Abstract
The invention discloses vacuum heating equipment, which solves the problems that the conventional vacuum heating equipment has an unreasonable structure and a heating molybdenum belt is required to be replaced frequently. Two magnetic sleeves (6) and an electrode (8) are respectively arranged on a furnace outer sleeve (7); one end of a pin (11) is fixedly arranged on a furnace inner cavity in the furnace outer sleeve (7) by a nut (12); the other end of the pin (11) is connected together with a magnetic seat (14) by a molybdenum wire (13); one end of the heating molybdenum belt (10) is fixedly connected with the electrode (8), and the other end of the heating molybdenum belt (10) is fixedly connected with another electrode; the heating molybdenum belt (10) is distributed in the furnace inner cavity in the furnace outer sleeve (7) along a furnace in an arc mode; and two parallel pressing marks (5) are formed on the heating molybdenum belt (10). In the vacuum heating equipment, the heating molybdenum belt is not deformed, and production cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of vacuum equipment, particularly a kind of vacuum equipment of the heating molybdenum band at hot operation more than 1000 ℃, heating molybdenum band places the circular heating clamber of high-temperature vacuum equipment.
Background technology
In heating molybdenum band vacuum equipment, the thickness of heating molybdenum band is generally 0.8 millimeter to 1.2 millimeters, and width is generally 50 millimeters to 80 millimeters, and crack conditions can appear in heating molybdenum band majority in use for some time.The heating molybdenum band vacuum equipment that uses mainly contains following shortcoming at present: heating molybdenum band strength is not enough; Heating molybdenum band supported hole is a circular hole, and making band prolong circumferencial direction does not have flexible surplus, causes heating tape distortion and fracture.Heating molybdenum band and electrode switching place contact area are little, and the bolt expanded by heating is fixing not tight, the arcing phenomenon can occur, even can make the band scorification because of overcurrent.The heating molybdenum band of this kind structure can be out of shape seriously after using a period of time, needs often to change the equipment cost height.
Summary of the invention
The invention provides a kind of vacuum heating apparatus and solved the problem that existing vacuum heating apparatus unreasonable structure needs often to change heating molybdenum band.
The present invention overcomes the above problems by following scheme:
A kind of vacuum heating apparatus, comprise the flue overcoat, outside flue, put and be respectively arranged with two magnetosheaths, be provided with electrode in each magnetosheath respectively, flue inner chamber in the flue overcoat is provided with pin, one end of pin is fixedly installed on the flue inner chamber in the flue overcoat by nut, the other end and the magnetic support of pin link together by molybdenum filament, one end of heating molybdenum band is fixedlyed connected with electrode, the other end of heating molybdenum band is fixedlyed connected with another electrode, heating molybdenum band is to distribute along the flue arc in the flue inner chamber in the flue overcoat, heating molybdenum band is provided with parallel twice impression, band at heating molybdenum band is provided with strip hole on one's body, and trip bolt passes this strip hole successively and the rhombus sheet is fixedly installed on the heating tape on the magnetic support.
The end and the electrode of heating molybdenum band link together by equally distributed 9 hold-down screws, end at heating molybdenum band also is provided with the end strip hole, and the end trip bolt is fixed together by end and the end rhombus sheet that the end strip hole will heat the molybdenum band.
The present invention makes heating molybdenum tape base, and this is indeformable, and maintenance frequency reduces, and has reduced production cost greatly.

Specific embodiment
A kind of vacuum heating apparatus, comprise flue overcoat 7, on flue overcoat 7, be respectively arranged with two magnetosheaths 6, be provided with electrode 8 respectively in each magnetosheath 6, flue inner chamber in the flue overcoat 7 is provided with pin 11, one end of pin 11 is fixedly installed on the flue inner chamber in the flue overcoat 7 by nut 12, the other end of pin 11 and magnetic support 14 link together by molybdenum filament 13, one end of heating molybdenum band 10 is fixedlyed connected with electrode 8, the other end of heating molybdenum band 10 is fixedlyed connected with another electrode, heating molybdenum band 10 is along the distribution of flue arc in the flue inner chamber flue overcoat 7 in, heating molybdenum band 10 is provided with parallel twice impression 5, band at heating molybdenum band 10 is provided with strip hole 3 on one's body, and trip bolt passes this strip hole 3 successively and rhombus sheet 4 is fixedly installed on heating tape 10 on the magnetic support 14.
The end and the electrode 8 of heating molybdenum band 10 link together by equally distributed 9 hold-down screws, end at heating molybdenum band 10 also is provided with end strip hole 2, and the end trip bolt is fixed together by end and the end rhombus sheet that end strip hole 2 will heat molybdenum band 10.
Have strip hole 3 on the heating molybdenum band 10, screw will heat molybdenum band 10 by strip hole 3 and link together with porcelain seat 14.When temperature raise, strip hole 3 left enough elongations for heating molybdenum band; Add the rhombus sheet to increase the intensity at fixing heating molybdenum band place for heating molybdenum band; Add impression with the intensity of increase with self for heating molybdenum band, this structure heating molybdenum band is out of shape hardly.
The magnetosheath that is provided with on flue overcoat 7 and the group number of heating tape can require to calculate the back according to equipment and determine.
