Description

Technical Field

[0001] This invention belongs to the field of solid waste recycling and processing technology, and specifically relates to a solid waste treatment device. Background Technology

[0002] Ring die briquetting machines are commonly used solid waste treatment equipment. Solid waste such as cloth and leather is crushed and then fed into the ring die briquetting machine, which compresses the waste materials into blocks. These blocks can be used as biomass fuel. A ring die briquetting machine generally includes a ring die and pressure rollers that roll along the inner wall of the die. The side wall of the ring die has die holes. Under the pressure of the rollers, the material gradually exits from the die holes to the outside of the ring die. Existing ring die briquetting machines generally have a receiving tray on the outside of the die. During operation, the receiving tray is constantly rotating. However, the material discharge process is generally not continuous. After being extruded from the die holes, the material needs to reach a certain length before it naturally breaks and falls onto the receiving tray. Furthermore, after the material falls, the formation of the next piece takes time. This results in the receiving tray being idle most of the time, or conveying very little material per unit time, leading to unnecessary energy waste and increased electricity costs. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a solid waste treatment device that can effectively reduce energy consumption.

[0004] To achieve the above and other related objectives, the present invention provides a solid waste treatment apparatus, comprising:

[0005] Base plate;

[0006] A ring die is installed on the upper part of the base plate and forms a compression cavity with the base plate. Multiple discharge ports are evenly provided on the side wall of the ring die along the circumferential direction.

[0007] A roller pressing assembly is installed in the compression chamber. The roller pressing assembly includes a rotary support that is rotatably arranged along a vertical axis and a pressure roller that is rotatably connected to the rotary support. At least two pressure rollers are provided along the circumference of the ring die. The pressure rollers form a rolling fit with the inner wall of the ring die. The rotary support is connected to the main shaft, and the main shaft is connected to the drive motor.

[0008] A cutting mechanism is installed on the outside of the ring die, and the cutting mechanism includes an annular cutter that reciprocates along the axial direction of the ring die;

[0009] The receiving tray is rotatably disposed outside the ring mold and below the discharge port. The receiving tray is connected to the main shaft for transmission, and a clutch mechanism is provided between the receiving tray and the main shaft so that the receiving tray can rotate intermittently.

[0010] In an optional embodiment of the present invention, a driving gear is provided on the main shaft, and a driven gear is provided on the bracket below the base plate. The driven gear is coaxially fixedly connected to the first pulley. The bracket is also provided with a slide seat that is radially movable along the main shaft. A second pulley is provided on the slide seat. The second pulley is coaxially fixedly connected to the drive roller. The second pulley and the first pulley are connected by a belt to form a transmission engagement. When the slide seat slides, the drive roller can be made to fit or separate from the inner wall of the receiving tray.

[0011] In an optional embodiment of the present invention, the bracket is further provided with a tensioning wheel, the tensioning wheel is mounted on a movable frame, the movable frame is movably connected to the bracket, and a first elastic element is provided between the movable frame and the bracket, and the belt is arranged to pass around the tensioning wheel.

[0012] In an optional embodiment of the present invention, the clutch mechanism includes a lifting support, a connecting rod is hinged between the lifting support and the slide, and the lifting support is connected to a vertically arranged linear drive element.

[0013] In an optional embodiment of the present invention, a linkage mechanism is provided between the clutch mechanism and the cutting mechanism. The linkage mechanism is configured such that when the clutch mechanism drives the drive roller to fit against the inner wall of the receiving tray, the clutch mechanism can simultaneously drive the annular cutter to rise a certain distance and then automatically fall to cut off the material outside the discharge port.

[0014] In an optional embodiment of the present invention, the lower end of the annular cutter is connected to a transmission plate, and the linkage mechanism includes a column fixedly connected to the lifting support. The upper end of the column is provided with a movable stop block, which is slidably arranged along the radial direction of the column. The upper end of the column is also provided with a driving block, which is slidably arranged along the axial direction of the column. The driving block is provided with a driving pin, and the movable stop block is provided with an inclined groove that slidably engages with the driving pin. A second elastic element is provided between the driving block and the column. When the lifting support is at a low position within its stroke, the driving block is pushed upward under the action of the second elastic element. At this time, the movable stop block can protrude to the underside of the transmission plate so that the annular cutter can be driven upward synchronously during the lifting process of the lifting support. When the lifting support is at a high position within its stroke, the driving block abuts against the bottom surface of the base plate so that the driving block retracts downward relative to the column. At this time, the driving block can drive the movable stop block to be pulled away from the bottom of the transmission plate so that the annular cutter can be reset downward.

[0015] In an optional embodiment of the present invention, a third elastic element is further provided between the transmission plate and the base plate.

[0016] In an optional embodiment of the present invention, a surrounding wall is further included, the surrounding wall being disposed around the receiving tray, the surrounding wall being provided with a discharge port, and an inclined plate being provided at the discharge port, the inclined plate being fixedly connected to one side of the discharge port, the inclined plate extending above the receiving tray, for guiding the material on the receiving tray to the discharge port.

