Description

Technical Field

[0001] The present invention relates to the technical field of finished oil detection, and in particular to a finished oil quality detection device. Background Art

[0002] Refined petroleum products, derived from crude oil through a complex series of production and processing steps, include six major categories: petroleum fuels, petroleum solvents and chemical raw materials, lubricants, paraffin wax, petroleum asphalt, and petroleum coke. Of these, petroleum fuels dominate production, accounting for approximately 90% of total output; lubricants are the most diverse, accounting for approximately 5% of total production. Given the economic and industrial importance of refined petroleum products, countries have carefully formulated strict and detailed product standards to ensure that refined petroleum products precisely meet the technical requirements of production and the various needs of actual use.

[0003] Quality testing is a crucial component of the refined oil production chain. However, existing refined oil quality testing equipment currently has significant limitations. Most traditional testing devices are only capable of testing a single set of samples sequentially, and are unable to perform batch testing of multiple sets of samples. This means that during actual testing operations, after each set of samples is analyzed, staff must manually replace the sample. This process not only requires significant time and effort from staff, but also leaves the testing equipment idle between sample changes, significantly reducing overall testing efficiency and severely impacting production progress.

[0004] Furthermore, after the testing process is complete, some components of the previous sample set often remain on the test probe. These residual components are very likely to be mixed into the new sample system when the next set of samples is tested, thereby interfering with the accuracy of the test results and causing errors. This situation not only significantly reduces the reliability of the test data, but can also cause personnel to make inappropriate decisions based on erroneous data, causing numerous inconveniences and potential risks to the entire production process, increasing production costs and time, and posing a significant challenge to product quality control.

[0011] The present invention provides a refined oil quality detection device, which has the following beneficial effects:

[0012] 1. The present invention is provided with an intermittent rotation structure and six groups of material buckets are arranged on the rotating carrier, so there is no need to frequently replace samples. It is only necessary to start the first motor to drive the driving rotating shaft to rotate, and the driving rotating shaft drives the irregular gear to rotate.

[0013] 2. The present invention is provided with a cleaning structure. By starting the second motor to drive the screw to rotate, the screw is engaged with the screw hole on the moving belt block, but the moving belt block is limited and guided in the guide slot by the guide slider, so that the screw drives the moving belt block to move downward, so that the moving belt block inserts the detection probe into the material bucket through the recessed frame to detect the sample.

[0014] 3. The present invention is provided with an installation limit structure. By starting the electromagnet, the magnet is driven to move under the principle of opposite poles attracting each other, so that the magnet drives the rod to move, and then the insertion block at the bottom of the installation support plate is inserted into the insertion slot. Then the electromagnet is turned off. When the magnet moves, the compression spring on the outside of the connecting cross bar is squeezed to cause the compression spring to produce elastic deformation, thereby pushing the magnet to move, and then the magnet drives the rod to be inserted into the separation hole, so that the installation support plate is installed on the rotating carrier, and then the material barrel is limited with the cooperation of the limit arc plate and the limit top plate to avoid the material barrel from being offset. It is also more convenient to release the limit, thereby reducing the downtime of the equipment and improving the detection efficiency of the sample. BRIEF DESCRIPTION OF THE DRAWINGS
