Description

Technical Field

[0001] This utility model belongs to the field of plastic recycling, specifically relating to a reciprocating plastic washing tank. Background Technology

[0002] Plastic recycling refers to the process of collecting, sorting, and processing waste plastic products to obtain usable plastic materials or products again. This not only reduces plastic waste pollution and conserves resources but also promotes economic cycles. However, recycled waste plastic products usually contain impurities such as mud and sand, requiring cleaning before they can be reused.

[0003] In the prior art, such as the patent document with publication number CN213648268U, a cleaning device for recycling fluoroplastics that facilitates the removal of debris is disclosed. This device cleans the plastic by spraying water through a spray plate and nozzles on a rotating rod. However, the spraying method cannot guarantee that every part of the plastic is cleaned thoroughly, resulting in poor cleaning effect. Furthermore, to improve the cleaning effect, the length of the rotating rod needs to be increased, causing the cleaning device to occupy too much space. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model proposes a reciprocating plastic cleaning tank. By immersing the plastic products in the cleaning solution, it ensures that every part of the plastic products can be cleaned. Furthermore, the serpentine cleaning channel extends the cleaning path while keeping the volume of the cleaning tank constant, thus avoiding excessive length and saving installation space.

[0005] This invention is implemented as follows: A reciprocating plastic cleaning tank for cleaning plastic products includes a cleaning chamber and an impurity collection chamber arranged vertically. The bottom of the cleaning chamber is connected to the impurity collection chamber, and both the cleaning chamber and the impurity collection chamber are filled with cleaning liquid. During cleaning, the plastic products are completely immersed in the cleaning liquid to ensure that every part of the plastic products is cleaned, thus improving the cleaning effect. The cleaning chamber has multiple horizontally arranged rotating shafts, with partitions between them dividing the cleaning chamber into a serpentine reciprocating cleaning channel. Each rotating shaft has a first helical blade on its circumference, and the first helical blades on adjacent rotating shafts rotate in opposite directions, causing the plastic products to move reciprocally along the cleaning channel within the cleaning chamber. The cleaning channel increases the cleaning path of the plastic products several times over, further improving the cleaning effect of the cleaning tank without increasing its volume.

[0006] The rotating shaft is also equipped with a first deflector plate on its side wall. The plastic product of the first deflector plate is inserted into the cleaning liquid. Since the density of the plastic product is less than that of the cleaning liquid, the plastic product will float on the top of the cleaning liquid. The first deflector plate pushes the plastic product downward, causing the plastic product to rise and fall in the cleaning liquid, which further improves the cleaning effect of the cleaning tank.

[0007] Preferably, the impurity collection chamber gradually decreases in size from top to bottom, making its cross-section V-shaped, and an impurity collection trough is formed at the bottom of the chamber. An impurity discharge port is provided on the side of the impurity collection trough. Since impurities on plastic products are usually mud and sand, they will gradually sink to the bottom of the impurity collection chamber under the washing liquid. The gradually decreasing size of the impurity collection chamber from top to bottom concentrates the impurities inside into the impurity collection trough, facilitating subsequent cleaning and improving the convenience of the washing tank.

[0008] Specifically, the impurity collection tank is further equipped with a rotatably connected collection shaft. The collection shaft includes a collection section corresponding to the impurity discharge port. A second spiral blade and a third spiral blade are respectively provided on both sides of the collection section, and the second and third spiral blades rotate in opposite directions. When the collection shaft rotates, the second and third spiral blades move the impurities on both sides of the collection section towards the collection section, thereby concentrating the impurities in the collection tank at the impurity discharge port, further improving the convenience of cleaning impurities.

[0009] Preferably, the distance from the outer edge of the first deflector plate to the axis of the rotating shaft is less than the distance from the outer edge of the first helical blade to the axis of the rotating shaft. Since the plastic product moves up and down under the influence of the first deflector plate, when the distance from the outer edge of the first deflector plate to the axis of the rotating shaft is less than the distance from the outer edge of the first helical blade to the axis of the rotating shaft, it prevents the first deflector plate from pushing the plastic product downwards out of the transmission range of the first helical blade, thus preventing the plastic product from being transported and improving the reliability of the rotating shaft.

[0010] Specifically, the first dial plate is divided into multiple slats by the first spiral blade, and each slat has multiple through holes, with the distribution area of ​​the through holes being greater than or equal to 1 / 2 of the area of ​​the slat. The through holes are used to reduce the force exerted on the cleaning fluid when the first dial plate rotates, thereby reducing fluctuations in the cleaning fluid, preventing the cleaning fluid from stirring up impurities in the impurity collection chamber, and preventing the cleaned plastic products from being contaminated by impurities again.

