Description

Technical Field

[0001] The utility model relates to the technical field of moisture analyzers, and specifically relates to a moisture analyzer with automatic sample injection. Background Technique

[0002] A moisture analyzer is an instrument that can detect the moisture content in various organic and inorganic solids, liquids, gases and other samples. According to the measurement principle, it can be classified into two major categories: physical measurement methods and chemical measurement methods. Commonly used physical measurement methods include weight loss method, distillation stratification method, gas chromatography analysis method, etc. Chemical measurement methods mainly include Karl Fischer method, toluene method, etc. The International Organization for Standardization has designated the Karl Fischer method as the international standard for measuring trace moisture, and our country has also designated this method as the national standard for measuring trace moisture.

[0003] Ordinary moisture analyzers usually do not have the function of automatic sample injection. When using an ordinary moisture analyzer, the operator needs to manually take a sample solution and then add it to the moisture analyzer for detection. Such a process flow is relatively cumbersome, resulting in inconvenient operation. Therefore, a moisture analyzer with automatic sample injection is proposed to solve the above-mentioned problems. Content of the Utility Model

[0004] (I) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a moisture analyzer with automatic sample injection, which has the advantages of automatic sample injection, etc., and solves the problem that when using an ordinary moisture analyzer, the operator needs to manually take a sample solution and then add it to the moisture analyzer for detection, and such a process flow is relatively cumbersome, resulting in inconvenient operation.

[0006] (II) Technical Solutions

[0007] The technical solution of the utility model to solve the above technical problems is as follows: A moisture analyzer with automatic sample injection includes a moisture analyzer body. Four support columns are fixedly connected to the top of the moisture analyzer body and are distributed in a rectangular array. The same housing is fixedly connected to the tops of the four support columns. An electric push rod is fixedly connected to the left inner wall of the housing cavity. A pull rod is fixedly connected to the right side of the electric push rod. A piston is fixedly connected to the right side of the pull rod. The piston is slidably connected to the outside of a sleeve. Two connecting rods are fixedly connected to the top of the sleeve and are distributed symmetrically left and right. The tops of the two connecting rods are fixedly connected to the top wall of the housing cavity. A liquid inlet hole is opened inside the sleeve. A three-way pipe is fixedly connected to the right side of the sleeve. The liquid inlet hole is communicated with the three-way pipe. A first one-way valve is arranged at the input end of the three-way pipe. A second one-way valve is arranged at the output end of the three-way pipe. A sampling pipe is communicated with the right side of the three-way pipe. A liquid delivery pipe is communicated with the bottom of the three-way pipe. The liquid delivery pipe is connected to the moisture analyzer body.

[0008] The beneficial effects of the present utility model are as follows: The electric push rod drives the piston to move through the pull rod. The piston cooperates with the sleeve to suck the three-way pipe. The three-way pipe sucks the solution through the sampling pipe. When the three-way pipe sucks the solution, the first one-way valve is in an open state to facilitate the suction of the three-way pipe, and the second one-way valve is in a closed state to prevent the solution from directly entering the liquid delivery pipe. After the solution enters the sleeve through the three-way pipe and the liquid inlet hole, the suction is completed. The electric push rod drives the piston to move through the pull rod. The piston cooperates with the sleeve to squeeze the solution in the sleeve into the three-way pipe. When the solution is squeezed out, the first one-way valve is in a closed state to prevent the solution from being squeezed out through the sampling pipe, and the second one-way valve is in an open state, facilitating the solution to be squeezed out from the three-way pipe and enter the moisture analyzer body through the liquid delivery pipe for detection.

[0009] This moisture analyzer with automatic sample injection has the advantages of automatic sample injection.

[0011] Further, a detection probe is arranged inside the three-way pipe, and an indicator light adapted to the detection probe is arranged at the top of the housing.

[0012] The beneficial effect of adopting the above further solution is that the detection probe facilitates detecting the solution inside the three-way pipe.

[0013] Further, an observation window is arranged on the front of the housing, and the observation window is adapted to the sleeve.

[0014] The beneficial effect of adopting the above further solution is that the observation window facilitates observing the extraction amount of the solution in the sleeve.

[0015] Further, a control panel is arranged on the front of the moisture analyzer body, and the control panel is adapted to the electric push rod.

[0016] The beneficial effect of adopting the above further solution is that the control panel facilitates observing the suction data.

[0017] Further, the bottom of the moisture analyzer body is fixedly connected with four connecting blocks distributed in a rectangular array, and support feet are threadedly connected inside the four connecting blocks.

[0018] The beneficial effect of adopting the above further solution is that the four support feet can provide a supporting effect for the moisture analyzer body through the four connecting blocks.

[0019] Further, two fixing rings are fixedly connected to the top wall of the inner cavity of the housing and are distributed symmetrically left and right. The inner sides of the two fixing rings are fixedly connected to the outer side of the electric push rod.

[0020] The beneficial effect of adopting the above further solution is that the two fixing rings can provide further fixing effect for the electric push rod through the housing. Brief Description of the Drawings
