Description

Technical Field

[0001] This utility model relates to the field of glass recycling technology, and in particular to a device for cleaning impurities from broken glass. Background Technology

[0002] With increasingly scarce resources and growing environmental awareness, glass recycling and reuse are of paramount importance. Glass recycling not only conserves natural resources and reduces energy consumption but also minimizes waste pollution, contributing positively to building a sustainable society. However, during the recycling process, iron impurities severely impact the quality and usability of the recycled glass. The presence of iron impurities leads to impure colors, reduced transparency, and even affects the physical and chemical properties of glass products, lowering mechanical strength and limiting the applications of recycled glass.

[0003] Currently, magnetic adsorption technology has become the primary method for removing ferrous metal impurities in the recycling of broken glass due to its advantages such as ease of operation and high adsorption efficiency. In practical applications, broken glass is usually transported by conveyor belts to facilitate subsequent magnetic adsorption adsorption processing. However, in existing conveyor belt processes, uneven accumulation of broken glass often occurs, with excessively thick accumulations in some areas. This causes ferrous metal impurities located in the lower layer of accumulated glass to be obscured by the upper layer, making it difficult for magnetic force to penetrate effectively, thus significantly reducing the adsorption effect. Furthermore, after traditional magnetic adsorption devices adsorb ferrous metal impurities, manual cleaning is usually required, making it difficult to achieve continuous automatic separation of ferrous metal impurities, resulting in low adsorption efficiency and affecting the continuity of the entire broken glass processing flow. To address these issues, existing technologies urgently need improvement. Utility Model Content

Addressing the problems of low removal efficiency due to excessive accumulation of broken glass on the conveyor belt and the difficulty in automatically cleaning magnetically attracted impurities in existing technologies, this solution cleverly incorporates a spreading mechanism.

Detailed Implementation

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] In the context of recycling glass, efficiently removing ferrous impurities from broken glass is crucial. Currently, magnetic adsorption technology, while widely used, still faces challenges in practical applications. Particularly during the conveyor belt transport of broken glass, uneven accumulation often occurs, leading to reduced adsorption efficiency.

[0031] To address this problem, this invention proposes a device for cleaning impurities from broken glass, aiming to overcome the limitations of existing technologies and achieve efficient, continuous, and automatic cleaning of ferrous metal impurities from broken glass. The core of this device lies in its unique structural design. Broken glass is transported via a conveyor belt 1, the spreading mechanism 3 adjusts the spreading thickness of the broken glass, and the magnetic ring 402 in the impurity removal component 4 adsorbs ferrous metal impurities. Finally, the impurities are cleaned into a collection hopper 6 by an arc-shaped scraper 405, thereby achieving effective separation of the impurities.

[0032] To better understand the technical solution of this utility model, it is necessary to explain some key terms. The conveyor belt 1 serves as a conveying mechanism, used to carry and transport the broken glass to be processed; the spreading mechanism 3 is a thickness adjustment device, its function being to control the accumulation thickness of the broken glass on the conveyor belt 1 to facilitate subsequent magnetic impurity removal; the impurity removal component 4 is the core functional component of this device, mainly composed of a magnetic ring 402, a motor 401, and an arc-shaped scraper 405, used to achieve the adsorption and separation of ferrous metal impurities; the collection hopper 6 serves as an impurity collection device, used to collect the ferrous metal impurities scraped off from the magnetic ring 402. It is understood that the broken glass impurity cleaning device of this utility model can be applied to various occasions requiring the removal of ferrous metal impurities from broken glass, such as glass recycling plants.

[0033] Specifically, such as Figures 1 to 5 The illustrated device for cleaning impurities from broken glass includes:

[0034] Conveyor belt 1 is used to transport broken glass;

[0035] The paving mechanism 3 is located above the conveyor belt 1 and includes a paving plate 301 and an electric cylinder 303 that drives the paving plate 301 to rise and fall. The paving plate 301 is used to adjust the paving thickness of the broken glass on the conveyor belt 1.

