Description

Technical Field

[0001] This utility model relates to the field of roasting furnace technology, and in particular to an automatic feeder for a zinc oxide production and smelting roasting furnace. Background Technology

[0002] In the zinc oxide production and smelting process, the roasting furnace is the core equipment for roasting raw materials such as zinc concentrate to produce zinc oxide calcined sand. The stability and accuracy of the feeding process directly affect the roasting reaction efficiency, product quality and energy consumption control.

[0003] Currently, some small and medium-sized smelting enterprises still rely on manual labor to feed raw materials such as zinc concentrate and recycled materials into the roasting furnace through hoppers or conveyor belts. This method is greatly affected by the intensity, skill and sense of responsibility of manual operation, and is prone to problems such as inconsistent feeding amount and uneven feeding interval, resulting in uneven distribution of raw materials in the roasting furnace and large fluctuations in reaction temperature. This not only reduces the zinc oxide conversion rate, but may also generate impurities due to local overheating, thereby affecting the purity of the product.

[0004] Therefore, an automatic feeder for zinc oxide production smelting roasting furnace is proposed. Utility Model Content

This solves the problem that some small and medium-sized smelting enterprises still rely on manual labor to feed raw materials such as zinc concentrate and recycled materials into the roasting furnace through hoppers or conveyor belts. This method is greatly affected by the intensity, skill, and sense of responsibility of manual operation, and is prone to problems such as inconsistent feeding amounts and uneven feeding intervals. This results in uneven distribution of raw materials in the roasting furnace and large fluctuations in reaction temperature, which not only reduces the conversion rate of zinc oxide, but may also generate impurities due to local overheating, thus affecting the purity of the product.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] An automatic feeder for a zinc oxide production smelting roasting furnace includes a base 1, a roasting furnace body 2 fixedly connected to the top of the base 1, a metering component 3 above the roasting furnace body 2, a feeding component 4 inside the metering component 3, the metering component 3 including a fixed cylinder 31, a metering cylinder 32 inside the fixed cylinder 31, vertical mounting holes 33 on both sides of the inner wall of the fixed cylinder 31, limit blocks 34 fixedly connected to both sides of the surface of the metering cylinder 32, and the limit blocks 34 are located inside the vertical mounting holes, a weight sensor 35 fixedly installed at the bottom of the inner wall of the vertical mounting holes 33, the limit blocks 34 are located on top of the weight sensor 35 and the limit blocks 34 cooperate with the weight sensor 35.

[0026] In this embodiment: by setting the metering component 3, the fixed cylinder 31 can provide installation space and positioning reference for the internal components, while protecting the metering cylinder 32 and avoiding interference from the external environment on the metering process. The mounting vertical holes 33 on the inner wall of the fixed cylinder 31 can provide a stable installation position for the limiting block 34 and the weight sensor 35, ensuring the overall stability of the metering component 3. The metering cylinder 32 is a container that directly carries the material and is used to temporarily store the material to be sent into the roasting furnace, ensuring that the material can be stably stacked, providing a basis for the accurate detection of the weight sensor 35. The mounting vertical holes 33 are the accommodating space for the limiting block 34 and the mounting space for the weight sensor 35. By limiting the movement range of the limiting block 34, the carrier can indirectly play a longitudinal positioning role for the metering cylinder 32, preventing the metering cylinder 32 from shifting during material loading or unloading, and ensuring the accuracy of weight detection. On the one hand, the limiting block 34 can limit the horizontal swaying of the metering cylinder 32 and ensure its stable placement. On the other hand, the limiting block 34 can directly press on the top of the weight sensor 35, transmitting the weight of the metering cylinder 32 and the material inside to the weight sensor 35, so that the weight sensor 35 can sense the pressure transmitted by the limiting block 34 in real time, realizing accurate monitoring and control of the material weight, thereby achieving the metering effect of the material.

[0027] Specifically, such as Figure 3 , Figure 4 As shown, the feeding assembly 4 includes an adjusting plate 41, and a base plate 42 is fixedly connected to the bottom of the inner wall of the metering cylinder 32. The adjusting plate 41 is set on the top of the base plate 42, and the adjusting plate 41 and the base plate 42 are in close contact with each other.

[0028] Specifically, such as Figure 3 , Figure 4 As shown, the surfaces of the adjusting plate 41 and the base plate 42 are provided with a number of holes 43, and the holes 43 correspond one-to-one.

[0029] Specifically, such as Figure 3 , Figure 4 As shown, a servo motor 44 is fixedly installed in the middle of the bottom of the base plate 42. The output shaft of the servo motor 44 passes through the base plate 42 and is fixedly connected to the adjustment plate 41.

[0030] In this embodiment: by setting the feeding component 4, the adjusting plate 41 can be tightly fitted with the base plate 42 to form a sealing mating surface. The leakage holes 43 on the surface of the adjusting plate 41 can be rotated to overlap with the leakage holes 43 on the base plate 42 to different degrees, thereby precisely controlling the size of the material falling channel. The base plate 42, as the fixed base of the feeding component 4, can provide stable support and a mating surface for the adjusting plate 41. The leakage holes 43 on its surface match the leakage holes 43 on the adjusting plate 41 to form a material falling channel. The leakage holes 43 are the material falling channel. When the adjusting plate 41 rotates... When the upper and lower holes 43 are aligned, the material in the metering cylinder 32 can enter the interior of the roasting furnace body 2 through the holes 43. By controlling the overlapping area of ​​the holes 43, the feeding rate can be flexibly adjusted to meet the feeding requirements of different roasting stages. The servo motor 44 is fixedly connected to the adjustment plate 41 through the output shaft, which can accurately control the rotation angle and speed of the adjustment plate 41. The servo motor 44 can drive the adjustment plate 41 to quickly switch to the preset position to achieve precise alignment of the holes 43, thereby completing the start, stop or speed adjustment of feeding, and ensuring the automation and controllability of the feeding process.

