Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling and screening, in particular to a recycling processing device and a recycling method for plastic fragments by vibration screening. Background Art

[0002] The working part of the drum screen is cylindrical, and the whole screen rotates around the axis of the drum. The axis is usually installed at a small inclination angle. The speed of the drum screen is very low, the operation is stable, and the dynamic balance is good. The drum screen is a vibration screening mechanical equipment that uses the relative movement between the bulk material and the screen surface to allow some particles to pass through the screen holes and classify the material into different grades according to the particle size. It is generally used to screen out impurities.

[0003] In the existing drum screen, such as Chinese patent application CN114029224A, the coordinated use of the drum screen, mounting rod, motor and stirring rod facilitates the stirring of the material during the sliding screening, thereby effectively improving the screening efficiency and practicality of the equipment, and the inclined setting of the drum screen can ensure the uniform flow of the material in the drum screen, thereby reducing the problem of poor screening and separation quality caused by material accumulation. Secondly, the setting of the sealing cover plate, the impurity discharge pipe and the sack facilitates the filtering and collection of the impurities screened by the material and the generated dust, which is convenient for the subsequent unified cleaning on the one hand, and avoids the pollution problem of the processing environment caused by dust on the other hand, thereby improving the convenience and practicality of the equipment.

[0004] However, there are still the following problems: if the size of the granular material happens to match the size of the sieve holes of the drum screen, the granular material will mostly get stuck in the sieve holes. At the same time, the drum screen is basically equipped with a vibration motor. With the vibration, the granular material may get stuck tighter and tighter in the sieve holes. After long-term operation, the screening capacity of the drum screen will be greatly reduced, affecting the normal operation of the drum screen. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a recycling and processing equipment and a recycling method for vibrating and screening plastic fragments.

[0032] Example 1

[0033] In a typical implementation of the present application, Figure 1 As shown, a recycling and processing equipment includes a body 1, a screening mechanism 2 arranged on the body 1, and an auxiliary mechanism 3 arranged on the body 1, the screening mechanism 2 includes a screening drum 24, a first material discharge chute 25, and a second material discharge chute 26, the body 1 is rotatably matched with the screening drum 24, the body 1 is tilted, the axis of the screening drum 24 is parallel to the bottom surface of the body 1, the first material discharge chute 25 is fixedly installed at the bottom end of the body 1, the second material discharge chute 26 is fixedly installed at the bottom end of the body 1, the first material discharge chute 25 is located above the second material discharge chute 26, the first material discharge chute 25 is adjacent to the discharge end of the screening drum 24, and the second material discharge chute 26 is opposite to the discharge end of the body 1;

[0034] The auxiliary mechanism 3 also includes an insert 34 and a crankshaft 36. A plurality of inserts 34 are arranged on the machine body 1. The inserts 34 are evenly distributed in a straight line. The inserts 34 are located directly below the screening drum 24. The straight line along which the inserts 34 are distributed is parallel to the axis of the screening drum 24. A plurality of crankshafts 36 are arranged on the machine body 1. Each crankshaft 36 is located directly below each insert 34. Each crankshaft 36 is power-connected to each crankshaft 36 so that the crankshaft 36 drives the insert 34 to reciprocate up and down. The moving trajectory of the insert 34 covers the sieve holes of the screening drum 24.

[0035] When using the present invention:

[0036] Plastic fragments are fed into the screening cylinder 24 from above. Start the rotation of the screening cylinder 24. With the rotation and inclined setting of the screening cylinder 24, the plastic fragments slide in the screening cylinder 24 and are subjected to screening treatment. The screened plastic fragments fall into the machine body 1. Then, the plastic fragments in the screening cylinder 24 will slide into the first blanking chute 25 and be discharged. The plastic fragments in the machine body 1 will slide into the second blanking chute 26 and be discharged. At the same time, the rotation of the screening cylinder 24 synchronously drives the crankshaft 36 to rotate. The crankshaft 36 drives the insertion piece 34 to move up and down reciprocally, so that the insertion piece 34 reciprocally inserts into the screen holes of the screening cylinder 24, preventing the plastic fragments from blocking in the screen holes of the screening cylinder 24. Thus, during the screening process of the equipment, the screen holes of the cylindrical screen are cleaned in real time, ensuring the screening quality of the cylindrical screen, preventing the reduction of screening efficiency caused by excessive blockage, and improving the stability of equipment use.

The bracket 21 is located directly below the machine body 1. A plurality of first telescopic rods 22 are provided on the bracket 21. The fixed rod of the first telescopic rod 22 is fixedly connected to the bracket 21, and the extending rod of the first telescopic rod 22 is fixedly connected to the machine body 1. A first spring 23 is sleeved on each first telescopic rod 22. One end of the first spring 23 is connected to the fixed rod of the first telescopic rod 22, and the other end of the first spring 23 is connected to the extending rod of the first telescopic rod 22.

