Abstract

Disclosed is a hydrogel shredding device. The hydrogel shredding device includes: a first barrel body in which a first transfer space for transferring a hydrogel is formed, and extending in a first direction; a first transfer unit installed in the first barrel body and transferring the hydrogel in the first transfer space; a second barrel body installed on a lateral side of the first barrel body, and in which a second transfer space connected to the first transfer space extends in a second direction traversing the first direction; a second transfer unit installed in the second barrel body and transferring the hydrogel in the second transfer space; a cutter member installed in the second barrel body and pulverizing the hydrogel transferred by the second transfer unit; and a porous plate for discharging the hydrogel particles pulverized by the cutter member to an outside of the second barrel body.

First claim

The invention claimed is:

1. A hydrogel shredding device comprising:
a first barrel body in which a first transfer space for transferring a hydrogel is formed to extend in a first direction;
a first transfer unit installed on the first barrel body, configured to transfer the hydrogel in the first transfer space;
a second barrel body installed on a lateral side of the first barrel body, and in which a second transfer space connected to the first transfer space extends in a second direction traversing the first direction;
a second transfer unit installed in the second barrel body, configured to transfer the hydrogel in the second transfer space;
a cutter member installed in the second barrel body, configured to pulverize the hydrogel transferred by the second transfer unit, to form pulverized hydrogel particles;
a porous plate for discharging the pulverized hydrogel particles to an outside of the second barrel body; and wherein the second barrel body is rotatably installed on the first barrel body by a driver.

2. The hydrogel shredding device of claim 1 , wherein
a first moving space in which hydrogel particles move is formed in the first barrel body, and an input unit for inputting the hydrogel particles is formed on an upper portion of the first barrel body.

3. The hydrogel shredding device of claim 2 , wherein
the first transfer unit includes
a first screw member rotatably installed inside the first transfer space, configured to move the hydrogel, and
a first driving motor configured to provide a rotation driving force to the first screw member.

4. The hydrogel shredding device of claim 3 , wherein
the second barrel body is installed on a lateral side of the first barrel body, a second moving space connected to the first transfer space is formed in a top to bottom direction, and an outlet for discharging pulverized hydrogel particles is formed on a lower portion.

5. The hydrogel shredding device of claim 4 , wherein
the second transfer unit includes
a second screw member rotatably installed in the second transfer space, configured to transfer the hydrogel input through the first transfer space in a direction of the outlet, and
a second driving motor installed in the second barrel body, configured to provide a rotation driving force to the second screw member.

6. The hydrogel shredding device of claim 5 , wherein
the cutter member is rotatably installed in the second screw member at a position of the outlet.

7. The hydrogel shredding device of claim 6 , wherein
the first driving motor and the second driving motor have different drive shaft rotation speeds.

8. The hydrogel shredding device of claim 7 , wherein
a plurality of the cutter members are installed in the second screw member.

9. The hydrogel shredding device of claim 1 , wherein
the driver is installed on the first barrel body, and a load member of the driver rotatably installed on a lateral side of the second barrel body.

10. The hydrogel shredding device of claim 9 , wherein
a cover member is installed around a connection position of the first barrel body and the second barrel body.
