The urea granule production line is directly added with equipment and working procedures for preparing urea aqueous solution, so that the waste of manpower and consumables can be reduced, but the inside of the equipment for preparing the aqueous solution is in a vacuum state, and the prepared aqueous solution cannot be directly output to the configuration groove by using a pipeline.
Disclosure of Invention
In order to transport the prepared urea aqueous solution to a configuration tank of the next process, the utility model provides a urea aqueous solution transport system.
The urea aqueous solution transportation system is connected to the bottom of a pre-evaporation separator of a urea production device and is characterized by comprising a storage tank, a solution pump and a conveying pipeline, wherein the top of the storage tank is communicated with the urea production device through a liquid inlet pipe, a first valve is arranged on a liquid inlet pipe path, the upper part of the storage tank is connected with a vacuum pump through an exhaust pipe, a second valve is arranged on the exhaust pipe path, the bottom of the storage tank is communicated with a liquid outlet pipe, a third valve is arranged on the liquid outlet pipe path, the liquid outlet pipe is communicated with the liquid outlet pipe, one end of the liquid outlet pipe is connected with a liquid inlet of the solution pump, one end of the liquid outlet pipe is connected with the storage tank of the urea production device, a fourth valve is arranged on the liquid outlet pipe between the storage tank of the urea production device and the third valve, a fifth valve is arranged on the liquid outlet pipe between the third valve and the solution pump, the liquid outlet of the solution pump is communicated to a configuration groove through a pipeline, a sixth valve is arranged on the pipeline path, a flushing pipe is connected on the liquid outlet pipe between the third valve and the fifth valve, and a seventh valve is arranged on the flushing pipe path.
The volume of the sump and 2 m.
The utility model has the beneficial effects that: the position connected with the urea production device is vacuum, so that stable operation of the system is ensured, and the operation of the connected urea production device is not influenced, and therefore, the system is required to be used for transporting the urea aqueous solution to a configuration tank of a next process. And the system has a flushing function, and the system pipeline is flushed before the system stops after production, so that urea crystals are prevented from blocking the pipeline. When the system is not in use, the valve can be closed to disconnect the system from the urea production device, so that the urea production device is not influenced to produce other types of urea products.
