Solid waste sorting device

Abstract

This application relates to the field of solid waste treatment technology, and discloses a solid waste sorting device, including a horizontal plate, a vertical plate, a hollow shaft, an outer filter cylinder, a splined sleeve, a splined shaft, an inner filter cylinder, and a receiving box. In use, driven by an external force, the hollow shaft rotates, which in turn drives the outer filter cylinder to rotate. Simultaneously, it drives the splined sleeve to rotate, which in turn drives the splined shaft to rotate, ultimately driving the inner filter cylinder to rotate. This achieves synchronous rotation of the inner and outer filter cylinders, allowing for the screening of solid waste added to the inner filter cylinder, ensuring that appropriately sized solid waste falls through multiple inner and outer filter holes sequentially. Driven by an external force, the splined shaft slides, causing the inner filter cylinder to slide relative to the outer filter cylinder. This causes the multiple inner filter holes to misalign with the multiple outer filter cylinders, thereby changing the size of the diamond-shaped holes through which solid waste can pass. This allows for continuous adjustment of the sorting level, separating more types of solid waste with corresponding mesh sizes.

Description

Technical Field

[0001] This application relates to the field of solid waste treatment technology, and in particular to a solid waste sorting device. Background Technology

[0002] A related technology (publication number: CN219210575U) discloses a sorting device for solid waste treatment, including a supporting base plate and an inclined support rod disposed on the top surface of the supporting base plate. A mesh cylinder mounting frame is embedded in the top of the inclined support rod, and a main support rod is installed below the mesh cylinder mounting frame, with the inclined support rod and the main support rod being symmetrical to each other. A sorting mesh cylinder is rotatably installed inside the mesh cylinder mounting frame, and the outer surface of the sorting mesh cylinder is provided with small mesh holes for solid waste sorting and large hexagonal mesh holes for sorting.

[0003] In the process of implementing the technical solution disclosed herein, at least the following problems were found in the related technologies: This solid waste sorting device uses a small-mesh design to first sort small-diameter solid waste. Then, using a large-mesh hexagonal mesh, it can sort larger-diameter solid waste after the small-diameter waste has been sorted. However, the mesh size cannot be adjusted, therefore it can only sort two types of solid waste with corresponding mesh sizes, and cannot sort more types of solid waste with corresponding mesh sizes.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] To provide a basic understanding of some aspects of the disclosed technical solutions, a brief summary is given below. This summary is not a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these technical solutions, but rather serves as a prelude to the detailed explanations that follow.

[0006] This disclosure provides a solid waste sorting device that can sort out more types of solid waste with corresponding mesh sizes.

[0007] In some technical solutions, the solid waste sorting device includes: a horizontal plate for resting against the ground; a vertical plate connected to the top surface of the horizontal plate; a hollow shaft rotatably inserted through the vertical plate; an outer filter cartridge installed on the end face of the hollow shaft and coaxially distributed with the hollow shaft, the outer filter cartridge including a plurality of external diamond-shaped holes formed in its cylindrical sidewall; a spline sleeve installed inside the hollow shaft; a spline shaft slidably inserted through the spline sleeve and passing through the outer filter cartridge; and an inner filter cartridge installed at the end of the spline shaft. The inner filter cylinder has a cylindrical sidewall that fits against the cylindrical sidewall of the outer filter cylinder. The outer filter cylinder includes multiple inner diamond-shaped holes formed on its cylindrical sidewall, with each inner diamond-shaped hole facing an outer diamond-shaped hole. A receiving box is mounted on the vertical plate and surrounds the outer filter cylinder. The hollow shaft is controllably rotatable to allow the outer and inner filter cylinders to rotate synchronously, and the spline shaft is controllably slidable to allow the outer diamond-shaped holes of the outer filter cylinders and the inner diamond-shaped holes of the inner filter cylinders to be misaligned.

[0008] Optionally, it further includes: a motor mounted on the top surface of the horizontal plate; a driving pulley mounted on the rotating end of the motor; a driven pulley mounted on the outer wall of the hollow shaft; and a belt fitted between the driving pulley and the driven pulley.

