Description
Technical Field
[0001] This utility model relates to the field of waste sorting, and in particular to a novel horizontal air separator. Background Technology
[0002] With increasing urbanization and industrialization, resources are becoming increasingly scarce, while waste is increasing, including construction and renovation waste, electronic waste, industrial waste, household waste, and kitchen waste. While waste is a significant source of recyclable resources, the government is vigorously promoting waste sorting and recycling systems. The recycled waste is processed by coarse crushing equipment into a mixture of small-sized solids, lightweight materials (films, small flakes, etc.), and dust. This mixture is then further separated into heavy materials, film materials, and dust by multiple sorting devices. However, this system has several drawbacks: First, current sorting devices require multiple sorting and transfer conveying systems to complete the sorting process, resulting in complex equipment, large footprint, high energy consumption, and high costs. Second, film materials easily clog the sorting equipment, requiring frequent maintenance and causing equipment downtime, thus affecting sorting efficiency. Third, the purity of heavy materials, film materials, and dust is insufficient; heavy materials contain film materials and dust, and film materials contain dust, hindering the reuse of the sorted products. Utility Model Content
[0003] To address one or more of the aforementioned problems, this utility model provides a novel horizontal air separator.
[0004] According to one aspect of the present invention, the novel horizontal air separator includes: a horizontal sorting body, a first belt conveyor, a second belt conveyor, an air supply unit, a cyclone separator, and a dust collector.
[0005] The horizontal sorting chamber of the main body is hollow inside and open at the bottom. A flow pipe is fixed in the middle of the upper end of the horizontal sorting chamber. The inner ends of two opposing upper guide plates are hinged to the lower ends of the flow pipe and the outer ends extend to the left and right sides to form a funnel-shaped flow guiding screening chamber. The upper end of the front baffle plate is hinged to the left end of the horizontal sorting chamber and the rear baffle plate is hinged to the right end of the horizontal sorting chamber, and the lower ends of both are exposed outside the horizontal sorting chamber.
[0006] The first belt conveyor is located at the left end of the lower port of the horizontal sorting chamber and its discharge head extends into the lower end of the guide screening chamber inside the horizontal sorting chamber. The end of the front baffle can be vertically attached to the first conveyor belt of the first belt conveyor. The mixed material pushes the front baffle to rotate clockwise and enter the guide screening chamber.
[0007] The second belt conveyor is located at the lower right end of the lower port of the horizontal sorting chamber, and its feed head is located directly below the discharge head of the first belt conveyor. The end of the rear baffle plate can be vertically attached to the second conveyor belt of the second belt conveyor. When the heavy material pushes the end of the rear baffle plate to rotate clockwise and be carried out by the second conveyor belt.
[0008] The air outlet of the blower in the air supply unit is connected to the lower end of the directional air duct. The upper end of the directional air duct is located between the second conveyor belt and the first conveyor belt and is connected to the speed-increasing air nozzle. The speed-increasing air nozzle is inclined and located below the discharge head of the first belt conveyor, and its air outlet is directly facing the parabolic direction of the discharge head and the guide screening chamber. The high-speed airflow blows the light materials and dust of the falling mixture upward into the guide screening chamber to form a mixed airflow, and the heavy materials fall into the second conveyor belt.
[0009] The feed inlet of the cyclone separator is connected to the upper end of the guide pipe, and the exhaust port at the upper end of the pipe is connected to the dust collector. Light substances in the mixed airflow are discharged from the lower end of the cyclone separator, and dust-laden gas enters the dust collector.
[0010] The dust collector discharges dust from its lower port and connects to the clean exhaust section at its upper port to discharge clean air.
[0011] In some embodiments, the middle of the upper guide plate is an arc-shaped plate with both ends curving upwards, and the inner tangent panel of the arc-shaped plate is hinged to the lower end of the drainage pipe; the outer tangent panel of the arc-shaped plate on the right end is inclined upwards and approaches the horizontal sorting chamber, and the outer tangent panel and the front baffle plate form the front circulation settling chamber.
[0012] In some embodiments, the rectangular array of the front baffle plate at the right end is provided with several side air nozzles, which allow light materials and dust in the front circulation settling chamber to flow back to the guide screening chamber.
