Description

Technical Field

[0001] The invention relates to the technical field of concrete production, and in particular to high-ductility concrete mixture homogenization mixing equipment and a mixing process. Background Art

[0002] High-ductility concrete is a type of concrete with good durability and high compressive strength. It is usually used to withstand buildings, bridges and other structures that are exposed to the natural environment for a long time. Compared with ordinary concrete, high-ductility concrete is more stringent in the selection of raw materials and the matching of dosage. High-ductility concrete usually uses crushed stone or gravel with smaller particle size instead of the sand and gravel mixture commonly used in ordinary concrete. This is mainly to improve the density and durability of high-ductility concrete. At the same time, in order to improve the mechanical properties of high-ductility concrete, some auxiliary materials are often added to high-ductility concrete, such as water reducers, early strength agents, retarders, high-performance fibers (such as steel fibers, polypropylene fibers, glass fibers, etc.). The addition of these materials can significantly improve the performance of ordinary concrete in these aspects.

[0003] When producing concrete, according to the engineering requirements and design needs, the appropriate types and proportions of aggregates, types of cement, types and proportions of admixtures, etc. are selected to formulate a mix ratio plan, and then all raw materials are mixed evenly and stirred according to the mix ratio requirements. The mixing process may be carried out by manual mixing or by mixing equipment. Existing mixing equipment generally has arc-shaped blades welded on the inner wall of the mixing drum. Under the self-rotation of the arc-shaped blades on the inner wall of the mixing drum, the concrete will be continuously lifted, thrown and folded, thereby achieving rapid mixing of concrete mortar.

[0004] When using equipment to mix high-ductility concrete, if the auxiliary materials are not evenly added to the concrete, or if lumps are mixed in the auxiliary materials, agglomeration may occur in the produced concrete, greatly reducing the uniformity of the concrete, which will directly affect the structural density and strength of the concrete. At the same time, the presence of lumps will increase the viscosity of the concrete and reduce the fluidity of the concrete, which is very unfavorable for some scenarios that require fluidity. It is difficult to effectively solve the impact of lumps mixed in the high-ductility concrete on the uniformity of the high-ductility concrete by relying solely on the curved blades on the inner wall of the mixing drum.

[0005] In view of the above problems existing in the prior art, we have designed a high-ductility concrete mixture homogenization mixing equipment and mixing process. Summary of the invention

At this time, first move the material mixing component to the working position, then put the auxiliary material into the feed hopper 5, start the material mixing component, and the lumps that may exist in the auxiliary material can be broken up and evenly sprinkled into the concrete being mixed, and then add all the remaining water into the mixing drum 3, mix evenly until the auxiliary material does not clump, that is, the mixing is completed, and then the mixed high-ductility concrete can be discharged from the discharge port of the mixing drum 3.

[0102] The homogenizing component is installed inside the mixing component, and is used to quickly mix the auxiliary materials with the concrete when adding auxiliary materials. The homogenizing component includes a mounting cylinder 15, a driven bevel gear 16, a driving bevel gear 17, a rotating disk 18, a mixing part and a displacement part. A plurality of groups of mounting cylinders 15 are fixedly installed at equal distances on the rotating cylinder 6, and each group of mounting cylinders 15 is provided with two, and the two mounting cylinders 15 are symmetrically arranged relative to the rotating cylinder 6, wherein the positions of the plurality of mounting cylinders 15 and the plurality of mixing rods 7 are staggered, and a driven bevel gear is rotatably installed at the lower part of each mounting cylinder 15.

Since the annular grooves 24 are arranged inclined, the shift plates 23 will move up and down in the mounting tube 15 during the rotation process, thereby driving the corresponding sleeves 20 and the sleeve shaft 19 to slide relative to each other, thereby increasing the mixing range of the mixing frames 21 and the curved plates 22 and improving the uniformity of mixing.

[0113] Specifically, after the auxiliary material after being stirred by the crushing rod 31 enters the distribution hopper 32, as the crushing shaft 29 continues to rotate, the second motor 30 drives the first gear 37 to rotate, the first motor 11 drives the third gear 39 to rotate, the third gear 39 drives the second gear 38 to rotate, and the second gear 38 can drive the vibrating rod 35 to rotate, so that the vibrating rod 35 drives multiple cams 36 to rotate, and the cam 36 is in contact with the vibrating plate 33. As the cam 36 rotates, the vibrating plate 33 vibrates under the action of the spring 34, so that the auxiliary material entering the distribution hopper 32 is evenly discharged into the mixing drum 3 under the action of the vibrating plate 33, thereby improving the uniformity of the concrete.

