Description

Technical Field

[0001] The present invention belongs to the technical field of element analysis test digestion equipment, and particularly relates to a high-throughput electrothermal digester. Background Art

[0002] An electrothermal digester is an instrument that uses high-temperature and high-pressure steam to convert organic or inorganic substances in a sample into atomic or ionic states for easy analysis and measurement. Its principle is based on the thermal decomposition of the sample and the digestion by steam. In an electrothermal digester, the sample is heated to a specific temperature so that the organic or inorganic substances in the sample can be thermally decomposed and dissolved in the heated water. With the development of testing technologies, the sample pretreatment digestion technology has become particularly important and prominent, which determines the efficiency and accuracy of test data.

[0003] Currently, there are mainly 4 digestion methods: 1. The open digestion method, which uses a large amount of acid, has a high blank value, a very high probability of external contamination, seriously corrodes the laboratory fume hood and hot plate, and there is a phenomenon that the sample is not completely digested; 2. The ordinary closed digestion method, which can withstand low pressure, is not safe enough for the digestion of biological samples, is prone to explosion tank phenomenon, has a long digestion time, is difficult to digest some insoluble samples, and has a low recovery rate for some high-field-strength elements, thus polluting the environment. 3. The microwave digestion method, which cannot effectively digest some high-field-strength elements and the pressure it can withstand is much lower than that of a high-pressure digestion tank. 4. It is the traditional high-pressure closed digestion method, which mainly uses a high-pressure reaction kettle for digestion. The acid is easy to leak, corrodes the stainless steel tank body and the heating oven, affects the service life, the acid is easy to volatilize, the digestion is unstable, the buckling is complex, and it is relatively bulky.

The front end of the waste water tank 8 is fixed with a water outlet pipe 801. The water outlet pipe 801 is made of flexible material. The right end of the water outlet pipe 801 is fixed with a water outlet valve 802.

[0060] Advantageously, the waste water valve 804 and the waste water pump 803 cooperate to transport the waste liquid inside the purification box 3 to the waste water tank 8. The water outlet pipe 801 facilitates the output of the waste liquid inside the waste water tank 8, and the water outlet valve 802 can control the output of the waste liquid inside the waste water tank 8.

[0061] The back end of the purification box 3 is provided with a dehumidification box door 901. The dehumidification box door 901 is fixedly connected to the dehumidification box 9 through bolts. Inside the dehumidification box 9, there is a drying plate 906. In front of the drying plate 906, there is an activated carbon adsorption plate 907. Inside the air outlet box 903, there is a humidity sensor 904 fixed. On the left side of the humidity sensor 904, there is an acid-base concentration sensor 905 fixed.

[0062] Beneficially, the dehumidification chamber door 901 can ensure the sealing of the dehumidification chamber 9. The drying plate 906 is used to dry the air inside the purification chamber 3.

The humidity sensor 904 is used to monitor the dryness and humidity of the gas output from the dehumidification chamber 9. The acid-base concentration sensor 905 is used to monitor the pH value of the gas output from the dehumidification chamber 9.

[0063] When reducing the temperature inside the digestion chamber 111, the control panel 103 controls the exhaust gas pump 302 and the exhaust gas valve 303 to work simultaneously. As a result, while cold air enters the digestion chamber 111, the acidic gas leaked from the digestion chamber 111 due to digestion is transported through the exhaust gas outlet 304 to the exhaust gas pipe 301, and then to the inside of the purification chamber 3. At this time, the control panel 103 controls the neutralizing liquid valve 401 and the neutralizing liquid pump 402 to work, so as to transport the alkaline solution to the ultrasonic atomizer 5. Then, the ultrasonic atomizer 5 atomizes the alkaline solution. Further, the control panel 103 controls the atomized liquid pump 501 and the atomized liquid valve 502 to work, so as to transport the atomized alkaline liquid through the atomized liquid pipe 503 to the atomized liquid nozzle 504, so as to humidify and neutralize the acidic gas transported from the exhaust gas pipe 301 to the inside of the purification chamber 3. At this time, the control panel 103 controls the waste water pump 803 and the waste water valve 804 to work, so as to pump the neutralized waste liquid inside the purification chamber 3 to the waste water tank 8.

[0064] Furthermore, the gas neutralized inside the purification chamber 3 is transported to the inside of 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 can be adsorbed while the gas is dried, and then further transported to the inside of the air outlet chamber 903. At this time, the control panel 103 can monitor the humidity and pH value of the purified gas inside the air outlet chamber 903 through the humidity sensor 904 and the acid-base concentration sensor 905. If the purified gas meets the emission standards, the purified gas is directly discharged into the environment, thus realizing green, environmentally friendly, high-throughput and efficient digestion. If the pH value and humidity are unqualified, the control panel 103 will alarm. Further, the staff replaces the drying plate 906 and the activated carbon adsorption plate 907, and at the same time adjusts the atomized liquid valve 502 to control the neutralization accuracy. When the temperature reduction is completed, the staff opens the lower chamber door 101, and further opens the water outlet valve 802 to collect the waste liquid, so as to prevent the waste liquid from polluting the environment.

