Description
Technical Field
[0001] This utility model relates to the field of filling equipment technology, specifically to a vehicle urea filling device. Background Technology
[0002] In today's transportation sector, to meet increasingly stringent exhaust emission standards, automotive urea, as an important exhaust treatment fluid, is widely used in diesel engine vehicles. It effectively reduces nitrogen oxide emissions, decreases atmospheric pollution, and plays a crucial role in improving air quality. However, existing technologies and equipment in the production and filling process of automotive urea present numerous unresolved problems.
[0003] In the mixing stage of automotive urea solution, traditional mixing equipment often suffers from uneven mixing. Some mixing devices have poorly designed mixing structures with limited mixing ranges, failing to fully mix the automotive urea raw materials. This results in uneven distribution of components in the solution, affecting the quality and performance of the urea solution. Unstable urea solutions may not fully reduce nitrogen oxide emissions during use and could even damage the vehicle's exhaust treatment system. In the filling stage, most existing filling devices cannot achieve precise quantitative filling. Some devices rely on manual control of the filling volume, which is not only inefficient but also prone to inaccurate filling amounts, leading to inconsistent product quality. Utility Model Content
[0004] The purpose of this utility model is to provide a vehicle urea filling device that solves the technical problem of unreasonable stirring structure design, limited stirring range, and inability to fully mix vehicle urea raw materials, thereby achieving full stirring and ensuring the stability of urea solution performance.

[0006] Preferably, the filling assembly includes: a metering component disposed on the top of the fixing frame; and a stirring component disposed on the back of the fixing frame.
[0007] Preferably, the metering component includes: a support frame, fixedly installed on the top of the fixed frame; and metering cylinders, equidistantly sleeved on the top of the fixed frame.
[0008] Preferably, a cylinder is fixedly installed on the top of the support frame, the telescopic end of the cylinder movably passes through the top of the support frame and extends to the bottom of the support frame, and a connecting top plate is fixedly installed thereon. Guide rods are symmetrically fixedly installed on the top of the connecting top plate, the top ends of the guide rods movably pass through the bottom of the support frame and extend to the top of the support frame, and a limit plate is fixedly installed thereon.
[0009] The cylinder extension end at the top of the support frame is fixedly connected to the connecting top plate. The extension and retraction of the cylinder can stably drive the connecting top plate to move up and down. The connecting top plate is then connected to the piston through a connecting column, thereby enabling the piston to move linearly within the metering cylinder.
[0010] Preferably, connecting columns are installed at equal intervals at the bottom of the connecting top plate, a piston is fixedly installed at the bottom end of the connecting column, the piston is movably sleeved inside the metering cylinder, an electric valve is provided at the bottom of the metering cylinder, a connecting pipe is connected to the back of the metering cylinder, and a horizontal pipe is connected to the other end of the connecting pipe.
[0011] The connecting columns and pistons at the bottom of the top plate are installed at equal intervals, corresponding one-to-one with multiple metering cylinders. This allows multiple metering cylinders to perform metering operations simultaneously, improving filling efficiency.
[0012] Preferably, the stirring component includes: a storage tank disposed on the back of the fixing frame; a feed pipe fixedly sleeved on the top of the storage tank; a motor fixedly installed on the top of the storage tank; and an insulation shell fixedly sleeved on the outer wall of the storage tank.

[0016] The stirring rods, which are equidistantly installed on the outer circumference of the stirring shaft, rotate along with the stirring shaft when the motor drives it, thus fully stirring the automotive urea raw material in the storage tank.
[0017] This utility model provides a vehicle urea filling device. It has the following beneficial effects:
[0018] (1) This utility model starts with a motor, which drives the stirring shaft to rotate. The stirring rods, which are equidistantly installed on the outer wall of the stirring shaft, rotate accordingly to stir the automotive urea raw material in the storage tank, so that the raw material is mixed evenly. The temperature sensing module on the inner wall of the storage tank monitors the temperature of the solution in the tank in real time and feeds the temperature signal back to the controller. When the temperature is lower than the set value, the controller controls the heating plate between the heat preservation shell and the storage tank to start, so as to heat the solution and keep the solution within a suitable temperature range, thus ensuring the stability of the urea solution performance.
