Embodiment
[0020] Both series of diammonium phosphate plants of Wengfu (Group) Co., Ltd. adopt this process to wrap boron-containing diammonium phosphate products. The specific methods are as follows:
[0021] First determine the amount of talcum powder added: According to the amount of talcum powder added per ton of product is 3 ~ 3.5kg / t, according to the display data on the belt scale on the belt that the product is pulled out, calculate the total amount of talcum powder that needs to be added, and the output is 75t / h meter, calculate the total amount of talcum powder needed to be added as: G=75×3.5=265kg / h;
[0022] Feed the boron-containing DAP 75t / h fresh product into the front end of the wrapping cylinder, and at the same time add the DAP special wrapping oil 4054SAC into the wrapping barrel according to the flow rate of 7.5kg / h, so that the wrapping oil and product particles are fully mixed and adhered to the product particle surface;
[0023] The bagged talcum powder with a f...

The invention discloses a wrapping moisture-proof method for a diammonium borophosphate-containing product. In the method, the external surface of the diammonium borophosphate-containing product is wrapped with a layer of waterproof wrapping substance which is water absorption preventing talcpowder. The method comprises the following steps of: determining addition amount; conveying the produced diammonium borophosphate-containing fresh product to the front end of a wrapping barrel, adding wrapping oil into the wrapping barrel, and ensuring that the wrapping oil is fully and uniformly mixed with product particles and adhered to the surfaces of the product particles; opening a bin, feeding a gate valve, making the pre-stored talcpowder flow down from the bin, starting a screw conveyer belowa belt conveyer, conveying the talcpowder from the rear end of the wrapping barrel to the middle part of the product wrapping barrel by using the screw conveyer, and ensuring that the talcpowder is uniformly mixed with the product particles to which the wrapping oil is adhered and is wrapped on the surfaces of the particles; and observing a wrapping effect until a number displayed by a weigh beltis the calculated addition amount. By the method, the problems of packaging and transporting of the diammonium borophosphate-containing product are solved; and the method is suitable for manufacturers for producing boron-added phosphorus fertilizer products.
Description
technical field [0001] The invention relates to phosphate fertilizers, in particular to boron-containing diammonium phosphate, and especially to a wrapping method for its products. Background technique [0002] Boron-containing diammonium phosphate product is a fertilizer that can provide various nutrients for crops. During the production process of boron-containing diammonium phosphate products, because borax loses crystal water at high temperature, the products are cooled to a temperature of 40°C to 55°C, and then put into the warehouse of finished products for temporary storage, and naturally cooled to room temperature. At this time, the boron-containing diammonium phosphate product will attract moisture in the air to fill the lost crystal water, and in the process of absorbing moisture, the surface of the product is easy to regain moisture and become thinner, the strength decreases, and it is easy to agglomerate. After stacking for a period of time, the products cannot ...
