Description

Technical Field

[0001] This utility model belongs to the field of glass production equipment, and particularly relates to sorting devices and float glass production equipment. Background Technology

[0002] Float glass, also known as flat glass produced using the float process, is a high-quality glass manufactured through a special process. In float glass production, cullet, as a recyclable material, is added to the raw materials to replace some of the new raw materials. In some glass production formulas, the amount of cullet added can reach about 20% to 30%, thus reducing the amount of new raw materials used and lowering production costs. However, during the transportation of cullet, impurities such as metals can easily get mixed in. If cullet contains metallic impurities, the increased iron content leads to a higher coefficient of thermal expansion in the glass. A higher coefficient of thermal expansion makes the glass more prone to cracking and even breakage, reducing its thermal stability and lifespan. Therefore, it is essential to install sorting devices to remove impurities.

[0003] The existing sorting device sorts metal from broken glass by first detecting whether there are small metal particles in the broken glass. If small metal particles are detected, the broken glass containing metal is discharged to the broken glass stockpile. After the machine stops, the metal is picked out manually from the broken glass in the stockpile. However, since a large amount of broken glass may accumulate after metal detection every day, and the accumulation area of ​​broken glass is large, it is not conducive to manual picking, resulting in low efficiency and poor removal effect of metal impurities. Utility Model Content

[0004] The purpose of this application is to provide a sorting device and float glass production equipment, which aims to solve the problem of how to improve the impurity removal rate and impurity separation efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a sorting device is provided for removing impurities from materials. The sorting device includes a first conveying structure for conveying the materials along a preset direction, a first adsorption structure for adsorbing and separating the impurities from the materials, a sensing structure for detecting whether the impurities exist in the materials, and a control structure communicatively connected to the first conveying structure and the sensing structure. The first adsorption structure and the sensing structure are sequentially disposed on the conveying path of the materials. When the sensing structure detects the presence of the impurities in the materials, the sensing structure generates a sensing signal. The control structure controls the first conveying structure to stop operating according to the sensing signal, so that the materials remain on the first conveying structure.

[0007] In some embodiments, the first adsorption structure is used to adsorb and separate impurities with a particle size greater than or equal to a preset size, and the sensing structure is used to detect impurities with a particle size smaller than the preset size.

[0008] In some embodiments, the first adsorption structure is an iron remover for adsorbing ferromagnetic impurities, and the sensing structure is a metal detector for detecting metallic impurities.

[0009] In some embodiments, the sorting device further includes a frame for supporting the first conveying structure, the first adsorption structure and the induction structure being connected to the frame, the first conveying structure having a conveying surface for carrying the material, and the first adsorption structure being located above the conveying surface.

[0010] In some embodiments, the sorting device further includes a feeding structure for feeding the material onto the first conveying structure, the first conveying structure having a feeding end that docks with the feeding structure, and the first adsorption structure being disposed at the feeding end.

[0011] In some embodiments, the first conveying structure includes a drive pulley, a driver for driving the drive pulley to rotate, and a conveyor belt wound around the drive pulley. The conveyor belt includes a conveying section extending along the preset direction, the conveying section being used to carry the material.

[0012] In some embodiments, the sorting device further includes a second conveying structure and a second adsorption structure. The second conveying structure is used to receive the material at the first conveying structure and convey the material. The second adsorption structure is disposed on the conveying path of the second conveying structure and is used to adsorb and separate the impurities from the material conveyed by the second conveying structure.

[0013] In some embodiments, the sorting device further includes a detection structure disposed on the conveying path of the second conveying structure and a material distribution structure connected to the unloading end of the second conveying structure. The detection structure is used to detect the purity of the material conveyed by the second conveying structure. The sorting device further includes a first unloading line and a second unloading line spaced apart from the first unloading line. The material distribution structure is used to transfer the detected material from the second conveying structure to the first unloading line or the second unloading line. One of the first unloading line and the second unloading line is used to receive the material that has passed the detection, and the other of the first unloading line and the second unloading line is used to receive the material that has failed the detection.

[0014] In some embodiments, the sorting device further includes a receiving structure disposed between the first conveying structure and the second conveying structure. The receiving structure is used to receive the material conveyed by the first conveying structure and to load the material from the first conveying structure onto the second conveying structure.

[0015] Secondly, a float glass production equipment is provided, which includes the sorting device described above.

