Problems solved by technology

[0003] In order to improve the electric heating efficiency of the intermediate frequency furnace, the axial flow pipe is installed in the intermediate frequency furnace to speed up the flow of air in the furnace body. At present, most of the devices used to speed up the air flow in the axial flow duct are fans, but the fan is limited by its own structure. After all, the air flow rate is limited, and the heating efficiency of the intermediate frequency furnace needs to be further improved

Abstract

The invention discloses an intermediate frequency furnace axial flow pipeline air mixing pressurizing nozzle. A first pressurizing cylinder and a second pressurizing cylinder are connected, and a one-way valve is arranged on the first pressurizing cylinder; a high-pressure air inlet is formed in the one-way valve, and a first control valve rod and a second control valve rod are arranged on the second pressurizing cylinder; a telescopic rod is arranged on the second pressurizing cylinder, and an adjusting rotary knob is arranged on the telescopic rod; and the length of the telescopic rod can beadjusted by rotating the adjusting rotary knob, and the tail end of the telescopic rod is provided with a high-pressure nozzle. According to the intermediate frequency furnace axial flow pipeline airmixing pressurizing nozzle, the two pressurizing cylinders are arranged on a body and are each of a one-way communicating structure, external air is pressurized in the pressurizing cylinders to forma high-pressure air flow to be sprayed out of the nozzle, the sprayed high-pressure air forms a high-speed fluid in an axial flow pipeline, and thus the heating efficiency of an intermediate frequencyfurnace is effectively improved.

Description

technical field [0001] The invention relates to an air mixing pressurized nozzle of an axial flow pipeline of an intermediate frequency furnace. Background technique [0002] The working frequency of the medium frequency induction furnace is between 50-10 Hz, and it is widely used in the smelting of non-ferrous metals and ferrous metals. Compared with other casting equipment, the medium frequency induction furnace has the advantages of high thermal efficiency, short melting time, less burning loss of alloy elements, wide range of melting materials, less environmental pollution, and precise control of the temperature and composition of molten metal. [0003] In order to improve the electric heating efficiency of the intermediate frequency furnace, the axial flow pipe is installed in the intermediate frequency furnace to speed up the flow of air in the furnace body. At present, most of the devices used to speed up the air flow in the axial flow duct are fans, but the fan is ...
