[0039] Figure 1 A schematic diagram of a wind sorting machine 1 according to an embodiment of the present application is demonstrated. In some embodiments, the wind sorting machine 1 is configured to receive materials, including but not limited to plastic bottle flakes, and also includes labels and dust. In some embodiments, the wind sorting machine 1 is a multi-channel wind sorting machine, which screens and filters materials by wind power to collect plastic bottle flakes in the materials and filter unnecessary labels, dust and other substances. Specifically, the wind sorting machine 1 utilizes the difference in aerodynamic characteristics (drift coefficient) of bottle flakes and labels mixed therein, and separates light impurities such as labels in PET bottle flakes through negative pressure air flow. In some embodiments, after the wind sorting machine 1 collects the plastic bottle flakes, the plastic bottle flakes are sent to the next process (such as cleaning, drying, etc.), and finally the plastic bottle flakes are recycled and reused. In some embodiments, the wind sorting machine 1 includes a material mixing section 11, a silo 112', a sorting section 12, a collection platform 13 and a fan system 14. In some embodiments, the wind classifier 1 may further include a diaphragm 15 and a dust bag 16 .

[0040] Figure 2 The enlarged schematic diagram of the material mixing unit 11, the material bin 112', the sorting unit 12 and the material collecting platform 13 according to an embodiment of the present application is demonstrated. In some embodiments, the material mixing unit 11, the material bin 112' and the sorting unit 12 are arranged on the material collecting platform 13, the material mixing unit 11, the material bin 112', the sorting unit 12 and the material collecting platform 13 are coaxially arranged, and the structures of the material mixing unit 11, the material bin 112', the sorting unit 12 and the material collecting platform 13 are centrally symmetrical.

[0041] In some embodiments, the material mixing unit 11 includes a material mixing barrel 110 and a material mixing hopper 111. In other embodiments, the material mixing unit 11 may further include a reducer (not shown). In some embodiments, the material mixing barrel 110 is roughly cylindrical and is arranged above the material mixing unit 11, and the material mixing hopper 111 is arranged inside the material mixing barrel 110.

The appearance of the silo 112' is a symmetrical conical structure, and the material mixing unit 11 is arranged directly above the center of the silo 112'. A plurality of discharge ports C11 are evenly distributed below the silo 112'.

[0042] The interior of the silo 112 ′ generally presents a downwardly inclined chamber structure. After the materials enter the silo 112 ′, they enter the sorting section 12 through various discharge ports C11 under the action of gravity.

[0043] In some embodiments, the number of the outlets C11 is eight. However, this is not a limitation of the present application. In other embodiments, the number of the outlets C11 may be more or less than eight.

[0044] The detailed structure of the material mixing barrel 110 can be referred to Figure 3 , Figure 3 The perspective view of the material mixing unit 11 according to an embodiment of the present application is demonstrated. The connecting shaft Z111 of the material mixing hopper 111 is set on the central axis of the material mixing barrel 110. One end of the shaft Z111 is connected to the motor MO, and the other end is connected to multiple support shafts J111. The multiple support shafts J111 are connected to the inside of the discharge hopper D111 to play a supporting role and at the same time have the function of breaking up the materials to avoid the materials from gathering and increasing the difficulty of sorting. The support shafts J111 are evenly arranged in the discharge hopper D111 and extend along the radial direction of the material mixing barrel 110. The lower part of the discharge hopper D111 is connected to the silo 112', and the discharge hopper D111 rotates under the drive of the motor MO through the support shaft J111 and the connecting shaft Z111. After the materials enter the material mixing barrel 110, they are broken up by the support shaft J111 and enter the silo 112' roughly evenly through the rotation of the discharge hopper D111. In some embodiments, the number of the support shafts J111 is three, however, this is not a limitation of the present application. In other embodiments, the number of the support shafts J111 may be more or less than three.

