[0031] Please see the attached Figure 1 -Attached Figure 5 The primary carbonization zone 2 includes a carbonization heating furnace 204. The carbonization heating furnace 204 is provided with a first temperature sensor 203, a first resistance wire heating device 202, and a first material level meter 201 from top to bottom.

[0032] Specifically, the carbonization heating furnace 204 is the core component of the primary carbonization zone 2 , and its internal structure is sequentially provided with a first temperature sensor 203 , a first resistance wire heating device 202 and a first material level meter 201 from top to bottom. The first temperature sensor 203 is used to monitor the temperature in the furnace in real time. When the temperature reaches a set value such as 400°C, a feedback signal is sent to the control system 12 to ensure that the straw undergoes carbonization reaction at an appropriate temperature. The first resistance wire heating device 202 provides the necessary heat energy for the carbonization process. Through the heating effect of the resistance wire, the straw completes preliminary carbonization in a high-temperature environment. The first lower material level meter 201 is installed near the bottom of the carbonization heating furnace 204 and is used to monitor the material level height of the carbonized material. When the lower material level meter detects that the material reaches a certain height, it sends a signal to the control system 12 to trigger subsequent discharging operations. The discharge port is set at the bottom of the carbonization heating furnace 204 and is used to discharge the carbonized straw into the cooling and filtration area 3; the discharge port is linked to the electric control baffle, which is opened or closed under the command of the control system 12 to realize the timed and quantitative transportation of the material, ensuring that the carbonized straw can smoothly enter the next processing link; the electric control baffle is installed at the discharge port below the cooling and filtration area 3 and is controlled by the control system 12.

[0033] When the straw charcoal in the cooling and filtering zone 3 completes the cooling and filtering process, and the second lower material level meter 302 detects that the material level has reached the set value, the control system 12 issues a command, and the electric control baffle opens, allowing the material to be transported downward to the mixing and stirring zone 4. The setting of the electric control baffle effectively avoids the disordered accumulation of materials and ensures the continuity and stability of the production process; the filter screen 301 is located inside the cooling and filtering zone 3, in the middle of the material conveying path. Driven by the vibration device, the filter screen 301 continuously vibrates, removing impurities in the straw charcoal through screening to improve the purity of the material; the aperture size of the screen 301 can be selected according to the process requirements to ensure that the final product meets the quality standards; the second lower material level meter 302 is installed below the filter screen 301 to monitor the material level of the straw charcoal after cooling and filtration. When the second lower material level meter 302 detects that the material level has reached the preset height, it sends a signal to the control system 12 to prompt that the material is ready for the next step, thereby achieving seamless connection of the automated production process.

[0034] Please see the attached Figure 1 -Attached Figure 5 The first material level meter 201 is arranged below the carbonization heating furnace 204. The first material level meter 201 is connected to the control system 12 through electronic control. The mixing and feeding stirring area 4 is provided with a feed port, a silica sol feeding port 401, an upper material level meter 404 and a mixing and stirring device. The feed port is the discharge port below the carbonization heating furnace 204, and the feeding port is the silica sol feeding port 401. The silica sol feeding port 401 is evenly distributed on the pipe connected to the silica sol medicine box.

[0035] Specifically, a first material level gauge 201 is disposed below the carbonization heating furnace 204 and is used to monitor the material level within the carbonization heating furnace 204. When the carbonization process is complete and the material level reaches the set value, the first material level gauge 201 is electrically connected to the control system 12 and sends a signal to the control system 12, indicating that the material is ready for the next step. Upon receiving the signal, the control system 12 opens the discharge port at the bottom of the carbonization heating furnace 204, allowing the material to flow downward to the cooling and filtration zone 3. The feed port serves as the material inlet for the mixing, feeding, and stirring zone 4 and is connected to the discharge port below the carbonization heating furnace 204 to receive the cooled and filtered straw charcoal from the cooling and filtration zone 3. The design of the feed port ensures that the material can smoothly enter the mixing, feeding, and stirring zone 4 for subsequent mixing and stirring steps. The silica sol feed port 401 is used to quantitatively inject silica sol into the mixing, feeding, and stirring zone 4. Silica sol acts as a binder, which can improve the strength and stability of the final carbon-based water dispenser.

[0036] The location and structural design of the silica sol feeding port 401 ensure that the silica sol can be evenly mixed with the straw charcoal and clay. The upper level meter 404 is installed inside the mixing and feeding stirring zone 4 to monitor the material level of the mixed material. When the material received by the feed port and the silica sol injected by the silica sol feeding port 401 reach the set material level, the upper level meter 404 sends a signal to the control system 12 to indicate that the material is ready for stirring operation.

[0037] The mixing and stirring device includes a spiral stirring blade 402 and a first motor 403. The first motor 403 drives the spiral stirring blade 402 to run at a set speed, such as 30 rpm, to fully stir the materials in the mixing and stirring zone 4 to ensure that the straw charcoal, clay and silica sol are evenly mixed to form a uniform slurry. The operation of the mixing and stirring device is controlled by the control system 12, and the stirring time can also be set according to the process requirements.

[0039] Specifically, the first motor 403 is connected to the control system 12 via an electric control, and is started and stopped by the control system 12. When the control system 12 receives a signal from the upper material level meter 404 and determines that the material in the mixing and adding stirring zone 4 has reached the set material level, it will start the first motor 403 to drive the spiral stirring blade 402 to run at a set speed to stir the material in the mixing and adding stirring zone 4; the feed port is set at one end of the extrusion tank 5 as the inlet of the material, and is connected to the discharge port below the mixing and adding stirring zone 4 to receive the mixed slurry. The hydraulic rod 501 is installed in the extrusion tank 5 and is connected to the control system 12 via an electric control. An adapted extrusion head is installed at its end. An electromagnetic valve (not shown in the figure) is provided in the extrusion groove 5 of the extrusion head diameter, and a guide column (not shown in the figure) is coaxially provided behind the electromagnetic valve. The guide column is adapted to the diameter of the tubular carbon-based water injector body 9 to be finally produced. After the slurry enters the extrusion groove 5, the control system 12 controls the electromagnetic valves to close and then starts the hydraulic rod 501. The hydraulic rod 501 applies pressure to the slurry to cause it to be plastically deformed in the extrusion groove 502. The extrusion groove 502 is used to extrude and shape the slurry. After being pushed, the shaped billet is formed into a tubular structure through a hole made by the guide column and then goes to the secondary carbonization zone 6.
