Description

Technical Field

[0001] This utility model relates to the field of heating digesters, specifically to an intelligent constant temperature heating digester. Background Technology

[0002] Organic samples require preheating to release gases before closed microwave digestion, thus reducing the risk of overpressure explosions. However, current laboratory heaters can only provide preliminary preheating, and the heating process can easily dry out the sample, hindering precise experimental control. Furthermore, thermal expansion and contraction after heating can cause the digestion vessel to be difficult to remove promptly, resulting in prolonged heating. Additionally, prolonged heating can soften the PTFE digestion vessel, significantly impacting its lifespan. Currently available heaters do not meet the requirements of some experiments.

[0003] A heated digester is a device used for sample digestion and dissolution. It decomposes and dissolves organic and inorganic substances in the sample by heating the sample and a chemical solvent. This device has wide applications in environmental analysis, food safety, pharmaceutical research and development, and the petrochemical industry.

[0004] A heated digester works by heating the sample and a suitable digesting or dissolving agent to digest and dissolve it. The sample and solvent are placed in the reaction vessel within the heated digester and heated to a specific temperature. The high temperature and chemical reaction convert the organic and inorganic substances in the sample into soluble or extractable forms. Heated digesters typically have temperature control functions, allowing the heating temperature and time to be set and controlled as needed. Ultimately, the target components in the solution can be used for further analysis or measurement.

[0005] After heating, the digester expands and contracts due to heat, and the internal digestion vessel cannot be removed in time. It takes a long time for it to cool down naturally. Prolonged heating will cause the polytetrafluoroethylene digestion vessel to soften, affecting its service life.

[0006] Therefore, it is necessary to propose an intelligent constant-temperature heating digester to address the aforementioned technical problems. Utility Model Content

[0007] The purpose of this invention is to provide an intelligent constant temperature heating digester to solve the problem mentioned in the background art that after heating, the internal digestion vessel cannot be removed in time due to thermal expansion and contraction, and the time required for natural cooling is too long. Prolonged heating will cause the polytetrafluoroethylene digestion vessel to soften, affecting its service life.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an intelligent constant-temperature heating digester, comprising: a chassis, a heating plate, a heat insulation plate, a microwave digestion vessel, a cooling adjustment mechanism, a control panel, an electric telescopic rod switch, and a power switch.

The cooling adjustment mechanism is disposed inside the chassis, and includes an electric telescopic rod fixed inside the circular slot of the chassis and a groove cover disposed inside the microwave digestion vessel. The microwave digestion vessel is located on the output end of the electric telescopic rod. The grooved cover extends to halfway into the microwave digestion vessel. The grooved cover has a depth of 8-15cm, a diameter of 3.0-3.6cm, and a bottom thickness of 0.2-1cm. The base of the grooved cover has one or two small holes with a diameter of 1-5mm. The cooling adjustment mechanism also includes a first rod welded to the top of the chassis, a storage compartment slidably connected to the first rod, and a funnel welded to the bottom of the storage compartment. The funnel is inserted into the grooved cover. The control panel is located on the outer wall of the chassis. The control panel includes a real-time temperature display screen on the front of the chassis, a set temperature display screen on one side of the real-time temperature display screen, and a temperature-time setting device on one side of the set temperature display screen. The electric telescopic rod switch is located on one side of the outer wall of the chassis and is connected to the electric telescopic rod via a cable. The power switch is located on the outer wall of the chassis and is located on one side of the electric telescopic rod switch.

[0009] By adopting the above technical solution, multiple microwave digestion vessels can be cooled down quickly and then rapidly pushed out.

After preheating, ice is provided through a storage chamber and transported to the inside of the grooved cover through a funnel, preventing the ice from leaking to the outside when it is injected into the grooved cover. Thus, the sample temperature is cooled to room temperature as quickly as possible by storing ice in the grooved cover. The microwave digestion vessel is quickly pushed out by an electric telescopic rod, thereby preventing the microwave digestion vessel from softening due to prolonged heating.

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0034] The following is combined with Figure 1-8The embodiments of this utility model will be described in further detail.

