Description

Technical Field

[0001] The present invention relates to the technical field of polystyrene plastic recycling, and particularly to a device and method for recycling polystyrene plastic materials for household appliances. Background Art

[0002] Polystyrene plastic is one of the common plastics and is widely used in food containers, packaging materials, disposable items and other fields. However, due to its difficulty in degradation, the recycling of polystyrene plastic is particularly important.

[0003] Common recycling methods are divided into two types: mechanical recycling and chemical recycling. Among them, mechanical recycling is cumbersome, requiring cleaning, crushing and reprocessing, while chemical recycling is simple. There are two specific methods: polymer pyrolysis and dissolution method. Among them, the polymer pyrolysis method requires dissolving polystyrene plastic and injecting a special gas into the polystyrene plastic solution mixture to precipitate polystyrene plastic monomers, which needs to be completed using a gas-liquid mixing kettle. Therefore, the gas-liquid mixing device with the publication number CN113828175B is disclosed. The gist is that an annular collision chamber is provided on the outer peripheral side of the enlarged diameter portion, and a stirring chamber is provided on the downstream side of the enlarged diameter portion. The flow path on the downstream side of the enlarged diameter portion is formed into a collision flow path connected to the collision chamber and used for colliding the gas-liquid with the outer peripheral wall of the collision chamber, a straight-through flow path connected to the stirring chamber and for the gas-liquid passing through the central portion of the enlarged diameter portion to go straight, and an outer annular flow path for the gas-liquid to flow from the collision chamber to the stirring chamber. In the stirring chamber, the gas-liquid from the outer annular flow path and the gas-liquid from the straight-through flow path are stirred.

[0004] When the above-mentioned gas-liquid mixing device and the existing gas-liquid mixing kettle are specifically used, they are completed in the mixing reaction kettle, and then a specific gas is introduced to precipitate polystyrene plastic from the mixed solution. However, when the existing mixing reaction kettle is specifically used, a specific gas or a solution dissolved with a specific gas needs to be introduced into the mixture of the organic solution. Then, it precipitates in the solution. The contact surface between the injected specific gas solution and the organic mixture solution is limited. As the reaction progresses, the concentrations of the two solutions decrease, and the precipitation rate of polystyrene plastic will become slower, affecting the production efficiency of polystyrene plastic.

[0005] Therefore, a new device and method for recycling polystyrene plastic materials for household appliances can be adopted to solve the deficiencies of the prior art. Summary of the Invention

[0020] A method for recycling polystyrene plastic materials for household appliances, which is used for the recycling device for polystyrene plastic materials for household appliances as described above, includes the following steps:

[0021] S1. First, place the prepared mixture in the outer cylinder, and then start the motor. The rotation of the driving end of the motor will drive the outer cylinder to rotate through the transmission group;

[0022] S2. The pump pumps the mixture and the organic solution into the preheating box for preheating, and then introduces it into the first dispersion disc through the first liquid inlet pipe. At the same time, the specific gas solution is introduced into the second dispersion disc through the liquid inlet component;

[0023] S3. The mixture of the organic solution and the specific gas solution is ejected through the atomizing nozzles on the first dispersion disk and the second dispersion disk, so that the mixture of the organic solution and the specific gas solution diffuses, increasing the contact area and the contact opportunity between the mixture of the organic solution and the specific gas solution.

[0024] Compared with the existing technology, the advantages of the present invention are as follows:

[0025] 1. When the present polystyrene plastic material recycling device mixes the mixture with the specific gas solution, by setting the atomizing nozzles, the mixture of the organic solution and the specific gas solution is ejected in an atomized state, increasing the contact area between the mixture of the organic solution and the specific gas solution. Then, the fog is heated by the heating wire to raise the temperature of the fog, improving the reaction rate between the mixture of the organic solution and the specific gas solution, thereby improving the precipitation efficiency of the polystyrene plastic.

[0026] 2. When the present polystyrene plastic material recycling device mixes the mixture with the specific gas solution, by setting two vortex fans with opposite directions, the fog of the mixture of the organic solution and the fog of the specific gas solution generate a head-on collision inside the cover plate, increasing the impact force between the two fogs, thereby accelerating the molecular movement rate. And the unpowered mixing tube is used to mix the two fogs, improving the precipitation efficiency of the polystyrene plastic. And the vibrating vane is used to generate fog turbulence inside the cover plate, improving the mixing efficiency of the two fogs, thereby further improving the precipitation efficiency of the polystyrene plastic.

[0027] 3. When the present polystyrene plastic material recycling device mixes the mixture with the specific gas solution, the fifth pipe is blocked by setting the blocking component, and then the blocking component is opened in cooperation with the opening mechanism, realizing the intermittent opening and closing of the fifth pipe and the unpowered mixing tube, generating different turbulences inside the cover plate, disrupting the distribution of the fog inside the cover plate, increasing the contact opportunity between the two fogs, and thus making the reaction more thorough.

