Description

Technical Field

[0001] This utility model relates to the field of metallurgical waste slag treatment technology, and in particular to a slag powder desiccant generating device. Background Technology

[0002] Slag powder is a high-fineness, high-activity powder obtained by water-quenched blast furnace slag through drying, grinding and other processes. It is a high-quality concrete admixture and cementitious material, and an important material for preparing high-performance concrete. In its production process, drying is a key step, and the drying effect directly affects the quality of slag powder and its subsequent applications. Therefore, efficient drying equipment is needed to ensure drying quality and efficiency.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing slag powder desiccant generating devices typically lack targeted agglomeration and impurity screening structures, making it difficult to effectively break up agglomerates and filter impurities in slag powder. This results in residual agglomerates and impurities in the slag powder, affecting the processing efficiency of subsequent drying and mixing stages. Furthermore, it is not convenient to comb and disperse the material during transportation, leading to raw material waste and uneven mixing of slag powder and auxiliary materials, thus affecting the consistency of desiccant product performance.

[0004] To address this, a slag powder desiccant generating device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a slag powder desiccant generating device that solves the problem that existing slag powder desiccant generating devices usually lack targeted agglomeration crushing and impurity screening structures, making it difficult to effectively disperse agglomerates and filter impurities in slag powder. This results in residual agglomerates and impurities in the slag powder, affecting the processing effect of subsequent drying and mixing stages. Furthermore, it is not convenient to sort and disperse the material during transportation, leading to raw material waste and uneven mixing of slag powder and auxiliary materials, which affects the consistency of desiccant product performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slag powder desiccant generating device, comprising a base, a mixing assembly being provided on the top of the base, a support base being fixedly connected to the outer side of the mixing assembly, a pretreatment assembly being provided on the top of the support base, the pretreatment assembly comprising a pretreatment frame being fixedly connected to the top of the support base, a guide inclined plate being fixedly connected to the top side of the pretreatment frame, an electric dispersing rod being fixedly connected inside the pretreatment frame, the electric dispersing rod being located at the bottom of the guide inclined plate, a vibration motor being fixedly connected to both sides of the pretreatment frame, a vibrating screen plate being provided at the output end of the vibration motor, a return spring rod being provided at the bottom of the vibrating screen plate, and a pneumatic drying assembly being provided at the bottom of the pretreatment frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application enables the dispersing, purification, and efficient drying of slag powder through a pretreatment component, improving the purity and dryness of the slag powder. Compared with the limitations of traditional slag powder treatment devices, which are difficult to disperse clumps, have poor screening and purification effects, and are prone to localized insufficient drying, this component breaks up clumps with an electric dispersing rod and screens impurities with a vibrating screen plate. Combined with the air-conveyed drying component, it achieves uniform drying, realizing the purification and thorough drying of slag powder. This solves the problem of poor moisture absorption performance of desiccant caused by impurities in slag powder and insufficient drying in traditional devices.

[0016] 2. This application enables the thorough mixing and stable conveying of slag powder and desiccant by means of a mixing component, thereby improving the mixing uniformity and conveying continuity of slag powder and desiccant. Compared with the design of traditional slag powder processing devices that are prone to residue during mixing and agglomeration during conveying, this component reduces the residue on the inner wall by means of a mixing rod and a scraper, and avoids agglomeration by means of a conveying auger. It can achieve uniform mixing of slag powder and auxiliary materials and agglomeration-free conveying function, which solves the problems of unstable desiccant performance and agglomeration during conveying that affect production efficiency due to uneven mixing in traditional devices.

