The invention discloses triaxial test equipment for measuring eroded soil particles under the action of seepage force. The equipment comprises a constant-flow seepage system, a soil particle migration grading measurement system, a large-range volume pressure control vacuum system and a data processing analysis system; the constant-flow seepage system is connected with the soil particle migration grading measurement system and the large-range volume pressure control vacuum system through pipelines; and the data processing analysis system comprises a data acquisition device and a computer; the constant-flow seepage system, the soil particle migration grading measurement system and the large-range volume pressure control vacuum system are connected to the data acquisition device through lines; and the computer is connected with the data acquisition device through a line. Simulation and dynamic observation of the erosion phenomenon of a soil sample under the action of specific seepage force are achieved, and an accurate and effective basic test data is provided for research on the disaster-causing mechanism of geological disasters corresponding to the erosion phenomenon.

The invention discloses a magnetic suspension composite window with the air purifying function. The magnetic suspension composite window comprises a window frame, an outer window sash and an inner window sash. A flexible connecting frame is mounted on the covered edge of the periphery of the window frame. Electromagnetic strips are embedded in the covered edge of the periphery of the window frame, a peripheral frame of the inner window sash and a peripheral frame of the outer window sash. A hidden screen window is arranged on the right side of the window frame and comprises a screen shaft, a window screen and a winding device. The window screen is made of a nanometer air filtering material. A conveying mechanism doing horizontal reciprocating motion is mounted at the top of the inner window sash and comprises a drive motor, a gear and a rack. By the adoption of the magnetic suspension composite window with the air purifying function, on the one hand, the sealing effect of the window is enhanced, and the remarkable anti-theft function is achieved; on the other hand, air is completely filtered, and the higher air purifying effect is achieved; the magnetic suspension combined window is a novel product which integrates the anti-theft function, the mosquito prevention function, the air purifying function and the self-cleaning function, full-automatic control can be achieved, the requirements of current various high-end smart home furnishing can be met, and the good economic value and social value are achieved.

The invention relates to a cutting fluid purification method which comprises a bottom plate, a shell frame, a filtering device and a demagnetizing device. The shell frame is mounted at the upper end of the bottom plate, the section of the shell frame is of a U-shaped structure, the filtering device is mounted at the upper end of the interior of the shell frame, and the demagnetizing device is arranged below the filtering device and is mounted at the lower end of the interior of the shell frame. According to the present invention, the problems that when an existing device is used for filteringthe cutting fluid, the filtering effect is poor; and the filtering is incomplete; generally, a large amount of metal waste is mixed in the filtered filtrate, so that the subsequent treatment of the filtrate is influenced; meanwhile, the filter residues cannot be cleaned rapidly, so that the filtering efficiency is influenced; moreover, when the magnetic metals in waste liquid are removed, the removed metal impurities cannot be cleaned and collected effectively, so that the metal impurities cause the secondary pollution to the cutting fluid, and the use effect of the cutting fluid is influenced, etc., can be solved.

The invention discloses an industrial waste gas automatic filtering and cleaning device, comprising a filter box, a processor is fixed on one side of the outer wall of the filter box by bolts, and an air outlet pipe is fixed by bolts on the outer wall of one side of the filter box, and the air outlet pipe is located in the processor Below, one side of the outer wall of the air outlet pipe is fixed with a detection box by bolts, the inner wall of one side of the filter box is fixed with a first water pump by bolts, and one end of the water inlet of the first water pump is welded with a first conduit, the first water pump is welded. One end of the water outlet of a water pump is welded with a second conduit, and the second conduit is welded with an inner wall of one side of the filter box. The invention can effectively settle the waste gas, so that the large-particle impurities in the waste gas can be deposited and electrolyzed, and at the same time, the settled waste gas flows into the third conduit, avoiding the use of chemicals for neutralization, and at the same time, the electrolyte can be recycled to avoid waste of resources. , improve the energy saving and environmental protection of the device, can effectively filter the exhaust gas, and make the exhaust gas filtration more complete.
