Abstract
The utility model discloses a master-auxiliary hot water furnace which is jointed by two cylinder inner and outer furnaces with different size and an outer ring water tank is formed between the two furnaces. The inner furnace center is provided with a cylinder circle inner water tank of full seal. The upper and the lower end of the inner water tank are respectively communicated with the inner and the outer circle water tanks through a connecting water tube. A circle outer fire cavity is formed between the inner circle water tank and the inner furnace. The inner circle water tank center has an inner circle fire cavity. The heat exchange area between two fire cavities and the two circle water tanks is large with high efficiency and fast speed of burning water. When the furnace is under unpressurized operation, the safe valve guarantees safety and reliability of the furnace. Water level in the furnace is observed through a water level tube and water is added at any moment to avoid dry burn.
Description
Technical field
The utility model relates to a kind of water heater.
Background technology
The at present fire coal that uses, the water heater of combustion gas because the stove fire that fire box produces directly enters flue, with the contact area of water in the body of heater be that heat exchange area is little, heat exchange is insufficient, the thermal efficiency is low, is embodied in the expense coal, hot water heats up slow.
Summary of the invention
The purpose of this utility model provides a kind of thermal efficiency height, the primary-secondary type water heater that heat exchange area is big, it is at garden cylindricality external furnace body inner chamber less garden cylindricality inner furnace body of suit again, the full-closed ring inner water tank is installed at the body of heater center, thereby form inside and outside two annular water tanks and inside and outside two stove fire chambeies, two water tanks two ends connection cross current up and down.Stove fire in the burner hearth enters chimney through inside and outside two stove fire chambeies.
The utility model is realized with following technical scheme: a kind of primary-secondary type water heater comprises body of heater, chimney, burner hearth, fire grate, coal port, ash hole.It is characterized in that: the arc lid central vertical of described garden cylindricality external furnace body upper end is chimney fixedly, and safety valve is installed in the external furnace body upper end and connects with the outer shroud water tank; Garden cylindricality inner furnace body is sleeved on the inner chamber of external furnace body, the arc lid of its upper end and the lower end welding and the perforation of chimney; By garden cylindricality inner water tank outer wall and inner water tank inwall and up and down end cap be welded into annular tube shaped totally-enclosed in the ring water tank be sleeved on the inner chamber of inner furnace body, interior ring water tank upper and lower side connects water pipes and inner furnace body welding and perforation by two respectively; Make coal port on garden, the bottom cylinder of external furnace body and inner furnace body, the bottom rigid grate of coal port, the bottom of fire grate makes ash hole; The water filling water tank is installed in a upper lateral part of external furnace body and is connected with the bottom of external furnace body and connects by water pipe, and discharging valve is installed by threeway in the bottom of water pipe; Water level pipe is vertically mounted on a side of external furnace body and connects with the outer shroud water tank.
Good effect of the present utility model is:
1, owing to inside and outside two annular water tanks and the cross arrangement of inside and outside two stove fire thoraxes, the long-pending face of hot cross surface is big, and hot and cold water circulates in two annular water tanks, circulates.Facts have proved the boiling water of boiled same volume, economize on coal 30% than monomer water heater of the same type, the time shortens 20%.
2, there is not the manufacture hot water of pressure, safe and reliable.
3, burner hearth and chimney dust stratification are few, and dust stratification is cleared up easily.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, chimney, 2, safety valve, 3, the water filling water tank, 4, water pipe, 5, external furnace body, 6, the outer shroud water tank, 7, inner furnace body, 8, outer shroud stove fire chamber, 9, the inner water tank outer wall, 10, interior ring water tank, 11, discharging valve, 12, connect water pipe, 13, burner hearth, 14, ash hole, 15, fire grate, 16, coal port, 17, water level pipe, 18, the inner water tank inwall, 19, interior stove fire chamber.
The specific embodiment
As shown in drawings, the matrix water heater comprises body of heater, chimney, burner hearth, fire grate, coal port, ash hole.It is characterized in that: the arc lid central vertical of cylindricality external furnace body 5 upper ends, described garden is chimney 1 fixedly, and safety valve 2 is installed in external furnace body 5 upper ends and connects with outer shroud water tank 6; Garden cylindricality inner furnace body 7 is sleeved on the inner chamber of external furnace body 5, the arc lid of its upper end and the lower end welding and the perforation of chimney 1; By garden cylindricality inner water tank outer wall 9 and inner water tank inwall 18 and up and down end cap be welded into annular tube shaped totally-enclosed in ring water tank 10 be sleeved on the inner chamber of inner furnace body 7, interior ring water tank 10 upper and lower sides connect water pipes 12 with inner furnace body 7 welding and connect by two respectively; Make coal port 16 on garden, the bottom cylinder of external furnace body 5 and inner furnace body 7, the bottom rigid grate 15 of coal port 16, the bottom of fire grate 15 makes ash hole 14; Water filling water tank 3 is installed in a upper lateral part of external furnace body 5 and is connected with the bottom of external furnace body 5 and connects by water pipe 4, and the bottom of water pipe 4 is by threeway installation discharging valve 11; Water level pipe 17 is vertically mounted on a side of external furnace body 5 and connects with outer shroud water tank 6.
As accompanying drawing institute, during use water is injected from water filling water tank 3, enter the outer shroud water tank 6 that forms by between external furnace body 5 and the inner furnace body 7 by water pipe 4, enter interior ring water tank 10 by connecting water pipe 12 again.Discharge from chimney 1 in stove fire chamber 19 and outer shroud stove fire chamber 8 in stove fire in the burner hearth 13 enters simultaneously again.Stove fire heats the water in outer shroud water tank 6 and the interior ring water tank 10 simultaneously, and heat exchange area is big, thermal efficiency height.Two connection water pipes 12 make inner and outer rings water tank 10,6 produce convection current up and down, make the water temperature of two water tanks keep balance, more favourable heat exchange.
The effect inspection box middle water level of water level pipe 17 adds water at any time, in case the body of heater dry combustion method.
The effect of safety valve 2 prevents body of heater inner vapor hypertonia, guarantees body of heater and personal safety.
As required, can install incubator additional around the utility model primary-secondary type water heater.
