[0018] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] It should be noted that slag powder, also known as granulated blast furnace slag powder, is a powder material obtained by quenching, drying, and grinding blast furnace slag produced during the ironmaking process. It is an inevitable byproduct of the blast furnace ironmaking process, but with proper processing, it can be transformed into a high-quality building material. The main chemical components of slag powder are silicates and oxides, such as dicalcium silicate, tricalcium silicate, and tricalcium aluminate. These components give slag powder a high density and good compressive strength, enabling it to enhance and improve the performance of concrete. Furthermore, slag powder exhibits a certain degree of pozzolanic activity, allowing it to undergo a secondary reaction with cement hydration products during the cement hydration process, further enhancing the strength and durability of concrete. Application Value in Concrete: Slag powder, as a high-quality concrete admixture, enjoys widespread market demand. It can partially replace cement, not only reducing concrete costs but also improving its workability, strength, and durability. For example, adding an appropriate amount of slag powder can enhance concrete's resistance to sulfate attack, carbonation, and impermeability, extending the service life of concrete structures. Consequently, slag powder is widely used in infrastructure construction, including buildings, roads, and bridges. Function and Importance of Storage Tanks: Slag powder storage tanks are specialized equipment for storing slag powder, designed and engineered to meet industrial production and storage needs. They are primarily used to store ground slag, fly ash, cement, and other materials, providing crucial support for the production, transportation, and use of slag powder. An efficient and reliable storage tank ensures stable slag powder quality during storage, facilitates loading and unloading operations, and improves production efficiency. Limitations of Existing Storage Tanks: While existing slag powder storage tanks meet storage needs to a certain extent, some practical issues remain. For example, the inherent viscosity and granularity of slag powder make it easy for particles to squeeze and stick together during discharge, leading to blockage in the discharge channel. This blockage not only affects reclaiming efficiency but can also damage equipment and increase maintenance costs.

[0020] Urgent need for improved storage tanks: The increasing application of slag powder in the construction material sector has placed higher demands on the performance and functionality of slag powder storage tanks. Consequently, there is an urgent need for new storage tanks that can effectively resolve slag powder blockage issues, improve discharge efficiency, and precisely control discharge flow. This will not only help improve slag powder production efficiency and quality, but also reduce operating costs for businesses, promoting the sustainable development of the slag powder industry.

[0021] The embodiment of the present invention provides a storage tank for slag powder production and processing, such as Figure 1-10As shown, the storage tank for slag powder production and processing includes: a tank rack 1; a tank body 2 fixed on the tank rack 1 for storing slag powder; a tank cover 3, arranged on the top of the tank body 2, for closing the tank body 2; a sealing cone 4 arranged in the discharge port at the bottom of the tank body 2; a discharge system arranged at the bottom of the tank body 2 and cooperating with the sealing cone 4, the discharge system including at least one discharge barrel 7 and a rotatable guide assembly mounted on the sealing cone 4; a drive system including a motor 15 and a transmission mechanism for driving the guide assembly to rotate.

[0022] In this embodiment, when the storage tank for slag powder production and processing is in use, slag powder is added to the tank body 2 for storage. When the slag powder needs to be taken out, the sealing cone 4 is adjusted to move downward to leak out of the discharge port, and then the motor 15 in the drive system is started, and the motor 15 drives the guide component to rotate through the transmission mechanism. Under the rotation of the guide component, the slag powder can move smoothly downward in the discharge barrel 7 and finally be discharged from the discharge port at the bottom of the tank body 2. The entire discharge process is completed by the discharge system and the drive system in coordination. The flow of slag powder is guided by the rotation of the guide component, which effectively avoids the situation where the slag powder is squeezed and adhered to each other due to its own viscosity and particle characteristics during discharge, thereby blocking the discharge channel.

