Description

Technical Field

[0001] The utility model belongs to the technical field of carbonization furnaces, and in particular relates to an energy-saving integrated activated carbon carbonization furnace. Background Art

[0002] The horizontal carbonization furnace is a carbonization equipment that adopts horizontal manufacturing process. Its structure meets the current environmental protection requirements. It has three layers, and the middle layer is made of high temperature resistant insulation material, which can always keep the temperature in the furnace from radiating. The furnace door is sealed with boiler packing high temperature insulation material, which prevents air from entering, achieving oxygen-free carbonization, and the carbonization rate is higher than that of conventional carbonization furnaces.

[0003] The advantage of the horizontal carbonization furnace lies in its environmental performance. The flue gas generated is fully utilized, the combustion exhaust gas can meet the emission standards, and there is no cooling wastewater containing ammonia. In addition, its carbonization time is relatively short, which is 5 times shorter than that of the earth kiln. The horizontal carbonization furnace is also equipped with a flue gas purification system, which is recycled through the flue gas purification system, and the combustible gas is returned to the bottom for full combustion, thereby reducing pollution to the environment.

[0004] However, when the existing horizontal carbonization furnace is in use, the position of the wood inside the furnace relative to the bottom heat source remains unchanged, resulting in different carbonization progress of the wood near the heat source and the wood far away from the heat source, which can easily cause low carbonization uniformity of the wood, affecting the quality and efficiency of the wood carbonization, and due to the uneven heating, it will also lead to increased fuel loss. Utility Model Content

[0006] To achieve the above objectives, the utility model adopts the following technical solution: an energy-saving integrated activated carbon carbonization furnace, comprising an outer shell, one end of the outer shell is connected to a furnace cover by bolts, an inner shell is arranged on the inner side of the outer shell, a fire grate is installed under the inner shell, the cavity between the inner shell and the outer shell is filled with a thermal insulation layer, a smoke exhaust pipe and a drain pipe which pass through the inner shell are respectively arranged on the upper and lower sides of the outer shell, a reduction motor is installed at one end of the outer shell, the reduction motor is driven and connected with a transmission mechanism, the transmission mechanism comprises a main shaft, a sun gear is installed on the main shaft, the sun gear is meshed and connected to a planetary gear, the planetary gear is meshed and connected to a gear ring, the gear ring is installed on the inner wall of the outer shell, the planetary gear is fixedly installed on a driven shaft, one end of the driven shaft is fixedly connected to a wood holding cylinder, and the driven shaft is rotatably installed on a planetary frame.

[0007] The beneficial effect of the utility model is that when the transmission mechanism transmits the power of the reduction motor, it can make multiple wood holding cylinders for holding wood revolve around the axis of the sun wheel and rotate around their own axes at the same time, thereby effectively turning the wood, achieving uniform heating of the wood, and effectively reducing fuel loss.

[0012] As a further improvement of the above technical solution: a plurality of outer rollers are rotatably mounted on the edge of the support plate, and the outer rollers are rollingly connected to the inner wall of the inner shell.

[0015] As a further improvement of the above technical solution: an annular groove structure is formed on the inner shell, and the outer roller is rollingly installed on the inner side of the annular groove.

[0017] To ensure that the wood is heated evenly;

[0018] As a further improvement of the above technical solution: the wood holding cylinder is a cylindrical structure with one end open, and the surface of the wood holding cylinder is evenly distributed with through-hole structures.

[0019] The beneficial effect of this improvement is that heat can enter the interior of the wood holding cylinder through the evenly distributed through holes on the wood holding cylinder, effectively heating the wood and ensuring that the wood is heated evenly.

