Description

Grading wheel

Technical Field

The utility model relates to a powder equipment, in particular to grading wheel of powder equipment.

Background

The prior grading wheel is shown in the attached figure 1 of the specification and consists of a main framework 1, blades 2, a sunken blade supporting plate 3, a blade supporting plate 4 and a bottom plate 5. Sunken formula blade supporting disk 3, blade supporting disk 4 overlap respectively on main skeleton 1, and blade 2 distributes the breach location through circumference on main skeleton 1, sunken formula blade supporting disk 3, blade supporting disk 4, the bottom plate 5, welds into whole with them.

The grading wheel is a core component on a grading machine of powder grading equipment, powder particles are graded in thickness by the aid of the rotary grading wheel, and for part of superfine powder, the grading requirement can be met only by the aid of a higher rotating speed, linear speed of the blade 2 is higher at a high rotating speed, corresponding centrifugal force is increased, the blade 2 is easy to bend and deform outwards at a position between blade supporting disks, accordingly, rotation precision of the grading wheel is affected, grading is accurate, and even the grading wheel is damaged, and accordingly, the bending resistance of the blade 2 of the grading wheel is improved by means of encrypting the blade supporting disks technically. In the conventional grading wheel structure, the sunken blade support plate 3 and the blade support plate 4 are arranged accordingly.

The existing grading wheel has the following defects: firstly, the sinking type blade supporting disk 3 and the blade supporting disk 4 need a plurality of processes and multiple materials in the manufacturing process due to the complex structure, which causes the increase of material cost and processing cost and influences the manufacturing efficiency; and secondly, too many supporting rib plates can also influence the permeability and regularity inside the grading wheel, so that more powder particles are easily accumulated in the grading wheel in the working process of the grading wheel, the grading wheel is inconvenient to clean, and the rotating balance of the grading wheel can be 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 classification wheel and satisfy the needs of society.

The technical scheme of the utility model is that:

a grading wheel comprises a main framework 1, blades 2, a blade supporting ring 6, a blade supporting disk 4 and a bottom plate 5; the blade supporting ring 6 and the blade supporting disk 4 are respectively sleeved on the main framework 1; the blade 2 is positioned by the main framework 1, the blade supporting disk 4, the blade supporting ring 6 and the circumferentially distributed gap on the bottom plate 5 and is welded with the main framework, the blade supporting disk, the blade supporting ring and the bottom plate into a whole; blade supporting disk 4 cover on the excircle of main frame 1, be located the middle part of main frame 1, the upper and lower end of blade supporting disk 4 have blade support ring 6 respectively, bottom plate 5 covers on the excircle of main frame 1 lower extreme, blade 2 distributes in the breach of the circumference equipartition of blade support ring 6, blade supporting disk 4 and bottom plate 5 to weld into whole with them.

Namely, the rest blade supporting disks 4 and the sunken blade supporting disk 3 are all changed into the blade supporting ring 6 except for reserving one blade supporting disk 4 in the middle of the grading wheel. Therefore, the permeability in the grading wheel is better, powder accumulation in the working process is reduced, stable operation can be ensured, the manufacturing is simpler, the materials are less, and the cost is reduced.

Drawings

Fig. 1 is a current grading wheel structure, fig. 2 is a sunken blade supporting disk 3 structure, fig. 3 is a grading wheel blade supporting disk 4 structure, fig. 4 is the utility model discloses the grading wheel structure, fig. 5 is a blade support ring 6 structure. In the figure, 1 is a main framework, 2 is a blade, 3 is a sinking type blade supporting disk, 4 is a blade supporting disk, 5 is a bottom plate, and 6 is a blade supporting ring.

Detailed Description

The specific implementation mode of the utility model is shown in the attached drawings of the specification, and the attached drawings 4 and 5 of the specification are an example of the utility model. The blade support device comprises a main framework 1, blades 2, a blade support ring 6, a blade support plate 4 and a bottom plate 5; the blade supporting ring 6 and the blade supporting disk 4 are respectively sleeved on the main framework 1; the blade 2 is positioned by the main framework 1, the blade supporting disk 4, the blade supporting ring 6 and the circumferentially distributed gap on the bottom plate 5 and is welded with the main framework, the blade supporting disk, the blade supporting ring and the bottom plate into a whole; blade supporting disk 4 cover on the excircle of main frame 1, be located the middle part of main frame 1, the upper and lower end of blade supporting disk 4 have blade support ring 6 respectively, bottom plate 5 covers on the excircle of main frame 1 lower extreme, blade 2 distributes in the breach of the circumference equipartition of blade support ring 6, blade supporting disk 4 and bottom plate 5 to weld into whole with them.

The utility model discloses work flow: the grading wheel is a core component on a grading machine of powder grading equipment, powder particles are graded in thickness by the aid of the rotary grading wheel, and for part of superfine powder, the grading requirement can be met only by the aid of a higher rotating speed, linear speed of the blade 2 is higher at a high rotating speed, corresponding centrifugal force is increased, the blade 2 is easy to bend and deform outwards at a position between blade supporting disks, accordingly, rotation precision of the grading wheel is affected, grading is accurate, and the grading wheel is damaged. In the novel grading wheel structure, the blade supporting ring 6 and the blade supporting disk 4 are arranged accordingly. The blade supporting disk 4 is sleeved on the excircle of the main framework 1 and is positioned in the middle of the main framework 1, blade supporting rings 6 are distributed at the upper end and the lower end of the blade supporting disk, and the number of the blade supporting rings 6 depends on the rotating speed of the grading wheel and the specification of the grading wheel, and is usually 2-6. The rotating speed is high, or the total length of the grading wheel is large, the number of the blade support rings 6 is more, and therefore the blades of the grading wheel cannot be plastically deformed under high-speed rotation.

Through practice verification, the utility model discloses can realize the inside better permeability of classifying wheel, reduce piling up of powder in classifying wheel inside, avoid the influence to classifying wheel operation stationarity, simultaneously, under the condition of guaranteeing mechanical properties, with the material still less, manufacturing is simpler, the cost is reduced. Makes up the defects of the existing grading wheel and can achieve the aim of the invention.
