Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water quenching slag processing, and particularly relates to a system and method for producing admixture by using stainless steel water quenching slag. BACKGROUND

[0002] The mineral admixture is a powder material with a specified fineness and one or more oxides of silicon, aluminum, calcium, etc. as main components, which can improve the performance of concrete when mixed into concrete, and can be divided into active mineral admixture and inert mineral admixture. The stainless steel water quenching slag is a glassy granular material formed after being treated by a water quenching rapid cooling process in the process of stainless steel smelting. The main mineral components of the water quenching slag are C3S and C2S, and the performance reaches the first level technical requirements of the steel slag powder in the 'Technical Specification for Application of Mineral Admixtures' and 'Steel Slag Powder for Cement and Concrete', and the reuse effect is achieved in the preparation of the admixture.

[0003] In the production of the admixture by using the water quenching slag, a crushing tower is usually used for crushing operation and synchronous drying treatment. The dust after drying is sucked into a dust collector from the upper end of the crushing tower, and then is conveyed to a storage tower for storage through a transmission mechanism. Although this process realizes the integration of crushing and drying, and improves the production efficiency to a certain extent, in the drying process, the synchronous direct suction of the powder will inevitably extract part of the water vapor generated during drying. Since the part of the water vapor contacts the powder, the powder will absorb the water vapor again, and finally the drying is not complete, which affects the quality of the subsequent water quenching slag admixture.

[0004] In view of the above technical defects, the present application provides a solution. First, the high-quality powder is prepared by multi-stage fine crushing, and then the powder is subjected to multi-stage uniform drying treatment, and the powder is intercepted to separate the water vapor, so as to improve the drying efficiency and quality.

[0008] Preferably, a material scattering disc is rotatably connected to the top of the crushing tower body, a scattering port is formed in the bottom of the material scattering disc on the side of the rolling pressure wheel, and a feeding hopper is installed on the top of the crushing tower body and communicated with the material scattering disc.

[0009] Preferably, a rotating rod is rotatably connected to the top of the crushing tower body and fixedly connected with the grinding rotating table and the material scattering disc, a motor is installed to drive the rotation of the rotating rod, a supporting rod is fixedly connected to the rotating rod and rotatable with the corresponding rolling pressure wheel, and a discharging scraper is in sliding contact with the top of the material supporting disc.

[0010] Preferably, a rotating shaft is rotatably connected to the inside of the rolling pressure wheel and extends to the outside of the rolling pressure wheel, an eccentric block is fixedly connected to the rotating shaft, a gear is fixedly connected to the end of the rotating shaft, and a gear ring is fixedly connected to the inner wall of the crushing tower body and engaged with the gear.

[0011] Preferably, the bottom of the rotating rod is fixedly connected with the plurality of drying discs through a work-type frame, the plurality of discharge ports are distributed in a spiral shape, a temporary storage hopper is fixedly connected to the inner wall of the crushing tower body between adjacent drying discs, a scraping plate is fixedly connected to the top of each drying disc, and the temporary storage hopper is in sliding contact with the bottom of the corresponding drying disc and the scraping plate is in sliding contact with the top of the corresponding drying disc.

[0012] Preferably, a cam disc is arranged on the top of the drying disc, the cam disc is fixedly connected with the corresponding drying disc and the work-type frame, a metal filter screen is arranged between the cam disc and the drying disc below the cam disc, a rotary joint is rotatably installed on the top of the work-type frame and communicated with the middle cavity of the drying disc, and an air outlet pipe is communicated with the rotary joint and extends to the outside of the crushing tower body.

[0013] Preferably, a spiral pipe is installed on the outer wall of the crushing tower body and communicated with one end of the air outlet pipe through a liquid collecting tank, and an air inlet is formed in the bottom of one side of the crushing tower body and embedded with a filter screen.

[0014] Preferably, a movable plate is fixedly connected to the scraping plate through a spring and in sliding connection with the scraping plate, a guide rod is arranged on the movable plate and in sliding contact with the cam disc, and a cleaning brush is arranged on the movable plate.

[0015] The application further provides a method for producing a blending material by using stainless steel water quenched slag, which comprises the following steps:

[0016] Bulk material handling: The bulk material tray rotates synchronously with the rolling wheel, and the water-quenched slag is piled up in a ring on the material tray;

[0017] Multi-stage refining process: The crushing wheel rotates in conjunction with the material support plate to initially crush the water-quenched slag, and the crushing effect is enhanced by the vibration of the crushing wheel caused by the rotation of the eccentric block. Then, the crushed material is guided to fall between the grinding turntable and the grinding seat by the tilting of the feeding scraper for secondary grinding.

