Description

Technical Field

[0001] The invention relates to the technical field of chemical detection, in particular to an impurity analysis instrument for chemical detection. Background Art

[0002] Chemical impurities refer to foreign substances that are not intentionally added but inevitably appear during the production, processing, storage and transportation of chemical products and affect the quality or performance of the product.

[0003] After searching the Chinese patent with publication number CN113138112A, an impurity analysis instrument for chemical detection is disclosed, which relates to the field of chemical detection technology, specifically an impurity analysis instrument for chemical detection, including an analyzer housing, a support foot is fixed at the bottom of the analyzer housing; a display screen, which is embedded in the outer wall of the analyzer housing; a feed pipe, which is arranged above the analyzer housing, and a quantitative box is connected above the feed pipe, and the feed pipe and the quantitative box are interconnected; a metal detection head, which is fixedly arranged on the outer wall of the feed pipe; and an analysis box. The impurity analysis instrument for chemical detection is provided with a quantitative box. By opening the protective cover, industrial impurities are put into the quantitative box. Under the action of the scale, the industrial impurities in the quantitative box can be conveniently observed. After the appropriate amount is put in, the protective cover is closed, thereby playing a quantitative function, avoiding the inability to accurately obtain the required detection data due to excessive industrial impurities, and having strong practicality.

[0004] However, the above invention has the following disadvantages: Although the above device can achieve the effect of quantitative detection of chemical impurities, during detection, since the impurities are generally located inside the solution, some impurities are insoluble and some impurities are soluble, this makes it impossible for the impurities to be evenly distributed inside the solution. In addition, in the above technology, the analysis probe is only set on one side inside the analysis box, and thus during analysis, the analysis probe cannot evenly contact the impurities, which will lead to inaccurate detection results.

[0015] The present invention provides an impurity analysis instrument for chemical detection by improvement, which has the following improvements and advantages compared with the prior art: First, in the present invention, after the solution falls into the mixing bin, the first motor can be started, and the first motor drives the stirring blade to rotate through the stirring rod. The rotation of the stirring blade can stir the solution, so that the impurities in the solution can be evenly distributed inside the solution. After the solution inside the mixing bin is evenly mixed, the solution can be sent into the discharge pipe. When the solution flows inside the discharge pipe, the detector can perform impurity analysis on the solution flowing inside the discharge pipe through the detection head, and the analysis result can be displayed on the display screen, thereby achieving the effect of evenly distributing the impurities inside the solution, thereby ensuring the accuracy of the detection result.

[0016] Secondly, through the setting of the collecting mechanism, the present invention can ensure that when all the solutions in the mixing bin flow into the discharge pipe, the metal products will remain in the mixing bin. Since the first motor is a forward and reverse motor, when the first motor drives the stirring rod to drive the stirring blades to rotate clockwise in the mixing bin, the stirring blades can squeeze the blocks, and the blocks can be retracted back into the movable groove. At this time, the sealing plate will not move. When it is necessary to collect the metal products, the first motor can drive the stirring blades to rotate counterclockwise in the mixing bin. When the stirring blades rotate counterclockwise, the contact between the stirring blades and the blocks will prevent the blocks from retracting into the movable groove. At this time, the sealing plate will be subjected to the squeezing force and flipped inside the discharge port. The metal products in the mixing bin can fall into the metal collection box through the discharge port and be collected, thereby achieving the effect of automatically collecting the metal products.

[0017] Third: In the present invention, after the solution is discharged and the detection is completed, the air pump can be started, and the air pump can inject air into the interior of the feed pipe through the air pipe. After the air enters the interior of the mixing bin, the pressure inside the mixing bin will increase, so that the solution can completely enter or leave the interior of the discharge pipe, thereby achieving the effect of complete discharge.

[0018] Fourthly, the present invention is provided with a steering mechanism. When the solution is discharged, the drain pipe is located at the opening position on the solution collection box. When cleaning, the second motor can be started. The second motor drives the driving gear to rotate through the rotating shaft. The two driving gears are meshed with the transmission gear ring, so that the movable bin will drive the drain pipe to move. After the drain pipe moves to the other end inside the limit seat, the drain pipe is located at the opening position on the waste water tank. At this time, the cleaned waste water discharged from the discharge pipe can be collected by the waste water tank, thereby achieving the effect of facilitating the cleaning of the mixing bin and the discharge pipe while facilitating the collection of waste water.
