

For addressing the above problem, the technical solution adopted in the utility model is: the flanging cone dish on the vapourizing furnace, its structure comprises: conical shell, the upper end of conical shell is the large mouth of cone dish with flanging, the lower end of conical shell is cone dish osculum, conical shell at large mouthful of flanging place of cone dish is outside equipped with backing plate, conical shell at cone Pan Xiaokouchu is outside equipped with stiffening ring, the height of described stiffening ring is greater than the wall thickness of conical shell, and the ring width of described stiffening ring is greater than the wall thickness of three times of conical shells and be not less than 50mm.

The beneficial effects of the utility model: outside the conical shell of cone Pan Xiaokouchu, stiffening ring is set, the gap adjustment of then cone being coiled between osculum and the stiffening ring is even, so just guaranteed the circularity requirement of cone dish osculum, and starting material have not only been saved, reduce tooling cost, also improved production efficiency.

Description of drawings

Fig. 1 is the structural representation of the flanging cone dish on the vapourizing furnace described in the utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and optimum embodiment.

As shown in Figure 1, flanging cone dish on the vapourizing furnace, its structure comprises: conical shell 1, the upper end of conical shell 1 is the large mouth 2 of cone dish with flanging, the lower end of conical shell 1 is cone dish osculum 3, conical shell 1 at large mouthful of 2 flanging places of cone dish is outside equipped with backing plate 4, conical shell 1 at cone dish osculum 3 places is outside equipped with stiffening ring 5, the height H of described stiffening ring 5 is greater than the wall thickness of conical shell 1, the ring width a of described stiffening ring 5 is greater than the wall thickness of three times of conical shells 1, and be not less than 50mm, the size of the height H of stiffening ring 5 and ring width a is not less than the rigidity of conical shell 1 as long as guarantee the rigidity of stiffening ring 5.

Add man-hour, the backing plate 4 outside the conical shell 1 at large mouthful of 2 flanging places of cone dish is carried out machining, thereby guaranteed the circularity of the large mouth 2 of cone dish; Stiffening ring 5 is sleeved on outside the conical shell 1 at cone dish osculum 3 places, then it is even cone to be coiled outer wall and the space adjustment between stiffening ring 5 inwalls of conical shell 1 at osculum 3 places with screw block, at last the conical shell 1 of stiffening ring 5 with cone dish osculum 3 places is welded and fixed.Use the flanging cone dish of said structure not only to fall and has saved starting material, low tooling cost has also improved production efficiency.

Claims

1. the flanging cone dish on the vapourizing furnace, its structure comprises: conical shell, the upper end of conical shell is the large mouth of cone dish with flanging, the lower end of conical shell is cone dish osculum, conical shell at large mouthful of flanging place of cone dish is outside equipped with backing plate, it is characterized in that: the conical shell at cone Pan Xiaokouchu is outside equipped with stiffening ring, and the height of described stiffening ring is greater than the wall thickness of conical shell, and the ring width of described stiffening ring is greater than the wall thickness of three times of conical shells and be not less than 50mm.
