Energy-efficient heat supply furnace

[0023] The present invention will be further described below in conjunction with the embodiments of the drawings:

[0024] Such as Figure 1 to 6 As shown, a high-efficiency and energy-saving heating furnace includes a furnace body. One end of the top of the furnace body is provided with a stove mouth 1, and the other end is provided with a chimney connection port 2; the lower part of the furnace body is provided with a hearth, and the upper part of the hearth is provided with a hearth 3; It is a hollow closed water tank. It is located on the furnace 3 and below the stove mouth 1, and is provided with a main fire vent 31; on the upper part of the furnace 3, transversely penetrates the peripheral wall of the furnace body, two rows of upper and lower rows of four warm water pipes 4 are arranged in parallel. Each row of warm water pipes 4 is equipped with an ash-sweeping board 5; the lower part of the ash-sweeping board 5 is provided with four semi-circular openings side by side at intervals, and these four openings are stuck on the upper part of the four warm water pipes 4, so that the ash-sweeping board 5 can move radially along the four warm water pipes 4; the middle of the dust sweeping plate 5 is provided with a threaded hole, the end of the tie rod 6 is provided with threads, and the dust sweeping plate 5 is threaded with the tie rod 6; the corresponding position on the peripheral wall of the furnace body is provided Through hole, the pull rod 6 can pull the dust-sweeping plate 5 to reciprocate along the axial direction of the warm water pipe 4 through the through hole; the warm water pipe 4 is arranged in the furnace body, above the furnace 3, near the chimney connection 2, on the furnace 3, located Ten hole-shaped fire outlets 32 are provided under the warm water pipe 4;

[0025] It also includes the fire collecting tube 7, the main fire cover plate 8, and the fire cover plate 9. The fire tube 7 is transparent up and down. It can be buckled at the main fire outlet 31, and its shape is adapted to the shape of the main fire outlet 31: if the main fire outlet If 31 is a square mouth shape, the fire tube 7 is also made into a square mouth shape; and if the main fire outlet 31 is round, the fire tube 7 is also made into a round mouth shape; but the size of the fire tube 7 can be slightly larger than the main fire outlet 31. The height of the fire collecting tube 7 is slightly lower than the top of the furnace body or lower, but it is not higher than the stove mouth 1 of the furnace body in general.

[0026] The main fire cover 8 can cover the main fire outlet 31; the fire cover 9 can cover the hole-shaped fire outlet 32, the fire cover 9 is two pieces, which can respectively cover half of the hole-shaped fire outlet 32; A cleaning port 10 is provided on the peripheral wall of the furnace body at the outlet 31. The furnace body of the present invention is covered with a furnace body shell, and the furnace body shell is a sandwich structure, which is the furnace water tank; the hollow closed water tank between the furnace water tank and the furnace, the flue water tank in the chimney, the series core water tank, etc. , Can be connected to each other or one to one, you can choose any.

[0027] The working principle and working process of the present invention are as follows:

[0028] Such as Figure 1 to 6 As shown, when the present invention is used, the furnace water tank, the furnace water tank, the hollow closed water tank of the furnace, the flue water tank in the chimney, the core water tank, etc., can be carried out according to their respective outlet water pipe connections according to their needs. Mutual or one-to-one communication. When cooking and boiling water, you can cover all the hole-shaped fire outlets 32 with two fire cover plates 9; of course, you can also cover a fire cover plate 9 or not cover the fire plate 9, which depends on the main fire outlet 31 The firepower required depends on the size of the fire; at the same time, the fire collecting tube 7 is buckled at the main fire outlet 31, so that almost all the flames flow from the main fire outlet 31 to the stove mouth 1; and during the night sleep time, all firepower is required for centralized heating. Therefore, the main fire cover 8 can cover the main fire outlet 31, and the fire cover 9 provided with the fire cover 9 can be removed, so that almost all the flames of the present invention are ejected from the hole-shaped fire outlet 32, burned through the warm water pipe 4, and then lead to Chimney; the warm water pipe 4 set up in this way can pass almost all the fire leading to the external chimney to absorb heat, and the external pipe bypasses any part of the room for heating and sleeping; after the present invention has been used for a long time, the warm water pipe 4 There is a lot of coal ash accumulated on it, which will affect its heat absorption capacity. At this time, the pull rod 6 should be used to pull the dust sweeping plate 5 to reciprocate along the axial direction of the warm water pipe 4 through the through holes opened in the corresponding position on the peripheral wall of the furnace body, so that all the dust on the warm water pipe 4 can be cleaned. Sweeping and restoring the heat absorption capacity of the warm water pipe 4 greatly improves the efficiency of the warm water pipe to absorb heat. The dust swept from the warm water pipe 4 can be taken out through the dust removal port 10; the main fire cover 8 and the fire cover 9 can be installed and drawn out through the dust removal port 10; fire collection tube 7, main The loading and unloading of the fire cover 8 can be performed through the stove port 1.
