Description

The anti-fiery heating stove of a kind of novel straight burning

Technical field:

The utility model relates to a kind of heating stove.

Background technology:

Multiple recirculated water warming stove is arranged in the market, but the most of thermals efficiency of these warming stoves are relatively very low, thermal conversion efficiency has only 30%-40%, has wasted a large amount of energy, is unfavorable for building a conservation-minded society.But also have the higher structure of some warming stove thermals efficiency very complicated, manufacturing cost is very high, and also because complex structure in use should not keep in repair, and service life is short, use cost is also very high simultaneously.

The utility model content:

The utility model has designed the anti-fiery heating stove of a kind of novel straight burning, and it has the thermal conversion efficiency height, and is simple in structure, saves manufacturing cost, the advantage of long service life.The utility model is made up of body of heater 1, chimney 2, flue 3, and chimney 2 is arranged on the upper end cover of body of heater 1, and flue 3 is fixed on the inside of body of heater 1, and flue 3 stretches out body of heater 1 by water inlet 4 and delivery port 8 and flue 3 is fixed on the inside of body of heater 1.Described flue 3 is made up of delivery port 8, tabular water tank 9, water inlet straight tube 11, mistake water ring 10, flue urceolus 7, flue inner core 6, inlet channel 5, water inlet 4, delivery port 8 be fixed on flue urceolus 7 the top the top and delivery port 8 is connected with tabular water tank 9, the welding of water inlet straight tube 11 and be fixed on tabular water tank 9 below; The cylindric two ends of crossing water ring 10 cylinders are fixed on the into two ends of water straight tube 11, flue inner core 6 was fixed on the outside of water ring 10, inlet channel 5 is fixed on the side of outer wall of flue inner core, water inlet 4 is fixed on the lower end of inlet channel 5 and is connected with inlet channel 5, and the opposite side of the inlet channel 5 of flue inner core 6 is provided with coal filling hole 12.Hot cigarette in the utility model circulates in flue and walks about, and provides high thermal conversion efficiency; And the water chamber excessively in the utility model reaches four and is inlet channel 5, mistake water ring 10, water inlet straight tube 11, tabular water tank 9, has improved the thermal process that is subjected to of water greatly, has improved thermal conversion efficiency; The utility model is simple in structure, has reduced manufacturing cost; Because working service simple in structure is all very convenient, also prolonged service life simultaneously, suit to be applied to build a conservation-minded society.

Description of drawings:

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the structural representation of the utility model stove tube inner bag 3, and Fig. 3 is that the A-A of Fig. 2 is to view.

The specific embodiment:

As Figure 1-3, this specific embodiment is made up of body of heater 1, chimney 2, flue 3, chimney 2 is arranged on the upper end cover of body of heater 1, and flue 3 is fixed on the inside of body of heater 1, and flue 3 stretches out body of heater 1 by water inlet 4 and delivery port 8 and flue 3 is fixed on the inside of body of heater 1.Described flue 3 is made up of delivery port 8, tabular water tank 9, water inlet straight tube 11, mistake water ring 10, flue urceolus 7, flue inner core 6, inlet channel 5, water inlet 4, delivery port 8 be fixed on flue urceolus 7 the top the top and delivery port 8 is connected with tabular water tank 9, the welding of water inlet straight tube 11 and be fixed on tabular water tank 9 below; The cylindric two ends of crossing water ring 10 cylinders are fixed on the into two ends of water straight tube 11, flue inner core 6 was fixed on the outside of water ring 10, inlet channel 5 is fixed on the side of outer wall of flue inner core, water inlet 4 is fixed on the lower end of inlet channel 5 and is connected with inlet channel 5, and the opposite side of the inlet channel 5 of flue inner core 6 is provided with coal filling hole 12.In this specific embodiment, coal makes progress away at flue inner core 6 internal combustion flames and hot cigarette, walk downwards by crossing the inside that space between water ring 10 and the tabular water tank 9 arrives the outside-flue urceolus 7 of flue inner core 6, discharge by chimney 2 by the outside of flue urceolus 7 at last.Cold water enters inlet channel 5 by water inlet 4 and passes through inlet channel 5 arrival water inlet straight tubes 11, crosses water ring 10 and tabular water tank 9, and cold water all can be heated in these four cavitys, and the water after the heating makes progress and passes through delivery port 8 and export.This specific embodiment has improved the heating surface area of water greatly, has improved thermal conversion efficiency; The utility model is simple in structure, has reduced manufacturing cost; Because working service simple in structure is all very convenient, also prolonged service life simultaneously.
