Description

A kind of hot-blast stove

Technical field:

The utility model relates to the equipment that a kind of hot house of using to arviculture and livestock and poultry breeding industry is heated.

Background technology:

Existing being the hot-blast stove of RFL1000 ㎡ to the heat model used of hot house, highly is 1.5 meters, and length is 2.0 meters, and width is 0.76 meter; Because its furnace wall is an individual layer, so heat insulation effect is bad, heat loss in the process of conduction is big; The Guan Yiduan that heats of bottom is communicated with flue in the hot-blast stove; The other end is communicated with the combustion chamber, and the Guan Yiduan that heats of hot-blast stove internal upper part is communicated with flue, and the other end is communicated with smokejack; Because the width of flue is 300mm; So it is less to heat the length of pipe, air is less with the heat exchange area that heats pipe, and heat utilization efficiency is low.

Summary of the invention:

The utility model technical problem to be solved provide a kind of heat in conductive process, lose little, the hot-blast stove that heat utilization efficiency is high.

Above-mentioned purpose be achieved in that with have now hot-blast stove identical be that it also comprises the furnace wall, there is flue at the rear portion in the body of heater, the back shoot door on the furnace wall is connected with flue; There is dreg chamber the front portion in the body of heater, and there is grate the dreg chamber top, and the grate top is the combustion chamber; Have coal-filling hole to be connected with the combustion chamber on the furnace wall, several fresh air inlets are arranged on dreg chamber's rear wall, an end of air door control lever is contained on the furnace wall and stretches out outside the furnace wall; The other end is contained near the dreg chamber's rear wall the fresh air inlet, is positioned on the air door control lever of dreg chamber's rear wall one end air door is housed, needed air capacity adjustment air door in the time of can be according to burning; Have cleanout door to be connected with dreg chamber on the furnace wall, there is smokejack the top, combustion chamber, has outlet flue to be connected with smokejack on the furnace wall; Have preceding shoot door to be connected with smokejack on the furnace wall, formed space is to heat the air channel between body of heater inner flue and upper furnace wall, following furnace wall, combustion chamber, smokejack and the dreg chamber, and heating has some to heat pipe in the air channel; An end that heats pipe that wherein is positioned at the bottom is connected with the combustion chamber, and the other end is connected with flue, and a superposed end that heats pipe is connected with flue; The other end is connected with smokejack; On the furnace wall of flue below air inlet is arranged, hot-blast outlet is arranged at the top, furnace wall, hot-blast outlet and air inlet all with heat the air channel and be connected; Internal protecting wall is set up in the inboard of the furnace wall that different is our furnace wall, top and furnace wall, two sides and the combustion chamber in body of heater is anterior, is filled with insulation material between internal protecting wall and the furnace wall.

Described flue width is 100mm.

The utility model has the advantages that: because internal protecting wall has been set up in the inboard of the furnace wall of upper furnace wall in body of heater and furnace wall, two sides and front portion, combustion chamber; Be filled with insulation material between internal protecting wall and the furnace wall; So it is little that high insulating effect, heat are lost in conductive process; In addition owing to the width with flue is reduced to 100mm; The length that heats pipe has just increased 200mm; So heat pipe and the heat exchange area that heats the air in the air channel with the hot-blast stove phase specific energy increase of identical overall dimensions (model is RFL1000 ㎡); Can increase by the heat exchange area of 200 ㎡, so model changes RFL1200 ㎡ into.

Description of drawings:

Accompanying drawing is the structural representation of the utility model.

The specific embodiment:
