Abstract
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 below a 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 belt is 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
The present invention relates to phosphate fertilizer, relate in particular to the boracic diammonium phosphate, relate in particular to the packaging method of its product.
Background technology
The boracic diammonium phosphate product is a kind of fertilizer that multiple nutrient can be provided for farm crop.Because borax at high temperature loses crystal water, product is put into the loose storehouse of finished product and is stored up temporarily after cooling, temperature are 40 ℃～55 ℃, naturally cool to normal temperature in the diammonium phosphate product production process of boracic.This moment, the boracic diammonium phosphate product can attract airborne moisture filling up the crystal water that loses, and in absorbing moisture process, and product surface easily gets damp again, thinning, strength degradation, very easily caking.Stack after for some time, product can't in bulk or packing, causes damage.Traditional solution one is to remove the airborne moisture of storehouse with dehumidifier; The 2nd, reduce and to store up the time, produce as early as possible rear packed and transported and go out, but this can only guarantee that the product short period of time do not get damp again, Zhongdao user uses on hand, also have significant period of time, how to solve anti-moisture regain and the anti-caking of product, be a technical barrier always.
Through retrieval, relate to only the having of phosphorus ammonium parcel No. 200510003301.0 " a kind of parcel of diammonium phosphate product and method of cooling " and No. 200810119314.8 " preparation method of microencapsulated ammonium polyphosphate " in the Chinese patent database, there is no and relate to the technical scheme of wrapping up the boracic diammonium phosphate product.
Summary of the invention
The purpose of this invention is to provide the moistureproof method of a kind of boracic diammonium phosphate product parcel, to reach the purpose that solves the anti-moisture regain of boracic diammonium phosphate product and anti-caking.
The contriver finds the crux of problem to be by repeatedly studying, testing: if the outside surface that has solved product pellet not with contact with moisture, just can not produce suction moisture regain phenomenon; Product is just stacked and is not had the moisture regain phenomenon, and product strength more can not lump a little less than can not falling yet.The solution route that provides thus is that through screening, the contriver adopts the talcum powder of anti-suction as lapping at the wrap of outside surface parcel one deck waterproof of product.As long as the product pellet outside is parcel one deck talcum powder evenly, make product pellet and air isolated, have no way of absorbing moisture, also just solved the problem of product protection against the tide.And the contriver is through exploration discovery, and the talcum powder of interpolation should not be more, too much affect the total nutrient of product; Cross the effect that does not reach at least parcel, and the product pilling up time is a little slightly long, and the moisture regain phenomenon is still arranged.Test many times through the contriver, determine to add talcous amount and be advisable with 3～3.5kg/t.
The concrete grammar that the contriver provides comprises the steps:
⑴ determine addition
Calculate the talcum powder total amount of required interpolation according to product yield meter hourly, as shown in the formula calculating:
G=W×(3～3.?5)kg/t
G is the talcum powder amount of required interpolation in the formula,
W is that the product belt claims the output that shows number;
(2) the boracic diammonium phosphate fresh prod of producing is sent into parcel cylinder front end, will be wrapped up simultaneously oil and add the parcel cylinder, make parcel oil and the abundant mixing of product pellet, stick to the product pellet surface;
(3) in advance packed talcum powder is pitched the production scene from storehouse, unpack rear storage and enter feed bin; Open feed bin lower plugboard valve during use, talcum powder flows down from feed bin, opens the worm conveyor under the rotary conveyor again, and worm conveyor is transported to product parcel cylinder middle part from the parcel tube rear end with talcum powder, evenly mix with the product pellet that adheres to parcel oil, be wrapped in particle surface;
(4) observe the parcel effect by frequency transformer and the push-pull valve aperture of regulating rotary conveyor, until the belt on the rotary conveyor claims till the add-on G that quantity is shown as calculating.
Above-mentioned talcum powder is commercially available finished product, and its fineness is 100 orders.
Above-mentioned parcel oil is the commercially available special-purpose oily 4054SAC of parcel of diammonium phosphate or machinery oil, and its add-on is controlled to be 1 kg/h.
The inventive method has broken through existing technique for packing, has solved protection against the tide and this a great problem of anti-caking of the diammonium phosphate product that adds boron, has also solved packing and the transportation problem of boracic diammonium phosphate product simultaneously.Be applicable to produce the producer that adds boron phosphate fertilizer product.
Description of drawings
Fig. 1 is the schematic flow sheet of the inventive method.1 for belt claims among the figure, and 2 are the rotary conveyor with the frequency transformer adjusting; 3 is feed bin; 4 is push-pull valve; 5 is worm conveyor; 6 are the parcel cylinder.
Embodiment
Embodiment
Two series of Wengfu Group Co., Ltd.'s diammonium phosphate device all adopt this technique to carry out the parcel of boracic diammonium phosphate product, and specific practice is as follows:
Determine first addition: adding talcous amount according to product per ton is 3～3.5kg/t, extract the display data that belt claims on the belt out by product, calculate the talcous total quantity of required interpolation, be 75t/h by output, calculate the talcous total amount of required interpolation and be: the 5=265kg/h of G=75 * 3.;
Boracic diammonium phosphate 75t/h fresh prod is sent into parcel cylinder front end, and the flow according to 7.5kg/h adds the parcel cylinder with the oily 4054SAC of the special-purpose parcel of diammonium phosphate simultaneously, makes parcel oil and the abundant mixing of product pellet, sticks to the product pellet surface;
Be that 100 purpose talcum powder are pitched the production scene from storehouse in advance with packed fineness, unpack rear storage and enter feed bin; Open feed bin lower plugboard valve during use, talcum powder flows down from feed bin, opens the worm conveyor under the rotary conveyor again, and worm conveyor is transported to product parcel cylinder middle part from the parcel tube rear end with talcum powder, evenly mix with the product pellet that adheres to parcel oil, be wrapped in particle surface;
Observe the parcel effect by frequency transformer and the push-pull valve aperture of regulating rotary conveyor, until till the add-on G that the belt on the rotary conveyor claims quantity to be shown as calculating is 265kg/h, finally reach the parcel effect.
This technology obtains obvious operating performance and economic benefit after using through urn good fortune (group) company diammonium phosphate device.
