Abstract

A cathode material integrated processing device, which dries, applies, and heat-treats a cathode material, according to an embodiment of the invention includes a support frame, a chamber part including a cylindrical body configured to accommodate the cathode material and a thick plate coupled to each of both ends of the cylindrical body to seal both the ends of the cylindrical body and configured to fix the cylindrical body to an upper portion of the support frame, a heating part disposed in each of the outside the cylindrical body and the outside the thick plate of the chamber part to heat the chamber part, a spray part including one or more nozzles, which is disposed between an upper portion and one side of the cylindrical body of the chamber part and is inserted in a longitudinal direction of the cylindrical body to spray a coating liquid to the cathode material within the chamber part through a gas, a stirring part rotatably disposed inside the cylindrical body of the chamber part to stir the cathode material within the chamber part, a driving part connected to one side of the stirring part and rotatably disposed at one side of an upper portion of the support frame to rotate the stirring part, and a control part configured to control the heating part, the spray part, and the driving part.

First claim

What is claimed is:

1 . A cathode material integrated processing device, which dries, applies, and heat-treats a cathode material, the cathode material integrated processing device comprising:
a support frame; a chamber part including a cylindrical body configured to accommodate the cathode material and a pair of plates respectively coupled to both ends of the cylindrical body to seal both the ends of the cylindrical body and configured to fix the cylindrical body to an upper portion of the support frame; a plurality of heating parts respectively disposed outside the cylindrical body and outside each of the plates of the chamber part to heat the chamber part; a spray part including one or more nozzles, which is disposed between an upper portion and one side of the cylindrical body of the chamber part and is inserted in the cylindrical body to spray a coating liquid to the cathode material within the chamber part through a gas; a stirring part rotatably disposed inside the cylindrical body of the chamber part to stir the cathode material within the chamber part; a driving part connected to one side of the stirring part and rotatably disposed at one side of an upper portion of the support frame to rotate the stirring part; and a controller configured to control the heating part, the spray part, and the driving part, wherein the chamber part comprises:
an input part disposed on an upper portion of one side of the cylindrical body to input the cathode material into the chamber part;
an exhaust part disposed on an upper portion of another side of the cylindrical body to discharge moisture within the chamber part to the outside;
a discharge part disposed on a lower portion of the cylindrical body to discharge the cathode material to the outside of the chamber part; and
a manhole part disposed at one side of the cylindrical body to be accessible for maintenance and cleaning inside the chamber part,
wherein the manhole part comprises:
a manhole passage having one end connected to one side of the cylindrical body of the chamber part and the other end protruding out of the cylindrical body so as to be spaced apart from the chamber part;
a manhole cover having an upper portion coupled to an upper portion of the other end of the manhole passage through a hinge unit to rotate vertically, thereby opening and closing the manhole passage;
a packing inserted into an inner circumference of the manhole cover to seal a gap between the manhole passage and the manhole cover; and
a locking unit provided to correspond to each of a lower portion of the other end of the manhole passage and a lower portion of the manhole cover so as to lock the manhole cover configured to open and close the manhole passage.

2 . The cathode material integrated processing device according to claim 1 , wherein the heating part comprises an electric heating wire.

3 . The cathode material integrated processing device according to claim 1 , wherein the heating part is spaced apart from the outside of the cylindrical body.

4 . The cathode material integrated processing device according to claim 1 , wherein the locking unit comprises:
a latch provided to be rotatably upward on the lower portion of the other end of the manhole passage; and a hook part fixed to the lower end of the manhole cover so that the latch is hooked.

5 . The cathode material integrated processing device according to claim 1 , further comprising an accommodation groove bent inward to accommodate the packing in the inner circumference of the manhole cover.

6 . The cathode material integrated processing device according to claim 1 , further comprising a block inserted into the manhole passage to block accumulation of the cathode material inside the manhole passage inside the manhole cover.

7 . The cathode material integrated processing device according to claim 1 , further comprising a handle configured to hold the manhole cover so as to be fixed on the outside of the manhole cover.

8 . The cathode material integrated processing device according to claim 1 , further comprising, in the manhole part;
an inspection hole passing through the manhole cover to measure an internal temperature of the chamber part; and a plug coupled to the inspection hole so as to be opened and closed.

9 . The cathode material integrated processing device according to claim 1 , wherein a cooling unit configured to cool the manhole part is disposed in an outer circumferential surface of the manhole passage.

10 . The cathode material integrated processing device according to claim 1 , wherein the manhole passage has a length of about 200 mm to about 600 mm.
