This utility model discloses a treatment system for recovering industrial-grade sodium chromate from chromium-containing electroplating wastewater. The system is sequentially connected to a pretreatment system, an ion exchange system, an evaporation and concentration system, a purification system, and an evaporation and crystallization system. The pretreatment system removes suspended solids. The ion exchange system contains at least four ion exchange columns and an eluent tank; the coordinated operation of multiple columns ensures sufficient adsorption and elution of chromium, increasing the concentration of hexavalent chromium in the eluent, reducing the load on subsequent evaporation equipment, and shortening processing time. The evaporation and concentration system uses an MVR evaporator and integrates an online density meter. The purification system is equipped with a purification reaction vessel with a detachable pH meter probe, which can quantitatively remove sulfate, reducing the difficulty of salt separation and crystallization, increasing the number of mother liquor circulations, and thus improving the chromium recovery rate. The feed to the eluent tank allows for reasonable adjustment of the alkali dosage according to different concentrations of components, avoiding waste and reducing costs. The detachable pH meter probe facilitates maintenance, ensures accurate monitoring, and improves the stability of sulfate removal rate and the quality of sodium chromate products.

This invention discloses an improved AG fixture, comprising: a fixture body, a storage space adapted to hold glass, an upper surface of the fixture body being a first plane, a bottom surface of the storage space being a second plane, the first plane being located above the second plane, and glass adapted to be placed in the storage space being positioned between the first and second planes. The glass has protrusions, the upper surfaces of which protrude beyond the first plane. This invention effectively prevents glass displacement and chipping during processing, structurally avoids localized etching anomalies, reduces color defects and glass damage, ensures continuous and stable processing, and, in conjunction with fixture structural optimization, forms a synergistic effect, solving the problem of chemical waste in existing technologies, while improving product yield and reducing overall production costs.

The application discloses a sample adding device, a needle lifting method thereof and a sample analyzer. The sample adding device comprises a sampling needle, a first driving member and a controller. The sampling needle is used for sucking / discharging liquid. The first driving member is connected with the sampling needle and is used for driving the sampling needle to move. The controller is connected with the first driving member and is used for controlling the first driving member to drive the sampling needle to move upwards after the sampling needle sucks / discharges liquid, so that the speed of the sampling needle before the sampling needle is separated from the liquid surface is not greater than a preset speed. The preset speed is obtained based on the overall needle lifting rate of the sampling needle and the speed corresponding to the liquid droplet shape in which the liquid film on the surface of the sampling needle is not gathered. After the sampling needle is separated from the liquid surface, the first driving member drives the sampling needle to accelerate upwards, so that the speed of the sampling needle reaches a speed threshold. The speed threshold is greater than the preset speed. The sample adding device can improve the accuracy and repeatability of sample adding and can also improve the efficiency of sample adding.
