Description

Technical Field

[0001] The utility model mainly relates to the field of vehicle urea production, and in particular to a vehicle urea solution purification device with a filtering function. Background Art

[0002] Automotive urea, also known as diesel exhaust fluid, is a liquid specifically used in diesel engines;

[0003] Its main function is to reduce the emission of nitrogen oxides in diesel vehicle exhaust. Through SCR (selective catalytic reduction) technology, nitrogen oxides are converted into harmless nitrogen and water vapor, thereby reducing environmental pollution. Automotive urea is usually mixed with high-purity urea and ultrapure water in a certain proportion, in which the concentration of urea is generally 32.5%, and the rest is deionized water;

[0004] When automotive urea is mixed with pure water, the urea solution will become turbid, and the automotive urea solution needs to be purified by a purification device.

[0005] The inventor discovered the following defects during the operation of the specific embodiment:

[0006] However, during the process of purifying urea solution by the purification device, impurities are easily attached to the inside of the purification device and block the outlet of automotive urea. The purification device needs to be opened regularly to clean the internal impurities, resulting in a decrease in the efficiency of the purification device in purifying automotive urea.

[0007] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0032] The purification structure 5 includes a placement bin 501, a reverse osmosis membrane 502 is arranged on one side outer wall of the placement bin 501, a connecting pipe 503 is arranged at the bottom of the placement bin 501, a sealing ring 504 is arranged at the bottom of the connecting pipe 503, the sealing ring 504 is slidably connected to the top of the mounting ring 3, an electromagnetic valve is arranged inside the connecting pipe 503, the number of the placement bins 501 is set to two, an installation shaft 505 is arranged between the two placement bins 501, the installation shaft 505 is rotatably connected to the bottom of the inner wall of the purification shell 1, and a planar volute spring 506 is arranged between the installation shaft 505 and the purification shell 1.

[0033] Furthermore, electric telescopic rods 6 are provided on both sides of the outer wall of the purification shell 1, and a sealing cover 7 is provided between the two electric telescopic rods 6. The sealing cover 7 is provided directly above the purification shell 1. Through the provided electric telescopic rods 6, the electric telescopic rods 6 can drive the sealing cover 7 to rise and fall, so as to open and close the purification shell 1.

[0034] Furthermore, a servo motor 8 is provided at the output end of the sealing cover 7 , and auxiliary grooves 12 are provided on both sides of the top of the sealing cover 7 .

[0035] Furthermore, a transmission shaft 9 is provided at the output end of the servo motor 8, and the transmission shaft 9 is rotatably connected to the inner wall of the through hole in the middle of the sealing cover 7. Rotating shafts 10 are provided on both sides of the bottom of the transmission shaft 9. The rotating shaft 10 is rotatably connected to the transmission shaft 9, a spring is provided between the rotating shaft 10 and the transmission shaft 9, and a push rod 11 is provided on the outer wall of the rotating shaft 10. When the servo motor 8 is started, the servo motor 8 drives the transmission shaft 9 to rotate, and the transmission shaft 9 drives the push rod 11 on the outer wall of the rotating shaft 10 to fit the outer wall of the placement bin 501 and push the placement bin 501 to rotate, and the placement bin 501 squeezes the planar volute spring 506. When the planar volute spring 506 overcomes the springs of the rotating shaft 10 and the transmission shaft 9, the planar volute spring 506 resets and pushes the placement bin 501 through the push rod 11, so that the push rod 11 rotates, and the placement bin 501 vibrates, and the vibration causes the internal automotive urea solution to shake.

[0036] Furthermore, a pressure plate 507 is slidably connected to the interior of the placement bin 501, and liquid inlet pipes 508 are provided on both sides of the top of the pressure plate 507. The outer walls of the liquid inlet pipes 508 are in contact with the inner walls of the auxiliary groove 12. The liquid inlet pipe 508 on one side of the top of the pressure plate 507 is used to introduce automotive urea into the interior of the placement bin 501, and the liquid inlet pipe 508 on the other side is used to pump other urea into the interior of the placement bin 501, and a solenoid valve is provided inside the liquid inlet pipe 508, so that only one liquid inlet pipe 508 is opened at a time.

[0037] In this embodiment, when the vehicle urea solution needs to be purified by the purification device, the vehicle urea enters the interior of the storage bin 501 through the liquid inlet pipe 508, and then the solenoid valve in the liquid inlet pipe 508 on one side closes the liquid inlet pipe 508, and the liquid inlet pipe 508 on the other side pumps high-pressure gas into the interior of the storage bin 501 through a pump, so that the vehicle urea solution in the storage bin 501 passes through the reverse osmosis membrane 502 and enters the interior of the purification shell 1, and impurities are trapped in the interior of the storage bin 501, and then the solenoid valve in the connecting pipe 503 is opened, so that the impurities pass through the connecting pipe 503 and enter the interior of the mounting ring 3 and are discharged through the liquid outlet 4;

[0038] At the same time, the servo motor 8 is started, and the servo motor 8 drives the transmission shaft 9 to rotate. The transmission shaft 9 drives the push rod 11 on the outer wall of the rotating shaft 10 to fit the outer wall of the placement bin 501 and push the placement bin 501 to rotate. The placement bin 501 squeezes the flat scroll spring 506. When the flat scroll spring 506 overcomes the spring at the connection position between the rotating shaft 10 and the transmission shaft 9, the flat scroll spring 506 drives the placement bin 501 to reset, so that the placement bin 501 is reset and vibrates. The vibration is transmitted to the internal automotive urea solution, causing it to shake.

[0039] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
