Description

Technical Field

[0001] The present invention relates to the technical field of concrete mixing equipment, in particular to ultra-high performance concrete mixing equipment. Background Art

[0002] Concrete, abbreviated as "砼", is a general term for engineering composite materials in which aggregate is cemented into a whole by cementing materials. The term concrete generally refers to Portland cement concrete obtained by mixing cement as cementing material, sand and stone as aggregate, with water (which may contain additives and admixtures) in a certain proportion, which is also called ordinary concrete. It is widely used in civil engineering, and Portland cement concrete is usually mixed by a concrete mixer. Among many types of concrete, UltraHigh Performance Concrete (UHPC for short) is known for its "three high properties", namely high durability, high workability and high strength. Differences of UHPC from ordinary concrete or high-performance concrete include: no coarse aggregate is used, silica fume and fibers (steel fibers or composite organic fibers) must be used, the cement consumption is large, and the water-binder ratio is very low, etc.

[0003] Existing concrete mixers have various operation modes according to different application processes. Among them, the disc mixer is a common mixing device. Concrete raw materials are poured into the disc mixer from an opening at the top, and a fixed disk drives a stirring rod to make stirring blades stir the raw materials. Since the raw materials contain materials such as sand, stone and steel fibers, long-term collision between the stirring rod, stirring blades and these hard materials will cause surface damage to the stirring rod and stirring blades. In order to avoid the reduction of raw material stirring efficiency caused by severe damage to the stirring rod and stirring blades, it is necessary to disassemble the fixed disk to replace the stirring rod and stirring blades. However, since the fixed disk and the transmission shaft are generally fixed by bolts, and the fixed disk is in contact with raw materials for a long time, a concrete layer adheres to the connection between the fixed disk and the transmission shaft, making it difficult to efficiently disassemble the fixed disk. Meanwhile, during pouring of raw materials, in order to prevent large-particle materials or agglomerated fibers from entering the device and colliding with the stirring blades, a sieve plate is usually installed at the top of the device. However, when disassembling and assembling the fixed disk, it is necessary to first remove a plurality of bolts connecting the sieve plate to the device, and then replace the fixed disk after removing the sieve plate.

[0004] In order to achieve efficient replacement of the fixed disk, thereby further improving the efficiency and quality of concrete mixing and prolonging the service life of the device, we propose an ultra-high performance concrete mixing device. Summary of the Invention

A lifting rod 2014 is connected to the inside of the lifting collar 2011 via the connecting turntable 205. The outer wall of the lifting rod 2014 is integrally formed with a limiting baffle 2013 that slides up and down with the docking cylinder 2015 and the connecting turntable 205. A second spring 2012 is sleeved on the outer wall of the lifting rod 2014. The two ends of the second spring 2012 are in contact with the outer wall of the limiting baffle 2013 and the inner wall of the connecting turntable 205, respectively. A docking turntable 202 is provided on the upper surface of the fixed plate 9 and sleeved on the outer wall of the lifting rod 2014 and the docking cylinder 2015. A positioning cylinder 201 is integrally formed at the bottom end of the docking turntable 202, penetrating the fixed plate 9 to the inner wall of the connecting turntable 205. Two positioning sliders 208 are symmetrically formed on the outer wall of the positioning cylinder 201.

[0024] The fixing components include: a sealing rotating plate 203 rotatably connected to the top of the docking turntable 202 via a rotating shaft; an anti-slip pad is fixedly connected to the bottom end of the sealing rotating plate 203; an adjusting bolt 204 threadedly connected to the docking turntable 202 is provided on the lower surface of the sealing rotating plate 203; a lifting frame 207 slidably connected to the docking turntable 202 is provided on the lower surface of the adjusting bolt 204; the lifting frame 207 contacts the outer wall of the lifting rod 2014; a docking plug 2010 penetrating into the positioning plug 201 is fixedly connected to the top end of the drive shaft 6; the top outer walls of the docking plug 2010 and the docking plug 2015 are both frustum-shaped; and an arc-shaped groove for the docking plug 2015 to slide is provided on the docking turntable 202.