[0045] Reference again Figure 2, the sorting section 12 is arranged around the material mixing section 11 and the silo 112'. The sorting section 12 includes a plurality of feeding units 120 and a plurality of sorting chambers 121, wherein each feeding unit 120 is correspondingly connected to each sorting chamber 121, and each feeding unit 120 is also correspondingly connected to the corresponding discharge port C11. In other words, the sorting section 12 also includes eight feeding units 120 and eight sorting chambers 121, which are evenly distributed around the silo 112'. However, for the sake of simplicity and convenience of explanation, Figure 2 Only one of the dosing units 120 and one of the sorting chambers 121 are depicted.

[0046] For detailed structure of the feeding unit 120, please refer to Figure 4A and Figure 4B , Figure 4A and Figure 4B The three-dimensional view and the side view of the feeding unit 120 according to an embodiment of the present application are respectively demonstrated. In some embodiments, the feeding unit 120 includes a feeding trough 21 and an electromagnetic vibrator 22. The inlet E120 of the feeding unit 120 is opened on the upper surface of the feeding trough 21, and the outlet C120 of the feeding unit 120 is opened on the side surface of the feeding trough 21, wherein the inlet E120 is connected with the outlet C11 of the material mixing part 11, and the outlet C120 is connected with the inlet of the sorting chamber 121. The trough body of the feeding trough 21 generally presents a structure inclined downward, so that after the material enters the feeding trough 21 through the outlet C11 and the inlet E120, it moves to the outlet C120 in the feeding trough 21 under the action of the electromagnetic vibrator 22, and then enters the sorting chamber 121 through the outlet C120. In some embodiments, the inclination angle of the feeding trough 21 is approximately in the range of 5 degrees to 10 degrees. Preferably, the inclination angle of the feeding trough 21 is 8 degrees.

[0047] In some embodiments, the feed trough 21, when viewed from a top or bottom angle, generally presents a trapezoidal structure with one end wider and the other end narrower. Specifically, the width of the feed trough 21 near the inlet E120 (end A in the figure) is smaller than the width of the trough near the outlet C120 (end B in the figure). In this arrangement, the electromagnetic vibrator 22 can be used to disperse the materials as they move forward in the feed trough 21, so as to avoid the materials from gathering and increasing the difficulty of sorting. In some embodiments, the width of the feed trough 21 near the inlet E120 (end A in the figure) is approximately 300 mm, and the width of the trough near the outlet C120 (end B in the figure) is approximately 600 mm.

[0048] In some embodiments, the electromagnetic vibrator 22 is configured to vibrate the feed trough 21, so that the material in the feed trough 21 is not only moved forward by the action of gravity, but also by the action of vibration, and the material is more dispersed under the action of vibration, so as to avoid the material from gathering and increasing the difficulty of sorting. The connection between the electromagnetic vibrator 22 and the feed trough 21 can be achieved by means of screws, buckles, magnetic buckles, magnetic attraction, etc., which is not a limitation of the present application. In some embodiments, the electromagnetic vibrator 22 is arranged close to the lower surface of the feed trough 21. The electromagnetic vibrator 22 has an adjustment unit 220, and the inclination angle of the electromagnetic vibrator 22 can be adjusted by the adjustment unit 220, thereby adjusting the inclination angle of the feed trough 21. In some embodiments, the adjustment unit 220 can achieve angle adjustment by means of screws, buckles, etc.

[0049] Also refer to Figure 2 and Figure 5 , Figure 5 A schematic diagram of a sorting chamber 121 according to an embodiment of the present application is shown. In some embodiments, a plurality of collecting ports E13 are provided on the collecting platform 13, and the number and position of the collecting ports E13 correspond to the number and position of the feeding unit 120 and the sorting chamber 121. In other words, the collecting platform 13 includes eight collecting ports E13. The lower end of the sorting chamber 121 is connected to the corresponding collecting port E13, and the upper end of the sorting chamber 121 is connected to the centrifugal fan 141 (shown in FIG. 14 ) of the fan system 14. Figure 1 ) connected.

