Problems solved by technology
Although the compression method and centrifugation method have been widely used, most of the methods are manual operations. As far as the compression extraction method is concerned, different extrusion forces may cause structural changes in the oil-absorbing material, thereby affecting the accuracy of its reusability performance test; Whether the record of oil volume change is continuous during the test will also affect the accuracy of the performance test, so the automatic compression extraction of the test device also needs to be solved urgently

Embodiment
[0047] Taking the modified ramie fiber as an example, weigh about 0.1g of the modified ramie fiber sample and place it on the support partition in the deoiling tank. The computer labview software system controls the crude oil tank to transport 100ml (crude oil) to the deoiling tank. In the oil tank; close the switch baffle of the crude oil tank so that the crude oil is in full contact with the oil absorption material in the deoiling tank for about 10 minutes to complete the saturation experiment; use the LabVIEW software system to open the oil drain hole of the support partition under the deoiling tank to drain the oil About 30s; then the computer LabVIEW software system controls the piston-type de-oiling compression mechanism to extrude the oil-absorbing material and repeatedly compress until the difference between the weight of the first weight and the weight of the previous one is less than 5% after the electronic balance with the oil container is placed. Record the total pre...

The invention provides an automatic detection device of an oil absorption material repeating utilization ratio. The device comprises a crude oil supply system for continuously providing crude oil for determination of a repeating utilization ratio of an oil absorbing material, an oil suction material extrusion system which is in communication with the crude oil supply system and is used for compression of the oil absorbing material and extraction of oil in the oil absorbing material, an automatic weighing system for weighing oil produced before and after oil absorbing material compression and transmitting data to a data acquisition and control analysis system for continuous recording, and the data acquisition and control analysis system which is connected to the crude oil supply system, the oil absorbing material extrusion system and the automatic weighing system, records and reads the data in the automatic detection device and controls work of the automatic detection device. The automatic detection device utilizes the extrusion device to realize automatic compression and extraction in an oil absorbing material repeating utilization ratio test, prevents the error caused by the man-made operation, is convenient to carry out quality management and control based on an experiment personnel, and provides technical guarantee for the determination of the repeating utilization ratio of the oil absorbing material.
Description
Technical field [0001] The invention belongs to the technical field of oil-absorbing materials and environmental protection, and in particular relates to an experimental device for testing the repetition rate of oil-absorbing materials and a testing method using the device. Background technique [0002] In recent years, crude oil leakage accidents at home and abroad have severely damaged the ecological environment system, and various treatment measures have emerged. The adsorption of oil-absorbing materials is one of the main means of oil spill treatment. A good oil-absorbing material should have the characteristics of strong hydrophobicity, fast oil absorption, large oil absorption, no sedimentation after oil absorption, recyclable and environmentally friendly. In the determination of various properties of oil-absorbing materials, the identification of the oil-retaining properties of oil-absorbing materials is a very important link. [0003] At present, although there are many in...
