Description

Technical Field

[0001] The utility model belongs to the technical field of waste copper smelting, in particular to a waste copper smelting device. Background Art

[0002] Copper is a metallic chemical element and a trace element necessary for the human body. It is also the earliest metal discovered by humans. Smelting refers to melting solid metal into liquid and tempering it in a heating furnace. It is one of the casting production processes. When smelting scrap copper, scrap copper is often directly put into the smelting device. Since scrap copper has different sizes and irregular shapes, it will cause large gaps between the scrap copper when it enters the smelting device and accumulates. The gap will occupy the space inside the smelting device, which reduces the amount of scrap copper smelted at a single time, and requires multiple smelting of scrap copper, thereby reducing the efficiency of scrap copper smelting.

[0003] For example, the existing Chinese publication number is: CN207418825U, which is a waste copper smelting device, which "comprises a smelting device body, a feed port, a copper outlet, a breathable brick, a slag removal port, an additive device, a heat preservation furnace, an exhaust port, and a burner, characterized in that: a feed port is provided on the side of the smelting device body, a copper outlet is provided at the bottom of the smelting device body, and the copper outlet is connected to the heat preservation furnace."

[0004] It can be seen that the cited patent document has the problem of reducing the smelting efficiency due to the small amount of scrap copper smelted at a time. Utility Model Content

[0009] Preferably, an exhaust pipe for conveying waste gas is fixedly provided on the top surface of the smelting box, and a connecting pipe for externally connecting to a waste gas recovery device is fixedly provided at the free end of the exhaust pipe.

[0010] Preferably, a filter plate for filtering exhaust gas is fixedly provided on the inner wall of the exhaust pipe, and an air pump is installed around the connecting pipe.

[0011] Preferably, the peripheral side of the compression plate is in frictional contact with the inner wall of the compression box, and the height of the compression plate is greater than the diameter of the feed port.

[0012] Preferably, the top surface of the material guiding plate is arranged in an inclined surface, and the bottom surface of the compression plate is also arranged in an inclined surface with the top surface of the material guiding plate.

[0025] The connection method can be bonding, welding, bolt connection and other existing methods, depending on actual needs.

[0026] like Figures 1 to 4 The waste copper smelting device shown in the figure comprises a smelting box 1, the bottom or one side of the smelting box 1 may be provided with a discharge port for discharging the waste copper melt, the top surface of the smelting box 1 is fixedly provided with an exhaust pipe 11 for conveying waste gas, the free end of the exhaust pipe 11 is fixedly provided with a connecting pipe 12 for externally connecting a waste gas recovery device, the inner side wall of the exhaust pipe 11 is fixedly provided with a filter plate 14 for filtering the waste gas, and an air pump 13 is installed around the connecting pipe 12. Since the irritating waste gas of sulfur dioxide is generated during the smelting process of the waste copper, the air pump 13 can be turned on , let the air pump 13 extract the exhaust gas in the smelting box 1 into the exhaust pipe 11, and pass through the filter plate 14 to filter impurities in the exhaust gas, and the exhaust gas passing through the filter plate 14 will enter the connecting pipe 12, and be transported to the external exhaust gas recovery device through the connecting pipe 12 for treatment. Desulfurization liquid can be put into the exhaust gas recovery device to achieve the purpose of desulfurization of the exhaust gas, and the installation position of the air pump 13 is selected according to the actual situation, and it is only necessary to ensure that the air pump 13 can extract the exhaust gas in the smelting box 1 to the exhaust pipe 11.

