Description

Technical Field

[0001] The utility model belongs to the technical field of filling equipment, in particular to a vehicle urea buffer pressure filling device. Background Art

[0002] The CR solution has obvious advantages in the exhaust emission treatment system of National IV diesel vehicles, and automotive urea is a necessary additive for the SCR solution. As the National IV emission standard for diesel vehicles is gradually implemented in various cities, the SCR system includes a urea tank (loaded with diesel exhaust treatment fluid) and an SCR catalytic reaction tank. The operation process of the SCR system is: when nitrogen oxides are found in the exhaust pipe, the urea tank automatically sprays out diesel exhaust treatment fluid, and the diesel exhaust treatment fluid and nitrogen oxides undergo an oxidation-reduction reaction in the SCR catalytic reaction tank to generate pollution-free nitrogen and water vapor for discharge. If the diesel exhaust treatment fluid is not loaded, or the purity is insufficient, or the quality is inferior, the vehicle engine will automatically slow down. At the same time, inferior quality diesel exhaust treatment fluid will contaminate the catalyst in the SCR catalytic reaction tank, causing serious consequences;

[0003] The automotive urea buffer and pressurized filling device is a system designed specifically for automotive urea, involving multiple processes including urea production, pressurization, buffering, and filling. For pressurization and buffering, the device is equipped with primary and secondary booster pumps to address power shortages. The buffer chamber also reduces fluctuations in the outflow of ultrapure water, improving production efficiency. Filling, a key component of the device, includes a vehicle urea filler, capable of fully or semi-automatically completing urea filling operations, improving efficiency and accuracy.

[0004] After searching, the application (publication) number is: CN216687439U, which discloses: a vehicle urea filling device, "including a concave conveying frame, two conveying rollers are rotatably connected at both ends of the concave conveying frame along the length direction, and a conveyor belt is arranged and wound between the two conveying rollers, a mixing box is welded at the center of the outer wall of the concave conveying frame through a bracket, the top of the mixing box is connected to a liquid injection pipe through a hose, a slider is welded on the outer wall of the liquid injection pipe, and the slider is slidably connected to the slide groove provided on the bracket, an electric push rod is bolted to the bottom of the mixing box, and the bottom end of the electric push rod is fixed to the slider, and an electromagnetic valve, a flow meter and an infrared sensor are provided on the liquid injection pipe" and other technical features, with "a high degree of automation, which can realize assembly line operation, greatly improve its filling efficiency, reduce labor input, and the user can automatically set the filling capacity through the touch screen" and other technical effects;

[0005] However, in order to ensure the clamping stability of the filling bottle during filling, the device needs to move the limit cover downward a long distance, and the up and down reciprocating stroke is long, which affects production efficiency. In addition, in order to ensure that the limit cover is completely consistent with the filling bottle, the filling bottle must be stably and vertically pressed on the cylindrical rubber seat, and the rubber seat needs to fit the filling bottle tightly to ensure stability. This requires very high precision in the placement, docking, and filling processes, and the device cannot play a correction function. Manual placement, especially when tired, can easily cause the filling bottle to not fit completely with the cylindrical rubber seat. When the electric push rod moves downward, the limit cover and the filling bottle will scratch and collide, posing certain safety hazards.

[0006] In order to solve the above problems, the present application proposes a vehicle urea buffer pressurized filling device. Utility Model Content

[0010] Furthermore, the right-angle plates and the limit plates are two symmetrically distributed groups, the two limit plates are parallel to the moving path of the rubber seat driven by the conveyor belt, and the distance between the two limit plates is consistent with the outer diameter of the filling bottle body.

[0011] Furthermore, an arc-shaped splint is hinged on the outer side of the limit plate, and the arc-shaped splint close to the hinged end is also coaxially fixed to the original first bevel gear. Both limit plates are provided with an arc-shaped splint, and the two arc-shaped splints are distributed in a circle.

[0012] Furthermore, a second bevel gear is rotatably connected to the outer side of the limiting plate, and the second bevel gear is vertically distributed and meshed with the first bevel gear.

[0015] Furthermore, the arc-shaped clamping plate moves downward through the electric push rod to drive the toothed plate to mesh with the driving gear and rotates inward under the meshing of the second bevel gear and the first bevel gear to limit the filling bottle.

[0016] The utility model has the following beneficial effects:

[0017] The utility model can guide the front and rear positions of the filling bottle by arranging the guide plate and the limiting plate, and then limit the two sides of the filling bottle by two arc-shaped clamping plates rotating from the side, so as to ensure that the filling bottle and the rubber seat are completely perpendicular. Then, after the pressing plate is pressed down, the filling bottle and the rubber seat can be axially pressed together. By limiting the filling bottle from the front, back, left, right, top and bottom of the filling bottle at the same time in the above manner, the stability of the filling bottle during filling can be effectively guaranteed, and the impact of rigid force can be avoided.

[0018] The above-mentioned front and rear positioning can be carried out during the movement of the rubber seat driven by the conveyor belt, and the left and right and up and down positioning can be carried out during the downward movement of the electric push rod. At the same time, after the electric push rod moves downward, it also drives the liquid injection tube to connect with the bottle mouth of the filling bottle, which has the advantages of high structural coordination, tight coordination and convenient use.

