Abstract
The invention relates to a self-grinding device of a lump in a rotary drum granulator. The self-grinding device comprises a fragment screening mesh which is connected to a discharge end of the rotary drum granulator; the fragment screening mesh is completely coated on a port of the discharge end of the rotary drum granulator; and a plurality of fragment screening strips are coaxially, concentrically and evenly connected to the outer circumference of the granulator at intervals to form the fragment screening mesh, so as to achieve self-grinding of the lump of the granulator. The self-grinding device is simple in structure, low in production cost, low in artificial labor intensity, stable in production technology and high in rotate rate; a power source and equipment do not need to be added; the energy is saved and consumption is reduced; and the granulating output and the granulating quality are improved.
Description
Technical field
The present invention relates to composite fertilizer, mix fertile production technical field, is that the interior piece group of a kind of rotary drum granulator is from crushing device specifically.
Background technology
In compound, mixed fertile prilling production process, except producing particle up to specification, also be easy to generate the higher piece group of some moisture content, in follow-up drying course, internal moisture is not easy evaporation and shifts out, often cause the screening plant of postorder easily to produce paste sieve, disintegrating apparatus obstruction, thereby cause system shutdown, influence operating efficiency and product quality.If raising bake out temperature, then increased energy consumption, roundness and the surface flatness of qualified particle have been destroyed, not only reduced the product appearance quality, and lump after causing finished product packing, and the higher piece group of intensity easily causes equipment attrition after entering disintegrating apparatus, both increased the equipment operating cost, increase production cost, brought negative effect to market sale again.
Summary of the invention
Piece group compound in order to solve, that produce when mixing fertile granulation is to the influence of product quality; cause energy consumption to rise; equipment stops up and damages; the worker leads, productive rate is low; defectives such as poor product quality; the invention provides a kind of simple in structurely, easy to use, can effectively reduce the granulation energy consumption, increase work efficiency, in the rotary drum granulator of product yield, product quality, service life of equipment and production safety performance piece group from crushing device.
The technical solution used in the present invention is: piece group is from crushing device in a kind of rotary drum granulator, and its technical characterstic is to comprise the broken minute screen cloth that is connected the rotary drum granulator discharge end.
Further, described broken minute screen cloth coats rotary drum granulator discharge end port fully.
Further, screen cloth comprised many broken minute gratings in described broken minute, many broken minute gratings along rotary drum granulator axially and the parallel even interval of bulging comminutor discharging circumferencial direction that rotates be connected in rotary drum granulator discharge end port.
Further, screen cloth also comprised the end face baffle ring in described broken minute, and the end face baffle ring is connected in the outer end of many broken minute gratings.
Further, also comprise plenum chamber, the plenum chamber bottom is provided with the discharging of corresponding broken minute screen cloth and takes over, and the plenum chamber top is provided with the outgoing gas connection tube of corresponding broken minute screen cloth.
Further, described plenum chamber is provided with the manhole inspection door of corresponding broken minute screen cloth.
Again further, described plenum chamber is provided with the scraper cleaning mechanism, the scraper cleaning mechanism comprises rotating shaft, handle and wire brush, socket is arranged at the handle that plenum chamber is outer, drive the rotating shaft rotation in the rotating shaft, and socket is arranged in the plenum chamber, is the wire brush that breaks away from or be close to state by handle drives rotating shaft drive and broken minute screen cloth in the rotating shaft.
When rotary drum granulator rotates, under the effect of centrifugal force, frictional force, the piece group that intensity is not high, moisture content is higher is brought to and is bordering on highest point in the rotary drum granulator and falls, founder or strike on broken minute grating, part piece group bump is mutually also arranged simultaneously, bulk group falls and hits into fritter group, fritter group breaks into littler piece and grain into pieces, can pass through the broken minute gap between grating up to being broken into, be taken over by the discharging of plenum chamber bottom and discharge, reach the purpose of piece group autoclase; Before piece group was entering autoclase, qualified particle was discharged from the broken sub-sieve interspace of rotary drum granulator discharge end, and the piece group that falls from eminence can not smash qualified particle.
After adopting technical solution of the present invention, the beneficial effect that reaches is:
1, broken minute grating one end is welded on the rotary drum granulator discharge end circumference, need not to establish in addition bearing support, rotates with rotary drum granulator work, need not additional drives equipment, be conducive to save energy and reduce the cost;
2, broken minute grating can adopt with the garden steel and do, and guarantees that qualified particle can in time discharge when producing the rotary drum granulator discharge end at first and do not smashed;
3, broken minute grating connects the end face baffle ring outward, makes the end face baffle ring with general steel plate and can prevent that stops group flows out without autoclase, further guarantees the percentage of damage of piece group;
4, discharging take over be installed in broken minute grating under, guarantee that particle is not piled up and discharge rapidly; Outgoing gas connection tube is in time discharged tail gas generated by granulation, keeps granulation production environment cleaning; The manhole inspection door is convenient to personnel's maintenance of device interior;
5, wire brush by the handle drives rotating shaft along drum granulating machine drum body rotation direction direction; when buildup is sticky on broken minute grating, only need operating grip to drive wire brush by rotating shaft and contact with it, it is standby to treat to reset after the buildup cleaning again; in time broken minute screen cloth of cleaning is conducive to improve piece and rolls into a ball broken component efficiency.
The present invention is coaxial on the comminutor excircle, concentric evenly connects the autoclase that many broken minute gratings are formed broken minute screen cloth realization comminutor piece group at interval; it is simple in structure, need not power source and equipment increase; energy-saving and cost-reducing; production cost is low; hand labor intensity is low; stable processing technique, rate of rotation height, granulation output and granulation quality improve.