[0023] The storage tank for slag powder production and processing of the present invention can continuously and stably discharge slag powder from the discharge barrel 7 through the rotation of the guide assembly, greatly reducing the interruption of material collection due to blockage and greatly improving the material collection speed; In the present invention, the tank body 2 adopts a cylindrical structure. This shape has good symmetry and stability, which can ensure relatively uniform distribution of slag powder within the tank, reducing localized accumulation or dead corners caused by irregular shapes. The tank body 2 is manufactured from high-strength, corrosion-resistant steel, such as Q345 steel, which has excellent comprehensive mechanical properties and corrosion resistance, effectively resisting erosion by slag powder. Furthermore, the inner and outer walls of the tank body 2 are treated with anti-corrosion treatments, such as hot-dip galvanizing and spraying of anti-corrosion coatings, to further enhance the tank's corrosion resistance and extend the service life of the equipment. The sealing cone 4 is a key component, installed within the discharge port at the bottom of the tank 2, controlling its opening and closing. Its shape matches the discharge port, tightly sealing it and preventing slag powder from leaking during storage. When discharge is required, the sealing cone 4 moves downward, out of the discharge port, allowing the slag powder to be discharged smoothly. The design of the discharge barrel 7 must take into account the flow characteristics and discharge rate of the slag powder. Its inner wall should be smooth and inclined at a certain angle to ensure smooth downward movement of the slag powder. The rotation of the guide assembly further guides the flow of the slag powder, preventing accumulation or blockage within the discharge barrel 7. Furthermore, a regulating valve can be installed at the outlet of the discharge barrel 7 to control the discharge rate and flow rate of the slag powder to meet different production requirements.

[0024] In a further preferred embodiment of the present invention, the discharge system also includes a material guiding mechanism, which includes: an assembly cylinder 5 fixedly installed on the bottom of the tank body 2; a connecting cylinder 22 that is slidably installed on the assembly cylinder 5 and can be raised and lowered, for guiding slag powder; a material guiding plate 6 fixedly connected to the bottom of the connecting cylinder 22, and the discharge port of the material guiding plate 6 is connected to the corresponding discharge cylinder 7.

[0025] In this embodiment, the discharge system of the slag powder production and processing storage tank utilizes a guide mechanism to achieve smooth discharge of slag powder. During operation, the slag powder enters the assembly barrel 5 from the discharge port at the bottom of the tank body 2, then falls into the guide plate 6 via the connecting barrel 22. Guided by the conical surface of the guide plate 6, the slag powder is smoothly guided to the corresponding discharge barrel 7, from which it is ultimately discharged. The guide mechanism and the discharge system work closely together to ensure that the slag powder can be efficiently discharged from the bottom of the tank body 2. The assembly cylinder 5 and the liftable connecting cylinder 22 provide a stable transmission channel for the slag powder, and the conical surface design of the guide plate 6 effectively guides the slag powder into the discharge cylinder 7, reducing the accumulation and blockage of slag powder during the discharging process; improving the discharging speed of the slag powder and reducing the risk of equipment failure caused by poor discharging. When discharging is required, the output rod of the electric hydraulic rod 21 extends, driving the connecting cylinder 22 to descend, so that the slag powder can smoothly enter the guide plate 6; when discharging is completed, the output rod of the electric hydraulic rod 21 retracts, the connecting cylinder 22 rises, and the sealing cone 4 blocks the discharge port to prevent slag powder from leaking.

[0026] In a further preferred embodiment of the present invention, the guiding assembly includes: a mounting shell 8 fixed to the bottom of the sealing cone 4; a first auger 9 on the mounting shell 8 through a bearing, one end of the first auger 9 extending into the corresponding discharge barrel 7; a second auger 10 assembled on the sealing cone 4 through a bearing, the bottom end of the second auger 10 extending into the mounting shell 8; a first bevel tooth 11 fixed on the second auger 10; and a second bevel tooth 12 fixed on the first auger 9 and engaged with the first bevel tooth 11.

[0027] In this embodiment, the guide assembly achieves smooth conveyance of slag powder. When in use, the motor 15 is started and drives the second auger 10 to rotate through the transmission mechanism. As the sealing cone 4 descends to open the discharge port, the second auger 10 also descends and passes through the discharge port. The first bevel gear 11 is fixed to the second auger 10, and the first bevel gear 11 engages with the second bevel gear 12, which enables the first auger 9 to rotate accordingly. This rotation can input the slag powder into the discharge barrel 7, thereby achieving smooth discharge of the slag powder. Through the coordinated rotation and transportation of the first auger 9 and the second auger 10, the accumulation and blockage of the slag powder during the discharging process are reduced, the discharging speed of the slag powder is increased, and the continuity of the discharging is ensured.

[0028] In a further preferred embodiment of the present invention, the transmission mechanism includes: a first rotating rod 13 assembled on the tank cover 3 through a bearing; a third bevel gear 16 fixed on the first rotating rod 13 and the output shaft of the motor 15 and engaged with each other; a mounting tube 17 fixed to the bottom end of the first rotating rod 13, a slide rod 19 being slidably installed in the mounting tube 17, and the bottom end of the slide rod 19 being fixedly connected to the shaft of the second auger 10; a spline seat 18 fixed in the mounting tube 17; and a spline block 20 fixed on the slide rod 19.

