Description

Technical Field

[0001] This invention relates to a zinc powder preparation equipment and method, specifically to a billet smelting system for preparing spherical zinc powder and its processing method. Background Technology

[0002] Zinc powder particles are produced by atomizing molten zinc liquid or electrolyzing zinc salt solutions. The particle size is controllable and the activity is high. As a negative electrode material for alkaline batteries, it generates electricity by reacting with the electrolyte. It is also used in zinc-rich anti-corrosion coatings to delay metal corrosion using the cathodic protection principle. In the chemical industry, it acts as a reducing agent or catalyst, participating in organic synthesis and rubber vulcanization. In addition, ultrafine zinc powder can also be used to manufacture fireworks, medical astringents, and sunscreen cosmetics. Its high specific surface area makes it highly efficient in reactions, while micron-sized particles balance reactivity and storage stability, making it widely used in energy, protection, and materials science fields.

[0003] In existing technology: 202110849148.2 A smelting system is provided, which can effectively reduce the acid loss rate of smelting slag, thus facilitating the direct resource recycling of smelting slag. This application provides a smelting system comprising: a first smelting furnace, a second smelting furnace, an auxiliary material storage bin, a feeding unit, and a conveying unit. The smelting chamber of the second smelting furnace is connected to the slag outlet of the first smelting furnace. The feeding unit has a hopper connected to the smelting chamber of the second smelting furnace. The conveying unit is located between the outlet end of the auxiliary material storage bin and the inlet end of the hopper, used to add materials from the auxiliary material storage bin into the hopper. The second smelting furnace is located at the slag outlet of the first smelting furnace for remelting the hot slag generated from the smelting in the first smelting furnace. The feeding unit, in conjunction with the auxiliary material storage bin, adds auxiliary materials from the auxiliary material storage bin to the second smelting furnace to adjust the slag shape of the hot slag, effectively reducing the acid loss rate of the smelting slag generated after remelting in the second smelting furnace, thereby facilitating the direct resource recycling of the smelting slag.

[0004] Although existing smelting systems can adjust the slag shape of hot smelting slag to effectively reduce the acid loss rate of smelting slag produced after remelting in a second smelting furnace, they also cannot continuously and efficiently produce zinc powder. The zinc powder production process cannot be carried out in multiple continuous smelting systems to form a large scale. Summary of the Invention

Zinc powder collection hopper is used in zinc powder collection. The zinc powder collection hopper is a conical collection hopper for collecting zinc powder granules.

[0010] (3) Packaging and storage equipment for zinc powder granules

[0011] Zinc powder particles are collected using a conical collecting hopper. A collecting trolley is set below the conical collecting hopper, and the collecting trolley has a storage space. The core material particles are placed into the storage space on the collecting trolley. The collecting trolley can be used as a storage device for zinc powder particles, making storage and transportation more efficient.

[0012] The equipment used in raw material crushing includes a crusher and a batching system. The crusher has a feed port through which zinc powder enters the crusher. The crusher has a stratified crushing zone, which is divided into a coarse crushing zone and a fine crushing zone.

[0015] The zinc powder granule roasting furnace performs preliminary roasting. The furnace contains roasting components and a roasting zone. A heating channel is located on one side of the roasting zone. Zinc powder granules are placed in the heating channel, which contains a burner nozzle that emits flames to heat the channel. A high-efficiency combustion structure is installed on the heating channel, containing a combustion pipe. Heating oil is injected into the combustion pipe, which has a heating area plate. A combustion tube is installed on the heating area plate, and the combustion tube and combustion pipe are interconnected. A bottom fire-gathering section, which is an arc-shaped fire-gathering plate, is located on the bottom surface of the heating channel.

[0016] The reduction furnace contains zinc powder particles and is equipped with multiple layers of partitions. Each partition has a support groove for holding the zinc powder particles. A heating zone is located at the bottom of the furnace, and an assembly isolation mesh with multiple mesh openings is installed within this zone. Heating resistance wires are positioned between the mesh openings. A ventilation duct is located at the bottom of the heating zone, and a fan is installed on one side of the ventilation duct. The fan delivers air into the channel duct at the bottom of the heating zone, and the air input from the fan passes through the heating resistance wires to form hot air. This hot air reduces the zinc powder particles within the furnace. A preheating pipe is also provided in the heating zone, which redirects heat back into the ventilation duct.

An adsorption die-casting block is embedded in the air flotation particle module, and the adsorption die-casting block is a microbial enzyme die-casting block.

[0019] The zinc powder particles treated in the electrolytic cell are then subjected to secondary drying in a drying equipment. A high-efficiency drying chamber is used, containing a drying platform on which the zinc powder particles are placed. A drying channel runs along the inner wall of the drying chamber, through which hot air flows. The inner wall of the drying channel is coated with a heat-absorbing filling material, further enhancing the thermal efficiency of the heat. The heated zinc powder particles are then collected using a collection device.

[0020] A collection trolley is set below the conical collection hopper. The collection trolley has a storage space. The core material particles are placed into the storage space on the collection trolley. A test camera is set on the collection trolley.

