Description

Grading machine

Technical Field

The utility model relates to a powder equipment, in particular to powder grading plant grader

Background

The existing classifier is shown in the attached figure 1 of the specification and comprises a bearing seat 1, a classifier neck 2, a bearing seat isolation sleeve 3, a bearing seat lower support ring 4, a support rib 5, a classifying wheel 6 and a shell 7. In the powder classifying process, the finer powder passes through the classifying wheel 6 and the gap of the support rib 5 from the inner part of the classifier shell 7 in the arrow direction, enters a channel formed by the inner side of the classifier neck 2 and the outer side of the bearing seat isolating sleeve 3 and is discharged from the discharge hole of the classifier neck 2 in the arrow direction. Generally, powder equipment applied to industries such as food, medicine, chemical industry and the like requires that the parts contacting with powder are made of stainless steel or non-metallic materials, and the bearing seat isolation sleeve is made of different materials for avoiding the surface contact of the powder and a coaxial bearing seat, and the bearing seat can be made of one material of carbon steel. However, the existing classifier has the following defects: firstly because bearing frame spacer 3 and bearing frame lower support ring 4, brace rod 5 all weld in the inboard of grader neck 2, lead to the inner structure of grader neck 2 complicated, be not convenient for internal surface machining and processing, consequently the product quality is difficult to guarantee, moreover manufacturing cost is high. Secondly, some special industries require that the powder can not contact with the metal surface, so special materials such as ceramics and the like need to be lined inside the machine neck 2, and the existing structure is difficult to realize the requirement of lining. Thirdly, the supporting ribs block the flowing channel of the powder, the permeability of the grader is influenced, the powder can also erode and abrade the supporting ribs 5, the supporting ribs 5 can be caused to lose effectiveness early, and the durability of the equipment is influenced.

Disclosure of Invention

An object of the utility model is to the not enough of prior art scheme, through the improvement to its structure, provide a new grader structure and satisfy the needs of society.

The technical scheme of the utility model is that:

a grader comprises a grading wheel 6, a shell 7, a new bearing seat 8, a new grader neck 9 and a new bearing seat sleeve 10, wherein the inside of the new grader neck 9 is not provided with a bearing seat isolation sleeve 3, a bearing seat support ring 4 and a support rib 5; the disc connected with the new classifier neck 9 on the new bearing seat 8 is positioned at the middle upper part of the new bearing seat 8, the new bearing seat sleeve 10 is assembled or bonded on the outer circle of the lower part of the new bearing seat 8, and the new bearing seat 8 extends into the new classifier neck 9 and is fixed through bolts. The material of the new bearing housing sleeve 10 may be determined by the user's requirements and may be stainless steel or other non-metallic materials.

The utility model discloses the grader during operation, finer powder passes classification wheel 6 according to the arrow direction by the inside of grader casing 7, and the passageway that gets into new grader neck 9 inboard and new bearing frame sleeve pipe 10 excircle formation is discharged by the discharge gate of new grader neck 9 along the arrow direction again.

The utility model removes the bearing seat isolation sleeve 3, the bearing seat lower support ring 4 and the support rib 5 through the improvement and special combination of the new bearing seat 8, the new grader neck 9 and the new bearing seat sleeve 10, so that the interior of the new grader neck 9 is neat and transparent, and the mechanical processing and the surface polishing treatment are convenient; no supporting rib is blocked in the channel, so that abrasion is avoided, and simultaneously, the lining of the non-metal material is very convenient. Through practical application, the scheme can meet most requirements of the powder industry, and is high in reliability and good in economical efficiency.
