Abstract
The utility model discloses a rotary multi-cylinder dryer and belongs to drying equipment. The rotary multi-cylinder dryer comprises an outer cylinder body, two backing rings and a gear ring, wherein the outer cylinder body is provided with a feed inlet and a discharge outlet, the backing rinds and the gear ring are arranged on the outer wall of the outer cylinder body, the gear ring is arranged between the two backing rings, and a backing wheel is arranged below each backing ring in a matched mode. A gear is arranged below the gear ring, and the gear is meshed with the gear ring. A motor drives the gear through a transmission. A plurality of inner cylinder bodies are evenly arranged in the outer cylinder body, wherein the outer surface of each inner cylinder body is internally tangent with the inner surface of the outer cylinder body, and outer surfaces of adjacent inner cylinder bodies are externally tangent. Two ends of each inner cylinder body are fixed through sealing plates, and periphery edges of the sealing plates are fixed on the inner wall of the outer cylinder body in a sealing mode. The rotary multi-cylinder dryer is suitable for production of granular fertilizer. Compared with a traditional single-cylinder dryer, the rate of finished products of the fertilizer can be improved by 20% - 30%.
Description
Technical field
The utility model relates to a kind of drying plant, specifically, relates to a kind of swinging multi-drum drier.
Background technology
Traditional rotary dryer is because it only has a Drying, so be called again the monotubular dryer.Its drying course is: after wet feed entered Drying, along with the rotation of cylindrical shell, lifting blade swept to the upper end of cylindrical shell from cylinder body bottom and falls in cylinder, is then kicked up again, repeatedly more than hundred times; Because cylindrical shell is equipped with the inclination angle, the motion of the on-stream generation of material from feed end to discharge end, hot blast passes through along flow direction of material or contrary flow direction of material in motion process, thereby reaches the purpose of material drying.
Because the monotubular dryer is a kind of universal dryer, be difficult to guarantee that graininess fertilizer (particularly outlet is fertile) product reaches that outward appearance is good, epigranular, chip index is low, intensity is high, moisture content is low etc. requirement, so be not suitable for the oven dry of graininess fertilizer.Concrete reason is as follows: wet granulated fertilizer to be dried after the balling-up, and moisture content is higher, and when it entered Drying, repeatedly from the high-end low side of falling of cylindrical shell, because the initial strength of particle is low, easily generation mutually was bonded to piece or destroys from the profile of comminutor out the time; Qualified product runs to the posterior segment of cylindrical shell even if the part granularity is arranged, but through continuous falling repeatedly, still can cause appearance poor unavoidably, and powder is many, intensity difference, and yield rate is low.
Summary of the invention
The technical problems to be solved in the utility model is to overcome defects, and a kind of oven dry that is applicable to graininess fertilizer is provided, and can improve the swinging multi-drum drier of graininess fertilizer yield rate.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of swinging multi-drum drier, comprise the outer cylinder body that is provided with charging aperture and discharging opening, be located at two backing rings and gear ring on the outer cylinder body outer wall, gear ring is located between two backing rings, the below correspondence of backing ring is provided with the support roller that is complementary, the below of gear ring is provided with gear, gear is meshed with gear ring, motor is by the speed changer travelling gear, it is characterized in that: evenly be provided with several inner barrels in the described outer cylinder body, the inner surface phase inscribe of the outer surface of each inner barrel and described outer cylinder body, mutually circumscribed between the outer surface of adjacent inner barrel; The two ends of each inner barrel are fixed by sealing plate respectively, and the neighboring sealing of sealing plate is fixed on the inwall of outer cylinder body.
Say further, be evenly distributed with lifting blade on the inwall of described each inner barrel posterior segment.
Furtherly, be provided with the cone of gathering materials between the front port of the charging aperture of described outer cylinder body and each inner barrel.
Owing to adopted technique scheme, the utility model is applicable in the production of the graininess fertilizer such as granular calcium magnesium-phosphorus fertilizer, granular compound fertilizer, graininess calcium superphosphate, graininess coarse whiting, graininess phosphoric acid di-calcium, compare with traditional monotubular dryer, the yield rate of fertilizer can improve 20%-30%.In addition, the utility model also has the following advantages:
1, because the whole grain effect that the inner barrel front end has can make bead and powder second balling-up, make finished particle Paint Gloss mellow and full, intensity is higher, thereby has reduced the use amount of adhesive, has increased active ingredient, has reduced manufacturing cost.
2, the structure of many of dryers, biography (storage) hot side that has made it to increase by 1 times is long-pending, and reasonably utilizes leading portion high-temperature region and material high humidity section in the machine, obtains best thermal conduction effect, overall efficiency height, Heat stability is good.
3, because outer cylinder body is not frayed, inner barrel easy to wear is also easily changed, thereby has prolonged exponentially the service life of whole equipment.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
Embodiment:
With reference to Fig. 1, Fig. 2, swinging multi-drum drier described in the utility model, comprise the outer cylinder body 2 that is provided with charging aperture 1 and discharging opening, be located at two backing rings 3 and gear ring 4 on outer cylinder body 2 outer walls, gear ring 4 is located between two backing rings 3, the below correspondence of backing ring is provided with the support roller 6 that is complementary, the below of gear ring 4 is provided with gear, and gear is meshed with gear ring 4, and motor 8 is by speed changer 7 travelling gears.Described outer cylinder body 2 interior several inner barrels 5 that evenly are provided with, present embodiment is preferably 6 inner barrels 5, is evenly distributed with lifting blade 11 on the inwall of described each inner barrel 5 posterior segments.The inner surface phase inscribe of the outer surface of each inner barrel 5 and described outer cylinder body 2, mutually circumscribed between the outer surface of adjacent inner barrel 5.The two ends of each inner barrel 5 are fixing by sealing plate 10 respectively, and the neighboring sealing of sealing plate 10 is fixed on the inwall of outer cylinder body 2.
Be provided with the cone 9 of gathering materials between the charging aperture 1 of described outer cylinder body 2 and the front port of each inner barrel 5.
The course of work of the described swinging multi-drum drier of present embodiment is summarized as follows:
8, six inner barrels of actuating motor 5 and outer cylinder body 2 synchronous rotaries.Direct Uniform ground enters in each inner barrel 5 the graininess wet feed after the cone 9 through gathering materials, and after inner barrel 5 Inner Front Ends again carry out whole (being equivalent to 6 little rotary drum granulator functions), obtain certain initial strength, is kicked up by lifting blade 11 in the posterior segment.Hot gas enters each inner barrel 5 and heats each inner barrel 5 from charging aperture 1, the deposit heat.Material moves to the process of discharge end at the front end from inner barrel, absorbs the heat of inner barrel 5 and the heat that hot gas directly conducts, and reaches stable, even oven dry.
