Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of digestion and filtration devices, specifically to an integrated digestion and filtration device. Background Technology
[0002] In the detection of heavy metal ions, such as lead, cadmium, mercury, copper, and zinc, in environmental water samples, such as surface water, industrial wastewater, and groundwater, sample pretreatment is a crucial step in ensuring the accuracy of test results. Samples typically require digestion and filtration, primarily to break down organic matter, release heavy metal ions, and remove impurities to improve detection efficiency and accuracy. However, traditional ultraviolet digestion processes often employ a single ultraviolet light source and a straight-tube reaction chamber, which has a limited ultraviolet irradiation area. This results in incomplete decomposition of organic matter and low release rates of heavy metal ions, especially when dealing with complex matrices (such as colloidal heavy metal complexes and high-concentration organic matter), significantly reducing digestion efficiency and thus affecting detection efficiency and causing data deviations. Utility Model Content

[0005] An integrated digestion and filtration device includes: a digestion mechanism comprising an upper chamber and a lower chamber, wherein a plurality of ultraviolet digestion lamps are fixedly connected between the upper and lower chambers, and each ultraviolet digestion lamp is surrounded by a spiral coil, the two ends of which are respectively connected to the upper and lower chambers; a mixing component is also installed inside the upper chamber; the upper chamber has a first inlet and a second inlet, and a feed pump is connected through the first inlet and a reagent addition pump is connected through the second inlet; the upper chamber contains a mixing component for mixing materials and reagents; and a filtration mechanism is connected to the lower chamber through a delivery pump.
[0006] A further technical solution is that the spiral coil is made of quartz material, and its inner diameter is set to 2mm~3mm.
[0007] A further technical solution is that a number of light-shielding plates are fixedly connected between the upper cavity and the lower cavity.

[0009] A further technical solution is that the mixing shell is connected to the first feed port and the second feed port respectively through two connecting pipes.
[0010] The working principle and beneficial effects of this application are as follows:

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0020] like Figures 1-4 As shown, an integrated digestion and filtration device includes a digestion mechanism 1, which comprises an upper cavity 11 and a lower cavity 13. A plurality of ultraviolet digestion lamps 14 are fixedly connected between the upper cavity 11 and the lower cavity 13. Each ultraviolet digestion lamp 14 is surrounded by a spiral coil 15. The two ends of the spiral coil 15 are respectively connected to the upper cavity 11 and the lower cavity 13. A mixing component is also installed inside the upper cavity 11. The upper cavity 11 has a first feed port 16 and a second feed port 17. A feed pump 2 is connected through the first feed port 16, and a reagent addition pump 3 is connected through the second feed port 17. The upper cavity 11 has a mixing component for mixing materials and reagents. The lower cavity 13 is connected to a filtration mechanism 5 through a delivery pump 4.
[0021] In this embodiment, the water sample to be digested is transported to the upper cavity 11 by the feed pump 2. At the same time, the reagent addition pump 3 injects the reagent required for digestion into the upper cavity 11. The water sample and reagent are thoroughly stirred by the mixing component to form a uniform mixture. The mixture flows from the upper cavity 11 into multiple spiral coils 15 and is left to stand. The ultraviolet digestion lamp 14 emits ultraviolet light, which is irradiated and digested through the spiral coils 15. After digestion is completed, the valve at the bottom of the lower cavity 13 is opened, and the digestion liquid in the lower cavity 13 is extracted by the transfer pump 4 and pumped into the filtration mechanism 5. The filtration mechanism 5 performs solid-liquid separation on the digestion liquid to remove undissolved impurities or particulate matter, and finally obtains a clear filtrate for subsequent detection or processing.
[0022] The spiral coil 15 is arranged around the ultraviolet digestion lamp 14 to form a spiral channel, thereby increasing the ultraviolet light irradiation area and improving the digestion efficiency. The spiral coil 15 is made of quartz material and has an inner diameter of 2~3mm.
[0023] like Figure 2As shown, a plurality of light-shielding plates 12 are fixedly connected between the upper cavity 11 and the lower cavity 13. These light-shielding plates 12 are evenly arranged around a plurality of ultraviolet (UV) digestion lamps 14, surrounding them. The inner surface of each light-shielding plate 12 facing the UV digestion lamp 14 is designed as a mirror, and the distance between the inner surface of the light-shielding plate 12 and the UV digestion lamp 14 is 5mm to 10mm. The light-shielding plates 12 enclose the UV digestion lamps 14 to prevent UV light leakage, protecting operators. The mirrored design on the inner side of the light-shielding plate 12 reflects UV light, improving light utilization and enhancing digestion efficiency.
[0024] like Figures 3-4 As shown, the mixing assembly includes a mixing motor 110 and a mixing housing 19. The mixing housing 19 is connected to both the first feed inlet 16 and the second feed inlet 17. A stirring rod 111 is fixed to the output end of the mixing motor 110. The stirring rod 111 extends into the mixing housing 19 and is fixed with several stirring blades 112. Multiple evenly distributed liquid outlet holes 113 are opened on the side wall of the mixing housing 19. The mixing housing 19 is connected to the first feed inlet 16 and the second feed inlet 17 through two connecting pipes 18, respectively.
[0025] In this embodiment, the water sample to be treated and the digestion reagent are combined and discharged into the mixing component. The mixing motor 110 drives the stirring rod 111 to rotate, which in turn drives the multiple stirring blades 112 on its outer wall to rotate synchronously, so as to quickly mix the water sample and the reagent and ensure that the digestion reaction is carried out uniformly. The liquid outlet hole 113 is provided for the mixture to overflow and enter the multiple spiral coils 15 evenly for settling, thereby carrying out the digestion operation.
[0026] During use, the feed pump 2 delivers the water sample to be digested to the upper chamber 11 through the first feed port 16, while the reagent addition pump 3 injects the digestion reagent through the second feed port 17. The water sample and reagent enter the mixing assembly through the connecting pipe 18. The mixing motor 110 drives the stirring rod 111 and stirring blade 112 to rotate at high speed, which fully stirs the mixture in the mixing shell 19 to form a uniform mixture. The mixture overflows through the liquid outlet 113 on the outer wall of the mixing shell and enters the spiral coil 15 between the upper chamber 11 and the lower chamber 13. The mixture is left to stand in the spiral coil 15. The ultraviolet digestion lamp 14 emits ultraviolet light, which irradiates the water sample through the spiral coil 15 for digestion. After digestion is completed, the valve at the bottom of the lower chamber 13 is opened, and the digestion liquid in the lower chamber 13 is extracted by the transfer pump 4 and pumped into the filtration mechanism 5. The filtration mechanism 5 performs solid-liquid separation on the digestion liquid to remove undissolved impurities or particulate matter, and finally obtains a clear filtrate for subsequent detection or processing.
[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
