Abstract
The utility model discloses a heating element for an electroplating bath. The heating element comprises a snake-shaped pipe, wherein wiring terminals are respectively and fixedly connected with the two ends of the snake-shaped pipe; the wiring terminals and the ends of the snake-shaped pipe are sealed and insulated through silica gel; the snake-shaped pipe is internally provided with a spiral electric heating alloy wire; a gap is reserved between the spiral electric heating alloy wire and the inner wall of the snake-shaped pipe and the gap is filled with magnesium oxide sand in a compact manner; and the two ends of the spiral electric heating alloy wire are respectively and electrically connected with the wiring terminals at the two ends of the snake-shaped pipe. The heating element disclosed by the utility model is simple in structure, high in mechanical strength, high and fast in heating efficiency, safe and reliable, simple and convenient to mount, and long in service life; the snake-shaped pipe helps to enlarge the heating area of a unit length and can bear the temperature of 110 DEG C; and when an acid washing solution is boiling, pressure is generated, thus the heating element has the anti-knock effect, so that the heating element is not easy to damage.
Description
Technical field
The utility model relates to an electric heating element field, specifically a kind of plating tank heating unit.
Background technology
An electric heating element is electric energy conversion to be become the components and parts of heat energy, is widely used on the industry such as electroplating industry, Injection Industry, chemical industry, auxiliary heating and the electrical equipment such as Household electric oven, vertical air conditioner.At electroplating industry, electroplate in tank and be provided with tubular heating element, this straight tube-like heating unit includes straight tube, be provided with electrical heating wire in straight tube, the two ends of straight tube are fixedly connected with respectively the connection terminal that is electrically connected to electrical heating wire, after energising, electric current flows through from electrical heating wire, the electrical heating wire heating, heat is passed to straight tube fast, is used for the heating of Acidwash solution.But the effective heating-surface area of the heating unit of this structure is less, and heats is poor, and can produce pressure to straight tube when the Acidwash solution boiling in the plating tank, constantly impacts straight tube, very easily damages straight tube.
The utility model content
The purpose of this utility model is to provide that a kind of efficiently radiates heat area is large, the plating tank heating unit of anti-vibration, is used for the heating of the Acidwash solution of plating tank.
The technical solution of the utility model is as follows:
A kind of plating tank heating unit, it is characterized in that: include serpentine tube, the two ends of described serpentine tube are fixedly connected with respectively connection terminal, insulate by silica gel sealing between the end of described connection terminal and serpentine tube, be provided with the volution lectrothermal alloy wire in described serpentine tube, have the space between the inwall of described volution lectrothermal alloy wire and serpentine tube, and padding and compacting has magnesium oxide sand, the two ends of volution lectrothermal alloy wire are electrically connected to the connection terminal at serpentine tube two ends respectively.
Described plating tank heating unit is characterized in that: described serpentine tube is stainless steel tube.
Described plating tank heating unit is characterized in that: described connection terminal is fixedly connected on the two ends of serpentine tube by fastening piece.
The beneficial effects of the utility model:
The utility model is simple in structure, and physical strength is high, and thermo-efficiency is high, fast, and is safe and reliable, simple installation, long service life, serpentine tube has increased the heating-surface area of unit length, the temperature that can bear reaches 110 ℃, has pressure also to play anti seismic efficiency when Acidwash solution seethes with excitement, and is not fragile.
