DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] Example: Figure 1 - Figure 7As shown, an industrial solid waste pretreatment system includes a chopping device 1, a first horizontal conveyor belt 3 is installed on the right side of the chopping device 1, a lifting conveyor belt 4 is installed on the right side of the first horizontal conveyor belt 3, a cylindrical magnet 17 is installed on the right side of the top of the lifting conveyor belt 4, a second horizontal conveyor belt 5 is installed below the right side of the cylindrical magnet 17, a bulking mechanism 2 is installed on the left side of the first horizontal conveyor belt 3, a mounting conveyor belt 6 is installed above the first horizontal conveyor belt 3, hook components 7 are evenly installed on the mounting conveyor belt 6, a turning mechanism 8 is installed on the left side of the mounting conveyor belt 6, and a first output conveyor belt 9 is installed below the left side of the turning mechanism 8, the outer surface of the first output conveyor belt 9 is rough, and the cylindrical magnet 17 is installed on the right side of the top of the lifting conveyor belt 4. A second output conveyor belt 10 is arranged on the lower left side of the magnet 17, a third output conveyor belt 11 is installed on the lower right side of the second horizontal conveyor belt 5, a scraper plate 22 is installed on the lower left side of the cylindrical magnet 17, a first guide plate 12 is fixedly connected to the left side of the fixed frame 21, and the first guide plate 12 extends to the top of the second output conveyor belt 10, a second guide plate 13 is fixedly connected to the right side of the top of the fixed frame 21, and the second guide plate 13 extends to the top of the third output conveyor belt 11, the installation conveyor belt 6 is divided into two parts, horizontal and inclined upward, and the movement direction of the installation conveyor belt 6 is opposite to the movement direction of the first horizontal conveyor belt 3, and the whole system is controlled by a PLC control system;

[0031] The waste enters the chopping device 1, under the action of the chopping device 1, the waste is divided into single waste bags, and the single waste bags come out of the chopping device 1 and fall onto the first horizontal conveyor belt 3. As the first horizontal conveyor belt 3 moves to the right, the single waste bags enter the dispersing mechanism 2 and are dispersed by the dispersing mechanism 2. The dispersed single waste bags continue to move to the right. When they move to the right side of the first horizontal conveyor belt 3, the hook assembly 7 installed on the conveyor belt 6 acts on the single waste bag. The hook assembly 7 hooks up the cloth strips and lifts the cloth strips and other strip-shaped debris in the single waste bag from right to left. When it reaches the highest point, the flipping mechanism 8 works to pick up the cloth strips and put them on the first output conveyor belt 9. The remaining waste is left. Plastic and metal wastes are transported from the first horizontal conveyor belt 3 to the lifting conveyor belt 4, and then pass through the cylindrical magnet 17. The cylindrical magnet 17 absorbs the magnetic metal, and the non-magnetic metal and plastic fall from the cylindrical magnet 17 to the second horizontal conveyor belt 5. The larger magnetic metal falls to the second output conveyor belt 10 under the action of gravity, and the smaller magnetic metal is scraped off the cylindrical magnet 17 by the scraper plate 22 and falls to the second output conveyor belt 10. The non-magnetic metal and plastic fall to the third output conveyor belt 11. The second output conveyor belt 10 and the third output conveyor belt 11 pass through the water pool, and the plastic and some rags float on the water surface. The metal and plastic are separated, and the sorting effect is better.

[0032] Specifically, refer to Figure 4The dispersing mechanism 2 includes a shell 201, which is arranged at the discharging position of the chopping device 1. The middle part of the shell 201 is rotatably connected to a first mounting shaft 202, and a plurality of levers 203 are evenly mounted on the first mounting shaft 202. A motor is mounted at one end of the first mounting shaft 202. After a single bag of waste enters the shell 201, the motor drives the first mounting shaft 202 to rotate rapidly, and the rapidly moving lever 203 acts on the single bag of waste, so that the rapidly moving lever 203 breaks up the single bag of waste.

