[0002] In the chemical fiber industry, a large part of the raw materials are PET flakes. After the whole bottle is crushed by a crusher, it becomes flakes. However, because there are still a lot of residual substances on the bottle, and in addition, it has been exposed to the outside for a long time, there are more impurities on the flakes. Therefore, the flakes must be cleaned first before the subsequent spinning process.

[0003] After retrieval, a patent with the Chinese patent publication number CN207103296U discloses a cleaning device for PET flakes, including a support base, a cleaning cylinder, an upper cylinder cover, and a cylinder rotating motor; one end of the upper cylinder cover is fixedly connected to the support base, the bottom end of the cleaning cylinder is rotatably supported on the support base, the upper end of the cleaning cylinder has an open mouth, and the upper cylinder cover covers the open mouth of the cleaning cylinder; a stirring motor is provided at the center of the upper surface of the upper cylinder cover, the output shaft of the stirring motor is connected to a stirring shaft, a first stirring paddle is provided on the stirring shaft, and the stirring shaft is located inside the cleaning cylinder and coaxial with the cleaning cylinder; a threaded portion is provided on the outer side wall of the cleaning cylinder; the cylinder rotating motor is fixedly arranged on the support base and is provided with a threaded output shaft meshing with the threaded portion; the cleaning cylinder makes a rotational movement around the axis of the cleaning cylinder driven by the threaded output shaft.

[0004] The above patent has the following deficiencies: It uses a stirring form with a vertical axis for cleaning. Since the density of the flakes is small, most of them will float on the cleaning water surface, and the stirring effect of the vertical axis is poor, resulting in a poor cleaning effect. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a PET plastic flake cleaning device with an automatic filtering function.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A PET plastic flake cleaning device with an automatic filtering function includes a base and a columnar container fixed to the top of the base through legs. A cleaning part is arranged inside the columnar container. The cleaning part includes a horizontal axis stirring component and a driving component. The driving component is in transmission cooperation with the horizontal axis stirring component. A circulating water part communicating with the inner cavity of the columnar container is arranged at the bottom of the columnar container. The circulating water part includes a filter type water circulation component and a pH adjustment component fixed to the top of the base. The pH adjustment component is installed on a branch of the filter type water circulation component.

[0008] Preferably: The horizontal axis stirring assembly includes an outer shaft rotatably connected to the inner wall of the cylindrical container and an inner shaft rotatably connected to the inner wall of the outer shaft. Multiple groups of stirring plates are fixed to the outer walls of both the outer shaft and the inner shaft through support rods.

[0009] Further: The driving assembly includes a second bevel gear fixedly installed on the outer wall of the outer shaft, a third bevel gear fixedly installed on the outer wall of the inner shaft, and a first bevel gear meshing with the opposite sides of the second bevel gear and the third bevel gear. A motor is fixedly installed on the outer wall of the cylindrical container, and the output shaft of the motor is key-connected to the inner wall of the first bevel gear.

[0010] Based on the foregoing solution: A feeding port is fixedly installed on the outer wall of the top of the cylindrical container, and a top cover is rotatably connected to the outer wall of the top of the feeding port. A discharge port is fixedly installed on the bottom side wall of the cylindrical container, and a valve is installed on the outer wall of the discharge port.

[0011] A better solution in the foregoing solution is: The filter-type water circulation assembly includes a drain port fixedly installed at the bottom of the cylindrical container and a nozzle clamped to the inner wall of the top cover. The bottom of the drain port is connected to a filter box, the water outlet of the filter box is connected to a first water pump through a connecting pipe, the top of the first water pump is connected to a three-way valve, and the three-way valve is connected to the water inlet of the nozzle through a hose.

[0012] As a further solution of the present invention: A metal grille is fixedly installed on the inner wall of the cylindrical container at the drain port.

[0013] Meanwhile, the pH adjustment assembly includes a pH adjustment box containing a cleaning solution and a second water pump. The water inlet and the water outlet of the second water pump are respectively connected to the pH adjustment box and the three-way valve.

[0014] As a preferred solution of the present invention: The pH adjustment assembly further includes a pH detector. A boss is fixedly installed on the outer wall of the top of the connecting pipe, and the probe of the pH detector is threadedly connected to the inside of the boss.

[0015] Meanwhile, the support rod includes support blocks slidably connected to each other through a sliding rod. One of the support blocks is fixedly installed on the outer walls of the outer shaft and the inner shaft, and the other support block is fixedly welded to the stirring plate.

[0016] As a better solution of the present invention: Annular grooves are provided on both inner walls of the cylindrical container, and a centripetal depression is provided at the bottom of the annular groove. The outer wall of the stirring plate is rotatably connected to a roller through a rotating shaft, and the roller is in rolling fit with the inner wall of the annular groove.