[0019] (2) This utility model starts by pumping. The pumping pump draws a well-stirred and appropriately heated automotive urea solution from the storage tank through the pumping pipe. The solution is transported to the horizontal pipe through the discharge pipe and then flows into each metering cylinder through the connecting pipe. When the solution in the metering cylinder reaches the preset quantitative value, the pumping pump stops working. The controller controls the extension end of the cylinder to extend, driving the connecting top plate to move downward. The connecting top plate drives the piston to move downward in the metering cylinder through the connecting column. At the same time, the controller opens the electric valve at the bottom of the metering cylinder. The piston pushes out the automotive urea solution in the metering cylinder and fills it into the corresponding container through the electric valve, thus achieving the effect of quantitative filling.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0029] Example 1:
[0030] Based on the existing problems of unreasonable mixing structure design, limited mixing range, and inability to fully mix automotive urea raw materials, the preferred embodiment of the automotive urea filling device provided by this utility model is as follows: Figure 1-4 As shown: A vehicle urea filling device includes a base plate 1, a controller 2 disposed on the top of the base plate 1, a fixing frame 3 fixedly mounted on the top of the base plate 1, and a filling assembly 4 disposed on the top of the base plate 1. The filling assembly 4 includes: a metering component 41 disposed on the top of the fixing frame 3; and a stirring component 42 disposed on the back of the fixing frame 3. The metering component 41 includes: a support frame 411 fixedly mounted on the top of the fixing frame 3; and metering cylinders 416 equidistantly sleeved on the top of the fixing frame 3. A cylinder 412 is fixedly mounted on the top of the support frame 411, and the telescopic end of the cylinder 412 extends through the top of the support frame 411 and extends to the bottom of the support frame 411. A connecting top plate 413 is fixedly installed, and guide rods 414 are symmetrically fixedly installed on the top of the connecting top plate 413. The top end of the guide rods 414 moves through the bottom of the support frame 411 and extends to the top of the support frame 411. A limit plate 415 is fixedly installed thereon. Connecting columns 418 are equidistantly installed at the bottom of the connecting top plate 413. A piston 419 is fixedly installed at the bottom end of the connecting column 418. The piston 419 is movably sleeved inside the metering cylinder 416. An electric valve 417 is provided at the bottom of the metering cylinder 416. A connecting pipe 4111 is connected to the back of the metering cylinder 416. A horizontal pipe 4112 is connected to the other end of the connecting pipe 4111.
[0031] Furthermore, in this embodiment, the pump 4212 is activated, and the pump 4212 draws a well-stirred and appropriately heated automotive urea solution from the storage tank 421 through the extraction pipe 4211. The solution is then transported to the horizontal pipe 4112 through the discharge pipe 4213, and then flows into each metering cylinder 416 through the connecting pipe 4111. At this time, the electric valve 417 at the bottom of the metering cylinder 416 is closed, the telescopic end of the cylinder 412 is extended, the connecting top plate 413 is in a higher position, and the piston 419 at the bottom of the connecting column 418 is in a higher position inside the metering cylinder 416, providing space for the metering cylinder 416 to feed and guide the flow. Rod 414 and limiting plate 415 ensure the smooth movement of connecting top plate 413 and prevent it from deviating. When the solution in metering cylinder 416 reaches the preset quantitative value, pump 4212 stops working. Controller 2 controls the extension end of cylinder 412 to extend, driving connecting top plate 413 to move downward. Connecting top plate 413 drives piston 419 to move downward in metering cylinder 416 through connecting column 418. At the same time, controller 2 opens electric valve 417 at the bottom of metering cylinder 416. Piston 419 pushes out automotive urea solution in metering cylinder 416 and fills it into the corresponding container through electric valve 417, realizing quantitative filling.
