Abstract

The utility model discloses anti-plug clapboard, including a fan shaped board and an arc screen hole arranged along the circle direction of the fan shaped board. The slanted angle Alpha of the arc screen hole against the side fan shaped board in the direction of the center of a circle on the material feeing would be 55-75 degrees. Beta slanted angle against the side fan shaped board along the direction of the center of a circle on the material discharge would be 50 - 65 degrees. The vertical length of the screen hole in the direction of the vertical fan shaped board would be 1-10mm. The clapboard is simple in design. The materials and the grinding body would not plug the screen holes. The utility model has the advantages of good ventilation, little workload of maintenance and repair.

Description

The anti-clogging partition panel

Technical field

The utility model relates to a kind of ball mill parts, relates to a kind of anti-clogging partition panel that is used for ball mill particularly.

Background technology

The ball mill partition panel is the abrasive material that is used on the ball mill separate between each storehouse, guarantees the isolated part that grinding charge material such as building materials abrasive dust, metal mining powder and cosmetic raw materials abrasive dust etc. pass through.The ball mill partition panel that China is traditional such as Fig. 1, Fig. 2 and shown in Figure 3, this partition panel existing problems: (1) comb hole is in that long (B 〉=20mm), material easily is stuck in flow process perpendicular to the axial length of fanning strip surface direction; (2) charging angle too little (38 °) has created the chance that stops for the coarse granule material; (3), discharging angle too small (45 °), two storehouses originally are small abrasive body on one's body, an irregularly shaped back material is worn in the comb hole and abrasive body in small, broken bits enters in the comb hole and can block.(4) it is shorter that original partition panel is subjected to its comb hole of structural limitations, wasted certain draught area.Therefore partition panel often exists by material and abrasive body clogging in equipment work, and deficiency in draught, grinding machine " full mill ", the problem of sticking with paste ball, has increased the workload of maintenance of equipment, maintenance.

The utility model content

The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, can not produce material and abrasive body and stop up the comb hole, ventilates, maintenance, the anti-clogging partition panel that maintenance workload is little.

For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of anti-clogging partition panel, comprise fan-shaped plate body and the arc sieve aperture that is provided with at fan-shaped plate body circumferencial direction, described sieve bend bore edges is feed side to angle [alpha]=55 that fan-shaped plate body center of circle direction tilts °-75 °, and exit side to angle beta=50 that fan-shaped plate body center of circle direction tilts °-65 °, described sieve aperture is at the axial length L=1-10mm perpendicular to fanning strip surface direction.

Because sieve aperture reduces greatly at the axial length perpendicular to fanning strip surface direction, reduced the current resistance when material passes through the comb hole, prevent that material silts the comb hole up, and owing to the sieve bend bore edges increases to the angle that fan-shaped plate body center of circle direction tilts greatly at feed side and exit side, make that remain near the comb hole material and abrasive body is difficult for retaining during half-turn on ball mill forwards to, thereby played the effect of the hole plug that prevents to comb.Owing to avoided the obstruction in comb hole, can avoid the minimizing of the draught area of partition panel in addition, also make the maintenance of ball mill, maintenance greatly reduce.

Described fan-shaped plate body central angle γ=32.7 ° is provided with two groups of described arc sieve apertures on this fan-shaped plate body, the rib width between two groups of arc sieve apertures is identical with rib width of each group sieve bend bore edges.Central angle with respect to 16.4 ° of former partition panels, central angle of the present utility model has increased by one times, make the quantity of forming the required partition panel of compartment reduce half, and the rib width between two groups of arc sieve apertures is identical with the rib width of sieve bend bore edges, the arc length of each arc sieve aperture is increased, strengthen draught area.

Experiment showed, and adopt structure of the present utility model, solved the problem of equipment common deficiency in draught that exists in running completely, its partition panel comb seam width of raw material grinding of using as manufacture of cement can reduce to 6mm by original 14mm; Its partition panel comb seam width can reduce to the 4mm width by original 6mm during cement grog grinding; Dwindling of partition panel comb seam width dimensions can make by the time of staying prolongation of grinding material in ball mill, by prolonging the mill efficiency that residence time of material can improve equipment, reach the purpose of the specific area of raising equipment unit-hour output and product simultaneously, for industry energy conservation, improve the quality of products and played crucial effects.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As Fig. 4, Fig. 5 and shown in Figure 6, anti-clogging partition panel of the present utility model, comprise fan-shaped plate body 1 and the arc sieve aperture 2 that is provided with at fan-shaped plate body 1 circumferencial direction, described arc sieve aperture 2 edges are feed side 3 to angle [alpha]=55 that fan-shaped plate body 1 center of circle direction tilts °-75 °, and exit side 4 to angle beta=50 that fan-shaped plate body 1 center of circle direction tilts °-65 °, described sieve aperture 2 is at the axial length L=1-10mm perpendicular to fan-shaped plate body 1 surface direction, referring to Fig. 6.In Fig. 4, described fan-shaped plate body 1 central angle γ=32.7 °, identical at rib 5 width that are provided with on this fan-shaped plate body 1 between 2, two groups of arc sieve apertures 2 of two groups of described arc sieve apertures with rib 5 width of each group sieve bend bore edges.The direction of arrow indication is the current direction of material in Fig. 3, Fig. 5, Fig. 6.

With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment the protection domain that all any improvement that the utility model is done or modification all belong to the utility model claim.
