Description

Technical Field

[0001] The present invention relates to the technical field of stirring equipment, in particular to stirring equipment used for bentonite production. Background Art

[0002] my country's bentonite mineral resources are very rich and widely distributed. Bentonite is hygroscopic and can expand several times after absorbing water. Generally, the performance of bentonite can be greatly improved after sodium blending. The production process of ordinary sodium-based bentonite can be divided into: mineral processing - aging - crushing - hopper - conveyor belt - drying - Raymond mill - air separation screening - finished product testing - packaging - storage and other process flows. The bentonite ore after artificial mineral processing needs to be crushed by a crusher or a vibrating screen. The particle size of the raw material after crushing is 0.3-0.5cm. The bentonite ore obtained by artificial screening is dried in a natural sunlight environment to keep the moisture content at about 11%-13%. It is then piled up by a forklift and stored, waiting for the next step of grinding. Sodium-based bentonite generally adopts dry sodiumization, and calcium-based bentonite mostly adopts wet sodiumization. If dry sodiumization is used, the effect is not obvious. The current process for producing high-performance bentonite is cumbersome and the degree of automation is low.

[0037] The working principle of the mixing equipment for bentonite production disclosed in the present invention is as follows: the bentonite ore is poured onto the top of the mounting frame 1 and enters the upper area of the mounting frame 1, the crushing motor 201 is started, the output shaft of the crushing motor 201 drives the main shaft 203 to rotate, drives the crushing knife 204 to rotate, and uses the crushing gear 202 to drive multiple main shafts 203 to rotate. The bentonite is transformed into small pieces of bentonite by the force between the crushing knives 204 and falls onto the filter plate 207. The small pieces of bentonite pass through the filter holes of the filter plate 207 and enter the lower area of the mounting frame 1. The fourth main shaft 203 rotates to drive the linkage rod 205 to rotate, and the filter plate 207 swings and drives the filter plate 207 to slide. The large pieces of bentonite slide into the fixed plate 218 through the filter plate 207, and the crushing gear 202 rotates to drive the transmission gear 208 to rotate. The transmission gear 208 drives the main bevel gear 210 to rotate through the vertical gear 209, and the main bevel gear 210 drives the secondary bevel gear 211 to rotate, and drives the first pulley 213 to rotate through the transmission shaft 212. The first pulley 213 drives the second pulley 215 to rotate through the conveyor belt 214, and then drives the parallel gear 216 and the feed rack 217 to rotate synchronously. The feed rack 217 is driven to rotate by gear transmission and belt transmission, and the bentonite on the fixed plate 218 is sent to the crushing knife 204 again through the feed rack 217 for crushing.

[0038] The transmission gear 208 rotates intermittently to drive the feeding gear 301 to rotate, and the feeding gear 301 drives the special-shaped plate 308 to rotate through the gear shaft 302. The rotation of the special-shaped plate 308 drives the upper material channel 310 and the lower material channel 311 to slide relative to each other, and the upper material channel 310 moves upward along the inclined surface of the upper opening and closing plate 303, the return spring 304 is compressed, the upper opening and closing plate 303 moves to both sides, and the lower material channel 311 moves downward along the inclined surface of the lower opening and closing plate 305, and the connecting spring 306 is compressed. The opening and closing plate 305 moves to both sides. At this time, the lower material channel 311 is directly above the drop port 413. Small pieces of bentonite fall into the mixing barrel 410 through the upper material channel 310, the lower material channel 311, and the drop port 413. At the same time, due to the relative sliding of the upper material channel 310 and the lower material channel 311, a certain amount of soda ash in the feeding box 307 falls into the mixing barrel 410. The transmission gear 208 continues to rotate, and the upper material channel 310 and the lower material channel 311 are reset under the action of the control spring 309.

[0039] The crushing motor 201 is turned off, the heating wire is energized, and the rotating motor 406 is started. The gear 2 408 is driven to rotate through the gear 1 407, and the stirring barrel 410 is driven to rotate. The soda ash and bentonite are mixed evenly by centrifugal force. At the same time, the heating wire is energized and heated to perform a drying process. After the preset drying time, the rotating motor 406 is turned off, the heating wire is de-energized, and the crushing motor 201 is started. The parallel gear 216 rotates to drive the grinding gear 401 to rotate, and the first bevel gear 403 is driven to rotate through the connecting shaft 402, and the second bevel gear 404 and the control shaft 405 are driven to rotate.
