Description

Technical Field

[0001] This invention relates to the field of soda ash storage technology, specifically a soda ash storage silo for photovoltaic glass production. Background Technology

[0002] Soda ash (sodium carbonate) is a core flux in photovoltaic glass production, with huge consumption and a high cost proportion. Against the backdrop of the rapid development of the photovoltaic industry, the supply chain management and warehousing technology of soda ash are particularly crucial. To cope with significant fluctuations in raw material market prices and reduce production costs, photovoltaic glass companies typically adopt a staggered procurement strategy, purchasing large quantities of soda ash when prices are low. This places extremely high demands on the capacity, sealing, and long-term stability of storage facilities. Currently, the industry commonly uses large steel silos or concrete storage silos to store soda ash. These facilities are usually equipped with pneumatic conveying systems, designed to create a closed environment that isolates external rainwater, dust, and moisture, enabling large-scale storage and automated transfer of raw materials.

[0003] Although existing storage equipment has solved the problem of soda ash storage to some extent, there are still obvious defects and shortcomings in actual production operation. First, because soda ash particles are highly hygroscopic, existing ordinary sealed silos cannot completely prevent the penetration of slight moisture. Long-term static storage will cause soda ash to absorb moisture and clump together severely at the bottom and walls of the silo, forming hard dead material, which will block the discharge channel and make discharge extremely difficult. Second, in order to achieve large-scale storage, storage silos are often designed to be high and deep. The material in the center is prone to forming compacted arch bridges, which are difficult to fall smoothly by gravity alone. Traditional single discharge ports or simple vibrators cannot effectively solve the problem of arching and bridging in deep silos. In addition, existing cleaning equipment can often only solve the problem of material adhering to the silo walls, and cannot take into account the dynamic activation and dispersal of the clumps in the center, resulting in a reduction in effective volume utilization and failing to meet the stringent requirements of modern production lines for continuous, uniform, and automated feeding. Summary of the Invention

[0004] The purpose of this invention is to provide a soda ash storage silo for photovoltaic glass production, in order to solve the problems mentioned in the background art, such as the inadequate moisture-proof sealing of existing soda ash storage silos and the lack of an efficient dynamic activation and arch-breaking mechanism inside, which lead to the raw materials easily absorbing moisture and clumping, and the discharge blockage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a soda ash storage silo for photovoltaic glass production, comprising: The storage silo is a vertically arranged cylindrical structure with a feed pipe on its top side wall and an exhaust pipe on the other side of its top for balancing air pressure. The inside of the storage silo is enclosed to form a storage cavity for storing soda ash raw materials. Multiple discharge bins are arranged in a circular array and fixedly connected to the bottom of the storage bin, and each discharge bin has a discharge chamber inside; A partition is fixedly connected between the storage chamber and the discharge chamber. The top surface of the partition has an upwardly convex arc-shaped flow guiding structure, which is used to receive the raw materials in the storage chamber and disperse and guide them to the top of each of the discharge chambers around it. Multiple processing units are movably arranged in a circular array within the storage chamber, with the bottom of each processing unit extending into the corresponding discharge chamber. The processing units are configured to agitate, stir, heat, and dehumidify the raw materials. A mixing element is provided in each discharge chamber. The mixing element is sleeved on the outside of the processing element and is used to cooperate with the processing element to perform secondary mixing and anti-wall adhesion treatment on the raw materials in the discharge chamber. A drive assembly is mounted on top of the storage bin. The output end of the drive assembly is connected to the processing component for driving the processing component to rotate around its own axis and to perform high-frequency reciprocating vibration along the axial direction.

[0006] Furthermore, the processing component includes: A rotating rod is coaxially disposed inside the storage cavity. The top end of the rotating rod extends upward to the outside of the storage hopper, and the bottom end extends into the discharge cavity. The cross-section of the rotating rod is a polygonal non-circular structure. The first rotary cylinder is rotatably mounted on the top of the storage bin, and the rotary rod is slidably inserted into the inner hole of the first rotary cylinder; The second rotating cylinder is rotatably connected to the partition plate, and the rotating rod is slidably inserted into the inner hole of the second rotating cylinder; The heating elements are arranged in a linear array along the longitudinal direction of the rotating rod and are fixedly connected to the rod section of the rotating rod located in the storage cavity; The screw is coaxially fixed to the bottom end of the rotating rod and located inside the discharge pipe at the bottom of the discharge bin, used to force the raw material to be discharged when rotating.

