Description

Technical Field

[0001] This utility model relates to the field of low-temperature smelting technology, and in particular to a low-temperature smelting apparatus for high direct yield of lead grid. Background Technology

[0002] A tilting cryogenic furnace is a device that combines tilting functionality with cryogenic melting technology. It is primarily used for melting metals or other materials. Its working principle is based on heating the material at a low temperature until it reaches its melting point and melts, while the tilting motion of the furnace body optimizes the melting process. It includes the furnace body, heating system, and tilting mechanism. In most tilting cryogenic furnaces, the molten metal easily overflows during tilting.

[0003] Chinese patent application CN201520032091.7 discloses a low-temperature energy-saving aluminum smelting device. The key technical points of the device are: This utility model changes the traditional smelting furnace structure and smelting combustion method, and uses natural gas as fuel, which can effectively reduce the melting temperature of aluminum blocks, save energy consumption, and make full use of waste heat. It is both clean production and zero environmental pollution, and saves energy, reduces production costs, and improves economic efficiency, thus having very high practical application value.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: most tilting cryogenic smelting furnaces, due to excessive tilting angle or speed, easily cause the smelted lead liquid to overflow during tilting; and after the smelting furnace is tilted after discharge, some lead liquid usually remains inside the discharge port and its connected pipes. This residual lead liquid may leak from the discharge port to the ground due to gravity, thus causing pollution to the working environment and wasting lead resources. Therefore, a cryogenic smelting device with high direct recovery rate of lead grid is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the excessive or rapid tilting angle of most tilting cryogenic furnaces, which cause lead molten metal to leak from the discharge port and its connected pipes onto the ground, resulting in pollution of the working environment and waste of lead resources. Therefore, this invention proposes a cryogenic smelting device with high direct recovery rate of lead grid.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a low-temperature smelting device for high direct yield of lead grid, comprising a smelting furnace, with protective devices on both sides of the smelting furnace, each protective device comprising two connecting rods fixedly connected to both sides of the smelting furnace, a long plate rotatably connected to the end of each connecting rod away from the smelting furnace, a short rod fixedly connected to one side of the long plate, a collection bin rotatably connected to the ends of the two short rods close to each other, a circular plate fixedly connected to one side of the long plate, a circular rod fixedly connected to the surface of the circular plate, a positioning plate rotatably connected to the end of the circular rod away from the circular plate, a long rod slidably inserted into the positioning plate, two sliding holes formed on the surface of the circular plate, the arc surface of the long rod slidably connected to the sliding holes of the circular plate, and a positioning groove formed on one side of the collection bin.

[0007] The aforementioned components achieve the following effects: by setting up a protective device, the molten lead overflowing from the discharge port during the turning process is collected. This prevents the molten lead from easily overflowing when workers turn the smelting furnace to pour out the molten lead due to excessive or rapid turning angles. It also prevents the molten lead from leaving some residue inside the discharge port and its connected pipes after the furnace is turned over. This residue may leak onto the ground due to gravity, causing pollution to the working environment and wasting lead resources. This improves the practicality of the device.

[0008] Preferably, a spring is fitted onto the arc surface of the long rod, and the two ends of the spring are fixedly connected to the positioning plate and the long rod, respectively.

[0009] The effect achieved by the above-mentioned components is to prevent the long rod from sliding unintentionally due to the shaking caused by the operator turning the smelting furnace, which could lead to the long rod sliding out of the positioning slot of the collection bin, thus improving the stability of the device.

[0010] Preferably, a torsion spring is fitted onto the arc surface of the round rod, and the two ends of the torsion spring are fixedly connected to the round plate and the positioning plate, respectively.

[0011] The aforementioned components achieve the following effects: the positioning plate can be quickly positioned, reducing the number of steps required by the operator. This avoids situations where the operator cannot align the long rod with the sliding hole of the round plate in one go, thus requiring further adjustments and increasing the operator's workload.

[0012] Preferably, a connecting block is fixedly connected to the surface of the circular plate, a screw is threaded into the connecting block, and a threaded groove is formed on the arc surface of the long rod.

[0013] The effect achieved by the above components is that the screw achieves the effect of limiting the long rod, avoiding the situation where the screw rubs against the surface of the circular plate when the operator rotates the positioning plate, thus preventing the screw from wearing out.

