Description

Technical Field

[0001] The invention relates to the field of energy recycling, and in particular to raw material refinement processing equipment and a method for extracting fuel from white plastic waste. Background Art

[0002] With the widespread use of plastic products, the problem of handling white plastic waste is becoming increasingly serious. These wastes not only occupy a large amount of land resources, but also cause serious damage to the ecological environment. In order to effectively solve this problem, converting white plastic waste into fuel has become a feasible way to utilize resources.

[0003] However, in the process of achieving this goal, the refinement of raw materials has become a key technical problem. Traditional white plastic waste refinement methods often use a single crushing mechanism, resulting in low crushing efficiency and insufficient waste refinement. This not only increases the difficulty of subsequent processing, but also reduces the quality of the fuel.

[0004] Secondly, during the crushing process, due to the different shapes, sizes and materials of garbage, it is easy to cause blockage and stagnation, which not only affects the normal operation of the equipment, but also reduces the processing efficiency. Summary of the invention

[0005] In order to make up for the deficiencies of the existing technical problems, the purpose of the present invention is to provide a raw material refinement processing equipment and method for extracting fuel from white plastic waste, and the technical problems solved are as follows: how to efficiently refine and process white plastic waste, how to improve fuel quality and reduce energy consumption.

[0006] In order to solve the problems of the prior art, the technical solution of the present invention is as follows: Raw material refining processing equipment for extracting fuel from white plastic waste comprises an outer box, an upper hopper, an upper plate and a lower plate. The top of the outer box is fixedly connected to the upper hopper, the bottom of the outer box is fixedly connected to the lower plate, the interior of the outer box is located above the lower plate and is rotatably connected to the upper plate, the bottom of the upper plate is concave, the top of the lower plate is convex, the bottom of the upper plate is fixedly connected to a spiral strip, the top of the lower plate is equidistantly rotatably connected to a claw knife, the interior of the lower plate is rotatably connected to a rotating shaft, the top of the rotating shaft is fixedly connected to the upper plate, a motor is installed at the bottom of the outer box, and the output end of the motor is fixedly connected to the end corresponding to the rotating shaft.

[0007] Preferably, an annular slope is provided on the top of the lower plate, a feed pipe is fixedly connected to one side of the outer box, and the connection between the feed pipe and the outer box is arranged opposite to the lowest point of the annular slope.

[0008] Preferably, a feed hopper is provided on the top of the upper plate, feed ports are symmetrically opened inside the feed hopper, a bracket is fixedly connected inside the upper hopper, a fixed shaft is rotatably connected inside the feed hopper, and the top end of the fixed shaft is fixedly connected to the bracket.

[0009] Preferably, the inside of the feed port is symmetrically connected to crushing rollers for rotation, a driving bevel gear is fixedly connected to the outside of the bottom end of the fixed shaft, and driven bevel gears are meshingly connected on both sides of the driving bevel gear. The driven bevel gears are respectively fixedly connected to the outside of one end of the corresponding crushing rollers, and the other ends of the two crushing rollers inside the feed port are connected through a gear set.

[0010] Preferably, an installation groove is provided at the bottom of the lower plate, and a linkage rod is equidistantly slidably connected inside the lower plate. A connecting rod is provided on one side of the bottom end of the claw knife, and the top of the linkage rod is rotatably connected to the connecting rod. A sleeve is slidably connected to the outer side of the bottom end of the linkage rod, and a spring is provided inside the sleeve. The linkage rod is elastically connected to the sleeve through the spring.

[0011] Preferably, a rolling ball is provided at the bottom end of the sleeve, and a rotating plate is provided at the outside of the rotating shaft at the bottom of the lower plate. The rolling balls are rollingly connected to the rotating plate, a crest is provided on the top of the rotating plate, and lifting bars are equidistantly provided on the top of the lower plate, and the top end of the linkage rod is fixedly connected to the corresponding lifting bar.

[0012] Preferably, the feed hopper is rotatably connected to the bottom of the upper hopper, which not only makes the entire device more stable and firm, but also can use the surfaces of both to guide the garbage to gather at the feed inlet.