[0050] The centrifugal fan 141 generates negative pressure and upward airflow in the sorting chamber 121, so as to screen the materials in the sorting chamber 121 by wind force. In some embodiments, the power of the centrifugal fan 141 is 15KW, the wind force generated is about 12000-15000 cubic meters / hour, and the wind speed generated in the sorting chamber 121 is about 1-4 meters / second. As shown in the figure, the sorting chamber 121 is vertically arranged on the collection platform 13, so that when the materials are in the sorting chamber 121, the heavier materials such as plastic bottle pieces can fall into the collection platform 13 by gravity, and the lighter labels or dust in the materials will be sucked into the diaphragm 15 and the dust bag 16 by the upward airflow, thereby completing the screening of the materials. The applicant has found through experiments that the separation effect of the materials is more than 90%.

[0051] In some embodiments, the width of the upper end (end C in the figure) of each sorting chamber 121 is smaller than the width of the lower end (end D in the figure), and the airflow velocity near the upper end of the sorting chamber 121 is greater than the airflow velocity near the lower end of the sorting chamber 121. In some embodiments, the cross-sectional area of ​​the upper end of each sorting chamber 121 is circular to facilitate connection to the fan system, and the cross-sectional area of ​​the lower end of each sorting chamber 121 is rectangular to connect to the aggregate port E13. The applicant has found through experiments that Figure 2 The design of the feeding unit 120 and the sorting chamber 121 shown in the embodiment can achieve a separation effect of more than 90%.

[0052] Figure 6 The enlarged schematic diagram of the material-scraping part 11', the silo 112', the sorting part 12' and the material-collecting platform 13' according to another embodiment of the present application is demonstrated. In some embodiments, the material-scraping part 11', the silo 112' and the sorting part 12' are arranged on the material-collecting platform 13', the material-scraping part 11', the silo 112', the sorting part 12' and the material-collecting platform 13' are arranged coaxially, and the structures of the material-scraping part 11', the sorting part 12' and the material-collecting platform 13' are centrally symmetrical.

[0053] In some embodiments, the material mixing unit 11' includes a material mixing cylinder 110 and a material mixing hopper 111, wherein the material mixing cylinder 110, the material mixing hopper 111 and Figure 2 The same as the embodiments, the details are omitted here to save space. Figure 6 In the embodiment, the outside of the silo 112' is a symmetrical polygonal straight tube structure with equal width from top to bottom, which increases the silo volume and makes it less likely to get blocked. The discharge ports C11' are evenly distributed below the silo 112'. After the materials enter the silo 112', they enter the sorting section 12' through the discharge ports C11' under the action of gravity.

[0054] The sorting section 12' is arranged around the silo 112'. The sorting section 12' includes a plurality of feeding units 120' and a plurality of sorting chambers 121', wherein each feeding unit 120' is correspondingly connected to each sorting chamber 121', and each feeding unit 120' is also correspondingly connected to a corresponding discharge port C11'. In other words, the sorting section 12' also includes eight feeding units 120' and eight sorting chambers 121', which are evenly distributed around the silo 112'. However, for the sake of simplicity and convenience of explanation, Figure 6 Only one of the dosing units 12 ′ 0 and one of the sorting chambers 121 ′ are depicted.

[0055] In some embodiments, the feeding unit 120' includes a flexible connection unit 20', a feeding trough 21', an electromagnetic vibrator 22' and a chute 23'. Fig. 7A , Figure 7B and 7C ,in Fig. 7A and Figure 7B The three-dimensional view and the side view of the flexible connection unit 20', the feed trough 21' and the electromagnetic vibrator 22' according to an embodiment of the present application are respectively demonstrated. Figure 7CDemonstrating a stereoscopic view of the chute 23' according to an embodiment of the present application. The inlet E120' of the feeding unit 120' is opened at the upper end of the flexible connection unit 20', and the outlet C120' of the feeding unit 120' is opened at a port of the chute 23' away from the feeding trough 21', wherein the inlet E120' is connected to the discharge port C11', and the outlet C120' is connected to the inlet. Soft connection unit 20' Extending from entrance E120' down to Feed trough 21', The body of the feed trough 21 ′ horizontally extends from the soft connection unit 20 ′ and is connected to the inlet D23 of the chute 23 ′, and the body of the chute 23 ′ obliquely extends downward from the port D23 and is connected to the sorting chamber 121 ′.

