Abstract

A grabbing plate with variable sections of a dryer for organic-substance particle fertilizer is provided, which is characterized in that the section of the grabbing plate with variable sections become gradually bigger from the smaller end to the bigger end.

Description

A kind of variable cross-section flight device of biologic grain fertilizer drying machine

Affiliated technical field:

The utility model relates to a kind of variable cross-section flight device of biologic grain fertilizer drying machine, especially can make the evenly dry variable cross-section flight device of biologic grain fertilizer in the machine.

Background technology:

At present, moisture was bigger after biologic grain fertilizer was granulated, and easily bondd between the particle, must carry out mechanical drying.Known grain drier is not suitable for drying biologic grain fertilizer, traditional drumdrier can dry biologic grain fertilizer, but its inner flight adopts the rectangular steel plates structure more, the rectangular steel plates flight is simple in structure, processing and manufacturing is easy, that adopts is many, but can not will be evenly distributed by the oven dry granulated fertilizer in the machine.Poor, the not anti-storage of finished particle fertilizer uniform drying degree, powder is separated easily, and dry production efficiency is low.The flight structure that also has a kind of central angle to change, distributing homogeneity is good slightly, but difficulty of processing and installation difficulty are all big, seldom adopt.

Summary of the invention:

In order to overcome the deficiency of the dry biologic grain fertilizer of existing drying machine, the utility model provides a kind of novel drum-type biologic grain fertilizer drying machine variable cross-section flight device (Fig. 4), this device can not only make the interior fertilizer of machine be evenly distributed, and can make the fertilizer uniform drying, improves drying efficiency.

The technical scheme that its technical problem that solves the utility model adopts is: the variable cross-section flight device (Fig. 4) that many rows that are welded in dryer drum (Fig. 1) fold with steel plate, the different cross section 2 of barrel 1 and variable cross-section flight device as can be seen from dryer drum sectional view (Fig. 2), the cross section (Fig. 5) of the variable cross-section flight device of this bio-feritlizer drying machine is to become big gradually from small end to big end, variable cross-section flight device is pressed 36 ° of central angle installations spaced apart in dryer drum, line is arranged in the shape of a spiral on the rotating cylinder developed surface.When rotating cylinder rotates, variable cross-section flight device will enter the granulated fertilizer of rotating cylinder bottom and take up, because the effect of variable cross-section flight device changes of section and bent angle, the fertilizer on the flight are then progressively slided from flight with rotating cylinder angle position difference, scatter among the rotating cylinder space.Fertilizer on the same variable cross-section flight device begins to shed when rotating cylinder upwards forwards horizontal center line to, sheds end when spreading near the horizontal center line other end while changeing, and just evenly spreads all over the rotating cylinder cross section.Rotating cylinder is not stopping rotation, and each piece variable cross-section flight device can both be with the material of rotating cylinder bottom

Take up and shed, fertilizer enters into discharge end from the rotating cylinder feed end and discharges, and is repeatedly taken up and sheds by a plurality of variable cross-section flight devices, and fertilizer is repeatedly contacted with drying medium, drying medium is taken away the moisture in the fertilizer, reaches the purpose that improves drying efficiency, even dry fertilizer.

The beneficial effects of the utility model are: when rotating cylinder rotated, the fertilizer that variable cross-section flight device is taken up is Sa Full rotating cylinder cross section uniformly, made bio-feritlizer and drying medium even contact, the purpose of reach uniform drying, boosting productivity.

The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings:

Fig. 1 is the rotating cylinder outline drawing of the drum-type biologic grain fertilizer drying machine of the utility model embodiment

Fig. 2 is that the utility model variable cross-section flight device is installed in the cross-sectional view in the dryer drum

Fig. 3 is the little end-view of variable cross-section flight device.

Fig. 4 is a single variable cross-section flight device front view before being welded.

Fig. 6 is that variable cross-section flight device is at rotating cylinder developed surface Pareto diagram.

The specific embodiment:

The long 400mm of variable cross-section flight device (Fig. 4), fold moulding with thick 4mm steel plate, folding is divided into 1 ladder plane and 2 triangle projective planums along its length, be respectively a face, b face and c face on variable cross-section flight device cross section (Fig. 5), a face and b face angle are 135 °, and b face and c face angle are 135 °, a face small end (Fig. 3) length of side 30mm, big end length of side 50mm, b face triangle minor face is long to be 40mm, c face triangle minor face length is 35mm.The cross section (Fig. 5) of variable cross-section flight device is to become big gradually from small end to big end.Per 1 circle has 10 variable cross-section flight devices in rotating cylinder, and is spaced apart by 36 ° of central angles, the independently long edge of a face tube rotaring axis parallel direction and the welding of rotating cylinder inwall, and a face vertical direction is aimed at the rotating cylinder axle center.The variable cross-section flight device of two adjacent rings staggers 9 ° at the rotating cylinder circumferencial direction, and at the rotating cylinder length direction 100mm that staggers, line is arranged (Fig. 6) in the shape of a spiral on the rotating cylinder developed surface.
