  • 2T 5T 10T 15T 20T 25T 50T pot lead cover for lead refining furnace Cover for lead potThe utility model discloses a lead pot cover that is convenient for removing slag from lead liquid, and relates to the technical field of battery production. The utility model includes a lead pot cover and a slag removal device; The lead pot cover includes a cover ring and a cover plate; The upper surface of the cover plate is provided with a radially arranged rectangular groove; The bottom surface of the rectangular groove is provided with a slag removal port; One side of the slag removal port is fixedly connected with a conduit side by side; The slag removal device includes a fixed rod that matches the surface inside the conduit; Two fixing rods are fixedly connected with a handle on the upper and lower sides through a connecting block; A Rectangular cuboid slag leakage box is fixedly connected with the side faces of the lower ends of the two fixed rods through a connecting block. The utility model seals the lead pot by setting a lead pot cover matched with the lead pot, which solves the problem that the lead liquid in the existing lead pot is easy to contact with oxygen to produce lead slag, which affects the product quality; At the same time, the slag removal device can perform the slag removal operation without removing the lead pot cover, providing convenience for the slag removal of lead liquid and effectively ensuring the quality of lead liquid。

  • equipment metal refining for mine and metallurgy scrap lead battery refining furnace Reflection refining furnaceThe present invention discloses a bottom blowing process for alkaline refining of regenerated lead by fire method. After the crude lead liquid is poured into the refining furnace from the melting furnace, argon gas is introduced from the bottom. When the temperature of the lead liquid drops to about 330 ℃, slag is skimmed, and the lead copper content is reduced to about 0.1% by melting and removing copper. After skimming, sulfur powder is sprayed into the bottom of the refining furnace to further remove copper. The temperature is raised to 450-480 ℃, and the reaction is carried out for 30-60 minutes. The sulfide slag is removed to complete the copper removal process; When the lead liquid temperature is about 450 ℃, powdered Sodium nitrate and sodium hydroxide are blown from the bottom of the refining furnace. After reaction for 30min, NaCl powder is blown from the bottom of the refining furnace with argon gas to complete the arsenic, antimony and tin removal process. The loss of said bottom blowing process method, refining agent and/or alloy is greatly reduced; There is only inert gas with low solid solubility in the lead liquid, which is not easily oxidized by the lead liquid and lead ingot. There is no lead slag inside the lead liquid and lead ingot. When using recycled lead, there is less lead slag and the slag yield is low; During the refining process, the surface of the lead liquid is always protected by argon gas, which can be used for high-temperature Ag removal operations. The regenerated lead contains low Ag content; The argon gas blown into the bottom will float together with small bismuth compound particles, resulting in low bismuth content in lead ingots

  • 3T 5T 10T 15T smelting rotary furnace for scrap lead battery recyclingRotary smelting furnace A rotary furnace is a type of blast furnace, whose body is an inclined cylindrical container that can rotate. The principle of rotary furnace is to use the effect of high temperature and high-speed Redox to mix ore and coke together, rapidly heat and melt in the furnace, and separate metal and waste slag.The internal parts of the rotary furnace are divided into different areas, with the top layer being the combustion zone, where coke and oxygen react to produce high-temperature and high-pressure gas flow. The gas flows downwards and enters the reduction zone. The ore and coke undergo a reduction reaction in the reduction zone, and the metal is reduced out. The metal flows downwards along the furnace barrel and finally reaches the slag area, where it is separated from the waste slag.The rotary furnace has the advantages of high production capacity and high melting efficiency, and can melt various metal materials such as iron, steel, and alloys. In the steel industry, rotary furnaces have become one of the main steelmaking equipment, widely used in fields such as steelmaking, ironmaking, and scrap recovery. Lead scraps, Lead grid, Lead acid battery scrap, adaptable to different raw materials.The Lead melting rotary furnace consists of a rotary host, a fire-resistant furnace lining, a combustion system, a hydraulic system, a Ring gear transmission system and a flue system. Both charging and discharging pass through the furnace mouth installed with a furnace door. During charging and discharging, the furnace door installed with a burner can be opened. Auxiliary machines are equipped with supporting automatic feeding machine, automatic slag (soup) bag and slag raking machine, and automatic ingot casting and stacking machine. Through these supporting equipment, the automatic operation of the whole process can be realized. Details include:- Refractory Material of Chrome-Magnesium basis- air-fuel burner or Oxy-fuel burner or Heavy oil burner- Feeding door opening through local control panel and through remote control- Door operation system with hydraulic unit;- Rotation system 0 - 1 rpm with variable speed driver (by VFD)