[0036] The impurity removal component 4 is located above the conveyor belt 1 and on the discharge side of the paving mechanism 3. It includes a magnetic ring 402, a motor 401 that drives the magnetic ring 402 to rotate, and an arc-shaped scraper 405 for cleaning the ferrous metal impurities adsorbed by the magnetic ring 402. The arc-shaped scraper 405 scrapes off the ferrous metal impurities adsorbed at the bottom of the magnetic ring 402. The collection hopper 6 is located below the magnetic ring 402 and is used to collect the ferrous metal impurities scraped off by the arc-shaped scraper 405.

[0037] Conveyor belt 1, as the basic conveying component of the device, can be made of various materials such as rubber belt, plastic belt, or metal belt to adapt to the conveying needs of different types and sizes of broken glass. In practical applications, the conveying speed of conveyor belt 1 can be adjusted according to the actual processing volume to ensure that the broken glass can enter the subsequent processing stages smoothly and evenly.

[0038] Compared with existing technologies, the impurity removal device for broken glass of this invention has significant advantages. Traditional magnetic impurity removal devices typically use fixed magnets, which have limited effectiveness in removing impurities from broken glass with uneven thickness, and the adsorbed impurities are not easily cleaned automatically, resulting in low removal efficiency. In contrast, this invention, by setting up a spreading mechanism 3, can effectively adjust the spreading thickness of the broken glass on the conveyor belt 1, preventing excessive accumulation of broken glass and ensuring that the magnetic ring 402 can fully adsorb ferrous metal impurities. Simultaneously, the structure of the rotating magnetic ring 402 and the arc-shaped scraper 405 enables continuous automatic cleaning of ferrous metal impurities without manual intervention, greatly improving removal efficiency and the continuity of the processing flow.

[0039] In operation, the broken glass to be impurities removed is first placed onto conveyor belt 1, which transports it to below the paving mechanism 3. The paving plate 301 is raised and lowered by an electric cylinder 303, adjusting the distance between it and the conveyor belt 1 to control the thickness of the broken glass on the conveyor belt 1 and prevent excessive accumulation. After the thickness is adjusted by the paving mechanism 3, the broken glass continues to be transported by conveyor belt 1 to below the impurity removal component 4. Motor 1 401 drives the magnetic ring 402 to rotate, magnetically attracting the broken glass on the conveyor belt 1 and adsorbing ferrous metal impurities onto it. As the magnetic ring 402 continues to rotate, the adsorbed ferrous metal impurities are carried to the position of the arc-shaped scraper 405. Motor 2 404 drives the arc-shaped scraper 405 to rotate, scraping off the ferrous metal impurities adsorbed on the magnetic ring 402 during rotation. The scraped-off ferrous metal impurities fall into the collection hopper 6 below. The collecting bucket 6 collects the scraped-off iron metal impurities.

[0040] As one embodiment of the present invention, the paving mechanism 3 may also include a vertical slide bar 302, which is disposed on both sides of the paving plate 301 and is used to guide the paving plate 301 when it is raised and lowered, so as to ensure the smooth raising and lowering of the paving plate 301 and avoid the occurrence of shaking or jamming.

[0041] In one embodiment of this utility model, the impurity removal component 4 further includes a connecting frame 403. The output shaft end of the motor 401 is connected to the connecting frame 403, and the magnet ring 402 is fixed to the bottom of the connecting frame 403. The rotation of the motor 401 drives the connecting frame 403 to rotate, which in turn drives the magnet ring 402 to rotate. The connecting frame 403 plays a connecting and power transmission role in the impurity removal component 4. It can be understood as an intermediate structural component used to connect the output shaft of the motor 401 and the magnet ring 402. Thus, when the motor 401 rotates, its rotational power is transmitted to the magnet ring 402 through the connecting frame 403, thereby driving the magnet ring 402 to rotate synchronously. As an alternative, the power transmission between the connecting frame 403 and the rotating shaft of the motor 401 can be achieved through various connection methods, such as key connection, pin connection, bolt connection, or friction connection, to meet different design requirements.