The top end of the screening cylinder 24 is the feeding end, and the bottom end of the screening cylinder 24 is the discharging end. The inclination angle of the first blanking chute 25 is the same as the inclination angle of the screening cylinder 24, so that the plastic fragments screened out inside the screening cylinder 24 fall into the first blanking chute 25. The blanking plane of the second blanking chute 26 is in the same plane as the bottom surface inside the machine body 1. The bottom end of the first blanking chute 25 faces one side of the machine body 1, and the bottom end of the second blanking chute 26 faces the other side of the machine body 1.

[0040] Furthermore, a servo motor 27 is fixedly installed on the machine body 1. A traction wheel 28 is fixedly installed on the shaft of the servo motor 27. A driven wheel 29 is fixedly installed on the shaft of the screening cylinder 24. The traction wheel 28 is located directly below the driven wheel 29, and a belt 210 is tensioned between the traction wheel 28 and the driven wheel 29.

[0041] Among them, when screening plastic fragments, the servo motor 27 is started. The servo motor 27 drives the traction wheel 28 to rotate. The traction wheel 28 drives the belt 210 to rotate. The belt 210 drives the driven wheel 29 to rotate. The driven wheel 29 drives the screening cylinder 24 to rotate on the machine body 1, so that the screening cylinder 24 screens the plastic fragments. The screened plastic fragments fall into the machine body 1. Then, the plastic fragments remaining in the screening cylinder 24 slide into the first blanking chute 25 for discharge. The screened plastic fragments slide into the second blanking chute 25 from the machine body 1 for discharge.

[0042] Furthermore, a bearing 211 is sleeved on the screening cylinder 24. The inner ring of the bearing 211 is fixedly connected to the screening cylinder 24.

The connecting frame 212 is movably matched with the machine body 1. There is no gap between the connecting frame 212 and the machine body 1. The bottom end of the connecting frame 212 is located below the machine body 1. A vibration motor 213 is fixedly installed on the bottom end of the connecting frame 212.

[0043] Among them, while screening the plastic fragments, the vibration motor 213 is started. The vibration motor 213 drives the connecting frame 212 to vibrate. The connecting frame 212 drives the bearing 211 to vibrate. The bearing 211 drives the screening cylinder 24 to vibrate, so as to disperse the accumulation of plastic fragments in the screening cylinder 24 and improve the screening efficiency of the screening cylinder 24. And the vibration amplitude of the vibration motor 213 is small and cannot affect the movement of the insert piece 34 into the screen holes of the screening cylinder 24.

[0044] Furthermore, a feed chute 214 is arranged at the top end of the machine body 1. The top end of the feed chute 214 is connected to the feeder, so that the plastic fragments conveyed by the feeder fall into the feed chute 214. The bottom end of the feed chute 214 faces the feed end of the screening cylinder 24. The bottom end of the feed chute 214 is adjacent to the feed end of the screening cylinder 24. A fan 215 is fixedly installed on the machine body 1. The air outlet of the fan 215 faces the feed chute 214. A wind guide cylinder 216 is fixedly installed on the air outlet of the fan 215. The wind guide cylinder 216 is connected and communicated with the air outlet of the fan 215. The wind guide cylinder 216 faces the feed chute 214.

[0045] Among them, when feeding plastic fragments into the screening cylinder 24, the plastic fragments fall from the conveying equipment into the feed chute 214. The fan 215 is started. The air flow blown by the fan 215 is positioned and guided to the feed chute 214 from the wind guide cylinder 216, so that the air flow blows the plastic fragments in the feed chute 214. And the blowing air is small to blow out the smaller and lighter impurities in the plastic fragments.

[0046] Embodiment 3

[0047] Such as Figure 5-Figure 8As shown, the difference from the above embodiment is that the auxiliary mechanism 3 also includes a piston cylinder 31, a plurality of piston cylinders 31 are arranged on the body 1, and the piston cylinders 31 are evenly distributed on the inner bottom surface of the body 1 in a straight line, and the piston cylinders 31 are slidably fitted with piston rods 32, and the piston rods 32 penetrate the piston cylinders 31, and the top of the piston rods 32 are provided with second telescopic rods 33, and the fixed rods of the second telescopic rods 33 are fixedly connected to the piston rods 32, and the extension rods of the second telescopic rods 33 are fixedly installed with inserts 34, and the second telescopic rods 33 are sleeved with second springs 35, and one end of the second springs 35 is connected to the fixed rods of the second telescopic rods 33, and the other end of the second springs 35 is connected to the extension rods of the second telescopic rods 33.

[0048] Furthermore, a plurality of crankshafts 36 are rotatably engaged with the inner bottom surface of the machine body 1, and the crankshafts 36 and the piston rods 32 are evenly arranged in a straight line, and a loop frame 37 is provided between the crankshafts 36 and the piston rods 32, and one end of the loop frame 37 is rotatably engaged with the bottom end of the piston rod 32, and the other end of the loop frame 37 is rotatably engaged with two adjacent crankshafts 36, so that the crankshaft 36 as a whole is movably engaged with the other end of each loop frame 37.

