Description

Technical Field

[0001] The present invention relates to the technical field related to heating furnaces, and particularly to a feeding device for a biomass combustion heating furnace. Background Art

[0002] Biomass fuel refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, sugarcane bagasse, rice chaff, etc.). It uses agricultural and forestry waste as raw materials, and is made into various shapes (such as blocks, granules, etc.) through processes such as crushing, mixing, extrusion, and drying. It is a new type of clean fuel that can be directly burned. With the promotion of biomass fuel and the corresponding supporting smoke filtration equipment, biomass fuel has been promoted on a large scale. However, in actual application, smoke overflow still occurs. The main reason is that biomass fuel is not resistant to burning and requires continuous addition of granular fuel. As soon as the furnace door is opened, the smoke inside will overflow, causing pollution. Summary of the Invention

[0003] The object of the present invention is to provide a feeding device for a biomass burning heating furnace, which can effectively solve the problems existing in the background technology.

[0004] In order to solve the problems existing in the background technology, it includes a heating furnace body 1, one side of the heating furnace body 1 is provided with an opening 2 for fuel inlet and outlet, and an upward inclined material guide trough 3 is welded and fixed on the opening 2. The material guide trough 3 is a rectangular tubular structure with openings at both ends. A feeding box 4 that can slide with the gap therewith is provided in the material guide trough 3, and a first positioning plate 5 is welded on the bottom of the feeding box 4 at one end of the outer side of the heating furnace body 1. A second positioning plate 6 corresponding to the first positioning plate 5 is provided at the bottom of the material guide trough 3, and an electric push rod 7 is installed between the first positioning plate 5 and the second positioning plate 6. The bottom of the feeding box 4 is provided with a first discharge trough 8, and the bottom of the material guide trough 3 located in the heating furnace body 1 is provided with a second discharge trough 9 corresponding to the first discharge trough 8, and the end of the second discharge trough 9 is welded with a stop plate 10 for preventing the feeding box 4 from exceeding.

[0005] A smoke-proof plate 11 is installed at the end of the first discharge chute 8 close to one end of the first positioning plate 5, and the periphery of the smoke-proof plate 11 can be directly closed against the inner wall of the heating furnace body 1. When the smoke-proof plate 11 is closed, it can slide on the lower bottom surface of the guide chute 3.

[0006] Slide rails 12 are respectively installed on both sides of the feeding box 4, and a guide slide groove 13 that can slide with the slide rails 12 is opened on the inner wall of the guide groove 3.

[0013] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0014] See Figure 1-2The present invention relates to a heating furnace body 1, wherein the fuel tank body 1 is provided with an opening 2 for fuel inlet and outlet, and a guide trough 3 arranged upwardly inclined is welded and fixed on the opening 2. The guide trough 3 is a rectangular tubular structure with openings at both ends. A feed box 4 that can slide with the gap therein is provided in the guide trough 3. The feed box 4 is located at the bottom of one end of the outer side of the heating furnace body 1 and is welded with a first positioning plate 5. The bottom of the guide trough 3 is provided with a second positioning plate 6 corresponding to the first positioning plate 5. An electric push rod 7 is installed between the first positioning plate 5 and the second positioning plate 6. The bottom of the feed box 4 is provided with a first discharge trough 8. The guide trough 3 is located at the bottom of the heating furnace body 1 and is provided with a second discharge trough 9 corresponding to the first discharge trough 8. The end of the second discharge trough 9 is welded with a stop plate 10 for preventing the feed box 4 from going out.

[0015] A smoke-proof plate 11 is installed at the end of the first discharge chute 8 close to one end of the first positioning plate 5, and the periphery of the smoke-proof plate 11 can be directly closed against the inner wall of the heating furnace body 1. When the smoke-proof plate 11 is closed, it can slide on the lower bottom surface of the guide chute 3.

[0016] Slide rails 12 are respectively installed on both sides of the feeding box 4, and a guide slide groove 13 that can slide with the slide rails 12 is opened on the inner wall of the guide groove 3.

[0017] The feed box 4 is located on the upper top surface near one end of the first positioning plate 5 and is welded and fixed with a stop plate 14 that can slide on the upper top surface of the guide trough 3. When the end of the feed box 4 near one end of the stop plate 10 completely passes over the edge of the second discharge trough 9, the end of the guide trough 3 is out of contact with the stop plate 14.

[0018] The guide trough 3 is provided with a smoke drainage pipe 15 connected to the interior thereof, and the upper end of the smoke drainage pipe 15 is directly connected to the main smoke pipe.

[0019] The following further describes the method and principle of using the technical solution in this specific embodiment with reference to the accompanying drawings:

[0020] When in use, the electric push rod 7 is started to drive the feeding box 4 to move. During the movement of the feeding box 4, the end of the smoke proof plate 11 contacts the end of the second discharge chute 9, so that the feeding box 4 drives the smoke proof plate 11 to make a preliminary closing action during the movement. Since the flow-stop plate 14 is still attached to the upper top surface of the guide chute 3 at this time, the smoke remaining in the feeding box 4 after the smoke proof plate 11 is closed is discharged into the main smoke duct through the smoke guide pipe 15. After the preliminary closure, the smoke proof plate 11 and the bottom plate of the feeding box 4 are attached to the upper surface of the guide chute 3. The bottom surface moves, and when the end of the feed box 4 close to the stop plate 10 completely passes over the edge of the second discharge chute 9, the upper top surface of the end of the guide chute 3 is separated from the contact with the stop plate 14, eliminating the phenomenon of flue gas overflow caused by convection between the inside and outside of the furnace, until the feed box 4 is in a completely open state, and at this time the tail of the feed box 4 also directly passes over the second discharge chute 9, making the entire guide chute 3 in a completely closed state, and then it can be achieved that the phenomenon of flue gas overflow is completely eliminated during the addition of biomass fuel.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
