As shown in fig. 1 to fig. 3, the embodiment of the utility model provides a distributing plate for fluidized bed, it includes distributing plate body 1, as shown in fig. 3, the last distribution of distributing plate body 1 have a plurality of with the axis of distributing plate body 1 is the trompil 2 that the slope set up, specifically, trompil 2 is in from inside to outside from the up-dip down on distributing plate body 1. Therefore, when wind blows from the bottom to the top of the distribution plate body 1, the direction of the wind changes after the wind passes through the distribution plate, the wind rotates spirally along the inclined direction of the opening and enters a material bin above the distribution plate, and the material in the material bin is fully rotated and boiled; through 2 slope settings of trompil, can compare in seting up vertical hole to 1 make full use of distribution plate body on the distribution plate of same area, can realize that trompil 2 is rateed highly to no dead angle reaches the abundant dry purpose of material.
The embodiment of the utility model provides an in, every trompil 2 with the axis contained angle of distribution plate body 1 is 30 ~ 55 degrees, and the contained angle is preferably 45 degrees, can make wind blow in the material storehouse with the optimal angle with upwards being the form of dispersing from the bottom through setting up of this angle for the material is fully rotatory and dry.
The embodiment of the utility model provides an in, in order to avoid the material to block up trompil 2, every the shape of trompil 2 is in distribution plate body 1 is rectangular shape on the surface, and rectangular shape hole is difficult to by the material jam, is more difficult to the hourglass material moreover.
The embodiment of the utility model provides an in, the width of trompil 2 is 0.2 ~ 0.4 millimeter, the length of trompil 2 is 70 ~ 110 millimeters, as shown in fig. 1, the trompil 2 that sets up from this is the slit form on distributing plate body 1, is more difficult to the hourglass material, because trompil 2 is more dense, trompil 2 seen in fig. 1 is a line, this is only a schematic diagram nevertheless, and trompil 2 is gapped in fact, and only the gap is very little, and graininess material can not block up trompil 2, has great space air inlet moreover.
The embodiment of the utility model provides an in, as shown in figure 1, the cross-section of distributing plate body 1 perpendicular to its axis is circular, and is a plurality of trompil 2 is followed radially being of distributing plate body 1 is dispersed the form and arranges, and arranges every radial distribution of trompil 2 has a plurality of intervals to set up trompil 2, with make full use of space on the distributing plate body 1 sets up more trompils 2 as far as possible to guarantee enough big intake and avoid producing the dead angle.
In the embodiment of the utility model, specifically, each radial gap between the trompil 2 of arranging of distribution plate body 1 and adjacent radial gap between the trompil 2 stagger the distribution, thereby avoid a plurality of clearances to gather together and form great clearance, also can make the air inlet more even like this, form the dead angle easily in great clearance department, through stagger the distribution with each small clearance, avoided the formation in great clearance, thereby avoid forming the dead angle in the material storehouse, and lead to the blind spot district material not to be enough rotatory; therefore, the strength of the distribution plate can be ensured, and the uniform arrangement of the holes is facilitated.
The embodiment of the utility model provides an in, be close to distribution plate body 1's axle center department, trompil 2 is from the distance one section distance department in distribution plate body 1's axle center begins to arrange, and this distance can be for 150 ~ 180 millimeters to locate to form one at distribution plate body 1's center and use this section distance as the circular region that radial does not set up trompil 2 and be the disc, detachably is connected with the toper cylinder on the disc, and middle toper cylinder can be with screwed connection with the distribution plate, and after the toper cylinder, the wind of coming in from fluidized bed bottom storehouse can be along toper cylinder upward rotation, more is favorable to the material to boil upwards. In addition, this kind of distribution plate more is favorable to the vacuum ejection of compact, and the material can connect the whole granulator of vacuum ejection of compact after the fluidized bed, and fluidized bed vacuum discharge gate sets up in the distribution plate top, and like this, the material more is favorable to the vacuum ejection of compact cleaner along toper cylinder rebound.
The embodiment of the utility model provides an in, trompil 2 is arranging on the distributing plate body 1 and is trompil 2 density from inside to outside and from little grow, and the surface area on the distributing plate body 1 is by little grow from inside to outside, from this, sets up trompil 2 according to the characteristics of distributing plate body 1, can increase trompil 2 rate to the regional make full use of distributing plate body 1 from inside to outside, makes the abundant boiling of material.
The embodiment of the utility model provides a still provide a fluidized bed, it includes fluidized bed end storehouse and material storehouse and as above-mentioned technical scheme the distributing plate for the fluidized bed, the setting is linked together along the air current direction in proper order in storehouse, for the fluidized bed distributing plate and material storehouse at the bottom of the fluidized bed. The inclined holes 2 are distributed on the distribution plate for the fluidized bed, so that the direction of wind is changed after the wind passes through the distribution plate, the wind spirally enters a material bin above the distribution plate along the inclined direction of the holes 2, and the material in the material bin is fully rotated and boiled; therefore, the vacuum discharge is more facilitated, the materials are directly sucked into a discharge container (generally a vacuum discharge granulator) or other machines directly butted with a dryer, and the closed dustless production is more facilitated. In addition, through on the central disc of distribution plate body detachably be connected with the toper cylinder, the wind that comes from fluidized bed bottom storehouse can upwards rotate along the toper cylinder, more is favorable to the material to upwards boil. In addition, this kind of distribution plate more is favorable to the vacuum ejection of compact, and the material can connect the whole granulator of vacuum ejection of compact after the fluidized bed, and fluidized bed vacuum discharge gate sets up in the distribution plate top, and like this, the material more is favorable to the vacuum ejection of compact cleaner along toper cylinder rebound.
Can see by above embodiment, the utility model discloses a to the form change that sets up of trompil, can make the abundant boiling of material to no dead angle, the percent opening of distribution board is high, reaches the abundant dry purpose of material.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
