Description

Technical Field

[0001] This utility model belongs to the technical field of elemental analysis and testing digestion equipment, specifically relating to a high-throughput electrothermal digestion instrument. Background Technology

[0002] An electrothermal digestion apparatus is an instrument that uses high-temperature, high-pressure steam to convert organic or inorganic substances in a sample into atomic or ionic states for analysis and measurement. Its principle is based on the thermal decomposition of the sample and the digestion by steam. In an electrothermal digestion apparatus, the sample is heated to a specific temperature, causing the organic or inorganic substances within to thermally decompose and dissolve in heated water. With the development of testing technology, sample pretreatment and digestion techniques have become particularly important and prominent, determining the efficiency and accuracy of test data.

[0003] Currently, there are four main digestion methods: 1. Open-top digestion: This method uses a large amount of acid, has a high blank rate, and a very high chance of external contamination. It severely corrodes laboratory fume hoods and hot plates, and there is a possibility of incomplete sample digestion. 2. Conventional closed digestion: This method has low pressure tolerance, is not safe enough for digesting biological samples, is prone to container explosions, has a long digestion time, is difficult to digest some poorly soluble samples, has low recovery rates for some high field strength elements, and thus pollutes the environment. 3. Microwave digestion: This method cannot effectively digest some high field strength elements, and its pressure tolerance is far lower than that of high-pressure digestion vessels. 4. Traditional high-pressure closed digestion: This method mainly uses a high-pressure reactor for digestion. The acid is prone to leakage, corrodes the stainless steel tank and heating oven, affecting its service life, the acid is volatile, digestion is unstable, the assembly is complex, and it is relatively cumbersome.

[0052] Before using this equipment, the staff places the digester 1 in the required position, then connects it to an external power source via the power cord 104, and then controls the locking lever 113 to retract via the control panel 103, thereby moving the locking plate 115 to the right, which in turn moves the locking block 112 to the right, thus disengaging the upper door 102.

[0053] The operator then opens the upper chamber door 102 and places multiple digestion vessels 119, each containing acid solution, onto the digestion unit 108.

The control panel 103 then controls the air pump 7 and the air valve 701. The system operates so that external air enters the digester 1 through the gas filter 106 at the top. At this time, the control panel 103 controls the ventilation motor 203 to work, thereby causing the ventilation fan 202 to rotate, thus accelerating air circulation. The air then enters the air inlet pipe 702 through the filter plate 707. At this time, the control panel 103 controls the cleaning motor 710 to work, thereby driving the cleaning rod 708 to rotate, which in turn drives the cleaning wire 709 to rotate, thus preventing the filter plate 707 from clogging. At this time, the air is delivered to the heating chamber 703 through the air inlet pipe 702.

[0054] Furthermore, the control panel 103 controls the heater 705 and the heating plate 706 to operate, thereby heating the air inside the heating chamber 703. This heated air is then delivered to the air supply pipe 2 through the air inlet pipe 702, and then to the digestion chamber 111 through the air outlet 204, thus heating the digestion chamber 111 and accelerating digestion. At this time, the temperature sensor 118 transmits the temperature information inside the digestion chamber 111 to the control panel 103. Simultaneously, the control panel 103 controls the reversing motor 201 to operate, thereby driving the air supply pipe 2 to rotate, ensuring uniform heating, thus ensuring heating effect and the stability of digestion accuracy. After a certain digestion time, the control panel 103 controls the heater 705... The system stops operating, simultaneously controlling the air pump 7 and the air valve 701 to stop working. The control panel 103 then controls the compressor 6 to operate, thereby cooling the external air. The cooled air is then delivered through the cooling pipe 602 to the air inlet pipe 702 via the cooling pump 601 and the cooling valve 603, and output through the air outlet 204. This reduces the internal temperature of the digestion chamber 111. Simultaneously, the control panel 103 controls the reversing motor 201 to operate again, ensuring uniform cooling of the digestion chamber 111. When the digestion chamber 111 cools to room temperature, the control panel 103 controls the compressor 6 to stop working. Furthermore, the control panel 103 controls the upper door 102 to open, allowing the digestion container 119, which has undergone digestion, to be removed.