[0016] The beneficial effects of this application are as follows: When the sorting device of this application is in use, the first adsorption structure can adsorb most of the impurities in the material, and the sensing structure can detect whether there are impurities in the material that have not been adsorbed by the adsorbed material. When the sensing structure detects impurities, the control structure controls the first conveying structure to stop operating, which facilitates the subsequent further sorting of impurities, thereby effectively improving the impurity removal rate. Furthermore, through the cooperation of the sensing structure and the control structure, the material with impurities can be kept on the first conveying structure, which facilitates the subsequent operators to quickly locate and sort based on this clearly defined area, thereby reducing the sorting range and improving the impurity separation efficiency.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0028] Please see Figures 1 to 4 This application provides a sorting device for removing impurities from materials. The sorting device includes a first conveying structure 10 for conveying materials along a preset direction a, a first adsorption structure 20 for adsorbing and separating impurities from the materials, a sensing structure 30 for detecting whether impurities exist in the materials, and a control structure 40 communicatively connected to the first conveying structure 10 and the sensing structure 30. The first adsorption structure 20 and the sensing structure 30 are sequentially arranged on the material conveying path. When the sensing structure 30 detects the presence of impurities in the materials, the sensing structure 30 generates a sensing signal. The control structure 40 controls the first conveying structure 10 to stop operating according to the sensing signal, so that the materials remain on the first conveying structure 10.

[0029] Understandably, the material in this embodiment is broken glass, and when the broken glass accumulates in the first conveying structure 10, it has a certain coverage area. The impurities are specifically metallic impurities. The presence of metallic impurities in the glass raw material increases the coefficient of thermal expansion of the glass. Due to the high coefficient of thermal expansion, cracks and even breakage are more likely to occur, reducing the thermal stability and service life of the glass. Of course, in other possible implementations, the material can also be other raw materials that require impurity removal for purification. This embodiment does not impose a unique limitation on the specific structure of the material.

[0030] Furthermore, the first adsorption structure 20 and the sensing structure 30 are sequentially arranged on the material conveying path. That is, during the material's forward conveying process, the material first passes through the first adsorption structure 20, which adsorbs impurities in the material. Then, the material passes through the sensing structure 30, which detects whether there are any impurities in the material that were not adsorbed by the first adsorption structure 20. It should be noted that when the first adsorption structure 20 adsorbs and separates impurities from the material, it does not adsorb the material itself.

[0031] When the sorting device of this application is in use, the first adsorption structure 20 can adsorb most of the impurities in the material, and the sensing structure 30 can detect whether there are impurities in the material that have not been adsorbed by the adsorbed material. When the sensing structure 30 detects impurities, the control structure 40 controls the first conveying structure 10 to stop operating, which facilitates the subsequent further sorting of impurities, thereby effectively improving the impurity removal rate. Furthermore, through the cooperation of the sensing structure 30 and the control structure 40, the material with impurities can be kept on the first conveying structure 10, which facilitates the subsequent operation of the operator to quickly locate and sort based on the clearly defined area, thereby reducing the sorting range and improving the impurity separation efficiency.

[0032] Understandably, when the sensing structure 30 detects impurities, the control structure 40 immediately controls the first conveying structure 10 to stop operating. At this time, the material with impurities remains within the detection range of the sensing structure 30, thereby further reducing the sorting range and further improving the impurity separation efficiency.

[0033] In some embodiments, the first adsorption structure 20 is used to adsorb and separate impurities with a particle size greater than or equal to a preset size, and the sensing structure 30 is used to detect impurities with a particle size smaller than the preset size. Specifically, the preset size can be 5 mm, but it can also be other values, which can be set according to actual needs. That is to say, the first adsorption structure 20 is used to adsorb and separate large particles of impurities, and the sensing structure 30 is used to detect small particles of impurities. The first adsorption structure 20 and the sensing structure 30 are arranged in stages along the conveying direction to form a gradient processing logic of large to small particles and magnetic separation to detection. This avoids large metal impurities from interfering with the detector accuracy and ensures that small metal residues are effectively identified, thereby further improving the impurity removal rate.

