Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
Fluid bed granulator as shown in Fig. 1 to 5, its cylindrical shell comprises air delivery duct 1, fluidized bed granulation room 2 and filter chamber 3, top, air delivery duct 1 arranges fluidized bed granulation room 2, fluidized bed granulation room 2 is made up of the material bin 4 of bottom and the granulation storehouse 5 on top, air delivery duct 1 sidewall connects air inlet 6, installation filter chamber, top, fluidized bed granulation room 23, in filter chamber 3, filter bag is set, filter chamber 3 sidewall connects air outlet 9, air outlet 9 connecting fan 10, the sidewall in the granulation storehouse 5 of fluidized bed granulation room 2 is provided with gun 11, gun 11 is equipped with and the spray gun 12 being granulated storehouse 5 diameter and being in tilted layout at an angle, the shower nozzle of spray gun 12 is towards in granulation storehouse 5, mounting heater 7 on air inlet 6, air inlet 6 front end is provided with filter 8, between the material bin 4 of air delivery duct 1 and fluidized bed granulation room 2, airflow-distribution board 13 is installed, airflow-distribution board 13 has pilot hole 14 along diameter to tangent line, pilot hole 14 radially tangent line and horizontal plane is arranged, the incline direction of spray gun 12 and pilot hole 14 is contrary.
In the present embodiment, gun 11 has 2-6.The axial line of spray gun 12 and diffuser casing diameter angle are 20 ° ~ 60 °.
In order to improve the efficiency of heating surface of heater 7, heater 7 is made up of heat exchanger tube, heat exchanger tube is sleeved on the pipeline of air inlet 6, the pipeline periphery of the air inlet 6 in heat exchanger tube arranges several ring pipe 20, ring pipe 20 upper and lower connects the arm of an isocon 19 respectively, the house steward of two isocons 19 connects steam inlet and steam (vapor) outlet respectively, the high-temperature steam entered in heater 7 can uniformly and pipeline contact, reach the object of evenly fully heat exchange, thus reduce steam use amount, require low to the bearing capacity of equipment, economize energy, reduce production cost.