[0007] Furthermore, the heating element includes: A connecting ring is coaxially sleeved and fixed to the outer side wall of the rotating rod; The heating strip has a three-dimensional wave-shaped extension structure. Multiple heating strips are arranged in a circular array around the axis of the rotating rod, and the two ends of each heating strip are fixedly connected between the connecting ring and the rotating rod. The heating strip revolves and rotates synchronously with the rotating rod, and generates axial micro-vibration under the drive of the rotating rod, so as to cut and break up the clumps of raw materials through the wave-like structure, and at the same time heat and dehumidify the raw materials evenly.

[0008] Furthermore, the stirring component includes: The third rotary cylinder is rotatably sleeved on the outside of the rod section of the rotary rod located in the discharge chamber, and can rotate voluntarily with the rotary rod; Multiple sets of connecting rods are radially and fixedly connected to the outer peripheral wall of the third rotary cylinder; Multiple scraping rods are arranged in a circular array and fit against the inner wall of the discharge chamber and are fixed to the connecting rod, so as to rotate synchronously with the third rotary drum and scrape off the soda ash material adhering to the chamber wall. In each group of connecting rods, the end furthest from the third rotary drum is fixedly connected to the corresponding scraper rod, so that when the third rotary drum rotates, it drives the scraper rod to scrape off the material adhering to the inner wall of the discharge chamber.

[0009] Furthermore, the stirring component also includes: The bracket is fixedly connected to the top inner wall of the discharge chamber. The top of the third rotary cylinder is rotatably supported at the center of the bracket by a bearing to maintain the coaxiality of the third rotary cylinder and the rotary rod.

[0010] Furthermore, the driving component includes: A rotating component, installed on top of the storage bin, is used to provide rotational driving force to the rotary rod; A vibrating element, installed on top of the storage bin, is used to provide a high-frequency reciprocating vibration force along the axial direction to the rotary rod.

[0011] Furthermore, the rotating component includes: The connecting frame is rotatably supported on the top of the storage bin via a pivot. The first toothed ring is coaxially fixedly connected to the outside of the connecting frame and can rotate voluntarily with the connecting frame; Multiple gears are coaxially and fixedly connected to the top outer periphery of the corresponding first rotating cylinder. Each gear meshes with the first gear ring so that when the first gear ring rotates, it synchronously drives each gear to rotate around its own axis. A servo motor is fixedly installed on the top of the storage bin, and its output shaft is connected to the rotating shaft of the connecting frame to drive the first gear ring to rotate and drive all gears and rotating rods to rotate synchronously.

[0012] Furthermore, the vibrating element includes: The support block, which has a U-shaped structure, is fixedly connected to the top wall of the storage bin; A vibration motor is fixedly installed on the top plate of the support block; A rotating block is fixedly connected to the output shaft end of the vibration motor. The bottom end of the rotating block is rotatably connected to the top end of the rotating rod to control the longitudinal vibration of the rotating rod.

[0013] Furthermore, the rotating component also includes: The second toothed ring is rotatably supported on the top inner side of the storage cavity and coaxially sleeved on the outer side of the gear, and the second toothed ring meshes with the gear; Multiple scraper rods are fixedly connected to the outer wall of the second toothed ring in a circular array, and the ends of the scraper rods are elastically attached to the inner wall of the storage chamber, for cleaning the storage chamber wall when the second toothed ring rotates.

