Abstract
Description
Technical Field
[0001] This utility model relates to the field of sodium carbonate storage technology, and more specifically, to a sodium carbonate load-bearing silo that prevents caking. Background Technology
[0002] In chemical production and many industrial sectors involving the storage and transportation of powder materials, sodium carbonate is an important basic chemical raw material. Its stable and efficient storage and supply are crucial to ensuring the continuity of the production process. Currently, the industry widely uses load-bearing silos as the main storage equipment for sodium carbonate to ensure that the needs of large-scale production and immediate supply can be met. However, due to the strong hygroscopicity and easy agglomeration properties of sodium carbonate, hard lumps are easily formed inside the silo during long-term storage, especially under conditions of high humidity or large temperature fluctuations. These lumps not only occupy storage space and reduce the effective utilization rate of the silo, but also affect the normal unloading and transportation efficiency of sodium carbonate.
[0003] Existing load-bearing silos generally adopt nitrogen-filled protection measures, which involves continuously introducing nitrogen into the silo during its use. The drying properties of nitrogen and the absence of oxygen in the silo inhibit the hygroscopic and oxidation reactions of sodium carbonate to a certain extent, thereby slowing down or delaying the occurrence of caking. This nitrogen-filled anti-caking method has indeed played a positive role to a certain extent and has become the mainstream solution in the industry.
[0004] Although nitrogen purging can prevent sodium carbonate from caking, sodium carbonate is in a relatively static state in the silo, with particles tightly packed together and lacking an effective dynamic dispersion mechanism. Under these circumstances, even if nitrogen is continuously purged, it can only act on the surface area of the silo and cannot penetrate into the deeper layers of the aggregate. For caking that has already formed, a simple nitrogen atmosphere cannot exert enough physical force to break it up, causing the caking problem to gradually worsen over time. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a sodium carbonate load-bearing silo with anti-caking properties, so as to solve the problem that the lack of an effective dynamic dispersion mechanism in the prior art makes it difficult for nitrogen to penetrate to a deep layer, thereby affecting the performance of the load-bearing silo.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sodium carbonate load-bearing silo with anti-caking properties, comprising a silo body, wherein auger conveyors are installed on both the front and rear sides of the bottom of the silo body, a nitrogen filling port is fixedly installed on the upper right side of the auger conveyor, a sleeve shaft is rotatably connected to the inner wall of the silo body, a fixed shaft is inserted into the middle of the sleeve shaft, one set of stirring rods is installed on the outer side of the sleeve shaft, another set of stirring rods is installed on the lower outer side of the fixed shaft, a support frame is fixedly installed on the lower outer side of the fixed shaft, and scrapers are installed on both the left and right sides of the support frame.
[0007] The hopper body has a motor fixedly installed at the top, a rotating groove is opened at the top of the hopper body, a bevel gear one is rotatably connected to the upper side of the inner wall of the rotating groove, a bevel gear two is rotatably connected to the left side of the inner wall, and a bevel gear three is rotatably connected to the bottom of the inner wall.
[0008] The output end of the motor passes through the top wall of the rotating slot and is fixedly installed with bevel gear one. One side of bevel gear two is meshed with bevel gear one, and the other side is meshed with bevel gear three.
[0009] The top end of the sleeve shaft penetrates the bottom wall of the rotating groove and is fixedly installed between it and the bottom of the bevel gear three. The top end of the fixed shaft penetrates the bevel gear three and is fixedly installed between it and the bevel gear one.
[0010] The support frame has movable grooves on both the left and right sides of its inner wall. A movable plate is slidably connected to the inner wall of the movable groove, and multiple elastic elements are fixedly installed on the side of the movable plate near the fixed shaft.
[0011] The elastic element is fixedly installed on the inner wall of the moving groove at one end near the fixed shaft, and the scraper passes through the moving groove on the side near the fixed shaft and is fixedly installed with the moving plate.
[0012] The support frame is rotatably connected to the lower inner wall of the silo body, the scraper is attached to the inner wall of the silo body on the side away from the fixed axis, and the stirring rod is rotatably connected to the inner wall of the silo body.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In the above scheme, by rotating the drive shaft and the fixed shaft in opposite directions, the two sets of stirring rods are driven to disperse the sodium carbonate in the silo and, together with the nitrogen filling effect, enhance the anti-caking effect. At the same time, the scraper is used to scrape the inner wall of the silo, effectively reducing the amount of material residue on the inner wall of the silo during the feeding process, thereby optimizing the use efficiency and performance of the load-bearing silo.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0024] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a sodium carbonate load-bearing silo with anti-caking properties, comprising a silo body 1, with auger conveyors 2 installed on both the front and rear sides of the bottom of the silo body 1, a nitrogen filling port 3 fixedly installed on the upper right side of the auger conveyor 2, a sleeve shaft 4 rotatably connected to the inner wall of the silo body 1, a fixed shaft 5 inserted into the middle of the sleeve shaft 4, a set of stirring rods 7 installed on the outer side of the sleeve shaft 4, and another set of stirring rods 7 installed on the lower outer side of the fixed shaft 5, each set of stirring rods 7 consisting of eight individual stirring rods 7, so as to stir the sodium carbonate in the silo body 1. The supporting frame 6 is fixedly installed on the lower outer side of the fixed shaft 5. Scrapers 13 are installed on both the left and right sides of the supporting frame 6. The supporting frame 6 is rotatably connected to the lower inner wall of the silo body 1. The side of the scraper 13 away from the fixed shaft 5 is in contact with the inner wall of the silo body 1. Thus, when the supporting frame 6 rotates, it drives the scrapers 13 on both sides to scrape the inner wall of the silo body 1. The stirring rod 7 is rotatably connected to the inner wall of the silo body 1. Thus, the sodium carbonate in the silo body 1 is dispersed by the two sets of stirring rods 7. And through the coaxial reverse action, the anti-caking effect is improved.
