Abstract
The utility model discloses the structure of a combined type screw dryer, which comprises screw conveyors, material conveying cylinders and heating sleeves, wherein, the two material conveying cylinders are arranged up and down in parallel and are communicated, and the two screw conveyors are respectively arranged in the material conveying cylinders. Helical blades and crushing teeth are arranged on the screw conveyors, and the heating sleeves are sheathed outside the material conveying cylinders. A shaft of a speed adjusting motor is connected with a shaft of the lower screw conveyor, and the upper screw conveyor is driven by the speed adjusting motor through a chain wheel. The combined type screw dryer has the advantages of simple structure, low energy consumption, high heat utilization ratio and favorable drying effect. The combined type screw dryer is suitable for drying granular materials and powder materials and can also dry paste materials.
Description
The utility model relates to the drying device of removing liquid from solid material, and specifically a kind of helical blade by rotation promotes discrete material and carries out dry combined type spiral dryer, includes auger conveyor, mass transport tube and heating muff.
A kind of single shaft downflow type blade drying machine that uses carries out drying to discrete material at present, because the space is less in the body, it is generally shorter that axial length is subjected to process limitation, thereby cause the dry heat air pressure height of using, flow velocity is big, cause this drying machine energy consumption big, heat utilization ratio is low, the dry materials weak effect.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, discloses a kind of structure of combined type spiral dryer, and is simple in structure, can cut down the consumption of energy, improve heat utilization ratio, drying effect is good, can be fit to the drying of graininess and powder material, also can carry out drying to plaster material.
The utility model combined type spiral dryer, include auger conveyor, mass transport tube and heating muff, the technical measures that realize the utility model purpose are: two parallel going to upper and lower of mass transport tube are disposed and connection, article two, auger conveyor places respectively in the mass transport tube, auger conveyor is provided with helical blade and crushing teeth, heating muff is sleeved on outside the mass transport tube, goes up auger conveyor with the buncher of following auger conveyor shaft coupling by the drive sprocket driving.
The utility model combined type spiral dryer is in two mass transport tubes that are communicated with auger conveyor to be set respectively, technology process for drying material has extended, the auger conveyor that has shortened relatively, bigger space is arranged in the favourable body, buncher is by auger conveyor on the chain wheel drive, can make two auger conveyors obtain different rotating speeds, favourable raising heat utilization ratio and obtain preferable drying effect, crushing teeth is set on the auger conveyor, broken material conglomeration in dry run (particularly plaster material), favourable conveying and drying.Heating muff is sleeved on outside the mass transport tube, in heating muff, feed waste heat of plant hot gas (as waste hot gas, flue gas etc.) and can carry out indirect the material that is dried in the mass transport tube, only need the wet branch that evaporates after a small amount of hot gas belongings material indirect in the mass transport tube, both fully utilize the energy, significantly reduced hot gas consumption than prior art again.In sum, the structure of the utility model combined type spiral dryer has realized the purpose of this utility model preferably.
Below in conjunction with accompanying drawing the utility model and embodiment are described further.
Accompanying drawing is the structural representation of an embodiment of the utility model combined type spiral dryer.
As an embodiment of the present utility model, as shown in drawings, include auger conveyor, material conveyer and heating muff, article two, mass transport tube 3,3a is parallel to be presented, following configuration also is communicated with, article two, auger conveyor 4,4a places mass transport tube 3 respectively, in the 3a, at auger conveyor 4,4a is provided with helical blade 7 and crushing teeth 6, heating muff 5 is sleeved on mass transport tube 3, outside the 3a, for reducing thermal loss, heating muff 5 outer walls preferably are incubated processing, go up helical wheel with the buncher 11 of following auger conveyor 4a shaft coupling by drive sprocket 9 drivings and send device 4.During drying operation, waste heat hot gas feeds in the heating muff 5 from waste hot air air inlet 8, air inlet 8a in the middle of gas outlet 12a and heating muff in the middle of the heating muff of butt joint, 12 discharges from the waste hot air gas outlet at last; Material to be dried is sent in the mass transport tube 3 from the charging aperture 1 of last mass transport tube 3, under the helical blade on the last auger conveyor 47 promotes and tooth 6 fragmentations that are broken, middle blanking port 10a and intermediate feed mouth 1a through butt joint, material enters down mass transport tube 3a, discharges from blanking port 10 at last; A small amount of saturated hot gas is sent in mass transport tube 3, the 3a from saturated hot air intake 2, carries that material is heated the wet branch that evaporates by heating between hot gas in the sleeve 5 in the material transport tube 3,3a.Actual requirement according to the character and the drought index of material to be dried, the utility model combined type spiral dryer can thereunder be connected in series combination one group of (as shown in drawings) or one group of this above combined type spiral dryer, simple in structure, the heat utilization ratio height, drying effect is good.
Claims (2)
