Description

Technical Field

[0001] The present application relates to the field of plastic recycling technology, and in particular to a disposable plastic waste treatment device. Background Art

[0002] Single-use plastics are products designed to be discarded after a single use. These items are widespread in our daily lives, but they also cause serious environmental pollution. If not properly recycled, they can pollute both soil and water. Plastic waste can alter the structure of the soil, affecting its air permeability, water permeability, and fertility. Once plastic products enter water bodies, they can affect aquatic life and may even lead to eutrophication. If they enter the human body through ecological recycling, microplastics can lodge in the gastrointestinal tract, irritating the gastrointestinal mucosa and causing inflammation, ulcers, and other lesions.

[0003] The existing plastic recycling method mainly recycles waste plastic through plastic crushers. The electric motor drives two reamers to rotate at high speed. The high-speed rotation of the two reamers forms a relative motion, and the gap formed between them is used to create an incision for plastic crushing and shearing, thereby breaking up large pieces of plastic. These broken plastics are then cleaned and melted to make new plastic products. However, common disposable plastic products have different degrees of softness and hardness, and the sizes of the pieces crushed when the reamers are first broken are also different. In addition, some products are light in weight and difficult to be rolled back to the reamers, resulting in the continuous accumulation of such larger fragments, causing blockage of the screen, thereby affecting the discharge. Summary of the Invention

[0004] The present application proposes a disposable plastic waste treatment device, which has the advantage of screening and reselecting large plastic fragments, and is used to solve the problem of continuous accumulation of large fragments and resulting in blockage of the screen.

The above structure can screen, reselect and re-crush large fragments during operation.

[0009] Preferably, the transport assembly includes two fixed plates, both of which are fixedly installed on the top of the sewage tray, two round shafts are movably clamped on the inner sides of the two fixed plates, and tracks are sleeved on the outer edges of the two round shafts. A plurality of round holes are opened through the surface of the tracks, and top connecting strips are movably installed on the inner sides of the two round shafts, and the inner sides of the two top connecting strips are elastically connected to the first spring, and a collection box is fixedly installed on the left side of the tracks.

[0010] Preferably, both ends of the two circular shafts can rotate in the clamping groove on the inner side of the fixed plate, and the two first springs are placed crosswise in an X shape. The above structure can realize a curved pit during operation, thereby improving the contact between plastic fragments and clean water.

[0011] Preferably, the drying assembly includes two groups of fixing rods, the two groups of fixing rods are fixedly installed on the top of the two fixing plates, and the tail ends of the two groups of fixing rods are fixedly connected to the fan group.

[0012] Preferably, the cleaning assembly includes two fixed blocks, both of which are fixedly mounted on the top of the fixed plate, and two grooves are provided on the top of the two fixed blocks, and a plurality of nozzles are fixedly connected to the inner sides of the two fixed blocks, and a connecting pipe is fixedly connected to the right side of the two fixed blocks, and the other ends of the two connecting pipes are fixedly connected to a water storage tank, and the water storage tank is fixedly mounted on the right side of the sewage pan. The above structure can flush and clean plastic fragments during operation.

[0013] Preferably, the two groups of connecting blocks are fixedly installed in the two groups of grooves, and the two groups of bent rods are fixedly connected to the tops of the fixing blocks.

[0014] Preferably, the crushing assembly includes a top shell, which is fixedly mounted on the top of two fixed blocks.

The two crushing mechanisms are installed in an axially symmetrical manner.

[0015] Preferably, the crushing mechanism includes a round rod, which is installed through the middle of the two vertical blocks.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention is equipped with a screening and reselection component. Plastic pieces that are too large will move to the surroundings of the second perforated plate under the influence of shaking force. When the accumulated plastic pieces come into contact with the electric impeller, the electric impeller rotates counterclockwise and lifts these plastic pieces upward. After being guided by the top shell, they will be recaptured by the side of the reamer and crushed for the second time, thereby ensuring that disposable plastics of different hardness can be crushed into similar sizes. This solves the problem that common disposable plastic products have different hardness levels, resulting in different sizes after the first crushing and difficulty in being rolled back to the reamer, which leads to the continuous accumulation of large fragments and the clogging of the screen.

[0019] 2. The present invention is equipped with a newly designed transport component. Some sewage will leak out of the circular hole, but the gravity of the top plastic sheet of the track and the weight of the remaining water will drive the top surface of the track to bend downward for a distance, forming a depression. The depression can achieve complete contact between the water and the plastic fragments, thereby improving the cleaning effect. The two top connecting bars will provide supporting force under the abutment of the cross X-shaped first spring. When the water is discharged and the plastic fragments are transported away, the track is pushed back to the top plane by the X-shaped first spring. This design can improve the cleaning effect of plastic fragments.

