Abstract

A hanging device of undamaged heating surface of a boiler of a serpentine tube relates to the hanging device of the heating surface of the serpentine tube. The hanging device resolves problems that the serpentine tube of the hanging device of the heating surface of the boiler is directly hinged to a tooth steel plate of a hanging tube, and the tooth steel plate is usually in contact with the serpentine tube of the heating surface rigidly in an assembly or transportation process so that the serpentine tube is damaged. The two serpentine tubes are arranged parallelly from top to bottom. The two rows of the heating surface serpentine tubes (2) are horizontally arranged, a plurality of hanging tubes (1) are vertically arranged between the two rows of the heating surface serpentine tubes (2). Two fixing holes (9) are arranged on each arc plate (8), each arc plate (8) is arranged on the serpentine tubes (2) adjacent to the hanging tubes (1), and a plurality of round steels (7) penetrate through the fixing hole (9) to fix the serpentine tubes (2) on the hanging tunes (1). The hanging device is suitable for the boiler.

Description

Coiled pipe does not have impaired boiler heating surface erecting by overhang

Technical field

The utility model relates to a kind of boiler heating surface erecting by overhang, and being specifically related to a kind of coiled pipe does not have impaired boiler heating surface erecting by overhang.

Background technology

Boiler heating surface typically refers to the metal surface area (opposite side contact with water or conduction oil) of contact flame or flue gas one side, and the heat exchange of boiler is carried out through such metal surface area, and boiler heating surface is big, and boiler capacity is just big, otherwise just little.Because the coiled pipe of existing boiler heating surface erecting by overhang directly is welded on the profile of tooth steel plate of hanging pipe, the profile of tooth steel plate often contacts with the coiled pipe of heating surface is rigid in assembling or transportation, causes the impaired problem of coiled pipe.

The utility model content

The purpose of the utility model is in order to solve because the coiled pipe of existing boiler heating surface erecting by overhang directly is welded on the profile of tooth steel plate of hanging pipe; The profile of tooth steel plate often contacts with the coiled pipe of heating surface is rigid in assembling or transportation; Cause the impaired problem of coiled pipe, and then provide a kind of coiled pipe not have impaired boiler heating surface erecting by overhang.

The technical scheme of the utility model is: coiled pipe does not have impaired boiler heating surface erecting by overhang and comprises that double heating surface coiled pipe and Duo Gen hang pipe; Every row's heating surface coiled pipe comprises two coiled pipes; Two coiled pipes from top to bottom are set up in parallel, and double heating surface coiled pipe laterally arranges, and hang pipe for many and are vertically set between the double heating surface coiled pipe; Coiled pipe does not have impaired boiler heating surface erecting by overhang and also comprises many round steel and a plurality of arc; All have two fixing holes on each arc, the equal spiral-lock of each arc with the coiled pipe of hanging Guan Xianglin on, many round steel pass fixing hole and coiled pipe is fixed on hangs on the pipe.

The utility model compared with prior art has following effect: 1. the utility model has removed the profile of tooth steel plate not influencing on the fixing integrally-built basis of suspention; Not only effectively reduced the workload of welding in the production process; Also reduced steel consumption, steel consumption be before steel consumption 1/5th, round steel and arc and pipe row's contact position slyness relatively simultaneously; Improve the impaired problem of heating surface, therefore can better guarantee the product integrality.2. simple in structure in process of production, cost is low, is easy to realize.

Description of drawings

Fig. 1 is the front view of the utility model; Fig. 2 is the partial enlarged drawing of Fig. 1 at the A place; Fig. 3 is that the B of Fig. 2 is to view.

The specific embodiment

The specific embodiment one: combine Fig. 1-Fig. 3 that this embodiment is described; The coiled pipe of this embodiment does not have impaired boiler heating surface erecting by overhang and comprises that double heating surface coiled pipe 2 and Duo Gen hang pipe 1; Every row's heating surface coiled pipe 2 comprises two coiled pipes; Two coiled pipes from top to bottom are set up in parallel, and double heating surface coiled pipe 2 laterally arranges, and hang pipe 1 for many and are vertically set between the double heating surface coiled pipe 2; Coiled pipe does not have impaired boiler heating surface erecting by overhang and also comprises many round steel 7 and a plurality of arcs 8; All have two fixing holes 9 on each arc 8, each arc 8 equal spiral-lock with hang pipe 1 coiled pipe 2 that faces mutually on, many round steel 7 pass fixing hole 9 and coiled pipe 2 is fixed on hangs on the pipe 1.

The specific embodiment two: combine Fig. 1-Fig. 3 that this embodiment is described, the round steel 7 of this embodiment is fixing through welding with the intersection of hanging pipe 1 and fixing hole 9.So be provided with, be convenient to effectively that coiled pipe 2 is fixing.Other composition is identical with the specific embodiment one with annexation.

The specific embodiment three: combine Fig. 1-Fig. 3 that this embodiment is described, the diameter of the round steel 7 of this embodiment is 8mm-15mm.So be provided with, be convenient to effectively that coiled pipe 2 is more fixing.Other composition is identical with the specific embodiment one or two with annexation.
