Description

Technical Field

[0001] This invention belongs to the field of air classifier technology, specifically relating to a small hanging air classifier. Background Technology

[0002] With the deepening of environmental protection concepts and the increasing demand for resource recycling, the construction waste recycling industry has experienced rapid development. Crushing and processing waste concrete, bricks, and other construction waste into recycled aggregates has become an important way to alleviate resource shortages and reduce solid waste pollution. In the construction waste recycling process, the crushed mixture often contains lightweight impurities such as sawdust, adhesive paper, and cardboard. These impurities severely affect the key properties of the recycled material, such as strength and density, leading to a reduction in its usability. Therefore, air separation equipment is needed to separate the light and heavy materials in the mixture; this step has become one of the core processes determining the quality of the recycled material.

[0003] Currently, commonly used air separation equipment in the industry is mainly divided into two categories: large fixed air separators and simple air separation devices. Although large fixed air separators have high separation efficiency, they are bulky, complex in structure, require separate installation space, and have high equipment and maintenance costs, making them unsuitable for the production scenarios of small and medium-sized recycled material processing enterprises, especially unsuitable for the on-site air separation needs at the crusher discharge end. Simple air separation devices (such as small inclined air separation troughs) mostly rely on natural airflow or simple fans for air supply, lack precise control over airflow angle and volume, and do not have a dedicated material dispersion structure, causing the mixed material to easily accumulate in the air separation area.

[0004] Existing air separation equipment has significant drawbacks: First, it lacks adaptability. Large-scale equipment cannot meet the space and cost requirements of small and medium-sized enterprises, while simple devices are difficult to match the immediate processing scenarios at the crusher outlet. There is a lack of miniaturized equipment that can be easily mounted on the crusher outlet. Second, the separation effect is unstable. Due to the lack of an effective material dispersion mechanism, the mixture is unevenly dispersed, and light and heavy materials are easily mixed together. At the same time, the airflow parameter adjustment is inflexible, and it is impossible to dynamically optimize the air separation conditions according to the characteristics of light material content and particle size in the mixture, resulting in incomplete separation, high light material residue, or heavy material loss with light material. Third, the quality assurance of recycled materials is insufficient. The above-mentioned defects ultimately lead to large fluctuations in the impurity content of the processed recycled materials, and the strength, uniformity, and other properties are difficult to meet the standards, which limits the application scope of recycled materials in construction projects and fails to fully realize the recycling value of construction waste. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies and solve the problems of existing air classifiers being unable to flexibly adapt to the discharge end of crushers, requiring additional installation space and conveying devices, uneven dispersion of mixed materials leading to incomplete separation of light and heavy materials, unadjustable airflow parameters affecting air classifier performance, and easy leakage during light material collection and residue during heavy material discharge, this invention proposes a small hanging air classifier.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A small hanging air separator includes:

[0008] The air separator, as the main frame of the equipment, is used to contain airflow and form an air separation space to achieve the wind-driven separation of heavy materials and light materials;

[0009] The feed hopper, located above the air classifier, is used to receive the mixture of crushed construction waste, ensuring that the mixture enters the air classifier evenly.

[0010] Air inlet baffles are installed at the air inlet end of the air separator to adjust the air inlet angle and air volume, thereby optimizing the air separation effect;

[0011] The discharge port is located at the bottom of the air separator and is used to discharge the useful heavy material (stones and sand) after separation.

[0012] The mesh bag flange is located at the lightweight material outlet end of the air separator and is used to connect the collection bag to collect the separated lightweight materials (wood chips, adhesive paper, cardboard, and other impurities).

[0013] The vibrating screen assembly uses a vibrator to generate vibration, which drives the vibrating screen to vibrate, so that the incoming mixture is evenly dispersed, improving the uniformity and separation effect of air classification.

[0014] By working in concert with multiple components, it takes into account both air separation and material dispersion, effectively removing light impurities from construction waste mixtures and improving the purity of recycled heavy materials.

