Abstract
Description
Technical Field
[0001] This utility model relates to the field of constant weight weighing technology, specifically to a bracket for weighing filter membranes during drying. Background Technology
[0002] During the drying process, operators typically place the filter membrane in a petri dish to provide a relatively enclosed environment and prevent contamination. However, the enclosed space of the covered petri dish restricts airflow. As a result, the evaporated water vapor cannot escape quickly and accumulates inside the dish, leading to a higher water vapor concentration around the filter membrane. This slows down the diffusion of moisture from the membrane surface to the surrounding environment.
[0003] To accelerate the drying efficiency of filter membranes, existing technologies also employ open clamps to hold the membranes in place. For example, the filter membrane is fixed to a mesh clamp using clips. After the clips secure the membrane, it is exposed to the drying environment to the maximum extent, allowing air to circulate freely around it, thus accelerating the evaporation and diffusion of moisture.
[0004] However, the above-mentioned mesh clamps have the following defects in the actual process of fixing the filter membrane: on the one hand, in order to ensure the flatness of the filter membrane, it takes a lot of time to install or remove the filter membrane, which affects the overall drying efficiency; on the other hand, the clamping force of the clamps on the filter membrane is uneven, and there is concentrated stress at the clamping point, which makes it easy for the filter membrane to form wrinkles, thus affecting the drying effect of the filter membrane. Summary of the Invention
[0005] The purpose of this invention is to provide a support structure for the drying process of filter membranes, so as to facilitate the support and clamping of filter membranes, improve drying efficiency, and enhance drying effect.

The clamping frame is configured to open the drying chamber as the top cover and the bottom cover are opened, and to clamp the filter membrane in the drying chamber as the top cover and the bottom cover are closed.
[0008] Both the top cover and the bottom cover are provided with openings, which are connected to the drying chamber. The breathable mesh is installed at the openings and has breathable holes.
[0009] The top cover and the bottom cover are opened to open the drying cavity, and the filter membrane is conveniently and quickly placed and removed.
[0010] Preferably, the top cover and the bottom cover are connected through a hinge.
[0011] Preferably, a clamping groove is arranged on the inner wall of the opening, and the edge of the breathable mesh is embedded in the clamping groove.

[0025] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0026] As Figures 1-6 shown, the embodiments of the present application propose a bracket for filter membrane drying and weighing, aiming to reduce the clamping difficulty of the filter membrane, improve the drying efficiency and enhance the drying effect in the process of implementing the drying operation of the filter membrane.
[0027] The bracket for filter membrane drying and weighing in the embodiments of the present application improves the convenience and stability of placing the filter membrane in the drying cavity by opening and closing the top cover and the bottom cover. The drying cavity can be opened by opening the top cover and the bottom cover, so that the filter membrane can be placed and removed quickly. The filter membrane can be clamped stably by closing the top cover and the bottom cover, so that the displacement or falling of the filter membrane in the drying and weighing process is avoided. At the same time, the opening connected with the drying cavity is arranged on the top cover and the bottom cover, and the air-permeable mesh with air holes is installed, so that the air in the drying cavity can flow fully in the drying process, the evaporation of water is accelerated, the drying efficiency is greatly improved, the uniformity of the filter membrane drying is ensured, and the drying effect is improved.
[0028] As Figure 1 shown, a bracket for filter membrane drying and weighing includes a clamping frame 1 and an air-permeable mesh 2.
[0029] As Figure 2 shown in combination Figure 4 , the clamping frame 1 includes a top cover 11 and a bottom cover 12. A drying cavity 3 for placing the filter membrane is arranged between the top cover 11 and the bottom cover 12. As Figure 1 shown in combination Figure 5 , the clamping frame 1 is configured to open the drying cavity 3 by opening the top cover 11 and the bottom cover 12, and to clamp the filter membrane in the drying cavity 3 by closing the top cover 11 and the bottom cover 12.
[0030] As Figure 3 shown in combination Figure 4As shown in the drawings, the top cover 11 and the bottom cover 12 are both provided with an opening 6. The opening 6 is in communication with the drying cavity 3. The air-permeable mesh 2 is installed at the opening 6. The air-permeable mesh 2 is provided with air-permeable holes.
[0031] As shown in the drawings, the top cover 11 and the bottom cover 12 are connected through a hinge 4. In use, the operator only needs to rotate the top cover 11 to open or close the drying cavity 3, greatly saving the operation time and improving the work efficiency. Figure 3
[0032] And the hinge 4 is arranged to have a rotating shaft between the top cover 11 and the bottom cover 12, ensuring that the top cover 11 always moves along the predetermined track during the opening and closing process. When the top cover 11 is closed, it can be accurately aligned with the bottom cover 12, ensuring the accurate clamping position of the filter membrane and avoiding damage to the filter membrane or inaccurate drying and weighing results due to position deviation. The hinge 4 is connected to provide stable support while effectively reducing the shaking of the top cover 11 during use, enhancing the stability of the entire bracket.
