Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to a sample processing device and method for environmental monitoring. Background Art

[0002] As environmental pollution becomes increasingly serious, the importance of environmental monitoring becomes increasingly prominent. The core of environmental monitoring is to obtain accurate and reliable sample data, and sample processing is the key to ensuring data quality. Traditional environmental monitoring sample processing methods mainly rely on manual operations, which have problems such as low efficiency, large errors, and high costs, and are difficult to meet the growing demand for environmental monitoring.

[0003] However, there are usually some problems in the daily use of ordinary sample processing equipment for environmental monitoring. With the development of science and technology, technicians in related fields have also made a lot of optimizations on sample processing equipment for environmental monitoring. In order to make a more accurate comparison, a Chinese patent with announcement number CN222419716U discloses a soil sample processing device for environmental governance, including a processing box, a heating base, a support table and a vibration component. The processing box is fixed on the top of the heating base, and the vibration component is installed on the top of the support table, and the vibration component moves through the outer wall of the processing box; the processing box includes a box body, a pressing plate, a sieve plate and two springs, and the pressing plate and the sieve plate are both slidably arranged in the inner cavity of the box body. The opposite sides of the pressing plate and the sieve plate are connected to the top inner wall and the bottom inner wall of the box body by a spring. The above-mentioned prior art can make the collected block soil samples crushed in the processing box and dried at the same time, thereby shortening the soil sample processing time, improving the processing efficiency of the user, and also facilitating the user to clean up the soil sample after processing, and reducing the residue of the soil sample in the processing box.

[0004] However, the above-mentioned soil sample processing device for environmental governance still has some shortcomings in actual use: 1. The soil sample processing device for environmental management mentioned above: through the coordinated use of the processing box, the heating base and the vibration component, the collected bulk soil samples can be broken in the processing box, but a large number of samples will accumulate in the same place during the breaking, resulting in incomplete breaking of the samples, which in turn causes the samples to fail to meet the monitoring requirements.

[0005] 2. The soil sample processing device for environmental management mentioned above: through the coordinated use of the processing box, the heating base and the vibration component, the drying process can be carried out while the soil is crushed, thereby shortening the soil sample processing time and improving the processing efficiency of the user. However, drying during crushing will reduce the area of ​​the sample in contact with the outside world, resulting in incomplete drying.

[0006] Therefore, under the viewpoints stated above, there is still room for improvement in the sample processing equipment and methods for environmental protection monitoring in the prior art. Summary of the Invention

The heating fan 50 can blow hot air into the drying outer shell 1, and the hot air blown into the drying outer shell 1 will pass through the ventilation pipes 5, thereby accelerating the drying speed of the sample in the drying frame 35.

[0050] In addition, the present invention also provides a sample processing method for environmental monitoring, including the following steps: The first step: The operator puts the sample into the crushing outer shell 13 from the feeding port 14. When the operator puts the sample into the crushing outer shell 13, the sample抵触 the arc-shaped triangular block 21, and the sample moves along the top of the arc-shaped triangular block 21, thereby roughly dispersing the sample to the top of the filter screen 23; at the same time, the operator puts a suitable counterweight into the drying frame 35 to drive the drying frame 35 to rotate.

[0051] The second step: Then start the driving motor 11. When the driving motor 11 rotates, it can drive the central shaft 12 to rotate together. When the central shaft 12 rotates, it can drive the U-shaped rod 22 to rotate together. When the U-shaped rod 22 rotates, it can scrape off the sample adhered to the inner wall of the crushing outer shell 13 to prevent sample residue; at the same time, when the U-shaped rod 22 rotates, it can drive the rotating shaft 24 to rotate. When the rotating shaft 24 rotates, it can drive the first gear 281 to rotate together. Through the cooperation of the first gear 281 and the gear ring 280, the first gear 281 can rotate while rotating. When the first gear 281 rotates, it can drive the rotating shaft 24 far from the central shaft 12 to rotate together; at the same time, when the first gear 281 rotates, it can drive the second gear 283 to rotate together. When the second gear 283 rotates, it can drive the transmission shaft 282 to rotate together. When the transmission shaft 282 rotates, it can drive the rotating shaft 24 close to the central shaft 12 to rotate together. When the rotating shaft 24 rotates, it can drive the adjacent rotating shaft 26 to rotate together, thereby realizing the driving of the rotating shaft 24 and the rotating shaft 26 to rotate.

[0052] The third step: When the rotating shaft 24 and the rotating shaft 26 rotate, when the rotating shaft 24 rotates, it can drive the arc-shaped push plate 25 to rotate together. When the arc-shaped push plate 25 rotates, it can drive the sample to move together, thereby further driving the sample to disperse. When the rotating shaft 26 rotates, it can drive the grinding knife 27 to rotate together. When the grinding knife 27 rotates, it can break the large sample into small samples that meet the requirements. Finally, the samples that meet the requirements can enter the drying outer shell 1 through the filter screen 23.

[0053] Step 4: When the U-shaped rod 22 rotates, it can drive the T-shaped block 47 to rotate along the top of the wavy ring 46, thereby driving the wavy ring 46 to move up and down. When the wavy ring 46 moves up and down, it can drive the filter net 23 to move up and down. When the filter net 23 moves, it can drive the vibration plate 40 to move together. The spring two 42 can assist the vibration of the filter net 23; when the filter net 23 moves up and down, it pushes the L-shaped baffle 43 to slide in the chute 44, and the L-shaped baffle 43 prevents the sample on the top of the filter plate from falling outside the crushing housing 13; during this process, when the U-shaped rod 22 rotates, it can drive a plurality of telescopic rods 48 to rotate together. When the telescopic rods 48 rotate, it can further accelerate the speed of the sample passing through the filter net 23.

[0054] Step 5: The qualified samples can enter the dispersion cylinder 31 through the centralized hopper 30. Then, when the central shaft 12 rotates, it can drive the arc-shaped block 32 to rotate together. When the arc-shaped block 32 rotates, it will push the samples in the dispersion cylinder 31 into the transmission pipe 33. The samples in the transmission pipe 33 can be transmitted into the retaining frame 34, and the samples in the retaining frame 34 can fall into the drying frame 35; when the samples in the dispersion cylinder 31 continuously enter the drying frame 35 along the transmission pipe 33, the weight of the samples drives the drying frame 35 to rotate against the weight of the counterweight block. During this process, when the drying frame 35 rotates, it can drive the traction cable 368 to move under the restriction of the support rod 367. When the traction cable 368 moves, it can drive the T-shaped rod 366 to move. When the T-shaped rod 366 moves, it can drive the pressing plate 364 to move together. When the pressing plate 364 moves, it can push the circular baffle 362 to move together. When the sample is the same as the counterweight block, the circular baffle 362 completely enters the transmission pipe 33, thereby cutting off the transmission of the sample by the transmission pipe 33, realizing the division of the sample into quantitative small portions and drying, and then dividing the sample into small portions according to the requirements of the operator for the operator to monitor.

[0055] Step 6: The hot air fan 50 can blow hot air into the drying housing 1, and the hot air blown into the drying housing 1 will pass through the ventilation pipe 5, thereby accelerating the drying speed of the samples in the drying frame 35.
