Adblue solution stirring device and temperature control method thereof

Abstract

The invention discloses an adblue solution stirring device and a temperature control method thereof. The adblue solution stirring device comprises a stirring box (3), a heating device (4), a temperature detection device used for detecting the temperature of a solution in the stirring box (3), a circulation loop arranged on the outer side of the stirring box (3), a circulating pump (1) connected to the circulation loop in series and a switching valve (2) which is connected to the circulation loop in series and has an adjustable opening degree, wherein the temperature detection device is in communication connection with the heating device (4); the two ends of the circulation loop are both communicated with the interior of the stirring box (3); the circulating pump (1) and the switching valve (2) are in communication connection with the temperature detection device. According to the adblue solution stirring device, through arrangement of the switching valve with the adjustable opening degree, the temperature of the solution in the stirring box can be controlled conveniently, so that constant temperature control over the solution in the stirring box is achieved, and product quality is effectively improved.

Description

technical field [0001] The invention relates to the technical field of urea equipment, in particular to a vehicle-used urea solution stirring device and a temperature control method thereof. Background technique [0002] At present, the vehicle urea solution (hereinafter referred to as the solution) is formed by dissolving in a stirring tank. In order to promote the dissolution of urea, a heating device is provided in the stirring box to heat the solution inside it. [0003] In order not to affect the quality of urea, the solution temperature should not be too high. However, the solution in the stirring tank is only heated by the heating device for single control. When the temperature of the solution is higher than the preset temperature, it is difficult to cool down. It is more convenient to effectively control the temperature of the solution in the stirring tank. The constant temperature environment cannot be achieved, which seriously affects the product quality. [000...