[0033] Among them, the opening and closing angle of the hinge 4 can be selected as 90 degrees, 110 degrees, 135 degrees, 165 degrees and 180 degrees according to actual use requirements. For example, the opening and closing angle of the hinge 4 is 180 degrees. The 180-degree opening and closing angle can make the top cover 11 completely flat, so that the drying cavity 3 is completely open, greatly widening the operation space. The operator can more easily and accurately put or take out the filter membrane, avoiding damage such as scratching and folding of the filter membrane when operating in a small space, protecting the integrity of the filter membrane and improving the accuracy of the drying and weighing results.
[0034] As shown in the drawings, the top cover 11 and the bottom cover 12 are connected through a hinge 4. In use, the operator only needs to rotate the top cover 11 to open or close the drying cavity 3, greatly saving the operation time and improving the work efficiency. Figure 4 As shown in the drawings, the top cover 11 and the bottom cover 12 are connected through a hinge 4. In use, the operator only needs to rotate the top cover 11 to open or close the drying cavity 3, greatly saving the operation time and improving the work efficiency. Figure 6 As shown in the drawings, the top cover 11 and the bottom cover 12 are connected through a hinge 4. In use, the operator only needs to rotate the top cover 11 to open or close the drying cavity 3, greatly saving the operation time and improving the work efficiency.
[0035] According to some preferred embodiments of the present application, the air-permeable mesh 2 is provided with a protruding part. The protruding part is configured to protrude outward from the inside of the drying cavity 3 at the opening 6, expanding the capacity of the drying cavity 3. The design of the protruding part provides more sufficient drying space for the filter membrane, enabling the filter membrane to be more fully contacted with hot air during the drying process, improving the drying effect.
[0036] In addition, the protruding part protruding outward from the inside of the drying cavity 3 changes the flow path of the air flow, prompting the hot air to form a more reasonable circulation in the drying cavity 3. The hot air generates turbulence when passing through the protruding part, increasing the contact area and time with the filter membrane, further improving the drying efficiency, and also helping to quickly take out the water vapor generated during the drying process from the drying cavity 3, improving the drying effect.
[0037] For example, the air-permeable mesh 2 is made of stainless steel wire. The air-permeable mesh 2 made of stainless steel wire has high strength and toughness and can withstand repeated installation, disassembly and external forces such as friction and collision during use, greatly prolonging the service life of the air-permeable mesh 2. Moreover, the stainless steel wire has good corrosion resistance to common chemicals such as acids and bases, can effectively resist corrosion, and ensures that the air-permeable mesh 2 can maintain structural integrity and air permeability in complex working environments.
[0038] As shown in Figure 3 , the air-permeable holes are uniformly distributed on the surface of the air-permeable mesh 2. The uniform distribution of the air-permeable holes can ensure that the air flow intensity and flow rate of each area remain consistent when the hot air passes through the air-permeable mesh 2 into the drying cavity 3, effectively improving the uniformity of the filter membrane drying, ensuring the stability of the drying quality, creating a more ideal air flow environment for filter membrane drying, and further improving the drying efficiency.
[0039] The bracket for filter membrane drying and weighing proposed in the embodiments of the present utility model can be used as shown in Figure 5 , the top cover 11 and the bottom cover 12 are both circular rings, and the top cover 11 and the bottom cover 12 are installed together through the hinge 4. The operator places the bracket on a stable, dry and well-ventilated workbench, holds the top cover 11, opens it to 180 degrees through the hinge 4, and makes the drying cavity 3 completely open. Then the filter membrane to be dried and weighed is placed in the drying cavity 3, ensuring that the filter membrane is placed flat without folding, curling and other conditions. Close the top cover 11 to make the top cover 11 tightly fit with the bottom cover 12, and accurately position through the hinge 4 to stably clamp the filter membrane. During the drying process, the air-permeable mesh 2 allows the hot air to enter the drying cavity 3 uniformly and stably, and the filter membrane is dried uniformly and comprehensively.
[0040] The bracket for filter membrane drying and weighing proposed in the embodiments of the present utility model can also be used with the drying and constant weight integrated detection equipment, and the clamping frame 1 provides stable support for the filter membrane, which facilitates the automatic mechanical hand to transfer the filter membrane through the clamping frame 1.
[0041] The utility model is not limited to the specific technical scheme described in the above embodiment, in addition to the above embodiment, the utility model can have other implementation manners. For the person skilled in the art, any modification, equivalent replacement, improvement etc. of the technical scheme formed within the spirit and principle of the utility model should be included in the protection scope of the utility model.
