Bale breaker
Technical field
The present invention relates to the production equipment of composite fertilizer, particularly relate to a kind of bale breaker.
Background technology
Caking is that material transfers a kind of character of agglomerate or entirety to from loose condition (of surface).It is generally acknowledged that the caking of fertilizer is caused by its inner character, formed by the contact point of particle.The mechanism that caking produces is very complicated, mainly contains brilliant bridge theory at present, capillary attraction is theoretical, chemical action is theoretical and plastic deformation theory.Brilliant bridge theory is thought because oneself factor is as the geometry etc. of the character of material, chemical composition, granularity, size distribution and object, with the change of extraneous factor as humidity, temperature, pressure and impurity etc., due to the existence of moisture in object, body surface is dissolved and is recrystallized, thus contacting with each other a little between crystal grain forms brilliant bridge, As time goes on, make die bonder together, form huge agglomerate gradually.Capillary attraction theory is thought, due to the existence of capillary attraction power between fine-grain, makes the saturated vapor pressure on capillary meniscus lower than the saturated vapor pressure of outside, and this just causes condition for steam to intercrystalline diffusion; There is hygroscopic fertilizer more than its critical relative moisture, absorb moisture, the saturated solution film of fertilizer is formed at plane of crystal, this solution film accelerates capillary absorption, the meniscus that surface tension is formed makes ion move to particle contacts place, causes being formed crosslinked between adjacent particle and being bonded to agglomerate.Chemical action theory then thinks that chemical fertilizer can not complete reaction in granulation process, can continue react and generate double salt in storage process, and results of these reactions will cause recrystallization and lump.Plastic deformation theory thinks fertilizer agglomeration all along with deformation, and this deformation can aggravate due to pressurized, and the chemical fertilizer residual heat without thoroughly cooling outwards shifts from granular center, if at this moment chemical fertilizer granule is squeezed and just can causes deformation, and then lumps.Caking causes primarily of following reason: (1) product water content moisture is higher, and intergranular salt dissolves and more easily carries out with crystallization process, more easily lumps.(2) package temperature package temperature is high, and interiors of products moisture could not fully discharge, and easily lumps; Product temperature is low, easily from air, absorbs moisture, also easily lumps.(3) storage pressure fertiliser granulates is under weight, and particle contacts is tightr, particles deform, and contact surface increases, thus causes caking.(4) also can continue in storage time fertilizer product a period of time after packaging certain reaction occurs, as moisture absorption, dissolving, recrystallization, the double decomposition etc. between salt, this process duration is very long, so the storage time is more of a specified duration, lumps more serious.(5) the little and out-of-shape of the shaped particles of particle, multi-angular, specific area is greatly more easily lumpd.(6) uniformity of particle and hardness particle uneven, then contact area increases; Hardness is low, then easily crush, and causes contact area to increase, easily lumps.(7) the impurity composition that intragranular impurity forms and content is different can affect saline crystallization degree and crystalline particle size, thus affects degree of agglomeration.
Except attention overcomes except above-mentioned influence factor in fertilizer production, in fertilizer, add anticaking agent is a kind of way alleviating caking.Anticaking agent conventional at present has inert powder, inorganic salts, surfactant and non-Surfactant.Processing cost per ton is up to 15-30 unit, although add high expense, also difficulty or ease solve completely.Often there will be product caking, and the product of caking need be done over again, and causes cost increase, or artificial bale breaking, labour intensity is large.

Wherein in an embodiment, the bolt hole of described second running roller two side shaft holder is elongate holes.
Wherein in an embodiment, described first running roller, the second running roller are equipped with and severally roll bar support ring, described in roll even first running roller of bar support ring, the second running roller, described in roll bar be connected to described in roll bar support ring.
Wherein in an embodiment, the described bar that rolls is seamless steel pipe, its length and described first running roller length, the second running roller length are consistent, described in roll bar be uniformly distributed in described in roll bar support ring, and described first running roller rolls bar, the second running roller rolls the distribution of bar mutual dislocation.
Wherein in an embodiment, described in roll outside bar and be provided with rubber layer.
Above-mentioned bale breaker, first running roller, the second running roller and the design of rolling bar make the block chemical fertilizer in packaging bag broken, do not need adopt artificial bale breaking or do over again, thus avoid labour intensity greatly, costly, avoid caking fertilizer all to do over again, reach and do not damage outer packaging bag, save labour, cost-effective object.
The radius size of above-mentioned bale breaker first running roller is consistent with the radius size of the second running roller, the radius size of described first travelling gear is consistent with the radius size of the second travelling gear, and described first travelling gear radius size is greater than the first running roller radius size and with the design of the diameter dimension sum of rolling bar, packaging bag is conveniently entered.
The radius of addendum of the first travelling gear described in above-mentioned bale breaker and the difference of root radius, the radius of addendum of the second travelling gear and the difference of root radius are that the design of 60mm or more and the bolt hole of described second running roller two side shaft holder are elongate holes design the second running roller can be moved, and can regulate spacing between the first running roller, the second running roller according to the size of packaging bag.
