Description

Technical Field

[0001] The invention relates to the technical field of powder detection sample recovery devices, and in particular to an automatic sample recovery system. Background Art

[0002] With the development of science and technology in my country, the demand for various solid sample testing laboratories is increasing, and key laboratories in various disciplines, schools, and systems are emerging in an endless stream. From the distribution of laboratories, they are mainly concentrated in the inspection departments, schools, scientific research institutes, and testing institutions in enterprises. At present, due to environmental protection and occupational health requirements, dust pollution in various production workshops has received attention, but various laboratories are mostly relatively independent and regionally dispersed, so dust pollution is easy to be ignored.

[0003] At present, most of the sample recovery is done by manually dumping samples from sample barrels, causing powder to splash and come into contact with the human body. If the solid laboratory does not pay attention to the pollution protection of dust samples, it is actually a typical small dust pollution source. The more it is built, the greater the pollution. Since dust cannot be observed with the naked eye, the testers in these laboratories often ignore the harm of dust to the body. Micron-level dust has the characteristics of light weight, small particle size, and high buoyancy. It is easily disturbed by the ambient airflow and spreads to the entire laboratory, causing the dust concentration in the test environment to increase, which is prone to combustion and explosion accidents; it can also cause pulmonary fibrosis in testers and increase the risk of pneumoconiosis.

[0043] Workflow: When the system is started, the ventilation and dust removal mechanism 5 starts to work and collects dust on the sample bag 309. At the same time, the packaging bag collection mechanism 6 is also in a standby state. When the sample bag 309 is transported to the designated location, the packaging bag collection mechanism 6 starts to work, clamps the sample bag 309, lifts it to a certain height, and then puts it into the packaging bag collection box 601. In this way, the automatic collection and sorting of the sample bag 309 is completed.

A plurality of vertical annular filter nets 909 with gradually decreasing mesh sizes are sequentially provided on the second filter bucket 908 along a direction away from the vertical axis 904.

[0048] A vertical pipe 11 is fixedly provided at the left end of the annular filter screen 909, and the vertical pipe 11 passes through the second filter bucket 908 from top to bottom. A solenoid valve 12 is fixedly installed at the bottom of each vertical pipe 11. The center of the box body 902 is fixedly connected to a horizontal partition 13, and a circle of annular grooves 1301 are provided on the partition 13 corresponding to the bottom of each vertical pipe 11. The bottom of the annular groove 1301 is fixedly connected to a discharge pipe 1302 along the radial direction. The bottom of the box body 902 is radially slidably connected to a plurality of drawers 14, and a plurality of sample storage boxes 1401 are fixedly installed inside the drawers 14 corresponding to each vertical pipe 11; a vibration mechanism 10 is fixedly provided at the bottom of the box body 902, and the vibration mechanism 10 is used to provide vibration force to the box body 902; The vibration mechanism 10 includes: a vertical rod 1001 2, the box body 902 is symmetrically fixedly connected to the vertical rod 1001 2, the vertical rod 1001 slides up and down and passes through the box base 1304, the outside of the vertical rod 1001 is located on the top of the box base 1304 and a spring 1002 is sleeved, the middle of the bottom end of the box body 902 is fixedly connected to the vertical plate 1003, the right end of the vertical plate 1003 is rotatably connected to the bevel gear 3 1004, the bevel gear 3 1004 is meshed and connected to the bevel gear 4 1005, the top of the bevel gear 4 1005 is fixedly connected to the bottom end of the vertical shaft 1 904, the left end of the axis of the bevel gear 3 1004 is fixedly connected to the cam 1303, and the cam 1303 is pressed tightly against the top of the box base 1304.

[0049] The working principle of the above technical solution has the following beneficial effects: on the basis of Example 2, the technical solution adds a sample screening, classification and storage mechanism 9 and a vibration machine mechanism to achieve the screening, classification and storage of samples. Its working principle is as follows: Sample screening, classification and storage organization 9: When the cut powder samples of different particle sizes fall into the spiral conveying tube 901 from the sample recovery box 421, the spiral conveying tube 901 conveys the samples upward to the feed port of the box body 3 902 through the spiral blades inside the spiral conveying tube 901.

[0050] After entering the box body 3 902, the sample first falls on the conical filter 906. The conical filter 906 is provided with a plurality of filter screens 907 with gradually decreasing mesh sizes in a direction away from the vertical axis 1 904. In this way, sample particles of different sizes will pass through filter holes of different sizes and fall into the second filter 908 below.

[0051] The second filter 908 is high in the middle and low in the periphery, and a plurality of vertical annular filter screens 909 with gradually decreasing mesh sizes are arranged on it in sequence along the direction away from the vertical axis 1 904. The mesh size of the first circle of filter screen 2 closest to the center of the vertical axis 1 904 is equal to the mesh size of the second circle of filter screen 1 907, and the mesh size of the second circle of filter screen 2 is equal to the mesh size of the third circle of filter screen 1 907, and so on from the center of the vertical axis 1 904 outwards, which further screens the sample so that finer particles can pass through smaller filter holes.

[0052] The screened sample particles fall into the corresponding vertical tube 11, and a solenoid valve 12 is installed at the bottom of each vertical tube 11. When a certain type of sample needs to be discharged, the corresponding solenoid valve 12 is opened, and the sample particles fall into the sample storage box 1401 in the corresponding drawer 14 through the annular groove 1301 and the discharge pipe 1302. When the solenoid valve 12 is opened, the vertical tube 11 in the annular groove 1301 will automatically discharge the sample particles only when it passes through the discharge pipe 1302.

[0053] The drawer 14 can slide radially to facilitate taking out and replacing the sample storage box 1401.

[0054] Vibration machine mechanism: The box body 3 902 is fixedly connected to the vertical rod 2 1001 symmetrically on the left and right. The vertical rod 2 1001 slides up and down to penetrate the box body base 1304, and a spring 2 1002 is sleeved on the outside.

[0055] When the box body 3 902 needs to be vibrated to facilitate the sample particles to pass through the filter screen better, the external mechanism vertical shaft 1 904 can be used to rotate and drive the bevel gear 4 1005 to rotate. The bevel gear 4 1005 meshes and drives the bevel gear 3 1004 and the cam 1303 to rotate synchronously. The cam 1303 rotates back and forth to lift the box body 3 902 up and down, causing the box body 3 902 to vibrate. This vibration is transmitted to the inside of the box body 3 902 through the vertical rod 2 1001 and the spring 2 1002, causing the sample particles to be disturbed on the conical filter 906 and the second filter 908, making it easier to pass through the filter screen.

[0056] Beneficial effects: Automatic screening and classification: The different sizes of filter screens on the conical filter 906 and the second filter 908 enable automatic screening and classification of dust particles of different sizes, which greatly improves the efficiency and accuracy of sample processing.

[0057] Flexible storage: The 14-drawer design allows the sample storage box 1401 to be easily removed and replaced, making it easier to store and manage different types of samples separately.

[0058] Vibration promotes screening: The design of the vibration machine mechanism allows the box 902 to generate vibrations, which helps sample particles pass through the filter better, reducing clogging and incomplete screening problems.

[0059] Compact structure: The entire sample screening classification storage mechanism 9 and the vibration machine mechanism are designed to be relatively compact, occupying a small space, and are suitable for use in a limited space. The same motor drive source can achieve the effects of applying both rotational centrifugal force and vibration force to the sample.
