本考案は加熱槽内の液体を加熱するヒーターに
故障が生じた時、液体を排出することなくヒータ
ーのみの修理を可能にした槽取付用棒状ヒーター
に関するものである。[Detailed Description of the Invention] The present invention relates to a rod-shaped heater for attaching to a tank, which makes it possible to repair only the heater without draining the liquid when a failure occurs in the heater that heats the liquid in the heating tank.

取つた後、ヒーターケース２，８ごとヒーターを
槽から取り外す必要があつた。 In the conventional heater, as shown in FIG. 11, a nichrome wire 1 processed into a coil shape is inserted into a heat-resistant insulating tube 3 arranged radially inside a heater case 2, and a nichrome wire 1 is inserted between the heater case 2 and the heat-resistant insulating tube 3. Filling with heat-resistant insulating material 4 such as magnesia or alumina, or
As shown in Figure 0, a nichrome wire 7 processed into a coil shape is housed in a honeycomb-shaped hole 5 provided in a heat-resistant glass 6, and a heat-resistant insulating material 9 is filled between the heat-resistant glass 6 and the heater case 8. It is configured. For this reason, the nichrome wires 1 and 7 may be disconnected, and the heater case 2,
If the heater case 8 comes in contact with the heater case 8 and heating becomes impossible, it is impossible to replace only the contents of the heater with the heater cases 2 and 8 placed horizontally. That is, in order to fill the heat-resistant insulating materials 4 and 9, the heater cases 2 and 8 must be positioned vertically, and after draining all the liquid in tanks such as water tanks, oil tanks, and cleaning tanks, It was necessary to remove the heater from the tank.
ニクロム線の熱は、耐熱絶縁材の熱伝導率が良
くないのでヒーターケースの表面とニクロム線と

加わる場合、ヒーターケースの内部に充填された
粉状の絶縁材は移動し易く、振動が強力だと破損
したり、さらにニクロム線がヒーターケースに接
触することが多いという欠点があつた。 Since the heat conductivity of the heat-resistant insulating material is not good, the temperature difference between the surface of the heater case and the nichrome wire becomes large. In order to reduce this, it was necessary to arrange a large number of them radially. In addition, when vibrations such as ultrasonic waves are applied to the liquid in the tank, the powdered insulating material filled inside the heater case is likely to move, and if the vibration is strong, it may be damaged or the nichrome wire may come into contact with the heater case. The downside is that there are a lot of things.
