Description

Изобретение относитс  к устройствам дл  непрерывной кристаллизационной очистки органических веществ.The invention relates to devices for the continuous crystallization purification of organic substances.

Известно устройство дл  непрерывной кристаллизационной очистки органических веществ, состо щее из емкости, выполненной в форме конуса со штуцерами, и теплообменника , охватьтающего всю конусообразную поверхность емкости. В таком устройстве при нарушении температурного режима процесса по вл етс  возможность загр знени  oчищeннoгo Jвeщecтвa путем проникновени  последнего между стенкой емкости и слитком ъ зону очищенного веществаA device for continuous crystallization purification of organic substances is known, consisting of a vessel made in the form of a cone with fittings and a heat exchanger that covers the entire conical surface of the vessel. In such a device, if the temperature of the process is disturbed, it becomes possible to contaminate the cleaned organic matter by penetrating the latter between the vessel wall and the ingot in the zone of the purified substance.

В предлагаемом устройстве дл  получени  продукта выссжой степени чистоты внутренн   поверхность конуса имеет кольцевую риску произвольного профил , удаленную от фронта кристаллизации на рассто ние , определ емое структурой продукционных кристаллов,In the proposed device for obtaining a product of high purity, the inner surface of the cone has an annular risk of an arbitrary profile remote from the crystallization front for a distance determined by the structure of production crystals

На чертеже изображено предлагаемое устройство.The drawing shows the proposed device.

на внутренней конической поверхности которого имеетс  кольцева  риска 7, и теплообменник 8, охватывающий всю конусообразную поверхность емкости 1.on the inner conical surface of which there is an annular risk 7, and a heat exchanger 8, covering the entire conical surface of the tank 1.

Устройство работает следующим образом.The device works as follows.

В период пуска через штуцер 2 емкость 1 заполн ют охлажденным очищенным веществом , теплообменник 8 включают на режим работы холодильника, внос т, при необходимости , кристаллическую затравку и кристаллизуют, получа  конусообразный кристаллический слиток 9, который имеет фронт кристаллизации 1О и поверхность плавлени  11. На получении слитка заканчиваетс  пусковой период устройства.During start-up through fitting 2, tank 1 is filled with cooled purified substance, heat exchanger 8 is turned on for refrigerator operation mode, if necessary, crystallized and crystallized, obtaining a conical crystalline ingot 9 that has a crystallization front 1O and melting surface 11. when the ingot is produced, the starting period of the device ends.

После этого всю систему заполн ют очищаемым веществом. Теплообменник 8 переключают на режим работы нагревател  и включают циркул ционный насос (начертеже не показан). Очищаемое вещество пропускаю через холодильник, охлаждают до определенной температуры и через штуцер 4 емкости 1 поток его направл ют по поверхности фронта кристаллизации Ю слитка 9, где оно и кристаллизуетс . Примеси, вытесн емые вAfter that, the entire system is filled with the substance to be purified. The heat exchanger 8 is switched to the heater operation mode and a circulation pump is switched on (not shown in the drawing). The substance to be purified is passed through a cooler, cooled to a certain temperature, and through the nozzle 4 of the tank 1 its flow is directed along the surface of the crystallization front of the Yu ingot 9, where it crystallizes.