[0033] Specifically, refer to Figure 5 The hook assembly 7 includes a fixed block 701, and the fixed block 701 is fixedly connected to the outer side of the installation conveyor belt 6. A mounting plate 702 is provided on the outer side of the fixed block 701. A hook 703 is fixedly connected to the outer side of the mounting plate 702. The hooks 703 between two adjacent hook assemblies 7 are staggered with each other, so that the front and rear hooks 703 act at different positions and can hook up the cloth strip as much as possible. A sharp protrusion is provided at the working position of the hook 703, so that the hook 703 can better hook with the cloth strip. The hook 703 moves with the installation conveyor belt 6 to lift the cloth strip so that the cloth strip is in a vertical state during the movement, so that the solid debris in the cloth strip can fall from the cloth strip to the first horizontal conveyor belt 3 under the action of gravity for preliminary sorting.

[0034] For further reference, Figure 1 , Figure 2 and Figure 5, the front and rear sides of the mounting plate 702 are fixedly connected with connecting columns 704, the front and rear sides of the fixing block 701 are fixedly connected with ear plates 705, and the connecting columns 704 pass through the ear plates 705, and the outer side of the connecting columns 704 is sleeved with springs 706, and the two ends of the springs 706 are fixedly connected to the connecting columns 704 and the ear plates 705 respectively, and the front and rear sides of the installation conveyor belt 6 are provided with corrugated rods 15, and the corrugated rods 15 are parallel to the installation conveyor belt 6, and the bottom end of the corrugated rods 15 is provided with transition fillets, so that the round rods 707 can stably enter the upper concave position in the corrugated rods 15, and the sides of the corrugated rods 15 are fixedly connected with a plurality of support rods 16, and the front and rear sides of the mounting plate 702 are fixedly connected with round rods 707, and the round rods 707 cooperate with the corrugated rods 15, the hook assembly 7 moves with the installation conveyor belt 6, and the hooks 703 hook the cloth strip , and lift it. When the hook assembly 7 moves to the corrugated rod 15, the round rod 707 enters the corrugated rod 15. When the round rod 707 moves from the upper concave position of the corrugated rod 15 to the lower convex position, the mounting plate 702 is driven by the round rod 707 to separate from the fixed block 701, and the connecting column 704 moves in the ear plate 705, thereby compressing the spring 706. When the round rod 707 moves from the lower convex position of the corrugated rod 15 to the lower concave position, the effect of the corrugated rod 15 on the round rod 707 is reduced. At this time, the spring 706 resets, pushing the connecting column 704 to reset, so that the mounting plate 702 and the fixed block 701 are reunited. In the process of the round rod 707 moving along the corrugated rod 15, the hook 703 shakes perpendicular to the movement path. In the process of shaking, those solid debris with smaller mass can be shaken off from the cloth strip, making the sorting more complete.

[0035] Preferably, Figure 5 A plurality of insertion holes 708 are provided on the outer side of the fixed block 701, and a plurality of insertion rods 709 are fixedly connected to the side of the mounting plate 702 facing the fixed block 701, and the insertion rods 709 are arranged in the insertion holes 708. During the opening and closing process of the mounting plate 702 and the fixed block 701, the insertion rods 709 move inside the insertion holes 708, guiding the mounting plate 702, so that the movement of the mounting plate 702 remains stable.

[0036] Specifically, refer to Figure 1 and Figure 6The flip mechanism 8 includes a second mounting shaft 801, and the second mounting shaft 801 is rotatably connected to the top of the first output conveyor belt 9. Three groups of connecting arms 802 are fixedly connected to the outer side of the second mounting shaft 801. The ends of the three groups of connecting arms 802 are all provided with connecting rods 804. A cross bar 805 is fixedly connected between the two connecting rods 804 of the same group. A motor is installed at the end of the second mounting shaft 801. The hook component 7 brings the cloth strip to the top of the mounting conveyor belt 6. At this time, the motor drives the second mounting shaft 801 to rotate, so that the connecting arm 802 and the connecting rod 804 rotate, and then the cross bar 805 rotates. The moving cross bar 805 acts on the cloth strip hooked by the hook component 7 from bottom to top, removes the cloth strip from the hook component 7, and then sends it to the first output conveyor belt 9. Under the action of large friction on the first output conveyor belt 9, the cloth strip is removed from the cross bar 805 and goes to the next process.

