Description

Technical Field

[0001] This utility model relates to the field of copper matte discharge technology, and in particular to a copper-containing waste copper matte discharge device. Background Technology

[0002] During the smelting of copper-containing waste, matte is produced. This matte needs to be discharged from the smelting equipment through a specific discharge device for further processing. Currently available discharge devices for copper-containing waste matte are as follows.

[0003] In practical use, there are some shortcomings. Most existing emission devices use a single pipe for emission. Copper matte is prone to solidification during the emission process due to temperature drop, which can cause pipe blockage, affect emission efficiency, and require frequent cleaning by staff, increasing the labor intensity of the staff.

[0004] Therefore, it is necessary to provide a copper-containing waste matte discharge device to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a device for discharging copper matte waste, which solves the problems in the background art.

[0006] To address the aforementioned technical problems, this utility model provides a copper-containing waste matte discharge device. The discharge pipe serves as the core channel for matte transportation, with one end connected to a storage tank and the other end connected to the discharge port of the smelting equipment, enabling the directional transportation of matte from the smelting equipment to the storage tank. To prevent the matte from solidifying due to temperature drop during transportation, countersunk holes are provided on the surface of the discharge pipe. An electric heating rod is directly installed inside the countersunk hole, and the electric heating rod, integrated into the pipe's structure, directly heats the inside of the pipe through heat conduction, preventing matte from adhering and solidifying inside. Simultaneously, an insulation cover is installed on the outside of the discharge pipe, and the electric heating wire is installed in the space between the insulation cover and the discharge pipe, forming a nested structure of "insulation cover - electric heating wire - discharge pipe." The electric heating wire generates heat in the space, supplementing the pipe's heat on one hand, and working with the insulation cover to reduce heat loss from the pipe to the outside. Together with the electric heating rod, these components maintain a stable pipe temperature, ensuring the flow performance of the matte and preventing pipe blockage.

[0007] Preferably, the heat insulation cover is composed of a first arc-shaped plate and a second arc-shaped plate spliced ​​together. These two arc-shaped plates are symmetrically distributed on the outside of the discharge pipe, forming a complete cylindrical heat insulation cover after splicing. This split structure facilitates disassembly by workers, allowing for maintenance of internal components such as the discharge pipe and electric heating wire. To ensure worker safety, isolation rods are installed on the peripheral surfaces of both the first and second arc-shaped plates. The isolation rods extend outward perpendicular to the peripheral surfaces of the heat insulation cover, with their other ends connected to anti-scalding rods. Through the support and spacing provided by the isolation rods, the anti-scalding rods maintain a certain distance from the heat insulation cover and are evenly distributed on the outside of the heat insulation cover, effectively isolating the high temperature transmitted by the heat insulation cover and preventing workers from being burned when they get close.

[0008] Preferably, both ends of the first and second arc-shaped plates are equipped with closing plates. The closing plates directly cover the ends of the arc-shaped plates, sealing the openings of the insulation cover and enhancing the overall insulation effect. The closing plates have symmetrically distributed fixing holes. Fasteners pass through these holes to close and fix the first and second arc-shaped plates. The symmetrical fixing holes ensure even stress distribution after fastener installation, preventing the insulation cover from loosening during device operation and providing a stable working environment for the internal heating wires, thus guaranteeing the heating and insulation effect.

[0009] Preferably, the inner walls of the first and second arc-shaped plates are provided with mounting grooves. The mounting grooves are opened along the inner wall of the arc-shaped plates, and their paths are adapted to the laying path of the electric heating wire. Although the mounting grooves do not have any additional parts directly connected, they can provide a fixed installation position for the electric heating wire, preventing the electric heating wire from shifting randomly between the insulation cover and the discharge pipe, ensuring that the electric heating wire can be evenly attached to the outside of the pipe, so that the heat can be evenly transferred to the discharge pipe, and avoiding insufficient local temperature in the pipe, which would cause the copper matte to solidify.

[0010] Preferably, multiple electric heating rods are installed, and all electric heating rods are connected to the pipe through countersunk holes on the surface of the discharge pipe, maintaining independence from each other. These electric heating rods are evenly distributed on the surface of the discharge pipe, which can fully cover the main conveying area of ​​the pipe. Compared with a single electric heating rod, multiple equally distributed electric heating rods can uniformly heat the inside of the pipe, avoiding localized low temperatures that could cause the matte to solidify, further improving heating efficiency and temperature stability, and ensuring smooth matte conveying.

