In addition, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.
[0027] This utility model embodiment provides a dual-chamber, dual-gate feeding device, such as...

[0034] In the embodiments of this application, such as Figure 1-6 As shown, the second plug-in structure 34 includes a fourth plug-in plate 341, a fifth plug-in plate 342, a sixth plug-in plate 343, and a seventh plug-in plate 344; the fourth plug-in plate 341 and the fifth plug-in plate 342 are arranged opposite to each other, and the fourth plug-in plate 341 is connected to the fifth plug-in plate 342 through a second connecting plate 345, forming a second plug-in cavity between the fourth plug-in plate 341, the fifth plug-in plate 342, and the second connecting plate 345; the sixth plug-in plate 343 and the seventh plug-in plate 344... The six and seven plug-in plates 343 are arranged opposite to each other, and the sixth plug-in plate 343 is connected to the third connecting plate 346 and the seventh plug-in plate 344 through the third connecting plate 346. A third plug-in cavity is formed between the sixth plug-in plate 343, the seventh plug-in plate 344 and the third connecting plate 346. The second connecting plate 345 is connected to the output end of the first housing 32. The third connecting plate 346 is connected to the input end of the upper coke chamber 2.

[0037] For example, the first water seal assembly 3 and the second water seal assembly 4 set the upper coking chamber 2 to a suspended state. The upper coking chamber 2 is supported on both sides of the bracket 1. A weighing sensor is installed between the bracket 1 and the upper coking chamber 2. The weighing sensor can be used to detect the internal material condition. When the material weight is detected to reach the set value, the slide valve 7 opens and begins to discharge the material to the lower coking chamber 5. When the weighing data shows that the material has been completely discharged, the slide valve 7 closes again. This cycle can achieve accurate weighing and control of the valve opening and closing.
[0038] For example, if the material weighing data shows that the material is still rising instead of decreasing after the gate valve 7 is opened, an alarm interlock value is set. After the interlock is triggered, the scraper conveyor and other related equipment are stopped to prevent the material from returning.