[0037] Specifically, refer to Figure 1 The end of the connecting arm 802 is fixedly connected with a connecting shaft 803, and the connecting shaft 803 is rotatably connected to the end of the connecting rod 804. A torsion spring 806 is sleeved on the outer side of the connecting shaft 803. The two ends of the torsion spring 806 are respectively fixedly connected to the connecting rod 804 and the connecting shaft 803. The connecting rod 804 partially overlaps with the hook 703, and the connecting rod 804 partially overlaps with the hook 703. The speed of the cross bar 805 is greater than the speed of the hook assembly 7, which makes the cross bar 805 collide with the hook 703 during the movement. When the cross bar 805 hits the hook 703 , the connecting rod 804 rotates around the connecting shaft 803 and twists the torsion spring 806 until the cross bar 805 slides over the end of the hook 703, so that the cross bar 805 can contact the cloth strip as much as possible, so that the cloth strip is transferred from the hook 703 to the cross bar 805, and the cross bar 805 slides over the hook 703 from bottom to top. When the cross bar 805 passes over the hook 703, the connecting rod 804 is reset under the action of the torsion spring 806, and the cross bar 805 moves in the direction of installing the conveyor belt 6, thereby driving the cloth strip to move to the inside of the hook 703, making it easier for the cloth strip to detach from the hook 703.

[0038] Specifically, refer to Figure 1 , Figure 3 and Figure 7A fixing frame 21 is installed on both the front and rear sides of the cylindrical magnet 17. A driving gear 18 is fixedly connected to the front end of the cylindrical magnet 17. The outer side of the driving gear 18 is meshedly connected to two transmission gears 19. The outer sides of the two transmission gears 19 are meshedly connected to driven gears 20. The two driven gears 20 are respectively fixedly connected to the rollers of the lifting conveyor belt 4 and the second horizontal conveyor belt 5. A motor is installed on the front side of the driving gear 18. The size of the driving gear 18 is larger than that of the driven gear 20. The motor drives the driving gear 18 to rotate. Under the action of the two transmission gears 19, the belt The two driven gears 20 are driven to rotate, thereby making the lifting conveyor belt 4, the cylindrical magnet 17 and the second horizontal conveyor belt 5 work simultaneously. The top end of the lifting conveyor belt 4 is arranged on the upper left side of the cylindrical magnet 17, and the second horizontal conveyor belt 5 is arranged on the lower right side of the cylindrical magnet 17. The cylindrical magnet 17 partially overlaps with the lifting conveyor belt 4 and the second horizontal conveyor belt 5 in the vertical direction. Debris falls from the lifting conveyor belt 4 onto the cylindrical magnet 17, the magnetic metal is absorbed by the cylindrical magnet 17, and the non-magnetic metal and other solid debris are pushed by the cylindrical magnet 17 and fall onto the second horizontal conveyor belt 5.

[0039] Specifically, refer to Figure 1 A transverse plate 14 is provided above the middle of the first horizontal conveyor belt 3, and a blade is installed on the right side of the transverse plate 14. When the waste comes out of the dispersing mechanism 2, part of the cloth strip is wrapped around the surface of the hard debris. When the hook 703 hooks the cloth strip, the hard debris wrapped around the cloth strip will be lifted up. At this time, the end of the cloth strip moves with the hook 703, and the cloth strip passes through the transverse plate 14 during the movement. As the cloth strip moves, the hard debris is stuck by the transverse plate 14 until the blade on the transverse plate 14 cuts the cloth strip, and the hard debris falls onto the first horizontal conveyor belt 3. When the cloth strip passes through the transverse plate 14, the upper surface of the cloth strip moves relative to the transverse plate 14, and the transverse plate 14 can clean up the metal debris with smaller mass on the surface of the cloth strip.