[0020] 3. The present invention is equipped with a movable crushing assembly to start two symmetrically installed crushing mechanisms. The two first motors rotate relative to each other, driving the two reamers to rotate relative to each other, thereby performing dual-axis crushing on the disposable plastics entering there. Increasing the stroke of the left and right hydraulic rods can also push the two reamers closer, thereby adjusting the size of the plastic crushing. When the stroke of the left and right hydraulic rods is reduced, the diameter of the plastic crushing can be increased, thereby achieving flexible adjustment of different crushing sizes.

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] See also Figure 1-8 The disposable plastic waste treatment device of this embodiment includes a sewage tray 1, a transport component 2 is fixedly installed on the top of the sewage tray 1, and a linkage processing and cleaning mechanism, which includes a drying component 3, the drying component 3 is fixedly installed on the top of the transport component 2, a cleaning component 4 is fixedly installed on the right side of the drying component 3, and a crushing component 5 is fixedly installed on the top of the cleaning component 4;

[0034] The screening and reselection component 6 includes a first perforated plate 61, a group of connecting blocks 62 are fixedly connected to the left and right sides of the first perforated plate 61, four bent rods 63 are fixedly installed on the top of the first perforated plate 61, the other ends of the four bent rods 63 are fixedly connected to the vibration motor 64, and the bottoms of the four vibration motors 64 are fixedly connected to the second perforated plate 65, two groups of L-shaped rods 66 are fixedly installed on the top of the second perforated plate 65, and two second springs 67 are fixedly installed on the outer edges of the two groups of L-shaped rods 66, and the other ends of the two groups of second springs 67 are elastically connected to the electric impeller 68; the openings of the first perforated plate 61 and the second perforated plate 65 are both square and circular, and the two perforated plates are installed in an upper and lower staggered manner and do not contact each other. The output shaft of the electric impeller 68 is bidirectional and has convex teeth, and a tooth groove is opened in the long end of the L-shaped rod 66, and the bidirectional output shaft is movably installed in the tooth groove;

[0035] Oversized plastic pieces will move toward the periphery of the second punch plate 65 under the influence of the shaking force. When the accumulated plastic pieces contact the electric impeller 68, the electric impeller 68 rotates counterclockwise, lifting the plastic pieces upward. After being guided by the top shell 51, they will be recaptured by the side of the reamer 56 and crushed again, thereby ensuring that disposable plastics of different hardness and softness can be crushed into similar sizes. When the second punch plate 65 vibrates, the electric impeller 68 will move laterally on the L-shaped rod 66, and the second springs 67 on both sides will be elastically deformed and then restored under the force, thereby playing a shock-absorbing role.

[0036] The transport assembly 2 includes two fixed plates 21, both of which are fixedly mounted on the top of the sewage tray 1. Two circular shafts 22 are movably connected to the inner sides of the two fixed plates 21. The outer edges of the two circular shafts 22 are sleeved with tracks 23. The surface of the tracks 23 is penetrated by a plurality of circular holes 24. Top connecting strips 25 are movably mounted on the inner sides of the two circular shafts 22. The inner sides of the two top connecting strips 25 are elastically connected to first springs 26. A collection box 27 is fixedly mounted on the left side of the tracks 23. Both ends of the two circular shafts 22 can rotate in the clamping grooves on the inner sides of the fixed plates 21. The two first springs 26 are arranged crosswise in an X shape.

[0037] The circular shaft 22 is pre-connected with a drive assembly. The clockwise rotation of the circular shaft 22 drives the crawler 23 to rotate clockwise, and the plastic fragments move toward the position of the collection box 27. During the movement, the water storage tank 45 provides a pressurized water source, which is sprayed out from the nozzle 43 through the connecting pipe 44 to clean the plastic pieces. When spraying water, some sewage will leak out of the circular hole 24, but the gravity of the top plastic piece of the crawler 23 and the weight of the remaining water will drive the top surface of the crawler 23 to bend downward for a distance to form a pit. The pit can achieve complete contact between the water and the plastic fragments, thereby improving the cleaning effect. The two top connecting bars 25 will provide supporting force under the abutment of the cross X-shaped first spring 26. When the water is discharged and the plastic fragments are transported away, the crawler 23 is pushed by the X-shaped first spring 26 to return to the top plane.

