Description

Technical Field

[0001] This utility model relates to the field of residual acid recovery technology for loading arms, and in particular to a residual acid recovery device applied to automatic acid loading arms. Background Technology

[0002] Currently, before acid is loaded onto acid tank trucks, the connecting sleeve (automatic acid loading arm) is installed manually at the outlet of the acid loading pipeline. After the acid is loaded, the connecting sleeve is removed manually, and then the residual acid spilled from the connecting sleeve needs to be cleaned and rinsed.

[0003] Currently, existing automatic acid loading arms have been found to have at least the following technical problems in actual use;

[0004] After the existing automatic acid loading arms load acid into the acid storage truck, residual acid drips onto the ground from its outlet, requiring manual cleaning. During the cleaning process, the acid may injure the workers, posing a safety hazard. At the same time, the dripping acid may corrode nearby equipment, resulting in waste and increased production costs. Cleaning up the dripping acid also increases the workload for workers. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a residual acid recovery device for automatic acid loading arms, solving the problems of increased labor, material waste, and safety hazards associated with existing automatic acid loading arms.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A residual acid recovery device for automatic acid loading arms includes an automatic acid loading arm body, which is connected to an external loading arm frame. A collection tray is provided at the discharge end of the automatic acid loading arm body, and a through groove is opened on the surface of the collection tray. A drive mechanism is provided at the bottom of the collection tray, and a reflux mechanism is provided between the collection tray and the automatic acid loading arm body. The drive mechanism includes a servo motor, and a rotating frame is fixedly connected to the output end of the servo motor. The servo motor is fixedly connected to the bracket of the external device. The entire device is controlled by the controller of the external device. The reflux mechanism includes a reflux hose, and the two ends of the reflux hose are an inlet and an outlet, respectively.

[0008] Preferably, the bottom of the collection tray is funnel-shaped, and the return hose is fixedly connected to the bottom surface of the collection tray through the liquid inlet.

[0009] Preferably, the reflux hose is fixedly connected to the automatic acid loading arm body through the liquid outlet.

[0010] Preferably, a support plate is provided at the end of the rotating frame away from the servo motor, and the inner wall of the support plate is funnel-shaped.

[0011] Preferably, the collection tray is placed on top of the support tray.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The automatic acid loading arm is positioned inside the collection tray. The through-slot allows the automatic acid loading arm to pass through. Residual acid dripping from the automatic acid loading arm is collected by the collection tray. The residual acid gathers in the funnel at the bottom of the collection tray and flows back to the return hose. It flows back from the inlet end to the outlet end of the return hose and finally flows into the automatic acid loading arm, preventing residual acid from dripping onto the ground. This eliminates the need for manual cleaning, saves labor, and reduces the danger caused by residual acid. It solves the problems of increased labor and safety hazards associated with existing automatic acid loading arms.

[0015] Second, by returning the residual acid to the body of the automatic acid loading arm, not only is the danger of residual acid generation avoided, but the material is also structured, avoiding waste and solving the problem of material waste in existing automatic acid loading arms.

[0022] This application provides a residual acid recovery device for automatic acid loading arms, which effectively solves the problems of increased labor, material waste, and safety hazards associated with existing automatic acid loading arms. Example

[0023] like Figure 1-4 As shown, the technical solution in this application embodiment effectively solves the technical problems of existing automatic acid loading arms increasing labor intensity, wasting materials, and posing safety hazards. The overall idea is as follows:

[0024] To address the problems existing in the prior art, this utility model provides a residual acid recovery device for automatic acid loading arms, including an automatic acid loading arm body 5, which is connected to an external loading arm frame. A collection tray 1 is provided at the discharge end of the automatic acid loading arm body 5, and a through groove 101 is opened on the surface of the collection tray 1. A drive mechanism is provided at the bottom of the collection tray 1, and a reflux mechanism is provided between the collection tray 1 and the automatic acid loading arm body 5. The drive mechanism includes a servo motor 3, and a rotating frame 4 is fixedly connected to the output end of the servo motor 3. The servo motor 3 is fixedly connected to the external bracket. The entire device is controlled by the external controller. The reflux mechanism includes a reflux hose 2, and the two ends of the reflux hose 2 are an inlet 6 and an outlet 7, respectively.

[0025] The bottom of the collection tray 1 is funnel-shaped, and the return hose 2 is fixedly connected to the bottom surface of the collection tray 1 through the liquid inlet 6.

[0026] The return hose 2 is fixedly connected to the automatic acid loading arm body 5 through the liquid outlet 7.

[0027] A support plate 401 is provided at the end of the rotating frame 4 away from the servo motor 3, and the inner wall of the support plate 401 is funnel-shaped.

[0028] The collection tray 1 is placed on the top surface of the support tray 401.

[0029] The bottom of the automatic acid loading arm body 5 is higher than the bottom of the through groove 101.

[0030] Collection tray 1: Collects residual acid dripping from the automatic acid loading arm 5. The funnel-shaped design at the bottom facilitates the collection of residual acid.

[0031] Return hose 2: Returns the residual acid collected in the collection tray 1 to the automatic acid loading arm body 5, the inlet 6 collects the residual acid, and the outlet 7 delivers the residual acid.

[0032] Servo motor 3: provides power for the rotation of the rotating frame 4, driving the collection tray 1 to rotate and reset.

[0033] Rotating frame 4: Driven by servo motor 3, it rotates and moves the collection tray 1 to a suitable position to collect residual acid or reset it.

[0034] Automatic acid loading arm body 5: Used to load acid into acid tank trucks, and its own pump body can suck up residual acid from the return hose 2.

[0035] Inlet 6: The port on the return hose 2 for collecting residual acid from the collection tray 1.

[0036] Outlet 7: The port on the reflux hose 2 that supplies residual acid to the automatic acid loading arm 5.

[0038] Support plate 401: Supports the collection tray 1, and its inner wall is funnel-shaped to facilitate the flow of residual acid.

[0039] Working principle:

[0040] After the acid tanker is loaded with acid through the automatic acid loading arm 5, residual acid will drip from its outlet. At this time, the servo motor 3 drives the rotating frame 4 to rotate 90 degrees, which in turn drives the collection tray 1 to rotate 90 degrees, so that the automatic acid loading arm 5 is located inside the collection tray 1. The passage 101 is opened to allow the automatic acid loading arm 5 to pass through. The residual acid dripping from the automatic acid loading arm 5 will be collected by the collection tray 1. The residual acid will converge in the funnel at the bottom of the collection tray 1 to the return hose 2. It will flow back from the inlet 6 end of the return hose 2 to the outlet 7 end of the return hose 2, and finally flow into the automatic acid loading arm 5 (the automatic acid loading arm 5 itself has a pump structure, which can suck up the residual acid from the collection tray 1 through the return hose 2). Before the acid tanker travels under the automatic acid loading arm 5, the servo motor 3 automatically controls the collection tray 1 to reset and disengage from the automatic acid loading arm 5.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