[0029] In this embodiment, when the motor 15 begins operating, its output shaft rotates the third bevel gear 16. Because the third bevel gear 16 engages with the bevel gears on the first rotating rod 13, the first rotating rod 13 rotates accordingly. The bottom end of the first rotating rod 13 is connected to a mounting tube 17, which contains a slide rod 19. The bottom end of the slide rod 19 is connected to the shaft of the second auger 10. When the sealing cone 4 descends, the slide rod 19 descends with it, and the spline block 20 on the slide rod 19 engages the spline seat 18 in the mounting tube 17. As the first rotating rod 13 rotates, the spline seat 18 and the spline block 20 engage, causing the slide rod 19 to rotate accordingly, thereby driving the second auger 10. This allows the power from the motor 15 to be smoothly transmitted to the second auger 10, enabling it to function properly and helping the slag powder to be discharged smoothly from the discharge barrel 7.

[0030] In a further preferred embodiment of the present invention, an electric hydraulic rod 21 is symmetrically fixed on the assembly cylinder 5, and the output rod of the electric hydraulic rod 21 is fixedly connected to the guide plate 6 for regulating the lifting thereof.

[0031] In this embodiment, electro-hydraulic rods 21 are symmetrically fixed to the assembly barrel 5 of the slag powder production and processing storage tank. The output rods of these electro-hydraulic rods 21 are fixedly connected to the material guide tray 6. When discharge is required, the output rods of the electro-hydraulic rods 21 extend, driving the material guide tray 6 downward. Because the material guide tray 6 is connected to the connecting barrel 22, the connecting barrel 22 slides downward along the chute on the assembly barrel 5. Simultaneously, the sealing cone 4 descends, opening the discharge port and preparing for subsequent slag powder discharge.

[0032] The lifting and lowering of the material guide plate 6 is regulated by the electric hydraulic rod 21, so that the opening and closing of the discharge port are more convenient.

[0033] In a further preferred embodiment of the present invention, a feeding pipe 45 is fixedly connected to the top of the tank cover 3 , a sealing cover is provided on the feeding pipe 45 , and a ladder 44 is provided on the tank rack 1 .

[0034] In this embodiment, a feeding pipe 45 is fixedly connected to the top of the tank lid 3 of the slag powder production and processing storage tank. The feeding pipe 45 is equipped with a sealing cap, and a ladder 44 is also provided on the tank stand 1. When adding slag powder to the tank body 2, a worker can climb up the ladder 44 to the tank stand 1, open the sealing cap on the feeding pipe 45, and then use the injection equipment to add the slag powder through the feeding pipe 45 into the tank body 2. Similarly, when equipment inspection or maintenance is required, workers can also easily reach the tank stand 1 via the ladder 44 to perform operations. The ladder 44 is provided to enable the staff to reach the height of the tank rack 1, which is convenient for adding materials, overhauling, maintenance and replacing components.

[0035] In a further preferred embodiment of the present invention, a plurality of air injection pipes 24 are fixedly connected to the first rotating rod 13 , a first scraper 25 is fixed to the air injection pipe 24 , and a second scraper 26 is fixed to the bottom end of the second auger 10 .

[0036] In this embodiment, a plurality of air jets 24 are fixedly connected to the first rotating rod 13 of the storage tank for slag powder production and processing, and these air jets 24 can spray hot air. At the same time, a first scraper 25 is fixed to the air jet 24, and a second scraper 26 is fixed to the bottom end of the second auger 10. When the equipment is running, the air jet 24 will spray hot air, and the first scraper 25 and the second scraper 26 will rotate with the rotation of the first rotating rod 13 and the second auger 10. During the rotation, the first scraper 25 and the second scraper 26 can scrape off the slag powder residues on the inner wall of the tank body 2 and the discharge barrel 7, reducing the accumulation of materials. At the same time, the rotation of the second scraper 26, in conjunction with the hot air sprayed from the air jet 24, can also stir the slag powder in the tank body 2; The hot air ejected from the air jet 24 effectively removes moisture from the slag powder, preventing it from clumping due to moisture and affecting subsequent processing. The scraping action of the first and second scrapers 25, 26 reduces the amount of slag powder remaining on the inner wall of the tank 2 and within the discharge barrel 7. Furthermore, the rotation of the second scraper 26, combined with the hot air from the air jet 24, stirs the slag powder, ensuring a more even distribution within the tank 2 and facilitating subsequent discharge.

