Abstract

The invention relates to a flange for plastic processing exhaust gas transmission. The flange is composed of a flange housing, a boss, a heating groove, a through hole, bolt holes, a ring groove, a temperature measuring hole, a wire groove, a positioning pin and a waste discharging hole. The through hole is located in the center of the flange housing; the boss, the heating groove, the positioningpin and the wire groove are located on the flange assembly surface; the height of the boss is greater than the height of the positioning pin, and the boss end face is provided with the ring groove tobe used for containing a sealing ring; the bolt holes are symmetrically distributed in the flange housing to be used for flange assembling; the heating groove is ring-shaped and is located between thethrough hole and the bolt holes; and the temperature measuring hole and waste discharging hole are arranged in the radial direction of the flange housing and are half-threaded through hole. The flange has the beneficial effect that the problems that an existing flange cannot be heated, a pipeline is blocked, waste liquid cannot be discharged, and the energy consumption is high are solved.

Description

technical field [0001] The invention belongs to the technical field of pipe connectors, in particular to a flange, and more specifically to a flange for conveying waste gas from plastic processing. Background technique [0002] Flange as the middleware of pipeline connection is a very common application of pipeline connection. Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate first, add flange pads between the two flange plates, and fasten them with bolts to complete the connection. [0003] During the plastic processing process, a large amount of waste gas is generated due to the decomposition of plastic, and the melting points of the components in the waste gas are different. Therefore, during the transportation of these waste gases, as the temperature of the pipeline gradually decreases, solidification will form on the pipe wall, especially the flange. The utility model patent with application number 201510267382.9 is a heatable flange, ...
