It can quickly cool the aluminum slag and effectively utilize the residual heat of the aluminum slag, reducing energy consumption.

Description

Technical Field

[0001] This utility model relates to the technical field of aluminum smelting supporting components, and in particular to an aluminum smelting slag recycling device. Background Technology

[0002] Aluminum smelting refers to the process of extracting pure aluminum from bauxite, including steps such as crushing, dissolving, purifying and electrolyzing the ore. Aluminum casting involves pouring the molten aluminum into a mold, and after cooling and solidification, obtaining aluminum products of the desired shape. Aluminum smelting and casting are common production processes for aluminum products. During the smelting of aluminum ingots, recycling equipment is needed to regularly clean the aluminum slag on the surface of the molten aluminum to ensure the quality of the molten aluminum.

[0003] The existing aluminum smelting slag recycling process has the following drawbacks: When cleaning aluminum slag during aluminum smelting, the receiving box needs to be moved to the furnace feeding end, and then the aluminum slag on the surface of the molten aluminum is scraped out into the receiving box by a loader, and then transferred to the recycling equipment. The receiving box generally adopts a common metal box structure, and the cooling rate of the aluminum slag after being scraped into it is slow. At the same time, the scraped aluminum slag has a high temperature, which leads to a lot of heat energy waste during the static collection process in the receiving box. Therefore, we propose an aluminum smelting slag recycling device. Utility Model Content

[0004] The main purpose of this utility model is to provide a smelting aluminum slag recycling device. By improving the structure of the receiving box and the feeding and discharging end of the smelting furnace, the receiving box can cool the internal aluminum slag and heat the water during the receiving process, thereby improving the utilization of heat energy and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A smelting aluminum slag recycling device includes a smelting furnace body and a recycling mechanism. The recycling mechanism is provided at the inlet and outlet ends of the smelting furnace body. The recycling mechanism includes a receiving box, a coil, an inlet pipe, a discharge pipe, a water inlet pipe, and a drain pipe. The receiving box is located at the open end of the smelting furnace body, and the coil is embedded in the bottom of the receiving box. The water inlet end of the coil is provided with an inlet pipe, and the drain end of the coil is provided with a discharge pipe. The water inlet pipe and the drain pipe are respectively arranged on both sides of the outer periphery of the smelting furnace body. The end of the inlet pipe is connected to the end of the water inlet pipe, and the end of the discharge pipe is connected to the end of the drain pipe.

[0007] Furthermore, a limiting seat is welded to the bottom side of the smelting furnace body. The limiting seat is located on the side of the smelting furnace body's inlet and outlet ends, and the receiving box is inserted into the limiting seat. An inclined plate is welded between the ends of the limiting seat. A limiting seat structure is fixed at the inlet end of the smelting furnace body. The limiting seat structure is specially designed according to the installation positions of the water inlet pipe, the drain pipe, and the receiving box. An inclined plate is provided on the side of the limiting seat. When the forklift pushes the receiving box close to the smelting furnace body, the inclined plate facilitates the insertion of the receiving box into the limiting seat. The limiting seat can limit the horizontal movement of the receiving box, preventing it from shifting laterally. At the same time, it ensures that after the receiving box is moved into place, the ends of the water inlet pipe and the drain pipe can be accurately inserted into the conical groove, ensuring the connection between the pipes.

[0008] Furthermore, the bottom side of the receiving box is symmetrically provided with conical grooves, and the ends of the inlet pipe and the outlet pipe are connected to the ends of the conical grooves. The conical groove structure facilitates the insertion of the ends of the water inlet pipe and the water outlet pipe into the receiving box to connect with the ends of the inlet pipe and the outlet pipe.

[0009] Furthermore, conical pistons are bonded to the outer periphery of both the inlet and outlet pipes. The conical pistons are inserted into the conical groove and fit against the inner wall of the conical groove. Valves are installed inside both the inlet and outlet pipes. When the receiving box is moved into place, the conical pistons are inserted into the conical groove and fit against the inner wall of the conical groove, maintaining the sealing of the pipe connection. The valve structure is used to control the opening and closing of the inlet and outlet pipes.

[0010] Furthermore, a guide plate is welded to the top side of the receiving box, and the end of the guide plate is attached to the surface of the smelting furnace body. A bracket is welded to the bottom of the receiving box, and a slot is opened inside the bracket. After the receiving box is moved into place, the guide plate is attached to the smelting furnace body. When aluminum slag is scraped out, it will be discharged into the receiving box along the guide plate. Through the bracket and the slot inside, it is convenient for the forklift fork arm to be inserted and thus move the position of the receiving box.

