Description

Technical Field

[0001] This application relates to the field of heating digestion, and more specifically, to a porous constant temperature bath digester. Background Technology

[0002] A water bath digester is a laboratory device that integrates water bath heating, automatic temperature control, and reflux circulation. It uses different heat media and a precise temperature control system to provide a constant heating environment for samples. Different heating temperatures cause organic and inorganic substances in the samples to react with the digesting agent, transforming them into soluble substances. It is widely used in environmental monitoring, food testing, pharmaceuticals, mineral product testing, and many other fields.

[0003] Chinese patent application number 202122769646.4 discloses a constant-temperature heating digestion apparatus, including a constant-temperature digestion apparatus with a cooler installed on its bottom side. After digestion, the cooler generates cold air, which extends into the interior of the constant-temperature digestion apparatus through a connecting pipe. An air blower is activated to deliver the cold air transported on the connecting pipe to a dispersion plate. The dispersion plate cools the digestion solution placed in the storage chamber, facilitating its removal and cooling. During cooling, an air intake fan extracts the cold air that has passed through the digestion solution, outputting it through an outlet pipe and a vent. The outlet pipe is spirally arranged to increase the output speed. A guide plate rotates on the surface of the constant-temperature digestion apparatus to guide the position and angle of the output cold air and facilitates the closure and protection of the vent. Both the air blower and intake fan have motor protection devices to prevent them from being affected or damaged, ensuring normal operation.

[0004] The above solution has the following shortcomings: When in use, the test tube containing the sample is supported by the opening at the top. However, the existing device has limited hole positions and diameters, and can only support test tubes or beakers of the corresponding model. Therefore, it needs to be improved. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a multi-pore constant temperature bath digester, which aims to improve the problem that the existing constant temperature bath digesters have limited pore size and thus have limitations.

[0006] This application provides a multi-position constant temperature bath digester, including a base for supporting the control console and the digestion shell. The top of the digestion shell is provided with a constant temperature bath, and a rotatable pressing and limiting plate is provided above the constant temperature bath. The connecting end of the pressing and limiting plate and the constant temperature bath is provided with a connecting shaft. A heating panel is limited between the pressing and limiting plate and the constant temperature bath, and a limiting insertion hole is provided on the surface of the heating panel.

[0007] In one specific implementation, the bottom surface of the heating panel is disposed on a recessed plate, and the recessed plate is inserted into the inner top of the thermostatic bath.

[0008] In the above implementation process, the connection between the heating panel and the digestion shell is made tighter through the plug-in structure, which further prevents the heating panel from loosening under long-term use or vibration environment.

[0009] In one specific implementation, the limiting insertion hole is provided in two sets, one set being a circular base for supporting the test tube, and the other set being a flat base for supporting the beaker.

[0010] In the above implementation process, by using two sets of limiting holes, namely a circular base for test tubes and a flat base for beakers, the equipment can simultaneously meet the usage requirements of different types of digestion containers such as test tubes and beakers, thereby improving the equipment's versatility and applicable scenarios. It can process samples of different specifications without the need to replace the special panel.

[0011] In one specific implementation, the side of the pressing limiting plate is provided with an extension plate, wherein the surface of the extension plate is provided with a perforation, and the top of the disintegration shell is provided with a lock hole, wherein a locking rod that can limit the position is inserted into the lock hole and the interior of the perforation.

[0012] In the above implementation process, the plug-in design of the locking rod makes operation simple, and the staff can quickly lock and unlock the pressing limit plate, which not only ensures the fixing effect, but also does not increase the complexity of operation and improves the efficiency of equipment use.

[0013] In one specific implementation, the top surface of the heating panel is provided with a pressure relief valve, wherein the pressure relief valve is connected to the interior of the thermostatic bath.

[0014] In the above process, during the heating process of the constant temperature bath, the internal heating medium may generate steam due to the increase in temperature, which will cause the pressure inside the bath to rise. The pressure relief valve can monitor the pressure inside the bath in real time. When the pressure exceeds the safety threshold, it will automatically open to relieve pressure, so as to avoid the constant temperature bath from deforming, leaking or even bursting due to excessive pressure, and ensure the safety of equipment and operators.

