Description

Technical Field

[0001] The utility model relates to the technical field of powder classifier feeding, in particular to a powder classifier feeding device. Background Art

[0002] Powder classifiers are widely used in coal mills, raw material intermediate drying mills and cement mill systems in new dry process cement production lines. They can be divided into three categories: three-separation powder classifiers, centrifugal powder classifiers and cyclone powder classifiers. During the working process of the powder classifier, a feeding device is required to add raw materials into the powder classifier.

[0003] According to the powder selection machine feeding device disclosed on the patent website (authorization announcement number: CN 214555338 U) as described in "The present application relates to the field of powder screening technology, and in particular to a feeding device for a powder selection machine, which includes a machine body, a turntable, a rotating shaft, a bracket, a motor, a feeding piece, a feeding pipe and a plurality of partitions, wherein the feeding pipe includes an inner tube and an outer tube, and the plurality of partitions are fixedly arranged between the inner tube and the outer tube along the length direction, and the inner tube and the outer tube are divided into a plurality of feeding channels; both ends of the inner tube are closed, one end of the feeding piece is used to communicate with the powder to be screened, and the other end is connected to the outer tube; the feeding pipe coaxially penetrates the top wall of the machine body along the vertical direction, the motor is arranged in the inner tube, and the end of the motor away from the output shaft is arranged on the top wall of the machine body through the bracket, and the end of the bracket away from the motor passes through the feeding piece and is arranged on the outside of the outer tube of the machine body; one end of the rotating shaft is coaxially arranged on the output shaft of the motor, and the other end coaxially extends into the machine body along the inner tube and is arranged through the end wall of the inner tube, and the rotating disk is coaxially arranged at one end of the rotating shaft extending out of the inner tube. The present application can make the powder material be thrown out more evenly."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model connects the feed pipe and the turntable through the provided throwing net and the rotating shaft, so that the feed section and the turntable can rotate synchronously, so that the powder has a certain centrifugal force when leaving the feed pipe, thereby increasing the initial velocity of the powder being thrown out, and at the same time, the powder is broken up again by the throwing net when the powder is thrown out of the turntable, so that the powder is thrown out more evenly. However, in actual use, the throwing net alone cannot ensure that the powder is evenly broken up. When the raw materials are damp and agglomerated, it is easy for the raw materials to not be broken up and remain on the surface of the turntable, which is not convenient for stable feeding of the raw materials and has certain limitations. Therefore, it is necessary to improve a feeding device of a powder selection machine to solve the above problems. Utility Model Content
