Description

Technical Field

[0001] This application relates to the field of docking device technology, and in particular to an anti-tipping and anti-splashing docking device for hazardous waste transfer. Background Technology

[0002] Liquid hazardous waste refers to liquid waste with hazardous characteristics such as corrosivity, toxicity, and flammability. It is a type of hazardous waste and includes categories such as waste acid, waste alkali, waste mineral oil, phenol-containing sludge, and oil-containing mud.

[0003] Currently, within the factory area, it is frequently necessary to pour small containers of hazardous waste into large storage tanks or transfer containers. This process is manually operated and poses two major risks: first, the small containers may not be securely connected to the large-diameter inlet, easily tipping over and causing hazardous waste to spill; second, liquid splashing during pouring can cause chemical injuries to operators. Currently, the process relies heavily on operator experience and personal protective equipment, lacking effective mechanical safety devices.

[0004] Therefore, this application provides an anti-tipping and anti-splashing docking device for hazardous waste transfer. Summary of the Invention

[0058] Specifically, it can drive the vertical slider 408 to move automatically downwards during the rotation of the vertical threaded column 405.

[0059] Please refer to Figure 2 , Figure 4 A second connecting rod 409 is fixedly provided at the end of the vertical slider 408. An installation ring 4010 is fixedly provided at the end of the second connecting rod 409. Three fixing posts 4011 are fixedly provided on the lower surface of the installation ring 4010.

[0061] In this embodiment, by setting up a tilting mechanism 200, a positioning mechanism 300, and a docking mechanism 400, the device can, during actual use, place the mounting frame 100 above the inlet of the hazardous waste transfer drum, then manually lift the small hazardous waste drum 500 and place it in the concave placement tray 301. The dual-axis motor 303 is then started. The rotation of the dual-axis motor 303 drives the two transverse threaded columns 304 to rotate. The rotation of the two transverse threaded columns 304 drives the two transverse sliders 305 to move simultaneously towards the center, thereby driving the two arc-shaped clamping plates 302 to move simultaneously towards the center and effectively clamping and fixing the small hazardous waste drum 500. Simultaneously, during the rotation of one transverse threaded column 304, the two bevel gears 404 drive...

Finally, the drive motor 202 is started to drive the rotating disk 201 to rotate counterclockwise by 180 degrees, so that the hazardous waste container 500 rotates 180 degrees and is inverted. This allows the hazardous waste liquid in the hazardous waste container 500 to automatically flow into the hazardous waste transfer container through the hose 402, achieving the purpose of automatically dumping the hazardous waste container 500. The operation is simple and convenient, avoids liquid spillage, and avoids harm to personnel.

[0062] Example 2

[0063] Based on Example 1, referring to Figures 5 to 8 And unlike Example 1, the following is true:

[0064] Please refer to Figure 5 , Figure 6 The sealing cover 401 is provided with a pressurizing mechanism 600 for pressurizing the inside of the hazardous waste container 500. The pressurizing mechanism 600 includes an arc-shaped tube 601 fixed to the inner wall of the circular hole and an arc-shaped rod 602 slidably disposed on the inner wall of the arc-shaped tube 601. The end of the arc-shaped rod 602 corresponds to a mounting rod 203.

[0065] Specifically, during the rotation of the rotating disk 201, a mounting rod 203 can be driven to rotate around the connecting disk 204, so that the mounting rod 203 can automatically squeeze the end of the arc-shaped rod 602, causing the arc-shaped rod 602 to be retracted into the interior of the arc-shaped tube 601.

[0066] Please refer to Figure 7 , Figure 8An arc-shaped inflatable airbag 603 is fixedly installed on the inner wall of the arc-shaped tube 601. The end of the arc-shaped inflatable airbag 603 is fixedly connected to the end of the arc-shaped rod 602. An arc-shaped return spring 604 is fixedly installed on the inner wall of the arc-shaped inflatable airbag 603. A pressurizing tube 605 and an air intake tube 606 are respectively installed at the ends of the arc-shaped inflatable airbag 603. One end of the pressurizing tube 605 and the air intake tube 606 extends into the interior of the arc-shaped inflatable airbag 603. The other end of the pressurizing tube 605 and the air intake tube 606 extend to the outer surface of the arc-shaped tube 601. A pressurizing one-way valve is installed on the surface of the pressurizing tube 605, and a filter cover is installed at the other end of the air intake tube 606. An air intake one-way valve is installed on the surface of the air intake tube 606.