[0011] Preferably, multiple anti-scalding rods are installed, all of which are connected to the periphery of the heat insulation cover via isolation rods. Each rod is independent and maintains the same distance from the heat insulation cover via the isolation rods. The multiple anti-scalding rods are arranged at equal intervals along the circumference of the heat insulation cover, fully covering the outer side of the cover. Regardless of the direction from which a worker approaches the device, the anti-scalding rods insulate against the high temperature of the heat insulation cover, preventing accidental contact with high-temperature areas and maximizing worker safety.

[0012] Preferably, the electric heating rod and heating wire are equipped with corresponding temperature controllers. The temperature controllers are connected to the electric heating rods and heating wires via circuitry to form a control loop. For ease of operation and observation, the temperature controllers are typically installed on the device's control panel or in an easily observable location, connected to the electric heating rods and heating wires via wires, and do not directly contact the high-temperature pipes or insulation covers. During operation, the temperature controllers can monitor the working temperature of the electric heating rods and heating wires in real time. When the temperature exceeds a preset value, the heating power is automatically reduced; when the temperature falls below the preset value, the heating power is automatically increased, ensuring that the temperature inside the pipe remains stable within the range where matte does not solidify, thus guaranteeing discharge efficiency and avoiding energy waste.

[0013] Compared with related technologies, the copper matte discharge device for copper-containing waste provided by this utility model has the following beneficial effects: Compared to existing technologies, this copper-containing waste matte discharge device utilizes a dual heating and insulation structure. This structure involves installing electric heating rods within countersunk holes on the discharge pipe surface and simultaneously installing electric heating wires between the outer insulation cover and the discharge pipe. This effectively prevents the matte from solidifying due to temperature drops during discharge, thus preventing pipe blockage and ensuring stable discharge efficiency. Furthermore, resolving pipe blockage issues reduces the frequency of pipe cleaning operations, significantly lowering the workload for workers.

[0014] Compared to existing technologies, the insulation cover consists of a first arc-shaped plate and a second arc-shaped plate. This split structure facilitates the installation, inspection, and maintenance of the internal discharge pipes, electric heating rods, and electric heating wires, improving the ease of maintenance. Simultaneously, isolation rods are installed on the periphery of both the first and second arc-shaped plates, with anti-scalding rods at the other end. These anti-scalding rods effectively isolate the heat transferred by the insulation cover, preventing burns to personnel approaching the device and providing reliable protection for operational safety.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0019] Please refer to the following: Figure 1-5 A copper-containing waste matte discharge device is disclosed. Its core components include a discharge pipe 1, a storage tank 3, an electric heating rod 4, an insulation cover 2, and an electric heating wire 5. The connection, installation, and coordination of each component revolve around "anti-clogging and stable discharge." The discharge pipe 1 serves as the core channel for matte transportation, with flange connections at both ends for sealed connection: one end aligns with the inlet flange of the storage tank 3 via a flange plate, bolts are tightened through the flange holes, and high-temperature resistant gaskets are installed on the contact surface to prevent leakage; the other end similarly connects to the outlet flange of the smelting equipment, ensuring leak-free directional transportation of matte. To prevent matte from solidifying inside the pipe, countersunk holes 8 are drilled at preset intervals on the surface of the discharge pipe 1. The electric heating rod 4 is embedded in the holes with an interference fit, with the heating end fully extending into the pipe (to a depth of 1 / 3 to 1 / 2 of the pipe diameter). The tail connector is sealed with sealant, ensuring efficient heat conduction while preventing high-temperature media from contacting the connector. The heat insulation cover 2 is made of high-temperature resistant heat insulation material and is fixed to the outside of the discharge pipe 1 by equidistant clamps to form a uniform interlayer space of 3-5cm thickness; the electric heating wire 5 is spirally wound around the outer wall of the pipe and is fixed with high-temperature resistant clamps, which are exactly in the interlayer and do not come into contact with the inner wall of the heat insulation cover 2, thus avoiding direct heat loss. During installation, the sequence of "main first, then auxiliary; internal first, then external" is followed: First, complete the flange connection between the discharge pipe 1 and the smelting equipment and storage tank 3. Then, drill countersunk holes 8 to embed and fix the electric heating rod 4. Next, wrap and fix the electric heating wire 5. Finally, fasten the insulation cover 2 and fix it with clamps. The components work together to form a triple temperature control structure of "internal heating + external insulation + auxiliary heating": the flange connection ensures the channel is sealed, the electric heating rod 4 directly supplies heat to the inside of the pipe for rapid heating, the electric heating wire 5 provides auxiliary heating, and the insulation cover 2 reduces heat loss. The three work together to stabilize the temperature inside the pipe at 1200-1300℃ (the temperature required for the flow of copper matte), completely solving the pipe blockage problem, improving discharge efficiency, and reducing the amount of manual cleaning work. Example