[0020] In order to ensure the stability of the planetary gear rotation;

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0033] Embodiment 1:

[0034] like Figure 1—4 shows: an energy-saving integrated activated carbon carbonization furnace, comprising an outer shell 1, one end of the outer shell 1 is connected to a furnace cover 8 by bolts, an inner shell 3 is arranged on the inner side of the outer shell 1, a fire grate 9 is installed below the inner shell 3, a heat preservation layer 2 is filled in the cavity between the inner shell 3 and the outer shell 1, a smoke exhaust pipe 4 and a drain pipe 5 which pass through the inner shell 3 are respectively arranged on the upper and lower sides of the outer shell 1, a reduction motor 7 is installed at one end of the outer shell 1, the reduction motor 7 is driven and connected to a transmission mechanism 6, the transmission mechanism 6 comprises a main shaft 61, a sun gear 62 is installed on the main shaft 61, the sun gear 62 is meshedly connected to a planetary gear 64, the planetary gear 64 is meshedly connected to a gear ring 65, The gear ring 65 is mounted on the inner wall of the outer shell 1, and the planetary gear 64 is fixedly mounted on the driven shaft 66. One end of the driven shaft 66 is fixedly connected to the wood holding cylinder 10, and the driven shaft 66 is rotatably mounted on the planetary frame 63. When the transmission mechanism 6 transmits the power of the reduction motor 7, multiple wood holding cylinders 10 containing wood can revolve around the axis of the sun gear 62 and rotate around their own axis at the same time, thereby effectively turning over the wood, achieving uniform heating of the wood, and effectively reducing fuel loss. A support plate 11 is provided on the inner side of the inner shell 3, and a through-hole structure with a clearance fit with the wood holding cylinder 10 is opened on the support plate 11, and multiple inner rollers 1 are rotatably mounted on the support plate 11 on the peripheral side of the wood holding cylinder 10. 3. The inner roller 13 is rollingly connected to the outer surface of the wood holding cylinder 10. The inner roller 13 can provide stable support for the wood holding cylinder 10, ensuring that the wood holding cylinder 10 stably supports the wood. At the same time, the rolling connection method can ensure the smooth rotation of the wood holding cylinder 10. The edge of the support plate 11 is rotatably installed with multiple outer rollers 12. The outer rollers 12 are rollingly connected to the inner wall of the inner shell 3. Under the rolling support of the outer rollers 12, the support plate 11 can smoothly rotate on the inner side of the inner shell 3, while providing a stable supporting layer for the wood holding cylinder 10, avoiding affecting the smooth rotation of the wood holding cylinder 10. An annular groove structure is formed on the inner shell 3, and the outer rollers 12 are rollingly installed on the inner side of the annular groove. The design of the annular groove can limit the axial direction of the wood holding cylinder 10, thereby ensuring the safe and stable use of the wood holding cylinder 10. The wood holding cylinder 10 is a cylindrical structure with an opening at one end, and a through-hole structure is evenly distributed on the surface of the wood holding cylinder 10. Heat can enter the interior of the wood holding cylinder 10 through the evenly distributed through-holes on the wood holding cylinder 10 to effectively heat the wood and ensure the uniformity of heating of the wood. The planetary carrier 63 does not contact the sun gear 62 and the main shaft 61. The planetary carrier 63 can smoothly drive the planetary gear 64 to revolve, ensuring the stability of the rotation of the planetary gear 64. Support legs 14 are relatively arranged on both sides of the outer shell 1, and the support legs 14 can provide stable support for the device as a whole.

[0035] The working principle of the present technical solution is: open the furnace cover 8, put the wood into the wood holding tube 10 and then close the furnace cover 8, ignite the fire grate 9 and start the reduction motor 7. When the reduction motor 7 is running, the output shaft drives the main shaft 61 to rotate, and the main shaft 61 drives the sun gear 62 to rotate. When the sun gear 62 rotates, it meshes and drives the planetary gear 64 to rotate. The planetary gear 64 then meshes with the fixed ring gear 65, so that it rotates and revolves around the main shaft 61. At this time, the wood holding tube 10 coaxially installed on the driven shaft 66 with the planetary gear 64 keeps synchronous rotation and revolution with the planetary gear 64, so that the internal wood is evenly turned and heated. The water vapor and combustible gas generated in the carbonization process are discharged through the smoke exhaust pipe 4, and liquids such as wood tar are discharged through the drain pipe 5.