[0014] Furthermore, it also includes: Multiple automatic connecting pipes, arranged in a circular array, are opened through the partition to connect the storage chamber and the discharge chamber; A push rod is fixedly connected to the bottom end of each scraper rod, and the bottom surface of the push rod slides against the upwardly protruding arc-shaped top surface of the partition. The pusher rod rotates synchronously with the scraper rod to push the raw material deposited at the center of the top surface of the partition outward along the arc-shaped slope, and force it into the discharge chamber through the automatic connecting pipe, so as to achieve uniform distribution and continuous feeding of the raw material.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This type of soda ash storage silo for photovoltaic glass production stores soda ash raw materials through a storage chamber formed by the storage silo. Multiple discharge silos arranged in a circular array at the bottom each have a discharge chamber. Arc-shaped guide baffles evenly guide the raw materials to the top of each discharge chamber, achieving large-capacity, zoned storage and uniform discharge. A drive assembly at the top of the storage silo rotates and vibrates the processing components within the storage chamber at high frequency. Combined with heating and dehumidification functions, this breaks up clumps and bridges, deeply prevents moisture, and improves the flowability and dryness of the raw materials. An agitator, fitted inside each discharge chamber and outside the processing components, prevents raw materials from adhering to the chamber walls and clogging the discharge, ensuring high utilization of the discharge chambers and smooth discharge. The entire process guarantees stable soda ash raw material quality and continuous production. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-9 As shown, the present invention provides a soda ash storage silo for photovoltaic glass production. This device mainly solves the technical problems of soda ash storage being prone to moisture absorption and clumping, difficult discharge, and unable to meet the needs of large-volume off-peak procurement in the prior art. The overall structure of the device includes core functional modules such as storage silo 1, multiple discharge silos 5, partition 7, multiple processing components 8, stirring components 9, and drive components 10.

[0020] The storage silo 1, serving as the main load-bearing structure of the entire device, is designed as a vertically arranged cylindrical steel body. The preferred inner diameter of the silo is 3.5–6.5 m, the effective height is 8–15 m, and the effective volume is 50–350 m³. 3Its interior is enclosed to form a large-volume storage chamber 4, which meets the demand of photovoltaic glass manufacturers for large-scale storage of soda ash, thereby coping with market price fluctuations and achieving low-price centralized procurement to lock in prices. A feed pipe 2 is provided on the top side wall of the storage silo 1. The feed pipe is made of 304 stainless steel with an inner diameter of 250-500mm and a wall thickness of 6-12mm. The feed pipe 2 is connected to an external pneumatic conveying pipeline or elevator. On the other side of the top of the storage silo 1, an exhaust pipe 3 is provided to balance the air pressure. The exhaust pipe has an inner diameter of 200-400mm and is equipped with a 0.1-0.5μm grade PTFE dust removal filter and a drying molecular sieve. In particular, in order to achieve a fully sealed moisture-proof structure on the top of the silo, the top of the silo, the feed port and the exhaust port are all strictly sealed. The overall sealing level reaches IP65. Fluororubber sealing strips are used at the joints, and the welded parts are continuously fully welded and epoxy resin anti-corrosion. It has the functions of rainproof, dustproof and moisture-proof. The relative humidity inside the silo can be stably controlled below 45%, thereby effectively preventing the soda ash from absorbing moisture and clumping, and ensuring the dryness and purity of the raw materials inside the silo. To prevent backflow of external moisture, the exhaust pipe 3 is also equipped with a drying filter and a one-way valve assembly to ensure that dust can be filtered when the gas is discharged from the chamber, and that external humid air cannot flow back into the chamber.

