By adopting the drying equipment designed by fluidization principles, the compound heating type drier is applicable to drying, cooling and other operations of powdery, granulate materials in industries such as chemical industry, pharmacy and food.
Description
Technical field
The utility model relates to a kind of drying equipment, particularly a kind of structure of compound heated type drying machine.
Background technology
Fluidized drying has another name called fluidized drying, is the application of fluidization technique in drying.Under fluidized state, heat energy is passed to the material surface that is in direct contact with it in the cross-flow mode by hot-air, carry out direct drying, wet stock is stirred up and down by the effect of flow velocity appropriate thermal air-flow in fluid bed, mix mutually and collision, make the bed of material on the bed surface keep one evenly and can the directed fluidized state that moves, thereby guarantee wet stock and hot-air chamber conducts heat fully, mass transfer, reach the purpose of drying.
Conventional drying machine has Vibratingfluidbeddrier and fixed fluidized bed drying machine, all adopt the form of material and the direct contact heat-exchanging drying of hot-air, running is reliable, and adaptability is strong, is widely used in the drying of the granular material of industries such as food, medicine, chemical industry, light industry.
Drying machine in the prior art has air inlet box body, fluidisation casing and upper cavity three macrostructures from the bottom to top, in the fluidisation casing heat exchanger is arranged, and does not have heating tube, and drying effect is undesirable.
The utility model content
The utility model is set up heating tube in fluid bed dryer, not only produce direct heat transfer in the drying machine, and produces indirect heat exchange.Direct heat transfer in the drying machine is the heat exchange form that wet stock and hot-air adopt the fluidisation attitude.Indirect heat exchange in the drying machine is the heat exchange form that wet stock and hot-air pass through heat exchanger tube.
Air inlet box body, fluidisation casing and upper cavity three parts are arranged from the bottom to top; the right side is provided with hot blast chamber and cold air chamber in the air inlet box body; feed hot blast and cold wind by hot blast import and cold wind import respectively; there is dividing plate to separate between hot blast chamber and cold air chamber; the air inlet box body left bottom has cleanout, is swept into material remaining in the wind box when being used to shut down, and the fluidisation bed board is arranged between fluidisation casing and the air inlet box body; be evenly equipped with the wind hole on the fluidisation bed board, mainly play equal wind and support the material effect.Dryer section and cooling section are arranged respectively in the fluidisation casing from left to right, dry heat exchanger and cooling heat exchanger are arranged respectively in dryer section and the cooling section, dry heat exchanger and cooling heat exchanger are connected with heat exchanger tube respectively, carry out heat exchange with the material in the fluidisation casing, discharge device and the discharge gate that links to each other are arranged at bottom, fluidisation casing right side, be used to control discharge velocity and discharge material, the upper cavity left end side has charging aperture, top to be provided with exhaust outlet.
The utility model is applicable to that industries such as chemical industry, pharmacy, food are to operations such as the drying of powdery, granular material, coolings.
The utlity model has following characteristics:
Fluidization is uniform and stable, does not have dead bed and wears phenomenon with blowing, and can obtain uniform drying, refrigerated product;
Adjustability is good, and thickness of feed layer and the material time of staying in machine can be regulated;
Little to the material table surface damage, can be used for the drying of frangible material;
The operating environment cleaning can be worked continuously, and it is low that the dust of material is carried ratio secretly;
Mode of heating is compound heating, thermal efficiency height, good energy-conserving effect.
Description of drawings
Fig. 1 is that master of the present utility model looks schematic diagram,
Fig. 2 is an A-A cross-sectional schematic of the present utility model.
Fig. 1, among Fig. 2,1 is charging aperture, and 2 is exhaust outlet, and 3 is upper cavity, and 4 is heat exchanger tube, 5 is the fluidisation casing, and 6 is air inlet box body, and 7 is dry heat exchanger, and 8 is cooling heat exchanger, and 9 is discharge device, 10 is discharge gate, and 11 is the cold wind import, and 12 is the hot blast import, and 13 is the fluidisation bed board, and 14 is cleanout.
The specific embodiment
The utility model has air inlet box body 6, fluidisation casing 5 and upper cavity 3 three parts from the bottom to top; the right side is provided with hot blast chamber and cold air chamber in the air inlet box body; feed hot blast and cold wind by hot blast import 12 and cold wind import 11 respectively; there is dividing plate to separate between hot blast chamber and cold air chamber; the air inlet box body left bottom has cleanout 14; be swept into material remaining in the wind box when being used to shut down; fluidisation bed board 13 is arranged between fluidisation casing and the air inlet box body; be evenly equipped with the wind hole on the fluidisation bed board, mainly play equal wind and support the material effect.Dryer section and cooling section are arranged respectively in the fluidisation casing from left to right, dry heat exchanger 7 and cooling heat exchanger 8 are arranged respectively in dryer section and the cooling section, dry heat exchanger and cooling heat exchanger are connected with heat exchanger tube respectively, carry out heat exchange with the material in the fluidisation casing, discharge device 9 and the discharge gate 10 that links to each other are arranged at bottom, fluidisation casing right side, be used to control discharge velocity and discharge material, upper cavity 3 left end side have charging aperture 1, top to be provided with exhaust outlet 2.
During use, wet stock enters in the fluidisation casing from charging aperture 1, the thermotropism wind inlet feeds hot-air simultaneously, the hot blast heating wet stock that fluidisation bed board 13 upwards blows out from the wind hole, material movement enters dryer section, and produce exchange heat with hot blast, feed hot-air in the heat exchanger tube, simultaneously by heat exchanger tube and steam generation exchange heat, water evaporates in the material, along with the carrying out of dry run, moisture constantly descends, and makes material become dry, material movement enters cooling section, the cold wind that blows out by the wind hole on the fluidisation bed board 13 produces exchange heat, simultaneously by heat exchanger tube and cooling water generation exchange heat, is discharged by discharge gate through discharge device after the material cooling.
Hot blast is sent into the air inlet box body of drying machine from the hot blast import, after upwards conducting heat with material by the fluidisation bed board, becomes moisture and upwards discharges from exhaust outlet.The cooling air is sent into the air inlet box body of drying machine from the cold wind import, after upwards conducting heat with material by the fluidisation bed board, discharges from the exhaust outlet at upper cavity top, and exhaust outlet can be connected with deduster.
Steam enters dry heat exchanger, by becoming condensed water after heat exchanger tube and the material heat exchange, discharges from dry heat exchanger delivery port, and cooling water enters cooling heat exchanger, improves by temperature after heat exchanger tube and the material heat exchange, discharges from the cooling heat exchanger outlet.
The utility model is the drying equipment that adopts the design of fluidization principle, is applicable to the operations such as drying, cooling of powdery, the granular material of industries such as chemical industry, pharmacy, food.
