Description

Urea recovery filling device for engine test Technical Field The utility model relates to the technical field of engines, in particular to a urea recovery filling device for an engine test. Background Engines during testing, urea is typically required to be added to the engine. Most of the existing urea tanks are in different shapes, the bottom of the existing urea tank is provided with a drain bolt, when the residual urea liquid in the urea tank is recovered, the urea tank can be drained and recovered after being lifted, but because the diameter of a solution inlet of the urea tank is only 22mm, if the drain bolt of the old urea tank is directly aligned to a new urea tank, urea in the old urea tank is discharged to the new urea tank, the urea tank is difficult to pour, recycling is very difficult, and the urea tank can only be generally poured, so that the problem of resource waste is caused. If the residual urea solution in the urea tank is poured into a container such as a barrel, the residual urea solution is difficult to refill into the urea tank of the engine for recycling. Therefore, there is a need to design a urea recovery and filling device for engine tests. Disclosure of utility model The utility model aims to solve the technical problems of the prior art, and provides the urea recovery filling device for the engine test, which realizes the effective utilization of residual urea liquid, effectively avoids the waste of resources and reduces the production cost.
