Electric radiators, especially for galvanic baths

Di-i innovation concerns one especially for heating of the electrolyte of galvanic baths determined, essentially from an electrical insert and a metallic tubular, protected against the effects of acid Coat existing radiator, which with its ends a? Flange plate penetrated in a liquid-tight manner.

Electric heating elements are already known whose metallic, tubular jacket has a spray or Has coating made of plastic produced by immersion processes, to protect the coat against acid attack. However, the covering is due to its relatively small thickness porous, so that a sure protection: it mantle against acid is not guaranteed. It is also already under consideration been drawn, the 3-sided closed, made of metal or ceramic existing jacket pipe is electrically "hen To provide the radiator with a jacket made of plastic. Here, j ^ do ~ h affects the circumstance :, da :; ier plastic jacket must be provided with a 5m floor, insofar unfavorable than the connection of the floor with the Coat by welding or gluing not only relatively is difficult, but also learn i.-j 3-: hveiü- or glue point is preferably exposed to acid attack.

The heating element with the plastic jacket is bent into the desired shape, for example a U-shape.

Ge'wiCiit ι äi lenoes measure rsuuzi-sr t is, so a reliable protection of the metal jacket against attack by acid is guaranteed.

The innovation is also that between the plastic jacket and the metal jacket of the radiator another metallic tubular jacket is arranged which, together with the jacket immediately surrounding the heating element, makes the flange plate liquid-tight interspersed.

By interposing another metal tubular jacket are any heat nodes that occur degraded + · by dissipating the heat in the axial direction will.

According to another suggestion by the Neujrunn, the Flange plate hohlzyl indr i.sche approaches, in which the plastic jacket with se: η η. ^ Nieri firmly inserted is.

After another suggestion the innovation is at least the coat of artificial peat auiien at the level of the bathroom mirror thickened.

This has the advantage that the plastic jacket in the The area of the bath level where the chemical attack is strongest has the coarsest resistance. The thickening shows: -r the minimum immersion depth of the Radiator on.

The resilience of the plastic sheath in the The area of the bathroom level can also be increased by means of another suggestion of the innovation At the ends of the plastic jacket, a hose made of plastic is drawn, which is expediently up to the Flange plate is sufficient and thus for sealing the bark of the plastic jacket in the cylindrical lugs of the flange plate.

According to a further suggestion of the innovation, the radiator with its sheaths is at the level of the bathroom level constricted, whereby the minimum immersion depth of the radiator can also be easily determined.

In the drawing, the innovation is in two exemplary embodiments on one, in particular for electroplating baths specific electric radiator illustrated. 3s indicates:

The heating element shown in the drawing consists of the heating coil 13 embedded in magnesium oxide, which U-shaped bent and with a metal, tubular Coat ι is provided. The heating coil 13 penetrates a flange plate 5 with its jacket 1 in a liquid-tight manner. The ends of the jacket 1 are closed with the aid of plugs 12 surrounding the heating coil 13. At 11 are Sndbüchsen, with Io connection bolts and with 9 a cover cap is designated.

According to the innovation, the jacket 1 of the radiator with a second metal, tubular, designated with 2 Provided jacket, the inner diameter of which is dimensioned 30,
