Description

[0043] Embodiment one: please refer to Figures 1-11 As shown in the prior art, the synchronous straight powder extraction method is often used in the drying process, which will extract part of the water vapor generated during drying, causing the powder to absorb water vapor again, resulting in incomplete drying. The following solutions can solve the problem:

[0044] A system for producing admixture from stainless steel water quenched slag in the embodiment includes a crushing tower body 1, a multi-stage crushing assembly 2 inside the crushing tower body 1, which first vibrates and crushes the water quenched slag and then refines it, and an anti-spreading drying assembly 3, which is provided with a multi-stage drying treatment for flattening the powder step by step;

[0045] The multi-stage crushing assembly 2 includes a material supporting disc 21 and a grinding seat 22 fixedly connected to the inner wall of the crushing tower body 1, and a rolling wheel 23 located at the top of the material supporting disc 21. The top of the material supporting disc 21 is provided with a V-shaped groove for effective handling of the stainless steel water quenched slag and avoiding the problem of part of the uncrushed water quenched slag falling during rolling. The rolling wheel 23 is in a conical structure and is adapted to the V-shaped groove to increase the rolling contact surface and improve the crushing efficiency;

[0046] And a grinding turntable 24 matched with the grinding seat 22. The material supporting disc 21, the rolling wheel 23, the grinding turntable 22 and the grinding seat 24 work together to realize multi-stage crushing of the stainless steel water quenched slag and improve the preparation quality of the powdered admixture;

[0047] The anti-spreading drying assembly 3 includes a plurality of drying trays 31 rotatably installed inside the crushing tower body 1. The water quenched slag powder is subjected to multi-stage drying treatment by the plurality of drying trays 31, thereby improving the drying quality and efficiency. The inside of the drying tray 31 is embedded with a plurality of heating plates 32. The heating plates 32 in the drying tray 31 are powered to heat the drying tray 31, thereby performing primary drying treatment on the powder;

[0048] The annular outer wall of the drying disc 31 is provided with a conductive ring, and the inner wall of the crushing tower body 1 is provided with a corresponding accommodation groove, and a carbon brush in contact with the conductive ring is arranged in the accommodation groove, which is used for power supply treatment of the circumferentially rotating heating plate 32. The plurality of drying discs 31 are all provided with a discharging port 33.

[0049] The top of the crushing tower body 1 is rotatably connected with a scattering disc 11, and the bottom of the scattering disc 11 is provided with a scattering port on one side of the rolling wheel 23. The top of the crushing tower body 1 is provided with a feeding hopper 12 in communication with the scattering disc 11. The water-quenched slag is placed on the scattering disc 11 through the feeding hopper 12, and is scattered to the top V-shaped groove of the annular supporting disc 21 through the scattering port on the scattering disc 11 and the rotation of the scattering disc 11. The water-quenched slag is crushed by the circumferentially rotating rolling wheel 23 in cooperation with the supporting disc 21.

[0050] The crushing tower body 1 is rotatably connected with a rotating rod 25 fixedly connected with the grinding turntable 24 and the scattering disc 11, and is provided with a motor for driving the rotation of the rotating rod 25. The rotating rod 25 is fixedly connected with a supporting rod rotating with the corresponding rolling wheel 23 and a discharging scraper 26 in sliding contact with the top of the supporting disc 21. The discharging scraper 26 is located on the side of the rolling wheel 23 away from the scattering port, so as to avoid the discharging scraper 26 from guiding the uncrushed water-quenched slag;

[0051] The discharging scraper 26 is obliquely arranged at different lines of the outer circle contact point and the inner circle contact point of the supporting disc 21. The crushed water-quenched slag is continuously gathered and pushed by the inclined discharging scraper 26, so that the crushed slag is guided to fall from the supporting disc 21 into the grinding gap between the grinding turntable 24 and the grinding seat 22 for secondary grinding and powdering.

[0052] The inside of the rolling wheel 23 is rotatably connected with a rotating shaft 27 extending to the outside thereof. The rotating shaft 27 is fixedly connected with an eccentric block 28. The end of the rotating shaft 27 is fixedly connected with a gear 29. The inner wall of the crushing tower body 1 is fixedly connected with a gear ring 13 engaged with the gear 29. The inner wall of the crushing tower body 1 is provided with a mounting groove for mounting the gear ring 13. The rotating shaft 27 is rotatably connected with a material blocking ring rotatably connected with the mounting groove, so as to prevent the crushed water-quenched slag from entering the mounting groove;

[0053] By the circumferential rotation of the rolling wheel 23, the gear ring 13 is engaged with the gear 29, the rotating shaft 27 in the rolling wheel 23 is driven to rotate with the eccentric block 28, and the rolling wheel 23 is driven to vibrate and rotate circumferentially, thereby assisting in strengthening the crushing effect of the rolling wheel 23 on the water-quenched slag.

