Description

TECHNICAL FIELD

[0001] The utility model belongs to cloth wind structure technical field, concretely relates to a gas stewing pot stove hearth cloth wind structure. BACKGROUND

[0002] The gas stewing pot is the common equipment of traditional marinated meat product old brand enterprise, is used for stewing chicken, duck, pig elbow, pig liver, beef and other meat products. The gas stewing pot is mainly composed of cast iron pot and stove table;The cast iron pot is deep mouth arc bottom, and the pot mouth diameter is 1.2~1.8 meters. The stove table is composed of support steel column, hearth shell, combustion fire plate, peripheral stainless steel fence, and gas inlet pipeline and control system.

[0003] As shown in Figure 1 The cast iron pot is embedded in the stove table, and the lower part is the hearth shell. The hearth shell is two-layer structure: the outer layer is 2~3 millimeter thick cast iron, which plays the role of supporting the inner lining layer;The inner lining layer is a certain thickness of refractory cement layer, which is used for heat preservation and heat dissipation. The cavity formed between the hearth shell and the cast iron pot is the hearth. The fire plate is located in the middle opening at the bottom of the hearth, and the natural gas and air are ignited and burned at the fire plate;The high temperature flame contacts the cast iron pot bottom through the hearth, and the heat is transferred to the cast iron pot, so as to carry out meat stewing processing. The rear side of the stove hearth is the smoke exhaust duct, which is connected with the factory negative pressure exhaust duct, and the flue gas can be actively sucked out of the hearth.

[0004] In the daily production process of the gas stewing pot, because the hearth and the smoke exhaust duct are not separated, a shortest channel is formed between the fire plate and the smoke exhaust duct. The high temperature flue gas generated by natural gas combustion is quickly discharged from the hearth along the shortest channel after short contact with the cast iron pot, thereby causing some adverse consequences:

[0005] 1. The high temperature flue gas contacts the cast iron pot bottom for a short time, and the heat is not fully absorbed by the cast iron pot before being discharged from the hearth, resulting in high exhaust temperature, high heat loss of flue gas, and low heat efficiency of the gas stewing pot;

[0006] 2. Most of the high temperature flue gas is discharged from the hearth along the shortest channel, causing uneven heating of the cast iron pot near the shortest channel and other parts.

[0007] 3. Due to insufficient heat utilization, the flue gas temperature in the exhaust duct is too high, resulting in serious burning loss of the outer wall of the flue duct.

[0008] Therefore, the wind field structure in the hearth of the gas stewing pot is unreasonable, and the existing wind field has the disadvantages of low heat efficiency, uneven heating and burning loss of the outer wall of the exhaust duct. It is necessary to improve the wind field structure. The gas stewing pot is a device with high energy consumption in enterprises, and its structure improvement can improve its energy efficiency, which has economic significance for marinated meat product enterprises.
