Description

Technical Field

[0001] This utility model relates to the field of charcoal burning, and in particular to the combustion chamber of a carbonization furnace. Background Technology

[0002] Charcoal burning is essentially a process in which wood is thermally decomposed (by distillation or carbonization) in a carbonization furnace under oxygen-deficient or oxygen-limited conditions, removing volatile substances (moisture, gases, tar, etc.) and ultimately leaving behind a solid substance rich in carbon. The combustion chamber of a carbonization furnace typically has an inlet / outlet connected to the furnace chamber for adding solid fuel. After combustion, residue is produced, requiring regular cleaning to ensure sufficient space in the combustion chamber. The conventional cleaning method involves using a shovel to remove the residue, which is time-consuming and labor-intensive. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a combustion chamber for a carbonization furnace that facilitates centralized collection and discharge of fuel residue, saving time and effort.

[0004] The technical solution of this utility model is as follows:

[0005] A combustion chamber of a carbonization furnace includes a combustion furnace body and a carrier box. The combustion furnace body has a furnace chamber inside, and a groove adapted to the carrier box is opened in the middle of the bottom of the furnace chamber. The carrier box is disposed in the groove, and the bottom of the furnace chamber is an inclined surface that slopes downward along the direction close to the groove. An inlet and outlet communicating with the groove are opened on one side of the combustion furnace body. The carrier box is a square box with an open top. A carrier for holding fuel is provided at the top opening of the carrier box, and a discharge port is provided at the bottom of the carrier box near the inlet and outlet side.

[0006] In a further technical solution, a number of protrusions are evenly spaced on the inclined surface of the furnace chamber.

[0007] In a further technical solution, the carrier includes multiple horizontal support rods positioned at the top opening of the carrier box.

[0008] In a further technical solution, a movable door is provided at the discharge port. The movable door is hinged to the side of the discharge port away from the inlet / outlet. When the movable door is in a horizontal state, the discharge port is closed, and the bottom surface of the movable door is flush with the bottom surface of the carrier box.

[0009] In a further technical solution, a pull ring is provided on the side of the carrier box near the entrance / exit.

[0010] In a further technical solution, the carrier box is provided with an inclined platform for the inclined discharge port.

[0011] In a further technical solution, the combustion furnace body is also provided with an air inlet and an exhaust outlet that connect to the furnace chamber.

[0012] The beneficial effects of this utility model are:

[0013] 1. The carrier box inside the furnace can be removed and placed in the slot. The support component on the carrier box can support the solid fuel together with the inclined surface at the bottom of the furnace. The residue after the solid fuel is burned can fall into the carrier box through the gaps in the support component, and the inclined surface of the furnace facilitates the concentrated fall of the residue into the carrier box. When it is necessary to clean the residue, pull out the carrier box from the inlet and outlet so that the bottom of the discharge port is no longer blocked, and most of the residue in the furnace can be easily discharged, ensuring that there is enough space in the combustion chamber, saving time and effort.

[0014] 2. The protrusions are used to support the solid fuel, which helps the solid fuel to be evenly distributed on the inclined surface of the furnace. After combustion, the residue can fall smoothly along the inclined surface to the carrier box.

[0015] 3. The movable door is supported by the groove before the carrier box is pulled out of the combustion furnace body, so that the movable door is closed and the residue at the discharge port falls into the groove and affects the movement of the carrier box relative to the groove. After the carrier box is pulled out of the combustion furnace body, the movable door loses its support and automatically opens to open the discharge port to discharge the residue, which is convenient to use.

[0016] 4. The inclined platform inside the container helps the residue to be concentrated and fall out of the discharge port. Attached Figure Description

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] Example:

[0025] like Figures 1-4As shown, a combustion chamber of a carbonization furnace includes a combustion furnace body 10 and a carrier box 20. The combustion furnace body 10 has a furnace chamber inside, with a groove adapted to fit the carrier box 20 in the center of the bottom of the furnace chamber. The carrier box 20 is disposed in the groove and can slide in and out relative to the groove. The bottom of the furnace chamber is an inclined surface sloping downwards along the direction close to the groove, with an inclination angle of 12-18 degrees, sufficient to allow residue to slide smoothly into the carrier box 20. An inlet / outlet 11 communicating with the groove is provided on one side of the combustion furnace body 10, and a furnace door 12 hinged to one side of the inlet / outlet 11 is used to open and close it. The carrier box 20 is... The top-opening square box 20 has a fuel-bearing support at its top opening. The support can be made of multiple horizontally arranged support rods 21 at the top opening of the box 20, with gaps between the support rods 21 for the residue after the solid fuel combustion to pass through. The bottom of the box 20 is provided with a discharge port on the side near the inlet / outlet 11. The combustion furnace body 10 is also provided with an air inlet 13 and an exhaust port 14 that connect to the furnace. The air inlet 13 is used to introduce reusable combustion gas, and the exhaust port 14 is used to discharge the waste gas generated after combustion in the furnace to a designated location for treatment.

[0026] In this embodiment, a pull ring 22 is provided on the side of the carrier box 20 near the entrance / exit 11, which makes it convenient for staff to use a hook-shaped tool to hook the pull ring 22 and pull the carrier box 20 out of the entrance / exit 11.

[0027] The working principle of the above technical solution is as follows:

[0028] The combustion chamber is used to provide high temperature for burning wood in the carbonization furnace under oxygen-deficient or oxygen-limited conditions. During operation, the furnace door 12 is opened, and solid fuel is put into the inclined surface of the furnace through the inlet 11 using a tool. At the same time, solid fuel is placed on the support rod 21 at the top of the carrier box 20. After ignition, the furnace door 12 is closed for combustion. The residue after combustion slides down the inclined surface of the furnace and falls into the carrier box 20 through the gap between the support rods 21. After combustion and cooling, the furnace door 12 is opened, and the carrier box 20 is pulled out using a tool so that the bottom of the discharge port is no longer blocked. The residue is discharged from the discharge port. When discharging, a tool can be used to sweep and assist in the discharge of the residue. The residue concentrated in the carrier box 20 can be quickly cleaned up.

[0029] In another embodiment, such as Figure 2 As shown, several cylindrical protrusions 15 are evenly spaced on the inclined surface of the furnace.

[0030] The protrusion 15 is used to support solid fuel, which is conducive to the uniform distribution of solid fuel on the inclined surface of the furnace. The cylindrical protrusion 15 has less obstruction, and the residue produced after combustion can fall smoothly along the inclined surface to the carrier box 20.

[0031] In another embodiment, such as Figure 3-4As shown, a movable door 23 is provided at the discharge port. The movable door 23 is hinged to the side of the discharge port away from the inlet / outlet 11. When the movable door 23 is in a horizontal state, it closes the discharge port, and the bottom surface of the movable door 23 is flush with the bottom surface of the carrier box 20.

[0032] Before the carrier box 20 is pulled out of the combustion furnace body 10, the movable door 23 is supported by the groove, so that the movable door 23 is closed to prevent the residue from the discharge port from falling into the groove and affecting the movement of the carrier box 20 relative to the groove. After the carrier box 20 is pulled out of the combustion furnace body 10, the movable door 23 loses its support and automatically opens to open the discharge port to discharge the residue, which is convenient to use.

[0033] In another embodiment, such as Figure 4 As shown, the container 20 has an inclined platform 24 with an inclined discharge port, and the hinge of the movable door 23 is located at the bottom of the inclined platform 24.

[0034] The inclined platform 24 inside the carrier box 20 facilitates the concentration of residue to the discharge port.

[0035] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
