Description

Technical Field

[0001] The present application relates to the technical field of recycled aggregate processing, and in particular to a device for carbon fixation microorganism enhanced recycled aggregate and an aggregate regeneration method. Background Art

[0002] Aggregates made from waste concrete are called recycled concrete aggregates (recycled aggregates for short). Recycled aggregates made through simple crushing and screening processes have many edges and corners, rough surfaces, and contain hardened cement mortar. In addition, the concrete blocks accumulate damage during the crushing process, causing a large number of microcracks inside. This results in large porosity, high water absorption, small packing density, large void ratio, and high crushing index.

[0003] At present, the methods for enhancing the performance of recycled aggregates mainly include physical crushing and chemical treatment, such as injecting chemical admixtures after mechanical crushing to improve the physical structure and chemical stability of aggregates. Although these methods can improve the performance of recycled aggregates to a certain extent, the size of the crushed aggregates is different, which makes the injection effect of chemical admixtures different, reducing the treatment effect and efficiency, making the treatment accompanied by high energy consumption and high cost, and may also produce harmful environmental emissions. Summary of the invention

[0035] The feed pipe 24 is fixedly mounted on the upper surface of the screening cover 25, and the feed pipe 24 is connected to the screening kettle 21. The feed pipe 24 is used to transport the aggregate to be screened and add it to the screen 23 located at the highest point. The vibration assembly 3 is arranged on the connecting frame 27 and is used to vibrate the screen frame 22. The vibration assembly 3 includes a vibration motor 31 and a plurality of springs 32. The vibration motor 31 is mounted on the connecting frame 27, and the vibration motor 31 is started to vibrate the connecting frame 27, the screen frame 22 and the plurality of screens 23. The plurality of springs 32 are arranged in a circular array around the axis of the screening kettle 21. The bottom end of the spring 32 is fixedly mounted on the upper surface of the mounting ring 28 and the top end is fixedly mounted on the lower surface of the connecting frame 27, so as to achieve buffering when the connecting frame 27 and the screen 23 vibrate.

[0036] The multiple screens 23 vibrate to screen the aggregates. Aggregates with too large a particle size are located on the highest screen 23, while aggregates with too small a particle size fall through the lowest screen 23. Aggregates on other screens 23 have a particle size that is suitable for processing. Aggregates with suitable particle sizes are placed on screens 23 at different heights according to their particle sizes, and the aggregate particle size on the screen 23 gradually decreases from top to bottom.

[0037] Reference Figure 2 and Figure 3The collecting assembly 4 is used to collect different aggregates. The collecting assembly 4 includes a collecting pipe, a conveying pipe 41, a plurality of partition plates 42 and a bottom bucket 43. One end of the collecting pipe is fixedly mounted on the side wall of the screening kettle 21 and is located close to the top side of the screening kettle 21. The other end of the collecting pipe is tilted downward and is used to output the aggregate located on the highest screen 23. One end of the feed pipe 41 is fixedly installed on the side wall of the screening kettle 21, and the other end of the feed pipe 41 is inclined downward and connected to the outer wall of the kettle body 1. The connection between the feed pipe 41 and the kettle body 1 is located at the top of the kettle body 1 and is connected to the inside of the kettle body 1. The cross-sections of both ends of the feed pipe 41 are quadrilateral and the area close to the screening kettle 21 is larger than the area close to the kettle body 1. A plurality of partition plates 42 are vertically spaced and fixedly installed on the inner wall of the feed pipe 41, and the plurality of partition plates 42 divide the feed pipe 41 into a plurality of channels 44. The plurality of screens 23 located below the highest screen 23 are arranged one by one corresponding to the plurality of channels 44, and the aggregate located on the screen 23 is input into the kettle body 1 through the corresponding channels 44.

[0038] The bottom bucket 43 is placed at the bottom of the screening kettle 21, and the bottom bucket 43 is used to receive the aggregate passing through the screen 23 located at the lowest point; a discharge component for controlling the opening and closing of the collecting pipe is provided on the collecting pipe, and a plurality of discharge components for controlling the opening and closing of a plurality of channels 44 are also provided on the conveying pipe 41. The following is an explanation taking the discharge component located on the collecting pipe as an example.