[0015] In one specific implementation, the digestion shell is provided with at least two thermostatic baths, wherein each thermostatic bath has a heating base at its bottom and a drain valve extending to the outside on one side of each thermostatic bath.

[0016] In the above implementation process, by setting at least two constant temperature baths, and each bath is independently equipped with a heating base at the bottom, the equipment can digest multiple groups of samples at the same time. Different temperature parameters can be set for each group of samples according to the requirements, which improves the sample processing efficiency and is especially suitable for batch sample analysis scenarios.

[0017] In one specific implementation, the top of the console is provided with a display panel and a control panel, wherein the heating base is electrically connected to the console.

[0018] In the above implementation process, the current temperature and set temperature of each constant temperature bath can be displayed in real time through the display panel on the top of the control console, which makes it convenient for staff to intuitively monitor the digestion process. The control panel can realize operations such as temperature setting, heating start and stop, and constant temperature duration adjustment. Combined with the electrical connection between the heating base and the control console, the temperature control accuracy is ensured to meet the requirements of high-precision digestion reaction.

[0019] In one specific implementation, a replenishment tank is provided on the side of the digestion shell, wherein a replenishment pump is provided at the bottom of the replenishment tank and a liquid inlet is provided on the back of the replenishment tank, and a replenishment pipe extending into the constant temperature bath is provided on the side of the replenishment tank, wherein the replenishment pipe is connected to the replenishment pump.

[0020] In the above process, the replenishment tank is connected to the constant temperature bath via a replenishment pump and a replenishment pipe. When the heating medium in the constant temperature bath decreases due to evaporation, leakage or other reasons, the replenishment pump can actively replenish the bath to avoid the heating base from burning dry or the constant temperature effect from failing due to insufficient medium, thus ensuring the continuous and stable operation of the equipment.

[0021] In one specific implementation, the thermostatic bath is equipped with a liquid level sensor, which is electrically connected to the replenishment pump of the replenishment tank.

[0022] In the above process, the liquid level sensor in the constant temperature bath can monitor the liquid level of the heating medium in real time. When the liquid level is lower than the set lower limit, the sensor immediately sends a signal to the replenishment pump to trigger automatic replenishment. When the liquid level reaches the set upper limit, the replenishment stops automatically, realizing unattended intelligent replenishment. This eliminates the need for staff to frequently check the liquid level, reducing labor costs and avoiding the problem of insufficient medium caused by human negligence.

[0023] In one specific implementation, the heating medium inside the thermostatic bath is water, glycerin, or silicone oil, etc.

[0024] In the above process, different heating media have different boiling points, thermal conductivity, and applicable temperature ranges. Water is suitable for low-temperature digestion, while media such as glycerol and silicone oil are suitable for higher-temperature digestion. This covers a variety of digestion needs from room temperature to high temperature, making the equipment adaptable to different samples, such as the digestion reaction temperature requirements of organic and inorganic substances, and improving the applicability of the equipment.

[0025] Compared with the prior art, the beneficial effects of this application are as follows:

[0026] 1. This application, through a perforated plate with replaceable holes of different diameters, and the precise insertion of the recessed plate on the bottom of the perforated plate into the constant temperature bath, can stably support test tubes or beakers of various specifications, solving the limitations of use caused by the fixed hole positions and diameters of traditional devices, and meeting the carrying requirements of different experimental samples.

[0027] 2. In this application, two independent constant temperature baths are equipped with bottom heating bases to achieve independent temperature control of each bath, and multiple sets of samples can be processed at the same time; the liquid level sensor and submersible pump are linked to achieve automatic liquid replenishment, and the pressure limiting plate is fixed by locking rod to ensure the stability of the orifice plate, thus ensuring the accuracy and stability of the digestion process.

