Description

Continous way slow release fertilizer coating device

Technical field

The utility model relates to a kind of encapsulation tool of slow release fertilizer.

Background technology

Continuous development along with China's agricultural, the conventional composite fertilizer that is widely used, though can bring the good quality and high output of farm crop, but the pollution problem of environment is also troubling, the volatilization of effective constituent, loss in the common fertilizer, not only reduce fertilizer utilization ratio, caused the waste of resource, also human ecological environments such as underground water resources, soil have been caused pollution simultaneously.In order to solve the problem that common fertilizer brings, people bring into use a kind of new-type fertilizer---slow release fertilizer.

A kind of slow release fertilizer wherein as coating, is coated in sulphur liquid on the surface of urea solid with sulphur.Application number is 200510094057.3, denomination of invention is the patent application of " coating method of sulfur-containing mixture film ", introduce in an embodiment and use nozzle that fusion sulphur is sprayed toward the Granular Urea surface, but do not relate to the coating device of concrete production slow release fertilizer.

Summary of the invention

The utility model provides that a kind of production cost is low, the slow release fertilizer coating device of high efficiency, and the concrete technical scheme that it adopted is:

This coating device comprises the cylinder 1 that can rotate and is positioned at the charging box 2 of cylinder 1 front end and the feed box 3 of rear end, charging box 2 tops are provided with loading hopper 4, feed box 3 tops and bottom are respectively equipped with venting port 5 and discharge bucket 6, on the inwall of cylinder 1, be fixed with the charging guide plate 7 that is positioned at cylinder 1 forward position, be positioned at the blocking material ring 9 of cylinder 1 rear positions and be positioned at cylinder 1 medium position and the equally distributed flitch 8 of carrying, the bending that makes progress of the end of carrying flitch 8, the two ends that are positioned at the long stent 10 of cylinder 1 central shaft position are separately fixed on charging box 2 and the feed box 3, be fixed with flow deflector 11 and the retaining plate 12 that is positioned at flow deflector 11 belows on the long stent 10, flow deflector 11 inclined-plane angles are the close flitch 8 of carrying in acute angle and its end, be fixed with the shower nozzle 13 that evenly is arranged in parallel and is interconnected on the retaining plate 12, the direction of shower nozzle 13 and cylinder 1 axis normal and towards flow deflector 11 inclined-planes.Cylinder (1) connects with transmission mechanism (14), and shower nozzle (13) is communicated with liquid-transport pipe-line by shotcrete pipe.

Therefore this device can use a plurality of shower nozzles that urea granules is sprayed repeatedly simultaneously, uses this device can be to a large amount of raw material coatings in the short period of time, and coating is evenly abundant, has the production efficiency height, the measured characteristics of coating matter.This device is easy to assembly, simple to operate, and the product of being produced meets the required standard of country.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is external form figure of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As Fig. 1, shown in 2 and 3, the cylinder 1 of this device main body for rotating, be respectively equipped with charging box 2 and feed box 3 in cylinder 1 rear and front end, charging box is provided with loading hopper 4, feed box 3 is provided with discharge port 6 and venting port 5, on the inwall of cylinder 1, be fixed with the charging guide plate 7 that is positioned at cylinder 1 forward position, be positioned at the blocking material ring 9 of cylinder 1 rear positions and be positioned at cylinder 1 medium position and the equally distributed flitch 8 of carrying, the bending that makes progress of the end of carrying flitch 8, the two ends that are positioned at the long stent 10 of cylinder 1 central shaft position are separately fixed on charging box 2 and the feed box 3, be fixed with flow deflector 11 and the retaining plate 12 that is positioned at flow deflector 11 belows on the long stent 10, flow deflector 11 inclined-plane angles are the close flitch 8 of carrying in acute angle and its end, be fixed with the shower nozzle 13 that evenly is arranged in parallel on the retaining plate 12, the direction of shower nozzle 13 and cylinder 1 axis normal and towards flow deflector 11 inclined-planes, the shower nozzle 13 that is interconnected connects liquid-transport pipe-line by shotcrete pipe.

Cylindrical shell 1 rotates under the drive of transmission mechanism 14, rotates simultaneously thereby make charging guide plate 7 and carry flitch 8.Add the urea granules after heating in the rotary barrels 1 by loading hopper 4 by utility appliance this moment, by the charging guide plate 7 that is rotating the material district is carried in the material importing, material is carried to certain position shed downwards by carrying flitch 8, carry the position that flitch 8 sheds the whereabouts according to the material needs and have certain knuckle angle.When shedding, falls granular urea on the flow deflector 11, urea granules is along the 11 downward landings of plate current plate, Molten sulphur enters shotcrete pipe by liquid-transport pipe-line, then by shower nozzle 13 with atomizing state ejection and attached to the urea granules surface of landing, particle falls the back and is mentioned by the flitch 8 of carrying of back under the effect of gravity, the material that is raised travels forward along cylindrical shell 1 direction, and then fall on the flow deflector 11, after flow deflector 11 landings, adhered to by the feed liquid of next shower nozzle 13 ejection, apply so repeatedly, final granular urea surface is adhered to uniformly by sulphur liquid, finish urea overlay film process, be located at the blocking material ring 9 of carrying rear portion, material district and can increase the material stop, the overlay film time makes overlay film more even, and last material is drawn off by the discharge port 6 of feed box 3.

Flow deflector 11 and retaining plate 12 do not rotate with the rotation of cylindrical shell 1 on fixed length support 10, are coated with the waste gas that produces in the membrane process and are discharged by venting port 5, enter exhaust treatment system and carry out vent gas treatment.
