Fast door opening and closing device and door opening and closing method for impregnating tank

Abstract

The invention discloses a fast door opening and closing device and a door opening and closing method for an impregnating tank. The fast door opening and closing device comprises a tank body, a moving mechanism and an end cover, wherein a rotating ring is arranged on the outer side of the end part of the tank body, a NO.1 mounting base and a NO.2 mounting base are respectively arranged at the upper part and the lower part of the rotating ring, a piston rod of an upper oil cylinder is hinged with the NO.1 mounting base by a NO.1 connecting shaft, and the tail end of the upper oil cylinder is hinged with a connecting frame by a NO.2 connecting shaft; the tail end of a lower oil cylinder is hinged with the connecting frame by a NO.3 connecting shaft, and a piston rod of the lower oil cylinder is hinged with the NO.2 mounting base by a NO.4 connecting shaft; the connecting frame is arranged on the tank body, the end covers are arranged on two sides of the tank body, the outer sides of the end covers are arranged on the moving mechanism, and wedge-shaped outer teeth are arranged on the outer ends of the inner sides of the end covers; and wedge-shaped inner teeth are arranged at the outer side of the rotating ring. With the structure, the fast door opening and closing device has the advantages and effects that a door can be opened and closed fast, the airtightness property is good when the door is closed, the productivity is improved, and the labor intensity of workers can be reduced.

Description

technical field [0001] The invention relates to a quick door opening and closing device, in particular to a quick opening and closing door and a device opening and closing method for impregnation tanks in industries such as carbon and metallurgy. Background technique [0002] In order to increase the density of carbon products including graphite electrodes, aluminum cathodes and special carbon, reduce porosity penetration, increase the mechanical strength of products and improve electrical conductivity and thermal conductivity, dipping tank devices are often used to infiltrate high-temperature and high-pressure liquid pitch into products. in the gap. In the prior art, there are many ways to open and close the mouth of the dipping tank, such as the rack and pinion type, the flange type, and the opening and closing oil cylinder for the mouth of the tank. The shaft is connected with the tank body, and an opening and closing oil cylinder and the like are connected between the ...

AI Technical Summary

Problems solved by technology

The mouth opening and closing mechanisms of these impregnating tanks generally have disadvantages such as complex structure, difficult operation and large amount of maintenance.
