Description
Technical Field
The invention relates to the technical field of chemical product production equipment, in particular to a novel granulator.
Background
An ammoniation rotary drum granulator is a key device for producing ammonium phosphate products (DAP and GMAP) and various NPK compound fertilizers, an ammonia distributor and a bracket (a colter for short) for fixing the ammonia distributor in the ammoniation rotary drum granulator are core components of the granulator, the installation positions and angles of the ammonia distributor and the colter are key factors influencing the production load of the granulator, the granulation quality and the particle size distribution, the ammonia distributor and the colter of the traditional ammoniation granulator are designed and installed in the axial direction or the radial direction of the granulator, the installation angle is designed according to the rotating speed of a cylinder body, the installation angle is traditionally installed on one side (namely one side in the positive rotation direction) in the material turning direction, and the installation angle is 5-50 degrees (the angle is the included angle between a central pipe beam of the granulator and the ammonia distributor or the colter along the vertical line). The granulator with the ammonia distributor and the coulter arranged in the angle range has the following problems:
1. the slurry sprayed by the slurry spray head is easy to adhere to the ammonia distributor and the coulter, and is adhered into large blocks along with the increase of the adhesive materials on the ammonia distributor and the coulter, so that the rubber plate on the inner wall of the granulator is rubbed, the load of the granulator is increased, and the transmission equipment of the granulator is damaged in severe cases; meanwhile, the abrasion of the rubber plate of the granulator is aggravated, the service life of the granulator is shortened, and the service life of the rubber plate can only reach about 20 days under severe conditions. Secondly, the large materials adhered to the ammonia distributor and the coulter block the materials in the granulator from stably moving forward, the operation speed of the granulated materials in each spraying granulation area is fast and slow, the retention time is short, the times and the quantity of the granulated materials sprayed and coated in the granulation area are different, and the materials discharged from the granulator are uneven in dryness and wetness, differentiated in two poles of granularity, large, small, rough and unsmooth in particle and poor in roundness.
2. The bold material that bonds on ammonia distributor and coulter to and the bold material that bonds at central tubular beams top, along with the rotation of granulator, rub, the extrusion, part bold material can drop to the granulation material bed, drop at the ammonia distributor, the bold material between the coulter, receive the ammonia distributor, the blockking of coulter, unable normal roll shifts out the granulator, along with the granulator rotates, bold material is spouted the coating many times repeatedly in the granulation district, bold material constantly grows up, be spouted the moisture by the ground paste in the area of adding, the material that the cohesiveness is stronger is rolled by bold material and is bonded, form bigger bold material very fast, big reaching about 2000kg, more can't roll out granulation area influence production normal clear, along with the granulator rotates, bold material has three aspect very unfavorable influence:
(1) the granulation rubber plate is damaged by smashing, and when the granulation rubber plate is seriously damaged, a new rubber plate is smashed one day;
(2) the ammonia distributor and the coulter are deformed due to extrusion and damage, the ammoniation granulation effect is influenced, and the ammonia distributor and the coulter are directly extruded and broken in serious cases, so that the ammonia loss is increased, and the production is forced to stop.
(3) The large material crushes and crushes the granules which are sprayed, coated and granulated, so that the granulated granular materials have uneven and irregular sizes and poor roundness;
slurry pipes and nozzles in the granulator are easily extruded and damaged by large materials, and the granulation condition is increasingly poor;
3. the ammonia distributor and the coulter are easy to wear and corrode, the ammonia distributor and the coulter need to be replaced at least one year, the ammonia distributor and the coulter are arranged in a region where slurry is sprayed, the slurry is sprayed out and then is easy to spray on the ammonia distributor and the coulter, the slurry with low pH value corrodes the ammonia distributor and the coulter, and in addition, the ammonia distributor and the coulter are completely buried in a granulating material bed, so that the material bed is worn greatly due to repeated operation of the material bed.
4. The device is low in operation rate and frequent in operation and shutdown, once the large materials of the granulator are bonded to a certain extent, the load of the granulator is rapidly increased, the current is increased, the fluctuation is large, the granulation and granulation are poor, the granulator needs to be stopped to clean the large materials in the granulator for 1-2 times almost every shift, the cleaning time is 1-2 hours every time, and the labor intensity and the safety risk of cleaning are increased.
