[0036] Figure 1 This diagram shows the overall structure of the evaporator platform protection device provided in one embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of the cooling pipes arranged inside the rear baffle according to an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of the present invention according to an embodiment, showing the fan disposed on the outside of the rear baffle.

[0037] like Figures 1 to 3As shown, the evaporator protection device includes an annular cover 1 for covering the evaporator. This type of evaporator currently lacks any protective measures and is directly exposed to the laboratory environment for heating. Furthermore, the evaporator is a structure known to those skilled in the art; therefore, it will not be described in detail further. In this application, the evaporator is preferably used to process solutions from a VPD machine, for evaporating LPD and VPD solutions, and then for ICP-MS testing.

[0038] Furthermore, the evaporation platform protective device also includes: a transparent observation window 2, located on the top opening of the cover 1; a loading / unloading door 3, located on the front side of the cover 1; and a heat dissipation system 4 (see...). Figure 2 and Figure 3 It is installed on the rear side of the cover 1. For simplicity, the evaporation platform protective device will be referred to as the protective device in the following text.

[0039] Understandably, when using the protective device, the cover 1 can block the liquid (mainly acidic solution) splashed out due to overpressure explosion during the heating process of the evaporation platform, thereby preventing the liquid from splashing onto personnel and equipment near the evaporation platform. This ensures the personal safety of operators and personnel using other items near the evaporation platform, and also protects surrounding equipment and facilities from damage. The transparent observation window 2 is used to observe the internal state of the evaporation platform during the heating process. It can be made of any suitable transparent material, preferably a high-temperature resistant and non-toxic material, such as plastic or glass. The access door 3 allows for the access of heating components such as liquid pipes and containers when using the evaporation platform. In addition, the heat dissipation system 4 is used for heat dissipation and cooling to prevent the internal temperature of the protective device from becoming too high, thereby preventing the protective device from overheating and affecting its safety. The heat dissipation system 4 can achieve the purpose of heat dissipation and cooling through various measures.

[0040] One method of using the protective device is as follows: First, cover the evaporation platform with the cover 1; then, place the transparent observation window 2 on top of the cover 1; then, open the loading and unloading door 3 and put in the heating spare parts; then, close the loading and unloading door 3, start the evaporation platform, and observe the internal condition of the evaporation platform through the transparent observation window 2 during the evaporation process. If there is any abnormality, the evaporation platform can be stopped in time; after the evaporation is completed, open the loading and unloading door 3 to take out the heating spare parts.

[0041] As those skilled in the art will understand, the cover 1 can be disassembled as a whole or in modules, and is especially convenient when disassembled in modules. It should also be noted that the transparent observation window 2 can be an integral part of the cover 1 or a separate unit.

[0042] like Figure 1As shown, in a preferred embodiment, the cover 1 includes multiple baffles 110, such as two, three, four, or more. In practice, the specific number of baffles 110 can be determined according to the shape of the evaporation table; or, in other words, the shape of the cover 1 is preferably adapted to the shape of the evaporation table. For example, evaporation tables currently used in laboratories are mostly cuboids or cubes, so the cover 1 preferably uses four baffles 110 to form a rectangle. Of course, this is not a limitation. Regardless of the number of baffles 110, they are arranged circumferentially around the evaporation table and are detachably connected in sequence to form a circumferentially closed cover 1. Therefore, adjacent baffles 110 are detachably connected; in use, the baffles 110 are assembled together; when not in use, each baffle 110 can be disassembled individually; this structure is simple and convenient to assemble, disassemble, and use.

[0043] In this embodiment, the four baffles 110 include a front baffle 11, a rear baffle 12, and two side baffles 13; the front baffle 11, the side baffles 13, and the rear baffle 12 are detachably connected in sequence; the loading and unloading door 3 is disposed on the front baffle 11; and the heat dissipation system 4 is disposed on the rear baffle 12.

[0044] The connection method between adjacent baffles 110 is not limited; adjacent baffles 110 can be directly connected or connected via additional connectors 14. For example, the side baffle 13 and the rear baffle 12 are connected via connectors 14, and / or the front baffle 11 and the side baffle 13 are connected via connectors 14. In this embodiment, connectors 14 are respectively provided at positions corresponding to the side baffle 13 on the front baffle 11 and the rear baffle 12, and the connectors 14 are detachably connected to the corresponding side baffle 13, which facilitates the assembly and disassembly of the baffles 110. There are multiple connection methods between adjacent baffles 110, and at least one can be selected for implementation.

[0045] For example, both the front baffle 11 and the rear baffle 12 can be connected to the connector 14 by means of screws, adhesive, or welding, or they can be integrally formed with the connector 14. In this embodiment, the connector 14 is fixedly connected to both the rear baffle 12 and the front baffle 11 by screws, and at the same time, the connector 14 is snap-fitted to the corresponding side baffle 13.

[0046] More detailed, such as Figure 2 and Figure 3 As shown, threaded holes 121 are provided on both the left and right edges of the rear baffle 12; at the same time, as Figures 7 to 9 As shown, the connector 14 is provided with a threaded hole 141; thus, after the threaded hole 121 on the rear baffle 12 is aligned with the threaded hole 141 on the connector 14, it is locked by screws. It is worth noting that there is no specific limitation on the specific number of the threaded holes 141 and 121, as long as the baffle 110 can be securely locked.

