Description
Technical field
The utility model belongs to the controlled-release fertilizer production equipment technical field, relates to a kind of fluid bed that is suitable for continuously preparing membrane wrapping control-releasing fertilizer.
Background technology
Coating controlled-release fertilizer has become the new direction of fertilizer industry development; the main at present batch production method that adopts; the advantage of batch production is that output is big; the coating good uniformity; but its shortcoming is obvious equally, and energy consumption is higher, in addition; because need constantly to shut down and start, also affect adversely the service life of equipment component.
Have been found that and adopt a kind of " spouted bed " can produce high-quality coating controlled-release fertilizer grain, only there are the similar spouted bed simple report of production equipment continuously in the Japan and the U.S. at present, but find that these existing equipments have many defectives in use, for example continuous spouted equipment is established a plurality of dressing lattice, every single dressing lattice circulation primary, thereby dressing equipment is comparatively complicated, and flexibility is restricted.
The domestic equipment that does not up to the present also have real continuously preparing membrane wrapping control-releasing fertilizer, known have employing " the jet flow tower that a plurality of orders are provided with " intention to realize the purpose that continous way is produced, it mainly designs is that a slide valve to be opened/closed is set in each jet flow tower, and one extend upward and pass the conduit of slide valve in the closed condition of slide valve from contiguous jet flow tower bottom, is provided with an opening by the control of valve element between adjacent jet flow tower.This dressing equipment is by the fertilizer transfer condition in the manual observation jet flow tower, utilize the switching repeatedly of valve element on the adjacent jet flow tower wall and slide valve to realize that fertilizer flow to another jet flow tower from a jet flow tower, and need fixed cycle operator, therefore its complex steps, operation are comparatively complicated, prior this equipment that is to use still needs batch (-type) to feed intake, so it fails to realize the continous way production of coating controlled-release fertilizer.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of fluidized-bed for continuously producing membrane wrapping control-releasing fertilizer, is used for producing continuously coating controlled-release fertilizer, and solution batch production energy consumption is higher, the shortcoming of the easy loss of equipment.
The utility model fluidized-bed for continuously producing membrane wrapping control-releasing fertilizer is made up of the coating tower that a plurality of orders link to each other, and coating top of tower opening connects by airduct, and each coating tower is equipped with perforated distributor, guide shell and shower nozzle.Be provided with charging aperture on first coating tower, last coating tower is provided with discharging opening, and adjacent coating tower is communicated with by the sidewall opening on the tower, and charging aperture, sidewall opening and discharging opening are positioned on the same vertical section, and reduces one by one from high to low successively.
Above-mentioned each coating top of tower all is provided with the screen cloth of a mesh size 1.5-2.0mm.To prevent that fertiliser granulates is fluidized gas and brings airduct into.
Described perforated distributor is positioned at the coating tower bottom, and there is opening at the perforated distributor center, and shower nozzle passes this open centre and is fixed on the coating tower bottom, establishes guide shell directly over the shower nozzle.
Shower nozzle in the above perforated distributor is single fluid shower nozzle or two-fluid shower nozzle, and the opening at described guide shell caliber size and perforated distributor center matches.
The number of above coating tower is advisable with 2-6.Preferred 3.
In the utility model equipment, be provided with perforated distributor and shower nozzle at each coating tower bottom, perforated distributor is used to pass through fluidizing gas, it is shaped as taper (25-35 ° of horizontal sextant angle scope), percent opening is 3-8%, its center opening part is provided with the screen cloth of 1.0-2.0mm (mesh size), shower nozzle passes the center fixation of this screen cloth at the coating tower bottom, certain distance is provided with a guide shell directly over shower nozzle, the opening bore of the bore of guide shell and perforated distributor bottom matches, size is consistent, and guide shell length is advisable with 25-50cm;
In the utility model equipment, on first coating tower, be provided with and add feed bin and be communicated with charging aperture.
Discharging opening on charging aperture on first coating tower, adjacent coating tower wall upper side wall opening and last coating tower position relation in vertical direction is: charging aperture is higher than coating tower wall upper side wall opening, coating tower wall upper side wall opening is higher than discharging opening, and tower wall upper side wall aperture position also reduces successively.As shown in Figure 1.
The beneficial effects of the utility model are: use the utility model equipment to be equipped with other process equipments and produce coating controlled-release fertilizer, simple to operate, not only can really realize continous way production, and avoid the troublesome operation of valve element and slide valve switch, cut down the consumption of energy, enhance productivity.
Description of drawings
Fig. 1 is the structural representation of fluidized-bed for continuously producing membrane wrapping control-releasing fertilizer described in the embodiment.Wherein, 1,2,3 is the coating tower, and 4 is guide shell, and 5 is support, and 6 is perforated distributor, and 7 is opening, and 8 is shower nozzle, and 9 for adding feed bin, and 10 is charging aperture, and 11,12 is sidewall opening, and 13 is discharging opening, and 14 is screen cloth, and 15 is airduct.
The specific embodiment
Describe the technical scheme that the utility model proposes in detail below in conjunction with drawings and Examples, but be not limited thereto.
As shown in Figure 1, the membrane wrapping fluidized-bed equipment of this continous way is made up of coating tower 1, coating tower 2 and coating tower 3 that three orders link to each other, three long-pending 0.8m that are all of coating tower section