[0038] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0039] Please see Figure 1-8 This application provides a multi-position constant temperature bath digester, including a base 1 for supporting the control console 2 and the digestion shell 3. A replenishment tank 4 is provided on the side of the digestion shell 3. The replenishment tank 4 is made of corrosion-resistant plastic to prevent corrosion from acid mist. A replenishment pump is installed at the bottom of the replenishment tank 4, providing stable liquid delivery. A liquid inlet 41 is provided on the back of the replenishment tank 4, equipped with a sealing cap to prevent the heating medium from evaporating or external impurities from entering. A replenishment pipe 42 extending into the constant temperature bath 37 is provided on the side of the replenishment tank 4. The replenishment pipe 42 is made of high-temperature and corrosion-resistant silicone tubing and is connected to the replenishment pump. The replenishment tank 4 is connected to the constant temperature bath 37 via the replenishment pump and the replenishment pipe 42. When the heating medium in the constant temperature bath 37 decreases due to evaporation, leakage, or other reasons, the replenishment pump can actively replenish the bath, preventing the heating base 23 from drying out or the constant temperature effect from failing due to insufficient medium, thus ensuring continuous and stable operation of the equipment.

[0040] The top of the control console 2 is equipped with a display panel 21 and a control panel 22. The display panel 21 is a high-definition LCD screen that can clearly display various parameters. The heating base 23 is electrically connected to the control console 2. The heating base 23 is made of high-quality electrothermal alloy material, which has good thermal conductivity and uniform heating. The display panel 21 on the top of the control console 2 can display parameters such as the current temperature and set temperature of each constant temperature bath 37 in real time, which is convenient for staff to intuitively monitor the digestion process. The control panel 22 is equipped with multiple function buttons and knobs, which can realize operations such as temperature setting, heating start / stop, and constant temperature duration adjustment. Combined with the electrical connection between the heating base 23 and the control console 2, it ensures the accuracy of temperature control and meets the requirements of high-precision digestion reaction.

[0041] The top of the digestion shell 3 is provided with a constant temperature bath 37. The constant temperature bath 37 is equipped with a liquid level sensor 43, which can accurately detect changes in liquid level. The liquid level sensor 43 is electrically connected to the replenishment pump of the replenishment tank 4. The liquid level sensor 43 in the constant temperature bath 37 can monitor the liquid level of the heating medium in real time. When the liquid level is lower than the set lower limit, the sensor immediately sends a signal to the replenishment pump to trigger automatic replenishment. When the liquid level reaches the set upper limit, the replenishment stops automatically, realizing unattended intelligent replenishment. There is no need for staff to frequently check the liquid level, reducing labor costs and avoiding the problem of insufficient medium caused by human negligence.

[0042] The heating medium inside the constant temperature bath 37 is water, glycerin, or silicone oil. Different heating media have different boiling points, thermal conductivity, and applicable temperature ranges. Water is suitable for low-temperature digestion, while glycerin, silicone oil, and other media are suitable for higher-temperature digestion. This covers a variety of digestion needs from room temperature to high temperature, making the equipment adaptable to different samples, such as the digestion reaction temperature requirements of organic and inorganic substances, thus improving the applicability of the equipment.

[0043] The digestion shell 3 is equipped with at least two thermostatic baths 37, each of which has a heating base 23 at its bottom. Each thermostatic bath 37 also has a drain valve 38 extending to the outside on one side. The drain valve 38 is a corrosion-resistant ball valve, which facilitates the rapid discharge of the heating medium. By setting at least two thermostatic baths 37, and each bath having an independent heating base 23 at its bottom, the equipment can digest multiple groups of samples simultaneously. Different temperature parameters can be set for each group of samples according to requirements, improving sample processing efficiency, which is especially suitable for batch sample analysis scenarios.

[0044] Furthermore, a rotatable pressing and limiting plate 32 is provided above the constant temperature bath 37. The pressing and limiting plate 32 is made of metal and has a certain strength. A connecting shaft 31 is provided at the connection end between the pressing and limiting plate 32 and the constant temperature bath 37. The connecting shaft 31 is made of stainless steel and rotates smoothly. An extension plate 34 is provided on the side of the pressing and limiting plate 32. The extension plate 34 and the pressing and limiting plate 32 are integrally formed. The surface of the extension plate 34 is provided with a perforation, and the top of the digestion shell 3 is provided with a locking hole 35, which corresponds to the position of the perforation. A locking rod 39 that can limit the position is inserted into the locking hole 35 and the inside of the perforation. The locking rod 39 is a metal rod with a smooth surface for easy insertion and removal. The plug-in design of the locking rod 39 makes operation simple. The operator can quickly lock and unlock the pressing and limiting plate 32, which not only ensures the fixing effect but also does not increase the complexity of operation and improves the efficiency of equipment use.