[0021] The operation method of a billet smelting system for preparing spherical zinc powder is as follows:

[0022] The first step involves crushing the raw materials using a crusher and a batching system. The crusher is used to crush zinc concentrate or zinc-containing raw materials to a suitable particle size to ensure subsequent smelting efficiency. Then, the batching system is used to batch the materials, mixing mineral powder, coke, and slagging agent in a specific ratio. The slagging agent allows the crushed zinc powder to agglomerate and form granules, thus obtaining zinc powder particles.

[0023] The second step involves preliminary smelting operations. The smelting system equipment also includes: a roasting furnace: the zinc powder particles are initially roasted in the roasting furnace, and then the roasted zinc powder particles undergo reduction treatment. The zinc powder particles can be placed in the reduction furnace for processing. The reduction furnace: by adding a reducing agent, the air input by the blower passes through the heating resistance wire to form hot air, which reduces the zinc powder particles in the reduction furnace. Then, electrolysis is carried out. An electrolytic cell: used for electrolytic refining, removing impurities from the zinc powder particles through electrochemical action. The zinc powder particles after electrolysis undergo secondary drying using a drying box. After drying, the zinc powder particles are collected again using a collection device. The collection device uses a zinc powder collection hopper: a conical collection hopper is set at the bottom of the condensation chamber to collect the cooled zinc powder and remove impurities through a screen.

[0024] The third step is packaging and storage. Zinc powder particles are collected using a conical collection hopper. A collection trolley is set up below the conical collection hopper, and the collection trolley has a storage space. The core material particles are placed into the storage space on the collection trolley. The collection trolley is equipped with a test camera that captures images of the surrounding environment. The collection trolley is equipped with a position chip, which works with the operation center to guide the collection trolley to the predetermined location.

[0025] Compared with existing technologies, (1) the coarse crushing zone uses a hydraulic cylinder to drive the laminate plate to apply high pressure to the raw material. The cooperation between the laminate teeth and the coarse crushing plate quickly achieves the initial crushing of large materials, reducing the subsequent fine crushing burden. The fine crushing zone is driven by a drive motor to rotate the fine crushing rod at high speed. The fine crushing teeth refine the material to the target particle size through shearing and collision. The two-layer structure has a clear division of labor, which significantly improves the crushing efficiency. The hydraulic dynamic discharge head monitors the material height in the collection tank in real time through the induction contact. When the zinc powder accumulates to the set position, the inductive valve is automatically triggered to control the opening and closing of the gate for discharge, avoiding the material blockage or over-crushing problems caused by the traditional fixed discharge port.

[0026] (2) A bottom fire-gathering plate is provided on the bottom surface of the heating channel. The bottom fire-gathering plate has a certain arc shape, which can make the flame reflection effect better, reduce the direct loss of heat to the surrounding environment, and allow more heat to be concentrated on the heating channel itself, thereby enhancing the heat transfer to the roasting area. A high-efficiency combustion structure is provided on the heating channel, and a heating area plate is provided on the combustion pipe. The heating area plate is provided with combustion tubes to increase the contact area and enhance the heat conduction effect.

[0027] (3) The combination of multi-layer partitions and shelving tanks allows zinc powder particles to be placed in layers, avoiding uneven heating caused by accumulation. At the same time, the arc-shaped guide channel and gradient opening design form a spiral airflow, enhancing the contact efficiency between hot air and materials, and ensuring a uniform and sufficient reduction reaction. The assembly isolation net adopts a corrugated metal mesh structure, which not only evenly disperses the airflow to ensure stable operation of the heating resistance wire, but also physically isolates the materials to prevent short circuit risks. Combined with the resistance wire layout with zoned temperature control, it achieves precise temperature control and extends the equipment life. The waste heat of the exhaust gas is used to preheat the fresh air, reducing energy consumption. Attached Figure Description

The material flow dynamically adjusts the discharge rhythm. The layered crushing and dynamic discharge modules are integrated into one integrated equipment. The hydraulic system and the drive motor work together. Combined with the precise control of the inductive valve, the entire process from feeding, crushing to discharge is automated.

[0045] The batching system 2 is a zinc powder batching assembly device, which is a zinc powder storage silo. The top of the zinc powder storage silo is equipped with a raw material inlet 21.

The magnetic suction roller adsorbs iron filings and residues in the zinc powder billet. A slagging agent is poured into the zinc powder billet after it has been magnetically attracted, and the slagging agent is used to form zinc powder particles from the zinc powder billet.

[0046] The zinc powder storage silo delivers initial zinc powder, mineral powder, and coke in separate zones. Utilizing the airflow disturbance from the hollow blower rod and nozzles, it achieves thorough mixing and dispersion of the billet, providing a homogenized raw material base for subsequent smelting. The magnetic roller 24, driven by a built-in magnetic core rod and motor, automatically adsorbs magnetic impurities such as iron filings from the zinc powder billet, improving impurity removal efficiency, reducing material loss, and ensuring the purity of the zinc powder particles. By quantitatively adding a slagging agent to the impurity-removed billet, a chemical reaction promotes particle bonding and forming, effectively controlling the particle size distribution and structural stability of the zinc powder particles. Simultaneously, it shortens natural cooling or sintering time, reducing energy consumption and production costs.