[0056] In some embodiments, when the feed trough 21' is viewed from a top or bottom angle, it generally presents a trapezoidal structure with one end wider and the other end narrower. Specifically, the width of the feed trough 21' near the end of the soft connection unit 20' (end A in the figure) is smaller than the width of the trough near the end of the chute 23' (end B in the figure). With this arrangement, the materials can be more dispersed during the movement of the feed trough 21', avoiding the gathering of materials and increasing the difficulty of sorting. In some embodiments, the width of the feed trough 21' near the end of the inlet E120' (end A in the figure) is approximately 300 mm, and the width of the trough near the end of the connection trough 23' (end B in the figure) is approximately 600 mm.

[0057] In some embodiments, the electromagnetic vibrator 22' is configured to vibrate the feed trough 21', so that the material is subjected to the vibration in the feed trough 21' and moves forward, and under the action of the vibration, the material is more dispersed to avoid the material gathering and increasing the difficulty of sorting. The connection between the electromagnetic vibrator 22' and the feed trough 21' can be achieved by screws, buckles, magnetic buckles, magnetic attraction, etc., which is not a limitation of the present application. In some embodiments, the electromagnetic vibrator 22' is set close to the lower surface of the feed trough 21'.

[0058] After the material enters the soft connection unit 20' and the feed trough 21' through the discharge port C11' and the inlet E120', it moves toward the chute 23' in the feed trough 21' with vibration, and the material is more dispersed during the movement. The material falls in the chute 23' by gravity. A plurality of air inlet holes H23' are provided on the lower surface of the chute 23', and air is introduced from the air inlet holes H23' so that the material in the chute 23' can be preliminarily screened. Specifically, refer to Figure 8Schematic diagram, when the materials pass through the chute 23', the lighter labels, dust and other substances will be blown away from the bottom of the chute 23' by the wind entering from the air inlet H23', while the heavier bottle pieces will remain at the bottom of the chute, so as to achieve the effect of preliminary screening. The labels, dust and other substances blown away from the bottom of the chute will be more easily drawn upward by the negative pressure generated by the centrifugal fan 141 in the sorting chamber 121', forming a Figure 8 The track G shown in FIG. The other materials that have not been blown off the bottom of the chute 23' are screened for the second time at the connection H between the chute 23' and the sorting chamber 121' by the negative pressure in the sorting chamber 121'.

[0059] Compared to Figure 2 Example, Figure 6 In the embodiment shown, due to the addition of the chute 23', the sorting chamber 121' is disposed further outward, and accordingly, the volume of the material collection platform 13' is also enlarged, thereby increasing the capacity.

[0060] Also refer to Figure 6 and Fig. 9 , Fig. 9 A schematic diagram of a sorting chamber 121' according to an embodiment of the present application is shown. In some embodiments, a plurality of collecting ports E13' are provided on the collecting platform 13', and the number and position of the collecting ports E13' correspond to the number and position of the feeding unit 120' and the sorting chamber 121'. In other words, the collecting platform 13' includes eight collecting ports E13'. The lower end of the sorting chamber 121' is connected to the corresponding collecting port E13', and the upper end of the sorting chamber 121' is connected to the centrifugal fan 141 (shown in FIG. 14 ) of the fan system 14. Figure 1 ) connected.

