Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lubricating oil production, in particular to a lubricating oil production and filling 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, various additives for producing lubricating oil are added to the blending kettle separately, which takes a long time and has a low degree of automation. In addition, in the finished product filling process, there is generally a one-to-one correspondence between the filling pump and the filling machine. When the filling pump fails, the corresponding filling machine will stop, which is not conducive to continuous production. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a lubricating oil production and filling system, which first mixes additives into compound additives in an additive tank and then mixes them with base oil to generate finished products, thereby avoiding multiple additions during production.
[0005] To achieve this technical purpose, the utility model adopts the following scheme:
[0006] A lubricating oil production and filling system comprises a base oil tank, a blending kettle, a finished product tank, a filling machine and a control system, wherein the base oil tank is connected to an oil delivery pump, the oil delivery pump is connected to a blending kettle feed port, a first mass flow meter is arranged between the oil delivery pump and the blending kettle, the blending kettle feed port is also connected to an additive tank, a second flow meter is arranged between the blending kettle and the additive tank; the blending kettle discharge port is connected to the finished product tank, the finished product tank discharge port is connected to the filling machine, a filling pump is arranged between the finished product tank and the filling machine, the filling pump is connected to a low-pressure control cabinet, and the low-pressure control cabinet, the filling machine, the oil delivery pump, the first mass flow meter, and the second flow meter are all connected to the control system.
[0007] Compared with the prior art, the beneficial effects of the present invention are:
[0008] The utility model arranges an additive tank before the blending kettle, blends the additive into a compound additive in the additive tank, and then blends the additive with the base oil to generate a finished product, thereby avoiding multiple additions during production.
[0009] Furthermore, the number of filling pumps is greater than the number of filling machines, and the filling pumps are arranged in parallel.
[0010] Through the above settings, the filling machine and the filling pump are linked for filling. Select the filling machine and filling pump on the control panel of the control system, and click the start button to automatically run the system. After the filling machine is started, it sends a signal to the control system through the control cable. The control system receives and processes the signal and sends a start signal to the low-voltage control cabinet. The filling pump starts and supplies materials to the filling machine to achieve linked filling. If multiple filling pumps and filling machines are set, the linked filling pumps and filling machines can be selected through the control system. When one of the filling pumps fails, it will not affect the use of other filling pumps, ensuring continuous filling.
[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. BRIEF DESCRIPTION OF THE DRAWINGS
