Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste copper recycling, specifically a dust extraction hood for waste copper melting furnaces. Background Technology
[0002] As my country's smelting and processing enterprises continue to expand, the demand for raw materials is increasing, and the supply-demand imbalance is becoming increasingly prominent. Domestic smelting capacity is rapidly expanding, and smelters will increasingly rely on scrap copper for raw materials. Sorting scrap copper facilitates its direct utilization, saves energy, reduces costs, and allows for the comprehensive utilization of alloying elements. Furthermore, scrap copper sorting also benefits recycling and trade.
[0003] When recycling and melting scrap copper, a suitable melting furnace is required. During operation, the furnace emits fumes from the feed inlet. These fumes are treated by dust removal equipment. Before treatment, the fumes are often concentrated by a dust collection hood to reduce their escape. The dust collection equipment can effectively remove more waste gas, reducing environmental pollution. Currently, the dust collection hood is located above the feed inlet. Workers need to manually open the hood door to feed the material, and then manually close it again. This not only increases the labor intensity for workers but also allows some fumes to escape during feeding, failing to effectively block the fumes. Utility Model Content
[0004] The purpose of this invention is to provide a dust extraction hood for waste copper melting furnaces to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

An L-shaped dust suction door is provided inside the opening. Multiple rotating blocks are evenly fixedly connected to one side of the L-shaped dust suction door. A rotating shaft is fixedly connected through the interior of each set of rotating blocks. Multiple fixed blocks are evenly rotatably connected to the outside of the rotating shaft. Each set of fixed blocks is fixedly connected to the cover body. A support plate is fixedly connected to one side of the cover body. A stepper motor is fixedly connected to the bottom of the support plate. The output end of the stepper motor is fixedly connected to the rotating shaft.
[0008] The lifting mechanism includes a lifting beam fixedly connected to the inner wall of the L-shaped vacuum cleaner door. The lifting beam has a through hole inside, and a fixed pulley is rotatably connected inside the lifting beam. A lifting cable passes through the through hole and passes around the fixed pulley. One end of the lifting cable is fixedly connected to a hook. A winch is fixedly connected to one side wall of the L-shaped vacuum cleaner door, and the end of the lifting cable away from the hook is fixedly connected to the output end of the winch.
[0009] As a further embodiment of this utility model: support rods are symmetrically fixedly connected to the bottom of the support plate, and the bottom of the support rods is at the same height as the bottom of the cover.
[0010] As a further embodiment of this utility model: multiple reinforcing rods are evenly fixedly connected to the inner corner of the L-shaped vacuum cleaner door, a fixing rod is fixedly connected to one side of the hanging beam, and the end of the fixing rod away from the hanging beam is fixedly connected to the L-shaped vacuum cleaner door.
[0011] As a further embodiment of this utility model: a diagonal brace is fixedly connected to the bottom of the hanging beam, and the end of the diagonal brace away from the hanging beam is fixedly connected to the L-shaped dust collection hood door.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] With the above-described structure, this invention utilizes the coordinated operation of an L-shaped dust extraction door, a stepper motor, a lifting beam, and a winch. When the stepper motor starts, it drives the rotating shaft and the L-shaped dust extraction door to rotate, thus controlling the opening and closing of the door. The rotation of the L-shaped door causes the lifting beam and hook to rotate accordingly. When the L-shaped door opens, the hook moves out of the enclosure, allowing the clamp holding the copper material to be hooked onto it. When the L-shaped door closes, it drives the lifting beam to rotate, moving the copper material above the furnace inlet. Then, simply releasing the clamp allows the copper material to be added into the furnace inlet. This design ensures that the L-shaped dust extraction door opens and closes promptly with the lifting beam during copper lifting, eliminating the need for manual closing and effectively blocking smoke and dust.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0023] Please see Figure 1-4 A dust collection hood for a scrap copper melting furnace includes a shielding mechanism 1. The shielding mechanism 1 includes a hood body 101, which is positioned above the furnace feed inlet to shield the emitted fumes. A connected fume pipe 102 is fixedly connected to the top of the hood body 101, and is connected to fume treatment equipment, allowing the fumes shielded by the hood body 101 to be discharged into the fume treatment equipment for processing. A passage opening 104 is provided at one corner of the hood body 101 to facilitate the passage of copper material during feeding. An L-shaped dust collection door 103 is provided inside the passage opening 104 to close the passage opening 104, thereby effectively shielding the fumes.