[0021] At the bottom of the storage silo 1, 3 to 8 discharge silos 5 are arranged in a circular array and fixedly connected. These discharge silos 5 divide the originally single discharge channel into multiple independent branches. Each discharge silo 5 has a discharge chamber 6 inside. The discharge silo cone angle is 55 to 75°, the inner wall is lined with a 5 to 10 mm thick ultra-high molecular weight polyethylene wear-resistant layer, and the surface roughness Ra≤6.3μm, which is used to extend the service life of the equipment and ensure that the raw materials are not contaminated by the silo wall. Between the storage chamber 4 and the discharge chamber 6, a partition 7 is fixedly installed. The partition 7 is 12 to 20 mm thick, the arc arch height is 300 to 800 mm, and the radius of curvature is 2.0 to 5.0 m. The top surface of the partition 7 has an upward convex arc-shaped flow guiding structure. This unique convex design can make full use of the gravitational potential energy of the material, so that the raw materials accumulated in the central area of ​​the storage silo 1 slide outwards and are dispersed and guided to the top of each discharge silo 5. The baffle 7 has 6 to 24 automatic connecting pipes 14 arranged in a circular array, each with an inner diameter of 150 to 300 mm, serving as the physical channel for raw materials to enter the discharge chamber 6 from the storage chamber 4. The upper end of the automatic connecting pipe 14 is equipped with an anti-jamming flare with a taper of 1:6 and a height of 80 to 150 mm. The lower end is equipped with a flexible guide port made of silicone material with a thickness of 3 to 5 mm, which prevents raw materials from bridging and clogging at the pipe opening and reduces dust generation during material descent. The joints between the arc-shaped guide baffle 7 and the inner wall of the storage chamber 1, as well as the joints of each discharge chamber 5, are all constructed using a continuous welding process and are equipped with annular sealing strips. The width of the annular sealing strips is 20 to 40 mm, and the Shore hardness is 60 to 70, completely preventing moisture from entering through the joint gaps and preventing localized moisture absorption of the raw materials. The storage chamber 4, formed by the storage silo 1, stores the raw materials for soda ash. Multiple discharge silos 5 arranged in a circular array at the bottom of the silo 1 each have a discharge chamber 6. With the help of arc-shaped guide baffles 7, the raw materials are evenly guided to the top of each discharge chamber 6, achieving large-capacity, zoned storage and uniform discharge. The drive assembly 10 at the top of the storage silo 1 drives the processing unit 8 inside the storage chamber 4 to rotate and vibrate at high frequency. Combined with heating and dehumidification functions, this breaks up clumps and bridges, deeply prevents moisture, and improves the flowability and dryness of the raw materials. The stirring unit 9, fitted inside each discharge chamber 6 and outside the processing unit 8, prevents the raw materials from adhering to the chamber wall and clogging the discharge, ensuring the utilization rate of the discharge chamber 6 and smooth discharge. The entire process guarantees stable raw material quality and continuous production of soda ash.

