Description

Technical Field

[0001] This invention relates to the field of waste conveying technology, and more particularly to a spiral conveyor device for waste treatment. Background Technology

[0002] A screw conveyor is a machine that uses a motor to drive a screw to rotate, pushing materials to achieve the purpose of conveying. It can convey horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance and convenient closed transportation. Screw conveyors are divided into two types in terms of conveying form: shafted screw conveyors and shaftless screw conveyors. In terms of appearance, they are divided into U-shaped screw conveyors and tubular screw conveyors.

[0003] Screw conveyors are widely used in waste management. However, in the current technology, screw conveyors are prone to problems such as inlet blockage (bridging) and large dust and airflow interference when dealing with loose waste, resulting in low waste conveying efficiency and high energy consumption.

[0004] In view of this, the present invention proposes a spiral conveyor for waste disposal to solve the problems existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a spiral conveyor device for waste disposal.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spiral conveyor for waste disposal includes a spiral conveyor with a feed pipe, a feed hopper on the feed pipe, an L-shaped mounting bracket on one side of the feed hopper, and a rotating column rotatably connected to the L-shaped mounting bracket. The lower part of the rotating column extends into the feed hopper and is coaxial. A drive cavity is provided inside the lower part of the rotating column. Multiple pairs of drive shafts are evenly spaced on the outer wall of the drive cavity. Each pair of drive shafts has a notch on its outer wall, and a fan-shaped pressing plate is fixedly connected to each notch. A connecting column is fixedly connected to one side of the outer wall of each pair of drive shafts, and two meshing drive gears are fixedly connected to the outer walls of the two connecting columns. A drive rotation mechanism is provided inside the drive cavity.

[0008] Furthermore, a transmission wheel is fixedly connected to the outer wall above the rotating column, a servo motor is fixedly connected to the outer wall of the L-shaped mounting bracket, and a transmission wheel is fixedly connected to the output shaft end of the servo motor. A transmission belt is sleeved on the outer wall of the transmission wheel and the transmission wheel.

[0009] Furthermore, the drive rotation mechanism includes an electric push rod two, which is fixedly connected to the inner wall of the top of the drive cavity, and the telescopic end of the electric push rod two is fixedly connected to a lifting plate.

[0010] Furthermore, four racks are fixedly connected at equal intervals on the bottom outer wall of the lifting plate, and each rack meshes with a corresponding drive gear.

[0011] Furthermore, a rotating shaft is rotatably connected to the inner wall of the drive cavity, and a turntable is fixedly connected to one end of the rotating shaft. A second drive gear is fixedly connected to the outer wall of the rotating shaft.

[0012] Furthermore, a rack is fixedly connected to the bottom outer wall of the lifting plate, and the rack meshes with the drive gear.

[0013] Furthermore, a telescopic rod is slidably connected to the bottom of the drive cavity, and a tamping ball is fixedly connected to the bottom end of the telescopic rod. The tamping ball is located directly above the feed pipe, and a vertical push plate is hinged between the top end of the telescopic rod and the outer wall of the turntable.

[0014] Furthermore, a ring is slidably connected to the outer wall of the rotating column, and two fixing plates are symmetrically fixedly connected to the top outer wall of the ring. Two electric push rods are symmetrically installed on the L-shaped mounting bracket, and the telescopic ends of the electric push rods are fixedly connected to the corresponding fixing plates.

[0015] Furthermore, the outer wall above the rotating column is provided with multiple receiving slots at equal intervals, and the inner wall above each receiving slot is rotatably connected to a lifting plate by a torsion spring, the lower end of the lifting plate being in contact with the outer wall of the ring.

[0016] The beneficial effects of this invention are as follows:

[0017] The rotating fan-shaped pressing plate compresses the waste, effectively reducing volume and venting, improving the efficiency of the screw conveyor and reducing energy consumption; the synchronous ball compaction and material picking mechanism ensures smooth and unobstructed feeding, significantly enhancing the stability and reliability of waste treatment.

