Description

Technical Field

[0001] This utility model belongs to the field of smelting technology, specifically a copper-tin heterogeneous solid waste recycling and smelting device. Background Technology

[0002] Copper and tin, as important non-ferrous metals, play an indispensable role in modern industry. Copper, due to its excellent electrical and thermal conductivity and good mechanical properties, is widely used in power, electronics, construction, and transportation fields, such as in wire and cable manufacturing, motor manufacturing, and heat exchangers. Tin, with its low melting point, good corrosion resistance, and solderability, is in high demand in electronic welding, food packaging, and alloy manufacturing, such as in the welding of electronic components and the use of tin-plated sheets for food canning. With the acceleration of global industrialization, the demand for copper and tin resources continues to rise.

[0003] Meanwhile, the patent specification with application number CN106399692B discloses an enrichment smelting method for the resource utilization of copper-containing solid waste. "Copper-containing solid waste is oxidized and converted in a lime solution by introducing oxygen. The conversion slag is mixed with other copper-containing solid waste ingredients, ensuring that the moisture, copper content, and FeO:SiO2:CaO mass ratio of the mixture are maintained within required ranges. Simultaneously, starch is added to prepare bricks. The mixed bricks and coke are alternately added to a smelting furnace, and oxygen-enriched air is introduced for enrichment smelting. The heavy phase melt produced by smelting is separated into crude copper and matte by a controlled cooling system. The smelting slag is then depleted and fumed in a fumigation furnace to recover copper and tin respectively. The smelting slag is further ground and then beneficiated to further recover copper. The core of this invention is firstly, calcium sulfate as a novel sulfur-fixing agent; secondly, starch is used as both a binder and a reducing agent; thirdly, the copper content in the smelting slag is controlled to achieve the harmless and resource-based utilization of copper-containing solid waste; and finally, the depletion and fuming processes are used to recover copper and tin from the smelting slag."

[0004] In the operation of existing copper-tin heterogeneous solid waste recycling and smelting equipment, most of the crushing components have simple structures, which makes it difficult to effectively crush the tough or large lumps that may exist in the copper-tin solid waste. As a result, a large amount of waste cannot meet the ideal particle size requirements before smelting, which seriously affects smelting efficiency and quality. Secondly, most of the existing crushing mechanisms are designed in a fixed manner, which cannot flexibly adjust the crushing force and range. This results in the output copper-tin lumpy waste having a uniform size, which is difficult to adapt to the complex and ever-changing industrial production requirements.

[0005] Therefore, a copper-tin heterogeneous solid waste recycling and smelting device is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a copper-tin heterogeneous solid waste recycling and smelting device, which has the advantages of providing a high-quality raw material base for subsequent smelting processes, significantly improving the efficiency and quality of the entire recycling and smelting process, and making the produced copper-tin block waste more diverse in size, thus better adapting to complex and ever-changing industrial production requirements.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a copper-tin heterogeneous solid waste recycling and smelting device, comprising a support box, a power motor fixedly connected to one end of the support box, a rotating shaft fixedly connected to the output end of the power motor, a support frame fixedly connected to the inner surface of the support box, a protective sleeve fixedly connected to the top end of the support frame, a bevel gear fixedly connected to one end of the rotating shaft through the protective sleeve, a bevel gear two meshing with the outer surface of the bevel gear one, a rotating shaft two fixedly sleeved on the inner surface of the bevel gear two, a rotating shaft two rotatably connected to the bottom end of the rotating shaft two, a crushing head fixedly connected to the top end of the rotating shaft two, and the rotating shaft two connected to the bottom of the crushing head at an off-center position, and an auxiliary crushing component installed on the inner surface of the support box.

[0008] Preferably, the outer surface of the rotating shaft is provided with a protective sleeve 2, one end of the protective sleeve 2 is fixedly connected to the protective sleeve 1, and the other end of the protective sleeve 2 is fixedly connected to the inner wall of one side of the support box.

[0009] Preferably, a hopper is fixedly connected to the bottom end of the support box.

[0010] Preferably, the crushing head has a frustum-shaped structure, and the outer surface of the crushing head is equipped with spiral crushing teeth.

[0011] Preferably, the auxiliary crushing component includes two cylinders, which are fixedly connected to both ends of the support box, and the output ends of the two cylinders are fixedly connected to a crushing cylinder. The crushing cylinder is slidably connected to the support box, the crushing head is located inside the crushing cylinder, and a plurality of crushing teeth arranged in a ring array are fixedly connected to the inner surface of the crushing cylinder.

[0012] Preferably, four guide blocks are fixedly connected to the bottom end of the crushing cylinder, and the inner surface of the support box is provided with guide grooves for the four guide blocks.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting up a power motor, the crushing head is driven by the power motor to make circular motion around the rotating shaft.

[0024] 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.

