Description

Technical Field

[0001] This utility model relates to the field of automotive urea processing technology, specifically to an automotive urea filling device with a positioning component. Background Technology

[0002] Urea is a nitrogen-containing organic compound that is widely used in industry, agriculture and transportation. Among them, automotive urea is used as a reducing agent in the selective catalytic reduction system of diesel vehicles and is a key consumable for diesel vehicles to achieve compliant emissions.

[0003] With the continuous upgrading of environmental protection requirements, the market demand for automotive urea continues to grow. In its processing and production, the filling process is the core process connecting the production end and the user end, which requires the precise transfer of the produced automotive urea from the storage tank to a special storage container.

[0004] However, when filling urea for vehicles, conveyor belts are often used to transport containers in batches. During the transport process, the containers are prone to positional shifts due to conveyor belt vibration and initial placement deviations. This shift can cause the filling head to fail to align precisely with the container opening, leading to leakage of urea. Leaking urea not only wastes raw materials but also contaminates the equipment. Therefore, there is an urgent need to develop a vehicle urea filling device with positioning components to solve these practical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vehicle urea filling device with a positioning component, which solves the problem that the position of the container to be filled is easily offset due to conveyor belt vibration and initial placement deviation during vehicle urea filling and transportation. This offset makes it impossible for the filling head to be accurately aligned with the container opening, resulting in urea leakage. Leakage not only directly wastes raw materials but also contaminates the device.

[0006] To achieve the above objectives, this utility model provides a vehicle urea filling device with a positioning component, comprising a bracket, a filling component, and a positioning mechanism.

[0007] The filling assembly includes a mounting base for providing an installation position, an electric rod for driving the mounting base to move vertically, a solenoid valve tube for connecting to an external urea supply device and conveying automotive urea, and a filling head for filling the automotive urea inside the solenoid valve tube.

[0008] The positioning mechanism includes shaft frames disposed on both sides of the top of the mounting base. A movable frame is rotatably mounted inside the shaft frames. A slope plate with a V-shaped cross-section is fixedly connected to the bottom end of the movable frame. A ball bearing for guiding the filling container is disposed on one side of the slope plate, and the ball bearing is equidistantly rotatably mounted on one side of the slope plate. A limit groove is also disposed on one side of the slope plate, and the limit groove is located at the center position on the same side of the slope plate and the ball bearing. A drive assembly for driving the movable frame to rotate is also disposed on the top of the mounting base. Preferably, the drive assembly includes a housing disposed on both sides of the top of the mounting base. A first motor is fixedly connected inside the housing. The output end of the first motor passes through one side of the housing and is fixedly connected to one end of a support rod. The other end of the support rod passes through one side of the shaft frame and is fixedly connected to the movable frame.

[0009] Preferably, the electric rod is fixed to one side of the top of the bracket, the output end of the electric rod passes through the top of the bracket and is fixedly connected to the top of the mounting base, a solenoid valve tube is fixedly connected to the center of the top of the mounting base, and the top end of the solenoid valve tube passes through the center of the top of the bracket, and the bottom end of the solenoid valve tube is connected to the top of the filling head for conveying the urea to be filled.

[0010] Preferably, it also includes a sealing assembly, which includes a second motor for providing a power source, a shaft for transmitting the rotational power of the second motor, a crossbar for providing an installation position, a vertically movable moving rod, a spring for elastically abutting the moving rod to reset, and a rubber sealing seat for abutting the bottom end of the filling head to achieve a seal.

[0011] Preferably, the second motor is mounted on the top of the mounting base, the output end of the second motor passes through the top of the mounting base and is fixedly connected to the top of the shaft, the top of one end of the crossbar is fixedly connected to the bottom end of the shaft, the moving rod is movably passed through the interior of one end of the crossbar, and a spring for applying elastic restoring force to the moving rod is sleeved on the outer side of the bottom end of the moving rod, and a rubber sealing seat for sealing the bottom of the filling head is fixedly connected to the top of the moving rod.

[0012] Preferably, the rubber sealing seat is made of wear-resistant rubber material to reduce frictional wear between the rubber sealing seat and the bottom of the filling head.

[0013] This invention provides a vehicle urea filling device with a positioning component. Compared with the prior art, it has the following advantages.

[0014] 1. Two sets of first motors drive the support rods to rotate, and the support rods drive the moving frame to move in an arc around the shaft frame as the axis. This causes two sets of ball bearings to contact the outside of the container. The V-shaped slope plate cooperates with the ball bearings, so that the container rotates along the surface of the slope plate against the ball bearings and moves into the limiting groove. The two sets of closed slope plates position the container inside the limiting groove, so that the container is perpendicular to the filling head, realizing the positioning filling function. This solves the problems of urea leakage, equipment contamination and urea waste caused by container position deviation during filling.

[0015] 2. The second motor drives the shaft to rotate, and the shaft drives the crossbar to move in a semi-circular shape, so that the rubber sealing seat touches the bottom of the filling head. After the rubber sealing seat is touched, the spring elastic force drives the moving rod to move down, so that the rubber sealing seat touches the center of the bottom of the filling head to seal it. This solves the problem of urea concentration reduction, nitrogen oxide reduction efficiency decrease and subsequent filling quality difference caused by the open absorption of carbon dioxide.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] First implementation method:

[0024] refer to Figure 1-5 A vehicle urea filling device with a positioning component includes a bracket 1, a filling component, and a positioning mechanism 2.

[0025] The filling assembly includes a mounting base 102 for providing an installation position, an electric rod 101 for driving the mounting base 102 to move vertically, a solenoid valve tube 103 for connecting to an external urea supply device and conveying automotive urea, and a filling head 104 for filling the automotive urea inside the solenoid valve tube 103.

[0026] The positioning mechanism 2 includes a shaft frame 201 disposed on both sides of the top of the mounting base 102. A movable frame 202 is rotatably mounted inside the shaft frame 201. A slope plate 203 is fixedly connected to the bottom end of the movable frame 202. The slope plate 203 has a V-shaped cross section. A ball bearing 204 for guiding the container to be filled is disposed on one side of the slope plate 203. The ball bearing 204 is rotatably mounted on one side of the slope plate 203 at equal intervals. A limiting groove 205 is also disposed on one side of the slope plate 203. The limiting groove 205 is located at the center position on the same side of the slope plate 203 and the ball bearing 204. A drive assembly for driving the movable frame 202 to rotate is also disposed on the top of the mounting base 102.

[0027] The drive assembly includes housings 206 disposed on both sides of the top of the mounting base 102. A first motor 207 is fixedly connected inside the housings 206. The output end of the first motor 207 passes through one side of the housings 206 and is fixedly connected to one end of the support rod 208. The other end of the support rod 208 passes through one side of the shaft frame 201 and is fixedly connected to the movable frame 202.

[0028] The electric rod 101 is fixed to one side of the top of the bracket 1. The output end of the electric rod 101 passes through the top of the bracket 1 and is fixedly connected to the top of the mounting base 102. A solenoid valve tube 103 is fixedly connected to the center of the top of the mounting base 102. The top end of the solenoid valve tube 103 passes through the center of the top of the bracket 1. The bottom end of the solenoid valve tube 103 is connected to the top of the filling head 104 for conveying the urea to be filled.

[0029] After the solenoid valve tube 103 is connected to the external urea supply equipment, the automotive urea can be transported into the solenoid valve tube 103 and transported by the conveyor belt assembly at the bottom of the bracket 1 to the container to be filled with automotive urea.

[0030] The electric rod 101 drives the mounting base 102 to move, and the moving mounting base 102 drives the solenoid valve tube 103 to move, so that the filling head 104 moves vertically to the top of the container, and then the solenoid valve tube 103 is opened to deliver the automotive urea into the container to be filled, thus completing the filling operation.

[0031] The movable mounting base 102 synchronously drives the shaft frame 201 to move. The shaft frame 201 drives the slope plate 203 to move through the movable frame 202, and drives the support rod 208 to rotate through two sets of first motors 207. The support rod 208 drives the movable frame 202 to move in an arc position around the shaft frame 201 as the axis, thereby driving two sets of ball bearings 204 to abut against the outside of the container to be filled.

[0032] By cooperating with the ball bearing 204 through the V-shaped slope plate 203, the container to be filled can rotate along the surface of the slope plate 203 against the ball bearing 204 and move into the limiting groove 205.

[0033] The two sets of closed slope plates 203 can position the container to be filled to the inside of the closed limiting groove 205, so that the container to be filled is perpendicular to the filling head 104, realizing the positioning and filling function of the container to be filled, and solving the problem of container position displacement during filling, resulting in urea leakage, equipment pollution and urea waste.

[0034] After filling is completed, the first motor 207 runs in reverse, driving the support rod 208 to rotate in the opposite direction. The support rod 208 drives the moving frame 202 to move in a reverse arc around the shaft frame 201 as the axis, thereby driving the two sets of slope plates 203 to move away from each other, breaking away from the contact with the container to be filled, and achieving reset.

[0035] The electric rod 101 reverses and drives the mounting base 102 to move upward. The mounting base 102 drives the solenoid valve tube 103 and the filling head 104 to move upward synchronously, so that the filling head 104 is disengaged from the top of the container to be filled, thus achieving reset.

[0036] The housing 206 is used to house and fix the first motor 207, and to provide protection for the first motor 207.

[0037] Second implementation method:

[0038] During the filling operation, it was also found that automotive urea is sensitive to carbon dioxide. If the filling head is left open for too long after filling, the solution will absorb carbon dioxide from the air and generate ammonium carbonate, resulting in a low urea concentration, which reduces the reduction efficiency of nitrogen oxides. This leads to quality differences in subsequent fillings and a decrease in urea quality. Therefore, this device is also designed with a sealing component, specifically as follows:

[0039] refer to Figure 4-5In the second embodiment of this utility model, a sealing assembly 3 is also included. The sealing assembly 3 includes a second motor 301 for providing a power source, a shaft 302 for transmitting the rotational power of the second motor 301, a crossbar 303 for providing an installation position, a vertically movable moving rod 304, a spring 305 for elastically abutting the moving rod 304 to reset, and a rubber sealing seat 306 for abutting the bottom end of the filling head 104 to achieve a seal.

[0040] The second motor 301 is mounted on the top of the mounting base 102. The output end of the second motor 301 passes through the top of the mounting base 102 and is fixedly connected to the top of the shaft 302. The top of one end of the crossbar 303 is fixedly connected to the bottom end of the shaft 302. The moving rod 304 is movably passed through the interior of one end of the crossbar 303. A spring 305 for applying elastic restoring force to the moving rod 304 is sleeved on the outer side of the bottom end of the moving rod 304. A rubber sealing seat 306 for sealing the bottom of the filling head 104 is fixedly connected to the top of the moving rod 304.

[0041] The rubber sealing seat 306 is made of wear-resistant rubber material to reduce frictional wear between the rubber sealing seat 306 and the bottom of the filling head 104.

[0042] After the filling operation is completed, the second motor 301 runs and drives the shaft 302 to rotate. The shaft 302 drives the crossbar 303 to move in a semi-arc position, so that the rubber sealing seat 306 abuts against the bottom of the filling head 104.

[0043] After the rubber sealing seat 306 is subjected to the contact force at the bottom of the filling head 104, the elastic force of the spring 305 drives the moving rod 304 to move downward, so that the rubber sealing seat 306 moves to the center of the bottom of the filling head 104, achieving precise alignment;

[0044] Spring 305 drives rubber sealing seat 306 to abut and seal the bottom of filling head 104 via moving rod 304, thereby achieving the sealing function of filling head 104. This solves the problem that automotive urea is sensitive to carbon dioxide. If the filling head 104 is left open for too long after filling, the solution will absorb carbon dioxide from the air and generate ammonium carbonate, resulting in a low urea concentration, reduced reduction efficiency of nitrogen oxides, and consequently, quality differences in subsequent fillings and a decline in urea quality.