[0025] In this embodiment: When installing the fixed plate 9, the fixed plate 9 is placed on the upper surface of the connecting turntable 205, and multiple docking sleeves 2015 are sleeved on it. Simultaneously, it is ensured that the lifting groove on the fixed plate 9 and the lifting groove on the connecting turntable 205 are at the same horizontal line. Then, the docking turntable 202 is pushed to sleeve the positioning sleeve 201 onto the outer wall of the docking block 2010. Then, the docking turntable 202 is pushed to cause the positioning sleeve 201 to descend along the outer wall of the docking block 2010. During this process, the positioning slider 208, driven by the positioning sleeve 201, moves along... The inner wall of the lifting groove on the fixed plate 9 and the connecting turntable 205 enters the interior of the connecting turntable 205. At the same time, the docking turntable 202 sleeves the outer walls of multiple docking cylinders 2015. When the outer wall of the lifting rod 2014 contacts the inner wall of the docking turntable 202, the lifting rod 2014 slides along the inner wall of the docking cylinder 2015, the connecting turntable 205, and the lifting collar 2011 under the pressure of the docking turntable 202. At the same time, the limiting baffle 2013 compresses the second spring 2012 along the inner wall of the docking cylinder 2015 under the drive of the lifting rod 2014.

[0026] When the lower surface of the docking turntable 202 contacts the upper surface of the fixed plate 9, the docking turntable 202 is manually driven to rotate along the outer wall of the docking insert 2015. At this time, the positioning slider 208 slides along the inner wall of the connecting turntable 205 under the drive of the docking turntable 202 through the positioning insert 201. When the docking turntable 202 cannot rotate due to the obstruction of the docking insert 2015, the second spring 2012 pushes the limit baffle 2013 through rebound to make the lifting rod 2014 slide back to its original position. At the same time, the lifting frame 207 contacts the lower surface of the adjusting bolt 204 along the inner wall of the lifting frame 207 under the push of the lifting rod 2014. At this time, the docking turntable 202 can be prevented from rotating or rising and falling by the engagement of the lifting rod 2014 and the positioning slider 208, thereby realizing the squeezing and fixing of the fixed plate 9. Then, the screening and washing mechanism 3 can realize the screening of concrete raw materials and the impact dispersion of fiber materials.

[0027] Then, the motor 4 is started to drive the transmission shaft 6 to rotate along the inner wall of the fixed cylinder 5. At the same time, the connecting turntable 205 and the docking block 2010 rotate synchronously under the drive of the transmission shaft 6. At this time, the fixed plate 9 drives the lifting rod 2014 to move the stirring blade 7 through the stirring rod 8 under the drive of the transmission shaft 6, so as to stir the raw materials.

[0028] Then, the raw materials for concrete mixing are poured into the inside of the mixing drum 1. During this process, the water pump is started to send clean water from the water tank through the screening and washing mechanism 3, which can effectively suppress the dust phenomenon of raw materials and screen larger materials. Adjusting the water pump pressure can appropriately increase the water pressure when feeding fiber materials that are prone to clumping, so as to impact and disperse the clumped materials, thereby effectively reducing the wear of the mixing blades 7 while achieving uniform feeding.

[0029] When the mixing blade 7 needs to be replaced, the above operation is reversed. At this time, the sealing plate 203 is rotated around the rotating shaft. Then, the adjusting bolt 204 is lowered by rotating the tool to press the lifting frame 207. At this time, the lifting frame 207 presses the lifting rod 2014 along the inner wall of the docking turntable 202 until the lifting frame 207 contacts the upper surface of the docking insert 2015. Then, the above operation is reversed by rotating the docking turntable 202. The fixed plate 9 can be easily disassembled, and the mixing blade 7, mixing rod 8, and fixed plate 9 can be easily replaced, which is beneficial to improving the mixing efficiency of concrete raw materials.

