It includes a storage silo with a feeding mechanism for aggregates on its upper side. A controller is fixedly connected to one side of the silo. By setting up a screening plate and a feeding assembly, the incoming aggregates are effectively separated into large and small particle sizes for sequential conveying. Based on the principle that aggregates with higher density are heavier in the same volume, the device accurately determines whether the contents of the silo are light, ordinary, or heavy aggregates, and then sends them to the corresponding storage area for storage.

Description

Technical Field

[0001] This invention relates to the field of concrete raw material storage technology, specifically to a concrete raw material storage device for construction waste recycling. Background Technology

[0002] During the construction of building projects, design changes occur frequently due to various reasons such as changes requested by the owner or design defects. This makes some of the purchased or processed building materials unable to adapt to the new design scheme, resulting in a large amount of waste.

[0003] To avoid wasting these wastes, they need to be recycled and utilized. First, the construction waste is initially cleaned to remove debris such as wood, plastic, paper, and metal. Then, the larger pieces of construction waste, such as bricks and concrete blocks, are crushed using equipment such as jaw crushers and impact crushers to break them into smaller particles. The crushing process can be repeated multiple times as needed to achieve the required aggregate particle size. Since the aggregate is a raw material for concrete, the crushed aggregate is then poured into the interior of a concrete raw material storage silo for storage.

[0004] Existing aggregate storage methods involve storing various aggregates of different sizes and densities together. Since different aggregate sizes have their own suitable uses, such as coarse aggregates providing a strength skeleton and fine aggregates filling voids, it is impossible to accurately obtain the required aggregate size after mixing. This affects the mix design and performance of materials such as concrete. Furthermore, it is difficult to accurately distinguish and weigh aggregates of different densities when they are mixed together, leading to increased batching errors and making it impossible to accurately batch according to the designed mix proportions, thus affecting the quality of concrete.

[0005] Therefore, it is necessary to design a concrete raw material storage device for construction waste recycling that can separate and store aggregates of different particle sizes and densities. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. By setting up separate screening plates and feeding components, the incoming aggregates are effectively separated into large and small particle sizes and conveyed sequentially. Based on the principle that the higher the density of the aggregate, the heavier it is in the same volume space, the system accurately determines whether the contents of the box are light aggregates, ordinary aggregates, or heavy aggregates, and then sends them to the corresponding storage area for storage. This effectively prevents aggregates of different densities from mixing together, making it difficult to accurately distinguish and weigh them, which would increase the batching error and prevent the precise batching according to the design mix ratio, thus affecting the quality of concrete. The system achieves the effect of automatically distinguishing aggregate particle size and density for storage.

[0018] 2. After the aggregate is discharged from the feeding box, the feeding box is ejected by a spring. This not only drives the feeding box back to its original position to transport the next batch of aggregate, but also drives the T-shaped block to slide along the chute. While sliding, the gear above rotates rapidly, which in turn drives the fan to rotate rapidly. The air force generated by the fan's rapid rotation blows away some of the aggregate stuck in the corners of the slide plate through the air outlet, effectively preventing too much aggregate from getting stuck in the corners and causing subsequent aggregate to accumulate at the stuck position.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1, please refer to Figure 1-10 The present invention provides a technical solution: a concrete raw material storage device for construction waste recycling, comprising a storage bin 1, a feeding mechanism 2 for entering aggregates on the upper side of the storage bin 1, a controller 3 fixedly connected to one side of the storage bin 1, a main valve 4 for discharging aggregates fixedly connected to the lower side of the storage bin 1, a screening plate 5 for screening aggregates of different particle sizes fixedly connected inside the storage bin 1, a Z-shaped partition 6 for separating large-diameter aggregates and small-diameter aggregates fixedly connected to the lower side of the screening plate 5, a small-diameter separation mechanism 7 for density differentiation of small-diameter aggregates on one side of the Z-shaped partition 6, a large-diameter separation mechanism 8 for density differentiation of large-diameter aggregates on the other side of the Z-shaped partition 6, and a weighing mechanism 9 for storing aggregates of different particle sizes and densities on the lower side of the large-diameter separation mechanism 8.

[0038] Please see Figure 1 A baffle 11 is fixedly connected to one side of the storage compartment 1. A platform 12 is provided on the lower side of the controller 3 and the platform 12 is fixedly connected to the storage compartment 1. A ladder 13 is provided on one side of the platform 12 and the ladder 13 is fixedly connected to the storage compartment 1.

