Abstract

The utility model relates to a domestic boiler with a water tank surrounding the hearth, and comprises a furnace cover, a furnace body, a furnace bottom shell, a hearth, a vent-pipe, a water inlet pipe, a water outlet pipe, and a flame band bridge; wherein, the hearth is vertically arranged in the furnace; the vent-pipe is arranged in the lower part of the hearth; the outer wall, the inner wall of the furnace, the furnace cover and the furnace bottom shell are enclosed into a close water tank; the lower part of the vent-pipe at the bottom of the water tank is connected with the water inlet pipe. The utility model has the advantages of better pyrometric effect because of making use of heat energy in a better way, steady exchanging between hot water and cold water, thereby being an ideal domestic boiler.

Description

Air preheat burning-assist water heater
Technical field: but the utility model relates to the cooking stove of the heat supply water of a kind of family use, and particularly surrounding burner hearth with water tank is the back boiler of feature.
Background technology: general back boiler is the vertical burner hearth cylindrical shell of placing, pass the water tank cylindrical shell of horizontal placement, such back boiler, though when burning coal, water in also can heating water tank, but its thermal efficiency is not high, and hot water or cold water's exchange is also disorderly in the water tank, brings inconvenience to the user.
Summary of the invention: technical problem to be solved in the utility model provides a kind of thermal efficiency height, and hot water or cold water's exchange current adopts the combustion-supporting water heater of air preheat to stable novel high-efficiency and energy-saving.
The utility model solves its technical problem and adopts following technical scheme:
The utility model is by bell, body of heater, burner hearth, bearth shell, ventilation duct, water inlet pipe, outlet pipe, grate, heat-insulation layer is formed, burner hearth vertically is positioned in the body of heater, hearth outer wall and inboard wall of furnace body and bell, bearth shell surrounds the water tank of a sealing, ventilation duct passes body of heater and is connected with burner hearth, and communicate with burner hearth by grate, space between ventilation duct and the grate constitutes air preheating chamber, space between ventilation duct and burner hearth and the bearth shell constitutes heat-insulation layer, the below of water tank bottom ventilation duct is connected to water inlet pipe, the top of water tank opposite side is connected to outlet pipe, and the outlet pipe top is an angular cut.
The utility model is because burner hearth is vertically to be positioned in the body of heater, and ventilation duct is to pass body of heater to be connected with burner hearth, the coal of burner hearth burning can heat the water in the water tank like this, the water of heating is incubated for again burner hearth better, enter the unofficial biography effect of the water that the air in the ventilation duct heats in air preheating chamber is subjected to water tank, become hot blast, make the coal combustion in the burner hearth better, when opening water inlet pipe and outlet pipe, enter the cold water (certain pressure is arranged) of water inlet pipe owing to be subjected to stopping of ventilation duct, form the bottom of contrajet to water tank, the cold water pressure effect that hot water is risen by balance, by the angular cut inflow outlet pipe of top outlet pipe, the angular cut of outlet pipe can guarantee when being full of water in the water tank, hot water flows out from tank top, and makes hot and cold water and exchange current to stable.
Can place insulation material in the heat-insulation layer, burn better to guarantee the coal in the burner hearth.
The utility model energy-saving effect is remarkable, and heat utilization efficiency is complete, and the hot and cold water exchange is not disorderly, simple in structure, can live or the shower of heat supply water for people from the hot water that outlet pipe flows out, and is convenient feasible.
Description of drawings:
Fig. 1 is the utility model master cutaway view.
Fig. 2 is the utility model vertical view.
The specific embodiment: as shown in Figure 1, 2.The utility model is by bell 11, body of heater 1, burner hearth 2, bearth shell 13, ventilation duct 7, water inlet pipe 6, outlet pipe 5, grate 12, heat-insulation layer 8 is formed, burner hearth 2 vertically is positioned in the body of heater 1, hearth outer wall 4 and inboard wall of furnace body 3 and bell 11, bearth shell 13 surrounds the water tank 9 of a sealing, ventilation duct 7 passes body of heater 1 and is connected with burner hearth 2, and communicate with burner hearth 2 by grate 12, space between ventilation duct 7 and the grate 12 constitutes air preheating chamber 10, space between ventilation duct 7 and burner hearth 2 and the bearth shell 13 constitutes heat-insulation layer 8, the below of water tank 9 bottom ventilation ducts 7 is connected to water inlet pipe 6, the top of water tank 9 opposite sides is connected to outlet pipe 5, and outlet pipe 5 tops are angular cut.
Body of heater 1 of the present utility model, bell 11, bearth shell 13 adopt stainless steel or aluminium alloy, and body of heater 1 can adopt vertical ellipsoid or vertical type cylinder body, and burner hearth can adopt single burner hearth, twin furnace or multiple hearth.
