Description

Technical Field

[0001] This invention belongs to the field of glass recycling technology, specifically referring to a glass waste recycling and crushing equipment. Background Technology

[0002] Waste generated during tempered glass production mainly comes from the following stages: First, scraps and defective products with non-compliant dimensions produced during the cutting of raw glass sheets; second, glass fragments generated during edge grinding, drilling, and other processing; third, spontaneous breakage or surface defects caused by uneven heating or improper cooling rates during the tempering process; and finally, substandard products found during the finished product inspection stage due to uneven stress, deformation, or the presence of impurities. These wastes can be categorized by form into large scraps, granular fragments, and powdery dust.

[0003] For the recycling of the aforementioned waste materials, crushing them and using them as raw materials for melting new glass is usually adopted. However, in practice, over-crushing often occurs. Over-crushing refers to the glass particles being too fine after crushing (e.g., less than 0.5 mm), which makes them easy to scatter and be lost during recycling and melting, increases energy consumption, and the excessively fine powder may affect the uniformity of the molten glass. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide a glass waste recycling and crushing device to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by this invention is as follows: A glass waste recycling and crushing equipment is proposed, comprising: A crusher, the crusher including a crushing chamber and a feed hopper and a discharge hopper respectively disposed at the input / output end of the crushing chamber; The crushing disc assembly includes a fixed crushing disc and a movable crushing disc disposed inside the crushing chamber. The fixed crushing disc is fixed to the inner wall of the crushing chamber, and the movable crushing disc is configured to rotate under drive. A driver is installed on the crushing chamber and drives the movable crushing disc to rotate relative to the fixed crushing disc; The crushing chamber includes a first crushing chamber, a second crushing chamber, and a third crushing chamber arranged coaxially and with progressively increasing diameters. Each of the first, second, and third crushing chambers has a crushing cavity inside. Each crushing cavity has a crushing disc assembly inside, and each crushing cavity has a screen plate at its bottom. The screen aperture of the screen plate gradually decreases along the material flow direction. After passing through the screen plate, the material enters the rear crushing cavity, causing the material to flow sequentially through the first, second, and third crushing chambers and be graded and screened by the screen plate.

[0006] Furthermore, the second and third crushing chambers are provided with feed windows on their bottom sides. The bottom of the first and second crushing chambers is provided with guide hoods corresponding to the bottom of the screen plate. The guide hoods are configured to guide the material falling into the feed guide hopper to the feed window. The top of the first crushing chamber is fixedly provided with a feed hopper, and the bottom of the third crushing chamber is fixedly provided with a discharge hopper. The material entering the feed hopper is crushed step by step through the first, second and third crushing chambers and then discharged from the discharge hopper.

[0007] Furthermore, the driver includes a motor and a drive shaft fixed to the output shaft of the motor. The drive shaft is located on the central axis of the crushing chamber. The outer wall of the drive shaft is provided with a hinged ball head corresponding to each of the movable crushing discs. The center of each movable crushing disc is provided with a hinged cavity that cooperates with the hinged ball head. When the drive shaft rotates around the axis, the movable crushing disc can rotate with the drive shaft, and the plane where the movable crushing disc is located is not perpendicular to the axis of the drive shaft.

[0008] Furthermore, the crushing disc assembly also includes a support base. The fixed crushing disc and the support base are respectively fixed to the inner walls of both sides in the axial direction of the crushing chamber. The movable crushing disc is disposed between the fixed crushing disc and the support base. The movable crushing disc is constructed as a disc body. One side of the movable crushing disc opposite to the fixed crushing disc is set as a working surface, and the other side is set as a supporting surface. The supporting surface slides in contact with the support base.

[0009] Furthermore, the side of the fixed crushing disc facing the movable crushing disc is configured as a crushing surface, the crushing surface includes a first crushing surface and a second crushing surface symmetrically distributed at the top and bottom, the working surface is distributed parallel to the second crushing surface, and the working surface has an angle of ~° with the first crushing surface.

[0010] Furthermore, multiple guide shovels are fixedly provided on the outer periphery of the movable crushing disc. The guide shovels are configured to scoop up the material at the bottom of the crushing chamber when they rotate to the bottom of the crushing chamber, and to allow the scooped material to slide down between the crushing surface and the working surface when the guide shovels rotate to the upper part.

[0011] Furthermore, multiple second cutter head modules are fixed on the working surface of the movable crushing disc. The surface of the second cutter head module is provided with multiple protruding second crushing blades, and the second crushing blades include cylindrical blades with a cross-section of regular hexagon and / or "L".

[0012] Furthermore, a plurality of first cutter disc modules are fixedly provided on the crushing surface of the fixed crushing disc, and a plurality of protruding first crushing blades are provided on the surface of the first cutter disc modules. The first crushing blades include cylindrical blades with cross-sections of regular hexagons, "I" shapes and / or "L" shapes.

