The utility model directly absorb heat, besides, the utility model is provided with the double-layer heat-insulating layer, so the utility model has high thermal efficiency; the stove body of the utility model can be arbitrarily combined according to needs; the utility model adopts the extinguishing cover which is provided with a gap and a cover skirt, so the fire behavior can be regulated, the extinguishing is convenient, and the extinguishing can be more than ten hours; the utility model has the advantages of simple manufacturing processes and low cost.

Description

Cooking and heating furnace

The utility model belongs to a kind of stove, relates to a kind of cooking and heating furnace.

Existing cooking and heating furnace, its flue all adopt founding technology to be formed by iron casting, and the stove of this form can be divided into two kinds substantially, and a kind of its flue is not with water jacket, another kind of its flue band cyclic water jacket.Flue with the cast iron stove of water jacket, does not have the dentation sheet on its flue, can effectively improve the performance that absorbs heat like this, but because the heat of this stove is the secondary conduction, and heat waste is big, owing to bank up a fire under adopting, furnace bottom, stove end opening are all damaged easily simultaneously; The cast iron stove of flue band water jacket, its flue is provided with endless loop can pass through recirculated water, and this stove can effectively solve the loss problem of heat, but the mode of banking up a fire of this stove bothers, need constantly to adjust the openings of sizes of fire-sealing ring, otherwise be not that fire extinguishing is exactly excessive very hot oven.Because the endless loop on the flue is made by founding technology, if stay sand grains, the utmost point is easy-clear not in the circle, can cause flue to stop up so in addition, influence the circulation of water.Run into this situation, both just stove fire was prosperous again, and the water in the steam heating pipe also is cold.In addition, above-mentioned two kinds of stoves all adopt the infundibulate fire-suppressing cover, because infundibulate inclined-plane and burner distance, space are big, must distribute a part of heat under fire-suppressing cover, thereby influence whole conduction of heat.

The purpose of this utility model provides a kind of cooking and heating furnace, and it has reduced the loss of heat, and is energy-conservation, and the form of banking up a fire on adopting easily.

The purpose of this utility model realizes by following scheme: cooking and heating furnace is made up of stove skin, stove internal layer, fire grate, ash bucket, fire-suppressing cover, fire sealing cover etc., and the stove skin is the crust of stove, and the stove internal layer then comprises: flue, tile, pallet and heat-insulation layer.The inboard top of described flue is dentation, be cavity, the flue both sides are fixed with hangers, have ring flange on the hangers, leave intake-outlet on the ring flange, this intake-outlet is connected with the cavity tooth of flue, and the outer rim of circular fire-suppressing cover has the gap of equidistant arrangement, lid is cast with the lid skirt of downward extension down, is filled with refractory cement in the lid skirt.

The flue of this cooking and heating furnace is an inner tooth type, and the sectional area of flue is increased, because internal tooth is cavity and can leads to recirculated water, therefore directly absorbs heat simultaneously, and thermal losses is little.Body of heater adopts double-layer heat insulation in addition, and the thermal efficiency is significantly improved, and the fire door temperature can reach about 700 ℃.Because the body of heater both sides are fixed with ring flange, can make body of heater connect combination arbitrarily as required; The fire-suppressing cover that has the gap shape can be regulated the intensity of a fire.The mode of banking up a fire in the employing, it is simple to bank up a fire, and fire-sealing time is long.This in addition stove technology is simple, and cost is low.

Fig. 1 is a generalized section of the present utility model

Fig. 2 is the schematic top plan view of fire-suppressing cover in the utility model

Fig. 3 is the generalized section of fire-suppressing cover in the utility model

Be described as follows below in conjunction with drawings and Examples:

In Fig. 1,2, cooking and heating furnace is made up of stove skin 1, stove internal layer 2, fire grate 3, ash bucket 4, fire-suppressing cover 5, fire sealing cover etc.Stove skin 1 is the crust of stove.Stove internal layer 2 comprises: flue 6, tile 7, pallet 8, adiabator layer 9.The inboard top of described flue 6 is dentation, be cavity.If based on heating, the length of internal tooth accounts for more than 1/4th of flue total length; If based on cooking, the length of internal tooth accounts for below 1/4th of flue total length.The two ends, the outside of flue 6 are installed with hangers 10, and ring flange 11 is housed on the hangers 10.Can connect other body of heater as required arbitrarily again in the body of heater both sides like this.It is microscler that ring flange is, and has the intake-

outlet

12,13 that is connected with internal tooth on it.The internal layer of flue 6 is put tile 7.Be filled with aluminium silicate wool heat-insulation layer 9 in the interlayer between flue and tile, and outer 1 of flue 6 and stove also are filled with rock wool heat-preservation material layer 9.Fire grate 3, pallet 8 and ash bucket 4 are equipped with in the lower end of stove internal layer 2.

By Fig. 2 and Fig. 3 as can be known: described fire-suppressing cover 5 is formed by iron casting, and is rounded.The center is cast with drop handle 14, and the lid lower end is cast with covers skirt 15.Be cast on the fire-suppressing cover cover skirt after, significantly reduced the distance between fire-suppressing cover and burner, heat almost all is fed in the flue along lid skirt dual-side gap, recirculated water is heated rapidly.Being filled with refractory cement 16 in the lid skirt makes fire-suppressing cover high temperature resistant.There is the gap 17 of equidistant arrangement at the lid edge.Distance between two gap equates with two interdental spaces on the flue.If fire-suppressing cover 5 is covered on the flue of stove internal layer, regulate the interior between cog space on gap 17 and the flue 6, the heat and the intensity of a fire that can regulate stove, and can be with accent is fiery, banking up a fire is combined as a whole.This mode of banking up a fire, fire-sealing time is long, and easy.

Above-mentioned gap 17 also can be designed to tubaeformly tiltedly slit, profile of tooth is slitted, arcuation slits etc.

During use, feed recirculated water earlier, and light stove fire according to a conventional method.During heating fire-suppressing cover 5 is covered on flue 6, the gap on the adjusting fire-suppressing cover and the interior interdental space of flue can make a little less than hyperactivity of fire or the fire.When banking up a fire, earlier fire sealing cover is covered, compress fire-suppressing cover, and interdental space in gap on it and the flue is transferred to minimum getting final product.
