Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate drying, in particular to drying equipment for producing heavy calcium carbonate. Background Art

[0002] When heavy calcium carbonate is produced, a drying device is required to dry it and evaporate the water in the calcium carbonate. For example, the drying device for calcium carbonate production disclosed in the publication number CN215524014U includes a drying tank, a main motor, a rotating shaft, a drying plate, a feeding pipe and a discharging pipe, and also includes a rake mechanism and a scattering mechanism. The scattering mechanism is composed of a scattering tank, a top pipe, a transmission shaft, a driving motor, a column rod, an arc plate and a shovel block;

[0003] Although the above equipment can achieve pre-dispersion and drying, during drying, the calcium carbonate powder is scraped up and falls from the edge or middle hole of the drying plate to the next plate body, and the heating time of the middle and edge positions of the plate body is inconsistent, resulting in uneven distribution of calcium carbonate on the next plate body, further resulting in uneven heating, affecting the heating efficiency of the equipment. At the same time, the equipment is an integrated design, and multiple drying plates share one rotating shaft. If a single rake rod assembly on the rotating shaft is damaged, all new rotating shafts need to be replaced, and the maintenance cost is high. Utility Model Content

[0026] Working principle: When in use, the second gear 303 located at the upper end of the second rotating shaft 302 is meshed with the first gear 203 located at the lower end of the first rotating shaft 202, and the second gear 303 located at the lower end of the second rotating shaft 302 is meshed with the second gear 303 on the second drying cylinder 4. When the motor 106 is started, the first rotating shaft 202 and the second rotating shaft 302 inside the first drying cylinder 3 and the second rotating shaft 302 inside the second drying cylinder 4 can be rotated through the first gear 203 cooperating with the second gear 303. The external calcium carbonate enters the inner side of the first shell 208 from the first feeding pipe 205. The rotation of the first rotating shaft 202 drives the cutting knife 204 to rotate, breaking up the damp calcium carbonate. Under the action of centrifugal force, the calcium carbonate enters the first discharging pipe 206, and the first discharging pipe 206 passes through The No. 1 solenoid valve 207 and the connecting pipe 5 are connected to the No. 2 feed pipe 307. Calcium carbonate enters the first drying cylinder 3 from the No. 2 feed pipe 307 and falls on the center of the heating disk 305. The rotating second shaft 302 cooperates with the push sheet 304 to do work on the calcium carbonate, so that the calcium carbonate moves from the center to the edge of the heating disk 305 under the cooperation of centrifugal force and the spiral groove 306, and then enters the No. 2 discharge pipe 308. The No. 2 discharge pipe 308 cooperates with the No. 2 shell 3010 and the connecting pipe 5 to connect with the No. 2 feed pipe 307 on the second drying cylinder 4. The second drying cylinder 4 and the first drying cylinder 3 are similar, so that the calcium carbonate undergoes multiple heating and drying processes, and moves from the center to the edge of the heating disk 305 during heating, so that the calcium carbonate is heated more evenly, thereby improving the drying effect of the equipment.

[0027] When maintenance is needed, the crushing cylinder 2, the first drying cylinder 3 and the second drying cylinder 4 are modularly designed, and are driven by a motor 106 without sharing a transmission shaft, thereby reducing the investment in the cost of the power components. By rotating the threaded connector on the crushing cylinder 2, the first drying cylinder 3 or the second drying cylinder 4, the first shell 208 or the second shell 3010 can lose its external fixation, thereby exposing the internal structure of the crushing cylinder 2, the first drying cylinder 3 and the second drying cylinder 4, making it convenient for the staff to carry out maintenance. Similarly, when the crushing cylinder 2, the first drying cylinder 3 or the second drying cylinder 4 is damaged, the staff can replace the crushing cylinder 2, the first drying cylinder 3 or the second drying cylinder 4 separately without replacing all the equipment, thereby reducing the cost required for equipment maintenance.