[0013] Furthermore, the plurality of second cutter head modules are centrally symmetrically distributed around the center of the movable crushing disc, and the protrusion height of the plurality of second cutter head modules on the surface of the movable crushing disc increases sequentially.

[0014] Furthermore, the fixed crushing disc is equipped with a vibration exciter inside, and the working surface of the vibration exciter faces the first cutter head module.

[0015] Beneficial effects: This invention utilizes a multi-stage coaxial crushing chamber with progressively increasing diameters, and each chamber is equipped with an independent crushing disc assembly and screen plate. This enables the step-by-step crushing and grading of glass waste, effectively avoiding over-grinding caused by excessive grinding within the same crushing chamber, thus improving crushing efficiency and product particle size uniformity. The movable crushing disc is connected to the drive shaft via a hinged ball joint, creating a dynamic crushing surface with the fixed crushing disc at a non-parallel angle during rotation. This enhances shearing and crushing effects. The crushing blades, combined with a vibration exciter, can achieve vibration-induced cracking based on the internal stress characteristics of tempered glass, reducing crushing energy consumption and extending blade life.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0020] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0021] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a glass waste recycling and crushing device, including a crusher 10, a driver 20, and a crushing disc assembly 30.

[0022] The crusher 10 constitutes the main structure of the equipment. The crushing chamber 11 is a horizontally arranged cylindrical structure, which is fixed on the support 14. The crushing chamber 11 has three crushing chambers 100 with increasing diameters arranged in sequence along the axial direction. The feed hopper 12 is installed on the top of the first crushing chamber 111 for feeding glass waste to be crushed. The discharge hopper 13 is located at the bottom of the third crushing chamber 113 for discharging the final qualified crushed material. The crushing disc assembly 30 includes a fixed crushing disc 31 and a movable crushing disc 32 installed inside the crushing chamber 11. The fixed crushing disc 31 is fixed to the inner wall of the crushing chamber 11. The movable crushing disc 32 is configured to be driven to rotate. The driver 20 is installed on the crushing chamber 11 and drives the movable crushing disc 32 to rotate relative to the fixed crushing disc 31. During operation, the driver 20 drives the movable crushing disc 32 to rotate, so that it forms a relative motion with the fixed crushing disc 31, thereby realizing the extrusion, shearing and grinding of the material.

[0023] Furthermore, the crushing chamber 11 adopts a structure in which the first crushing chamber 111, the second crushing chamber 112, and the third crushing chamber 113 are connected in series on the same axis, with the diameters of the three increasing sequentially to accommodate the gradual decrease in volume and increase in quantity of materials during the crushing process. Each crushing chamber 100 is equipped with a crushing disc assembly 30, and each crushing chamber 100 has a screen plate 1101 at its bottom. The aperture of the screen plate 1101 decreases progressively along the material flow direction. After the material is initially crushed by the crushing disc assembly 30 in the crushing chamber 100, only when the particle size is smaller than the aperture of the screen can it pass through the screen plate 1101 and fall into the next stage crushing chamber 100. This allows the material to flow sequentially in the first crushing chamber 111, the second crushing chamber 112, and the third crushing chamber 113 and be graded and screened by the screen plate 1101, thereby achieving graded crushing of materials and avoiding over-crushing and energy waste.

[0024] In a specific embodiment, in order to achieve orderly flow of materials between the crushing chambers at each level, the bottom of the side walls of the second crushing chamber 112 and the third crushing chamber 113 are respectively provided with feed windows 110, and the screen plates 1101 of the first crushing chamber 111 and the second crushing chamber 112 are both provided with guide hoods 114, which form a material discharge guide chamber 1140 inside.

[0025] The guide hood 114 is configured to guide the material falling after the previous stage of screening to the side feed window 110. A feed hopper 12 is fixedly installed at the top of the first crushing chamber 111, and a discharge hopper 13 is fixedly installed at the bottom of the third crushing chamber 113. After entering through the feed hopper 12, the material undergoes progressive crushing and screening through the first crushing chamber 111, the second crushing chamber 112, and the third crushing chamber 113, and is finally discharged from the discharge hopper 13. This ensures that the material flows along a predetermined path within the equipment, resulting in a compact overall structure and smooth material flow.

[0026] like Figure 2 and Figure 3 As shown, the driver 20 further includes a motor 21 and a drive shaft 22 fixed to the output shaft of the motor 21. The other end of the drive shaft 22 is connected to a bearing 23 on the crushing chamber 11, so that the drive shaft 22 can ensure stable operation. The drive shaft 22 is located on the central axis of the crushing chamber 11, and its outer wall is provided with a hinged ball joint 221 corresponding to each movable crushing disc 32.

