Abstract

A drum dryer consists of an arch-breaking auger, a lifting auger, a feeding auger, a crusher, a drying drum, a discharging auger, a dust remover, an induced draft fan and a chimney which are connected with each other in sequence. A crushing shaft of the crusher is through shaft type and passes through the whole drying drum, and crushing teeth are fully distributed on the crushing shaft. The drum dryer has the advantages that: as the crushing shaft of the crusher passes through the whole drying drum, and crushing teeth are fully distributed on the whole crushing shaft, the crusher constantly rotates in a drum body along with the crushing shaft under the driving of a speed regulating motor, and materials which contact with the crushing shaft can be crushed; therefore, the materials are fully crushed inside the drum from feeding to discharging, and the agglomeration rate is reduced, thus improving the drying efficiency.

Description

Novel roller drier

Technical field:

The utility model belongs to a kind of drying equipment that is used for dry various materials, particularly a kind of roller drier.

Background technology:

Existing whizzer be used for dry viscosity bigger material the time, stick on the barrel and prevent that in order to reduce material material from forming piece, the terminal at revolving drier that has is installed the suspended chain bar and is pulverized as the centre, to increase the per surface area that material contacts with gas.For the material that is bonded on the barrel is fallen, the weight of adorning outside cylindrical shell that also has carries out rapping.But for the bigger material of viscosity, these devices still can not be dealt with problems sometimes fully.Material easily caking is difficult for fragmentation, after drying is come out, forms the ball that much differs in size, and it is wet that the inside is stuck with paste on the surface of ball, and the balling phenomenon is serious, has influenced rate of drying.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of roller drier is provided, and this drying machine can improve crushing efficiency, and material is contacted with thermal source well, improves rate of drying.

The technical solution of the utility model is: a kind of roller drier, connect to form successively by broken arch strand cage, lifting strand cage, pan feeding strand cage, destroyer, drying drum, discharging strand cage, deduster, air-introduced machine and chimney, it is characterized in that: the broken shaft of destroyer is the axis type, run through whole drying drum, be covered with crushing teeth on the broken shaft.

Said drying drum, destroyer and broken arch strand cage all adopt stepless speed regulation to drive.

The utility model has the advantages that: because the broken shaft of destroyer runs through whole drying drum, and on whole broken shaft, be covered with crushing teeth, therefore destroyer is under the drive of buncher, the rotation that in cylindrical shell, does not stop along with broken shaft, the material that contacts with broken shaft can be broken, and like this, material is fully broken from going into to expect discharging in cylinder inside, reduce the balling rate, thereby improved drying efficiency.

Description of drawings:

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

Fig. 2 is the schematic diagram of broken shaft.

Fig. 3 is the side view of Fig. 2.

Fig. 4 is the schematic diagram of stepless speed regulation.

The specific embodiment:

As shown in the figure: the broken arch strand of 1-cage, 2-promote strand cage, 3-pan feeding strand cage, 4-destroyer, 5-drying drum, 6-discharging strand cage, 7-deduster, 8-air-introduced machine, 9-chimney 10-combustion furnace, 11-broken shaft, 12-crushing teeth, 13-gear wheel, 14-pinion, 15-reductor, 16-belt pulley, 17-buncher, 18-support roller assembly, 19-sheave assembly.

Roller drier is connected to form successively by broken arch strand cage 1, lifting strand cage 2, pan feeding strand cage 3, destroyer 4, drying drum 5, discharging strand cage 6, deduster 7, air-introduced machine 8 and chimney 9.The broken shaft 11 of destroyer is the axis type, and it runs through whole drying drum, is covered with crushing teeth 12 on the broken shaft.Drying drum tilts to support by support roller assembly and sheave assembly.Said drying drum, destroyer and broken arch strand cage all adopt stepless speed regulation to drive, and can adapt to the drying requirement of heterogeneity material like this, also can realize quantitative automatic feeding.Stepless speed regulation is connected to form successively by intermeshing large and

small gear

13,14, reductor 15, belt pulley 16 and buncher 17.

Operation principle of the present utility model is:

High moisture material is quantitatively sent in the drying drum dryer through broken arch strand cage, lifting strand cage and pan feeding strand cage, the anterior destroyer of rotation at a high speed of the cylinder that is dried smashes, because the broken shaft of destroyer runs through whole drying drum, and on whole broken shaft, be covered with crushing teeth, therefore destroyer is under the drive of buncher, the rotation that in cylindrical shell, does not stop along with broken shaft, the material that contacts with broken shaft can be broken, like this, material is fully broken from going into to expect discharging in cylinder inside, thereby forms a homodisperse stock column that flies upward in the inner chamber body of whole cylinder.This continuous stock column fully contacts with the high-temperature flue gas of combustion furnace input, finishes the mass-and heat-transfer process.Because the inclination angle of cylinder and the effect of air-introduced machine, material is slowly moved to discharge end by feed end, and dry products is even fine granularity and discharges from discharging strand cage.Reclaimed by deduster by the powder of air-introduced machine sucking-off on a small quantity.

Claims

1, a kind of roller drier, connect to form successively by broken arch strand cage, lifting strand cage, pan feeding strand cage, destroyer, drying drum, discharging strand cage, deduster, air-introduced machine and chimney, it is characterized in that: the broken shaft of destroyer is the axis type, run through whole drying drum, be covered with crushing teeth on the broken shaft.

2, roller drier according to claim 1 is characterized in that: said drying drum, destroyer and broken arch strand cage all adopt stepless speed regulation to drive.