[0024] Multiple reinforcing rods 209 are evenly fixedly connected to the corners of the inner wall of the L-shaped vacuum cleaner door 103. The reinforcing rods 209 can improve the strength of the L-shaped vacuum cleaner door 103 and reduce the probability of deformation. The lifting mechanism 2 includes a lifting beam 201 fixedly connected to the inner wall of the L-shaped vacuum cleaner door 103. The bottom of the lifting beam 201 is fixedly connected to a diagonal brace 207. The end of the diagonal brace 207 away from the lifting beam 201 is fixedly connected to the L-shaped vacuum cleaner door 103. The diagonal brace 207 is used to further connect and fix the lifting beam 201 and the L-shaped vacuum cleaner door 103, thereby improving the connection stability between the lifting beam 201 and the L-shaped vacuum cleaner door 103. A fixing rod 208 is fixedly connected to one side of the hanging beam 201. The end of the fixing rod 208 away from the hanging beam 201 is fixedly connected to the L-shaped dust collection door 103. The setting of the hanging beam 201 can improve the stability of the hanging beam 201.
[0025] The lifting beam 201 has a through hole 202 inside, and a fixed pulley 203 is rotatably connected inside the lifting beam 201. A lifting cable 204 passes through the through hole 202. The through hole 202 is designed for the lifting cable 204 to pass through. The lifting cable 204 passes over the fixed pulley 203, which guides the lifting cable 204. One end of the lifting cable 204 is fixedly connected to a hook 205, which is used to hook the clamp holding the copper material. A guide rod 210 is provided on one side of the L-shaped dust collection door 103. Both ends of the guide rod 210 are rotatably connected to mounting blocks 211, which are fixedly connected to the L-shaped dust collection door 103. The lifting cable 204 passes over the outside of the guide rod 210, which guides the lifting cable 204.
[0026] A winch 212 is fixedly connected to one side wall of the L-shaped dust extraction door 103. The end of the lifting cable 204 away from the hook 205 is fixedly connected to the output end of the winch 212. The winch 212 is used to wind and unwind the lifting cable 204 when starting work, thereby lifting and unwinding the copper material. A baffle plate 206 is fixedly connected to the outside of the lifting cable 204. The baffle plate 206 corresponds to the through hole 202. The baffle plate 206 is used to move the lifting cable 204 synchronously, so that when the baffle plate 206 moves to be lower than the lifting beam 201, it can block the through hole 202, thereby reducing the probability of flue gas being discharged from the through hole 202.
[0027] Multiple rotating blocks 105 are evenly fixedly connected to one side of the L-shaped vacuum cleaner door 103. A rotating shaft 107 is fixedly connected through the interior of each rotating block 105. The rotating shaft 107 is used to drive the rotating blocks 105 and the L-shaped vacuum cleaner door 103 to rotate when they rotate. Multiple fixing blocks 106 are evenly rotatably connected to the outside of the rotating shaft 107. Each group of fixing blocks 106 is fixedly connected to the cover body 101. A support plate 108 is fixedly connected to one side of the cover body 101. Support rods 110 are symmetrically fixedly connected to the bottom of the support plate 108. The bottom of the support rods 110 is at the same height as the bottom of the cover body 101. The support rods 110 are used to further support the support plate 108, thereby improving the stability of the support plate 108. A stepper motor 109 is fixedly connected to the bottom of the support plate 108. The output end of the stepper motor 109 is fixedly connected to the rotating shaft 107. The stepper motor 109 is used to drive the rotating shaft 107 to rotate when the machine starts working.
[0028] In use, the hood 101 is installed above the feeding port of the scrap copper melting furnace, and the dust pipe 102 is connected to the input end of the dust treatment equipment. This allows the dust generated during the melting furnace operation to be guided by the hood 101 into the dust pipe 102, and finally discharged into the dust treatment equipment for processing. When scrap copper needs to be added to the feeding port of the melting furnace, the stepper motor 109 can be started. When the stepper motor 109 starts working, it drives the rotating shaft 107 to rotate. When the rotating shaft 107 rotates, it drives each set of rotating blocks 105 and the L-shaped dust suction door 103 to rotate as well, so that the passage 104 is opened. When the L-shaped dust suction door 103 rotates, it drives the lifting beam 201 and the hook 205 to rotate as well, until the hook 205 is adjusted to the top of the copper material to be added. Then, the winch 212 is started, so that the winch 212... When starting the operation, the wound sling 204 can be released, causing the hook 205 to move downwards. Then, the clamp is used to hold the copper material to be added, and the clamp is hooked and fixed on the hook 205. Then, the winch 212 is started, so that the winch 212 winds the sling 204 when starting the operation, so that the sling 204 drives the hook 205, the clamp and the copper material held by the clamp to move upwards, thereby lifting the copper material. At the same time, the stepper motor 109 is started again, thereby driving the rotating shaft 107 and the L-shaped dust suction door 103 to rotate until the L-shaped dust suction door 103 is rotated and adjusted to the inside of the passage 104. The lifted copper material is rotated with the L-shaped dust suction door 103 and the lifting beam 201 to the top of the feed port of the melting furnace. Then, the clamp is released, and the copper material can be put into the feed port of the melting furnace, completing the addition of copper material.