[0049] Furthermore, a pulley 38 is fixedly mounted on one end of the integral crankshaft 36 and on the shaft of the screening drum 24 . The two pulleys 38 are opposed to each other up and down, and a toothed belt 39 is tensioned on the two pulleys 38 .

[0050] Among them, when the sieve holes of the screening drum 24 are cleaned, the rotation of the screening drum 24 drives the pulley 38 on the shaft of the screening drum 24 to rotate, the pulley 38 drives the toothed belt 39 to rotate, the toothed belt 39 drives the pulley 38 below to rotate, the pulley 38 below drives the crankshaft 36 to rotate, the crankshaft 36 drives the loop frame 37 to rotate, the loop frame 37 drives the piston rod 32 to reciprocate up and down in the piston cylinder 31, the piston rod 32 drives the second telescopic rod 33 to move, the second telescopic rod 33 drives the insert 34 to move, so that the insert 34 is reciprocatedly inserted into the sieve holes of the screening drum 24 for cleaning, and when the insert 34 hits the wall of the screening drum 24, the insert 34 pushes the second telescopic rod 33 to contract, and the second spring 35 is compressed to protect the insert 34 from damage, thereby ensuring the stability of the equipment operation.

[0051] The overall working principle of recycling equipment:

[0052] The plastic fragments are fed into the screening drum 24 from above, and the screening drum 24 is started to rotate. With the rotation of the screening drum 24 and the tilting setting of the screening drum 24, the plastic fragments slide in the screening drum 24 and are screened. The screened plastic fragments fall into the machine body 1, and then the plastic fragments in the screening drum 24 slide into the first unloading chute 25 for discharge, and the plastic fragments in the machine body 1 slide into the second unloading chute 26 for discharge. At the same time, the rotation of the screening drum 24 synchronously drives the crankshaft 36 to rotate, and the crankshaft 36 drives the insert 34 to move up and down, so that the insert 34 reciprocates and inserts into the sieve holes of the screening drum 24, so that the plastic fragments cannot be blocked in the sieve holes of the screening drum 24, so that the sieve holes of the cylindrical screen are cleaned in real time with the screening process of the equipment, so as to ensure the screening quality of the cylindrical screen, prevent the screening efficiency from being reduced due to excessive blockage, and improve the stability of the equipment.

[0053] When the plastic fragments are screened, the servo motor 27 is started, the servo motor 27 drives the traction wheel 28 to rotate, the traction wheel 28 drives the belt 210 to rotate, the belt 210 drives the driven wheel 29 to rotate, and the driven wheel 29 drives the screening drum 24 to rotate on the machine body 1, so that the screening drum 24 screens the plastic fragments, and the screened plastic fragments fall into the machine body 1, and then the plastic fragments remaining in the screening drum 24 slide into the first unloading chute 25 for discharge, and the screened plastic fragments slide from the machine body 1 into the second unloading chute 25 for discharge;

[0054] While the plastic fragments are being screened, the vibration motor 213 is started, the vibration motor 213 drives the connecting frame 212 to vibrate, the connecting frame 212 drives the bearing 211 to vibrate, and the bearing 211 drives the screening drum 24 to vibrate, so as to disperse the accumulation of the plastic fragments in the screening drum 24 and improve the screening efficiency of the screening drum 24. In addition, the vibration amplitude of the vibration motor 213 is small and cannot affect the movement of the insert 34 into the sieve hole of the screening drum 24.

[0055] When plastic fragments are fed into the screening drum 24, the plastic fragments fall from the conveying device into the feed chute 214, and the fan 215 is started. The wind flow blown by the fan 215 is positioned and directed from the air guide tube 216 to the feed chute 214, so that the wind flow blows the plastic fragments in the feed chute 214, and the blowing wind is small, so as to blow out the smaller and lighter impurities in the plastic fragments;

[0056] When cleaning the sieve holes of the screening drum 24, the rotation of the screening drum 24 drives the pulley 38 on the shaft of the screening drum 24 to rotate, the pulley 38 drives the toothed belt 39 to rotate, the toothed belt 39 drives the pulley 38 below to rotate, the pulley 38 below drives the crankshaft 36 to rotate, the crankshaft 36 drives the loop frame 37 to rotate, the loop frame 37 drives the piston rod 32 to reciprocate up and down in the piston cylinder 31, the piston rod 32 drives the second telescopic rod 33 to move, the second telescopic rod 33 drives the insert 34 to move, so that the insert 34 is reciprocatedly inserted into the sieve holes of the screening drum 24 for cleaning, and when the insert 34 hits the wall of the screening drum 24, the insert 34 pushes the second telescopic rod 33 to contract, and the second spring 35 is compressed to protect the insert 34 from damage, thereby ensuring the stability of the equipment operation.
