Abstract
Description
Technical Field
[0001] This utility model relates to the chemical industry, and in particular to an automated production equipment for adding additives. Background Technology
[0002] In the chemical industry, white oil, as an important petroleum product, is widely used in many fields. White oil typically refers to mineral oil processed through special refining techniques, and its main components are saturated hydrocarbon compounds. Specifically, it contains a large number of straight-chain alkanes, branched alkanes, and cycloalkanes, which constitute the basic chemical framework of white oil. Straight-chain alkanes give white oil good chemical stability, making it less prone to deterioration under normal chemical reaction conditions; branched alkanes help adjust the viscosity and flowability of white oil to meet the physical property requirements of different application scenarios; the presence of cycloalkanes further optimizes the solubility and lubricity of white oil, enabling it to play an important role in lubricants, cosmetics, and other fields.
[0003] In addition, white oil may contain trace amounts of aromatics, but in high-quality white oil products, the aromatic content is strictly controlled to reduce its potential harm to human health and the environment. Besides hydrocarbon compounds, white oil inevitably contains trace amounts of impurities, such as compounds of sulfur, nitrogen, and oxygen, as well as some metal ions. Although these impurities are present in very small amounts, they can significantly affect the performance of white oil. For example, sulfur and nitrogen compounds may reduce the antioxidant properties of white oil, while metal ions may catalyze the oxidation reaction of the oil, accelerating its aging.
[0004] To improve the performance of white oil and meet the stringent requirements of specific industries, it is often necessary to add a mixture of additives, including sorbitan monooleate and polymer stabilizers. The main purpose of adding these additives is to enhance the antioxidant, thermal, and light stability of the white oil.
[0005] Currently, the industrial sector commonly uses a batch-by-batch method to add additives to white oil. This indirect batch-by-batch blending process has many limitations, severely restricting production efficiency and economic benefits. In terms of manpower, each batch requires significant manual labor, from metering and feeding white oil and additives to monitoring the mixing process and discharging the finished product—all requiring specialized personnel, resulting in high labor costs. Material resources are also not utilized effectively; the single-batch processing capacity of the batch-by-batch equipment is limited, and the maintenance and cleaning of the equipment are cumbersome, increasing equipment wear and tear and operating costs. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a production equipment that can automatically add additives to white oil in an assembly line, which can greatly improve production efficiency and reduce the number of production personnel required.
[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an automated additive production equipment, characterized in that it includes an oil fractionation tower, an oil discharge pump, a compound additive blending vessel group, a special mixer for oil and compound additives, a compound additive addition pump group, and an oil storage tank; the oil fractionation tower is connected to the oil discharge pump, which is connected to both the special mixer for oil and compound additives and the compound additive blending vessel group; the compound additive blending vessel group is connected to the compound additive addition pump group, which is connected to the special mixer for oil and compound additives; the special mixer for oil and compound additives is connected to the oil storage tank; the white oil produced by the oil fractionation tower is transported to the special mixer for oil and compound additives and the compound additive blending vessel group by the oil discharge pump; after the white oil in the compound additive blending vessel group is mixed with additives, it forms a compound additive; the compound additive is transported to the special mixer for oil and compound additives by the compound additive addition pump group to be mixed with the white oil; and finally, the mixed finished white oil is transported to the oil storage tank.
[0008] A further preferred embodiment of this utility model is as follows: the compound additive blending kettle group includes a first blending kettle and a second blending kettle, which are connected in parallel. Both the first blending kettle and the second blending kettle are equipped with a stirrer, a liquid level sensor and a hot water heating device.
[0009] A further preferred embodiment of this utility model is as follows: the compound additive addition pump assembly includes a first addition pump assembly and a second addition pump assembly, the first addition pump assembly and the second addition pump assembly are connected in parallel, and both the first addition pump assembly and the second addition pump assembly are provided with a pump and multiple switching valves.
[0010] A further preferred embodiment of this utility model is: a remote mass flow meter is provided between the compound additive addition pump group and the oil and compound additive special mixer.
[0011] A further preferred embodiment of this utility model is: the outlet of the oil discharge pump is connected to an air cooler, and the white oil is cooled and then transported to a special mixer for oil and compound additives and a compound additive blending kettle group.
