Problems solved by technology

Sometimes it will directly enter the granulation system in the form of a thin paste. Such a thin paste material will flow directly to the bottom without contacting the heat exchange surface in the gap between the two rolling drums of the granulator and cause blockage, which will seriously affect functioning normally, and the cleanup is very heavy

Embodiment 1

[0058] The present invention is a new type of granulation equipment combined on the basis of a rolling mill with a reticular spiral groove (or a single radial tooth groove) of the drum. When the drum of the rolling mill rotates in the forward and reverse directions, the material placed on the edge of the tooth surface is torn by the differential mesh alveolar, which can tear the lumpy and cake-shaped materials into small particles; When the material is soft (such as pulp, paste, paste) material, due to the gravity and the friction force of the local tooth top, it will be pulled into the axial groove of the drum with the rotation of the teeth and continue to move downward. Until it enters the engagement groove and naturally forms strips or particles. According to different materials, the diameter of the drum can be reasonably designed to meet the balance of the vector sum of the suction friction force and the strip forming force, so that the strip or particle forming force is m...

Abstract

A combined granulator, comprising a multilayer combined box body (11), a temporary feed storage bin (01), and multiple layers and groups of rolling mills. Each group of rolling mills is provided with a rotary joint (04), a cleaning blade (05), an elastic stripping frame (14), a material baffle (07), and a guide plate. The box body is further provided with a waste gas evacuation port (03), and a support is provided with an air inlet (12) at the lowest layer of the granulator. The tooth surface linear velocity and the volumetric flow rate of a rotating drum of each rolling mill (08) at the second layer are higher than those of a rotating drum of each rolling mill (02) at the first layer; the ratios of the tooth surface linear velocities and the volumetric flow rates of the rotating drums having meshed tooth slots or individual radial tooth slots of adjacent rolling mills at the lower layer can be adjusted according to the volume of materials in the region. The granulator can not only strip hard foreign matters, but also simply granulate a soft material, such as cream, paste, and slurry. In addition, the granulator can also directly pull caky and blocky materials into monomer granules, so that soft and hard materials can simultaneously enter the granulator, and granules at an outlet are porous and irregular in shape.

Description

technical field [0001] The present invention mainly belongs to the principle of wet material granulation and equipment combination process, especially relates to a combined granulator using a mesh tooth surface rolling machine for heating as a unit. The combined granulator can be used for high-humidity materials, slurry , paste, paste, cake, block materials, especially suitable for granulation and drying of the above-mentioned mixed materials; used in environmental protection, metallurgy, light industry, chemical industry, food, medicine, feed, agriculture (forestry, animal husbandry, In the fields of fishery product processing and other fields, the paste, paste, slurry, cake, bar, and block materials with higher water content are granulated and dried (dried). The combined granulator of the present invention can also Municipal and industrial sludge are granulated and obtained desiccation (drying). Background technique [0002] With the continuous emergence of new materials ...