[0018] In an optional embodiment of the present invention, the main shaft and the drive motor are connected by a pulley mechanism, and the linear drive element is an electric cylinder.

[0019] The technical advantages of this invention are as follows: The cutting structure of this invention can actively cut the material to ensure that the material length is consistent. At the same time, the cutting structure can cooperate with the receiving tray. Before the receiving tray starts to rotate each time, the cutting mechanism performs a cutting action to ensure that the material falls completely. Then the receiving tray discharges these materials in a concentrated manner, avoiding the receiving tray from being empty, improving the conveying efficiency of the receiving tray during operation, and reducing the overall energy consumption of the equipment.

[0027] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0029] Figure 1-7 The invention provides a solid waste treatment device, specifically a ring die briquetting machine, which includes a base plate 10, a ring die 11, and a roller pressing assembly. The ring die 11 is installed on the upper end of the base plate 10 and forms a compression cavity with the base plate 10. A plurality of discharge ports 111 are evenly provided on the side wall of the ring die 11 along the circumference. The roller pressing assembly is installed in the compression cavity. The roller pressing assembly includes a rotary support 12 rotatably arranged along a vertical axis and pressure rollers 13 rotatably connected to the rotary support 12. At least two pressure rollers 13 are provided along the circumference of the ring die 11. The pressure rollers 13 form a rolling fit with the inner wall of the ring die 11. The rotary support 12 is connected to a main shaft 14, and the main shaft 14 is driven by a drive motor 19.

[0030] It should be understood that the material is fed into the compression chamber from the top. As the rotary support 12 swings, the material is dispersed into the inner wall area of ​​the ring die 11 under the action of centrifugal force. During the revolution of the pressure roller 13 with the rotary support 12, the roller surface forms a rolling contact with the inner wall of the sliding diaphragm, thereby generating rotation. During this process, the pressure roller 13 will roll the material into the discharge port 111. As the pressure roller 13 continues to revolve, the material gradually accumulates in the discharge port 111 until it is discharged from the outer end of the discharge port 111. At this time, the material presents a block structure due to compression.

[0031] This invention adds a cutting mechanism to the traditional ring die 11 briquetting machine and sets the receiving tray 16 to intermittent motion, which can effectively reduce equipment energy consumption and improve economic efficiency. Specifically, the cutting mechanism is installed on the outside of the ring die 11, and the cutting mechanism includes an annular cutter 15 that reciprocates along the axial direction of the ring die 11; the receiving tray 16 is rotatably disposed on the outside of the ring die 11 and located below the discharge port 111. The receiving tray 16 is drivenly connected to the main shaft 14, and a clutch mechanism is provided between the receiving tray 16 and the main shaft 14 so that the receiving tray 16 can rotate intermittently.

[0032] The cutting structure of the present invention can actively cut the material and wrap it into a uniform length. At the same time, the cutting structure can cooperate with the receiving tray 16. Before the receiving tray 16 starts to rotate each time, the cutting mechanism performs a cutting action to make the material fall completely. Then the receiving tray 16 discharges these materials in a concentrated manner, avoiding the receiving tray 16 being empty, improving the conveying efficiency of the receiving tray 16 during operation, and reducing the overall energy consumption of the equipment.

[0033] Please see Figure 3 , 4 As shown in Figures 6 and 7, in an optional embodiment of the present invention, a driving gear 141 is provided on the main shaft 14, and a driven gear 27 is provided on the bracket 18 below the base plate 10. The driven gear 27 is coaxially fixedly connected to the first pulley 26. The bracket 18 is also provided with a slide 23 that is radially movable along the main shaft 14. A second pulley 25 is provided on the slide 23. The second pulley 25 is coaxially fixedly connected to the drive roller 24. The second pulley 25 and the first pulley 26 are connected by a belt to form a transmission engagement. When the slide 23 slides, it can make the drive roller 24 fit or separate from the inner wall of the receiving tray 16. It should be understood that the present invention uses the drive roller 24 to drive the receiving tray 16 to rotate, rather than directly using gear transmission. The drive roller 24 and the receiving tray 16 are connected by friction transmission, which has a certain buffering function and can effectively avoid the receiving tray 16 from jerking each time it starts.

[0034] Please see Figure 7 As shown, in an optional embodiment of the present invention, the support 18 is further provided with a tension wheel 33, which is mounted on a movable frame 34. The movable frame 34 is movably connected to the support 18, and a first elastic element 35 is provided between the movable frame 34 and the support 18. The belt is arranged to pass around the tension wheel 33. It should be understood that the tension wheel 33 can ensure that the belt will not fall off the pulleys during the sliding process of the slide block 23.

[0035] Please see Figure 3 , 4As shown in Figures 6 and 7, in an optional embodiment of the present invention, the clutch mechanism includes a lifting support 20, a connecting rod 22 is hinged between the lifting support 20 and the slide 23, and the lifting support 20 is connected to a vertically arranged linear drive element 21. In this embodiment, the specific principle of the clutch mechanism is as follows: when the lifting support 20 moves downward, the slide 23 is pulled away from the receiving tray 16, at which point the drive roller 24 disengages from the receiving tray 16. When the lifting support 20 moves upward, the slide 23 is pushed closer to the receiving tray 16, at which point the drive roller 24 abuts against the receiving tray 16. When the drive roller 24 rotates, it drives the receiving tray 16 to rotate through friction.