[0047] like Figure 1 As shown, a connecting member 14 is provided at the position of the front baffle 11 corresponding to the side baffle 13. Figures 7 to 9 As shown, the connector 14 is provided with a snap-fit ​​protrusion 142, which is used to engage with the snap-fit ​​groove 131 on one side of the side baffle 13 for fixation. Compared with other detachable fixing methods, snap-fit ​​fixing is simpler and more reliable, requires no additional tools or equipment, saves time and effort, improves work efficiency, does not require the use of glue or other chemical materials, is environmentally friendly, and also reduces assembly costs and the use of parts.

[0048] Next, refer to Figures 4 to 6 As shown, as an example, the front and rear ends of the side baffle 13 are respectively provided with snap-fit ​​grooves 131; thereby, the side baffle 13 is fixed by the snap-fit ​​groove 131 on one side cooperating with the snap-fit ​​protrusion 142 on one side of the connector 14.

[0049] Of course, the above-described snap-fit ​​and screw connections are for illustrative purposes only and do not constitute a limitation on the technical solution of this invention.

[0050] Furthermore, when setting the transparent observation window 2, as an example, a placement platform 132 is provided on the inner top side of the cover 1, and the transparent observation window 2 is placed directly flat on the placement platform 132. Specifically, see... Figure 4 and Figure 6 The inner side of the side baffle 13 is provided with a placement platform 132 near the top. The transparent observation window 2 can be placed flat on the placement platform 132 without any additional fixing.

[0051] refer to Figure 1 and Figure 5 As an example, the side of the cover 1 is provided with holes 133 for wires on the evaporation table to pass through, and the holes 133 are preferably located at the bottom of the cover 1. To avoid scratching the wires, the holes 133 are further designed to be open. Specifically, in this embodiment, at least one of the side baffles 13 has holes 133 at its bottom. The shape, size, and number of the holes 133 are not limited.

[0052] The retrieval door 3 can be a revolving door or a sliding door. For ease of use, the retrieval door 3 is equipped with a door handle 5. For example, in this embodiment, the retrieval door 3 is a double sliding door, with one door handle 5 on each sliding door.

[0053] The following is a further explanation of the heat dissipation system 4.

[0054] Figure 2 and Figure 3In the preferred embodiment described, the heat dissipation system 4 includes both cooling pipes 41 and a fan 42. However, in other cases, the heat dissipation system 4 may only include either cooling pipes 41 or a fan 42. In practice, considering the high heating temperature of the evaporation platform, both cooling pipes 41 and a fan 42 are provided simultaneously to achieve better cooling effects, which can better control the internal temperature of the protective device and ensure safe use.

[0055] Preferably, the cooling pipe 41 is located on the inner rear side of the cover 1, that is, on the inner side of the rear baffle 12, see details below. Figure 2 The cooling pipe 41 can be fixed to the inner wall of the body 1 by various means. In this embodiment, a plurality of pipe clamps 15 are provided on the inner wall of the annular body 1, or on the inner wall of the rear baffle 12, and the pipe clamps 15 fix the cooling pipe 41. The pipe clamps 15 are simple and reliable for fixing.

[0056] It should be noted that the cooling pipes 41 can be arranged in various ways; for example, the cooling pipes 41 can be connected in series, with water flowing through each pipe sequentially; multiple cooling pipes 41 can be arranged in parallel, with water entering each pipe simultaneously and then converging and flowing out; the cooling pipes 41 can be arranged in a serpentine or meandering manner, bending back and forth in a plane or three-dimensional space; the cooling pipes 41 can be arranged in a spiral shape; the cooling pipes 41 can be arranged in a grid pattern; and other arrangements of the cooling pipes 41 are also possible. In short, in practical applications, the arrangement of the cooling pipes 41 can be combined and adjusted according to specific circumstances to achieve the best cooling effect while minimizing costs. Furthermore, the cooling medium can be liquid or gas, with circulating cooling water being the most commonly used.

[0057] In this embodiment, the cooling pipe 41 is arranged in a serpentine manner. The cooling water pipe 41 has an inlet and an outlet. The cooling medium flows into the cooling pipe 41 from the inlet and finally flows out of the cooling pipe 41 from the outlet.

[0058] Preferably, the fan 42 is located on the rear outer side of the cover 1, specifically, on the outer side of the rear baffle 12, see details. Figure 3 The fan 42 can also be fixed to the outer wall of the rear baffle 12 by various means. Generally, the fan 42 is locked to the rear baffle 12 with screws.

[0059] As will be understood by those skilled in the art, the number of the fans 42 is one or more, and the plurality may be two, three or more. Optionally, the plurality of the fans 42 are arranged laterally.

[0060] Preferably, a wire groove 122 is provided on the rear outer wall of the cover 1, that is, on the outer wall of the rear baffle 12, for accommodating the fan wires. For example, optionally, the wire groove 122 includes a long horizontal wire groove 1221 and several short vertical wire grooves 1222, each vertical wire groove 1222 extending to a corresponding fan 42. However, it should be understood that the shape and position of the wire groove 122 can be adjusted according to the position and number of fans 42.

[0061] While the present invention has been disclosed above, it is not limited thereto. Those skilled in the art can make various modifications and variations to the present invention without departing from its spirit and scope. Therefore, if such modifications and variations fall within the scope of this specification and its equivalents, the present invention also intends to include such modifications and variations.
