Description

Technical Field

[0001] The utility model belongs to the technical field of air classifiers, and particularly relates to a continuous feeding device for an air classifier. Background Art

[0002] An air classifier, a cyclone separator, a dust collector and a draft fan form a complete set of comminution system. After being filtered and dried, compressed air is sprayed into the comminution chamber at a high speed through a Laval nozzle. At the intersection of multiple high-pressure airflows, materials are repeatedly collided, rubbed and sheared to be comminuted. The comminuted materials move to the classification area along with the upward airflow under the suction of the fan. Under the powerful centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. The fine particles meeting the particle size requirements enter the cyclone separator and the dust collector through the classification wheel for collection, and the coarse particles drop to the comminution area to continue comminution.

[0003] When feeding materials to the existing air classifier, it is mainly manually controlled, which consumes a large amount of labor and often results in low comminution efficiency due to untimely feeding. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a continuous feeding device for an air classifier, which solves the problems that when feeding materials to the existing air classifier, it is mainly manually controlled, which consumes a large amount of labor and often results in low comminution efficiency due to untimely feeding.

One end of the classifier main body is provided with a feed inlet, and the other end is provided with a discharge outlet. The feeding pipe is arranged above the classifier main body, and the discharge opening of the feeding pipe is aligned with the feed inlet. A closing plate is hinged at the discharge outlet of the classifier main body, and the closing plate is adapted to the discharge outlet. An installation frame is fixedly connected to one side surface of the classifier main body. The linkage assembly includes a cylinder, the cylinder is installed in the installation frame, the output end of the cylinder is fixedly connected with a connecting block, the bottom end of the connecting block is hinged with a connecting rod, a fixing block is fixedly connected to one side surface of the closing plate, and one end of the connecting rod is hinged with the fixing block.

[0007] One side of the inner wall of the feed inlet is hinged with a partition board, and the other side of the inner wall is fixedly connected with a matching baffle. Both ends of the partition board are fixedly connected with support rods, the support rods are arranged inside the classifier main body and are rotationally matched with it. One end of the support rod is fixedly connected with a matching plate, and the matching plate is arranged outside the classifier main body.

[0008] On both sides of one end of the closing plate, connecting plates are fixedly connected. One end of the connecting plate is fixedly connected with a linkage plate, and one end of the linkage plate is fixedly connected with one end of the mating plate.

[0009] A fixing frame is fixedly connected to the periphery of the discharge opening of the blanking pipe. Fixing plates are fixedly connected to both ends of the fixing frame.

[0011] The utility model has the following beneficial effects:

[0012] By arranging a closing plate, a mating baffle, a partition plate, a mating plate, a linkage baffle, a mating rod and a linkage assembly, after the materials in the crusher are crushed, the air cylinder is used to drive the connecting block to move downward, and then the closing plate is driven to open by the connecting rod and the fixing block, so that the materials in the crusher are discharged. When the closing plate opens, the linkage plate is driven to move upward through the connecting plate, and then the partition plate is driven to move through the mating plate and the support rod, so that one end of the partition plate is attached to the mating baffle, blocking the feeding port. When the connecting block moves, the linkage baffle is driven to open through the mating rod by the linkage rod, so that the materials in the blanking pipe fall out from the discharge port and fall onto the partition plate from the feeding port; after the discharging is completed, the air cylinder is used to drive the closing plate to retract and close. Under the action of the linkage rod and the mating rod, the linkage baffle is simultaneously driven to close, so that the blanking pipe stops discharging. When the closing plate closes, the partition plate is driven to move through the linkage plate, so that the materials on the partition plate fall into the crusher for crushing treatment. This process is repeated continuously, thereby realizing continuous automatic feeding and improving the crushing efficiency.