[0054] The bottom of the rotating rod 25 is fixedly connected with the plurality of drying discs 31 through the channel frame 34. The rotating rod 25 connects the plurality of drying discs 31 through the channel frame 34 and drives the drying discs 31 to rotate synchronously. The plurality of discharge ports 33 are distributed in a spiral shape, so that the powder on the plurality of drying discs 31 can pass through the plurality of discharge ports 33 in sequence and be subjected to the residence drying treatment on the top of the plurality of drying discs 31 in sequence.

[0055] The temporary storage hopper 35 is fixedly connected between the adjacent drying discs 31 on the inner wall of the crushing tower body 1. The bottom of the temporary storage hopper 35 is an elongated discharge port. The scraping plate 36 is fixedly connected to the top of each drying disc 31. The temporary storage hopper 35 is in sliding contact with the bottom of the corresponding drying disc 31 and the scraping plate 36 is in sliding contact with the top of the corresponding drying disc 31. 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 disc 31 above for primary drying treatment.

[0056] With the rotation of the drying disc 31, the scraping plate 36 on the top of the drying disc 31 blocks and accumulates the powder on the drying disc 31. When the discharge port 33 rotates to the position of the scraping plate 36, the primary dried material is scraped into the temporary storage hopper 35 and discharged in a linear manner through the elongated discharge port at the bottom of the temporary storage hopper 35 to the next drying disc 31. The corresponding drying disc 31 rotates to achieve the effect of uniform drying treatment. The dried powder falls through the discharge port 33 on the bottom drying disc 31 to the bottom of the crushing tower body 1 and is then discharged through the discharge pipe at the bottom of the crushing tower body 1.

[0057] The top of the drying disc 31 is provided with a cam disc 37, and the cam disc 37 is fixedly connected with the corresponding drying disc 31 and the channel frame 34. A metal filter screen 38 is installed between the cam disc 37 and the drying disc 31 below. A rotating joint that communicates with the middle cavity of the drying disc 31 is rotatably installed on the top of the channel frame 34. An air outlet pipe 39 extending to the outside of the crushing tower body 1 is installed on the rotating joint. During the multi-stage drying process, the cavity formed by the middle parts of the plurality of drying discs 31 in the channel frame 34, in combination with the air outlet pipe 39 and the rotating joint, extracts the water vapor generated by drying the powder in the crushing tower body 1.

[0058] A spiral pipe 310 is installed on the outer wall of the crushing tower body 1, and the spiral pipe 310 communicates with one end of the air outlet pipe 39 through a liquid collecting tank 311. An air inlet with an embedded filter screen is formed on one side and the bottom of the crushing tower body 1. The water vapor generated during drying is extracted and drained through the spiral pipe 310 and the fan outside the crushing tower body 1. The suction force cannot be too large to prevent the powder from being pulled and flowing significantly. The air inlet with the embedded filter screen is used for the outside air to enter the crushing tower body 1, realizing the flow of the gas inside the crushing tower body 1.

[0059] When the water vapor is discharged through the spiral pipe 310, the internal heat is transmitted to the crushing tower body 1 through the spiral pipe 310, the water quenched slag in the crushing process is assisted to be preheated, the drying efficiency and quality of the powder are further improved, the water vapor is condensed into water vapor due to the loss of the internal heat of the water vapor, and then the water droplets formed are collected in the collecting tank 311 to prevent the evaporated water from flowing back to the inside of the crushing tower body 1.

[0060] Embodiment two: please refer to Figures 10-12 As shown, in order to solve the problem that part of the powder is dragged out when the water vapor is separated, and the powder cannot be fully recovered, the following scheme can be used to solve the problem:

[0061] The top of the drying disc 31 is provided with a cam disc 37, and the cam disc 37 is fixedly connected with the corresponding drying disc 31 and the channel-shaped frame 34. A metal filter screen 38 is installed between the cam disc 37 and the drying disc 31 below the cam disc 37. The water vapor generated by drying the powder in the crushing tower body 1 is extracted through the spiral pipe 310 and the fan outside.

