Description
Technical field
A kind of heating arrangement of electric boiler is the utility model is related to, specifically, the utility model is related to a kind of directly-heated type
Electric boiler isothermal heating arrangement.
Background technology
With the progress of society, economic growth, city size increasingly expands, and thus also produces a series of social concerns,
The problem of wherein most disturbing people is atmosphere pollution.In recent years, government is increased to urban atmospheric pollution renovation dynamics, takes blue law
Regulation controls pollution sources, and explicit order selected group unit uses miniature coal, fuel-oil water heater or boiler, promotion uses electric boiler
Or gas heater.The grill pan furnace structure of prior art is very simple, small volume, blowdown are few, disclosure satisfy that electric boiler updates
It is required that.The electric boiler electrical heating elements of prior art are located at water tank bottom, and this structure makes full use of hot ascension principle, realizes in case
Purpose is uniformly heated in water storage.But big specification electric boiler heat conduction path length, collects mid-term because volume is big, reservoir storage is big in water intaking
Because electrically heated heat conduction of velocity is unable to catch up with moisturizing speed, electric boiler top and the bottom water temperature problem of non-uniform, this situation are easily caused
Have a strong impact on quality of water supply, it is impossible to meet the requirement of user.
Utility model content
The utility model mainly for prior art electric boiler the particular time quality of water supply difference the problem of, propose a kind of
It is simple in construction, heating element heater is rationally distributed, the thermal efficiency is high, even water temperature is good in case directly-heated type electric boiler isothermal heating knot
Structure.
The utility model is achieved through the following technical solutions technical goal.
Directly-heated type electric boiler isothermal heating arrangement, it include casing, electrothermal tube, thermocouple, outlet valve, water intaking valve, water pump,
Water-level gauge and water check valve.The casing is the closed container for having heat-insulation layer, is configured on the outer wall of side by outlet valve and water level
Meter composition outlet system, water system is formed by water intaking valve and water check valve.It is theed improvement is that：The electrothermal tube is tubulose structure
Part, it is same to assemble the electric heating tube power put along the same side wall of the casing electrothermal tube that from bottom to top two groups of spacing of radial direction interpolation do not wait
Identical, it is 3 often to assemble and put electrothermal tube quantity, and tactic two groups of heating tubes form cabinets cavity bottom and middle part is common
Heating arrangement.The water pump is placed on cabinet exterior, and the inlet and outlet of water pump links up casing by institute's connecting pipe respectively
Inner chamber, the hot water for forming bottom half continue structure for conveying upwards.The thermocouple is assigned on wall box, and particular location exists
Between two groups of electrothermal tubes.
As further improvement project, the electrothermal tube is spaced, and an electrothermal tube of the following group bottommost is away from casing
The vertical range H at bottom1=100~150mm, phase spacing H between the electrothermal tube of the following group2=150~250mm, upper the following group adjacent spacing
H3=250~350mm, alternate H between upper group of electrothermal tube4=260~360mm.
As further improvement project, the water pump is centrifugal peripheral pump.
The utility model compared with prior art, has the positive effect that：
The utility model one is to use electric heating device, and heating is fast, non-pollution discharge；Second, followed using pump operation is configured
Ring function, improve the rate of heat exchange of electric boiler, promote isothermal heating.
Brief description of the drawings
Fig. 1 is the utility model structure half-section diagram.
Embodiment
Below according to accompanying drawing and in conjunction with the embodiments, the utility model is described in further detail.
The isothermal heating arrangement of directly-heated type electric boiler shown in Fig. 1, it including case stop 1, electrothermal tube 2, thermocouple 3, outlet valve 4,
Water intaking valve 5, water pump 6, water-level gauge 7 and water check valve 8.The casing 1 is to have the closed cylindrical container of heat-insulation layer, outside side
Configuration forms outlet system by outlet valve 4 and water-level gauge 7 on wall, and water system is formed by water intaking valve 5 and water check valve 8.The electricity
Heat pipe 2 is tubular element, is placed in suspended wall shape in the side wall of casing 1.In order to realize that isothermal heats purpose, the utility model is first
Curve guide impeller is first done on heating arrangement, using electric heating device, along 1 same side wall of casing from bottom to top two groups of radial direction interpolation
The electrothermal tube 2 that spacing does not wait, same to assemble the power of electrothermal tube 2 put identical.The present embodiment volume is 10.0m3, supporting power supply is
380V civil powers, therefore often assemble that to put the quantity of electrothermal tube 2 be 3, two groups of installation sites of electrothermal tube 2 make it is following arrange, the following group most bottom
Vertical range H of piece electrothermal tube 2 in portion away from bottom in casing 11=100mm, phase spacing H between the electrothermal tube 2 of the following group2=
200mm, upper and lower two groups of adjacent spacing H3=300mm, alternate H between upper group of electrothermal tube 24=300mm.Another heating arrangement be
Water pump 6 is disposed on the outer wall of casing 1, the inlet and outlet of water pump 6 links up the inner chamber of casing 1 by institute's connecting pipe 6.1 respectively.This reality
It is a kind of centrifugal peripheral pump to apply the supporting water pump 6 of example, and such pump anti-cavitation ability is strong, particularly suitable for hot water delivery.For
Electric boiler heating-up temperature can be objectively responded, supporting thermocouple 3 is assigned between two groups of electrothermal tubes 2 up and down.Because of volume
Greatly, in order to improve the uniformity of water temperature, the utility model configuration water pump 6, the operating of water pump 6 can be stirred in directly-heated type electric boiler
Water, internal water circulation are advantageous to improve the rate of heat exchange of electric boiler, can directly reduce the temperature difference of the inner chamber top and the bottom of casing 1, from
And improve electric boiler quality of water supply.
