Construction waste recycled aggregate processing device

Abstract

The application discloses a building waste recycled aggregate processing device and relates to the technical field of building waste crushing. In order to solve the problems of incomplete cleaning of soft sundries and uneven wetting, the aggregate falling from the feeding shell falls into water inside the overflow bin. Since the water is pumped from the inside of the circulating tank to the inside of the overflow bin, the output end of the water outlet pipe is lower than the lower side of the overflow port, and the water enters the water outlet pipe and flows out of the overflow port upward. In this process, the floating effect of the sundries is ingeniously utilized. Whether the sundries are suspended in the water or adhere to the aggregate, the water from the bottom to the top will flush the sundries to the inside of the circulating tank from the overflow port, and the circulating tank is filtered by the filter screen arranged at the upper end of the circulating tank. At this time, the water circulation is completed, the sundries cleaning can be performed unlimited times, the cleaning effect is remarkable, and the whole aggregate is immersed in the water, so that the aggregate as a whole is wetted, and the surface of the aggregate is evenly wetted.

Description

Technical Field

[0001] This invention relates to the field of construction waste crushing technology, and in particular to a construction waste recycled aggregate processing device. Background Technology

[0002] Crushing construction waste before processing recycled aggregates is crucial. The goal is to reduce large, complex pieces of construction waste, such as concrete blocks and bricks, to a suitable particle size to meet subsequent processing requirements. Various crushing equipment is available. Jaw crushers use moving and stationary jaw plates to compress materials, making them suitable for processing large, hard materials, such as large concrete blocks. Cone crushers use inner and outer cones for compression and grinding, excelling at processing medium-sized, high-hardness materials that have undergone preliminary crushing. Impact crushers rely on high-speed hammers to impact materials, suitable for soft and medium-hard construction waste, and can produce cubic-shaped aggregates.

[0003] However, in existing aggregate recycling technologies, soft impurities such as plastic sheets or paper scraps need to be removed before crushing. The current method involves using hooks to catch these soft impurities before crushing. This method not only requires manual intervention to clean the impurities entangled in the hooks after a certain amount has been removed, leading to troublesome cleaning and low work efficiency, but also results in impurities that are wrapped around or adhered to the aggregates being difficult to remove, leading to incomplete cleaning. In addition, the aggregates also need to be surface-wetted before cleaning, which is currently done by spraying. This results in uneven wetting of the aggregate surface, and the amount of dust during crushing is still likely to be high.

[0004] Therefore, there is a need for a device for processing recycled aggregates from construction waste. Summary of the Invention

[0005] In order to solve all or some of the above problems, the present invention aims to provide a construction waste recycled aggregate processing device that can solve the problems of incomplete cleaning and uneven wetting of soft debris.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a construction waste recycled aggregate processing device, comprising a lower casing and a water circulation component, wherein a feeding mechanism is installed on the inner side of the lower casing, and circulation tanks are provided on both sides of the lower casing; An overflow chamber is provided on the inner side of the lower casing, and overflow ports are provided on both sides of the upper end of the lower casing. The overflow chamber and the overflow ports are connected. The water circulation component includes a water pump and an output pipe installed at the output end of the water pump. The input end of the water pump is installed at the bottom inside the circulation tank. A water distribution pipe is installed at the output end of the output pipe, and a water outlet pipe is provided at the output end of the water distribution pipe. The water outlet pipe is located inside the overflow chamber, and the output end of the water outlet pipe is lower than the bottom of the overflow port. The aggregate falls into the overflow chamber and gets wet. The water pump draws water out of the inside of the circulation tank and flows out from the water outlet pipe. It flows upward from the bottom of the overflow chamber, carrying the impurities mixed in the aggregate from the overflow chamber through the overflow port into the circulation tank. The aggregate is then fed by the feeding mechanism.

[0007] Furthermore, the unloading component one and unloading component two have the same structure. Unloading component one includes a servo motor one and a transmission column installed at the output end of the servo motor one. Conveying blades are provided on the outside of the transmission column.

[0008] Furthermore, a discharge hopper is provided inside the lower casing at the bottom of the overflow hopper, and a drain channel is also provided at the bottom of the lower casing, which connects the discharge hopper to the circulation tank.

[0009] Furthermore, a material distribution block is installed on the lower casing located in the middle of the inner side of the overflow chamber, and a set of water outlet pipes is installed at the lower inner side of the material distribution block, which simultaneously discharge water to both sides of the material distribution block.

