Description

Technical Field

[0001] The present invention relates to the technical field of garbage separation, and more specifically to a garbage air separation device. Background Art

[0002] In the solid waste recycling process, the solid waste is generally separated by air separation according to its density (i.e. light and heavy). However, this solution requires first using a conveyor line to transport the solid waste to the inlet of the air separation box, and then using an air separation mechanism in the air separation box to output the solid waste to the light and heavy outlets respectively; finally, additional conveyor lines are set up at the light and heavy outlets for coordination.

[0003] In order to achieve continuous separation of light and heavy garbage on the conveyor line, the inventor tried to set up a square tube, the conveyor line is set at the bottom of the square tube, the square tube has opposite first side walls and opposite second side walls, the conveyor line passes through the gaps of the two first side walls in sequence, and a light outlet is set at the top of the square tube. There is an airflow inside the square tube that is inclined downward and sprayed toward the second side wall. Under the action of the Coanda effect (also known as the Coanda effect), the airflow flows downward along the surface of the second side wall until it contacts the conveyor line; at this time, the gas flows upward from the middle of the conveyor line and entrains the light garbage upward, and finally the airflow carries the light garbage out from the light outlet.

[0004] However, in the above technical solution, the heavy garbage on the conveyor line is easily entrained in the light garbage, or the heavy garbage is pressed on the surface of the light garbage. If the airflow intensity is too large, the heavy garbage entrained in the light garbage will be discharged from the upper light outlet. If the airflow intensity is too small, part of the light garbage entrained in the heavy garbage will not be able to rise, and then this part of the light garbage will be discharged from the heavy discharge port.

[0005] That is, the above-mentioned wind separation device that only relies on the Coanda effect is difficult to achieve a better sorting effect due to the mutual entanglement of heavy garbage and light garbage. Summary of the invention

[0006] The purpose of the present invention is to overcome or at least alleviate the deficiencies of the above-mentioned prior art, so as to solve at least one of the above-mentioned technical problems.

[0007] In order to achieve the above-mentioned purpose, the present invention provides a garbage air separation device, including a vertical square cylinder and a conveying line conveying along a horizontal first direction, the conveying line passes through the lower end of the square cylinder, the square cylinder has two first side walls perpendicular to the first direction and two second side walls parallel to the first direction, the top of the square cylinder is provided with an air supply pipe extending along the first direction, the air supply pipe can spray air flow toward the two second side walls in an inclined downward direction; the bottom end of the first side wall facing the direction of material coming from the conveying line is provided with a feed port, the bottom end of the other first side wall is provided with a first discharge port, and the top end of the square cylinder is provided with a second discharge port.

[0008] The inner wall surface of the second side wall is respectively provided with a linkage rod extending along the first direction, and the linkage rod can slide back and forth relative to the square tube along the first direction; a plurality of mounting seats are provided on the linkage rod, and a swing rod is installed on the mounting seat, one end of the swing rod is rotatably connected to the mounting seat, and the other end is a free end and the free end extends downwardly at an angle. The rotation axis of the swing rod is horizontal and parallel to the first direction, and the swing rod can swing back and forth in a vertical plane. The swing range of the swing rod is set to: the swing rod can swing downward until the free end contacts the conveyor line, and the swing rod can swing upward until it is horizontal.

[0009] Furthermore, a force-bearing support rod is fixed to one end of the swing rod that is rotatably connected to the mounting seat, the mounting seat is fixed to the linkage rod, a driving block is provided above each mounting seat, and the driving block is fixed to the second side wall; the driving block has two inclined surfaces that are connected at an angle and are arranged downward. The upper end of the force-bearing support rod abuts against the inclined surface, and an elastic reset member is installed between the swing rod and the mounting seat, and the elastic reset member drives the swing rod to rotate downward; when the linkage rod drives the swing rod to reciprocate and translate in the first direction, the force-bearing support rod slides along the inclined surface to make the upper end of the force-bearing support rod rise and fall, and make the swing rod swing back and forth.

