Abstract

A cold trap includes: a main body connected to an exhaust line between a vacuum dryer and a vacuum pump; a trap portion installed in the main body and that freezes evaporated steam supplied from the vacuum dryer; and an insulation portion installed between the main body and the trap portion and that blocks cold of the trap portion from being conducted to the main body.

Claims

1. A cold trap, comprising:

a main body connected to an exhaust line between a vacuum dryer and a vacuum pump;

a trap portion installed in the main body and that freezes evaporated steam supplied from the vacuum dryer; and

an insulation portion installed between the main body and the trap portion and that blocks cold of the trap portion from being conducted to the main body.

2. The cold trap of claim 1, further comprising a heat discharge unit formed at an upper portion of a side wall of the main body and for discharging a heat existing at an internal space of the main body to the outside,

wherein the heat discharge unit comprises:

a base having an installation space therein; and

a plurality of discharge induction portions formed at a gap in a vertical direction of the installation space to form a heat discharge passage therebetween, and

wherein the discharge induction portion has a tilt angle gradually receding from the internal space of the main body, as advancing from a lower portion to an upper portion in order to enhance discharge efficiency of a heat.

3. The cold trap of claim 2, wherein in the insulation portion and the main body, a plurality of fastening holes connected in a vertical direction while being penetrated in a vertical direction are each formed, and

wherein the cold trap further comprises a pressing fixing portion that comes in close contact with the main body by pressing the insulation portion while being sequentially fastened to the fastening hole of the insulation portion and the fastening hole of the main body.

4. The cold trap of claim 2, wherein at an upper surface of the main body, an insertion groove separated at a predetermined gap along an edge of the first receiving hole is formed,

wherein the cold trap further comprises:

a rotation portion rotatably connected in a vertical direction along an edge of the insulation portion; and

a fixing portion configured with an insertion protrusion formed at a bottom surface of the rotation portion and inserted into the insertion groove, when the rotation portion rotates in a lower direction,

wherein the rotation portion is formed in a step shape or a wave shape.

5. The cold trap of claim 1, wherein the main body has a first receiving hole penetrated in a vertical direction at an upper surface,

the insulation portion has a second receiving hole penetrated in a vertical direction and is received at an upper surface of the main body such that the second receiving hole is positioned on a vertical line of the first receiving hole, and

an upper edge of the trap portion is received at an upper surface of the insulation portion while the trap portion is received in the first receiving hole and the second receiving hole.

6. The cold trap of claim 3, wherein in the insulation portion and the main body, a plurality of fastening holes connected in a vertical direction while being penetrated in a vertical direction are each formed, and

wherein the cold trap further comprises a pressing fixing portion that comes in close contact with the main body by pressing the insulation portion while being sequentially fastened to the fastening hole of the insulation portion and the fastening hole of the main body.

7. The cold trap of claim 3, wherein at an upper surface of the main body, an insertion groove separated at a predetermined gap along an edge of the first receiving hole is formed,

wherein the cold trap further comprises:

a rotation portion rotatably connected in a vertical direction along an edge of the insulation portion; and

a fixing portion configured with an insertion protrusion formed at a bottom surface of the rotation portion and inserted into the insertion groove, when the rotation portion rotates in a lower direction,

wherein the rotation portion is formed in a step shape or a wave shape.

8. The cold trap of claim 1, wherein in the insulation portion and the main body, a plurality of fastening holes connected in a vertical direction while being penetrated in a vertical direction are each formed, and

wherein the cold trap further comprises a pressing fixing portion that comes in close contact with the main body by pressing the insulation portion while being sequentially fastened to the fastening hole of the insulation portion and the fastening hole of the main body.

9. The cold trap of claim 1, wherein at an upper surface of the main body, an insertion groove separated at a predetermined gap along an edge of the first receiving hole is formed,

wherein the cold trap further comprises:

a rotation portion rotatably connected in a vertical direction along an edge of the insulation portion; and

a fixing portion configured with an insertion protrusion formed at a bottom surface of the rotation portion and inserted into the insertion groove, when the rotation portion rotates in a lower direction,

wherein the rotation portion is formed in a step shape or a wave shape.