[0039] The specific explanation of the above structure is as follows: the baffle 11 is used to block the aggregate that falls outside, so as to prevent the aggregate from falling on the head of the workers when they are standing above the platform 12 to control it, causing a safety accident.

[0040] Please see Figure 2 The feeding mechanism 2 includes a first motor 22 fixedly connected to one side of the storage chamber 1. The output end of the first motor 22 passes through the storage chamber 1 and is fixedly connected to the feeding gate 21. One side of the feeding gate 21 is connected to the bearing of the storage chamber 1 through a rotating shaft.

[0041] The specific description of the above structure is as follows: the rotation of the output end of the first motor 22 is used to control the rotation of the feed door 21, thereby opening the feed door 21 to send the aggregate into the storage bin 1, or closing the feed door 21 to prevent dust and moisture from entering the storage bin 1.

[0042] Please see Figure 3 The weighing mechanism 9 includes a first weighing box 91, a second weighing box 92, and a third weighing box 93 fixedly connected to one side of the Z-shaped partition 6. A fourth weighing box 94, a fifth weighing box 95, and a sixth weighing box 96 are fixedly connected to the other side of the Z-shaped partition 6. The lower sides of the first weighing box 91, the second weighing box 92, the third weighing box 93, the fourth weighing box 94, the fifth weighing box 95, and the sixth weighing box 96 are all inclined surfaces, and a discharge valve 97 is fixedly connected to the lowest surface of the inclined surface.

[0043] The specific description of the above structure is as follows: the first weighing box 91 is used to hold large-diameter heavy aggregates, the second weighing box 92 is used to hold large-diameter ordinary aggregates, the third weighing box 93 is used to hold large-diameter light aggregates, the fourth weighing box 94 is used to hold small-diameter heavy aggregates, the fifth weighing box 95 is used to hold small-diameter ordinary aggregates, and the sixth weighing box 96 is used to hold small-diameter light aggregates. The opening of the discharge valve 97 is used to convey the type of aggregate required by the operator. The first weighing box 91, the second weighing box 92, the third weighing box 93, the fourth weighing box 94, the fifth weighing box 95, and the sixth weighing box 96 can all weigh the aggregates inside them in real time.

[0044] Please see Figure 4The small particle size separation mechanism 7 and the large particle size separation mechanism 8 have the same structure. The large particle size separation mechanism 8 includes a slide plate 82 fixedly connected to the inside of the storage bin 1. A material collection trough 83 is provided on one side of the slide plate 82. Anti-jamming components 81 for blowing away aggregates stuck at the included angle on both sides of the slide plate 82 are provided on both sides of the slide plate 82. A material passage component 85 is provided on the lower side of the material collection trough 83. A feeding component 86 is provided on one side of the material passage component 85. A discharge component 87 is provided on the lower side of the feeding component 86. Guide slide plates 84 are provided on both sides of the feeding component 86. One guide slide plate 84 is fixedly connected to the storage bin 1, and the other guide slide plate 84 is fixedly connected to the Z-shaped partition 6.

[0045] The specific explanation of the above structure is as follows: after being screened by the screening plate 5, the large-diameter aggregate and the small-diameter aggregate reach the slide plates 82 on both sides of the Z-shaped partition 6 respectively. The density is distinguished by the feeding component 86, so that the aggregates of different densities are transported to different areas for storage.

[0046] Please see Figure 7 and Figure 9 The feeding assembly 86 includes a slider 863 slidably connected inside the guide plate 84. A feeding box 865 is fixedly connected to one side of the slider 863. A level sensor 864 is fixedly connected to the upper side of the feeding box 865. Several springs 861 are fixedly connected to one side of the feeding box 865. A fixing plate 862 is fixedly connected to the other side of the several springs 861 and is fixedly connected to the storage chamber 1. A solenoid valve 866 is fixedly connected to the upper side of the other side of the feeding box 865. Two first electric push rods 867 are evenly fixedly connected to one side of the feeding box 865. A friction plate 868 is fixedly connected to the output end of each first electric push rod 867. The two sides of the feeding box 865 are respectively hinged to two second connecting rods 812.

[0047] The specific explanation of the above structure is as follows: Spring 861 is used to support the feeding box 865 and the aggregate inside, preventing the feeding box 865 from sliding downwards. The elastic force of spring 861 can be set according to the actual particle size and density of the aggregate. The level sensor 864 can be an ultrasonic level gauge, which measures the aggregate level by emitting and receiving ultrasonic waves. The probe of the ultrasonic level gauge is installed on the top of the box and emits ultrasonic pulses towards the aggregate surface. The ultrasonic waves are reflected back after encountering the aggregate surface and are received by the probe. The level gauge calculates the distance between the aggregate surface and the probe based on the time difference between the emission and reception of the ultrasonic waves, thereby determining the aggregate level height. When the level height reaches the full load height of the box, a full signal is issued. The extension of the output end of the first electric push rod 867 is used to control the friction plate 868 to abut against the guide plate 84. When the friction force between the friction plate 868 and the guide plate 84 is greater than the elastic force of spring 861, the feeding box 865, where the aggregate has not completely fallen, cannot be ejected back to its original position.

