Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical reagent storage technology, specifically to a chemical reagent drying and storage device. Background Technology
[0002] Chemical reagents are fundamental substances used in scientific research, industrial production, medical diagnosis, education and teaching for chemical reactions, analysis and detection, substance synthesis and purification. They are diverse in type and properties and are widely used in laboratories, factories and medical settings. Some chemical reagents need to be stored in a dry and oxygen-free environment, which places high demands on storage devices.
[0003] The storage device for chemical reagents described in publication number CN216582023U includes a drying mechanism mounted on the tank. The drying mechanism consists of a drying tube, several drying holes, drying particles, and a third sealing cover. Through the action of the drying mechanism, powdered chemical reagents can be continuously and effectively dried, facilitating the replacement of the dried material and ensuring the drying effect. However, the existing technology still has shortcomings:
[0004] 1. Existing technologies rely on physical adsorption of dry particles and water-absorbing resins, which not only results in slow dehumidification and drying speeds, but also in the fact that the drying tube is a straight tube installed inside the tank. When the tank is full of chemical reagents, the drying tube will be buried, resulting in only a small portion of the chemical reagents in contact with the drying tube achieving a good drying and dehumidification effect. The moisture in the remaining chemical reagents cannot be adsorbed, making it impractical.
[0005] 2. Existing technology can only dry the inside of the tank, but cannot vacuum the inside. However, some chemical reagents need to be stored in a vacuum environment, as they are easily oxidized in the air, which is not conducive to the preservation of the reagents.
[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0007] The technical problem to be solved by this utility model is to address the above-mentioned issues and provide a chemical reagent drying and storage device.
[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a chemical reagent drying and storage device, including a storage box, a frustum-shaped discharge port provided at the bottom of the storage box, a support frame provided on the lower side of the discharge port, and further including:
[0009] The drying mechanism, located inside the storage tank, includes a vacuum pump, a first connecting pipe, a merging pipe, a drying pipe, a splitting pipe, a second connecting pipe, a heating box, through holes, and an activated carbon breathable mesh. The vacuum pump is located at the upper front end of the storage tank. The first connecting pipe is fixedly connected to the air inlet of the vacuum pump. The lower end of the first connecting pipe extends into the storage tank and is connected to the merging pipe. The merging pipe is fixedly connected between the two sides inside the storage tank. Several evenly distributed drying pipes are arranged at the lower part of the merging pipe. The drying pipes are serpentine and their rear ends penetrate the storage tank. The splitting pipe is fixedly connected between the rear ends of the drying pipes. The second connecting pipe is fixedly connected to the middle of the upper part of the splitting pipe. The heating box is located at the upper rear end of the storage tank. The upper end of the second connecting pipe is connected to the lower rear end of the heating box. Several evenly distributed through holes are opened on the surface of the drying pipes, and the activated carbon breathable mesh is disposed inside the through holes.
[0010] As an improvement, an electric heating tube is provided at the upper part of the heating box, a dustproof mesh plate is provided at the lower part of the electric heating tube, and a silicone mesh plate is provided at the lower part of the dustproof mesh plate. The dustproof mesh plate and the silicone mesh plate are respectively fixedly connected to the heating box.
[0011] As an improvement, a fan is provided on the upper part of the heating box, and the air outlet of the fan is connected to the inside of the heating box.
[0012] As an improvement, valve one is installed on the upper part of the connecting pipe one, and valve two is installed on the lower part of the connecting pipe two.
[0013] As an improvement, a feed inlet is provided in the middle of the upper part of the storage box, a sealing cover is provided above the feed inlet, and a sealing cover is provided below the discharge outlet.
[0014] The advantages of this utility model compared with the prior art are as follows: 1. This utility model sets up a drying mechanism that connects multiple serpentine drying tubes inside the storage box through a diversion pipe, which allows the chemical reagents inside the storage box to fully contact the surface of the drying tubes. Air is blown into the heating box by a fan, and after being heated by an electric heating tube, the hot air passes through a dust removal mesh and a silicone mesh to filter out dust and moisture before entering the drying tube through the connecting pipe 2. Then, it is blown onto the chemical reagents through through holes and an activated carbon breathable mesh, thereby quickly drying the chemical reagents, improving drying efficiency, and maintaining a good and uniform drying effect, which greatly improves practicality.
[0015] 2. After the chemical reagents are dried, valve two is closed and valve one is opened. The vacuum pump is started and works with the drying tube, through hole, confluence tube and connecting tube one to extract the air inside the storage box, so that the inside of the storage box is kept in a vacuum environment, which avoids some chemical reagents from being rapidly oxidized in the air and is conducive to the long-term effective preservation of chemical reagents.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.