[0114] In summary, when mixing high ductility concrete, firstly weigh the corresponding weight of water according to the instructions for use of the high ductility concrete, and then before starting to mix, pour a portion of the weighed water into the mixing drum 3, generally pour 80% first, and then pour cement, aggregate and other materials into the mixing drum 3 through the feed hopper 5, start the first motor 11, the first motor 11 drives the driving shaft 10 to rotate, the driving shaft 10 drives the driving gear 13 to rotate, the driving gear 13 drives the intermediate gear 14 to rotate, thereby driving the gear ring 12 to rotate through the intermediate gear 14, the gear ring 12 drives the rotating drum 6 to rotate, and the rotating drum 6 drives multiple stirring rods 7 to rotate at the same time, and the stirring rod 7 drives the hammer-shaped protrusion 9 to rotate through the spiral scraper 8, so that the concrete in the mixing drum 3 is stirred. In this process, the spiral scraper 8 will scrape off the concrete attached to the inner wall of the mixing drum 3, so that the concrete is fully stirred, and the multiple stirring rods 7 are arranged obliquely relative to the axis position of the rotating drum 6, which not only improves the stirring efficiency, but also facilitates the discharge of the concrete after it is stirred.

[0115] While the rotating cylinder 6 drives the stirring rod 7 to stir the concrete, in order to improve the uniformity of the stirring, the driving shaft 10 drives the multiple active bevel gears 17 to rotate at the same time, and the multiple active bevel gears 17 drive the corresponding driven bevel gears 16 to rotate, and the multiple driven bevel gears 16 drive the corresponding rotating disks 18 to rotate in the installation cylinder 15. While the multiple rotating disks 18 rotate, the multiple rotating disks 18 drive the corresponding sleeves 20 to rotate through the corresponding sleeves 19, and the multiple sleeves 20 drive the corresponding stirring frames 21 to rotate. Through the arrangement of the arc plate 22, the stirring of the concrete can be made more uniform during the stirring process, and it can also The possibility of agglomeration of auxiliary materials during the mixing process is reduced. At the same time, as the multiple sleeves 20 rotate, the multiple sleeves 20 will drive the corresponding shift disks 23 to rotate synchronously, and the multiple shift disks 23 will drive the corresponding sliders 25 to slide in the corresponding annular grooves 24. Since the annular grooves 24 are arranged inclined, the shift disks 23 will move up and down in the mounting tube 15 during the rotation of the shift disks 23, thereby driving the corresponding sleeves 20 and the sleeve shaft 19 to slide relative to each other, and driving the corresponding stirring frame 21 to move back and forth, which not only increases the range of mixing, but also improves the uniformity of mixing, and cooperates with the setting of the hammer-shaped protrusions 9 to further improve the uniformity and efficiency of mixing.

[0116] After the concrete is evenly stirred, auxiliary materials (such as water reducing agent, early strength agent, retarder, high-performance fiber, etc.) need to be slowly and evenly added thereto to improve its mechanical properties. First, the electric cylinder 28 is started, and the electric cylinder 28 drives the sliding frame 27 to move in the supporting frame 26 until the electric cylinder 28 drives the sliding frame 27 to move to the working position. After the sliding frame 27 moves to the working position, the sliding frame 27 is just located at the discharge end of the feed hopper 5. At this time, the second motor 30 is started, and the second motor 30 drives the crushing shaft 29 to rotate, and the crushing shaft 29 drives the crushing rod 31 to rotate, so as to stir the added auxiliary materials, reduce the possibility of forming lumps in the auxiliary materials, and at the same time make the auxiliary materials enter the distribution hopper 32 more evenly, so that the auxiliary materials are added more evenly, thereby improving the quality of concrete mixing.

[0117] After the auxiliary material stirred by the crushing rod 31 enters the distribution hopper 32, as the crushing shaft 29 continues to rotate, the second motor 30 drives the first gear 37 to rotate, the first motor 11 drives the third gear 39 to rotate, the third gear 39 drives the second gear 38 to rotate, and the second gear 38 can drive the vibration rod 35 to rotate, so that the vibration rod 35 drives multiple cams 36 to rotate, and the cam 36 contacts the vibration plate 33. As the cam 36 rotates, the vibration plate 33 vibrates under the action of the spring 34, so that the auxiliary material entering the distribution hopper 32 Under the action of the vibrating plate 33, the material is evenly and slowly discharged into the mixing drum 3, which reduces the phenomenon of the auxiliary material forming lumps during the mixing process due to the existence of lumps in the auxiliary material, or the uneven addition amount and addition speed when adding the auxiliary material, thereby avoiding the reduction of the uniformity of the high-ductility concrete due to the existence of lumps, and improving the processing efficiency. At the same time, all the remaining water is added to the mixing drum 3, and stirred evenly until the auxiliary material does not clump and the concrete has a uniform texture, that is, the mixing is completed, and then the stirred high-ductility concrete can be discharged from the discharge port of the mixing drum 3.