[0048] Please see Figure 8 The feeding assembly 85 includes a feed pipe 854 fixedly connected to the lower side of the collecting trough 83. A third discharge pipe 853 is connected through the lower side of the feed pipe 854. A second discharge pipe 852 is slidably connected inside the third discharge pipe 853. A first discharge pipe 851 is slidably connected inside the second discharge pipe 852. The other end of the first discharge pipe 851 is fixedly connected to the input end of the solenoid valve 866. Both ends of the first discharge pipe 851, the second discharge pipe 852 and the third discharge pipe 853 are chamfered.

[0049] The specific description of the above structure is as follows: the aggregate enters the interior of the feeding box 865 through the feed pipe 854, the third discharge pipe 853, the second discharge pipe 852, and the first discharge pipe 851 in sequence. When the feeding box 865 slides along the guide plate 84, the third discharge pipe 853, the second discharge pipe 852, and the first discharge pipe 851 can freely extend and retract.

[0050] Please see Figure 10 The discharge assembly 87 includes a material passage block 871 fixedly connected to the lower side of the feeding box 865. A second electric push rod 874 is fixedly connected to one side of the material passage block 871. A connecting block 873 is fixedly connected to the output end of the second electric push rod 874. A baffle plate 872 is fixedly connected to one side of the connecting block 873 and the baffle plate 872 is slidably connected to the material passage block 871.

[0051] The specific explanation of the above structure is as follows: the extension of the output end of the second electric push rod 874 is used to control the baffle plate 872 to slide, thereby opening the outlet below the material block 871, so that the aggregate is sent into the area with the corresponding density for storage.

[0052] When the conveying equipment transports the aggregate into the storage bin 1, the aggregate is screened by the screening plate 5 and fed into both sides of the Z-shaped partition 6. Small-diameter aggregate falls above the slide plate 82 on the right side of the Z-shaped partition 6, while large-diameter aggregate falls above the slide plate 82 on the left side of the Z-shaped partition 6, and enters the collection trough 83 along the slide plate 82. Since the weight of the feeding assembly 86 is much less than the elastic force of the spring 861, in the initial state, the spring 861 is fully extended, and the second discharge pipe 852 and the first discharge pipe 851 are retracted into the third discharge pipe 853. Aggregate passes through the collection trough 83 in sequence through the feed pipe 854, the third discharge pipe 853, the second discharge pipe 852, and the first discharge pipe 851. The solenoid valve 866 opens, and the aggregate continuously slides into the inside of the feeding box 865. The level sensor 864 emits ultrasonic waves downwards in real time to monitor the accumulation height of the aggregate. When the level sensor 864 detects that the feeding box 865 is full, it sends a full signal to the controller 3. The controller 3 controls the output end of the second electric push rod 874 to extend out and slide the control baffle 872, thereby opening the outlet below the material passage block 871.

[0053] When the incoming aggregate is lightweight aggregate, since the weight of the feed box 865 filled with lightweight aggregate is less than the initial elastic force of the spring 861, the spring 861 does not deform and remains at its original length. The position of the feed box 865 remains unchanged, and the aggregate falls into the interior of the third weighing box 93 through the material passage block 871 for storage.

[0054] When the incoming aggregate is ordinary aggregate, since the weight of the feeding box 865 filled with ordinary aggregate is greater than the initial elastic force of the spring 861, the spring 861 is continuously compressed in static equilibrium, causing the feeding box 865 to slide diagonally downward until its elastic force is balanced with the weight of the feeding box 865 filled with ordinary aggregate. At this time, the spring 861 is in a semi-compressed state, and the feeding box 865 slides above the second weighing box 92. The aggregate falls into the interior of the second weighing box 92 through the material passage block 871 for storage.

[0055] When the incoming aggregate is heavy aggregate, the weight of the feeding box 865 filled with heavy aggregate is much greater than the initial elastic force of the spring 861. The spring 861 is continuously compressed until its elastic force is balanced with the weight of the feeding box 865. At this time, the spring 861 is compressed to its limit position, and the feeding box 865 slides above the first weighing box 91. The aggregate falls into the interior of the first weighing box 91 through the material passage block 871 for storage.