[0030] In a preferred embodiment of the present invention, the screening and washing mechanism 3 includes: A support ring 305 is fixedly connected to the top of the mixing drum 1. Multiple spray heads 302 are circumferentially mounted on the top of the support ring 305. A third water supply pipe 304, extending through to the outside of the bottom of the support ring 305, is fixedly connected to the bottom of each spray head 302. A second water supply pipe 303, integrally formed with the third water supply pipe 304, is located below the support ring 305. A first water supply pipe 301 is integrally formed on the outer wall of the second water supply pipe 303. The outer wall of the docking turntable 202 is provided with… A second sieve plate 309 is fixedly connected to the inner wall of the support ring 305. A third sieve plate 3011 is provided on the upper surface of the second sieve plate 309, which contacts the outer wall of the docking turntable 202. A fourth sieve plate 3012 is provided on the upper surface of the third sieve plate 3011, which also contacts the outer wall of the docking turntable 202. A first sieve plate 306 is provided on the upper surface of the fourth sieve plate 3012, which also contacts the outer wall of the docking turntable 202. The first sieve plate 306, the second sieve plate 309, and the third sieve plate 3011 are connected together. The top of both the sieve plate 3011 and the fourth sieve plate 3012 has a sieve opening extending to the outside of the bottom. The bottom of the first sieve plate 306 is integrally formed with a movable push plate 308 that contacts the upper surface of the second sieve plate 309. The top of the support ring 305 is provided with a fixing bolt 307 that passes through the support ring 305, the first sieve plate 306, the movable push plate 308, and the second sieve plate 309 for threaded connection. The first water supply pipe 301, the spray head 302, the second water supply pipe 303, and the third... The inner cavities of the water supply pipes 304 are all interconnected. A water pump is fixedly connected to the end of the first water supply pipe 301 away from the second water supply pipe 303. The water pump is fixedly connected to the water tank through a pipe. The top of the second screen plate 309, the third screen plate 3011, and the fourth screen plate 3012 are all provided with limiting grooves 3010. The bottom of the first screen plate 306, the fourth screen plate 3012, and the third screen plate 3011 are all integrally formed with movable sliders 3013 that are slidably connected to the limiting grooves 3010.

[0031] In this embodiment: by pulling the first screen plate 306 to slide along the outer wall of the docking turntable 202 and the inner wall of the support ring 305, the movable push plate 308 moves under the drive of the first screen plate 306 and separates from the outer walls of the third screen plate 3011 and the fourth screen plate 3012. At the same time, the movable slider 3013 on the first screen plate 306 slides along the inner wall of the upper limit groove 3010 of the fourth screen plate 3012 under the drive of the first screen plate 306. When the movable slider 3013 contacts the end of the inner wall of the upper limit groove 3010, the fourth screen plate 3012 slides along the outer wall of the docking turntable 202 under the drive of the first screen plate 306 via the movable slider 3013. At the same time, the movable slider 3013 on the fourth screen plate 3012 slides along the inner wall of the upper limit groove 3010 on the third screen plate 3011 under the drive of the fourth screen plate 3012. When the inner wall of the movable slider 3013 contacts the end of the upper limit groove 3010, the fourth screen plate 3012 slides along the outer wall of the docking turntable 202 via the movable slider 3013. When the ends of the inner walls of the 10 screens come into contact, the third screen plate 3011 slides along the outer wall of the docking turntable 202 under the drive of the fourth screen plate 3012 via the movable slider 3013. At the same time, the movable slider 3013 on the third screen plate 3011 slides along the inner wall of the upper limit groove 3010 of the second screen plate 309 under the drive of the third screen plate 3011. When the movable slider 3013 comes into contact with the inner wall of the end of the limit groove 3010, the movable push plate 308 comes into contact with the upper surface of the second screen plate 309. During the movement of the first screen plate 306, the fourth screen plate 3012, and the third screen plate 3011, they slide along the outer wall of the fixed sliding ring inside the support ring 305 via the sliding sleeve groove. Then, by rotating the fixing bolt 307 through the tool, the support ring 305, the first screen plate 306, the movable push plate 308 and the second screen plate 309 are threadedly connected, which can realize the screening of concrete raw materials and the impact dispersion of agglomerated fiber materials.

[0032] When the raw materials for concrete mixing are poured into the mixing drum 1, the water pump is started to deliver clean water from the water tank to the spray head 302 through the first water supply pipe 301, the second water supply pipe 303, and the third water supply pipe 304. Then, the clean water is sprayed onto the opening of the support ring 305 through the spray head 302, which can effectively suppress the dust phenomenon of raw materials. At the same time, the larger materials in the raw materials can be screened through the first screen plate 306, the second screen plate 309, the third screen plate 3011, and the fourth screen plate 3012, thereby effectively reducing the wear of the mixing blades 7.