[0022] To achieve dynamic activation, arch breaking, and deep dehumidification of soda ash raw materials, processing components 8 are installed in the storage chamber 4 corresponding to the positions of each discharge bin 5. The number of processing components corresponds one-to-one with the discharge bins, and the axial spacing is 800-1500mm. These processing components 8 are distributed in a circular array. Each processing component 8 includes a rotating rod 801 that runs longitudinally through the storage chamber 4. The rotating rod is made of 42CrMo quenched and tempered steel. The rotating rod 801 has a diameter of 60-120mm, a length of 10-18m, a regular hexagonal cross-section, and a side-to-side distance of 60-120mm. The top end of the rotating rod 801 extends upward through the top of the storage bin 1, and the bottom end extends into the discharge chamber 6. To ensure the stability and sealing of the rotating rod 801 during rotation, a first rotating cylinder 802 is installed on the top of the storage bin 1, and a second rotating cylinder 803 is installed on the partition plate 7. The rotating rod 801 is slidably inserted into the inner holes of these two rotating cylinders. The cross-section of the rotating rod 801 is designed as a polygonal non-circular structure to ensure effective torque transmission. Graphite copper sleeves with a wall thickness of 8–15 mm and 3–5 lip seals are embedded in the inner holes of both the first rotating cylinder 802 and the second rotating cylinder 803. The lip seals are made of nitrile rubber with a wire diameter of 4–8 mm, which reduces the frictional resistance of the rotating rod 801 during rotation and vibration, and forms a multi-layer dynamic sealing structure to prevent moisture from entering through the gaps in the rod body.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, heating elements are linearly arrayed and fixedly connected along the longitudinal direction on the section of the rotating rod 801 located within the storage chamber 4. The axial spacing of the heating elements is 250–450 mm, and 6–12 groups are evenly distributed along the circumference of the rotating rod. Each heating element specifically includes a connecting ring 805 coaxially sleeved and fixed to the outer wall of the rotating rod 801. The connecting ring is 10–18 mm thick, has an outer diameter 80–150 mm larger than the rotating rod, and is made of 304 stainless steel. It also includes multiple heating strips 806 extending in a three-dimensional wave pattern. The wave amplitude of the heating strips is 50–120 mm, the wave pitch is 120–250 mm, the diameter is 12–20 mm, and the length of a single strip is 1.5–3.0 m. These heating strips 806 are distributed in a circular array around the axis of the rotating rod 801, and both ends are fixedly connected between the connecting ring 805 and the rotating rod 801. The heating strips 806 have built-in nickel-chromium alloy resistance wires with a power density of 2.5–4.5 W / cm². 2Rated voltage 220 / 380V, single unit power 0.8~2.5kW, total heating power 15~60kW, externally covered with 316L stainless steel pipe and high-temperature resistant mica insulation layer, temperature resistance ≥350℃, surface covered with high-temperature resistant and anti-corrosion coating, alkali resistance grade ≥10, which can maintain structural stability during rotation and vibration, and avoid direct contact with soda ash raw materials to avoid corrosion and pollution. When the device is working, the heating bar 806 is energized and heats up, with the heating temperature controlled between 45 and 75°C, a temperature control accuracy of ±2°C, and independent temperature control in each zone. Combined with the sealed environment of the chamber, it effectively dries the raw materials. More importantly, the heating bar 806 rotates at high speed synchronously with the rotating rod 801, with a speed of 30 to 80 r / min. Driven by the drive component 10, it generates high-frequency micro-amplitude vibration along the axial direction, with a vibration frequency of 15 to 50 Hz and an amplitude of 3 to 8 mm. During the rotation and vibration process, the wavy heating bar 806 physically cuts and shears the raw materials, effectively breaking up the clumps of soda ash and crushing hard lumps with a diameter ≤80 mm. This increases the contact area between the raw materials and the hot air, achieving the dual effects of physical dispersal and thermal dehumidification. At the bottom of the rotary rod 801, a screw 804 is coaxially fixedly connected. The screw has a diameter of 80-150mm, a length of 600-1200mm, and a pitch of 60-120mm. This screw 804 is located inside the discharge pipe 16 at the bottom of the discharge hopper 5. The discharge pipe has an inner diameter of 100-200mm and is equipped with a pneumatic gate valve and a flow regulating valve. As the core component of the quantitative unloading and screw conveying mechanism, it uses the screw conveying principle to force and uniformly discharge the activated and dried raw materials. The discharge capacity is 5-25t / h, with an adjustable range of 30%-100%, preventing blockage at the discharge port. The screw 804 has a variable pitch structure. The upper pitch is smaller to compact the activated raw materials (60-80mm), and the lower pitch gradually increases to reduce the discharge speed (90-120mm), preventing bridging of the raw materials at the discharge port or dust generation due to excessive flow velocity.

[0024] like Figure 2 , Figure 4 and Figure 6As shown, a set of agitators 9 is also installed inside each discharge chamber 6 to cooperate with the processing unit 8 for secondary agitation and cleaning of the chamber walls. The agitator 9 includes a third rotary cylinder 901 movably sleeved on the outside of the rotary rod 801. The inner diameter of the third rotary cylinder is 10-20 mm larger than that of the rotary rod, the length is 400-800 mm, and the material is 304 stainless steel. The third rotary cylinder 901 is rotatably supported on the top inner wall of the discharge chamber 6 by a bracket 904 to ensure that it maintains coaxiality with the rotary rod 801. Four to eight sets of connecting rods 902 are radially fixedly connected to the outer peripheral wall of the third rotary drum 901. The connecting rods have a diameter of 10 to 16 mm and a length of 150 to 300 mm. Each set of connecting rods 902 has a scraper rod 903 fixedly connected to its end. The scraper rod has a width of 30 to 60 mm and a thickness of 8 to 12 mm, and its curvature is consistent with the inner wall of the discharge hopper. The scraper rods 903 are distributed in a circular array, and their ends are attached to the inner side wall of the discharge cavity 6 through elastic elements. The ends of the scraper rods 903 are detachably equipped with wear-resistant polymer scrapers, which are 5 to 10 mm thick, have a Shore hardness of 75 to 85, and a service life of ≥8000 hours. This ensures the effective removal of adhering materials while avoiding damage to the anti-corrosion and wear-resistant lining of the inner wall of the discharge cavity 6. When the rotating rod 801 rotates and causes the material to tumble, the third rotating cylinder 901 rotates automatically under the action of the material friction force, with a rotation speed of 0.6 to 0.9 times that of the rotating rod. This, in turn, drives the scraper rod 903 to rotate along the inner wall of the discharge chamber 6, automatically removing the soda ash powder adhering to the silo wall. It can remove the wall layer with a thickness of ≤15mm, preventing long-term accumulation from forming hard lumps that reduce the effective volume.