[0056] To prevent the weight of the feeding box 865 from gradually decreasing as the aggregate falls, the spring 861 begins to rebound before the aggregate has completely fallen. Therefore, when the level sensor 864 detects that the feeding box 865 is fully loaded, the controller 3 controls the output end of the first electric push rod 867 to extend, controlling the friction plate 868 to press against the guide plate 84. Since the friction between the friction plate 868 and the guide plate 84 is greater than the elastic force of the spring 861, the feeding box 865, whose aggregate has not completely fallen, will not be ejected back to its original position. This continues until the level sensor 864 detects that all the aggregate inside the feeding box 865 has fallen. At this point, the controller 3 controls the output end of the first electric push rod 867 to retract. The friction plate 868 no longer presses against the guide plate 84, and the feeding box 865 is driven back to its original position by the spring 861.

[0057] The density differentiation method for small-diameter aggregates is the same as that for large-diameter aggregates, and will not be repeated here.

[0058] When aggregate is needed, the staff only needs to open the corresponding discharge valve 97.

[0059] By setting up screening plates 5 and feeding components 86 respectively, the incoming aggregates are effectively separated into large and small particle sizes and conveyed sequentially. Based on the principle that the higher the density of aggregates in the same volume space, the heavier they are, the system accurately determines whether the contents of the box are light aggregates, ordinary aggregates, or heavy aggregates, and then sends them to the corresponding storage area for storage. This effectively prevents aggregates of different densities from mixing together, making it difficult to accurately distinguish and weigh them, which would increase batching errors and prevent the precise batching according to the design mix ratio, thus affecting the quality of concrete. The system achieves the effect of automatically distinguishing aggregate particle size and density for storage.

[0060] In Example 2, due to the complex shape of aggregate particles, with sharp edges or flat surfaces, and their concentrated fall onto the edge of the slide plate 82, they are prone to getting stuck in the corners of the slide plate 82 during the fall or slide, hindering their continued sliding. If the residual aggregate stuck in the corners of the slide plate 82 is not cleaned regularly, the aggregate will accumulate over time, resulting in more aggregate getting stuck in the corners. Moreover, most of the residual aggregate will be moved by aggregates of different densities in the future, causing the two types of aggregates of different densities to be mixed and stored together, affecting the accurate batching of concrete in the future. Therefore, the following structure is designed to solve the above technical problems.

[0061] Please see Figures 4-6 The anti-jamming component 81 includes positioning plates 813 fixedly connected to both sides of the slide plate 82. Each positioning plate 813 has several air vents 814 on its upper side and a sliding groove 816 on its lower side. Several toothed columns 815 are evenly arranged on the inner wall of the positioning plate 813. A T-shaped block 819 is slidably connected inside the sliding groove 816. A gear 818 is rotatably connected to the upper side of the T-shaped block 819. The gear 818 meshes with the toothed columns 815. A fan 817 is fixedly connected to the upper side of the gear 818 through a connecting shaft. A first connecting rod 811 is hinged to the lower side of the T-shaped block 819. A second connecting rod 812 is hinged to the other end of the first connecting rod 811.

[0062] The specific explanation of the above structure is as follows: When the feeding box 865 returns to its original position to distinguish the density of the next batch of aggregates, the feeding box 865 slides while driving the second connecting rod 812 to move, thereby indirectly driving the first connecting rod 811 to move. While moving, the second connecting rod 812 and the first connecting rod 811 bend adaptively. As the first connecting rod 811 moves, it drives the T-shaped block 819 to slide along the slide groove 816. While sliding, it drives the gear 818 above to rotate rapidly, thereby indirectly driving the fan 817 to rotate rapidly. The wind force generated by the rapid rotation of the fan 817 blows away some of the aggregate stuck at the edge corner of the slide plate 82 through the air outlet 814.

[0063] After the aggregate is discharged from the feeding box 865, the feeding box 865 is ejected by the spring 861. This not only drives the feeding box 865 back to its original position for the next batch of aggregate, but also drives the T-shaped block 819 to slide along the slide groove 816. While sliding, the gear 818 above rotates rapidly, which in turn indirectly drives the fan 817 to rotate rapidly. The wind generated by the rapid rotation of the fan 817 blows away some of the aggregate stuck in the corner of the slide plate 82 through the air outlet 814, effectively preventing too much aggregate from getting stuck in the corner and causing subsequent aggregate to accumulate at the stuck position.
