Abstract

The utility model provides a vibration drier for the granule materials, comprising a main body, a vibrating motor and a base. The sieve plates in the main body are spirally arranged between an inner cylinder and an outer cylinder. The drying medium between each sieve plate layer adopts the multi-hole entering mode and the multi-hole expelling mode. The utility model has the advantages of favorable drying effect, less impact load of the sieve plates, long service life, homogeneous materials moving, uneasy to clog at the feed inlet, stable operation, etc.

Description

Sleeve-type spiral vibration drier

The utility model belongs to a kind of drying equipment of granular material.

In the production process of chemical industry, food, medicine and other fields, to carry out drying to the bigger particle of water content and handle, to satisfy the requirement of product quality and purposes.Aspect existing drying equipment, it is CN85201427 " multilayer vibrating desiccator in horizontal circle movement " that applicant had once proposed the patent No..This patent folds the composition main body with multilayer ring-type sieve plate is set between urceolus and the inner core, and vibrating motor is equipped with in its underpart, is supported on the base with the spring handle main body; Under the exciting force of vibrating motor, material is moved to lower floor from the upper strata along horizontal ring-type sieve plate, hot blast upwards passes sieve plate successively from the bottom, sees through each layer drying materials.The existing weak point of this patent is that sieve plate is fixed in makes it to be cantilever position on the inner core, material is dropped at lower floor's sieve plate by the upper strata sieve plate in addition, thereby sieve plate not only is subjected to shock loading, and the fixedly part load concentration between sieve plate and inner core, is prone to phenomenon of rupture.In addition, the direction of motion of material and drying medium (hot blast) is not ideal enough, by the carrying a wet drying medium and will certainly increase moisture content to the upper strata of lower floor, thereby makes the drying effect of last layer not ideal enough, and material is bonded near the charging aperture.

In view of the existing deficiency of above-mentioned drying equipment, the utility model provides a kind of drying effect good, rational in infrastructure novel dried device.

Telescopic spiral vibrating drying machine provided by the utility model, comprise main body, base, vibrating motor composition, spring evenly is set between main body and the base, vibrating motor is arranged on the iron plate under the main body chassis, the top of main body is provided with charging aperture, air inlet and exhaust outlet, on the sidewall of main body bottom discharging opening is set.Be characterized in that main body is made up of inner core, urceolus, shell, chassis and sieve plate, inner core, urceolus and shell are arranged on the chassis, the formula sieve plate is arranged between inner core and the urceolus in the shape of a spiral, the inboard of sieve plate is fixed on the outer wall of inner core, the outside of sieve plate evenly is provided with the plurality of rows column, inner core runs through air inlet, and on the inner core between the sieve plate layer air admission hole is set, and on the urceolus between the sieve plate layer steam vent is set.On same level, charging aperture does not run through urceolus for air admission hole and steam vent, and exhaust outlet runs through the space that forms between urceolus and shell, is further described below in conjunction with accompanying drawing.

The telescopic spiral vibrating drier structure schematic diagram that Fig. 1 provides for the utility model;

The telescopic spiral vibrating drying machine that Fig. 2 provides for the utility model, inner core launches schematic diagram;

The telescopic spiral vibrating drying machine that Fig. 3 provides for the utility model, urceolus launches schematic diagram.

According to shown in Figure 1, main body of the present utility model is arranged on the chassis (7) by inner core (2), spiral sieve plate (3), urceolus (12) and shell (4) and forms, vibrating motor (9) is arranged on the iron plate (6) that directly links to each other with chassis (7), evenly arranges spring (8) between base (10) and chassis (7).Consider factors such as wire spring ruptures easily, service life is short, spring (8) adopts rubber spring, makes main body work more steady.Inner tank theca is fixed in spiral sieve plate (3) inboard, the plurality of rows column is evenly arranged in the sieve plate outside, fix place's load to alleviate the sieve plate inboard, every row's column can reach the chassis between the adjacent sieve plate layer and play the short column of sieve plate interlayer to form most by being arranged on.The top of shell (4) is provided with charging aperture (1), air inlet (15) and exhaust outlet (14), make charging aperture run through urceolus, the location arrangements of charging aperture is at the top of sieve plate, and air inlet runs through inner core, and exhaust outlet runs through the annular space that forms between urceolus and shell.Discharging opening (11) is arranged on the sidewall of outer casing underpart, and the position of discharging opening is arranged on the end of sieve plate layer sieve plate, so that material is discharged smoothly.Air admission hole (5) and steam vent (13) are set respectively on inner core between the sieve plate layer and the urceolus, and air admission hole and the steam vent arranged between each sieve plate layer stagger as far as possible, make both not at grade.

According to shown in Figure 2,2～3 air admission holes are set between every sieve plate layer, consider that the moisture content of upper materials will from top to bottom reduce the air admission hole area A i between every sieve plate layer, i.e. A more than the moisture content of lower floor's material gradually ₁＞A ₂＞A ₃＞A ₄In like manner, according to shown in Figure 3, the steam vent area B i of every sieve plate interlayer setting from top to bottom reduces gradually, that is B ₁＞B ₂＞B ₃＞B ₄Two clean-out hatch will be set on the sidewall of urceolus and shell.Material by charging aperture evenly moves downward at the exciting force lower edge of vibrating motor spiral compass screen surface like this, is discharged by discharging opening.After the hot blast that each air admission hole is come in is handled the moisture drying of material through the sieve plate of last layer, most of steam vent discharge of carrying damp and hot wind through the upper strata, and year wet drying medium that each steam vent is discharged is extracted out by exhaust outlet.As A ₃The hot gas of coming in.The overwhelming majority is by B ₃Discharge.Avoided lower floor to carry damp-heat like this, made the dry materials effect on the whole sieve plate better through the dry material of handling of last layer.

The utility model has fully, effectively utilizes drying medium so that the drying effect of material is good, and sieve plate is suffered according to the sleeve-type spiral vibration drier that above-mentioned structure provides Shock loading is little, and material movement is even, and charging aperture and discharging opening are difficult for the advantages such as obstruction. In addition, the advantages such as whole device long service life, main body stable working. The utility model can be widely used in the drying of the field graininess materials such as chemical industry, food, medicine, plastics, metallurgy to be processed.
