Abstract

The utility model relates to a kind of fluid bed nail plate, has plate body; It is characterized in that: the nailhole described plate body offering some annular arrays; Described each nailhole opening direction is all arranged along same circular arc direction.Fluidized plate hole shape in the utility model fluid bed is as nail shape, therefore title nail plate, nailhole is in circumferencial direction perforate, after wind enters fluidising chamber from bottom, form contorted wind, contorted wind drives material also to be formed contorted, and such material is under wind action rotary fluid, fluid bed bed not easily produces dead angle, and goods fluid is even.

Description

Fluid bed nail plate

Technical field

The utility model relates to mechanical equipment technical field, is mainly used in the dry or cooling to loose shape granule materials of the industries such as casting, mining industry, chemical industry, particularly a kind of fluid bed nail plate.

Background technology

Recirculating fluidized bed dry technology is that material to be dried is added fluidized bed body by feeder, preheated air or various boiler waste gas is passed into below bed body, the material particles in fluid bed is made to be blown afloat in fluidized state suspended state, simultaneously in fluid bed upper outlet, by the collected equipment of dried material.Fluid bed bed of the prior art easily produces dead angle, causes goods fluid uneven.

Summary of the invention

The purpose of this utility model overcomes the defect that prior art exists, and provides that a kind of structure is simple, the uniform fluid bed nail plate of fluidisation.

The technical scheme realizing the utility model object is: a kind of fluid bed nail plate, has plate body; It is characterized in that: the nailhole described plate body offering some annular arrays; Described each nailhole opening direction is all arranged along same circular arc direction.

Nailhole described in technique scheme is formed by level board and bending plate cooperation.

Nailhole described in technique scheme is formed by level board and arc plate cooperation.

Level board described in technique scheme and bending plate or arc plate are one overall.

After adopting technique scheme, the utility model has following positive effect:

(1) the fluidized plate hole shape in the utility model fluid bed is as nail shape, therefore title nail plate, nailhole is in circumferencial direction perforate, after wind enters fluidising chamber from bottom, form contorted wind, contorted wind drives material also to be formed contorted, and such material is under wind action rotary fluid, fluid bed bed not easily produces dead angle, and goods fluid is even.

(2) the utility model has the features such as structure is simple, easy to make, consumptive material is few, cost is low.

Detailed description of the invention

(embodiment 1)

See Fig. 1 and Fig. 2, the utility model has plate body 1; Plate body 1 offers the nailhole 2 of some annular arrays; Each nailhole 2 opening direction is all arranged along same circular arc direction.

Nailhole 2 is coordinated by level board 3 and bending plate 4 and is formed.

Level board 3 and bending plate 4 are an entirety.

(embodiment 2)

See Fig. 1 and Fig. 3, the utility model has plate body 1; Plate body 1 offers the nailhole 2 of some annular arrays; Each nailhole 2 opening direction is all arranged along same circular arc direction.

Nailhole 2 is coordinated by level board 3 and arc plate 5 and is formed.

Level board 3 and arc plate 5 are an entirety.

Operation principle of the present utility model is: nailhole 2, in circumferencial direction perforate, after wind enters fluidising chamber from bottom, forms contorted wind, contorted wind drives material also to be formed contorted, such material is rotary fluid under wind action, and fluid bed bed not easily produces dead angle, and goods fluid is even.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