[0009] Optionally, it further includes: an electric actuator mounted on the vertical plate; and a movable plate mounted on the movable end of the electric actuator and rotatably fitted onto the spline shaft.

[0010] Optionally, it further includes: a first bearing, mounted between the movable plate and the spline shaft.

[0011] Optionally, it further includes: a feeding cylinder, rotatably mounted on the cylindrical sidewall of the outer filter cylinder, one end of the feeding cylinder being located inside the inner filter cylinder, and the other end of the feeding cylinder passing through the receiving box; a feeding hopper, mounted at the end of the feeding cylinder and located outside the receiving box; and a support leg, mounted between the outer wall of the feeding hopper and the top surface of the horizontal plate.

[0012] Optionally, it also includes a second bearing, installed between the feed cylinder and the outer filter cylinder.

[0013] Optionally, it further includes: a bearing housing, installed on the side wall of the vertical plate and the receiving box, and sleeved on the hollow shaft; and a third bearing, installed between the hollow shaft and the bearing housing.

[0014] Optionally, it further includes: a discharge hopper, connected to the bottom surface of the receiving box and communicating with the interior of the receiving box.

[0015] Optionally, it also includes a reinforcing member installed at the connection between the horizontal plate and the vertical plate.

[0016] The solid waste sorting device provided in this disclosure can achieve the following technical effects: This disclosure provides a solid waste sorting device, comprising a horizontal plate, a vertical plate, a hollow shaft, an outer filter cartridge, a splined sleeve, a splined shaft, an inner filter cartridge, and a receiving box. The horizontal plate rests against the ground, supporting the entire device. The vertical plate is connected to the top surface of the horizontal plate, and its plane is perpendicular to the plane of the horizontal plate. The hollow shaft rotatably passes through the vertical plate, its axis perpendicular to the plane of the vertical plate. The outer filter cartridge is installed on the end face of the hollow shaft and is coaxially distributed with it. The outer filter cartridge includes multiple external diamond-shaped holes formed in its cylindrical sidewall for the passage of solid waste. The splined sleeve is installed inside the hollow shaft to support and install the slidable splined shaft. The splined shaft slidably passes through the splined sleeve and through the outer filter cartridge, sliding relative to the splined sleeve and rotating under the drive of the splined sleeve. The inner filter cartridge is mounted on the end face of the splined shaft and located inside the outer filter cartridge. The cylindrical sidewall of the inner filter cartridge fits against the cylindrical sidewall of the outer filter cartridge to prevent solid waste from entering between the inner and outer filter cartridges. The outer filter cartridge includes multiple inner diamond-shaped holes formed on its cylindrical sidewall, which are respectively opposite to multiple outer diamond-shaped holes and are also used to pass solid waste. The receiving box is mounted on a vertical plate and surrounds the outer filter cartridge, used to receive solid waste separated from the multiple inner and outer filter holes. The hollow shaft can be rotated in a controlled manner to make the outer and inner filter cartridges rotate synchronously, and the splined shaft can be slid in a controlled manner to make the multiple outer and inner filter holes misaligned.