[0013] The rectangular array of rear baffles on the left end is equipped with several side air nozzles, which allow light materials and dust from the second conveyor belt to flow back to the guide screening chamber.
[0014] In some implementations, the rear baffle is connected to the right wall of the horizontal sorting chamber via a height-floating buffer; the front baffle is connected to the left wall of the horizontal sorting chamber via a height-floating buffer; and the two arc-shaped plates are connected to the upper wall of the horizontal sorting chamber via height-floating buffers.
[0015] In some implementations, the height-floating buffer is any one of a floating cylinder, a spring column, and a servo electric cylinder.
[0016] In some embodiments, the speed-increasing nozzle is a flat nozzle with a rectangular cross-section, the cross-section of which gradually decreases from bottom to top, and the tilt direction of the flat nozzle is tangential to the roller of the discharge head.
[0017] The lower and upper ends are connected by an arc-shaped bend. The lower end is inclined outside the feed head of the second belt conveyor; the upper end is parallel to the feed head of the second belt conveyor and parallel to the discharge head of the first belt conveyor.
[0018] In some implementations, a CCD high-definition acquisition camera electrically connected to the control module is also provided at the lower left end of the horizontal sorting chamber. The CCD high-definition acquisition camera captures the quantity and frequency of the thin film material in the bulk material. When the quantity and frequency of the thin film material are abnormal, the control module controls the fan speed to increase, while reducing the feeding speed of the first belt conveyor.
[0019] In some embodiments, a blockage relief assembly is provided at the connection between the first air duct and the drainage pipe; the blockage relief plate of the blockage relief assembly has the same outline as the upper wall of the first air duct, and the telescopic rod of the blockage relief cylinder passes through the blockage relief plate connected to the first air duct, and the blockage relief cylinder periodically extends and retracts to cause the material at the bend to fall.
[0020] In some embodiments, the unblocking cylinder is fixed on the cylinder seat, which is connected to the first air duct or the horizontal sorting chamber. Two vertical guide rods are provided between the top plate of the cylinder seat and the unblocking plate. The unblocking plate is annular and has cutting blades on both the inner wall and the outer wall at the lower end.
[0021] Alternatively, the upper end of the unblocking plate may have a rubber elastic layer.
[0022] In some embodiments, the lower port of the horizontal sorting chamber forms a rectangular feed port on the right side and a discharge port on the left side. The first belt conveyor is located below the feed port and extends into the guide screening chamber; the second belt conveyor is located below the discharge port. The horizontal sorting chamber, the first belt conveyor, and the second belt conveyor are inclined at the same angle.
[0023] Alternatively, the clean emission section may consist of a tall chimney;
[0024] Alternatively, the first and second conveyor belts may be skirted belts, or the conveyor frames on both sides of the conveyor belts may be equipped with limit baffles;
[0025] Alternatively, the drainage tube may be a rectangular tube.
[0026] This new type of horizontal air classifier adopts a special configuration of a horizontal sorting body, a first belt conveyor, a second belt conveyor, and an air supply unit. This effectively achieves high-precision separation of heavy materials, while a cyclone separator effectively removes light materials, and a dust collector effectively removes dust. Clean gas is discharged into the air, resulting in high purity materials at each stage that can be directly utilized. Its advantages are: First, the process is simple; a single station combining a cyclone separator and a dust collector completes the separation of three stages of material. It only requires one infeed belt conveyor and one outlet belt conveyor—two intermediate transfer devices. The equipment is simple, occupies a small area, consumes little energy, and has low cost. Second, the speed-increasing air nozzles in the feeding unit are tilted below the discharge head of the first belt conveyor, with their outlets directly facing the parabolic direction of the discharge head and the guiding screening chamber. This effectively separates light materials and thin film materials, preventing thin film materials from entering the subsequent processing of heavy materials. The overall production line operates stably, effectively reducing maintenance costs and equipment downtime, improving sorting efficiency, and ensuring high purity of materials at each stage of sorting. First, it is pure, which is beneficial for subsequent processing and reuse; second, it is equipped with a diversion pipe, and the upper guide plate at the lower end can change size with the wind force, and the trumpet-shaped diversion screening chamber also changes accordingly. Therefore, it can effectively guide light materials and dust into the diversion pipe to form effective and rapid separation. At the same time, the front and rear baffles prevent material dispersion and overflow. The material in the front baffle can fall into the belt conveyor for re-sorting; third, it can be set up to directly sort in the narrow space of the belt discharge and feed, with a compact overall structure and effectively improve sorting efficiency; fourth, it also has a good unblocking and guiding effect; fifth, it can adjust the sorting speed at any time to ensure the best material sorting accuracy.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.
