Large diaminodiphenyl ether sublimation kettle

Abstract

The invention discloses a large diaminodiphenyl ether sublimation kettle. The large diaminodiphenyl ether sublimation kettle comprises a sublimation tank body, a crystallizing tank, a silicone rubber box, a vacuum pump and a connecting pipe, wherein the sublimation tank body comprises a feeding hole, a discharge hole, heating pipes, a heating barrel, a fixing frame, a temperature sensor, a feeding cover, a discharge cover and a main tank, the feeding hole is formed at the outer side of the top end of the main tank, the heating pipes are arranged on the inner surface of a main tank body and wind the main tank body, the heating barrel wraps the middle-lower part of the main tank, an oil inlet is formed on the side surface of the top part of the heating barrel, an oil outlet is formed at the bottom of the heating barrel, the fixing frame is arranged on the outer side of the heating barrel, the temperature sensor is inserted into and extends to the bottom of the main tank from the top part of the main tank, and the crystallizing tank inclines and forms an included angle of 30-60 degrees with the ground. The large diaminodiphenyl ether sublimation kettle has the advantages that a feeding funnel is used for feeding a material into the feeding hole directly, and workers are not required to be in contact with the material; the heating pipes and the heating barrel are used for heating simultaneously, so that a rapid heating effect is achieved, the production efficiency is improved and labor is saved; besides, the crystallizing tank is arranged obliquely, and an upper cover and a lower cover of the crystallizing tank can be rapidly opened, so that products can be conveniently collected.

Description

technical field [0001] The invention relates to a large diaminodiphenyl ether sublimation kettle, belonging to the fine chemical industry, in particular to a device for producing diaminodiphenyl ether through sublimation. Background technique [0002] The existing diaminodiphenyl ether sublimation kettle is a multi-tube sublimation kettle in the abdominal cavity, and multiple tubes can be placed in the abdominal cavity, and a silica gel box is arranged at the end of each tube to absorb impurities in the sublimation process. Production needs to manually add raw materials to the tube, and manually disassemble the silica gel box to replace the silica gel. The output is low and labor-intensive. The crystallization chamber is placed flat, which makes it inconvenient to collect products. Because workers need to directly contact materials, it will cause certain harm to the health of workers. Contents of the invention [0003] The object of the present invention is to provide a l...
