A kind of hollow blade drying machine, its structure comprise drying machine housing, hollow shaft, the steam inlet that is positioned at the hollow shaft two ends and condensation-water drain, be positioned at drying machine housing top material charge door and hot carrier gas outlet, be positioned at the hollow blade on the hollow shaft and be positioned at the discharging opening of drying machine housing downside; It is characterized in that the drying machine housing inner bottom part in the hollow blade bottom is provided with the horizontal gas distribution pipe of a band fumarole.
A kind of hollow blade drying machine of the present utility model is characterized in that the parallel two ends with hollow shaft of described horizontal gas distribution pipe are fixed on the drying machine housing sidewall, and its gas distribution pipe bottom is provided with air inlet pipe, and air inlet pipe is passed the drying machine bottom shell.
A kind of hollow blade drying machine of the present utility model is characterized in that described horizontal gas distribution pipe is divided into three sections by the dividing plate of two block gaps; Every section correspondence is provided with an air inlet pipe.
A kind of hollow blade drying machine of the present utility model is characterized in that the described horizontal gas distribution pipe that is divided into three sections, near the gas distribution pipe segment length of drying machine material charge door end be the total pipe range of gas distribution pipe 1/4 be preheating pipeline section district; Middle pipeline section pipe range is 1/2 of total pipe range, is evaporation pipeline section district; End tube section is not long for 1/4 of total pipe range, is dry pipeline section.
A kind of hollow blade drying machine of the present utility model, the fumarole aperture, preheating pipeline section district that it is characterized in that described horizontal gas distribution pipe is less than evaporation fumarole aperture, pipeline section district, and pore is intensive; The pore in dry pipeline section district is less than evaporation fumarole aperture, pipeline section district, but pore is sparse.
A kind of hollow blade drying machine of the present utility model, under the prerequisite of not destroying hollow paddle drying machine agent structure, in the hollow blade bottom distribution device in gas-fluid is set, make heat-carrying gas from bottom to top evenly pass material through distribution device in zones of different, and make fluidization of material by pressure control, increase its fluid ability, the principle of fluid bed is applied on the hollow blade drying machine, so not only increased the fluid ability of material, increased the contact area of material and equipment, also guarantee the moisture degree of unsaturation of device interior each several part, increased the evaporation rate of moisture in the material, improved the drying capacity of drying machine.

The specific embodiment
A kind of hollow blade drying machine, its structure comprise drying machine housing 1, hollow shaft 2, be positioned at the steam inlet 3 and the condensation-water drain 4 at hollow shaft two ends, be positioned at drying machine housing top material charge door 5 and hot carrier gas outlet 6, be positioned at the hollow blade 7 on the hollow shaft and be positioned at the discharging opening 8 of drying machine housing downside; Drying machine housing inner bottom part in the hollow blade bottom is provided with the horizontal gas distribution pipe 9 of a band fumarole.
A kind of hollow blade drying machine of the present utility model, the parallel two ends with hollow shaft of described horizontal gas distribution pipe are fixed on the drying machine housing sidewall, and its gas distribution pipe bottom is provided with steam inlet pipe 10, and air inlet pipe is passed the drying machine bottom shell.
A kind of hollow blade drying machine of the present utility model, described horizontal gas distribution pipe is divided into three sections by the dividing plate 11 of two block gaps; Every section correspondence is provided with an air inlet pipe.
Drying machine of the present utility model, original hollow blade drying machine is divided into three zones---preheating zone, evaporating area, dry section, characteristic according to material, the pore of different porosities is set in zones of different, and control by pressure, guarantee the fluidization of each regional material and the moisture degree of unsaturation that each is regional, to increase the evaporation efficiency of drying machine.
Advantage of the present invention: (1) hot carrier gas is passed in material, makes fluidization of material, has increased the contact area of material and drying machine and the flowability of material, has improved the drying capacity of drying machine; (2) provide the hot carrier gas of different amounts according to the drying machine zones of different to the difference of hot carrier gas demand, guarantee the moisture degree of unsaturation that each is regional, improved the evaporation rate of drying machine.
Material is entered by charging aperture, at first enters the preheating zone gas distribution section of about 1/4 length of its front end, and because of this regional material moisture height, material viscosity is big, opens small-bore and intensive hole, and guarantees the high pressure of hot carrier gas, keeps the flowability of material; Middle about 1/2 length is evaporating area gas distribution section, and this regional moisture evaporates in a large number, needs a large amount of hot carrier gas that steam is taken out of outside the machine, therefore in this regional wide-bore footpath and intensive hole, to guarantee the flow of hot carrier gas; Terminal about 1/4 length is dry section gas distribution section, and water content greatly reduces in this regional material, only needs with the regular hour moisture to be overflowed and get final product from material, and need of production just can be satisfied in little sparse hole, perforate footpath. The size in distribution device and hole is determined by material characteristic and water content. This device is positioned at the hollow blade dryer bottom, makes simply, and is easy for installation, can guarantee the degree of unsaturation that each is regional, can increase by about 20% evaporation efficiency.
During operation, material is added by charge door, after the preheating of preheating zone, arrives evaporating area most moisture are evaporated away, again after the drying district drying, outside discharging opening discharge machine; Steam enters hollow shaft and hollow blade by steam inlet, and for material intensification, evaporation, drying provide heat, condensed water is by outside the condensation-water drain discharge machine; The hot carrier gas of different pressures enters respectively in the distribution device in gas-fluid by carrier gas inlet, come out the hole from the distribution device in gas-fluid tube wall directly to contact with material, and pass material and enter the material sky, the flowability of material and the contact area of material and drying machine have been increased, increased evaporation efficiency, hot carrier gas is exported outside the discharge machine by hot carrier gas with the water vapour that volatilizees from material.