[0025] like Figures 1 to 4As shown, this utility model provides a copper-tin heterogeneous solid waste recycling and smelting device, including a support box 1. A power motor 2 is fixedly connected to one end of the support box 1. A rotating shaft 28 is fixedly connected to the output end of the power motor 2. A support frame 22 is fixedly connected to the inner surface of the support box 1. A protective sleeve 23 is fixedly connected to the top of the support frame 22. One end of the rotating shaft 28 passes through the protective sleeve 23 and is fixedly connected to a bevel gear 29. A bevel gear 26 is meshed with the outer surface of the bevel gear 29. A rotating shaft 27 is fixedly sleeved on the inner surface of the bevel gear 26. The bottom end of the rotating shaft 27 is rotatably connected to the support frame 22. A crushing head 24 is fixedly connected to the top of the rotating shaft 27. The rotating shaft 27 is connected to the bottom of the crushing head 24 at an off-center position. The power motor 2 drives the bevel gear transmission to drive the crushing head 24 to rotate. The eccentric connection at the bottom of the crushing head 24 can more fully crush the copper-tin heterogeneous solid waste and improve the crushing effect. An auxiliary crushing component 4 is installed on the inner surface of the support box 1.

[0026] Specifically, the outer surface of the rotating shaft 28 is provided with a protective sleeve 21, one end of which is fixedly connected to the protective sleeve 23, and the other end of which is fixedly connected to the inner wall of the support box 1. The protective sleeve 21 can protect the rotating shaft 28, prevent waste from causing wear and corrosion to the rotating shaft 28, extend the service life of the rotating shaft 28, and also prevent waste from entering the transmission structure and affecting the normal operation of the device.

[0027] like Figures 1 to 4 As shown, a feeding hopper 3 is fixedly connected to the bottom of the support box 1. The feeding hopper 3 facilitates the smooth discharge of the crushed copper-tin heterogeneous solid waste from the device, which is convenient for subsequent collection and processing and improves the continuity of the entire recycling and smelting process.

[0028] Furthermore, the crushing head 24 has a truncated cone shape, and the outer surface of the crushing head 24 is equipped with spiral crushing teeth 25. The design of the truncated cone shape and the spiral crushing teeth 25 can increase the contact area and friction between the crushing head 24 and the waste, making the crushing process more efficient and able to effectively crush waste of different sizes.

[0029] like Figures 1 to 4As shown, the auxiliary crushing component 4 includes two cylinders 43, which are fixedly connected to both ends of the support box 1. The output ends of the two cylinders 43 are fixedly connected to a crushing cylinder 41. The crushing cylinder 41 is slidably connected to the support box 1. The crushing head 24 is located inside the crushing cylinder 41. Several crushing teeth 44 arranged in a ring array are fixedly connected to the inner surface of the crushing cylinder 41. Under the action of the two cylinders 43, the position of the crushing cylinder 41 can be flexibly adjusted, and the relative position and range of action between the crushing cylinder 41 and the crushing head 24 can be changed, thereby realizing the flexible adjustment of the crushing force and range, making the produced copper-tin block waste more diverse in size, and better adapting to the complex and ever-changing industrial production requirements.

[0030] It is worth noting that four guide blocks 42 are fixedly connected to the bottom of the crushing cylinder 41, and four guide grooves 30 for the guide blocks 42 are opened on the inner surface of the support box 1. The cooperation between the guide blocks 42 and the guide grooves 30 can ensure the stability and accuracy of the crushing cylinder 41 during the sliding process, making the cooperation between the crushing cylinder 41 and the crushing head 24 more precise and improving the crushing effect.

[0031] The power motor 2 is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0032] Working principle and process: When using this copper-tin heterogeneous solid waste recycling and smelting device, firstly, pour the copper-tin heterogeneous solid waste into the crushing drum 41, start the power motor 2, and the power motor 2 drives the rotating shaft 28 to rotate. Since the bevel gear 29 on the rotating shaft 28 meshes with the bevel gear 26, the bevel gear 26 will drive the rotating shaft 27 to rotate, thereby causing the crushing head 24 connected to the top of the rotating shaft 27 to rotate. Because the rotating shaft 27 is connected to the bottom of the crushing head 24 at an off-center position, the crushing head 24 will make a circular motion around the center of the rotating shaft 27. When it is necessary to adjust the size of the waste, start the auxiliary crushing component 4. Two cylinders 43 are used. The output end of the cylinders 43 pushes the crushing cylinder 41 to slide inside the support box 1. The guide block 42 at the bottom of the crushing cylinder 41 slides in the guide groove 30 to ensure the stability of the crushing cylinder 41. This allows the crushing teeth 44 on the crushing cylinder 41 to gradually move away from the spiral crushing teeth 25 on the outer surface of the crushing head 24. When the appropriate angle is reached, the cylinders 43 can be turned off. Then, under the action of the crushing teeth 25 and the crushing teeth 44, the copper-tin heterogeneous solid waste in the crushing cylinder 41 can be crushed. The crushed copper-tin heterogeneous solid waste is discharged from the feed hopper 3 at the bottom of the support box 1 for subsequent recycling and smelting.
