Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning devices, specifically relating to a plastic particle cleaning device. Background Technology

[0002] Today, plastic is a material that is difficult to degrade naturally. In landfills, plastic waste occupies a significant amount of space. Without recycling, plastic waste will continue to accumulate, exacerbating the scarcity of land resources.

[0003] When recycling plastics, they need to be crushed to facilitate subsequent processing. The crushed plastic particles are then cleaned through a cleaning structure.

[0004] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0005] The existing structure is cleaned manually, which requires manual handling and is therefore inefficient. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a plastic particle cleaning device. By optimizing the cleaning device, the problem of requiring manual cleaning is solved, thereby improving cleaning efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A plastic granule washing device includes a washing tank with a first electric valve at the top and a drain outlet at the bottom, and a cleaning cotton lining the inner wall of the washing tank. A stirring structure includes stirring blades, a rotating rod, and a rotating motor. The stirring blades are spaced apart along the length of the rotating rod. One end of each stirring blade and the rotating rod is located inside the washing tank, and the other end of the rotating rod passes through the bottom of the washing tank and connects to the output end of the rotating motor. The surface of the stirring blades is covered with cleaning cotton. Two support frames are respectively located on both sides of the washing tank, with a clamp between the two support frames. The clamp is fixedly connected to the outer wall of the washing tank. A tilting motor is mounted on each support frame, and the output end of the tilting motor is connected to the end of the clamp. A conveying pipe is located above the washing tank, directly facing the first electric valve. A drain outlet is connected to a drain pipe, and a second electric valve is located between the drain outlet and the drain pipe. A collection pipe is located below the washing tank, so that when the washing tank is tilted, the collection pipe faces the first electric valve.

[0009] In some possible implementations, a third electric valve is provided at one end of the delivery pipe facing the first electric valve of the cleaning tank, and the other end of the delivery pipe is connected to a plastic particle delivery pipe, a cleaning liquid delivery pipe, and a water pipe.

[0010] In some possible implementations, a controller is also included, wherein the rotary motor, the tilting motor, the second electric valve, and the third electric valve are all connected to the controller, which is a PLC controller or an embedded controller.

[0011] In some possible implementations, the stirring blades are tilted on the rotating rod, and the tilt angles of two adjacent stirring blades may be the same or different.

[0012] In some possible implementations, the outer diameter of the conveying pipe is smaller than the outer diameter of the first electric valve of the cleaning tank, and the cleaning tank is provided with an inverted conical collection hopper that cooperates with the conveying pipe.

[0013] One of the above technical solutions has the following beneficial effects: +

[0014] This invention optimizes the cleaning device. Through a first electric valve at the top of the cleaning tank, plastic granules, cleaning solution, and water are added to the tank. A rotating motor drives the stirring blades to rotate. Combined with the cleaning cotton on the stirring blades and the inner wall of the cleaning tank, this increases the contact area between the plastic granules and the cleaning cotton. This increased cleaning area and friction between the plastic granules and the stirring blades helps to thoroughly clean the plastic granules. After cleaning, wastewater is discharged through the drain outlet and drain pipe at the bottom of the cleaning tank. Finally, a flipping motor rotates the cleaning tank 180° within the clamp, aligning it with the collection pipe below. The cleaned plastic granules, under gravity, are transported through the collection pipe to a collection box, eliminating the need for manual handling of the plastic granules and improving cleaning efficiency.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings, but this is not intended to limit the present invention.

[0033] Example 1

[0034] The existing structure is cleaned manually, which requires manual handling, making this cleaning method inefficient.

