DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings:

[0027] Referring to the accompanying drawings: the continuous automated production line of guanidine acetic acid granules comprises

[0028] The powder forming unit 1 is used to receive the wet material, and dry the received wet material, and then crush the material to form a powder material after the material is dried; and

[0029] The particle forming unit 2 is used to receive the powder material delivered by the powder forming unit 1 and the slurry delivered by the slurry mixing tank 3, to mix the powder material and the slurry at high speed to form a wet soft material, and then to cut the wet soft material into uniform wet particles; and

[0030] The particle shaping unit 4 is used to receive the wet particles delivered by the particle forming unit 2, to make the wet particles into particles with smaller volumes, and then to gradually transform the smaller particles into spherical particles through shaping;

[0031] The drying unit 5 is used to receive the spherical particles delivered by the particle shaping unit 4 and dry the spherical particles;

[0032] The screening unit 6 is used to receive the dried spherical particles delivered by the drying unit 5, to screen the dried spherical particles for quality inspection, and the qualified particles screened out enter the total mixer 7 for final mixing treatment, the coarse particles are sent to the pulverizer 8 for pulverization and re-screening, and the fine particles are recovered to the particle forming unit 2 for re-mixing; and

[0033] The packaging unit 9 is used to receive the particles delivered by the total mixer 7, perform quality inspection on the particles, and package them after completion. The principle of the utility model is to realize automatic granulation through the powder forming unit 1, the particle forming unit 2, the particle shaping unit 4, the drying unit 5, the screening unit 6, and the packaging unit 9, thereby avoiding the tediousness of manual assistance in transporting materials after completing a process, thereby improving production efficiency.

[0034] The powder forming unit 1 includes a plurality of centrifuges 11 and a plurality of V-shaped conveying silos 12. The centrifuges 11 dry the received wet materials, and two of them form a group. Each V-shaped conveying silo 12 corresponds to a group of centrifuges 11, which are used to receive the dried materials conveyed by the centrifuge 11 and crush the received materials into powder materials. The centrifuge 11 is used to dry the moisture in the materials, so that the materials can be obtained after being crushed subsequently. The crushing is achieved by the V-shaped conveying silo 12, that is, it is achieved by using the block breaking blades arranged in the V-shaped conveying silo 12. At the same time, the V-shaped conveying silo 12 is also provided with a propeller blade located below the block breaking blade. The propeller blade is used to transport the powder materials to the discharge port, so that the powder materials are delivered to the particle forming unit 2.

[0035] The particle forming unit 2 includes a plurality of wet granulators 21, which are used to receive the powder material delivered by the corresponding V-shaped conveying silo 12 and the slurry delivered by the slurry mixing tank 3, and after receiving, the powder material and the slurry are mixed at high speed to form a wet soft material, and then the wet soft material is cut into uniform wet particles. The wet granulator is a carrier for material stirring, which fuses the slurry, powder material and other raw materials into a mass, and then uses a cutter to make the mass into a plurality of granular particles.

[0036] The particle shaping unit 4 includes a plurality of distributors 41, a plurality of swing granulators 42, and a plurality of spheronizers 43. The wet particles sent out by the wet granulator 21 fall onto the belt conveyor and are transported to the distributor 41 by the belt conveyor. The distributor 41 evenly distributes the wet particles to each swing granulator 42. The swing granulators 42 are grouped in pairs. The distributor 41 corresponds to two groups of swing granulators 42. After receiving the particles, the swing granulator 42 uses mechanical transmission to make the drum reciprocate to squeeze the material from the screen to form particles with smaller volume. The spheronizer 43 corresponds to a group of swing granulators 42, which is connected to the two swing granulators 42 at the same time through the feeding hopper 431 and also receives the particles sent by the two swing granulators 42 at the same time, and After receiving, the particles will gradually become spherical particles as their drum rotates. The distributor 41 is used to receive the wet particles and evenly distribute them to each swing granulator 42 after receiving. One distributor 41 is paired with four swing granulator 42, so that the quantity in each swing granulator 42 is uniform, and after the swing granulator 42 squeezes the material from the screen to make smaller particles, the particles will enter the spheronizer 43. Each spheronizer 43 is paired with two swing granulator 42, so that the number of particles inside the spheronizer 43 will not be overloaded, and the particles in the drum of the spheronizer 43 have space to move, that is, the particles can collide with each other in the drum when the drum rotates, so as to shape the particles into spherical particles.

[0037] The fluidized bed 51 is equipped with a dust collecting box 511, which is used to collect the powder generated by the fluidized bed 51 during the drying process. The particles entering the fluidized bed 51 come into contact with the hot air above the air distribution plate, and the material particles are suspended in the air flow to form a fluidized state. The particles in the fluidized state are evenly and fully mixed with the hot air, and very strong heat and mass transfer are carried out to remove moisture and achieve drying. The particles are discharged from the discharge port of the fluidized bed 51, and the powder is recovered into the dust collecting box 51-1 to avoid excessive powder accumulation in the fluidized bed 51 and the effect of the lead drying process.

[0038] The screening unit 6 includes a screening machine 61. The particles sent out from the fluidized bed 51 fall onto the belt conveyor and are transported to the screening machine 61 by the belt conveyor. The screening machine 61 screens the particles, and after screening, the qualified particles enter the general mixer 7 for final mixing treatment, the coarse particles are sent to the pulverizing and granulating machine 8 for pulverizing and granulating and re-screening, and the fine particles are recovered into the particle forming unit 2. The screening machine 61 is used to screen the particles so that the qualified particles can be maintained at the required size, and the screened qualified particles will be transported to the general mixer 7. The general mixer 7 mixes the particles so that the particles are evenly mixed. The coarse particles (i.e., the size of particles larger than the qualified particles) will be sent to the pulverizing and granulating machine 8 for pulverizing and granulating and re-screening, that is, the particles are granulated to the size of qualified particles by pulverizing, and the fine particles are recovered into the wet granulator 21, that is, wet granulation is performed again, so as to achieve the effect of reuse.

[0039] The packaging unit 9 includes a temporary storage tank 91, a metal detector 92, and a packaging machine 93. The particles sent out by the total mixer 7 fall onto the belt conveyor and are transported to the temporary storage tank 91 by the belt conveyor. The temporary storage tank 91 transports the particles to the metal detector 92. The metal detector 92 is used to detect metal foreign matter mixed into the particles during the production process, and after quality inspection, the particles without metal foreign matter are transported to the packaging machine 93 for final packaging processing. The temporary storage tank 91 is used to temporarily store the particles, that is, to allow the particles to cool naturally. After natural cooling, the particles will be sent to the metal detector 92 to check whether metal foreign matter is mixed into the particles. The particles without metal foreign matter are transported to the packaging machine 93, and the particles with metal foreign matter are sent to the designated recycling container. The packaging machine 93 is used to package the particles, that is, to put the particles into packaging bags, and the number of particles in each bag is equal.