[0061] The centrifugal fan 141 generates negative pressure and upward airflow in the sorting chamber 121', so as to screen the materials in the sorting chamber 121' by wind force. The sorting chamber 121' is vertically arranged on the material collecting platform 13', so that when the materials are in the sorting chamber 121', the heavier materials such as plastic bottle flakes can fall into the material collecting platform 13' by gravity, and the lighter labels or dust in the materials will be sucked into the shackle 15 and the dust bag 16 by the upward airflow, thereby completing the screening of the materials. In some embodiments, the width of the upper end (C end shown in the figure) of each sorting chamber 121' is the same as the width of the lower end (D end shown in the figure), so that the overall airflow speed in the sorting chamber 121' is roughly the same, so as to prevent the strong airflow at the upper end of the sorting chamber 121' from accidentally sucking away the bottle flakes. In some embodiments, the cross-sectional area of ​​the upper end of each sorting chamber 121' is circular to facilitate connection to the fan system, and the cross-sectional area of ​​the lower end of each sorting chamber 121' is rectangular to connect to the collection port E13'. Figure 6The design of the feeding unit 120' and the sorting chamber 121' shown in the embodiment can achieve a separation effect of more than 99%. In addition, the higher the analysis rate, the shorter the time for subsequent manual operations, thus significantly increasing the production capacity.

[0062] Reference again Figure 1 The fan system 14 includes a centrifugal fan 141 and an air duct assembly 142. The air duct assembly 142 includes a main air duct a142, a collecting air duct b142, and a plurality of auxiliary air ducts c142. Each of the plurality of auxiliary air ducts c142 is connected between the corresponding sorting chamber 121 and the collecting air duct b142, and the main air duct a142 is connected between the collecting air duct b142 and the centrifugal fan 141. In some embodiments, the diameter of one end of each auxiliary air duct c142 close to the sorting chamber 121 is larger than the diameter of the end away from the sorting chamber 121, so that the air flow speed in the auxiliary air duct c142 is faster as it is away from the sorting chamber 121, which is conducive to extracting labels and dust through air flow. The diameter of the main air duct a142 at one end close to the collecting air duct b142 is larger than the diameter of the end away from the collecting air duct b142, so that the air flow speed in the main air duct a142 is faster as it moves away from the concentrating cavity b142, which is also beneficial for removing labels and dust through the airflow.

[0063] The light materials such as labels are sucked away by the centrifugal fan 141 and enter the diaphragm 15 from the main air duct a142, and finally fall into the space bag, and the space bag is transported by the personnel through the transportation tool. Other materials such as dust are sent to the dust bag 16 after most of the wind pressure is removed by the diaphragm 15 to keep it clean.

[0064] It should be noted that the wind separator 1 proposed in the present application may also include other components. For example, the wind separator 1 also includes a feed screw 30 (shown in FIG. Figure 1 ), the feeding screw 30 is connected to the feeding port E11 of the material mixing part 11, so that the front-end equipment can pour the materials into the material for material sorting. This application specification focuses on the part related to the invention spirit of this application, and other components included in the wind separator 1 are omitted here to save space.

For example, when used in conjunction with a numerical value, the terms may refer to a range of variation of less than or equal to ±10% of the numerical value, for example, less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, two values ​​may be considered "substantially" or "approximately" the same if the difference between them is less than or equal to ±10% of the average of the values ​​(e.g., less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%). For example, "substantially" parallel can refer to an angular variation range of less than or equal to ±10° relative to 0°, for example, less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°. For example, "substantially" vertical can refer to an angular variation range of less than or equal to ±10° relative to 90°, for example, less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°.

[0067] For example, two surfaces may be considered coplanar or substantially coplanar if the displacement between the two surfaces is equal to or less than 5 μm, equal to or less than 2 μm, equal to or less than 1 μm, or equal to or less than 0.5 μm. A surface may be considered planar or substantially planar if the displacement between any two points on the surface relative to the plane is equal to or less than 5 μm, equal to or less than 2 μm, equal to or less than 1 μm, or equal to or less than 0.5 μm.
