Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of fertilizer production equipment, particularly a kind of internal return tablets press.
Background technology
The tradition spray granulation drier is outside returns technique, be sprayed on the fines of kiln hood returning charge through concentrated material by spray gun with (moisture 20%-30%), and take particulate as core through coating, bonding, fully contact with warm air from effects such as granulating and to make particle drying, dried work in-process rise on the screening plant through chapelet, macrobead is sent kiln hood as returning charge again granulation with screen underflow (particulate) by conveying belt through crusher in crushing, and qualified finished product packing dispatches from the factory.This technical process is longer, and returning charge amount large (being generally the 6-8 of output doubly), afterbody equipment are many, causes that energy consumption is large, efficient is low and environment is abominable.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for prior art, has proposed the internal return tablets press that a kind of energy consumption is little, efficient is high.
The purpose of this utility model can realize by following technical proposal: a kind of internal return tablets press is provided; comprise rotating cylinder; be arranged on the gas inlet chamber of rotating cylinder head; by the spray gun in the rotating cylinder head insertion rotating cylinder; be arranged on the main returning charge spiral on the rotating cylinder inwall; be arranged on the flight on the rotating cylinder inwall; be arranged on the classfied cone of rotating cylinder afterbody; the trommel screen that connects classfied cone; connect going out gas tank and being arranged on out crusher on the gas tank of trommel screen; be positioned at trommel screen part on every side on the described rotating cylinder inwall and be provided with secondary returning charge spiral; the described bottom that goes out gas tank is provided with feed box, and described feed box is communicated with trommel screen.
In above-mentioned internal return tablets press, be provided with a light cylinder between described flight and the classfied cone.
In above-mentioned internal return tablets press, be provided with the furnace gas sparger in the described gas inlet chamber, hot furnace gas enters from the side, enters in the rotating cylinder equably through the furnace gas sparger.
Compared with prior art, according to internal return tablets press of the present utility model, one section light cylinder is set in the rotating cylinder, relies on the segregation effect of itself and classfied cone to realize pre-classification.Main returning charge spiral is set in the rotating cylinder most of particulate is returned the rotating cylinder head, rest materials enters the stern roll sieve and carries out classification.Screen underflow (particulate, diameter is below 1mm) returns main returning charge spiral by secondary returning charge spiral, returns the rotating cylinder head again.The crusher that screen overflow (coarse grain, diameter is more than the 4mm) is delivered to out on the gas tank by the afterbody upgrading slot carries out fragmentation, and the material return roller after the fragmentation sieves.Intermediate material (diameter is the particle of 1-4mm) is qualified product, directly discharges rotating cylinder, enters next procedure.Realized full internal return, energy consumption is low, efficient is high, equipment is few.
Description of drawings
Fig. 1 is the schematic diagram of internal return tablets press of the present utility model.
Embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1; according to internal return tablets press of the present utility model; comprise rotating cylinder 1; be arranged on the gas inlet chamber 2 of rotating cylinder 1 head; by the spray gun 3 in the rotating cylinder 1 head insertion rotating cylinder; be arranged on the main returning charge spiral 4 on rotating cylinder 1 inwall; be arranged on the flight 5 on rotating cylinder 1 inwall; be arranged on the classfied cone 6 of rotating cylinder 1 afterbody; the trommel screen 7 that connects classfied cone 6; connect going out gas tank 8 and being arranged on out crusher 9 on the gas tank 8 of trommel screen 7; be positioned at trommel screen 7 part on every side on described rotating cylinder 1 inwall and be provided with secondary returning charge spiral 10; the described bottom that goes out gas tank 8 is provided with feed box 11, and described feed box 11 is communicated with trommel screen 7.
In above-mentioned internal return tablets press, be provided with a light cylinder 12 between described flight 5 and the classfied cone 6.
In above-mentioned internal return tablets press, be provided with furnace gas sparger (not shown) in the described gas inlet chamber, hot furnace gas enters from the side, in the furnace gas sparger enters rotating cylinder 1 equably.
Compared with prior art, according to internal return tablets press of the present utility model, one section light cylinder is set in the rotating cylinder, relies on the segregation effect of itself and classfied cone to realize pre-classification.Main returning charge spiral is set in the rotating cylinder most of particulate is returned the rotating cylinder head, rest materials enters the stern roll sieve and carries out classification.Screen underflow (particulate, diameter is below 1mm) returns main returning charge spiral by secondary returning charge spiral, returns the rotating cylinder head again.The crusher that screen overflow (coarse grain, diameter is more than the 4mm) is delivered to out on the gas tank by the afterbody upgrading slot carries out fragmentation, and the material return roller after the fragmentation sieves.Intermediate material (diameter is the particle of 1-4mm) is qualified product, directly discharges rotating cylinder, enters next procedure.Realized full internal return, energy consumption is low, efficient is high, equipment is few.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
