Description

Technical Field

[0001] This utility model relates to the field of zinc powder feeding technology, specifically a zinc powder feeding device for an electric furnace in zinc smelting. Background Technology

[0002] The smelting of zinc powder involves feeding the raw material into an electric furnace and heating it at high temperature to convert the zinc powder into zinc oxide. Then, the zinc oxide is reduced to produce metallic zinc. The feeding of zinc powder into the electric furnace requires a conveying device to achieve automatic feeding of the furnace.

[0003] Patent CN207158362U discloses a zinc powder furnace feeding structure, including a base and a conveyor. The conveyor is fixedly installed on the base, and a feeding hopper is fixedly installed on the conveyor. A screw shaft is rotatably installed inside the conveyor. By driving the screw shaft, the zinc powder in the feeding hopper is transported to the feeding pipe. A pressure relief mechanism is set in the feeding pipe to prevent the zinc vapor in the furnace from being oxidized. The raw material enters the filter chamber through the feeding pipe. The filter chamber not only filters the zinc powder, but also vibrates, causing the raw material adhering to the inner wall of the filter chamber to vibrate down. Finally, the zinc powder flows into the electric furnace.

[0004] In the above scheme, zinc powder is conveyed by rotating the screw shaft. Since the internal space of the electric furnace is limited and the amount of zinc powder heated at high temperature in the electric furnace at one time is limited, the amount of zinc powder conveyed into the feeding pipe by the screw shaft each time must be a specified amount. The existing technology weighs the amount of zinc powder put into the feeding hopper each time to ensure that the screw shaft conveys the specified amount of zinc powder into the feeding pipe each time. This operation method is not only cumbersome and inefficient, but also requires a high degree of concentration from the workers, which can easily lead to errors by the workers and affect the efficiency of the entire zinc powder smelting process.

[0005] Therefore, a zinc powder feeding device for electric furnaces in zinc smelting is needed to improve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a zinc powder feeding device for an electric furnace in zinc smelting, so as to solve the problems mentioned in the background art.

[0008] A zinc powder feeding device for an electric furnace in zinc smelting includes a material cylinder, a feeding cylinder fixedly provided at the lower end of the material cylinder, and a metering mechanism provided at the lower end of the feeding cylinder. The metering mechanism includes:

[0010] The upper end of the outer shell is fixedly equipped with a second cylinder, and the lower end of the second cylinder is fixedly equipped with a second push plate. The lower end of the outer shell is connected to the feed pipe through a feed cylinder.

[0011] As a preferred embodiment of this utility model, the quantitative rotary drum is provided with several material troughs inside, and the upper and lower material cylinders are arranged alternately, with the upper and lower material cylinders corresponding to the material troughs.

[0012] As a preferred embodiment of this utility model, a push plate is slidably provided inside the feed pipe, and a cylinder is fixedly provided on one side of the feed pipe, with the output end of the cylinder fixed to the push plate.

[0015] As a preferred embodiment of this utility model, the feeding cylinder is provided with a spiral shaft that rotates inside, and the spiral shaft is fixedly connected to the lower end of the rotating shaft.

High degree of automation: By driving the scraper and the quantitative drum to rotate through motor one and motor two respectively, continuous quantitative feeding of zinc powder is achieved, eliminating the need for manual weighing, which greatly improves production efficiency, reduces labor costs, and reduces errors caused by human operation.

[0018] 2. Preventing material from sticking to the wall: The motor drives the scraper to rotate inside the cylinder, effectively preventing zinc powder from sticking to the cylinder wall, ensuring smooth material conveying, and avoiding material waste and poor conveying caused by sticking to the wall.
