Description

Technical Field

[0001] The invention belongs to the technical field of concrete additive production, and in particular relates to a mixing and roasting integrated device for producing concrete additives. Background Art

[0002] With the continuous advancement of construction technology, the requirements for cement concrete are getting higher and higher. It is not only required that concrete has adjustable setting, early strength, high strength, high fluidity, high density, high durability, low hydration heat, and light weight, but also requires low preparation cost, easy molding, and simple maintenance. To achieve these goals, concrete admixtures play an important role and have become the indispensable fifth component in concrete.

[0003] The characteristics of concrete admixtures are that they are of many varieties and small dosage. They play an important role in improving or enhancing the performance of fresh and hardened concrete. The working performance of fresh concrete is significantly improved; they can effectively control the setting time and slump loss of concrete; the later strength has a large increase; the density of concrete is increased, and the durability indicators such as impermeability, frost resistance, and carbonization resistance are greatly improved. Hardened concrete has good volume stability, etc. Therefore, it is very important to understand the adaptability of concrete admixtures and cement, the main impact of admixtures on concrete performance, to better use admixtures, handle the relationship between admixtures and cement and concrete, and give full play to the role of concrete in construction projects.

[0004] Permeable concrete is a commonly used road construction material made of aggregate, cement mineral admixture, water and additives. It is the best material for building a "sponge city".

The concrete additive capable of improving the strength of concrete and a production method thereof can improve the strength of concrete, so that the prepared concrete has a higher strength. At the same time, the high-strength concrete additive can effectively improve the anti-wear performance of concrete by adding anti-wear fillers composed of silicon nitride and zirconium oxide, can increase the curing speed of concrete, and can significantly enhance the strength of concrete after solidification, avoid cracking of concrete, and is conducive to ensuring the sufficiency of concrete reaction and improving the comprehensive performance of concrete.

[0047] An upper heating chamber 7 is provided on the outer side and the lower side of the mixing evaporation chamber 4, a roasting hopper 9 is provided in the roasting chamber 5, the roasting hopper 9 is in the shape of a funnel with a large top and a small bottom, a heating device is provided in the side wall of the roasting hopper 9, a drying hopper 10 is provided in the mixing drying chamber 6, a lower heating chamber 8 is provided at the lower part of the mixing drying chamber 6, and the upper heating chamber 7 and the lower heating chamber 8 are both connected to the roasting chamber 5;

[0048] A rotating shaft 11 is longitudinally rotatably arranged in the shell 1 , and the rotating shaft 11 passes through the openings of the upper partition 2 and the lower partition 3 and penetrates the mixing evaporation chamber 4 , the roasting chamber 5 and the mixing drying chamber 6 .

[0049] The present invention is provided with a mixed evaporation chamber 4, a roasting chamber 5 and a mixed drying chamber 6 from top to bottom according to the production steps, so that multiple production steps are organically combined together, and the material is made to flow in the equipment by gravity, without the need for transportation between various equipments, with simple process, high production efficiency and low production cost. The heat in the roasting chamber 5 is used for evaporation and drying, which is energy-saving and environmentally friendly, and further reduces the production cost. At the same time, the rotating shaft 11 runs through the mixed evaporation chamber 4, the roasting chamber 5 and the mixed drying chamber 6, and the materials in the mixed evaporation chamber 4, the roasting chamber 5 and the mixed drying chamber 6 can be stirred at the same time by using one power source, which simplifies the process and reduces the production cost again.

[0050] In order to ensure the sealing of the roasting chamber 5 and prevent the inert gas in the roasting chamber 5 from escaping when the material enters the roasting chamber 5, the mixed roasting integrated equipment also includes a sealed material storage assembly, and the two sealed material storage assemblies are respectively located at the lower side of the upper partition 2 and the lower partition 3;

[0051] The sealed material storage assembly includes a material storage barrel 12 and an opening and closing assembly. The material storage barrel 12 is a vertically arranged tube. The material storage barrel 12 is fixedly arranged on the lower side of the opening of the upper partition 2 or the lower partition 3. The two groups of opening and closing assemblies are respectively located at the upper and lower ends of the material storage barrel 12. The opening and closing assemblies make the ends of the material storage barrel 12 in an open or closed state.

