Abstract

The utility model relates to a heater used in vacuum furnaces, in particular to a vacuum furnace heater comprising a high-temperature confluence disc (1), heating rods (2) and a low-temperature confluence disc (3). The vacuum furnace heater is characterized by further comprising a copper electrode (4), one ends of a plurality of heating rods are inserted into the high-temperature confluence disc (1), the other ends penetrate the low-temperature confluence disc (3) to fix on the copper electrode (4), and the copper electrode (4) and the low-temperature confluence disc (3) are both composed of two separated semicircle disc components. Compared with a traditional heater where tops of the heating rods are curved, the vacuum furnace heater has the advantages that problems that the heater deforms and damages since the heating rods are heated for a long time and radiated unevenly can be avoided effectively, and service life of the heater can be prolonged effectively.

Description

A kind of vacuum drying oven heater

Technical field

The utility model relates to the electro-heat equipment of using in a kind of vacuum drying oven, specifically a kind of vacuum drying oven heater.

Background technology

Heater is the heating element heater of vacuum drying oven, one of vital parts of vacuum drying oven, due to needs heating power, therefore heater generally selects dystectic materials such as tungsten, molybdenum to make, make it in long-term use procedure, keep good working order, the heater of vacuum drying oven is centered around around the outer wall of crucible conventionally, for it provides heat, for latticed vacuum drying oven heater, its many heating bars need to have identical length, so that the heat producing on every heating bar is roughly the same, thereby avoid making because heating pole length is different the uneven heater that causes of heat producing on each heating bar to be out of shape, so, certain bending section with height fall is arranged at the top of the heating bar of latticed heater conventionally, but, still there is larger problem in this setup, because the grid heater of this whole shape is prone to bulk deformation, easy secundly particularly, cause stove to damage, cannot normally use.

Utility model content

In order to solve the problems of the technologies described above, the utility model provides a kind of durable and on-deformable vacuum drying oven heater.

The utility model is to solve the problems of the technologies described above adopted technical scheme to be: a kind of vacuum drying oven heater, comprise high temperature conflux disk, heating bar and copper electrode, also be provided with low temperature conflux disk, insert in high temperature conflux disk many isometric heating bar one end, the other end is fixed on copper electrode through after low temperature conflux disk, and described copper electrode and low temperature conflux disk are two semicircle plate-likes of separating.

Heating bar one end is inserted in high temperature conflux disk, the other end is through on fixed copper electrode after low temperature conflux disk, low temperature conflux disk mainly plays a part to collect, fixing heating bar, copper electrode and low temperature cylinder manifold are two semicircle plate-likes of separating, two low temperature conflux disks form a current loop with heating bar, high temperature conflux disk, to heater after energising on low temperature conflux disk, can start working.

Setting as a kind of optimum, insert in high temperature conflux disk described many heating bar one end, after other end bending, surround cylindric, and through on fixed copper electrode after low temperature conflux disk, this setup can be in the situation that do not change the big or small of high temperature conflux disk, and the volume of the cylinder that suitable increase heating bar surrounds, can adapt to the crucible of different volumes with this, heating bar inserts low temperature conflux disk and is fixed by jackscrew, is held out against on low temperature conflux disk.

Beneficial effect: a kind of vacuum drying oven heater of the utility model adopts many heating bar one end to insert in high temperature conflux disk, the other end is fixed on the set-up mode on copper electrode through after low temperature conflux disk, be arranged to the heater of curved shape compares with traditional heating masthead end, the utility model can effectively avoid generating heat bar be heated for a long time after the uneven heater distortion causing of heat radiation, the problem of damaging, can effectively extend service life of heater.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described: a kind of vacuum drying oven heater as shown in the figure, comprise high temperature conflux disk 1, heating bar 2, low temperature conflux disk 3 and copper electrode 4, as Fig. 1, shown in Fig. 2, insert in high temperature conflux disk 1 many isometric heating bar 2 one end, the other end is fixed on copper electrode 4 through after low temperature conflux disk 3, it is two semicircle plate-likes of separating that low temperature conflux disk 3 and copper electrode 4 are, copper electrode 4 is arranged on the top of low temperature collection board 3, heating bar 2 is held out against by jackscrew 5 in the part of low temperature conflux disk 3, after being inserted on low temperature conflux disk 3, heating bar is fixed on copper electrode 4.

Heating bar 2 in the utility model generally selects tungsten to make, also can be with exotic materials such as molybdenums, after heating bar 2 one end are inserted in high temperature conflux disk 1, the other end can surround cylindric after bending, afterwards through low temperature collection board 3, be fixed on copper electrode 4, this mode that makes its shorter bending section insert high temperature conflux disk 1 can under the situation that does not change high temperature conflux disk 1 size, increase that heating bar surrounds tin area, make the heater itself can the larger crucible of receiving volume.

The utility model is not narrated part for prior art.
