Description

Technical Field

[0001] This utility model belongs to the field of automotive urea technology, specifically relating to an automotive urea solution stirring device. Background Technology

[0002] Automotive urea is a liquid specifically used for treating diesel vehicle exhaust; it is also known as diesel exhaust fluid, automotive environmental urea, or automotive urea. Its main components are urea and deionized water, and it is typically composed of high-purity urea and deionized water.

[0003] Existing automotive urea solution mixing equipment mainly relies on a single stirring rod to achieve mixing and stirring of urea solution. However, a single stirring rod has limitations in achieving uniformity, speed and efficiency in stirring urea solution, which can lead to inconsistencies in the concentration distribution of urea solution and thus adversely affect the effectiveness of urea solution. Therefore, an automotive urea solution mixing device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle urea solution stirring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle urea solution stirring device, comprising a stirring drum, an internal stirring device, a support base, a servo motor fixedly connected to the top of the support base, a rotating connecting rod fixedly connected to the output end of the servo motor, a bearing rotatably connected to the surface of the rotating connecting rod, three fixed connecting rods fixedly connected to the surface of the bearing, a helical propulsion blade fixedly connected to the surface of the rotating connecting rod, four turbine blades fixedly connected to the surface of the rotating connecting rod, two mounting connecting rods fixedly connected to the surface of the rotating connecting rod, mounting plates fixedly connected to one end of each of the two mounting connecting rods, multiple inclined blades fixedly connected to one side surface of each of the two mounting plates, and bidirectional scrapers fixedly connected to the other side surface of each of the two mounting plates.

[0006] By setting up the above structure, when it is necessary to ensure the mixing effect of the urea solution, the servo motor is started and the rotating linkage drives the spiral propeller, four sets of turbine blades and tilting blades to stir the urea solution. When the spiral propeller rotates, it can generate a strong axial thrust on the urea solution at the bottom, causing the urea solution at the bottom to rise rapidly. When the four sets of turbine blades rotate, they can generate strong radial flow and shear force, which can fully shear and disperse the urea solution pushed from the bottom, promoting full contact and mixing of the components in the urea solution. The rotation of the tilting blades can generate oblique flow, which can break the laminar flow state in the urea solution and increase the turbulence of the urea solution. Under the combined action of the spiral propeller, turbine blades and tilting blades, an interwoven, complex and three-dimensional stirring flow field can be formed inside the stirring drum, thereby comprehensively improving the stirring effect of the urea solution and ensuring that the solution can be mixed quickly and uniformly.

[0007] As a preferred embodiment, the surface of the stirring drum is provided with a support ring, the surface of the support ring is provided with two support legs, and the surface of the support ring is provided with a controller.

[0008] As a preferred embodiment, the surface of the mixing drum is provided with two limiting rings, the top of the mixing drum is provided with two inlets, and the bottom of the mixing drum is provided with two outlets.

[0009] As a preferred embodiment, the bottom of the support base is fixedly connected to the top of the stirring cylinder.

[0010] As a preferred embodiment, the rotating connecting rod rotates inside the support base and inside the stirring drum.

[0011] As a preferred embodiment, one end of each of the three fixed connecting rods is fixedly connected to the inner wall of the stirring cylinder.

[0012] As a preferred embodiment, the bidirectional scraper is fitted to the inner wall of the mixing drum.

[0013] By configuring a bidirectional scraper, the bidirectional scraper can effectively remove urea adhering to the inner wall of the mixing drum, thereby ensuring that the mixing concentration of the urea solution is as uniform as possible. In addition, the bidirectional scraper can also clean the inner wall of the mixing drum, preventing urea solution residue on the drum wall, thus ensuring a smooth mixing process of the urea solution and the stability of the urea solution quality.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by incorporating a servo motor, a rotating linkage, a helical propeller, a turbine blade, and an inclined blade, allows for efficient mixing of the urea solution. When the mixing effect of the urea solution needs to be ensured, the servo motor is activated, and the rotating linkage drives the helical propeller, four turbine blades, and the inclined blade to stir the urea solution. The rotating helical propeller generates a strong axial thrust on the urea solution at the bottom, causing it to rise rapidly. The rotating turbine blades generate strong radial flow and shear force, effectively shearing and dispersing the urea solution pushed from below, promoting thorough contact and mixing of the components. The rotation of the inclined blades generates oblique flow, breaking the laminar flow state of the urea solution and increasing its turbulence. The combined action of the helical propeller, turbine blades, and inclined blades creates an interwoven, complex, and three-dimensional mixing flow field inside the mixing drum, thereby comprehensively improving the mixing effect of the urea solution and ensuring rapid and uniform mixing.

