Description

Technical Field

[0001] The utility model relates to the technical field of vehicle urea, in particular to integrated storage and filling equipment for vehicle urea solution. Background Art

[0002] Automotive urea is a high-purity urea solution developed in recent years and suitable for SCR systems (selective catalytic reduction systems). In order to facilitate the replenishment and use of urea solution, automotive urea is generally stored in integrated storage and filling equipment so that it can be used conveniently.

[0003] In actual use, the integrated storage and filling equipment in the prior art generally installs heating elements, stirring rods, temperature sensors, etc. inside the tank to prevent the automotive urea from crystallizing when the temperature is low and the urea is left stationary for a long time. When filling is required, the heating element is started and the stirring rod is turned. When the temperature inside the tank reaches the required temperature, the urea can be filled into the vehicle.

[0004] However, in actual use, the crystals will adhere to the inner wall of the tank, making it impossible for the stirring rod to melt them quickly. As a result, when the temperature inside the tank reaches a certain level, some crystals will still not be dissolved, thereby reducing the urea concentration in the urea solution. At this time, adding automotive urea into the car will cause the SCR system to be unable to provide enough urea for effective NOx conversion, resulting in emission levels exceeding regulatory requirements.

[0022] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figures 1 to 6 The utility model provides a technical solution: an integrated storage and filling device for automotive urea solution, comprising a body 1, a stirring rod 2 is installed inside the body 1, and four snap rings 5 ​​are clamped on the outside of the stirring rod 2, and the snap rings 5 ​​on the upper and lower sides are symmetrically distributed, so that the stirring rod 2 can stably drive the snap ring 5 to rotate, and the left and right side snap rings 5 ​​are fixedly connected to the separated sides with connecting blocks 7, and the connecting block 7 can be rotated by moving the snap ring 5, and the connecting block 7 is fixedly connected to the side of the connecting block 7 away from the clamping block 6, and the inside of the placing block 8 is slidably connected with a plurality of sliders 9, and the placing block 8 has a limiting effect on the internal sliders 9, and the plurality of sliders 9 are evenly distributed, and a cleaning brush 10 is fixedly connected to one end of the slider 9 away from the placing block 8, so that the cleaning brush 10 is subjected to a relatively uniform force, and the outside of the cleaning brush 10 is in contact with the inner wall of the body 1, so that the cleaning brush 10 can stably clean the inner wall of the body 1, and the cleaning brushes 10 on the left and right sides are symmetrically distributed.

[0025] When the stirring rod 2 is rotating, the stirring rod 2 can drive the clamping ring 5 to rotate, so that the clamping ring 5 can drive the connecting block 7 to rotate, and then the connecting block 7 can drive the slider 9 to rotate through the placement block 8, so that the slider 9 can drive the cleaning brush 10 to clean the inner wall of the body 1. Since centrifugal force is generated when the stirring rod 2 rotates, the cleaning brush 10 can fit with the inner wall of the body 1, so that the crystals on the inner wall of the body 1 can be scraped off into the urea solution.

[0026] Embodiment 2

[0027] On the basis of Example 1, in order to achieve an increased cleaning effect of the cleaning brush 10, an installation groove 11 is opened inside the placement block 8, and a rubber block 12 is fixedly connected to the inner wall of the installation groove 11. The multiple rubber blocks 12 are composed of a "C"-shaped block and a "V"-shaped block. By connecting the larger angle of the "V"-shaped block with the inner bend of the "C"-shaped block, the rubber block 12 will not be easily squeezed, and then when the rubber block 12 makes a reset movement, the rubber block 12 can generate a larger reaction force. The side of the rubber block 12 close to the slider 9 is fixedly connected to a push plate 13, so that the rubber block 12 and the push plate 13 can push each other, and the outer part of the push plate 13 is slidably connected to the inside of the installation groove 11. The installation groove 11 limits the internal push plate 13, so that the push plate 13 will not deviate when moving.

[0028] When installing the cleaning brush 10, by pushing the cleaning brush 10 towards the direction close to the rubber block 12, the cleaning brush 10 can push the push plate 13 through the slider 9 to squeeze the rubber block 12 to cause deformation. Then, when the rubber block 12 makes a reset movement, the rubber block 12 can push the slider 9 to move outward through the push plate 13, so that the slider 9 can push the cleaning brush 10 to fit tightly against the inner wall of the machine body 1. At this time, the cleaning brush 10 is used in conjunction with the centrifugal force when the stirring rod 2 rotates, so that the cleaning brush 10 can clean the inner wall of the machine body 1.

[0029] Embodiment 3

[0030] On the basis of Example 2, in order to facilitate the installation of the cleaning brush 10, four placement grooves 3 are opened on the outside of the stirring rod 2, and the clamping ring 5 is clamped in the inside of the placement groove 3. The clamping ring 5 is a two-stage design and is made of polypropylene, so that the clamping ring 5 can utilize elastic potential energy to clamp in the inside of the placement groove 3. A plurality of clamping grooves 4 are opened in the inside of the placement groove 3. A plurality of clamping blocks 6 are fixedly connected to the inside of the clamping ring 5, and a plurality of protrusions are fixedly connected to the outside of the clamping block 6. The protrusions are made of rubber, and the clamping blocks 6 match the clamping grooves 4. The plurality of clamping blocks 6 are distributed in a ring shape, and the clamping blocks 6 fit in the inside of the clamping grooves 4. By utilizing the capacity of the clamping blocks 6, the clamping ring 5 and the placement groove 3 are more stably clamped, making the cleaning brush 10 safer to use.

[0031] When it is necessary to install the placement block 8 on the stirring rod 2, the snap ring 5 is opened and mounted on the placement groove 3. When the clamping block 6 is aligned with the clamping groove 4, the snap ring 5 is loosened, so that the snap ring 5 can be reset, and then the snap ring 5 can be clamped on the placement groove 3. At this time, the clamping block 6 can enter the interior of the clamping groove 4. During this process, the clamping block 6 is squeezed and deformed. When the clamping block 6 completely enters the interior of the clamping groove 4, the clamping block 6 will be reset, so that the clamping groove 4 can be completely filled, making the clamping connection between the snap ring 5 and the placement groove 3 more stable, and thus the placement block 8 will not be cleaned and detached when the stirring rod 2 rotates, so that the cleaning stability of the cleaning brush 10 on the machine body 1 is higher, and the use safety is higher.

[0032] In actual use, when the stirring rod 2 is rotating, the stirring rod 2 can drive the snap ring 5 to rotate, so that the snap ring 5 can drive the connecting block 7 to rotate, and then the connecting block 7 can drive the slider 9 to rotate through the placement block 8. At this time, when the rubber block 12 makes a reset movement, the rubber block 12 can push the slider 9 to move outward through the push plate 13, so that the slider 9 can push the cleaning brush 10 to fit tightly with the inner wall of the body 1, so that the slider 9 can drive the cleaning brush 10 to clean the inner wall of the body 1, and make the cleaning quality higher, and then the crystals can be dissolved more quickly, so that the urea solution will not be reduced, and then when it is filled into the interior of the vehicle, it will not affect the vehicle's emissions.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
