The present invention relates to a superabsorbent polymer hydrogel mincing device using a pump for uniformly mincing hydrogel.
background
[4]
Super Absorbent Polymer (SAP) is a synthetic polymer material that can absorb water 500 to 1,000 times its own weight. Material), etc., are named differently. The superabsorbent polymer as described above has started to be put to practical use as a sanitary tool, and now, in addition to hygiene products such as paper diapers for children, a soil repair agent for gardening, a water-retaining material for civil engineering and construction, a sheet for seedlings, a freshness maintenance agent in the food distribution field, and It is widely used as a material for poultice, etc.
[5]
The hydrogel or hydrogel polymer obtained through the polymerization reaction as described above is generally marketed as a powdery product after being pulverized through a drying process. In order to efficiently proceed with the drying step as described above, it is important to increase the surface area of ​​the hydrogel polymer as much as possible. Therefore, in order to increase the surface area of ​​the hydrogel polymer before the drying process, a method of increasing the surface area of ​​the hydrogel polymer to be dried by simply pulverizing the hydrogel polymer polymerized through thermal polymerization or photopolymerization may be considered. In order to increase the surface area of ​​the hydrogel polymer as described above, a process of firstly pulverizing the hydrogel polymer after polymerization is disclosed.
[6]
A chopper is mainly used in the first crushing process of the hydrogel.
[7]
This chopper includes a screw for moving the hydrogel, a barrel including a spiral, a cutter blade for cutting the hydrogel, and a perforated plate through which the cut hydrogel is discharged.
[8]
In this conventional chopper, the movement direction of the hydrogel particles input to the barrel and the screw is horizontal. Therefore, there is a problem in that the pressure applied to the hydrogel particles is not uniform at the position where the perforated plate is arranged, and the working pressure is greater at the lower position of the barrel than at the upper position, so that uniform shredding is not made in the perforated plate.
[9]
As such, when the size of the chopped particles of the hydrogel is not uniform, non-uniform drying may occur for each particle in the drying process of the hydrogel, and excessive drying or non-drying may be formed.
[10]
Here, excessive drying of the hydrogel may generate a lot of fine powder in the manufacturing process of the super absorbent polymer, which may cause problems in the manufacturing process. In addition, the undried product of the hydrogel has a problem in that it is difficult to smoothly prepare the superabsorbent polymer in a process such as pulverization or classification as well as the physical properties of the superabsorbent polymer.
