Description

Technical Field

[0001] This utility model relates to the field of refining furnace technology, and in particular to the feeding structure of refining furnace. Background Technology

[0002] A refining furnace is an industrial device used to purify metals or alloys, remove impurities, and adjust their composition. It is particularly crucial in the production of non-ferrous metals (such as aluminum and copper). It is a key device that processes the molten metal after rough refining using physical or chemical methods to reduce impurity content and improve material properties. Compared to ordinary smelting furnaces, refining furnaces offer higher impurity removal rates and significantly lower energy consumption.

[0003] When refining aluminum using a refining furnace, it is necessary to add main component metals, intermediate alloy auxiliary materials, sodium-free composite salts, and modified strengthening additives according to refining requirements. Existing feeding structures mostly convey these materials, and the proportioning control of each material component is completed before conveying. This leads to a disconnect between component proportioning and conveying control, resulting in insufficient flexibility of the feeding structure. At the same time, when multiple different materials are conveyed, some material may remain in the pipeline, resulting in inaccurate material conveying volume, which in turn affects the quality of subsequent products. Furthermore, when using the same feeding structure to convey different batches or types of materials, cross-contamination can occur between different types or batches of materials during conveying, which also affects the consistency of product quality. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a refining furnace feeding structure to solve the problems of disconnect between component ratio and conveying control and insufficient flexibility of the feeding structure.

[0005] To achieve the above objectives, the basic solution of this utility model is as follows: a refining furnace feeding structure, including a feeding tray, the feeding tray having several conveying through holes that can communicate with the refining furnace, and several conveying units, the conveying units including:

[0006] Conveyor belt;

[0007] Support transmission components that drive the conveyor belt to rotate;

[0008] Weighing instruments;

[0009] Weighing pan, which is installed on the weighing device, with one end of the conveyor belt facing the upper surface of the weighing pan.

[0010] A rotating shaft is horizontally mounted at the feed tray's conveying through-hole. The weighing device is fixedly mounted on the rotating shaft, and the weighing tray can be flipped to face the conveying through-hole.

[0011] The first controller that controls the rotation of the shaft;

[0012] A second controller that controls the rotation of the conveyor belt;

[0013] The first data transmission module for acquiring weight data measured by the weighing instrument;

[0014] The PLC controller, the first controller, the second controller, and the first data transmission module are all electrically connected to the PLC controller.

[0015] The technical principle of this utility model is as follows: When conveying materials, the materials are driven by the conveyor belt to the weighing pan. The weighing pan can cooperate with the weighing device to weigh the materials. The data obtained after weighing can be transmitted to the PLC controller by the first data transmission module. When the obtained material weight data reaches the single-batch capacity or the weight required for the corresponding material, the PLC controller controls the conveyor belt to stop through the second controller, and simultaneously controls the rotating shaft to rotate through the first controller. The rotating shaft drives the weighing pan and weighing device carrying the corresponding materials to flip. After the weighing device and weighing pan flip, the material falls out of the weighing pan and then quickly enters the refining furnace through the conveying through hole. In this process, the material is conveyed and weighed simultaneously, improving the coordination and integration of component ratio and conveying control.

[0016] Meanwhile, several conveying units can each cooperate with several conveying through holes to realize the separate conveying of different batches or different types of materials, further reducing interference between different batches or different types of materials and further improving processing accuracy.

[0017] Furthermore, the support transmission assembly includes:

[0018] The electric motor that drives the conveyor belt to rotate;

[0019] The support frame, the conveyor belt is rotatably mounted on the support frame, and the motor is fixedly mounted on the support frame;

[0020] It also includes an extended scraper, which is obliquely fixedly installed on the end of the support frame near the weighing pan. The end of the extended scraper near the weighing pan is inclined downward, and the side of the extended scraper near the support frame is in contact with the surface of the conveyor belt near the weighing pan.

