[Name of invention made by ISA according to Rule 37.2] A drying oven

Technical field

The invention relates to a stove device, in particular to a novel oven.

Background technique

In rural areas, it is often necessary to dry crops, wood, bamboo, etc. The general drying furnace has a complicated structure and a high price, which is difficult for farmers to afford. In order to increase the drying temperature, accelerate the fuel burning speed and improve the combustion efficiency, a general drying furnace usually needs to provide a blower at the mouth of the furnace to send the air into the furnace, which undoubtedly increases the cost and consumes the electric energy.

Summary of the invention

The object of the present invention is to overcome the shortcomings and deficiencies in the prior art, and to provide a novel drying furnace capable of improving combustion efficiency by utilizing the principle of air convection.

The invention is achieved by the following scheme: a novel drying furnace comprising a furnace door, a furnace body, a combustion chamber 3, a heat pipe and an exhaust pipe, the furnace body being sealed at one end and the other end being connected to the furnace door, An inclined furnace bridge is arranged in the furnace door, and the furnace bridge divides the furnace door into an upper part feeding inlet and a lower part air inlet, wherein the furnace body is horizontally provided with a fuel board that divides the furnace body into upper and lower parts, the furnace The lower end of the bridge is connected to the fuel plate, and the combustion chamber 3 is vertically mounted on the furnace body opposite to the furnace door, the upper end of which is sealed, and the lower end is in communication with the furnace body; the heat pipe is perpendicular to the combustion chamber 3 and is installed in the combustion chamber 3 The upper portion is in communication with the combustion chamber 3, and the exhaust duct is vertically installed on the heat pipe and communicates with the heat pipe.

Further, the furnace body, the combustion chamber 3, the heat pipe and the exhaust pipe are all cylindrical metal pipes.

Further, the end of the heat pipe is provided with a movable opening and closing slag door having the same shape as the cross section.

Further, the fuel plate is a grid-like fuel plate.

The invention has the advantages of simple and practical design, ingenious design, drying of the object through the heat conduction of the metal tube, and controlling the combustion speed by controlling the air convection speed by opening or closing the furnace door, thereby achieving the purpose of controlling the temperature of the drying furnace. The blower is eliminated, reducing costs.

The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

detailed description

1 and 2, the drying furnace includes a furnace door 1, a furnace body 2, a combustion chamber 3, a heat pipe 4, and an exhaust pipe 5. The furnace body 2, the combustion chamber 3, the heat pipe 4 and the exhaust pipe 5 are all cylindrical metal pipes.

The furnace body 2 is supported by a support member 6 disposed below it. The furnace body 2 is sealed at one end and connected to the furnace door 1 at the other end. An inclined furnace bridge 11 is disposed in the furnace door 1, and the furnace bridge 11 divides the furnace door 1 into an upper portion feed port 12 and a lower portion air inlet port 13. The furnace body 2 is horizontally disposed with a fuel plate 21 dividing the furnace body 2 into upper and lower portions, and the fuel plate 21 is connected to the lower end of the furnace bridge 11, as shown in FIG. .

The combustion chamber 3 is vertically mounted on the furnace body 2 at the opposite end from the furnace door 1, and its upper end is sealed, and the lower end is in communication with the furnace body 2. The heat pipe 4 is perpendicular to the combustion chamber 3 and is installed at the upper portion of the combustion chamber 3, and its front end is in communication with the combustion chamber 3, and the end is provided with a movable opening and closing slag door 41 having the same shape as the cross section. When the drying furnace is used, the lower slag discharge door 41 is closed, and when the ash in the heat pipe 4 needs to be cleaned, the slag discharge door 41 can be opened for cleaning. The exhaust duct 5 is vertically installed at the end of the heat pipe 4, and the bottom thereof is in communication with the heat pipe 4.

The present invention operates in such a manner that the articles to be dried are placed around the drying furnace, and then fuel such as straw, firewood, etc., is placed in the furnace body 2 through the feed port 12, and is ignited in the furnace body 2. At this time, the heat of combustion of the fuel sequentially passes through the furnace body 2, the combustion chamber 3, and the heat pipe 4, and the furnace body 2, the combustion chamber 3, and the heat pipe 4 can be heated. Since the furnace body 2, the combustion chamber 3 and the heat pipe 4 are all metal pipes, the heat conduction speed is fast, and the heat inside thereof is quickly radiated outward, so that the temperature of the surrounding air rises.

The furnace body 2 is supported by the support member 6 so as to have a space below it, so that the heat of the furnace body 2 can be better utilized, and the air convection can be made smoother. The drying furnace of the present invention divides the furnace body 2 into upper and lower parts, and the middle is separated by a grid-like fuel plate 21. The main purpose of this is to utilize the natural convection of the hot gas in the furnace to make the fuel burn more vigorously. When the feed port 12 of the furnace door 1 is opened, the fuel in the furnace body is normally burned, and air can enter from the feed port 12 and the air inlet port 13, and the air convection speed in the drying furnace is slow. When it is necessary to increase the drying temperature to make the fuel burn more vigorously, the feed port 12 can be closed. At this time, as shown by the arrow in Fig. 1, the hot gas in the upper part of the furnace body 2 rises, the pressure is reduced, and the air pressure difference is formed with the lower portion. The air at the air inlet 13 is accelerated into the lower portion of the furnace body 2, and enters the upper portion of the furnace body through the grid of the fuel plate 21, and sufficient air makes the fuel burn more vigorously, thereby achieving the purpose of utilizing natural convection of the air to improve combustion efficiency.

The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are possible without departing from the spirit and scope of the present invention. Intended to include these changes and modifications.
