Embodiment 1

[0034] like 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 to e...

Embodiment 2

[0040] like 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 a p...

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 chute 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 perfor...

Abstract

The invention relates to the field of roller granulation, in particular to a roller cylinder of a roller granulator. It includes a cylinder body. The outer surface of the cylinder body is provided with a granulating tank. An elastic part is provided on the bottom of the granulating tank. The lower side of the elastic part has a buffer cavity. The buffer cavity is connected to the pressurizing chamber and is sealed and isolated from the outside of the cylinder. Pressurizing the pressure chamber can make the elastic part squeeze the granulation tank. In view of the above existing problems, a roller cylinder of a roller granulator is provided. The structure is simple and can prevent clogging in the granulation tank through the control of raising and lowering the pressure. Moreover, through the design of the anti-clogging structure, it can Reduce the dry humidity or viscosity restrictions of the raw materials for granulation, which has lower requirements on the raw material powder for granulation and reduces the processing cost of the raw material powder. This structure prevents clogging by squeezing the granulating tank, and there is no through hole in the granulating tank, which effectively prevents clogging of the through holes in the granulating tank. This structure can effectively use the elastic part to push, thus facilitating the realization of clogging. Clean the granulation tank to ensure the anti-clogging effect.

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...