[0043] Figures 1 to 7 The figure schematically illustrates a novel horizontal air separator according to one embodiment of the present invention. As shown, the novel horizontal air separator includes: a horizontal sorting body 1, a first belt conveyor 2, a second belt conveyor 3, an air supply unit 4, a cyclone separator 5, and a dust collector 6;
[0044] The horizontal sorting body 1 includes a horizontal sorting chamber 10, two upper guide plates 11, a front baffle plate 12, and a rear baffle plate 13. The horizontal sorting chamber 10 is hollow inside and open at the bottom. A flow pipe 14 is fixedly connected to the middle of the upper end of the horizontal sorting chamber 10. The inner ends of the two opposing upper guide plates 11 are hinged to the lower ends of the flow pipe 14, and the outer ends extend to the left and right sides to form a trumpet-shaped flow guiding screening chamber 100. The upper end of the front baffle plate 12 is hinged to the left end of the horizontal sorting chamber 10, and the rear baffle plate 13 is hinged to the right end of the horizontal sorting chamber 10, with the lower ends of both protruding from the lower port of the horizontal sorting chamber 10.
[0045] The first belt conveyor 2 is located at the left end of the lower port of the horizontal sorting chamber 10 and its discharge head 20 extends into the lower end of the guide screening chamber 100 inside the horizontal sorting chamber 10. The end of the front baffle plate 12 can be vertically attached to the first conveyor belt 21 of the first belt conveyor 2. The mixed material pushes the front baffle plate 12 to rotate clockwise and enter the guide screening chamber 100.
[0046] The second belt conveyor 3 is located at the lower right end of the lower port of the horizontal sorting chamber 10, and its feed head 30 is located directly below the discharge head 20 of the first belt conveyor 2. The end of the rear baffle plate 13 can be vertically attached to the second conveyor belt 31 of the second belt conveyor 3. The heavy material pushes the end of the rear baffle plate 13 to rotate clockwise and be carried out by the second conveyor belt 31.
[0047] The air supply unit 4 includes a fan 41, a directional air duct 42, and a speed-increasing nozzle 43. The air outlet of the fan 41 is connected to the lower end 421 of the directional air duct 42. The upper end 422 of the directional air duct 42 is located between the second conveyor belt 31 and the first conveyor belt 21. The upper end 422 is connected to the inclined speed-increasing nozzle 43. The speed-increasing nozzle 43 is inclined and located below the discharge head 20 of the first belt conveyor 2, and its air outlet is directly facing the parabolic direction of the discharge head 20 and the guide screening chamber 100. The high-speed airflow blows the light materials and dust of the falling mixture upward into the guide screening chamber 100 to form a mixed airflow. The heavy materials fall into the second conveyor belt 31.
[0048] The feed inlet of the cyclone separator 5 is connected to the upper port of the diversion pipe 14 and the exhaust port at its upper end is connected to the dust collector 6. The cyclone separator 5 separates the light substances in the mixed airflow and discharges them from the lower outlet. The remaining dust-laden gas enters the dust collector 6 through the exhaust port.
[0049] The dust collector 6 has at least one dust outlet at its lower end and a clean gas outlet at its upper end connected to the clean emission section 7, with the high port of the clean emission section 7 discharging clean air.
