Description

Technical Field

[0001] This utility model relates to the field of fuel additive production technology, specifically a fuel additive filling equipment. Background Technology

[0002] The most common function of fuel additives is to clean the fuel system and fuel injection system. Over time, impurities, oil stains, or carbon deposits may accumulate in the fuel injectors and fuel system of a car, especially in urban environments with frequent starts and stops. The chemical components in fuel additives can help clean carbon deposits in the fuel injectors, valves, combustion chamber, and other parts, thereby improving fuel injection and combustion efficiency. This results in smoother power output and potentially improved fuel economy. Fuel additive production and packaging typically involve filling machines to fill the bottles with the fuel additive solvent. To increase the filling efficiency of these machines, specialized automatic fuel additive filling equipment is used. Existing filling machines generally use a pump to deliver liquid to the filling head, while a flow meter measures the liquid flow. A PLC then controls the pump to stop. While this method is simple and convenient, liquid remains inside the filling head after it stops. Therefore, during the loading and unloading of containers, this liquid can easily leak and drip, contaminating the container surface and affecting the production quality of the fuel additive filling equipment. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: a fuel additive filling device, including a frame 1;

[0021] Frame 1: Its rear end is equipped with a liquid metering delivery assembly. Frame 1 provides support for the components above. The front end of frame 1 is equipped with a filling tube 4. The front end of the liquid metering delivery assembly is connected to the rear end of the filling tube 4. The filling tube 4 is inserted into the container. An air blowing tube 5 is slidably connected inside the filling tube 4. A conical sleeve 7 is provided at the lower end of the filling tube 4. A valve core 6 is provided at the lower end of the air blowing tube 5. The valve core 6 is movably inserted into the conical sleeve 7. The upper end of the air blowing tube 5 extends out of the filling tube 4 and is equipped with a balloon inflation ball 13. A Z-shaped seat 12 that can move up and down is provided at the upper end of the air blowing tube 5. The Z-shaped seat 12 drives the valve core 6 to move upward through the air blowing tube 5. The valve core 6 separates from the conical sleeve 7, opening the lower end of the filling tube 4. The balloon inflation ball 13 is located at the Z-shaped seat 1. Between the filling tube 4 and the filling tube 2, a PLC controller 15 is installed at the front end of the frame 1. The input terminal of the PLC controller 15 is electrically connected to the output terminal of an external controller. The liquid metering delivery assembly includes a metering pump 2 and a turbine flow meter 3. The metering pump 2 is located at the rear end of the upper surface of the frame 1. The outlet end of the metering pump 2 is equipped with a turbine flow meter 3. The front end of the turbine flow meter 3 is connected to the rear end of the filling tube 4. The input terminal of the metering pump 2 is electrically connected to the output terminal of the PLC controller 15, and the output terminal of the turbine flow meter 3 is electrically connected to the input terminal of the PLC controller 15. The metering pump 2 delivers the liquid inside the liquid storage container to the inside of the filling tube 4 through the turbine flow meter 3. The turbine flow meter 3 converts the liquid flow rate into an electrical signal and transmits it to the PLC controller 15. The PLC controller 15 can monitor the flow rate. The upper end of the filling tube 4 is provided with two guide shafts 9, both of which are slidably connected to the Z-shaped seat 12. A mounting plate 10 is provided at the upper end between the two guide shafts 9. An electromagnetic push-pull rod 11 is located in the middle of the mounting plate 10, providing a mounting position for the electromagnetic push-pull rod 11. The telescopic end of the electromagnetic push-pull rod 11 is fixedly connected to the Z-shaped seat 12. The input end of the electromagnetic push-pull rod 11 is electrically connected to the output end of the PLC controller 15. The retraction of the telescopic end of the electromagnetic push-pull rod 11 causes the Z-shaped seat 12 to move upwards along the guide shafts 9. The system also includes two springs 14, each movably sleeved on the outside of the guide shafts 9. The springs 14 are located between the mounting plate 10 and the Z-shaped seat 12. Between points 2 and 3, the Z-shaped seat 12 moves upward, compressing the spring 14 and simultaneously releasing the balloon inflation ball 13. The balloon inflation ball 13 naturally bounces up, drawing air from the air blowing tube 5. The spring 14 pushes the Z-shaped seat 12 downward quickly. The Z-shaped seat 12, through the air blowing tube 5, drives the valve core 6 downward. The valve core 6 contacts the conical sleeve 7, sealing the lower end of the filling tube 4 to prevent leakage. At the same time, the Z-shaped seat 12 compresses the balloon inflation ball 13, flattening it and blowing air into the inside of the air blowing tube 5. The lower end of the air blowing tube 5 is provided with evenly distributed connecting strips 16. The lower surface of each connecting strip 16 is fixedly connected to the upper surface of the disc 8, facilitating the connection of the disc 8. The airflow flows out circumferentially through the gap between the air blowing tube 5 and the disc 8.This allows for air blowing onto the lower surfaces of the valve core 6, conical sleeve 7, and filling tube 4, promoting rapid separation of surface droplets. The upper side wall of the filling tube 4 is equipped with a mounting ring 17, inside which is a rubber ring 18. The mounting ring 17 provides a mounting position for the rubber ring 18, which is slidably connected to the air blowing pipe 5, sealing the connection between the air blowing pipe 5 and the filling tube 4.

