Description
A kind of twin shaft reverse-flow type heating stirring drier.
The utility model belongs to the drying equipment technical field.
A large amount of drying machines that use are cylindrical drier and rake type drier in the industrial production now, 89211382 patent rotating disc type heat drying machines design for the shortcoming that overcomes cylindrical drier, 89203837 patent dismountable plate types heating agitated dryer designs for the shortcoming that overcomes rake type drier, and the board-like stirring drier of the fixing heating of 92242617 patents designs for the shortcoming that overcomes 89203837 patent dismountable plate types heating agitated dryer.The drying machine that uses in now producing and the general structure of above-mentioned three patents are single-shaft configuration, and the dry, flowable of material relies on rotating and reverse of motorized speed reducer, is stirred the scraper pusher, vertically, to the left or to the right, and unidirectional propelling, shuttle flowing.The material that is pulled to left end or right-hand member is excessive extrusion often, and it is inhomogeneous to cause material to be heated easily, and uneven drying is even.The shell body of single shaft drying machine is the cylinder tubular construction, improves the essential dilated diameter of material capacity, and the arm of force that therefore stirs the scraper pusher is long, and is stressed big, damages easily.What the motorized speed reducer of single shaft drying machine was frequent periodically rotated and reverse in 1～2 minute, therefore improved the drying machine speed of mainshaft and was restricted, and can only reach about 8 rev/mins.Main shaft slow-speed of revolution operating mode makes material the be heated increase of chance and the further raising of equipment thermal efficiency, all is restricted.The main shaft slow-speed of revolution and discontinuous intermittent running operating mode also are restricted further boosting productivity.What motorized speed reducer was frequent rotates and reverse, the discontinuous running operating mode, and shorten service life.
The purpose of this utility model is, breaks through single-shaft configuration, and the drying machine of the two main axle structures of design overcomes above-mentioned single-shaft configuration problem that be difficult to solve, each side, keeps the part advantage of single-shaft configuration simultaneously.
Task of the present utility model is achieved through the following technical solutions, drying machine is made up of motorized speed reducer (1), yielding coupling (2), left end bearing and bearing block (3), stuffing box (7), middle heating plate (11), middle scraper pusher (12), right-hand member bearing shaft bearing stuffing box assembly (15), the upper shell (10) etc. of stirring, it is characterized in that two main shafts of device in the lower house (9), driving shaft (18), driven shaft (19), a pair of gear (4,5) transmission by axle head, switched in opposite has identical stirring scraper pusher on two main shafts.Middle stirring scraper pusher (12) has 10～18, the center line of its axial material scraping plate (22), with the center line angle of main shaft (18) be 15 °～20 °, promote the material axial flow, the center line of the axial material scraping plate (22) of the stirring scraper pusher (13) of left and right end, with the center line angle of main shaft (18) be 0 °, promote the material Radial Flow, thereby reach flowing of material, form continuous reflux state.Therefore, material is heated and the uniform drying degree improves, and product quality further improves.Stir scraper pusher (12,13), by radially material scraping plate (21) and axially material scraping plate (22) composition.Axially material scraping plate except striking off the material that sticks on the inner walls, also has and disperses and the pusher function.Material scraping plate (21) radially, except striking off the material that sticks on the heating plate, also has agitating function, its geometry, can use two sides to be processed into the trapezoidal plate on 15 °～30 ° of inclined-planes, to reduce the scraper resistance: the resistance according to different materials and minimizing scraper, also can use pole or semicylinder etc. radially to stir and scrape charge bar.Two main axle structures, overcome the single-shaft configuration motorized speed reducer frequent fall, clockwise and intermittent running operating mode, and therefore can be the speed of mainshaft by about 8 rev/mins, be increased to about 30 rev/mins, increased be heated chance and improved device heat efficiency of material, improved production efficiency simultaneously, and the service life that has prolonged motorized speed reducer.Compare with single shaft single cylindrical cylinder shell, the utility model uses after the lower house of two main shafts and bicylindrical double shell, not only the arm of force that stirs the scraper pusher is shortened 2/5ths, thereby reduced because stir the damage of scraper pusher, and the stop production to overhaul that causes loss.And, owing to stir the contraction in length 2/5ths of the radially material scraping plate (21) of scraper pusher, be decreased to 15 °～20 ° with the angle of axial material scraping plate (22) and main shaft, the pitch that is made of them also just reduces, therefore in the material propelling movement process vertically, the mobile uniform and stable more of material dispersed, material and the stressed excessive possibility of stirring scraper pusher further reduce, and production efficiency does not only reduce, but because the raising of two main axle structure speeds of mainshaft, production efficiency is improved 2～4 times, and this is that single main axle structure can't be realized technically.In other words, single main axle structure reduces the pitch that stirs the scraper pusher, is subjected to the restriction of various factors, and two main axle structure uses after the fine pitch, and not only production efficiency can not reduce, and can also enhance productivity 2～4 times.Compare with the single shaft drying machine, the utility model upper shell (10) has increased heating jacket (24), makes the evaporation steam in the drying machine, is difficult for being condensed into the globule and drips in people's material.Steam or low boiling point solvent enter drying machine by import (25), through last chuck (24), following chuck (23), middle heating plate (11), left and right end heating plate (14), after giving the material that is dried heat energy, by be arranged on the same horizontal plane of import (25) on outlet (26) discharge.
The utility model compared with prior art, the advantage that has is, the increase of single shaft drying machine cylindrical shell diameter is subjected to the various factors restriction, and is long as stirring the scraper pusher arm of force, damage easily.The heating plate reliability of fixation reduces in the course of the work, and the possibility of distortion increases.The drying machine vibration is big, the steel waste of upper shell nonuseable part, and making difficulty of processing increases or the like.Steel are not only saved in the design of the two main shaft double shell lower house drying machines of the utility model, reduce difficulty of processing, improve the reliability of equipment, durability.Also reduce user's investment, improved device heat efficiency and production efficiency, improved the dry mass of material.
