Problems solved by technology

Therefore, if controlled-release fertilizers are applied to rice or ponds, the fertilizers floating on the water will gather together with the wind, which is not conducive to uniform fertilization, and may float away with the water flow, resulting in waste of resources

Embodiment 1

[0019] Depend on figure 1 It can be seen that the special device for realizing the anti-floating treatment method of controlled-release fertilizer in the present invention includes: quantitative feeder 1, solution preparation device 2, flowmeter 3, rotating drum 4 and finished product silo 5, and described quantitative feeder 1 Connected to the feed port of the drum 4, the solution preparation device 2 is connected to the drum 4 through the flow meter 3, and the discharge port of the drum 4 is connected to the finished product bin 5.

[0020] The solution preparation device 2 can be a pressure tank plus an air compressor, or a storage tank plus a liquid pump; the quantitative feeder 1 includes a belt scale and a conveyor belt.

Embodiment 2

[0022] Utilize the device described in embodiment 1 to carry out the anti-floating treatment of the controlled-release fertilizer. The anti-floating agent uses water-soluble azone, and absolute ethanol is used as diluent. The solution configuration device 2 adopts a pressure tank and an air compressor, and the dosage per ton of product is respectively 0.5kg, 1kg, 2kg, and 3kg. The specific operation steps are as follows:

[0023] Step 1: Add 50kg of water-soluble azone and 5kg of absolute ethanol into the pressure tank and mix well, close the filling valve, turn on the air compressor, and adjust the pressure of the pressure tank to 1-2MPa.

[0024] Step 2: Start the quantitative feeder 1, the coated slow-release fertilizer is transported into the drum 4 through the conveyor belt, preheat the controlled-release fertilizer to 55-75°C, open the liquid spray valve, adjust the flow rate of the flow meter 3, and put the water-soluble Azone is sprayed onto the fertilizer granules, a...

Embodiment 3

[0027] Utilize the device described in embodiment 1 to carry out the anti-floating treatment of the controlled-release fertilizer. The anti-floating agent uses sodium dodecylsulfonate solution. The solution configuration device 2 adopts a storage tank and a liquid pump, and the dosage per ton of product is respectively 0.5kg, 1kg, 2kg, and 3kg. The specific operation steps are as follows:

[0028] Step 1: Add 50kg of sodium dodecylsulfonate solution into the storage tank.

[0029] Step 2: Start the quantitative feeder 1, the coated slow-release fertilizer is transported into the drum 4 through the conveyor belt, preheat the controlled-release fertilizer to 55-75°C, turn on the liquid pump and spray valve, adjust the flow rate of the flow meter 3, The sodium dodecylsulfonate solution is sprayed onto the fertilizer granules, and as the drum 4 rotates, the fertilizer granules move continuously to complete the anti-floating treatment.

[0030] The third step: after the anti-floa...

Abstract

The invention discloses a method for anti-floating treatment of coated controlled-release fertilizer and a device thereof. The method comprises the following steps: anti-floating agent is coated on the surfaces of coated controlled-release fertilizer granules, so as to realize the effect that the coated controlled-release fertilizer does not float in water. The method can perfectly solve the problem of floating of the controlled-release fertilizer in water and the problems of uneven fertilization and nutrient loss which are caused by the floating of the fertilizer; in addition, the original process of the method for the controlled-release fertilizer is not required to be changed. Therefore, the equipment is simple, and the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of controlled-release fertilizer production, and in particular relates to an anti-floating treatment method and device for a coated controlled-release fertilizer. The controlled-release fertilizer treated by the method is particularly suitable for popularization and application in rice, lotus, fish ponds and the like. Background technique [0002] Controlled-release fertilizer can basically synchronize with crop nutrient absorption through the regulation of nutrient release rate, which can greatly increase the utilization rate of fertilizer nutrients, improve the quality of agricultural products, and reduce agricultural non-point source pollution, which meets the requirements of the national sustainable development strategy. Therefore, slow control Fertilizer release has become one of the main directions for the development of the fertilizer industry in the 21st century. At present, the superior performance ...