[0012] A further preferred embodiment of this utility model is: a discharge regulating valve is provided between the air cooler and the special mixer for oil and compound additives.
[0013] A further preferred embodiment of this utility model is: the outlet of the oil and compound additive mixer is connected to a product sampler.
[0014] This invention establishes a complete and automated white oil additive production process. The white oil produced from the oil fractionation tower can be flexibly transported via an oil discharge pump, either directly into a dedicated oil and additive mixer or first into an additive blending reactor for additive preparation, thus achieving an automated mixing process for white oil and additives. Compared to the traditional batch-by-batch production method, this equipment enables continuous production, significantly reducing manpower. In traditional production, each batch requires manual operation of multiple steps such as raw material injection and additive addition. This equipment, through its automated process, reduces a large number of manual steps, improving production efficiency. For example, in large-scale production, output that might take several days using traditional methods can be achieved in a much shorter time with this equipment. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of the structure of this utility model;
[0016] Figure 2 This is a device for adding traditional additives. Detailed Implementation
[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0018] The general process of this invention is as follows: After white oil is formed in the oil fractionation tower, a small portion of the white oil is first extracted to prepare compound additives. When the compound additive blending kettle group begins blending, the oil temperature is first controlled to 65°C by air cooling. The flow rate is then changed to enter the first or second blending kettle. After checking the flow meter of the outlet device and the liquid level gauge of the blending kettle, a specific liquid level is added. The temperature is then lowered to 40°C, and the oil discharge flow is changed to the unqualified tank group. Then, different additives in specific proportions are added to the blending kettle, the stirrer is activated, and hot water is used for heating to begin blending the compound additives. After the compound additives are blended, the discharge flow and reagent injection distillation range of the first or second blending kettle are opened, and the injection pump is started to begin online injection. By calculating the flow meter of the oil outlet device and the flow meter of the injection pump outlet, the additive addition ratio is adjusted by the stroke of the injection pump to ensure that the oil and additives are uniformly mixed in the mixer. Samples can be taken for analysis after half an hour. Once specific indicators are qualified, the oil discharge process will be improved to meet the qualified tank group requirements.
[0019] like Figure 1As shown, the specific structure of this utility model is as follows: an automated additive addition production equipment, including an oil fractionation tower 1, an oil discharge pump 2, a compound additive blending vessel group (first blending vessel 3, second blending vessel 4), a dedicated mixer for oil and compound additives 5, a compound additive addition pump group (first addition pump assembly 6, second addition pump assembly 7), and an oil storage tank 8; the oil fractionation tower 1 is connected to the oil discharge pump 2, the oil discharge pump 2 is connected to the dedicated mixer for oil and compound additives 5 and the compound additive blending vessel group respectively, and the compound additive blending vessel group is connected to the compound additive addition pump group. The system connects to a dedicated mixer 5 for oil and additives, which in turn connects to an oil storage tank 8. White oil produced by the oil fractionation tower 1 is pumped via an oil discharge pump 2 to the dedicated mixer 5 and the additive blending vessel group. Additives are added to the white oil in the blending vessel group to form a compound additive mixture. This mixture is then pumped back to the dedicated mixer 5 to neutralize the white oil. Finally, the finished white oil is delivered to the oil storage tank 8. This equipment establishes a complete and automated white oil additive production process. The white oil produced by the oil fractionation tower 1 can be flexibly pumped via the oil discharge pump 2, either directly into the dedicated mixer 5 or first into the additive blending vessel group for additive blending, thus achieving an automated mixing process for white oil and additives. Compared to the traditional batch-by-batch production method, this equipment enables continuous production, significantly reducing manpower input. In traditional production, each batch requires manual operation involving multiple steps such as raw material injection and additive addition. This equipment, through its automated process, significantly reduces manual steps and improves production efficiency. For example, in large-scale production, output that might take several days using traditional methods can be achieved in a much shorter time with this equipment. Simultaneously, it effectively solves problems such as discontinuous production processes, low output, and wasted manpower in traditional production methods.