[0050] This new type of horizontal air separator employs a unique configuration of a horizontal sorting main body 1, a first belt conveyor 2, a second belt conveyor 3, and an air supply unit 4. This effectively achieves high-precision separation of heavy materials, while a cyclone separator 5 effectively removes light materials, and a dust collector 6 effectively removes dust. Clean gas is discharged into the air, resulting in high purity of materials at each stage, which can be directly utilized. Its advantages are: First, the process is simple; a single station combining a cyclone separator and a dust collector completes the separation of three stages of materials. It requires only one infeed belt conveyor and one outlet belt conveyor—two intermediate transfer devices. The equipment is simple, occupies a small area, consumes little energy, and has low cost. Second, the speed-increasing nozzle 43 of the feeding unit 4 is inclined and located below the outlet head 20 of the first belt conveyor 2, with its outlet directly facing the parabolic direction of the outlet head 20 and the guiding screening chamber 100. This effectively separates light materials and thin film materials, preventing thin film materials from entering the subsequent processing of heavy materials. The overall production line operates stably, effectively reducing maintenance costs and equipment costs. First, the system improves sorting efficiency, and the materials sorted at each stage are pure, which is beneficial for subsequent processing and reuse. Second, the system is equipped with a guide pipe 14, and the upper guide plate 11 at the lower end can change size with the wind force. The trumpet-shaped guide screening chamber 100 also changes accordingly. Therefore, it can effectively guide light materials and dust into the guide pipe 14 to form effective and rapid separation. At the same time, the front baffle plate 12 and the rear baffle plate 13 prevent material dispersion and overflow. The material in the front baffle plate 12 can fall into the belt conveyor for re-sorting. Third, the system can directly sort in the narrow space of the belt discharge and feed. The overall structure is compact and effectively improves sorting efficiency.
[0051] Furthermore, the upper guide plate 11 has an arc-shaped plate 110 with both ends bent upwards in the middle. The inner tangent panel 111, integrally connected to the arc-shaped plate 110, is hinged to the lower end of the guide pipe 14. The outer tangent panel 112, integrally connected to the right arc-shaped plate 110, is inclined upwards and approaches the horizontal sorting chamber 10. The outer tangent panel 112 and the front baffle plate 12 form a front circulation settling chamber 101, where light materials and dust fall onto the first conveyor belt 21 for circulating screening. The beneficial effects are: the arc-shaped plate 110 has a good guiding effect and low resistance, and the front circulation settling chamber 101 can improve the sorting efficiency.
[0052] Preferably, the front baffle plate 12 at the right end is also provided with a rectangular array of several side air nozzles 16, which allow light materials and dust in the front circulation settling chamber 101 to flow back to the guide screening chamber 100.
[0053] The rectangular array of the rear baffle plate 13 at the left end is equipped with several side air nozzles 16. The side air nozzles 16 cause the light materials and dust on the second conveyor belt 31 to flow back to the guide screening chamber 100. Its beneficial effects are: setting the side air nozzles 16 can effectively remove thin film material from entering the heavy material, and can also prevent multiple cycles of sorting caused by the material returning to the front, thereby improving the sorting efficiency.
[0054] Furthermore, the rear side of the rear baffle 13 is connected to the right wall of the horizontal sorting chamber 10 via a height-floating buffer 8; the front side of the front baffle 12 is connected to the left wall of the horizontal sorting chamber 10 via a height-floating buffer 8; and the upper parts of the two arc-shaped plates 110 are connected to the upper wall of the horizontal sorting chamber 10 via height-floating buffer 8. Preferably, the height-floating buffer 8 is any one of a floating cylinder, a spring column, and a servo electric cylinder. Its beneficial effect is that the height-floating buffer 8 ensures the positional accuracy of the rear baffle 13, the front baffle 12, and the front baffle 12, constantly matching the sorting volume, and ensuring optimal sorting efficiency and accuracy.
[0055] Furthermore, the speed-increasing nozzle 43 is a flat nozzle with a rectangular cross-section. The cross-section of the flat nozzle gradually decreases from bottom to top, and the tilt direction of the flat nozzle 43 is tangential to the roller of the discharge head 20. Its advantages are: this structure is compact and small in size, facilitating equipment layout, while providing high air velocity, effectively improving sorting power.
[0056] Preferably, the lower end 421 and the upper end 422 of the steering duct 42 are connected by an arc bend. The lower end 421 is inclinedly disposed outside the feed head of the second belt conveyor 3; the upper end 422 is disposed parallel to the feed head of the second belt conveyor 3 and parallel to the discharge head 20 of the first belt conveyor 2. The beneficial effect is that this arrangement can effectively reduce the size of the equipment.
