Abstract

The utility model relates to a fluid drying machine with multi-layer vibration, which belongs to a vibration type airflow drying device. The utility model is suitable for the drying process for various grainy materials, flaky materials, strip-shaped materials, etc., and the shape and the quality of the materials after dried both are not changed. The utility model is characterized in that a multiple-hole plate bed (14) of which the layers can be many and can also be less are arranged in a machine body (12); hole plates with different hole diameters can be replaced. Hot wind redistribution pipes (7) of which the number is form 3 to 5 are arranged in the middle of each layer. The utility model has the advantages of reasonable structure and energy saving.

Description

Fluid drying machine with multi-layer vibration

This machine belongs to a kind of oscillatory type fluidization drying apparatus, be applicable to dry before and after the drying of materials such as the powder shape that all do not change of shape and quality, sheet grain, strip.

At present the domestic individual layer straight-line oscillation fluid bed that has used is because its single layer structure causes to yield poorly, and consumption of heat energy is big, and vibrationproof facility imperfection and noise is very big.

The purpose of this utility model provides a kind of multilayer vibration fluidizing drier, and its feature is that the amount doesn't matter porous plate bed (14) of the number of plies is housed in body (12), and can select to change the orifice plate in different apertures; 3-5 hot blast reallocation pipe (7) all is installed in each layer centre.

Details are as follows with its primary structure characteristics and operation principle below in conjunction with accompanying drawing:

Accompanying drawing 1 is the sketch of multilayer vibration fluidizing drier.

By accompanying drawing 1 as can be seen, material is continuously entered respectively on interior each layer porous plate bed (14) of body (12) by vibratory feed unit (1), and under the exciting effect of vibrating motor (8), material is along material bed (14), and great-jump-forward travels forward continuously.Already heated hot-air is entered in the drying machine by hot-wind inlet (6), passes porous plate (4) through each layer hot blast reallocation pipe (7) and contacts with material, carries out sufficient heat exchange, and humid air is discharged by the outlet of the moisture above the loam cake (3) (2).Sight glass (13) can be observed material movement and drying regime in the machine at any time.When dry good material is reduced to body (12) bottom, can by entering after the cold air of cold-air vent (4) discharge is air-cooled, collect discharge from products export (9) by cool air inlet (5).

The main feature of this device is: applied widely, and the output height, energy savings, noise is little.The number of porous plate bed is the amount doesn't matter, and the angle of inclination of each orifice plate all can be adjusted according to kind, granularity, the different of dry required time of material with vibration amplitude, and can select to change the porous plate in different apertures, so this machine scope of application is extremely wide.On each layer porous plate bed, all have additional a plurality of hot blast reallocation pipes (7), hot blast repeatedly contacts with material and multilayer material bed is worked simultaneously, can make full use of heat energy, it is nearly 50% to make it energy savings, and quantity-produced output increases 2-3 doubly than the lamina drying machine.Owing on base (10), adopted rubber spring isolation mounting (11), make the whole machine body vibration steadily, noise is little.

This equipment is applicable to that water content is below 60%, allowable temperature is in the drying of the material of multiple shapes such as 0 ℃-300 ℃ powder shape, sheet, strip, for example: use this machine dried particles shape citric acid material, water content 25% before dry, the output of working continuously 1000kg-2000kg/b, water content 8-5% after dry can reach 0.5% to some material.

This machine is widely used for dry medicine, chemical materials, construction material, grain, feed, vinasse; Various food as: granulated sugar, salt, monosodium glutamate and some agricultural-products, marine product are the more satisfactory drying equipments of every profession and trade.

Claims

A kind of multilayer vibration fluidizing drier belongs to the oscillatory type pneumatic conveying dryer, includes vibratory feed unit (1), vibrating motor (8), body (12), base (10) and porous plate bed (14), it is characterized in that:

A) the amount doesn't matter porous plate bed (14) of the number of plies is housed in body (12), and can selects to change the orifice plate in different apertures;
