Description

Technical Field

[0001] The utility model relates to an automatic weighing and feeding mechanism of a continuous carbonization furnace. Background Art

[0002] One process in the production of carbon molecular sieves involves extruding a properly mixed material into strips and then feeding it into a continuous carbonization furnace for high-temperature carbonization. The process involves intermittently discharging the material from the hopper through a pneumatic gate valve controlled by a time relay for a few seconds. Because the extruded material contains a certain amount of moisture, some of the material can form lumps. Each discharge cycle lasts only a few seconds, and this lumpy material affects the weight of each discharge, resulting in inconsistent discharge speeds. Furthermore, the lumpy material can form a bridge at the top of the valve, causing valve blockage that is undetectable. Blockage can only be detected by temperature changes within the carbonization furnace, which can take over fifteen minutes. Utility Model Content

[0020] A weighing sensor 4 is provided under the weighing bin 7. The weight of the weighing bin 7 falls on the weighing sensor 4 through the upper silicone flexible connection 5 and the lower silicone flexible connection 10. The weighing sensor 4 is no longer affected by the self-gravity of the weighing bin 7 and the gravity of the connecting parts.

[0021] In one embodiment, three weighing sensors 4 are provided and evenly distributed at the bottom of the weighing bin 7. A storage bin bracket 2 is provided on the storage bin 1 to support the storage bin 1 and bear its gravity so that it does not affect the weighing bin 7. A base bracket 8 is provided above the carbonization furnace head to support the storage bin bracket 2. The weighing bin 7 is located on the base bracket 8 but is not connected to the base bracket 8. The weight is borne by the upper silicone flexible connector 5 and the lower silicone flexible connector 10.

[0022] In one embodiment, a gate valve 3 is further provided below the storage bin 1.

After weighing is completed, the discharge gate valve 9 is opened through the programmable controller, and the material in the weighing bin 7 flows into the carbonization furnace head 13 through the discharge gate valve 9 and the feed port 12 of the carbonization furnace. When the weighing sensor 4 senses that the weight in the weighing bin 7 is reset, the discharge gate valve 9 is closed, and the two-stroke feeding gate valve 3 is continued to be opened for discharge, and the cycle is repeated.