[0035] This embodiment provides a technical solution: an intelligent constant temperature heating digester, including: a chassis 1, a heating plate 2, a heat insulation plate 3, a microwave digestion vessel 4, and a cooling adjustment mechanism 5;

[0036] The chassis 1 has a rectangular recess, which provides space for the internal structure. Multiple circular grooves are formed at the bottom of the rectangular recess to secure the internal structure. A power socket and a fuse are located at the rear of the chassis 1. The power socket can be a 146 type (86×146 mm), capable of accommodating three or more standard five-hole sockets, suitable for applications requiring more power outlets. The fuse can be a surface mount fuse, miniature fuse, blade fuse, or tubular fuse. The power socket provides power to the internal structure of the chassis 1 after the equipment is powered on. The fuse installed in the chassis 1 will melt and cut off the current when the current abnormally rises to a certain level, thus protecting the electrical components. Heating plate 2 is installed inside a rectangular groove in the chassis 1. Heating plate 2 is fixedly connected to the inside of chassis 1 by bolts. The heating plate 2 has a groove corresponding to the circular groove in chassis 1, which can provide a place for the internal structure. Heat insulation plate 3 is installed inside the rectangular groove in chassis 1. Heat insulation plate 3 is fixedly connected to the inside of chassis 1 by bolts. Heat insulation plate 3 is positioned above heating plate 2 to prevent the heat generated by heating plate 2 from being lost from the inside of chassis 1. Microwave digestion vessel 4 is installed inside the groove of heating plate 2. Microwave digestion vessel 4 can hold samples. Cooling adjustment mechanism 5 is installed inside chassis 1. Cooling adjustment mechanism 5 can quickly cool microwave digestion vessel 4 and facilitate the quick removal of microwave digestion vessel 4 from the outside of chassis 1.

[0037] The cooling adjustment mechanism 5 includes an electric telescopic rod 501 fixed inside the circular groove of the chassis 1. The electric telescopic rod 501 is fixedly connected by bolts. A grooved cover 502 is set inside the microwave digestion vessel 4. The grooved cover 502 can store coolant. The grooved cover 502 has a depth of 8-15cm, a diameter of 3.0-3.6cm, and a bottom thickness of 0.2-1cm. The base of the grooved cover 502 has two small holes with a diameter of 1-5mm. Due to its metal material, it has good heat conduction function. Ice cubes can be added to the grooved cover 502 after heating. The two small holes with a diameter of 1-5mm can release pressure during heating. The microwave digestion vessel 4 is set on the output end of the electric telescopic rod 501. The electric telescopic rod 501 can squeeze and push, thereby enabling the microwave digestion vessel 4 on the upper output end to move.

[0038] A first rod 503 is welded around the top of the chassis 1. The first rod 503 provides structural stability for vertical movement. A storage compartment 507 is slidably connected to the first rod 503. The bottom of the storage compartment 507 has multiple sets of holes. A funnel 508 is welded to the bottom of the storage compartment 507. The funnel 508 is welded to the inner wall of the holes in the storage compartment 507, thereby achieving an effective connection. The funnel 508 is inserted into the groove cover 502. The funnel 508 can transport the coolant in the storage compartment 507 to the inside of the groove cover 502.

[0039] The control panel 6 is mounted on the outer wall of the chassis 1. The control panel 6 can control the operation of the equipment inside the chassis 1. The control panel 6 includes a real-time temperature display screen 601 mounted on the front of the chassis 1. The real-time temperature display screen 601 can be an SK-DP-702B intelligent temperature display, which has an intelligent temperature and humidity display screen and can display the real-time temperature and the experimental set temperature. It is suitable for industrial and household environments. A set temperature display screen 602 is mounted on one side of the real-time temperature display screen 601. The set temperature display screen 602 can be an XMT-121-Chint temperature controller, which has functions such as temperature controller, digital display intelligent temperature control switch and adjustable heating temperature of 30-210℃. A temperature time setter 603 is mounted on one side of the set temperature display screen 602. The temperature time setter 603 can be a PRAD-D2000 programmable thermostat, which is suitable for various thermostat equipment and has multi-segment programmable control function.

[0040] The electric telescopic pole switch 7 is located on one side of the outer wall of the chassis 1. The model of the electric telescopic pole switch 7 can be NKLA22. It is a 24V electric telescopic pole with a stroke of 550MM, a load capacity of 750N, a speed of 10mm / s, and is equipped with a waterproof cover. The electric telescopic pole 501 is connected to the electric telescopic pole switch 7 through a cable, so that the electric telescopic pole 501 is activated or deactivated by the electric telescopic pole switch 7.

[0041] The power switch 8 is installed on the outer wall of the chassis 1. The model of the power switch 8 can be DZ47-63 / C63 or C40, which is suitable for home and light industrial environments. The DZ47 series is a plastic-cased snap-on switch. The power switch 8 can indicate whether the internal structure of the chassis 1 is operating after being powered on.

