Abstract

The utility model relates to a novel tea stove which comprises a stove casing, a hearth, smoke and fire channels and water interlayers, wherein the hearth is positioned at the inner lower part of the stove casing; the lower ends of the smoke and fire channels are connected with the upper end of the hearth; the water interlayers are positioned inside the stove casing and among the stove casing, the furnace and the smoke and fire channels; the upper part and the lower part of the stove casing are respectively provided with a water outlet and a water return port; one side of the stove casing, corresponding to the middle part, is provided with a stove port; the top part of the stove casing is provided with a smoke exhaust port; the quantity of the smoke and fire channels is numerous, and the smoke and fire channels are vertically arranged at intervals; the water interlayers are arranged between every two smoke and fire channels; the inside of each water interlayer is provided with one layer of enamel layer in a compounding way. The enamel inside the water interlayers of the utility model is smooth and is capable of delaying scale formation and preventing impurities in stove casing materials from decomposing into water, and the water quality can be ensured. Guide plates in the smoke and fire channels can extend the flowing paths of fire and smoke, which increases the residence time, improves the thermal efficiency and reduces the energy consumption. A venting of the hearth can release the pressure of residual gas which is already detonated, and thus, accidents can be prevented.

Description

A kind of novel tea furnace

Technical field

The utility model relates to a kind of novel tea furnace.

Background technology

The water interlayer inboard generally is the material of body of heater in the existing tea furnace that is used for boiling water, and as steel, iron etc., its shortcoming is easy fouling, influence heat conduction after the fouling, not only cause energy waste, but also cause fouling place body of heater local dry burning, influence the service life of boiler.Impurity in the body of heater can decompose in the water in addition, reduces water quality.In addition, existing is that the flue on the tea furnace top of the energy is the tubular of hollow with coal, combustion gas and fuel oil, pyrotechnics directly from flue by discharging, within it the time that stops short, heat exchange is insufficient, has reduced the thermal efficiency, strengthens fuel consumption.In addition, when igniting,, may cause blast if residual combustion gas is arranged in the burner hearth.

Summary of the invention

The purpose of this utility model just provides a kind of inboard incrustation of water interlayer, good, hot tea furnace of imitating height and preventing to light a fire blast of water quality of delaying.

The technical solution of the utility model is: comprise furnace shell, burner hearth, smoke flue, water interlayer, burner hearth is positioned at the furnace shell bottom, and the smoke flue lower end is connected with the burner hearth upper end, and water interlayer is in the furnace shell inboard and between furnace shell and burner hearth and smoke flue; In described furnace shell top and the bottom delivery port and water return outlet are arranged respectively, furnace shell one side at corresponding burner hearth middle part has fire door, at the furnace shell top exhaust opening is arranged, and described smoke flue has a plurality of and vertical interval to arrange, between each smoke flue water interlayer, all compound one deck enamel layer in the inboard of described water interlayer.

In each smoke flue, be spaced a plurality of splayed guide plates from top to bottom.

Described burner hearth connects an explosion-protection equipment, and it comprises the lid of connecting leg and outer end thereof, and connecting leg is inner to be communicated with burner hearth, on one side lid is hinged with the connecting leg outer end on one side; One observation panel is arranged above described fire door.

The enamel of the utility model water interlayer inboard is smooth to delay fouling, also stops the impurity in the furnace shell material to decompose in the water, has guaranteed water quality.Guide plate in a plurality of flues has increased pyrotechnics circulation distance therein, has increased the time of staying, has improved hot effect, has reduced energy consumption.The venting of burner hearth can discharge the pressure after residual combustible gas is ignited, and tries to avert accidents.

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the right view of Fig. 1.

The specific embodiment

Referring to Fig. 1-Fig. 3, the utility model comprises furnace shell 1, burner hearth 2, smoke flue 3, water interlayer 4, and burner hearth 2 is positioned at furnace shell 1 bottom, and smoke flue 3 has a plurality of and vertical interval to arrange that its distribution form is: the body of heater axle center has one, around this axle center along a plurality of circle distribution.The lower end of each smoke flue 3 is connected with the upper end of burner hearth 2.Water interlayer 4 is in the furnace shell inboard and between furnace shell 1 and burner hearth 2 and smoke flue 3; In the top and the bottom of described furnace shell 1 delivery port 11 and water return outlet 12 are arranged respectively, furnace shell one side at corresponding burner hearth middle part has fire door 13, at the top of furnace shell 1 exhaust opening 14 is arranged, and is spaced a plurality of splayed guide plates 31 in each smoke flue 3 from top to bottom.Also water interlayer 4 between each smoke flue, all compound one deck enamel layer in the inboard of described water interlayer 4.

There is horizontally-arranged pipe 5 to be communicated with the water interlayer of both sides on the top of described burner hearth 2.

One observation panel 17 is arranged above fire door 13.Also temperature-sensing probe 9 and water-level probe 10 can be set on the top of water interlayer 4, be used for carrying out the control of water temperature and water level.

Described burner hearth 2 connects an explosion-protection equipment, and it comprises the lid 72 of connecting leg 71 and outer end thereof, and the inner of connecting leg 71 is communicated with burner hearth 2, on one side lid 72 is hinged with connecting leg 71 outer ends on one side.Lid is inclined upwardly slightly, makes it cover outer end at connecting leg 71 by gravity.If the interior residual combustion gas that has of burner hearth is fired the pressure that is produced at igniting rear cover body 72 by combustion gas and pushes open, the power that will fire discharges, and prevents blast.
