Benefits of technology

The present invention provides a heater for wet extraction tank that consumes low energy, is clean and safe, and efficient for heating. The heater uses a serpentine glass tube material that does not react with the extraction material, ensuring the stability and safety of the appliance and the quality of the separation products. The serpentine tube is designed reasonably to ensure uniform heating and prevent local temperatures from being too high. The heater is easy to install, simple operations, low costs of production and running, low energy consumption, constant temperature, clean and pollution-free, long service life and inexpensive.

Problems solved by technology

In hydrometallurgy, cold winter weather leads to an ambient temperature for the material liquid in extraction tank body is too low, which results in a poor extraction and seriously affects the quality of the separation products.
With auxiliary electric heating the material liquid in extraction tank or keeping thermal insulation for extraction hall, there are problems of high cost, poor insulation and insecurity.

Abstract

A heater and a heating method for a wet extraction tank, said heater comprising a heating tube comprising a spiral glass tube with an air inlet and an air outlet; the air inlet is connected to a steam supply apparatus via a steam tube, and the air outlet is in communication with an apparatus containing micro-steam or hot water; the steam tube has with a pressure regulating valve for adjusting the steam pressure inside the heating tube; the glass tube is fixedly connected to the extraction tank by a wooden material fixed to the tank via a stainless steel bolt; the glass tube is fixed to the wooden material by wrapping and welding a heat and chemical resistant soft plastic sheeting. The heating method comprises maintaining the liquid inside the tank in a constant state of ebullition so that heat is evenly and uniformly distributed throughout the tank.

Description

TECHNICAL FIELD[0001]The present invention relates to a heater and a heating method for heating a clarifying chamber of the tank body of wet extraction tank for extracting, separating, and smelting in winter.BACKGROUND OF THE INVENTION[0002]In hydrometallurgy, cold winter weather leads to an ambient temperature for the material liquid in extraction tank body is too low, which results in a poor extraction and seriously affects the quality of the separation products. With auxiliary electric heating the material liquid in extraction tank or keeping thermal insulation for extraction hall, there are problems of high cost, poor insulation and insecurity.SUMMARY OF THE INVENTION[0003]An object of the present invention is to provide a heater for wet extraction tank, which is with low energy consuming, clean and friendly environment, safe and stable, as well as efficient for heating.[0004]Another object of the present invention is to provide a heating method for wet extraction tank, which is...