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A slag powder desiccant generating device includes a base 1, a mixing assembly 4 on the top of the base 1, a support base 2 fixedly connected to the outside of the mixing assembly 4, a pretreatment assembly 5 on the top of the support base 2, the pretreatment assembly 5 including a pretreatment frame 51 fixedly connected to the top of the support base 2, a guide inclined plate 52 fixedly connected to the top side of the pretreatment frame 51, an electric dispersing rod 53 fixedly connected inside the pretreatment frame 51, the electric dispersing rod 53 being located at the bottom of the guide inclined plate 52, a vibration motor 54 fixedly connected to both sides of the pretreatment frame 51, a vibrating screen plate 55 provided at the output end of the vibration motor 54, a reset spring rod 56 provided at the bottom of the vibrating screen plate 55, and a pneumatic drying assembly 57 provided at the bottom of the pretreatment frame 51.

[0026] In this embodiment: the top cover 9 of the pretreatment frame 51 is opened by the handle 10, and the slag powder is poured into the pretreatment frame 51. The top cover 9 is closed to prevent the slag powder from splashing. The slag powder slides down the guide inclined plate 52 on the top side of the pretreatment frame 51. The guide inclined plate 52 guides the slag powder to flow downward in a concentrated manner to avoid accumulation. When the slag powder slides to the bottom, it contacts the electric dispersing rod 53. The electric dispersing rod 53 rotates to disperse the clumps of slag powder. The dispersed slag powder falls onto the vibrating screen plate 55. The vibration motors 54 on both sides of the pretreatment frame 51 are started. The vibration force drives the vibrating screen plate 55 to vibrate up and down. The reset spring rod 56 at the bottom of the vibrating screen plate 55 extends and retracts with the vibration, providing elastic support and maintaining the vibration frequency. Under the action of vibration, slag powder of the correct particle size falls through the screen holes, while impurities and undispersed clumps are intercepted, achieving screening. The screened slag powder enters the air-conveying drying component 57 to complete drying, and finally enters the subsequent processing stage.

[0027] Specifically, such as Figure 3 As shown, the mixing assembly 4 includes a conveying frame 41 fixedly connected to the top of the base 1, and a conveying motor 42 fixedly connected to the outside of the conveying frame 41.

[0028] Specifically, such as Figure 3 As shown, the output end of the conveyor motor 42 is fixedly connected to the conveyor auger 43, and the right side of the conveyor frame 41 is connected to the conveyor port 44.

[0029] Specifically, such as Figure 3 As shown, a mixing frame 45 is fixedly connected to the top of the conveying frame 41, a stirring support 46 is fixedly connected to the top of the mixing frame 45, a stirring motor 47 is fixedly connected to the top of the stirring support 46, and a stirring rod 48 is fixedly connected to the output end of the stirring motor 47.

[0030] In this embodiment: After the slag powder is dried, it falls into the mixing frame 45. At this time, the stirring motor 47 on the stirring support 46 at the top of the mixing frame 45 starts, and the power is transmitted to the stirring rod 48, which drives the stirring rod 48 to rotate and stir the slag powder. If auxiliary materials need to be added, they are also added at this stage. The stirring rod 48 mixes the slag powder and auxiliary materials thoroughly. During the stirring process, the auxiliary frame 6 at the bottom of the stirring support 46 remains stable. The compression spring 7 in the auxiliary frame 6 pushes the scraper 8 to adhere to the inner wall of the mixing frame 45, scraping off the attached slag powder to avoid residue. The mixed slag powder enters the conveying frame 41 below. The conveying motor 42 on the outside of the conveying frame 41 starts, and the power is transmitted to the conveying auger 43, which drives the conveying auger 43 to rotate. The slag powder is pushed forward through the spiral structure. During the pushing process, the slag powder is further combed to avoid agglomeration. Finally, the slag powder is sent out through the conveying port 44 on the right side of the conveying frame 41, completing the mixing and conveying.

[0031] Specifically, such as Figure 5 As shown, an auxiliary frame 6 is fixedly connected to the bottom of the stirring support 46, a compression spring 7 is fixedly connected inside the auxiliary frame 6, and a scraper 8 is fixedly connected to the outside of the compression spring 7.