[0010] The beneficial effects of one or more of the above technical solutions are:

[0011] In this solution, linkage rods are respectively arranged on the inner wall surfaces of the two second side walls, and the linkage rods can drive the mounting seat and the swing rod to move in a first direction; at the same time, the swing rod can stand and swing in a vertical plane; that is, the motion trajectory of the swing rod in this solution is the composite trajectory of the swing of the swing rod in the vertical plane and the translation of the swing rod in the first direction. This arrangement can firstly utilize the swing of the swing rod in the vertical plane to throw up the heavy garbage and light garbage on the upper surface of the conveyor line, thereby realizing the separation of the two in space, and avoiding the problem of poor separation effect of heavy garbage and light garbage during air selection. In addition, this arrangement can also utilize the translation of the swing rod in the first direction to enable the swing rod to avoid the rising light garbage, so that the light garbage can rise to the light outlet without being blocked by the swing rod.

[0012] In this solution, the driving block above the mounting seat is fixed to the second side wall; the driving block has two inclined surfaces connected at an angle and arranged downward; the upper end of the force-bearing support rod abuts against the inclined surface, and an elastic reset member is installed between the swing rod and the mounting seat, and the elastic reset member drives the swing rod to rotate downward; when the linkage rod drives the swing rod to reciprocate in the first direction, the force-bearing support rod slides along the inclined surface so that the force-bearing support rod rises and falls vertically. This arrangement enables the translation of the swing rod in the first direction to be converted into the up and down movement of the force-bearing support rod along the inclined surface at the driving block, and then the up and down movement of the force-bearing support rod is converted into the swing of the entire swing rod in the vertical plane. This arrangement makes the trajectory of the free end of the swing rod present an inverted V-shape, which can swing up and down to break up the garbage while avoiding the swing rod from hindering the rise of light garbage. In addition, this solution does not require an additional power source to drive the swing rod, and can achieve the synthesis of the translation and swinging trajectory of the swing rod, and the structural arrangement is convenient for controlling the trajectory of the translation of the swing rod in the first direction and the swing in the vertical direction.

DETAILED DESCRIPTION

[0025] The exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present invention, and are not intended to exhaust all possible modes of the present invention, nor to limit the scope of the present invention.

[0026] Reference Figure 1-Figure 11 One or more embodiments of the present invention provide a garbage air separation device, comprising a vertical square tube 5 and a conveying line 9 conveying along a horizontal first direction. In the present application, the conveying direction along the conveying line 9 is defined as the first direction, and the width direction of the conveying line 9 is defined as the second direction, and both the first direction and the second direction are set horizontally.

[0027] The conveyor line 9 passes through the lower end of the square tube 5. The square tube 5 has two first side walls 53 perpendicular to the first direction and two second side walls 52 parallel to the first direction. The top of the square tube 5 is provided with an air supply pipe 1 extending along the first direction. The air supply pipe 1 can spray air flow toward the two second side walls 52 in an inclined downward direction; the bottom end of the first side wall 53 facing the direction of the conveyor line 9 is provided with a feed port 81, the bottom end of the other first side wall 53 is provided with a first discharge port 8, and the top end of the square tube 5 is provided with a second discharge port 10.

[0028] See Figure 1The square cylinder 5 includes an upper cylinder 501 and a lower cylinder 502, and the inner cavities of the upper cylinder 501 and the lower cylinder 502 together enclose a separation chamber 51. The cross-sections of the upper cylinder 501 and the lower cylinder 502 are both square, and the lower end of the upper cylinder 501 and the upper end of the lower cylinder 502 are fixedly connected. As a specific structural form, the side walls of the upper cylinder 501 parallel to the first direction are inclined side walls, and the side walls of the lower cylinder 502 parallel to the first direction are vertical side walls. This arrangement makes it easy to use the inclined surface of the upper cylinder 501 to increase the space of the upper cylinder 501, thereby avoiding excessive space occupation caused by the air supply pipe 1 being set on the upper part of the square cylinder 5. In addition, see Figure 3 When the side wall of the upper cylinder 501 parallel to the first direction is an inclined side wall, relative to the vertical side wall, the angle between it and the inclined downward airflow output by the air supply pipe 1 is smaller, which facilitates the smooth downward transmission of the airflow output by the air supply pipe 1 along the inner wall of the upper cylinder 501, so as to reduce the probability of turbulence in the square cylinder 5.

