Abstract
Description
Technical Field
[0001] This utility model relates to the field of pyrolysis machine feeding technology, and more specifically, to a pyrolysis machine feeding device. Background Technology
[0002] During the feeding process of traditional pyrolysis machines, the waste material often contains debris and sand particles, causing jamming or wear on the screw conveyor components and affecting the equipment's lifespan. Existing technologies mostly use fixed screens to separate impurities, but this results in low screening efficiency, easy clogging, and frequent shutdowns for cleaning. Some solutions use vibrating motors to drive the screens, which can alleviate clogging, but suffers from high energy consumption, complex structure, and poor vibration transmission, failing to completely separate fine particles. This leads to accelerated wear on the subsequent screw plate and feed plate, increasing maintenance costs.
[0003] Existing screw conveyor devices are mostly single-shaft structures, which make it easy for materials to accumulate at the inlet. Manual intervention is required to adjust the flow rate, making it difficult to achieve uniform and quantitative conveying. In addition, the screening and conveying units usually operate independently without coordinated control. The mismatch between material separation and pushing rhythm can easily cause intermittent blockage or idling. Some improved designs attempt to increase the screen vibration frequency, but they ignore the linkage between automatic reset and impact clearing, resulting in insufficient equipment stability and difficulty in adapting to the needs of high-load continuous operation, which restricts the improvement of pyrolysis efficiency. Therefore, in order to address the above technical problems, a pyrolysis machine feeding device is proposed here. Utility Model Content

[0027] Example
[0028] This application discloses a pyrolysis machine feeding device, including a main body 1, a partition plate 6, and a feed inlet 17. The main body 1 serves as the basic support structure for the entire device, and an internally fixed vertical plate 2 is used to strengthen the overall rigidity and serve as the mounting base for other components. Figure 2 as well as Figure 3 As shown, an inclined plate 3 is fixedly connected between the upper side of the vertical plate 2 and the interior of the main body 1 of the device. The inclined plate 3 is installed at an angle to facilitate the natural sliding of materials by gravity. A filter screen 4 is provided on the outside of the inclined plate 3 to separate materials from impurities. A feed hopper 5 is fixedly connected to the upper side of the main body 1 as the main inlet for materials. The feed hopper 5 is installed on the upper surface of the main body 1, near the higher side of the inclined plate 3. This arrangement facilitates the smooth entry of materials into the area of the inclined plate 3.
[0029] The partition 6 is slidably connected to the upper side of the main body 1 of the device and can move up and down in the vertical direction. A positioning plate 7 is fixedly connected to one side of the upright plate 2 to limit the movement trajectory of the partition 6. The partition 6 abuts against the upper side of the positioning plate 7 to form an initial position. Figure 2 as well as Figure 4 As shown, a first fixing plate 8 and a second fixing plate 9 are fixedly connected to the top two sides of the partition 6. A tension spring 10 is fixedly connected between the lower side of the first fixing plate 8 and the upper side of the device body 1. The tension spring 10 provides the partition 6 with the reset power and maintains its initial contact state with the positioning plate 7.
[0030] A lifting mechanism is installed on one side of the second fixed plate 9. This lifting mechanism includes a mounting plate 11, a first motor 12, a rotating rod 13, and a stop plate 14. The mounting plate 11 is fixedly connected to the upper side of the device body 1 as a support frame, and there are two sets of mounting plates 11 arranged horizontally to ensure structural stability. Figure 1 , Figure 2 as well as Figure 4 As shown, the first motor 12 is fixedly connected to the outside of one set of mounting plates 11 as a power source. The rotating rod 13 is rotatably connected between the two sets of mounting plates 11 to form a transmission shaft, and the rotating rod 13 and the first motor 12 are fixedly connected to achieve power transmission. The abutment plate 14 is fixedly connected to the outside of the rotating rod 13 as an actuator, and there are several sets of abutment plates 14 arranged in a ring to form a continuous working surface. The abutment plate 14 abuts against the second fixed plate 9 to achieve a periodic lifting action.
[0031] An opening 15 is provided on the side of the main body 1 near the inclined plate 3 as an impurity discharge channel. A rotating plate 16 is rotatably connected inside the opening 15 to control its opening and closing. A feed inlet 17 is located on one side of the main body 1 as a material outlet. A feed plate 18 is fixedly connected to the outside of the feed inlet 17 to form a material conveying channel. A screw extrusion mechanism is installed on the inner bottom of the main body 1 to achieve the material propulsion function, such as... Figure 2 Figure 5 as well as Figure 6 As shown, the spiral extrusion mechanism includes a second motor 19, a rotating shaft 20, and a spiral plate 21. The second motor 19 is fixedly connected to one side of the vertical plate 2 to provide driving force. The rotating shaft 20 is fixedly connected to one side of the second motor 19 as a transmission component, and the rotating shaft 20 and the vertical plate 2 are rotatably connected to ensure operational stability. The spiral plate 21 is fixedly connected to the outside of the rotating shaft 20 to realize the material pushing function, and multiple spiral extrusion mechanisms are installed and arranged laterally to improve conveying efficiency. The feed plate 18 has a hollow plate structure to form a material channel, and the spiral plate 21 is tangent to the upper and lower inner surfaces of the feed plate 18 to ensure conveying effect and prevent material residue.
[0032] like Figure 6 As shown, a housing 22 is fixedly connected to one side of the upright plate 2 for protection and sealing, and the housing 22 encloses the second motor 19 for protection. Figure 1 As shown, a PLC processor 23 is fixedly connected to the outside of the main body 1 of the device as the control core, and the PLC processor 23 is electrically connected to the first motor 12 and the second motor 19 to realize automated control.
[0033] The working principle of the pyrolysis machine feeding device according to the embodiment is as follows: When the pyrolysis waste enters the main body 1 of the device through the feeding hopper 5, the material first slides down along the inclined plate 3. At this time, the first motor 12 of the lifting mechanism drives the rotating rod 13 to rotate, which drives the outer ring-arranged abutment plate 14 to periodically push the second fixed plate 9 of the partition plate 6, so that the partition plate 6 overcomes the tension of the tension spring 10 and rises upward. When the abutment plate 14 disengages from the second fixed plate 9, the partition plate 6 falls rapidly under the contraction force of the tension spring 10 and its own gravity, and collides with the positioning plate 7 on the side of the vertical plate 2. The resulting impact vibration is transmitted to the inclined plate 3 and the filter screen 4 on its surface, causing the debris and sand particles in the waste to pass through. The filter screen 4 separates and falls through the holes, effectively avoiding wear caused by hard particles on the spiral plate 21 and the feed plate 18 during subsequent processing. When the first motor 12 runs continuously, the partition 6 forms a regular vibration in a cyclic lifting mode, maintaining the continuous screening effect of the filter screen 4. At the same time, it can also achieve uniform quantitative feeding. In conjunction with the spiral extrusion mechanism, the second motor 19 drives the rotating shaft 20 and the outer spiral plate 21 to rotate, pushing the filtered material from the feed port 17 along the hollow feed plate 18 to the next process. Multiple sets of horizontally arranged spiral plates 21 are tightly tangent to the inner wall of the feed plate 18, forming a stable quantitative conveying channel, which can prevent material accumulation or blockage.
