Abstract
The utility model belongs to the field of cooking ranges and particularly relates to a metal net for collecting heat of a hearth. The metal net is characterized by being formed by mutually interweaving and overlapping 4-10 layers of iron-chromium-aluminum nets with different mesh numbers and diameters. Compared with the prior art, the metal net for collecting the heat of the hearth has the following advantages that the metal net is formed by mutually interweaving and overlapping the iron-chromium-aluminum nets with the different mesh numbers and diameters; the iron-chromium-aluminum nets can conduct heat rapidly so that the heat efficiency of the hearth is improved; the iron-chromium-aluminum nets are not directly contacted with fire and can store the heat by the self temperatures of the cooking ranges, so as to automatically heat the metal net; the heat is reflected into cookware to improve the heat efficiency; the structures and sizes of all the layers of the iron-chromium-aluminum nets are different so as to realize the aim of prolonging the staying time of the heat in the hearth; waste gas is combusted for the second time when the waste gas passes through the iron-chromium-aluminum nets and the heat efficiency is improved; therefore, the emission of the waste gas including CO2 and the like is reduced while the heat efficiency is improved, and the environment-friendly requirements can be met well.
Description
Technical field
The utility model belongs to the cooking stove field, is specially a kind of burner hearth heat build-up wire netting.
Background technology
Large stove is in the market fried kitchen range and the Chinese food frying-oven ubiquity thermal efficiency is low, energy consumption is large problem, and other the discharge of harmful substance such as a large amount of nitrogen oxide, carbon dioxide is arranged, to kitchen staff's health and environment brings and large injury.Fry kitchen range and Chinese food frying-oven generally adopts high temperature resistant cement, refractory brick to form heat-barrier material such as large stove present on market, this material heat-proof quality is poor does not have heat-insulating property also can absorb the increase that heat causes energy consumption, and the utilization rate of heat is low.Also have the kitchen range on present market to adopt honeycomb ceramic plate as Heat Conduction Material, this material is easily broken because often encounter water in actual use, and also easily break in transportation, thereby cause maintenance rate high, it is not strong that cost increases practicality.
The utility model content
For problems of the prior art, the purpose of this utility model is to provide the technical scheme of a kind of burner hearth heat build-up with wire netting.
Described burner hearth heat build-up wire netting, it is characterized in that described wire netting by 4-10 layer mesh number and diameter all not identical ferrum-chromium-aluminum net be interweaved and be formed by stacking.
Described burner hearth heat build-up wire netting, it is characterized in that described wire netting by 7 layers of mesh number and diameter all not identical ferrum-chromium-aluminum net be interweaved and be formed by stacking.
Described burner hearth heat build-up wire netting, the mesh number and the diameter that it is characterized in that described 7 layers of ferrum-chromium-aluminum net are respectively: ground floor mesh number is that 40 orders, diameter are 0.15mm, second layer mesh number is that 40 orders, diameter are 0.2mm, three-layer network order number is that 30 orders, diameter are 0.15mm, four-layer network order number is that 20 orders, diameter are 0.2mm, layer 5 mesh number is that 20 orders, diameter are 0.15mm, layer 6 mesh number is that 30 orders, diameter are 0.15mm, and layer 7 mesh number is that 40 orders, diameter are 0.15mm.
Described burner hearth heat build-up wire netting, is characterized in that the mesh of described ferrum-chromium-aluminum net is shaped as circle, square or polygon.
Described burner hearth heat build-up wire netting, is characterized in that described ferrum-chromium-aluminum net surface coating arranges high-temperaure coating.
The coating of above-mentioned high-temperaure coating can be buied from Beijing will Sheng Weihua chemical industry Co., Ltd.
Compared with prior art, the utlity model has following advantage: wire netting adopt mesh number and diameter all not identical ferrum-chromium-aluminum net be interweaved and be formed by stacking, because the heat conduction of ferrum-chromium-aluminum net is fast, improved the thermal efficiency of burner hearth, the ferrum-chromium-aluminum net is direct contact fire and carry out store heat by self temperature of cooking stove, allow the wire netting automatic heating, reflex to pan and improve the thermal efficiency; Not of uniform size the causing of every one deck ferrum-chromium-aluminum web frame, purpose is to increase the time that heat rests on burner hearth, waste gas allows waste gas burn for the second time during by the ferrum-chromium-aluminum net, improves the thermal efficiency, has reduced CO like this when improving the thermal efficiency
2deng the discharge of waste gas, can be good at reaching the requirement of environmental protection; The ferrum-chromium-aluminum net is high temperature resistant reach 1400 degree and the burner hearth normal temperature at 1300 degree, at ferrum-chromium-aluminum net surface spraying high-temperaure coating, this coating is high temperature resistant reaches 1700 degree, and this coating has function of heat reflection, has protected again the service life of ferrum-chromium-aluminum net; The ferrum-chromium-aluminum netting gear has good crash resistance energy, and practicality is stronger, convenient transportation.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model ferrum-chromium-aluminum net.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail:
Burner hearth heat build-up wire netting, this wire netting by 4-10 layer mesh number and diameter all not identical ferrum-chromium-aluminum net 1 be interweaved and be formed by stacking, the mesh of ferrum-chromium-aluminum net 1 is shaped as circle, square or polygon etc., in order to guarantee the life-span of ferrum-chromium-aluminum net, apply high-temperaure coating is set on ferrum-chromium-aluminum net 1 surface, the coating of high-temperaure coating can be buied from Beijing will Sheng Weihua chemical industry Co., Ltd.
Through the limited number of time experiment, show that 7 layers of ferrum-chromium-aluminum net are optimal case, mesh number and the diameter of 7 layers of ferrum-chromium-aluminum net are respectively: ground floor mesh number is that 40 orders, diameter are 0.15mm, second layer mesh number is that 40 orders, diameter are 0.2mm, three-layer network order number is that 30 orders, diameter are 0.15mm, four-layer network order number is that 20 orders, diameter are 0.2mm, layer 5 mesh number is that 20 orders, diameter are 0.15mm, layer 6 mesh number is that 30 orders, diameter are 0.15mm, and layer 7 mesh number is that 40 orders, diameter are 0.15mm.
Wire netting of the present utility model forms the stove circle of cooking stove together with thermal insulation board, tin platinum plate, and this stove circle is arranged between pan and burner hearth, and wire netting is nearest apart from pan.
The ferrum-chromium-aluminum net that the utility model adopts multiple layer interleaving to arrange is as wire netting, make mesh diminish, there is certain penetrability, and the heat transmission is slow, the thermal efficiency is high, heat utilization ratio reaches more than 75%, and the high temperature in net, can be so that the gas secondary burning, fuel availability improves more than 5 times, reduced the discharge capacity of waste gas, toxic emission is national standard 3/1000ths, holds big lead over the industry other products; The ferrum-chromium-aluminum net surface arranges high temperature coating, not only improves heat reflection, and has extended the shelf life of ferrum-chromium-aluminum net.