[0020] Please refer to the following: Figure 1-5 The heat insulation cover 2 consists of a first arc-shaped plate 6 and a second arc-shaped plate 7, which are joined together by a mortise and tenon structure. The edges of the arc-shaped plates are respectively provided with raised edges and grooves, which are appropriately sized. When splicing, the raised edges are embedded into the grooves, which not only ensures the tightness of the splice but also reduces heat loss from the splice seam. To ensure the safety of the staff, 3-4 stainless steel isolation rods 12 are welded to the periphery of the two arc-shaped plates at equal angles (60-90°). The isolation rods 12 are perpendicular to the surface of the arc-shaped plates, and the other end is machined with external threads. They are fixed to the anti-scalding rods 13 (with pre-set threaded holes) by threaded connection, so that the anti-scalding rods 13 and the heat insulation cover 2 are kept at a fixed distance of 10-15cm to prevent the anti-scalding rods 13 from getting too hot. The installation sequence proceeds from the main body of the insulation cover 2 to the protective structure: First, the first and second arc-shaped plates 7 are joined to the base frame of the insulation cover 2 outside the discharge pipe 1 using mortise and tenon joints, ensuring a tight fit; then, isolation rods 12 are welded to the periphery of the arc-shaped plates, ensuring a firm and straight weld; finally, the anti-scalding rods 13 are screwed onto the ends of the isolation rods 12 one by one to complete the assembly. The split arc-shaped plates, combined with the mortise and tenon joints, facilitate disassembly for inspection and maintenance of the internal electric heating wires 5 and pipes; the isolation rods 12 serve both as support and heat insulation, while the anti-scalding rods 13 form an outer protective layer. Together, they insulate the outside of the insulation cover 2 from the high temperature of 80-120℃, keeping the surface temperature of the anti-scalding rods 13 at 30-40℃ to prevent workers from accidentally touching and getting burned, ensuring operational safety. Example

[0021] Please refer to the following: Figure 1-5 To further enhance the sealing and stability of the insulation cover 2, closing plates 10 are installed at both ends of the first arc-shaped plate 6 and the second arc-shaped plate 7. The closing plates 10 are circular metal plates with a diameter consistent with the outer diameter of the insulation cover 2. Bolt holes are pre-set on the edges to match the corresponding bolt holes pre-set on the ends of the arc-shaped plates. They are fixed by bolts, and high-temperature resistant heat insulation gaskets are added to the contact surfaces to reduce heat loss from the ends. The fixing holes 11 are threaded holes, with 4-6 evenly spaced on the edges of each closing plate 10. High-temperature resistant bolts and nuts are used as fasteners. After the bolts pass through the fixing holes 11, spring washers are installed between the nuts and the closing plates 10. The elasticity of the spring washers counteracts the vibration during device operation and prevents the bolts from loosening. Installation must be carried out after the arc-shaped plates are assembled: First, cover the ends of the arc-shaped plates with the closed plate 10, aligning the bolt holes; then, pass the bolts through the holes, put on the spring washers, and tighten the nuts; finally, check the tightness of all fasteners to ensure there is no looseness. The bolt connection ensures that the closed plate 10 is firmly fixed to the arc-shaped plates, and the heat insulation gasket enhances the heat insulation at the ends. The two work together to reduce heat loss and improve the overall insulation effect; at the same time, the stable end structure provides a safe heating environment for the internal electric heating wire 5, ensuring that the electric heating wire 5 provides continuous and uniform heat, maintains the stable temperature of the pipeline, and indirectly ensures smooth copper matte delivery. Example