[0011] Preferably, when the end of the rotating shaft corresponds to the corner of the cleaning channel, the end of the rotating shaft is provided with a second deflector plate, and the distance from the outer edge of the second deflector plate to the axis of the rotating shaft is greater than the distance from the outer edge of the first spiral blade to the axis of the rotating shaft.

[0012] Preferably, the end of the cleaning channel is provided with an inclined surface, which gradually slopes upward along the extension direction of the cleaning channel; the top of the inclined surface is also provided with a discharge port. The inclined surface is used to drain the cleaning liquid on the plastic products. The cleaned plastic products are transported sequentially onto the inclined surface, and subsequent plastic products push the preceding plastic products onto the inclined surface. At the same time, the residual cleaning liquid on the plastic products flows onto the inclined surface and then flows back into the cleaning channel through the inclined surface, reducing the loss of cleaning liquid.

[0013] Preferably, the system further includes a transmission mechanism, which comprises a drive unit and a transmission unit corresponding to the rotating shaft. The drive unit is drively connected to the first or last rotating shaft; adjacent rotating shafts are drively connected to each other via the transmission units. Connecting multiple rotating shafts through the transmission units ensures the synchronicity of their rotation, thereby allowing the plastic product to move at a uniform speed within the cleaning channel. This prevents asynchronous rotation of multiple rotating shafts from causing inconsistent speeds of the plastic product within the cleaning channel, which could lead to material blockage and improves the reliability of the rotating shafts.

[0014] Specifically, the transmission mechanism also includes a protective cover that covers multiple transmission units to prevent mechanical injury from the transmission mechanism during operation, thereby improving the safety of the transmission mechanism.

[0015] Preferably, the top of the cleaning chamber is provided with multiple cover plates, which are arranged side by side along the extension direction of the rotating shaft. The cover plates are used to prevent the cleaning fluid from splashing, reducing the loss of the cleaning fluid; the multiple side-by-side cover plates reduce the size of a single cover plate, making the cover plates easier to install and remove, and improving the convenience of installing and removing the cover plates.

[0016] The beneficial effects of this utility model are:

[0017] This utility model proposes a reciprocating plastic cleaning tank. On the one hand, by immersing the plastic product in the cleaning solution, it ensures that every part of the plastic product is cleaned, and the first baffle makes the plastic product move up and down in the cleaning solution, which improves the cleaning effect. On the other hand, the serpentine reciprocating cleaning channel lengthens the cleaning path while keeping the volume of the cleaning tank unchanged, avoiding the cleaning tank from being too long and saving the installation space required for the cleaning tank.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-6 As shown, a reciprocating plastic cleaning tank includes a cleaning chamber 1 and an impurity collection chamber 2 arranged vertically. The bottom of the cleaning chamber 1 is connected to the impurity collection chamber 2, and both the cleaning chamber 1 and the impurity collection chamber 2 are filled with cleaning liquid. When cleaning, the plastic products are completely immersed in the cleaning liquid to ensure that every part of the plastic products can be cleaned, thereby improving the cleaning effect.

[0028] In this embodiment, the impurity collection chamber 2 gradually decreases in size from top to bottom, making its cross-section V-shaped. An impurity collection trough 21 is formed at the bottom of the impurity collection chamber 2, and an impurity discharge port is provided on the side of the impurity collection trough 21. Since the impurities on plastic products are usually mud and sand, they will gradually sink to the bottom of the impurity collection chamber 2 under the washing liquid. The gradually decreasing size of the impurity collection chamber 2 from top to bottom allows the impurities inside to be concentrated in the impurity collection trough 21, which facilitates the later cleaning of impurities and improves the convenience of the washing tank.

[0029] Specifically, the impurity collection tank 21 is further provided with a rotatably connected collection shaft 22. The collection shaft 22 includes a collection section 221 corresponding to the impurity discharge port. A second spiral blade 222 and a third spiral blade 223 are respectively provided on both sides of the collection section 221, and the second spiral blade 222 and the third spiral blade 223 rotate in opposite directions. When the collection shaft 22 rotates, the second spiral blade 222 and the third spiral blade 223 move the impurities on both sides of the collection section 221 towards the collection section 221, thereby concentrating the impurities in the impurity collection tank 21 at the impurity discharge port, further improving the convenience of cleaning impurities.

