Abstract
The invention discloses an intermittent closed-loop fluidized drying method. The intermittent closed-loop fluidized drying method includes the steps that feeding is carried out: materials are fed from a closed feeding opening; drying is carried out: after nitrogen charging is carried out, gas inside a device is driven by a circulation fan and then heated by a heater to enter a fluidized drying machine, mass-and-heat transferring biphasic exchanging is carried out in a hopper, then the waste gas enters a second-grade dust remover, fine powder is intercepted again, then the waste gas enters a condenser, mass-and-heat transferring biphasic exchanging is carried out again, then the waste gas returns to the circulation fan, and circulation is achieved; discharging is carried out: an overturning plate inside the fluidized drying machine is opened, a vacuum discharging valve is started, and finished products are sucked away. The intermittent closed-loop fluidized drying method is reasonable in design, the device is of a full-closed structure and is charged with nitrogen, when anaerobic materials or materials containing flammable and combustible solvents are dried, oxygen does not exist in the gas, combustion or oxidation can be avoided, fire breaking accidents or explosion accidents can be accordingly and effectively avoided when the device carries out production, and the intermittent closed-loop fluidized drying method is safe.
Description
Technical field
The present invention relates to a kind of closed circuit fluidized drying method of batch (-type).
Background technology
Boiling drier, is one of the equipment of industry in the solid pharmaceutical preparation technological process of production such as pharmacy, chemical industry, food, and material in process of production loss is serious.Traditional boiling drier is generally to have granulation cylindrical shell, is provided with fluid bed, adhesive atomizer, separator and air circulation system in tower.In the time being dried anaerobism material or containing the material of inflammable and explosive character solvent, in traditional drying machine cylindrical shell, there is oxygen, may burn or be oxidized, just likely make equipment, in the time producing, on fire or explosion accident occur, dangerous.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provide a kind of simple in structure, the closed circuit fluidized drying method of batch (-type) of airtight starvation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of closed circuit fluidized drying method of batch (-type), comprise the boiling drier, secondary ash collector, condenser, circulating fan and the heater that connect by closed pipeline, form circulation line and pipeline inside and be filled with nitrogen, there are following steps:
A. charging, the charging of pulse valve control closed-type feed mouth, working strength is little, and material is not stained with pipeline, and rapidly reinforced;
B. dry, pipeline is filled with nitrogen, and nitrogen flow is 0.3～2.0m
3/ min; Fill after nitrogen, the wind of device interior drives through circulating fan; Enter filter and filter, then heating enters boiling drier through heater, heating-up temperature is 50～120 DEG C; Start agitator, in the hopper of boiling drier, through large-area gas-solid contact, carry out the two-phase exchange of mass-and heat-transfer, take away solvent, leave heat; Mixture is through dust removal filter element filter material subsequently, and waste gas enters secondary ash collector, and fine powder is trapped again; Enter subsequently condenser, again carry out the two-phase exchange of mass-and heat-transfer, take away heat, leave solvent; Return afterwards circulating fan, realize circulation, solvent is recycled to solvent recycling can;
C. discharging, opens the turnover panel of boiling drier inside, starts vacuum outlet valve, and dry finished product is siphoned away from airtight discharging opening.
Further, in described step b, nitrogen flow is 1.1m
3/ min, heating-up temperature is 100 DEG C.
Further, the pipeline between described boiling drier and heater is provided with automatic valve.
Further, agitator is connected with stirring motor, and turnover panel is connected with upset motor.
The invention has the beneficial effects as follows: the present invention is reasonable in design, equipment is totally-enclosed structure, be filled with nitrogen, in the time being dried anaerobism material or containing the material of inflammable and explosive character solvent, making does not have oxygen in gas, cannot burn or be oxidized, just can effectively avoid equipment, in the time producing, on fire or explosion accident occurs, so more safer than conventional equipment.
