Description

Technical Field

[0001] This utility model relates to solid waste treatment equipment, specifically to a device for recovering metal materials contained in solid waste and a recycling production line equipped with the device. Background Technology

[0002] Yellow zinc ash is an important byproduct generated during the hot-dip galvanizing process. Its main components include zinc oxide (ZnO), metallic zinc particles, and various impurities. The content of metallic zinc particles is relatively high, which makes yellow zinc ash one of the core raw materials for recycled zinc.

[0003] Most impurities in zinc slag are physically loose and easily dispersed, but some impurities still tend to adhere to the surface of zinc particles, forming lumpy impurities, which affects zinc resource recovery. For example, patent application number 202323167746.5 discloses a high-efficiency zinc slag recycling and processing device, which includes a base plate. A lower housing of a crusher is mounted on the upper part of the base plate via multiple support rods. An upper housing of a crusher is connected to the upper end of the lower housing via an installation mechanism. An inclined feed box is located on one side of the upper housing, and a positioning shaft is rotatably connected to one side of the feed box. The positioning shaft has a feeding mechanism. Two drive shafts are rotatably connected inside the lower housing of the crusher. Both drive shafts have crushing rollers on their outer walls, and one end of each drive shaft extends to the outside and is equipped with a drive wheel. The two drive wheels are meshed together, and both drive shafts have a drive mechanism. In this patent, a crusher is used to crush industrial zinc slag waste to remove zinc particles and the fly ash adhering to their surface.

[0004] However, simply crushing the zinc ash is still insufficient to completely separate the detached impurities from the zinc particles. Furthermore, when faced with large lumps of impurities, including zinc particles, crushing can only break them into smaller pieces, while the zinc particles may still be trapped inside these smaller pieces. As a result, the recovery rate of zinc raw materials remains difficult to improve significantly. Utility Model Content

[0005] One of the objectives of this invention is to provide a zinc recycling device that achieves the separation of impurities from zinc particles through the cooperation of multiple components.

[0006] The second objective of this utility model is to provide a metal recycling production line equipped with the aforementioned zinc recycling equipment and possessing a high recovery rate.

[0007] This utility model is achieved through the following technical solution:

[0008] In a first aspect, this utility model provides a zinc recycling device, which has a crushing section, at least one set of separation sections and a material collection section arranged sequentially along the recycling processing path on the main frame, and the sections are connected by a first conveying kit; wherein, in the separation section, a crushing section and a screening section are arranged sequentially along the recycling processing path; the crushing section includes at least two sets of crushing rollers, and a crushing channel is formed between two adjacent sets of crushing rollers; the screening section includes a screening screen, and the receiving end of the screening screen is used to receive the material output from the crushing channel, and the position of the receiving end is higher than the discharge end of the screening screen.

[0009] As a further improvement of this utility model, in several sets of separation sections continuously arranged along the recycling and processing path, the height difference between the receiving end and the discharge end gradually increases.

[0010] As a further improvement of this utility model, the screening section also includes a vibrating section for driving the screening screen to vibrate.

[0011] As a further improvement of this utility model, the separation section also includes a guide bucket, which is located at the feed inlet of the crushing section and is used to receive and collect the material output from the upstream component.

[0012] As a further improvement of this utility model, it includes two sets of continuously arranged separation sections, with the separation section near the crushing section positioned above the other separation section, and the discharge end of the upper separation section connected to the feed inlet of the crushing section of the lower separation section.

[0013] As a further improvement of this utility model, the separating part also includes an adjusting kit, which is used to control the relative position of the rolling part in the horizontal direction.

[0014] As a further improvement of this utility model, the crushing section includes a crushing chamber and two sets of crushing rollers disposed within the crushing chamber.

[0015] As a further improvement of this utility model, the first conveying kit includes a belt conveyor connecting the crushing section and the separating section, and a guide section connecting the separating section and the material collecting section, wherein the guide section has a guide groove for accommodating and guiding the material to move.

[0016] As a further improvement of this utility model, it also includes a waste collection unit, which includes at least a collection hopper disposed below the screening screen, a waste container, and a second conveying kit connecting the collection hopper and the waste container.

[0017] Secondly, this utility model provides a metal recycling production line, which includes any of the zinc recycling devices described above.

[0018] The beneficial effects of this utility model include:

[0019] (1) The crushing section can crush large-sized block impurities to adapt to the work of the subsequent separation section, and can also achieve the initial separation between some loose impurities and zinc material; while the set of several separation sections further separates zinc material from impurities still attached to it, thereby improving the overall recovery rate of zinc material in zinc ash through the cooperation between the two sets of components.

