Abstract

Provided is a pretreatment container for discharging of a secondary battery used in the process of processing discharging of a secondary battery, in which a first upper plate and a second upper plate are rotatably disposed in a staggered manner on an upper side of a housing including a receiving space receiving a waste battery, thereby preventing the waste battery from floating during the discharging process.

First claim

What is claimed is:

1 . A pretreatment container for discharging of a secondary battery, the pretreatment container comprising:
a housing having an open upper side and including a receiving space receiving a waste battery; an upper plate including a first upper plate and a second upper plate located on an upper side of the housing and disposed in a staggered manner; and a door provided on one side of the housing and able to be opened and closed.

2 . The pretreatment container of claim 1 , wherein
coupling surfaces of the first upper plate and the second upper plate coupled to the housing are disposed to face each other.

3 . The pretreatment container of claim 2 , wherein
a length L 1 of the first upper plate is greater than a length L 2 of the second upper plate, and an inclination angle A 1 of the first upper plate is smaller than an inclination angle A 2 of the second upper plate.

4 . The pretreatment container of claim 3 , wherein
the lengths of the first upper plate and the second upper plate are determined by Equation 1 below.
L 1 cos A 1+ L 2 cos A 2> L 3  Equation 1

wherein L 1 is the length of the first upper plate, L 2 is the length of the second upper plate, L 3 is the length of the receiving space of the opened housing in the width direction, A 1 is the inclination angle of the first upper plate, and A 2 is the inclination angle of the second upper plate.

5 . The pretreatment container of claim 1 , wherein
the first upper plate and the second upper plate are rotatably hinged to the housing, and the housing includes a restraining portion protruding from an inner surface below a coupling portion at which the first upper plate and the second upper plate are hinged to the housing.

6 . The pretreatment container of claim 2 , wherein
the first upper plate and the second upper plate are rotatably hinged to the housing, and the housing includes a restraining portion protruding from an inner surface below a coupling portion at which the first upper plate and the second upper plate are hinged to the housing.

7 . The pretreatment container of claim 3 , wherein
the first upper plate and the second upper plate are rotatably hinged to the housing, and the housing includes a restraining portion protruding from an inner surface below a coupling portion at which the first upper plate and the second upper plate are hinged to the housing.

8 . The pretreatment container of claim 4 , wherein
the first upper plate and the second upper plate are rotatably hinged to the housing, and the housing includes a restraining portion protruding from an inner surface below a coupling portion at which the first upper plate and the second upper plate are hinged to the housing.

9 . The pretreatment container of claim 5 , wherein
an insertion portion through which the waste battery is inserted into the receiving space of the housing is defined between a free end of the first upper plate and a free end of the second upper plate which are disposed in a staggered manner.

10 . The pretreatment container of claim 1 , wherein
the housing includes a plurality of holes allowing the receiving space to communicate with the outside.