[0015] Preferably, the vibrating screen assembly includes a vibrator, a vibrating screen, a spring hook, a vibrator fixing plate, a vibrating screen frame, and vibrating screen side plates; the vibrator is fixed to the vibrating screen side plates on both sides by the vibrator fixing plate, the vibrating screen is set on the vibrating screen frame and located below the vibrator fixing plate, and the two vibrating screen side plates are set on the sides of the vibrating screen frame.

[0016] The spring hook includes an upper spring hook and a lower spring hook. The upper spring hook is fixed to the top of the inner side of the air separator box, and the lower spring hook is fixed to the side plate of the vibrating screen. The spring connecting the upper spring hook and the lower spring hook is used to achieve the elastic suspension of the vibrating screen assembly. The structure has a clear division of labor. The elastic suspension buffers the vibration impact, which not only ensures the vibration dispersion effect, but also reduces the wear of parts and extends the service life of the vibrating screen assembly.

[0017] As a preferred option, the vibrator is a YZu-3-4-0.18 model vibrator. There is only one vibrator, which is fixedly installed at the center of the vibrator fixing plate and above the center of the vibrating screen. It is used to provide vibration power for the vibrating screen. The single vibrator is centrally located, and the power output is uniform and stable, which is precisely adapted to the needs of small equipment and ensures that the overall dispersion effect of the vibrating screen is consistent.

[0018] Preferably, the feed hopper is a bucket-shaped structure with an opening at the top, and its bottom discharge end is connected to the feed area of ​​the air classifier. A funnel fixing plate is provided between the feed hopper and the air classifier to fix the position of the feed hopper. The bucket-shaped structure can easily receive the mixed material, and the fixing plate ensures the stability of the position, so as to realize that the mixed material enters the air classifier evenly and smoothly and avoid feed deviation.

[0019] Preferably, the air separator is a rectangular frame structure with an internal cavity for air separation. The air outlet baffle is a plate-shaped structure that matches the shape of the air inlet end of the air separator and is detachably installed at the air inlet end of the air separator to adjust the air inlet angle and air volume. The air inlet end of the air separator is provided with an air inlet duct located inside the air outlet baffle and connected to the air outlet baffle. The retaining ring at the inner end of the air inlet duct is engaged with the toothed groove fixed inside the air separator.

[0020] The air inlet is located at the outlet of the air inlet and below the feed hopper, and an air guide is provided. The rectangular cavity provides a regular air separation space. The detachable baffle makes it easy to adjust the air volume angle. The air inlet and air guide accurately guide the airflow and optimize the air separation.

[0021] As a preferred option, the discharge port is a funnel-shaped structure, with only one outlet, and is vertically aligned with the feed hopper and the feeding area. The funnel-shaped structure concentrates the discharge, and the vertical alignment design reduces the residue of heavy materials, achieving efficient and residue-free discharge of heavy materials after separation.

[0022] As a preferred option, the mesh bag flange is a square frame structure, with only one flange covering the outside of the vibrating screen. The square frame structure is compatible with the installation of the collection bag, covering the vibrating screen to ensure complete collection of light materials, prevent leakage of light materials, and improve the integrity of impurity collection.

[0023] Preferably, the vibrating screen is a U-shaped plate structure with screen holes, horizontally set on the vibrating screen frame, with the feed end of the vibrating screen corresponding to the discharge end of the feed hopper, used to receive and disperse the mixture. The U-shaped structure can accommodate more mixture, the screen holes assist in preliminary screening, and the horizontal installation corresponds to the feed end, so as to achieve uniform reception and dispersion of the mixture and enhance the air classification contact effect.

[0024] Preferably, the vibrating screen frame is a rectangular frame structure with a reinforcing crossbeam in the middle of the rectangular frame, and the vibrator fixing plate is a horizontal plate structure. The reinforcing crossbeam improves the load-bearing capacity and stability of the frame, and the horizontal fixing plate ensures that the vibrator is firmly installed and ensures stable transmission of vibration power.

[0025] As a preferred option, the top of the air classifier is equipped with lifting lugs for suspending the air classifier at the outlet end of the crusher discharge conveyor belt, thus achieving convenient mounting.

