Metering detection device for liquid taking metering

Abstract

The invention discloses a metering detection device for liquid taking metering and belongs to the technical field of liquid metering devices. The metering detection device for liquid taking metering comprises a measuring cylinder, wherein a piston plate is slidably connected in the measuring cylinder, the top of the piston plate is fixedly connected with a first connecting rod, a rack is fixedly connected with the support, the measuring cylinder is fixedly connected with a fixing frame, a worm is rotationally connected into a fixed frame, a worm wheel is rotationally connected with the fixed frame, a supporting rod is rotationally connected into the piston plate, stirring blades are fixedly connected with one end of the support rod at the bottom of the piston plate, a hollow column is rotationally connected with the support, a limiting strip is fixedly connected with the supporting rod, a rotating shaft is rotationally connected into the piston plate, an exhaust plate is fixedly connected with the bottom of the rotating shaft, a first exhaust hole is formed in the exhaust plate, a second exhaust hole is formed in the piston plate, and the first exhaust hole communicates with the second exhaust hole. The metering detection device is advantaged in that a large amount of liquid can be measured conveniently, and the stirring blades rotate to stir the solution in the extraction andrelease process, so precipitation is avoided.

Description

technical field [0001] The invention relates to the technical field of liquid metering devices, in particular to a metering and detecting device for liquid taking and metering. Background technique [0002] At present, in the chemical industry, such as food industry, pharmaceutical industry and textile dyeing industry, liquid chemicals are often used. These chemicals need to be used according to the set ratio to achieve the target effect of the chemical reaction. Fast and accurate measurement has always been a topic of great concern to the relevant industries. [0003] When conducting research, in order to ensure the accuracy of the research, a fixed amount of liquid needs to be taken out. Generally, when measuring these liquids, it is necessary to pass through test tubes, beakers, and containers with scales. However, if the amount of liquid taken out is large, through The measurement of these containers will be cumbersome. In addition, in order to avoid the precipitation o...

[0003] When conducting research, in order to ensure the accuracy of the research, a fixed amount of liquid needs to be taken out. Generally, when measuring these liquids, it is necessary to pass through test tubes, beakers, and containers with scales. However, if the amount of liquid taken out is large, through The measurement of these containers will be cumbersome. In addition, in order to avoid the precipitation of liquid (such as color material) in the bottle, the previous practice is to put a magnet in the storage bottle, and cooperate with external parts to drive the magnetic positive and negative poles to change to store. The magnet in the bottle is rotated by magnetic force, so that the magnet can generate proper stirring action on the internal liquid, so as to avoid the problem of uneven precipitation of the liquid in the storage bottle. Purpose, but each storage bottle requires a magnetic positive and negative rotation device, which will increase the cost of the device
