Description

Technical Field

[0001] This utility model relates to the field of chemical analysis instrument technology, specifically to a corrosion-resistant structure for a digester. Background Technology

[0002] Online analyzers are widely used in environmental monitoring. As an indispensable part of online analyzers, digestion devices are often used to digest corrosive liquids under high temperature and high pressure conditions.

[0003] like Figure 1 As shown, the digester in the prior art includes a dosing platform, a heating platform, and a support frame. The dosing platform is located above the heating platform, and the support frame is supported between the dosing platform and the heating platform. The dosing platform has multiple round holes for placing dosing containers. A conical flask is placed on the heating platform directly below the round holes. The conical flask contains a water sample. The dosing container is used to hold the reagent, and the reagent in the dosing container is introduced into the conical flask through a tube on the dosing container.

[0004] In actual operation, the test personnel need to pour the reagent into the dosing vessel on the top of the digester. However, the reagent is usually a corrosive solvent, such as sulfuric acid. It is easy for the reagent to spill onto the top of the digester's dosing platform when pouring, which can cause corrosion on the top of the digester and affect its service life. Utility Model Content

[0005] This invention provides a corrosion-resistant structure for a digester, which aims to prevent corrosion of the top of the digester and extend its service life.

[0006] This utility model is achieved through the following technical solution: a corrosion-resistant structure for a digester, comprising a digester body, the digester body including a heating platform, a dosing platform and a support frame, the dosing platform having multiple placement holes, the dosing platform being located above the heating platform, the support frame being connected between the dosing platform and the heating platform, the top of the dosing platform being covered with a protective pad, the protective pad having multiple communicating holes respectively aligned with and communicating with the multiple placement holes.

[0007] Compared with existing technologies, this solution has the following advantages and beneficial effects:

[0008] In this solution, a protective pad is laid on top of the dosing platform. The protective pad can protect and shield the top of the dosing platform, preventing spilled liquid from contaminating and corroding the dosing platform when the agent is introduced into the dosing vessel placed in the storage hole of the dosing platform, thereby extending the service life of the entire digester.

[0009] Furthermore, the top of the dosing platform has two beveled sides forming two slopes, and the shape of the protective pad matches the shape of the top of the dosing platform.

[0010] In this design, the top of the dosing platform is beveled on both sides to form two inclined surfaces, and the shape of the protective pad matches the shape of the top of the dosing platform. This ensures that when the protective pad is laid on the dosing platform, it does not alter the shape of the platform's top, thus allowing the addition of the protective pad to maintain the original experimental operation. Furthermore, the combination of the inclined surface of the dosing platform top and the protective pad enhances the control over the placement of the protective pad, making it more stable and less prone to slipping.

[0011] Furthermore, the protective pad includes a flat plate and two inclined plates, the connecting hole is formed on the flat plate, the two inclined plates are respectively connected to the two sides of the flat plate, and the inclined plates match the inclined surface of the dosing platform.

[0012] Beneficial effects: The protective pad in this design can be composed of a flat plate and two inclined plates, forming a structure that matches the shape of the top of the dosing station.

[0013] Furthermore, the protective pad is detachably connected to the dosing station.

[0014] This design makes it easy to replace and install the protective pad.

[0015] Furthermore, the top two sides of the dosing station are provided with limiting grooves, and the bottom two sides of the protective pad are connected with limiting blocks. The limiting blocks on the bottom two sides of the protective pad can be inserted into the limiting grooves on the top two sides of the dosing station, respectively.

[0016] In this design, the limiting grooves on both sides of the top of the dosing station fit into the limiting blocks on both sides of the bottom of the protective pad, which can restrict the installation position of the protective pad and prevent it from sliding and falling off without the application of external force.

[0017] Furthermore, the protective pad is connected to a plurality of extension tubes that are respectively connected to a plurality of the communication holes, and the bottom of the extension tubes extends to the bottom of the communication holes and can be inserted into the storage hole of the dosing station.

[0018] The extension tube in this design allows it to be inserted into the storage hole of the dosing platform when installing the protective pad. This not only positions the protective pad to ensure its accuracy but also further restricts its movement, preventing it from sliding or falling off, thus improving the stability of the protective pad installation.

[0019] Furthermore, the upper part of the extension tube is located inside the connecting hole and is coaxially and detachably connected to the connecting hole.

[0020] In this design, the upper part of the extension tube is located inside the connecting hole and is detachably connected to the connecting hole. This facilitates the placement and removal of the extension tube, and allows for the replacement of one or more extension tubes depending on the corrosion situation. This eliminates the need to remove the entire protective pad for replacement, thus saving costs.

[0021] Furthermore, the top of the extension tube is provided with a flared end, which can abut against the top side of the connecting hole of the protective pad.

[0022] The flared end in this design allows for a detachable connection between the extension tube and the connecting hole, while also guiding the inserted dosing vessel to facilitate its rapid placement.

[0023] Furthermore, the two ends of the protective pad extend out from the top sides of the dosing platform, respectively.

[0024] With this design, since the two ends of the protective pad extend beyond the top of the dosing station, it is easy to grasp the edges of the protective pad with your hands and apply force to remove it smoothly when taking it out.

[0025] Furthermore, the protective pad is an acid and alkali resistant protective pad.

[0026] The protective pads in this solution are resistant to acid and alkali corrosion and have a long service life, thus providing effective protection for the dosing station. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0040] Example 1

[0041] like Figure 2 As shown, this embodiment 1 provides a corrosion-resistant structure for a digester, including a digester body. The digester body includes a heating platform 1, a dosing platform 2, and a support frame 3. The dosing platform 2 has multiple placement holes 4. The dosing platform 2 is located above the heating platform 1. The support frame 3 is welded or screwed between the dosing platform 2 and the heating platform 1.