[0027] Correspondingly, the movable crushing disc 32 has a hinge cavity 320 at its center that mates with the hinge ball head 221, forming a ball-joint connection. The outer wall of the hinge ball head 221 has a protruding arc-shaped structure, and the hinge cavity 320 has a corresponding groove. Thus, when the drive shaft 22 rotates around its axis, the movable crushing disc 32 can rotate with the drive shaft 22. Due to the ball-joint connection, the plane of the movable crushing disc 32 can maintain a non-perpendicular angle with the axis of the drive shaft 22. This connection method allows the movable crushing disc 32 to adaptively deflect within a certain angle range while revolving, thereby creating a non-uniform gap between its working surface and the crushing surface of the fixed crushing disc 31, enhancing the kneading and shearing effect on the material.

[0028] Furthermore, to improve the operational stability of the movable crushing disc 32, the crushing disc assembly 30 also includes a support base 33. The fixed crushing disc 31 and the support base 33 are respectively fixed to the inner walls of both sides in the axial direction of the crushing chamber 11. The movable crushing disc 32 is disposed between the fixed crushing disc 31 and the support base 33. The movable crushing disc 32 is constructed as a disc body. One side of it opposite to the fixed crushing disc 31 is set as the working surface, and the other side is set as the supporting surface. The supporting surface slides in contact with the support base 33, playing an auxiliary support and guiding role, and preventing the movable disc from generating excessive vibration or displacement during rotation.

[0029] In some embodiments, the side of the fixed crushing disc 31 facing the movable crushing disc 32 is designated as a crushing surface. This crushing surface includes a first crushing surface and a second crushing surface symmetrically distributed vertically. The working surface of the movable crushing disc 32 is parallel to the second crushing surface, and the working surface has an angle of 20–30° with the first crushing surface. This angled structure allows the material to first undergo guidance and pre-compression by the inclined surface upon entering the crushing zone, and then enter the parallel surface for fine grinding, improving the gradualness and stability of the crushing process.

[0030] like Figure 4 , Figure 5 and Figure 6As shown, furthermore, multiple guide shovels 322 are fixedly provided on the outer periphery of the movable crushing disc 32. The guide shovels 322 are configured to scoop up the material deposited at the bottom when they rotate with the movable crushing disc 32 to the bottom of the crushing chamber 100. When the guide shovels 322 rotate to the upper part, the scooped material naturally slides down under the action of gravity between the crushing surface of the fixed crushing disc 31 and the working surface of the movable crushing disc 32. This effectively prevents the material from accumulating at the bottom of the chamber and improves the circulation and crushing uniformity of the material in the crushing chamber 100.

[0031] Multiple second cutter head modules 321 are fixed on the working surface of the movable crushing disc 32. The surface of the second cutter head module 321 is provided with multiple protruding second crushing blades 3211. The second crushing blades 3211 include cylindrical blades with a cross-section of regular hexagon and / or "L" shape. These asymmetrical, multi-faceted blade shapes can generate multi-directional cutting forces during the crushing process, enhancing the crushing effect on glass particles.

[0032] In some embodiments, the arrangement of crushing blades with different cross-sectional shapes can create non-uniform flow resistance in the crushing area, slowing down the passage speed of glass fragments between the blades and subjecting them to more thorough shearing and crushing. The hexagonal cross-section blades have good torsional strength and wear resistance, while the "L"-shaped blades can form guiding, flow-continuing and scraping effects. The combination of the two can improve crushing efficiency and reduce blade wear.

[0033] Furthermore, multiple first cutter disc modules 311 are fixedly provided on the crushing surface of the fixed crushing disc 31. The surface of the first cutter disc module 311 is provided with multiple protruding first crushing blades 3111. The first crushing blades 3111 include cylindrical blades with cross-sections of regular hexagons, "I" shapes, and / or "L" shapes. The "I" shaped blades are suitable for splitting and piercing materials. When combined with blades of other shapes, they can form a multi-mode crushing action to meet the crushing needs of glass with different particle sizes.

[0034] In some embodiments, a plurality of second cutter head modules 321 are centrally symmetrically distributed around the center of the movable crushing disc 32, and the protrusion height of the plurality of second cutter head modules 321 on the surface of the movable crushing disc 32 increases radially, with the total increase in height being within 1 to 2 mm. This stepped layout allows the material to undergo gradually enhanced crushing action as it moves from the center of the disc to the edge, which is beneficial for achieving progressive crushing of the material and avoiding instantaneous overload.

[0035] In an optional embodiment, a vibration exciter 312 is provided inside the fixed crushing disc 31. The working surface of the vibration exciter 312 faces the first cutter disc module 311. The vibration exciter 312 can apply high-frequency micro-amplitude vibration to the fixed crushing disc 31 during the crushing process. This design utilizes the prestress characteristics existing inside the tempered glass to induce the propagation of micro-cracks inside the glass through vibration transmission, thereby achieving vibration-induced cracking, reducing the energy consumption of mechanical crushing, improving crushing efficiency, and reducing the impact wear of the cutter.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
