A kind of shunting moisturizing pot sheet
Technical field
The utility model relates to cast-iron boiler sheet, relates in particular to a kind of shunting moisturizing pot sheet.
Background technology
Cast-iron boiler is because of its corrosion resistant, long service life and being favourably welcome, the ring-shaped water jacket structure is adopted in the bottom of the pot sheet of traditional cast-iron boiler, the hollow cavity internal combustion that flame surrounds at ring-shaped water jacket, formed a kind of structure of water bag fire, the mode that the water of pot sheet inside absorbs flame heat regulating is radiation heat transfer, but the required air capacity of this water bag ignition system flame combustion is often not enough owing to supplementing, cause the flame imperfect combustion, and the bottom of hollow cavity is horizontal tube, the gas produced because being heated in pipe is difficult for discharging, reduced radiation heat transfer efficiency, the inside of this pot sheet is provided with the rectangle baffle plate of circular pillar and some irregular arrangement, be used for dispersing water flow, increase heat exchange efficiency, but the rectangle baffle plate of this circular pillar and minority irregular arrangement is not thorough for the flow-disturbing effect of water, the main flow part of water is relatively concentrated and flow process is short, the heat-exchange time of water in the pot sheet is short, two corners form relative dead angle area, make the heat exchange of whole pot sheet inhomogeneous, insufficient, caused the heat exchange efficiency of pot sheet low.
Summary of the invention
According to above technical problem, the utility model provides the shunting moisturizing pot sheet that a kind of heat exchange efficiency is high, comprise a pot sheet body, water inlet pipe, outlet pipe, the side water route, hollow cavity, the heat exchange hydroecium, the top of described pot sheet body is the heat exchange hydroecium, one side is provided with outlet pipe, described heat exchange hydroecium is along pot sheet body to downward-extension, both sides at pot sheet body form the side water route, and be provided with water inlet pipe at the offside of the lower end outlet pipe of pot sheet body, it is characterized in that: also comprise a minute overflow pipe, the water channel dividing plate, spoiler, between the pot sheet hydroecium extending part of described water inlet pipe offside and water inlet pipe, be provided with minute overflow pipe of 0 ~ 15 ° of gradient, the diameter of described minute overflow pipe is less than the thickness of pot sheet, on the sidewall of described pot sheet body, establish the water channel dividing plate, described water channel dividing plate is long rectangular tab, sidewall higher slice at pot sheet body is interspersed, form water channel, the indoor spoiler that is provided with of described heat-exchanging water, described spoiler is that little rectangular tab is protruded, be interspersed.
The beneficial effects of the utility model are: the utility model has increased water channel dividing plate and spoiler on original basis, current can disperse it when mobile, eliminated the heat exchanging corner district, increased heat-transfer surface, extend flow process and the heat-exchange time of water, improved the heat exchange efficiency of pot sheet, the utility model has also increased minute overflow pipe of 0 ~ 15 ° of gradient, increased heat exchange area, overcome the horizontal water pipe of incomplete water bag fire structure bottom because being subjected to thermogenetic gas to be difficult for the defect of discharging, strengthened the cooling effect to pot sheet bottom, improved water circulation, eliminated the current dead angle area, due to the diameter of minute overflow pipe, be slightly less than the thickness of pot sheet, simultaneously this minute overflow pipe and the gap of pot between sheet also become the entrance of burning required air, make flame completing combustion, improved the exchange capability of heat of pot sheet.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
As Fig. 1, pot sheet body-1, water inlet pipe-2, outlet pipe-3, side water route-4, hollow cavity-5, heat exchange hydroecium-6, minute overflow pipe-7, water channel dividing plate-8, spoiler-9;
The specific embodiment
In conjunction with shown in Figure 1, the utility model is further described:
Embodiment 1
The utility model comprises a pot sheet body 1, water inlet pipe 2, outlet pipe 3, side water route 4, hollow cavity 5, heat exchange hydroecium 6, divide overflow pipe 7, water channel dividing plate 8, spoiler 9, the top of pot sheet body 1 is heat exchange hydroecium 6, one side is provided with outlet pipe 3, heat exchange hydroecium 6 is along pot sheet body 1 to downward-extension, both sides at pot sheet body form side water route 4, and be provided with water inlet pipe 2 at the offside of the lower end outlet pipe 3 of pot sheet body 1, what between pot sheet hydroecium 6 extending parts and the water inlet pipe 2 of water inlet pipe 2 offsides, be provided with one 0 ~ 15 ° of gradients divides overflow pipe 7, its diameter is less than pot thickness of sheet body 1, on the sidewall of pot sheet body 1, be provided with water channel dividing plate 8, sidewall higher slice at pot sheet body is interspersed, in the indoor inclination of heat-exchanging water, be staggeredly distributed with spoiler 9.
Embodiment 2
The He Ce water route, bottom 4 of heat exchange hydroecium 6, a minute overflow pipe 7 surround a hollow cavity 5, flame is in these hollow cavity 5 internal combustion, form a radiant box will, WATER AS FLOW MEDIUM enters a pot sheet body 1 from water inlet pipe 2, the side of flowing through water route 4 and minute overflow pipe 7, enter heat exchange hydroecium 6, current are subjected to the effect of spoiler 9 to be forced to disperse, and the water channel formed along water channel dividing plate 8 flows, and current are full of whole pot sheet body 1 as much as possible, then from outlet pipe 3, flow out, complete whole heat transfer process.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
