Abstract

The utility model relates to a super-fine particle drier, which is mainly composed of a barrel body, a charging tray, a carrying tray, an electric heater, a stirrer, a speed reducer, a rotating shaft, etc. The device of the utility model adopts heat-conduction heating; the charging tray rotates continuously; material is continuously stirred; wet waste gas is exasuted in a controllable mode. The result material of the utility model has uniform heating temperature and high drying speed, and particles are not dispersed. The device of the utility model can dry various superfine particles, and is effective and practical.

Description

The ultra-fine grain drying machine

The utility model relates to a kind of drying machine, specifically a kind of drying device that is used for ultra-fine grain.

In the patent No. is 99227792.2 " rotation stir pan dryer ", owing to adopt hot air circulation to come dried material, be ultra-fine grain as material, might be recycled wind and loose; Again since charging tray pick and place also not too convenient, so be necessary to be improved so that adapt to dry ultra-fine grain.

The purpose of this utility model is to provide a kind of effective, practical ultra-fine grain drying device that can address the above problem.

Technical solution of the present utility model is: with electric heater indirectly by heat conduct add thermal material and in the material disc of rotation material stirred continuously, it is dry to make material integral body obtain comparatively fast and synchronously.

As above-mentioned, structure of the present utility model mainly is made of cylindrical shell 2, charging tray 6, pallet 5, electric heater 4, agitator 21, decelerator 17,22, rotating shaft 11 etc.Flatly equidistantly arranging one group of pallet 5 in cylindrical shell 2, they are being supported by three groups of supporting plates 19 on three locating shafts 9 that are distributed on pallet 5 peripheries, are arranging three groups of location bearings 18 above the supporting plate 19, and they tightly are trapped among the periphery of pallet 5.The central authorities of pallet 5 are a roundel, and it welds with four vertical each other gussets mutually with pallet 5 outer interannulars, just contains the scallop hole of four homalographics like this in the pallet 5.Charging tray 6 is placed on above the pallet 5, and makes it the location, does not move when rotating; There is a back-up ring (interior not blowing) in the central authorities of charging tray 6.The tight cloth in upper horizontal ground of charging tray 6 one group of agitator 21, and it is by one group of small pulley 20 driven rotary that is positioned at cylindrical shell 2 outsides, and small pulley 20 is being controlled rotating speed by the little decelerator 22 of its bottom.Welding one pallet belt wheel 14 below the central disk of pallet 5 again, at vertical rotation axis 11 of right arranged outside of pallet 5, the one group of rotating shaft belt wheel 12 that all distributing in the rotating shaft 11, they and pallet belt wheel 14 are in the same plane.Linking with heatproof zone 13 between the two-wheeled, rotating shaft 11 is being fixed with bearing block 15 up and down, the rotating shaft 11 bottoms transition pulley 16 of ining succession again, and it is being controlled by big retarding device 17 and is rotating.Below pallet 5, arranging one group equally spacedly every dish 3, arranging electric heater 4 on the dish, be fixed on the inwall of cylindrical shell 2 every dish 3.The left-external side of pallet 5 is being arranged the oblique upside in a left side that 8, one groups of equally spaced exhaust duct inlets 7 of an exhaust duct are positioned at charging tray 6, and the top of exhaust duct 8 is provided with the blast pipe 10 of an adjustable tolerance.The fresh wind tube 1 of one adjustable air quantity is set in the middle of the bottom of cylindrical shell, the filtered air material is housed in the pipe.

The utility model has the advantages that:

1. charging tray 6 can freely take out easily.(comparing) with patent 99227792.2

2. when operation, pallet 5 drives charging trays 6 rotations and material is subjected to continuous stirring, and material is subjected to the conduction heating and temperature is even, and has rate of drying faster.

3. getting rid of naturally of controlled humidity system, can not make the material loss.

Fig. 3 the utility model A-A side is cutd open structure chart.

The number in the figure explanation: 1-fresh wind tube 2-cylindrical shell 3-stirs the little decelerator 23-of 22-door every dish 4-electric heater 5-pallet 6-charging tray 7-exhaust duct inlet 8-exhaust duct 9-locating shaft 10-blast pipe 11-rotating shaft 12-rotating shaft belt wheel 13-heatproof zone 14 pallet belt wheel 15-bearing block 16-transition pulley 17-big retarding device 18-location bearing 19-supporting plate 20-small pulley 21-

Be described further below in conjunction with accompanying drawing: open door 23, the charging tray 6 that installs material is put into fixed position on the pallet 5, close and call 23, start large and small decelerator 17,22 and electric heater 4.Material in the charging tray 6 is subjected to agitator 21 on one side and stirs continuously, the heat of getting back on one side conduction heating makes that the interior moisture content of material is evaporated equably, controls the air quantity of fresh wind tube 1 simultaneously, new wind is accompanied by wet waste gas and enters exhaust duct 8 from exhaust duct inlet 7, discharges from blast pipe 10 again.

The utility model has been made important improvement on the basis of patent " pan dryer is stirred in rotation ", make it to become the device of effectively expecting usefulness of the dry all kinds of ultra-fine grains of energy.