[0022] The working principle of the fuel additive filling equipment provided by this utility model is as follows: During use, the liquid extraction end of the metering pump 2 is connected to an external fuel additive liquid storage container. During filling, the container is placed below the filling tube 4. The external support device moves the container upwards, and the filling tube 4 is inserted into the container. The PLC controller 15 is adjusted, and the metering pump 2 and electromagnetic push-pull rod 11 operate. The telescopic end of the electromagnetic push-pull rod 11 retracts, causing the Z-shaped seat 12 to move upwards along the guide shaft 9. The upward movement of the Z-shaped seat 12 compresses the spring 14 and simultaneously releases the balloon inflation ball 13. The balloon inflation ball 13 naturally bounces up, drawing air from the air blowing pipe 5. At the same time, the Z-shaped seat 12, through the air blowing pipe 5, moves the valve core 6 upwards. The valve core 6 separates from the conical sleeve 7, opening the lower end of the filling tube 4. Then, the metering pump 2 delivers the fuel additive liquid from the fuel additive liquid storage container to the inside of the filling tube 4 through the turbine flow meter 3, and then fills the container below. During filling, the turbine flow meter 3 converts the flow rate of the fuel additive liquid into an electrical signal and transmits it to the PLC controller 15. The PLC controller 15 can monitor the flow rate. When the flow rate reaches the set value, the PLC controller 15 controls the metering pump 2 and the electromagnetic push-pull rod 11 to stop working. The spring 14 pushes the Z-shaped seat 12 to move down quickly. The Z-shaped seat 12 drives the valve core 6 to move down through the air blowing pipe 5. The valve core 6 contacts the conical sleeve 7 to seal the lower end of the filling tube 4, preventing leakage. At the same time, the Z-shaped seat 12 will squeeze the balloon inflation ball 13. The balloon inflation ball 13 flattens and blows air into the inside of the air blowing pipe 5. Then the airflow flows out around the circumference through the gap between the air blowing pipe 5 and the disc 8, which can blow air onto the lower surface of the valve core 6, the conical sleeve 7 and the filling tube 4, promoting the rapid separation of surface droplets. Then the container is lowered and removed, thus preventing the filled fuel additive product from dripping onto the surface of the container.

[0023] It is worth noting that the metering pump 2, turbine flow meter 3, electromagnetic push-pull rod 11, and PLC controller 15 disclosed in the above embodiments can all be freely configured according to the actual application scenario. The metering pump 2 can be a DJ-D series diaphragm metering pump, the turbine flow meter 3 can be a sanitary turbine flow meter of the LWS-SIN series, the electromagnetic push-pull rod 11 can be a push-pull electromagnet of the LY1264 model, and the PLC controller 15 can be a PLC controller of the MM-24MR-4MT-500-FX-A model. The PLC controller 15 controls the operation of the metering pump 2, turbine flow meter 3, and electromagnetic push-pull rod 11 using methods commonly used in the prior art.