[0018] Flat-lay high-efficiency drying method: The powder falls in a ring onto the top drying tray for primary drying. The drying tray rotates and, combined with the scraper on top, scrapes the primary dried material into the temporary storage hopper. The material is then fed in a linear fashion to the next drying tray for secondary even drying. Finally, it is combined with multiple drying trays below for multi-stage drying.

[0019] Thermal energy auxiliary utilization stage: Through the spiral tube and the external fan, the water vapor generated by the drying of powder in the crushing tower is extracted to prevent powder overflow. During the discharge of water vapor, its internal heat is transferred to the crushing tower through the spiral tube to assist in the preheating of water-quenched slag during the crushing process.

[0020] The beneficial effects of this invention are as follows:

[0021] (1) The present invention is to achieve multi-stage crushing of stainless steel water-quenched slag by setting up a material support plate and a crushing wheel, as well as a grinding turntable and a grinding seat. During the crushing process, the rotation of the crushing wheel, combined with the toothed ring and gear, causes the eccentric block inside the crushing wheel to rotate, which drives the crushing wheel to achieve vibratory circumferential rotation, which can further assist and enhance the crushing effect of the crushing wheel on the water-quenched slag.

[0022] Then, multiple drying trays combined with scrapers are used to achieve multi-stage drying of water-quenched slag powder. During the process of the powder falling step by step, the powder is distributed linearly through a temporary hopper. Combined with the rotation of the drying trays, the powder is evenly distributed on the drying trays, thereby achieving uniform drying and improving drying efficiency.

[0023] (2) The present invention also addresses the issue that during the drying of water-quenched slag powder, the water vapor generated is extracted and discharged through the central cavity formed by multiple drying trays, combined with the exhaust pipe and spiral tube, to avoid the problem of secondary moisture in the dried powder; and during the discharge process, the powder flowing in the traction is blocked and overflow is prevented by the metal filter screen, so as to achieve comprehensive collection and treatment of the powder to prevent escape, and the metal filter screen and cam plate are rotated by the drying trays to achieve efficient cleaning of the metal filter screen by the cleaning brush, so as to avoid the problem of the metal filter screen being blocked, which would make it difficult for water vapor to be discharged efficiently and thus result in poor drying effect;

[0024] In addition, when water vapor is discharged through the spiral tube, the internal heat is transferred to the pulverizing tower body through the spiral tube, which can assist in preheating the water-quenched slag during the pulverizing process and further improve the efficiency of the overall drying of the powder.

[0042] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1: Please refer to Figures 1-11 As shown, the current drying process often employs simultaneous direct extraction of powder, which simultaneously extracts some of the water vapor generated during drying. This causes the powder to reabsorb water vapor, resulting in incomplete drying. The following solutions can be used to address this issue:

[0044] This embodiment of a system for producing admixtures using stainless steel water-quenched slag includes a crushing tower 1. The crushing tower 1 is equipped with a multi-stage crushing component 2 for first vibrating and crushing the water-quenched slag and then finely grinding it, and an anti-overflow drying component 3 for multi-stage drying treatment of the powder by gradually spreading it out.

[0045] The multi-stage crushing assembly 2 includes a material support plate 21 and a grinding seat 22 fixedly connected to the inner wall of the crushing tower 1, and a rolling roller 23 rolling on the top of the material support plate 21. The top of the material support plate 21 is provided with a V-shaped groove for effectively receiving and processing stainless steel water-quenched slag, and to avoid the problem of some un-crushed water-quenched slag falling off during crushing. The rolling roller 23 has a frustum-shaped structure that is adapted to the V-shaped groove to increase the crushing contact surface and improve the crushing efficiency.

[0046] The grinding turntable 24, which is adapted to the grinding seat 22, together with the material support plate 21 and the rolling wheel 23, and the grinding turntable 22 and the grinding seat 24, can achieve multi-stage crushing of stainless steel water quenched slag and improve the preparation quality of powdered admixtures.

[0047] The anti-overflow drying assembly 3 includes multiple drying trays 31 rotatably installed inside the crushing tower 1. The multiple drying trays 31 achieve multi-stage drying treatment of water-quenched slag powder, thereby improving drying quality and efficiency. Multiple heating plates 32 are embedded inside the drying trays 31. The heating plates 32 inside the drying trays 31 are energized to heat the drying trays 31, thereby performing primary drying treatment on the powder.