[0042] As one embodiment of this utility model, the impurity removal component 4 also includes a second motor 404, the output shaft end of the second motor 404 is fixedly connected to a connecting column 406, and an arc-shaped scraper 405 is fixed on the surface of the connecting column 406.

[0043] To achieve the rotation of the arc-shaped scraper 405, the impurity removal component 4 may further include a second motor 404 and a connecting column 406. The second motor 404, as an independent driving component, is specifically used to drive the arc-shaped scraper 405 to rotate. This is distinct from the first motor 401 that drives the magnet ring 402, achieving decoupling of the driving functions. This makes the motion control of the arc-shaped scraper 405 more flexible and precise. Thus, when the second motor 404 starts operating, its rotational power is transmitted to the connecting column 406, which then drives the arc-shaped scraper 405 to rotate, thereby achieving the function of scraping and cleaning the ferrous metal impurities adsorbed on the magnet ring 402.

[0044] As one embodiment of the present invention, the impurity removal component 4 further includes a chamfered portion 407, which is disposed on the top of the arc-shaped scraper 405, and the top surface of the chamfered portion 407 is in contact with the bottom surface of the magnetic ring 402, in order to assist the arc-shaped scraper 405 in scraping off the iron metal impurities adsorbed on the magnetic ring 402.

[0045] When the magnetic ring 402 rotates and carries the adsorbed ferrous metal impurities past the arc-shaped scraper 405, the inclined surface of the chamfered portion 407 first contacts the ferrous metal impurities. Utilizing the wedge-like effect created by its inclined angle, the ferrous metal impurities are effectively prevented from continuing to rotate with the magnetic ring 402, and guided to the working area of ​​the arc-shaped scraper 405. This assists the arc-shaped scraper 405 in more thoroughly scraping the ferrous metal impurities off the magnetic ring 402. As an improvement, the inclined angle of the chamfered portion 407 can be adjusted according to the actual characteristics of the impurities and the scraping requirements. For example, for impurities with strong adsorption or irregular shapes, the inclined angle of the chamfered portion 407 can be appropriately increased to improve the scraping effect. Therefore, by adding a chamfered portion 407 to the end of the arc-shaped scraper 405, the scraping ability of the arc-shaped scraper 405 for ferrous metal impurities can be effectively improved, allowing the impurities adsorbed on the magnetic ring 402 to be cleaned more thoroughly and cleanly, thereby further improving the impurity removal efficiency and effect of the broken glass impurity cleaning device.

[0046] As one embodiment of this utility model, it also includes side baffles 2, which are disposed on both sides of the conveyor belt 1 to prevent broken glass from falling off the conveyor belt 1, and the paving mechanism 3 is disposed on top of the two side baffles 2.

[0047] The side baffles 2 can be selected in style and material according to the characteristics of the conveyed material and the working environment. They are symmetrically installed on the supports on both sides of the conveyor belt 1 to prevent broken glass from sliding or splashing laterally during the conveyor belt 1 process. This ensures that the broken glass can be stably conveyed on the conveyor belt 1 to the subsequent processing station, reduces material loss, keeps the working environment clean, and improves the operating efficiency and reliability of the entire broken glass impurity cleaning device.

[0048] In one embodiment of this utility model, a platform 5 is also included. The conveyor belt 1, the impurity removal component 4, and the collection hopper 6 are all mounted on the platform 5. The platform 5 supports and fixes the conveyor belt 1, the impurity removal component 4, and the collection hopper 6, enabling them to form a compact and functionally coordinated whole. To facilitate the movement and handling of the device, the bottom of the platform 5 can be provided with structures such as anchor bolt holes or lifting holes to facilitate fixing the device to the ground or lifting it using lifting equipment. As an optional optimization, the surface of the platform 5 can be treated for rust prevention and corrosion resistance, such as by spraying rust-proof paint or galvanizing, to improve the service life of the platform 5 in harsh working environments.

[0049] It should be noted that the impurity removal component 4 is installed on the base 5 via the mounting bracket 408, wherein motor one 401 and motor two 404 are both fixed on the top of the mounting bracket 408.