[0033] In a preferred embodiment of the present invention, the outer walls of the upper and lower ends of the lifting rod 2014 are both hemispherical, and the top end of the lifting collar 2011 is provided with a plurality of positioning slots that match the outer walls of the lifting rod 2014. The outer wall of the vertical section of the lifting collar 2011 is T-shaped.

[0034] In this embodiment: through the cooperation between the hemispherical outer wall and the positioning slot, the lifting rod 2014 can be inserted into the inside of the lifting collar 2011 under the pressure of the docking turntable 202, thereby limiting and fixing the connecting turntable 205 and effectively preventing the connecting turntable 205 from rotating synchronously with the docking turntable 202 during the rotation of the docking turntable 202.

[0035] In a preferred embodiment of the present invention, the outer wall of the positioning slider 208 is hemispherical, and the fixed disk 9 and the connecting turntable 205 are both provided with lifting grooves for the positioning slider 208 to slide up and down. The inner wall of the connecting turntable 205 is provided with a moving groove for the positioning slider 208 to slide.

[0036] In this embodiment: through the mutual cooperation of the hemispherical outer wall with the lifting slide and the moving slide, the positioning slider 208 can be engaged with the inner wall of the connecting turntable 205, and the positioning insert 201 can limit the lifting and lowering of the docking turntable 202.

[0037] In a preferred embodiment of the present invention, the inner wall of the support ring 305 is vertically and equidistantly formed with a plurality of fixed slip rings, and the first sieve plate 306, the third sieve plate 3011, and the fourth sieve plate 3012 are all provided with sliding sleeve grooves that match the outer wall of the fixed slip rings.

[0038] In this embodiment, the first screen plate 306, the third screen plate 3011, and the fourth screen plate 3012, which can be stacked on top of each other by multiple fixed slip rings, are limited and supported. When the first screen plate 306, the third screen plate 3011, and the fourth screen plate 3012 slide along the outer wall of the docking turntable 202, the first screen plate 306, the third screen plate 3011, and the fourth screen plate 3012 can be limited by the cooperation between the fixed slip rings and the sliding sleeve groove.

[0039] The working principle of this invention is as follows: When installing the fixed disk 9, it is placed on the upper surface of the connecting turntable 205, and multiple docking cylinders 2015 are sleeved on it. Simultaneously, it is ensured that the lifting groove on the fixed disk 9 and the lifting groove on the connecting turntable 205 are at the same horizontal line. Then, the docking turntable 202 is pushed to tightly fit against the outer walls of the first screen plate 306, the moving push plate 308, the second screen plate 309, the third screen plate 3011, and the fourth screen plate 3012. The positioning cylinder 201 is sleeved on the outer wall of the docking block 2010. Then, the docking turntable 202 is pushed to cause the positioning cylinder 201 to descend along the outer wall of the docking block 2010. During this process, the positioning slider 208, driven by the positioning insert 201, moves along the inner wall of the lifting groove on the fixed plate 9 and the connecting turntable 205 and enters the interior of the connecting turntable 205. At the same time, the docking turntable 202 engages with the outer walls of multiple docking inserts 2015. When the outer wall of the lifting rod 2014 contacts the inner wall of the docking turntable 202, the lifting rod 2014 slides along the inner wall of the docking insert 2015, the connecting turntable 205, and the lifting collar 2011 under the pressure of the docking turntable 202. At the same time, the limiting baffle 2013, driven by the lifting rod 2014, compresses the second spring 2012 along the inner wall of the docking insert 2015 and contracts.

[0040] When the lower surface of the docking turntable 202 contacts the upper surface of the fixed plate 9, the docking turntable 202 is manually rotated along the outer wall of the docking insert 2015. At this time, the positioning slider 208 slides along the inner wall of the connecting turntable 205 under the drive of the docking turntable 202 through the positioning insert 201. When the docking turntable 202 cannot rotate due to the obstruction of the docking insert 2015, the second spring 2012 pushes the limit baffle 2013 through rebound to make the lifting rod 2014 slide back to its original position. At the same time, the lifting frame 207 is pushed by the lifting rod 2014 and contacts the lower surface of the adjusting bolt 204 along the inner wall of the lifting frame 207. At this time, the engagement of the lifting rod 2014 and the positioning slider 208 can prevent the docking turntable 202 from rotating or rising and falling, thereby achieving the squeezing and fixing of the fixed plate 9.