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

[0018] 1. In the present invention, by arranging a horizontally disposed outer shaft and an inner shaft, and connecting the stirring plates to the outer wall through support rods, a longitudinal total force can be exerted on the water containing PET flakes during rotation, so that the PET flakes can be reliably immersed in the water and cleaned by relative movement, thereby improving the cleaning effect.

[0019] 2. In the present invention, by arranging an outer shaft and an inner shaft that are rotatably connected to each other, and driving them through the meshing of bevel gear one, bevel gear two and bevel gear three, the outer shaft and the inner shaft rotate in opposite directions, thereby increasing the degree of chaos inside the columnar container by the stirring plates, and further improving the cleaning effect.

[0020] 3. In the present invention, by arranging a filter box, a water pump one and a nozzle, during the stirring and cleaning process, the sewage for cleaning can be pumped out from the bottom by the water pump one, filtered through the filter box, and then sprayed towards the inside of the columnar container at high pressure through the nozzle at the top. On the one hand, it can keep the cleaning water source in a relatively clean state all the time, and on the other hand, the high-pressure backflow can also play a certain role in flushing the PET flakes, improving the cleaning effect.

[0021] 4. In the present invention, by arranging a water pump two and a pH adjustment box, while filtering the water circulation, it can continuously supplement the cleaning liquid into the circulating water injection, thereby preventing the unreliable cleaning caused by the consumption of the cleaning liquid, and further improving the cleaning effect.

[0022] 5. In the present invention, when the stirring plates rotate with the outer shaft and the inner shaft, the rollers roll and cooperate in the annular groove. When running to the bottom, the rollers are restricted by the annular groove, causing them to move closer to the axis, that is, reducing the stirring area, so as to effectively prevent the large-density impurities that have settled at the bottom of the entire columnar container from being stirred into other places again, and further improving the cleaning effect.

For those of ordinary skill in the art, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0035] Embodiment 1:

[0036] A PET plastic bottle chip cleaning device with an automatic filtering function, as Figures 1-7 shown, includes a base 1 and a cylindrical container 4 fixed to the top of the base 1 through legs 3. A cleaning part 5 is arranged inside the cylindrical container 4. The cleaning part 5 includes a horizontal axis stirring component and a driving component. The driving component is in transmission cooperation with the horizontal axis stirring component. A circulating water part 2 communicated with its inner cavity is arranged at the bottom of the cylindrical container 4. The circulating water part 2 includes a filtering type water circulation component and a pH adjustment component fixed to the top of the base 1. The pH adjustment component is installed on a branch of the filtering type water circulation component.

[0037] To solve the problem of stirring effect; as Figure 2 shown, the horizontal axis stirring component includes an outer shaft 9 rotatably connected to the inner wall of the cylindrical container 4 and an inner shaft 12 rotatably connected to the inner wall of the outer shaft 9. A plurality of stirring plates 11 are fixed to the outer walls of the outer shaft 9 and the inner shaft 12 through support rods 10. In this device, by arranging the horizontally arranged outer shaft 9 and inner shaft 12, and connecting the stirring plates 11 through the support rods 10 on their outer walls, a longitudinal total force can be exerted on the water containing PET bottle chips during rotation, so that the PET bottle chips can be reliably immersed in the water and relatively move for cleaning, thereby improving the cleaning effect.

[0038] To solve the transmission problem; as Figure 3 shown, the driving component includes a bevel gear two 17 welded to the outer wall of the outer shaft 9, a bevel gear three 18 welded to the outer wall of the inner shaft 12, and a bevel gear one 16 meshing with the opposite sides of the bevel gear two 17 and the bevel gear three 18. The outer wall of the cylindrical container 4 is fixed with a motor 15 through bolts. The output shaft of the motor 15 is connected to the inner wall of the bevel gear one 16 through a key; by arranging the rotatably connected outer shaft 9 and inner shaft 12, which are driven by the meshing of the bevel gear one 16, the bevel gear two 17 and the bevel gear three 18, the rotation directions of the outer shaft 9 and the inner shaft 12 are opposite, thereby increasing the degree of chaos inside the cylindrical container 4 stirred by the stirring plates 11 and further improving the cleaning effect.

[0039] To solve the problem of feeding and discharging; as Figure 1 、 2As shown, a feeding port 8 is welded to the outer wall of the top of the cylindrical container 4, and a top cover 6 is rotatably connected to the outer wall of the top of the feeding port 8. A discharge port 34 is welded to the bottom side wall of the cylindrical container 4, and a valve 33 is installed on the outer wall of the discharge port 34. Materials can be fed through the feeding port 8, and after cleaning, the bottle flakes can be discharged by opening the valve 33.