[0048] A conductive ring is installed on the annular outer wall of the drying tray 31, and a corresponding clearance groove is opened on the inner wall of the crushing tower body 1. A carbon brush that contacts the conductive ring is installed in the clearance groove to provide power to the circumferentially rotating heating plate 32. A discharge port 33 is opened through the multiple drying trays 31.

[0049] The top of the crushing tower 1 is rotatably connected to a material distribution plate 11, and the bottom of the material distribution plate 11 is located on one side of the crushing wheel 23 with a material distribution port. The top of the crushing tower 1 is equipped with a feed hopper 12 that communicates with the material distribution plate 11. The water-quenched slag is placed on the material distribution plate 11 through the feed hopper 12. Through the material distribution port on the material distribution plate 11 and the rotation of the material distribution plate 11, the water-quenched slag is dispersed into the V-shaped groove on the top of the annular support plate 21. The water-quenched slag is crushed by the circumferentially rotating crushing wheel 23 in conjunction with the support plate 21.

[0050] The crushing tower body 1 is rotatably connected to a rotating rod 25 that is fixedly connected to the grinding turntable 24 and the material distribution plate 11, and a motor that drives the rotating rod 25 to rotate is installed. The rotating rod 25 is fixedly connected to a support rod that rotates with the corresponding crushing wheel 23, and a scraper 26 that slides in contact with the top of the material support plate 21. The scraper 26 is located on the side of the crushing wheel 23 away from the material distribution port, so as to avoid the scraper 26 scraping and guiding the uncrushed water quenched slag.

[0051] The scraper 26 is inclined at different lines on the outer and inner contact points of the support plate 21. The water-quenched slag fragments are continuously gathered and pushed by the inclined scraper 26, causing the fragments to fall from the support plate 21 and enter the grinding gap between the grinding turntable 24 and the grinding seat 22 for secondary grinding into powder.

[0052] The inner side of the crushing wheel 23 is rotatably connected to a rotating shaft 27 extending to its outer side. An eccentric block 28 is fixedly connected to the rotating shaft 27. A gear 29 is fixedly connected to the end of the rotating shaft 27. A toothed ring 13 that meshes with the gear 29 is fixedly connected to the inner wall of the crushing tower body 1. An installation groove for installing the toothed ring 13 is opened on the inner wall of the crushing tower body 1. A baffle ring that is rotatably connected to the rotating shaft 27 and rotatably connected to the installation groove is provided to prevent water-quenched slag fragments from entering the installation groove.

[0053] With the help of the circumferential rotation of the crushing wheel 23, combined with the meshing of the gear ring 13 and the gear 29, the rotating shaft 27 inside the crushing wheel 23 carries the eccentric block 28 to rotate, thereby driving the crushing wheel 23 to vibrate and rotate circumferentially, which helps to enhance the crushing effect of the crushing wheel 23 on the water-quenched slag.

[0054] The bottom of the rotating rod 25 is fixedly connected to multiple drying trays 31 through the I-frame 34. The rotating rod 25 connects multiple drying trays 31 through the I-frame 34 and drives the drying trays 31 to rotate synchronously. Multiple discharge ports 33 are distributed in a spiral shape to prevent the powder on multiple drying trays 31 from falling downwards and passing through multiple discharge ports 33 in sequence, thus preventing the drying treatment of the top of multiple drying trays 31 from being achieved in sequence.

[0055] A temporary storage hopper 35 is fixedly connected to the inner wall of the pulverizing tower 1 between adjacent drying trays 31. The bottom of the temporary storage hopper 35 is a long rectangular discharge port. A scraper 36 is fixedly connected to the top of each drying tray 31. The temporary storage hopper 35 and the bottom of the corresponding drying tray 31 and the scraper 36 and the top of the corresponding drying tray 31 are in sliding contact. The powder falling from the annular grinding gap between the grinding turntable 24 and the grinding seat 22 falls to the top of the drying tray 31 above for primary drying treatment.

