Embodiment 1

[0034] Such as figure 1 , 2 As shown, the roller press cylinder of the roller press granulator of the present invention comprises cylinder body 1, and the outer surface of cylinder body 1 is provided with granulation tank 11, is provided with elastic portion 12 on the bottom of granulation tank 11, and elastic portion The lower side of 12 has a buffer chamber 13, the buffer chamber 13 communicates with the pressurization chamber 14 and is sealed and isolated from the outside of the cylinder 1, the pressurization of the pressurization chamber 14 can make the elastic part 12 squeeze the granulation tank 11. This structure achieves anti-clogging by extruding the granulation tank 11, and there is no through hole in the granulation tank 11, which effectively prevents the blockage of the through hole in the granulation tank 11. This structure can effectively use the elastic part 12 to push, thereby It is convenient to realize the cleaning of the clogged granulation tank 11, so as t...

Embodiment 2

[0040] Such as image 3 , 4 As shown, the roller press cylinder of the roller press granulator of the present invention comprises cylinder body 1, and the outer surface of cylinder body 1 is provided with granulation tank 11, is provided with elastic portion 12 on the bottom of granulation tank 11, and elastic portion The lower side of 12 has a buffer chamber 13, the buffer chamber 13 communicates with the pressurization chamber 14 and is sealed and isolated from the outside of the cylinder 1, the pressurization of the pressurization chamber 14 can make the elastic part 12 squeeze the granulation tank 11.

[0041] The side walls of the buffer cavity 13 have protrusions, which are used to prevent the opposite side walls of the buffer cavity 13 from sticking. Through holes are provided in gaps between adjacent protrusions, and the buffer chamber 13 communicates with the pressurizing chamber 14 through the through holes.

[0042] The cylinder body 1 is hollow and provided with ...

Embodiment 3

[0044] Based on the rolling cylinder of embodiment 1 or 2, its anti-granulation tank 11 blockage method is:

[0045] Step 1: The granulation tank 11 rotates with the cylinder body 1. After the extrusion and granulation of the granulation tank 11 is completed, the pressurization chamber 14 is gradually pressurized, and the elastic part 12 deforms and squeezes the granulation tank 11. At the same time, the elastic part 12 will produce The unshed material particles in the particle trough 11 are pushed out;

[0046] Step 2: After the material particles are pushed out, the piston 22 is gradually moved away from the granulation tank 11 to reduce the pressure in the booster chamber 14 until the pressure in the booster chamber 14 drops to negative pressure with the rotation of the cylinder 1;

[0047] Step 3: After the pressurized chamber 14 is decompressed, the pressure of the assembly is increased. When the pressure is increased to atmospheric pressure, the granulation tank 11 perfo...

Abstract

The invention relates to the field of rolling granulation, in particular to a rolling barrel for a rolling type granulator. The rolling barrel comprises a barrel body, the outer surface of the barrel body is provided with a granulation groove, the bottom of the granulation groove is provided with an elastic part, the lower side of the elastic part is provided with a buffer cavity, the buffer cavity is communicated with a supercharging cavity and is in sealed isolation from the outside of the barrel body, and the supercharging cavity is supercharged to make the elastic part squeeze the granulation groove. Against problems, the rolling barrel for the rolling type granulator is provided. The rolling barrel for the rolling type granulator is simple in structure, and anti-blockage inside the granulation groove can be performed through control over pressure increase or pressure decrease. Besides, through the design of the anti-blockage structure, the limitation on granulation raw material humidity or viscosity can be reduced, the requirements for granulation raw material powder are lower, and the raw material powder processing cost is reduced. According to the structure, the anti-blockage is achieved by squeezing the granulation groove, the granulation groove is not provided with a through hole, and the blockage of the through hole in the granulation groove is effectively prevented. According to the structure, push and pressure can be performed by effectively utilizing the elastic part, so that the blocked granulation groove is cleared, and an anti-blockage effect is guaranteed.

Description

technical field [0001] The invention relates to the field of rolling granulation, in particular to a rolling cylinder of a rolling granulator. Background technique [0002] Pellet mills can be divided into feed pellet machines and biomass energy pellet machines. Widely used in pharmaceutical, chemical and food industries. It is mainly composed of feeding, stirring, granulating, transmission and lubrication systems. Its working process is to require the compound powder with a water content of not more than 15%, enter the feeding auger from the hopper, adjust the speed of the stepless speed regulating motor to obtain a suitable material flow, and then enter the agitator, and stir it with the steam through the stirring rod. Mix and temper. If you need to add molasses or oil, add it from the mixing drum and steam together. The amount of oil added generally does not exceed 3%, otherwise it will be difficult to form. After conditioning, the temperature of the mixed powder can re...