[0011] Furthermore, the receiving box is inserted between the limiting seats and the sides of the receiving box are all attached to the surface of the limiting seats; the position of the receiving box is restricted by the limiting seat structure to ensure that it can be connected to the water inlet pipe and the drain pipe.

[0012] Compared with the prior art, this utility model has the following beneficial effects: Water inlet pipes and drain pipes are respectively arranged at the bottom of both sides of the feeding end of the smelting furnace body. The water inlet pipes are connected to the external cold water supply pipeline, and the drain pipes are connected to the external hot water centralized recovery pipeline. Both the water inlet pipes and drain pipes are normally closed. A coil structure is built into the bottom of the receiving box. When using the receiving box to collect aluminum slag, it is moved to the feeding end of the smelting furnace body. After being moved into place, the ends of the water inlet pipes and drain pipes are respectively inserted into the conical groove to connect with the supply pipe and discharge pipe. At this time, the water inlet pipe valve is opened, and water is supplied to the inside of the coil. When the aluminum slag is loaded into the receiving box, the low temperature of the water rapidly cools the aluminum slag, causing it to solidify, facilitating subsequent recycling and preventing the aluminum slag from adhering to the inner wall of the receiving box. Simultaneously, the aluminum slag... The waste heat can heat the water inside the coil. After the water is heated, the drain valve is opened to release the hot water for centralized use, expanding the functionality of the receiving box. It can quickly cool aluminum slag and effectively utilize the waste heat of aluminum slag, reducing energy consumption. A limiting seat structure is fixed at the feeding end of the smelting furnace. The limiting seat structure is specially designed according to the installation position of the water inlet pipe, drain pipe and receiving box. An inclined plate is provided on the side of the limiting seat. When the forklift pushes the receiving box close to the smelting furnace, the inclined plate facilitates the insertion of the receiving box into the limiting seat. The limiting seat can limit the horizontal movement of the receiving box, so that the receiving box cannot be offset laterally. At the same time, it ensures that after it moves into place, the ends of the water inlet pipe and drain pipe can be accurately inserted into the conical groove, ensuring the connection between the pipes.

The end of the inlet pipe 203 is connected to the end of the water inlet pipe 206, and the end of the outlet pipe 204 is connected to the end of the drain pipe 207.

[0020] The furnace body 1 has a limiting seat 3 welded to its bottom side. The limiting seat 3 is located on the side of the furnace body 1 at the inlet and outlet end, and the receiving box 201 is inserted into the limiting seat 3.

An inclined plate 301 is provided on the side of the limiting seat 3. When the forklift pushes the receiving box 201 close to the furnace body 1, the inclined plate 301 facilitates the insertion of the receiving box 201 into the limiting seat 3. The limiting seat 3 can limit the receiving box 201 during horizontal movement, so that the receiving box 201 cannot be laterally offset. At the same time, it ensures that after it moves into place, the ends of the water inlet pipe 206 and the drain pipe 207 can be accurately inserted into the conical groove 205 to ensure the connection between the pipes.

[0021] The receiving box 201 has symmetrically arranged conical grooves 205 on its bottom side. The ends of the inlet pipe 203 and the outlet pipe 204 are connected to the ends of the conical grooves 205. Conical pistons 208 are glued to the outer periphery of the ends of the inlet pipe 206 and the outlet pipe 207. The conical pistons 208 are inserted into the conical grooves 205 and fit against the inner wall of the conical grooves 205. Valves 209 are installed inside the inlet pipes 206 and the outlet pipes 207. The structure of the conical grooves 205 facilitates the insertion of the ends of the inlet pipes 206 and the outlet pipes 207 into the receiving box 201 to connect with the ends of the inlet pipes 203 and the outlet pipes 204. When the receiving box 201 is moved into place, the conical pistons 208 are inserted into the conical grooves 205 and fit against the inner wall of the conical grooves 205, maintaining the sealing of the pipe connections. The valves 209 are used to control the opening and closing of the inlet pipes 206 and the outlet pipes 207.

After it is moved into place, the ends of the water inlet pipe 206 and the drain pipe 207 are respectively inserted into the conical groove 205 to connect with the feed pipe 203 and the discharge pipe 204. At this time, the valve 209 of the water inlet pipe 206 is opened, and water is delivered into the coil 202. When the aluminum slag is loaded into the receiving box 201, the aluminum slag is rapidly cooled by the low temperature of the water to solidify it, making it easier for subsequent recycling and preventing the aluminum slag from adhering to the receiving box 201. The inner wall of the coil 202 is heated by the residual heat from the aluminum slag. Once the water is heated, the drain pipe 207 and valve 209 are opened to release the hot water for centralized use, thus expanding the functionality of the receiving box 201. This allows for rapid cooling of the aluminum slag while effectively utilizing its residual heat and reducing energy consumption.