[0032] Specifically, such as Figure 4 As shown, the air-driven drying assembly 57 includes a drying chamber 571 fixedly connected inside the pretreatment frame 51, a fan 572 fixedly connected inside the drying chamber 571, a heating pipe 573 provided inside the fan 572, an airflow guide plate 574 fixedly connected inside the drying chamber 571, and a dust filter plate 575 fixedly connected outside the drying chamber 571.

[0033] In this embodiment: by setting up an auxiliary frame 6, a compression spring 7, and a scraper 8, when the stirring motor 47 drives the stirring rod 48 to rotate and stir the slag powder within the mixing frame 45, the compression spring 7 inside the auxiliary frame 6 is in a natural extension and contraction state, and the scraper 8 on its outer side will closely adhere to the inner wall of the mixing frame 45. When the slag powder adheres to the inner wall of the mixing frame 45 due to its stickiness during stirring, the compression spring 7 will continuously push the scraper 8 with its own elasticity, ensuring that the scraper 8 is always in contact with the inner wall. While the stirring rod 48 rotates, the scraper 8 will simultaneously scrape off the slag powder adhering to the inner wall, avoiding the waste of raw materials caused by slag powder residue, and also preventing the residual slag powder from clumping due to long-term retention, thus affecting the subsequent mixing effect, thereby ensuring the uniformity of the mixing of slag powder and auxiliary materials. By setting up a drying chamber 571, a fan 572, a heating pipe 573, an airflow guide plate 574, and a dust filter plate 575, after the sieved slag powder enters the drying chamber 571 at the bottom of the pretreatment frame 51, the fan 572 inside the drying chamber 571 starts to operate. The airflow generated first flows through the inner heating pipe 573. After the heating pipe 573 is energized and heats up, it heats the airflow into hot air. When the hot air flows in the drying chamber 571, it is guided by the inner airflow guide plate 574. The airflow guide plate 574, through a preset tilt angle, makes the hot air form a circulating airflow in the drying chamber 571, so that the falling slag powder can come into contact with the hot air in all directions, avoiding the incomplete drying of some slag powder due to lack of contact with the hot air, and finally achieving efficient and clean drying of slag powder.

[0034] Specifically, such as Figure 1 As shown, a top cover 9 is rotatably connected to the top of the pretreatment frame 51, and a handle 10 is fixedly connected to the outside of the top cover 9.

[0035] Specifically, such as Figure 1 As shown, a control panel 3 is provided on the outside of the conveyor frame 41.

[0036] In this embodiment: By setting a top cover 9 and a handle 10, before using the device, the operator holds the handle 10 on the outside of the top cover 9 of the pretreatment frame 51 and rotates the top cover 9 upward to open it. At this time, the feed port of the pretreatment frame 51 is opened, making it easy to pour the slag powder to be treated into the pretreatment frame 51. After pouring in the slag powder, the top cover 9 is rotated in the opposite direction to close it by using the handle 10. The top cover 9 can form a seal on the pretreatment frame 51, preventing the slag powder from splashing out of the pretreatment frame 51 due to vibration or airflow during the subsequent dispersing and screening process, thus reducing raw material waste. By setting a control panel 3, the operator can adjust the various components of the device through the control panel 3 on the outside of the conveying frame 41 throughout the entire slag powder desiccant preparation process. The operator can set parameters such as the rotation speed of the electric dispersing rod 53, the vibration frequency of the vibration motor 54, the heating temperature of the heating tube 573, the wind speed of the fan 572, the stirring speed of the stirring motor 47, and the conveying speed of the conveying motor 42, thereby ensuring the stable and efficient operation of the device and ensuring the quality of the slag powder desiccant preparation.

