Description

Technical Field

[0001] This utility model relates to the field of metal smelting technology, specifically to a pre-weighing alarm device for a copper electrolysis residual electrode crushing unit. Background Technology

[0002] In copper electrolysis production, residual electrodes refer to the portion remaining on the anode plate after a certain period of electrolysis. The handling of residual electrodes is a crucial step in copper electrolysis production, directly impacting production efficiency and product quality. Due to differences in the chemical composition of the anode plates, under the same electrolysis conditions, some residual electrodes may dissolve unevenly, resulting in inconsistent thicknesses. This makes it difficult to accurately judge the thickness manually, leading to the incorporation of thicker residual electrodes during anode plate crushing. When these thicker plates enter the crushing chamber, they become too thick to be effectively torn, causing the crusher to jam, trip, and frequently shut down, preventing normal operation. Furthermore, removing thick residual electrodes from the crushing chamber is not only difficult and time-consuming but also poses significant safety risks, ultimately reducing production efficiency and increasing costs. Utility Model Content

[0003] The purpose of this utility model is to provide a pre-weighing alarm device for copper electrolysis residual electrode crushing units that can accurately weigh residual electrode plates, automatically alarm in real time, improve crushing efficiency, and is easy to operate. This device solves the technical problems in traditional copper electrolysis production where the thickness of residual electrode plates is uneven, making it difficult to accurately judge manually. This leads to excessively heavy residual electrode plates entering the crusher, causing frequent jamming and power tripping of the crusher, which in turn causes equipment shutdown, production interruption, and safety risks faced by operators when handling thick residual electrodes.

[0004] To solve the above technical problems, the solution adopted by this utility model is as follows:

[0005] A pre-weighing alarm device for a copper electrolysis residual electrode crushing unit, used for weighing residual electrode plates, includes a conveyor support, a conveyor chain, a module support, a weighing module, a movable slider, a control box, and an alarm device. Two conveyor supports are provided and symmetrically installed. The conveyor chain is located directly above the conveyor supports. The module support is fixedly installed on the outer side of the upper end of the conveyor supports. The weighing module is located at the upper end of the module support. The movable slider is located at the top end of the weighing module near the top of the conveyor chain. The control box and the alarm device are fixedly installed on the outer side of the upper end of one of the conveyor supports. A weighing transmitter is installed inside the control box. The weighing module is electrically connected to the weighing transmitter. The entire device is powered by an external power source, and the control box is controlled by an external control system.

[0006] This device is installed during the conveying process of the residual electrode plates to the crushing unit for crushing. The residual electrode plates are conveyed by a conveyor chain, which can stop at the required position. It is also equipped with chain hooks to stabilize the residual electrode plates and prevent them from shifting during the conveying process. The module brackets are installed on both sides of the chain hook stop position.

[0007] When the residual electrode plates are conveyed to this device, they continue to be conveyed via the conveyor chain and chain hooks. When they reach the weighing module, the tabs of the residual electrode plates detach from the chain and remain on the moving slider. The moving slider transfers the weight of the residual electrode plates to the weighing module, which weighs them and transmits the data to the weighing transmitter in the control box. The weight signal is processed and converted, and then transmitted to the external control system for judgment. When the weighed weight exceeds the set weight, the control system controls the conveyor chain to stop running and activates the alarm device to alert the operator. The operator confirms and takes action to prevent the overweight residual electrode plates from continuing to be conveyed, thus avoiding them entering the crushing chamber and affecting the crusher. If the weight does not exceed the set weight, the control system controls the conveyor chain to continue conveying, and the chain hooks on the conveyor chain pull the residual electrode plates down the moving slider, allowing them to continue to be conveyed into the crushing chamber for crushing.

[0008] Furthermore, the module support includes a support block, a connecting plate, connecting bolts, and fixing nuts; the support block is fixedly installed at the upper end of the conveying support; the connecting plate is located at the top of the support block; two fixing nuts are provided and fixedly installed at the bottom of the support block; the connecting bolts match the fixing nuts and pass through the support block to connect with the connecting plate; the weighing module is located inside the connecting plate.

[0009] The support block is fixedly installed on one side of the conveyor chain hook on the conveyor support. By rotating the connecting bolts, the connecting plate moves up and down. By vertically fine-tuning the height of the connecting plate, the height of the weighing module inside the connecting plate and the moving slider above the weighing module can be adjusted, so that the upper surface of the sliding block is in close contact with the surface of the irregular electrode tabs, eliminating weighing errors caused by poor contact and ensuring accurate weighing. The two connecting bolts ensure that the connecting plate is placed above the support block, preventing it from falling off the support block. The whole system is easy to disassemble. The electrode tabs are conveyed to the moving slider by the conveyor chain and the upper chain hook, and weighed by the weighing module. The signal detected by the weighing module is transmitted to the weighing transmitter for signal conversion, and then transmitted to the external control system for binding.

