Abstract

The utility model relates to a vertical double-rotary wheel drier for paste materials, which is mainly composed of a barrel body, a double-rotary wheel, a rotating shaft with a spiral sheet, a heating cover and a motor, wherein, the barrel body is composed of a crushing chamber, a temperature equalizing chamber, a separation chamber and an annular air chamber. When paste materials are added to the crushing chamber, the materials are crushed under the high-speed rotating action of the double-rotary wheel and are simultaneously heated by a hot air flow, and the materials are reduced again in company with the evaporation of water; the materials orderly pass through the temperature equalizing chamber and the separation chamber, the materials are further dried in the temperature equalizing chamber, are separated in the separation chamber and then are discharged from a discharge port of the lower part of the separation chamber, and an air flow passes through a separating plate to be discharged from an exhaust port through the annular air chamber.

Description

Vertical double rotary wheel paste material drying machine

The utility model relates to a kind of rapid drying device that is used for paste material.

In the prior art, it is extremely slow to handle the speed that the drying cartridge of paste material is equipped with; Though the speed that has is fast, need join the huge after-treatment device of a cover in addition, carry out gas solid separation.

The purpose of this utility model is to provide a kind of novel vertical double rotary wheel drying machine that integrates paste material pulverizing, heating, gas solid separation.

The technical solution of the utility model is: adopt the opposite at a high speed spinning roller that rotates of a pair of in pulverizing chamber, paste material is pulverized, the thermal current of jet pipe ejection simultaneously adds hot feed; Follow broken relatively dry material in thermostatic chamber, obtain further drying, under the effect of high-speed screw sheet, material is thrown toward barrel subsequently, discharges from the bottom discharging opening, gas then passes separating plate and up discharges from exhaust outlet.

As above-mentioned, the utility model structure mainly is made of cylindrical shell 15, double

rotary wheel

19,21, the rotating shaft 12 of being with flight 14, heating mantles 16, motor 11,22 etc., and cylindrical shell is separated into pulverizing chamber 2, equal greenhouse 4, separation chamber 8, ring-shaped air chamber 5.A motor 22 is settled at the top of cylindrical shell 15, and it is driving goes up spinning roller 21 rotations.The tilting charge pipe 1 in cylindrical shell 15 upper left sides, its bottom leads to pulverizing chamber 2.The rotating shaft 12 of motor 11 drives and the following spinning roller 19 (it and last spinning roller 21 be setting-in each other) in the pulverizing chamber 2 is by connecting down.These double

rotary wheel

19,21 their direction of rotation are opposite, and rotating speed is slightly big or small, and each spinning roller all has the annulus up and down of twice different-diameter, link with 8-12 root vertical bars between the annulus up and down, and following ring is gone up the uniform wheel hub of spoke binding dressing on motor shaft.Ventilating board 3 is separated pulverizing chamber 2 and equal greenhouse 4, is arranging one group of air vent on it.All greenhouse 4 is surrounded by the heating mantles 16 of strap clamp layer, and little the lower left quarter of heating mantles 16 inserts a blast pipe 6 to big down from last in its cross section, and the jet pipe 20 on cover top (can establish 4 to 8, decide on the cylindrical shell size) passes ventilating board 3, is distributed on the bottom of pulverizing chamber 2.A plurality of spray orifices are being arranged on the top of jet pipe 20.Rotating shaft vertically is arranged in the middle of the equal greenhouse 4, and the axle middle part is welded with the flight 14 that one group of external diameter enlarges gradually.All 4 bottoms, greenhouse lead directly to separation chamber 8, and ring-shaped air chamber 5 usefulness one separating plate 7 on separation chamber 8 and its top separates, and has the multi-turn aperture on the plate.Exhaust outlet 18 is located at the upper right side of ring-shaped air chamber 5, and discharging opening 10 then is located at the bottom of separation chamber 7.Separation chamber 8 is passed in rotating shaft 12, and a sealing mechanism 13 is arranged therebetween.

Characteristics of the present utility model are: 1, the opposite at a high speed double rotary wheel that rotates is pulverized paste material efficient height; 2, hot blast utilization rate height heated cover before this, made equal hot cell keep samming, sprayed into pulverizing chamber again, the convection drying material; 3, the flight that rotates at a high speed makes material separate from air-flow, makes this device be achieved gas solid separation; 4, rate of drying is exceedingly fast, and general needs several seconds kind time, and the material for wet especially needs tens seconds at most.

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

The number in the figure explanation:

1-charge pipe, 2-pulverizing chamber, 3-ventilating board

4-all greenhouse 5-ring-shaped air chamber, 6-blast pipes

7-separating plate, 8-separation chamber, 9-push-pull valve

10-discharging opening 11-following motor 12-rotating shaft

13-sealing mechanism, 14-flight, 15-cylindrical shell

16-heating mantles, 17-thermocouple, 18-exhaust outlet

19-following spinning roller 20-jet pipe 21-last spinning roller

22-upward motors

See also accompanying drawing, start upper and lower motor 11,22, upper and

lower spinning roller

19,21 begins to rotate, hot blast is fed blast pipe 6, after treating that equal greenhouse reaches design temperature, promptly in charge pipe 1, add paste material, in material one enters pulverizing chamber 2, promptly smashed by the upper and

lower spinning roller

19,21 of phase embedding each other.(we can say that paste material can hide between four groups of rods that rotate at a high speed nowhere, it can only be broken.) meanwhile thermal current constantly from the spray orifice of jet pipe 20, spray, heat pulverized paste material; Be accompanied by the evaporation of moisture content in the material, the material that is dried dwindles gradually.Very fast material is taken in the middle of the pulverizing chamber 2 by thermal current, and the air vent that passes on the ventilating board 3 with air-flow enters equal greenhouse 4.4 li small particles materials continue to be heated in equal greenhouse, moisture content further obtains evaporation in the material, material obtains further drying, under the effect of bottom flight 14, the flight 14 that material particles is rotated at a high speed gets rid of the barrel to separation chamber 8, and falls down to discharging opening 10 along wall, and air-flow then passes the intensive aperture from separating plate 7, along ring-shaped air chamber 5, up discharge from exhaust outlet 18.Material is from adding, and discharge dry back, the time compole short, generally only need several seconds.

This device is applicable to the paste material drying of chemical industry, medicine, food, biology, light industry, also can handle simultaneously the drying operation of graininess, filter and materials such as shape and muddy, because its collection material pulverizes, dry, be located away from one, so it be a kind of be worthy to be popularized efficiently, drying device fast.
