Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and in particular to a digestion and colorimetric device for use in water quality monitoring instruments. Background Technology

[0002] Digestion apparatus is a commonly used sample pretreatment device. According to the degree of automation, it can be divided into semi-automatic digestion apparatus and fully automatic digestion apparatus; according to the principle, it can be divided into electrothermal digestion apparatus and microwave digestion apparatus. Both have relatively mature products and are widely used.

[0003] Water quality monitoring digestion colorimetric devices are generally digestion instruments. Traditional digestion instruments require the reagents and solutions to be poured into the digestion tubes, the caps to be closed, and then the digestion tubes to be placed in the placement holes on the surface of the digestion instrument for heating. During the heating process, the caps must be used to cover the entire digestion tube and digestion area. After heating, the digestion tubes must be removed from the top and placed on a rack. In this process, because the digestion tubes have been heated to a high temperature, it is inconvenient to remove them directly. In addition, each test tube is placed in an independent placement hole, resulting in uneven heating. Moreover, heat dissipation is achieved by letting the tubes cool naturally after they are removed, which is inefficient. Utility Model Content

This invention solves the problems of the following: in the process of using a digestion instrument, reagents and solutions need to be poured into a digestion tube, the lid needs to be closed, and then the digestion tube needs to be placed in the placement hole on the surface of the digestion instrument for heating. During the heating process, the lid also needs to be used to cover the entire digestion tube and digestion area. After heating, the digestion tube needs to be removed from the top and placed on a rack. In this process, because the digestion tube has been heated at high temperature, it is inconvenient to directly remove and place it. In addition, each test tube is placed in an independent placement hole, resulting in uneven heating. Moreover, heat dissipation is achieved by natural cooling after removal, which results in low heat dissipation efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0026] Reference Figure 1-5A digestion and colorimetric device for use in a water quality monitor includes a digester body 1. The surface of the digester body 1 has a placement hole for holding a digestion tube. A heating sleeve 2 is installed inside the placement hole. A vertical rod 5 is fixedly installed on the top of the digester body 1. A sliding rod 6 is slidably connected to the surface of the vertical rod 5. A first electric telescopic rod 7 is fixedly installed inside the vertical rod 5. The output end of the first electric telescopic rod 7 is fixedly connected to the sliding rod 6. A connecting ring 12 is fixedly installed at the bottom of the sliding rod 6. A heat-conducting cylinder 9, matching the size of the placement hole, is rotatably connected inside the connecting ring 12. The surface of the heat-conducting cylinder 9 has evenly distributed insertion holes matching the size of the digestion tube. The surface of the sliding rod 6 is provided with a groove for inserting the digestion tube. A sealing cap 11 is used to seal the top of the digestion tube. A drive mechanism for rotating the heat-conducting cylinder 9 is provided on the surface of the connecting ring 12. A mounting bracket 3 is fixedly installed on the top of the digestion instrument body 1. A fan 4 is provided on the surface of the mounting bracket 3. During use, the digestion tube can be directly inserted into the insertion hole on the surface of the heat-conducting cylinder 9. Then, the water and reagent to be tested are poured into the inside. Multiple digestion tubes can be placed for use as needed. Then, the sealing cap 11 on the slide rod 6 is used to directly seal each digestion tube. Then, the first electric telescopic rod 7 is activated. The first electric telescopic rod 7 drives the entire slide rod 6 to slide downward, thereby driving the connecting ring 12 and the heat-conducting cylinder 9 to slide downward until the heat-conducting cylinder 9 is fully inserted. The heating sleeve 2 is located inside the digester body 1. The digester body 1 is then operated to heat the heating sleeve 2 to the required temperature and control the heating time. The heat is transferred to the digestion tube using the heat-conducting cylinder 9, thereby digesting the reagent inside. During the heating process, the entire heat-conducting cylinder 9 can be rotated using a drive mechanism to improve heating uniformity. After digestion is completed, the first electric telescopic rod 7 can be used to move the sliding rod 6 upward, thereby moving the entire connecting ring 12 and the heat-conducting cylinder 9 upward. Then, the fan 4 can be activated to blow air and dissipate heat from the entire heat-conducting cylinder 9. The heat of the heat-conducting cylinder 9 and the digestion tube is transferred to each other, thus achieving the purpose of cooling the digestion tube. Compared to the traditional method of manually removing the digestion tubes after digestion and placing them on a rack to cool down, this device eliminates the need for manual removal and cooling after high-temperature heating. Furthermore, compared to traditional methods of heating the digestion tubes, this device allows for more uniform heating, and the use of a fan 4 accelerates cooling, improving work efficiency. Traditional digestion apparatus requires a separate cap to cover the entire digestion tube and digestion area from the top during digestion; this device eliminates the need for a separate cap. Moreover, while traditional methods require individual caps on each digestion tube, this device eliminates the need for individual caps on each tube, making it more convenient to use.

