Problems solved by technology

[0003] The existing zinc powder is prepared by the atomization method, and its production equipment includes a zinc melting furnace, a heat preservation flow pipe, a heat preservation electric furnace and an atomizer. The electric furnace quantitatively controls the flow rate, and flows into the atomizer for atomization to obtain zinc powder. However, in the existing devices, especially at the joints of each device, the zinc liquid tends to flow too slowly, causing solidification and deposition, and long-term blockage of the pipeline. Not smooth

Abstract

The invention provides an electric heat-preservation stove for zinc powder production. The electric heat-preservation stove comprises a stove body with a cavity, a heating coil wound around the stove body and an iron core arranged outside the heating coil are arranged at the periphery of the lower half portion of the stove body, inflow holes are formed in the side wall of the upper half portion of the stove body horizontally, outflow holes are formed in the bottom of the stove body vertically, a flow adjusting device is arranged above the outflow holes, the flow adjusting device is arranged in the stove body, the flow adjusting device and the stove body are in threaded connection with an adjusting rod, and the diameters of the inflow holes are gradually increased from outside to inside of the stove body. The electric heat-preservation stove for zinc powder production has the advantages that liquid zinc is not solidified, and flows smoothly.

Description

technical field [0001] The invention relates to a zinc powder processing and manufacturing device, in particular to a heat-retaining electric furnace used for zinc powder production. Background technique [0002] Zinc powder is dark gray powder and can be used as a pigment with strong hiding power. It has good anti-rust and atmospheric corrosion resistance. It is often used to make antirust paint, strong reducing agent, etc. [0003] The existing zinc powder is prepared by the atomization method, and its production equipment includes a zinc melting furnace, a heat preservation flow pipe, a heat preservation electric furnace and an atomizer. The electric furnace quantitatively controls the flow rate, and flows into the atomizer for atomization to obtain zinc powder. However, in the existing devices, especially at the joints of each device, the zinc liquid tends to flow too slowly, causing solidification and deposition, and long-term blockage of the pipeline. Not smooth. ...
