Description

Technical Field

[0001] This utility model relates to the field of furnace devices, and more particularly to a furnace device and metal smelting system with a hammering mechanism at the inlet. Background Technology

[0002] Smelting is a pyrometallurgical process in which metallic materials and other auxiliary materials are melted and tempered in a heating furnace. The materials undergo certain physical and chemical changes within the high-temperature furnace, producing crude metal or metal concentrates and slag. Currently, metal materials are primarily placed manually into a feeding trolley, then transported and poured into the furnace by a transfer trolley. However, during the pouring process, due to factors such as the potentially large pouring angle or the size of the metal material, metal tends to accumulate at the furnace opening. The traditional solution is to manually adjust the position of the metal material at the furnace opening; if accumulation persists, some metal needs to be removed and reshaped. However, this results in workers spending extended periods near the furnace opening, which is detrimental to their health and significantly slows down the furnace's feeding process. Utility Model Content

[0003] The purpose of this utility model is to provide a furnace device with a hammer mechanism at the inlet. A hammer placement cavity for accommodating the pressure hammer is provided on the side of the smelting cavity.

The pressure hammer is pressed down to the opening of the smelting cavity, which can press the accumulated metal into the smelting cavity.

[0025] This solution provides a furnace device with a hammer feeding mechanism at the inlet. A hammer placement cavity for accommodating the pressure hammer is set on the side of the smelting cavity. When it is necessary to push the metal from the opening of the smelting cavity into the interior, the pressure hammer in the hammer placement cavity can be activated.

[0039] like Figure 1-4 A furnace device with a hammering mechanism at the inlet includes: a furnace body 21, a hammering mechanism 23 and a horizontal conveying mechanism 22;

[0040] The furnace body 21 is provided with an upward-opening smelting inner cavity 211, and an upward-opening hammer placement cavity 212 is provided at an adjacent position to the smelting inner cavity 211.

[0041] The hammering mechanism 23 includes: a movable base 231, a winding wheel 232, a lifting rope 233, a pressing hammer 234, and a winding driver 235;

[0042] The take-up reel 232 is rotatably mounted on the movable base 231, the lifting rope 233 is wound around the take-up reel 232, and the lower end of the lifting rope 233 is connected to the pressure hammer 234; the output end of the take-up driver 235 is connected to the take-up reel 232 and is used to drive the take-up reel 232 to rotate, thereby driving the take-up reel 232 to wind or unwind the lifting rope 233;

[0043] The pressure hammer 234 is stored in the hammer placement cavity 212; the output end of the horizontal conveying mechanism 22 is connected to the movable base 231, which is used to drive the movable base 231 to move horizontally and drive the pressure hammer 234 to be conveyed between the hammer placement cavity 212 and the melting inner cavity 211; the pressure hammer 234 falls to the melting inner cavity 211 or the hammer placement cavity 212 along with the hoisting rope 233.

[0044] This solution provides a furnace device with a hammering mechanism at the inlet. A hammer placement cavity 212 for accommodating a pressure hammer 234 is provided on the side of the smelting cavity 211. When it is necessary to push the metal from the opening of the smelting cavity 211 into the interior, the pressure hammer 234 in the hammer placement cavity 212 can be activated. The pressure hammer 234 is pressed down to the opening of the smelting cavity 211, which can press the accumulated metal into the smelting cavity 211. This ensures that the metal is placed into the molten slurry in the furnace body 21 more efficiently and quickly, solving the problems of long-term high-temperature operation and low feeding efficiency that existing furnaces require manual pressing after feeding.

[0045] Specifically, the furnace body 21 is used for melting metal, and metal can be put into it through the opening of its melting cavity 211. The metal falls into the molten metal in the melting cavity 211 and melts. In this design, a hammer placement cavity 212 for a pressure hammer 234 is also placed on the side of the melting cavity 211. Generally, the furnace body 21 is fed by a discharge trolley, which tilts and extends its carriage to directly discharge the metal at an angle. If the tilt angle is too large, the metal can easily accumulate at the opening of the smelting cavity 211. Therefore, this application utilizes a hammer mechanism 23 and a horizontal conveying mechanism 22. The weight hammer 234 located in the smelting cavity 211 has its lifting rope 233 in an unwound state. At this time, a winding driver 235 can be activated. The output end of the winding driver 235 drives the winding wheel 232 to rotate (e.g., clockwise), causing the lifting rope 233 to wind up onto the winding wheel 232. This lifts the weight hammer 234 located in the smelting cavity 211 until the weight hammer 234 is completely detached from the opening of the smelting cavity 211. Then, the horizontal conveying mechanism 22 is activated. The horizontal conveying mechanism 22 drives the moving base 231 to move horizontally, so that the moving base 231 and its pressure hammer 234 move horizontally to a position above the melting cavity 211. Then, the winding driver 235 is started again. The output end of the winding driver 235 drives the winding wheel 232 to rotate (e.g., counterclockwise), which drives the lifting rope 233 to unwind from the winding wheel 232. The lifting rope 233 drives the pressure hammer 234 to fall to the opening of the melting cavity 211. Thus, the weight of the pressure hammer 234 presses the metal accumulated in the opening of the melting cavity 211 into the melting cavity 211, so that the metal melts into the molten metal. In this way, this application realizes the automatic pressing of the accumulated metal into the melting cavity 211, which solves the problem that the existing furnace requires manual pressing after feeding, resulting in long-term high-temperature operation.