[0037] In a further preferred embodiment of the present invention, an air passage 23 is provided on the first rotating rod 13 , the air passage 23 is connected to the air injection pipe 24 , a rotary joint 31 is provided at the air inlet end of the air passage 23 , and a plurality of inclined air injection holes are provided on the air injection pipe 24 .

[0038] In this embodiment, an air passage 23 is provided on the first rotating rod 13 of the slag powder production and processing storage tank. This air passage 23 is connected to an air injection pipe 24. A rotary joint 31 is installed at the air inlet end of the air passage 23, so that the air passage 23 can also normally transport gas when the first rotating rod 13 rotates. The air injection pipe 24 is provided with multiple inclined air injection holes. When the gas enters the air injection pipe 24 through the air passage 23, it is ejected from these inclined air injection holes. This ejected gas can dehumidify the slag powder in the tank body 2. The design of the air passage 23 and the air blast pipe 24 allows gas to effectively enter the tank body 2 and function. The rotary joint 31 ensures stable gas delivery even while the first rotating rod 13 is rotating, ensuring continuous air blasting. The angled air holes in the air blast pipe 24 allow gas to be ejected at a specific angle, which not only improves mixing of the slag powder but also increases the contact area between the gas and the slag powder, enhancing dehumidification. The hot air ejected from the air blast pipe 24 acts as a drying agent, reducing humidity and lowering the viscosity between slag powder particles. The rotation of the first scraper 25 and the second scraper 26 allows for easier scraping of residual slag powder from the inner walls of the tank body 2 and the discharge barrel 7. Furthermore, the rotation of the second scraper 26, combined with the hot air from the air blast pipe 24, stirs the slag powder, ensuring a more even distribution within the tank body 2 and facilitating subsequent discharge. The air blast pipe 24 is equipped with multiple angled air holes. The direction and volume of air ejected from the air blast pipe 24 can be adjusted based on the characteristics of the slag powder and the shape of the tank body 2 to achieve optimal dehumidification and stirring. For example, the inclination angle of the air jet hole can be designed to be 30°-60° with the inner wall of the tank body 2 , and the air jet volume can be controlled by adjusting the air intake pressure or flow rate of the air passage 23 .

[0039] In a further preferred embodiment of the present invention, an exhaust pipe 32 is fixedly installed on the top of the tank cover 3, and an air outlet pipe 33 is fixedly connected to the exhaust pipe 32. An adjustable sealing plate 34 is provided in the air outlet pipe 33.

[0040] In this embodiment, the design of the exhaust pipe 32 and the outlet pipe 33 provides a discharge channel for the gas in the tank body 2, which helps to maintain the air pressure balance in the tank body 2. The adjustable sealing plate 34 increases the flexibility of the exhaust process; The design of the exhaust pipe 32, outlet pipe 33, and adjustable sealing plate 34 allows for efficient and flexible exhaust and control of gas within the tank 2. The diameter and length of the exhaust pipe 32 and outlet pipe 33 should be appropriately designed based on the size and internal pressure of the tank 2 to ensure smooth gas discharge. Furthermore, a muffler can be installed at the outlet of the outlet pipe 33 to reduce noise generated during gas discharge and minimize environmental impact.

[0041] In a further preferred embodiment of the present invention, a mounting frame 14 for assembling the motor 15 is fixedly mounted on the top of the tank rack 1 , and a protective shell is provided on the mounting frame 14 for shielding the motor 15 .

[0042] In this embodiment, a mounting bracket 14 for assembling a motor 15 is fixedly mounted on the top of the tank frame 1 of the slag powder production and processing storage tank. A protective housing is also provided on the mounting bracket 14. This housing primarily shields the motor 15. This housing protects the motor 15 from accidental contact and injury during operation, thus enhancing safety.