[0017] In operation, driven by external force, the hollow shaft rotates, which in turn drives the outer filter cartridge to rotate. Simultaneously, this drives the spline sleeve to rotate, which in turn drives the spline shaft, ultimately causing the inner filter cartridge to rotate. This achieves synchronous rotation of the inner and outer filter cartridges, allowing for the screening of solid waste added to the inner filter cartridge. Solid waste of suitable size passes through multiple inner and outer filter holes sequentially. Driven by external force, the spline shaft slides, causing the inner filter cartridge to slide relative to the outer filter cartridge. This misaligns the multiple inner filter holes with the multiple outer filter cartridges, changing the size of the diamond-shaped holes through which solid waste can pass. This allows for continuous adjustment of the sorting level, separating more types of solid waste with corresponding mesh sizes.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0029] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides a solid waste sorting device, including a horizontal plate 1, a vertical plate 2, a hollow shaft 3, an outer filter cylinder 4, a spline sleeve 5, a spline shaft 6, an inner filter cylinder 7, and a receiving box 8. The horizontal plate 1 is used to abut against the ground, thereby supporting the entire device. The vertical plate 2 is connected to the top surface of the horizontal plate 1, and the plane of the vertical plate 2 is perpendicular to the plane of the horizontal plate 1. The hollow shaft 3 is rotatably inserted through the vertical plate 2, and the axis of the hollow shaft 3 is perpendicular to the plane of the vertical plate 2. The outer filter cylinder 4 is installed on the end face of the hollow shaft 3 and is coaxially distributed with the hollow shaft 3. The outer filter cylinder 4 includes multiple outer diamond-shaped holes formed in its cylindrical sidewall, which are used for the passage of solid waste. The spline sleeve 5 is installed inside the hollow shaft 3 to support and install the slidable spline shaft 6. The spline shaft 6 is slidably inserted through the spline sleeve 5 and passes through the outer filter cylinder 4, and can slide relative to the spline sleeve 5, rotating under the drive of the spline sleeve 5. The inner filter cartridge 7 is mounted on the end face of the splined shaft 6 and located inside the outer filter cartridge 4. The cylindrical sidewall of the inner filter cartridge 7 fits against the cylindrical sidewall of the outer filter cartridge 4 to prevent solid waste from entering between the outer filter cartridge 4 and the inner filter cartridge 7. The outer filter cartridge 4 includes multiple inner diamond-shaped holes formed on its cylindrical sidewall, which are respectively opposite to multiple outer diamond-shaped holes and are also used to pass solid waste. The receiving box 8 is mounted on the vertical plate 2 and surrounds the outer filter cartridge 4, and is used to receive solid waste separated from the multiple inner filter holes and multiple outer filter holes. The hollow shaft 3 can be rotated in a controlled manner to make the outer filter cartridge 4 and the inner filter cartridge 7 rotate synchronously, and the splined shaft 6 can be slid in a controlled manner to make the multiple outer filter holes and multiple inner filter holes misaligned.

[0030] This embodiment of the solid waste sorting device, driven by an external force, rotates the hollow shaft 3, which in turn drives the outer filter cylinder 4 to rotate. Simultaneously, it drives the spline sleeve 5 to rotate, which in turn drives the spline shaft 6 to rotate, ultimately driving the inner filter cylinder 7 to rotate. This achieves synchronous rotation of the inner filter cylinder 7 and the outer filter cylinder 4, allowing for the screening of solid waste added to the inner filter cylinder 7, ensuring that appropriately sized solid waste falls out sequentially through multiple inner and outer filter holes. Driven by an external force, the spline shaft 6 slides, causing the inner filter cylinder 7 to slide relative to the outer filter cylinder 4. This causes the multiple inner filter holes to be misaligned with the multiple outer filter cylinders 4, thereby changing the size of the diamond-shaped holes through which solid waste can pass. This allows for continuous adjustment of the sorting level, enabling the sorting of more types of solid waste with corresponding mesh sizes.

[0031] Optionally, combined Figure 1 and Figure 5 As shown, it also includes a motor 9, a drive pulley, a driven pulley, and a belt 10. The motor 9 is mounted on the top surface of the horizontal plate 1 to provide driving force for rotational motion. The drive pulley is mounted on the rotating end of the motor 9 and rotates under the drive of the motor 9. The driven pulley is mounted on the outer wall of the hollow shaft 3 to drive the hollow shaft 3 to rotate. The belt 10 is fitted between the drive pulley and the driven pulley to transmit driving force.

[0032] In this embodiment, controlling the motor 9 to operate drives the drive pulley to rotate. The belt 10 then drives the driven pulley to rotate, which in turn drives the hollow shaft 3 to rotate, ultimately achieving synchronous rotation of the outer filter cartridge 4 and the inner filter cartridge 7.

[0033] Optionally, combined Figure 1 and Figure 5 As shown, it also includes an electric actuator 11 and a movable plate 12. The electric actuator 11 is mounted on the vertical plate 2 to provide driving force for linear movement. The movable plate 12 is mounted on the moving end of the electric actuator 11 and moves under the drive of the electric actuator 11. The movable plate 12 is rotatably mounted on the splined shaft 6, and the two can rotate relative to each other to prevent the movable plate 12 from rotating under the drive of the splined shaft 6.