[0036] Please see Figure 4 , 6 As shown in Figure 7, in an optional embodiment of the present invention, a linkage mechanism is provided between the clutch mechanism and the cutting mechanism. The linkage mechanism is configured such that when the clutch mechanism drives the drive roller 24 to fit against the inner wall of the receiving tray 16, the clutch mechanism can simultaneously drive the annular cutter 15 to rise a certain distance and then automatically fall to cut off the material outside the discharge port 111.

[0037] Specifically, the lower end of the annular cutter 15 is connected to a transmission plate 151. The linkage mechanism includes a column 28 fixedly connected to the lifting support 20. A movable stop 30 is provided at the upper end of the column 28. The movable stop 30 is slidably arranged along the radial direction of the column 28. A drive block 31 is also provided at the upper end of the column 28. The drive block 31 is slidably arranged along the axial direction of the column 28. A drive pin 32 is provided on the drive block 31. An inclined groove 301 that slidably engages with the drive pin 32 is provided on the movable stop 30. A second elastic element 29 is provided between the drive block 31 and the column 28. When the lifting support... When the lifting support 20 is in the low position within its stroke, the driving block 31 is pushed upward by the second elastic element 29. At this time, the movable stop block 30 can protrude below the transmission plate 151 so that the lifting support 20 can synchronously drive the annular cutter 15 to move upward during the lifting process. When the lifting support 20 is in the high position within its stroke, the driving block 31 abuts against the bottom surface of the base plate 10 so that the driving block 31 retracts downward relative to the column 28. At this time, the driving block 31 can drive the movable stop block 30 to be pulled away from the bottom of the transmission plate 151 so that the annular cutter 15 can be reset downward.

[0038] It should be understood that the present invention achieves coordinated action between the annular cutter 15 and the drive roller 24 through a linkage mechanism. During the process of the drive roller 24 and the receiving tray 16 being in contact, the clutch mechanism can first drive the annular cutter 15 to move upward once, and the cutter immediately resets after moving upward to avoid obstructing the discharge port 111. The linkage mechanism simplifies the equipment structure and reduces the equipment cost.

[0039] Please see Figure 4 As shown, in an optional embodiment of the present invention, a third elastic element 152 is further provided between the transmission plate 151 and the base plate 10. In some other alternative embodiments, the transmission plate 151 can also be reset by its own gravity, in which case the third elastic element 152 is not required.

[0040] Please see Figure 1 , 2 As shown in Figure 5, in an optional embodiment of the present invention, a surrounding wall 17 is further included. The surrounding wall 17 is disposed around the receiving tray 16, and a discharge port 171 is provided on the surrounding wall 17. An inclined plate 172 is provided at the discharge port 171, and the inclined plate 172 is fixedly connected to one side of the discharge port 171. The inclined plate 172 extends above the receiving tray 16 and is used to guide the material on the receiving tray 16 to the discharge port 171. During the rotation of the receiving tray 16, the material is blocked by the inclined plate 172 after reaching the discharge port 171, and is discharged from the discharge port 171 under the guidance of the inclined plate 172.

[0041] Please see Figure 5 As shown, in an optional embodiment of the present invention, the support 18 is provided with a plurality of vertical limiting rollers 181 and horizontal limiting rollers 182, and the lower end of the receiving tray 16 is provided with a limiting ring. The bottom of the limiting ring is supported by each of the horizontal limiting rollers 182, and the sidewall of the limiting ring is clamped by the plurality of vertical limiting rollers 181. The present invention uses horizontal limiting rollers 182 and vertical limiting rollers 181 to support the receiving tray 16, avoiding the use of large-diameter bearings and further reducing equipment costs.

[0042] Please see Figure 3 As shown, in an optional embodiment of the present invention, the main shaft 14 and the drive motor 19 are connected by a pulley mechanism, and the linear drive element 21 is an electric cylinder.

[0043] In summary, the cutting structure of this invention can actively cut materials, ensuring consistent material length. Simultaneously, the cutting structure can cooperate with the receiving tray 16. Before each rotation of the receiving tray 16, the cutting mechanism performs a cutting action to ensure sufficient material drop. The receiving tray 16 then collects and discharges these materials, preventing it from being idle and improving its conveying efficiency while operating, thus reducing overall equipment energy consumption. This invention uses a drive roller 24 to drive the receiving tray 16, rather than directly using gear transmission. The drive roller 24 and the receiving tray 16 are driven by friction, providing a buffering function and effectively preventing jerking during each start-up. This invention achieves coordinated action between the annular cutter 15 and the drive roller 24 through a linkage mechanism. During the contact process between the drive roller 24 and the receiving tray 16, the clutch mechanism first drives the annular cutter 15 upward once, and the cutter immediately resets after upward movement to avoid obstructing the discharge port 111. The linkage mechanism simplifies the equipment structure and reduces equipment costs.
