Detailed Description

The following detailed description of embodiments of the utility model refers to the accompanying drawings in which:

as shown in fig. 1 to 3, the split sludge granulator die comprises a ring die body and a plurality of die holes annularly arranged on the ring die body, wherein the ring die body is of a split structure, namely, the ring die body is installed in an assembling mode.

The ring die body comprises an inner ring die 1 and an outer ring die 2 which are coaxially arranged, and the outer ring die 2 is sleeved on the periphery of the inner ring die 1; when the device is installed, the outer ring die 2 is in pin connection with the inner ring die 1, so that the outer ring die 2 and the inner ring die 1 are fixed, and the relative movement of the outer ring die 2 and the inner ring die 1 is prevented.

Specifically, the lower end of the inner ring die 1 extends outwards horizontally to form an epitaxial ring 6, the inner ring die 1 and the epitaxial ring 6 are integrally formed, and the connection combination section of the inner ring die 1 and the epitaxial ring 6 is L-shaped, namely the epitaxial ring 6 protrudes out of the inner ring die 1. The epitaxial ring 6 is coaxially provided with a clamping groove 7.

The outer ring die 2 is arranged on the epitaxial ring 6 and is attached to the inner ring die 1. The lower end of the outer ring die 2 is coaxially provided with a clamping ring 8, and the clamping ring 8 is arranged in the clamping groove 7 in a clamping mode.

When inner ring mould 1 and outer ring mould 2 adopt the pin junction, epitaxial ring 6 with the hoop all is equipped with a plurality of fastening pins 9 between the snap ring 8, and fastening pin 9 wears to establish between epitaxial ring 6 and snap ring 8 promptly, fastening pin 9 and epitaxial ring 6 and 8 tight fits of snap ring are in order fixed.

In this embodiment, the die hole includes a pre-pressing area 3, a forming area 4, and a releasing area 5, which are correspondingly communicated in sequence, the pre-pressing area 3 is a tapered hole, the pre-pressing area 3 is disposed on the inner ring die 1, and the pre-pressing area 3 and the inner ring die 1 are integrally formed. The forming area 4 and the releasing area 5 are combined to form a stepped hole, the forming area 4 and the releasing area 5 are arranged on the outer ring die 2, and the forming area 4, the releasing area 5 and the outer ring die 2 are integrally formed.