[0028] In summary, the present invention turns the mixture of the organic solution and the specific gas solution into fog with a certain temperature after atomization, increasing the molecular movement rate of the two fogs, improving the reaction efficiency. At the same time, during mixing, unstable turbulences and vibration waves are generated inside the annular baffle, increasing the collision opportunity between the two fogs, making the reaction more thorough, and further improving the reaction efficiency.

Specific embodiments

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] Embodiment 1: Refer to Figures 1 - 7 , a recycling device for household appliance polystyrene plastic materials, including a frame body 1, and further including a motor 2 and a preheating box 9 fixedly installed on the frame body 1;

[0052] An outer cylinder 4 is rotatably mounted on a frame body 1 through a track 6. A cylinder cover 10 is rotatably mounted on the outer cylinder 4. A filter cloth cover 11 is fixedly mounted inside the outer cylinder 4. A second dispersion plate 16 is fixedly mounted inside the outer cylinder 4. A first dispersion plate 15 is fixedly mounted on the cylinder cover 10. The first dispersion plate 15 is communicated with a preheating box 9 through a first liquid inlet pipe 7. One end of the preheating box 9 far from the first liquid inlet pipe 7 is fixedly connected with a pump 5. A liquid inlet assembly matched with the second dispersion plate 16 is mounted on the outer cylinder 4;

[0053] A plurality of atomizing nozzles 42 are fixedly mounted on both the first dispersion plate 15 and the second dispersion plate 16. A mixing assembly is mounted between the first dispersion plate 15 and the second dispersion plate 16. The motor 2 is driven by a transmission group 3 between the outer cylinder 4.

[0054] The pump 5 pumps the mixture of the organic solution into the preheating box 9 for preheating, and then introduces it into the first dispersion plate 15 through the first liquid inlet pipe 7. At the same time, the specific gas solution is introduced into the second dispersion plate 16 from the liquid inlet assembly. The mixture of the organic solution and the specific gas solution is ejected through the atomizing nozzles 42 on the first dispersion plate 15 and the second dispersion plate 16, so that the mixture of the organic solution and the specific gas solution diffuses, increasing the contact area and the contact opportunity between the mixture of the organic solution and the specific gas solution.

[0055] The liquid inlet assembly includes a second annular liquid guide box 13 fixedly mounted outside the outer cylinder 4. The second annular liquid guide box 13 is communicated with the second dispersion plate 16 through a plurality of communicating pipes 14. A first annular liquid guide box 12 is rotatably mounted outside the second annular liquid guide box 13. The first annular liquid guide box 12 is communicated with the second annular liquid guide box 13. The first annular liquid guide box 12 is fixedly connected with the frame body 1. A second liquid inlet pipe 8 is fixedly communicated with the first annular liquid guide box 12.

[0056] Since the outer cylinder 4 will rotate, the second annular liquid guide box 13 fixedly connected with the outer cylinder 4 will also rotate. However, the first annular liquid guide box 12 is rotationally connected with the second annular liquid guide box 13, so the rotation of the second annular liquid guide box 13 will not drive the first annular liquid guide box 12 to rotate, keeping the position of the second liquid inlet pipe 8 constant for inputting the specific gas solution.

[0057] Embodiment 2: The difference between this embodiment and the technical solution of Embodiment 1 lies in: Refer to Figures 1 - 6 、 Figures 8 - 19 , a mixing assembly is mounted between the first dispersion plate 15 and the second dispersion plate 16;

[0058] The mixing assembly includes two conduits 19. One of the two conduits 19 is rotatably connected to the first dispersion disc 15, and the other conduit 19 is fixedly connected to the second dispersion disc 16. A first heat shield 17 and a second heat shield 18 are respectively and fixedly installed on the two conduits 19. The second heat shield 18 is fixedly connected to the second dispersion disc 16, and the first heat shield 17 is rotatably connected to the first dispersion disc 15. Heating wires 20 are fixedly installed between the first heat shield 17 and the second heat shield 18 and the corresponding conduits 19;

[0059] The heating wires 20 are used to heat the atomized mixture (a mixture of an organic solution and a specific gas solution) in the conduits 19, which can increase the uniform molecular speed and thus accelerate the reaction rate.

[0060] The functions of the first heat shield 17 and the second heat shield 18 are to insulate the heat of the heating wires 20, so that the external temperatures of the first heat shield 17 and the second heat shield 18 are relatively low, which is beneficial to the precipitation of polystyrene plastic.