[0026] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0027] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6A screw conveyor for waste disposal includes a screw conveyor 1 with a feed pipe 3, a feed hopper 2 on the feed pipe 3, an L-shaped mounting bracket 9 on one side of the feed hopper 2, and a rotating column 4 rotatably connected to the L-shaped mounting bracket 9. The lower part of the rotating column 4 extends into the feed hopper 2 and is coaxial. A drive chamber 17 is provided inside the lower part of the rotating column 4. Multiple pairs of drive shafts 18 are evenly spaced on the outer wall of the drive chamber 17, and each pair of drive shafts 18 has a notch 24 on its outer wall. A fan-shaped button is fixedly connected to each notch 24. The pressure plate 19 has a connecting column 25 fixedly connected to one side of the outer wall of each pair of drive shafts 18, and each pair of connecting columns 25 has a meshing drive gear 26 fixedly connected to its outer wall. The drive cavity 17 is equipped with a drive rotation mechanism. The initial state of the rotating column 4 is that the fan-shaped pressing plates 19 on each pair of drive shafts 18 are joined together. At this time, the gap between each pair of drive shafts 18 is at its maximum, so that the outside can dump garbage into the feed hopper 2. After the garbage is dumped, the drive rotation mechanism in the drive cavity 17 starts to start, so that each pair of One of the drive gears 26 on the drive shaft 18 rotates. Since the two drive gears 26 on each pair of drive shafts 18 mesh with each other, when one drive gear 26 rotates, the other drive gear 26 rotates simultaneously, and the two drive gears 26 rotate in opposite directions, thereby driving the drive shaft 18 to rotate. The drive shaft 18 causes the combined fan-shaped pressing plates 19 to separate. The fan-shaped pressing plates 19 rotate downward around the axis of the drive shaft 18. During this process, the fan-shaped pressing plates 19 press and compress the garbage in the feed hopper 2. In the process of compression, the garbage can be pushed into the feed pipe 3 and finally into the screw conveyor 1. Through the above process, the garbage can be pre-compressed, greatly reducing the volume of the garbage and avoiding the material being too loose, which would lead to low conveying efficiency and high energy consumption of the screw conveyor 1. At the same time, the pressing of the fan-shaped pressing plates 19 can expel most of the air in advance, so that the material enters the screw conveyor 1 in a denser solid form, making the conveying process more stable and controllable, and reducing dust and airflow interference.

[0028] Reference Figure 2As a further embodiment of the present invention, a transmission wheel 5 is fixedly connected to the outer wall above the rotating column 4, and a servo motor 8 is fixedly connected to the outer wall of the L-shaped mounting bracket 9. A transmission wheel 7 is fixedly connected to the output shaft end of the servo motor 8. A transmission belt 6 is sleeved on the outer wall of the transmission wheel 5 and the transmission wheel 7. The servo motor 8 can rotate the rotating column 4 through the transmission cooperation of the transmission wheel 7, the transmission wheel 5, and the transmission belt 6, thereby causing the fan-shaped pressing plate 19 to rotate with the rotating column 4. When the garbage enters the narrow feed pipe 3, it is very easy for "bridging" to occur, that is, the garbage gets stuck at the entrance and cannot fall smoothly. The forced pressing and stirring action of the fan-shaped pressing plate 19 can break this arch structure, ensuring that the garbage continuously and evenly enters the feed pipe 3, providing a stable material flow for the screw conveyor 1, so that the equipment can operate smoothly.

[0029] Reference Figure 5 and Figure 7 As a further embodiment of the present invention, the drive rotation mechanism includes an electric push rod 20, which is fixedly connected to the top inner wall of the drive cavity 17, and the telescopic end of the electric push rod 20 is fixedly connected to a lifting plate 21, which enables the lifting plate 21 to move up and down.

[0030] Reference Figure 7 As a further embodiment of the present invention, four racks 28 are fixedly connected at equal intervals on the bottom outer wall of the lifting plate 21, and each rack 28 meshes with a corresponding drive gear 26, thereby driving the racks 28 to move synchronously. Since each rack 28 meshes with one of the drive gears 26 on each pair of drive shafts 18, the drive shaft 18 can rotate when the racks 28 move up and down, causing the fan-shaped pressing plate 19 in the notch 24 to rotate downward or upward.

