The hole, taper air channel that a kind of novel vertical multilayer cool dryers is used
Technical field:
The hole, taper air channel that a kind of novel vertical multilayer cool dryers is used is applicable to the occasion that chemical industry, food, medicine etc. need dry powdery or granular material.
Background technology
Some chemical industry, food, medicine etc. need the occasion of dry powdery or granular material, dregs of beans cool dryers as the liquefaction industry, in order to save space, usually adopt the vertical multi-layer drier, described vertical multi-layer drier is provided with a plurality of dryings and cooling aspect, and each drying and cooling aspect are provided with the Double-layer clamp central layer; Described Double-layer clamp central layer is provided with two steel plates in up and down, hollow between the steel plate of two of up and down, and namely mezzanine space is established in inside, for delivery of heated drying air or dry cold wind, establishes air ports on the Double-layer clamp central layer, and air ports connects the inner clamps sheaf space; Set two steel plates up and down that have of Double-layer clamp central layer, the upper strata is provided with the cellular aperture of densely covered pillar, by cellular aperture, directly hot-air or cooling-air is sent in the middle of material; Drier is provided with blade agitator and conveyer, make material rapid draing and cooling by the blade material that overturns, and the high temperature dregs of beans of moisture content enters cool dryers from the top, by after heated air drying and dry cold air abundant cooling, after carrying, the conveyer that is provided with by drier enters between finished product-packaging cart; This structure has following shortcoming: due to the upper strata steel plate of Double-layer clamp central layer; because the needs of intensity; general thickness of slab and also increases thickness of slab according to the needs of load all more than 12mm, in order to increase air velocity; make gas have enough flow velocitys to penetrate material; the general aperture of Double-layer clamp central layer upper strata has cellular aperture is smaller, but in the middle of routine use, aperture often can run into the obstruction of molecule dregs of beans; and reduced efficient, often need the labor cleaning could recover normal.
Summary of the invention:
Often can run into the obstruction of small material such as particle dregs of beans for overcoming the existing cellular aperture of vertical multi-layer drier, and reduced efficient, often need the labor cleaning could recover normal problem, the hole, taper air channel that a kind of novel vertical multilayer cool dryers is used is now proposed, its primary structure is as follows: at first, if traditional vertical plate dryer structure: dryer shell, Double-layer clamp central layer, blade agitator, conveyer, establish inlet and outlet on the Double-layer clamp central layer; Then, the cellular aperture of pillar that Double-layer clamp central layer upper strata is had makes the cellular aperture of taper into, the cellular aperture of described taper is when the steel plate machining small of the upper strata of former Double-layer clamp central layer, increased the taper depth chamfering on original aperture basis, the straight hole that has kept certain distance, but enlarged the diameter of import, kept the diameter of original exhaust vent.Make hot-air and cooling-air when the smooth bellmouth, the variation in ventilating duct cross section makes air velocity accelerate, during by surperficial straight hole section, air-flow has higher flow velocity, can take away to be attached near the particle of venthole, make simultaneously air-flow have more penetration power, improved penetration range.
With self-cleaning function, the present invention makes the processing ability certainly of single device improve 30%, has improved output, has reduced energy consumption due to high velocity air.

Wherein: (1) dryer shell, (2) Double-layer clamp central layer, (3) blade agitator, (4) conveyer, (5) air ports, (6) charge door, (7) the cellular aperture of pillar, (8) the cellular aperture of taper, (9) upper strata steel plate, (10) lower floor steel plate.
The specific embodiment:
As shown in accompanying drawing 1,2, be provided with a plurality of dryings and cooling aspect in vertical multi-layer dryer shell (1), each drying and cooling aspect are provided with Double-layer clamp central layer (2); Described Double-layer clamp central layer (2) is provided with upper strata steel plate (9) lower floor's steel plate (10), hollow between the steel plate of two of up and down, be that mezzanine space is established in Double-layer clamp central layer (2) inside, for delivery of heated drying air or dry cold wind, on the Double-layer clamp central layer, (2) establish air ports (5), and air ports (5) connects the inner clamps sheaf space; Two steel plates up and down that Double-layer clamp central layer (2) is provided with, upper strata steel plate (9) is provided with the cellular aperture of densely covered pillar (7), by cellular aperture (7), directly hot-air or cooling-air is sent in the middle of material.
As shown in accompanying drawing 3,4, the present invention makes the cellular aperture of pillar (7) that Double-layer clamp central layer upper strata steel plate (9) has into the cellular aperture of taper (8), the cellular aperture of described taper (8) is when upper strata steel plate (9) machining small of former Double-layer clamp central layer (2), increased the taper depth chamfering on original aperture basis, the straight hole that has kept certain distance, but enlarged the diameter of import, kept the diameter of original exhaust vent.Make hot-air and cooling-air when the smooth bellmouth, the variation in ventilating duct cross section makes air velocity accelerate, during by surperficial straight hole section, air-flow has higher flow velocity, can take away to be attached near the particle of venthole, make simultaneously air-flow have more penetration power, improved penetration range.
