Description

Technical Field

[0001] The utility model relates to the field of straw processing, in particular to a straw carbonization processing device. Background Art

[0002] Through carbonization treatment, straw can be converted into valuable products such as biochar, which is widely used in soil improvement, energy utilization and other fields, helping to promote the development of agricultural circular economy.

[0003] Due to the unreasonable furnace structure design of some existing devices, the straw is heated unevenly during the carbonization process. The temperature in some areas is too high, causing excessive burning of the straw or even ash formation, while the temperature in some areas is insufficient, resulting in incomplete carbonization of the straw, forming a "half-cooked" phenomenon, which seriously affects the carbonization efficiency and product quality.

[0004] Some devices can only process specific straw types or moisture contents, lacking adaptability to different types and conditions of straw, limiting their application. During the carbonization process, process parameters such as temperature and time must be adjusted based on factors such as straw type and moisture content. However, some existing devices have difficulty adjusting these parameters, making it difficult to meet diverse processing needs. Utility Model Content

[0005] In order to make up for the deficiencies of the existing technical problems, the purpose of the utility model is to provide a straw carbonization treatment device, which solves the following technical problems: how to improve the efficiency of straw carbonization treatment and how to ensure that the straw is evenly heated during the carbonization process.

[0006] In order to solve the problems of the prior art, the technical solutions of the present utility model are as follows:

[0007] A straw carbonization processing device includes a furnace box, the upper part of the furnace box is conical, a smoke exhaust pipe is connected to the center of the top of the furnace box, the conical part of the furnace box extends downward to form a cylindrical inner cavity, the bottom of the furnace box is in an inverted cone shape, a discharge pipe is connected to the center of the bottom of the furnace box, an interlayer shell is fixedly connected to the inside of the discharge pipe, a baffle is slidably inserted in the interlayer shell, a filling pipe is connected to one side of the top of the furnace box, and a sealing cover is installed on the top of the filling pipe.

[0008] Preferably, a vibration motor is installed on one side of the furnace box. Starting the vibration motor can generate vibration, which loosens the carbonized material and flows smoothly along the bottom of the furnace box to the discharge pipe, thereby accelerating the discharge speed and improving the collection efficiency.

[0009] Preferably, a vent pipe is provided on one side of the furnace box, and a sealing plug is provided at one end of the vent pipe. In the early stage of carbonization, an appropriate amount of air is introduced into the furnace box through the vent pipe to support the combustion and carbonization reaction of the straw. As the carbonization process deepens, the sealing plug can be gradually closed or adjusted to reduce the air circulation and promote incomplete combustion and carbonization of the straw.

[0010] Preferably, a fixing ring is fixedly connected to the outside of the furnace box, and a support frame is fixedly connected to the bottom of the fixing ring. The two components together constitute a stable support structure of the furnace box, ensuring the stability and safety of the entire processing device.

[0011] Preferably, the four corners of the bottom of the support frame are fixedly connected with a bottom plate, and the bottom plate increases the contact area between the support frame and the ground, thereby improving the stability of the entire processing device.

[0012] Preferably, a detection window is provided on one side of the furnace box, through which the operator can intuitively understand the burning state of the straw, the degree of carbonization, and parameters such as the temperature and smoke in the furnace box.

[0013] Preferably, a material collecting bucket is provided below the furnace box for collecting the carbonized material discharged from the discharge pipe.

[0014] Compared with the prior art, the advantages of the present invention are as follows:

[0015] 1. The utility model adopts a unique furnace box design, especially the conical structure at the top and the inverted conical discharge port at the bottom, so that the straw fragments can be evenly stacked in the furnace box and incompletely burned from top to bottom, thereby achieving efficient carbonization treatment. This treatment method not only improves the carbonization efficiency of straw, but also ensures the quality of the carbonized product.

