[0002] Automotive urea, also known as diesel exhaust treatment fluid, automotive urea, automotive environmentally friendly urea or diesel exhaust purification fluid, is a liquid specially used for SCR technology. Its main function is to reduce nitrogen oxide pollution in diesel exhaust. When automotive urea is produced, the dissolution of solid urea is the process of converting solid urea particles into liquid urea solution. This process is one of the key steps in the production of automotive urea because it directly affects the quality and stability of the final product.
[0003] At present, the existing solid urea has different particle sizes during the dissolution process, which often takes a long time, affecting the dissolution efficiency and is not conducive to the efficient production and use of automotive urea.
[0004] In order to solve the above problems, the present application proposes a solid dissolution and filtration device for the production of automotive urea. Utility Model Content
[0005] The purpose of the utility model is to provide a solid dissolution and filtering device for producing automotive urea, which solves the problems raised in the above-mentioned background technology.
[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0007] The utility model discloses a solid dissolution and filtering device for producing automotive urea, comprising: a dissolving tank and a feeding cylinder above the dissolving tank, wherein a rotating motor is installed at the upper end of the feeding cylinder and the feeding pipeline is connected to the side adjacent to the upper end; a secondary cylinder is provided at the lower end of the feeding cylinder, and a secondary roller is rotatably installed inside the secondary cylinder, a rolling roller is provided inside the feeding cylinder and is connected to the rotating motor through a connecting shaft inside the secondary cylinder, and the solid urea is rolled and crushed when the connecting shaft and the secondary roller rotate to increase the dissolution rate; a bulking plate is provided inside the upper end of the dissolving tank for evenly scattering the crushed solid urea to prevent accumulation, and a filter plate is provided at the lower end of the bulking plate, and the filter plate is moved by a rotating frame provided on the outer side of the lower end of the connecting shaft to prevent impurities from clogging the mesh.
[0008] Furthermore, a guide platform and an outer ring frame are respectively provided on the inner side and the outer side of the filter plate to prevent the material from accumulating in the outer area and affecting the dissolution operation.
[0009] Furthermore, a connecting rod is provided at the upper end of the outer ring frame and connected to the outer side of the bulk plate to form support and fixation, and the connecting rod is evenly distributed circumferentially on the outer side of the bulk plate.
[0010] Furthermore, a positioning brush is provided below the rotating frame, which scrapes the surface of the filter plate when the rotating frame rotates to drive the impurities to move and prevent the impurities from gathering and accumulating in one place.
[0011] Furthermore, the lower end of the filter plate is provided with a shaft seat for rotatably mounting the lower end of the connecting shaft, which forms a supporting effect while preventing the filter plate from swinging due to being too far away from the rotating motor.
[0012] Furthermore, a spiral groove is provided on the outer side of the rolling roller to promote the circulation of materials, and a guide slope is provided on the upper end of the auxiliary roller to gather the materials between the rolling roller and the auxiliary roller.
[0013] Furthermore, a transmission gear is provided at the upper end of the auxiliary roller and is engaged with a transmission gear ring frame at the upper end of the auxiliary cylinder, so that adjacent transmission gears rotate simultaneously to perform rolling operations.
[0014] The utility model has the following beneficial effects:
[0015] When adding solid urea, the utility model first enters between the rolling roller and the guide slope, and then is rolled by the simultaneous rotation of the two rollers, so that large particles of solid urea are crushed to promote the subsequent dissolution efficiency. Compared with the existing treatment method, the production efficiency of automotive urea can be greatly improved, and the dissolution time inside the filter mechanism can be reduced to prevent excessive accumulation and blockage.
[0016] When the crushed solid urea is discharged, it is first dispersed by the dispersing plate to be evenly scattered in the circumferential direction to prevent accumulation from affecting the dissolution rate. At the same time, the crushing operation can also drive the rotating frame to rotate through the connecting frame shaft, and use the positioning brush to clean the impurities on the surface of the filter plate to prevent the impurities from clogging the mesh holes, thereby ensuring the stable progress of the subsequent dissolution operation.
