[0025] Example

[0026] like Figures 1-3 As shown, one embodiment of this utility model discloses a production device for automotive urea solution, including a processing tank 1.

[0032] Function: Used to add solid urea into processing tank 1. Sealing plate 4 can seal when no material is being fed in, preventing impurities from entering and urea from evaporating.

[0033] The sealing plate 4 slides onto the solid inlet 3.

[0034] Function: Seals solid inlet 3, is easy to operate, and allows for flexible control of the opening and closing of solid inlet 3.

[0035] The liquid outlet pipe 5 is located on one side of the processing tank 1, with one end connected to a flexible hose and the other end equipped with a valve.

[0036] Function: Used to discharge the processed vehicle urea solution from the processing tank 1, the hose reserves a shock absorption space, and the valve controls the discharge.

[0037] The sealing door 6 is hinged on one side of the processing tank 1.

[0038] Function: Used to clean the inside of the processing tank 1, facilitating opening for maintenance and cleaning.

[0039] Shock absorption device, upper swivel 7, spring column 8, lower swivel 9

[0040] The upper swivel 7 is fixedly connected to the bottom of the processing tank 1, the spring column 8 is rotatably connected to the upper swivel 7, the bottom of the spring column 8 is rotatably connected to the lower swivel 9, and the lower swivel 9 is fixedly connected to the supporting leg 10, which is arranged in a triangular shape at the bottom of the processing tank 1.

[0041] Function: To reduce the vibration of the processing tank 1 during operation, protect the equipment, and improve production stability.

[0042] The supporting leg 10, to which the lower swivel 9 is fixedly connected, is provided with a flange hole.

[0043] Function: To support the entire processing tank 1 and related devices, and the flange hole can be used to fix and install equipment.

[0044] The servo motor 11 is installed at the bottom of the processing tank 1, and the output end is fixedly connected to the rotating shaft 12 inside the processing tank 1.

[0045] Function: To provide power for the stirring device and drive the rotating shaft 12 to rotate.

[0046] The rotating shaft 12 is fixedly connected to the output end of the servo motor 11 and is inside the processing tank 1.

[0047] Function: To rotate under the drive of the servo motor 11, driving the stirring blades 13 and the rotating blades 14 to rotate.

[0048] The stirring blades 13 are fixedly connected to the rotating shaft 12.

[0049] Function: To stir the raw materials in the processing tank 1 as the rotating shaft 12 rotates, promoting the dissolution and mixing of urea.

[0050] The rotating blades 14 are connected between the stirring blades 13, are arranged obliquely on the stirring blades 13, and have a blade structure at one end.

[0051] Function: To enhance the stirring effect, the blade structure helps to cut and disperse solid urea, making the mixing more uniform.

[0052] The working principle of the vehicle urea solution production device is as follows: first, solid urea is added to the processing tank 1 through the solid inlet 3, and the sealing plate 4 can be sealed after addition to prevent impurities from entering and urea from volatilizing. The liquid raw material enters the processing tank 1 through the liquid inlet pipe 2, and the valve can control the liquid flow. Then, the servo motor 11 installed at the bottom of the processing tank 1 is started, and its output end drives the rotating shaft 12 to rotate, and the stirring blades 13 fixed on the rotating shaft 12 and the rotating plates 14 connected between the stirring blades 13 also rotate. The inclined arrangement and blade structure of the rotating plates 14 help to enhance the cutting and dispersing effect of the solid urea, so that the urea is fully dissolved and mixed in the liquid to obtain uniform vehicle urea solution. After the processing is completed, the product is discharged through the liquid outlet pipe 5, and the valve controls the discharging process. During the entire process, the shock absorber at the bottom of the processing tank 1, the upper rotating seat 7, the spring column 8, and the lower rotating seat 9 can reduce the vibration generated during the operation of the equipment, protect the equipment and improve the production stability, the sealing door 6 can be used for periodic cleaning of the inside of the processing tank 1, and the supporting legs 10 are used to support the entire device, and the flange holes can be used for fixed installation.

[0053] As shown in Figure 1 some embodiments, the processing tank 1 has a semi-circular arc plus rectangular structure; the semi-circular arc structure can better withstand internal pressure. During production, especially in the case of stirring and temperature changes, a certain pressure will be generated in the tank, and the semi-circular arc structure can uniformly disperse the pressure, reduce stress concentration, improve the overall structural stability of the processing tank 1, and prolong its service life.

[0054] In some embodiments, one end of the liquid inlet pipe 2 and the liquid outlet pipe 5 is connected to a hose, which is used to reserve a shock absorption space, and the other end of the liquid inlet pipe 2 and the liquid outlet pipe 5 is provided with a valve; during the operation of the processing tank 1, vibration will be generated due to the operation of the servo motor 11 and the stirring action of the stirring blades 13. If the liquid inlet pipe 2 and the liquid outlet pipe 5 are rigidly connected, the vibration may be transmitted to the pipeline system, causing problems such as loosening of the pipeline connection, damage to the seal, and even rupture of the pipeline. The connection of the hose at one end can play a buffering role, absorbing the displacement generated by the vibration of the processing tank 1, effectively protecting the integrity of the pipeline system, ensuring the normal transportation of the liquid, and at the same time reducing the risk of leakage caused by pipeline problems, ensuring the safety and stability of production.

[0055] As shown in Figure 1 some embodiments, the shock absorber is three, arranged in a triangular shape at the bottom of the processing tank 1; the triangle is a stable geometric structure. When the three shock absorbers are arranged in a triangular shape at the bottom of the processing tank 1, they can provide stable support and shock absorption effect.

[0056] As shown in Figure 1As shown in the drawings, in some embodiments, the leg 10 is provided with a flange hole; it is convenient to install and fix the equipment. Through the flange hole, the whole production device can be firmly installed on the ground or other support structure by using bolts and other connecting parts.

[0057] As Figure 3 As shown in the drawings, in some embodiments, the rotating blade 14 is inclined on the stirring blade 13, and one end of the rotating blade 14 is a blade structure; the blade structure helps to cut and disperse solid urea particles. During stirring, the blade end can more easily cut into larger urea particles, breaking them into smaller particles, increasing the contact area of urea particles with liquid, accelerating the dissolution speed of urea, further improving the mixing effect, and ensuring that the quality of the produced vehicle urea solution meets the standard.

[0058] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can be modified to the technical solutions recorded in the foregoing embodiments, or to the equivalent replacement of some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
