This invention relates to the field of mercerizing machine wastewater treatment technology, specifically a multi-stage membrane separation treatment device for mercerizing machine wastewater, comprising: a centrifugal filtration assembly, a pressurizing assembly, and a multi-stage membrane filtration assembly arranged sequentially from the inside out; the centrifugal filtration assembly includes a centrifugal filter drum and filter cake conveying spiral blades arranged on the inner wall of the centrifugal filter drum and rotating with the centrifugal filter drum, so that the filter cake is conveyed and discharged by the filter cake conveying spiral blades. This invention utilizes the relative rotation between the centrifugal filter drum and the filter cake conveying spiral blades to allow the filtrate to penetrate the centrifugal filter drum and enter the area between the centrifugal filter drum and the storage pipe. The filter cake, due to the relative rotation between the centrifugal filter drum and the filter cake conveying spiral blades, is finally discharged from the guide hopper. Simultaneously, the filtrate sequentially passes through a microfiltration membrane cartridge, an ultrafiltration membrane cartridge, and a reverse osmosis membrane cartridge, improving the filtration effect of the water and preventing unstable water quality after filtration.

The connecting mechanism on the segmentable ladder elbow joint frame one improves the convenience and stability of segmentation, meeting the user's need for flexible adjustment of the ladder length in different scenarios.

The utility model relates to lotus storing device technical field discloses a kind of storing devices for picking fresh lotus, including main frame, telescopic frame one and telescopic frame two;The inside of the frame of main frame is equipped with telescopic cavity one, the inside of telescopic frame one is movably connected in telescopic cavity one, the inside of telescopic frame one is equipped with telescopic cavity two, and the inside of telescopic frame two is movably connected in telescopic cavity two;The side of main frame is provided with limit component, and the application can effectively expand the volume on the basis of original main frame, realize that one main frame stores more fresh lotus, through the convenient adjustment of the volume of main frame, both can realize the storage of small amount of fresh lotus, also can realize the storage of more fresh lotus, and less main frame is more convenient when carrying, and the space occupied is also less, it is extremely convenient to use on picking boat.

This invention relates to the field of partition wall panel construction technology, and discloses a lightweight partition wall panel construction, installation, and lifting device and method with positioning calibration. The device includes a base frame and traveling wheels fixedly installed around the bottom of the base frame. A mounting frame is fixedly connected to one side of the top of the base frame. Side grooves are opened on both sides of the mounting frame. A movable seat is slidably installed inside the mounting frame. A positioning calibration component is provided on one side of the movable seat. Lifting components are provided on both sides of the base frame. The lifting components include internal racks fixedly connected to both sides of the movable seat. Gears are rotatably connected inside the side grooves. By setting up the lifting components, it is easy to adapt to changes in the height of the center of gravity, and to allow for autonomous adjustment and sequential unfolding of the extension plates. Thus, the higher the center of gravity, the more stable the lifting device becomes. When the movable seat is lowered and reset, the extension plates will also automatically and slowly retract and reset sequentially, avoiding instability of the lifting device caused by rapid reset, and further improving the stability of the partition wall panel lifting.

This utility model provides an auxiliary device for hot pressing and shaping plywood, relating to the field of plywood production technology. It includes a hot pressing chamber, with a hot pressing and shaping auxiliary component installed on the outside of the chamber. This auxiliary component includes a polymerization frame installed on the outside of an upper frame, with polymerization hydraulic pump rods installed at both ends of the polymerization frame, and four corner clamps installed at the ends of the polymerization hydraulic pump rods. Using this auxiliary device, the plywood is placed on a lower extrusion pressing plate flush with the surface of the hot pressing chamber. Simultaneously, the polymerization hydraulic pump rods outside the polymerization frame push the four corner clamps inward to tighten, forming a stable four-sided support, thereby aligning the four corners of the plywood and preventing unstable force during extrusion. When the upper and lower extrusion pressing plates are pressing the plywood in the hot pressing chamber, a heat dryer is activated, and hot air is evenly sprayed from the nozzles to ensure uniform heating of the plywood and accelerate glue curing.

This invention discloses a terahertz super-resolution imaging method for defects in terahertz polyethylene pipe thermofusion joints based on CBAM-ESRGAN, comprising the following steps: Step 1, automatically acquiring detection images using a terahertz feature parameter imaging method, preprocessing the images to obtain high-resolution and low-resolution images for model training, and dividing them into training and test sets in a 7:3 ratio; Step 2, inputting the training set from Step 1 into the CBAM-ESRGAN network for training. The beneficial effect of this CBAM-ESRGAN-based terahertz super-resolution imaging method for defects in terahertz polyethylene pipe thermofusion joints is that it provides an efficient super-resolution reconstruction method for defects in polyethylene pipe pores. From terahertz imaging to the construction of a super-resolution deep learning model, a complete defect detection system is formed, effectively solving the problems of low acquisition efficiency and blurred edges in terahertz imaging of defects in polyethylene pipe pores.