[0034] In this embodiment, controlling the electric push rod 11 to work can drive the moving plate 12 to move, which in turn drives the spline shaft 6 to move, ultimately realizing the function of the inner filter cartridge 7 sliding relative to the outer filter cartridge 4.

[0035] Optionally, combined Figure 1 and Figure 3 As shown, it also includes a first bearing 13. The first bearing 13 is installed between the movable plate 12 and the splined shaft 6.

[0036] In this embodiment, a first bearing 13 is also included, which is installed between the movable plate 12 and the splined shaft 6. The first bearing 13 is used to reduce the friction between the movable plate 12 and the splined shaft 6, thereby reducing wear and damage.

[0037] Optionally, combined Figure 1 and Figure 5 As shown, the system also includes a feeding cylinder 14, a feeding hopper 15, and a support leg 16. The feeding cylinder 14 is rotatably mounted on the cylindrical side wall of the outer filter cylinder 4. One end of the feeding cylinder 14 is located inside the inner filter cylinder 7, and the other end passes through the receiving box 8, allowing it to rotate relative to the outer filter cylinder 4. The feeding hopper 15 is installed at the end of the feeding cylinder 14 and located outside the receiving box 8, for feeding materials. The support leg 16 is installed between the outer wall of the feeding hopper 15 and the top surface of the horizontal plate 1, for determining the relative position of the feeding hopper 15 and the horizontal plate 1.

[0038] In this embodiment, since the feeding cylinder 14 and the outer filter cylinder 4 are rotatable relative to each other, the feeding cylinder 14 will not rotate with the rotation of the outer filter cylinder 4, thereby fixing the position of the feeding hopper 15 and facilitating feeding. Furthermore, supported by the support leg 16, the feeding hopper 15, and the feeding cylinder 14, the other side of the outer filter cylinder 4 and the receiving box 8 can be supported. This forms stable support on both sides of the outer filter cylinder 4 and the receiving box 8, improving the stability of the device.

[0039] Optionally, combined Figure 1 and Figure 4 As shown, it also includes a second bearing 17. The second bearing 17 is installed between the feed cylinder 14 and the outer filter cylinder 4.

[0040] In this embodiment, a second bearing 17 is also included, which is installed between the feed cylinder 14 and the outer filter cylinder 4. The second bearing 17 is used to allow the feed cylinder 14 and the outer filter cylinder 4 to rotate relative to each other and to reduce the friction between the feed cylinder 14 and the outer filter cylinder 4.

[0041] Optionally, combined Figure 1 and Figure 2 As shown, it also includes a bearing housing 18 and a third bearing 19. The bearing housing 18 is installed on the side wall of the vertical plate 2 and the receiving box 8, and is sleeved on the hollow shaft 3. The third bearing 19 is installed between the hollow shaft 3 and the bearing housing 18.

[0042] In this embodiment, the bearing housing 18 is installed on the side wall of the vertical plate 2 and the receiving box 8 to support the installation of the third bearing 19. The third bearing 19 is used to support the installation of the rotatable hollow shaft 3, reduce the frictional force on the hollow shaft 3, and improve the rotational accuracy of the hollow shaft 3.

[0043] Optionally, combined Figure 1 and Figure 5 As shown, it also includes a discharge hopper 20. The discharge hopper 20 is connected to the bottom surface of the receiving box 8 and communicates with the interior of the receiving box 8.

[0044] In this embodiment, a discharge hopper 20 is also included, which is connected to the bottom surface of the receiving box 8 and communicates with the interior of the receiving box 8. The discharge port is used to discharge the sorted solid waste to facilitate the collection of solid waste.

[0045] Optionally, combined Figure 1 and Figure 5 As shown, it also includes a reinforcing member 21. The reinforcing member 21 is installed at the connection between the horizontal plate 1 and the vertical plate 2.

[0046] In this embodiment, a reinforcing member 21 is also included at the connection between the horizontal plate 1 and the vertical plate 2. The reinforcing member is used to improve the connection strength between the horizontal plate 1 and the vertical plate 2, so as to prevent the connection between the horizontal plate 1 and the vertical plate 2 from falling off or deforming under the action of external force.
