[0052] Working principle: When using this device, the controller is used to set the weight of the required refractory powder, and the refractory powder is added to this device from the feed pipe 5. The refractory powder enters the automatic weighing bin 3, and the refractory powder falls from the middle position of the scraping device onto the weighing plate 18 in the weighing device. The weighing sensor 17 senses the refractory powder above the weighing plate 18 and starts to weigh the refractory powder that falls onto the weighing plate 18. When the weighing sensor 17 senses that the refractory powder on the weighing plate 18 reaches the set value, the addition of the refractory powder is stopped, and the motor 23 is started. The output end of the motor 23 rotates to drive the motor 23 fixedly connected to it. The worm 19 rotates, and the worm 19 drives the worm wheel 22 meshing with it to rotate.

The warehouse door 9 drives the weighing plate 18 above it to rotate synchronously through the two connecting blocks 14. At this time, the refractory powder that has been weighed above the weighing plate 18 is blocked by the automatic weighing bin 3 when the weighing plate 18 rotates synchronously, and is scraped off by the automatic weighing bin 3. The lower end opening of the dynamic weighing silo 3 falls into the mold. The automatic weighing silo for refractory material production can automatically weigh the added refractory powder and feed the weighed refractory powder into the mold through the setting of the weighing device and the switch device, which reduces the labor intensity, increases the work efficiency, and improves the practicality of the device. At this time, the two hydraulic telescopic rods 10 are started by the controller 4, and the telescopic ends of the two hydraulic telescopic rods 10 move downward, driving the inner annular plate 11 fixedly connected to the telescopic ends to move downward synchronously, and the inner annular plate 11 drives the outer annular scraper plate 13 to move downward synchronously through the four connecting columns 12, and the switch device is opened. The refractory material powder adhering to the inner wall of the lower end of the automatic weighing silo 3 is scraped off, so that the weight of the refractory material powder that falls is the same as the weight of the refractory material powder when weighing. By setting the scraping device, the refractory material powder adhering to the inner wall of the automatic weighing silo during use is scraped off, so that the weight of the refractory material powder obtained is consistent with the weight of the refractory material powder weighed. After that, the weight of the refractory material powder obtained each time is controlled to be consistent, thereby ensuring the consistency of the quality of each product, preventing the weight of the powder added to the mold each time from being inconsistent, resulting in the problem of poor consistency in the quality of the refractory products produced, and improving the quality of refractory products produced by the device.
