Description
Technical field:
The utility model belongs to the slow release fertilizer technical field, particularly slow-release fertilizer self-control coating coating device.
Background technology:
Currently marketed agricultural fertilizer is many based on mineral manure, this class fertilizer since the fertilizer self property after applying scholar's earth, early stage release property is strong, easily volatilization loss, utilization ratio low, cause resource waste and pollution atmosphere and edatope.Therefore, produce and use the dissolving that can slow down fertilizer and the slow release fertilizer of release rate to become the use cost that improves utilization rate of fertilizer, reduces fertilizer and improved one of important channel of crop yield.Existing slow release fertilizer is divided into chemical combination type, coated, Envelope type and mixed type four big classes, wherein, film-coated and slow release fertilizer gains great popularity with its good releasing effect, but because existing coating process can't be realized the function that coated fertilizer has, so film-coated and slow release fertilizer does not also use widely in China.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and the slow-release fertilizer self-control coating device is provided, this device simple in structure, be easy to promote, and the slow release effect of coated fertilizer can be given full play to.
The technical solution of the utility model is: a kind of slow-release fertilizer self-control coating device is characterized in that: be made up of coating agent conservation tank and coating tube, warming apparatus is installed in the coating agent conservation tank, this device is connected with temperature, time-controlling arrangement; In the coating tube coating device is set, the two ends of this coating device are coating district and baking zone, form level and smooth district between them; Some flights are installed in coating district and the baking zone, and angle in becoming between the barrel of these flights and coating tube is equipped with coating agent nozzle and high-pressure air nozzle in the coating district; Coating agent conservation tank and coating agent nozzle pass through pipe connection; The middle part of coating tube is provided with thermal chimney.
Angle is between 45 degree-75 degree in becoming between the barrel of above-mentioned flight and coating tube.
The air outlet of above-mentioned thermal chimney extends to the engagement edge of level and smooth district and baking zone.
In the above-mentioned coating tube secondary coating device can be set continuously, wherein the air outlet of thermal chimney extends to the level and smooth district of secondary of secondary coating device and the engagement edge in secondary drying district.
The utility model has the advantages that: simple in structure, be easy to promote, this device is by throwing coated fertilizer in the coating district, between smoothly distinguishing, keep evenly fertiliser granulates, at baking zone particle is dried, by these programs coated fertilizer is wrapped on the fertilizer, the slow release effect of coated fertilizer can be given full play to.Also can the extend length of coating tube of this device realizes the secondary coating, and the control that can pass through temperature, time-controlling arrangement sprays the different coating agent of slow-release time.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model carries out the secondary coating.
Embodiment:
Embodiment 1:
As shown in Figure 1: a kind of slow-release fertilizer self-control coating device is made up of one group of coating agent conservation tank 1 and coating tube 2, and one group of coating agent deposit is irritated and is made up of three coating agent conservation tanks, and each deposit is equipped with three kinds of coating agent that slow-release time is different respectively in irritating.Warming apparatus 3 is installed in the coating agent conservation tank, and this device is connected with temperature, time-controlling arrangement 4; In the coating tube coating device is set, the two ends of this coating device are coating district 5 and baking zone 6, form level and smooth district 7 between them; Some flights 8 are installed in coating district and the baking zone, become the interior angles of 45 degree-75 degree between the barrel of these flights and coating tube, coating agent nozzle 9 and high-pressure air nozzle 10 are housed in the coating district; Coating agent conservation tank and coating agent nozzle pass through pipe connection; The middle part of coating tube is provided with thermal chimney 11.The air outlet of thermal chimney extends to the engagement edge of level and smooth district and baking zone.The working process of this device is: composite fertilizer is packed in the coating tube, at first with the flight in the coating district it is thrown aloft.Be controlled at coating agent between 50-60 ℃ with temperature and be passed in the coating agent nozzle in the coating district and spray this moment, the high-pressure air of high-pressure air nozzle ejection simultaneously, and in coating agent nozzle place formation negative pressure, attract the coating agent to mix ejection with high-pressure air, form vaporific gas, thereby form the coating process, the coating agent is sprayed on the fertilizer surface.The composite fertilizer that has sprayed enters level and smooth district, and compound fertilizer granules is kept evenly, enters baking zone then and kicks up with the temperature that feeds after 85-100 ℃ hot blast is dried, and enters refrigerating unit 17 at last, and cooling gets final product.The coating agent that above-mentioned three kinds of slow-release time are different can be carried out the control of spray time by temperature, time-controlling arrangement.Said temperature, time-controlling arrangement are connected to form by the magnetic valve and the time relay.
Embodiment 2:
As shown in Figure 2: in the coating tube secondary coating device can be set continuously, by secondary coating district 12, secondary smoothly distinguish 13 and secondary drying district 14 form, wherein the air outlet of thermal chimney extends to the level and smooth district of secondary of secondary coating device and the engagement edge in secondary drying district.Coating agent nozzle 9,15 in twice coating device is connected with one group of coating agent conservation tank 1,16 respectively.The working process of this device is: urea is packed in the coating tube, with flight in the coating district for the first time it is being thrown aloft.Be controlled at coating agent between 50-60 ℃ with temperature and be passed in the coating agent nozzle in the coating district and spray this moment, formed negative pressure when the high-pressure air nozzle sprayed coating agent nozzle simultaneously herein, attract the coating agent to mix ejection with high-pressure air, form vaporific gas, thereby form the coating process, make coating agent spray on the fertilizer surface.The urea that has sprayed enters level and smooth district, and urea granules is kept evenly, enters baking zone then and kicks up and dry at 85-100 ℃ hot blast with the temperature of feeding.Carry out the coating second time then, the coating process enters refrigerating unit 17 at last with the coating process is identical for the first time, and cooling gets final product.
