Abstract

The utility model discloses an integration heat accumulation nozzle, middle part symmetrical ring package has two semi -circular heat preservation casings on firing tracheal circumference outer wall, at the heat preservation casing inner gap heat accumulator of having arranged, use the gas pipe as the center outstanding semi -circle dual -purpose passageway of exhaust that admits air that is equipped with respectively forward at the front end of each heat preservation casing, gas pipe front end between two dual -purpose passageways is equipped with the bocca, it has two exhaust chambers that admit air to fit with a contraceptive ring the package at the gas outside of tubes wall of the rear end of each heat preservation casing, be equipped with the gas vent that admits air respectively on the exhaust outdoor wall that respectively admits air, the gas is intraductal install the outer wall with centre of a circle clearance fit on the equipartition have the core pipe of air vent, the gas mixing chamber is installed to outer end two dual -purpose rooms of exhaust of admitting air, be equipped with cold state gas import at the mixed outdoor end of gas, be equipped with hot gas import and cold state air intlet respectively on gas mixing chamber lateral wall. Have small, cost of manufacture low, be suitable for to install and use in small -size stove very much.

Description

Integration heat-accumulating burner

Technical field:

This utility model be a kind of for be arranged in stove, workpiece is heated time use integrated heat-accumulating burner.

Background technology:

The heat-accumulating burner installed and used in stove at present, it is all to be mounted opposite in heated workpiece both sides by two heat-accumulating burner firn-jet heads, alternate and workpiece is heated, each heat-accumulating burner is to be provided with a bocca at the outlet port of a Gas Pipe, the circumferential wall of Gas Pipe is provided with the exhaust gases passes that circle two ends are the most penetrating, in exhaust gases passes, is evenly equipped with the heat storage of gap discharge.This split type heat-accumulating burner is in use, first burn to workpiece heat with a bocca, in the exhaust gases passes of the heat-accumulating burner that the high-temperature flue gas that the flame simultaneously heated produces enters into opposite side, heat storage therein is preheated, both the flame ignition of another heat-accumulating burner had been facilitated, take full advantage of again waste heat, but the major defect existed is that volume is big, manufacturing cost is high, it is only suitable for large-scale stove and uses, be not suitable for being arranged on use on small-sized stove.

Summary of the invention:

The purpose of this utility model is to provide that a kind of volume is little, low cost, be suitable for the integrated heat-accumulating burner installed and used on various stoves.

nullThe technical solution of the utility model completes as follows，Integration heat-accumulating burner，It includes a Gas Pipe，It is characterized in that: in the outer circumferential walls of Gas Pipe, middle part symmetrical ring is surrounded by two semicircle insulation shells，It is placed with heat storage at insulation shell internal clearance，Highlight forward centered by Gas Pipe in the front end of each insulation shell and be respectively equipped with a dual-purpose passage of semicircle air intake-exhaust，Gas Pipe front end between two dual-purpose passages is provided with a bocca，On the Gas Pipe outer wall of the rear end of each insulation shell, ring is surrounded by two air intake-exhaust rooms，Each air intake-exhaust chamber outer wall is respectively equipped with an air intake-exhaust mouth，In Gas Pipe, concentric matched in clearance is provided with the core pipe being evenly equipped with passage on an outer wall，In the outer end of two dual-purpose rooms of air intake-exhaust, one gas mixing chamber is installed，A cold conditions fuel gas inlet it is provided with in gas mixing chamber outer end，Gas mixing chamber's sidewall is respectively equipped with a hot fuel gas inlet and a cold conditions air intlet.

This utility model has that volume is little, cost of manufacture is low, particularly suitable be arranged on small-sized stove in use.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention:

nullEmbodiment is described in detail in conjunction with accompanying drawing，It includes a Gas Pipe 11，In the outer circumferential walls of Gas Pipe, middle part symmetrical ring is surrounded by two semicircle insulation shells 6，It is placed with heat storage 7 at insulation shell internal clearance，Highlight forward centered by Gas Pipe in the front end of each insulation shell and be respectively equipped with a dual-purpose passage of semicircle air intake-exhaust 8，Gas Pipe front end between two dual-purpose passages is provided with a bocca 9，On the Gas Pipe outer wall of the rear end of each insulation shell, ring is surrounded by two air intake-exhaust rooms 4，Each air intake-exhaust chamber outer wall is respectively equipped with an air intake-exhaust mouth 5，In Gas Pipe, concentric matched in clearance is provided with the core pipe 10 being evenly equipped with passage on an outer wall，One gas mixing chamber 2 is installed in the outer end of two air intake-exhaust rooms，A cold conditions fuel gas inlet 1 it is provided with in gas mixing chamber outer end，Gas mixing chamber's sidewall is respectively equipped with a hot fuel gas inlet 3 and a cold conditions air intlet 12.Its operation principle is, when bocca flame combustion by one of them air intake-exhaust mouth air inlet, gas flows into dual-purpose passage in entering insulation shell after heat storage preheats, at bocca, burned flame is carried out combustion-supporting, most of high-temperature flue gas after burning is then entered second half insulation shell by the dual-purpose passage of another side and preheats heat storage therein, is then discharged in chimney by the flue gas after cooling through another air intake-exhaust mouth.So by two semicircle insulation shell alternations, it is achieved energy-saving and emission-reduction, so this utility model has, volume is little, conveniently install and use, and is particularly suitable on small-sized stove application.
