As shown in fig. 2-4, a rocket furnace ash removal barrel is positioned in a feeding port 400 of a rocket furnace and can slide along the feeding port 400 in a reciprocating manner, and comprises a cylindrical barrel body 100 and fire-isolating sheets 200;

the outer wall of the barrel body 100 is tightly attached to the inner wall of the feed inlet 400, and the barrel body 100 is used for containing ash;

the two sides of the fire-isolating sheet 200 are tightly attached to the inner wall of the feed inlet 400, and the fire-isolating sheet 200 is fixedly connected with the barrel body 100 and is vertical to the bottom of the barrel body 100;

the fire-proof sheet 200 is provided with a welding part 201, the welding part 201 is positioned in the barrel body 100, the welding part 201 is tightly attached to the inner wall and the bottom of the barrel body 100, and the fire-proof sheet 200 is used for cutting the feed inlet 400. The contact is fixed by welding.

The working principle of the rocket furnace is as follows: the wood or particle burning preheating furnace has the advantages that wood or particle burning is firstly used for ignition, the wood or particle burning preheating furnace is firstly started, the temperature of the furnace is not high, flame is small, burning is insufficient, along with the increasing of the temperature of the furnace, vacuum is generated after burning, air is fed from the feeding hole 400, flame is continuously raised and continuously circulated, the effect of sufficient burning is finally achieved, meanwhile, fuel in the furnace is slowly consumed, the fuel in the feeding hole 400 continuously slides down under the action of gravity, the circulation is carried out, enough fuel can be kept in the furnace body, continuous automatic feeding is achieved, and burning is enabled to be more sufficient through keeping the burning temperature. If the feed inlet 400 is too large, the flow rate of air supplemented from the feed inlet 400 is too slow, which makes it difficult to form air flow in the rocket furnace, the combustion of fuel in the furnace chamber is insufficient, which may generate smoke, and on the premise that the flow rate of air at the feed inlet 400 is too slow, the smoke and the burning flames easily flow back to the feed inlet 400. The whole ash removal barrel of the rocket furnace is sunk to the bottom end of the feed port 400, the feed port 400 is divided by the fire isolating sheet 200, so that the feed port 400 is reduced, when fuel is combusted in a hearth of the rocket furnace to generate negative pressure, the air flow of the feed port 400 is unchanged, the area of the feed port 400 is reduced, the flow speed is increased, the air circulation of the hearth is promoted, the combustion efficiency of the fuel is improved, and the smoke is reduced; and because the air flow rate of the feed inlet 400 is accelerated, air passes through the feed inlet 400 to the hearth, so that flame and smoke can be effectively prevented from flowing back from the feed inlet 400; and the ash after the fuel is burnt is piled up in the barrel body 100, and the ash cleaning barrel is integrally lifted out from the feeding hole 400, so that the ash cleaning work is finished, the structure is simple and reliable, the production is convenient, and the cost is low.

In this embodiment, the fire barrier 200 is disposed eccentrically. By changing the dividing proportion of the fire-isolating sheet 200 and eccentrically arranging the fire-isolating sheet 200, two sizes of the feed inlets 400 can be formed, and the ash removal barrel of the rocket furnace is rotated to adapt to the combustion characteristics of different fuels.

In another embodiment, the fire barrier 200 passes through the center of the barrel 100. The front and the back are not separated, and the use effect of the two sides of the fire-proof sheet 200 is the same.

In this embodiment, the top end of the fire-proof piece 200 is provided with a handle positioning rod 300 convenient for lifting. The ash removing barrel of the rocket furnace is convenient to be lifted out of the feeding hole 400, the structure is simple and reliable, the production is convenient, and the cost is low.

In other embodiments, the top end of the fire barrier 200 is hinged with a handle for easy lifting. Handle locating lever 300 is compared to the articulated handle, and it is more convenient to use, and it is more laborsaving to propose this rocket stove deashing bucket from feed inlet 400, but installation cost etc. also can corresponding improvement.

In this embodiment, the barrel 100 and the fire barrier 200 are made of stainless steel.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
