The purpose of this utility model is to provide a kind of spray urine length of producing urea-base compound fertilizer apart from the transfer line device, industrial synthetic urine is delivered directly to the production scene of composite fertilizer.
For realizing above-mentioned utility model purpose, the technical solution of the utility model is to provide a kind of spray urine length of urea-base compound fertilizer of producing apart from the transfer line device, this pipe installation is made of urine insulation transfer line and urine concentration control device, the urine concentration control device is by motor-driven control valve, flow sensor, setter, the diluent injection pump constitutes, go here and there first section that is contained in urine insulation transfer line device before and after motor-driven control valve and the flow sensor, the injection mouth of pipe of diluent injection pump is connected on the urine pipeline of the urine insulation transfer line after the flow sensor, and setter is by the switch degree of access flow signal of sensor control motor-driven control valve and the motor speed of diluent injection pump.
Urine insulation transfer line is reverse jacketed type insulation pipeline, the urine pipeline periphery of the main center of this pipeline is enclosed with the steam insulation chuck, between parallel steam-pipe and the water of condensation conduit of being provided with in the next door of main body, steam-pipe and water of condensation conduit and steam insulation chuck respectively by being connected with condensed water discharge pipe along the equally distributed steam access tube of the direction of lay.
Described steam insulation chuck is confessed one's crime to tail is separated into segmental structure, and the stem of each section is communicated with described steam access tube, and the afterbody of each section is communicated with condensed water discharge pipe.
Described setter is controlled the motor speed of diluent injection pump by frequency transformer.
Described diluent injection pump is a ram pump.
Be communicated with mediation steam access tube by stopping valve on the urine pipeline before the described motor-driven control valve.
The outlet of described water of condensation conduit feeds a hot water tank, and the inlet of the tail pipe of ram pump also feeds this hot water tank.
From technique scheme as can be seen, the utility model is carried under specific temperature and concentration, can guarantee that the smoothness of urine is carried, and can guarantee that the content of biuret in course of conveying can not increase substantially simultaneously.
In the urine concentration control device of transfer line device of the present utility model, be 99.7% urine flow, guaranteed the stable of composite fertilizer's prescription with the direct controlling concn of electromagnetic flow transducer.The magnetic flow meter induced signal is by the switch degree of setter control motor-driven control valve, isochronous governor is by the rotating speed of frequency transformer electrodeless variable-speed control piston pump motor, guarantee with being consistent to the former amount of urine of urine pipeline inflow and the diluting water of the corresponding proportion that configures in a flash, carry urine concentration stable thereby make, guaranteed the manufacturing technique requirent of conveying and composite fertilizer.
The diluent technology because ram pump top hole pressure and system pressure maintenance balance, employing ram pump are annotated in 99.7% urine can prevent that urine from refluxing, and guarantees the continuity of water filling, thereby has guaranteed the continuous conveying of 92-99.7% urine.
In the course of conveying of urine, can lose the part heat, temperature reduces, in order to prevent the urine crystallization, blocking pipe, the utility model transfer line device adopt reverse chuck insulation measure, in insulation jacket, feed steam segmentation correspondence again from tail to head section and discharge water of condensation, guarantee the constant temperature conveying, made each segment temperature substantially constant, avoided urine cooling blocking pipe.
Also adopt steam condensate (water) as dilution liquid in the utility model, directly add in the urine pipeline urine is diluted, because it is approaching to steam the temperature and the 99.7% urine temperature of phlegma, can not cause urine cooling blocking pipe because of water filling, the two is mixed in proportion, can reconcile urine concentration, produce needs to adapt to composite fertilizer.
Utilize urine directly to introduce complex production system, can save the granulation of granular urea, saved granulation, packing, transportation and crushing cost usefulness, expense of saving nearly hundred yuan per ton has reduced the production cost of composite fertilizer significantly.
The utility model also has obvious energy-saving effect, utilize the heat heating granulation material in the urine, can save a large amount of steam and oven dry heat energy, it is compound to utilize urine directly to spray, also saved in a large number, but also solved the problem that the Biuret Content that causes therefrom increases effectively urea granules second-heating fused heat.
Utilize the cohesiveness of urine itself, can produce formula for a product and be difficult for the granulated composite fertilizer of reuniting, and stopping composition can improve, solved the product that tower granulation can not be produced, the returning charge rate is reduced to 35% by original 65%, and the urea-base compound fertilizer nutrient of producing with this mode be evenly distributed smooth surface, uniform particles, granule strength is big, and the market competitiveness improves greatly.
This technology centering, little urea plant are adjusted the product mix, and reduce investment, and the good technical guarantee is provided.