[0010] Furthermore, a feed shell is installed at the upper end of the lower casing, and a crushing roller and a tilting roller are arranged inside the feed shell. The crushing roller is rotatably connected to the feed shell, and the tilting roller is movably connected to the feed shell. Drive components are arranged at both ends of the feed shell.

[0011] Furthermore, the driving component includes a second servo motor, the driving end of which is provided with a driving column, and a transmission belt is provided on the outside of the driving column. The end of the transmission belt away from the driving column is wrapped around the outside of a first roller provided on the crushing roller.

[0012] Furthermore, a drive gear is installed on the drive column, and a reciprocating component is provided on the outside of the drive gear. The reciprocating component is slidably connected to the feed housing. A connecting component is installed on one end of the reciprocating component. One end of the connecting component is sleeved on the outside of the second roller on the tilting roller. A driven gear is fixedly provided on the outside of the second roller. A limiting tooth plate is provided on the upper end of the driven gear. The limiting tooth plate is fixedly installed in the side wall of the feed housing. The driven gear is meshed with the limiting tooth plate.

[0013] Furthermore, the reciprocating component is generally elliptical or rectangular, and upper and lower teeth are provided on opposite inner surfaces of the reciprocating component, with the driving teeth meshing with the upper or lower teeth.

[0014] Furthermore, a material distribution assembly is installed at the lower end of the reciprocating component. The material distribution assembly includes a connecting plate and a material distribution plate installed at the lower end of the connecting plate. A slider is fixedly installed at the lower end of the material distribution plate, and the slider is movably connected to the upper end of the material distribution block.

[0015] Furthermore, both feeding component one and feeding component two are matched with corresponding discharge bins, and the diameter of the discharge bin corresponding to feeding component one is larger than the diameter of the discharge bin corresponding to feeding component two.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention proposes a construction waste recycled aggregate processing device. After the aggregate falling from the feed shell into the overflow chamber, it preferentially falls into the water located inside the overflow chamber. Since the water is pumped from the inside of the circulation tank to the inside of the overflow chamber, and the output end of the water outlet is lower than the bottom of the overflow port, the water enters from the water outlet and flows upward from the overflow port. In this process, not only is the floating effect of the debris cleverly utilized, but both the debris suspended in the water and the debris attached to the aggregate are flushed from the bottom up from the overflow port into the inside of the circulation tank and filtered by the filter screen set at the upper end of the inside of the circulation tank. At this time, the water circulation is also completed. The debris can be cleaned an unlimited number of times, and the cleaning effect is significant. Moreover, the entire aggregate is submerged in water, so that the entire aggregate is wetted, and the surface of the aggregate is evenly moistened.

[0017] 2. The present invention proposes a construction waste recycled aggregate processing device. The aggregate is fed into the upper part of the feed shell by a conveying mechanism or manually. At this time, the aggregate is located above the crushing roller and the tilting roller. A servo motor is started, driving the drive column to rotate, which in turn drives the transmission belt to drive the crushing roller to rotate counterclockwise. With the cooperation of the tilting roller, the crushing roller can pre-crush the aggregate. This crushing force is relatively small, and it can tap the surface of the aggregate, facilitating the separation of impurities adhering to the aggregate from the aggregate surface, facilitating subsequent cleaning of floating and overflowing impurities, and improving the purity of the aggregate. Simultaneously, the rotation of the drive column can drive the drive teeth to rotate. When the drive tooth meshes with the upper tooth, it can drive the connecting piece to move to the left, which in turn drives the tilting roller to move to the left, increasing the distance between the tilting roller and the crushing roller. At the same time, the driven gear meshes with the limiting tooth plate, causing the tilting roller to rotate clockwise. This can work with the crushing roller to prevent aggregate from getting stuck on the upper end of the tilting roller and the crushing roller, and also allow large aggregate to pass through the tilting roller and the crushing roller. As the drive tooth continues to rotate, when the drive tooth meshes with the lower tooth, the tilting roller rotates counterclockwise, which in turn flips the large aggregate in the opposite direction, further preventing aggregate from accumulating and getting stuck, ensuring smooth aggregate conveying, and improving work efficiency.

[0020] 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.

[0021] like Figures 1-2As shown, a construction waste recycled aggregate processing device includes a lower casing 1 and a water circulation component 5. A feed shell 6 is installed at the upper end of the lower casing 1, and a feeding mechanism is installed on the inner side of the lower casing 1. The feeding mechanism includes a feeding component 2 and a feeding component 3. A conveyor belt can be installed at the lower end of the lower casing 1 to transport the processed aggregate to the input end of the crusher. The lower end of the lower casing 1 can also be directly connected to the input end of the crusher. Circulation tanks 4 are provided on both sides of the lower casing 1, and the water circulation component 5 is installed on the circulation tanks 4 and the lower casing 1.