[0041] Then, the first screen plate 306 is pulled to slide along the outer wall of the docking turntable 202 and the inner wall of the support ring 305. At this time, the movable push plate 308 moves under the drive of the first screen plate 306 and separates from the outer walls of the third screen plate 3011 and the fourth screen plate 3012. At the same time, the movable slider 3013 on the first screen plate 306 slides along the inner wall of the upper limit groove 3010 of the fourth screen plate 3012 under the drive of the first screen plate 306. When the movable slider 3013 contacts the end of the inner wall of the upper limit groove 3010, the fourth screen plate 3012 slides along the outer wall of the docking turntable 202 under the drive of the first screen plate 306 via the movable slider 3013. At the same time, the movable slider 3013 on the fourth screen plate 3012 slides along the inner wall of the upper limit groove 3010 on the third screen plate 3011 under the drive of the fourth screen plate 3012. When the inner wall of the movable slider 3013 contacts the upper limit groove 3010, the fourth screen plate 3012 slides along the outer wall of the docking turntable 202 via the movable slider 3013. When the ends of the inner walls of the groove 3010 come into contact, the third screen plate 3011 slides along the outer wall of the docking turntable 202 under the drive of the fourth screen plate 3012 via the movable slider 3013. At the same time, the movable slider 3013 on the third screen plate 3011 slides along the inner wall of the upper limit slide groove 3010 of the second screen plate 309 under the drive of the third screen plate 3011. When the movable slider 3013 comes into contact with the inner wall of the end of the limit slide groove 3010, the movable push plate 308 comes into contact with the upper surface of the second screen plate 309. During the movement of the first screen plate 306, the fourth screen plate 3012, and the third screen plate 3011, they slide along the outer wall of the fixed sliding ring inside the support ring 305 through the sliding sleeve groove. Then, by rotating the fixing bolt 307 with a tool, the bolts pass through the support ring 305, the first screen plate 306, the movable push plate 308, and the second screen plate 309, thus realizing the sieving of concrete raw materials.

[0042] Then, the motor 4 is started to drive the transmission shaft 6 to rotate along the inner wall of the fixed cylinder 5. At the same time, the connecting turntable 205 and the docking block 2010 rotate synchronously under the drive of the transmission shaft 6. At this time, the fixed plate 9 drives the lifting rod 2014 to move the stirring blade 7 through the stirring rod 8 under the drive of the transmission shaft 6, so as to stir the raw materials.

[0043] Then, the raw materials for concrete mixing are poured into the mixing drum 1. During this process, the water pump is started to deliver clean water from the water tank to the spray head 302 through the first water supply pipe 301, the second water supply pipe 303, and the third water supply pipe 304. Then, the clean water is sprayed onto the opening of the support ring 305 through the spray head 302, which can effectively suppress the phenomenon of raw material dust. At the same time, the first screen plate 306, the second screen plate 309, the third screen plate 3011, and the fourth screen plate 3012 can screen the materials that are larger in volume or prone to clumping, thereby effectively reducing the wear of the mixing blades 7.

[0044] When the mixing blade 7 needs to be replaced, the first screen plate 306, the third screen plate 3011, and the fourth screen plate 3012 can be reset by reversing the above operation. At this time, the sealing rotating plate 203 is rotated around the rotating shaft. Then, the adjusting bolt 204 is lowered by rotating the tool to press the lifting frame 207. At this time, the lifting frame 207 presses the lifting rod 2014 along the inner wall of the docking turntable 202 until the lifting frame 207 contacts the upper surface of the docking insert 2015. Then, the above operation is reversed by rotating the docking turntable 202, which can realize the convenient disassembly of the fixed plate 9 and the convenient replacement of the mixing blade 7, mixing rod 8, and fixed plate 9, which is beneficial to improving the mixing efficiency of concrete raw materials.

[0045] The above description is merely 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.
