Abstract
The utility model discloses a continuous controlled-release fertilizer boiling fluidized bed device which is characterized by comprising an air chamber, a boiling chamber, a feed port and a discharge port, wherein an air inlet is formed at the lower end of the device; the air chamber is arranged at the bottom of the device; a card is arranged at the upper end of the air chamber; an air distribution plate is mounted in the air chamber; an air cap is arranged on the card; the boiling chamber is arranged on the upper side of the card; the feed port is formed at the upper end of the boiling chamber; a spray head is mounted in the boiling chamber; the upper end of the boiling chamber is an expansion section; the discharge port is formed in the lower part of the expansion section; the top of the expansion section is a top cover; and the upper part of the top cover is an air outlet. The device disclosed by the utility model can realize continuous large-scale production, reduces the collision probability between the fertilizer and the cylinder wall during coating, and improves the coating quality.
Description
Technical field
The utility model relates to the fertiliser production equipment technical field, specifically the fluidizing fluid-bed device of a kind of continuity slow-release or control-release fertilizer.
Background technology
Slowly-releasing and outer slowly-releasing were two kinds in slow-release or control-release fertilizer comprised, interior slowly-releasing is that the interpolation inhibiter is that fertilizer efficiency slowly discharges in fertiliser granulates, the outer slow-release fertilizer that China gives priority to is to coat a skim on the surface of waste material particle, fertilizer efficiency is slowly discharged, improve fertilizer utilization ratio, existing slow-release fertilizer production unit mostly is the fluidizing fluid-bed and rotary drum coating of intermittent type, in recent years domestic-developed rotary drum fluid-bed.The fluidizing fluid-bed coating effect of intermittent type is better, but owing to be batch production, single device throughput is less, and level of automation is relatively poor, can't realize mass-producing.Though the rotary drum coating can be realized continuous production, the coating quality is more fluidizing fluid-bed poor, and the fertile controlled release time of the controlled release of production is shorter.Though the rotary drum fluid-bed rotary drum coating of comparing has improved the coating quality; serialization, large-scale production have been realized simultaneously; but it is rotary drum fluid-bed less in fluidised space; the fertiliser granulates of coating under the situation of complete drying not and the probability of collision of barrel bigger; also cause the adhesion between the coated granule, still can't guarantee the coating quality fully.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and the fluidizing fluid-bed device of continuity slow-release or control-release fertilizer that a kind of coating serialization of seething with excitement is provided, improves the coating quality, can accomplish scale production.
For achieving the above object, the technical solution adopted in the utility model is: comprise air compartment, boiling-house, opening for feed, discharge port, the lower end of described device is provided with blast inlet, the bottom of described device is provided with air compartment, the upper end of described air compartment is provided with card, air distribution plate has been installed in the air compartment, be laid with blast cap on the card, the card upside is boiling-house, and the boiling-house upper end is provided with opening for feed, and shower nozzle is installed in the boiling-house, the boiling-house upper end is expanding reach, the bottom of expanding reach is equipped with discharge port, and the top of expanding reach is top cover, and top cover top is air outlet.
Further, it is cylindric that described air compartment is that top is, and the bottom is the inverted cone shape.
Further, described air distribution plate is installed in described turbination inside.
After adopting said structure; the utility model beneficial effect is: the utility model has solved the problem that mass-producing can't be produced, be realized to the coating that seethes with excitement continuously; can accomplish continuous production; avoided the rotary drum coating to produce the fertile short defective of controlled release time of controlled release simultaneously; compare with rotary drum fluid-bed coating; the utility model has reduced fertilizer during coating and the probability of collision of barrel, has improved the coating quality.The utility model integrates granulated fertilizer spraying, coating curing, can realize extensive, the serialization production of slow-release or control-release fertilizer, being sprayed in the process that particle seethes with excitement up and down of fertilizer finished, finished the curing of coating simultaneously, can not produce adhesion each other, the breakdown of coating that causes because of particle and equipment friction can not take place yet, can improve the sustained release performance of slow-release or control-release fertilizer greatly, charging and discharging are carried out simultaneously, accomplished serialization production, the ability of the equipment of giving full play to has reduced facility investment.

Fig. 1 is the utility model structural representation.
Among the figure: 1, blast inlet; 2, air distribution plate; 3, air compartment; 4, card; 5, blast cap; 6, boiling-house; 7, shower nozzle; 8, opening for feed; 9, expanding reach; 10, top cover; 11, air outlet, 12, discharge port.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the fluidizing fluid-bed device of a kind of continuity slow-release or control-release fertilizer described in the utility model, comprise air compartment 3, boiling-house 6, opening for feed 8, discharge port 12, the lower end of described device is provided with blast inlet 1, and the bottom of described device is provided with air compartment 3, and it is cylindric that described air compartment is that top is, the bottom is the inverted cone shape, in the inverted cone shape part air distribution plate 2 is installed, is evenly distributed for the wind that will enter air compartment 3, guarantee that fluidizing fluid-bed boiling is uniform and stable; The upper end of described air compartment 3 is provided with card 4, is laid with blast cap 5 on the card, and card 4 is used for supporting material and the blast cap 5 in the boiling-house; The purpose one of blast cap 4 is to improve the wind speed that enters boiling-house 6 to meet the requirements of numerical value, and assurance is that fertiliser granulates all seethes with excitement, and blast cap side direction perforate has simultaneously avoided fertiliser granulates to enter air compartment by aperture; Card 4 upsides are boiling-house 6, and boiling-house 6 upper ends are provided with opening for feed 8, and shower nozzle 7 is installed in the boiling-house, and shower nozzle 7 mainly is that the coated fertilizer that needs add is fully atomized, and is sprayed onto the surface of chemical fertilizer granule, forms uniform coating layer; The boiling-house upper end is expanding reach 9, the bottom of expanding reach is equipped with discharge port 12, the top of expanding reach is top cover 10, top cover top is air outlet 11, the purpose of expanding reach 9 is in order to reduce wind speed, most fertiliser granulates is come back to carry out the repetition coating in the boiling-house, guarantee that the fertiliser granulates coating is complete; The bottom of expanding reach 9 is provided with discharge port 12; discharge port is arranged on the bottom of expanding reach; purpose is to discharge fluidizing fluid-bed device smoothly for the good fertiliser granulates of coating; because; after air-flow reaches expanding reach 9; gas speed reduces significantly, can not guarantee that fertiliser granulates reaches boiling state, and fertiliser granulates can enter discharge port and discharge fluidizing fluid-bed device.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model
In the patent claim.