[0022] like Figures 1-2 as well as Figures 6-7 As shown, the inner side of the feed shell 6 is provided with a crushing roller 7 and a tilting roller 8. The crushing roller 7 is rotatably connected to the feed shell 6, and the tilting roller 8 is movably connected to the feed shell 6.

[0023] Drive components 9 are provided at both ends of the feed housing 6. The drive components 9 include a second servo motor 91. The drive end of the second servo motor 91 is provided with a drive column 92. A transmission belt 93 is provided on the outside of the drive column 92. The end of the transmission belt 93 away from the drive column 92 is sleeved on the outside of the first roller 71 provided on the crushing roller 7. A drive tooth 94 is also installed on the drive column 92. A reciprocating part 95 is provided on the outside of the drive tooth 94. The reciprocating part 95 is slidably connected to the feed housing 6. A connecting part 96 is installed on one end of the reciprocating part 95. One end of the connecting part 96 is sleeved on the outside of the second roller 81 provided on the tilting roller 8. A driven gear 82 is fixedly provided on the outside of the second roller 81. A limiting tooth plate 16 is provided on the upper end of the driven gear 82. The limiting tooth plate 16 is fixedly installed in the side wall of the feed housing 6. The driven gear 82 is meshed with the limiting tooth plate 16.

[0024] like Figure 8 As shown, the reciprocating component 95 is generally elliptical or rectangular, and upper teeth 951 and lower teeth 952 are provided on opposite inner surfaces of the reciprocating component 95. The driving tooth 94 meshes with the upper teeth 951 or the lower teeth 952.

[0025] It should be noted that a sliding groove is provided on the inner side of the feed shell 6, and the roller 81 can slide in the sliding groove. At the same time, the roller 81 can also rotate in the sliding groove.

[0026] Specifically, the aggregate is fed into the upper part of the feed shell 6 by a conveying mechanism or manually. At this time, the aggregate is located above the crushing roller 7 and the tilting roller 8. The servo motor 91 starts and drives the drive column 92 to rotate, which in turn drives the transmission belt 93 to drive the crushing roller 7 to rotate counterclockwise. With the cooperation of the tilting roller 8, the crushing roller 7 can pre-crush the aggregate. This crushing force is relatively small and can knock on the surface of the aggregate, which makes it easier for the impurities adhering to the aggregate to be separated from the surface of the aggregate, which is convenient for subsequent cleaning of floating and overflowing impurities and improves the purity of the aggregate. At the same time, the rotation of the drive column 92 can drive the drive tooth 94 to rotate. When the drive tooth 94 meshes with the upper tooth 951... When the drive gear 94 continues to rotate, it can drive the connecting piece 96 to move to the left, which in turn drives the tilting roller 8 to move to the left, increasing the distance between the tilting roller 8 and the crushing roller 7. At the same time, the driven gear 82 meshes with the limiting tooth plate 16, causing the tilting roller 8 to rotate clockwise. This can cooperate with the crushing roller 7 to prevent aggregate from getting stuck on the upper end of the tilting roller 8 and the crushing roller 7, and also allow large aggregate to pass through the tilting roller 8 and the crushing roller 7. As the drive gear 94 continues to rotate, when the drive gear 94 meshes with the lower tooth 952, the tilting roller 8 rotates counterclockwise, which reverses the rotation of large aggregate, further preventing aggregate from accumulating and getting stuck, ensuring smooth aggregate conveying, and improving work efficiency.

[0027] like Figures 3-5 As shown, an overflow chamber 11 is provided on the inner side of the lower casing 1, and overflow ports 12 are provided on both sides of the upper end of the lower casing 1. The overflow chamber 11 and the overflow ports 12 are connected. A discharge chamber 13 is provided on the inner side of the lower casing 1 located at the lower end of the overflow chamber 11. A drain channel 14 is also provided at the lower end of the lower casing 1. The drain channel 14 connects the discharge chamber 13 and the circulation tank 4.

[0028] The feeding component 1 2 and the feeding component 2 3 have the same structure. The feeding component 1 2 includes a servo motor 1 21 and a transmission column 22 installed at the output end of the servo motor 1 21. A conveying blade 23 is provided on the outside of the transmission column 22. At least three conveying blades 23 are provided. The feeding component 1 2 and the feeding component 2 3 are matched with the corresponding discharge bin 13. The diameter of the discharge bin 13 corresponding to the feeding component 1 2 is larger than the diameter of the discharge bin 13 corresponding to the feeding component 2 3.