[0035] like Figures 1-2 As shown, the plastic granule washing device of this utility model includes a washing tank 1, with a first electric valve 11 and a drain outlet 12 respectively installed at the top and bottom of the washing tank 1, and cleaning cotton provided on the inner wall of the washing tank 1; a stirring structure 2, including stirring blades 21, a rotating rod 22 and a rotating motor 23, with the stirring blades 21 spaced apart along the length of the rotating rod 22, one end of the stirring blades 21 and the rotating rod 22 located inside the washing tank 1, and the other end of the rotating rod 22 passing through the bottom of the washing tank 1 and connected to the output end of the rotating motor 23, and cleaning cotton provided on the surface of the stirring blades 21; and two support frames 3, respectively installed on the bottom of the washing tank 1. On both sides of the cleaning tub 1, a clamp 4 is provided between two support frames 3. The clamp 4 is fixedly connected to the outer wall of the cleaning tub 1. A flipping motor 5 is installed on the support frame 3. The output end of the flipping motor 5 is connected to the end of the clamp 4. A conveying pipe 6 is provided above the cleaning tub 1. The conveying pipe 6 is directly opposite the first electric valve 11 of the cleaning tub 1. A drain pipe 7 is connected to the drain outlet 12 of the cleaning tub 1. A second electric valve 8 is provided between the drain outlet 12 and the drain pipe 7. A collection pipe 9 is provided below the cleaning tub 1. When the cleaning tub 1 is flipped, the collection pipe 9 is directly opposite the first electric valve 11 of the cleaning tub 1. This invention optimizes the cleaning device. Through the first electric valve at the top of the cleaning tank 1, plastic particles to be cleaned, cleaning fluid, and water can be added to the tank. Then, the rotating motor 23 drives the stirring blade 21 to rotate. Combined with the cleaning cotton on the stirring blade 21 and the cleaning cotton on the inner wall of the cleaning tank 1, the contact area between the plastic particles and the cleaning cotton is increased. This increases the cleaning area and friction between the plastic particles and the stirring blade 21, facilitating thorough cleaning of the plastic particles. After cleaning, wastewater is discharged through the drain outlet 12 and drain pipe 7 at the bottom of the cleaning tank 1. Finally, the flipping motor 5 rotates the cleaning tank 1 in the clamp 4 by 180°, aligning it with the collection pipe 9 below the cleaning tank 1. The cleaned plastic particles are then transported to the collection box through the collection pipe 9 under gravity, eliminating the need for manual handling of the plastic particles and improving the cleaning efficiency.

[0036] It should be noted that: plastic granules, cleaning solution, and water are conveyed into the cleaning tank 1 through the upper conveying pipe 6. The cleaning cotton is preferably a cleaning sponge, whose rough surface increases the friction between the cleaning sponge and the plastic granules, thus improving the cleaning effect of the plastic granules. The first electric valve 11 is closed during the stirring and turning process to prevent leakage. The second electric valve 8 of the drain outlet 12 is closed before and during cleaning to prevent leakage of cleaning solution and water. At the same time, a filter screen is designed between the drain outlet 12 and the drain pipe 7. The pore size of the filter screen is smaller than the outer diameter of the plastic granules to prevent the plastic granules from being discharged from the drain outlet 12. In addition, the length of the drain pipe 7 is designed to accommodate the change in height after the cleaning tank 1 is turned, so as to avoid the drain pipe 7 pulling on the cleaning tank 1 and affecting the turning effect of the cleaning tank 1. The clamp 4 is divided into two symmetrically arranged parts, which are designed to surround the cleaning tank 1 and are connected to the cleaning tank 1 by screws. The clamp 4 has extensions at both ends to facilitate the connection of the clamp 4 to the output end of the turning motor 5. The flip motor 5 and the rotary motor 23 are preferably commercially available servo motors or stepper motors. The flip angle of the cleaning tub 1 is preferably 180°, so that the cleaned plastic particles fall directly into the collection pipe 9 under the action of gravity, which helps to improve the automation level of the cleaning device. The conveying pipe 6 and the collection pipe 9 are fixed in the same way as the cleaning tub 1, by means of clamps. The two ends of the clamps are respectively fixedly connected to the support frame 3, ensuring that the conveying pipe 6, the collection pipe 9 and the first electric valve 11 of the cleaning tub 1 are in the same direction.