[0013] The processing method of the raw material refinement processing equipment for extracting fuel from white plastic waste includes the following steps: A. Loading: Pour the white plastic waste into the upper hopper. The waste enters the equipment and the gap between the upper and lower plates. Since the bottom of the upper plate is concave and the top of the lower plate is convex, the waste will first slide around in the gap.

[0014] B. Main crushing: The garbage is pushed by the spiral strips at the bottom of the upper plate and dispersed to the surroundings, so that the garbage is pushed to the claw knife for shredding. During the rotation of the shaft, the wave crest on the rotating plate drives the linkage rod to rise and fall intermittently, so that the claw knife has a downward cutting action, further enhancing the crushing effect.

[0015] C. Intermittent lifting and jacking: The lifting action of the linkage rod not only enables the claw knife to cut the garbage better, but also lifts up the garbage that may be stuck between the claw knives through the jacking bar, ensuring that the garbage can continue to be pushed by the spiral bar and cut by the claw knife. This process can ensure that the garbage is fully crushed inside the equipment to avoid blockage and retention.

[0016] D. Continuous crushing and discharge: The garbage is refined in the crushing area, and the fully crushed garbage is discharged from the equipment and prepared for subsequent processing.

[0017] E. Ending and cleaning: Stop the operation of the equipment, open the cleaning port of the equipment, clean up the remaining garbage and impurities, ensure the cleanliness and hygiene of the equipment, check the wear of each component of the equipment, and perform maintenance and replacement in time.

[0018] Compared with the prior art, the advantages of the present invention are as follows: 1. The present invention adopts a multi-stage crushing mechanism, including preliminary crushing and main crushing areas, to ensure that the white plastic waste is fully refined before entering the subsequent processing flow. The design of the claw knife and spiral strips optimizes the crushing effect and improves the crushing efficiency, so that the waste can be refined to a particle size suitable for extracting fuel in a short time.

[0019] 2. The present invention uses an intermittent lifting and jacking mechanism, and the equipment can effectively avoid the blockage and retention problems of garbage during the crushing process. The lifting action of the linkage rod not only helps the claw knife to cut the garbage better, but also can lift the garbage stuck between the claw knife through the jacking bar, ensuring the continuous flow and crushing of the garbage.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] The raw material refinement processing equipment for extracting fuel from white plastic waste comprises an outer box 1, an upper hopper 2, an upper plate 3 and a lower plate 4; like Figures 1 to 8 As shown, an upper hopper 2 is fixedly connected to the top of the outer box 1, a lower plate 4 is fixedly connected to the bottom of the outer box 1, an upper plate 3 is rotatably connected to the interior of the outer box 1 above the lower plate 4, the bottom of the upper plate 3 is concave, the top of the lower plate 4 is convex, a spiral strip 5 is fixedly connected to the bottom of the upper plate 3, a claw knife 6 is rotatably connected to the top of the lower plate 4 at an equal distance, a rotating shaft 7 is rotatably connected to the interior of the lower plate 4, the top of the rotating shaft 7 is fixedly connected to the upper plate 3, a motor 8 is installed at the bottom of the outer box 1, and the output end of the motor 8 is fixedly connected to the end corresponding to the rotating shaft 7; After the initial crushing, the garbage enters the gap between the upper plate 3 and the lower plate 4. Since the bottom of the upper plate 3 is concave and the top of the lower plate 4 is convex, the garbage will first slide around in the gap to avoid the accumulation of garbage in the gap. The spiral bars 5 at the bottom of the upper plate 3 are driven by the rotating shaft 7 to push the garbage to be dispersed around, and the garbage is continuously pushed to the edge of the claw knife 6 for further fine crushing of the garbage. The claw knife 6 is designed to be in the shape of a claw hook, which can better hook the garbage and improve the crushing effect.

