Description

Technical Field

[0001] This utility model relates to the field of sodium metabisulfite production technology, specifically to an anti-caking sodium metabisulfite storage tank. Background Technology

[0002] Sodium metabisulfite, as an important chemical raw material, is widely used in many fields such as food processing, textile printing and dyeing, papermaking, and pharmaceuticals. Currently, storage containers are the main containers for storing sodium metabisulfite, and their performance directly affects the quality assurance and safety of sodium metabisulfite in use, occupying a key position in the entire storage process.

[0003] Existing sodium metabisulfite storage tanks mostly adopt a traditional cylindrical container design with a sealing cap at the inlet to isolate it from the external environment. However, in actual use, gaps easily appear at the connection between the sealing cap and the tank body due to wear and tear over long-term use or aging of the seals. Humid air from the outside can seep into the tank through these gaps. Sodium metabisulfite is highly hygroscopic; once it comes into contact with humid air, it quickly absorbs moisture, causing the particles to stick together, clump together, and eventually form caking. Caking not only destroys the original physical form of sodium metabisulfite but also alters its chemical properties, resulting in a decline in quality and severely affecting its subsequent use in various fields. Therefore, we propose an anti-caking sodium metabisulfite storage tank to effectively solve the above-mentioned drawbacks. Utility Model Content

[0004] The purpose of this invention is to provide an anti-caking sodium metabisulfite storage tank to solve the problem of sodium metabisulfite easily caking in the prior art as mentioned in the background section.

[0005] This utility model is achieved through the following technical solution: a storage tank for anti-caking sodium metabisulfite, including a tank body, with a feed inlet penetrating through the top of the tank body, and a fan-shaped shell located around the feed inlet detachably connected to the top of the tank body, with a feed pipe aligned with the feed inlet fixed to the top of the fan-shaped shell.

[0006] An arc-shaped stop is movably arranged inside the sector-shaped shell, and the central axis of the arc-shaped stop is the same as the central axis of the sector-shaped shell; a material discharge port and a dehumidification port are interspersed along the circumferential direction on the arc-shaped stop, and a dehumidification component is arranged inside the dehumidification port;

[0007] A rotating assembly is provided at the central axis of the fan-shaped housing. The rotating assembly is used to drive the arc-shaped stop block to rotate along the central axis so that the discharge port or dehumidification port is aligned with the feed pipe.

[0008] Optionally, the bottom of the fan-shaped shell is open, and a flange is fixed at the outer edge of the bottom of the fan-shaped shell. The flange is fixed to the outer top of the barrel by screws.

[0009] Optionally, the dehumidification assembly includes a desiccant placement cylinder detachably connected to the dehumidification port. The upper end of the desiccant placement cylinder is open, and a breathable mesh plate located at the upper end of the desiccant placement cylinder is embedded in the upper end of the arc-shaped baffle.

[0010] Optionally, the desiccant placement cylinder has a flange at the lower outer edge, and an installation groove adapted to the flange is provided at the bottom of the arc-shaped stop block. The flange is fixed in the installation groove by screws.

[0011] Optionally, the rotating assembly includes a rotating shaft rotatably connected to the central axis of the sector-shaped housing, a fixing ring fixed at the lower end of the rotating shaft and located inside the sector-shaped housing, and a plurality of fixing rods fixedly connected between the fixing ring and the arc-shaped stop.

[0012] Optionally, magnets are fixed at both ends of the arc-shaped stop, and magnetic blocks corresponding to each magnet are fixed on the inner side of the fan-shaped housing.