[0052] In order to optimize the product structure, in this embodiment, the opening and closing assembly includes two opening and closing plates 13 that are relatively mirror-imaged. The opening and closing plates 13 are laterally slidably arranged in the shell 1. The upper and lower surfaces of the opening and closing plates 13 of the opening and closing assembly located at the upper part of the sealed material storage assembly are respectively sealed and slidably fitted to the lower surface of the upper partition 2 or the lower partition 3 and the upper end surface of the material storage barrel 12. The upper surface of the opening and closing plates 13 of the opening and closing assembly located at the lower part of the sealed material storage assembly is sealed and slidably fitted to the lower end surface of the material storage barrel 12.

[0053] The two opening and closing plates 13 of the opening and closing assembly move synchronously in opposite directions; when the two opening and closing plates 13 are located at the innermost side, the inner end surfaces of the two opening and closing plates 13 are sealed to each other and sealed and slidably fit to the outer wall of the rotating shaft 11; when the two opening and closing plates 13 are located at the outermost side, the inner end surfaces of the two opening and closing plates 13 are both located on the outside of the storage barrel 12.

[0054] In order to facilitate the control of the opening and closing of the opening and closing plate 13, the opening and closing assembly also includes an opening and closing rod 14 and a guide rod 15. The opening and closing rod 14 and the guide rod 15 are both arranged along the translation direction of the opening and closing plate 13. The opening and closing rod 14 and the guide rod 15 are respectively located on both sides below the opening and closing plate 13. The guide rod 15 is fixedly arranged in the shell 1. The two opening and closing plates 13 are both slidably fitted on the guide rod 15. The opening and closing rod 14 is rotatably arranged on the shell 1. One end of the opening and closing rod 14 is provided with a positive thread segment and the other end is provided with a negative thread segment. The two opening and closing plates 13 are respectively threadedly fitted on the positive thread segment and the negative thread segment of the opening and closing rod 14.

[0055] In order to ensure the sealing performance and rotation performance between the opening and closing plate 13 and the rotating shaft 11, and to prevent the rotating shaft 11 from shaking during rotation due to errors in processing and installation, which is not conducive to sealing, a sealing rotation structure is provided at the sealing joint between the rotating shaft 11 and the opening and closing plate 13. The sealing rotation structure includes a positioning plate 16 and a sealing sleeve 17. The positioning plate 16 is fixedly sleeved on the rotating shaft 11, and the two positioning plates 16 are arranged at intervals. The sealing sleeve 17 is annular and is rotatably sleeved on the rotating shaft 11 and is located between the two positioning plates 16. The upper and lower end surfaces of the sealing sleeve 17 are respectively sealed and slidably fitted on the two positioning plates 16. The inner diameter value of the sealing sleeve 17 is greater than the outer diameter value of the rotating shaft 11. The middle part of the outer side surface of the circumference of the sealing sleeve 17 is provided with a concave pressing groove, and the bottom surface of the pressing groove is in a "-shape;

[0056] The positioning plate 16 and the sealing sleeve 17 are both made of reinforced polytetrafluoroethylene material. The inner end surface of the opening and closing plate 13 is provided with a rubber layer, which is made of fluororubber.

[0057] When the opening and closing assembly is in a closed state, the opening and closing plate 13 clamps the sealing sleeve 17, and the upper and lower end surfaces of the sealing sleeve 17 are forced to tilt upward and then downward, thereby ensuring the sealing between the upper and lower end surfaces of the sealing sleeve 17 and the two positioning plates 16; a gap is left between the circumferential outer wall of the rotating shaft 11 and the inner wall of the sealing sleeve 17, and the rotation of the rotating shaft 11 will not be affected when the rotating shaft 11 has a certain deformation. At the same time, the sealing sleeve 17 has a certain translation distance to avoid the two opening and closing plates 13 being unable to clamp the sealing sleeve 17 at the same time when the two opening and closing plates 13 move asynchronously. As long as the circumferential inner wall of the sealing sleeve 17 does not move out of the range of the positioning plate 16, the sealing performance can be guaranteed, thereby improving practicality.

[0058] In order to make the high-temperature inert gas in the roasting chamber 5 as close as possible to the material in the drying bucket 10, thereby improving the drying efficiency, the lower heating chamber 8 includes a return air chamber 18 and an air inlet chamber 19 arranged at intervals in the upper and lower parts. The air inlet chamber 19 is located on the bottom surface of the mixing drying chamber 6, and an air inlet is arranged in the middle of the top surface of the air inlet chamber 19. The return air chamber 18 is annular, and an air outlet is arranged on the bottom surface of the return air chamber 18. The longitudinal section of the drying bucket 10 is concave and is laterally slidably arranged on the top surface of the air inlet chamber 19. The bottom and top surfaces of the drying bucket 10 are respectively provided with air inlet holes and air outlet holes. When the drying bucket 10 is in the working position, the air inlet holes and the air outlet holes are respectively sealed and connected to the air inlet of the air inlet chamber 19 and the air outlet of the return air chamber 18.

