Embodiment 1

[0020] Spraying device for coating solution in the production of controlled release fertilizer, the structure is as follows figure 1 As shown, it includes a regulating valve 1, a flow meter 2, a filter 3, a spray gun 4, a heat preservation valve 5, a jacket pipe 6, a heating pipe 7, a heating inlet valve 8, a metal hose 9 and a heating outlet valve 10, wherein the The regulating valve 1, the flow meter 2, the filter 3, the heat preservation valve 5, and the spray gun 4 are connected in sequence; The interlayer of the filter 3 is connected with the insulation jacket 12, and the insulation jacket 12 is connected with the interlayer of the jacket pipe 6, and finally connected to the heating outlet valve 10 through the insulation valve 5.

[0021] The spray gun 4 can be a single-fluid spray gun, on which a nozzle 11 is arranged, and the height of the nozzle 11 from the material layer is 500 mm.

[0022] The nozzle 11 can be a single-head nozzle or a multi-head nozzle, and the dia...

Embodiment 2

[0025] The structure of the spraying device for coating solution in the production of controlled release fertilizer is the same as that in Example 1, the difference is that the regulating valve 1 and the flow meter 2 also have a heat preservation jacket 12 communicating with the interlayer of the jacket pipe 6 .

Embodiment 3

[0027] The structure of the coating solution spraying device in the production of controlled-release fertilizers is the same as in Example 1, except that the height of the nozzle 11 from the material layer is 250 mm.

Abstract

The invention discloses a spraying device for envelope solution during the production of control sustained-release fertilizer, which comprises a regulating valve, a flowmeter, a filter, a heat preservation valve, a spray gun, a jacket pipe, a heating pipeline, a heating inlet valve, a metal hose and a heating outlet valve, wherein the regulating valve, the flowmeter, the filter, the heat preservation valve and the spray gun are connected in sequence; a heating jacket is communicated with the jacket pipe through the heating inlet valve; the metal hose is communicated with an interlayer of the jacket pipe; the filter is provided with a heat preservation jacket; and the heat preservation jacket is communicated with the interlayer of the jacket pipe, and finally connected with the heating outlet valve through the heat preservation valve. The technical advantages are that the pipeline is no longer plugged through the condensation of the envelope solution because the heat of the envelope solution is preserved by heating medium in the delivery process; impurities in the envelope solution are filtered by adding the filter, thereby solving the problem of nozzle plugging; the spray gun adopts a single fluid spray gun, without the need of compressing gas, thereby ensuring the completely closed cycle of the spray gun without adding the amount of fluidizing gas and discharging to the outside, and reducing the load of solvent recycle.

Description

technical field [0001] The invention belongs to the field of controlled-release fertilizer production equipment, in particular to a coating solution spraying device in the production of coated controlled-release fertilizers. Background technique [0002] Coated controlled-release fertilizer is a new type of fertilizer that wraps a special film on the outer layer of traditional fertilizers to control the release rate and amount of nutrients according to the nutrient requirements of crops, so that the nutrient release curve is consistent with crop requirements. The outstanding feature of this fertilizer is that effective nutrients are supplied synchronously according to the growth curve of crops, so that the effective utilization rate of fertilizer nutrients is greatly improved. Under the premise of ensuring crop growth, compared with fertilizers with the same concentration, the utilization rate of fertilizer efficiency can be increased by 50%. The above can greatly reduce the...
