Abstract
The utility model provides a dual-layer hollow cast steel combustion chamber structure of a Chinese food stove. The overall structure is circular, both the side edge and the bottom of the structure adopt hollow cast steel structures, and the structure comprises a combustion chamber outer wall, a hollow gas circulation cavity and a combustion chamber inner wall from outside to inside. The structure is characterized in that side surfaces of both the combustion chamber outer wall and the combustion chamber inner wall are in arc shapes longitudinally; a high-temperature fire-proof cotton liner attached to the combustion chamber inner wall is arranged on the inner side of the combustion chamber inner wall; the bottom of the combustion chamber inner wall is connected with a combustion chamber flange through a turnbuckle hole; a plurality of inner wall vent holes are formed in the side surface of the combustion chamber inner wall; and a downward outer wall lower vent hole is formed in the bottom of the combustion chamber outer wall. Compared with the prior art, the structure has the advantages of good fire-proof and heat-insulating performance, high heat energy utilization rate, convenience in matched installation and capability of reducing hot gases and harmful gases discharged to an operating room and improving the comfort level of the operating room of a kitchen.
Description
Technical field
The utility model relates to kitchen range technical field, relates in particular to a kind of double layer hollow cast steel chamber structure of Chinese meal kitchen range.
Background technology
The kitchen range that Chinese meal is used are had relatively high expectations to specified heat flow, are generally not less than 35kW, generally use fuel oil or combustion gas as fuel, in traditional Chinese meal kitchen range, burner hearth is used refractory cement and laying fireproof bricks to form mostly, and burner hearth overall weight is large, artificial masonry quality is difficult for controlling, and the effort of taking a lot of work; Main furnace chamber is straight-through up and down can not play poly-fiery effect, and heat insulation effect is poor, and calorific value loss is large, easily causes fuel combustion not to the utmost, forms too much CO gas, wastes energy.In existing burner hearth product, also there is casting burner hearth, but exist a lot of shortcomings, for example: be mostly hearth body and the casting of inlet plenum one, be unfavorable for the installation of burner, hearth wall adopts straight plate to tilt, and flame is directly roasted burner hearth arm, easily causes stove and accessory to damage too early, waste gas circulation air inlet and gas outlet irrational distribution, easily cause back of house environmental pollution.
Given this, be necessary to provide a kind of new chamber structure to solve above-mentioned technical problem.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of double layer hollow cast steel chamber structure of new Chinese meal kitchen range, it utilizes casting double-layer alloy steel construction, install the fire resistant heat preserving boll hull layer of die cast additional, flange is set in bottom and combustor is direct-connected, can greatly improve the efficiency of utilization of fuel, produces waste gas few, firing rate is fast, energy-conserving and environment-protective, easy installation and removal, is convenient to safeguard.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of double layer hollow cast steel chamber structure of Chinese meal kitchen range, integral body is annular, its side and bottom are hollow cast steel structure, ecto-entad comprises hearth outer wall, hollow gas circulation chamber, inboard wall of burner hearth, it is characterized in that: the lateral longitudinal of described hearth outer wall and inboard wall of burner hearth is to being circular arc, and the inner side of inboard wall of burner hearth is provided with the cotton inner bag of the high-temperature flame-proof attaching with inboard wall of burner hearth.
As the further improvement of the technical program, the bottom of described hearth outer wall and inboard wall of burner hearth is provided with the screw button hole of perforation, by screw button hole, is connected with a burner hearth flange.Burner hearth flange can with the supporting making of combustor, burner hearth flange and combustor flange are combined closely, change original connected structure, good sealing effect, easy for installation.
As the further improvement of the technical program, the side of described inboard wall of burner hearth, is being provided with along the equally distributed a plurality of inwall steam vents of annular higher than place, the cotton inner bag of high-temperature flame-proof top, and the bottom of described hearth outer wall is provided with steam vent under downward outer wall.When pot in the above time burner hearth approach closed state, burning hot gas in burner hearth can only flow to hollow gas circulation chamber from inwall steam vent, allow the gas with heat energy circulate in hollow gas circulation chamber, continuation is heated to burner hearth, waste gas is discharged downwards by steam vent under outer wall, the principle of utilizing hot gas to rise, then return to position, the bottom of a pan, reduced the waste of heat energy.
Compared with prior art, the double layer hollow cast steel chamber structure of the utility model Chinese meal kitchen range, utilizing is longitudinally the burner hearth sidewall of circular arc, make combustion gas mixing air and circle round in burner hearth, fully burning, the calorific value that allows pot absorb is larger; When the cotton inner bag of high-temperature flame-proof of inboard wall of burner hearth has fire resistant heat preserving function, can also be by most of reflect radiation heat to the bottom of a pan, improved heat utilization rate, flange form syndeton, make burner hearth supporting easier for installation, hollow hot-fluid cyclic part, in conjunction with steam vent under downward outer wall, has reduced heat-energy losses, has improved the comfort level of back of house.
Accompanying drawing explanation
Fig. 1 is the generalized section of the double layer hollow cast steel chamber structure of Chinese meal kitchen range described in the utility model.
Fig. 2 is the top view of the double layer hollow cast steel chamber structure of Chinese meal kitchen range described in the utility model.
The specific embodiment
Refer to shown in Fig. 1 to Fig. 2, the utility model provides a kind of double layer hollow cast steel chamber structure of Chinese meal kitchen range, integral body is annular, its side and bottom are hollow structure, ecto-entad comprises hearth outer wall 1, hollow gas circulation chamber 2, inboard wall of burner hearth 3, the lateral vertical direction of described hearth outer wall and inboard wall of burner hearth is circular arc, the inner side of inboard wall of burner hearth 3 is provided with the cotton inner bag 4 of high-temperature flame-proof, the bottom of described hearth outer wall and inboard wall of burner hearth is provided with the screw button hole of perforation, by screw button hole, be connected with a burner hearth flange 5, the side of described inboard wall of burner hearth, higher than place, the cotton inner bag of high-temperature flame-proof top, be provided with along the equally distributed a plurality of inwall steam vents 6 of annular, the bottom of described hearth outer wall is provided with steam vent 7 under downward outer wall.
During use, the flange of combustor is connected with burner hearth flange 5, combustor oil spout or gas ejecting system are lighted after fuel is mixed with air, through burner hearth flange 5, send into burner hearth internal combustion, and the gas of burning impacts arc hearth wall and the cotton inner bag of high-temperature flame-proof, form the air-flow of rotation, fully, after burning, waste hot gas enters hollow gas circulation chamber 2 by inwall steam vent 6, and heat energy is continued to pass to burner hearth arm, then by steam vent under outer wall 7, discharged, the cotton inner bag 4 of high-temperature flame-proof plays reflective insulation function.
The above; it is only most preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction; any those of ordinary skill in the art; do not departing from technical solutions of the utility model scope situation; utilize the method content of above-mentioned announcement to make many possible changes and modification to technical solutions of the utility model, all belong to the scope of claims protection.