[0030] See also Figure 1-5 As shown, the utility model is a vehicle-used urea buffer pressurized filling device, comprising a frame 1, a rotating conveyor belt 2 is provided on the frame 1, a rubber seat 3 is installed on the outside of the conveyor belt 2, a mixing box 4 is also installed on the frame 1, a liquid injection pipe 5 is provided at the lower end of the mixing box 4, a hose 6 is provided between the mixing box 4 and the liquid injection pipe 5, a lifting plate 7 is fixedly provided on the liquid injection pipe 5, an electric push rod 8 is provided between the lifting plate 7 and the bottom of the mixing box 4, a right-angle plate 9 is also fixedly provided at the bottom of the mixing box 4, a limit plate 10 is fixed at the lower end of the right-angle plate 9, and a guide plate 11 is provided at the end of the limit plate 10.

[0031] Among them, the right-angle plate 9 and the limit plate 10 are two symmetrically distributed groups. The two limit plates 10 are parallel to the moving path of the rubber seat 3 driven by the conveyor belt 2, and the distance between the two limit plates 10 is consistent with the outer diameter of the bottle body of the filling bottle. In this embodiment, the guide plate 11 can guide the filling bottle before it enters the limit plate 10, and the filling bottle is positioned front and back through the limit plate 10.

[0032] Among them, the outer side of the limit plate 10 is hinged with an arc-shaped splint 12, and the arc-shaped splint 12 is coaxially fixed to the original first bevel gear 13 near the hinge end. The two limit plates 10 are provided with an arc-shaped splint 12, and the two arc-shaped splints 12 are distributed circumferentially. In this embodiment, Figure 3 The two arc-shaped clamping plates 12 shown are in the open state, which does not affect the movement of the conveyor belt 2 to drive the filling bottles. Figure 4 The figure shows the state where the arc-shaped clamping plate 12 limits the filling bottle. At this time, the filling bottle is completely positioned to ensure the stability of the filling bottle during filling.

[0033] Among them, the outer side of the limiting plate 10 is rotatably connected to the second bevel gear 14, and the second bevel gear 14 is vertically distributed and meshed with the first bevel gear 13. In this embodiment, the power direction of the driving gear 15 is changed by the first bevel gear 13 and the second bevel gear 14, and then transmitted to the arcuate splint 12 and forms a rotational force, so that the arcuate splint 12 can move flexibly on the moving path of the filling bottle.

[0034] Among them, a driving gear 15 is fixed to one end of the second bevel gear 14, a transfer rod 16 is fixed to the lower end of the lifting plate 7, and a toothed plate 17 is fixed to one side of the lower end of the transfer rod 16. The toothed plate 17 is meshed and connected with the driving gear 15, and the toothed plate 17 also slides through the bracket on which the second bevel gear 14 and the driving gear 15 are installed. In this embodiment, through the meshing of the toothed plate 17 and the driving gear 15, the downward moving force of the electric push rod 8 can be simultaneously formed into a rotational force and transmitted to the arc-shaped clamping plate 12, so as to realize simultaneous downward pressure and rotation, and finally the filling bottle is stably limited during filling.

[0035] Among them, a pressure plate 18 is fixed to the other side of the lower end of the transfer rod 16. The pressure plate 18 is located on the inner side of the right-angle plate 9 and directly above the filling bottle. In this embodiment, the pressure plate 18 presses the filling bottle from top to bottom on the rubber seat 3 through the downward movement of the electric push rod 8, thereby avoiding the impact force during filling causing the filling bottle to tilt.

[0036] Among them, the arc-shaped splint 12 drives the toothed plate 17 to mesh with the driving gear 15 after the electric push rod 8 moves downward, and rotates inward under the engagement of the second bevel gear 14 and the first bevel gear 13 to limit the filling bottle. In this embodiment, after the electric push rod 8 moves downward, it can drive the arc-shaped splint 12 to fill the bottle, and at the same time drive the liquid injection tube 5 to dock with the bottle mouth of the filling bottle. The two are carried out simultaneously, which improves the structural linkage and convenience of use.

[0037] It can be understood that by setting the limit plate, guide plate, arc splint and pressure plate, the filling bottle can be positioned from different directions, and at the same time it has a correction effect. When the filling bottle is positioned, the filling tube is also docked with the bottle mouth, and the filling work can be carried out directly. Through the above scheme, the positioning stability and effect of the filling bottle are improved, and the filling reliability can be guaranteed while having better adaptability. The stroke of the electric push rod is also greatly shortened, and at the same time the stability of the filling bottle can be guaranteed, further improving the filling efficiency.

[0038] A specific application of this embodiment is as follows: during filling, the filling bottle is placed on the rubber seat 3, conveyed by the conveyor belt 2 to the bottom of the liquid injection pipe 5 and then stopped. The filling bottle is limited by the guide plate 11 and the limit plate 10 when entering the bottom of the liquid injection pipe 5, and then the electric push rod 8 drives the lifting plate 7 to move down. After the lifting plate 7 moves down, it drives the liquid injection pipe 5 to move down and dock with the bottle mouth of the filling bottle. After the lifting plate 7 moves down, it also drives the transfer rod 16 to move down. The pressure plate 18 on the transfer rod 16 presses the mixing box 4 downward between the mixing box 4, and the transfer rod 16 After moving downward, it drives the tooth plate 17 to move downward, and the tooth plate 17 is meshed with the driving gear 15. After the driving gear 15 rotates, the second bevel gear 14 is meshed with the first bevel gear 13, and drives the arc splint 12 to rotate until the two arc splints 12 limit the two sides of the filling bottle. The electric push rod 8 stops, and then the filling work is carried out. After the rear shift is completed, the electric push rod 8 moves upward, the arc splint 12 is disengaged from the limit of the filling bottle, and the pressure plate 18 is disengaged from the pressure on the filling bottle. The conveyor belt 2 is started again to drive the filling bottle to continue moving.
