Technical Field
[0001] This invention relates to the field of concrete processing technology, specifically to an energy-saving aggregate particle size control device for concrete processing. Background Technology
[0002] During construction, concrete ensures the building's structural strength. Aggregates in concrete not only provide structural support but also reduce cement usage, regulate thermal expansion and contraction, and enhance durability. Concrete aggregates are granular loose materials that act as the skeleton or filler in concrete. They are divided into two categories: coarse aggregates and fine aggregates. Coarse aggregates mainly refer to crushed stone or pebbles with a particle size greater than 4.75 mm. Crushed stone is formed by crushing and screening natural rocks, while pebbles are formed through natural weathering and water transport. Fine aggregates are sand with a particle size less than 4.75 mm, including natural sand (river sand, lake sand, etc.) and artificial sand.
[0003] In existing concrete preparation methods, after the concrete is prepared at the concrete preparation plant, the mixed cement is transported to the construction site via a rotary mixing tank on a cement truck. The cement is kept in a state of constant mixing during both preparation and transportation. During preparation, the cement, sand, and crushed stone are mixed in a ratio of 1:4:7. The concrete preparation plant is located on a platform higher than the transport truck, on which the mixing tank is installed. The tank contains the cement, sand, and crushed stone. The upper part of the mixing tank is a processing area for the sand and crushed stone. After being crushed and screened, the crushed stone is mixed with the fine sand. Because the overall size of the crushed stone is larger than that of the fine sand... Therefore, when mixing crushed stone and sand, the crushed stone and sand need to be mixed separately. For fine sand, it can be screened out by a vibrating device when passing through a screen. For crushed stone, some of the crushed stone will not be completely crushed during crushing. When it enters the screening equipment, it will block the screen holes, resulting in a reduction in the screening and mixing feed of the crushed stone side. It is necessary to stop the machine and take out the uncrushed crushed stone for separate crushing. Moreover, because of the crushed stone blockage, the feed is slow, and the feed of fine sand needs to be adjusted. Thus, the fine sand needs to be stirred separately when it enters the mixing area, which causes the fine sand to accumulate. To address this, we propose an energy-saving aggregate particle size control device for concrete processing. Summary of the Invention

The actuating ring 7 is distributed outside the processing tank 2 to rotate and actuate the actuating blocks 5.
[0035] Crushed stone enters the processing tank 2 through one of the feed ports 27 via a conveyor belt, while fine sand enters the processing tank 2 through the other feed port 27, thereby achieving separate processing of crushed stone and fine sand. After being ground separately, they are mixed and then enter the mixing tank 11 through the receiving pipe 12. The mixing tank 11 is an existing mixing device that thoroughly mixes and stirs the crushed stone, fine sand and cement.

The processing tank 2 is provided with two compression grooves 53 on its exterior, and a fixing plate 54 is connected to one end of the curved frame 52 that passes through the compression groove 53. A conical ball 55 that cooperates with the arc-shaped slope 73 is connected to the fixing plate 54. A return spring 56 is connected between the curved frame 52 and the compression groove 53.
[0039] The grinding unit has disassembly plates 92 at both ends, and three adjustment grooves 93 are provided on the disassembly plates 92. The grinding roller 91 is connected to the mounting shaft 94 which is installed in the adjustment grooves 93. The outer side of the disassembly plates 92 is connected to the inner wall of the processing tank 2 through the connecting rod 95.
[0040] When driving the grinding unit to grind crushed stone, the grinding unit is driven by a driving component 3. The driving component 3 includes a mounting housing 31 located in the middle part of the grinding unit. Three grinding rollers 91 pass through the mounting housing 31. Each of the three grinding rollers 91 is fitted with a rotating gear 32. The mounting housing 31 is provided with a driving gear 33 that meshes with the rotating gear 32. A reduction gear 34 meshes with the driving gear 33. The shafts of the reduction gear 34 and the driving gear 33 are connected to the inner wall of the mounting housing 31. A grinding motor 35 is mounted on the mounting housing 31. A transmission gear 36 is mounted on the output end of the grinding motor 35, and the transmission gear 36 meshes with the reduction gear 34.
[0041] The swing component 4 includes a first swing rod 41 disposed on one side of the mounting housing 31, and a second swing rod 42 disposed on the other side of the mounting housing 31. Sliding sleeves 43 are hinged to both the first and second swing rods 41. The sliding sleeve 43 at the top of the first swing rod 41 is connected via a first pull rod 44, and the sliding sleeve 43 at the top of the second swing rod 42 is connected via a second pull rod 45. The first and second pull rods 44 and 45 are connected to the isolation plate 24 via a reciprocating spring 49. A fixing sleeve 46 is connected to one end of the first and second pull rods 44 and 45 that slides through the processing tank 2. The bottom of the fixing sleeve 46 is hinged to one end of a crankshaft 51, and the other end of the crankshaft 51 is hinged to the fixing plate 54. A distribution plate 47 is disposed on one side of the isolation plate 24, and multiple baffles 48 are provided on both sides of the distribution plate 47, with the baffles 48 distributed outside the mounting housing 31.
[0042] The fine sand distribution component 8 is composed of multiple distribution units. Each distribution unit includes a pair of rotating sleeves 81. The rotating sleeves 81 are provided with swing grooves 82. Sliding rods 83 are distributed inside the rotating sleeves 81, and the sliding rods 83 are provided with swing protrusions 84 at the swing grooves 82. Multiple distribution cones 85 are distributed between the two rotating sleeves 81, and two elastic curved rods 86 are installed on the distribution cones 85. The elastic curved rods 86 are connected to the outer side of the swing protrusions 84.
