Abstract
Description
Technical Field
[0001] This utility model relates to the field of microwave digestion technology, and in particular to a water receiving tank device for a microwave digestion instrument. Background Technology
[0002] Microwave digesters are widely used in chemical analysis sample pretreatment due to their high efficiency and rapid digestion capabilities. However, after high-temperature and high-pressure digestion and subsequent cooling and depressurization, a common problem often arises: a large amount of steam remains inside the equipment after digestion. This steam rapidly condenses upon contact with the cooler top cover and inner walls, forming condensate. When the operator opens the cover for the next step, the upright top cover causes the condensate to flow downwards due to gravity. Without effective water collection measures, the condensate will inevitably drip onto the instrument surface or seep into the instrument through gaps.
[0003] This not only leads to corrosion of the instrument casing, affecting the appearance and lifespan of the equipment, but more importantly, once condensate enters critical areas inside the instrument, it may cause serious malfunctions such as short circuits in electronic components, thereby affecting the accuracy of experimental results and the safety of the equipment.
[0004] Therefore, how to provide a water collection tank device for a microwave digester that can effectively collect condensate when the top cover is open is a technical problem that needs to be solved by those skilled in the art. Utility Model Content
[0005] The purpose of this invention is to provide a water collection tank device for a microwave digester, which solves the technical problem that condensate cannot be collected when the cover of the existing microwave digester is opened.
[0006] To achieve the above objectives, this utility model provides a water receiving tank device for a microwave digester. The microwave digester includes a main body and a cover for sealing the opening of the main body. A connecting seat is provided on the outer side of the main body, and a connecting rod rotatably connected to the connecting seat is provided on the cover. The water receiving tank device includes:
[0007] The upper water receiving tank includes a vertical plate and a horizontal plate disposed on one side of the top of the vertical plate. The bottom of the side of the vertical plate away from the horizontal plate is provided with a flow groove. The horizontal plate is provided with a water receiving cavity. The side of the water receiving cavity near the vertical plate is provided with an opening.
[0008] The lower water receiving tank is symmetrically and detachably connected to the bottom sides of the upper water receiving tank. The receiving cavities of the two lower water receiving tanks are located below the openings at both ends of the flow channel. The connecting seat has an installation notch on the side near the main body. The vertical plate can be inserted into the installation notch. The horizontal plate is located at the upper end of the connecting seat. The two lower water receiving tanks are located on both sides of the connecting seat.
[0009] The height of the anti-overflow flange of the water receiving cavity is 3-5mm.
[0010] The upper water receiving tank and the lower water receiving tank are connected by a snap-fit mechanism. The snap-fit mechanism is set on the lower water receiving tank, and the bottom sides of the upper water receiving tank are provided with slots that cooperate with the snap-fit mechanism.
[0011] Preferably, the upper water receiving tank and the lower water receiving tank are magnetically connected.
[0012] Preferably, the bottom of the upper water receiving tank is provided with an arc-shaped groove that fits into the installation notch.
[0013] Preferably, both the upper water receiving tank and the lower water receiving tank are polytetrafluoroethylene (PTFE) tanks.
[0014] Preferably, the depth of the flow channel is 5-8 mm.
[0015] Preferably, the bottom of the lower water receiving tank is provided with a guide hole, which is used to connect a guide pipe, and the guide pipe is connected to the collector.
[0016] Compared to the aforementioned background technology, this utility model provides a water receiving tank device for a microwave digester. After the microwave digester completes digestion and cools down, the cover is opened, and the condensate generated on the inner wall of the cover flows down along the cover and drips into the water receiving cavity of the upper water receiving tank. The condensate in the water receiving cavity flows into the flow channel through the opening and is further distributed to the receiving cavities of the lower water receiving tanks on both sides. The receiving cavities of the lower water receiving tanks are checked regularly. When the condensate accumulates to a certain amount, the lower water receiving tanks are disassembled for cleaning. After cleaning, they can be reinstalled for continued use.
