Description

Technical Field

[0001] The utility model mainly relates to the technical field of urea processing, and in particular to a vehicle urea feed liquid mixing mechanism. Background Art

[0002] Automotive urea is a liquid that uses SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Ordinary urea is composed of 32.5% high-purity urea and 67.5% deionized water. The urea solution and nitrogen oxides in the exhaust gas undergo redox reactions in the SCR reactor to generate nitrogen and water for discharge, achieving the purpose of environmental protection.

[0003] The existing patent publication number CN 210252130U discloses a high-efficiency automotive urea solution production mixer, which includes a tank body, which is provided with a feed port and a discharge port, and the tank body is provided with a crushing chamber, a mixing chamber and a cavity from top to bottom in sequence, a grinding head is provided in the crushing chamber, the grinding head is fixedly connected to a first rotating shaft, the other end of the first rotating shaft is fixedly connected to the output end of the first motor through a coupling, a filter is provided on one side of a separation plate close to the feed port, and a plurality of screening holes are provided on the separation plate, a first tube body fixedly connected to the inner wall of the tank body is provided in the mixing chamber, an atomizing nozzle is installed on one side of the bottom of the first tube body, and a stirring device is also provided in the tank body, including a stirring head assembly and a driving mechanism, and the stirring head assembly is located in the mixing chamber.

[0004] During the implementation process, the inventor found that since the stirring component is arranged on the bottom surface of the tank body, the sealing requirements are high. At the same time, a small amount of urea particles will be deposited on the bottom surface of the tank body during the stirring process of the stirring component, resulting in insufficient mixing of the feed and liquid and low mixing efficiency. On this basis, while meeting the diversified development of the market, a vehicle urea feed-liquid mixing mechanism is proposed. Utility Model Content
