Abstract

The utility model relates to a novel vertical type disc drier which is mainly composed of a barrel body, a disc, impellers, an air inlet discharge pipe, an air outlet discharge pipe, a speed regulating mechanism, a main shaft, a ring, etc. Material is added in the disc drier from the top part, and moves from top to bottom under the stirring action of two sets of impellers on the disc; simultaneously, the material is heat by conduction, radiation and convection, as a result, the heat exchange coefficient of the drier is extremely high, treating capacity of unit heating area is large, and finally uniform dry product can be obtained. The utility model has the advantages of novel structure and reasonable design, and is a new generation of vertical type drying device.

Description

The novel vertical disk dryer

The utility model belongs to drying device, relates to a kind of vertical disc drier that simultaneously material is heated with disk and hot blast.

Some vertical disc driers exist following problem in the prior art: the device that has has been strengthened rate of drying but has been ignored the utilization rate of heat energy; What have on the contrary then is that energy utilization rate is higher, but rate of drying is low relatively.

The purpose of this utility model is to provide a kind of efficient, energy-conservation vertical disc drier that collects conduction, radiation, convection current three reheating.

The technical solution of the utility model is: adopt cylindrical shell 10 top-feeds, object alternately by the two groups of

impellers

7,8 on the disk 6 from top to bottom, interior receipts, be extrapolated to discharging opening 17.Meanwhile hot blast feeds the interlayer of disks 6 through a side comb 13, flows out from opposite side comb 5, enters in the tube at the bottom of wherein one road hot blast feeds tin more thereafter, shuttles back and forth inside and outside disk 6, and risings of spiraling is from the discharge of tube top.Material is subjected to the multiple heating of disk 6 upper and lower surfaces and hot blast in this process, has improved the coefficient of heat transfer thus widely, and it is compact, efficient that device becomes.

As above-mentioned, the utility model structure mainly is made of cylindrical shell 10, disk 6,

impeller

7,8, inlet,

outlet comb

5,13, speed adjusting gear 1, main shaft 2, ring 9 etc.Charge door 12 and exhaust outlet 11 are set at the top of cylindrical shell 10; Bottom center is provided with speed adjusting gear 1, and (speed of its control main shaft 2) bottom left is a storing logical sequence 15, and its underpart is a discharging opening 17, is connecting push-pull valve 16 between the two.Arranging multi-layer discs 6 in the cylindrical shell 10 equidistantly, each disk all have include interlayer, inside and outside around the sealing two top and bottom, bottom surface is coated a kind of far ultrared paint.Disk 6 has two groups, and is arranging their compartment of terrains, simultaneously on the disk 6 also the compartment of terrain laying two groups of

agitator arms

7,8, they are fixed on the main shaft 2 and with main shaft 2 and rotate synchronously.There is a macropore in one group of disk 6 central authorities, and from then on material falls down in the hole, and air-flow can be by rising on this hole, and disk 6 outer rims also are provided with a ring 9; And another group disk 6 outer rims are not established ring 9, and central authorities also do not establish the hole, but the central authorities top is provided with an arc surface 14, and the material that its effect causes to fall and break can be uniform.In being respectively, receive two groups of

agitator arms

7,8 impeller 8 and extrapolation impeller 7.Interior out rotor 8 is arranged in outer rim to be had on the disk 6 of ring 9, and its blade arc is spill with turning to, and during the blade rotation, can gradually in the income dish medium pore, drop down onto the material on the disk 6 on next card; Extrapolation impeller 7 is then opposite, and its blade arc is convex with turning to, and during the blade rotation, can push away disk 6 edges to the material on the disk 6 gradually to next card.The left-external side of cylindrical shell 10 is an air inlet comb 13, and the right outside is the comb 5 of giving vent to anger, and every pair of arm is connecting the interlayer of disk 6; And the lower end of the comb 5 of giving vent to anger is divided into two the tunnel, the one tunnel and enters cylindrical shell 10 bottoms, and its flow size is by flow control valve 4 controls, and another road is then sent to heating to the air-flow of remainder, recycles.

The utility model has the advantages that: 1, coefficient of heat transfer height and relatively heat transfer area is little.Add by the synergistic effect of three reheating and the material that stirs of stirring vane can make the coefficient of heat transfer up to 52-112W/M ²℃.2, thermal efficiency height is kind of an energy-conservation drier.Because hot blast carries out heat exchange by disk 6 interlayers, feed cylindrical shell 10 again from the bottom by disk 6 with spiraling, prolonged the time of staying of hot blast in tube, heat is fully drawn by material.3, can get the dry products of homogeneous.This is because the disk 6 of multilayer and the effect of two groups of

agitator arms

7,8 make material be in cylindrical shell 10 in the motion constantly, so all materials are heated, dry equal-opportunity cause.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the schematic top plan view of interior receipts impeller.

Fig. 3 is the schematic top plan view of extrapolation impeller.

The number in the figure explanation:

1-speed adjusting gear 2-main shaft 3-bottom inflow pipe

The 4-flow control valve 5-comb 6-disk of giving vent to anger

Receive impeller 9 rings in the 7-extrapolation impeller 8-

10-cylindrical shell 11-exhaust outlet 12-charge door

13-air inlet comb 14-arc surface 15-storing logical sequence

16-push-pull valve 17-discharging opening

See also Fig. 1, starting speed adjusting gear 1 is under main shaft 2 drives, two groups of

impellers

7,8 rotate synchronously with main shaft 2, and material adds continuously and quantitatively from the charge door 12 on tube top, and material drops on the edge of disk 6, since ring 9 stop that it can not fallen second disk 6 and get on.Interior receipts impeller 8 on first disk 6 drops in second disk 6 material, and is distributed on second card along arc surface 14 along with rotation is held together the material gradually closing in the hole of disk 6 central authorities; Extrapolation impeller 7 on this moment second disk 6 little by little pushes away material on the edge of three disks 6 in rule edge to the.Meanwhile hot blast enters from the air inlet comb 13 of cylindrical shell 10 left-external sides, passes the interlayer that each arm flows into disk 6.Material on the card is being stirred by

impeller

7,8 on one side, Yi Bian be subjected to the conduction heating of hot card; And the bottom surface of disk 6 has been coated with far ultrared paint, and it carries out radiation heating to the material on next card.The hot blast that flows in the interlayer constantly flows out from the comb 5 of giving vent to anger on right side again, and the following pipe end of the comb 5 of giving vent to anger divides two the tunnel again, and under the control of flow control valve 4, the part hot blast enters in the cylindrical shell 10 by bottom inflow pipe 3, and remaining hot blast returns heating, recycles.

The bottom hot blast penetrates in the middle of the medium pore of the most next disk 6, along card to around the diffusion, material on the card is carried out Convective Heating, thereafter the ring 9 from the plate edge returns up, enters on time lower floor's card, again the material on this card is carried out Convective Heating, and then from coil central authorities the hole put on, so operation arrives at last and goes up most a card, is carrying moisture secretly and is discharging from exhaust outlet 11.And material falls into storing logical sequence 15 at last under two groups of

impellers

7,8 and effect, discharges from discharging opening 17 continuously or periodically.

The utility model novel structure, reasonable in design is the vertical type drying apparatus of a new generation; Its floor space is little, and unit heating surface (area) (HS treating capacity is big, and the dry products that can obtain final homogeneous.