[0039] The discharge assembly includes a discharge door and a discharge piece. The discharge door is slidably installed on the collecting pipe and is used to block or open the collecting pipe. The discharge piece is a cylinder or an electric push rod. The discharge piece is fixedly installed on the collecting pipe and is used to drive the discharge door to move. When the discharge piece starts to drive the discharge door to open, the aggregate located on the highest screen 23 is output through the collecting pipe, and the feed pipe 41 also operates in the same way. When the aggregate of the required particle size needs to be discharged, the corresponding channel 44 is opened, so that the aggregate of the required particle size is input through the channel 44 and added to the kettle body 1.

[0040] Reference Figure 2 and Figure 4 The processing mechanism 5 includes a plurality of supporting meshes 51, which are vertically spaced and arranged in the kettle body 1 through an adjusting component 6, the number of the supporting meshes 51 is one less than the number of the screens 23, and the adjusting component 6 is located on the side of the supporting meshes 51 away from the feed pipe 41; the supporting meshes 51 are each provided with a plurality of mesh holes for liquid to pass through, and the aggregate is transported and added to the plurality of supporting meshes 51 through a plurality of channels 44, and the particle size of the aggregate located on the plurality of supporting meshes 51 gradually increases from top to bottom.

[0041] The adjustment component 6 makes the support mesh 51 horizontal for placing aggregates, or makes the support mesh 51 close to the feed pipe 41 tilted, so as to facilitate the aggregates on the support mesh 51 to fall off.

[0042] When it is necessary to transport and add aggregate to the support mesh 51, the support mesh 51 located at the lowest position is turned to a horizontal state, and the multiple support meshes 51 located above this support mesh 51 are turned to an inclined state, and then the aggregate with the largest particle size is added to the kettle body 1 through the channel 44, and the aggregate enters the kettle body 1 and falls downward onto the horizontal support mesh 51. At the same time, after falling onto the support mesh 51 located above, it will roll down to the horizontal support mesh 51 under the action of gravity, thereby adding the aggregate with the largest particle size to the support mesh 51 located at the lowest position, and then continue to repeat from bottom to top to add aggregates of different particle sizes to the support meshes 51 at different heights, so that the particle size of the aggregate on the support mesh 51 gradually increases from top to bottom.

[0043] Reference Figure 4 and Figure 5 The adjusting assembly 6 includes an adjusting block 61, an adjusting member 62, a moving block 63 and a supporting rod 64. The adjusting block 61 is fixedly mounted on the inner wall of the kettle body 1 and is in a vertical state; the supporting mesh 51 is rotatably mounted on the adjusting block 61, and a placement hole is provided for placing the adjusting block 61. A vertical adjusting groove 65 is provided at the bottom of the adjusting block 61. The adjusting member 62 is an electric push rod. The cylinder body of the adjusting member 62 is fixedly mounted in the adjusting groove 65 for protection, which reduces the damage of the adjusting member 62 to the liquid, and the piston rod of the adjusting member 62 extends vertically downward to the bottom of the supporting mesh 51. The moving block 63 is fixedly mounted on the piston rod of the adjusting member 62 and abuts against the inner wall of the kettle body 1 for support and positioning; the two ends of the supporting rod 64 are rotatably connected to the center of the lower surface of the supporting mesh 51 and the moving block 63 respectively.

[0044] The piston rod of the adjusting member 62 moves to drive the moving block 63 to move, and the moving block 63 moves through the supporting rod 64 to drive the supporting mesh 51 to rotate, so that the supporting mesh 51 is in a horizontal or inclined state; at the same time, the adjusting member 62 can also continue to perform a small range of reciprocating micro-motion, so that the supporting mesh 51 vibrates, so that the aggregate added to the supporting mesh 51 is spread flat on the supporting mesh 51, thereby facilitating the subsequent processing of the aggregate.

[0045] A heating mechanism for heating is arranged on the kettle body 1, and the heating mechanism comprises a heater and a temperature controller. The heater is wrapped on the outer wall of the kettle body 1 and is used to heat the kettle body 1. The temperature controller is fixedly mounted on the inner wall of the kettle body 1, and the temperature controller is used to detect the temperature inside the kettle body 1. At the same time, the temperature controller is used to control the start and stop of the heater, so that the kettle body 1 is at a suitable temperature, so that the aggregate is at a suitable temperature during processing, thereby improving the processing efficiency and effect of the aggregate.

