Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

The first embodiment is as follows:

referring to fig. 1-7, a dynamic sieving granulation disc comprises a disc 1 with a basin-shaped structure for granulation, a sieving plate 2 is arranged on the inner wall of the disc 1, the sieving plate 2 is arc-shaped with a hyperbolic structure, the outer arc of the sieving plate 2 is matched and connected with the inner wall of the disc 1, the front end 21 of the sieving plate 2 is far away from the upper edge of the disc wall of the disc 1, the rear end 22 is close to the upper edge of the disc wall of the disc 1, and a sieving hole 23 is arranged on the sieving plate 2. During the use, 1 rotations of disc, the material to in the disc 1 carries out the granulation, and before forming the granule, the material all rotates along 1 bottom of disc, is hung down by the spatula in the ascending section, and at this in-process, along with time's lapse, the granule grow gradually, and under the effect of disc centrifugal force, great granule is located the top of material all the time. Because the sub-sieve plate 2 is provided with the sub-sieve holes 23, and the front end 21 of the sub-sieve plate 2 is closer to the bottom of the disc 1, wherein the front end 21 of the sub-sieve plate 2 faces the rotating direction of the disc 1. Big granule is located the superiors, and rolls around the disc lateral wall, and at rolling in-process, when the granule reaches certain diameter, big granule just enters into and divides on the sieve board 2, when rolling on dividing sieve board 2, does not reach the granule of corresponding diameter and passes through sieve mesh 23 and fall into and continue the granulation in disc 1, and the granule that reaches the diameter rolls out disc 1 from the rear end 22 of dividing sieve board 2 through dividing sieve board 2, collects through conveyer belt or container. Through foretell structure, install the timely screening that divides that the sieve plate 2 can be dynamic at 1 inner wall of disc 1 and go out the granule that has reached required diameter, the granule that does not reach required diameter drops into and continues the granulation shaping in the disc, consequently adopts and divides behind the sieve plate 2, the granule that can be timely separation has reached required diameter to can obtain the granule of size unity. The production is convenient, no additional screening equipment is needed, the occupied space is small, and the labor cost is low.

Because the rotating speed of the disc granulator is relatively low, the requirement can be met by arranging the sub-sieve plate 2 on the inner wall of the disc 1. Of course, two or three screening decks 2 may be provided in order to maintain balance or screening efficiency.

Referring to fig. 2, in a preferred embodiment, the sifting plate 2 is formed in a horn shape, and the front end 21 has a width smaller than that of the rear end 22, so as to scoop upper large particles onto the sifting plate 2 during rotation. The front end 21 may be rounded and smoothed to prevent particle damage during impact.

Further, the sieve holes 23 are waist-shaped circular holes which are distributed in an annular array around the axis of the inner wall of the disc 1. The particles rotate around the side wall of the disc 1 along the same rotating path as the waist circular hole, but the moving direction is opposite, for example, in the normal production process, referring to fig. 1, the disc 1 rotates anticlockwise, the formed particles fall to the bottom of the disc 1 from the right side clockwise after being taken up by the disc 1, and the particles enter the sub-sieve plate 2 when rolling downwards anticlockwise. By adopting the waist circular holes, particles which do not reach the required particle size pass through the screening holes 23 and fall into the disc 1 when rolling downwards clockwise. For the round hole, under the state of slope, the oval hole provides branch sieve time and space for the granule to divide the sieve on dividing sieve plate 2, and the granule that reaches the particle diameter is unlikely to the spring and goes out and divides sieve mesh 23, divides sieve effectual, efficient.

Referring to fig. 3-7, in a preferred embodiment, the screening plates 2 are adjustably or replaceably mounted on the inner wall of the disc 1 for obtaining different particle sizes or different production materials.

Example two:

Through the cooperation of slide 25 and spout 12 to the height that the adjustment divides sieve 2 to be located the disc 1 lateral wall, thereby adapts to different material granulations. The sliding plate 25 can be drawn out from the chute 12, so that the sieve plates 2 with different apertures can be replaced, and the granulation requirements with different particle sizes can be met.

Specifically, the chute 12 is composed of two oppositely arranged inclined plates 11, notches 24 are arranged at corresponding positions of the screening plate 2 and the two inclined plates 11, the sliding plate 25 is clamped in the chute 12 composed of the two inclined plates 11, and the sliding plate 25 is connected and supported with the screening plate 2 through a connecting rod 251. Simple structure and convenient manufacture. And the sloping plate 11 does not extend to the bottom of the disc 1, so that the rotation of the material below is not hindered.

Example three:

referring to fig. 6 and 7, two U-shaped clips 26 are arranged at the edge of the outer circular arc of the sub-sieve plate 2, the U-shaped clips 26 are clipped on the side wall of the disc 1, a second bolt 27 is arranged at one side of the U-shaped clips 26 outside the side wall of the disc 1, and the second bolt 27 and one side of the U-shaped clips 26 outside the side wall of the disc 1 are in threaded fit and abut against the outer side wall of the disc 1. Simple structure, the installation of being convenient for is fit for not installing the granulator later stage installation of dividing sieve 2 and divides sieve 2. The height of the two U-shaped clamps is adjusted through plugging, and the angle and the height of the sub-sieve plate 2 are adjusted. The sub-sieve plate 2 is convenient to replace.

Example four:
