Description

Technical Field

[0001] The utility model relates to the technical field of filling machines, in particular to an Internet of Things filling machine. Background Art

[0002] Urea filling machines for vehicles are used to fill diesel vehicles with "urea solution". "Urea solution" is the common name for diesel vehicle exhaust treatment fluid, which is mandatory for the state to be used to treat diesel vehicle exhaust. It is understood that all diesel vehicles that meet the National IV standard or above in my country are mandatory to install SCR (an oxidation catalytic technology) systems. After filling with exhaust treatment fluid (that is, "urea solution"), it can reduce 90% of nitrogen oxides and 80% of particulate matter in diesel vehicle exhaust, greatly reducing the air pollution caused by large vehicles. With the country's emphasis on air quality, the market for urea filling machines for vehicles is getting bigger and bigger, spreading across the country, and more and more urea filling machines for vehicles are appearing in gas stations in many cities.

[0003] In order to prevent urea from crystallizing at low temperatures, the existing automotive IoT urea filling machine has added a function of heating urea. However, when filtering the transported urea solution, it is inconvenient to clean the impurities deposited on the filter in the filling machine.

[0004] For example, the Chinese patent publication number is CN215439666U, which is an Internet of Things urea filling machine with an automatic pressure-maintaining function, including a filling machine body, a box body is fixedly connected to the top of the inner cavity of the filling machine body, a water pump is fixedly connected to the bottom of the inner cavity of the filling machine body, and the top of the water pump is connected to a first water inlet pipe. By arranging a shell and a heating wire, urea can be heated to avoid crystallization. By arranging a water pump, a first water inlet pipe, a filter box and a second water inlet pipe, the urea in the inner cavity of the box is output, and the purity of the urea is improved by filtering through a filter. Finally, the urea is output to the outside through a water outlet pipe and a hose and a filling gun. By arranging the above structure, the advantage of heating urea is achieved, which solves the problem that the existing urea filling machine does not have the function of heating urea, thereby facilitating the use of the device.

[0005] In the above scheme, when urea is output, it needs to be filtered through a filter to improve the purity of the urea. However, when used for a long time, the impurities deposited on the filter will affect the urea transportation efficiency. When cleaning, it is necessary to open the box door and clean the impurities on the filter, which is not only troublesome but also affects the work efficiency of urea transportation. In view of this, we propose an Internet of Things filling machine. Utility Model Content

Its main purpose is: when the electric push rod 128 drives the scraper 130 to move toward the side of the sealing door 126, the impurities on the first filter plate 127 are driven to move to the side of the sealing door 126, and the torsion spring drives the sealing door 126 to have a certain torque, so that the pushed impurities are squeezed by the scraper 130 and the sealing door 126, so that the urea in the impurities is easily squeezed out. When the electric push rod 128 continues to work, it drives the scraper 130 to push the sealing door 126 to open the sealing door 126, and then pushes the impurities removed from the solution into the sedimentation box 124 for collection.

[0027] Working principle:

[0028] When the filling machine body 100 is in use, the solenoid valve 122 is first opened, and the exhaust gas treatment liquid is added to the vehicle through the filling mechanism. When the exhaust gas treatment liquid is added, the urea solution in the storage box 120 passes through the guide pipe 121 and the solenoid valve 122 to reach the filter box 123, and is filtered by the first filter plate 127 before being filled into the vehicle;

[0029] After the filling machine body 100 has been used for a period of time, the solenoid valve 122 is first closed, and then the electric push rod 128 is driven. When the electric push rod 128 is working, it drives the scraper 130 to move to the side of the sealing door 126, and drives the impurities deposited on the first filter plate 127 to move together, and then the urea solution in the impurities is squeezed out under the pressure of the scraper 130 and the sealing door 126. The electric push rod 128 continues to work, driving the scraper 130 to push the sealing door 126 open, and the impurities removed from the urea solution are pushed into the sedimentation box 124.

[0030] The above-mentioned filling mechanism includes a water inlet pipe 140, which is connected to the bottom of the filter box 123. A water pump 141 is fixedly provided on the side of the empty slot 112 away from the sedimentation box 124. The end of the water inlet pipe 140 away from the filter box 123 is connected to the water inlet of the water pump 141, and the water outlet of the water pump 141 is connected to a hose 142. A connecting plate 143 is fixedly provided on the outer wall of one end of the filling machine body 100, and a filling gun 144 is clamped on the top of the connecting plate 143. The end of the hose 142 away from the water pump 141 is connected to the filling gun 144. When the solenoid valve 122 and the water pump 141 are opened, the filling gun 144 can spray out urea solution.