[0031] like Figures 1 to 8 As shown, an annular slope 9 is opened on the top of the lower plate 4, and a discharge pipe 10 is fixedly connected to one side of the outer box 1. The connection between the discharge pipe 10 and the outer box 1 is arranged opposite to the lowest point of the annular slope 9. The garbage after being fully crushed is guided by the annular slope 9 on the top of the lower plate 4, gathered at the lowest point of the slope, and discharged from the equipment by the discharge pipe 10 for subsequent processing.

[0032] like Figures 1 to 8 As shown, a feed hopper 11 is provided on the top of the upper plate 3, and a feed port 12 is symmetrically opened inside the feed hopper 11. A bracket 13 is fixedly connected inside the upper hopper 2, and a fixed shaft 14 is rotatably connected inside the feed hopper 11. The top of the fixed shaft 14 is fixedly connected to the bracket 13. The garbage is first fed into the equipment through the upper hopper 2, and enters the gap between the upper plate 3 and the lower plate 4 along the feed port 12 of the feed hopper 11.

[0033] like Figures 1 to 8 As shown, the inside of the feed port 12 is symmetrically connected to the crushing rollers 15 for rotation, the outside of the bottom end of the fixed shaft 14 is fixedly connected to the driving bevel gear 16, and the two sides of the driving bevel gear 16 are meshed and connected to the driven bevel gears 17, and the driven bevel gears 17 are respectively fixedly connected to the outside of one end of the corresponding crushing rollers 15, and the other ends of the two crushing rollers 15 in the feed port 12 are connected by a gear set 18; The feed port 12 continuously adjusts its position as the upper plate 3 rotates. At the same time, the crushing roller 15 in the feed port 12 rotates around the fixed axis 14 through the driven bevel gear 17 and keeps rotating under the guidance of the driving bevel gear 16. Moreover, when one crushing roller 15 rotates, the other crushing roller 15 is driven to rotate through the gear set 18, ensuring that the garbage can be crushed in advance before entering the main crushing area. The crushing roller 15 can also be used to make it easier for the garbage to enter the gap between the upper plate 3 and the lower plate 4.

[0034] like Figures 1 to 8 As shown, a mounting groove 19 is provided at the bottom of the lower plate 4, and a linkage rod 20 is equidistantly slidably connected inside the lower plate 4. A connecting rod 21 is provided on one side of the bottom end of the claw knife 6. The top of the linkage rod 20 is rotatably connected to the connecting rod 21, and a sleeve 22 is slidably connected to the outer side of the bottom end of the linkage rod 20. A spring 23 is provided inside the sleeve 22, and the linkage rod 20 is elastically connected to the sleeve 22 through the spring 23. The claw knife 6 can be rotated to a certain extent by sliding the linkage rod 20 up and down. The lifting and lowering of the linkage rod 20 can make the claw knife 6 rotate to form a cutting action, which can further enhance the crushing effect of the garbage.

[0035] like Figures 1 to 8 As shown, a ball 24 is provided at the bottom of the sleeve 22, a rotating plate 25 is provided at the bottom of the lower plate 4 outside the rotating shaft 7, the ball 24 is rollingly connected with the rotating plate 25, a crest is provided at the top of the rotating plate 25, and a lifting bar 26 is equidistantly provided at the top of the lower plate 4, and the top of the linkage rod 20 is fixedly connected with the corresponding lifting bar 26; Driven by the motor 8, the rotating shaft 7 not only drives the upper plate 3 and the spiral bar 5 to rotate, but also guides the rolling ball 24 through the wave crest on the rotating plate 25 to make the linkage rod 20 rise and fall intermittently. The lifting action of the linkage rod 20 not only makes the claw knife 6 cut down, thereby enhancing the crushing effect, but also can lift up the garbage that may be stuck between the claw knives 6 through the lifting bar 26, ensuring that the garbage can continue to be pushed by the spiral bar 5 and cut by the claw knife 6.

[0036] like Figures 1 to 8 As shown, the feed hopper 11 is rotatably connected to the bottom of the upper hopper 2. The connection between the feed hopper 11 and the upper hopper 2 can not only make the entire device more stable and firm, but also use the surfaces of both to guide the garbage to gather at the feed port 12.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