[0067] Specifically, during the process of the arc-shaped rod 602 retracting into the arc-shaped tube 601, the arc-shaped inflatable airbag 603 inside the arc-shaped tube 601 can be automatically squeezed. At the same time, the arc-shaped return spring 604 and the suction tube 606 facilitate the reset of the arc-shaped rod 602 and the arc-shaped inflatable airbag 603.

[0068] Please refer to Figure 7 , Figure 8 The mounting ring 4010 has an annular cavity inside, the other end of the pressurizing tube 605 extends into the annular cavity, and an inflation tube 607 is fixed on the surface of the mounting ring 4010. The top end of the inflation tube 607 extends into the annular cavity, the bottom end of the inflation tube 607 extends into the sealing cover 401, and an inflation one-way valve is provided on the surface of the inflation tube 607.

[0069] Specifically, after the arc-shaped inflatable airbag 603 is compressed, the air inside the arc-shaped inflatable airbag 603 can enter the annular cavity through the pressurization pipe 605, and then enter the sealed hazardous waste container 500 through the inflation pipe 607.

[0070] In this embodiment, by setting up a pressurizing mechanism 600, during the process of the rotating disk 201 and the fixed hazardous waste container 500 rotating 180 degrees due to the rotation of the drive motor 202, when the rotating disk 201 rotates to 110 degrees, a mounting rod 203 inside the circular hole can contact the end of the arc-shaped rod 602. At this time, the hazardous waste container 500 rotates to a tilted and inverted state. When it continues to rotate, the mounting rod 203 can squeeze the arc-shaped rod 602, causing the arc-shaped rod 602 to... 02 is drawn into the arc-shaped tube 601. During this process, the arc-shaped rod 602 can compress the arc-shaped inflatable airbag 603 inside the arc-shaped inflatable airbag 603, allowing the air inside the arc-shaped inflatable airbag 603 to enter the annular cavity through the pressurization tube 605, and then enter the hazardous waste container 500 through the inflation tube 607, thereby pressurizing the inside of the hazardous waste container 500. This allows the liquid inside the hazardous waste container 500 to quickly flow into the hazardous waste transfer container through the hose 402, improving work efficiency.

[0071] Working principle:

[0072] During the process of transferring the liquid from the small hazardous waste container 500 to the large hazardous waste transfer container, the mounting frame 100 is first placed above the inlet of the large hazardous waste transfer container. Then, the small hazardous waste container 500 is lifted and placed in the concave placement tray 301. Next, the dual-axis motor 303 is started. The rotation of the dual-axis motor 303 drives the two transverse threaded columns 304 to rotate. The rotation of the two transverse threaded columns 304 drives the two transverse sliders 305 to move simultaneously towards the center, thereby driving the two arc-shaped clamping plates 302 to move simultaneously towards the center and effectively clamp and fix the small hazardous waste container 500. During the rotation of a horizontal threaded column 304, the connecting shaft 403 is driven to rotate by the two bevel gears 404. The rotation of the connecting shaft 403, under the action of the two transmission wheels 406 and the transmission belt 407, drives the vertical threaded column 405 to rotate. The rotation of the vertical threaded column 405 drives the vertical slider 408 to move downward, thereby driving the mounting ring 4010 and the sealing cover 401 to move downward, so that the sealing cover 401 effectively seals the top of the hazardous waste container 500. Finally, the drive motor 202 is started to drive the rotating disk 201 to rotate counterclockwise by 180 degrees, so that the hazardous waste container 500... The container 500 is rotated 180 degrees and inverted, allowing the hazardous waste liquid inside to automatically flow into the large hazardous waste transfer container through the hose 402, thus achieving automatic tilting of the container 500. This is simple and convenient to operate, preventing liquid spillage and avoiding harm to personnel. Furthermore, during the 180-degree rotation of the rotating disk 201 and the fixed hazardous waste container 500 driven by the drive motor 202, when the rotating disk 201 rotates to 110 degrees, a mounting rod 203 inside the circular hole contacts the end of the arc-shaped rod 602, at which point the hazardous waste container 500 rotates to its tilted position. When the device is tilted and rotated, the mounting rod 203 can compress the arc-shaped rod 602, causing it to retract into the arc-shaped tube 601. During this process, the arc-shaped rod 602 can compress the arc-shaped inflatable airbag 603 inside the arc-shaped tube 601, allowing the air inside the arc-shaped inflatable airbag 603 to enter the annular cavity through the pressurization pipe 605 and then enter the hazardous waste container 500 through the inflation pipe 607. This pressurizes the inside of the hazardous waste container 500, allowing the liquid inside the hazardous waste container 500 to quickly flow into the hazardous waste transfer container through the hose 402, thus improving work efficiency.