[0046] The horizontal conveying mechanism 22 is a known mechanism that drives horizontal movement, such as a combination of a cylinder, hydraulic cylinder, motor and lead screw, or gear and rack combination, or conveyor belt device, as long as it drives the moving base 231 to move horizontally. The winding driver 235 is a known mechanism that drives rotation, such as a motor, or a combination of a motor and reducer.

[0047] Optimally, the opening of the melting cavity 211 is provided with a pre-entry area 2111 and a main entrance area 2112 from top to bottom. The side wall of the pre-entry area 2111 is provided with a stop plate 2113. The main entrance area 2112 is provided with a pressure plate 2114. A feed port 2115 communicating with the interior of the melting cavity 211 is formed between multiple pressure plates 2114. The feed port 2115 is located obliquely below the stop plate 2113.

[0048] The pressure hammer 234 stays on the stop plate 2113. After the hoisting rope 233 is unwound from the take-up reel 232, the horizontal conveying mechanism 22 drives the moving base 231 to move horizontally toward the feed port 2115, so that the pressure hammer 234 is disengaged from the stop plate 2113 and falls to the feed port 2115 by gravity.

[0049] This design features a vertically distributed pre-entry zone 2111 and a main entry zone 2112 at the opening of the smelting cavity 211. Metal passes through the pre-entry zone 2111 and then through the main entry zone 2112 into the smelting cavity 211. The pre-entry zone 2111 is equipped with a stop plate 2113. When the pressure hammer 234 enters the smelting cavity 211, it is briefly placed on the stop plate 2113. At this time, the winding driver 235 can be activated, driving the winding wheel 232 to rotate, causing the lifting rope 233 to unwind. Because the pressure hammer 234 is placed on the stop plate 2113, the unwinding lifting rope 233 will slacken, allowing the unwinding process to proceed. Once the length reaches the specified value, the horizontal conveying mechanism 22 can be activated. The horizontal conveying mechanism 22 drives the moving base 231 to move. Since the feed port 2115 is located diagonally below the stop plate 2113, when the moving base 231 moves towards the feed port 2115, the lifting rope 233 drives the pressure hammer 234 to move until it detaches from the stop plate 2113. Under the action of gravity, the pressure hammer 234 falls to the feed port 2115. The pressure hammer 234 finally presses against the metal staying in the feed port 2115, thereby deforming and displacing the metal so that it passes through the feed port 2115 and falls into the melting cavity 211. Therefore, the pressure hammer 234 pushes the metal into the feed port 2115 by gravity. Its force is large and can significantly reduce labor intensity.

[0050] Optimally, the plurality of pressure plates 2114 are tilted so that the inner diameter of the feed inlet 2115 gradually decreases from high to low.

[0051] When multiple pressure plates 2114 are tilted, the pressure plates 2114 surround each other to form a feed inlet 2115. The inside of the feed inlet 2115 forms an opening structure with an inner diameter that gradually decreases from high to low. When metal is placed into the opening of the melting cavity 211, it will be guided into the feed inlet 2115 along the length of the pressure plates 2114 under the action of gravity. At the same time, when the pressure hammer 234 falls naturally to press the metal, some of the metal deforms to a certain extent when passing through the lower end of the feed inlet 2115. The metal is compressed to a shrinking shape, making it easier to melt into the molten metal.

[0052] Optimally, the outer contour of the hammer placement cavity 212 extends into the melting inner cavity 211, and the opening of the melting inner cavity 211 is horizontally aligned with the opening of the hammer placement cavity 212.

[0053] In this embodiment, the melting chamber 211 and the hammer placement chamber 212 are preferably designed to be close to each other. The outer contour of the hammer placement chamber 212 extends into the melting chamber 211, and the melting chamber 211 can provide heat to the hammer placement chamber 212, so that the temperature of the hammer placement chamber 212 is slightly lower than that of the melting chamber 211. The temperature of the pressure hammer 234 placed in the hammer placement chamber 212 is slightly lower than that of the melting chamber 211. Therefore, after the pressure hammer 234 is transferred from the hammer placement chamber 212 to the melting chamber 211, when the pressure hammer 234 presses the metal in the feed port 2115, the pressure hammer 234 can preheat the metal in the feed port 2115 to a certain extent, which can reduce the deformation resistance of the metal and make the metal easier to plastically deform.