[0040] Working principle: The waste enters the chopping device 1, under the action of the chopping device 1, the waste is divided into single waste packages, and after the single waste packages come out of the chopping device 1, they fall onto the first horizontal conveyor belt 3 and move to the right along with the first horizontal conveyor belt 3;

[0041] When a single bag of waste enters the dispersing mechanism 2, the motor drives the first mounting shaft 202 to rotate rapidly, and the rapidly moving lever 203 acts on the single bag of waste. The rapidly moving lever 203 breaks up the single bag of waste and discharges it from the outlet on the right side of the housing 201.

[0042] When it moves to the right side of the first horizontal conveyor belt 3, the hook 703 on the installation conveyor belt 6 acts on the waste bag to hook up the cloth strip, so that the cloth strip is in a vertical state during the movement, so that the solid debris in the cloth strip can fall from the cloth strip to the first horizontal conveyor belt 3 under the action of gravity. The hook 703 moves with the installation conveyor belt 6, and the cloth strip passes through the transverse plate 14 during the movement. As the cloth strip moves, the hard debris is stuck by the transverse plate 14 until the blade on the transverse plate 14 cuts the cloth strip, and the hard debris falls onto the first horizontal conveyor belt 3;

[0043] The hook assembly 7 continues to move upward with the installation conveyor belt 6, and the round rod 707 enters the corrugated rod 15. When the round rod 707 moves from the upper concave position of the corrugated rod 15 to the lower convex position, the installation plate 702 is driven by the round rod 707 to separate from the fixed block 701, and the connecting column 704 moves in the ear plate 705, thereby compressing the spring 706. When the round rod 707 moves from the lower convex position of the corrugated rod 15 to the lower concave position, the round rod 707 is less affected by the corrugated rod 15. At this time, the spring 706 is reset, pushing the connecting column 704 to reset, so that the installation plate 702 and the fixed block 701 are reunited. In the process of the round rod 707 moving along the corrugated rod 15, the hook 703 shakes perpendicular to the movement path, and those solid debris with smaller mass can be shaken off from the cloth strip during the shaking process;

[0044] When the hook assembly 7 brings the cloth strip to the top of the installation conveyor belt 6, the motor drives the second installation shaft 801 to rotate, so that the connecting arm 802 and the connecting rod 804 rotate. When the cross bar 805 hits the hook 703, the connecting rod 804 rotates around the connecting shaft 803 and twists the torsion spring 806 until the cross bar 805 slides over the end of the hook 703 and overlaps with the cloth strip. When the cross bar 805 passes over the hook 703, the connecting rod 804 is reset under the action of the torsion spring 806, and the cross bar 805 moves toward the installation conveyor belt 6, thereby driving the cloth strip to move to the inner side of the hook 703, removing the cloth strip from the hook assembly 7, and then sending it to the first output conveyor belt 9, and entering the next process with the first output conveyor belt 9;

[0045] The remaining waste materials include plastics and metals. The waste materials are transferred from the first horizontal conveyor belt 3 to the lifting conveyor belt 4, and then pass through the cylindrical magnet 17. The cylindrical magnet 17 absorbs the magnetic metals, and the non-magnetic metals and plastics fall from the cylindrical magnet 17 to the second horizontal conveyor belt 5. The larger magnetic metals fall to the second output conveyor belt 10 under the action of gravity, and the smaller magnetic metals are scraped off the cylindrical magnet 17 by the scraper plate 22 and fall to the second output conveyor belt 10. The non-magnetic metals and plastics fall to the third output conveyor belt 11. The second output conveyor belt 10 and the third output conveyor belt 11 pass through the water pool, and the plastics and some rags float on the water surface, and the metals and plastics are separated.