[0062] Beneficially, the dehumidification chamber door 901 ensures the airtightness of the dehumidification chamber 9, the drying plate 906 is used to dry the air inside the purification chamber 3, the activated carbon adsorption plate 907 is used to adsorb unreacted acid and alkali solutions in the gas inside the dehumidification chamber 9, the humidity sensor 904 is used to monitor the humidity of the gas output from the dehumidification chamber 9, and the acid and alkali concentration sensor 905 is used to monitor the acidity and alkalinity of the gas output from the dehumidification chamber 9.

[0063] While lowering the internal temperature of the digestion chamber 111, the control panel 103 simultaneously controls the exhaust gas pump 302 and the exhaust gas valve 303 to operate, allowing cold air to enter the digestion chamber 111. Simultaneously, acidic gas leaking from the digestion process inside the digestion chamber 111 is transported through the exhaust gas outlet 304 to the exhaust gas pipe 301, and then to the purification chamber 3. At this time, the control panel 103 controls the neutralization liquid valve 401 and the neutralization liquid pump 402 to operate, thereby delivering the alkaline solution to the ultrasonic atomizer 5. The ultrasonic atomizer 5 atomizes the alkaline solution, and the control panel 103 controls the atomizing liquid pump 501 and the atomizing liquid valve 502 to operate, thereby delivering the atomized alkaline liquid through the atomizing liquid pipe 503 to the atomizing liquid nozzle 504, thereby delivering the acidic gas inside the purification box 3 through the exhaust gas pipe 301 for humidification and neutralization. At this time, the control panel 103 controls the wastewater pump 803 and the wastewater valve 804 to operate, thereby pumping the neutralized waste liquid inside the purification box 3 into the wastewater tank 8.

[0064] Further, the neutralized gas inside the purification chamber 3 is transported to the dehumidification chamber 9 through the dehumidification pipe 902. At this time, due to the action of the drying plate 906 and the activated carbon adsorption plate 907, the unreacted acid and alkali solutions in the air inside the dehumidification chamber 9 are adsorbed while the gas is dried, and then transported to the exhaust chamber 903. At this time, the control panel 103 can monitor the humidity and pH of the purified gas inside the exhaust chamber 903 through the humidity sensor 904 and the acid and alkali concentration sensor 905. If the purified gas meets the emission standards, the purified gas is directly discharged into the environment, thereby achieving green, environmentally friendly, high-throughput, and efficient decontamination. If the pH and humidity are not up to standard, the control panel 103 will alarm, and the operator will replace the drying plate 906 and the activated carbon adsorption plate 907, and adjust the atomizing liquid valve 502 to control the neutralization accuracy. After cooling is completed, the operator opens the lower chamber door 101 and the water outlet valve 802 to collect the waste liquid, thereby preventing the waste liquid from polluting the environment.

