Description

Technical Field

[0001] The utility model relates to the technical field of industrial silicon smelting, in particular to an automatic sampling device for industrial silicon smelting samples with irregular particle sizes. Background Art

[0002] During the acceptance inspection of raw materials for industrial silicon smelting, the particle size of raw materials such as washed clean coal, petroleum coke, and semi-coke is an important inspection standard. Particles that are too large or too small cannot meet the normal production needs of industrial silicon. At present, the analysis sampling of raw materials such as washed clean coal, petroleum coke, and semi-coke in the industrial silicon industry relies entirely on manual sampling on vehicles. The sampling range is limited to the surface of the loading vehicle compartment, resulting in insufficient representativeness of the sampling analysis, which can easily lead to disagreements in the quality acceptance of materials such as washed clean coal, petroleum coke, and semi-coke, and bring unnecessary disputes to the company's production and operation. At present, it is necessary to adopt automatic sampling by automatic sampling machines, focusing on the composition of the automatic sampling device and the process to prevent secondary force from causing material breakage, to ensure that the particle size does not undergo secondary crushing during the sampling process, and to provide an important acceptance indicator for particle size qualification rate detection;

[0003] The announcement number CN215296707U is a mobile fully automatic sampling machine, which includes a base, a column is fixedly installed on the upper side of the base, a box body is provided on the top of the column, a translation frame is fixedly installed on one side of the box body, a slider is slidably connected to the inside of the translation frame, and a screw rod is rotatably installed inside the translation frame, and the slider is threadedly connected to the screw rod, and the bottom of the slider is fixedly connected to a first electric push rod, the telescopic end of the first electric push rod is fixedly connected to a sleeve, a piercing rod is provided in the sleeve, and a middle side wall of the piercing rod is provided with several groups of feeding ports, a sampling cavity is provided inside the piercing rod and an opening is provided at the bottom, a second electric push rod is fixedly connected to the top of the sampling cavity, and the telescopic end of the second electric push rod extends out of the opening and is fixed with a baffle, which solves the problem that the pipeline is easily worn when the traditional sampling machine adopts negative pressure suction sampling, and is convenient for controlling the sample discharge after sampling;

[0004] Most of the existing sampling machines use the negative pressure of an air pump to draw samples through a pipe for sampling. The pipe is easy to get tangled when the sampling machine rotates and moves, and it is easy to wear and leak over time. The existing sampling machines are difficult to meet work needs. When the above-mentioned existing automatic sampling machine is in use, during the sampling process of the rod, the length of the translation frame is fixed and inconvenient to adjust, which leads to limited sampling positions of the rod, and then the base needs to be moved frequently, which is cumbersome to operate and reduces the efficiency of sampling. In addition, during use, the baffle needs to control the second electric push rod. Since the second electric push rod is arranged inside the rod, it occupies more internal space of the rod, reducing the sampling storage space. Therefore, corresponding improvements are needed.
