Title
(EN) POWDER CONTAINER INVERTING DEVICE FOR HEATING FURNACE
(FR) DISPOSITIF D'INVERSION DE CONTENANT DE POUDRE POUR FOUR DE CHAUFFAGE
(JA) 加熱炉用粉体容器反転装置
Abstract
(EN)
Provided is a powder container inverting device for a heating furnace, with which it is possible to recover processed powder from a high temperature powder container. When a pair of inversion shafts (90), (92) are inverted by means of an inverting actuator provided outside an inversion chamber (62), a powder container being held by clamp devices (94), (96) fixed to chamber inside end portions of the inversion shafts (90), (92) is inverted, and powder in the powder container is removed. Since the inverting actuator and an unclamping actuator (130), which have a relatively low resistance to heat, are provided outside the inversion chamber (62), the relatively high temperature powder container can be inverted to remove the powder from inside the powder container. Further, since it is not necessary to reduce the temperature to near ambient temperature in a rear half part of the heating furnace, allowing the heating furnace to be shortened, an increase in the size of thermal equipment such as a heating furnace can be suppressed, even while improving productivity.
(FR)
L'invention concerne un dispositif d'inversion de contenant de poudre pour un four de chauffage, avec lequel il est possible de récupérer la poudre traitée à partir d'un contenant de poudre à haute température. Lorsqu'une paire d'arbres d'inversion (90), (92) est inversée au moyen d'un actionneur d'inversion disposé à l'extérieur d'une chambre d'inversion (62), un contenant de poudre étant maintenu par des dispositifs de serrage (94), (96) fixés à la chambre à l'intérieur de parties d'extrémité des arbres d'inversion (90), (92) est inversé, et la poudre dans le contenant de poudre est retirée. Comme l'actionneur d'inversion et un actionneur de desserrage (130), qui ont une résistance relativement faible à la chaleur, sont disposés à l'extérieur de la chambre d'inversion (62), le contenant de poudre à température relativement élevée peut être inversé pour retirer la poudre de l'intérieur du contenant de poudre. En outre, étant donné qu'il n'est pas nécessaire de réduire la température jusqu'à une température proche de la température ambiante dans une moitié arrière du four de chauffage, permettant au four de chauffage d'être raccourci, une augmentation de la taille d'un équipement thermique tel qu'un four de chauffage peut être supprimée, même en améliorant la productivité.
(JA)
高温の粉体容器から処理粉体を回収可能な加熱炉用粉体容器反転装置を提供する。 反転室(62)の外側に設けられた反転アクチュエータにより一対の反転軸(90)、(92)が反転させられると、反転軸(90)、(92)の室内側端部に固定されたクランプ装置(94)、(96)により把持された粉体容器が反転させられて、粉体容器内の粉体が取り出される。比較的熱に弱い反転アクチュエータおよびアンクランプアクチュエータ(130)は反転室(62)の外側に設けられているので、比較的高温の粉体容器を反転させて粉体容器内の粉体を取り出すことができる。また、加熱炉の後半部分において常温付近まで温度下降させる必要がなくなって加熱炉を短縮することができるので、生産性を高めようとしても、加熱炉などの熱設備が大型化することが抑制される。