[0031] Working principle: In the initial state of the rotating column 4, the fan-shaped pressing plates 19 on each pair of drive shafts 18 are joined together, and the gap between each pair of drive shafts 18 is at its maximum, allowing external waste to be dumped into the feed hopper 2. After the waste is dumped, the drive rotation mechanism in the drive chamber 17 starts, causing one of the drive gears 26 on each pair of drive shafts 18 to rotate. Since the two drive gears 26 on each pair of drive shafts 18 are meshed, when one drive gear 26 rotates, the other drive gear 26 rotates simultaneously, and the two drive gears 26 rotate in opposite directions, thereby driving the drive shaft 18 to rotate. Through the drive shaft 18, the joined fan-shaped pressing plates 19 are rotated together. The pressing plate 19 separates, and the fan-shaped pressing plate 19 rotates downward around the axis of the drive shaft 18. During this process, the fan-shaped pressing plate 19 presses and compresses the garbage in the feed hopper 2. In the process of compression, it can push the garbage into the feed pipe 3 and finally into the screw conveyor 1. Through the above process, the garbage can be pre-compressed, greatly reducing the volume of the garbage and avoiding the material being too loose, which would result in low conveying efficiency and high energy consumption of the screw conveyor 1. At the same time, the pressing of the fan-shaped pressing plate 19 can expel most of the air in advance, so that the material enters the screw conveyor 1 in a denser solid form, making the conveying process more stable and controllable, and reducing dust and airflow interference.

[0032] Reference Figure 5 and Figure 7 As a further embodiment of the present invention, a rotating shaft 27 is rotatably connected to the inner wall of the drive cavity 17, and a turntable 23 is fixedly connected to one end of the rotating shaft 27, and a drive gear 29 is fixedly connected to the outer wall of the rotating shaft 27.

[0033] Reference Figure 5 and Figure 7 As a further embodiment of the present invention, a rack 22 is fixedly connected to the bottom outer wall of the lifting plate 21, and the rack 22 meshes with the drive gear 29. When the lifting plate 21 moves downward or upward, it will drive the rack 22 to move synchronously. Since the rack 22 meshes with the drive gear 29 on the outer wall of the rotating shaft 27, the rotating shaft 27 can rotate the turntable 23 in this process.

[0034] Reference Figure 2 , Figure 5 and Figure 7 As a further embodiment of the present invention, a telescopic rod 11 is slidably connected to the bottom of the drive cavity 17, and a tamping ball 10 is fixedly connected to the bottom end of the telescopic rod 11. The tamping ball 10 is located directly above the feed pipe 3. A vertical push plate 30 is hinged between the top end of the telescopic rod 11 and the outer wall of the turntable 23, thereby enabling the telescopic rod 11 to move up and down reciprocally. The tamping ball 10 applies force to press the garbage in the feed pipe 3, ensuring that the garbage in the feed pipe 3 can smoothly enter the screw conveyor 1.

[0035] Reference Figure 3 and Figure 4 As a further embodiment of the present invention, a ring 13 is slidably connected to the outer wall of the rotating column 4, and two fixing plates 14 are symmetrically fixed to the top outer wall of the ring 13. Two electric push rods 12 are symmetrically installed on the L-shaped mounting bracket 9, and the telescopic ends of the electric push rods 12 are fixedly connected to the corresponding fixing plates 14. The ring 13 can be moved upward by the electric push rods 12.

[0036] Reference Figure 3 and Figure 4 As a further embodiment of the present invention, multiple receiving slots 15 are provided at equal intervals on the outer wall above the rotating column 4, and the inner wall above each receiving slot 15 is rotatably connected to a pick plate 16 by a torsion spring. The lower end of the pick plate 16 contacts the outer wall of the ring 13, thereby enabling the pick plate 16 to rotate upward around its connection point. When garbage is placed on the two fan-shaped pressing plates 19 that are moving away from each other, the pick plate 16 can pick up the garbage and let it fall into the feed hopper 2.

[0037] Working principle: When the lifting plate 21 moves down or up, it drives the rack 22 to move synchronously. Because the rack 22 meshes with the drive gear 29 on the outer wall of the rotating shaft 27, the rotating shaft 27 can rotate the turntable 23 during this process. Because the top of the telescopic rod 11 is hinged to the outer wall of the turntable 23, the telescopic rod 11 can be pushed to move up and down reciprocally. The tamping ball 10 applies force to press the garbage in the feed pipe 3, ensuring that the garbage in the feed pipe 3 can smoothly enter the screw conveyor 1. The electric push rod 12 can make the ring 13 move upward. Because the lower end of the pick plate 16 is in contact with the outer wall of the ring 13, the pick plate 16 can rotate upward around its connection point when the ring 13 moves upward. When garbage is placed on the two fan-shaped pressing plates 19 that are moving away from each other, the pick plate 16 can pick up the garbage and let it fall into the feed hopper 2.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