[0056] As the drying tray 31 rotates, the scraper 36 on top of it blocks and accumulates the powder on the drying tray 31 until the discharge port 33 rotates to the position of the scraper 36, scraping the primary dried material into the temporary storage hopper 35. The material is then linearly discharged to the next drying tray 31 through the elongated discharge port at the bottom of the temporary storage hopper 35. This, combined with the rotation of the corresponding drying tray 31, achieves the effect of uniform drying. The dried powder falls to the bottom of the crushing tower 1 through the discharge port 33 on the bottom drying tray 31, and is then discharged through the discharge pipe at the bottom of the crushing tower 1.

[0057] A cam disk 37 is provided on the top of the drying tray 31, and the cam disk 37 is fixedly connected to the corresponding drying tray 31 and the I-frame 34. A metal filter screen 38 is installed between the cam disk 37 and the drying tray 31 below it. A rotary joint communicating with the cavity in the middle of the drying tray 31 is rotatably installed on the top of the I-frame 34. An air outlet pipe 39 extending to the outside of the crushing tower body 1 is connected to the rotary joint. During the multi-stage drying process, water vapor generated by drying powder in the crushing tower body 1 is extracted through the cavity formed by the middle of the multiple drying trays 31 in the I-frame 34, combined with the air outlet pipe 39 and the rotary joint.

[0058] A spiral tube 310 is installed on the outer wall of the pulverizing tower 1, and one end of the spiral tube 310 and the air outlet 39 are connected through the liquid collection box 311. An air inlet with an embedded filter screen is opened at the bottom of one side of the pulverizing tower 1. The water vapor generated during drying is extracted and discharged by the external fan through the spiral tube 310. The suction force should not be too large to prevent the powder from being pulled and flowed in large quantities. The air inlet with the embedded filter screen is used for the outside air to enter the pulverizing tower 1 to realize the flow of gas inside the pulverizing tower 1.

[0059] When water vapor is discharged through the spiral tube 310, its internal heat is transferred to the pulverizing tower 1 through the spiral tube 310 to assist in preheating the water-quenched slag during the pulverizing process, thereby further improving the drying efficiency and quality of the powder. The heat loss in the water vapor causes some of it to condense into water vapor, which then collects into the liquid collection tank 311 to prevent the evaporated water from flowing back into the pulverizing tower 1.

[0060] Example 2: Please refer to Figures 10-12 As shown, the problem that some powder is easily pulled out during water vapor separation, making it impossible to achieve complete powder recovery, can be solved by the following solution:

[0061] A cam plate 37 is provided on the top of the drying tray 31, and the cam plate 37 is fixedly connected to the corresponding drying tray 31 and the I-frame 34. A metal filter screen 38 is installed between the cam plate 37 and the drying tray 31 below it. The water vapor generated by drying the powder in the crushing tower 1 is extracted through the spiral tube 310 and the external fan.

[0062] During the extraction process, the powder material under traction is blocked by the metal filter screen 38 to prevent overflow, thus achieving full recovery of the powder material. The metal filter screen 38 is heated intermittently by the drying tray 31 to prevent water vapor from condensing and adhering to the metal filter screen 38. The top of the frame 34 is rotatably installed with a rotary joint that communicates with the cavity in the middle of the drying tray 31. An air outlet pipe 39 extending to the outside of the crushing tower body 1 is connected and installed on the rotary joint.

[0063] A movable plate 313 is fixedly connected to the scraper 36 by a spring 312 and slidably connected thereto. A guide rod 314 that slides against the cam disk 37 is installed on the movable plate 313. A cleaning brush 315 is installed on the movable plate 313. The drying tray 31 carries the metal filter screen 38 and rotates synchronously with the cam disk 37. The cleaning brush 315 on the scraper 36 cleans the annular sidewall of the metal filter screen 38.

[0064] By guiding the guide rod 314 downward through the cam plate 37 and the spring 312 resetting and rising the movable plate 313 after it moves down, the movable plate 313 carrying the cleaning brush 315 can reciprocate up and down, thus achieving synchronous cleaning of the powder on the surface of the metal filter screen 38 and effectively preventing the metal filter screen 38 from becoming clogged.

[0065] Example 3: Please refer to Figures 1-12 As shown, the present invention also proposes a method for producing admixtures using stainless steel water-quenched slag, comprising the following steps:

[0066] Step 1: The motor drives the rotating rod 25 to rotate, carrying the material distribution plate 11, the crushing wheel 23, the feeding scraper 26, the grinding turntable 24 and multiple drying plates 31 to rotate. The water-quenched slag is placed on the material distribution plate 11 through the feeding hopper 12. The water-quenched slag is dispersed into the V-shaped groove on the top of the annular support plate 21 through the material distribution port on the material distribution plate 11. The circumferentially rotating crushing wheel 23 works with the support plate 21 to crush the water-quenched slag.