[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figure 1-5 As shown, the utility model is a solid dissolution and filtration device for the production of automotive urea, comprising: a dissolution tank 1 and a feeding cylinder 2 above it, a rotating motor is installed on the upper end of the feeding cylinder 2 and a feeding pipeline is connected to the side adjacent to the upper end;
[0029] A secondary cylinder 3 is provided at the lower end of the feeding cylinder 2, and a secondary roller 7 is rotatably installed inside the secondary cylinder 3. A rolling roller 6 is provided inside the feeding cylinder 2 and is connected to a rotating motor through a connecting shaft 10 inside the secondary cylinder 3. When the connecting shaft 10 and the secondary roller 7 rotate, the solid urea is rolled to crush it to increase the dissolution rate.
[0030] A bulk plate 4 is provided inside the upper end of the dissolving tank 1 to evenly scatter the crushed solid urea to prevent accumulation. A filter plate 5 is provided at the lower end of the bulk plate 4. The filter plate 5 is moved by a rotating frame 8 provided on the outer side of the lower end of the connecting shaft 10 to prevent impurities from clogging the mesh.
[0031] The present embodiment provides a solid urea dissolution and filtration mechanism with a high dissolution rate. The solid urea can be crushed and pulverized immediately by the cooperation of the rolling roller 6 and the auxiliary roller 7, and evenly dispersed through the bulk plate 4 for discharge to prevent the accumulation of materials of different sizes. While ensuring the dissolution rate, the filter plate 5 can be moved in real time by the rotating frame 8 to dredge its mesh to prevent impurities from accumulating in the mesh and causing blockage.
[0032] The inner and outer sides of the filter plate 5 are provided with a guide platform 13 and an outer ring frame 15 respectively, which are used to prevent the material from accumulating in the outer area and affecting the dissolution operation, and at the same time avoid the material from entering the gap between adjacent components and affecting the use effect.
[0033] The upper end of the outer ring frame 15 is provided with a connecting rod 9 connected to the outer side of the bulk plate 4. The connecting rod 9 is evenly distributed circumferentially on the outer side of the bulk plate 4 to form a stable supporting effect.
[0034] Among them, a positioning brush 11 is provided under the rotating frame 8. When the rotating frame 8 rotates, it scrapes the surface of the filter plate 5 to drive the impurities to move, prevent the impurities from gathering and accumulating in one place, and ensure the normal performance of the filter plate 5. Secondly, the movement of impurities can also facilitate subsequent centralized cleaning and use.
[0035] The lower end of the filter plate 5 is provided with a shaft seat 12 for rotatably mounting the lower end of the connecting shaft 10, which not only forms a supporting effect but also positions the lower end of the connecting shaft 10 to prevent the lower end from swinging due to being too far away from the rotating motor.

[0038] It can be understood that the utility model can crush the added materials and scatter them evenly, preventing them from being uneven in size and avoiding aggregation and accumulation when feeding, so as to ensure an efficient dissolution rate. Secondly, impurities can be cleaned in real time during the dissolution process to prevent impurities from clogging the mesh for a long time and affecting the use effect of the filtering mechanism.
[0039] A specific application of the operation process of this embodiment is as follows: when in use, firstly, the solid urea is rolled by the rotation of the rolling roller 6 and the auxiliary roller 7 to crush the large particles therein, and then dispersed by the bulk plate 4, and then evenly scattered on the surface of the filter plate 5 for dissolution. The crushing process can effectively prevent the solid urea from being too large to increase the dissolution rate. Secondly, the bulk plate 4 can prevent urea from accumulating in the center position and affecting the normal dissolution operation. Finally, during the crushing operation, the rotating frame 8 can be driven to rotate via the connecting frame shaft 10, and then the positioning brush 11 below it can be used to clean the impurities on the surface of the filter plate 5 to prevent a large amount of impurities from accumulating and clogging the mesh.
