Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and more particularly to a refueling metering device. Background Technology
[0002] In the production of titanium tetrachloride, the metering of mineral oil added to the reaction tank is a key factor in ensuring stable production processes and controllable product quality. However, current metering methods for adding oil to reaction tanks have significant shortcomings in practical applications. The adding process often cannot be carried out at a uniform speed, with inconsistent rates. This results in large amounts of oil rushing into the reaction tank in a short period or dripping slowly. This unstable rate variation causes numerous problems for subsequent production stages. Furthermore, the metering accuracy is difficult to achieve ideal levels, and deviations in the amount of oil added may exceed the allowable error range of the production process. This inaccuracy in metering makes it difficult to precisely control the material ratios and reaction conditions within the reaction tank, thus significantly impacting the overall production process control. This can lead to unstable product quality, batch-to-batch variations, increased production costs, reduced production efficiency, and even, in some cases, safety hazards. Therefore, there is an urgent need for a technical solution that can achieve uniform and accurate metering of oil added to address this prominent problem in existing technologies and meet the high precision and stability requirements of industrial production for metering oil added to reaction tanks.

[0024] Example 1
[0025] like Figure 1 As shown, this utility model provides a refueling metering device, including an oil tank 1, a static scale 3, a plunger pump 5, a flow meter 6, and a radar level gauge 7;
[0026] The oil tank 1 is placed on the static scale 3, which is used to weigh the oil tank 1 in real time.
[0027] The top of the oil tank 1 is equipped with a radar level gauge 7 for real-time monitoring of the mineral oil level in the oil tank 1;
[0028] The oil outlet of the oil tank 1 is connected to the inlet of the plunger pump 5 through a pipeline, and the outlet of the plunger pump 5 is connected to the titanium tetrachloride reaction tank 11 through a pipeline. The plunger pump 5 is used to transport the mineral oil in the oil tank 1 to the reaction tank 11. The flow meter 6 is installed on the pipeline between the plunger pump 5 and the reaction tank 11 and is used to monitor the flow rate of the mineral oil in the pipeline in real time.
[0029] Furthermore, the filler port 8 of the fuel tank 1 is located at the top.
[0030] Furthermore, a heater 2 extending into the oil tank 1 is fixedly installed on the side wall of the oil tank 1 for heating the mineral oil in the oil tank 1.
[0031] Furthermore, since the mineral oil has a high viscosity, the oil tank 1 is equipped with a circulation pump 4. The inlet and outlet of the circulation pump 4 are respectively connected to the inside of the oil tank 1 through pipes. The mineral oil in the oil tank 1 can flow inside the oil tank 1 through the circulation pump 4. In conjunction with the heater 2, the mineral oil can be heated evenly, so that the mineral oil added to the reaction tank 11 is kept at a constant temperature.
[0032] Furthermore, the plunger pump 5 is a plunger pump with a frequency converter.
[0033] Furthermore, a bypass pipe 9 is installed on the pipeline between the plunger pump 5 and the reaction tank 11. The two ends of the bypass pipe 9 are respectively connected to the pipelines at both ends of the flow meter 6. A bypass pipe flow meter for real-time monitoring of mineral oil flow is also installed on the bypass pipe 9, which serves as a backup pipeline. Valves are installed on the pipelines on both sides of the flow meter 6 and on the pipelines on both sides of the bypass pipe flow meter. When the flow meter 6 has an excessive error and needs to be removed for cleaning and maintenance, the valves on both sides of the flow meter 6 can be closed, and the bypass pipe 9 can be used to deliver mineral oil to the reaction tank 11, thereby enabling maintenance and replacement of the flow meter 6 without affecting production. When the pipeline where the flow meter 6 is located malfunctions, the flow of mineral oil can also be switched to the bypass pipe 9 by controlling the opening and closing of the valves, thereby effectively ensuring the normal operation of production.
[0034] Furthermore, it also includes a nitrogen blowing device 10, the nitrogen outlet of which is connected to a pipeline between the flow meter 6 and the reaction tank 11, for blowing nitrogen into the pipeline; the nitrogen blowing device 10 blowing nitrogen into the pipeline has two functions: first, before the device is started, nitrogen is blown into the pipeline at intervals, so that the mineral oil can flow into the reaction tank 11 through the pipeline; second, when the device is shut down, the pipeline can be purged with nitrogen to prevent titanium tetrachloride in the reaction tank 11 from entering the pipeline and reacting with the mineral oil, causing pipeline blockage.
[0035] When using the refueling metering device described in this utility model, the mineral oil is heated to 120°C by the heater 2 and combined with the circulation pump 4 to achieve flow and constant temperature effect. Then, the mineral oil is delivered to the reaction tank 11 in batches at a uniform speed and stable speed by the plunger pump 5 (with frequency converter) at the oil outlet of the oil tank 1.
[0036] During the process of adding oil to the reaction tank 11 using the device of this application, the radar level gauge 7 monitors the mineral oil level in the oil tank 1 as the first-level oiling measurement, the static scale 3 below the oil tank 1 as the second-level oiling measurement, and the flow meter 6 installed on the pipeline between the plunger pump 5 and the reaction tank 11 monitors the mineral oil flow rate as the third-level oiling measurement.
[0037] The aforementioned device can be used to add oil to the reaction tank 11 in batches. A fixed amount of mineral oil is added to the oil tank 1 for each batch. Before adding oil to the reaction tank 11, the liquid level information monitored by the radar level gauge 7 determines whether the amount of oil added meets the requirements. Simultaneously, the overall weight of the oil tank 1 before and after adding oil can be monitored by the static scale 3 to more accurately determine whether the amount of oil added meets the requirements for each batch. When adding oil to the reaction tank 11 through the plunger pump 5, the radar level gauge 7 can monitor the changes in the liquid level in the oil tank 1 in real time, reflecting the real-time addition amount. At the same time, the flow meter 6 on the oil pipeline can monitor the flow rate of the mineral oil in real time. Based on the monitoring results, the operating parameters of the plunger pump 5 can be adjusted in real time to regulate the flow rate, ensuring that the oil is added to the reaction tank 11 in a controlled manner. For uniform refueling of oil tank 1, due to the adhesive nature of mineral oil, this application also sets up a more accurate static scale 3 in addition to using the data monitored by the radar level gauge 7 as a refueling measurement reference. The static scale 3 can monitor the actual amount used and calibrate the data monitored by the flow meter. During the refueling process, by periodically determining the overall weight change of the oil tank 1 monitored by the static scale 3, it is possible to further determine whether the total amount of refueling within the period meets the requirements, that is, to monitor the actual amount of refueling. Furthermore, since the monitoring results of the flow meter 6 are prone to errors, by periodically comparing the monitoring data of the static scale 3 and the flow meter 6, problems with the flow meter 6 can be detected in time, and periodic corrections can be made based on the data monitored by the flow meter 6.
[0038] The refueling metering device described in this utility model has the characteristics of high efficiency, simple operation and low cost. It uses a static scale, radar level gauge and flow meter to perform three-stage refueling metering, thereby ensuring that mineral oil can be added to the reaction tank for titanium tetrachloride production at a uniform and stable rate, thus ensuring stable production and process quality.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