[0057] Furthermore, a CCD high-definition acquisition camera 15, electrically connected to the control module, is also installed at the lower left end of the horizontal sorting chamber 10. The CCD high-definition acquisition camera 15 captures the quantity and frequency of thin film material in the bulk material. When the quantity and frequency of thin film material are abnormal, the control module controls the fan 41 to increase its speed while simultaneously reducing the feeding speed of the first belt conveyor 2. The beneficial effect is that this setting further improves the purity of heavy material sorting and prevents thin film material from mixing into heavy material.
[0058] Furthermore, at the connection between the first air duct 51 and the diversion pipe 14, the first air duct 51 is equipped with a blockage-removing component 9. The blockage-removing component 9 includes a blockage-removing cylinder 91 and a blockage-removing plate 92. The blockage-removing plate 92 has the same outline as the upper wall of the first air duct 51. The blockage-removing cylinder 91 is vertically connected to the first air duct 51 or the horizontal sorting chamber 10. The telescopic rod passes through the first air duct 51 with a small gap and connects to the blockage-removing plate 92. The blockage-removing cylinder 91 periodically extends and retracts to cause the material at the bend to fall. Its beneficial effects are: this setting ensures long-term use without blockage, while the structure is compact and does not affect the internal air separation channel. During sorting, the blockage-removing plate 92 is subjected to outward lateral pressure, tightly adhering to the pipe wall without air loss, and the blockage-removing effect is good.
[0059] Preferably, the unblocking cylinder 91 is fixedly connected to the cylinder seat 90, which is connected to the first air duct 51 or the horizontal sorting chamber 10. Two vertical guide rods 94 are provided between the top plate 901 of the cylinder seat 90 and the unblocking plate 92. The beneficial effect is that this setting ensures good unblocking accuracy and prevents deviation, jamming and blockage.
[0060] Preferably, the unblocking plate 92 has an annular structure, and both the inner wall and the outer wall at the lower end of the unblocking plate 92 are provided with cutting edges. Its beneficial effect is that this design further improves the unblocking efficiency.
[0061] The unblocking plate 92 can also have a built-in scissor cutter. The scissor cutter rotates and crushes the film, which further facilitates unblocking.
[0062] Preferably, the upper end of the unblocking plate 92 is also provided with a rubber elastic layer 93. The beneficial effect is that this setting further ensures airtightness, while protecting the pipe wall and the unblocking plate 92 from deformation during long-term use.
[0063] Furthermore, the lower port of the horizontal sorting chamber 10 forms a rectangular feed port 102 on the right side and a discharge port 103 on the left side of the lower port. The first belt conveyor 2 is located below the feed port 102 and extends into the guide screening chamber 100; the second belt conveyor 3 is located below the discharge port 103, and the first belt conveyor 2 is arranged parallel to the second belt conveyor 3.
[0064] The horizontal sorting chamber 10, the first belt conveyor 2, and the second belt conveyor 3 are inclined at the same angle; the inclination angle is 5°-30°; preferably 15°. Its beneficial effect is that this setting can quickly enter the sorting chamber and receive heavy materials at the first time without any spillage of heavy materials.
[0065] Preferably, the clean emission section 7 is a tall chimney.
[0066] Preferably, the first conveyor belt 21 and the second conveyor belt 31 are skirted belts or the conveyor frames on both sides of the conveyor belts are equipped with limiting baffles. The beneficial effect is that this setting prevents material from overflowing.
[0067] Preferably, the feed inlet of the cyclone separator 5 is connected to the upper port of the guide pipe 14 through the first air duct 51.
[0068] The exhaust port at the upper end of the cyclone separator 5 is connected to the dust collector 6 through the second air duct 52, and the dust collector 6 is connected to the clean discharge section 7 through the third air duct 61.
[0069] The cyclone separator 5 has a third conveyor belt or mobile trolley at its lower light material outlet; the dust collector 6 has at least one dust outlet at its lower end, and the dust outlet is equipped with a stopcock valve and a fourth conveyor belt or mobile trolley is located below it. The effect is that this setup further improves automation.
[0070] Preferably, the horizontal sorting body 1, the first belt conveyor 2, the second belt conveyor 3, the air supply unit 4, the cyclone separator 5, and the dust collector 6 are all fixedly connected to the same frame, and the frame is equipped with guardrails. Its advantages are: the structure is simple and the size is small.
