Abstract
Description
Technical Field
[0001] This application relates to the field of ammonia loading technology, and in particular to an ammonia loading arm. Background Technology
[0002] As is well known, when ammonia is loaded onto trucks, a large amount of gas is easily released from the tank opening due to pressure. This gas is highly irritating and has a wide diffusion area, posing a significant hazard to human health and the surrounding environment.
[0003] Currently, when loading liquid ammonia, the liquid ammonia shut-off valve automatically closes when the liquid ammonia tanker reaches the set filling volume. At this time, it is also necessary to close the liquid ammonia tanker loading valve and remove the loading arm. Since the loading arm and the liquid ammonia tanker have the same pressure, the residual ammonia in the loading arm needs to be emptied or recycled before removal, which inevitably causes environmental pollution. Therefore, it is very necessary to recycle and reuse the residual liquid ammonia in the loading arm.
[0004] Therefore, in response to the aforementioned technologies, we propose an ammonia loading arm. Utility Model Content
[0005] The purpose of this invention is to provide an ammonia loading arm to solve the problems mentioned in the background art.

[0008] Base;
[0009] A support column is fixedly connected to a base, and two connecting blocks are fixedly connected to one end of the support column. A connecting shaft is rotatably provided between the connecting blocks.
[0010] A connecting plate is fixedly connected to a connecting shaft, and the other end of the connecting plate is fixedly connected to the loading arm body via a connecting seat. An adjusting valve is provided on the loading arm body.
[0011] A connecting pipe is connected to the main body of the loading arm, and the other end of the connecting pipe is connected to a transmission pipe. A solenoid valve is installed on the transmission pipe, and a rotary joint is installed at one end of the transmission pipe.
[0012] Mounting plate, the mounting plate is fixedly connected to one end of the support column by a support plate, and a liquid pump is fixedly connected to the mounting plate;

[0014] A recovery component is provided at the output end of the liquid pump and is used to recover the ammonia water remaining in the connecting pipe.
[0015] The mounting component is disposed within the base and is used to securely mount the base in the usage position.
[0016] As a further embodiment of this utility model: the recycling component includes a residual tube, which is connected to the output end of the liquid pump, and a flow valve is provided on the residual tube. The other end of the residual tube is detachably connected to a recycling bottle via a rotating ring.
[0017] As a further improvement of this utility model: the mounting assembly includes four mounting rings, all of which are disposed in the base through mounting holes, and mounting bolts are threaded into the mounting rings.
[0018] As a further improvement of this utility model, the connecting pipe is connected to the main body of the loading arm via a connecting ring.
[0019] As a further improvement of this utility model, the recycling pipe is connected to the transmission pipe through a sealing ring.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] By setting up the installation components, the base is fixed in the usage position with the cooperation of the installation ring and installation bolts. Then, the loading arm body is rotated to the appropriate position through the cooperation of the connecting block, connecting shaft, connecting plate and connecting seat. The loading arm body is then connected to the tank truck through the rotary joint on the transfer pipe.

After loading is completed, the regulating valve and solenoid valve can be closed, and the liquid pump on the installation plate can be started. With the cooperation of the liquid pump, recovery pipe and residual pipe, the liquid ammonia remaining in the connecting pipe and transfer pipe is pumped into the recovery bottle, which realizes the function of recovering the residual liquid ammonia. Its overall structure is relatively simple, which facilitates the transfer of liquid ammonia into the tank truck. It has high flexibility of use, and compared with the existing technology, it is easier to recover the residual liquid ammonia in the pipe, avoiding the release of residual liquid ammonia in the pipe into the air and causing environmental pollution.

After loading is completed, the regulating valve 8 and solenoid valve 11 are closed, and the liquid pump 15 on the mounting plate 13 is started. With the cooperation of the liquid pump 15, recovery pipe 16, and residual pipe 17, the liquid ammonia remaining in the connecting pipe 9 and transmission pipe 10 is pumped into the recovery bottle 20, thereby achieving the purpose of recovering the residual liquid ammonia.