[0034] In some embodiments, the first adsorption structure 20 is a magnetic separator for adsorbing ferromagnetic impurities, and the induction structure 30 is a metal detector for detecting metallic impurities. A magnetic separator is an industrial device that uses magnetic principles to remove ferromagnetic impurities from materials. By generating a strong magnetic field, the magnetic separator adsorbs or separates ferromagnetic substances mixed in the material, greatly improving the impurity removal efficiency. Magnetic separators are stable and reliable in operation, simple and easy to install and maintain, and do not produce sparks or toxic gases when processing materials, thus avoiding fire and poisoning accidents and improving safety and environmental protection.

[0035] Optionally, the first adsorption structure 20 can be a permanent magnet separator or an electromagnetic separator. The permanent magnet separator uses permanent magnet materials (such as neodymium iron boron), requires no external power, is simple to maintain, and is suitable for continuous operation. The electromagnetic separator generates a magnetic field through an energized coil, and the magnetic force is adjustable, making it suitable for high-precision or high-volume processing scenarios.

[0036] In some embodiments, the sorting device further includes a frame 50 for supporting the first conveying structure 10. The first adsorption structure 20 and the sensing structure 30 are both connected to the frame 50. The first conveying structure 10 has a conveying surface 14 for carrying materials, and the first adsorption structure 20 is located above the conveying surface 14. The frame 50 provides rigid support for the conveyor belt, the first adsorption structure 20, and the sensing structure 30, ensuring that each component maintains a stable relative position during high-speed operation or load changes, avoiding detection errors or magnetic field deviations caused by mechanical vibration. Furthermore, the frame 50 has preset mounting interfaces, allowing for rapid and accurate adjustment of key parameters such as the installation height of the first adsorption structure 20 and the detection angle of the sensing structure 30 to meet different operating conditions. Optionally, the first adsorption structure 20 can be suspended above the conveying surface 14.

[0037] In addition, by placing the first adsorption structure 20 above the conveying surface 14, the coverage of the magnetic field of the first adsorption structure 20 can be expanded, effectively eliminating edge blind spots and improving the impurity removal rate. Furthermore, by setting the first adsorption structure 20 at a certain height above the conveying surface 14, it can effectively prevent operators from contacting the moving conveying structure, thereby improving safety.

[0038] In some embodiments, the sorting device further includes a feeding structure 61 for feeding materials to a first conveying structure 10. The first conveying structure 10 has a feeding end that docks with the feeding structure 61, and a first adsorption structure 20 is disposed at the feeding end. The feeding structure 61 feeds materials to the first conveying structure 10. The feeding end of the first conveying structure 10 receives the materials from the feeding structure 61 and drives the materials forward. The first adsorption structure 20 is disposed at the feeding end to separate large metal impurities, such as nails, screws, and metal fragments, in the initial stage when the materials enter the first conveying structure 10, preventing them from entering the later stages of the first conveying structure 10 and causing mechanical damage to the equipment and the sensing structure 30. The materials at the feeding end are loosely piled and not dispersed, allowing the first adsorption structure 20 to make full use of the initial distribution state of the materials and efficiently adsorb and separate the metal impurities before they are buried by material debris. In addition, the initial flow rate of the materials is low, giving the first adsorption structure 20 a longer working time to apply magnetic force, ensuring the effective capture of weakly magnetic metal impurities.

[0039] In some embodiments, the magnetic field strength of the first adsorption structure 20 can decrease in a gradient, that is, a high-intensity magnetic field region is formed at the feeding end of the first conveying structure 10 to adsorb large-mass metal impurities. The magnetic field strength of the first adsorption structure 20 gradually decreases along a preset direction a, thereby achieving selective adsorption of metal impurities of different particle sizes, thereby effectively improving the separation efficiency of magnetic metal impurities and reducing the false adsorption rate of non-target materials.

[0040] In some embodiments, the sorting device further includes a hopper 62 for storing materials. A feeding structure 61 can connect to the discharge port at the bottom of the hopper 62 to receive the materials flowing out of the discharge port of the hopper 62 and transfer the materials to the feeding end of the first conveying structure 10. Alternatively, materials can be shoveled into the hopper 62 by a forklift.

[0041] In some embodiments, such as Figure 2 As shown, the first conveying structure 10 includes a drive pulley 11, a driver 12 for driving the drive pulley 11 to rotate, and a conveyor belt 13 wound around the drive pulley 11. The conveyor belt 13 includes a conveying section extending along a preset direction a, which is used to carry materials. By setting the conveyor belt 13, frictional noise is significantly reduced during the conveying process, and the surface of the conveyor belt 13 is flat and the operation is stable, so that the material is evenly spread, avoiding accumulation or local idling, and maximizing the adsorption efficiency of the first adsorption structure 20 and the detection efficiency of the sensing structure 30.