[0014] Preferably, the surface of the smelting furnace is provided with a filtering device, the filtering device including two U-shaped frames, both of which are fixedly connected to the surface of the smelting furnace, an L-shaped frame is slidably inserted into the inner surface of the U-shaped frame, and a filter plate is fixedly connected to the surface of the two L-shaped frames, the surface of the filter plate being slidably connected to the smelting furnace.

[0015] The effect achieved by the above-mentioned components is as follows: by setting up a filtration device, various solid impurities generated during the lead grid smelting process can be filtered out, such as incompletely melted substances, slag particles, and refractory material fragments. This effectively intercepts these solid impurities and prevents them from entering the molten lead. It avoids the situation where various solid impurities generated during the lead grid smelting process, if not cleaned in time, will gradually mix into the molten lead, thereby reducing the quality of the molten lead and affecting the performance of the final lead product, thus improving the stability of product quality.

[0016] Preferably, a plurality of fixing slots are provided on one side of the U-shaped frame, a fixing rod is fixedly connected to one side of the L-shaped frame, a fixing plate is fixedly connected to the end of the fixing rod away from the L-shaped frame, and a sliding rod is slidably inserted into the fixing plate.

[0017] The effect achieved by the above-mentioned components is that the staff can adjust the position of the filter plate in real time according to the height of the molten lead after melting, thus avoiding the situation where the molten lead covers the filter plate and some impurities are mixed into the molten lead during the subsequent dissolution process.

[0018] Preferably, a limiting ring is fixedly connected to the arc surface of the slide rod, and the size of the slide rod is adapted to the size of the U-shaped frame fixing groove.

[0019] The effect achieved by the above components is to prevent the sliding rod from unintentionally sliding within the fixed plate and falling off when the L-shaped frame is adjusted by the operator, thus improving the practicality of the device.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] 1. In this utility model, by setting up a protective device, the effect of collecting the lead liquid overflowing from the discharge port during the turning process is achieved. This avoids the situation where the lead liquid easily overflows when workers turn the smelting furnace to pour out the smelted lead liquid due to the turning angle being too large or too fast. Also, after the smelting furnace is turned over after discharge, some lead liquid usually remains inside the discharge port and its connected pipes. This residual lead liquid may leak from the discharge port to the ground due to gravity, which may cause pollution to the working environment and waste of lead resources. This improves the practicality of the device.

[0022] 2. In this utility model, by setting up a filtration device, various solid impurities generated during the lead grid smelting process can be filtered out, such as incompletely melted substances, slag particles, and refractory material fragments. This effectively intercepts these solid impurities and prevents them from entering the molten lead. It avoids the situation where various solid impurities generated during the lead grid smelting process, if not cleaned in time, will gradually mix into the molten lead, thereby reducing the quality of the molten lead and affecting the performance of the final lead product, thus improving the stability of product quality.

[0029] Reference Figure 1As shown, this utility model provides a technical solution: a low-temperature smelting device with high direct recovery rate for lead grids, including a smelting furnace 1. Protective devices 2 are provided on both sides of the smelting furnace 1. By setting the protective devices 2, the effect of collecting lead molten material overflowing from the discharge port during the turning process is achieved. This avoids the situation where, when workers turn the smelting furnace 1 to pour out the smelted lead molten material, the lead molten material easily overflows due to excessive turning angle or speed. Furthermore, after the smelting furnace 1 is turned after discharging, some lead molten material usually remains inside the discharge port and its connected pipes. This residual lead molten material may leak from the discharge port to the ground due to gravity, thus polluting the working environment. The occurrence of waste of lead resources and the improvement of the equipment's practicality are addressed by installing a filter device 3 on the surface of the smelting furnace 1. By setting up the filter device 3, various solid impurities generated during the lead grid smelting process can be filtered out, such as incompletely melted substances, slag particles, and refractory material fragments. This effectively intercepts these solid impurities and prevents them from entering the smelted lead liquid. This avoids the situation where various solid impurities generated during the lead grid smelting process, if not cleaned in time, will gradually mix into the lead liquid, thereby reducing the quality of the lead liquid and affecting the performance of the final lead product, thus improving the stability of product quality.

[0030] The specific setup and function of its protective device 2 and filter device 3 will be described in detail below.

