Description

Technical Field

[0001] The present invention relates to the field of sorting equipment, and specifically to a sorting device for crushing and recycling perlite board waste materials. Background Art

[0002] During the processing of expanded perlite boards, a crushing device is required to crush them; although the existing crushing devices for processing expanded perlite boards can meet the basic requirements for crushing perlite, and in order to prevent large perlite particles that are not thoroughly crushed from being mixed with thoroughly crushed small perlite particles during discharging and affecting the subsequent processing process, people often use a sieve structure to screen the crushed perlite particle materials. However, after a period of use, a large number of large-volume perlite particle materials will be intercepted on the sieve structure. Users often need to spend a lot of time and effort to remove the sieve structure, clean the large-volume perlite particle materials intercepted in the sieve structure, and then spend a lot of time and effort to install the sieve structure back into the crushing device to continue crushing the perlite particle materials. Due to the need to spend a lot of time and effort for disassembly and installation, it brings great inconvenience to people's use and also affects the efficiency of crushing the perlite particle materials;

[0003] To solve the above problems, after searching, a Chinese patent with the publication number CN221268254U discloses a crushing device for processing expanded perlite, which includes a crushing box with openings at both the upper and lower ends and a conical shape at the lower end. Support legs are provided at the bottom corners of the crushing box. The top of the crushing box is detachably provided with a box cover. A crushing module is provided at the upper end inside the crushing box. A feed hopper adapted to the crushing module is provided on the box cover. Horizontal plates are respectively provided on the outer side walls of the left and right sides at the lower part of the crushing box. Telescopic push rods are respectively vertically provided on the two horizontal plates. The lower ends of the output shafts of the telescopic push rods are jointly provided with a horizontally distributed U-shaped mounting frame. A sieve filter cylinder that can be detachably fixed to the bottom of the crushing box is rotatably provided in the mounting frame. An adjustment module for driving the rotation of the sieve filter cylinder is provided on the mounting frame. A stirring module adapted to the sieve filter cylinder is provided at the lower end inside the crushing box;

[0004] Although the above device can crush and process perlite, in actual use, the perlite contains wire meshes or iron impurities are mixed in during the use process; if the mixed iron wires cannot be removed before the perlite is crushed and processed, the hardness of metal impurities such as iron wires is relatively high, and they will cause wear, scratches, and even damage to components such as the cutting tools and grinding disks of the crushing equipment during the crushing process, shortening the service life of the equipment, increasing the equipment maintenance cost and downtime, and affecting the production efficiency.