[0050] As one embodiment of this utility model, the spreading plate 301 is an arc-shaped plate with the arc surface facing the feeding side of the conveyor belt 1, so as to facilitate spreading the broken glass to the discharge side of the conveyor belt 1. The arc-shaped plate is a plate-like structure with a curved surface. Compared with a flat plate, the arc-shaped plate can better guide and disperse the material. As an optional structural form, the curvature of the arc-shaped spreading plate 301 can be adjusted according to the actual characteristics of the broken glass and the spreading requirements. For example, for large pieces or thick piles of broken glass, an arc-shaped plate with a larger curvature can be selected to provide stronger spreading capacity.

[0051] The design of the arc-shaped spreading plate 301 can more effectively achieve uniform spreading of broken glass, making the thickness of the broken glass layer more uniform. This creates more favorable material conditions for the subsequent magnetic ring 402 to perform efficient and uniform magnetic adsorption and impurity removal, further improving the impurity removal performance of the entire impurity cleaning device.

[0052] As one embodiment of this utility model, the bottom end of the collecting hopper 6 is provided with an outlet, which is used to discharge the collected iron metal impurities, thereby realizing the automatic discharge of iron metal impurities.

[0053] To ensure the automatic discharge of ferrous metal impurities collected in the collection hopper 6 without the need for regular manual cleaning, this invention incorporates an outlet at the bottom of the collection hopper 6. In its simplest implementation, the outlet can be a simple opening at the bottom of the collection hopper 6. Utilizing gravity, the collected ferrous metal impurities will automatically exit the collection hopper 6 through this outlet and fall into a subsequent collection container or conveying device. To facilitate control over the discharge volume and timing, an optional improvement is to install a valve device at the outlet, such as a manual or electric valve. By controlling the opening and closing of the valve, the on / off state of the outlet can be adjusted, thereby controlling the impurity discharge process. For example, the valve can be set to open periodically to discharge impurities from the collection hopper 6, or a sensor can be used to detect the amount of impurities in the collection hopper 6, automatically opening the valve to discharge them when the amount reaches a certain level.

[0054] In summary, by setting an outlet at the bottom of the collection hopper 6, the collected ferrous metal impurities can be automatically discharged from the collection hopper 6 by their own gravity or the action of auxiliary devices, realizing the automated operation of impurity collection and discharge without manual intervention. This significantly reduces manual maintenance costs and improves the automation level and overall operating efficiency of the broken glass impurity cleaning device.

[0055] Working principle of this utility model:

[0056] In use, the broken glass to be cleaned is placed on one end of the conveyor belt 1 near the side baffle 2. The broken glass is conveyed by the conveyor belt 1. The spreading plate 301 is raised and lowered by the telescopic end of the electric cylinder 303. While the spreading plate 301 is raising and lowering, the vertical slide rod 302 guides it, making the spreading plate 301 rise and fall smoothly. By adjusting the height distance between the spreading plate 301 and the conveyor belt 1, the required spreading thickness of the broken glass can be adjusted according to actual needs. This prevents the broken glass on the conveyor belt 1 from being too thick, which would affect the magnetic attraction effect of the subsequent magnetic ring 402 on ferrous metals. The rotating end of the motor 401 rotates... The connecting frame 403 rotates synchronously, which in turn drives the magnetic ring 402 to rotate. At the same time, the second motor 404 rotates, which drives the connecting column 406 to rotate the arc-shaped scraper 405. The arc-shaped scraper 405 and the chamfered part 407 block the ferrous metal passing by the bottom of the magnetic ring 402. Meanwhile, the top surface of the chamfered part 407 is in contact with the bottom surface of the magnetic ring 402. The arc-shaped scraper 405 scrapes off the ferrous metal that the magnetic ring 402 has absorbed and transported into the collection hopper 6. The ferrous metal is discharged from the outlet at the bottom of the collection hopper 6 under its own gravity. In this process, the ferrous metal is continuously and automatically cleaned off the magnetic ring 402.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
