processing container

Abstract

The utility model discloses a processing container which is provided with a box body and an opening / closing door, wherein an open part for filling refrigerant or projecting projection materials is formed on the box body; and the opening / closing door opens / closes the open part of the box body. The processing container comprises a peripheral plate, an inner door and a gasket, wherein the peripheral plate is fixed on the periphery of the open part of the box body; the inner door is mounted on the inner side surface of the opening / closing door in an elastic support state and covers the open part of the box body, and the periphery of the inner door is in close contact with the peripheral plate; and the gasket is located between the peripheral plate on the periphery of the inner door and the inner side surface of the opening / closing door to realize sealing. The processing container disclosed by the invention can efficiently prevent the gasket covering the open part of the box body and the opening / closing door in a sealing state from staying at low temperature and being damaged by hardening, can efficiently prevent the projection materials from being projected onto the gasket so as to ensure the sealing state, and thus can improve the durability of the gasket, reduce the replacing operation of the gasket and improve the operation efficiency.

Description

technical field [0001] The present invention relates to a processing container, which is a shot blasting device used for filling refrigerant into the interior, or projecting a shot while filling the refrigerant, or projecting only the shot. Background technique [0002] Conventionally, such a processing container is configured such that the opening of the box can be opened and closed by an opening and closing door, and a soft resin gasket such as silicone rubber is provided to seal the opening of the box and the opening and closing door. [0003] However, when used as a processing container filled with refrigerant or projected material, there is a disadvantage that the soft resin liner is at a low temperature due to the filled refrigerant, and it is easy to harden and be damaged, and the projected material is located until it is soft. As far as the position of the resin packing is concerned, if cleaning is not performed frequently, the soft resin packing will be damaged and ...

Problems solved by technology

[0003] However, when used as a processing container for filling the inside with refrigerant or projecting projectiles, there is a disadvantage that the soft resin liner is at a low temperature due to the filled refrigerant, and it is easy to harden and be damaged, and the projectile is located until it is soft. If cleaning is not performed frequently at the position of the resin packing, the soft resin packing will be damaged and the seal will leak.