[0065] The working process of the present invention is as follows: Before using this device, the staff places the digestion instrument 1 in the required position. Further, the staff electrically connects the power cord 104 to an external power source. Further, the staff opens the control panel 103 to control the contraction of the locking rod 113, thereby driving the locking plate 115 to move to the right, thereby driving the locking block 112 to move to the right, so that the upper box door 102 is disengaged. Further, the staff opens the upper box door 102. At this time, the staff places a plurality of digestion tanks 119 filled with acid solution inside into the digestion unit 108. Further, the staff closes the upper box door 102. Further, the control panel 103 controls the reset of the locking rod 113. At this time, due to the action of the locking spring 116 and the locking slide rod 117, the locking block 112 is snapped into the right end slot of the upper box door 102, thereby preventing the upper box door 102 from opening, thus ensuring the sealing performance of the device. At this time, the control panel 103 controls the air pump 7 and the air valve 701 to work, so that external air enters the digestion instrument 1 through the gas filter screen 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 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 708 to rotate, thereby driving the cleaning wire 709 to rotate, so as to prevent the filter plate 707 from being blocked. At this time, the air is transported to the heating chamber 703 through the air inlet pipe 702. Further, the control panel 103 controls the heater 705 and the heating plate 706 to work, so as to heat the air inside the heating chamber 703, and then transport it to the air delivery pipe 2 through the air inlet pipe 702, and then output it to the digestion chamber 111 through the air outlet head 204, so as to heat the digestion chamber 111, thereby accelerating digestion. At this time, the temperature sensor 118 transmits the temperature information inside the digestion chamber 111 to the control panel 103. At the same time, the control panel 103 controls the reversing motor 201 to work, thereby driving the air delivery pipe 2 to rotate, so as to ensure the uniformity of heating, thus ensuring the heating effect, and thus ensuring the accuracy and stability of digestion. When digestion is carried out for a certain period of time, the control panel 103 controls the heater 705 to stop working, and at the same time controls the air pump 7 and the air valve 701 to stop working. Further, the control panel 103 controls the compressor 6 to work, so as to cool the external air, and then transport the cold air to the air inlet pipe 702 through the cold air pump 601 and the cold air valve 603, and then output it through the air outlet head 204, so as to reduce the temperature inside the digestion chamber 111. At the same time, the control panel 103 controls the reversing motor 201 to work again,Thus, the digestion chamber 111 is cooled evenly. At the same time, the control panel 103 controls the waste gas pump 302 and the waste gas valve 303 to work simultaneously, so that cold air enters the interior of the digestion chamber 111 while the acidic gas leaked due to digestion in the interior of the digestion chamber 111 is transported to the waste gas pipe 301 through the waste gas outlet 304, and then transported to the interior of the purification tank 3. At this time, the control panel 103 controls the neutralizing liquid valve 401 and the neutralizing liquid pump 402 to work, so as to transport the alkaline solution to the ultrasonic atomizer 5. Then, the ultrasonic atomizer 5 atomizes the alkaline solution. Further, the control panel 103 controls the atomized liquid pump 501 and the atomized liquid valve 502 to work, so as to transport the atomized alkaline liquid through the atomized liquid pipe 503 to the atomized liquid nozzle 504, so as to humidify and neutralize the acidic gas transported from the waste gas pipe 301 to the interior of the purification tank 3. At this time, the control panel 103 controls the waste water pump 803 and the waste water valve 804 to work, so as to pump the neutralized waste liquid in the interior of the purification tank 3 to the waste water tank 8. Further, the gas neutralized in the interior of the purification tank 3 is transported to the interior of the dehumidification tank 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-base solution in the air in the interior of the dehumidification tank 9 can be adsorbed while the gas is dried, and then transported to the interior of the air outlet tank 903. At this time, the control panel 103 can monitor the humidity and pH value of the purified gas in the interior of the air outlet tank 903 through the humidity sensor 904 and the acid-base concentration sensor 905. If the purified gas meets the emission standard, the purified gas is directly discharged into the environment, thus realizing green, environmentally friendly, high-throughput and efficient digestion. If the pH value and humidity are unqualified, the control panel 103 gives an alarm. Further, the staff replaces the drying plate 906 and the activated carbon adsorption plate 907, and at the same time adjusts the atomized liquid valve 502 to control the neutralization accuracy. When the digestion chamber 111 cools down to room temperature, the control panel 103 controls the compressor 6 to stop working. Further, the control panel 103 controls the upper box door 102 to open, so that the digested digestion tank 119 can be taken out. Further, the staff opens the lower box door 101, and further opens the water outlet valve 802, so as to collect the waste liquid, thus preventing the waste liquid from polluting the environment.,