[0067] Step 2: With the help of the circumferential rotation of the crushing wheel 23, combined with the meshing of the gear ring 13 and the gear 29, the rotating shaft 27 inside the crushing wheel 23 carries the eccentric block 28 to rotate, thereby driving the crushing wheel 23 to vibrate and rotate circumferentially, which helps to enhance the crushing effect of the crushing wheel 23 on the water-quenched slag. The water-quenched slag fragments are continuously gathered and pushed by the inclined feeding scraper 26, causing the fragments to fall from the material tray 21 and enter the grinding gap between the grinding turntable 24 and the grinding seat 22 for secondary grinding into powder.

[0068] Step 3: The powder falling from the annular grinding gap between the grinding turntable 24 and the grinding seat 22 falls onto the top of the drying tray 31 above. The heating plate 32 inside the drying tray 31 is energized to heat the drying tray 31, thereby performing primary drying treatment on the powder. As the drying tray 31 rotates, the scraper 36 on its top blocks and accumulates the powder on the drying tray 31 until the discharge port 33 rotates to the position of the scraper 36, scraping the primary dried material into the temporary storage hopper 35.

[0069] The material is fed linearly through the elongated discharge port at the bottom of the temporary storage hopper 35 to the next drying tray 31. The drying tray 31 rotates to perform secondary even drying. The scraper 36 blocks and accumulates the powder, and the drying tray 31 below performs multi-stage drying. The dried powder falls to the bottom of the crushing tower 1 and is then discharged through the discharge pipe at the bottom of the crushing tower 1.

[0070] Step 4: During the multi-stage drying process, the water vapor generated by the drying of powder in the pulverizing tower 1 is extracted through the spiral tube 310 and the external fan. During the extraction process, some of the powder that is pulled is blocked by the metal filter screen 38 to prevent overflow. The metal filter screen 38 is heated intermittently by the drying tray 31 to prevent the water vapor from condensing and adhering to the metal filter screen 38. When the water vapor is discharged through the spiral tube 310, its internal heat is transferred to the pulverizing tower 1 through the spiral tube 310 to preheat the water-quenched slag during the pulverizing process, further improving the drying efficiency and quality of the powder. The heat loss in the water vapor causes some of it to condense into water vapor and fall into the collection tank 311 for collection.

[0071] Step 5: During the rotation of the drying tray 31, the metal filter screen 38 and the cam plate 37 rotate synchronously. The cleaning brush 315 on the scraper plate 36 cleans the annular sidewall of the metal filter screen 38. The cam plate 37 guides the guide rod 314 downward, and the spring 312 resets the movable plate 313 after it moves down, so that the movable plate 313 carries the cleaning brush 315 in a reciprocating up and down motion. This effectively avoids the metal filter screen 38 from becoming clogged, which would prevent water vapor from being discharged efficiently and result in poor drying effect.

[0072] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

A method for producing admixtures from stainless steel water-quenched slag, employing the system for producing admixtures from stainless steel water-quenched slag as described in claim 5, characterized in that... Includes the following steps: Bulk material handling: The bulk material tray (11) rotates synchronously with the rolling wheel (23) to place the water-quenched slag into the support tray (21) in a ring-like manner; Multi-stage refining process: The rolling wheel (23) rotates in conjunction with the material support plate (21) to initially crush the water-quenched slag, and the rolling wheel (23) vibrates and strengthens the crushing effect by rotating the eccentric block (28). Then, the scraper (26) tilts and guides the crushed material to fall between the grinding turntable (24) and the grinding seat (22) for secondary grinding. Flat-lay high-efficiency drying method: The powder falls in a ring onto the top drying tray (31) for primary drying. The drying tray (31) rotates and is combined with the scraper (36) on its top to scrape the primary dried material into the temporary storage hopper (35). The material is then fed in a linear fashion to the next drying tray (31) for secondary even drying. Finally, it is combined with multiple drying trays (31) below for multi-stage drying. Thermal energy auxiliary utilization link: Through the spiral tube (310) and the external fan, the water vapor generated by the drying of powder in the crushing tower (1) is extracted to prevent powder overflow. During the discharge of water vapor, its internal heat is transferred to the crushing tower (1) through the spiral tube (310) to assist in the preheating of water quenched slag during the crushing process.