[0026] The lifting lugs are plate-shaped structures with mounting holes. The lifting lugs are located on both sides of the top of the air classifier box and are used to suspend the equipment with the lifting equipment. The lugs with holes facilitate the installation with the lifting equipment, and the layout on both sides ensures the stability of the suspension and achieves seamless connection between the equipment and the crusher without the need for additional installation space.

[0027] Compared with the prior art, the technical effects and advantages of the present invention are:

[0028] Compared to existing large-scale air separation equipment that requires separate installation space and smaller equipment that is difficult to connect to crushers, this invention, with its top lifting lug design, can be directly suspended and installed at the outlet end of the crusher's discharge conveyor belt. This eliminates the need for additional conveying devices and installation sites, significantly simplifying the installation process and saving labor and time costs. Furthermore, the equipment's compact structure allows for flexible adaptation to the production scenarios of small and medium-sized recycled material processing enterprises, enabling immediate air separation after crusher discharge. This prevents secondary mixing of materials during transport, filling a gap in existing equipment offering immediate connection and convenient installation.

[0029] Existing equipment often suffers from incomplete separation due to uneven dispersion of the mixture and fixed airflow parameters. This invention fundamentally solves this problem through the synergistic design of a vibrating screen assembly and an air vent baffle. The vibrating screen assembly uses vibration to evenly disperse the mixture, preventing localized accumulation or clumping and increasing the contact area between the mixture and the airflow. The air vent baffle allows for flexible adjustment of the inlet angle and airflow, and, in conjunction with the air inlet duct and guide vent, precisely guides the airflow, dynamically optimizing air separation conditions based on the mixture characteristics to ensure more thorough separation of light and heavy materials. Furthermore, the outlet and inlet areas are vertically aligned and employ a funnel-shaped structure to reduce heavy material residue. The mesh bag flange, combined with sealing strips, achieves sealed collection of light materials, further improving separation accuracy and effectively preventing light material residue or heavy material loss, ensuring stable and compliant recycled material quality.

[0030] The air separator box of this invention adopts a metal material and a cuboid frame design, which can not only stably support all components, but also form a regular air separation space, ensuring the structural stability of the equipment during long-term operation. The vibrating screen assembly is elastically suspended by spring hooks, which buffers vibration impact, reduces component wear, and extends the service life of the vibrating screen assembly. The centrally fixed layout of the vibrator and the horizontal plate-shaped vibrator fixing plate ensure uniform transmission of vibration power and avoid component wear caused by uneven vibration. Details such as rust-proof treatment of the air outlet baffle surface and the addition of reinforcing crossbeams to the vibrating screen frame further enhance the durability of the equipment and reduce the frequency and cost of later maintenance.

[0031] This invention, through the sealing design of the mesh bag flange, prevents leakage of lightweight materials and escape of impurities, reducing environmental pollution and meeting environmental protection production requirements. In terms of economy, the equipment requires no complex supporting facilities, with initial investment costs lower than large-scale air separation systems. Furthermore, due to improved structural durability and reduced maintenance costs, it offers a more advantageous long-term operating cost. Simultaneously, the equipment improves the quality of recycled materials through efficient separation, expanding the application range of recycled materials and helping enterprises improve resource utilization and product added value. It provides a more cost-effective solution for the large-scale, high-quality development of the construction waste recycling industry. Attached Figure Description

[0039] The technical solutions of 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 of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0041] This application discloses a small hanging air separator, including an air separator box 1, a feed hopper 2, an air outlet baffle 3, a discharge port 4, a mesh bag flange 5, a vibrating screen assembly 6, and a lifting lug 12;

[0042] The air classifier 1, serving as the main frame of the equipment, accommodates the airflow and forms the air classification space, enabling the aerodynamic separation of heavy and light materials. The air classifier 1 has a rectangular frame structure with internal cavities for air classification. Made of metal, it possesses sufficient strength to support all components. The high strength of the metal material ensures stable support for all parts, guaranteeing structural stability during equipment operation. The rectangular frame combined with the internal cavity provides ample and well-organized air classification space for the airflow and the mixture, facilitating efficient separation of heavy and light materials.