[0037] Working Principle: In using this slag powder desiccant generator, firstly, open the top cover 9 of the pretreatment frame 51 using handle 10, and pour the slag powder to be processed into the pretreatment frame 51. After entering, the slag powder will slide downwards along the guide inclined plate 52 on the top side of the pretreatment frame 51. The guide inclined plate 52 guides the slag powder to flow downwards to the processing area, preventing the slag powder from accumulating inside the pretreatment frame 51. When the slag powder slides to the bottom of the guide inclined plate 52, it will contact the electric dispersing rod 53. The electric dispersing rod 53 is in a rotating state at this time, and its rotation will initially disperse the falling slag powder, breaking up any possible clumps, preparing for subsequent screening and drying. After initial dispersal, the slag powder... The powder falls onto the vibrating screen plate 55 below. At this time, the vibrating motors 54 on both sides of the pretreatment frame 51 start working. The vibration force generated by the vibrating motors 54 is transmitted to the vibrating screen plate 55, causing the vibrating screen plate 55 to vibrate up and down. The return spring rod 56 at the bottom of the vibrating screen plate 55 will extend and retract with the vibration of the vibrating screen plate 55. On the one hand, it provides elastic support for the vibrating screen plate 55 and reduces rigid impact during vibration. On the other hand, it helps the vibrating screen plate 55 maintain a stable vibration frequency through its own reset action. Under the vibration of the vibrating screen plate 55, fine powder with the required particle size in the slag powder will fall through the screen holes, while larger impurities or undissolved clumps will be intercepted on the vibrating screen plate 55, realizing the screening and purification of the slag powder and ensuring the subsequent processing of the slag powder. The slag powder, after screening, enters the bottom of the pretreatment frame 51, where the drying chamber 571 serves as the main drying space. Inside, the blower 572 operates, and the airflow generated by the blower 572 first passes through the inner heating pipe 573. The heating pipe 573, when energized, heats the airflow, forming hot air. As the hot air flows within the drying chamber 571, it is guided by the inner airflow guide plate 574. The airflow guide plate 574, through a specific tilt angle and distribution, creates a circulating airflow within the drying chamber 571, ensuring that the hot air can evenly contact the falling slag powder and avoid incomplete drying in certain areas. During its descent, the slag powder fully contacts the hot air, and the moisture is carried away by the hot air, achieving drying. Meanwhile, the dust filter plate on the outside of the drying chamber 571... The airflow is filtered at 575. The dried slag powder falls from the pretreatment component 5 into the mixing frame 45. At this time, the stirring motor 47 on the top stirring support 46 of the mixing frame 45 starts, transmitting power to the stirring rod 48 below, causing it to rotate within the mixing frame 45. During rotation, the stirring rod 48 stirs the slag powder falling into the mixing frame 45. Then, other desiccant additives are added, and the stirring rod 48 thoroughly mixes the slag powder with the additives. Simultaneously, the auxiliary frame 6 at the bottom of the stirring support 46 remains stable during the stirring process. The compression spring 7 inside the auxiliary frame 6 is in a naturally extended / retracted state, and the scraper 8 on its outer side adheres to the inner wall of the mixing frame 45. While the stirring rod 48 is stirring...A small amount of slag powder may adhere to the inner wall of the mixing frame 45. The compression spring 7 will push the scraper 8 through its own elasticity, ensuring that the scraper 8 is always in close contact with the inner wall. During the mixing process, the slag powder adhering to the inner wall is scraped off simultaneously, avoiding raw material residue and waste, and ensuring uniform mixing. After mixing, the slag powder will enter the lower conveying frame 41. Then, the conveying motor 42 on the outside of the conveying frame 41 will start, and the power of the conveying motor 42 will be transmitted to the conveying auger 43 at the output end. The conveying auger 43 will then rotate within the conveying frame 41, and the conveying auger 43 will push the slag powder forward through the spiral structure. During the pushing process, the continuity of conveying is ensured, and the slag powder is further combed to prevent clumping. Finally, the slag powder will be discharged through the conveying port 44 on the right side of the conveying frame 41, completing the entire preparation process of the slag powder desiccant.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
