Urea for vehicle now uses keg to pack (10L, 20L, 200L plastic barrel), in order not to cause the resource wave in packaging
Take and environmental pollution.The form that American-European countries and domestic southern area are all made of groove body storage outfit charging machine is added
Note；But according to national standard, pure urea for vehicle freezing point has crystalline polamer at subzero 11 degree, and existing loading system does not prevent
Urea for vehicle crystallizes function.It is not available in northern China winter and temperature cold district, charging machine.
For it is above-mentioned the problems of in the prior art, a kind of novel automobile-used urine with heating function of researching and designing
Plain solution loading system, so that it is very necessary for overcoming the problems of in the prior art.
Summary of the invention
Crystalline polamer is had at subzero 11 degree according to pure urea for vehicle set forth above, existing loading system does not prevent
Urea for vehicle crystallizes function, in northern China winter and temperature cold district, the technical issues of charging machine is not available, and mention
For a kind of urea for vehicle solution loading system with heating function.The utility model, which is mainly utilized, increases electromagnetic type to charging machine
The devices such as room are heated, prevent urea crystals phenomenon from generating, change the crystallization of northern and extremely frigid zones urea charging machine to play
Problem.
The technological means that the utility model uses is as follows:
A kind of urea for vehicle solution loading system with heating function, which is characterized in that the loading system includes:
Heating and heat-insulating device and external filling apparatus；
Further, external filling apparatus include: solution efferent duct, electromagnetism sluice valve II, filling gun, solution backflow pipe and