[0043] The feed hopper 2 is positioned above the air classifier 1 to receive the mixed material after crushing construction waste, ensuring the mixture enters the air classifier 1 evenly. The feed hopper 2 has a top-opening, bucket-shaped structure, with its bottom outlet connected to the feed area 7 of the air classifier 1. A funnel fixing plate 8 is installed between the feed hopper 2 and the air classifier 1 to fix the position of the feed hopper 2. The inner wall of the feed hopper 2 is smooth, facilitating the smooth flow of the mixed material into the air classifier 1. The bucket-shaped structure of the feed hopper 2 can easily accommodate large quantities of mixed material and guide it evenly into the air classifier 1. The funnel fixing plate 8 ensures the stability of the feed hopper 2, preventing displacement during operation. The smooth inner wall reduces the resistance to the sliding of the mixed material, allowing it to smoothly enter the air classifier 1 and improving feeding efficiency.

[0044] The air inlet baffle 3 is installed at the air inlet end of the air classifier box 1 to adjust the air inlet angle and air volume, and optimize the air classification effect. The air inlet baffle 3 is a plate-shaped structure adapted to the shape of the air inlet end of the air classifier box 1. It is detachably installed at the air inlet end of the air classifier box 1 to adjust the air inlet angle and air volume. The air inlet end of the air classifier box 1 is provided with an air inlet duct 9 located inside the air inlet baffle 3 and connected to the air inlet baffle 3. The retaining ring 10 at the inner end of the air inlet duct 9 is engaged with the toothed groove 11 fixed inside the air classifier box 1. The outlet of the air inlet duct 9 and located below the feed hopper 2 is provided with an air guide vent 13. The surface of the air inlet baffle 3 is rust-proofed to extend its service life. The detachable design of the air outlet baffle 3 facilitates installation, maintenance and adjustment; by adjusting the air inlet angle and air volume, it can adapt to mixtures with different characteristics and optimize the air separation effect; the air inlet duct 9 and the air guide vent 13 guide the airflow to act precisely on the mixture, enhancing the separation targeting; the rust prevention treatment extends its service life and reduces equipment maintenance costs.

[0045] The discharge port 4 is located at the bottom of the air separator 1 and is used to discharge the useful heavy materials (pebbles and sand) after separation. The discharge port 4 has a funnel-shaped structure, and there is only one of them. It is vertically aligned with the feed hopper 2 and the feeding area 7. The funnel-shaped structure of the discharge port 4 can guide the heavy materials to be discharged in a concentrated manner, avoiding the residue of heavy materials. The vertical alignment with the feeding area allows the heavy materials to be discharged from the discharge port 4 more efficiently and accurately under the combined action of gravity and airflow, thereby improving the collection efficiency of heavy materials.

[0046] The mesh bag flange 5 is located at the light material outlet end of the air separator 1 and is used to connect to the collection bag to collect the separated light materials (wood chips, adhesive tape, cardboard, and other impurities). The mesh bag flange 5 has a square frame structure, and there is only one flange, which covers the outside of the vibrating screen 62. The edge of the mesh bag flange 5 is equipped with a sealing strip to enhance the sealing performance of the connection with the collection bag. The square frame structure of the mesh bag flange 5 facilitates the connection with the collection bag, and its position on the outside of the vibrating screen 62 allows for precise collection of light materials. The sealing strip enhances the sealing performance of the connection with the collection bag, preventing leakage of light materials during collection, ensuring the integrity of the light material collection, and also preventing impurities from escaping and affecting the working environment.

