Specific implementation mode

To keep the technical solution of the utility model and advantage clearer, the utility model is implemented below in conjunction with attached drawing Mode is described in further detail.

The utility model embodiment provides a kind of sleeve-type chimney.Fig. 1 and Fig. 2 are referred to, wherein Fig. 1 is that this practicality is new The schematic diagram of the sleeve-type chimney of type embodiment, Fig. 2 are the partial enlarged view at A in Fig. 1.As depicted in figs. 1 and 2, this reality The sleeve-type chimney for applying mode includes：Outer barrel 1 is set to the basis 2 inside the outer barrel 1, is set on described basic 2 extremely A few inner cylinder 3, the first support plate 4 being set on described basic 2, the lower face of first support plate 4 and the inner cylinder 3 It is fixedly connected, and first support plate 4 has multiple first through hole 401, is set on the lateral wall of the inner cylinder 3 , the second support plate 5 with multiple second through-holes 501, the first through hole 401 is corresponded with second through-hole 501, Across the first through hole 401 and second through-hole 501, and the anchor bolt 6 being embedded in described basic 2.

The operation principle of the sleeve-type chimney of the utility model embodiment is：

As depicted in figs. 1 and 2, it is fixedly connected with the first support plate 4 due to the lower face of inner cylinder 3, on the lateral wall of inner cylinder 3 It is provided with the second support plate 5, and first through hole 401 and the second through-hole 501 correspond, anchor bolt 6 passes through 401 He of first through hole Second through-hole 501 is simultaneously embedded in basis 2 so that the lower face of inner cylinder 3 is fixed with basis 2 with lateral wall so that this implementation The inner cylinder 3 of the sleeve-type chimney of mode is fixed more secured with basis 2.

The outer barrel 1 of the sleeve-type chimney of present embodiment can be built by armored concrete；Basis 2 can also be by steel Reinforced concrete is built；Inner cylinder 3 can be two, be made by erosion-resisting steel；First support plate 4 and second supports Plate 5 can be that the stainless steel plate that intensity height is not susceptible to be bent is made.In turn, the first support plate 4 can be welded with inner cylinder 3 It connects, the second support plate 5 can be welded with inner cylinder 3.

The meaning for " first through hole 4 is corresponded with the second through-hole 5 " that the utility model refers to is to refer to Fig. 3, Fig. 3 For the vertical view of Fig. 2.Since anchor bolt 6 passes through first through hole 401 and the second through-hole 501, in figure 3, anchor bolt 6 is by first through hole 401 block with the second through-hole 501.However even if first through hole 401 and the second through-hole 501 are not shown in Fig. 3 from Fig. 3 It can be seen that " first through hole 4 is corresponded with the second through-hole 5 " is that first through hole 401 is equal with the quantity of the second through-hole 501, and And the axis of the two overlaps.Can be by a kind of specific implementation that anchor bolt 6 is embedded in basis 2, by the way that high intensity is perfused Grouting material by anchor bolt 6 be embedded in basis 2 in, to by inner cylinder 3 be fixed on basis 2 on.

In the present embodiment, as shown in Figure 1, there is the outer barrel 1 first floss hole 101, the inner cylinder 3 to have second Floss hole 301, first floss hole 101 form flue X with second floss hole 301.Flue gas from the first floss hole 101 into Enter in the sleeve-type chimney of present embodiment, enters inner cylinder 3 from the second floss hole 301 by flue X, then from present embodiment Sleeve-type chimney discharge.

In the present embodiment, the first support plate 4 is arranged in parallel with the second support plate 5, and first through hole is passed through convenient for anchor bolt 6 401 and second through-hole 501, inner cylinder 3 is fixed on basis 2.

In the present embodiment, as shown in figure 3, the first support plate 4 is annular backup pad, multiple first through hole 401 are along ring The even circumferential of shape support plate is distributed, and the first support plate 4 is an entirety, big with the lower face contact area of inner cylinder 3, accordingly Ground, the pressure by inner cylinder 3 is small, enhances the supporting role to inner cylinder 3.

In addition, in the present embodiment, as shown in figure 3, the second support plate 5 is multiple, each second support plate 5 has one A second through-hole 501.It may occur to persons skilled in the art that radially uniform point along inner cylinder 3 of multiple second support plates 5 The distance of cloth, i.e., multiple second support plates 5 to basis 2 is equal.Not only the materials of the second support plate 5 can have been saved, but also have been convenient for second Support plate 5 is arranged on the lateral wall of inner cylinder 3.

In order to reinforce supporting role of second support plate 5 to inner cylinder 3 in the axial direction, sleeve-type chimney further includes：Connection The strengthening part of first support plate 4 and the second support plate 5, strengthening part can be metal cartridge, such as stainless steel cylinder, or for such as Metallic plate 7 shown in Fig. 3.Metallic plate 7 is preferably stainless steel plate, the both ends of metallic plate 7 respectively with the first support plate 4 and second Fagging 5 welds.First support plate 4, the second support plate 5 and metallic plate 7 form 3 D stereo support to inner cylinder 3 so that inner cylinder 3 are more securely disposed on basis 2.Metallic plate 7 can be one piece of stainless steel plate, substantially it is parallel with the circumference of inner cylinder 3 (such as Shown in Fig. 2), or two pieces of stainless steel plates, it is substantially vertical (as shown in Figure 3) along the circumference of inner cylinder 3.

When in order to slow down inner cylinder 3 by external force, to the active force of anchor bolt 6 and basis 2, as shown in Fig. 2, present embodiment Sleeve-type chimney further includes：Cushion pad 8 in the second support plate 5 is set, and cushion pad 8 is made of the material of soft texture.It is slow Cushioning effect can be played by the first support plate 5 and the second support plate 5 to the active force of anchor bolt 6 and basis 2 by rushing pad 8, effectively anti- The anchor bolt 6 being only embedded in basis 2 loosens.Cushion pad 8 can be rubber pad.The thickness of cushion pad 8 can be 40- 60mm, preferably 50mm.It is understood that with cushion structure, it is possible to reduce the height on basis 2, The size and number of anchor bolt can be reduced, also inner cylinder 3 can be firmly arranged on basis 2, telescopic cigarette is built to save The cost of chimney.

In the present embodiment, as shown in Figure 1, the sleeve-type chimney further includes：For connect the inner cylinder 3 with it is described The component 9 of outer barrel 1, to prevent the inner cylinder 3 from shaking.

It the above is only for the ease of it will be understood by those skilled in the art that the technical solution of the utility model, not limiting The utility model.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, should all It is included within the scope of protection of this utility model.