[0020] (2) In the separation section, the lumpy impurities containing zinc are crushed and deformed by the crushing rollers. During this process, because zinc has good ductility, it can be processed into flat material after being crushed without being crushed. On the one hand, during the crushing process of the lumpy impurities, the impurities that are not easily deformed attached to the surface of the zinc are easily crushed and fall off, thus realizing the separation between the impurities and the zinc. On the other hand, the zinc material processed into flat shape is not easy to pass through the holes in the subsequent screening screen, while the loose impurities that have fallen off are easy to pass through the holes, thus further realizing the complete separation of impurities and zinc in the subsequent screening section.

[0021] (3) The overall structure of the zinc recycling equipment is relatively simple, which makes it suitable for harsh factory production environments and facilitates the promotion and use of zinc recycling equipment. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0028] Example 1:

[0029] This embodiment provides a zinc recycling device, such as... Figure 1 As shown, on the main frame A, a crushing section 1, two sets of separation sections 2 and a material collection section are arranged sequentially along the recycling and processing path, and the sections are connected to each other through the first conveying kit 3.

[0030] In this embodiment, the crushing section 1 includes a crushing chamber and two sets of crushing rollers disposed within the crushing chamber. The crushing teeth on the two sets of crushing rollers mesh with each other to crush the material passing through. The crushing rollers can be any type of crusher roller. In this embodiment, the crushing rollers include a drive roller, on which several sets of crusher blades are mounted. The crusher blades are provided with several sets of tooth blocks. The tooth blocks on the two sets of crushing rollers cooperate with each other so that the material passing through them can be crushed.

[0031] like Figures 1-2 As shown, this embodiment includes two sets of continuously arranged separation sections 2; in each set of separation sections 2, a crushing section 201 and a screening section 202 are arranged sequentially along the recycling processing path; the crushing section 201 includes two sets of crushing rollers 201-1, and a crushing channel is formed between two adjacent sets of crushing rollers 201-1. In use, both sets of crushing rollers 201-1 rotate toward the position of the crushing channel to drive the material to move toward the crushing channel and be crushed. For example, in this embodiment, the crushing channel is arranged vertically so that the material can be affected by its own gravity to generate a tendency to pass through the crushing channel, and under the drive of the crushing rollers 201-1, it will eventually be deformed and pass through the crushing channel; the screening section 202 includes a screening screen, the screening screen The receiving end 202-1 is used to receive the material output from the crushing channel. The position of the receiving end 202-1 is higher than the discharge end 202-2 of the screening screen, so that the material falling on the screening screen can move from the receiving end 202-1 to the discharge end 202-2 under the influence of gravity. The separation part 2 near the crushing part 1 is placed above another separation part 2. At the same time, the discharge end 202-2 of the upper separation part 2 is connected to the feed port of the crushing part 201 of the lower separation part 2. This allows the lower separation part 2 to crush the material a second time after receiving the material processed by the upper separation part 2, so as to remove impurities from the zinc surface again and further ensure the complete separation between impurities and zinc.

[0032] The material collection section is used to collect the separated zinc material. In this embodiment, the material collection section is a collection bag, but any other storage structure such as a collection hopper is also applicable.

[0033] like Figure 1As shown, the first conveying assembly 3 includes a belt conveyor 301 connecting the crushing section 1 and the separating section 2. In this embodiment, two sets of separating sections 2 are arranged stacked vertically. Since the crushing section 1 needs to be easily accessible for material input, a significant height difference exists between the two. In this embodiment, one end of the belt conveyor 301 is positioned lower at the discharge point of the crushing section 1, while the other end is positioned higher at the top of the upper separating section 2, to transport the pre-crushed material to the separating section 2 for separation. Simultaneously, the first conveying assembly 3 also includes a guide section 302 connecting the separating section 2 and the material collection section, such as... Figure 1 As shown, a guide groove is provided in the guide section 302 to accommodate and guide the material to move. The end of the guide groove that receives the material is higher and the end that outputs the material is lower, so that the material can slide down the inclined structure and finally be placed into the material collection section.