[0047] The lifting lugs 12 are located on the top of the air classifier box 1 and are used to suspend the air classifier box 1 at the outlet end of the crusher discharge conveyor belt for convenient installation. The lifting lugs 12 are plate-shaped structures with mounting holes. The lifting lugs 12 are located on both sides of the top of the air classifier box 1 and are used to cooperate with the lifting equipment to suspend and install the equipment. The design of the lifting lugs 12 with mounting holes facilitates the use of lifting equipment and enables the equipment to be quickly and conveniently suspended and installed at the outlet end of the crusher discharge conveyor belt, simplifying the installation process and saving installation time and labor costs.

[0048] The vibrating screen assembly 6 generates vibration through the vibrator 61, which drives the vibrating screen 62 to vibrate, so that the incoming mixture is evenly dispersed, improving the uniformity and separation effect of air classification. The vibration of the vibrating screen assembly 6 makes the mixture more evenly distributed in the air classification box 1, avoiding local accumulation or uneven dispersion, thereby improving the uniformity of air classification, making the separation of heavy and light materials more thorough, and improving the quality of recycled materials.

[0049] The vibrating screen assembly 6 includes a vibrator 61, a vibrating screen 62, spring hooks, a vibrator fixing plate 64, a vibrating screen frame 65, and vibrating screen side plates 63. The vibrator 61 is fixed to the vibrating screen side plates 63 on both sides via the vibrator fixing plate 64. The vibrating screen 62 is set on the vibrating screen frame 65 and located below the vibrator fixing plate 64. The two vibrating screen side plates 63 are set on the sides of the vibrating screen frame 65. The spring hooks include an upper spring hook 66 and a lower spring hook 67. The upper spring hook 66 is fixed to the top inner side of the air separator 1, and the lower spring hook 67 is fixed to the vibrating screen side plate 63. The spring connecting the upper spring hook 66 and the lower spring hook 67 is used to achieve the elastic suspension of the vibrating screen assembly 6. The structural layout of the vibrator 61 enables the power of the vibrator 61 to be transmitted to the vibrating screen 62 stably and efficiently, ensuring the stability and reliability of the vibration of the vibrating screen 62. The elastic suspension method of the spring hooks can buffer the impact force during vibration, reduce the wear of equipment parts, and extend the service life of the vibrating screen assembly 6.

[0050] Vibrator 61 is a YZu-3-4-0.18 model vibrator. There is only one vibrator 61, fixedly positioned at the center of the vibrator mounting plate 64 and above the center of the vibrating screen 62, providing vibration power to the vibrating screen 62. The vibrator 61's power and other parameters are suitable for the needs of a small air classifier. Its single, centrally located position ensures uniform vibration power to the vibrating screen 62, guaranteeing consistent overall vibration and resulting in more even dispersion of the mixture, thus improving the air classification effect.

[0051] The vibrating screen 62 is a U-shaped plate structure with screen holes 69, horizontally set on the vibrating screen frame 65. The feed end of the vibrating screen 62 corresponds to the discharge end of the feed hopper 2, and it is used to receive and disperse the mixture. The vibrating screen 62 receives and disperses the mixture. The U-shaped plate structure can hold more mixture, and the screen hole 69 is designed to initially screen some materials. At the same time, the vibration further disperses the mixture. The horizontal setting and the fact that the feed end corresponds to the feed hopper 2 ensure that the mixture can be smoothly received and evenly distributed into the air classification area under vibration, laying a good foundation for subsequent air classification separation.

[0052] The vibrating screen frame 65 is a rectangular frame structure with a reinforcing crossbeam 68 in the middle. The vibrator fixing plate 64 is a horizontal plate structure. The reinforcing crossbeam 68 enables the vibrating screen frame 65 to stably support the vibrating screen 62, bear the weight of vibration and mixture, and prevent frame deformation. The horizontal plate-shaped vibrator fixing plate 64 provides a stable and horizontal mounting surface for the vibrator 61, ensuring the stability of the vibrator 61 during operation, thereby ensuring the vibration effect of the vibrating screen 62.

