Abstract

The utility model discloses an auger type drier used for materiel drying which comprises a frame, an electric machine, a gear box, an auger shell, an auger axis, an auger, a feeding opening, and a discharge opening. The auger shell is formed through connection of an auger pot and an auger groove. The external end of the auger pot is provided with the feeding opening and the external end of the auger groove is provided with the discharge opening. The top of the auger pot is provided with a preheating pan whose head end has the discharge opening which is communicated with the feeding opening of the auger pot. Top of the preheating pan has a preheating auger whose top has a material disparting board. The utility model has the advantages of full utilization of heat energy and good drying effect.

Description

The auger type drying machine

The utility model relates to a kind of drying equipment of material.

Its heated part of existing material drier generally is the structure of sealing, after material is heated therein, though steam and feed separation, but owing to can not in time get rid of steam in enclosed construction, it is not saturating that material is done, and influenced drying effect, for example Chinese patent CN2238407Y discloses a kind of like this structure, after material was heated in rotating cylinder, the steam of evaporation will arrive discharging opening always could be separated with material, so the dry materials effect is bad.

The purpose of this utility model is to provide a kind of can make full use of heat energy and the good drying machine of drying effect.

In order to achieve the above object, the utility model adopts following technical scheme: a kind of auger type drying machine, comprise frame, motor, reduction box, auger shell and auger thereof, motor is by reduction box and screw-conveyer-shaft load, have charging aperture and discharging opening on the auger shell, the auger shell is formed by connecting by auger tube and auger groove, and the outer end of auger tube has charging aperture, and the outer end of auger groove has discharging opening; The top of auger tube has foreheater, and the head end of foreheater has discharging opening, and this discharging opening is connected with the charging aperture of auger tube; The top of foreheater has the preheating auger, and the top of preheating auger has cutting plate, and cutting plate is fixedly connected in the foreheater, and pre-thermoelectric perpetual motion machine is by reduction box and the load of preheating screw-conveyer-shaft.

After adopting said structure, because the auger shell is formed by connecting by auger tube and auger groove, the material that heats in the auger tube just rolls subsequently and advances in the auger groove, the auger groove is a unenclosed construction, most of steam can volatilize away rapidly, volatilize gradually totally when all the other moisture content run to discharging opening with material, this makes dry materials thorough, and drying effect is good; Because the top of auger tube has foreheater, material obtained earlier preheating in foreheater before entering the formal heating of auger tube again, this foreheater utilizes the waste heat of auger tube with the material preheating, evaporate a part of steam, so both made full use of heat energy, make the dry materials better effects if again.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the structural representation of auger type drying machine of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the cutaway view of Fig. 1 along the A-A line;

Fig. 4 is the cutaway view of Fig. 1 along the B-B line;

Fig. 5 is the cutaway view of Fig. 1 along the C-C line.

As Fig. 1,2,3, shown in 4, auger type drying machine of the present utility model, comprise frame 5, motor 1, reduction box 2, auger shell 16 and auger 4, motor 1 is by reduction box 2 and screw-conveyer-shaft 3 loads, have charging aperture 13 and discharging opening 17 on the auger shell 16, auger shell 16 has two, every auger shell 16 is formed by connecting by auger tube 14 and auger groove 6, an auger 4 is all arranged in the every auger shell 16, the outer end of each auger tube 14 has charging aperture 13, the outer end of each auger groove 6 has discharging opening 17, the top of auger tube 14 has foreheater 20, and the head end of foreheater 20 has discharging opening 21, and this discharging opening 21 is connected with the charging aperture 13 of auger tube 14, the top of foreheater 20 has preheating auger 9, the top of preheating auger 9 has cutting plate 11, and cutting plate 11 is fixedly connected in the foreheater 20, and pre-thermoelectric perpetual motion machine 7 is by

reduction box

8 and 12 loads of preheating screw-conveyer-shaft.Cutting plate 11 tops are fixed with support bar 10, and support bar 10 two ends are connected in the foreheater 20, between cutting plate 11 and the foreheater 20 charging space 23 are arranged.The pusher direction of preheating auger 9 is opposite with the pusher direction of auger 4.Heating furnace 15 is contained in the below of auger tube 14.

Shown in Fig. 1,5, discharging opening 17 places of auger groove 6 are fitted with discharge bucket 22, and sieve 19 is housed in the discharge bucket 22.Discharging auger 18 is equipped with in discharge bucket 22 bottoms, is convenient to mass transport with drying like this in charge cask.Discharge bucket 22, sieve 19 and discharging auger 18 also can.

The utility model can be built heating furnace 15 by laying bricks or stones before using below auger tube 14, and builds the flue of heating furnace below auger groove 6 by laying bricks or stones.During the utility model work, as shown in Figure 1, 2, the material of water content is poured on the cutting plate 11 on the preheating auger 9, material enters preheating auger 9 along the charging space 23 between cutting plate 11 and the foreheater 20, the following preheating of promotion limit at preheating auger 9 moves ahead, a part of steam has volatilized, then, enter into the charging aperture 13 of two auger tubes 14 by the discharging opening 21 of foreheater 20, heating and rolling in two auger tubes 14 is because the auger tube can be provided with heating furnace 15 14 times, therefore, the not only hurried rising of temperature, and make moisture content continue evaporation.When the material of heat is shifted onto in the unlimited auger groove 6 by auger 4 after, at this moment, most of steam is discharged rapidly, and material vapors away gradually with the rolling operation of material in the auger groove 6 of the flue residue heat heating that is subjected to heating furnace, walk to discharging opening 17 subsequently, through discharge bucket 22,

sieve

19 and 18 outputs of discharging auger, dry material just can have been packed container into again.