[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the protective device 2 includes two connecting rods 201, which are fixedly connected to both sides of the smelting furnace 1 respectively. A long plate 202 is rotatably connected to the end of each connecting rod 201 away from the smelting furnace 1. A short rod 203 is fixedly connected to one side of the long plate 202. A collection bin 204 is rotatably connected to the ends of the two short rods 203 that are close to each other. A circular plate 205 is fixedly connected to one side of the long plate 202. A circular rod 206 is fixedly connected to the surface of the circular plate 205. A positioning plate 207 is rotatably connected to the end of the circular rod 206 away from the circular plate 205. A long rod 208 is slidably inserted into the positioning plate 207. Two sliding holes are formed on the surface of the circular plate 205. The arc surface of the long rod 208 is slidably connected to the sliding holes of the circular plate 205. The collection bin 204... A positioning groove is provided on one side. A spring 209 is fitted onto the arc surface of the long rod 208. The two ends of the spring 209 are fixedly connected to the positioning plate 207 and the long rod 208, respectively. When the operator flips the smelting furnace 1, the operator pulls the long rod 208 to slide within the positioning plate 207. At this time, the spring 209 is stretched until the long rod 208 leaves the sliding hole of the circular plate 205. The operator then pushes the positioning plate 207 to rotate on the arc surface of the circular rod 206. The positioning plate 207 drives the long rod 208 to move until the positioning plate 207 is in a horizontal state. The operator then pushes the collection bin 204 to rotate on the arc surface of the short rod 203 until the collection bin 204 is aligned with the direction of the positioning plate 207. The operator then releases the long rod 208, and the rebound force of the spring 209 drives the long rod 208 to rotate on the arc surface of the short rod 203. The long rod 208 slides within the sliding hole of the circular plate 205 until it is inserted into the positioning slot of the collection bin 204. This prevents the long rod 208 from unintentionally sliding out of the positioning slot of the collection bin 204 due to the shaking caused by the operator when flipping the smelting furnace 1, thus improving the stability of the device. A torsion spring 210 is fitted on the arc surface of the circular rod 206. The two ends of the torsion spring 210 are fixedly connected to the circular plate 205 and the positioning plate 207, respectively. After the operator flips the smelting furnace 1 to pour out the molten lead, and after a certain angle of flipping, the operator pulls the long rod 208 to slide within the positioning plate 207. At this time, the spring 209 is stretched until the long rod 208 leaves the sliding hole of the circular plate 205. The operator then pushes the collection bin 204 into the positioning slot of the short rod 206. The arc surface of rod 206 rotates until the collection chamber 204 is in a vertical position. The torque of the torsion spring 210 drives the positioning plate 207 to rotate on the arc surface of the round rod 206. The positioning plate 207 drives the long rod 208 to move until the long rod 208 is flush with the sliding hole of the round plate 205. The rebound force of the spring 209 drives the long rod 208 to slide in the sliding hole of the round plate 205 until the long rod 208 is inserted into the positioning groove of the collection chamber 204. This achieves the effect of quick positioning of the positioning plate 207, reducing the number of steps required by the operator. It avoids the situation where the operator cannot align the long rod 208 with the sliding hole of the round plate 205 in one go, requiring further adjustment and increasing the workload of the operator. A connecting block 211 is fixedly connected to the surface of the round plate 205.A screw 212 is threaded into the connecting block 211. The arc surface of the long rod 208 has a threaded groove. After the worker flips the collection chamber 204, the worker pulls the long rod 208 and slides it within the positioning plate 207 until it exits the sliding hole in the circular plate 205. The worker then rotates the screw 212 within the connecting block 211 until it enters the threaded groove of the long rod 208. At this point, the screw 212 effectively limits the movement of the long rod 208, preventing friction between the screw 212 and the surface of the circular plate 205 when the worker rotates the positioning plate 207, thus avoiding wear on the screw 212.