[0010] Furthermore, the weighing module includes a weighing sensor, an upper base plate, and fixing bolts; the weighing sensor extends into the interior of the connecting plate; the upper base plate is fixed to the top of the connecting plate by the fixing bolts; the movable slider is T-shaped when viewed from the front, with the upper end resembling a trapezoid and the lower end passing through the upper base plate and extending into the connecting plate to contact the weighing sensor.

[0011] The upper base plate is fixed above the connecting plate by fixing bolts to protect the load cell inside the connecting plate. The inclined angle of the trapezoidal sides of the upper end of the "T"-shaped moving slider facilitates the sliding of the residual electrode plate onto the upper surface of the connecting plate. When the weighing ends, the chain hook can easily drive the residual electrode plate to slide down from the moving slider into the conveyor chain. The lower end of the moving slider contacts the top surface of the load cell. The weight of the residual electrode plate is transmitted to the load cell through the moving slider. The load cell transmits the signal to the weighing transmitter for signal conversion and then to the external control system.

[0012] Furthermore, the upper surface of the movable slider is higher than the conveyor chain. The upper surface of the movable slider is higher than the residual electrode conveyor chain, and its bottom end is connected to the weighing sensor of the weighing module. After the residual electrode is conveyed onto the movable slider, it just detaches from the chain and rests on the upper surface of the movable slider. This ensures that the residual electrode can transfer its weight to the weighing sensor through the movable slider, avoiding the residual electrode directly pressing against the upper base plate of the weighing module, which could cause the weighing sensor to be unable to weigh.

[0013] Furthermore, the alarm device includes an alarm light and a circular mounting bracket; the circular mounting bracket is fixedly installed on the outer side of one end of the upper part of the conveying bracket; the alarm light is fixedly installed on the circular mounting bracket. The alarm light has a built-in buzzer that can simultaneously emit light to sound an alarm, notifying the operator to remove the excessively heavy residual plate to prevent it from entering the crushing chamber of the crusher unit and causing the equipment to stop.

[0014] The working principle of this utility model is as follows:

[0015] In operation, the weight of the residual electrode plate is first set. Residual electrode plates exceeding the system's set weight are considered overweight. The residual electrode plates are transported via conveyor chains on both sides of the conveyor supports and their built-in hooks. The residual electrode plates are conveyed to the movable slider, which slides along the trapezoidal side of the "T"-shaped movable slider at an inclined angle onto the upper surface of the connecting plate. The connecting plates at both ends bear the weight of the residual electrode plates and transmit it to the load cells. The load cells perform real-time weighing and transmit the detected data to the weighing transmitter inside the control box for signal conversion and transmission to the external control unit. The system determines whether the residual electrode plate is overweight. If it is not overweight, the residual electrode plate is driven by a chain hook to slide down the inclined angle on the other side of the trapezoidal upper end of the "T"-shaped moving slider, and slides onto the conveyor chain for conveying to the crushing unit for crushing. If the residual electrode plate is overweight, the control system controls the conveyor chain to stop conveying and controls the alarm device to sound and light up to alarm, notifying the operator to remove the overweight residual electrode plate. For the irregular tabs of the residual electrode plate, the height of the weighing module on the connecting plate can be adjusted by rotating the connecting bolts to ensure that the moving slider and the tabs of the residual electrode plate are in close contact, eliminating the weighing deviation caused by the unevenness of the plate surface.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses a weighing module and a moving slider to weigh the residual electrode plate in real time and triggers an alarm, allowing operators to promptly and accurately detect thick residual electrodes. This avoids the possibility of thick residual electrodes entering the crushing chamber and causing equipment downtime, effectively reducing the time spent handling thick residual electrodes and production interruptions, improving crushing efficiency by approximately 20%, and reducing the frequency of crusher maintenance. 2. The moving slider of this utility model allows the residual electrode plate to detach from the chain, preventing abnormal force on the weighing sensor and ensuring weighing accuracy. The module bracket can be vertically fine-tuned via connecting bolts to ensure that the moving slider at the top of the weighing module above the connecting plate tightly contacts the electrode lugs of the residual electrode plate, eliminating weighing errors caused by poor contact and guaranteeing accurate weighing.