[0053] This small hanging air separator utilizes the aerodynamic force of airflow and the vibration dispersion effect of the vibrating screen 62 to separate the mixture of crushed construction waste. Airflow flows within the air separator 1. Due to the different densities of heavy materials (pebbles and sand) and light materials (wood chips, adhesive paper, cardboard, and other impurities), they exhibit different trajectories under the influence of the airflow. Simultaneously, the vibration of the vibrating screen 62 uniformly disperses the mixture, increasing the contact area between the mixture and the airflow, thereby achieving efficient separation of heavy and light materials.

[0054] From the perspective of overall equipment operation, the coordinated operation of each component demonstrates significant advantages. The air classifier 1 is constructed with a rectangular frame made of metal, ensuring structural stability to support all components while providing ample and orderly air classification space; the hopper 2's bucket-shaped design with a smooth inner wall allows for efficient and smooth feeding of the mixture; the air inlet baffle 3 can adjust the air inlet angle and air volume, is rust-proof and easy to maintain, and ensures that the airflow is precisely applied to the mixture; the outlet 4 is funnel-shaped and vertically aligned with the feeding area, improving the efficiency of heavy material collection; the mesh bag flange 5 has a sealing strip to ensure complete collection of light materials without polluting the environment; the lifting lug 12 facilitates quick installation of the equipment, saving installation costs; the vibrating screen assembly 6 uses vibration to evenly disperse the mixture, making air classification more thorough and improving the quality of recycled materials.

[0055] Looking inside the vibrating screen assembly 6, the vibrator 61 is centrally positioned, ensuring uniform vibration of the screen 62 and resulting in better dispersion of the mixture. The U-shaped structure of the screen 62 with sieve holes 69 can accommodate more mixture for initial screening and dispersion. The reinforcing beam 68 of the vibrating screen frame 65 ensures stable support, while the vibrator fixing plate 64 provides a horizontal and stable mounting surface. The elastic suspension of the spring hooks buffers vibration impact, reduces component wear, and extends the service life of the vibrating screen assembly 6. These design details collectively contribute to the efficient, stable, and long-term operation of the equipment, significantly improving the quality and usability of recycled construction waste.

[0056] The working process of this small hanging air separator is as follows:

[0057] S1. Feeding stage: The mixture of crushed construction waste is conveyed to the feed hopper 2 by the discharge conveyor belt of the crusher. With the help of the bucket-shaped and smooth inner wall structure of the feed hopper 2, the mixture slides down smoothly and enters the feeding area 7 of the air classifier 1 evenly through the bottom discharge end.

[0058] S2, Air Separation Stage: The air inlet angle and air volume are adjusted by the air inlet baffle 3, and the airflow enters the air separator 1 through the air inlet duct 9 and the air guide 13. Under the action of the airflow, the dispersed mixture is less affected by gravity and airflow due to its high density, and moves towards the bottom of the air separator 1; the light materials (wood chips, adhesive paper, paperboard and other impurities) are carried by the airflow towards the light material outlet end of the air separator 1 due to their low density.

[0059] S3, Vibration Dispersion Stage: The vibrator 61 (model YZu-3-4-0.18) in the vibrating screen assembly 6 operates, and the generated vibration is transmitted to the vibrating screen 62 through the vibrator fixing plate 64 and the vibrating screen side plate 63. The vibrating screen 62 vibrates on the vibrating screen frame 65, which makes the incoming mixture evenly dispersed. Light materials are carried by the airflow to the light material outlet end of the air separator 1 or fall below the vibrating screen 62. Heavy materials enter the discharge port 4 under the action of the vibrating screen 62. The elastic suspension structure of the spring hook buffers the vibration impact force, ensuring vibration stability and reducing component wear.

[0060] S4. Discharge and Collection Stage: The separated heavy material is discharged through the funnel-shaped discharge port 4 at the bottom of the air separator 1 and piled up; the light material is carried by the airflow to the light material discharge end of the air separator 1 and collected through the collection bag connected to the mesh bag flange 5. The sealing strip on the edge of the mesh bag flange 5 ensures that the light material does not leak during the collection process. The entire equipment is suspended at the outlet end of the crusher discharge conveyor belt by the lifting lugs 12 on both sides of the top, realizing convenient installation and operation.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
