CN2449096Y - Tooth type air-return energy-saving stove core for heating - Google Patents

Abstract

The utility model discloses a tooth type air-return energy-saving stove core for heating. Convex teeth are uniformly distributed on the inner wall of the stove core, the upper part of the stove core is provided with a cover ring seat with a cover, a heat-insulating layer is sheathed on the stove core, and concave holes are densely distributed on the surface of the heat-insulating layer. An air passage is easily formed in the stove core because of the action of the convex teeth, and the combustion of the coal is benefited. Most of the water in the smoke gas in a stove can be adsorbed on the concave holes and be dried out. Therefore, the water dropping phenomenon is hardly generated. Compared with the existing stove core, the utility model has the advantages of sufficient combustion, coal saving, energy saving, easy control of the fire power, and hard generation of the water dropping phenomenon.

Description

Tooth-like return air heating energy conserving combustion chamber

The utility model relates to a kind of tooth-like return air heating energy conserving combustion chamber that is used on the coal-fired air return stove.

At present, the combustion chamber that uses in existing air return stove adopts the circular cone core structure mostly, though the combustion chamber of this circular cone core structure has advantage of simple structure, but shortcoming such as exist but that burning of coal is incomplete in the rapid heat dissipation, combustion chamber, coal consumption is high, firepower is wayward, the stove dripping phenomenon is serious when lighting a fire burning, therefore existing combustion chamber is still not ideal enough in use.

The purpose of this utility model is: provide a kind of sufficient combustion, firepower to control, be not prone to the tooth-like return air heating energy conserving combustion chamber that drips easily.

The utility model is to constitute like this: it comprises combustion chamber (1), on the inwall of combustion chamber (1), be evenly distributed with double wedge (2), the decorative cover seat (3) that has lid is housed on the top of combustion chamber (1), on combustion chamber (1), also be with heat-insulation layer (4), on the surface of heat-insulation layer (4), be densely covered with shrinkage pool (5); Have lid on the decorative cover seat (3) of lid and cover (6) by two semicircles and form, and each semicircle lid (6) all is connected with decorative cover seat (3) by a bearing pin (7) respectively, cover on (6) at semicircle and also connect by drawing handle (8).

Owing to adopted technique scheme, when coal burns in combustion chamber (1), owing on the inwall of combustion chamber (1), be evenly distributed with double wedge (2), therefore the coal in the combustion chamber (1) is not easy combustion chamber is filled up, effect owing to double wedge (2) in the combustion chamber (1) forms airway easily, under the condition of oxygen supply abundance, coal just can burn fully like this; Can control the switching of semicircle lid (6) by drawing handle (8), thereby control the firepower size easily; The suction-operated of shrinkage pool (5) owing to gather on heat-insulation layer (4) surface, the most of moisture in the inner flue gas of the stove all is attracted on the shrinkage pool (5) and is dryouied, and therefore is not easy to occur dripping phenomenon.So the utility model is compared with existing combustion chamber and is had sufficient combustion, economizes that coal is energy-conservation, firepower is controlled easily, be not prone to the advantage of dripping.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the A-A cross-sectional schematic of accompanying drawing 1;

Structural representation when accompanying drawing 3 is gone up use for the utility model is installed in air return stove (9).

Embodiment of the present utility model: the material of combustion chamber (1) can adopt existing combustion chamber material to make, during making, on the inwall of combustion chamber (1), produce double wedge (2) simultaneously by even distribution, and load onto the decorative cover seat (3) that has lid on the top of combustion chamber (1), and on combustion chamber (1), put heat-insulation layer (4) again, also heat-insulation layer (4) and combustion chamber (1) can be made as one, heat-insulation layer (4) is not all covered in combustion chamber (1) during making, preferably keep one section a of combustion chamber (1), help the heat release heating like this, on the surface of heat-insulation layer (4), produce densely covered shrinkage pool (5) simultaneously, to have lid on the decorative cover seat (3) of lid is made into by two semicircles lids (6) and forms, and all use a bearing pin (7) to be connected respectively on each semicircle lid (6), cover at semicircle and reconnect drawing handle on (6) and (8) with decorative cover seat (3).

Claims (2)

1, a kind of tooth-like return air heating energy conserving combustion chamber, it comprises combustion chamber (1), it is characterized in that: on the inwall of combustion chamber (1), be evenly distributed with double wedge (2), the decorative cover seat (3) that has lid is housed on the top of combustion chamber (1), on combustion chamber (1), also be with heat-insulation layer (4), on the surface of heat-insulation layer (4), be densely covered with shrinkage pool (5).

2, tooth-like return air heating energy conserving combustion chamber according to claim 1, it is characterized in that: have lid on the decorative cover seat (3) of lid and cover (6) by two semicircles and form, and each semicircle lid (6) all is connected with decorative cover seat (3) by a bearing pin (7) respectively, also connects by drawing handle (8) on semicircle lid (6).
