This invention discloses a device and method for evaluating the proppant-carrying performance of fracturing fluid with continuously adjustable proppant concentration, relating to the field of oil and gas field production enhancement. The device includes a reactor body. The reactor body is equipped with a stirring assembly, a proppant-adding assembly, a heating assembly, and a visualization window. The proppant-adding assembly achieves quantitative and batch-wise addition of proppant within the high-pressure reactor through a series of upper valves, a proppant-to-be-added section, and a lower valve. The method includes: applying experimental temperature and pressure conditions, initiating stirring to simulate dynamic flow, continuously adding proppant in batches through the proppant-adding assembly, monitoring the proppant status in real time using a vision system, and recording and analyzing data to obtain a continuous proppant-carrying performance curve and a limit proppant-carrying value. This invention solves the problem of existing technologies being unable to conduct continuous gradient testing of proppant concentration under high-temperature and high-pressure dynamic conditions, and can obtain complete proppant-carrying performance data of fracturing fluid from low concentration to limit concentration in one go, with evaluation results closer to actual downhole operating conditions.

The utility model discloses a portable detection device for two -way lateral flow chromatography test paper strip, including box, box cover, color developing agent drop adding mechanism, controller, camera, carousel and test paper mechanism, color developing agent drop adding mechanism, controller and camera all set up in the box, and the controller is electrically connected with camera, be equipped with detection room in the box, and the detection room is equipped with the opening in the one side of box, and the carousel rotation sets up in the detection room, and the test paper mechanism sets up on the carousel, and the camera and color developing agent drop adding mechanism all are located carousel top. The technical effect for reaching is: adopt built -in camera, and the distance, focal length of shooting some setting parameters are fixed, effectively avoid the error caused because of the difference of shooting condition, make LFIA colorimetric analysis result more accurate, be equipped with color developing agent drop adding mechanism, can realize the automatic addition of color developing agent, be convenient for positioning quantitative addition color developing agent, avoid the error caused by manual addition.

This utility model belongs to the field of pasture feeding technology, specifically providing a forage gathering device for pastures, including a moving component, a gathering component, and a supplement addition component. A first cantilever is provided on one side of the moving component, and the gathering component and the supplement addition component are respectively mounted on the first cantilever, enabling them to move forward together with the moving component. A gathering channel is formed between the two gathering plates, and the supplement addition component discharges supplement through the outlet. During the forward movement of the moving component, scattered forage enters the gathering channel formed between the two gathering plates and is gathered into strip-shaped forage stacks, achieving automatic gathering. Compared with manual pushing of forage using pushers, this method is more labor-saving and more efficient.

This utility model discloses a pipeline filter. It includes a pipe body, a rotating disk rotatably mounted in the middle of the pipe body, and filter disks rotatably mounted on both sides of the rotating disk. A reset strip is integrally provided on one side of each filter disk. An isolation mechanism is provided inside the pipe body, comprising an upper partition and a lower partition. A squeezing port is provided on one side of the upper partition, and a lifting block is provided on the edge of the rotating disk. This design divides the pipe body into two parts using the upper and lower partitions, allowing one filter disk to perform filtration while the other filter disk automatically drops dehumidifying materials vertically during rotation. After unloading, materials can be automatically added to the middle, and the filter disk can be horizontalized again during rotation, allowing it to rotate to one side of the pipe body for alternating operation. Automatic material addition is achieved without closing the ash conveying channel, and idle filter disks can be cleaned.