[0061] At one end where the two conduits 19 are close to each other, an annular baffle is fixedly installed at each end. A plurality of cover plates 21 are rotatably installed between the two annular baffles. A first spring coil 22 is fixedly installed between each cover plate 21 and the two annular baffles. At one end where the two conduits 19 are close to each other, a vortex fan 24 is fixedly installed at each end. A turbulence mechanism is installed between the two vortex fans 24.

[0062] The atomized mixture (a mixture of an organic solution and a specific gas solution) will enter the conduits 19, and then the vortex fans 24 are used to make the mixture (a mixture of an organic solution and a specific gas solution) in the conduits 19 rotate to form a swirling flow, which is beneficial to increasing the probability of collision between the mixture (a mixture of an organic solution and a specific gas solution). Since the directions of the two vortex fans 24 are different, the mixture (a mixture of an organic solution and a specific gas solution) will collide with each other.

[0063] The turbulence mechanism includes a first pipe 27 and a second pipe 28. The first pipe 27 is fixedly installed on the vortex fan 24 on the side close to the first dispersion disc 15, and the second pipe 28 is fixedly installed on the vortex fan 24 on the side close to the second dispersion disc 16. A fourth pipe 33 is rotatably installed on the first pipe 27, and a third pipe 32 is rotatably installed on the second pipe 28. A locking mechanism is installed between the second pipe 28 and the third pipe 32;

[0064] On one side where the third pipe 32 and the fourth pipe 33 are close to each other, an annular bracket 35 is fixedly installed at each side. A fifth pipe 34 is fixedly installed between the two annular brackets 35. A plurality of non-powered mixing pipes 25 are fixedly connected to the fifth pipe 34. Two vibration paddles 26 are fixedly installed at the end of each non-powered mixing pipe 25.

[0065] A part of the mixture, which is a mixture of an organic solution and a specific gas solution, passes through between the blades of the fan 24 of the turbofan, while another part of the mixture, which is also a mixture of an organic solution and a specific gas solution, passes through the middle position of the turbofan 24 and enters the corresponding first pipe 27 and second pipe 28. Then, it enters the fifth pipe 34 through the third pipe 32 and the fourth pipe 33, and then is ejected through the unpowered mixing pipe 25 on the fifth pipe 34 and enters between the two annular baffles;

[0066] The unpowered mixing pipe 25 is an existing mixing device with baffles designed in multiple sections of helix inside. The mixture of the organic solution and the specific gas solution will be mixed inside the unpowered mixing pipe 25. Since it is an existing device, no detailed description is given to the unpowered mixing pipe 25.

[0067] When the mixture of the organic solution and the specific gas solution ejected from the unpowered mixing pipe 25 impacts on the vibrating vane 26, the vibrating vane 26 vibrates, causing the mixture of the organic solution and the specific gas solution inside the annular baffle to vibrate and generate turbulence, making the reaction more thorough and also accelerating the reaction rate.

[0068] The locking mechanism includes a plurality of support frames 43 fixedly installed on the second pipe 28. A sliding rod is slidably installed on each support frame 43. A centrifugal ball 30 is fixedly installed at one end of each sliding rod away from the second pipe 28, and a clamping plate 44 cooperating with the third pipe 32 is fixedly installed at one end of each sliding rod close to the second pipe 28. A pressing spring 45 is fixedly installed between each clamping plate 44 and the corresponding support frame 43.

[0069] Sealing components 31 are installed between the third pipe 32, the fourth pipe 33 and the fifth pipe 34.

[0070] During mixing, the rotation speed of the outer cylinder 4 is relatively low, generally 2 - 3 seconds per revolution. When mixing for a certain period of time, the rotation speed of the outer cylinder 4 is increased, and under the action of centrifugal force, the cover plate 21 will automatically open, and the substances adhered to the cover plate 21 will be thrown out.

[0071] Due to the increase in rotation speed, the opening and closing frequency of the sealing component 31 increases. If the sealing component 31 remains open at high rotation speed, the mixture of the organic solution and the specific gas solution will enter the fifth pipe 34 again through the unpowered mixing pipe 25, causing the mixture to flow back. Therefore, at high rotation speed, it is necessary to keep the sealing component 31 closed;

[0072] This is achieved through a locking mechanism. The specific operation steps are as follows: When the rotational speed is relatively high, the centrifugal force acting on the centrifugal ball 30 is greater than the elastic force of the pressing spring 45. At this time, the centrifugal ball 30 will move towards the side away from the third pipe 32, driving the clamping plate 44 to move through the slide rod, causing the clamping plate 44 to separate from the third pipe 32. At this time, the third pipe 32 loses the clamping of the clamping plate 44 and will have a relative displacement with the second pipe 28. At this time, the second pipe 28 rotates without driving the third pipe 32 to rotate, and the blocking component 31 will not be triggered to operate. At this time, the blocking component 31 remains in the closed state. After the rotational speed decreases, under the action of the pressing spring 45, the clamping plate 44 is reset. Under the clamping of the clamping plate 44, the second pipe 28 will drive the third pipe 32 to rotate, thereby triggering the operation of the blocking component 31.

