Abstract

The utility model relates to a heat collecting stove basin with adjustable flue, which belongs to improved components of various domestic coal stoves. The utility model is characterized in that an adjustable flue heat collecting jacket is added in the stove basin; an annular flue forms between the heat collecting jacket and the shell of the stove basin; the distance between the smoke exhaust on the side face of the wall of the heat collecting jacket and the smoke exhaust open gate of the stove basin can be lengthened or shortened in the annular flue by level and rotary regulation in the shell of the stove basin. The utility model changes the original mode that the stove basin and a fire hole are directly communicated to a chimney nozzle to directly exhaust smoke. The high temperature air produced in the fire hole flows across the smoke exhaust of the heat collecting jacket and flows into the annular flue and forms heat convection in the annular flue, which enables the stove basin to conduct more heat to be used to exchange heat and enhances the service performance and energy-saving effect of the stove.

Description

Adjustable flue thermal-arrest stove basin

The utility model is the improvement parts that are used for various residential coal combustion stoves.

At present, widely used residential coal combustion stove, the elevated temperature heat of stove eye mouth is directly discharged fume with the stove basin and is formed thermal convection current between the open gate, heat energy in the stove eye is not fully used just enters chimney, so the thermal efficiency is low.

The purpose of this utility model provides a kind of can make fire door high temperature the time, forms the conduction of high temperature advection heat for stove basin or the heat exchange of hot-water heating water jacket in the stove basin.When the fire door furnace temperature is low, can make the fume centralized in the stove eye directly enter chimney again, increase the cross-ventilation in the stove eye, furnace temperature is raise fast, improve the energy-saving stove parts of residential coal combustion stove performance.

Realize that the utility model is to have increased accent flue thermal-arrest cover in the stove basin.Transfer the internal diameter of flue thermal-arrest cover identical with fire door or greater than fire door, so that stoking has exhaust opening in the side of jacket wall, eaves is arranged above the jacket wall, the hole slot of Gong stirring is arranged above the eaves, be assemblied in the stove basin shell, between jacket wall external diameter and the stove basin shell internal diameter, constitute the horizontal annular flue, the thermal-arrest cover can horizontally rotate through stirring, and makes the exhaust opening on the jacket wall side, when furnace temperature is high, forward to from stove basin smoke evacuation open gate position far away, make to form high temperature convection current conduction in the annular flue, for stove basin or the heat exchange of hot-water heating water jacket.When furnace temperature is low, forward to from the near position of stove basin smoke evacuation open gate, make the fume centralized in the stove eye directly enter chimney, increase the cross-ventilation in the stove eye, improve furnace temperature fast.

Owing to adopt such scheme, realized that the heat energy of coal furnace makes full use of and the quick furnace temperature that improves, increase in the stove basin and transfer the flue thermal-arrest cover just to become adjustable flue thermal-arrest stove basin, easy to use simple in structure.

Below in conjunction with Fu Tu and embodiment the utility model is further specified.

Fig. 1 is the facade sectional structure chart of adjustable first embodiment of flue thermal-arrest stove basin.

Fig. 2 is the plan cross-section structure chart of second embodiment of adjustable flue thermal-arrest stove basin.

Fig. 3 is the plan cross-section structure chart of the 3rd embodiment of adjustable flue thermal-arrest stove basin.

1. stove basin shells 2. are transferred flue thermal-arrests to overlap 3. stove basins to cover the hole slot that 4. thermal-arrests cover exhaust opening, 5. annular flue 6. stove basins smoke evacuation open gates 7. Gong are stirred among the figure.

In the embodiment shown in fig. 1, transfer flue thermal-arrest cover (2) to be assemblied in the stove basin shell (1), transferring the Nei Yuan hole and the stove eye of flue thermal-arrest cover (2) is concentric, constitute with dark annular flues (5) such as stove basin shells between outer garden of jacket wall and the stove basin shell inwall garden, there is thermal-arrest cover exhaust opening (4) the jacket wall side of thermal-arrest cover (2), the hole slot of Gong stirring (7) is arranged on the eaves above the jacket wall, stir hole slot (7) and transfer the flue thermal-arrest cover in stove basin shell (1), to rotate.

In embodiment illustrated in fig. 2, when furnace temperature was high, the thermal-arrest cover exhaust opening (4) of accent flue thermal-arrest jacket wall side was adjusted to and stove basin smoke evacuation open gate (6) distance the longest high position, in open gate (6) one sides of discharging fume back to the stove basin.

In the embodiment shown in fig. 3, when furnace temperature was hanged down, the thermal-arrest cover exhaust opening (4) of accent flue thermal-arrest jacket wall side was adjusted to and the stove basin is discharged fume open gate (6) apart from the shortest position, in open gate (6) one sides of discharging fume over against the stove basin.

Claims

1, adjustable flue thermal-arrest stove basin, be in stove basin shell, to have increased accent flue thermal-arrest cover, it is characterized in that: be assemblied between the accent flue thermal-arrest cover and stove basin shell in the stove basin shell, the looping flue, transfer the flue thermal-arrest cover can in stove basin shell, horizontally rotate conciliation, make the exhaust opening transferred on the flue thermal-arrest jacket wall side distance, in annular flue, increase or shorten to stove basin smoke evacuation open gate.

2, adjustable flue thermal-arrest stove basin according to claim 1 is characterized in that: transfer the jacket wall side of flue thermal-arrest cover that exhaust opening is arranged, eaves is arranged above the jacket wall, the hole slot of Gong stirring is arranged above the eaves, be assemblied in the stove basin shell, can horizontally rotate through stirring.
