Detailed implementation manner

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] The technical solutions provided by the present invention are as follows: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, in this embodiment, a drying device for processing light calcium carbonate includes a carrier frame 1 and an outer cylinder 2. The outer cylinder 2 is fixedly installed at the top of the carrier frame 1. An inner cylinder 3 is arranged inside the outer cylinder 2 and is used to carry the light calcium carbonate raw material. A screw blade 4 is arranged inside the inner cylinder 3 and is used to separate the light calcium carbonate raw material inside the inner cylinder 3. A feed inlet 5 and a discharge outlet 6 are respectively opened at the front and rear ends of the inner cylinder 3 and are used to input and discharge the light calcium carbonate raw material. A rotating mechanism 7 is arranged above the carrier frame 1 and is used to drive the inner cylinder 3 to rotate.

An adjusting mechanism 9 is arranged on one side of the inner cylinder 3 to clean the inside of the inner cylinder 3. An internal water storage mechanism 10 is arranged between the outer cylinder 2 and the inner cylinder 3 to recover and utilize thermal energy. After the light calcium carbonate enters the inner cylinder 3 through the feed inlet 5, with the inner cylinder 3 put into operation, the servo motor 11 drives the pinion 12 to rotate, so that the large gear 13 can drive the inner cylinder 3 to roll and rotate inside the outer cylinder 2. Thus, in the cooperation between the inner cylinder 3 and the screw blade 4, the light calcium carbonate raw material can be stirred, and at the same time, the heating mechanism 8 is put into operation. The hot air enters the inside of the long cylinder 17 from the outer connecting pipe 19 and can be evenly dispersed inside the inner cylinder 3 through the hole 18 subsequently, so as to dry the rolling light calcium carbonate raw material. At the same time, the hot air can be discharged from the outer connecting pipe 20, and thus the hot air is circulated for conveying. This structure can effectively improve the dispersion of the light calcium carbonate raw material, thereby improving the absorption of heat and effectively preventing caking phenomenon.

[0030] As Figure 1 and Figure 4 shown, the rotating mechanism 7 includes a servo motor 11. The servo motor 11 is fixedly installed at the top of the carrier frame 1.

By providing the rotating mechanism 7, with the servo motor 11 driving the pinion 12 to rotate, the large gear 13 can drive the inner cylinder 3 to roll and rotate inside the outer cylinder 2.

By providing the heating mechanism 8, as hot air enters the inside of the long cylinder 17 from the outer connecting pipe 19, it can be evenly dispersed inside the inner cylinder 3 through the first hole 18 subsequently, so as to dry the tumbling light calcium carbonate raw materials. At the same time, the hot air can be discharged from the outer connecting pipe 20, thereby realizing the circulation of hot air transportation. A dust - proof part is provided at one end of the outer connecting pipe 20 inside the inner cylinder 3, and the air - energy dryer mentioned in this article is an existing and mature technology, so the principle and structure will not be elaborated in detail here.

A fixing frame 22 is fixedly installed on the outer side of the outer sleeve 21, and the fixing frame 22 is fixedly installed on the outer side of the outer cylinder 2. An inner sleeve 23 is inserted inside the outer sleeve 21. Second holes 24 and third holes 25 are respectively formed on the outer sides of the outer sleeve 21 and the inner sleeve 23. A second large gear 26 is fixedly installed on the outer side of the inner sleeve 23, and a second small gear 27 is meshed and connected to the outer side of the second large gear 26. The second small gear 27 is fixedly installed on the outer side of the rotating shaft of a second servo - motor 28, and the second servo - motor 28 is fixedly arranged at one side position of the fixing frame 22. One end of the inner sleeve 23 is fixedly connected to a corrugated pipe 29, and the other end of the corrugated pipe 29 is fixedly connected to a water pump 30. The water pump 30 is fixedly installed on the bearing frame 1.

The inner sleeve 23 and the second holes 24 have the same diameter. By providing the adjusting mechanism 9, as the second servo - motor 28 drives the second small gear 27 to rotate, the second large gear 26 drives the inner sleeve 23 to rotate inside the outer sleeve 21, so that the hollow shafts among the second holes 24, the third holes 25 and the first hole 18 are on the same axis. Subsequently, during the operation of the water pump 30, water can be transported into the corrugated pipe 29, and then the water is sprayed out through the second holes 24, the third holes 25 and the first hole 18, so as to clean the inside of the inner cylinder 3.

[0033] As Figure 2As shown, the internal water storage mechanism 10 includes a water guide pipe 31 which is fixedly installed on the outer side of the water pump 30.

By providing the internal water storage mechanism 10, with the high temperature generated inside the inner cylinder 3, the water arranged in the water storage tank 32 can absorb the heat. Thus, when the subsequent hot water is used to clean the inside of the inner cylinder 3, the cleaning work of the residues can be improved to a certain extent.

[0034] The utility model provides a drying device for processing light calcium carbonate, and the specific working principle is as follows:

[0035] During the use of the device, the calcium carbonate raw material can be poured into the inside of the inner cylinder 3 through the feed port 5. Then, as the servo motor one 11 drives the pinion one 12 to rotate, the large gear one 13 can drive the inner cylinder 3 to roll and rotate inside the outer cylinder 2. Thus, in the cooperation between the inner cylinder 3 and the auger blade 4, the light calcium carbonate raw material can be stirred. During this period, by starting the air energy dryer, the hot air enters into the inside of the long cylinder part 17 from the outer connecting pipe one 19, and then can be evenly dispersed into the inside of the inner cylinder 3 through the hole one 18, so as to dry the rolling light calcium carbonate raw material. At the same time, the hot air can be discharged from the outer connecting pipe two 20, thus realizing the circulating hot air transportation. The heat generated during this period enables the water arranged in the water storage tank 32 to absorb the heat. Then, the dried light calcium carbonate raw material can be discharged from the inner cylinder 3 through the discharge port 6. Then, the servo motor two 28 drives the pinion two 27 to rotate, so that the large gear two 26 drives the inner sleeve 23 to rotate inside the outer sleeve 21. Thus, the hollow shafts among the hole two 24, the hole three 25 and the hole one 18 are on the same axis. Subsequently, during the operation of the water pump 30, water can be conveyed into the corrugated pipe 29. Thus, the water sprays out through the hole two 24, the hole three 25 and the hole one 18, so as to clean the inside of the inner cylinder 3.
