Description

Technical Field

[0001] This utility model relates to the field of material sampling and inspection technology, specifically a mixed material sampling and testing tool. Background Technology

[0002] For aluminum alloy production enterprises, material sampling is classified into full inspection and spot inspection. Most aluminum alloy production enterprises mainly rely on spot inspection for bagged materials. The existing technology for spot inspection of bagged materials generally uses sampling probes to sample the upper, middle and lower areas of the bagged material. After sampling, the composition of different particle sizes of the material in the sampling probe is determined.

[0003] Existing sampling probes cannot separate materials of different particle sizes after sampling. For workers with certain professional knowledge and experience, the composition of different particle sizes in the material can be determined by directly observing the material inside the sampling probe with the naked eye. However, there is also the problem of inaccurate visual observation leading to errors in the interpretation of the composition of different particle sizes in the material. For general workers, it is necessary to use tools such as sieves to perform secondary classification of the material inside the sampling probe in order to determine the composition of different particle sizes in the material. Utility Model Content

[0004] The purpose of this invention is to provide a mixed material sampling and testing tool that can separate materials of different particle sizes without the need for secondary classification using tools such as sieves after sampling, thereby improving the accuracy of bagged material sampling and testing, effectively reducing manual labor intensity, and increasing the efficiency of bagged material sampling and testing.

[0005] To achieve the above-mentioned technical effects, the present invention provides a mixed material sampling and testing tool, which includes a sampling tube, a straight tube, and four filter slots on the straight tube. The four filter slots are linearly and evenly distributed along the length of the straight tube, and each filter slot is set along the cross-sectional direction of the straight tube. Each filter slot is fitted with a filter screen, which is divided into a first filter screen, a second filter screen, a third filter screen, and a fourth filter screen. The front end of the straight tube is the sampling end, and the rear end of the straight tube is the sampling end. Along the direction from the sampling end to the sampling end of the straight tube, the mesh size of the first filter screen, the second filter screen, the third filter screen, and the fourth filter screen increases sequentially.

[0006] Furthermore, each filter screen groove includes an annular groove and a through groove. The annular groove is located on the inner wall of the straight pipe and is coaxial with the straight pipe. The inner diameter of the annular groove is larger than the inner diameter of the straight pipe. The through groove is located at the upper part of the annular groove and penetrates the side wall of the straight pipe at the upper part of the annular groove. The width of the through groove is the same as the inner diameter of the annular groove, and the thickness of the through groove is the same as the thickness of the annular groove.

[0007] Furthermore, the first filter screen includes a filter screen I and a cylindrical head I. The filter screen I is circular in shape, and the cylindrical head I is fixedly connected to the outer wall of the filter screen I. The filter screen I is inserted into the filter screen groove, and the cylindrical head I extends out of the filter screen groove. The second filter screen includes a filter screen II and a cylindrical head II. The filter screen II is circular in shape, and the cylindrical head II is fixedly connected to the outer wall of the filter screen II. The filter screen II is inserted into the filter screen groove, and the cylindrical head II extends out of the filter screen groove. The third filter screen package... The first filter includes a filter screen III and a cylindrical head III. The filter screen III is circular in shape, and the cylindrical head III is fixedly connected to the outer wall of the filter screen III. The filter screen III is inserted into the filter screen groove, and the cylindrical head III extends out of the filter screen groove. The fourth filter includes a filter screen IV and a cylindrical head IV. The filter screen IV is circular in shape, and the cylindrical head IV is fixedly connected to the outer wall of the filter screen IV. The filter screen IV is inserted into the filter screen groove, and the cylindrical head IV extends out of the filter screen groove. The mesh size of the filter screens I, II, III, and IV increases sequentially.

[0008] Furthermore, the outer diameters of filter screen I, filter screen II, filter screen III, and filter screen IV are all the same, and the outer diameter of filter screen I is the same as the inner diameter of the annular groove; the thicknesses of filter screen I, filter screen II, filter screen III, and filter screen IV are all the same, and the thickness of filter screen I is the same as the thickness of the annular groove.

[0009] Furthermore, a plug is connected to the rear end of the straight pipe. The plug includes a blind plate, a rubber plug, and a handle. The rubber plug is fixedly connected to the top surface of the blind plate and inserted into the inside of the straight pipe. The handle is fixedly connected to the bottom surface of the blind plate and is U-shaped.

[0010] Furthermore, a connecting pipe is fixed on the top surface of the blind plate, the inner wall of the connecting pipe is provided with internal threads, and the outer wall of the rear end of the straight pipe is provided with external threads, with the internal threads connected to the external threads.

[0011] Furthermore, the sampling tube includes a tapered tube, the rear end of which is fixedly connected to the front end of the straight tube, and the inner diameter of the front end of the tapered tube is larger than the inner diameter of the rear end of the tapered tube.

[0012] Furthermore, the front end of the tapered tube is an inclined surface, and the distance between the bottom surface of the inclined surface at the front end of the tapered tube and the rear end of the tapered tube is greater than the distance between the top surface of the inclined surface at the front end of the tapered tube and the rear end of the tapered tube.

[0014] Furthermore, the blind flange, connecting pipe, and handle are all made of carbon steel.

[0015] The beneficial effects of this utility model are as follows: This utility model uses a first, second, third, and fourth filter screen to block the material inside the straight pipe. Since the mesh size of filter screens I, II, III, and IV increases sequentially, the largest particles are blocked by filter screen I, particles smaller than the pore size of filter screen I are blocked by filter screen II, particles smaller than the pore size of filter screen II are blocked by filter screen III, and particles smaller than the pore size of filter screen III are blocked by the fourth filter screen. The smallest particles pass through filter screen IV. This utility model allows for sampling at different locations of the bagged material. Then, the material poured out from the sampling end at the rear of the straight tube is the smallest particle size. Next, filter screens IV, III, II, and I are removed sequentially, thus achieving the pouring out of material particles from smallest to largest. This allows for the differentiation of different particle sizes, facilitating observation of the composition of different particle sizes without the need for secondary sorting using sieves or other tools. This improves the accuracy of sampling inspection of bagged materials, effectively reduces manual labor intensity, and increases the efficiency of bagged material sampling inspection. This utility model has a simple structure, is easy to manufacture, convenient to use, and has promotional value. Attached Figure Description