[0043] In order to further improve the use effect of this device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, the mounting frame 14 is provided with an air supply mechanism for supplying hot air, and the air supply mechanism includes: an electric heating box 27 fixed on the mounting frame 14, an electric heating tube is provided in the electric heating box 27, a spline tube 28 assembled in the electric heating box 27 through a bearing, and a fan blade 29 is fixedly mounted on the spline tube 28; a connecting pipe 30 fixedly connected to the electric heating box 27, and the air outlet end of the connecting pipe 30 is connected to the rotary joint 31; an electric telescopic rod 36 fixed on the outer wall of the electric heating box 27, and a mounting plate 37 is fixedly mounted on the electric telescopic rod 36; a connecting frame 43 is fixedly mounted on the mounting plate 37, and the connecting frame 43 is fixedly connected to the sealing plate 34; a spline rod 38 assembled on the mounting plate 37 through a bearing, and one end of the spline rod 38 is inserted into the spline tube 28; a fourth bevel tooth 39 fixed on the spline rod 38, and the fourth bevel tooth 39 can engage with the third bevel tooth 16.

[0044] The electric heating box 27 is the core component of the air supply mechanism. It houses a heating tube that heats the air entering the box. The temperature of the heating tube is controlled by a thermostat. The outer shell of the electric heating box 27 is made of a thermally insulating material, which effectively prevents heat loss and improves heating efficiency.

[0045] In this embodiment, before stirring the slag powder in the tank body 2, the electric telescopic rod 36 can be started. The extension of its output rod will drive the mounting plate 37 to move forward, and the spline rod 38 will move accordingly, and the fourth bevel gear 39 will engage with the corresponding third bevel gear 16. In this way, when the motor 15 is started, the third bevel gear 16 can drive the fourth bevel gear 39 to rotate, and then drive the spline rod 38 and the spline tube 28 to rotate, so that the fan blades 29 rotate. The hot air in the electric heating box 27 is drawn out by the rotating fan blades 29, enters the air duct 23 through the connecting pipe 30 and the rotary joint 31, and is finally ejected from the air injection pipe 24. At the same time, the movement of the mounting plate 37 will also drive the connecting frame 43 to move, and the sealing plate 34 will slide out of the air outlet pipe 33, preparing for exhaust during subsequent dehumidification. The design of the air supply mechanism allows the storage tank to effectively preheat and dehumidify the slag powder in the tank body 2 before stirring the slag powder. The telescopic movement of the electric telescopic rod 36 can achieve the meshing of the fourth bevel gear 39 with the third bevel gear 16, thereby utilizing the power of the motor 15 to drive the fan blades 29 to rotate and transport the hot gas.

[0046] In another embodiment of the present invention, a dust filtering mechanism is provided on the exhaust pipe 32, and the dust filtering mechanism includes: a filter cover 35 fixed on the air inlet end of the exhaust pipe 32; a second rotating rod 40 assembled on the filter cover 35 through a sealed bearing, a cleaning brush 42 is fixed on the bottom end of the second rotating rod 40 for cleaning the filter cover 35; and a fifth bevel tooth 41 fixed on the second rotating rod 40 and meshing with the spline tube 28.

[0047] In this embodiment, during the dehumidification process, the rotation of the spline tube 28 drives the fifth bevel gear 41, which in turn drives the second rotating rod 40 and the cleaning brush 42. During rotation, the cleaning brush 42 continuously cleans the filter cover 35, preventing it from being clogged by dust and slag powder, ensuring smooth exhaust from the exhaust pipe 32. Furthermore, the filter cover 35 blocks slag powder from escaping from the exhaust pipe 32, preventing it from polluting the environment.

[0048] The dust filter design solves the problem of dust and slag powder clogging that may occur during the exhaust process. The cleaning brush 42 continuously cleans the filter cover 35 to prevent clogging, thereby ensuring the exhaust efficiency of the exhaust pipe 32. At the same time, the filter cover 35 prevents slag powder from escaping from the exhaust pipe 32 and polluting the environment.

[0049] To sum up, compared with the relevant technology, the slag powder flow is guided by the rotation of the guide component, and the conical guidance of the guide mechanism is used to avoid the slag powder from being squeezed and adhered due to its viscosity and particle characteristics, reduce blockage, and improve the material collection speed; the transmission mechanism realizes power transmission through the spline structure, and cooperates with the electric hydraulic rod 21 to regulate the lifting of the guide plate 6 to realize convenient opening and closing of the discharge port; the air jet 24 sprays hot air for dehumidification, and the first scraper 25 and the second scraper 26 scrape off the residue and stir the slag powder to prevent agglomeration.

[0050] In the several embodiments provided in this application, it should be understood that the disclosed device can be implemented in other ways.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the invention.
