[0002] With the continuous development of the economy, the market demand for activated carbon is constantly increasing, and a large amount of activated carbon is produced, mainly used in metallurgy, filtration and other fields. The carbonization furnace is the key equipment for activated carbon production, which can dry distill and anaerobic carbonize carbon-containing woody materials such as sawdust, rice husks, peanut shells, plant straw, and bark.

[0003] In the production process of activated carbon, various raw materials are first pretreated, and then carbonized and activated. Currently, when the carbonization furnace is in use, some of the pretreated raw materials have been stored for a long time and have high humidity. Some of the materials are clumps, which can easily clog the feed inlet when they are added to the carbonization furnace, resulting in a decrease in the working efficiency of the carbonization furnace. Utility Model Content

[0004] The purpose of this application is to provide a feeding device for a biomass carbonization furnace, in order to solve the problem that when the pre-treated raw materials are stored for a long time and have high moisture content, some of the materials will be clump together and become blocked at the feed inlet when they are added to the carbonization furnace, which leads to a decrease in the working efficiency of the carbonization furnace.

[0005] To solve the above-mentioned technical problems, this application provides a feeding device for a biomass carbonization furnace, including a feeding cylinder, a feeding hopper provided above the feeding cylinder via a connecting box, a dispersing component provided at the connection between the feeding hopper and the connecting box, the connecting box being connected to the top side of the feeding cylinder, a conveying motor fixedly provided on the side wall of the feeding cylinder, a conveying auger connected to the output end of the conveying motor, one end of the conveying auger penetrating the feeding cylinder and rotatably connected to its inner wall, a heating box provided on the side of the feeding cylinder away from the conveying motor, and a drying component provided inside the heating box;

Multiple air delivery short pipes are evenly fixed at the bottom of the hot gas delivery pipe. The other end of the air delivery short pipe is fixedly connected to the top of the feed cylinder.

[0011] It is worth noting that the bottom of the end of the feed cylinder away from the feed hopper is connected to a discharge pipe, and a discharge valve is provided on the discharge pipe.

[0012] Compared with the prior art, the biomass carbonization furnace feeding device provided by this utility model has at least the following beneficial effects:

[0013] 1. A dispersing component is installed in the feed hopper. When the carbonization raw material is added to the feed hopper, the dispersing motor is started.

[0021] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0022] The core of this application is to provide a feeding device for a biomass carbonization furnace, which solves the problem that when the pre-treated raw materials are stored for a long time and have high humidity, some of the materials will be clump together and become blocked at the feed inlet when they are added to the carbonization furnace, resulting in reduced working efficiency of the carbonization furnace.

Figure 2 This is a schematic diagram of the internal structure of a feeding device for a biomass carbonization furnace provided by this utility model. Figure 3 for Figure 2 Enlarged view at point A in the middle. Figure 4 A schematic diagram of a guide plate structure provided by this utility model is shown below. Figures 1 to 4 As stated above.

[0024] A biomass carbonization furnace feeding device includes a feeding cylinder 11, which is cylindrical. The carbonization furnace is located below the discharge end of the feeding cylinder 11. Carbonized material is fed into the carbonization furnace (not shown in the figure) through the feeding cylinder 11. The structure and working principle of the carbonization furnace can be found in the prior art. A feeding hopper 1 is provided above the feeding cylinder 11 via a connecting box 2. The bottom of the feeding hopper 1 is connected to the top of the connecting box 2. An external lifting device feeds the carbonized raw material into the feeding cylinder 11 through the feeding hopper 1 and the connecting box 2. A dispersing component is provided at the connection between the feeding hopper 1 and the connecting box 2. The connecting box 2 is connected to the top side of the feeding cylinder 11. When the external lifting device adds raw material to the feeding hopper 1, the dispersing component disperses the raw material to prevent lumps of material from clogging the feed inlet when added to the carbonization furnace. The feed inlet on one side of the top of the feed cylinder 11 is located directly below the connecting box 2. A conveying motor 10 is fixedly installed on the side wall of the feed cylinder 11. The output end of the conveying motor 10 is connected to a conveying auger 12. One end of the conveying auger 12 passes through the feed cylinder 11 and is rotatably connected to its inner wall. The conveying auger 12 is located inside the feed cylinder 11. The conveying motor 10 provides power to smoothly convey the material added at the feed inlet of the feed cylinder 11 to the discharge outlet. A heating box 13 is installed on the side of the feed cylinder 11 away from the conveying motor 10. A drying component is installed inside the heating box 13. Raw materials that have been stored for a long time are damp and clumped together. After being processed by the dispersing component, they enter the feed cylinder 11 after being added to the feed hopper 1. The conveying motor 10 is started, and the conveying motor 10 drives the conveying auger 12 to rotate, generating axial thrust to push the material in the feed cylinder 11 forward. At the same time, in order to reduce the humidity of the material, the drying component in the heating box 13 is used to dry the material to ensure that the humidity of the material entering the carbonization furnace is moderate and to improve the working efficiency of the carbonization furnace.

