A self-locking safety door for a rotary pressure vessel

Abstract

The invention relates to the field of pressure equipment, in particular to a self-lock safety door of a rotary pressure vessel. The self-lock safety door of the rotary pressure vessel comprises a pressure vessel body and a vessel door arranged on the opening of the pressure vessel body, a fixed connecting ring is arranged on the opening of the pressure vessel body, the pressure vessel body or the fixed connecting ring is connected with the center of the vessel door through a hinge component, a rotating shaft which the vessel door rotates around is arranged at the joint between the center of the vessel door and the hinge component, more than one pair of lock catch and lock groove matched with each other is arranged on the fixed connecting ring and vessel door, a first lock hole is formed in the side wall of the vessel door, a second lock hole corresponding to the first lock hole is formed in the fixed connecting ring, and a safety pin which moves along the first lock hole and second lock hole is arranged in the first lock hole. When working, the safety pin is jacked up and fixed by means of pressure difference, the safety pin falls off to release fixing under the gravity, the pressure vessel can be opened through rotating the vessel door, the operation is facilitated, and the problem of low production efficiency due to too long door opening and closing time is solved.

Description

technical field [0001] The invention relates to the field of pressure equipment, in particular to a self-locking safety door of a rotary pressure vessel. Background technique [0002] In the field of pressure equipment, the container door as a pressure vessel must have good sealing and firmness, whether it is a pressure vessel in a positive pressure state when the pressure inside the container is greater than the external pressure, or the pressure inside the container is lower than the external pressure. In the case of pressure, that is, the pressure vessel in the negative pressure state has high requirements for the sealing and firmness of the vessel door. The existing pressure vessel uses fixing bolts to fix the vessel door. According to the size of the vessel door and The pressure in the pressure vessel is distributed with multiple bolts around the container door. Although this method meets the requirements of sealing and firmness, the opening and closing time of the seal...
