Through the technical scheme, the original cylinder screen with the inclined inner part is replaced by the cone screen with the horizontal axis, so that the cone screen is convenient to mount and maintain, and the bearings at the two ends are horizontally mounted, so that the cone screen is uniformly stressed during high-speed rotation and is not easy to damage.

As the preferable mode, the support member groups are provided with a plurality of groups, and the support member groups are sleeved on the circumference of the centrum sieve at equal intervals.

Through the technical scheme, the arrangement of the support group is helpful for strengthening the stability between the rotating shaft and the cone screen.

As one preferable mode, reinforcing rods are arranged between the rotary column and the support member group, and the included angles between two adjacent reinforcing rods are consistent. One end of the rotary column is connected with an output shaft of the rotating motor through a bearing, the other end of the rotary column is arranged at the other end of the barrel support frame through a bearing, and the rotary column is horizontally arranged.

Through above-mentioned technical scheme, the centrum sieve is more close from the thing discharge hopper on the sieve, and the radius of centrum sieve is bigger, and the ejection of compact of screening is just faster.

As above-mentioned a preferred mode, ejection of compact buffer block and undersize thing discharge gate welding, and ejection of compact buffer block is the heliciform downwards.

Through above-mentioned technical scheme, the decurrent ejection of compact buffer block of spiral can place the object speed that falls too bad and cause self damage.

Compared with the prior art, the utility model has the advantages of: the original cylindrical sieve with the inclined inner part is replaced by the centrum sieve with the horizontal axis, so that the installation and the maintenance are convenient, and the bearings at the two ends are horizontally installed, so that the bearing is uniformly stressed during high-speed rotation and is not easy to damage; the closer the centrum sieve is to the oversize material discharge hopper, the larger the radius of the centrum sieve is, and the faster the screened material is discharged; spiral downward ejection of compact buffer block can place the object speed that falls too bad and cause self damage.

Detailed Description

Referring to the attached drawings, the utility model adopts the following technical scheme that the cylindrical centrum sieve comprises a cylinder support frame, a cylinder and a rotating motor, wherein the cylinder and the rotating motor are arranged on the cylinder support frame, a feeding hopper, an oversize material discharging hopper and an undersize material discharging port are arranged on the cylinder, and the centrum sieve controlled by the rotating motor is arranged in the cylinder; the cone sieve comprises a sieve surface, a rotating column and a support group, wherein one end with a large caliber of the cone sieve faces to the oversize material discharge hopper, the support group comprises an internal part and an external part, and the internal part and the external part clamp the sieve surface and are fixedly connected through bolts; and a discharge buffer block is arranged on the discharge port of the undersize product.

The original cylinder screen with the inclined inner part is replaced by the cone screen with the horizontal axis, so that the installation and the maintenance are convenient, and the bearings at the two ends are horizontally arranged, so that the bearing is uniformly stressed during high-speed rotation and is not easy to damage.

The support member group is provided with a plurality of groups which are sleeved on the circumference of the centrum sieve at equal intervals; the provision of the set of support members helps to enhance the degree of stability between the rotating shaft and the cone screen.
