Abstract
Description
Technical Field
[0001] The present application relates to the technical field of water digestion and exhaust, and specifically to a digestion device. Background Art
[0002] Digestion devices are primarily used to degrade difficult-to-measure substances, converting them into easily detectable compounds or ions. They are often used in environmental monitoring to pre-treat samples. Based on the digestion principle, they can be divided into electrothermal and microwave digestion devices. Microwave digestion devices are primarily used for heavy metal analysis and degradation of heavy metals in various media. Electrothermal digestion devices can be used for various media and analyses requiring thermal decomposition, such as the degradation of COD, total nitrogen, and total phosphorus.
[0003] In order to improve the accuracy of water quality test results, the water sample needs to be digested first. The role of digestion is to use acidic liquid to destroy the organic matter and reducing substances in the water sample to be tested at a certain temperature, making it a measurable part. However, since a large amount of high-temperature gas will be generated during the digestion reaction, the pressure in the digestion tank will increase. The digestion tank is sealed, and the continuous increase in pressure may cause safety problems such as rupture or explosion of the tank. Therefore, we proposed a digestion device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0022] Example
[0023] See also Figure 1-4 , a digestion device includes a digestion bin 1, a pressure gauge 5 is installed on the outer wall of the digestion bin 1, an exhaust pipe 4 is installed at the top of the digestion bin 1, two support plates 2 are symmetrically fixedly installed on the top of the digestion bin 1, the tops of the two top plates 3 are fixedly connected through the top plate 3, the top of the exhaust pipe 4 is tightly fitted with a pressure plate 8, and a sealing ring 9 is fixedly installed on the bottom end of the pressure plate 8. A plurality of through holes 13 are opened on the outer wall of the sealing ring 9. By opening the through holes 13, a plurality of limiting plates 14 are fixedly installed on the opposite surfaces of the two support plates 2, and the outer wall of each limiting plate 14 is fitted with the sliding slide 7. By installing the limiting plate 14, the sliding slide 7 is limited.
[0024] See also Figure 1-4 The top of slide plate 7 is fitted with a moving block 12, and a screw 11 is rotatably installed on the top of the moving block 12. The screw 11 is screwed with the fixed plate 6 and the top plate 3 respectively. The digestion device is convenient for releasing the increased air pressure inside the digestion bin 1 through the exhaust pipe 4, and the top of the exhaust pipe 4 is sealed by the pressure plate 8 and the sealing ring 9. By rotating the screw 11, the slide plate 7 is moved by the moving block 12, thereby adjusting the expansion coefficient of the spring 10, thereby facilitating the adjustment operation according to different release pressures, facilitating the release operation of the enhanced air pressure inside the digestion bin 1, effectively protecting the digestion bin 1, extending the service life of the digestion bin 1, and improving practicality.
[0025] See also Figure 2 It should also be noted that a handle 15 is fixedly installed on the top of the screw rod 11. By installing the handle 15, it is convenient for the user to rotate the screw rod 11.
[0026] See also Figure 1 A door 16 is rotatably mounted on the outer wall of the digestion chamber 1 , and the components inside the digestion chamber 1 can be inspected and maintained by installing the door 16 .
[0027] See also Figure 1 A plurality of pillars 17 are fixedly installed around the bottom of the digestion chamber 1. By installing the pillars 17, the device can be easily supported.
[0028] In summary, when the digestion device is in use, the door 16 is opened, and the water to be digested is moved, the water is digested through the digestion chamber 1, and the air pressure inside the digestion chamber 1 is observed through the barometer 5. Since the screw 11 and the top plate 3 are screwed together with the fixed plate 6, the screw 11 is synchronously driven to rotate while rotating the handle 15. The moving block 12 is synchronously driven by the rotation of the screw 11 to squeeze the slide 7, and the sliding slide 7 is limited by the limit plate 14, and then the spring 10 is compressed or the extension coefficient is adjusted. When the reaction pressure inside the digestion chamber 1 is large, the gas from the exhaust pipe 4 lifts the pressure plate 8 and the sealing ring 9, and can be discharged through the through hole 13 opened on the sealing ring 9.