[0038] The drying assembly 3 includes two sets of fixed rods 31, both of which are fixedly mounted on the top of the two fixed plates 21, and the tail ends of the two sets of fixed rods 31 are fixedly connected to the fan group 32;

[0040] The cleaning assembly 4 includes two fixed blocks 41, both of which are fixedly mounted on the top of the fixed plate 21. Two grooves 42 are provided on the top of the two fixed blocks 41. Multiple nozzles 43 are fixedly connected to the inner sides of the two fixed blocks 41. A connecting pipe 44 is fixedly connected to the right side of the two fixed blocks 41. The other ends of the two connecting pipes 44 are fixedly connected to a water storage tank 45, which is fixedly mounted on the right side of the sewage tray 1; two sets of connecting blocks 62 are fixedly mounted in the two sets of grooves 42, and two sets of bent rods 63 are fixedly connected to the top of the fixed blocks 41;

[0041] The water tank 45 provides pressurized water, which is sprayed through the connecting pipe 44 and out of the nozzle 43 to clean the plastic sheet;

[0042] The crushing assembly 5 includes a top shell 51, which is fixedly mounted on the top of the two fixed blocks 41. Two groups of vertical blocks 52 are fixedly mounted on the top of the top shell 51. Two crushing mechanisms are fixedly mounted in the middle of the two groups of vertical blocks 52, and the two crushing mechanisms are mounted in an axially symmetrical manner. The crushing mechanism includes a round rod 53, which is installed through the middle of the two vertical blocks 52. Two hydraulic rods 54 are fixedly connected to the inner sides of the round rods 53. The telescopic end of the left hydraulic rod 54 is fixedly connected to a first motor 55, and the output shaft end of the first motor 55 is fixedly connected to a reamer 56. The right end of the reamer 56 is movably hinged to the telescopic end of the other hydraulic rod 54. The reamer 56 is a rotating staggered group of multiple rotating blades.

[0043] Start the two symmetrically installed crushing mechanisms, the two first motors 55 rotate relative to each other, driving the two reamers 56 to rotate relative to each other, and perform dual-axis crushing on the disposable plastics entering here. Increasing the stroke of the left and right hydraulic rods 54 can also push the two reamers 56 closer, thereby adjusting the size of the plastic crushing. When the stroke of the left and right hydraulic rods 54 is reduced, the diameter of the plastic crushing can be increased.

[0044] Working principle:

[0045] When using the present invention, first, the disposable plastics to be crushed are continuously and evenly put into the top shell 51, and the two symmetrically installed crushing mechanisms are started. The two first motors 55 rotate relative to each other, driving the two reamers 56 to rotate relative to each other, and the disposable plastics entering here are subjected to dual-axis crushing. Increasing the stroke of the left and right hydraulic rods 54 can also push the two reamers 56 closer, thereby adjusting the size of the crushed plastics. When the stroke of the left and right hydraulic rods 54 is reduced, the diameter of the crushed plastics can be increased.

[0046] The plastic that has been crushed for the first time will be transported to the screening and selection assembly 6 under the action of gravity and the movement of the two reamers 56. At this time, multiple vibration motors 64 are started, driving the second punched plate 65 to vibrate horizontally. The crushed plastic will shake on the top of the second punched plate 65. Plastic pieces of appropriate size will be shaken and discharged in the square and circular holes staggered between the second punched plate 65 and the first punched plate 61. Plastic pieces that are too large will move around the second punched plate 65 under the influence of the shaking force. When the accumulated plastic pieces come into contact with the electric impeller 68, the electric impeller 68 rotates counterclockwise and lifts these plastic pieces upward. After being guided by the top shell 51, they will be recaptured by the side of the reamers 56 for secondary crushing, thereby ensuring that disposable plastics of different hardness and softness are broken into pieces of similar size. When the second punched plate 65 vibrates, the electric impeller 68 will move horizontally on the L-shaped rod 66, and the second springs 67 on both sides will be elastically deformed and then restored under the force, thereby playing a shock-absorbing role.

[0047] The crushed plastic pieces will fall from the screening and recycling assembly 6 and reach the top of the crawler 23. The circular shaft 22 is pre-connected with a driving assembly. The clockwise rotation of the circular shaft 22 can drive the crawler 23 to rotate clockwise, and the plastic fragments move to the position of the collection box 27. During the movement, the water storage tank 45 will provide pressurized water, which will pass through the connecting pipe 44 and be sprayed out from the nozzle 43 to clean the plastic pieces. When spraying water, some sewage will leak out of the circular hole 24, but the gravity of the plastic pieces on the top of the crawler 23 and the weight of the remaining water will drive the top surface of the crawler 23 to bend downward for a distance to form a pit. The pit can achieve complete contact between the water and the plastic fragments, thereby improving the cleaning effect. The two top connecting bars 25 will provide supporting force under the abutment of the cross X-shaped first spring 26. When the water is discharged and the plastic fragments are transported away, the crawler 23 is pushed by the X-shaped first spring 26 to return to the top plane, and the cleaned sewage will enter the sewage tray 1 for collection;

[0048] The cleaned plastic fragments are transported to the fan group 32, which rotates to dry them. After drying, the plastic fragments are placed in the collection box 27 and collected.
