Description

Technical Field

[0001] This utility model belongs to the field of resource recycling and utilization, and in particular relates to a polytetrafluoroethylene pull-out waste liquid recycling box. Background Technology

[0002] Polytetrafluoroethylene (PTFE) waste liquid typically refers to waste liquid containing PTFE generated during the production, processing, or use of PTFE materials. Improper handling of this waste liquid can not only waste resources but also pollute the environment. Therefore, it is essential to collect it using dedicated waste liquid recycling bins.

[0003] In routine laboratory operations, ordinary PTFE waste liquid recovery boxes typically contain multiple recovery containers and are placed below the equipment's infusion port to collect leaks generated during titration. However, during actual use, when waste liquid drips from the infusion port into the recovery containers, residual droplets often adhere to the edge of the container opening and fail to fall completely into the designated container. This causes waste liquid to leak into the internal area of ​​the recovery box, resulting in contamination. Furthermore, to achieve a reasonable layout of multiple recovery containers, the internal structure of the recovery box is relatively compact, with limited space and many corners and gaps, making it difficult for cleaning tools to thoroughly clean it. This results in residual waste liquid being difficult to remove, and long-term accumulation can easily lead to cross-contamination and bacterial growth, affecting the cleanliness of the experimental environment and the normal use of the equipment.

[0004] Therefore, there is a particular need for a polytetrafluoroethylene (PTFE) pull-out waste liquid recycling box to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of ordinary PTFE waste liquid recycling boxes, which have a compact structure, dead corners for cleaning, difficulty in removing residual waste liquid, and are prone to cross-contamination, bacterial growth, and impact on the experimental environment and equipment use, this utility model provides a pull-out PTFE waste liquid recycling box.

[0006] This utility model is achieved through the following technical means: a polytetrafluoroethylene pull-out waste liquid recycling box, including a mounting shell, a pull-out frame, a limiting ring assembly, a pull-out rod, and a connecting ring assembly. Two mounting holes are opened on each of the four sides of the lower part of the mounting shell. The pull-out frame is slidably placed inside the mounting shell. The limiting ring assembly is fixedly connected to the inside of the pull-out frame. Two pull-out rods are arranged side by side and fixedly connected to one side of the pull-out frame. The connecting ring assembly is fixedly connected to the top of the limiting ring assembly.

[0007] To further explain, it also includes a support rod and a cover plate. The support rod is fixed to one side of the connecting ring assembly, and multiple cover plates are rotatably mounted on the support rod, with the multiple cover plates forming a cover plate assembly together.

[0008] To further explain, it also includes sealing gaskets, with multiple sealing gaskets evenly distributed on each cover plate, the number of sealing gaskets being consistent with the number of slots placed on the connecting ring assembly.

[0009] To further explain, it also includes limiting plates. Multiple limiting plates are fixed to the support rod and distributed along its length. The multiple limiting plates are located at the lower rear of multiple cover plates.

[0010] To further explain, the cylindrical surface of each pull rod has been treated with an anti-slip coating.

[0011] To further explain, the top surface of each limiting plate is covered with a cushioning pad.

[0012] Beneficial effects: 1. By adopting a modular recycling box structure design, the limiting ring assembly and connecting ring assembly used to place the recycling container can be easily disassembled and assembled. This design greatly facilitates comprehensive and in-depth cleaning of the recycling box, effectively reducing waste liquid residue and dirt accumulation, ensuring that the recycling box is always clean and hygienic, thereby extending its service life.

[0013] 2. By setting a cover plate and a sealing gasket, the cover plate can effectively block the opening area on the connecting ring assembly where the recycling container is placed, while the sealing gasket fits tightly against the contact area between the cover plate and the recycling container. The two work together to provide reliable sealing protection for the recycling container and prevent the evaporation or leakage of waste liquid. Attached Figure Description

[0020] Example: A polytetrafluoroethylene (PTFE) pull-out waste liquid recovery box, such as... Figures 1-5As shown, the device includes a mounting shell 1, a pull-out frame 3, a limiting ring assembly 4, pull-out rods 5, and a connecting ring assembly 6. The mounting shell 1 has two mounting holes 2 on each of its four sides (front, back, left, and right). The pull-out frame 3 is slidably placed inside the mounting shell 1. The limiting ring assembly 4 is adhered to the inside of the pull-out frame 3. Two pull-out rods 5 are arranged side-by-side and adhered to the left side of the pull-out frame 3. The cylindrical surface of each pull-out rod 5 is treated with anti-slip material (such as anti-slip textures or an anti-slip coating) to increase the friction between the operator's hand and the pull-out rod 5, facilitating the pull-out operation. The connecting ring assembly 6 is adhered to the top of the limiting ring assembly 4.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, it also includes a support rod 7, a cover plate 8, a sealing gasket 9, and a limiting plate 10. The support rod 7 is bonded to the rear side of the connecting ring assembly 6, and five cover plates 8 are rotatably mounted on the support rod 7. The five cover plates 8 together form a cover plate assembly. Five sealing gaskets 9 are bonded to each cover plate 8 at equal intervals. The number of sealing gaskets 9 is consistent with the number of slots on the connecting ring assembly 6. Five limiting plates 10 are bonded to the support rod 7 and distributed along its length. The five limiting plates 10 are located behind the lower part of the five cover plates 8. The top surface of each limiting plate 10 is covered with a buffer pad to ensure that when the cover plate 8 is pressed against the top surface of the limiting plate 10, it can play a buffering role and reduce the collision and wear between the cover plate 8 and the limiting plate 10.

[0022] When the recycling box is needed, the operator first places the mounting shell 1 below the infusion port of the equipment, then fixes the mounting shell 1 in a suitable position through the mounting hole 2, and then rotates the cover plate 8 counterclockwise to make room for operation above the connecting ring assembly 6. When the cover plate 8 is rotated to 90 degrees and is in a horizontal position, the top surface of the limiting plate 10 will abut against the cover plate 8 to limit its continued rotation and ensure that the cover plate 8 is in a stable state. Then, the recycling container is placed between the limiting ring assembly 4 and the connecting ring assembly 6 in sequence to collect the leakage generated during the titration process.

[0023] After collection, remove the recycling containers one by one, hold the pull rod 5 to pull the pull frame 3 out of the mounting shell 1, remove the limiting ring assembly 4 and the connecting ring assembly 6, then clean the parts contaminated by waste liquid in the recycling box. After cleaning, put the pull frame 3 back into the mounting shell 1, put back the limiting ring assembly 4 and the connecting ring assembly 6, and finally put the recycling containers back between the limiting ring assembly 4 and the connecting ring assembly 6 one by one. Rotate the cover plate 8 clockwise 180 degrees so that the cover plate 8 covers the connecting ring assembly 6. At this time, the sealing gasket 9 contacts the corresponding recycling container to achieve the sealing of the recycling container and prevent the waste liquid from evaporating or leaking.
