Hammer type shearing granulator

Abstract

A hammer type shearing granulator comprises a granulating cabin (2) provided with a feeding port (1) and a discharging port (11), a blade support (4) and shearing blades (3) installed on the blade support, wherein the blade support (4) is installed in the granulating cabin and can rotate around a horizontal central shaft (5). The outer end of the central shaft of the blade support is connected with a power transmission device. The blade support is of a transversely arranged cylindrical-cage-shaped structure, cylindrical-cage-shaped strips (4a) are evenly distributed on the outer circumferential face of the blade support, each blade is of a structure with a single side or double sides provided with edges, installation holes (3a) capable of being freely sleeved on the cage strips (4a) are arranged at one ends or two ends of the blades, at least two blades are evenly installed on each cage strip, the blades on two adjacent cage strips are arranged in staggered mode, and a screen net (10) is arranged at the position of the discharging port of the granulating cabin. Expansion tobacco stalk granulation is performed by means of the hammer type shearing granulator, particle shape of ternary porous particles of expansion tobacco stalk is changed, production yield is improved, a product filling value is improved, and service life of the blades is prolonged.

Description

technical field [0001] The invention relates to the technical field of granulation of expanded tobacco stems and crushing devices for other stalks. Background technique [0002] Expanded tobacco stem granulation is one of the key processes in the production of expanded tobacco stem ternary porous granules, which has a very important impact on the filling value, product shape and product yield of ternary porous granules. [0003] The traditional granulation equipment has at least the following disadvantages: firstly, due to the limitation of the shape and structure of the blade, when the blade hits the expanded tobacco stem, the expanded tobacco stem will be torn and pulverized, resulting in a relatively large crushed product. The ternary porous particles are particle products that require a certain diameter, and particles and powders with a particle size of less than 1.5mm can only be disposed of as waste, which reduces the production yield of the product. Secondly, due to ...

AI Technical Summary

Problems solved by technology

[0003] The traditional granulation equipment has at least the following deficiencies: First, due to the limitation of the shape and structure of the blade, when the blade hits the expanded tobacco stem, the expanded tobacco stem will be torn and pulverized, and the resulting product will be relatively large

The ternary porous particles are particle products that require a certain diameter. Particles and powders with a particle size of less than 1.5mm can only be disposed of as waste, which reduces the production yield of the product.

Secondly, due to the limitation of the shape and structure of the blade itself and the fixed connection between the blade and the blade holder, the blade also strongly squeezes the expanded tobacco stem when it hits the expanded tobacco stem, causing the expanded tobacco stem to have a strong impact on the impact of the blow. Lower shrinkage, lowering the fill value of ternary porous particles

Thirdly, the blade hits and tears the expanded tobacco stem, the fibers on the fractured surface of the expanded tobacco stem are torn off, the fractured surface of the expanded tobacco stem is irregular, and the shape of the product after granulation is irregular and the grain shape is poor

Fourth, the blade is only quenched, and its wear resistance is relatively poor. If the hardness is too high, the blade is easy to break, and if the hardness is low, it is easy to deform and wear, which reduces the service life of the blade.
