Description

Technical Field

[0001] The utility model relates to the technical field of sampling of reaction kettles, in particular to a sampling device for solid-liquid mixed samples of a reaction kettle. Background Art

[0002] During the production process using reaction kettles in fields such as metallurgy and chemical industry, it is often necessary to sample and analyze the materials in the reaction kettle to judge the reaction process.

[0003] In the existing sampling process of reaction kettles, sampling often requires stopping stirring, which increases the complexity of the operation. Moreover, when the stirring stops running, the materials are likely to settle, resulting in inaccurate liquid-solid ratios of the obtained solid-liquid mixed samples. Sampling bottles are usually made of glass or polymer materials, which are easy to break and easy to contaminate the slurry in the kettle. Summary of the Utility Model

[0004] The purpose of this solution is to provide a sampling device for solid-liquid mixed samples of a reaction kettle to solve the problem that the liquid-solid ratio of the solid-liquid mixture sample is inaccurate due to the need to stop the stirring operation during sampling of the reaction kettle.

[0005] To achieve the above purpose, this solution provides a sampling device for solid-liquid mixed samples of a reaction kettle, including a reaction kettle and a sampling device for solid-liquid mixed samples of the reaction kettle. The sampling device for solid-liquid mixed samples of the reaction kettle is provided with an automatic rope retractor, the automatic rope retractor is equipped with a sampling rope, the sampling rope is connected to a sampling device connecting rod, the connecting rod is connected to the upper trunnion of a double-cone stainless steel sampler, the double-cone stainless steel sampler is positioned on a fixed rod through a positioning ring, and the fixed rod is fixed to the inner wall of the reaction kettle through a fixing ring. A sample outlet valve is provided at the lower part of the stainless steel double-cone sampler. The automatic rope retractor consists of a sampling rope reel, a rope retracting frequency conversion motor, and a rope retracting motor control component.

[0006] The principle of this solution is as follows: During the reaction process of the reaction kettle, if intermediate sampling is required, without stopping the stirring of the reaction kettle, lower the sampling rope. The stainless steel double-cone sampler sinks below the liquid level along the fixed rod by using the motor rotation, its own gravity, and the conical design to sample the solid-liquid mixed sample.

[0007] The technical effect of this solution is as follows: This solution realizes non-stop sampling of the liquid-solid mixed materials, which not only ensures that sampling does not affect production but also ensures the accuracy of the liquid-solid ratio of the sample.

[0008] Furthermore, the depth of the sampler entering the reaction kettle can be adjusted by adjusting the sampling rope to adapt to problems such as the difficult control of the liquid level in the reaction kettle.

[0009] Furthermore, the stainless steel double-cone sampler is fixed to the fixed rod through a positioning ring, which can avoid contact with the stirring and prevent the sampling rope from getting entangled.

[0010] Further, the sampling bottle is made of double - cone stainless steel, acid - and alkali - resistant. It enters the liquid surface for sampling by its own gravity and the bottom conical design. The upper frustum design can prevent the sample from spilling during the lifting process. The bottom cone and the sample outlet valve design facilitate the transfer of the sample. BRIEF DESCRIPTION OF THE DRAWINGS