[0013] Compared with the prior art, this utility model provides an anti-caking sodium metabisulfite storage tank, which has the following beneficial effects:

[0014] This invention utilizes the coordinated structure of an inlet, a fan-shaped shell, an inlet pipe, an arc-shaped baffle, a discharge port, a dehumidification port, a dehumidification component, and a rotating component. When sodium metabisulfite is to be added, the inlet pipe, inlet, and discharge port can be aligned to ensure smooth material entry into the container. After feeding, the rotating component drives the arc-shaped baffle to rotate, aligning the dehumidification port with the inlet pipe. The dehumidification component then dries the air inside the inlet pipe, effectively preventing moisture from entering the container. This design effectively solves the problems of insufficient sealing and easy moisture accumulation in traditional storage containers. Through an active moisture-proof mechanism, it significantly reduces the probability of sodium metabisulfite coming into contact with moisture, thus significantly improving the stability and safety of material storage.

[0022] 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.

[0023] Please see Figures 1 to 6 A storage tank for sodium metabisulfite with anti-caking properties includes a tank body 1 for storing sodium metabisulfite. A feed inlet 2 extends through the top of the tank body 1 for adding sodium metabisulfite into the tank body 1. A fan-shaped shell 3 is detachably connected to the top of the tank body 1, located around the feed inlet 2. A feed pipe 4, aligned with the feed inlet 2, is fixed to the top of the fan-shaped shell 3. A sealing cap (not shown in the figure) is fitted to the top of the feed pipe 4, allowing it to be sealed under normal conditions.

[0024] To prevent gaps from appearing in the sealing cap due to wear and tear or aging of the seals over long-term use, which could allow humid air to seep into the container and cause sodium metabisulfite to clump, the following design is implemented:

[0025] An arc-shaped stop 5 is movably disposed within the sector-shaped housing 3. The central axis of the arc-shaped stop 5 is the same as that of the sector-shaped housing 3, and the arc-shaped stop 5 can rotate along the central axis. A material discharge port 6 and a dehumidification port 7 are circumferentially spaced through the arc-shaped stop 5, and a dehumidification component 8 is disposed within the dehumidification port 7. A rotating component 12 is disposed at the central axis of the sector-shaped housing 3. The rotating component 12 is used to drive the arc-shaped stop 5 to rotate along the central axis so that the material discharge port 6 or the dehumidification port 7 is aligned with the feed pipe 4.

[0026] With the above design, when sodium metabisulfite needs to be added, the sealing cover is opened, and then the rotating component 12 drives the arc-shaped stop 5 to rotate clockwise so that the feed pipe 4, feed port 2 and discharge port 6 are aligned, ensuring that the material can smoothly enter the barrel 1.

[0027] After feeding is completed, a sealing cap is installed on the top of the feed pipe 4. Then, the rotating component 12 drives the arc-shaped baffle 5 to rotate counterclockwise so that the dehumidification port 7 is aligned with the feed pipe 4. If the seal at the top of the feed pipe 4 fails and outside air enters, the dehumidification component 8 can quickly dry it, effectively preventing moisture from entering the inside of the tank 1, thereby significantly reducing the probability of sodium metabisulfite coming into contact with moisture and preventing the sodium metabisulfite inside the tank 1 from clumping.

[0028] The following describes how the sector-shaped shell 3 is detachably connected to the barrel body 1:

[0029] The bottom of the fan-shaped shell 3 is open, allowing for easy maintenance of the internal components after removal. A flange 9 is fixed to the outer edge of the bottom of the fan-shaped shell 3, and the flange 9 is secured to the top of the barrel 1 with screws. The fan-shaped shell 3 is detachably connected to the barrel 1 via the flange 9 and screws. It should be noted that the junction between the flange 9 and the barrel 1 needs to be sealed to prevent outside air from entering the fan-shaped shell 3.

[0030] The following is an introduction to dehumidification component 8:

[0031] The dehumidification assembly 8 includes a desiccant container 801 detachably connected to the dehumidification port 7, allowing users to easily fill it with different types of desiccants such as silica gel and calcium chloride according to their actual needs. The upper end of the desiccant container 801 is open, facilitating quick replacement and addition of desiccant, effectively improving maintenance convenience. A breathable mesh plate 802 is embedded at the upper end of the desiccant container 801. When the position of the arc-shaped baffle 5 is adjusted by rotating the assembly 12 so that the dehumidification port 7 is aligned with the feed pipe 4, the air entering the feed pipe 4 will pass through the breathable mesh plate 802 and come into contact with the desiccant inside the container. During this process, the moisture in the air is quickly absorbed by the desiccant, forming a highly efficient moisture barrier, greatly reducing the possibility of humid air entering the container 1 through the feed port 2, creating a dry and stable storage environment for sodium metabisulfite, and effectively ensuring the quality of the material.