[0042] Combination Figure 3 and Figure 4 As shown, a protective pad 5 is laid on the top of the dosing station 2, and multiple connecting holes 503 are opened on the protective pad 5, which are aligned with and connected to multiple storage holes 4.

[0043] In this embodiment, the top of the dosing platform 2 is beveled on both sides to form two inclined surfaces, and the shape of the protective pad 5 matches the shape of the top of the dosing platform 2. Specifically: Figure 3As shown, the protective pad 5 includes a flat plate 501 and two inclined plates 502. A connecting hole 503 is formed on the flat plate 501. The two inclined plates 502 are respectively connected to the two sides of the flat plate 501. In this embodiment, the two inclined plates 502 are integrally formed with the flat plate 501. The inclined plates 502 match the inclined surface on the dosing platform 2, that is, the inclined plates 502 and the flat plate 501 can fit against the top of the dosing platform 2 to complete the laying.

[0044] In this embodiment, the protective pad 5 is an acid and alkali resistant protective pad, that is, a protective pad made of acid and alkali resistant materials in the prior art.

[0045] Combination Figure 4 As shown, in this embodiment, the two ends of the protective pad 5 extend out of the top two sides of the dosing platform 2, so that the edges of the protective pad 5 are suspended, making it easier to operate the hand when taking the protective pad 5 out.

[0046] The specific implementation process is as follows: The protective pad 5 is laid on the top of the dosing platform 2 and fits against the top plane and the two side slopes of the dosing platform 2. The multiple connecting holes 503 on the protective pad 5 are aligned with the storage holes 4 on the dosing platform 2. The dosing vessel is then inserted into the connecting holes 503 on the protective pad 5 and into the storage holes 4 on the dosing platform 2 to complete the installation. When adding the agent into the dosing vessel, if the agent is accidentally spilled, the protective pad 5 can play a protective role, preventing the spilled agent from directly contacting the top of the dosing platform 2 and corroding the dosing platform 2.

[0047] Example 2

[0048] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the protective pad 5 and the dosing platform 2 are detachably connected. Specifically, the dosing platform 2 has limiting grooves 201 on both sides of its top. The limiting grooves 201 can be a structure with through grooves at both ends or a structure with closed grooves at both ends. Figure 6 As shown, the bottom sides of the protective pad 5 are connected to limit blocks 505. In this embodiment, the limit blocks 505 are integrally formed with the bottom of the protective pad 5. The limit blocks 505 on both sides of the bottom of the protective pad 5 can be inserted into the limit grooves 201 on both sides of the top of the dosing platform 2, thereby realizing the detachable connection between the protective pad 5 and the dosing platform 2.

[0049] Combination Figure 7 As shown, when the limiting groove 201 and the limiting block 505 cooperate with each other, they can position the installation of the protective pad 5, making it less likely for the protective pad 5 to slip off, and enabling the connecting hole 503 on the protective pad 5 to quickly align with the placement hole 4 on the dosing platform 2.

[0050] In this embodiment, the protective pad 5 is connected to a plurality of extension tubes 504 that are respectively connected to a plurality of connecting holes 503. The bottom of the extension tube 504 extends to the bottom of the connecting hole 503 and can be inserted into the placement hole 4 of the dosing platform 2. In this embodiment, the extension tube 504 and the protective pad 5 are integrally formed. The extension tube 504 is designed so that when the protective pad 5 is placed on the dosing platform 2, the extended part of the extension tube 504 can be inserted into the corresponding connecting hole 503. This can further restrict the installation position of the protective pad 5 and make the installation of the protective pad 5 more stable.

[0051] Example 3

[0052] Combination Figure 8 As shown, the difference between this embodiment and embodiment 2 is that in this embodiment, the upper part of the extension tube 504 is located inside the connecting hole 503 and is coaxially and detachably connected to the connecting hole 503. Specifically, there is a clearance fit between the extension tube 504 and the connecting hole 503. In this embodiment, the top of the extension tube 504 is provided with a flared end 506. The flared end 506 can abut against the top side of the connecting hole 503 of the protective pad 5. That is, the flared end 506 is located outside the connecting hole 503, and the outer diameter of the flared end 506 is larger than the outer diameter of the connecting hole 503. Thus, when the extension tube 504 is inserted into the connecting hole 503, the flared end 506 will abut against the top side of the connecting hole 503. Under the action of its flared end 506, the extension tube 504 will be restricted on the protective pad 5 and will not slide downward, thereby completing the detachable installation of the extension tube 504.

[0053] Due to the uncertainty of the experimenter's operation during use, sometimes errors may occur when adding chemicals to the multiple dosing vessels placed on the dosing platform 2, causing the chemicals to spill from the vessel walls. Over time, this may lead to corrosion of the extension tube 504. Since the location of the spilled chemicals is uncertain, some areas will be severely corroded, some will be slightly corroded, and some will not be corroded at all. Therefore, in practice, when the protective pad 5 is not widely contaminated by chemicals, one or several extension tubes 504 can be replaced according to the actual situation, instead of removing and replacing the entire protective pad 5, thus saving costs and reducing the difficulty of replacement.

[0054] Example 4

[0055] like Figure 9 As shown, the difference between this embodiment and the above embodiment is that: this embodiment provides another shape and structure for the dosing platform 2 and the protective pad 5, that is, the dosing platform 2 in this embodiment does not have chamfered corners on both sides, and the protective pad 5 is a planar structure.

[0056] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
