Preferably, the solar heat collector is a wall-mounted solar heat collector plate, and the working medium therein is a low temperature resistant liquid.

Preferably, the heating layer is one of a coil or an interlayer.

Preferably, the outer side of the heating layer is sequentially wrapped with a thermal insulation layer and a protective layer.

Preferably, a pressure relief device is provided on the water outlet pipeline of the heating layer.

Preferably, the homogeneous stirring tank is provided with a urea raw material inlet, a deionized water inlet, a solution outlet and a stirring device, the upper part of the homogeneous stirring tank is provided with a urea raw material inlet and a deionized water inlet, and the lower part of the homogeneous stirring tank is provided with a solution At the outlet, a stirring shaft is arranged in the homogeneous stirring tank, the stirring shaft is connected with stirring blades, and the stirring shaft is also connected with a stirring drive motor.

The wall-mounted solar heat collector absorbs solar energy, which makes the temperature of the working medium inside it rise, and the high-temperature working medium transfers heat to the water circulating in the pipeline, so that the temperature of the water rises, and the heated water passes through the heating layer , transfer the heat to the homogeneous stirring tank and heat the urea solution. The water is forced to flow under the action of the circulation pump, and flows through the hot water outlet, the circulation pump, the water inlet pipeline, the heating layer, the water outlet pipeline, the circulation return water outlet and the circulation pump in sequence.

Since the system composed of the heating layer, the water inlet pipeline, the water outlet pipeline, the hot water outlet, and the circulating water outlet is a closed structure, a pressure relief device is installed on the water outlet pipeline of the heating layer, and the pressure relief device can be adjusted according to the working pressure of the system. Automatic opening and closing to ensure the safe operation of closed pipelines.

The vehicle urea heating device of the utility model has the advantages of simple structure and rapid heating, and can meet the heating requirement of the urea solution preparation process. Its beneficial effects are as follows:

(1) The urea solution heating device of the present utility model belongs to the non-contact heating device, and has a simple overall structure, and the heating part does not directly contact with the urea solution, thus avoiding secondary pollution caused during the solution preparation process.

(2) The urea solution heating device of the present invention uses a solar heat collector as a heat source, cooperates with a heating layer to supply the heat required for urea dissolution, and has sufficient energy and is environmentally friendly.

(3) In the urea solution heating device of the present utility model, circulating pumps are respectively installed at the hot water outlet and the circulating water return port of the solar collector, so that the water in the heating layer and the pipeline is forced to convect, which greatly improves the heating efficiency. s efficiency.