[0027] A compression box 2 is fixedly provided on one side of the smelting box 1 through a fixed block, and a feeding port 3 for putting in scrap copper is provided on a side of the compression box 2 away from the smelting box 1, and a discharge port 4 for discharging scrap copper is provided on the bottom surface of the compression box 2. A feeding box 10 is provided on one side of the smelting box 1 and below the compression box 2. The feeding box 10 is arranged inclined upward, and the free end of the feeding box 10 is fixedly connected to the bottom surface of the compression box 2. The inner cavity of the feeding box 10 is hollowed out, and the two ends of the feeding box 10 are respectively connected with one side surface of the smelting box 1 and the bottom surface of the compression box 2. The scrap copper to be smelted can be put into the compression box 2 through the feeding port 3 for compression, thereby achieving the purpose of reducing the occupied space. After all the scrap copper to be smelted is put into the compression box 2 for compression, the scrap copper can be moved into the feeding box 10 through the discharge port 4, and moved into the smelting box 1 through the feeding box 10 for smelting operation.

[0028] A guide plate 5 is fixedly arranged on the bottom surface of the inner cavity of the compression box 2. The guide plate 5 is arranged in a circular array along the outer side of the discharge port 4. The top surface of the guide plate 5 is arranged in an inclined surface, which can better transport the waste copper to the discharge port 4. A hydraulic cylinder 6 is fixedly arranged on the top surface of the compression box 2. The piston rod of the hydraulic cylinder 6 penetrates through the compression box 2. A compression plate 7 for compressing the waste copper is fixedly arranged. The bottom surface of the compression plate 7 is also arranged in an inclined surface with the top surface of the guide plate 5. By opening the hydraulic cylinder 6, the hydraulic cylinder 6 can drive the compression plate 7 to perform longitudinal reciprocating motion in the inner cavity of the compression box 2, so that the compression plate 7 can repeatedly squeeze the waste copper to achieve the purpose of compression, and the discharge port 4 is provided with a chute 8, one side of the chute 8 penetrates to one side of the compression box 2, and the inner cavity of the chute 8 is slidably provided with a baffle 9 for limiting the waste copper.

After all the waste copper is compressed, the baffle 9 is pulled to move the baffle 9 in the inner cavity of the chute 8, so that the baffle 9 can be removed from the inner cavity of the discharge port 4, so that the waste copper can be transported to the smelting box 1 through the discharge port 4, thereby avoiding the problem that irregular waste copper will occupy the space inside the smelting box 1 and the amount of waste copper smelted in a single time is low, thereby improving the efficiency of smelting the waste copper.

[0029] The baffle plate 9 can be driven and moved by an external cylinder, which is convenient for the staff to operate and also prevents the staff from being unable to pull the baffle plate 9 .

[0030] The circumferential side of the compression plate 7 is in frictional contact with the inner wall of the compression box 2. The height of the compression plate 7 is greater than the diameter of the feed port 3. That is, when the scrap copper is smelted, the hydraulic cylinder 6 can drive the compression plate 7 to move to one side of the feed port 3 to restrict the feed port 3, and cooperate with the baffle 9 to restrict the discharge port 4 to prevent exhaust gas from being discharged from the feed port 3.

[0031] Working principle:

[0032] The scrap copper smelting device puts the scrap copper to be smelted into the compression box 2 through the feed port 3, and starts the hydraulic cylinder 6, so that the hydraulic cylinder 6 repeatedly drives the compression plate 7 to perform longitudinal reciprocating motion, so that the compression plate 7 can repeatedly squeeze the scrap copper dropped onto the top surface of the guide plate 5 to achieve the compression effect, and cooperates with the longitudinal reciprocating motion of the compression plate 7 to continuously compress the scrap copper put in later. After all the scrap copper to be smelted is put into the compression box 2 and compressed, the baffle plate 9 is dragged to move the baffle plate 9 from the inner cavity of the chute 8, so that the baffle plate 9 can be moved out of the discharge port 4, so that the scrap copper can move to the discharge port 4 through the inclined guide plate 5, and fall into the feeding box 10 through the discharge port 4, and cooperate with the inclined setting of the feeding box 10 to move the compressed scrap copper into the smelting box 1 for smelting, thereby avoiding the problem that irregular scrap copper occupies the space inside the smelting box 1 and the amount of scrap copper smelted at a single time is low, thereby improving the efficiency of scrap copper smelting.