[0025] In the above embodiment, the dispersing component includes two connecting rods 3 fixed to the inner wall of the feed hopper 1, and a mounting box 4 fixed between the connecting rods 3. The mounting box 4 is fixed inside the feed hopper 1 by the connecting rods 3. A dispersing motor 5 is installed inside the mounting box 4. The output end of the dispersing motor 5 is connected to a rotating shaft 6. Multiple dispersing rods 7 are evenly arranged on the side wall of the rotating shaft 6. In actual use, the dispersing motor 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the dispersing rods 7 to disperse the material, preventing the agglomerated material from blocking the feed inlet when added to the carbonization furnace, thus improving the feeding efficiency. To further prevent the material from accumulating on the top of the mounting box 4, preferably, the outer top of the mounting box 4 is tapered, so that the material entering the feed hopper 1 slides down the top of the mounting box 4 to the dispersing component and does not accumulate on the top of the mounting box 4.

[0026] Meanwhile, in order to further disperse the material, preferably, a circular dispersion disk 8 is fixedly connected to the bottom end of the rotating shaft 6, and the circular dispersion disk 8 makes the material evenly dispersed.

[0027] To ensure that the material falls quickly into the feed cylinder 11, preferably, a guide plate 9 is fixedly installed on the inner wall of the connecting box 2. The guide plate 9 is located below the dispersing component, and the structure of the guide plate 9 is as follows: Figure 4 As shown, the bottom end of the guide plate 9 is located directly above the feed inlet of the feed cylinder 11, which allows the material to be accurately guided into the feed cylinder 11, thereby increasing the feeding speed.

[0028] In this embodiment, preferably, the drying assembly includes a hot air conveying pipe 16 horizontally arranged at the top of the feed cylinder. One end of the hot air conveying pipe 16 is connected to the top of the heating box 13. A fan 14 is provided through one side of the heating box 13. A heating wire 15 is provided inside the heating box 13. The heating wire 15 has a wide range of applications and is a common drying device. Specifically, the structure and working principle of the heating wire 15 can be found in the prior art. A plurality of air supply short pipes 17 are uniformly fixed at the bottom end of the hot air conveying pipe 16. The other end of the air supply short pipes 17 is fixedly connected to the top of the feed cylinder 11. Hot air is uniformly delivered into the feed cylinder 11 through the air supply short pipes 17, so that the feed cylinder 11 is filled with hot air, thereby drying the material.

[0029] To facilitate material discharge, preferably, a discharge pipe 18 is connected to the bottom of the end of the feed cylinder 11 away from the feed hopper 1. The input end of the discharge pipe 18 is connected to the inside of the feed cylinder 11. A discharge valve 19 is provided on the discharge pipe 18. When adding material to the carbonization furnace, the discharge valve 19 is opened, and the material enters the carbonization furnace along the discharge pipe 18.

[0030] The biomass carbonization furnace feeding device provided in this application operates as follows: Raw materials are added to the feeding hopper 1 via an external lifting device. A dispersing motor 5 drives a rotating shaft 6 to rotate, which in turn drives a dispersing rod 7 to disperse the material. The dispersed material then enters the feeding cylinder 11 along the guide plate 9. A conveying motor 10 drives a conveying auger 12 to rotate, generating axial thrust to propel the material forward within the feeding cylinder 11. Simultaneously, to reduce the material's moisture content, a heating wire 15 and a blower fan 14 are activated. The heating wire 15 begins heating in the heating chamber 13, while the blower fan 14 delivers gas to the feeding cylinder 11 through a hot gas conveying pipe 16 and a short gas supply pipe 17 to dry the material, ensuring appropriate moisture content for the material entering the carbonization furnace and improving the furnace's operating efficiency.
