In a preferred embodiment of the present invention, the end of the cone structure with a small cross section of the inner tube is provided with an air outlet, and the end with a large cross section is provided with an air inlet.

In a preferred embodiment of the present invention, the air inlet extends into the outer tube accommodating cavity, and the air outlet extends out of the outer tube accommodating cavity.

In a preferred embodiment of the present invention, when the slider drives the inner tube to extend out of the outer tube accommodating cavity, the partition board pushes the side wall of the side air outlet to be folded, and the side air outlet is narrowed.

In a preferred embodiment of the present invention, one end of the outer tube is connected to a flange, and the flange is connected to an intake pipe.

In a preferred embodiment of the present invention, the slider is connected to the cylinder, and the slider is pushed to move by the cylinder.

The utility model provides a defect that exists among the background art, the utility model discloses possess following beneficial effect:

(1) the utility model provides a telescopic soot blower slip business turn over boiler improves the high temperature resistance ability of soot blower, and the easy access improves life, realizes exchanging that many gas ports and single gas port blown, and air-out speed obtains the speed adjustment.

(2) The utility model discloses when the inner tube gos deep into the boiler, the conversion gas outlet, by the single gas outlet of many gas outlets conversion, because the inner tube is the cone structure, the atmosphere mouth gets into little gas port, and the wind channel narrows, can improve the wind speed, strengthens blowing the ash speed.

(3) The utility model discloses the gas outlet on the inner tube is different with the gas position that the side gas outlet of outer tube blew off, can enlarge the position of blowing, improves and sweeps the area for blow grey speed, improve work efficiency.

(4) The utility model discloses well tuber pipe and inner tube have improved high temperature resistant flue gas for cup jointing the pipeline, and flexible business turn over boiler can improve life, and the easy access reduces the cost.

Drawings

The present invention will be further explained with reference to the drawings and examples;

FIG. 1 is a perspective view of a preferred embodiment of the present invention;

FIG. 2 is a perspective view of the preferred embodiment of the present invention;

fig. 3 is a schematic cross-sectional structure of a preferred embodiment of the present invention;

in the figure: an outer tube 1; an inner tube 2; a partition plate 3; a side gas outlet 4; a slider 5; a flange 6.

Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "upper", "lower", "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.

As shown in fig. 1 to 3, a retractable sootblower includes: outer tube 1, cup joint inner tube 2 in the outer tube 1 to and set up the baffle 3 at 2 casing outer walls in inner tube, outer tube 1 is cylindrical structure, inner tube 2 is the cone structure, the cross section diameter of inner tube 2 is less than 1 cross section diameter of outer tube, the interval cavity that 1 one end of outer tube and inner tube 2 formed sets up at least one side gas outlet 4, the lateral wall of side gas outlet 4 can be folded, baffle 3 can the inlay card in the lateral wall of side gas outlet 4, stretch into the one end link block 5 of inner tube 2 in the outer tube 1.

The one end that the 2 cross sections of inner tube of cone structure are little sets up the gas outlet, and the one end that the cross section is big sets up the air inlet, and the air inlet stretches into outer tube 1 and holds the intracavity, and the gas outlet stretches out outer tube 1 and holds the intracavity, and the one end flange 6 of outer tube 1, flange 6 connect the intake pipe because inner tube 2 is the cone structure, and big mouth gets into the little gas port, and the wind channel narrows down, can improve the wind speed, strengthens blowing the speed.

The sliding block 5 is connected with the cylinder, the sliding block 5 is pushed to move through the cylinder, when the sliding block 5 drives the inner pipe 2 to extend out of the accommodating cavity of the outer pipe 1, the partition plate 3 pushes the side wall of the side air outlet 4 to be folded, the side air outlet 4 is reduced, the soot blowing gun is lengthened, the air speed of the air outlet of the inner pipe 2 is increased, the soot blowing speed is high, the side air outlet 4 is gradually reduced, and the soot blowing area is intensively blown from large to small; when the inner tube 2 retracts into the outer tube 1 to accommodate the cavity, the side wall of the side air outlet 4 extends, the side air outlet 4 becomes large, large-area blowing is carried out, the air outlet is converted, the blowing position can be enlarged by converting a plurality of air outlets, the blowing area is increased, the blowing speed is increased, and the working efficiency is improved.

In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