[0038] Working principle: When in actual use, a large amount of perlite boards to be crushed are first put into the interior of the jaw crusher. The jaw crusher can perform the first-stage crushing work on a large amount of perlite. Subsequently, the perlite after the first-stage crushing enters the conveyor belt 2 of the jaw crusher. After being lifted by the conveyor belt 2 of the jaw crusher, it is conveyed to directly above the receiving hopper 12. When the crushed material falls from the end of the conveyor belt 2 of the jaw crusher, it moves in a parabolic motion and impacts on the strong magnetic drum 32 on the surface of the magnetic separation mechanism 3. At this time, the rotation direction of the strong magnetic drum 32 is counterclockwise. Metal particles or iron wires in the crushed material can impact on the strong magnetic drum 32 and synchronously perform the adsorption work; the strong magnetic drum 32 can generate a strong magnetic field, which has a strong attraction to metal particles and iron wires, and can quickly and effectively adsorb them from the perlite powder, with high impurity removal efficiency, and can significantly improve the purity of the perlite powder; during the perlite crushing process, impurities such as metal particles or iron wires may cause wear, blockage, or even damage to subsequent processing equipment such as grinders and sieving machines. By removing these impurities in advance through the strong magnetic drum 32, the service life of the equipment can be extended, the equipment maintenance cost and downtime can be reduced, and the smooth progress of the production process can be ensured; the perlite powder after removing metal impurities has better quality, higher purity, and more stable performance; this is crucial for the application of perlite in some fields with strict requirements for impurity content, such as horticulture, building insulation, and filter materials, and can improve the market competitiveness of the product; the operation of the strong magnetic drum 32 is relatively simple. Only by conveying the crushed perlite material to the strong magnetic drum 32 through a conveyor belt or other means can automatic adsorption and impurity removal be achieved, without complex operation processes and professional skills, and it is easy for workers to master and operate; no chemical agents need to be used, no secondary pollution will be generated, meeting environmental protection requirements; at the same time, the energy consumption of the strong magnetic drum 32 is relatively low. While achieving efficient impurity removal, it helps to reduce production costs and achieve energy conservation and consumption reduction; when the metal material attached to the outer surface of the strong magnetic drum 32 rotates counterclockwise, scraping work can be carried out through the scraping plate 35. As a result, more and more impurities accumulate on the top of the scraping plate 35 and naturally fall into the interior of the blanking rail 36. A collection box can be provided at the bottom of the blanking rail 36 to collect the metal impurities falling inside the blanking rail 36; as the strong magnetic drum 32 adsorbs metal impurities, the accumulation of metal on its surface will affect the adsorption effect of the magnetic field on metal impurities in subsequent materials; the scraping plate 35 can timely scrape off the metal material, enabling the surface of the strong magnetic drum 32 to remain clean, maintaining a stable and strong magnetic field intensity, and ensuring the impurity removal efficiency; preventing the excessive accumulation of metal impurities on the surface of the strong magnetic drum 32 from forming lumps or thick layers; if too many impurities accumulate, they may fall off and mix back into the perlite powder, or affect the normal operation of the scraping plate 35, or even damage the equipment. The scraping plate 35 can effectively prevent this situation from occurring;Metal impurities attached to the surface of the strong magnetic roller 32 for a long time may cause damage to the roller surface due to factors such as friction and corrosion; the scraper plate 35 scrapes off the impurities, which can reduce the contact time between the impurities and the roller surface, protect the metal surface of the roller, and extend the service life of the equipment; timely scraping off the adsorbed metal impurities allows the strong magnetic roller 32 to adsorb new metal impurities with a clean surface every time it rotates, thereby improving the removal accuracy of metal impurities in the perlite powder and making the final product higher in purity; the perlite material with metal impurities removed enters the interior of the receiving hopper 12, and enters the interior of the double-roll crusher 1 for secondary crushing. The jaw crusher has a large crushing ratio and can perform preliminary coarse crushing on the perlite board to greatly reduce its particle size; the double-roll crusher 1 can further perform medium and fine crushing on the coarsely crushed material. Through the combination of the two, a large total crushing ratio can be achieved, and the perlite board can be crushed into smaller particles to meet the requirements of perlite particle size in different application scenarios; during the crushing process, the jaw crusher mainly crushes the material by extrusion and bending, and can crush large pieces of perlite board into more regular block particles; the double-roll crusher 1 adopts extrusion and grinding. The grinding method can make the material be squeezed and sheared between two rollers rotating in opposite directions, and further crushed into particles with more uniform particle size and more regular shape, which is beneficial to improving the quality and performance of perlite products; the roller crusher 1 and the jaw crusher can be directly purchased and used on the market; the material crushed by the roller crusher 1 impacts the surface of the vibrating screen 40, and the powder collector 41 and the particle collector 43 are respectively installed on both sides of the surface of the vibrating screen 40. The powder collector 41 can receive the powder and pass it through the powder discharge frame 42 At the same time, the granular materials can be filtered from the granular collector 43 and discharged and collected from the granular material discharge frame 44; finally, the materials with particles larger than the filter hole size on the granular collector 43 are discharged and collected from the leftmost end of the vibrating screen 40, so that the perlite powder can be sorted and collected according to three size standards; through the coordinated work of the powder collector 41, the granular collector 43 and the vibrating screen 40, the perlite powder can be accurately separated according to different particle size ranges to meet different applications. Strict requirements on perlite particle size in different application scenarios; for example, in the field of horticulture, different plants may require perlite of different particle sizes to ensure the air permeability and water retention of the soil; in building insulation materials, perlite of a specific particle size can better exert its thermal insulation performance; collecting perlite powder by particle size classification can avoid mixing particles of different particle sizes together, resulting in unstable product quality; after precise sorting, products of each particle size level have a more uniform particle size distribution and better physical properties, thereby improving the overall quality and market competitiveness of the product;This sorting method can make full use of perlite raw materials, effectively collect and classify particles of different particle sizes, enable reasonable application of perlite powder of each particle size, reduce the situation of being discarded or wasted due to non-compliance with particle size requirements, and improve the utilization rate of resources; the vibrating screen 40 is integrally inclined to facilitate the movement and sorting of materials thereon, and a vibrating motor is also installed on the vibrating screen 40.

The cross-sections of the positioning grooves 322 and the positioning seats 321 are both circular; the positioning seats 321 are inserted into the positioning grooves 322 and fixed by bolts.

[0040] Specific Embodiment Ten: This embodiment is a further limitation of Specific Embodiment Two.

A bearing fixing seat 345 is movably installed on the outside of the connecting shaft 344, and a receiving hopper 12 is fixedly arranged on the top of the bearing fixing seat 345.

[0041] The drive shaft 34 drives the high-intensity magnetic roller 32 to rotate. The rotation of the drive shaft 34 is realized through the pulley A 341, pulley B 343, belt 342 and connecting shaft 344. The connecting shaft 344 is fixed to the transmission shaft of the internal crushing roller of the double-roll crusher 1 through a coupling. By using the rotation of the transmission shaft of the crushing roller, the high-intensity magnetic roller 32 is driven to rotate, so that the rotation drive of the high-intensity magnetic roller 32 can be realized without an additional motor, reducing the use of additional motors and related supporting equipment such as motor brackets, couplings, electrical control components, etc., making the structure of the whole equipment more compact and concise, reducing the complexity and floor area of the equipment, and facilitating the installation, maintenance and management of the equipment; on the one hand, the cost of purchasing motors and related control equipment is saved, reducing the initial investment cost of the equipment; on the other hand, due to the simplification of the equipment structure, the maintenance workload and maintenance cost are also reduced accordingly, such as reducing the cost of motor fault repair and replacing motor parts; the power of the transmission shaft of the crushing roller is usually provided by the main motor. Through reasonable transmission design, this part of the power is directly transmitted to the high-intensity magnetic roller to realize the effective utilization of energy, avoiding the energy loss caused by the drive of an additional motor, improving the energy utilization efficiency of the whole system to a certain extent and reducing energy consumption; reducing the use of vulnerable parts such as motors also reduces the possibility of the whole system stopping due to motor failures, improving the stability and reliability of the system, making the production process more continuous and stable, and reducing production delays and losses caused by equipment failures.
