Description

Technical Field

[0001] The invention relates to the technical field of microwave digestion, in particular to a digestion device for detecting water quality in a fish pond. Background Art

[0002] A digester is an instrument used for water sample analysis. It is mainly used to heat and digest pollutants such as organic and inorganic substances in water samples. It can effectively decompose pollutants in water samples into simple substances or low-molecular compounds, reduce errors in subsequent detections, and improve detection sensitivity and accuracy. The water quality in fish ponds is particularly important for the growth of fish. After staff take samples of the water in the fish pond, they usually use a digester for heating and digestion to test the water quality in the fish pond.

[0003] When testing the water quality of a fish pond, samples are usually taken from the upper, middle and lower layers of the water in the fish pond, and then the sampled water is extracted with a syringe and transferred to a digestion tank. This may make the sampling of the water and the transfer to the digestion tank more cumbersome and inconvenient. After placing the digestion tank containing the water sample on the placement rack, the staff also needs to lift the entire placement rack and place it in the digestion instrument. After the digestion is completed, the entire placement rack needs to be taken out of the digestion instrument, and then the digestion tank is taken out of the placement rack. This may be inconvenient for the staff to use, and when the placement rack is lifted and placed in the digestion instrument or taken out of the digestion instrument, it may cause the placement rack to bump or fall, resulting in damage to the placement rack or the digestion tank. For this reason, we propose a digestion device for fish pond water quality testing. Summary of the invention

After the sampling rod 22 is completely inserted into the insertion hole 23, the block 25 is inserted into the card slot 24 under the elastic force of the first spring 26, so that the sampling rod 22 is installed on the sampling tube 21. Subsequently, the sampling tube 21 is inserted into the fish pond through the sampling rod 22 to perform sampling. After the sampling is completed, the pressing plate 27 can be held by hand to move the pressing plate 27 to the groove at the side end of the sampling rod 22, and the block 25 is driven to move out of the card slot 24 to remove the sampling rod 22 from the sampling tube 21, so as to facilitate the subsequent distribution of the water sample in the sampling tube 21 into the digestion tank 13 in sequence.

[0042] Three water storage chambers 29 are arranged on the inner side of the sampling tube 21 from top to bottom. The sampling tube 21 is symmetrically provided with water inlet grooves 212 on the upper sides of the three water storage chambers 29. The water inlet grooves 212 are arranged upwardly and inclined from the water storage chambers 29 to both sides. A filter is arranged on the outer end of the water inlet groove 212 to prevent impurities in the water in the fish pond from entering the water inlet groove 212. Brackets 215 and connecting frames 213 are slidably arranged on the upper and lower sides of the sampling tube 21, respectively. The sampling tube 21 is provided with penetrating notches at the brackets 215 and the connecting frames 213, which can guide and limit the up and down movement of the brackets 215 and the connecting frames 213. Floats 216 are fixed on both sides of the brackets 215, and a gravity ball 216 is fixed on the lower end of the connecting frame 213. 14. A second spring 217 fixed to the sampling tube 21 is symmetrically fixed on the upper side of the bracket 215. Two first blocking blocks 210 are fixed from top to bottom on both sides of the vertical sections of the bracket 215. The upper first blocking block 210 is used to block the upper water inlet trough 212. Two second blocking blocks 211 are fixed from top to bottom on both sides of the vertical sections of the connecting frame 213. The lower second blocking block 211 is used to block the lower water inlet trough 212. The lower first blocking block 210 and the upper second blocking block 211 are used to block the middle water inlet trough 212. Guide plates fixed to the sampling tube 21 are provided on both sides of the first blocking block 210 and the second blocking block 211 to guide the up and down movement of the first blocking block 210 and the second blocking block 211.

[0043] When the sampling tube 21 is inserted into the fish pond for sampling through the sampling rod 22, the connection frame 213 moves upward relative to the sampling tube 21 under the resistance of the gravity ball 214 at the bottom of the fish pond, so that the second blocking blocks 211 on both sides move upward. The upward movement of the lower second blocking block 211 will release the blocking effect on the lower water inlet trough 212, so that the water in the lower layer of the fish pond can enter the lower water storage chamber 29 through the lower water inlet trough 212. The upward movement of the upper second blocking block 211 will block the middle water inlet trough 212 to prevent the water in the lower layer of the fish pond from entering. After the sampling tube 21 is inserted into the fish pond, the float 216 is acted upon by the buoyancy, which causes the bracket 215 to move upward, and the second spring 217 is compressed, causing the first blocking blocks 210 on both sides to move upward. The upward movement of the lower first blocking block 210 can ensure that the sampling tube 211 continues to be pressed into the depth of the fish pond, and will not hinder the upward movement of the upper second blocking block 211 when sampling the lower water body. The upward movement of the upper first blocking block 210 will block the upper water inlet trough 212, preventing the water bodies in the lower and middle layers of the fish pond from entering the upper water storage chamber 29.

[0044] After sampling the lower layer of the fish pond, the sampling tube 21 is moved upward in the fish pond through the sampling rod 22. Under the gravity of the gravity ball 214, the connecting frame 213 and the second blocking blocks 211 on both sides move downward relative to the sampling tube 21. The downward movement of the lower second blocking block 211 will block the lower water inlet trough 212 to prevent the water in the middle and upper layers from mixing into the lower water storage chamber 29. The downward movement of the upper second blocking block 211 will release the blocking effect on the middle water inlet trough 212, thereby allowing the water in the middle layer of the fish pond to enter the middle water storage chamber 29. The tube 21 continues to move upward. When the float 216 moves out of the water, the bracket 215 moves downward relative to the sampling tube 21 under the elastic force of the second spring 217, causing the first blocking blocks 210 on both sides to move downward. The downward movement of the lower first blocking block 210 will block the middle water inlet trough 212 to prevent the upper water from entering the middle water storage chamber 29. The downward movement of the upper first blocking block 210 will release the blocking effect on the upper water inlet trough 212, allowing the upper water in the fish pond to enter the upper water storage chamber 29, thereby facilitating sampling of the upper, middle and lower water in the fish pond.

[0045] One side of the three water storage chambers 29 is connected to a water outlet pipe 218 fixed to the sampling tube 21.