[0045] A heating panel 5 is positioned between the pressing and limiting plate 32 and the constant temperature bath 37. The heating panel 5 is made of a high-temperature resistant and corrosion-resistant alloy material. The surface of the heating panel 5 is provided with limiting holes 52. There are two sets of limiting holes 52. One set is a circular base for supporting test tubes. The diameter of the circular base is adapted to the outer diameter of common test tubes. The other set is a flat base for supporting beakers. The size of the flat base can be adapted to the bottom of beakers of different specifications. With two sets of limiting insertion holes 52, one for a circular base and one for a flat base, the device can simultaneously meet the needs of different types of digestion containers such as test tubes and beakers, improving the device's versatility and applicable scenarios. It can process samples of different specifications without changing the special panel. In addition, to ensure that the heating medium in the constant temperature bath 37 is heated more evenly, each constant temperature bath 37 has a magnetic stirring rod, and a magnetic stirrer is provided at the bottom of the constant temperature bath 37. The magnetic stirrer is electrically connected to the control panel 2, and the stirring speed can be adjusted through the control panel 22 to achieve the stirring function, allowing the heating medium to flow fully in the bath, further improving temperature uniformity and ensuring consistent sample digestion effect.

[0046] The bottom surface of the heating panel 5 is set on the recessed plate 51. The recessed plate 51 and the heating panel 5 are integrally formed. The recessed plate 51 is inserted into the inner top of the constant temperature bath 37. The insertion structure makes the connection between the heating panel 5 and the digestion shell 3 tighter, further preventing the heating panel 5 from loosening in long-term use or under vibration environment, and extending the service life of the equipment.

[0047] The top surface of the heating panel 5 is equipped with a pressure relief valve 53, which is an automatic pressure control valve with precise pressure sensing and pressure relief capabilities. The pressure relief valve 53 is connected to the inside of the thermostatic bath 37. During the heating process, the heating medium inside the thermostatic bath 37 may generate steam due to the increase in temperature, which will cause the pressure inside the bath to rise. The pressure relief valve 53 can monitor the pressure inside the bath in real time. When the pressure exceeds the safety threshold, it will automatically open to relieve pressure, so as to avoid the thermostatic bath 37 from deforming, leaking or even bursting due to excessive pressure, and ensure the safety of equipment and operators.

[0048] The working principle of this multi-position constant temperature bath digester is as follows: Heating medium is injected into the replenishment tank 4 through the replenishment port 41. With the help of the replenishment pump and replenishment pipe 42, combined with the liquid level monitoring by the liquid level sensor 43 in the constant temperature bath 37, the heating medium in the constant temperature bath 37 is automatically replenished. Then, the temperature and other parameters of the heating base 23 at the bottom of each constant temperature bath 37 are set using the control panel 22 of the console 2. The display panel 21 displays the relevant data in real time. The heating base 23 heats the medium in the constant temperature bath 37. If more uniform heating is required, the heating medium can be adjusted by... The magnetic stirrer at the bottom of the thermostatic bath 37 drives the magnetic stirring rod inside the bath to stir. Then, test tubes or beakers containing the sample are placed into the limiting holes 52 of the heating panel 5. The limiting plate 32 is rotated and pressed, and the locking rod 39 is passed through the hole of the extension plate 34 and locked with the locking hole 35 of the digestion shell 3 to complete the fixation. During the digestion process, the pressure relief valve 53 inside the thermostatic bath 37 monitors and releases excessive pressure in real time to ensure safety. Multiple thermostatic baths 37 can process samples with different temperature requirements at the same time. After digestion is completed, the heating medium is discharged through the discharge valve 38.

[0049] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