[0029] When in use, the conveyor line 9 conveys the solid waste from its own feeding end to its own discharging end along the first direction. After the solid waste enters the interior of the square tube 5 along the conveyor line 9, the solid waste on the conveyor line 9 will obtain an upward lift under the action of the airflow. Specifically, the airflow discharged downwardly from the air delivery pipe 1 to both sides will first contact the second side wall 52 of the square tube 5, and then under the action of the Coanda effect, the airflow will flow downward close to the second side wall 52 until it contacts the conveyor line 9. At this time, because the air pressure intensity at the center of the separation chamber 51 in the square tube 5 is low, the airflow will move upward from the conveyor line 9 and carry the light waste to the second discharge port 10 for discharge. In order to further reduce the air pressure at the center of the separation chamber 51 in the square tube 5, in this embodiment, the first discharge port 8 is connected with an air outlet pipe 4, and the air outlet pipe 4 is connected with an air extraction device (not shown in the figure) so that an upward airflow is formed at the conveyor line 9. Specifically, the air outlet pipe 4 is connected to the second discharge port 10 at the upper end of the square tube 5 through the fixing sleeve 3. More specifically, the upper end of the square tube 5 is connected to the gas gathering hood 2 , and the upper end of the gas gathering hood 2 is provided with a second discharge port 10 .

[0030] Specifically, a row of air holes 101 is provided on both sides of the air supply pipe 1 along the second direction, and the air holes 101 in the same row are arranged in sequence along the first direction. One end of the air supply pipe 1 is a blocking end, which is inserted into the inner cavity of the square tube 5 and stops against the inner wall surface of the first side wall 53.

[0031] Specifically, the conveyor line 9 is installed on the support frame 6, and the lower end of the square tube 5 is fixed to the support frame 6 to achieve self-support. In addition, the support frame 6 has upward baffles on both sides along the second direction, and the lower end of the square tube 5 is arranged between the two baffles to improve the stability of the installation of the square tube 5.

[0032] It can be seen that, under the condition of controlling the airflow intensity output by the air delivery pipe 1 and the suction intensity of the air extraction device, the rising airflow intensity at the conveying line 9 can be set to: only be able to carry away light garbage upwards, but not heavy garbage. This setting method allows heavy garbage to be discharged from the first discharge port 8 along the conveying line 9, and light garbage to be discharged from the second discharge port 10 along with the upward airflow.

[0033] However, in actual use, heavy garbage and light garbage are mixed with each other, and it is easy for small pieces of heavy garbage to be mixed with light garbage and discharged from the second discharge port 10, while small pieces of light garbage are pressed by the heavy garbage on the conveying line 9 and discharged from the first discharge port 8 along the conveying line 9. Therefore, how to achieve the separation of heavy garbage and light garbage on the conveying line 9 affects the separation effect of the device using airflow to sort heavy and light garbage.

[0034] The inventor tried to set a swing rod that can swing up and down in the separation chamber 51, but the swing rod can only swing up and down, and the effect of breaking up the heavy garbage and the light garbage is not good. In addition, the vertical projection position of the swing rod does not change, and the light garbage under the swing rod is easily blocked by the swing rod and cannot rise smoothly. Therefore, in order to avoid the swing rod blocking the rise of light garbage when using the swing rod to break up light garbage and heavy garbage: in this embodiment, the inner wall surface of the second side wall 52 is respectively provided with a linkage rod 15 extending along the first direction, and the linkage rod 15 can slide back and forth relative to the square tube 5 along the first direction; a plurality of mounting seats 13 are provided on the linkage rod 15, and a swing rod 11 is installed on the mounting seat 13, one end of the swing rod 11 is rotatably connected to the mounting seat 13, and the other end is a free end and the free end extends downwardly at an angle; the rotation axis of the swing rod 11 is horizontal and parallel to the first direction, and the swing rod 11 can swing back and forth in a vertical plane; the swing range of the swing rod 11 is set as follows: the swing rod 11 can swing downward until the free end contacts the conveyor line 9, and the swing rod 11 can swing upward until it is in a horizontal state.

[0035] In the above technical solution, the swing rod 11 is rotatably connected to the mounting seat 13, and the mounting seat 13 is connected to the linkage rod 15, and the linkage rod 15 can slide along the first direction. At this time, the motion trajectory of the swing rod 11 is a combination of its translation along the first direction and its swinging trajectory along the vertical plane. This facilitates the use of the swing rod 11 to achieve vertical separation of light garbage and heavy garbage on the conveyor line 9, while using the swing rod 11 to achieve vertical separation, and to use the reciprocating translation of the swing rod 11 along the first direction to avoid the light garbage under the swing rod 11, so as to avoid the situation where some light garbage is always under the swing rod 11 and is blocked and cannot rise.