[0025] like Figure 3 , Figure 5 , Figure 7 and Figure 8The drive assembly 10, as the power core of the entire device, is mounted on the top of the storage bin 1. It consists of two parts: a rotating component and a vibrating component, which are responsible for providing rotational power and axial vibration force, respectively. The rotating component mainly consists of a servo motor 1004, a connecting frame 1001, a first gear ring 1002, and a gear 1003. The servo motor has a power of 7.5-22kW, a rated speed of 1500-3000r / min, a reduction ratio of 15-40, and a protection level of IP54. The connecting frame 1001 is rotatably supported on the top of the storage bin 1 via a rotating shaft. The servo motor 1004 is fixed on the top of the bin, and its output shaft is connected to the rotating shaft of the connecting frame 1001. The first gear ring 1002 is fixed at the bottom of the connecting frame 1001. The outer diameter of the first gear ring is 1.2-2.5m, the module is 8-12, and the number of teeth is 80-160. Corresponding to the outer circumference of the top of the first rotating cylinder 802 of each processing component 8, a gear 1003 is coaxially fixed. The gear module matches the first gear ring, the number of teeth is 20-40, and the material is 40Cr quenched and tempered. These gears 1003 all mesh with the first gear ring 1002. When the servo motor 1004 starts, it drives the connecting frame 1001 and the first gear ring 1002 to rotate, which in turn drives the gear 1003 to rotate synchronously, and finally drives the rotating rod 801 to rotate synchronously. To achieve material level monitoring and early warning, a material level gauge 11 is fixedly installed at the bottom center of the connecting frame 1001. This material level gauge 11 rotates synchronously with the connecting frame 1001 and can scan the material level at multiple angles within the silo. The scanning radius is 3–6 m, the measurement accuracy is ±2%, and the range is 0–15 m. It displays inventory in real time, facilitating procurement planning and production scheduling. The material level gauge 11 is a rotary paddle level gauge or a radar level gauge with an IP67 protection rating and an operating temperature of -20–85℃. Contact or non-contact monitoring solutions can be selected according to different working conditions to improve the reliability of data acquisition.

[0026] like Figure 2 , Figure 7 and Figure 8The vibrating components include a support block 1005, a vibrating motor 1006, and a rotating block 1007. The vibrating motor has a power of 1.5 to 5.5 kW, an excitation force of 10 to 30 kN, a frequency of 15 to 50 Hz, an adjustable amplitude of 3 to 8 mm, and an IP65 protection rating. The support block 1005 has a U-shaped structure, a steel plate thickness of 12 to 20 mm, and is integrally welded. It is fixedly connected to the top wall of the storage bin 1 and serves as the mounting base for the vibrating motor 1006. The vibrating motor 1006 is fixed on the top plate of the support block 1005, and its output shaft end is fixedly connected to the rotating block 1007. The rotating block has an eccentricity of 5 to 12 mm and is made of 45# steel with heat treatment. The bottom end of the rotating block 1007 is connected to the top end of the rotating rod 801 through a rotating joint. When the vibratory motor 1006 operates, it drives the rotating block 1007 to rotate at high speed, converting the rotational motion of the rotating block 1007 into high-frequency reciprocating vibration of the rotating rod 801 along the axial direction. This design constitutes an important part of the pneumatic arch-breaking and vibration-assisted flow structure configured at the bottom of the silo. This is achieved through motor vibration, effectively preventing soda ash bridging and material blockage, and can break up material arches with a diameter ≤500mm, ensuring smooth discharge. A rubber vibration damping pad is installed between the support block 1005 and the top wall of the storage silo 1. The rubber vibration damping pad has a thickness of 15-30mm, a Shore hardness of 50-60, and a damping coefficient ≥0.3, which can reduce the transmission of vibration to the silo body, reduce equipment operating noise and structural fatigue.