[0027] Furthermore, a crossbar 10 is slidably connected to the surface of the slide bar 6, and a second electric telescopic rod 8 is fixedly installed at the top of the slide bar 6. The output end of the second electric telescopic rod 8 is fixedly connected to the crossbar 10. The sealing cover 11 is rotatably connected to the bottom of the crossbar 10. In use, when the second electric telescopic rod 8 is activated, the second electric telescopic rod 8 drives the crossbar 10 to move, and the crossbar 10 drives the sealing cover 11 to move synchronously, thereby achieving the purpose of sealing the digestion tube or moving it away from the digestion tube.

[0028] Furthermore, the bottom of the sealing cap 11 is evenly provided with grooves that match the size of the top of the digestion tube. A limiting block 16 is fixedly installed at the center of the bottom of the sealing cap 11. A limiting hole that matches the size of the limiting block 16 is provided at the center of the top of the heat-conducting cylinder 9. By setting the limiting block 16, when the sealing cap 11 needs to seal the digestion tube, the limiting block 16 will be inserted into the limiting hole. This allows the entire sealing cap 11 to rotate synchronously when the driving mechanism drives the heat-conducting cylinder 9 to rotate, so that the digestion tube is always in a sealed state.

[0029] Furthermore, the drive mechanism includes a motor 14, which is fixedly mounted on the surface of the connecting ring 12. A gear ring 13 is fixedly sleeved on the surface of the heat-conducting cylinder 9. The motor 14 is fixedly mounted on the surface of the connecting ring 12. A gear 15 is fixedly mounted on the output shaft port of the motor 14. The gear 15 and the gear ring 13 mesh. In use, when the drive mechanism is started, the motor 14 drives the gear 15 to rotate, the gear 15 drives the gear ring 13 to rotate, and the gear ring 13 drives the heat-conducting cylinder 9 to rotate within the connecting ring 12.

[0030] Furthermore, the depth of the insertion hole on the surface of the heat-conducting cylinder 9 is less than the length of the digestion tube so that the tube opening is exposed after the digestion tube is inserted, making it convenient to remove the digestion tube from the insertion hole of the heat-conducting cylinder 9.

[0031] Furthermore, the bottom groove of the sealing cap 11 is provided with a sealing gasket so that the top of the digestion tube can be sealed after being inserted into the groove.

[0032] In summary, during use, the digestion tube can be directly inserted into the insertion hole on the surface of the heat-conducting cylinder 9. Then, the water and reagent to be tested are poured into the interior. Multiple digestion tubes can be placed for use as needed. Then, the sealing cap 11 on the slide rod 6 is used to seal each digestion tube directly. Then, the first electric telescopic rod 7 is activated, which drives the entire slide rod 6 to slide downward, thereby driving the connecting ring 12 and the heat-conducting cylinder 9 to slide downward until the heat-conducting cylinder 9 is completely inserted into the heating sleeve 2 of the digester body 1. Then, the digester body 1 is operated to heat the heating sleeve 2 to the required temperature and control the heating time, using the heat-conducting cylinder 9... Heat is transferred to the digestion tube to digest the reagents inside. During heating, a drive mechanism rotates the entire heat-conducting cylinder 9 to improve heating uniformity. After digestion, the first electric telescopic rod 7 moves the sliding rod 6 upward, thereby moving the entire connecting ring 12 and heat-conducting cylinder 9 upward. Then, the fan 4 is activated to blow air onto the entire heat-conducting cylinder 9 for heat dissipation. The heat is transferred between the heat-conducting cylinder 9 and the digestion tube, thus achieving the purpose of cooling the digestion tube. Compared to the traditional method of manually removing the digestion tube after digestion and placing it on a rack to cool it down, this device eliminates the need for manual removal and placement on a rack for cooling. The digestion tubes need to be manually removed for heat dissipation after high-temperature heating. Compared to traditional methods of heating digestion tubes, this device allows for more uniform heating, and the fan 4 accelerates cooling, improving work efficiency. Traditional digestion apparatus 1 requires a separate cover to completely cover the digestion tubes and digestion area from the top during digestion. This device eliminates the need for a separate cover. Furthermore, while traditional digestion processes require individual caps on each digestion tube, this device eliminates the need for individual caps on each tube, making it more convenient to use. During use, the sealing cap 11 activates the second electric telescopic rod 8. The telescopic rod 8 drives the crossbar 10 to move, and the crossbar 10 drives the sealing cover 11 to move synchronously, thereby achieving the purpose of sealing the digestion tube or moving it away from the digestion tube. By setting the limiting block 16, when the sealing cover 11 needs to seal the digestion tube, the limiting block 16 will be inserted into the limiting hole, so that when the drive mechanism drives the heat-conducting cylinder 9 to rotate, the entire sealing cover 11 can rotate synchronously, so that the digestion tube is always in a sealed state. In use, the drive mechanism starts the motor 14, the motor 14 drives the gear 15 to rotate, the gear 15 drives the gear ring 13 to rotate, and the gear ring 13 drives the heat-conducting cylinder 9 to rotate in the connecting ring 12.