[0034] The operating steps of this zinc recycling equipment are as follows: First, the user adds zinc ash to the crushing section 1. During this process, the zinc ash is crushed by the crushing rollers, and large impurities are dispersed into smaller ones. During this time, some loosely attached impurities on the zinc material undergo initial detachment and separation. Then, the crushed material is conveyed to the upper separation section 2 via belt conveyor 301 for the first impurity separation. During this process, the material moves downwards due to its own gravity and the drive of the rolling rollers 201-1, passing through the rolling channel. The zinc material, a material with good ductility, is flattened by the pressure of the two sets of rolling rollers 201-1, and the remaining loose impurities are separated from the zinc material during the deformation process. The material surface detaches, and then the material falling through the crushing section 201 onto the screening screen. Small particles of impurities formed by crushing and crushing can pass through the screen holes, while zinc material, due to its flat shape, does not easily pass through the screen holes, thus achieving complete separation between impurities and zinc material. At the same time, due to the inclined setting of the screening screen, zinc material and other materials can move downward with the incline until they fall into the separation section 2 below for secondary separation, further separating the impurities that could not be peeled off in the previous step, and improving the zinc material recovery rate. Finally, the zinc material output from the separation section 2 below is received by the guide section 302 and finally guided and transported to the material collection section. In this way, the zinc material recovery equipment completes the separation and recovery of zinc material from zinc ash.

[0035] Preferably, such as Figure 1As shown, the height difference between the receiving end 202-1 and the discharge end 202-2 of the screen in the upper separation section 2 is smaller than that between the receiving end 202-1 and the discharge end 202-2 of the screen in the lower separation section 2. This is because the upper separation section 2 is mainly used for the first complete separation of impurities and zinc material, which involves a larger amount of impurities. The smaller height difference allows for a longer retention time of the material on the screen, thus achieving a more thorough separation between the large amount of impurities and zinc material.

[0036] Preferably, the screening section 202 also includes a vibrating section, which drives the screening screen to vibrate so that the material is bumped on the screening screen. Some of the impurities that were originally supported by the zinc material on the screening screen can also fall onto the screening screen and be screened after being bumped, thereby accelerating the complete separation between the impurities and the zinc material.

[0037] Preferably, such as Figure 1 As shown, the separation section 2 also includes a guide bucket 203, which is located at the feed inlet of the crushing section 201. The guide bucket 203 receives and collects the material output from the upstream components. For example, the guide bucket 203 in the upper separation section 2 can collect the material output from the belt conveyor 301, while the guide bucket 203 in the lower separation section 2 can collect the material output from the upper separation section 2. Because the impurities in the material are relatively light, material scattering easily occurs at the junctions of the components. The guide bucket 203 can collect such material to reduce material loss during transmission.

[0038] Preferably, such as Figure 1 As shown, the separation section 2 also includes an adjustment kit 204, which is used to control the relative position of the crushing section 201 in the horizontal direction. In this embodiment, the screening section 202 includes a vibrating section, so there is a lot of vibration during the overall operation of the zinc recycling equipment. If the crushing section 201 is fixed in the separation section 2 by welding to the fixed frame or other means, it is easy to cause breakage at the connection of the fixed frame and other components after long-term vibration. The adjustment kit 204 provides a buffer for the displacement generated by the vibration of the crushing section 201, and also allows the crushing section 201 to be adjusted back to its original position when it shifts due to long-term vibration, thereby ensuring the normal connection between the components in the separation section 2 during long-term use. For example, in this embodiment, the adjustment kit 204 includes guide rod kits disposed on both sides of the crushing part 201. The crushing part 201 is mounted on the main frame A by the guide rod kits, and moves away from or closer to the discharge end 202-2 in the horizontal direction by changing its relative position through the guide rods therein, so as to ensure that the material output by the discharge end 202-2 can be received.

[0039] Preferably, such as Figure 1As shown, the zinc recycling unit also includes a waste collection unit 4, which includes a collection hopper 401 located below the screening screen to collect impurities that have passed through the screening; a waste container 402 to receive the collected impurities for further processing; and a second conveying assembly connecting the collection hopper 401 and the waste container 402. In this embodiment, for example, the second conveying assembly 403 can also be a belt conveyor. With this structure, the zinc recycling equipment can uniformly collect the separated impurities, which reduces the occurrence of problems such as impurities scattering and falling into the transmission structure and other parts of the equipment during operation, thus causing equipment jamming. It also facilitates users to uniformly and harmlessly treat the collected impurities, thus taking into account the environmental friendliness of the recycling process.

[0041] In this embodiment, a metal recycling production line is provided, which includes the zinc recycling equipment in Embodiment 1. For example, the production line also includes pyrometallurgical reduction smelting equipment, etc., for further processing of the zinc material obtained by the zinc recycling equipment to obtain the required zinc resources.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
