Automated systems are typically only used for larger quantities of oil additives in plastic modification, leading to high costs. Smaller quantities of oil additives are typically stored in containers, which can lead to incomplete pouring and easily lead to imbalanced proportions. Simple automatic oil metering systems accurately measure oils every time except the first one, reducing human error and labor. Utility Model Content

[0034] Implementation Method 1

[0035] Reference Figures 1 to 3 This embodiment, as an optional embodiment of the present application, discloses an automatic metering system, including an oil storage tank 1 and a conveying module. The oil storage tank 1 is an overall cylindrical structure, and a guide plate 6 is provided on its bottom surface. Along the radial direction of the oil storage tank 1, the guide plate 6 is inclined, that is, one end of the guide plate 6 is upwardly tilted and the other end is downwardly tilted, and is connected to the bottom surface of the oil storage tank 1;

[0036] The inclination angle of the guide plate 6 is 5-10 degrees. The above arrangement can ensure the flatness of the bottom of the oil storage tank 1, making it convenient to place the oil storage tank 1. On the other hand, a slope can be formed on the inner wall of the oil storage tank 1, thereby guiding the oil at the bottom to gather in a smaller area at the bottom of the oil storage tank 1, thereby facilitating the complete pumping of the oil and avoiding oil residue.

[0037] The delivery module includes a delivery pump 7, the inlet end of the delivery pump 7 is connected to an oil extraction pipe, and the inlet end of the oil extraction pipe is inserted into the oil storage tank 1;

[0038] At the same time, an oil delivery pipe 8 is also connected to the outlet end of the delivery pump 7;

[0039] The automatic metering system includes a temporary storage tank 2, which is generally cylindrical in structure with a completely open top. A conical collecting drum is integrally connected to the bottom of the collecting drum, and a first discharge pipe 15 is connected to the bottom of the collecting drum. The oil delivery pipe 8 is made of a hard pipe such as a steel pipe or a plastic pipe. The outlet end of the oil delivery pipe 8 is inserted into the temporary storage tank 2 through the opening area at the top of the temporary storage tank 2, and the oil delivery pipe 8 does not come into contact with the inner wall of the temporary storage tank 2.

[0040] The first discharge pipe 15 is provided with a regulating valve 3, and the oil delivery pipe 8 is provided with a solenoid valve 10. The regulating valve 3 and the solenoid valve 10 respectively control the on-off state of the corresponding pipes, thereby realizing the closing and opening of the pipes in a timely manner, which is conducive to improving the control accuracy;

[0041] The automatic metering system also includes a metering module, which includes a gravity sensor 11 and an intelligent quantity controller 12. The gravity sensor 11 and the intelligent quantity controller 12 are electrically connected; the intelligent quantity controller 12 is used to set measurement numbers for each gravity sensor 11 respectively. At the same time, each intelligent quantity controller 12 is equipped with a branch PLC, and each branch PLC is further connected to the master control PLC in the controller;

[0042] The top of the temporary storage tank 2 is connected to a door frame 13, and the middle part of the door frame 13 is threadedly connected to a pull rod 14. The top of the pull rod 14 is connected to the gravity sensor 11, connecting the temporary storage tank 2 to the gravity sensor 11; the top of the gravity sensor 11 is provided with a hook, which is connected to an external hanging device through the hook;

[0043] The above-mentioned structural setting can ensure that the metering module is only connected to the temporary storage tank 2 and is not directly connected to other components, thereby ensuring the independence of the metering module and avoiding interference with the temporary storage tank 2 by external equipment, especially various pipelines, thereby ensuring the accuracy of measurement;

[0044] The automatic metering system also includes a mixing tank 4 and a controller 5. The outlet end of the first discharge pipe 15 is inserted into the mixing tank 4. The controller 5 includes an industrial control computer and a PLC. The industrial control computer is electrically connected to the PLC, and the PLC is electrically connected to the delivery pump 7, the regulating valve 3, and the solenoid valve 10, respectively; thereby realizing automatic control of the entire device.

[0045] Furthermore, along the flow direction of the oil, a plurality of oil delivery branch pipes 9 are sequentially provided at the outlet end of the oil delivery pipe 8. Each of the oil delivery branch pipes 9 is also made of a hard pipe. Each of the oil delivery branch pipes 9 is provided with a solenoid valve 10. Each of the solenoid valves 10 is electrically connected to the PLC in the controller 5. The automatic metering system also includes a plurality of temporary storage tanks 2. Each of the temporary storage tanks 2 corresponds to each of the oil delivery branch pipes 9. That is, one oil delivery branch pipe 9 is inserted into one temporary storage tank 2, thereby realizing separate oil delivery for each temporary storage tank 2. Each of the temporary storage tanks 2 is equipped with a set of metering modules.

[0046] In actual use, each oil delivery branch pipe 9 is numbered, and the intelligent quantity controller 12 equipped with each temporary storage tank 2 sets the oil delivery volume for each of them. The industrial computer and PLC as the main controller 5 deliver oil to each temporary storage tank 2 according to the number.

[0047] By means of the above technical measures, multiple temporary storage tanks 2 are connected in parallel to the same system, and the oil volume is monitored separately. Therefore, the present application can not only realize the synchronous oil pumping and filling of multiple temporary storage tanks 2, but also can fill them one by one, meeting the use requirements of various working conditions and improving the working efficiency of the system as much as possible.

[0048] Furthermore, a feeding funnel 16 is provided at the inlet end of each mixing tank 4, and a second discharge pipe 17 inserted into the mixing tank 4 is provided at the outlet end of the feeding funnel 16; the first discharge pipe 15 is inserted into the inlet end of the feeding funnel 16, and the first discharge pipe 15 does not contact the inner wall of the feeding funnel 16;

[0049] When the feeding funnel 16 is provided, the top of the mixing tank 4 can be closed to avoid splashing of materials during the mixing process; secondly, the feeding funnel 16 can ensure that the first discharge pipe 15 and the mixing tank 4 are in a separated state while avoiding oil leakage, thereby preventing the mixing tank 4 from interfering with the metering module and improving the detection accuracy.

[0050] Compared with the existing technology, the present invention can realize automatic weighing, automatic addition and automatic discharge of materials, and the entire process of quantitative extraction of oil is automated, which not only simplifies the operation procedure of oil extraction, but also reduces the labor intensity of staff;

[0051] Secondly, since the technical solution described in the present application realizes fully automatic operation and no longer requires manual operation, it can also effectively avoid the safety hazards caused by oil dripping, especially the damage to the health of workers, and effectively improve the working environment of workers. At the same time, the fully automated operation can also avoid the problem of inaccurate measurement caused by manual intervention, thereby improving the accuracy of oil measurement.

[0052] Finally, compared with the large-scale automated weighing system in the prior art, the structure of the present application is relatively simple, which can effectively control the cost of the entire device, is suitable for the automatic addition of various oil additives with smaller amounts, and is conducive to improving the economic benefits of the enterprise.

[0053] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
