Description

Disc type boiler partition pipe tooth-shaped device

Technical Field

The utility model relates to a boiler equipment field, concretely relates to disc type boiler separates pipe tooth device.

Background

The boiler tube is a steel material having both ends open and a hollow cross section, and the length thereof is larger than that of the periphery thereof, and is classified into a seamless steel tube and a welded steel tube according to the production method, and the specification of the steel tube is represented by the outer dimension (e.g., outer diameter or side length) and the wall thickness, and the size range thereof is wide, ranging from a capillary tube having a small diameter to a large-diameter tube having a diameter of several meters. The steel pipe can be used for pipelines, thermal equipment, machinery industry, petroleum geological exploration, containers, chemical industry and special purposes.

The body of the existing disc type oil and gas fired boiler is generally assembled in a horizontal mode. The partition pipe is placed on the inner side of the larger pipe ring, the partition pipe is welded on the coil pipe, the other pipe ring is pushed in, the partition pipe can generate large tensile force when the partition pipe is pushed in, the tensile force is transmitted to the welding position of the partition pipe and the coil pipe, the coil pipe is easy to crack by pulling, and the partition pipe is not easy to find when in assembly. If not welded, it is liable to fall off. Due to this structural limitation, when a hydraulic test is performed after the complete assembly, the site to be pulled apart is found to leak, which is difficult to repair.

Disclosure of Invention

The utility model aims at providing a disc type boiler separates pipe tooth form device, its utensil makes the pipe spacer put into the coil pipe circle, and adjacent coil pipe can normally assemble, separates the pipe not with the coil pipe welding again, solves the tensile reason and leads to the advantage of coil pipe seepage.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides a disc type boiler separates tub dentiform device, includes the furnace body, be equipped with the coil pipe in the furnace body, still be equipped with isolating device in the coil pipe, isolating device is including being located the tub that separates that is equipped with between the coil pipe, it is equipped with a plurality of tooth teeth of arranging side by side to separate between the pipe, the tooth top is smooth cylindrical, tooth and separate tub welded connection.

Further setting: the top end of the tooth is also provided with a buffer block.

Further setting: expansion devices are further arranged on two sides of the teeth, each expansion device comprises a ring sleeve arranged at the top end of each tooth and an expansion sleeve arranged on the ring sleeve and used for wrapping the teeth, and a through hole for the teeth to pass through is formed in the top end of each expansion sleeve.

Further setting: the top end of the tooth is provided with a groove matched with the ring sleeve.

Further setting: the tooth top is also provided with a plurality of lugs.

To sum up, the utility model discloses following beneficial effect has:

1. the risk of pulling and cracking the coil pipe caused by the transmission of the tensile force after welding is reduced, and the assembly is smoothly carried out.

2. Both horizontal and vertical disk-type boilers can be used.

3. Simple manufacture, convenient assembling.

Drawings

The present invention will be further explained with reference to the accompanying drawings.

FIG. 1 is a schematic structural diagram of a tooth-shaped device of a partition pipe of a disc-type boiler;

fig. 2 is an enlarged schematic view at a in fig. 1.

In the figure, 1, a furnace body; 2. a coil pipe; 3. an isolation device; 31. separating the tube; 32. teeth; 4. a buffer block; 5. an expansion device; 51. sleeving a ring; 52. an expansion sleeve; 53. a through hole; 6. a groove; 7. and (4) a bump.

Detailed Description

The following describes the embodiments of the present invention with reference to the accompanying drawings.

The utility model adopts the technical proposal that:

a disc-type boiler partition pipe tooth-shaped device is shown in figures 1 and 2 and comprises a furnace body 1, a coil pipe 2 is arranged in the furnace body 1, an isolating device 3 is further arranged in the coil pipe 2, the isolating device 3 comprises partition pipes 31 arranged between the coil pipe 2, a plurality of tooth teeth 32 arranged in parallel are arranged between the partition pipes 31, the top ends of the tooth teeth 32 are smooth and cylindrical, the tooth teeth 32 are connected with the partition pipes 31 in a welded mode, a buffer block 4 is further arranged at the top ends of the tooth teeth 32, expansion devices 5 are further arranged on two sides of the tooth teeth 32 and comprise ring sleeves 51 arranged at the top ends of the tooth teeth 32, expansion sleeves 52 wrapping the tooth teeth 32 are arranged on the ring sleeves 51, through holes 53 for the tooth teeth 32 to pass through are formed in the top ends of the expansion sleeves 52, grooves 6 matched with the ring sleeves 51 are formed in the top ends of the tooth teeth 32, and a plurality of convex blocks 7 are further arranged at the top ends of the tooth teeth 32.

The main working principle is as follows: the boiler body is of a round coil pipe 2 structure and is composed of a plurality of steel pipe rings, a flue gas channel is arranged between every two adjacent steel pipe rings, in order to ensure the space between the steel pipe rings, a separation pipe 31 is adopted for separation, the separation pipe 31 is not welded with the coil pipe 2 rings, teeth 32 are welded on the separation pipe 31 and are made of steel plates or round steel, the welding is firm, the surface is polished smooth and has no burrs, the space between the teeth 32 is the same as that between the steel pipe rings of the coil pipe 2, one tooth 32 can be welded at intervals of a plurality of steel pipes, the adjustment is carried out according to requirements during assembly, because the teeth 32 on the partition pipe 31 are clamped in the steel pipe gaps of the coil pipe 2 rings to fix the partition pipe 31, the other coil pipe 2 ring can be smoothly pushed in without tension transmission to damage the coil pipe 2 ring, for the vertical disc boiler, when the boiler is vertical, the partition pipe 31 can not fall out from the flue gas channel between the coil pipes 2 due to the structure, so the horizontal and vertical disc boilers can use the structure.

The above is the preferred embodiment of the present invention, and is not intended to limit the present invention in any form, and all the simple modifications, equivalent changes and modifications made by the technical entity of the present invention to the above embodiments all belong to the scope of the technical solution of the present invention.
