Description

Technical Field

[0001] This utility model belongs to the field of waste plastic bucket recycling, specifically relating to a device for removing residual liquid from inside buckets. Background Technology

[0002] In the recycling process of 200L waste plastic drums, washing is usually used to clean them. However, due to the special internal structure of plastic drums, it is difficult to completely pour out or drain the cleaning solution after washing, resulting in liquid residue in the drums, which in turn affects the quality of products subsequently stored inside.

[0003] Currently, traditional manual methods are commonly used to remove residual liquid in production. Specifically, operators insert cloth strips into the plastic buckets to absorb the liquid. This method is outdated and inefficient, failing to completely remove the residual liquid. Furthermore, the repeated wiping with cloth strips easily causes secondary contamination of the plastic buckets, affecting the quality of the recycled plastic buckets. In addition, the small opening of the plastic buckets makes the traditional process difficult and labor-intensive for operators. Utility Model Content

This device employs automated technology to vacuum-suck the residual liquid inside the container, improving removal efficiency and effectiveness while preventing secondary contamination of the container. The device is simple and safe to operate; through automated control, operators only need to perform simple operations for the device to automatically complete the residual liquid extraction process, significantly reducing manual labor intensity. The device's reasonable structural design facilitates maintenance and upkeep, thereby reducing subsequent operating costs.

[0005] This utility model achieves the above-mentioned technical effects through the following technical solutions:

The longitudinal beam is located on one side edge of the horizontal surface and is used to support the side wall of the bucket to be processed. A rotating platform is provided above the horizontal surface, and the rotating platform is used to place the bucket to be processed upside down on it. The flipping frame and the base are connected by a flipping hinge.

[0008] The rotary drive unit includes a rotary wheel and a rotary motor for driving the rotary wheel, wherein the outer edge of the rotary wheel abuts against the outer edge of the rotary table;

In the working state, the second cavity and part of the first cavity pass through the rotating table and extend into the interior of the bucket to be treated, and the liquid suction port of the second cavity is located at the corner of the bucket to be treated which is placed upside down.

[0011] In this utility model, the working process of the above-mentioned device to remove residual liquid in the bucket is as follows: the bucket to be treated is placed upside down on the base plate; firstly, one side of the rotating table is lifted by the flipping cylinder, so that the bucket to be treated is tilted to one side, and then the rotating wheel drives the rotating table to rotate, so that the suction gun is aligned with, passes through the rotating table, and extends into the bucket to be treated. By rotating the second chamber, the suction port of the second chamber is positioned at the corner of the upside-down bucket to be treated, and the residual liquid is quickly sucked up.

[0056] S3. Start the rotary motor 4, which drives the rack 805 on the rotary table 8 through the rotary wheel 401, so that the plastic bucket rotates synchronously with the rotary table 8. At the same time, the induction switch 5 ensures the position of the plastic bucket opening so that the plastic bucket opening is aligned with the suction gun assembly 6. The lifting motor 601 in the suction gun assembly 6 drives the lead screw 603 to extend the second cavity 608 and part of the first cavity 607 into the plastic bucket.

[0057] S4. Next, start the suction gun drive motor 604 to open the nozzle of the suction gun assembly 6 by 70° (that is, make the angle between the second chamber 608 and the first chamber 607 70°).

[0058] S5. Continue operating the lifting motor 601 to drive the lead screw 603 and move the first chamber 607 out of the plastic bucket a certain distance, ensuring that the liquid suction port of the first chamber 607 extends below the liquid surface at the corner of the bucket; then start the vacuum pump 11 to suck the residual liquid in the plastic bucket into the intermediate tank 10 through the liquid suction gun assembly 6, thus completing the residual liquid removal operation.

[0059] S6. After completing the operation of removing residual liquid, reset the suction gun assembly 6 and the tilting frame 3 to their initial state.