[0022] Please refer to the following: Figure 1-5 To prevent the electric heating wire 5 from shifting during operation, mounting grooves 9 are provided on the inner walls of the first arc plate 6 and the second arc plate 7. The mounting grooves 9 adopt a U-shaped structure, with a groove width 0.5-1mm larger than the diameter of the electric heating wire 5 and a groove depth of 2-3mm. They are continuously provided along the length of the inner wall of the arc plate and are completely consistent with the winding path of the electric heating wire 5, providing precise positioning for the electric heating wire 5. The mounting groove 9 is opened simultaneously during the processing of the arc-shaped plate. During subsequent assembly, the heating wire 5 is first embedded into the mounting groove 9, and then the arc-shaped plate is spliced ​​onto the outside of the discharge pipe 1, so that the heating wire 5 fits tightly against the outer wall of the pipe. The U-shaped mounting groove 9 and the heating wire 5 are sized to form a tight limiting fit, which can effectively prevent the heating wire 5 from shifting due to thermal expansion and contraction or vibration, ensuring that the heating wire 5 fits evenly against the outer wall of the pipe, and that heat is evenly transferred to the pipe. This prevents insufficient heating in certain parts of the pipe (temperature below 1200℃) from causing the matte to solidify and blockage, and ensures heating uniformity and discharge stability. Example

[0023] Please refer to the following: Figure 1-5 To improve the uniformity and efficiency of heating within the pipeline, multiple electric heating rods 4 are installed, evenly distributed along the length of the discharge pipeline 1. Each electric heating rod 4 is inserted into an independent countersunk hole 8 via an interference fit. The depth of the countersunk hole 8 is adapted to the length of the electric heating rod 4, ensuring that the heating end extends into the pipeline to 1 / 3 to 1 / 2 of its diameter, allowing heat to be quickly transferred to the copper matte in the center of the pipeline. The terminals of all electric heating rods 4 are connected in parallel to the same control circuit via high-temperature resistant wires, ensuring that the heating power of each electric heating rod 4 is consistent, and that the failure of a single heating rod does not affect the operation of other heating rods. The installation process revolves around fixing the electric heating rods 4 and connecting the circuit: After the discharge pipe 1 is processed, countersunk holes 8 are drilled at preset intervals; the electric heating rods 4 are embedded into the holes one by one and fixed and sealed with sealant; finally, all terminals are connected in parallel with wires to the thermostat. The evenly distributed electric heating rods 4 form uniform heating points, the parallel circuit ensures synchronous heating, and the interference fit and sealant prevent leakage. The three work together to achieve uniform heating in all directions within the pipe, increasing the heating speed by 2-3 times compared to a single electric heating rod 4, ensuring that the temperature of the matte in the pipe is maintained within the flow range, avoiding local low-temperature blockage, and improving the reliability of the device. Example

[0024] Please refer to the following: Figure 1-5Multiple anti-scalding rods 13 are installed, which are made of stainless steel round tubes with low thermal conductivity. They are connected to the heat insulation cover 2 through isolation rods 12. The isolation rods 12 on the periphery of each arc plate are distributed at equal angles. After the anti-scalding rods 13 are fixed to the ends of the isolation rods 12 by threaded connection, they form a ring-shaped protective ring along the periphery of the heat insulation cover 2. A set of anti-scalding rods 13 is set every 50cm along the length of the heat insulation cover 2, corresponding one to one with the isolation rods 12, so as to achieve all-round protection on the outside of the heat insulation cover 2.

