Description

Flange heating jacket Technical Field The application relates to the field of flanges, in particular to a flange heating jacket. Background Melt conveying is a key device of a polyester device, and mainly used for conveying a solution or a melt and keeping a certain temperature, in particular to conveying a high-temperature melt. However, since the transfer pipe is long and has an elbow, a flange is required to be connected, and in order to keep the flange at a certain temperature to prevent the melt from cooling and solidifying, a flange heating jacket is required to heat the flange. The existing flange heating jacket is used for heating the side wall of the flange in a circle by sleeving the flange, but in the heating process, the upper surface and the lower surface of the flange are too fast to dissipate heat, so that the temperature of a pipeline connecting position is low and local cold points are caused, and the applicability is reduced. Disclosure of utility model In order to solve the problems, the application provides a flange heating jacket. The flange heating jacket provided by the application adopts the following technical scheme: The utility model provides a flange heating presss from both sides cover, includes two arc splint, two the relative one side lateral wall fixedly connected with hot plate of arc splint, two arc splint one end articulates mutually, is equipped with the fixed subassembly that is used for the installation and is used for preventing the seal assembly that heat looses on two arc splint, seal assembly includes a plurality of fixed connection arc splint inside wall is located the elastic sealing pad of hot plate both sides, the equal fixedly connected with fixed plate of both sides lateral wall at arc splint both ends, fixed plate one side lateral wall with elastic sealing pad fixed connection, every two be equipped with the elastic connection board between the fixed plate, the elastic connection board both ends run through respectively the fixed plate and form the slip setting, elastic connection board one side lateral wall with elastic sealing pad fixed connection is equipped with coupling assembling on the elastic connection board.