[0017] In summary, the combination of the upper and lower water collection tanks can collect condensate generated when the microwave digester is opened, preventing condensate from dripping onto the instrument casing and avoiding malfunctions such as corrosion and short circuits caused by condensate. The lower and upper water collection tanks are detachably connected, allowing the lower tank to be disassembled for cleaning, which is simple and convenient, reducing maintenance costs. The entire water collection device has a simple structure, low manufacturing cost, and is easy to promote and apply on a large scale. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Example 1:
[0028] See Figures 1-4 This application provides a water receiving tank device for a microwave digester. The microwave digester includes a body 1 and a cover 2 for sealing the opening of the body 1. A connecting seat 3 is provided on the outside of the body 1, and a connecting rod 4 is provided on the cover 2 for rotatable connection with the connecting seat 3. The water receiving tank device includes: an upper water receiving tank 5, including a vertical plate and a horizontal plate provided on one side of the top of the vertical plate. A flow channel 6 is provided at the bottom of the side of the vertical plate away from the horizontal plate. A water receiving cavity 7 is provided on the horizontal plate, and the side of the water receiving cavity 7 near the vertical plate is provided with an opening; and lower water receiving tanks 8, symmetrically and detachably connected to the bottom sides of the upper water receiving tank 5. The receiving cavities 9 of the two lower water receiving tanks 8 are located below the openings at both ends of the flow channel 6. An installation notch 10 is provided on the side of the connecting seat 3 near the body 1. The vertical plate can be inserted into the installation notch 10. The horizontal plate is located at the upper end of the connecting seat 3, and the two lower water receiving tanks 8 are located on both sides of the connecting seat 3.
[0029] In other words, the vertical plate has a certain height and thickness, and its size matches the installation notch 10 of the connecting seat 3, so that it can be inserted into it.
[0030] A horizontal plate is set on one side of the top of the vertical plate and is vertically connected to the vertical plate. A water receiving cavity 7 is provided on the horizontal plate. The side of the water receiving cavity 7 near the vertical plate is set as an opening so as to receive the condensate flowing down from the cover 2. A flow channel 6 is opened at the bottom of the side of the vertical plate away from the horizontal plate. It is a long strip-shaped slot with its two ends corresponding to the receiving cavity 9 of the lower water receiving tank 8, and is used to guide the condensate in the water receiving cavity 7 to the lower water receiving tank 8.
[0031] The lower water receiving tank 8 is symmetrically and detachably connected to the bottom sides of the upper water receiving tank 5. Each lower water receiving tank 8 is provided with a receiving cavity 9. The size and position of the receiving cavity 9 correspond to the bottom of the two ends of the flow channel 6, ensuring that the condensate flowing down from the flow channel 6 can be accurately received.
[0032] Installation method: Align the vertical plate of the upper water receiving tank 5 with the installation notch 10 of the microwave digester connector 3, and slowly insert it so that the vertical plate is completely embedded in the installation notch 10. At the same time, ensure that the horizontal plate is located at the upper end of the connector 3 and the opening direction of the water receiving cavity 7 is correct. Then install the lower water receiving tank 8 on the bottom sides of the upper water receiving tank 5 respectively, so that its receiving cavity 9 is located directly below the openings at both ends of the flow channel 6.
[0033] Instructions for use: After the microwave digester has completed digestion and cooled down, open the cover 2. The condensate generated on the inner wall of the cover 2 will flow down along the cover 2 and drip into the water receiving chamber 7 of the upper water receiving tank 5. The condensate in the water receiving chamber 7 will flow into the flow channel 6 through the opening, and then be further distributed to the receiving chambers 9 of the lower water receiving tanks 8 on both sides. Regularly check the receiving chambers 9 of the lower water receiving tanks 8. When the condensate accumulates to a certain amount, disassemble the lower water receiving tanks 8 for cleaning. After cleaning, reinstall them and continue to use.
[0034] Beneficial effects: The combination of the upper water receiving tank 5 and the lower water receiving tank 8 can collect the condensate generated when the microwave digester is opened, preventing the condensate from dripping onto the instrument shell and avoiding instrument failures such as corrosion and short circuits caused by condensate. The lower water receiving tank 8 is detachably connected to the upper water receiving tank 5, and the lower water receiving tank 8 can be disassembled for cleaning. The cleaning process is simple and convenient, reducing maintenance costs. The entire water receiving tank device has a simple structure, low manufacturing cost, and high cost performance, making it easy to promote and apply on a large scale.
[0035] Based on the above embodiments, the height of the anti-overflow flange of the water receiving cavity 7 is 3-5mm, preferably 5mm, to prevent condensate from overflowing.
[0036] Based on the above embodiments, the upper water receiving tank 5 and the lower water receiving tank 8 are connected by a snap-fit, with the snap-fit set on the lower water receiving tank 8, and the bottom sides of the upper water receiving tank 5 are provided with slots that cooperate with the snap-fit.
[0037] In other words, the upper water receiving tank 5 and the lower water receiving tank 8 are connected by a snap-fit method, which simplifies the installation process. Compared with traditional bolt connections, snap-fit connections do not require additional tools. Operators only need to align the snaps on the lower water receiving tank 8 with the slots on both sides of the bottom of the upper water receiving tank 5 and press down slightly to achieve a quick connection, greatly saving installation time and improving work efficiency.