[0042] In some embodiments, such as Figure 1 As shown, the control structure 40 is equipped with a start button 41 and a stop button 42. Pressing the stop button 42 can control the first conveying structure 10 to stop operating, and pressing the start button 41 can control the first conveying structure 10 to start.

[0043] In some embodiments, such as Figure 3 and Figure 4 As shown, the sorting device also includes a second conveying structure 71 and a second adsorption structure 72. The second conveying structure 71 receives and conveys the material from the first conveying structure 10. The second adsorption structure 72 is located on the conveying path of the second conveying structure 71 and is used to adsorb and separate impurities from the material conveyed by the second conveying structure 71. By setting the first conveying structure 10 and the second conveying structure 71 to convey materials sequentially, and by setting the first adsorption structure 20 and the second adsorption structure 72 on the first conveying structure 10 and the second conveying structure 71 respectively to adsorb and separate impurities sequentially, multiple adsorptions can further improve the impurity removal rate and reduce the number of times the material is returned at the end of the second conveying structure 71, greatly improving the transportation efficiency of the second conveying structure 71. In addition, the first conveying structure 10 and the first adsorption structure 20 remove most metal impurities, significantly reducing the processing load of the second conveying structure 71 and the second adsorption structure, which is beneficial to extending the service life of the core components.

[0044] In some embodiments, such as Figure 4As shown, the sorting device also includes a detection structure 73 located on the conveying path of the second conveying structure 71 and a material separating structure 74 connected to the unloading end of the second conveying structure 71. The detection structure 73 is used to detect the purity of the material conveyed by the second conveying structure 71. The sorting device also includes a first unloading line and a second unloading line 76 spaced apart from the first unloading line. The material separating structure 74 is used to transfer the detected material from the second conveying structure 71 to either the first unloading line or the second unloading line 76. One of the first unloading line and the second unloading line 76 is used to receive the qualified material, and the other of the first unloading line and the second unloading line 76 is used to receive the unqualified material. It can be understood that the detection structure 73 is used to detect the purity of the material conveyed by the second conveying structure 71, that is, to detect whether there are still impurities in the material conveyed by the second conveying structure 71.

[0045] After the material is detected by the detection structure 73, the material can be transferred to either the first feeding line 76 or the second feeding line 76 via the material distribution structure 74. The first feeding line receives qualified materials, and the second feeding line 76 receives unqualified materials, or vice versa. Thus, the sorting device of this application can automatically transfer qualified and unqualified materials to different locations to facilitate subsequent material processing, thereby improving productivity and the convenience of material loading. Specifically, when the first feeding line receives unqualified materials and the second feeding line 76 receives qualified materials, the first feeding line can recycle the materials to re-adsorb impurities, while the second feeding line 76 can convey the materials to the next process. Optionally, the material distribution structure 74 can be a material distributor, etc.

[0046] In some embodiments, the sorting device further includes a receiving structure 77, which is disposed between the first conveying structure 10 and the second conveying structure 71. The receiving structure 77 is used to receive the material conveyed by the first conveying structure 10 and to load the material from the first conveying structure 10 onto the second conveying structure 71. By providing the receiving structure 77, a connecting function is provided between the first conveying structure 10 and the second conveying structure 71, improving the smoothness of material transfer.

[0047] This utility model also proposes a float glass production equipment, which includes a sorting device. The specific structure of the sorting device is as described in the above embodiments. Since this float glass production equipment adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0048] In summary, when the sorting device of this application is in use, the first adsorption structure 20 can adsorb most of the impurities in the material, and the sensing structure 30 can detect whether there are impurities in the material that have not been adsorbed. When the sensing structure 30 detects impurities, the control structure 40 controls the first conveying structure 10 to stop operating, which facilitates further sorting of impurities and thus effectively improves the impurity removal rate. Furthermore, through the cooperation of the sensing structure 30 and the control structure 40, the material with impurities can be kept on the first conveying structure 10, which facilitates subsequent operators to quickly locate and sort based on this specific area, thereby reducing the sorting range and improving the impurity separation efficiency.