[0032] Reference Figure 4 and Figure 5 As shown, specifically, the filter device 3 includes two U-shaped frames 31, both of which are fixedly connected to the surface of the smelting furnace 1. An L-shaped frame 32 is slidably inserted into the inner surface of the U-shaped frame 31. Filter plates 33 are fixedly connected to the surfaces of the two L-shaped frames 32, and the surfaces of the filter plates 33 are slidably connected to the smelting furnace 1. Several fixing slots are provided on one side of the U-shaped frame 31. A fixing rod 34 is fixedly connected to one side of the L-shaped frame 32. A fixing plate 35 is fixedly connected to the end of the fixing rod 34 away from the L-shaped frame 32. A sliding rod 36 is slidably inserted into the fixing plate 35. Based on the height of the molten lead after smelting, the operator pushes the L-shaped frame 32 to slide within the U-shaped frame 31. After reaching the appropriate position, the operator pushes the sliding rod 36 to slide within the fixing plate 35 until the sliding rod 36 is inserted into the fixing slot of the U-shaped frame 31, achieving the desired effect. The position of the filter plate 33 can be adjusted in real time according to the height of the molten lead, preventing the molten lead from covering the filter plate 33 and causing impurities to mix into the molten lead during subsequent dissolution. The arc surface of the slide rod 36 is fixedly connected to the limiting ring 37. The size of the slide rod 36 is adapted to the size of the fixing groove of the U-shaped frame 31. When the operator pushes the L-shaped frame 32 to slide within the U-shaped frame 31, the slide rod 36 slides within the fixing plate 35. The slide rod 36 drives the limiting ring 37 to move until the limiting ring 37 abuts against the surface of the fixing plate 35. This prevents the slide rod 36 from unintentionally sliding within the fixing plate 35 due to shaking caused by the operator adjusting the position of the L-shaped frame 32, thus improving the practicality of the device.

[0033] Working principle: When the worker needs to tilt the smelting furnace 1 to pour out the molten lead, the worker pulls the long rod 208 to slide within the positioning plate 207. At this time, the spring 209 is stretched until the long rod 208 leaves the sliding hole of the circular plate 205. The worker then pushes the positioning plate 207 to rotate on the arc surface of the circular rod 206. The positioning plate 207 drives the long rod 208 to move until the positioning plate 207 is in a horizontal state. The worker then pushes the collection bin 204 to rotate on the arc surface of the short rod 203 until the collection bin 204 is aligned with the positioning plate. Aligning 207 with the direction of the plate, the operator releases the long rod 208. The rebound force of the spring 209 causes the long rod 208 to slide within the sliding hole of the circular plate 205 until it is inserted into the positioning groove of the collection bin 204. After the operator completes the flipping, the operator pulls the long rod 208 to slide within the positioning plate 207. At this time, the spring 209 is stretched until the long rod 208 leaves the sliding hole of the circular plate 205. The operator then rotates the screw 212 within the threaded section of the connecting block 211 until the screw 212 is inserted into the threaded groove of the long rod 208. Inside, the worker pushes the collection chamber 204 to rotate on the arc surface of the short rod 203 until the collection chamber 204 is in a vertical position. The torque of the torsion spring 210 drives the positioning plate 207 to rotate on the arc surface of the round rod 206. The positioning plate 207 drives the long rod 208 to move until the long rod 208 is flush with the sliding hole of the round plate 205. After the worker releases the screw 212 from limiting the long rod 208, the rebound force of the spring 209 drives the long rod 208 to slide in the sliding hole of the round plate 205 until the long rod 208 is inserted into the collection chamber 204. The device effectively collects molten lead that overflows from the discharge port during the turning process. This prevents the molten lead from easily overflowing when workers turn the furnace 1 to pour out the molten lead due to excessive or rapid turning angles. It also prevents the residual molten lead inside the discharge port and its connected pipes after the furnace 1 is turned over. This residual molten lead may leak from the discharge port to the ground due to gravity, causing pollution to the working environment and wasting lead resources. This improves the practicality of the device.

[0034] Workers operate the equipment for smelting. After smelting for a period of time, based on the height of the molten lead, workers push the L-shaped frame 32 to slide within the U-shaped frame 31. Once it reaches the appropriate position, workers push the slide rod 36 to slide within the fixed plate 35 until the slide rod 36 is inserted into the fixed groove of the U-shaped frame 31. This achieves the effect of filtering various solid impurities generated during the lead grid smelting process, such as incompletely melted substances, slag particles, and refractory material fragments. It effectively intercepts these solid impurities and prevents them from entering the molten lead. This avoids the situation where various solid impurities generated during the lead grid smelting process, if not cleaned in time, will gradually mix into the molten lead, thereby reducing the quality of the molten lead and affecting the performance of the final lead product, thus improving the stability of product quality.