[0031] Specifically, such as Figure 1 As shown, a support column 5 is fixedly connected to the top of the base 1, and a screw conveyor 6 is fixedly installed on the top of the support column 5. The fixed cylinder 31 is fixedly connected to the bottom of the discharge end of the screw conveyor 6.

[0032] Specifically, such as Figure 5 As shown, a storage hopper 7 is fixedly connected to the top of the feed end of the screw conveyor 6. A top cover 8 is fixedly connected to the top of the storage hopper 7, and a feed pipe 9 is fixedly connected to the top of the top cover 8. A drive motor 10 is fixedly installed on the top of the top cover 8. The output end of the drive motor 10 passes through the top cover 8 and is fixedly connected to a rotating shaft 11. Multiple crushing blades 12 are fixedly connected to the surface of the rotating shaft 11.

[0033] In this embodiment: Through the above settings, the support column 5 can ensure that the screw conveyor 6 operates stably at a suitable height, ensuring that materials can be smoothly conveyed from the storage hopper 7 to the metering component 3. The screw conveyor 6 is the core equipment for material conveying. Its feed end can receive materials from the storage hopper 7. Through the rotation of the internal spiral blades, the materials are continuously and stably pushed along the pipe of the screw conveyor 6 to the discharge end, and finally conveyed to the fixed cylinder 31 below, realizing the automated transfer of materials from the storage stage to the metering stage, avoiding manual handling, and improving conveying efficiency. The storage hopper 7 is a temporary storage container for materials. It can store a certain amount of raw materials to ensure the continuity of subsequent conveying links. The top cover 8 can play a sealing role to prevent external dust and impurities from entering the storage hopper 7 and contaminating the raw materials. The drive motor 10 can drive the rotating shaft 11 to rotate through the output end. The rotating shaft 11 serves as the mounting carrier for the crusher 12 and can transmit the power of the drive motor 10 to the crusher 12, thereby driving the crusher 12 to rotate synchronously. This can crush the raw materials that may clump in the storage hopper 7, break up large clumps, and prevent clumps from clogging the screw conveyor 6 or affecting the metering accuracy, thus meeting the feeding requirements of the roasting furnace body 2 for raw materials.

[0034] Specifically, such as Figure 4 As shown, a conical cover 13 is fixedly connected to the bottom of the base plate 42, and the servo motor 44 is located inside the conical cover 13.

[0035] Specifically, such as Figure 1 As shown, a PLC controller 14 is fixedly mounted on the surface of the support column 5. The weight sensor 35, servo motor 44 and drive motor 10 are all electrically connected to the PLC controller 14.

[0036] In this embodiment: Through the above settings, the conical cover 13 can completely protect the servo motor 44 inside, preventing the material falling from the metering cylinder 32 during the feeding process from directly contacting the servo motor 44, preventing material accumulation and dust adhesion that could cause servo motor 44 failure, thereby extending the service life of the servo motor 44. In addition, its conical structure can guide the material falling from the hole 43 to converge towards the center and enter the roasting furnace body 2, preventing the material from scattering or accumulating on the surface of the drive motor 10 during the falling process, ensuring the smoothness of the feeding path. The PLC controller 14 is the control center of the entire feeder. By receiving the material weight signal transmitted by the weight sensor 35, it can accurately determine whether the material in the metering cylinder 32 has reached the preset value, and automatically send start / stop or speed adjustment commands to the screw conveyor 6, servo motor 44 and drive motor 10. The operator can preset parameters such as feeding amount, feeding speed and crushing frequency through the PLC controller 14, thereby adapting to different roasting process requirements and improving the flexibility and applicability of the equipment.

[0037] Working principle: First, the operator presets the feeding parameters through the PLC controller 14 and adds the raw materials such as zinc concentrate to be processed into the storage hopper 7, then closes the top cover 8 to ensure a seal. Next, the PLC controller 14 starts the drive motor 10, which in turn drives the rotating shaft 11 and the crusher 12 to rotate at high speed. The crusher 12 crushes any potentially agglomerated raw materials in the storage hopper 7, ensuring uniform particle size and preventing blockages in subsequent conveying stages. The crushed raw materials then enter the screw conveyor 6 through the storage hopper 7. The PLC controller 14 then controls the screw conveyor 6 to start. The rotation of the screw blades inside the screw conveyor 6 stably transports the raw materials to the discharge end, where they finally fall into the lower connected fixed cylinder 31 and enter the metering cylinder 32. The limit blocks 34 on both sides of the metering cylinder 32 transmit the weight of themselves and the materials inside to the weight sensor 3. 5. The weight sensor 35 can detect and send the weight signal to the PLC controller 14 in real time. When the material weight reaches the preset value, the PLC controller 14 will immediately control the screw conveyor 6 to stop feeding, thus completing a single metering. After metering, the PLC controller 14 will start the servo motor 44. The output shaft of the servo motor 44 will drive the adjusting plate 41 to rotate, so that the adjusting plate 41 and the leakage hole 43 on the surface of the bottom plate 42 will gradually align. Then the material in the metering cylinder 32 will fall through the aligned leakage hole 43, and after being guided by the conical cover 13, it will accurately enter the interior of the roasting furnace body 2 below. After the feeding is completed, the servo motor 44 will drive the adjusting plate 41 to reset, so that the leakage hole 43 will be completely misaligned and sealed. Then the PLC controller 14 will start the screw conveyor 6 again for the next round of feeding and metering. This cycle can realize continuous automatic feeding.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
