Description
Technical field
The utility model belongs to dry mortar making equipment technical field, particularly relates to a kind of dry powder and mortar dryer.
Background technology
At present, produce in the process of dry powder and mortar, the oven dry of sand is one important operation, in the drying course of sand, mostly adopt roller dryer, drum-type drying operation principle be cylinder sand being entered dryer from charging aperture, along with the rotation of cylinder, in cylinder, be blown into the air of heating, the moisture contained by sand is taken away, and reaches the object of drying sand; The rotation of cylinder is under dynamic action, and drive the follower on cylinder by driving wheel thus make cylinder produce rotary motion, the power of driving wheel is that motor passes to driving wheel through transmission device again by decelerator.
Tradition dryer feeding device many employings blanking scraper-trough conveyer, is arranged on fluidized bed furnace air outlet top, because fluidized bed furnace air outlet flue-gas temperature is higher, even if tremie pipe adopts casting heat resistant steel, it sees that fiery position is also easy to be burned, and changes frequent, has had a strong impact on the normal operation of dryer.For the material that mobility is poor especially, as coal slime, flyash and gypsum etc., also easily there is putty phenomenon in blanking scraper-trough conveyer.Minority producer is for avoiding putty phenomenon, and adopt conveying worm to feeding in stove, this technique disadvantage is more, as feeding process is arranged loaded down with trivial details; Conveying worm heating end bearing is fragile; Body of heater interface thermal loss is comparatively large, conveying capacity is restricted., all there is application limitation and maintenance hidden danger, reduce the running rate of dryer in the above two kinds of technique.
Summary of the invention
The problems such as the utility model provides a kind of dry powder and mortar dryer, proposes existing traditional dryer there is application limitation and maintenance hidden danger to solve in above-mentioned background technology, and the running rate of dryer is low.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of dry powder and mortar dryer, it is characterized in that: comprise fluidized bed furnace air outlet, fume pipe, end flanges, spiral propeller, welding portion, drying machine drum, motor A, motor B, support roller A, support roller B, bearing, one end of described fume pipe connects fluidized bed furnace air outlet, other end connecting end surface flange, its outside is provided with fume pipe inwall, its inside is provided with observation panel, described end flanges another side connects spiral propeller, the upside of described spiral propeller is provided with charging aperture, inside is provided with feed box, rotating vane, the equally distributed axis gripper shoe of axis, be arranged with static seal device and dynamic sealing device outward, one end and the drying machine drum of described feed box weld together, described static seal device side is provided with front wheel belt, motor A is provided with below described front wheel belt, described motor A side is provided with support roller A, the another side of described support roller A is provided with control device, described control device another side is provided with support roller B, bearing is provided with below it, described support roller B another side is provided with motor B, rear wheel belt is provided with between the periphery of described drying machine drum and motor B, the upside of described drying machine drum is provided with humidity sensor.
In described fume pipe inwall, welding dog, re-lays the alumina silicate felt that one deck 50mm is thick.
Described rotating vane adopts wear-resisting steel plate to make.
Described axis gripper shoe is in the outside of rotating vane.
The beneficial effects of the utility model are:
In 1 this patent, because spiral propeller front end directly contacts (design temperature 800--1000 herein with thermal-flame
oc), under high temperature action, intensity reduces, and easily forms the situation of breach and weld cracking; Therefore, front end have employed end flanges structure, avoids thermal-flame directly to rush burning helical blade, also plays the effect of backgauge.
2 this patents are in selection, rotating vane welds with spatial skeleton and adopts the EDMn type Hadfield steel welding rod close with cylinder material, weld need offer groove, weld bead height is not less than 10ram, surrounding symmetric position two people welding simultaneously, and after completing, roundness tolerance should control at 5-8ram, avoids welding deformation.
3 this patent dry powder and mortar dryer devices, avoid the situation that blanking is not smooth, pan feeding is uneven, enhance the decentralization of material and the uniformity of feeding.Feed box and spiral propeller adopt appropriate matched in clearance, and under normal running conditions, material forms stable bed course at feed box inwall, avoids the generation of abrasion condition.Because feed arrangement instead of the collet structure of traditional dryer, make thermal source circulating resistance less, material can be made to be subject to preheating earlier, be widely used, significantly improve drying effect and running rate.
In 4 this patents, after working long hours, the mosaic fissure between feed box and drying machine drum easily produces Lou expects, causes and dries machine room dust pollution comparatively greatly, affect working environment.The combination that we adopt targetedly " axial labyrinth+fish scale sealing ", namely on cylindrical shell, labyrinth movable sealing is set with, static seal is connected with feed box by flange, static seal divides upper and lower body structure, in order to enhanced leaktightness effect, be provided with fish scale sealing installation position at the afterbody of dynamic and static sealing, slow down the wearing and tearing of flap, thus improve service life and sealing effectiveness, reduce maintenance hidden danger.
The spiral propeller of 5 this patents adopts heat-resisting, wear-resisting steel plate making, when observing service condition by fume pipe fire door, find no the situation that obvious temperature distortion and weld seam snap, the lopsided wear that just helical blade marginal existence is slight, substantially reduces because of dryer plant failure and the situation of stop production to overhaul.
Its result of use of the Reliability Assurance of the structural design of the dryer of 6 this patents, improve 10%-20% during more traditional oven dry board, daily zero dimension is protected, and service life increases greatly.
7 this patent drying machine drums are provided with Temperature Humidity Sensor, effectively can observe the oven dry situation in dryer, and convenient operation person operates, and is also provided with control device, can realizes automation drying effect.