[0030] The cleaning chamber 1 is provided with three horizontally arranged rotating shafts 11, and a partition 12 is provided between each rotating shaft 11. The partition 12 divides the cleaning chamber 1 into an S-shaped cleaning channel 13. The rotating shaft 11 is provided with a first spiral blade 111 on its periphery, and the first spiral blades 111 on two adjacent rotating shafts 11 rotate in opposite directions, so that the plastic product moves back and forth in the cleaning chamber 1 along the cleaning channel 13. The cleaning channel 13 makes the cleaning path of the plastic product several times longer than the original, further improving the cleaning effect of the cleaning tank without increasing the volume of the cleaning tank.

[0031] In this embodiment, the top of the cleaning chamber 1 is provided with multiple cover plates 4, which are arranged side by side along the extension direction of the rotating shaft 11. The cover plates 4 are used to prevent the cleaning fluid from splashing, thereby reducing the loss of the cleaning fluid; the multiple side-by-side cover plates 4 reduce the size of a single cover plate 4, making the cover plate 4 easier to install and remove, and improving the convenience of installing and removing the cover plate 4.

[0032] In this embodiment, when the end of the rotating shaft 11 corresponds to the corner of the cleaning channel 13, the end of the rotating shaft 11 is provided with a second deflector 113. The distance from the outer edge of the second deflector 113 to the axis of the rotating shaft 11 is greater than the distance from the outer edge of the first spiral blade 111 to the axis of the rotating shaft 11.

[0033] In this embodiment, the end of the cleaning channel 13 is provided with an inclined surface 131, which gradually slopes upward along the extending direction of the cleaning channel 13; the top of the inclined surface 131 is also provided with a discharge port 132. The inclined surface 131 is used to drain the cleaning liquid on the plastic products. The cleaned plastic products are transported sequentially onto the inclined surface 131, and subsequent plastic products push the previous plastic products onto the inclined surface 131. At the same time, the residual cleaning liquid on the plastic products will flow onto the inclined surface 131 and then flow back into the cleaning channel 13 through the inclined surface 131, reducing the loss of cleaning liquid.

[0034] In this embodiment, a transmission mechanism 3 is also included. The transmission mechanism 3 includes a drive unit 31 and a transmission unit 32 corresponding to the rotating shaft 11. The drive unit 31 is driveably connected to the first or last rotating shaft 11; adjacent rotating shafts 11 are driveably connected to each other through the transmission unit 32. By connecting multiple rotating shafts 11 through the transmission unit 32, the synchronicity of the rotation of multiple rotating shafts 11 is ensured, thereby enabling the plastic product to move at a uniform speed within the cleaning channel 13. This prevents the plastic product from moving at inconsistent speeds within the cleaning channel 13 due to asynchrony among multiple rotating shafts 11, which could lead to material blockage and improve the reliability of the rotating shaft 11.

[0035] In this embodiment, the drive unit 31 is a motor, and the transmission unit 32 is a chain.

[0036] Specifically, the transmission mechanism 3 also includes a protective cover 33, which covers multiple transmission units 32 to prevent mechanical injury from the transmission mechanism 3 during operation and improve the safety of the transmission mechanism 3.

[0037] A first deflector 112 is also provided on the side wall of the rotating shaft 11, extending linearly from the beginning to the end of the rotating shaft 11. The plastic product moves along the cleaning channel 13, and the first deflector 112 pushes the plastic product floating on the cleaning liquid into the cleaning liquid. Because the density of the plastic product is less than that of the cleaning liquid, the plastic product floats on top of the cleaning liquid. The first deflector 112 pushes the plastic product downwards, causing it to rise and fall within the cleaning liquid, further improving the cleaning effect of the cleaning tank.

[0038] In this embodiment, the distance from the outer edge of the first dial plate 112 to the axis of the rotating shaft 11 is less than the distance from the outer edge of the first spiral blade 111 to the axis of the rotating shaft 11. Since the plastic product moves up and down under the influence of the first dial plate 112, when the distance from the outer edge of the first dial plate 112 to the axis of the rotating shaft 11 is less than the distance from the outer edge of the first spiral blade 111 to the axis of the rotating shaft 11, it prevents the first dial plate 112 from pushing the plastic product downwards out of the transmission range of the first spiral blade 111, thus preventing the plastic product from being transported and improving the reliability of the rotating shaft 11.

[0039] Specifically, the first dial plate 112 is divided into multiple dial blades 1121 by the first spiral blade 111. Each dial blade 1121 is provided with multiple through holes 1122, and the area of ​​the through holes 1122 is greater than or equal to 1 / 2 of the area of ​​the first dial plate 112. The through holes 1122 are used to reduce the force exerted on the cleaning fluid when the first dial plate 112 rotates, thereby reducing the fluctuation of the cleaning fluid, preventing the cleaning fluid from stirring up impurities in the impurity collection chamber 2, and preventing the cleaned plastic products from being contaminated by impurities again.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