[0022] Combined with appendix Figure 1-4 The present invention is provided with a storage box 1, a frustum-shaped discharge port 2 at the bottom of the storage box 1, a support frame 3 at the lower side of the discharge port 2, a feed port 11 at the middle of the upper part of the storage box 1, a sealing cover 12 at the top of the feed port 11, and a sealing cover 13 at the bottom of the discharge port 2, which can keep the internal environment of the storage box 1 isolated from the external environment.
[0023] A drying mechanism 4 is installed inside and outside the storage box 1, including a vacuum pump 401, a first connecting pipe 402, a merging pipe 403, a drying pipe 404, a splitting pipe 405, a second connecting pipe 406, a heating box 407, a through hole 408, and an activated carbon breathable mesh 409. The vacuum pump 401 is installed at the upper front end of the storage box 1. The vacuum pump 401 is equipped with a pressure gauge (not shown in the figure) to detect the vacuum status inside the storage box 1. The air inlet of the vacuum pump 401 is fixedly connected to the first connecting pipe 402, and the lower end of the first connecting pipe 402 extends to... The storage box 1 is connected to a merging pipe 403, which is fixedly connected between the two sides inside the storage box 1. The connection between the connecting pipe 402 and the storage box 1 is sealed with sealant. Several evenly distributed drying pipes 404 are provided at the bottom of the merging pipe 403. There are four drying pipes 404. The drying pipes 404 are serpentine and made of stainless steel, which has good stability. The drying pipes 404 can completely fill the interior of the storage box 1 and fully contact the chemical reagents, thereby improving the drying efficiency and effect and making the chemical reagents dry more evenly.
[0024] The rear end of the drying tube passes through the storage box 1 and the connection with the storage box 1 is sealed with sealant. A diversion tube 405 is fixedly connected between the rear ends of the drying tube 404. A connecting tube 406 is fixedly connected to the middle of the upper part of the diversion tube 405. A heating box 407 is set at the upper rear end of the storage box 1. The upper end of the connecting tube 406 is connected to the lower rear end of the heating box 407. Several evenly distributed through holes 408 are opened on the surface of the drying tube 404. An activated carbon filter and a breathable mesh 409 are set inside the through holes 408. The activated carbon filter and a breathable mesh 409 can adsorb water vapor in the chemical reagents. The mesh diameter is less than 10 micrometers, which can effectively prevent powdered or particulate chemical reagents from entering the interior of the drying tube 404.
[0025] An electric heating tube 5 is installed at the upper part of the heating chamber 407. A dustproof mesh plate 6 is installed below the electric heating tube 5. A silicone mesh plate 7 is installed below the dustproof mesh plate 6. The dustproof mesh plate 6 and the silicone mesh plate 7 are fixedly connected to the heating chamber 407. A fan 8 is installed at the upper part of the heating chamber 407. The air outlet of the fan 8 is connected to the interior of the heating chamber 407. A valve 9 is installed at the upper part of the connecting pipe 1 402. A valve 10 is installed at the lower part of the connecting pipe 2 406. Air is blown into the heating chamber 407 by the fan 8. After being heated by the electric heating tube 5, the hot air passes through the dustproof mesh plate 6 and the silicone mesh plate 7 to filter out dust and moisture. Then, it enters the drying tube 404 through the connecting pipe 2 406 and is blown onto the chemical reagent through the through hole 408 and the activated carbon breathable mesh 409, thereby quickly drying the chemical reagent.
[0026] After the chemical reagents are dried, valve 10 is closed and valve 9 is opened. Vacuum pump 401, together with drying tube 404, through hole 408, confluence tube 403 and connecting tube 402, draws air from the inside of storage box 1, keeping the inside of storage box 1 in a vacuum environment. This prevents some chemical reagents from oxidizing rapidly in the air and is conducive to the long-term effective preservation of chemical reagents.
[0027] In specific implementation of this utility model, such as Figure 1 As shown, open the sealing cover 12 and add chemical reagents into the storage tank 1 through the feed port 11. Start the fan 8 to blow air into the heating box 407. Start the electric heating tube 5 to heat the air. The airflow moves downward and passes through the dust removal mesh plate 6 and the silicone mesh plate 7 to filter out dust and moisture. Then, it enters the drying tube 404 through the connecting pipe 406 and blows onto the chemical reagents through the through hole 408 and the activated carbon breathable mesh 409, thus quickly and evenly drying the chemical reagents. After the reagents are dried, close the sealing cover 12 again, close the valve 10 and open the valve 9. Start the vacuum pump 401 and work with the drying tube 404, through hole 408, confluence pipe 403 and connecting pipe 402 to extract air from the storage tank 1. Observe the air pressure gauge until the storage tank 1 is evacuated to a vacuum state. Then close the valve 9 to dry and preserve the chemical reagents for a long time.