[0027] In addition, to further enhance the automated cleaning function of the device, a second gear ring 12 is rotatably supported on the inner top of the storage chamber 4. The second gear ring has an outer diameter of 1.1–2.4 m, a module matching that of the gear 1003, and 75–155 teeth. The second gear ring 12 is coaxially sleeved on the outer side of the gear 1003 and meshes with it. 8–20 scraper rods 13 are fixedly connected in a circular array on the outer wall of the second gear ring 12. The scraper rods are 0.8–1.8 m long, 25–50 mm wide, and 6–10 mm thick, with their ends elastically fitting against the inner wall of the storage bin 1. When the gear 1003 drives the rotating rod 801 to rotate, it also drives the second gear ring 12 to rotate at a speed 0.9–1.1 times that of the rotating rod, thereby causing the scraper rods 13 to rotate along the inner wall of the storage bin 1, automatically cleaning the material adhering to the wall of the storage bin 1. The end of the scraper bar 13 is also equipped with a detachable wear-resistant scraper. The material is the same as that of the scraper bar scraper, and the service life is ≥8000 hours. It can be replaced regularly to ensure the cleaning effect and avoid scratching the inner wall of the bin.

[0028] In conjunction with the upwardly protruding partition 7 structure, a pusher rod 15 is fixedly connected to the bottom end of each scraper rod 13. The pusher rod is 400-800mm long, 40-70mm wide, and 8-12mm thick, and its bottom surface slides against the arc-shaped top surface of the partition 7. When the scraper rod 13 rotates with the second toothed ring 12, the pusher rod 15 slides synchronously on the surface of the partition 7 at a linear speed of 0.5-1.5m / s, pushing the raw material deposited in the central area of ​​the top surface of the partition 7 or accumulated on the slope outward along the arc-shaped slope until it is pushed into the automatic connecting pipe 14, thereby forcibly pushing the raw material into the discharge chamber 6 below. This design utilizes the principle of mechanical linkage, organically combining the bin wall cleaning action with the raw material distribution and feeding action, ensuring the uniformity and continuity of feeding into each discharge bin 5, with a feeding deviation of ≤±5% in each bin, avoiding overload or idling of a certain discharge bin 5 due to uneven feeding. The bottom surface of the push rod 15 is equipped with a low-friction wear-resistant slider. The low-friction wear-resistant slider is 5-8mm thick, made of ultra-high molecular weight polyethylene, and has a friction coefficient ≤0.15. This reduces sliding resistance and avoids scratching the arc-shaped guide surface of the partition 7, ensuring the smooth flow of raw materials.

[0029] The work process is as follows: First, the soda ash raw material is transported to the storage silo 1 through the feed pipe 2. When it is necessary to discharge the material, the drive assembly 10 is started. The servo motor 1004 drives all the processing parts 8 to start rotating through the rotating parts. At the same time, the vibration motor 1006 is started, which drives the processing parts 8 to perform high-frequency axial vibration.

[0030] The heating bar 806 on the processing unit 8 starts working to heat the raw material; at the same time, the rotating and vibrating wave-shaped heating bar 806 powerfully turns, disperses and cuts the raw material in the storage chamber 4, breaks up the agglomerates, and performs deep drying and dehumidification.

[0031] At the same time, the second toothed ring 12 is driven to rotate, the scraper rod 13 cleans the wall of the storage bin 1, and the bottom pusher rod 15 slides back and forth on the raised partition 7, forcibly pushing the raw material into the automatic connecting pipe 14 of the partition 7 and into the discharge chamber 6 below.

[0032] Inside the discharge chamber 6, the raw material moves toward the discharge port under the forced push of the screw 804. During this process, the agitator 9 rotates under the friction of the material, and the scraper rod 903 scrapes off the adhering material by sticking to the inner wall of the discharge chamber 6, ensuring smooth discharge.

[0033] The entire device achieves automated, convenient, and continuous material output. The flow rate can be controlled with a single button operation, eliminating the need for frequent manual operation. At the same time, the level gauge 11 monitors the inventory in real time, effectively reducing storage losses and labor costs, and greatly improving the stability of material supply to the production line.