[0025] During use, the sleeve shaft 4 and the fixed shaft 5 are first rotated in opposite directions to make the two sets of stirring rods 7 coaxially reversed and disperse the sodium carbonate in the silo body 1. At this time, in conjunction with the nitrogen filling port 3 on the auger conveyor 2, the caking of sodium carbonate in the silo body 1 is reduced, thereby improving the use effect of the silo body 1 and increasing the anti-caking performance. When discharging, the rotation of the fixed shaft 5 will drive the support frame 6 to rotate synchronously, and the support frame 6 is equipped with scrapers 13 on both sides. The scrapers 13 are used to scrape the inner wall of the silo body 1, thereby reducing the sodium carbonate adhering to the inner wall of the silo body 1, thereby improving the discharging effect and increasing the use performance of the silo body 1.
[0026] Example 2: Based on Example 1, in order to achieve coaxial reverse rotation of the two sets of stirring rods 7, a motor 8 is fixedly installed at the top of the hopper body 1. A rotating groove 9 is opened in the upper part of the hopper body 1. A bevel gear 10 is rotatably connected to the upper side of the inner wall of the rotating groove 9, a bevel gear 2 11 is rotatably connected to the left side of the inner wall, and a bevel gear 3 12 is rotatably connected to the bottom of the inner wall. The output end of the motor 8 passes through the top wall of the rotating groove 9 and is fixedly installed between it and the bevel gear 10. One side of the bevel gear 2 11 is meshed with the bevel gear 10, and the other side... The side is meshed with the bevel gear 12, so that when the motor 8 drives the bevel gear 10 to rotate, the bevel gear 2 11 drives the bevel gear 12 to rotate in the opposite direction to the bevel gear 10, which in turn drives the sleeve shaft 4 and the fixed shaft 5 to rotate in the opposite direction. The top end of the sleeve shaft 4 passes through the bottom wall of the rotating groove 9 and is fixedly installed between the bottom of the bevel gear 12 and the top end of the fixed shaft 5 passes through the bevel gear 12 and is fixedly installed between the bevel gear 10, so as to synchronously drive the two sets of stirring rods 7 to rotate in the opposite direction to increase the dispersing effect.
[0027] The start motor 8 drives the bevel gear 10 at its output end to rotate. At the same time, the bevel gear 2 11 meshing with it drives the bevel gear 3 12 to rotate in the opposite direction, thereby driving the sleeve shaft 4 and the fixed shaft 5 to rotate in the opposite direction, so that the two sets of stirring rods 7 can achieve coaxial reversal and increase the effect of dispersing sodium carbonate.
[0028] Example 3: Based on Example 2, in order to maintain the fit between the scraper 13 and the hopper body 1, the inner walls of the support frame 6 are provided with movable grooves 14 on both the left and right sides. The inner walls of the movable grooves 14 are slidably connected with movable plates 15, which can also play a limiting role to prevent the scraper 13 from detaching from the support frame 6. Multiple elastic elements 16 are fixedly installed on the side of the movable plate 15 near the fixed shaft 5. The end of the elastic element 16 near the fixed shaft 5 is fixedly installed on the inner wall of the movable groove 14. The scraper 13 near the fixed shaft 5 passes through the movable groove 14 and is fixedly installed with the movable plate 15. Thus, the elastic force of the elastic element 16 pushes the movable plates 15 on both sides to slide backwards, and drives the scraper 13 to fit with the hopper body 1.
[0029] Since three elastic elements 16 are installed on the inner walls of the moving grooves 14 on both sides of the support frame 6, their elasticity drives the moving plates 15 on both sides to slide backward along the inner wall of the moving grooves 14, and drives the scraper 13 to keep in contact with the inner wall of the hopper body 1, thereby improving the scraping effect of the scraper 13 and reducing the adhesion of sodium carbonate.
[0030] The working process of this utility model is as follows:
[0031] In use, the motor 8 is started first to drive the bevel gear 10 at its output end to rotate. At the same time, the bevel gear 11 meshing with it drives the bevel gear 12 to rotate in the opposite direction, thereby driving the sleeve shaft 4 and the fixed shaft 5 to rotate in the opposite direction, so that the two sets of stirring rods 7 can achieve coaxial reversal and disperse the sodium carbonate in the silo body 1. At this time, in conjunction with the nitrogen filling port 3 on the auger conveyor 2, the caking of sodium carbonate in the silo body 1 is reduced, thereby improving the use effect of the silo body 1 and increasing the anti-caking performance. When discharging, the rotation of the fixed shaft 5 will drive the support frame 6 to rotate synchronously. And the inner walls of the moving grooves 14 on both sides of the support frame 6 are equipped with three elastic elements 16. The elastic force drives the moving plates 15 on both sides to slide backward along the inner wall of the moving grooves 14, and drives the scraper 13 to keep in contact with the inner wall of the silo body 1, thereby reducing the sodium carbonate adhering to the inner wall of the silo body 1, thereby improving the discharging effect and increasing the use performance of the silo body 1.
