Description

The drying integrated unit of humidification granulating

The utility model relates to the drying integrated unit of a kind of ceramic compression moulding pellet dry preparation process system's usefulness humidification granulating.

In order to make the very thin ceramic powder of grinding can on stamping machine, be pressed into the product base substrate, the water yield of moisture content in the time of just must adding greater than shaping to it, make the moisture content that is dried to forming requirements behind the false particle again, the device structure of making this false particulate material in the prior art has:

(1) horizontal shaft type tablets press (as accompanying drawing 3) flow bed dryer structure.After the water of fine powder material and atomizing just mixes in vertical humidification is dirty, fall into and have transverse axis and its and be provided with the homogenizer of blade, under the blade effect of high speed rotating, material water mixes fully, evenly also forms false particle looser, that the surface is crude again, and false particle falls the excessive moisture drying through fluidized bed dryer again.The equipment of this structure, the humidification homo-effect of fine powder material is better.But have following deficiency: one, false particle surface before dry is more crude, is subjected to bigger the washing away of hot gas flow in the drying process again, thereby is have more tiny powder to exist in the moulding pellet after dry, make molding effect relatively poor, be difficult to adapt to the moulding of high-level efficiency mouldenpress; Two, because all or part of flow velocity of air-flow that utilizes of drying process makes pellet be in suspended state,, generally to after high-efficiency dust remover or two-stage dedusting, could discharge, so current consumption is higher so contain very high dust in the tail gas behind the drying device; Three, because of the humidification homogenizing with dry successively by two separately separate equipment finish, thereby need set up middle transition equipment, cost of equipment is high and floor space is big.

(2) rotation drum type tablets press (as accompanying drawing 4) flow bed dryer structure.Fine powder material infeeds top, humidification homogenizing chamber by the worm conveyor level, water infeeds from center, humidification homogenizing chamber, material mixes and homogenizing under the water dumping bulk cargo dish effect of the high speed rotating of center, chamber setting with water, form the crude and in irregular shape false particle in surface, false particle is piled up along with increasing in humidification homogenizing chamber and is entered into revolving drum, after process is shunted, is collaborated, rolls, brings together in revolving drum, false particle surface is polished, shape also is tending towards ball-type, enters fluidized bed dryer again the excessive moisture drying is fallen.The equipment of this structure, smooth and the shape of the false particle surface of making is near ball-type, help the mouldenpress moulding behind the sub-sieve, but following deficiency is arranged: one, because water dumping bulk cargo dish can't scatter material and the water uniform mixing well, in the material after the granulation clod and not humidification fine powder summation account for more than 25% of material amount, need could to use behind the classification sub-sieve, granulation efficiency is low; Two, because the pellet behind the humidification falls within the bottom in immobilized humidification homogenizing chamber, can not very successfully enter in the revolving drum, so frequent forming device stops up; Three, also there is two, three of the middle deficiency of prior art ().

At the problems referred to above, the purpose of this utility model is to provide seldom clod and not humidification fine powder in a kind of pellet, false particle balling preparation shape, smooth surface can adapt to the moulding of high-level efficiency mouldenpress, and dry back tail gas dustiness is low, be convenient to adopt general purification style discharging, equipment manufacturing cost is low, and floor space is little, humidification city grain that power consumption is economized and the dry drying integrated unit of finishing in a machine of humidification granulating.