[0059] To further optimize the product structure, in this embodiment, the integrated mixed roasting equipment also includes an air inlet pipe 20 and an air return pipe 21. The upper and lower ends of the air inlet pipe 20 are respectively connected to the lower part of the upper heating chamber 7 and the air inlet chamber 19, the middle part of the air inlet pipe 20 is connected to the upper part of the roasting chamber 5, the upper and lower ends of the return pipe 21 are respectively connected to the upper part of the upper heating chamber 7 and the return air chamber 18, and the middle part of the return pipe 21 is connected to the lower part of the roasting chamber 5.

[0060] In order to ensure the stirring effect and scrape the evaporated material to the roasting chamber 5, a stirring and scraping assembly is provided at a section of the rotating shaft 11 located in the mixing and evaporating chamber 4, and a plurality of stirring and scraping assemblies are evenly distributed along the circumference of the outer wall of the rotating shaft 11;

[0061] The scraping assembly includes a scraping rod 22 and a scraping plate 23. The scraping rod 22 is arranged horizontally in a 7-shape. The horizontal section of the scraping rod 22 is arranged radially along the rotating shaft 11 and its end is fixedly connected to the rotating shaft 11. The scraping plate 23 is arranged along the length direction of the vertical section of the scraping rod 22. The upper end of the scraping plate 23 is fixedly connected to the scraping rod 22. The outer end of the scraping plate 23 slides and fits to the inner wall of the mixing and evaporation chamber 4, and the inner end is located on the inner side of the opening of the upper partition 2.

[0062] A stirring rod 24 is provided at a section of the rotating shaft 11 located in the mixing evaporation chamber 4. A plurality of stirring rods 24 are evenly distributed along the circumference of the outer wall of the rotating shaft 11. The stirring rod 24 is located in the drying hopper 10. The upper end of the stirring rod 24 is fixedly connected to the rotating shaft 11, and the lower end is tilted downward.

[0063] In order to ensure the stirring effect and avoid interference between the drying bucket 10 and the stirring rod 27 when the drying bucket 10 is translated, a section of the rotating shaft 11 located in the mixing and drying chamber 6 is provided with a rotating stirring assembly, which includes a rotating disk 25, a rotating rod 26 and a stirring rod 27.

[0065] When the drying bucket 10 is pulled out, the top of the side wall of the drying bucket 10 touches the stirring rod 27, and the stirring rod 27 flips to one side and does not block the translation of the drying bucket 10; during mixing, the rotating shaft 11 drives the stirring rod 27 to rotate through the rotating disk 25.

[0066] Embodiment 2:

[0067] During production, all opening and closing components are first in a closed state. Methanol is first input into the mixing evaporation chamber 4, and then melamine is added and stirred. After mixing evenly, silicon nitride and zirconium oxide are added. After mixing evenly again, the high-temperature inert gas in the roasting chamber 5 is introduced into the upper heating chamber 7. The high-temperature inert gas heat exchanges to evaporate the liquid in the mixing evaporation chamber 4, and then the inert gas after heat exchange flows back to the heating chamber.

[0068] Open the opening and closing assembly at the upper end of the sealed material storage assembly on the lower side of the upper partition 2, and scrape all the dry materials into the storage barrel 12 with the stirring and scraping plate 23, and then close the opening and closing assembly at the upper end of the sealed material storage assembly, and then open the opening and closing assembly at the lower end of the sealed material storage assembly, and the dry materials fall into the roasting hopper 9, and close the opening and closing assembly at the upper end of the sealed material storage assembly, and the dry materials are roasted in the roasting hopper 9 to obtain a roasted product.

[0069] The drying hopper 10 is pulled out of the shell 1 and the modifier solution is injected into it, and then the drying hopper 10 is pushed into the shell 1, and the roasting product falls into the drying hopper 10 through the sealed material storage assembly on the lower side of the lower partition 3. After the roasting product and the modifier solution are evenly mixed, the high-temperature inert gas in the roasting chamber 5 is introduced into the air inlet chamber 19 and enters the drying hopper 10. The high-temperature inert gas heats and dries the material in the drying hopper 10 through heat exchange, and then the inert gas after heat exchange flows back to the heating chamber through the return air chamber 18.

[0070] The dried material is crushed and mixed with other raw materials, and then put into a hot mixing reactor to prepare the concrete additive through hot mixing polymerization reaction.

[0071] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
