[0025] Please see Figure 1 , Figure 2 and Figure 3 As shown in the figure, an embodiment of this utility model proposes a log batch dry distillation module, including at least two parallel dry distillation tanks 1 and a discharge cooling tank 4 connected to the discharge end of the dry distillation tanks 1. Specifically, as...Figure 3 As shown, the dry distillation tank 1 is a linear metal heating chamber with identical front and rear cavity diameters. Along the feed-to-discharge direction, it comprises a feed section 11, a main heating section 12, and a discharge section 13. The main heating section 12 is located within the high-temperature combustion chamber 100, while the feed section 11 and discharge section 13 are located outside the high-temperature combustion chamber 100. The high temperature in the high-temperature combustion chamber 100 transfers heat to the dry distillation tank 1, causing high-temperature carbonization of the logs inside, resulting in the finished dry distilled charcoal. Figure 1 and Figure 3 As shown, the top of the feeding box section 11 is equipped with a feeding port and a feeding gate valve 2 for controlling the opening and closing of the feeding port. The front end plate of the feeding box section 11 is equipped with a hydraulic propulsion device 3 for pushing the material in the feeding box section 11 forward to fill the main heating box section 12. The discharge port of the discharge box section 13 is connected to the discharge cooling box 4, and the discharge cooling box 4 is equipped with a discharge gate valve 5 for controlling the opening and closing of the discharge port. When feeding logs, the feeding gate valve 2 is opened, allowing the logs to enter the feeding box section 11 from the feeding port opened at the top of the feeding box section 11. When it is necessary to move the logs towards the rear of the container, the feed gate valve 2 closes, creating a seal at the feed inlet. The hydraulic propulsion device 3 advances the logs in the feed box section 11 forward one stroke and then returns. Then, the feed gate valve 2 is reopened, and logs are fed into the feed inlet. The feed gate valve 2 is then closed, and the hydraulic propulsion device 3 continues to advance the logs in the feed box section 11 forward one stroke. This process is repeated multiple times until the main heating box section 12 is full of logs. After carbonization, the discharge gate valve 5 opens the discharge port of the discharge box section 13. The hydraulic propulsion device 3 advances one stroke, pushing the finished charcoal from the rear of the carbonization box 1 out through the discharge port. Logs are then added from the feed inlet, and the hydraulic propulsion device 3 advances one stroke, gradually pushing all the finished charcoal out of the carbonization box 1. After all the finished charcoal has been pushed out, the carbonization box 1 is simultaneously filled with logs. In the embodiments of this utility model, the two distillation tanks 1 operate in batches. During the carbonization process in one distillation tank 1, the other distillation tank 1 discharges finished charcoal and feeds raw wood. The two distillation tanks 1 operate in a cycle in sequence to realize continuous and uninterrupted flow-type pyrolysis carbonization of raw wood by the distillation tanks.
[0026] Furthermore, in a preferred embodiment of this utility model, such as Figure 5As shown, the discharge cooling box 4 is equipped with a heat insulation plate 41 that divides the internal space into a lower chamber 42 and an upper chamber 43. The discharge port of the discharge box section 13 is located below the heat insulation plate 41, the gate of the discharge gate valve 5 is located in the lower chamber 42, and the electric drive mechanism of the discharge gate valve 5 is located in the upper chamber 43. In a preferred embodiment, the heat insulation plate 41 is made of thick asbestos board for insulation. The lower chamber 42 and the upper chamber 43 are respectively connected to a nitrogen cooling device, which provides low-temperature nitrogen to rapidly cool the lower chamber 42 and the upper chamber 43. The upper chamber 43 protects the electric drive mechanism of the discharge gate valve 5 to prevent damage from the high temperature released after the discharge port is opened. The lower chamber 42 rapidly cools the high-temperature finished charcoal discharged from the discharge port.
[0027] Furthermore, in a preferred embodiment of this utility model, such as Figure 6 As shown, the heat insulation plate 41 is provided with a gate slot 45 above the outlet of the corresponding discharge box section 13, allowing the gate of the discharge gate valve 5 to pass up and down. The outlets of the two distillation tanks 1 are both located in the lower chamber 42 and below the gate slot 45. For easy connection, the lower chamber 42 is provided with a docking part 44 that connects to the outlet of the discharge box section 13.
[0028] Furthermore, in a preferred embodiment of this utility model, such as Figure 7 As shown, the discharge gate valve 5 includes a valve seat 51, a gate 52, a servo motor 53, a bevel gearbox 54, and a lead screw 55. The inner side of the valve seat 51 has a groove 511, and the two sides of the gate 52 are slidably arranged in the groove 511. The servo motor 53 is connected to the lead screw 55 via the bevel gearbox 54, and the lower end of the lead screw 55 is connected to the gate 52. The upper end of the gate 52 has a bending plate 521, which has a lead screw through-hole and a lead screw sleeve 56 at the position corresponding to the lead screw 55. The lower end of the lead screw 55 is threadedly connected to the lead screw sleeve 56 and passes through the lead screw through-hole.
[0029] Furthermore, in a preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the bottom of the main heating box section 12 is provided with a fixed base 6, and a single row of vertical support frames 7 are arranged in a straight line on the fixed base 6. The tops of the vertical support frames 7 on two adjacent fixed bases 6 are connected to horizontal crossbars 71, and the main heating box section 12 is set on the horizontal crossbars 71. Figure 2 and Figure 4As shown, the top of the main heating box section 12 is equipped with a vertical exhaust pipe 8, and the left and right sides are equipped with horizontal exhaust pipes 81. The cracked gas generated during the high-temperature smoldering and carbonization of the logs is released through the vertical exhaust pipe 8 and the horizontal exhaust pipes 81 into the high-temperature combustion chamber 100 outside the dry distillation box 1, and burns on the outer wall of the main heating box section 12, heating the dry distillation box 1, so that the logs inside the dry distillation box 1 are calcined at high temperature until carbonized, thereby improving the thermal energy utilization rate.
[0030] Furthermore, in a preferred embodiment of this utility model, the distillation tank 1 includes a metal shell with a hollow packing jacket and a high-temperature resistant lining disposed within the hollow packing jacket. The high-temperature resistant lining is composed of ceramic fiber compressed blocks, and the metal shell is made of 253MA high-temperature resistant steel. It should be noted that in embodiments of this utility model, the structure of the feed gate valve 2 is the same as that of the discharge gate valve 5, differing only in their installation positions. Figure 3 As shown, the feed gate valve 2 is installed horizontally, and the discharge gate valve 5 is installed vertically.
[0031] In summary, this invention enables batch carbonization of logs by using at least two parallel-arranged pyrolysis tanks within a high-temperature combustion chamber. The carbonization process is uninterrupted. Through the coordination of a hydraulic propulsion device and inlet and outlet gate valves, the pyrolysis tanks can automatically feed and discharge, achieving continuous, uninterrupted flow-type pyrolysis carbonization of the logs, significantly increasing the carbonization yield. Furthermore, the outlet cooling box at the outlet end cools the high-temperature finished charcoal after discharge and provides cooling protection for the outlet gate valve, preventing damage to its electrical structure from the high temperature at the outlet end.