[0025] The following is a detailed description of the pre-weighing alarm device for a copper electrolysis residual electrode crusher unit according to the present invention, with reference to the accompanying drawings: Example 1

[0026] A pre-weighing alarm device for a copper electrolysis residual electrode crushing unit, used for weighing residual electrode plates 9, includes a conveyor support 1, a conveyor chain 2, a module support 3, a weighing module 4, a movable slider 5, a control box 7, and an alarm device 8; two conveyor supports 1 are provided and installed symmetrically; the conveyor chain 2 is located directly above the conveyor support 1; the module support 3 is fixedly installed on the outer side of the upper end of the conveyor support 1; the weighing module 4 is located at the upper end of the module support 3; the movable slider 5 is located at the top end of the weighing module 4 near the top of the conveyor chain 2; the control box 7 and the alarm device 8 are fixedly installed on the outer side of the upper end of one of the conveyor supports 1; a weighing transmitter 6 is provided inside the control box 7; the weighing module 4 is electrically connected to the weighing transmitter 6.

[0027] The working principle of this embodiment is as follows:

[0028] The control system sets a weight threshold for the residual electrode plate 9 based on the original anode plate's weight. The set residual electrode rate is 18%. For example, for a 250kg anode plate, a residual electrode plate weighing over 48% is considered overweight. The residual electrode plate 9 is transported via the conveyor chain 2 on the conveyor support 1 and its built-in hooks. When it reaches the weighing module 4, the electrode tabs of the residual electrode plate 9 detach from the conveyor chain 2 and rest on the moving slider 5. The moving slider 5 transfers the weight of the residual electrode plate 9 to the weighing module 4, where it is weighed and the data is transmitted to the weighing transmitter 6 in the control box 7, which then transmits the weight signal. The data is processed and converted, and then transmitted to an external control system for judgment. When the weighed weight exceeds the set weight, the control system controls the conveyor chain 2 to stop running and controls the alarm device 8 to sound an alarm, reminding the operator. After the operator confirms and handles the situation, the overweight residual plate 9 is prevented from continuing to be conveyed into the crushing chamber of the crusher unit, thus preventing it from affecting the crusher. If the weight does not exceed the set weight, the control system controls the conveyor chain 2 to continue conveying the residual plate 9. The residual plate 9 is driven down the moving slider 5 by the chain hook on the conveyor chain 2 and continues to be conveyed into the crushing chamber for crushing. Example 2

The connecting plate 32 is located inside the connecting plate 32; the upper base plate 42 is fixed to the top of the connecting plate 32 by the fixing bolts 43; the movable slider 5 is T-shaped when viewed from the front, with the upper end resembling a trapezoid and the lower end passing through the upper base plate 42 and extending into the connecting plate 32 to contact the weighing sensor 41; the upper surface of the movable slider 5 is higher than the conveyor chain 2; the alarm device 8 includes an alarm light 81 and a circular mounting bracket 82; the circular mounting bracket 82 is fixedly installed on the outer side of one end of the upper part of the conveyor bracket 1; the alarm light 81 is fixedly installed on the circular mounting bracket 82.

[0030] Support block 31 is fixedly installed on one side of the hook stop position of conveyor chain 2 on conveyor bracket 1 to support connecting plate 32 and weighing device 4. The residual electrode plate 9 is moved by conveyor chain 2, sliding from the inclined angle of the trapezoidal side of the movable slider 5 to the upper plane of the movable slider 5, causing the residual electrode plate 9 to detach from conveyor chain 2 and press against the movable slider 5. The movable slider 5 transmits the weight of the residual electrode plate 9 to the weighing sensor 41 inside connecting plate 32 in real time. The weighing sensor 41 transmits the signal to the weighing transmitter 6 for signal conversion and then to the external control system for judgment. When weighing ends, the residual electrode plate 9... If plate 9 is not overweight, the chain hook will drive the residual plate 9 to slide down from the inclined angle on the other side of the trapezoid at the top of the movable slider 5 into the conveyor chain 2. If the residual plate 9 is overweight, the control system will control the conveyor chain 2 to stop conveying and control the alarm light 81 of the alarm device 8 to light up and sound to alarm, notifying the operator to remove the overweight residual plate 9. If there is an irregular residual plate 9, by rotating the connecting bolt 33, the connecting plate 32 will be moved to vertically fine adjust the height of the weighing module 4 and the movable slider 5, so that the upper surface of the movable slider 5 is in close contact with the electrode tab surface of the irregular residual plate 9, eliminating the weighing error caused by poor contact and ensuring accurate weighing.
