Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen determination instruments for protein detection, in particular to a nitrogen determination instrument for protein detection. Background Art

[0002] A nitrogen analyzer is a specialized instrument for detecting nitrogen content in seeds, dairy products, beverages, feed, soil, and other agricultural and sideline products. Based on the principle that the nitrogen content in protein is constant, the nitrogen analyzer calculates the protein content by measuring the nitrogen content in the sample. Because the method used to measure and calculate protein content is called the Kjeldahl method, it is called a Kjeldahl nitrogen analyzer, also known as a protein analyzer or crude protein analyzer. This instrument is widely used in food factories, pharmaceutical testing, and fertilizer testing. Existing nitrogen analyzers for protein testing require distillation of the sample digestion tube during use. During installation, the high surface temperature of the digestion tube makes it inconvenient to remove the digestion tube, affecting the efficiency of the test. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model provides a nitrogen analyzer for protein detection, which solves the problem that the sample digestion tube of the existing protein detection nitrogen analyzer needs to be distilled during use, and the surface temperature of the digestion tube is high when the digestion tube is installed, which makes it inconvenient to remove the digestion tube, thereby affecting the efficiency of detection.

[0006] Preferably, an operation button is fixedly connected to the upper end of the nitrogen analyzer body, the digestion tube tray is arranged below the installation groove, and the triangular flask tray is arranged below the condensate tube and the absorption liquid tube.

[0007] Preferably, the diameter of one end of the fixing groove is larger than the other end, and the telescopic spring is clamped at the end of the fixing groove with the larger diameter for fixation.

[0008] Preferably, one end of the telescopic rod is provided with an inclined surface, and the bottom of the inclined surface is fitted on the top of the stopper.

[0009] Preferably, a bump is raised on the bottom of the slider, a slot is recessed on the top of the stopper, and the slider is engaged with the inside of the slot via the bump.

[0010] Preferably, the fixing bolts are fixedly connected to both ends of the mounting groove.

[0011] Preferably, a digestion pipe is clamped inside the installation groove, and the connecting piece is fixedly connected to both ends of the digestion pipe.

[0012] The utility model provides a nitrogen analyzer for protein detection. Compared with the existing technology, it has the following advantages:

[0013] 1. A nitrogen analyzer for protein detection is used. The digestion tube is clamped into the installation groove through the connectors fixed at both ends of the digestion tube. At the same time, the blocks fixed at both ends of the installation groove are first clamped into the interior of the connection groove. The telescopic rod contracts toward the interior of the connector due to the squeezing action of the block. When the top of the block enters the interior of the connection groove, the telescopic rod is clamped to the top of the block under the resetting action of the telescopic spring. The telescopic rod continues to slide upward on the outside of the slider, and then downward so that the protrusion at the bottom of the slider is embedded in the interior of the card slot. At this time, the telescopic rod can slide outside the slider and the block, and the digestion tube is detached from the interior of the installation groove, making the disassembly and assembly of the digestion tube more convenient.

[0014] 2. The nitrogen analyzer for protein detection can install the digestion tube into the installation groove by sliding the slider on the outside of the slide rod. The digestion tube can be removed from the installation groove without complicated operations. At the same time, a spring is provided inside the digestion tube tray to amplify the operating distance of the digestion tube in the vertical direction, avoiding the digestion tube tray from hindering the installation of the digestion tube.