[0032] In this embodiment, the desiccant placement cylinder 801 has a flange 10 at its lower outer edge. A mounting groove 11, corresponding to the flange 10, is provided at the bottom of the arc-shaped stop block 5. The flange 10 is fixed to the mounting groove 11 by screws. The desiccant placement cylinder 801 can be detachably inserted into the dehumidification port 7 through the cooperation of the flange 10 and the screws. When the desiccant needs to be replaced, first remove the fan-shaped housing 3, then remove the screws on the flange 10, and the desiccant placement cylinder 801 can be pulled out from the dehumidification port 7. Since the upper end of the desiccant placement cylinder 801 is open, the desiccant inside can be poured out and new desiccant can be added.

[0033] The following is a description of the rotating component 12:

[0034] The rotating assembly 12 includes a rotating shaft 121 rotatably connected to the central axis of the sector-shaped housing 3. A fixing ring 122 located inside the sector-shaped housing 3 is fixed to the lower end of the rotating shaft 121. Several fixing rods 123 are fixedly connected between the fixing ring 122 and the arc-shaped stop block 5. Additionally, a handle located outside the sector-shaped housing 3 is fixed to the upper end of the rotating shaft 121. When the user holds the handle and rotates the rotating shaft 121, the arc-shaped stop block 5 rotates synchronously through the cooperation of the fixing ring 122 and the fixing rods 123, aligning the discharge port 6 or dehumidification port 7 with the feed pipe 4.

[0035] It is worth mentioning that magnets 13 are fixed at both ends of the arc-shaped stop 5, and magnetic blocks 14 corresponding to each magnet 13 are fixed on the inner side of the fan-shaped housing 3. When the arc-shaped stop 5 is rotated into position, the position of the arc-shaped stop 5 can be fixed by the cooperation of the magnets 13 and the magnetic blocks 14, so that the arc-shaped stop 5 is not easy to shake in the fan-shaped housing 3, ensuring that the discharge port 6 or the dehumidification port 7 can be accurately aligned with the feed pipe 4.

[0036] Working principle: During the feeding stage, the operator first opens the sealing cap at the top of the feed pipe 4, and then manually rotates the rotating shaft 121, causing the arc-shaped stop block 5 to rotate clockwise within the fan-shaped housing 3. As the rotating shaft 121 rotates, the discharge port 6 on the arc-shaped stop block 5 gradually aligns precisely with the feed inlet 2 and the feed pipe 4. At this time, sodium metabisulfite can be smoothly fed into the tank 1 sequentially through the feed pipe 4, the discharge port 6, and the feed inlet 2.

[0037] After feeding is completed, the sealing cap at the top of the feed pipe 4 is first tightly screwed or fastened to form the first line of defense. Then, the rotating shaft 121 is rotated counterclockwise, causing the arc-shaped stop block 5 to rotate counterclockwise within the fan-shaped housing 3 until the dehumidification port 7 is fully aligned with the feed pipe 4. At this point, the air inside the feed pipe 4 can fully contact the desiccant in the desiccant placement cylinder 801 via the breathable mesh plate 802. The desiccant, with its hygroscopic properties, quickly absorbs moisture from the air, effectively reducing air humidity. Even if there are minor gaps in the sealing cap causing a small amount of outside air to enter the feed pipe 4, after dehumidification by the desiccant, moisture is unlikely to enter the container 1, thus creating a dry and stable storage environment for the sodium metabisulfite inside the container 1, minimizing the risk of clumping due to moisture and ensuring the quality and safety of the sodium metabisulfite.