[0031] In order to facilitate the replacement of the first filter plate 127, fixed plates 150 are fixedly provided on the inner walls at both ends of the filter box 123 near the middle position. The fixed plates 150 are of an inclined structure, and the height of the fixed plates 150 near one end of the sedimentation box 124 is higher than that of the other end. A pair of fixed blocks 151 that movably cooperate with the fixed plates 150 are fixedly provided at the bottom of both ends of the first filter plate 127, thereby not only preventing the first filter plate 127 from being tilted by the impact of the solution and affecting the filtration, but also achieving the effect of facilitating the removal of the first filter plate 127.

[0032] At the same time, the scraper 130 mentioned above includes a top plate 131, the movable end of the electric push rod 128 is fixedly connected to the outer wall of one side of the top plate 131, and a moving groove 132 is opened at the bottom of the top plate 131, and a bottom plate 133 is slidably arranged in the moving groove 132. A plurality of telescopic rods 134 are fixedly arranged on the top wall of the moving groove 132, and the bottom of the telescopic rod 134 is fixedly connected to the top of the bottom plate 133. A spring 135 is arranged on the periphery of the telescopic rod 134, one end of the spring 135 is fixedly connected to the top wall of the moving groove 132, and the other end of the spring 135 is fixedly connected to the top of the bottom plate 133, and the bottom of the bottom plate 133 conflicts with the top of the first filter plate 127. Because the first filter plate 127 remains in an inclined state in the filter box 123 under the action of the fixed plate 150, when the electric push rod 128 drives the scraper 130 to move, under the action of the spring 135, the bottom of the bottom plate 133 always remains in conflict with the top of the first filter plate 127, so as to avoid unclean cleaning of impurities.

[0033] In order to prevent dangerous situations caused by over-high temperature inside the filling machine body 100 and to facilitate maintenance of the filling machine body 100, a through inspection port 160 is opened on the side of the empty slot 112 close to the sedimentation box 124, and an inspection door 161 is hinged in the inspection port 160. By opening the inspection door 161, it is convenient to inspect the inside of the filling machine body 100, and heat dissipation slots 162 are opened on both sides of the circular slot 111, which can help dissipate heat inside the filling machine body 100.

[0034] In addition, in order to avoid the presence of a small amount of urea solution in the impurities in the sedimentation box 124, a second filter plate 170 is fixedly provided near the middle of the sedimentation box 124, and a drain pipe 171 connected to the sedimentation box 124 is fixedly provided at the bottom of the outer wall on one side of the sedimentation box 124 near the inspection port 160. A valve 172 is provided on the drain pipe 171. Impurities fall from the filter box 123 onto the second filter plate 170. If there is a small amount of solution in the impurities, it can drip into the bottom of the sedimentation box 124 through the second filter plate 170 under the action of gravity. When a large amount of solution accumulates in the sedimentation box 124, the valve 172 can be opened to discharge the solution.

[0035] In addition, in order to prevent the urea solution from crystallizing in a low temperature environment, heating wires 129 are provided on the inner walls around the storage box 120, and the bottom of the storage box 120 is a conical structure.

[0036] When the IoT filling machine of this embodiment is used, when adding exhaust gas treatment liquid to a vehicle, the filling gun 144 is firstly aimed at the filling port of the vehicle, and then the switches of the solenoid valve 122 and the water pump 141 are turned on. At this time, the urea solution in the storage box 120 passes through the guide pipe 121 and the solenoid valve 122 to reach the filter box 123, and the pure solution flows into the water inlet pipe 140 through the first filter plate 127, and then passes through the water pump 141 and the hose 142, and finally flows out from the outlet of the filling gun 144, while the impurities in the urea solution remain on the top of the first filter plate 127;

[0037] After the filling machine body 100 has been used for a period of time, the solenoid valve 122 and the water pump 141 are turned off, and then the electric push rod 128 is driven. The movable end of the electric push rod 128 drives the scraper 130 to move to the side where the sealing door 126 is located, and under the action of the spring 135, the bottom of the bottom plate 133 in the scraper 130 always keeps in contact with the top of the first filter plate 127, thereby driving the impurities on the top of the first filter plate 127 to move, until the impurities are squeezed under the action of the sealing door 126 and the scraper 130, and the urea solution in the impurities is squeezed out, and finally the impurities are pushed to open the sealing door 126, and fall from the cleaning port 125 into the sedimentation box 124, and finally fall on the top of the second filter plate 170 in the sedimentation box 124. When there is still a small amount of solution in the impurities, it can drip into the bottom of the sedimentation box 124 through the second filter plate 170 under the action of gravity;

[0038] The inspection door 161 is opened regularly to check the amount of impurities accumulated in the sedimentation box 124 for regular cleaning, and when a large amount of solution accumulates in the sedimentation box 124, the valve 172 can be opened to discharge the solution.