[0038] For disassembly, when the lower water tank 8 needs to be cleaned or replaced, operators do not need complicated procedures. They can simply use their fingers to gently squeeze or pry the clips to disengage them from the slots, and the lower water tank 8 can be easily removed from the upper water tank 5. The clip connection method makes daily maintenance of the water tank device easy, reducing maintenance costs and difficulty.
[0039] Based on the above embodiments, the bottom of the upper water receiving tank 5 is provided with an arc-shaped groove that fits with the installation notch 10. That is, the arc-shaped groove is adapted to the inner contour of the installation notch 10 of the microwave digester connector 3. The radius of the arc-shaped groove is determined according to the size of the installation notch 10 to ensure that the two fit tightly. The depth of the arc-shaped groove is moderate to ensure the stability of the upper water receiving tank 5 installation.
[0040] Based on the above embodiments, both the upper water receiving tank 5 and the lower water receiving tank 8 are made of polytetrafluoroethylene (PTFE). PTFE has excellent chemical stability and can withstand the corrosion of various strong acids, strong alkalis, and organic solvents used in microwave digestion. In microwave digestion experiments, commonly used highly corrosive reagents such as nitric acid, hydrochloric acid, and hydrofluoric acid can cause severe corrosion to ordinary materials. However, water receiving tanks made of PTFE can be used for a long time in such environments without corrosion, extending the service life of the water receiving tanks and reducing the frequency and cost of replacing them.
[0041] Polytetrafluoroethylene (PTFE) also has excellent high-temperature resistance. Microwave digestion instruments generate high temperatures during operation, and PTFE can withstand these high temperatures without deformation or damage, ensuring that the water collection tank effectively collects condensate in high-temperature environments.
[0042] Based on the above embodiments, the depth of the flow groove 6 is 5-8mm.
[0043] Based on the above embodiments, the bottom of the lower water receiving tank 8 is provided with a guide hole for connecting a guide pipe, which is connected to the collector. In other words, by setting a guide hole at the bottom of the lower water receiving tank 8 and connecting the guide pipe to the collector, automatic collection and centralized treatment of condensate are achieved. This reduces the frequency of manual cleaning of the lower water receiving tank 8, improves work efficiency, and avoids the problem of condensate spillage during cleaning, maintaining a clean working environment. Simultaneously, collecting the condensate in the collector facilitates unified treatment of the condensate, such as neutralization and purification, meeting environmental protection requirements.
[0044] Example 2:
[0045] The difference between this embodiment and Embodiment 1 is that the upper water receiving tank 5 and the lower water receiving tank 8 are connected by bolts. Specifically, multiple evenly distributed connecting lugs are provided on the top edge of the lower water receiving tank 8, and each connecting lug has a through hole drilled to fit the bolt. Similarly, corresponding threaded holes are also provided at the bottom of the upper water receiving tank 5. The bolt specifications are selected according to the size of the water receiving tank and the actual load-bearing requirements. M4-M6 stainless steel bolts can be used to ensure the stability of the connection.
[0046] Example 3:
[0047] The difference between this embodiment and Embodiment 1 is that the upper water receiving tank 5 and the lower water receiving tank 8 are connected by magnetic attraction. Specifically, multiple permanent magnets are evenly embedded in the top edge of the lower water receiving tank 8. Simultaneously, permanent magnets matching the magnets in the lower water receiving tank 8 are installed at corresponding positions on the bottom of the upper water receiving tank 5, with opposite polarities to achieve mutual attraction. High-performance neodymium iron boron permanent magnets are selected, characterized by high remanence, high coercivity, and high energy product, providing strong attraction and ensuring a tight connection between the upper and lower water receiving tanks 5 and 8. Furthermore, the surface of the neodymium iron boron permanent magnets undergoes special anti-corrosion treatment, such as zinc plating or nickel plating, to prevent rusting upon contact with condensate or corrosive substances generated during the digestion process, thus extending the magnet's service life.
[0048] Compared to the snap-fit connection in Embodiment 1 and the bolt connection in Embodiment 2, the magnetic connection is the simplest to install. The operator only needs to bring the lower water tank 8 close to the upper water tank 5; under the attraction of the magnet, the two will automatically align and fit tightly together, eliminating the need for tedious alignment and tightening operations and greatly saving installation time.
[0049] Easy disassembly: When it is necessary to clean or replace the lower water tank 8, the operator only needs to use a little force to pull the lower water tank 8 off the upper water tank 5. No tools are needed, making the operation very convenient.
[0050] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0051] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
