Description
Technical field
The utility model relates to a kind of industrial production chemical fertilizer prilling spry, particularly is applicable to the used prilling spry of high-concentration compound fertilizer production.
Background technology
With prilling tower granulation production high density binary or Nitrogen, Phosphorus and Potassium is an emerging technology, its technological process is: a certain amount of solid powder (particle diameter 0.3-0.5mm) is joined the mixture that forms eutectoid point in the fused urea soln, leak into the prilling spry granulation then; The critical process of this technology is granulation, and is therefore quite strict to the requirement of granulating equipment: as can realizing continuous production, the final product quality of institute's output, shaping particles are good or the like; Existing shower nozzle, its structure is: the shower nozzle upper flanges is fixedlyed connected with the cone shower nozzle, and several straight shape spray orifices are distributed on the conical surface of cone shower nozzle; Adopt the prilling spry of this structure to produce high-concentration compound fertilizer, can't realize continuous production, and the final product quality of being produced is poor, its former because: 1, the slip because of production high density binary or Nitrogen, Phosphorus and Potassium is the suspension that contains solid particulate, its viscosity is big, solid particulate has a trend of constantly piling up when flowing through spray orifice, its trend diameter constantly enlarges, and finally causes the spray orifice obstruction and can't continue production; 2, because the proportion of solid materials is bigger, enter the deposition that can produce behind the shower nozzle from bottom to top, causing can't granulation; 3, in the process of production composite fertilizer, because of solid materials and liquid material hybrid reaction can produce bubble, adopt this shower nozzle, liquid, gas easily cause shaping particles bad with from the spray orifice ejection, and hollow more, final product quality is poor.
Summary of the invention
The purpose of this utility model is the defective that overcomes above-mentioned prior art, and a kind of granulation that links is provided, and the quality of finished product good of being produced, and is applicable to the novel prilling spry of high-concentration compound fertilizer production technique.
The utility model is realized by following proposal:
A kind of novel prilling spry, comprise that tapering is cone shower nozzle and the fixedly connected with it shower nozzle loam cake of 2 α, feed-pipe is located at the axis place of cone shower nozzle, the cone shower nozzle is provided with several conical spray orifices, evenly be fixed with 2-5 piece screw press plate on the described feed-pipe, the helix angle of screw press plate is α, and to shower nozzle sense of rotation tilt alpha angle, correspondence is provided with scraper on the screw press plate, scraper links to each other with the screw press plate by active pin shaft, and its bottom surface is vertical with cone shower nozzle bottom surface, and length is less than the cone sprinkler height, spring is located between scraper and the screw press plate, and eduction pipe is inserted on the shower nozzle and covers;
Described screw press plate is three, and correspondence is provided with three scrapers;
The length of described scraper is 1/3rd of cone shower nozzle, and is installed in successively on three blocks of screw press plates by the height order;
Described spray orifice is an inclined hole, and its vergence direction is opposite with the sense of rotation of cone shower nozzle, and the angle of inclination is α;
The end of described eduction pipe is near feed-pipe.
Advantage of the present utility model is: 1. the utility model adds three blocks of screw press plates in shower nozzle inside, and leave certain interval with the shower nozzle inwall, both can prevent slip cutout in the spray orifice, do not destroy the generation of normal liquid film again, simultaneously, the helix angle of screw press plate is identical with shower nozzle semi-cone angle α, and to shower nozzle sense of rotation tilt alpha angle, make slip the time, be subjected to a pressure consistent and the continuous granulation of " promotion " slip with the spray nozzle direction through screw press plate surface; 2. the utility model is installed three perpendicular to the shower nozzle inwall and utilize spring pressure and scraper that the shower nozzle inwall is close at screw press backboard face, and scraper length is taken as 1/3 of sprinkler height, both prevented to destroy the formation of liquid film, can eliminate the influence to granulation of shower nozzle inwall again owing to the bonding of eutectic multipolymer; 3. spray orifice is designed to inclined hole, the inclined hole direction is opposite with the shower nozzle sense of rotation, and the angle of inclination equals shower nozzle semi-cone angle α, and end toper before the inclined hole is amplified, and these settings can make material flow into spray orifice more swimmingly, reduce resistance to flow, reduction trend diameter, thus the product particle diameter increased effectively; 4. cover the setting of eduction pipe on the shower nozzle, can guarantee that the gas that produces in the granulation process can not spray from spray orifice, with the close feed-pipe in eduction pipe end, prevent that slip from flowing out from eduction pipe simultaneously.
The utility model can make the prilling tower granulation process of high-concentration compound fertilizer realize industrialization, serialization production fully, and final product quality obviously improves, and yield rate reaches more than 98%.
Prilling spry of the present utility model, also applicable to urea production, have the following advantages with the urea of this prilling spry production: 1. particle diameter is big, the average big 1-2mm of particle that produces than existing shower nozzle; 2. dust is few; 3. granule strength is big, is difficult for broken.