[0073] Blocking components 31 are installed between the third pipe 32, the fourth pipe 33 and the fifth pipe 34; the blocking component 31 includes a plurality of blocking plates 39 rotatably installed on the annular bracket 35. The plurality of blocking plates 39 enclose a seamless disc for blocking the joints between the third pipe 32, the fourth pipe 33 and the fifth pipe 34. A plurality of meshing teeth are fixedly installed on the blocking plates 39;

[0074] An intermittent toothed ring 40 that cooperates with all the meshing teeth is rotatably installed on the annular bracket 35. A rotating shaft 36 is rotatably installed on the annular bracket 35. A first gear 37 that meshes with the intermittent toothed ring 40 is rotatably installed on the rotating shaft 36. A second gear 41 is fixedly installed on the rotating shaft 36. An incomplete toothed ring 38 that meshes with the second gear 41 is fixedly installed on the first pipe 27. A second spring coil is fixedly installed between the rotating shaft 36 and the annular bracket 35 for resetting the rotating shaft 36.

[0075] When the outer cylinder 4 rotates at a low speed, the second pipe 28 will drive the third pipe 32 to rotate. The third pipe 32 drives the fifth pipe 34 to rotate through the annular bracket 35. The rotation of the fifth pipe 34 drives the fourth pipe 33 to rotate through another annular bracket 35;

[0076] As the annular bracket 35 rotates, it drives the rotating shaft 36 to perform a circular motion around the central axes of the first tube 27 and the second tube 28. The incomplete gear ring 38 is fixed on the first tube 27, and the first tube 27 does not rotate, so the incomplete gear ring 38 does not rotate. However, the rotating shaft 36, the first gear 37 and the second gear 41 on the rotating shaft 36 will all perform circular motions along with the rotating shaft 36. When the second gear 41 meshes with the incomplete gear ring 38, the second gear 41 will rotate, thereby driving the rotating shaft 36 to rotate. The rotation of the rotating shaft 36 drives the first gear 37 to rotate, and the rotation of the first gear 37 drives the intermittent gear ring 40 meshing with it to rotate. The rotation of the intermittent gear ring 40 drives the sealing plate 39 equipped with multiple meshing teeth to rotate, thereby realizing the opening of the sealing assembly 31. Due to the action of the incomplete gear ring 38 and the second spring coil, the sealing assembly 31 will be opened and closed intermittently, which can form a turbulent flow, improve the diffusion speed of the mixture of the organic solution and the specific gas solution, and thus improve the mixing reaction efficiency.

[0077] The motor 2 and the outer cylinder 4 are driven by a transmission unit 3. The transmission unit 3 is an existing transmission structure, which is composed of a crawler roller and a transmission track, and has the advantage of reducing the influence of vibration on the transmission, making the outer cylinder 4 rotate more smoothly and stably.

[0078] A liquid outlet ring 46 is rotatably installed on the outer cylinder 4. The bottom of the liquid outlet ring 46 is fixedly communicated with a liquid outlet pipe 47, and the liquid outlet pipe 47 is fixedly connected to the frame body 1.

[0079] The precipitated polystyrene plastic in the reaction will fall onto the filter cloth cover 11 for filtration. The polystyrene plastic will adhere to the filter cloth cover 11, and the liquid after the reaction will be filtered and fall into the outer cylinder 4, and then be introduced into the liquid outlet pipe 47 through the liquid outlet ring 46 on the outer cylinder 4 for discharge.

[0080] The operation steps of this device are as follows:

[0081] First, place the prepared mixture in the outer cylinder 4, and then start the motor 2. The rotation of the driving end of the motor 2 will drive the outer cylinder 4 to rotate through the transmission unit 3;

[0082] The pump 5 pumps the mixture of the organic solution into the preheating box 9 for preheating, and then introduces it into the first dispersion plate 15 through the first liquid inlet pipe 7. At the same time, the specific gas solution is introduced into the second dispersion plate 16 from the liquid inlet assembly;

[0083] The mixture of the organic solution and the specific gas solution are sprayed through the atomizing nozzles 42 on the first dispersion plate 15 and the second dispersion plate 16, so that the mixture of the organic solution and the specific gas solution diffuses, increasing the contact area and contact opportunity between the mixture of the organic solution and the specific gas solution.

[0084] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered by the protection scope of the present invention.