[0036] In order to increase the separation effect of the swing rod 11 on light garbage and heavy garbage, in this embodiment, a plurality of swing rods 11 are arranged at the second side wall 52 on both sides of the conveying line 9 along the second direction, and the plurality of swing rods 11 rotate in the vertical plane respectively. In this embodiment, a force-bearing support rod 111 is fixed to one end of the swing rod 11 that is rotatably connected to the mounting seat 13, and the mounting seat 13 is fixed to the linkage rod 15. A driving block 12 is arranged above each mounting seat 13, and the driving block 12 is fixed to the second side wall 52. The driving block 12 has two inclined surfaces 121 connected at an angle and arranged downward. The force-bearing support rod 111 abuts against the inclined surface 121, and an elastic reset member is installed between the swing rod 11 and the mounting seat 13, and the elastic reset member drives the swing rod 11 to rotate downward. When the linkage rod 15 drives the swing rod 11 to reciprocate and translate along the first direction, the force-bearing support rod 111 slides along the inclined surface 121 to make the upper end of the force-bearing support rod 111 rise and fall, and make the swing rod 11 swing back and forth.

[0037] In this embodiment, the mounting seats 13 on the two second side walls 52 are staggered along the first direction. This arrangement facilitates the distribution of the swing rods 11 at the two second side walls 52 along the first direction to be more uniform, avoids the swing rods 11 at the two side walls from interfering with each other during operation, and enables the two groups of swing rods 11 at the two second side walls 52 to cooperate with each other, thereby achieving a better effect of breaking up light garbage and heavy garbage.

[0038] In this embodiment, the two inclined surfaces 121 on the same driving block 12 are symmetrically arranged, and the connection between the two inclined surfaces 121 has an arc-shaped transition surface. Specifically, the extension direction of the inclined surface 121 here is parallel to the second direction, and the boundary line after the two inclined surfaces 121 are extended is perpendicular to the first direction and parallel to the second direction. The two inclined surfaces 121 are arranged symmetrically with respect to the vertical plane, and the arc-shaped transition surface here is used to reduce the friction between the force-bearing support rod 111 and the driving block 12, so that the top end of the force-bearing support rod 111 can smoothly transition between the two inclined surfaces 121.

[0039] In this embodiment, the square tube 5 has a second direction perpendicular to the second side wall 52, the square tube 5 has a symmetry plane passing through its own center point and perpendicular to the second direction, and the vertical projection of the swing rod 11 does not exceed the symmetry plane. Specifically, one end of the swing rod 11 is close to the second side wall 52, and the other end is arranged toward the center of the square tube 5 along the second direction and does not exceed the symmetry plane. This arrangement is convenient for reducing the probability of position interference between the two groups of swing rods 11 at the two second side walls 52.

[0040] The elastic reset member here can be a torsion spring (not shown in the figure), the swing rod 11 is rotatably connected to the mounting seat 13 through a rotating shaft, and the torsion spring is sleeved on the outside of the rotating shaft. Alternatively, the elastic reset member is a tension spring 17, and the two ends of the tension spring 17 are respectively connected to the square tube 5 and the swing rod 11.

[0041] See also Figure 5 and Fig. 9 , a plurality of rod sleeves 14 extending along the first direction are fixed on the second side wall 52, and the linkage rod 15 passes through the rod sleeves 14 to achieve its own support and guidance when sliding along the first direction. The rod sleeves 14 are fixed to the support plate 16, and the support plate 16 is fixed to the inner wall surface of the second side wall 52, and then the rod sleeves 14 are used to fix the inner wall of the square tube 5. A mounting seat 13 is fixed on the swing rod 11, and the swing rod 11 is rotatably connected to the mounting seat 13. At this time, one end of the tension spring 17 is fixed to the side of the swing rod 11 away from the force-bearing support rod 111, and the other end of the tension spring 17 is fixed to the support plate 16, so that the tension spring 17 is indirectly fixed to the second side wall 52.