[0040] When this embodiment is in use, materials can be fed through the feeding port 8, and clean water is injected. Subsequently, the first bevel gear 16 is started, which drives the outer shaft 9 and the inner shaft 12 to rotate respectively through the second bevel gear 17 and the third bevel gear 18, so as to drive the stirring plate 11 to rotate through the support rod 10, and longitudinally stir and clean the bottle flakes and water in the cylindrical container 4.

[0041] Embodiment 2:

[0042] A PET plastic bottle flake cleaning device with an automatic filtering function, as Figures 1-7 shown. To solve the water circulation problem, the following improvements are made on the basis of Embodiment 1: The filtering water circulation component includes a drain port 14 welded to the bottom of the cylindrical container 4 and a nozzle 7 clamped to the inner wall of the top cover 6. The bottom of the drain port 14 is connected to a filter box 19. The water outlet of the filter box 19 is connected to a water pump 23 through a connecting pipe 20. The top of the water pump 23 is connected to a three-way valve 26, and the three-way valve 26 is connected to the water inlet of the nozzle 7 through a hose. By setting the filter box 19, the water pump 23 and the nozzle 7, during the stirring and cleaning process, the cleaning sewage can be pumped out from the bottom by the water pump 23, filtered by the filter box 19, and then rushed into the interior of the cylindrical container 4 at high pressure through the nozzle 7 at the top. On the one hand, it can keep the cleaning water source in a relatively clean state all the time. On the other hand, the high-pressure backflow can also play a certain role in flushing the PET bottle flakes, improving the cleaning effect.

[0043] To solve the reliable cleaning problem, as Figure 2 shown, a metal grille 13 is welded to the inner wall of the cylindrical container 4 at the drain port 14. The metal grille 13 can block the PET bottle flakes and prevent them from flowing with the water during water circulation.

[0044] To further solve the cleaning effect problem, as Figure 4 shown, the pH adjustment component includes a pH adjustment box 25 containing a cleaning solution and a water pump 24. The water inlet and the water outlet of the water pump 24 are respectively connected to the pH adjustment box 25 and the three-way valve 26. In this embodiment, the type of the cleaning solution is not limited. For cost and degreasing considerations, preferably: the cleaning solution is a weak basic cleaning solution, and more preferably: the cleaning solution is baking soda. By setting the water pump 24 and the pH adjustment box 25, while the water is circulating and filtering, it can continuously supplement the cleaning solution into the circulating injected water, thereby preventing unreliable cleaning caused by the consumption of the cleaning solution, and further improving the cleaning effect.

[0045] To solve the induction problem, such as Figure 4 As shown, the pH adjustment component further includes a pH detector 21. A boss 22 is welded to the outer wall of the top of the connecting pipe 20, and the probe of the pH detector 21 is threadedly connected to the inside of the boss 22. By setting the pH detector 21, it can detect the pH of the upstream water for adding medicine during the water circulation process, so as to judge the consumption of the cleaning liquid based on the pH value.

[0046] In this embodiment: When the first water pump 23 is started, it can pump out the water source that has been contaminated by cleaning from the bottom. After being filtered by the filter box 19, the relatively clean water is then sprayed from the nozzle 7 at the top into the columnar container 4 under high pressure. The metal grid 13 can block the PET bottle flakes to prevent them from flowing with the water during the water circulation. In addition, the pH detector 21 can detect the pH of the upstream water for adding medicine during the water circulation process. When the pH value decreases to the threshold value, the second water pump 24 is started to draw the cleaning liquid from the pH adjustment box 25 for supplementation.

[0047] Embodiment 3:

[0048] A PET plastic bottle flake cleaning device with an automatic filtering function, as Figures 1-7 shown, to solve the problem of impurity backflow; the following improvements are made in this embodiment on the basis of Embodiments 1 and 2: The support rod 10 includes support blocks 27 that are slidably connected to each other through a slide rod 28. One of the support blocks 27 is welded to the outer walls of the outer shaft 9 and the inner shaft 12, and the other support block 27 is fixedly welded to the stirring plate 11. Annular grooves 29 are provided on both inner walls of the columnar container 4, and a centripetal depression 30 is provided at the bottom of the annular groove 29. A roller 31 is rotatably connected to the outer wall of the stirring plate 11 through a rotating shaft 32, and the roller 31 is in rolling fit with the inner wall of the annular groove 29.

[0049] In this embodiment: When the stirring plate 11 rotates with the outer shaft 9 and the inner shaft 12, the roller 31 is in rolling fit within the annular groove 29. When it rotates to the bottom, the roller 31 is restricted by the annular groove 29, causing it to move closer to the axis, that is, reducing the stirring area. Thus, it can effectively prevent the large-density impurities that have settled at the bottom of the entire columnar container 4 from being stirred into other places again, thereby further improving the cleaning effect.

[0050] The above is only a preferred specific embodiment 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 of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
