Low-temperature-resistant urea filling machine for vehicles

Abstract

The invention provides a low-temperature-resistant vehicle urea filling machine, and belongs to the technical field of filling machines, the low-temperature-resistant vehicle urea filling machine comprises a machine shell, a heat preservation layer is fixedly connected to the inner side wall of the machine shell, a storage tank used for storing urea is installed in the machine shell, and a sensor used for measuring the remaining amount of urea is arranged on the storage tank; one side of the machine shell is provided with an equipment chamber used for installing electric appliance parts, the rear side of the equipment chamber is fixedly connected with an installation frame, and the installation frame is provided with a filling and liquid supplementing system used for filling and supplementing urea; according to the invention, the heat preservation effect is good, self-heating can be realized, normal filling of the filling machine is ensured, the traditional double pumps are improved into the single pump, the production cost is greatly reduced, and the internal structure is optimized.

Description

technical field [0001] The invention relates to the technical field of filling machine equipment, in particular to a low-temperature resistant vehicle urea filling machine. Background technique [0002] At present, 76% of the total domestic freight is completed by road transport, and the main force of road transport is medium and heavy-duty diesel trucks, and the tail gas emitted by these diesel trucks has reached 56% of the total air pollution. With the increasing importance of domestic environmental protection, the requirements for diesel truck exhaust emissions are getting higher and higher, and the main reducing reaction substance for treating diesel truck exhaust is vehicle exhaust purification fluid. As the main filling equipment for diesel trucks to fill vehicle exhaust purification fluid, the vehicle exhaust purification fluid filling machine (hereinafter referred to as "normal temperature filling machine") came into being, which alleviated the domestic diesel trucks...

AI Technical Summary

Problems solved by technology

Affected by the crystallization point of the vehicle exhaust purification fluid itself (crystallization occurs at -11°C), when the temperature reaches -11°C, the active components of the vehicle exhaust purification fluid in the normal temperature filling machine begin to form crystals and precipitate and settle, and the solvent begins to freeze , not only makes the filling equipment unable to work normally, but also greatly reduces the quality of the vehicle exhaust purification fluid stored inside

Even if the temperature rises and the solution is thawed, there will be too much solvent in the vehicle exhaust purification fluid, so that it will not be able to fully reduce the exhaust gas produced by diesel trucks, and the quality of the vehicle exhaust purification fluid cannot be guaranteed. The normal temperature filling machine cannot be used normally for filling in these areas due to the impact of the low temperature period