[0016] This invention, by configuring a bidirectional scraper, can effectively remove urea adhering to the inner wall of the mixing drum, thereby ensuring that the mixing concentration of the urea solution is as uniform as possible. In addition, the bidirectional scraper can also clean the inner wall of the mixing drum, preventing urea solution residue on the drum wall, thus ensuring a smooth mixing process of the urea solution and the stability of the urea solution quality.

[0023] Please see Figure 1-3 This utility model provides a vehicle urea solution stirring device, including a stirring drum 1. A stirring device 8 is installed inside the stirring drum 1. The stirring device 8 includes a support base 801. A servo motor 802 is fixedly connected to the top of the support base 801. A rotating connecting rod 803 is fixedly connected to the output end of the servo motor 802. A bearing 804 is rotatably connected to the surface of the rotating connecting rod 803. Three fixed connecting rods 805 are fixedly connected to the surface of the bearing 804. A helical propeller blade 806 is fixedly connected to the surface of the rotating connecting rod 803. Four turbine blades 807 are fixedly connected to the surface of the rotating connecting rod 803. Two mounting rods 808 are fixedly connected to the surface of the rotating connecting rod 803. One end of each of the two mounting rods 808 is fixedly connected to a mounting plate 809. Multiple inclined blades 810 are fixedly connected to one side of each of the two mounting plates 809. Bidirectional scrapers 811 are fixedly connected to the other side of each of the two mounting plates 809. This is achieved by configuring a servo motor 802, rotating connecting rod 803, helical propulsion blades 806, and turbine blades... When the mixing effect of the urea solution needs to be ensured, the servo motor 802 is activated and the connecting rod 803 drives the spiral propeller 806, four sets of turbine blades 807, and the inclined blades 810 to stir the urea solution. When the spiral propeller 806 rotates, it can generate a strong axial thrust on the urea solution at the bottom, causing the urea solution at the bottom to rise rapidly. When the four sets of turbine blades 807 rotate, they can generate strong radial flow and shear force, which can effectively stir the urea solution pushed from the bottom. The urea solution undergoes thorough shearing and dispersion, promoting full contact and mixing of its components. The rotation of the tilting blade 810 generates an oblique flow, breaking the laminar flow state in the urea solution and increasing its turbulence. Under the combined action of the helical propulsion blade 806, the turbine blade 807, and the tilting blade 810, an interwoven, complex, and three-dimensional stirring flow field is formed inside the stirring drum 1, thereby comprehensively improving the stirring effect of the urea solution and ensuring that the solution can be mixed quickly and uniformly.

[0024] The surface of the mixing drum 1 is provided with a support ring 2, the surface of the support ring 2 is provided with two support legs 3, and the surface of the support ring 2 is provided with a controller 4.

[0025] The surface of the mixing drum 1 is provided with two limiting rings 5, the top of the mixing drum 1 is provided with two inlet ports 6, and the bottom of the mixing drum 1 is provided with two outlet ports 7.

[0026] The bottom of the support base 801 is fixedly connected to the top of the mixing tank 1.

[0027] The rotating connecting rod 803 rotates inside the support base 801 and inside the stirring cylinder 1.

[0028] One end of each of the three fixed connecting rods 805 is fixedly connected to the inner wall of the mixing drum 1.

[0029] The bidirectional scraper 811 is attached to the inner wall of the mixing drum 1. By configuring the bidirectional scraper 811, it can effectively remove the urea adhering to the inner wall of the mixing drum 1, thereby ensuring that the mixing concentration of the urea solution is as uniform as possible. In addition, the bidirectional scraper 811 can also clean the inner wall of the mixing drum 1 to prevent urea solution from remaining on the drum wall, thus ensuring a smooth mixing process of the urea solution and the stability of the urea solution quality.

[0030] The working principle and usage of this utility model are as follows: When it is necessary to ensure the mixing effect of the urea solution, the servo motor 802 is started to drive the rotating connecting rod 803 to rotate. When the rotating connecting rod 803 rotates, it drives the spiral propeller blade 806, the four sets of turbine blades 807, and the inclined blades 810 to stir the urea solution inside the mixing tank 1. When the spiral propeller blade 806 rotates, it generates a strong axial thrust on the urea solution at the bottom, causing the urea solution at the bottom to flow upward rapidly. When the four sets of turbine blades 807 rotate, they generate a strong radial flow and shear force, which helps to stir the urea solution from the bottom. The urea solution pushed up can be fully sheared and dispersed by the turbine blades 807. The rotation of the tilting blades 810 generates an oblique flow, which can break the laminar flow state in the urea solution. Under the stirring of three different directions generated by the helical propulsion blades 806, the four sets of turbine blades and the tilting blades 810, an interwoven, complex and three-dimensional stirring flow field can be generated inside the stirring tank 1, which comprehensively improves the stirring effect of the urea solution. In addition, the synchronously rotating bidirectional scraper 811 scrapes the inner wall of the stirring tank 1 to prevent the urea solution from remaining on the inner wall of the stirring tank 1.