[0037] In the plastic granule cleaning device according to this utility model, a third electric valve 10 is provided at one end of the conveying pipe 6 facing the first electric valve 11 of the cleaning tank 1, and the other end of the conveying pipe 6 is connected to a plastic granule conveying pipe, a cleaning liquid conveying pipe, and a water pipe. Specifically, after the third electric valve 10 is opened, the plastic granules, cleaning liquid, and water in the conveying pipe 6 can be added into the cleaning tank 1. The conveying pipe is divided into a plastic granule conveying pipe, a cleaning liquid conveying pipe, and a water pipe, which facilitates the control of the conveying volume of plastic granules, cleaning liquid, and water. In some embodiments, the plastic granules, cleaning liquid, and water can enter from the same pipe, which is not limited here.

[0038] In the plastic particle washing device according to the present invention, the outer diameter of the conveying pipe 6 is smaller than the outer diameter of the first electric valve 11 of the washing tank 1. The washing tank 1 is provided with an inverted conical collecting hopper that cooperates with the conveying pipe 6 to prevent plastic particles from being discharged from the gap between the first electric valve 11 of the washing tank 1 and the conveying pipe 6, and to ensure that the plastic particles are accurately put into the washing tank 1.

[0039] The working principle of this utility model is as follows:

[0040] This invention optimizes the cleaning device. Through the first electric valve at the top of the cleaning tank 1, plastic particles to be cleaned, cleaning fluid, and water can be added to the tank. Then, the rotating motor 23 drives the stirring blade 21 to rotate. Combined with the cleaning cotton on the stirring blade 21 and the cleaning cotton on the inner wall of the cleaning tank 1, the contact area between the plastic particles and the cleaning cotton is increased. This increases the cleaning area and friction between the plastic particles and the stirring blade 21, facilitating thorough cleaning of the plastic particles. After cleaning, wastewater is discharged through the drain outlet 12 and drain pipe 7 at the bottom of the cleaning tank 1. Finally, the flipping motor 5 rotates the cleaning tank 1 in the clamp 4 by 180°, aligning it with the collection pipe 9 below the cleaning tank 1. The cleaned plastic particles are then transported to the collection box through the collection pipe 9 under gravity, eliminating the need for manual handling of the plastic particles and improving the cleaning efficiency.

[0041] Example 2

[0042] Unlike Embodiment 1, this embodiment also includes a controller. The rotary motor 23, the tilting motor 5, the second electric valve 8, and the third electric valve 10 are all connected to the controller. The controller can automatically control the motors or electric valves to start or stop working, which helps improve the automation level of the cleaning device. The controller is a PLC controller or an embedded controller. The PLC controller uses a programmable memory to store programs and execute user-oriented instructions such as logic operations, sequential control, timing, counting, and arithmetic operations. It controls various types of machinery or production processes through digital or analog input / output. An embedded controller includes electronic devices or devices controlled by microprocessor chips, timers, sequence generators, or controllers, capable of performing various automated processing tasks such as monitoring and control. Both PLC controllers and embedded controllers are commercially available models.

[0043] The other structures are the same as in Embodiment 1, and will not be described again here.

[0044] Example 3

[0045] Unlike Embodiment 1, in this embodiment, the stirring blades 21 are inclinedly mounted on the rotating rod 22, and the inclination angles of adjacent stirring blades 21 may be the same or different. Specifically, there are multiple stirring blades 21, which can be adjusted according to the height of the washing tank 1. The inclination angle of the stirring blades 21 is preferably 60° to 90°, and the inclination angles of adjacent stirring blades 21 are the same. In other embodiments, the inclination angles of adjacent stirring blades 21 may also be different, which can clean plastic particles in different areas of the washing tank 1.

[0046] The other structures are the same as in Embodiment 1, and will not be described again here.

[0047] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope 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.