[0054] Alternatively, one end of the stop plate 2113 is connected to the inner wall of the pre-entry area 2111, and the other end of the stop plate 2113 is provided with an inclined surface 2116.

[0055] The stop plate 2113 is provided with an inclined surface 2116. On the one hand, it can reduce the horizontal span of the stop plate 2113, and when the metal falls on the stop plate 2113, it can also fall along the inclined surface 2116 to the feed port 2115. On the other hand, after the pressure hammer 234 is horizontal to the inclined surface 2116 of the stop plate 2113, the inclined surface 2116 can guide the pressure hammer 234 to fall to the feed port 2115, so that the pressure hammer 234 falls more accurately to the designated position.

[0056] Alternatively, the stop plate 2113 can be optimized to transition between its bottom surface and the inclined surface 2116 via an arc-shaped surface 2117.

[0057] The arc-shaped surface 2117 is located at the transition position between the bottom surface of the stop plate 2113 and the inclined surface 2116. It replaces the corner of the stop plate 2113 between the bottom surface and the inclined surface 2116, which can prevent the hoisting rope 233 from contacting the corner of the stop plate 2113 after it falls, thereby avoiding wear on the hoisting rope 233 by the corner of the stop plate 2113 and improving the service life of the hoisting rope 233.

[0058] Optimally, the horizontal conveying mechanism 22 includes: a conveying screw 221, a conveying nut seat 222, a guide rod 223, and a rotation driver 224;

[0059] The lead screw 221 is positioned above the furnace body 21; the lead nut seat 222 is threaded onto the lead screw 221 and connected to the movable base 231; the guide rod 223 extends along the length of the lead screw 221, and the lead nut seat 222 is movably connected to the guide rod 223; the output end of the rotary driver 224 is connected to the lead screw 221 and is used to drive the lead screw 221 to rotate, thereby moving the lead nut seat 222 above the lead screw 221, so that the movable base 231 passes horizontally above both the melting cavity 211 and the hammer placement cavity 212.

[0060] The lead screw 221 and guide rod 223 can be fixed at any position in the factory as needed, or inside the heat preservation cover 24. The lead screw 221 has an external thread structure, and the lead nut seat 222 has an internal thread structure. The lead nut seat 222 is threadedly engaged with the lead screw 221. When the drive 224 drives the lead screw 221 to rotate, the rotation of the lead screw 221 drives the lead nut seat 222 to move, thereby driving the moving base 231 to move, so that the hammer material mechanism 23 moves above the melting cavity 211 and the hammer placement cavity 212 under the guidance of the guide rod 223.

[0061] Among them, the rotary driver 224 is a known mechanism with a driving rotation function, such as a motor, or a combination of a motor and a reducer.

[0062] Optimally, it also includes: an insulated cover 24;

[0063] The heat preservation cover 24 is disposed above the furnace body 21. The opening of the furnace body 21 and the opening of the hammer placement cavity 212 are located inside the heat preservation cover 24. The outside of the heat preservation cover 24 is provided with a switch door 241. The hammer material mechanism 23 and the horizontal conveying mechanism 22 are installed inside the heat preservation cover 24.

[0064] The heat preservation cover 24 is located above the furnace body 21 and can cover the opening of the furnace body 21 and the opening of the hammer placement cavity 212. When it is necessary to melt the metal, the switch door 241 of the heat preservation cover 24 can be opened to expose the opening of the furnace body 21 and the opening of the hammer placement cavity 212, thereby improving the heat preservation effect of the furnace body 21.

[0065] Optimally, it also includes: shelf 25;

[0066] The shelf 25 is provided with a first floor 251 and a second floor 252 from low to high; the furnace body 21 is fixed to the first floor 251, the opening of the furnace body 21 and the opening of the hammer placement cavity 212 are located on the second floor 252, and the heat preservation cover 24 is installed on the second floor 252.

[0067] This design preferably uses a shelf 25 to divide the furnace body 21 into two parts. The fixed ends of the furnace body 21 are mainly concentrated on the first floor 251. The entire furnace body 21 is located above the first floor 251 and below the second floor 252. Therefore, the high-temperature area of ​​the furnace body 21 is mainly concentrated below the second floor 252. Workers can carry out operations and prepare materials on the second floor 252. The second floor 252 has an insulation cover 24 to cover the openings of the furnace body 21 and the hammer placement cavity 212, so as to avoid excessive temperature around the pressing material.