[0042] The chassis 1 is powered via a power socket. Power is then switched on (power switch 8) to confirm power-on. The microwave digestion vessel 4 is placed inside the heating plate 2 of the chassis 1. The temperature is adjusted via a temperature display screen 602, and the internal temperature of the chassis 1 can be observed via a real-time temperature display screen 601. The temperature-time setting device 603 adjusts the heating time inside the chassis 1 to digest and dissolve the sample. After processing the sample inside the microwave digestion vessel 4, coolant is transferred to the storage chamber 507. The liquid is conveyed through the funnel 508 at the bottom to the grooved cover 502 inside the microwave digestion vessel 4. At this time, the grooved cover 502 absorbs heat through its own metal material and dissipates heat through the internal coolant. When it is necessary to remove the microwave digestion vessel 4, the electric telescopic rod 501 at the bottom of the microwave digestion vessel 4 is activated by the electric telescopic rod switch 7. The electric telescopic rod 501 will push the microwave digestion vessel 4, so that the microwave digestion vessel 4 moves out of the interior of the heating plate 2 and the heat insulation plate 3. At this time, during the movement of the microwave digestion vessel 4, the storage compartment 507 placed above will be moved simultaneously by the first rod 503.

[0043] This embodiment provides a technical solution: an intelligent constant temperature heating digester, including: a connecting shaft 504, a second rod 505, a protrusion 506, a plug-in block 509, and a locking block 510;

[0044] A connecting shaft 504 is welded to one side of the center of the first rod 503. The connecting shaft 504 is not located at the center of the first rod 503, so that the structure on the connecting shaft 504 will be offset from the interior of the first rod 503 when rotating. A second rod 505 is welded to the top of the connecting shaft 504. The second rod 505 can cooperate with the first rod 503, so that the storage compartment 507 on the rod can move stably. The second rod 505 has an integrally formed limit plate, which can prevent the storage compartment 507 on the rod from falling off during the movement. A protrusion 506 is rotatably connected to the connecting shaft 504. The protrusion 506 can be displaced outside the first rod 503 and the second rod 505 during rotation, so as to position the structure on the second rod 505. The diameter of the protrusion 506 is the same as that of the first rod 503.

[0045] A plug-in block 509, made of metal, is welded to the bottom of the storage compartment 507. A locking block 510 is integrally formed above the microwave digestion vessel 4, and the plug-in block 509 is locked inside the locking block 510. After the locking block 510 and the plug-in block 509 are connected, the storage compartment 507 and the microwave digestion vessel 4 can be connected.

[0046] The storage compartment 507 is connected to the locking block 510 on the microwave digestion vessel 4 via the bottom plug-in block 509. This allows the storage compartment 507 to move synchronously and stably during the movement of the microwave digestion vessel 4. After the storage compartment 507 moves to the designated position, the protrusion 506 on the rotating connecting shaft 504 is rotated outward from the first rod 503 and the second rod 505. This allows the storage compartment 507 located on the second rod 505 to be positioned by the protrusion 506 below, thus enabling the rapid disassembly of the structure below the storage compartment 507.

[0047] The working principle is as follows:

[0048] The chassis 1 is powered by a power socket. Then, the power switch 8 is turned on to confirm whether the work is started. The microwave digestion vessel 4 is placed inside the heating plate 2 of the chassis 1. The temperature is adjusted by the temperature display screen 602. At this time, the temperature inside the chassis 1 can be observed by the real-time temperature display screen 601. The temperature rise time inside the chassis 1 is adjusted by the temperature time setter 603 to digest and dissolve the sample. After the sample inside the microwave digestion vessel 4 is processed.

[0049] By delivering coolant into the storage chamber 507, the storage chamber 507 delivers the coolant through the funnel 508 at the bottom into the grooved cover 502 inside the microwave digestion vessel 4. At this time, the grooved cover 502 absorbs heat through its own metal material and dissipates heat through the coolant inside.

[0050] When the microwave digestion vessel 4 needs to be removed, the electric telescopic rod 501 at the bottom of the microwave digestion vessel 4 is activated. The electric telescopic rod 501 will push the microwave digestion vessel 4, causing it to move out of the heating plate 2 and the heat insulation plate 3. During the movement of the microwave digestion vessel 4, the storage compartment 507 placed above will be moved synchronously via the first rod 503. The storage compartment 507 is connected to the locking block 510 on the microwave digestion vessel 4 via the bottom plug-in block 509, thus synchronously and stably moving the storage compartment 507 during the movement of the microwave digestion vessel 4. After the storage compartment 507 moves to the designated position, the protrusion 506 on the connecting shaft 504 is rotated. During the rotation, the protrusion 506 on the connecting shaft 504, which is offset from the center, can rotate out to the outside of the first rod 503 and the second rod 505. This allows the storage compartment 507 located on the second rod 505 to be positioned by the protrusion 506 below, thereby quickly disassembling the structure below the storage compartment 507.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