[0032] Example 2:
[0033] Based on Embodiment 1, a preferred embodiment of the vehicle urea filling device provided by this utility model is as follows: Figure 1-4 As shown: The stirring component 42 includes: a storage tank 421, disposed on the back of the fixing frame 3; a feed pipe 422, fixedly sleeved on the top of the storage tank 421; a motor 425, fixedly installed on the top of the storage tank 421; an insulation shell 428, fixedly sleeved on the outer wall of the storage tank 421; a heating plate 429 is disposed between the insulation shell 428 and the storage tank 421; a filter plate 423 is disposed inside the feed pipe 422; a pipe cap 424 is threadedly connected to the top end of the feed pipe 422; and a stirring shaft 426 is disposed at the output end of the motor 425. The other end of 6 extends through the top of the storage tank 421 and into the interior of the storage tank 421, and is rotatably connected to the storage tank 421 via a bearing. Stirring rods 427 are equidistantly installed on the outer circumference of the stirring shaft 426. A material extraction pipe 4211 is connected to one side of the storage tank 421, and a pump 4212 is connected to the other end of the material extraction pipe 4211. A discharge pipe 4213 is connected to the output end of the pump 4212, and the other end of the discharge pipe 4213 is connected to the horizontal pipe 4112. A temperature sensing module 4214 is provided on the inner wall of the storage tank 421.
[0034] Furthermore, in this embodiment, the motor 425 is started, driving the stirring shaft 426 to rotate. The stirring shaft 426 is rotatably connected to the storage tank 421 via bearings to ensure rotational stability. The stirring rods 427, which are equidistantly installed on the outer circumference of the stirring shaft 426, rotate accordingly, stirring the automotive urea raw material in the storage tank 421 to ensure uniform mixing and improve the quality of the urea solution. The temperature sensing module 4214 on the inner wall of the storage tank 421 monitors the temperature of the solution in the tank in real time and feeds the temperature signal back to the controller 2. When the temperature is lower than the set value, the controller 2 controls the heating plate 429 between the heat preservation shell 428 and the storage tank 421 to start, heating the solution and keeping it within a suitable temperature range to ensure the stable performance of the urea solution.
[0035] In use, open the cap 424 at the top of the feed pipe 422 and add the automotive urea raw material into the storage tank 421 through the feed pipe 422. The filter plate 423 inside the feed pipe 422 will filter the raw material to remove impurities, ensuring the purity of the automotive urea raw material entering the storage tank 421. The operator starts the device through the controller 2 on the top of the base plate 1 and sets relevant parameters, such as the quantitative filling amount, stirring time, heating temperature, etc. The controller 2 controls the motor 425 to start, and the motor 425 drives the stirring shaft 426 to rotate. The stirring shaft 426 is rotatably connected to the storage tank 421 through bearings to ensure the stability of rotation. The outer circumference of the stirring shaft 426 is equidistant. The installed stirring rod 427 rotates to stir the automotive urea raw material in the storage tank 421, ensuring uniform mixing and improving the quality of the urea solution. The temperature sensing module 4214 on the inner wall of the storage tank 421 monitors the temperature of the solution in real time and feeds the temperature signal back to the controller 2. When the temperature is lower than the set value, the controller 2 activates the heating plate 429 between the insulation shell 428 and the storage tank 421 to heat the solution, maintaining it within a suitable temperature range and ensuring stable performance of the urea solution. The controller 2 also activates the pump 4212, which draws uniformly stirred and appropriately heated urea from the storage tank 421 through the extraction pipe 4211. The automotive urea solution is conveyed through the discharge pipe 4213 to the horizontal pipe 4112, and then flows into each metering cylinder 416 through the connecting pipe 4111. At this time, the electric valve 417 at the bottom of the metering cylinder 416 is closed, the telescopic end of the cylinder 412 is extended, the connecting top plate 413 is in a higher position, and the piston 419 at the bottom of the connecting column 418 is in a higher position inside the metering cylinder 416, providing space for the metering cylinder 416 to feed. The guide rod 414 and the limiting plate 415 ensure that the connecting top plate 413 moves smoothly and prevents it from deviating. When the solution in the metering cylinder 416 reaches the preset quantitative value, the pump 4212 stops working, and the controller 2 controls the cylinder 412. The telescopic end of the cylinder 412 extends, causing the connecting top plate 413 to move downward. The connecting top plate 413, through the connecting column 418, drives the piston 419 to move downward inside the metering cylinder 416. At the same time, the controller 2 opens the electric valve 417 at the bottom of the metering cylinder 416. The piston 419 pushes out the automotive urea solution in the metering cylinder 416 and fills it into the corresponding container through the electric valve 417, thus achieving metered filling. After one filling is completed, the telescopic end of the cylinder 412 extends again, causing the piston 419 to return to its original position. The electric valve 417 closes, and the pump 4212 starts again to replenish the automotive urea solution in the metering cylinder 416, entering the next metered filling cycle until all filling tasks are completed.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