[0021] With the above setup, the support frame can stably support the motor, motor, and extended scraper. When the material is conveyed to the extended scraper, because the end of the extended scraper is in contact with the surface of the conveyor belt, the extended scraper can scrape off the material on the conveyor belt and guide it to the weighing pan. The material is quickly guided to the weighing pan, and the amount of material adhering or remaining on the conveyor belt is reduced. When different types of materials are conveyed, the amount of material conveyed is more accurate.

[0022] Furthermore, the contact point between the extended scraper and the conveyor belt is located at the arc surface formed when the conveyor belt rotates.

[0023] With the above settings, the curved surface of the conveyor belt is easier to separate from the material, and it is also easier for the extended scraper to cooperate with the curved surface of the conveyor belt, so as to achieve rapid material conveying and guidance.

[0024] Furthermore, the weighing pan is box-shaped, with a feed inlet on the side of the weighing pan near the extended scraper, and a guide tube for the weighing pan is fixedly installed on the vertical side wall of the weighing pan near the conveying through hole.

[0025] With the above configuration, the box-shaped weighing pan can accommodate the material entering the feed inlet, so that the material on the weighing pan will not overflow when the weighing pan is kept horizontal; when the weighing pan is flipped, the guide tube can guide the discharge of the material, and the material can quickly enter the conveying through hole and refining furnace through the guide tube, which facilitates the containment and transportation of the material.

[0026] Furthermore, the end of the guide tube smoothly transitions to the inner wall of the weighing pan.

[0027] The above configuration allows the material in the weighing pan to flow quickly to the guide tube when the weighing pan is flipped, and then be quickly guided into the refining furnace from the guide tube.

[0028] Furthermore, it also includes:

[0029] The vibrator is fixedly installed on the weighing device, with the end of the vibrator in contact with the end of the weighing pan away from the guide tube.

[0030] A third controller that controls the vibration to turn on or off is electrically connected to the PLC controller.

[0031] With the above settings, when the weighing pan is flipped, the PLC controller controls the vibrator to start through the third controller. After the vibrator starts, it transmits the vibration force to the weighing pan and the guide tube, allowing the material to quickly and efficiently enter the refining furnace through the weighing pan and the guide tube. This can significantly reduce the amount of material residue in the weighing pan and make the transfer of different materials more accurate. Different batches or different types of materials can be transferred using the same transfer unit.

[0032] Furthermore, the lower side of the weighing device away from the guide tube is stepped. When the stepped part of the weighing device comes into contact with the feed pan, the weighing pan flips to a horizontal upward position.

[0033] With the above settings, when the weighing device is flipped to a horizontal position, the stepped part of the weighing device abuts against the feed pan to limit the movement, so that the weighing device and the weighing pan remain in a horizontal position, which facilitates accurate weighing.

[0034] Furthermore, several conveying through holes are evenly arranged around the circumference of the feed tray.

[0035] With the above setup, several conveying through holes can be matched with several conveying units one by one, which facilitates the precise arrangement of conveyor belts and support frames, and enables the separate conveying of different batches or types of materials, further reducing interference between different batches or types of materials and further improving processing accuracy.

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0042] This embodiment is basically as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model embodiment proposes a refining furnace feeding structure, including a feeding plate 10 and twelve conveying units. The feeding plate 10 is provided with twelve conveying through holes 101 that can communicate with the refining furnace. The feeding plate 10 is detachably installed on the refining furnace by bolts. Several conveying through holes 101 are evenly arranged around the circumference of the feeding plate 10.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a single conveying unit includes a conveyor belt 20, a support transmission assembly that drives the conveyor belt 20 to rotate, a weighing device 40, a weighing pan 401, a rotating shaft 403, a first controller that controls the rotation of the rotating shaft 403, a second controller that controls the rotation of the conveyor belt 20, an extension scraper 30, a first data transmission module that acquires the weight data measured by the weighing device 40, a PLC controller, a vibrator 405, and a third controller that controls the vibrator 405 to turn on or off; Figure 2 and Figure 4 As shown, the weighing pan 401 is mounted on the weighing device 40. The lower right side of the weighing device 40 is stepped. When the stepped part of the weighing device 40 abuts against the feed pan 10, the weighing pan 401 flips to a horizontally upward position. The rotating shaft 403 is horizontally rotatably mounted at the conveying through hole 101 of the feed pan 10. The weighing device 40 is fixedly mounted on the rotating shaft 403. The weighing pan 401 can be flipped to face the conveying through hole 101. At the same time, the weighing pan 401 is box-shaped. The left side of the weighing pan 401 is provided with a feed port 402. A guide tube 404 is fixedly provided on the vertical side wall of the weighing pan 401 near the conveying through hole 101. The end of the guide tube 404 smoothly transitions to the inner wall of the weighing pan 401.