[0042] Specifically, one end of the linkage rod 15 along the first direction is connected to a linear drive member, and the linear drive member is used to drive the linkage rod 15 to reciprocate and translate along the first direction. More specifically, the linear drive member here is an electric push rod 18, and the body of the electric push rod 18 is fixedly arranged outside the square tube 5. The telescopic rod of the electric push rod 18 passes through the mounting hole on the square tube 5 and is fixed to the end of the linkage rod 15. The linear drive member here can also be replaced by a hydraulic push rod or a linear motor.

[0043] See again Figure 5 and Fig. 9 In this embodiment, the rotating shaft between the mounting seat 13 and the rocker arm 11 is installed on the rocker arm 11. In order to avoid the problem that the force-bearing support rod 111 cannot move downward due to the dead point of movement: the projection of the force-bearing support rod 111 along its own length direction does not intersect with the rotating shaft, so that the direction of the driving force transmitted to the rocker arm 111 by the force-bearing support rod 111 does not pass through the rotating shaft.

[0044] In this embodiment, the swing arm 11 includes an elastic section and a rigid section that are spliced ​​and fixed along the length direction, and the rigid section is connected to the mounting seat 13. Specifically, one of the elastic section and the rigid section is provided with a slot (not shown in the figure), and the other is provided with a plug (not shown in the figure), and the plug can be fixedly plugged into the slot. The slot and the plug are provided with a snap-on structure that cooperates with each other. This arrangement facilitates the rapid connection of the elastic section and the rigid section, and facilitates the use of the deformable characteristics of the elastic part to avoid the problem of damage to the conveyor line 9 caused by the swing arm 11 directly contacting the conveyor line 9 or squeezing the waste on the surface of the conveyor line 9.

[0045] In this embodiment, a vertical curtain 7 is provided at the gap where the feed port 81 and the first discharge port 8 are located. The upper end of the curtain 7 is fixed to the square tube 5, and the lower end is suspended above the conveyor line 9. Specifically, the curtain 7 here is a square structure, and its material can be rubber or silicone. When the curtain 7 is used, the curtain 7 can be filled at the position of the feed port 81 and the first discharge port 8, which is convenient for increasing the air tightness of the square tube 5 while ensuring that the conveyor line 9 can carry solid waste in and out of the square tube 5.

[0046] In this embodiment, the conveyor line 9 is a belt conveyor line, and the part of the conveyor line 9 that passes through the square tube 5 is a separation section; along the second direction, the separation section is low in the middle and high on both sides. This arrangement makes it easy to utilize the characteristics of the conveyor line 9 being low in the middle and high on both sides, so that the light garbage and heavy garbage to be sorted converge in the middle of the square tube 5, so as to fully utilize the characteristics of the greater rising air flow intensity in the middle of the square tube 5, and improve the separation effect of light and heavy garbage.

[0047] In this embodiment, at the same second side wall 52, the angles between adjacent swing rods 11 and the horizontal plane are different. This arrangement makes it easy for adjacent swing rods 11 to alternately break up the heavy garbage and light garbage at the conveyor line 9. Specifically, one of the adjacent swing rods 11 contacts the conveyor line 9 through a free end, and the other free end rotates upward to the level of the swing rod 11. Considering that the conveyor line 9 is transported along the first direction, the swing rod 11 close to the incoming direction has just swung upward to the limit, and the subsequent other swing rod 11 takes over and swings upward from the bottom to further break up the heavy and light garbage, so as to achieve the work of multiple swing rods 11 alternating to break up the solid garbage in a certain area on the conveyor line 9.

[0048] Specifically, the swing rod 11 includes a first swing rod and a second swing rod alternately arranged along the first direction. At this time, except for the two outermost swing rods 11 along the first direction, the left and right sides of each first swing rod along the first direction are respectively the second swing rods, and the left and right sides of each second swing rod along the first direction are respectively the first swing rods. All the first swing rods have the same angle with the horizontal plane, and all the second swing rods have the same angle with the horizontal plane. This arrangement makes it easy to control the rhythm of the swing rod 11 for breaking up the solid waste on the conveyor line 9 moving horizontally along the first direction, and alternately break up the light waste and the heavy waste.

[0049] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make various combinations and modifications to the above-mentioned embodiments of the present invention under the guidance of the present invention without departing from the scope of the present invention.
