This utility model belongs to the technical field of fabric color difference detection equipment, specifically a woven fabric printing and dyeing difference detection device. It includes a detection body with an operating table inside for drying the fabric. A base is located at the bottom of the operating table, and a drive plate is slidably mounted inside the base. Multiple connecting rods are rotatably mounted on the end face of the drive plate, each connecting rod having a slider at one end. These sliders are slidably connected to the base, and clamping blocks are mounted on the outer surface of each slider. A mounting plate is slidably mounted above the operating table, and two relatively movable electric heating rollers are rotatably mounted on the bottom of the mounting plate. This utility model solves the problem of wrinkles appearing on the fabric surface during detection by using sliders and clamping blocks to fix and flatten the fabric. Simultaneously, the heating device and electric heating rollers dry the fabric, solving the problem of moisture on the fabric surface affecting the accuracy of color difference detection.

This utility model discloses a pH adjustment and treatment system for arsenic-containing wastewater, including an adjustment tank and a storage tank connected to the top of the adjustment tank by a drug inlet pipe. An inlet pipe and an outlet pipe are connected to the top of one side and the other side of the adjustment tank, respectively. A detection tube arranged in an inverted L-shape is installed inside the adjustment tank. The horizontal section of the detection tube, away from the vertical section, is connected to the inlet pipe. An outlet is located at the bottom of the vertical section. One side of the vertical section is fitted to the inner wall of the other side of the adjustment tank. A front pH meter with a probe inserted into the vertical section of the detection tube is detachably connected to the adjustment tank. A middle pH meter and a rear pH meter with probes located inside the adjustment tank and separated by a second filter screen are detachably connected sequentially at the top and rear of the adjustment tank. The middle pH meter is covered by a cleaning component and a bottom cover. A lifting mechanism for driving the cleaning component to rise and fall is installed on the top of the adjustment tank. An opening for the first filter screen is located at the top of the bottom cover. The system offers high overall adjustment accuracy, long probe lifespan, and easy probe disassembly, replacement, and cleaning.

The utility model provides a kind of superfast detection device of fluorescent quantitative polymerase chain reaction, it is related to molecular biology detection technical field, including: casing, the bottom position of the one side of the casing and the inside position of casing are equipped with firm plate respectively, the firm plate of bottom is equipped with first electric motor on one side, the bottom position of the firm plate of inside is equipped with third electric motor, the bottom position of casing is equipped with locating sleeve on the other side.Electric motor driven stirring sleeve simultaneously, synchronously stirs a group of reaction test tube, makes fluorescent quantitative polymerase chain fully mix in reaction test tube, the inside of stirring sleeve is provided with detection rod and the reaction of fluorescent quantitative polymerase chain is rapidly detected, the setting of an electric motor simplifies the drive structure and energy consumption of a group of stirring sleeve, detection rod, solves the problem that traditional integration structure is poor in adaptability, maintenance is complicated.

The utility model relates to a kind of fine grinding diameter automatic detection measuring machines, including pedestal;It is used for supporting product to be arranged at the center of pedestal support assembly;Detection mechanism is measured to product;Respectively arranged in the both ends of detection mechanism: driving mechanism for driving product rotation, including stepper motor, driven wheel driven by stepper motor, transmission wheel transmission connection with driven wheel by belt, the driven wheel is fixedly connected with limit board, and first centre is equipped with driven wheel coaxial on limit board;For clamping product clamping mechanism, including clamping cylinder, ejector rod driven by clamping cylinder, sliding table pushed by ejector rod, second centre is equipped for resisting product on the sliding table;The first centre and second centre cooperate clamping product and drive its rotation.Solve the conventional roundness and diameter detection need worker manual operation monitoring equipment to detect, leading to detection precision is poorer, the problem of low detection efficiency.
