Technical Field

The invention relates to ultrafine powder grading equipment, in particular to a feeding and distributing device.

Background

The technical research of the ultrafine powder has become a new hot subject, and according to the current situation and the national conditions, the powder with the particle size of less than 30um is called the ultrafine powder. In recent years, research and application of ultrafine powder have been rapidly developed, and the ultrafine powder material has been applied to almost all high, fine, sharp, and advanced disciplines and fields, and thus, the ultrafine powder material has been penetrated into all industrial fields and high-tech fields. The superfine powder concentrator is one of the important devices in the powder preparation industry, and the existing superfine powder concentrator comprises a shell, a driving device, a transmission shaft, a grading rotor, a powder collecting device, a feeding and distributing device, a flushing and dispersing device, a coarse powder collecting cone and a feeding pipe. The feeding and distributing device comprises a shaft sleeve and a plurality of spreading blades, wherein the spreading blades are radially and uniformly distributed on the circumferential surface of the shaft sleeve, and the shaft sleeve is arranged on the transmission shaft and is similar to a propeller structure. When the material scattering blade works, the material scattering blade is driven by the transmission shaft to rotate. The feeding and distributing device mainly has the functions of scattering the materials falling onto the scattering blades of the powder collecting device to the periphery and throwing the materials to the inner wall of the shell body to collide with the inner wall, so that agglomerated fine powder in the materials is dispersed. Because above-mentioned pay-off feed divider is similar to the propeller structure, on the one hand, the material that falls into on the spill material blade has partly direct to fall down from spilling between the material blade, leads to this part material to obtain not disperse, and on the other hand is thrown from spilling the material blade and is thrown to material all around also inhomogeneous, has influenced the dispersion of material, has consequently reduced the selection powder efficiency.

Disclosure of Invention

The invention aims to provide a feeding and distributing device, which can fully disperse materials, thereby being beneficial to improving the powder selecting efficiency of an ultrafine powder selector.

In order to solve the technical problem, the feeding and distributing device comprises a bottom plate, an aggregate cylinder and a plurality of material guide pipes, wherein a through hole is formed in the center of the bottom plate, a shaft sleeve is arranged on the through hole, the aggregate cylinder comprises an upper end, a peripheral surface and a lower end, the upper end and the lower end of the aggregate cylinder are both open, the lower end of the aggregate cylinder is arranged in the center of the bottom plate, the plurality of material guide pipes are uniformly distributed on the peripheral surface of the aggregate cylinder, one end, connected with the aggregate cylinder, of each material guide pipe is communicated with the aggregate cylinder, and a material guide plate is arranged.

Further, the material guide plate is of a channel steel structure.

Furthermore, the material guide plate is of an angle steel structure.

The number of the material guide pipes uniformly distributed on the circumferential surface of the aggregate cylinder body is 5-10.

When the feeding and distributing device is used, the shaft sleeve of the feeding and distributing device is arranged on the transmission shaft of the superfine powder concentrator. When the superfine powder separator works, the feeding and distributing device is driven by the transmission shaft to rotate, materials firstly enter the material collecting cylinder body and then enter the material guide plates arranged on the material guide pipes uniformly distributed on the circumferential surface of the material collecting cylinder body, the materials are distributed towards the inner wall surface of the shell of the superfine powder separator, the materials are dispersed after colliding with the inner wall surface of the shell, particularly, agglomerated fine powder is separated, and the separated fine powder enters the grading rotor of the superfine powder separator along with ascending airflow for separation. The materials firstly enter the material collecting barrel body and then are uniformly distributed to the material guide pipes and the material guide plates, and all the materials are scattered towards the inner wall surface of the shell of the superfine powder concentrator and collide with the inner wall of the shell, so that the materials and agglomerated fine powder in the materials are fully separated. Therefore, compared with the prior art, the feeding and distributing device can fully disperse materials, thereby being beneficial to improving the powder selecting efficiency of the superfine powder selecting machine.