[0020] The compound additive blending vessel group includes a first blending vessel 3 and a second blending vessel 4, which are connected in parallel. Both the first and second blending vessels are equipped with a mixer 9, a liquid level sensor 10, and a hot water heating device 11. This dual-vessel parallel configuration allows one vessel to be used for additive blending while the other serves as a backup, enabling continuous production and preventing production interruptions caused by the blending of compound additives. The mixer 9 maintains a stable rotation speed to ensure thorough mixing of the additives and white oil. Compared to manual stirring or traditional equipment, this results in more uniform mixing, guaranteeing the homogeneity of the compound additives and improving the performance stability of the finished white oil. The liquid level sensor 10 monitors the liquid level in the vessel in real time, accurate to a specific scale value, facilitating precise control of the raw material and finished product quantities and preventing problems such as additive imbalance or raw material waste due to inaccurate liquid level readings. The hot water heating device 11 can heat the materials in the kettle according to the needs of additive formulation. Through a precise temperature control system, the temperature is controlled within a suitable range, which helps the additives to dissolve and mix better, improves the quality and stability of compound additives, and ensures that the finished white oil meets higher standards in terms of antioxidant properties, thermal stability and light stability.
[0021] The compound additive addition pump assembly includes a first addition pump component 6 and a second addition pump component 7, which are connected in parallel. Both the first and second addition pump components are equipped with pumps and multiple switching valves. This parallel configuration of the two pump components, one active and one standby, ensures a stable and continuous delivery of additives to the dedicated mixer 5 for oil and compound additives. If one pump malfunctions or requires maintenance, it can be switched to the other pump in a very short time (e.g., within seconds), ensuring uninterrupted production and maintaining continuity and stability. The multiple switching valves allow operators to flexibly control the additive delivery path and flow rate, precisely adjusting the amount of additive added to meet different production needs, thus improving production flexibility and controllability. For example, under different production formulations, the additive flow rate can be precisely adjusted via the switching valves to ensure the additive-to-white oil ratio always meets requirements, improving product quality consistency.
[0022] A remote mass flow meter 12 is installed between the compound additive addition pump unit and the dedicated mixer 5 for oil and compound additives. The remote mass flow meter 12 can measure the additive delivery flow rate in real time with high accuracy and transmit the data remotely to the control system. By comparing the flow data with that of the oil, operators can accurately adjust the operating parameters of the compound additive addition pump unit, such as the pump stroke, thereby precisely controlling the additive addition ratio. This ensures that the white oil and additives are uniformly mixed according to the preset ratio, improving the quality stability and consistency of the finished white oil and avoiding product quality problems caused by inaccurate additive addition ratios. For example, the amount of additive injected can be adjusted promptly based on real-time flow data to ensure that each batch of finished white oil maintains a high degree of consistency in performance indicators.
[0023] The outlet of the oil discharge pump 2 is connected to an air cooler 13. After cooling, the white oil is transported to the oil and compound additive mixer 5 and the compound additive blending vessel group. The air cooler 13 can effectively control the temperature of the white oil to achieve the appropriate production temperature requirements.
[0024] A discharge regulating valve 14 is installed between the air cooler 13 and the oil and compound additive mixer 5. The discharge regulating valve 14 can flexibly adjust the flow rate and pressure of white oil according to production needs. By precisely controlling the amount of white oil delivered, it can be matched with the amount of additives added, ensuring that the white oil and additives can be fully and uniformly mixed in the oil and compound additive mixer 5.
[0025] The outlet of the dedicated mixer 5 for oil products and compound additives is connected to a product sampler 15. The product sampler 15 facilitates real-time sampling and testing of the mixed finished white oil. Through periodic or irregular sampling and analysis, the quality of the finished white oil can be promptly assessed, including whether key indicators such as antioxidant properties, thermal stability, and light stability meet requirements. If product quality abnormalities are detected, corresponding measures can be quickly taken to adjust the situation, preventing the mass production of substandard products, improving product quality control and production efficiency, and reducing economic losses and resource waste caused by product quality issues.
[0026] Figure 2 This is a traditional additive addition device. It uses a pump to extract the finished white oil from the storage tank 21 and transport it into the mixing tank 22. Additives are added manually to form an additive mixture. Its production efficiency is low, the whole process is manually participated in, and the production cost is high.
[0027] The above provides a detailed description of an automated additive-adding production equipment provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
