Abstract

The invention provides a hot air dryer with auxiliary plates. The hot air dryer comprises a transmission part, a bearing part and a rotary drum, wherein the interior of the rotary drum is provided with guide plates, the auxiliary plates and throwing plate; the guide plates are spiral and are arranged on the feed inlet of the rotary drum; the auxiliary plates are arranged at a certain distance from the guide plates, the region between the guide plates and the auxiliary plates is a secondary pelleting area, the auxiliary plates are evenly distributed on the inner wall of the rotary drum at intervals; the auxiliary plates are rectangular plates, the long axes of the auxiliary plates are in parallel with the that of the rotary drum, and the short axes of the auxiliary plates are perpendicular to the inner wall of the rotary drum; the auxiliary plate can be divided into four levels from the side of the guide plate, namely a first-level auxiliary plate, a second-level auxiliary plate, a third-level auxiliary plate and a fourth-level auxiliary plate, the height of the auxiliary plates extruding to the cavity of the rotary drum can be increased level by level; the uniformly-distributed throwing plates are arranged between the auxiliary plates and the discharge hole of the rotary drum. The hot wind dryer with the auxiliary plates provided by the invention has the advantage of better drying effect.

Description

A kind of air flow dryer that has the power-assist plate

Technical field

The present invention relates to a kind of air flow dryer, particularly a kind of air flow dryer that has the power-assist plate.

Background technology

When solid material is dried, commonly used to equipment be air flow dryer, air flow dryer is supporting to have hot-blast stove and air-introduced machine; Hot blast is blown in the rotating cylinder of air flow dryer; Hot blast fully contacts in rotating cylinder with material, and oven dry material contained humidity reaches the purpose of drying material.Improving drying effect is the developing direction of air flow dryer.

Summary of the invention

In order to improve the drying effect of existing air flow dryer, the present invention provides a kind of air flow dryer that has the power-assist plate.

Technical scheme of the present invention is: a kind of air flow dryer that has the power-assist plate comprises: running part, supporting part and rotating cylinder.Wherein, be provided with stock guide, power-assist plate and lifting blade in the rotating cylinder.Stock guide is a screw type, is arranged at charging aperture place in the rotating cylinder.Be provided with the power-assist plate apart from stock guide a distance, the zone between stock guide and the power-assist plate is the secondary granulation district, and the power-assist plate is evenly spaced apart in the rotating cylinder inwall.The power-assist plate is major axis and rotating cylinder axis, the minor axis rectangular slab perpendicular to the rotating cylinder inwall.The power-assist plate is divided into 4 grades, begins to be respectively one-level power-assist plate, secondary power-assist plate, three grades of power-assist plates and level Four power-assist plate from the stock guide side, and the protruding height in the rotating cylinder chamber of power-assist plate increases step by step.Be provided with equally distributed lifting blade between power-assist plate and the rotating cylinder discharging opening.

During use, dryer work, rotating cylinder rotates.Send into material and be blown into hot blast through the rotating cylinder charging aperture.Material gets into the secondary granulation district through stock guide, and rotates to roll with rotating cylinder in the secondary granulation district and carry out secondary granulation.Material contacts with the power-assist plate then; The power-assist plate increases material and rolls, and stops the longer time, thereby it is more abundant that material is contacted with hot blast; Because in rotating cylinder; The hot blast at nearly charging aperture place is higher and humidity is lower than the temperature of the hot blast of nearly discharging opening, and the drying effect at therefore nearly charging aperture place is also good than nearly discharging opening place, so the power-assist plate can make material better by hot-air seasoning.The power-assist plate that increases highly gradually reduces the rolling number of times of material gradually, carry out the transition to lifting blade after, material is kicked up by lifting blade, continues to be dried.Material leaves rotating cylinder through the oven dry back by discharging opening, gets into subsequent handling.

The invention has the beneficial effects as follows that the present invention provides a kind of air flow dryer that has the power-assist plate, has better drying effect.

Description of drawings

Below in conjunction with accompanying drawing the present invention is further specified.

Fig. 1 is the front view of embodiments of the invention;

Fig. 2 is the cutaway view of A-A1 among Fig. 1.

In Fig. 1 and Fig. 2, a kind of air flow dryer that has the power-assist plate comprises: running part, supporting part and rotating cylinder 3.

Running part comprises motor 11, reductor 12, pinion 13, gear wheel 14.Gear wheel 14 is fixed in rotating cylinder 3 outer walls, and coincide with pinion 13, and pinion 13 is connected with the motor that power is provided 11 via reductor 12.

Supporting part comprises rolling ring 21 and support roller 22.Rotating cylinder 3 outer walls are fixed in rolling ring 21, are seated on the support roller 22.

Be provided with stock guide 31, power-assist plate 32 and lifting blade 33 in the rotating cylinder 3.Stock guide 31 is a screw type, is arranged at charging aperture 301 places in the rotating cylinder 3.Be provided with power-assist plate 32 apart from stock guide 31 a distance, the zone between stock guide 31 and the power-assist plate 32 is secondary granulation district 302, and power-assist plate 32 is evenly spaced apart in rotating cylinder 3 inwalls.Power-assist plate 32 is major axis and rotating cylinder axis, the minor axis rectangular slab perpendicular to the rotating cylinder inwall.Power-assist plate 32 is divided into 4 grades, begins to be respectively one-level power-assist plate 321, secondary power-assist plate 322, three grades of power-assist plates 323 and level Four power-assist plates 324 from the stock guide side, and power-assist plate 32 protruding height in rotating cylinder 3 chambeies increase step by step.Be provided with equally distributed lifting blade 33 between level Four power-assist plate 324 and rotating cylinder 3 discharging openings 303.

During use, dryer work, rotating cylinder 3 rotates.Send into material and be blown into hot blast through rotating cylinder 3 charging apertures 301.Material gets into secondary granulation districts 302 through stock guide 31, and rotates to roll with rotating cylinder 3 in secondary granulation district 302 and carry out secondary granulation.Material contacts with power-assist plate 32 then; Power-assist plate 32 increases material and rolls, and stops the longer time, thereby it is more abundant that material is contacted with hot blast; Because in rotating cylinder 3; The hot blast at nearly charging aperture 301 places is higher and humidity is lower than the temperature of the hot blast of nearly discharging opening 303, and the drying effect at therefore nearly charging aperture 301 places is also good than nearly discharging opening 303 places, so power-assist plate 32 can make material better by hot-air seasoning.The power-assist plate 32 that increases highly gradually reduces the rolling number of times of material gradually, carry out the transition to lifting blade 33 after, material is kicked up by lifting blade 33, continues to be dried.Material leaves rotating cylinder 3 through the oven dry back by discharging opening 303, gets into subsequent handling.
