Description

Technical Field

[0001] This utility model belongs to the field of calcium carbonate feeding technology, and in particular relates to an automatic feeding device in calcium carbonate production. Background Technology

[0002] In the calcium carbonate production process, the automatic feeding device is a system that integrates mechanical conveying, metering control and automated management functions. It is used to accurately and continuously transport calcium carbonate raw materials or intermediate materials to the next production stage according to the set process parameters. Its core function is to replace manual feeding, realize the automation, continuity and precision of the production process, thereby improving production efficiency, stabilizing product quality and reducing labor costs and labor intensity.

[0003] For example, Chinese patent CN223015488U discloses an automatic feeding device for the production of food-grade calcium carbonate. The device includes a storage tank housing and a movable support mounted on the bottom of the housing for movement. The bottom of the storage tank housing has a discharge port. The bottom of the movable support is connected to a movable plate via a drive mechanism. The top of the movable plate is connected to a closing plate via a telescopic mechanism. A sealing layer corresponding to the discharge port is fixed to the top of the closing plate. This automatic feeding device for food-grade calcium carbonate production, through the combined use of the telescopic mechanism, drive mechanism, closing plate, and sealing layer, allows the closing plate and sealing layer to stably align upwards and close the discharge port. The drive mechanism automatically aligns the sealing layer with the discharge port, saving on the equipment's discharge path, thus avoiding raw material waste and enhancing the device's discharge efficiency.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use. For example, if the storage environment has high humidity, the material is prone to absorbing moisture and agglomerating into clumps. When clumps form, they accumulate at the bottom of the silo or at the discharge pipe, causing feeding interruptions and requiring frequent shutdowns for cleaning, thus affecting production continuity. Therefore, we propose an automatic feeding device for calcium carbonate production. Utility Model Content

Through the setting of a second support plate and an auger, it ensures that the auger can rotate on the bottom surface of the second support plate, allowing the auger to clear blockages. Through the setting of a first gear groove, a first bevel gear, and a second bevel gear, it ensures that when the two second bevel gears rotate, the two second bevel gears will respectively drive the two first bevel gears in the two first gear grooves. The rotation causes the two first bevel gears to drive the two crushing rollers to rotate. Through the set second gear slot, third bevel gear, and fourth bevel gear, it is ensured that when the fourth bevel gear rotates, it will drive the third bevel gear to rotate in the second gear slot, which in turn drives the auger to rotate. Through the set drive component, it is possible for the user to drive the two second bevel gears and the fourth bevel gear to rotate. This solves the problem that when materials form clumps, the clumps will accumulate at the bottom of the hopper or at the discharge pipe, causing feeding interruptions, requiring frequent shutdowns for cleaning, and affecting the continuity of production.

[0066] Working principle:

[0067] In use, the user starts the motor 19, causing the output shaft of the motor 19 to drive one of the fifth bevel gears 14 to rotate in one of the third gear slots 13. This causes one of the fifth bevel gears 14 to drive one of the sixth bevel gears 16 to rotate in one of the third gear slots 13. One of the sixth bevel gears 16, via the second connecting rod 18, drives another sixth bevel gear 16 to rotate, which in turn drives another fifth bevel gear 14 to rotate in the third gear slot 13. When both fifth bevel gears 14 rotate, they will respectively drive two second bevel gears 6 to rotate via the two first connecting rods 15. These two second bevel gears 6 will then respectively drive two first bevel gears 5 to rotate in the two first gear slots 4. During rotation, the two first bevel gears 5 will drive the two crushing rollers 3 to rotate, allowing the two crushing rollers 3 to crush the agglomerated material. At the same time, when the motor 19 starts, the output shaft of the motor 19 will also drive the first sprocket 20 to rotate, causing the first sprocket 20 to drive the second sprocket 23 to rotate through the chain 24. The second sprocket 23 will drive the rotating rod 22 to rotate in the rotating groove 21, causing the rotating rod 22 to drive the fourth bevel gear 11 to rotate in the second gear groove 9, causing the fourth bevel gear 11 to drive the third bevel gear 10 to rotate in the second gear groove 9. When the third bevel gear 10 rotates, it will drive the auger 8 to rotate in the discharge port of the housing 1, ensuring that the user can drive the two second bevel gears 6 and the fourth bevel gear 11 to rotate at the same time, preventing the material from clogging.

[0068] When in use, the user activates the electric telescopic rod 26, which causes the output shaft of the electric telescopic rod 26 to drive the tension wheel 27 to move, causing the tension wheel 27 to press the chain 24, ensuring that the user can adjust the tension of the chain 24.
