Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil production, in particular to a lubricating oil blending system. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant between two relatively moving objects to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Usually, different types of lubricating oil raw materials are mixed and blended in a blending kettle to finally form a synthetic lubricating oil that meets the needs of use.

[0003] In the existing production process, a weighing system is usually installed on a blending kettle, which requires a lot of construction work and is costly. At the same time, the weighing system has a large measurement error, which affects product quality. In addition, when the blending kettle is injected with materials, overflow may occur, posing a safety hazard. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a lubricating oil blending system, which uses a mass flow meter for metering, and the feeding is more accurate. A tuning fork switch is arranged in the blending kettle and connected to a control system, which can play a role in overflow discharge.

[0005] To achieve this technical purpose, the utility model adopts the following scheme:

[0006] A lubricating oil blending system comprises a base oil tank, an oil pump, an oil pipeline, a mass flow meter, a blending kettle and a control system, wherein the base oil tank is connected to the oil pump, which is connected to the oil pipeline, a first mass flow meter and a second mass flow meter are arranged on the oil pipeline, more than two oil branch lines are connected to the oil pipeline, the oil branch line is connected to the blending kettle, and a pneumatic valve is arranged on the oil branch line; the oil pump, the first mass flow meter, the second mass flow meter and the pneumatic valve are all connected to the control system.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The utility model adopts a mass flow meter, which makes feeding more accurate. The mass flow meter corresponds to multiple blending kettles, and the construction is simple and reduces costs. The mass flow meter and the pneumatic valve are connected to the control system, and the blending kettle feeding is automatically controlled. The feeding of a blending kettle is accurately measured. After the control system starts the metering, the pneumatic valve opens, and the oil pump starts after 1 second. The material flows through the oil pipeline through the two mass flow meters. The mass flow meter measures the material flowing through. After reaching the set value A1, the oil pump stops working. After reaching the set value A2, the pneumatic valve closes and the metering is completed. The metering of other blending kettles is the same.

[0009] Furthermore, a jacket is provided outside the blending kettle, the lower part of the jacket is connected to a first pipeline, the upper part of the jacket is connected to a second pipeline, and both the first pipeline and the second pipeline are connected to the boiler; a temperature sensor is provided inside the blending kettle, a proportional regulating valve is provided on the first pipeline, the temperature sensor and the proportional regulating valve are connected to a temperature control box, and the temperature control box is connected to the control system.

[0010] Through the above settings, when the blending kettle is heating up, the temperature sensor measures the temperature of the material in the blending kettle in real time and transmits it to the temperature control box, which then feeds back to the control system. The control system automatically sends a signal to the proportional control valve through the temperature control box according to the difference between the temperature change and the set temperature value, adjusts the opening of the proportional control valve, and changes the amount of hot oil entering the jacket of the blending kettle, thereby achieving precise temperature control of the blending kettle.

[0011] Furthermore, a tuning fork switch is arranged on the cover of the blending kettle, and the tuning fork switch is connected to the control system.

[0012] Through the above settings, the blending kettle may overflow during the process of injecting materials. A tuning fork switch is installed on the upper head of the blending kettle and connected to the control system. The relevant parameters are set in the control system. During the process of injecting materials, the tuning fork switch monitors the distance between the liquid level and the tuning fork switch in real time. When the distance is equal to the system setting parameters, the control system automatically shuts down the oil pump and stops injecting materials. If oil is injected into the blending kettle filled with full materials, the system cannot be started, and the system will sound an alarm to prevent overflow.

[0013] Furthermore, an S-shaped pipe is connected to the head of the blending kettle, and an oil-water separator is arranged at the bend of the S-shaped pipe.

[0014] Through the above settings, water vapor may be discharged from the blending kettle during the heating process. By setting an S-shaped tube on the head of the blending kettle, opening a hole at the low level of the S-shaped tube to install an oil-water separator, when the steam flows through the S-shaped tube, the water vapor in the steam condenses into small water droplets when it is cold, and then enters the second half of the S-shaped tube after being collected, and finally flows into the oil-water separator. The oil-water separation collector prevents the water discharged from the material during the heating process from flowing back into the blending kettle. BRIEF DESCRIPTION OF THE DRAWINGS