[0029] The water circulation component 5 includes a water pump 51 and an output pipe 52 installed at the output end of the water pump 51. The input end of the water pump 51 is installed at the bottom inside the circulation tank 4. A water pump 51 is installed at the bottom inside the two circulation tanks 4. A water distribution pipe 53 is installed at the output end of the output pipe 52. The water distribution pipe 53 connects the output pipes 52 installed at the output ends of the two water pumps 51. A water outlet pipe 54 is installed at the output end of the water distribution pipe 53. The water outlet pipe 54 is located inside the overflow chamber 11, and the output end of the water outlet pipe 54 is lower than the bottom of the overflow port 12.

[0030] A material distribution block 15 is provided on the lower casing 1 located in the middle of the inner side of the overflow chamber 11. A set of water outlet pipes 54 is provided at the lower inner side of the material distribution block 15, and water outlet pipes 54 discharge water to both sides of the material distribution block 15 at the same time.

[0031] Specifically, after the aggregate falling from the feed tank 6 into the overflow chamber 11, it first falls into the water located inside the overflow chamber 11. Since the water is pumped from the inside of the circulation tank 4 to the inside of the overflow chamber 11 by the water pump 51, and the output end of the water outlet pipe 54 is lower than the bottom of the overflow port 12, the water enters from the water outlet pipe 54 and flows upward from the overflow port 12. In this process, not only is the floating effect of the debris cleverly utilized, but both the debris suspended in the water and the debris attached to the aggregate will be flushed from the bottom up from the overflow port 12 to the inside of the circulation tank 4 by the water, and filtered by the filter screen 41 set at the upper end of the inside of the circulation tank 4. At this time, the water circulation is also completed, and the debris can be cleaned an unlimited number of times. The cleaning effect is significant, and the entire aggregate will be submerged in water, so that the entire aggregate will be wetted, and the surface of the aggregate will be evenly moistened.

[0032] Furthermore, the processed aggregate falls into the bottom of the overflow chamber 11 and between the adjacent conveying blades 23. As the conveying blades 23 are driven to rotate by the servo motor 21, when the adjacent conveying blades 23 carrying aggregate are not connected to the overflow chamber 11, as shown in Figure 4, the cavity formed by the adjacent conveying blades 23 and the discharge chamber 13 is connected to the drainage channel 14, thereby draining the water in the cavity into the circulation tank 4. As the rotation continues, when the adjacent conveying blades 23 carrying aggregate move downwards, the aggregate falls under its own gravity, completing the aggregate discharge without a large amount of water flowing out.

[0033] like Figures 7-8 As shown, a material distribution assembly 10 is also installed at the lower end of the reciprocating component 95. The material distribution assembly 10 includes a connecting plate 101 and a material distribution plate 102 installed at the lower end of the connecting plate 101. A slider 103 is fixedly installed at the lower end of the material distribution plate 102, and the slider 103 is movably connected to the upper end of the material distribution block 15.

[0034] Specifically, the material distribution block 15 divides the overflow chamber 11 into two chambers. When the tilting roller 8 moves to the left, the reciprocating component 95 drives the connecting plate 101, causing the material distribution plate 102 to move to the left. The material distribution plate 102 is triangular in shape when viewed from the side. Large aggregates falling from between the crushing roller 7 and the tilting roller 8 preferentially impact the tip of the material distribution plate 102. This not only facilitates the dispersion of aggregates and prevents clumps of aggregates from trapping debris and making them less likely to be washed away, but also, under the guidance of the triangular material distribution plate 102, large aggregate blocks preferentially fall into the overflow chamber 11 on the right side of the material distribution block 15. At this time, the corresponding discharge chamber 13 has a larger diameter and is controlled by the corresponding large discharge component 12. The output facilitates the output of large aggregates. Similarly, when the reciprocating component 95 moves to the right, the distance between the crushing roller 7 and the tilting roller 8 becomes smaller. At this time, the falling small aggregates are divided by the distribution plate 102 into the overflow chamber 11 on the left side of the distribution block 15, and are output by the corresponding small feeding component 2 3. This method, which avoids clogging by moving the tilting roller 8 left and right, cleverly utilizes the difference in output by moving the tilting roller 8 left and right to maximize the differentiation of aggregate size. It is not only less prone to accumulation and clogging than when conveyed by a single feeding component, but also allows for the preliminary screening of aggregates, so that the output aggregates can be crushed by crushers of different sizes, thus improving the crushing effect.
