Description

A kind of shunting moisturizing pot sheet

?

Technical field

The present invention relates to cast-iron boiler sheet, relate 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 bottom of the pot sheet of traditional cast-iron boiler adopts ring-shaped water jacket structure, in the hollow cavity that flame surrounds at ring-shaped water jacket, burn, form 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 flame imperfect combustion, and the bottom of hollow cavity is horizontal tube, the gas producing because being heated in pipe is difficult for discharging, reduce 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 pot sheet is short, two corners form relative dead angle area, make the heat exchange of whole pot sheet inhomogeneous, insufficient, cause the heat exchange efficiency of pot sheet low.

Summary of the invention

According to above technical problem, the invention 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, side water route, hollow cavity, heat exchange hydroecium, the top of described pot sheet body is 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 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 point overflow pipe, 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 point overflow pipe of 0 ~ 15 ° of gradient, the diameter of described point of overflow pipe is less than the thickness of pot sheet, on the sidewall of described pot sheet body, establish 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.

Beneficial effect of the present invention is: the present invention has increased water channel dividing plate and spoiler on original basis, current can disperse it when mobile, eliminate heat exchanging corner district, increase heat-transfer surface, extend flow process and the heat-exchange time of water, improve the heat exchange efficiency of pot sheet, the present invention has also increased point overflow pipe of 0 ~ 15 ° of gradient, increase heat exchange area, overcome the horizontal water pipe of incomplete water bag fire structure bottom because being subject to thermogenetic gas to be difficult for the defect of discharging, strengthen the cooling effect to pot sheet bottom, improve water circulation, eliminate current dead angle area, owing to dividing the diameter of overflow pipe to be slightly less than the thickness of pot sheet, gap between this point of overflow pipe and pot sheet also becomes the entrance of burning required air simultaneously, make flame completing combustion, improve the exchange capability of heat of pot sheet.

Brief description of the drawings

Fig. 1 is structural representation of the present invention.

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, point overflow pipe-7, water channel dividing plate-8, spoiler-9;

Detailed description of the invention

Shown in Fig. 1, the present invention is further described:

Embodiment 1

The present invention includes 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 a pot thickness for 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, be staggeredly distributed with spoiler 9 in the indoor inclination of heat-exchanging water.

Embodiment 2

He Ce water route, bottom 4, point overflow pipe 7 of heat exchange hydroecium 6 surround a hollow cavity 5, flame is in the interior burning of this hollow cavity 5, 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 point overflow pipe 7, enter heat exchange hydroecium 6, current are subject to the effect of spoiler 9 by Forced Dispersion, and the water channel forming along water channel dividing plate 8 flows, and current are full of whole pot sheet body 1 as much as possible, then flow out from outlet pipe 3, complete whole heat transfer process.

 

The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, and these improve and also should be considered as protection scope of the present invention.