[0065] The working process of this utility model is as follows: Before using this equipment, the operator places the digester 1 in the desired position. The operator then connects it to an external power source via the power cord 104. The operator then controls the locking lever 113 to retract via the control panel 103, thereby moving the locking plate 115 to the right, which in turn moves the locking block 112 to the right, causing the upper door 102 to disengage. The operator then opens the upper door 102 and places multiple digestion vessels 119, each containing acid solution, onto the digestion unit 108. The operator then closes the upper door 102, and the control panel 103 resets the locking lever 113. Due to the action of the locking spring 116 and the locking slide bar 117, the locking block 112 is engaged in the right end groove of the upper box door 102, thereby preventing the upper box door 102 from opening and ensuring the sealing of the equipment. At this time, the control panel 103 controls the air pump 7 and the air valve 701 to work, so that the outside air enters the digester 1 through the gas filter 106 at the top. At this time, the control panel 103 controls the ventilation motor 203 to work, so that the ventilation fan 202 rotates, thereby accelerating the air circulation, and then enters the air inlet pipe 702 through the filter plate 707. At this time, the control panel 103 controls the cleaning motor 710 to work, thereby driving the cleaning rod 7. The 08 rotates, thereby driving the cleaning wire 709 to rotate, thus preventing the filter plate 707 from clogging. At this time, air is delivered to the heating chamber 703 through the air inlet pipe 702. Furthermore, the control panel 103 controls the heater 705 and the heating plate 706 to work, thereby heating the air inside the heating chamber 703. The air is then delivered to the air supply pipe 2 through the air inlet pipe 702, and then delivered to the digestion chamber 111 through the air outlet 204, thereby heating the digestion chamber 111 and accelerating digestion. At this time, the temperature sensor 118 transmits the temperature information inside the digestion chamber 111 to the control panel 103. Simultaneously, the control panel 103 controls the reversing motor 20. The heating element 1 operates, thereby driving the air supply pipe 2 to rotate, ensuring uniform heating, thus guaranteeing heating effect and stable digestion accuracy. After a certain digestion time, the control panel 103 controls the heater 705 to stop working, and simultaneously controls the air pump 7 and the air valve 701 to stop working. Further, the control panel 103 controls the compressor 6 to operate, thereby cooling the external air. The cooled air is then delivered through the cooling pipe 602 to the inside of the air inlet pipe 702 via the cooling pump 601 and cooling valve 603, and then output through the air outlet 204, thereby reducing the internal temperature of the digestion chamber 111. Simultaneously, the control panel 103 controls the reversing motor 201 to start working again.This allows the digestion chamber 111 to cool down evenly. Simultaneously, the control panel 103 controls the exhaust gas pump 302 and the exhaust gas valve 303 to operate simultaneously. This allows cold air to enter the digestion chamber 111, while acidic gas leaking from the digestion process is transported through the exhaust gas outlet 304 to the exhaust gas pipe 301, and then to the purification chamber 3. At this time, the control panel 103 controls the neutralization liquid valve 401 and the neutralization liquid pump 402 to operate, thereby delivering the alkaline solution to the ultrasonic atomizer 5. The ultrasonic atomizer 5 then atomizes the alkaline solution... The solution is atomized, and then the control panel 103 controls the atomizing liquid pump 501 and the atomizing liquid valve 502 to operate, thereby transporting the atomized alkaline liquid through the atomizing liquid pipe 503 to the atomizing liquid nozzle 504, thereby transporting the acidic gas inside the purification tank 3 through the exhaust gas pipe 301 for humidification and neutralization. At this time, the control panel 103 controls the wastewater pump 803 and the wastewater valve 804 to operate, thereby pumping the neutralized waste liquid inside the purification tank 3 into the wastewater tank 8, and further, the neutralized gas inside the purification tank 3 is transported through the dehumidification pipe 902. The gas is then introduced into the dehumidification chamber 9. At this point, the drying plate 906 and the activated carbon adsorption plate 907 adsorb unreacted acid and alkali solutions in the air inside the dehumidification chamber 9 while simultaneously drying the gas. The gas is then further transported to the outlet chamber 903. The control panel 103 monitors the humidity and pH of the purified gas inside the outlet chamber 903 via the humidity sensor 904 and the acid / alkali concentration sensor 905. If the purified gas meets emission standards, it is directly discharged into the environment, thus achieving green, environmentally friendly, high-throughput, and efficient decontamination. If the pH and pH are low... If the humidity is not up to standard, the control panel 103 will sound an alarm. Further, personnel will replace the drying plate 906 and the activated carbon adsorption plate 907, and simultaneously adjust the atomizing liquid valve 502 to control the neutralization accuracy. When the digestion chamber 111 cools to room temperature, the control panel 103 will stop the compressor 6. The control panel 103 will then open the upper chamber door 102 to remove the digestion tank 119, which has completed digestion. Personnel will then open the lower chamber door 101 and the water outlet valve 802 to collect the waste liquid, thus preventing environmental pollution.
