Description
本发明具体涉及一种可实现CIP清洗的干燥制粒机。The invention specifically relates to a dry granulator capable of CIP cleaning.
目前，在制药、食品、化工、冶金等领域，均会使用到流化制设备、流化包衣或者气力输送装置，流化床制粒一般指顶喷流化床，其主要结构包括容器、空气分流板、喷嘴、过滤袋、空气进出口和物料排出口，流化床制粒机使用时，压缩空气和粘合剂溶液按一定的比例由喷嘴雾化，并喷至流化床层上正处于流化状态的物料粉末上，液滴使接触到的粉末润湿并聚结在其周围形成粒子核，同时，由继续喷入的液滴落在粒子核表面上，产生粘合架桥作用，使粒子核与粒子核之间，粒子核与粒子之间相互结合，逐渐形成较大的颗粒，待其干燥后，粉末间的液体桥变成固体桥，即可得到外形圆整的多孔颗粒，由于流化床制粒的全过程不受外力的作用，仅受床内气流的影响，故制得的颗粒具有密度小，粒子强度低，颗粒的粒度均匀，流动性好，压缩成形性好等优点。At present, in the fields of pharmacy, food, chemical industry, metallurgy, etc., fluidized equipment, fluidized coating or pneumatic conveying devices are used. Fluidized bed granulation generally refers to top spray fluidized bed. Its main structure includes containers, Air splitter, nozzle, filter bag, air inlet and outlet and material outlet, when using fluidized bed granulator, compressed air and binder solution are atomized by the nozzle at a certain ratio and sprayed onto the fluidized bed layer On the material powder that is in a fluidized state, the droplets wet the contacted powder and coalesce around to form a particle core. At the same time, the droplets that continue to be sprayed fall on the surface of the particle core, resulting in a bonding bridge The effect is to make the particle core and the particle core, the particle core and the particle combine with each other, and gradually form larger particles. After drying, the liquid bridge between the powder becomes a solid bridge, and a round and porous shape can be obtained Particles, because the whole process of fluidized bed granulation is not affected by external forces and is only affected by the air flow in the bed, so the prepared particles have low density, low particle strength, uniform particle size, good fluidity, and compression formability Good and other advantages.
在现有技术中，流化制设备、流化包衣或者气力输送装置在排风的过程中，对排风进行处理时，均需要使用过滤器。制粒机、包衣机和气力输送机在使用过程中，排风时，大量的粉尘会被拦截在过滤器的表面，随着粉尘的拦截，过滤器阻力会逐渐的增大，随着过滤器的阻力增大，过滤器的通风量会逐渐下降，进而影响了流化床的流化态或气力输送装置的输送量，从而影响了干燥、包衣和输送的效果。为了降低过滤的阻力，流化床、包衣机和气力输送装置在使用的过程中，均会对过滤器进行除尘处理。In the prior art, fluidizing equipment, fluidized coating, or pneumatic conveying devices are all required to use a filter when exhaust air is processed during exhaust air. During the use of granulators, coating machines and pneumatic conveyors, when exhausting, a large amount of dust will be intercepted on the surface of the filter. With the interception of dust, the resistance of the filter will gradually increase. As the resistance of the filter increases, the ventilation of the filter will gradually decrease, which in turn affects the fluidized state of the fluidized bed or the delivery volume of the pneumatic conveying device, thus affecting the drying, coating and conveying effects. In order to reduce the resistance of filtration, the fluidized bed, coating machine and pneumatic conveying device will all perform dust removal treatment on the filter during use.
然而这只能对过滤器进行除尘，而堆积在缸体内的粉尘依旧会使得过滤器的阻力逐渐增大，而要彻底降低该阻力，只能对过滤器进行拆卸并进行清洗，而目前的制粒机只能进行拆卸清洗，而无法实现在线清洗。However, this can only remove dust from the filter, and the dust accumulated in the cylinder will still gradually increase the resistance of the filter. To completely reduce the resistance, the filter can only be disassembled and cleaned. The granulator can only be disassembled and cleaned, but cannot be cleaned online.