[0025] Installation must be carried out after the main body of the insulation cover 2 is fixed: First, weld the isolation rods 12 to the periphery of the arc-shaped plate to ensure accurate positioning; then, fix the anti-scalding rods 13 one by one to the ends of the isolation rods 12 using threads; finally, check the flatness of the anti-scalding rods 13 to avoid skewing. The isolation rods 12, which are distributed at equal angles, ensure that the anti-scalding rods 13 fully cover the outside of the insulation cover 2. The low thermal conductivity material and the spacing of the isolation rods 12 maximize the reduction of the temperature of the anti-scalding rods 13. The annular protective ring forms a barrier without dead angles, which not only prevents workers from contacting the high-temperature insulation cover 2, but also provides an anti-collision function through the circular tube structure, protecting the insulation cover 2 from damage by external forces. Example

[0026] Please refer to the following: Figure 1-5 The electric heating rod 4 and the electric heating wire 5 are equipped with corresponding thermostats to form an intelligent temperature control system. The thermostats are connected to the parallel circuit of the electric heating rod 4 and the circuit of the electric heating wire 5 via high-temperature resistant wires, forming independent control branches. The wires are covered with high-temperature resistant insulating sleeves to prevent high-temperature aging. The temperature sensor of the thermostat is a probe type, inserted into the pipe through the reserved hole in the discharge pipe 1, with the probe in direct contact with the copper matte to accurately monitor the temperature of the copper matte. The thermostat is installed in the operation control cabinet 1-2m away from the device. The control cabinet is waterproof and dustproof, and the operation panel has a temperature display screen and adjustment buttons for convenient real-time monitoring and adjustment by the staff. The installation follows a "sensor first, control later" sequence: First, insert the temperature sensor probe into the pre-drilled hole in the pipe and secure it in place; then, connect the temperature controller to the heating circuit with wires and cover it with an insulating sleeve; next, install the temperature controller in the control cabinet and connect it to the power supply; finally, power on and debug the system, setting a temperature threshold of 1200-1300℃. The temperature sensor provides a precise temperature signal, the independent control branch achieves refined temperature control, and the insulating sleeve and control cabinet ensure safety. These three elements work together to enable the temperature controller to automatically adjust the heating power: increasing power for rapid heating when the temperature is below the threshold, and reducing power for energy saving when the temperature is above the threshold, ensuring stable temperature within the pipe, balancing emission efficiency and energy conservation, and achieving stable and energy-efficient operation of the device.

[0027] It should be noted that the controller control circuit can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0028] The working principle of the copper-containing waste matte discharge device provided by this utility model is as follows: In the copper-containing waste smelting process, when it is necessary to discharge the matte produced in the smelting equipment, first connect one end of the discharge pipe 1 of the discharge device to the discharge port of the smelting equipment, and connect the other end to the storage box 3 to build a discharge channel for the matte. After the device is started, the electric heating rod 4 and the electric heating wire 5 begin to work under the control of the corresponding temperature controllers. The electric heating rod 4 acts directly on the inside of the discharge pipe 1, rapidly raising the temperature inside the pipe through heat conduction, ensuring that the matte remains at a suitable flow temperature after entering the pipe, and preventing the matte from adhering and solidifying due to excessively low pipe wall temperature; at the same time, the electric heating wire 5 generates heat between the insulation cover 2 and the discharge pipe 1, which on the one hand further supplements the heat to the discharge pipe 1, maintaining the overall temperature stability of the pipe, and on the other hand, the heat formed by the insulation cover 2 forms an insulation layer, reducing the loss of heat from the pipe to the external environment and reducing energy loss. Under the dual heating and insulation effect, the matte in the smelting equipment flows smoothly from the discharge port into the discharge pipe 1. Since the temperature inside the pipe is always kept within the range where the matte does not solidify, the matte can be transported in a stable flow state inside the pipe. Finally, it flows into the storage tank 3 through the other end of the discharge pipe 1, completing the entire matte discharge process. Furthermore, when maintenance is required, staff can first turn off the thermostat and wait for the device to cool down. Then, remove the fasteners from the fixing holes 11 on the surfaces of the closing plates 10 at both ends of the first and second arc-shaped plates 6 and 7, separating the first and second arc-shaped plates 6 and 7. This allows for inspection, repair, or replacement of the discharge pipe 1, electric heating rod 4, and electric heating wire 5. During routine operation, the anti-scalding rod 13 on the outside of the insulation cover 2 insulates against heat, preventing staff from accidentally touching the high-temperature insulation cover 2 and injuring themselves, thus ensuring operational safety.

[0029] It should be noted that all components used in this application are standard parts that can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets and welding that are mature in the prior art. The mechanical parts and electrical equipment adopt conventional models in the prior art. The circuit connection adopts conventional connection methods in the prior art.
