Description
Technical field
The utility model relates to material collecting device under the tower of urea high-tower granulation device and Chemical Mixed Fertilizer high-tower granulation device,More specifically, the utility model relates to scraper at the bottom of a kind of high-tower granulation device tower.
Background technology
In current high tower fused melt granulated device, the rewinding mode of granulation tower bottom has cantilevered scraper, VShape recovering hopper, W shape recovering hopper and disc type scraper, this several rewinding modes are in high tower fused melt granulated devicePractical operation situation is analyzed as follows.
Cantilevered scraper
Cantilevered scraper is mounted in granulation tower bottom with on the taper concrete bucket of 15 °～18 °, passesMoving device is arranged on the beneath necromancer of cone bucket cone and builds on pre-buried bolt, by the cantilever above transmission device band mantle bucketRotate, the angled scraper plate of some tools distributing on cantilever rotates and fertilizer was progressively scraped to tower by tower week with cantileverCenter blanking place;
Because cantilever is fixed and drives cantilever to rotate by boring bucket central pivot point, other is located without fulcrum, and cantilever is strongDegree can not do again too much, and it is excessive that the intensity of cantilever is done the operating load that will make too much, and power consumption increases; ShouldAfter device running a period of time, due to wet stickiness and the caking of materials at bottom of tower, cause cantilever resistance to increase, causeCantilever upwarps, and makes the distance between cantilever and the upper surface of cone bucket increasing, and the bed of material on cone bucket is more more long-pendingThick, cause and the moisture absorption water of the bed of material cause environmental pollution and fertilizer loss. The cantilever of scraper can stick material, andMore glutinous more, being accumulate to a certain degree just can Automatic-falling, and the bulk coming off is easy to feed opening being blocked, nowMust stop and process. Cantilevered scraper cost is high, and power consumption is large.
V-arrangement recovering hopper shortcoming
The setting height(from bottom) of V-arrangement recovering hopper is higher, taking Φ 18000mm granulation tower tower diameter as example, V-arrangement recovering hopperMaximum absolute altitude, at the 15000mm place of granulation tower cylindrical shell, reduces the effective depth of tower. If comminutor rotating speedIt is improper to control, and the buildup of V-arrangement recovering hopper can get more and more, and generally move 2 months and need the cleaning of stopping, otherwiseCan press the V-arrangement recovering hopper that collapses, and cleaning difficulty is large, dangerous.
W shape recovering hopper
W shape recovering hopper is to develop on the basis of V-arrangement recovering hopper, is configured to several rectangular V with steelShape recovering hopper, section is W shape, and each V-arrangement recovering hopper is divided into 1 finished product rewinding belt. W shape recovering hopperBucket number increases along with the increase of granulation tower diameter, is generally 2～6 buckets. Compared with V-arrangement recovering hopper, W shapeThe height of recovering hopper reduces about 9000mm, has saved capital expenditure. Buildup, the glutinous material of W shape recovering hopper are comparativelyGeneral problem, although numerous enterprises and designing unit have taked multiple coping style, thoroughly separates so far not yetCertainly, the scar piece of clearing up still needs again broken rear retrieval system digestion process. W shape recovering hopper bottomFinished product outfeed belt has material to scatter, and the fertilizer per tour scattering on the ground all needs timely cleaning, particularly in the summerIn season, if cleaning will the moisture absorption be dissolved not in time, cause loss and the environmental pollution of fertilizer. When belt feeder runningThe black rubber wearing and tearing can affect the outward appearance of fertilizer, and summer is particularly serious.
Disc type scraper
As Chinese patent CN103394306A discloses scraper in the disk for collecting material of a kind of compound fertilizer granulating high tower bottomMachine, this utility model is that the flat disk for collecting material of a kind of Dai of rotation center blanking hole is installed at the bottom of high tower tower, is receivingOn material disk, the conveying worm that 2-3 platform rotates is installed, the driving end of conveying worm is fixedly mounted on tower wallPlace, the other end of conveying worm is fixedly mounted on the central hole of disk, and conveying worm is not with disk for collecting materialRotate, when the material on disk for collecting material turns to conveying worm place, by the rotation of conveying worm, processMaterial scraper on the disk at conveying worm place is to disc centre, completes the process of rewinding at the bottom of tower; This utility modelWeak point be, rewinding is flat disk rewinding, causes conveying worm load large, particle is many; Spiral transferringSend the disk that machine and high tower base diameter are larger to rotate simultaneously, need power larger; At the bottom of tower, need do more basis andMore tugboat is installed, to support the disk of larger rotation, mechanism's complexity, tower base space is occupied, at the bottom of towerMaintenance and cleaning are inconvenient.
As Chinese patent CN204469663U discloses pivoted arm scraper at the bottom of a kind of high tower compound fertilizer tower, its spyLevy and be, comprise the rewinding face and the pivoted arm scraping mechanism that are arranged on high tower bottom, rewinding face top is pivoted armScraping mechanism, the below of pivoted arm scraping mechanism is provided with taper recovering hopper, and rewinding face center is connected with tremie pipe,The outer cover of tremie pipe has gear wheel, and a side of gear wheel has the pinion being engaged with, pinion and engineStructure connects; Gear wheel is connected with pivoted arm scraping mechanism. This device exists only has cone bucket central pivot point to fix, itsIt is located without fulcrum, and that the intensity of cantilever can not be done is too much; Therefore this device turned round after a period of time, meetingCause that cantilever upwarps, make the distance between cantilever and the upper surface of cone bucket increasing, the bed of material on cone bucket moreLong-pending thicker, cause and the moisture absorption water of the bed of material cause environmental pollution and fertilizer loss; The pivoted arm of pivoted arm scraperCan glutinously expect, and more glutinous more, every the processing of need not stopping for a long time; This apparatus cost is high, and power consumption is large.
Several rewinding modes, in the one-sided function of strengthening, have caused the weakening of other function above, and generalAll over there being the problem that investment is high, power consumption is high.
