Description

Technical Field

[0001] The utility model relates to the technical field of samplers, in particular to a sampler for pasty experimental materials. Background Art

[0002] The sampler is a sampling device used for sampling and cooling of steam and water in boiler rooms or power plants. It is used for heat exchange with liquids and gases at relatively high temperatures. The water in boilers and thermal systems is mostly at a relatively high temperature, and high water temperature is not convenient for sampling and testing. Therefore, it should be cooled during sampling, that is, the sample at the sampling point should be introduced into the sampling cooler for cooling.

[0003] When sampling paste-like experimental materials, the traditional method is to directly sample the surface of the paste-like experimental materials. If the experimental materials are exposed to the air for a long time, the surface of the experimental materials will be contaminated, and direct sampling will affect the accuracy of the experiment.

When the sampler barrel 1 contacts an object containing the pasty experimental material, the space between the two is increased. Friction force, the interior of the two sleeves 2 are rotatably connected with the sampling cylinder 3, the inner walls of the two sampling cylinders 3 are fixedly connected with the spiral blade 4, the upper end of the sampler cylinder 1 is installed with a driving gear 5, the upper surface of the driving gear 5 is fixedly connected with the main handle 21, the driving gear 5 can rotate, the outer surfaces of the two sampling cylinders 3 are fixedly connected with the driven gear 6, the two driven gears 6 are symmetrically arranged, and the two driven gears 6 are meshed with the driving gear 5. The interior of the sampler cylinder 1 is plugged with a collecting cylinder 7, and the collecting cylinder 7 can be disassembled. The bottom end of the collecting cylinder 7 is sealed, and the outer surface of the collecting cylinder 7 is provided with two symmetrical inlets and outlets 8. The outer surface of the collecting cylinder 7 is in close contact with the inner wall of the sampler cylinder 1, and the collecting cylinder 7 is in close contact with the inner wall of the sampler cylinder 1. The upper surface is fixedly connected with a rotating drum 9, which is plugged into the main handle 21, and the rotating drum 9 can rotate along the inner wall of the main handle 21. The inner wall of the rotating drum 9 is rotatably connected with a rotating column 12. The bottom surface of the rotating column 12 is fixedly connected with two symmetrical scrapers 22. The two scrapers 22 are in close contact with the inner wall of the collecting cylinder 7. When the rotating column 12 is rotated, the two scrapers 22 can be driven to rotate. The two scrapers 22 can not only scrape off the paste test material remaining on the inner wall of the collecting cylinder 7, but also seal the two inlets and outlets 8. A through hole A13 and two through holes B14 are provided inside the rotating column 12. The two through holes B14 are connected to the through hole A13. The inside of the through hole A13 is filled with liquid, and the insides of the two through holes B14 are slippery. It is dynamically connected to the piston A15, and the inner wall of the through hole A13 is slidingly connected to the piston B20. The upper surface of the piston B20 is fixedly connected to the push rod 16. When the push rod 16 is pushed downward, the hydraulic pressure inside the through hole A13 and the two through holes B14 can be increased, so that the piston B20 can be in contact with the rotating cylinder 9, and there is friction between the two, which can improve the stability between the rotating column 12 and the rotating cylinder 9. The inner wall of the through hole A13 is fixedly connected to the limit ring 17, and the push rod 16 is slidingly connected to the limit ring 17. The limit ring 17 can limit the piston A15 to prevent the piston A15 from falling off. The upper end of the rotating column 12 is fixedly connected to the handle A18, and the upper end of the rotating cylinder 9 is fixedly connected to the handle B19.

[0027] When in use, first insert the bottom of the sampler barrel 1 into the paste test material so that the bottom surface of the sampler barrel 1 contacts the object containing the paste test material. The multiple anti-slip grooves 11 can increase the friction between the two and improve the stability between the two. At this time, the two sampling barrels 3 are placed inside the paste test material, and then the handle A18 is rotated. The handle A18 drives the rotating column 12 to rotate, and the rotating column 12 drives the two scrapers 22 to rotate. The scrapers 22 are rotated ninety degrees to achieve the purpose of opening the two inlets and outlets 8. Then the push rod 16 is pressed, and the push rod 16 drives the piston A15 to descend. When the piston A15 descends, the hydraulic pressure inside the through hole A13 and the two through holes B14 increases, and the liquid inside the two through holes B14 pushes the two pistons B20 to move toward the rotating cylinder 9 and squeeze the rotating cylinder 9. The two pistons B20 There is direct friction with the rotating cylinder 9. The friction between the two pistons B20 and the rotating cylinder 9 is utilized to hold the rotating cylinder 9 and keep the rotating cylinder 9 and the rotating column 12 stationary. At this time, the main handle 21 is rotated, and the main handle 21 drives the driving gear 5 to rotate, and the driving gear 5 drives the two driven gears 6 to rotate. The two driven gears 6 respectively drive the two sampling cylinders 3 to rotate, and the two sampling cylinders 3 respectively drive the two spiral blades 4 to rotate. The two spiral blades 4 transport the paste test material through the two inlets and outlets 8 to the collecting cylinder 7. Since the number of revolutions of the two spiral blades 4 can be freely controlled, quantitative material can be taken. Since the two sleeves 2 are arranged horizontally when taking the material, the inside of the paste material can be sampled directly to avoid contact with other parts of the paste material, thereby improving the accuracy of the experiment and solving the problems raised in the background technology.

[0028] Finally, turn the handle A18 again to reset the two scrapers 22. The two scrapers 22 can block the two inlets and outlets 8 to prevent material leakage. They can also prevent external foreign matter and dust from entering the collecting barrel 7 through the inlets and outlets 8, preventing external foreign matter and dust from affecting the accuracy of the test. Then pull the handle B19 upward to pull out the collecting barrel 7. When the material needs to be removed, turn the handle B19 to rotate the scraper 22 to discharge the test material from the inlet and outlet 8. The scraper 22 can also scrape off the residual material in the collecting barrel 7.
