Abstract
The utility model relates to the field of composite mixed fertilizer production equipment, and in particular relates to a pelleting device for producing a composite mixed fertilizer. The device is characterized in that a spiral heating pipe and a filter screen are arranged in a urea melting tank; a temperature control valve, a urea feeding hole, a stirrer, a temperature gauge, a urea liquid pump and a water flow meter are connected outside the urea melting tank; the urea melting tank is connected with a pelletizer by a pipeline; an upper pipeline is provided with a pipeline temperature control valve; a lower pipeline is provided with a urea liquid flow meter and a nozzle. After the technical scheme is adopted, the pelleting device can be used for controlling the flow rate, the temperature, the liquid level and the ratio of nutrient of material in a full-automatic way, thus completely avoiding the production of biuret, guaranteeing the stability of production and reliably guaranteeing the quality and the yield of the compound fertilizer.
Description
Technical field
The utility model relates to produces the compound mixing fertilizer apparatus field, is a kind of prilling granulator of producing compound mixing fertilizer.
Background technology
In recent years, the fertile granulation process commonly used of compound has extrusion process, granulating method, 3 kinds of technologies of slurry process.The extrusion process current production rate is less, and slurry process is restricted greatly because of its scale of investment, and granulating method is simple because of its technology, investment is less is relatively accepted by most of producers.Pellet granulation is subjected to the influence of property of raw material, particularly is restricted during high nitrogen composite fertilizer at the fertilizer of producing some special formulations.
The urea smelting and spraying granulation process belongs to half urine slurry method, and production principle has both advantages concurrently between granulating method and slurry process, can produce high nitrogen compound fertilizer, has overcome the difficult problem that slurry process can not be produced high phosphatic manure simultaneously again.Can significantly improve output, and product particle mellow and full smooth, intensity is high, prevented from caking, the adaptability to starting material, prescription in the production is strong.
But because the singularity of urea structure, high depth urea (〉=99.5%) obtains 130 ℃ in temperature, and when temperature surpassed 132 ℃, solid urea can accompany biuret to produce when fusion, the fertilizer that biuret exceeds standard is unfavorable to crop growth, can cause and burn the seedling underproduction.Therefore, the generation of the biuret in the control urea melting process is the key of utilizing the urea smelting and spraying granulation.
Summary of the invention
The utility model purpose is to overcome the difficulty that the common urea melt spray granulation easily produces biuret, and the defective of operation control difficulty, provides a kind of technology simple granulation production equipment.
The technical solution of the utility model is: a kind of prilling granulator of producing compound mixing fertilizer, it is characterized in that urinating in the molten groove helical heating pipe and filtering net are housed, the molten groove of urine is circumscribed with temperature control valve, urea opening for feed, stirrer, thermometer, urine pump and water ga(u)ge; The molten groove of urine links to each other with tablets press by pipeline, at last pipeline the pipe temperature control valve is housed, and at following pipeline urine under meter and nozzle is housed.
Owing to adopted technique scheme, mass flow, temperature, liquid level, nutrient proportioning are carried out full automatic control, avoided the generation of biuret fully, guarantee the stability of producing, make compound manure quality, output reliably guaranteed.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the drawings: 1, temperature control valve; 2, the molten groove of urine; 3, helical heating pipe; 4, urea opening for feed; 5, stirrer; 6, water ga(u)ge; 7, filtering net; 8, thermometer; 9, urine pump; 10, pipe temperature control valve; 11, urine under meter; 12, nozzle; 13, tablets press.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
In Fig. 1, in the molten groove 2 of urine helical heating pipe 3 and filtering net 7 are housed, the molten groove 2 of urine is circumscribed with temperature control valve 1, urea opening for feed 4, stirrer 5, thermometer 8, urine pump 9 and water ga(u)ge 6; The molten groove 2 of urine links to each other with tablets press 13 by pipeline, at last pipeline pipe temperature control valve 10 is housed, and at following pipeline urine under meter 11 and nozzle 12 is housed.
The whole process of urea smelting and spraying granulation process is controlled by computer, and the external heat steam is input to sub-cylinder, and its pressure is detected and control by tensimeter.The steam that is come out by sub-cylinder divides both direction, and a part is heating steam, is passed to the helical heating pipe of urinating in the molten groove 23 by temperature control valve 1, to urinating molten groove 2 indirect heating, the urea granules that fusion is entered by urea opening for feed 4.The operational throughput of urea solid particle is sent into by the electronic belt scale weighing of computer control; water by water ga(u)ge 6 input corresponding proportions melts groove 2 to urine; under the stirring of stirrer 5; urea begins fusion and obtains the urine of complete molten state by filter screen 7 when reaching certain temperature; by urine pump 9 urine of molten state is extracted out; by the amount of the urine under meter 11 control urines of computer control, be sprayed onto on the pressed powder in the tablets press 13 by nozzle 12 and carry out granulation.
The temperature that urine melts in the groove is detected by thermometer 8, regulates the operational throughput of heating steam by temperature control valve 1 and controls.
Purging steam when another part steam is urine piping insulation steam in the normal productive process and equipment cleaning, vapor volume is by 10 controls of pipe temperature control valve.