[0016] 2. The device is designed with components such as a filling pipe, a discharge pipe, and a detection window, so that the operator can easily feed the straw, collect the carbonized material, and observe the inside of the furnace box. In particular, the application of the vibration motor enables the carbonized straw material to be discharged more smoothly, reducing the difficulty of manual cleaning.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] The straw carbonization treatment device comprises a furnace box 1;

[0023] like Figures 1 to 3 As shown, the upper part of the furnace box 1 is conical, and a smoke exhaust pipe 2 is connected to the center of the top of the furnace box 1. The conical part of the furnace box 1 extends downward to form a cylindrical inner cavity. The bottom of the furnace box 1 is inverted conical, and a discharge pipe 3 is connected to the center of the bottom of the furnace box 1. The discharge pipe 3 is fixedly connected to an interlayer shell 4 inside, and a baffle 5 is slidably inserted in the interlayer shell 4. A stuffing pipe 6 is connected to one side of the top of the furnace box 1, and a sealing cover 7 is installed on the top of the stuffing pipe 6.

[0024] The upper conical furnace box 1 is narrow at the top and wide at the bottom, which not only facilitates the centralized stacking of straw chips, but also optimizes the heat transfer efficiency during the combustion process. The smoke exhaust pipe 2 is used to discharge the smoke and harmful gases generated during the carbonization process. The furnace box 1 is connected to a filling pipe 6, which remains open during feeding, allowing straw chips to be directly fed into the furnace box 1 from the top. After the straw chips enter the furnace box 1 through the filling pipe 6, they naturally accumulate into an inverted cone shape, preparing for the subsequent carbonization process.

[0025] When the furnace box 1 is filled with straw chips, the sealing cover 7 of the filling pipe 6 is closed to ensure the sealing of the furnace box 1. Then, the top of the straw chips is ignited from the opening of the filling pipe 6. Due to the cone-shaped design of the upper part of the furnace box 1, the flame will quickly spread upward and ignite the entire straw pile. However, since the straw is incompletely burned from top to bottom in the furnace box 1, this combustion method causes the straw to gradually carbonize rather than completely burn into ash. During this process, the smoke exhaust pipe 2 continuously discharges the generated smoke and exhaust gas to maintain a stable environment in the furnace box 1.

[0026] As the carbonization process proceeds, the straw fragments are gradually transformed into carbonized materials. The inverted cone-shaped design of the bottom of the furnace box 1 allows the carbonized straw materials to flow smoothly to the discharge pipe 3 located at the bottom of the furnace box 1 .

[0027] like Figures 1 to 3 As shown, a vibration motor 8 is installed on one side of the furnace box 1. The vibration motor 8 can be started when needed to promote the rapid discharge of carbonized materials through vibration, thereby improving the collection efficiency.

[0028] like Figures 1 to 3 As shown, a vent pipe 9 is provided on one side of the furnace box 1, and a sealing plug 10 is provided at one end of the vent pipe 9, so that the air flow in the furnace box 1 can be adjusted as needed.

[0029] like Figures 1 to 3As shown, a fixing ring 11 is fixedly connected to the outside of the furnace box 1, and a support frame 12 is fixedly connected to the bottom of the fixing ring 11. The fixing ring 11 enhances the connection strength between the furnace box 1 and the support frame 12 to prevent the furnace box 1 from shaking or tipping over during use. The support frame 12 is responsible for firmly supporting the furnace box 1 and its internal equipment on the ground to ensure the stability and safety of the entire processing device.

[0030] like Figures 1 to 3 As shown, the four corners of the bottom of the support frame 12 are fixedly connected to the bottom plate 13, and the bottom plate 13 increases the contact area between the support frame 12 and the ground, thereby improving the stability of the entire processing device.

[0031] like Figures 1 to 3 As shown, a detection window 14 is provided on one side of the furnace box 1 to facilitate the operator to observe the carbonization condition inside the furnace box 1 and adjust the operating parameters in time.

[0032] like Figures 1 to 3 As shown, a material receiving barrel 15 is provided under the furnace box 1. After carbonization is completed, the baffle 5 in the discharge pipe 3 is opened, and the carbonized material will be automatically discharged into the material receiving barrel 15 under the action of gravity. The design of the material receiving barrel 15 facilitates the centralized collection and storage of carbonized materials, reducing the scattering and waste of carbonized materials.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
