Abstract
The utility model relates to a built-in fluidized bed which is provided with a tank body; the tank body is internally provided with an airflow distribution plate; the tank body is divided into an upper layer and a lower layer; the upper tank body layer is a drying chamber which is provided with a material outlet; the lower tank body layer is provided with an air inlet; the built-in fluidized bed is particularly used in a drying tower or a granulating tower; furthermore, the built-in fluidized bed, the drying tower and the granulating tower are integrated into a whole; the fluidized bed is internally provided with a mixing device; the mixing device is designed in such a way that a motor drives a mixing shaft by a speed reducer, and the mixing shaft passes through the airflow distribution plate of the fluidized bed from bottom to top and is fixedly connected with a mixing vane. The built-in fluidized bed can effectively avoid the dead angle phenomenon which is easily generated by general fluidized beds, leads the fluidization to be uniform, generates little dust content when working, can obviously improve the qualified rate of the product, and reduce the consumption of material and energy resource.
Description
Technical field
The utility model relates to a kind of fluidized drying device, relates in particular to a kind of built-in fluid bed that is arranged on granulation tower or drying tower inside.
Background technology
Fluidized bed drying device is upwards to spray flowing gas (being generally air) by the airflow-distribution board that is located at apparatus main body inside the granule materials that supplies in the apparatus main body to be flowed and the formation fluosolids.When air passes the fluidized bed airflow distribution grid, particle contact with flowing gas and drying simultaneously as motion, the dispersion of the water of boiling.Because the temperature and the air quantity of moving air can be regulated accurately, therefore such device has improved the uniformity of mixing of materials and temperature transmission, the drying efficiency height, treat the material gentleness, and this device is bigger than the heat capacity coefficient of other drying equipments, can adapt to the drying of the material of large-scale granularity and proportion.
But, in such fluidized bed type dryer, for handled thing being disperseed and drying, when drying is handled the material that water content is bigger or adhesiveness is strong, the material of can be to some extent supplying with can not disperse fully and condense into the problem of piece, these materials have only the surface to be dried, and can intactly sink to the fluosolids bottom, not only hinder the ejection of flowing gas, also have influence on the formation of fluosolids, therefore, the possibility that causes the goods fluid inequality or produce the dead angle phenomenon is arranged.In order to address this problem, the lump material that is trapped in the fluosolids bottom is moved, but this can consume the more energy on the one hand, if air quantity is excessive on the other hand, just can disperse in the normal granules that fluosolids flows, may have influence on the shaping of particle, dust increases, and makes moving of lump material also limited.
The utility model content
The purpose of this utility model is to provide a kind of the qualification rate of built-in fluid bed processing materials is increased substantially, product is produced the efficient height, the few agitating device of dust content.
The technical scheme that realizes the utility model purpose is: the utlity model has a casing, be provided with airflow-distribution board in the casing, casing is divided into two-layer up and down, last layer box body is a hothouse, be provided with discharging opening, following layer box body is provided with air inlet, described built-in fluid bed is used in particular in drying tower or the granulation tower, and with drying tower or granulation tower structure be one, be provided with an agitating device in the fluid bed, this agitating device is to drive shaft by motor via reducer, and shaft passes airflow-distribution board from bottom to top fixedlys connected with stirring vane.
The shaft that the agitating device of above-mentioned built-in fluid bed is positioned at the airflow-distribution board below is provided with bucker.
The stirring vane of agitating device is a cell structure in the above-mentioned built-in fluid bed.
The utlity model has following characteristics:
(1) the utility model is provided with rabbling mechanism in built-in fluid bed, make its drying or dressing while stirring material, by regulating mixing speed, can make and have only lump material that the surface is dried broken and disperse, even so do not increase intake, material can not be bulk yet and be deposited on the fluosolids bottom, the dead angle phenomenon can not appear promptly, can not hinder flowing gas to spray in addition from gas distribution grid yet, thereby can make the fully dry or bag quilt of material, fluidisation is even, saves material and energy consumption, reduces dust and produces.
(2) the utility model is if cooperate the fluid bed outside drying tower or the granulation tower to use simultaneously, built-in fluid bed can be delivered to external fluid bed by the logical charge tube of discharging opening with shaping and granularity and the satisfactory material particles of humidity and further process processing, dry material particles abundant, that particle diameter is too small and compactness is not enough can be handled once more, thereby it is few to guarantee that product contains Dust Capacity, improve yield rate greatly, granulating efficiency is good.
(3) in the utility model in the agitating device of built-in fluid bed, on the shaft that is positioned at below the fluid bed dividing plate, be provided with bucker, can avoid the equipment such as bearing, motor of below to be etched, prolonged service life of equipment.
(4) stirring vane is designed to the cell structure that stainless pipe is welded in the built-in fluid bed sole device of the present utility model, can under the prerequisite of not destroying the material particles shape, optimize mixing effect on the one hand, make material be difficult for adhering to foliage on the other hand, reasonable in design ingenious.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, down and according to specific embodiment and in conjunction with the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
(embodiment 1)
See Fig. 1, the utlity model has a casing 1, be provided with airflow-distribution board 2 in the casing 1, casing is divided into two-layer up and down, last layer box body is a hothouse 3, be provided with discharging opening 4, following layer box body is provided with air inlet 5, in the present embodiment, this built-in fluid bed is fixed in the drying tower 7, with drying tower 7 structures be one, be provided with an agitating device 6 in the fluid bed, this agitating device 6 is to drive shafts 63 by motor 61 by reductor 62, and the airflow-distribution board 2 that shaft 63 passes fluid bed is from bottom to top fixedlyed connected with the stirring vane 64 of the cell structure that stainless pipe is welded, in agitating device 6, on the shaft 63 that is positioned at below the airflow-distribution board 2, be provided with bucker 65.
When built-in fluid bed of the present utility model is worked, air is sent into built-in fluid bed from air inlet 5, because the blowing of bottom air, make material particles strenuous exercise, the dispersion of airflow-distribution board 2 tops, agitating device 6 starts simultaneously, under stirring vane 64 rotations, material particles contacts with flowing gas and dry, and fluidisation is even, and dry materials is abundant, epigranular, finished product is discharged from discharging opening 4.