[0043] In practical use: a conveyor belt is installed at the feed inlet 27 to transport the crushed stone and fine sand. The crushed stone enters the crushed stone screening plate 26 in the crushing chamber 22. Holes are made on the crushed stone screening plate 26 for the crushed stone to pass through, and the fine sand enters the fine sand screening plate 25 in the crushing chamber 22.
[0044] After the crushed stone enters the chamber of the crushed stone screening plate 26, because the distribution plate 47 is installed on one side of the isolation plate 24, the distribution plate 47 is inclined on both sides, and the top of the distribution plate 47 is rounded, when the crushed stone falls onto the distribution plate 47, the crushed stone slides down along the inclined plates on both sides and enters the grinding unit. The grinding unit has grinding rollers 91 of different diameters, and the diameters of the three grinding rollers 91 are distributed in a ratio of 1:2:3. The grinding motor 35 installed on the mounting housing 31 drives the transmission gear 36 to rotate. Because the transmission gear 36 drives the drive gear 33 through the reduction gear 34. The grinding rollers 91 rotate because the drive gear 33 and the rotating gear 32 distributed on the grinding rollers 91 rotate. The dimensions of the three rotating gears 32 are 1:2:3 according to the dimensions of the grinding rollers 91, so that the three grinding rollers 91 with different diameters rotate at different speeds. When the crushed stone falls onto the grinding rollers 91, the rotating grinding rollers 91 crush the crushed stone. When the crushed stone can pass through the gaps between the grinding rollers 91, it leaks directly from the gaps between the three grinding rollers 91. When the crushed stone cannot pass through the gaps between the three grinding rollers 91, the grinding rollers 91 roll and grind the crushed stone.
[0045] When fine sand enters the chamber of the fine sand screening plate 25, it first contacts the distribution cone 85 and falls along the cone to the perforations of the fine sand screening plate 25. Since the two sides of the distribution cone 85 are connected by the elastic curved rod 86 and the swing protrusion 84 on the sliding rod 83, the distribution cone 85 helps to separate the fine sand when it impacts the cone. At the same time, the fine sand drives the sliding rod 83 to slide in the rotating sleeve 81. Because the swing protrusion 84 protrudes from the swing groove 82, it prevents the fine sand from entering the rotating sleeve 81. Meanwhile, because the sliding rod 83 rotates in the rotating sleeve 81, the swing protrusion 84 separates the fine sand when it is poured in, effectively preventing the fine sand from clogging at the fine sand screening plate 25.
[0046] When the crushed stone and fine sand are poured in, the stirring motor 61 is started simultaneously. The output end of the stirring motor 61 drives the stirring main shaft 62 to rotate, thereby driving the stirring branch 63 to rotate, thus fully mixing the crushed stone screened from the crushed stone screening plate 26 and the fine sand screened from the fine sand screening plate 25. When the metal ring 64 is driven to rotate, the trigger ring 71, which is magnetically attracted to the metal ring 64, begins to rotate. The rotating ring 71 rotates along the rotating groove 72. When the rotating ring 71 rotates, the arc-shaped slope 73 rotates with the rotation of the rotating ring 71. When the arc-shaped slope 73 contacts the conical sphere 55, the arc-shaped slope 73 rotates with the rotation of the sphere 55. As the cone-shaped ball 55 is gradually pushed in, it is pushed downwards. Since the cone-shaped ball 55 is mounted on the fixed plate 54, it drives the curved frame 52 to compress the return spring 56 along the compression groove 53. When the return spring 56 is compressed to the lowest position of the compression groove 53, the cone-shaped ball 55 is pushed upwards under the elastic force of the return spring 56. At this time, the cone-shaped ball 55 is just at the highest point of the arc slope 73, transitioning to the lowest point of the arc slope 73. Since one end of the curved frame 52 is connected to the crushed stone screening plate 26 and the fine sand screening plate 25 respectively, the crushed stone screening plate 26 and the fine sand screening plate 25 move along the rotating connection with the isolation plate 24. The connection between the crushed stone screening plate 26 and the fine sand screening plate 25 and the isolation plate 24 is a rotatable hinge.
[0047] When the arc-shaped slope 73, in conjunction with the conical sphere 55, drives the fixed plate 54 to move up and down, the crankshaft 51 is hinged to one end of the fixed plate 54. When the fixed plate 54 pulls the crankshaft 51, the fixed plate 54 exerts a downward force. Its first component force along the crankshaft 51 direction, and its second component force along the horizontal direction of the first pull rod 44 or the second pull rod 45, restrict the movement of the sliding holes of the first pull rod 44 and the second pull rod 45 on the tank body 2, thereby giving the first pull rod 44 and the second pull rod 45 a horizontal component force. At the same time, since the first swing rod 41 and the second swing rod 42 are mounted on the first pull rod 44 and the second pull rod 45 through the sliding sleeve 43, the first swing rod 41 and the second swing rod 42 are also affected. On the pull rod 45, and since the tops of the first swing rod 41 and the second swing rod 42 are hinged to the sliding sleeve 43, and the bottoms of the first swing rod 41 and the second swing rod 42 are fixed on both sides of the top of the mounting housing 31, when the first pull rod 44 and the second pull rod 45 are pulled horizontally by the second horizontal force, the mounting housing 31 can be driven to swing, thereby swinging the grinding unit installed on the mounting housing 31 and shaking off the crushed stone distributed on the grinding unit. Through the reset effect of the reciprocating spring 49, the mounting housing 31 shakes regularly with the crushed stone screening plate 26, which is conducive to the crushed stone falling off after grinding.
[0048] Through the above grinding process, which simultaneously drives the screening and mixing processes, not only is a multi-processing effect achieved for crushed stone and fine sand, but the grinding and mixing processes are also increased. At the same time, the mixing and screening processes work together to achieve energy-saving control of aggregate particle size.