[0062] During the extraction process, the part of the powder dragged out is blocked and prevented from overflowing through the metal filter screen 38, so that the powder is fully recovered. The metal filter screen 38 is heated by the drying disc 31 at intervals, so that the water vapor is prevented from being condensed into water vapor and adhered to the metal filter screen 38. A rotating joint that communicates with the middle cavity of the drying disc 31 is rotatably installed on the top of the channel-shaped frame 34. An air outlet pipe 39 extending to the outside of the crushing tower body 1 is installed in communication on the rotating joint.

[0063] The scraping plate 36 is fixedly connected with a movable plate 313 in sliding connection therewith through a spring 312. A guide rod 314 in sliding abutment with the cam disc 37 is installed on the movable plate 313. A cleaning brush 315 is installed on the movable plate 313. The drying disc 31 carries the metal filter screen 38 and rotates synchronously with the cam disc 37, and cooperates with the cleaning brush 315 on the scraping plate 36 to clean the annular side wall of the metal filter screen 38.

[0064] The downward guiding of the guide rod 314 by the cam disc 37 and the upward resetting of the movable plate 313 after moving downward by the spring 312 realize the reciprocating lifting movement of the movable plate 313 carrying the cleaning brush 315, so that the powder on the surface of the metal filter screen 38 is cleaned synchronously, and the metal filter screen 38 is effectively prevented from being blocked.

[0067] Step two: the circumferential rotation of the rolling wheel 23 is combined with the meshing of the gear ring 13 and the gear 29 to drive the rotating shaft 27 in the rolling wheel 23 to rotate, and then drive the rolling wheel 23 to vibrate and rotate in the circumferential direction, thereby assisting in strengthening the crushing effect of the rolling wheel 23 on the water quenched slag, the crushed slag is continuously gathered and guided by the inclined discharging scraper 26, so that the crushed slag is guided to fall from the supporting disc 21 into the grinding gap between the grinding turntable 24 and the grinding seat 22 for secondary grinding and powdering treatment;

[0070] Step four: during the multi-stage drying process, the water vapor generated by the drying of the powder in the crushing tower body 1 is extracted through the spiral pipe 310 and the fan outside, and part of the powder is blocked by the metal filter screen 38 during the extraction process to prevent overflow, the metal filter screen 38 is heated by the drying disc 31 at intervals to avoid the condensation of water vapor on the metal filter screen 38, and the internal heat of the water vapor is transferred to the crushing tower body 1 through the spiral pipe 310 when the water vapor is discharged, thereby assisting in preheating the water quenched slag during the crushing process, further improving the drying efficiency and quality of the powder, and the internal heat of the water vapor is lost to cause part of the water vapor to condense into water vapor and fall into the liquid collecting tank 311 for collection;

[0071] Step five: in the rotation process of the drying disc 31, the metal filter screen 38 is driven to rotate synchronously with the cam disc 37, the cleaning brush 315 on the scraping plate 36 is matched to clean the annular side wall of the metal filter screen 38, and the downward guiding of the guide rod 314 by the cam disc 37 and the reset rising of the movable plate 313 after the downward movement of the spring 312 are combined to realize the reciprocating lifting movement of the movable plate 313 carrying the cleaning brush 315, so that the clogging of the metal filter screen 38 is effectively avoided, the water vapor is difficult to be efficiently discharged, and the poor drying effect caused thereby is avoided.

9. A method for producing an admixture using stainless steel water-quenched slag, using a system for producing an admixture using stainless steel water-quenched slag according to any one of claims 1 to 8, characterized in that: The following steps are involved: Bulk material processing: the bulk material tray (11) rotates synchronously with the rolling wheel (23) to pile the water-quenched slag onto the supporting tray (21) in a circular following manner; Multi-stage refinement process: The rolling wheel (23) rotates in coordination with the supporting plate (21) to initially crush the water-quenched slag, and the eccentric block (28) rotates to vibrate the rolling wheel (23) to assist in strengthening the crushing effect, and then the scraper (26) tilts to guide the crushed material to fall between the grinding turntable (24) and the grinding seat (22) for secondary grinding. Flat-laying high-efficiency drying method: the powder falls onto the top drying plate (31) in a ring shape for primary drying. The drying plate (31) rotates and combines with the scraper plate (36) on the top to scrape the primary dried material into the temporary storage hopper (35). The material is then discharged linearly onto the next drying plate (31) for secondary even-laying drying. The powder is then combined with multiple drying plates (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 powder drying in the pulverizing tower body (1) is extracted to prevent the powder from overflowing. During the discharge of the water vapor, the internal heat is transferred to the pulverizing tower body (1) through the spiral tube (310), thereby assisting in preheating the water-quenched slag during the pulverizing process.