[0044] like Figure 1 As shown, the support transmission assembly includes a motor (not shown) that drives the conveyor belt 20 to rotate and a support frame 201. The conveyor belt 20 is rotatably mounted on the support frame 201, and the motor is fixedly mounted on the support frame 201 by bolts. The right end of the conveyor belt 20 can be directly opposite the upper surface of the weighing pan 401. The extended scraper 30 is obliquely welded to the right end of the support frame 201. The right end of the extended scraper 30 is inclined downward, and the upper left side of the extended scraper 30 is in contact with the surface of the right end of the conveyor belt 20. The contact point between the extended scraper 30 and the conveyor belt 20 is located at the arc surface formed when the conveyor belt 20 rotates.

[0045] like Figure 2 and Figure 4 As shown, the vibrator 405 is fixedly installed on the right side of the weighing pan 40 by bolts, and the end of the vibrator 405 is in contact with the outer right side wall of the weighing pan 401.

[0046] Meanwhile, the first controller, the second controller, the first data transmission module, and the third controller are all electrically connected to the PLC controller, and the second controller is electrically connected to the motor.

[0047] In this embodiment, when the refining furnace feeding structure is in use, the preset material type, the required weight of the corresponding material, the required capacity of the weighing pan 401 per weighing, and the required number of weighings of the weighing pan 401 are first set in the PLC controller. This enables the preset of the material conveying amount and the number of conveyings, which facilitates precise control of the amount of material put into the refining furnace and makes the material input amount accurate.

[0048] The material is then placed on the conveyor belt 20, and the motor is started. The motor drives the conveyor belt 20 to rotate, causing the conveyor belt 20 to move the material towards the weighing pan 401. When the material moves to the right end of the conveyor belt 20, an extended scraper 30 is installed there. The extended scraper 30 can scrape off the material on the conveyor belt 20 and guide it into the weighing pan 401. The material enters the weighing pan 401 through the feed port 402. At this time, the weighing device 40 acquires the weight data of the weighing pan 401 and the material. The weight data acquired by the weighing device 40 is transmitted to the PLC controller through the first data transmission module. The PLC controller determines the weight of the material when the acquired weight data reaches the single-batch capacity or the corresponding material weight. When the required weight of the material is reached, the PLC controller stops the motor through the second controller and simultaneously controls the rotating shaft 403 to rotate through the first controller. The rotating shaft 403 drives the weighing pan 401 and weighing device 40, which carry the corresponding material, to rotate. After the weighing device 40 and weighing pan 401 rotate, the guide tube 404 guides the material in the weighing pan 401, so that the material quickly enters the refining furnace through the conveying through hole 101. At this time, the PLC controller starts the vibrator 405 through the third controller. After the vibrator 405 starts, it transmits the vibration force to the weighing pan 401 and the guide tube 404, so that the material quickly and efficiently enters the refining furnace through the weighing pan 401 and the guide tube 404, and can significantly reduce the amount of material residue in the weighing pan 401.

[0049] When different types of materials are conveyed, the residual amount of material in the conveyor belt 20 and weighing pan 401 is significantly reduced due to the cleaning vibration of the extended scraper 30 and the vibrator 405. This makes the conveying amount of different materials more accurate, and different batches or types of materials can be conveyed using the same conveying unit, improving the consistency of subsequent product processing quality. At the same time, when conveying different batches or types of materials, several conveying units can be used to cooperate with several conveying through holes 101 one by one to realize the separate conveying of different batches or types of materials, further reducing the interference between different batches or types of materials and further improving processing accuracy.
