Abstract
The present invention discloses a kind of packing method of liquid fertilizer; this method is first to use rigidity and flexible double packing material while packed; protected after packaging by the way of nitrogen charging, and install one-way check valve be used for discharge because of the bulbs of pressure caused by liquid fertilizer activity；The rigid package substrate is the Plastic Drum with bung；Flexible package thing is the good sealed polyethylene plastic inner bag of malleable.Using the liquid fertilizer of the method packaging production of the present invention, the phenomenon of swollen bucket and liquid fertilizer leakage will not occur during accumulating use, reduce the economic loss caused by swollen bucket and Liquid Fertilizer leak, improve the item property of product again, received by market.Therefore, packing method of the invention can be widely used for the packaging of the unstable liquid form product of similarity, have certain application value.
Description
Technical field：
The present invention relates to liquid fertilizer technical field, more particularly to a kind of packing method of liquid fertilizer.
Background technology：
At present, liquid fertilizer on the market can be divided into two kinds of rigid package and flexible package according to packaged form.Just
Property packaging is more is used as packing material using the rigid plastics bucket with some strength, flexible package is more using having certain malleable
Plastic film bag is as packing material.But either rigid package or flexible package, it can not all avoid because Liquid Fertilizer is intrinsic not
Many disadvantages such as swollen quick-fried bag of bucket caused by stability activity characteristic, the liquid fertilizer especially produced using biogas slurry as mother liquor,
After barrel filling pack packaging, because of the aerobic bacteria remained in biogas slurry, during accumulating use, the Liquid Fertilizer in packing material is residual at these
Thermophilic oxygen animalcule is still among activity in the presence of the aerobic bacteria stayed, can produce a small amount of gas, and these gases are relative
Accumulation to a certain extent, possesses the energy for being enough to make packaging material deform so as to be formed, makes packing material in airtight package body
Volumetric expansion, destroy the sealing of package body, phenomena such as such as swollen bucket, broken bag occur, cause Liquid Fertilizer to overflow, liquid fertilizer
The production of material, accumulating, using making troubles, destroy the item property of liquid fertilizer product to a certain extent, constrain liquid
Fertilizer is promoted the use of.Therefore, applicant is by analyzing the existing deficiency in terms of packaging of liquid fertilizer on the market,
And liquid fertilizer characteristic is combined, develop a kind of packing method of the liquid fertilizer of new rigid flexible system.
The content of the invention：
The problem of in order to overcome prior art to exist, it is contemplated that the characteristic for liquid fertilizer, there is provided a kind of liquid
The packing method of fertilizer, the deficiencies of overcoming swollen bucket existing for existing packing method, quick-fried bag, leak.
In order to solve the above technical problems, the present invention takes following technical scheme：
A kind of packing method of liquid fertilizer, it is first to use rigidity and flexible double packing material while packed, and is wrapped
Protected after installing by the way of nitrogen charging, and install one-way check valve be used for discharge because caused by liquid fertilizer activity expand
Pressure.
Above-mentioned rigid package substrate is the Plastic Drum with bung, and flexible package thing is that the good vinyon of malleable is thin
Film inner bag.
Further, it is in Liquid Fertilizer batch can packaging to be carried out to liquid fertilizer simultaneously using rigidity and flexible double packing material
During dress production, in Plastic Drum liner layer of plastic film inner bag, Liquid Fertilizer is filled into plastic sheeting inner bag, then is pricked with band
Sack in tight plastic sheeting, and discharge mixed air in plastic sheeting inner bag as far as possible in tying, to ensure at Liquid Fertilizer
In the state of relatively hypoxia.
Further, when it is in liquid fertilizer canned production that protection is carried out by the way of nitrogen charging, in Plastic Drum and plastics
Plastic drum lid is compressed again after being filled between the space of film inner bag with nitrogen, to ensure that Liquid Fertilizer packaging atmosphere in the tub is relatively lean.
Further, the inlet non return check valve of installation is located at plastic drum lid middle position.Although using rigidity and flexible double
Packing material is packed simultaneously, and is protected by the way of nitrogen charging, but still is difficult to ensure that in Liquid Fertilizer package body and is in
Under absolute vacuum state, a certain amount of oxygen-containing air can be still remained in plastic sheeting inner bag, this partial air can still activate accumulating
During thermophilic oxygen animalcule in Liquid Fertilizer, and then produce volumetric expansion, increase pressure in Liquid Fertilizer pail pack, destroy packing material
Air-tightness.Therefore, an inlet non return check valve is installed, when pressure reaches to a certain degree in bucket, inlet non return check valve can automatically turn on
Pressure in bucket is discharged, and is closed automatically after pressure release in bucket.
The beneficial effects of the present invention are：Using the liquid fertilizer of the method packaging production of the present invention, used in accumulating
The phenomenon of swollen bucket and liquid fertilizer leakage will not occur in journey, that is, reduce the economic damage caused by swollen bucket and Liquid Fertilizer leak
Lose, improve the item property of product again, received by market.Therefore, packing method of the invention can be widely used for similarity
The packaging of the unstable liquid form product of matter, there is certain application value.
Embodiment：
Technical scheme is described in detail with reference to embodiment.
Embodiment 1
Product：Liquid fertilizer containing biogas slurry
Packing material：Rigidity and flexible double packing material, wherein：Rigid package substrate is Plastic Drum, and flexible package thing is plastics
Film inner bag.
Packaging process：
1) liquid fertilizer containing biogas slurry is in canned production, first in Plastic Drum liner layer of plastic film inner bag, by the liquid
Body fertilizer is filled into plastic sheeting inner bag, then tightens sack in plastic sheeting with band, and discharges plastic sheeting in tying
Mixed air in inner bag；
2) between the space of Plastic Drum and plastic sheeting inner bag, after being filled with nitrogen, then plastic drum lid is compressed；
3) one inlet non return check valve is installed in plastic drum lid middle position, when pressure reaches to a certain degree in bucket, unidirectionally
Non-return valve automatically turns on pressure in release bucket, and is closed automatically after pressure release in bucket.
The liquid fertilizer containing biogas slurry packed using above packing method, the operation letter packed in actual production process
Single, quick, during accumulating and use, the sealing of double casing thing is higher, and liquid fertilizer will not overflow, and especially be mounted with
The inlet non return check valve opened and closed automatically, it is released the pressure in bucket, so as to completely avoid swollen bucket, broken bag phenomenon
While generation, economic loss is decreased, improves the item property of product.Such as various liquid fertilizers, and similarity
The method that the packaging of the unstable liquid form product of matter can use the present invention, can be by wide popularization and application.
Preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included within the scope of the present invention with principle.