[0046] Reference Figure 1The processing mechanism 5 also includes an exhaust and air intake component 7, a spray component 8 and a discharge component 9. The exhaust and air intake component 7 is used to first evacuate the kettle body 1 and then introduce carbon dioxide gas; the exhaust and air intake component 7 includes an exhaust pump 71, a gas cylinder 72 and an injection pipe 73. The top of the kettle body 1 is in an open state and a kettle cover 74 for sealing the opening is detachably installed through a screw nut. The exhaust pump 71 is placed on the ground and is fixedly installed with an exhaust pipe 75 fixedly connected to the upper surface of the kettle cover 74. The exhaust pipe 75 is connected to the kettle body 1 and is fixedly installed with an exhaust valve 76 for controlling the opening and closing. When the exhaust valve 76 is opened, the exhaust pump 71 starts to extract the air in the kettle body 1, so as to achieve vacuuming of the kettle body 1. After the vacuuming is completed, the exhaust valve 76 is closed.

[0047] The gas cylinder 72 is filled with carbon dioxide gas, and the injection pipe 73 is fixedly installed on the upper surface of the gas cylinder 72 and the kettle cover 74. The injection pipe 73 is connected to the kettle body 1 and is fixedly installed with a pressure gauge 78 for detecting the air pressure in the gas cylinder 72. At the same time, a control valve 77 for controlling the opening and closing is fixedly installed on the injection pipe 73, and the pressure gauge 78 is located between the control valve 77 and the gas cylinder 72. When the kettle body 1 is evacuated, the exhaust valve 76 is closed and the control valve 77 is opened, and the carbon dioxide gas in the gas cylinder 72 is input through the injection pipe 73 and added to the kettle body 1. At the same time, an air pressure safety valve is fixedly installed on the kettle cover 74, and the pressure is released when the air pressure in the kettle body 1 is greater than a specified value.

[0048] Reference Figure 1 and Figure 4 The spray assembly 8 is used to spray the treatment liquid into the kettle body 1. The spray assembly 8 includes a liquid storage barrel 81, a spray pump 82 and a spray plate 83. The liquid storage barrel 81 is placed on the ground and is used to hold the treatment liquid. The treatment liquid is a microbial liquid or a mineralized melt such as a calcium salt melt. The cell wall of the treatment liquid can absorb calcium ions in the aggregate. At the same time, carbon dioxide combines with calcium ions to form calcium carbonate. The calcium carbonate is deposited in the pores on the surface of the recycled aggregate, thereby blocking the pores on the surface of the recycled aggregate and enhancing the performance of the recycled aggregate.

[0049] The spray pump 82 is connected to the liquid storage barrel 81, the spray plate 83 is fixedly installed on the lower surface of the kettle cover 74, and a plurality of spray holes are evenly opened on the lower surface of the spray plate 83. A spray pipe 84 fixedly connected to the spray plate 83 is fixedly installed on the spray pump 82, and the spray pipe 84 is connected to the plurality of spray holes. When the spray pump 82 is started, the treatment liquid in the liquid storage barrel 81 is evenly sprayed onto the aggregate through the plurality of spray holes.

[0050] The aggregate particle size on the highest support mesh 51 is the smallest, so the treatment liquid sprayed through the spray hole can easily enter the aggregate for treatment. As the treatment liquid flows, the aggregate particle size below gradually increases. However, after the treatment liquid gathers in the kettle body 1, it can soak the aggregate below, thereby improving the treatment efficiency and effect of the aggregate.

The discharge assembly 9 includes a liquid discharge pipe 91, a discharge pipe 92, a waste liquid bucket 93 and a collecting box 94. The liquid discharge pipe 91 is fixedly installed at the bottom of the discharge portion 12, and the liquid discharge pipe 91 is connected with the inside of the discharge portion 12 and a filter plate is fixedly installed at the connection point, and the filter plate is used to block the passage of aggregate and allow liquid to pass through; the discharge pipe 92 is fixedly installed at the bottom of the discharge portion 12, and the connection between the discharge pipe 92 and the kettle body 1 is located below the connection between the discharge pipe 91 and the kettle body 1, and the discharge pipe 92 is used to discharge aggregate. A discharge valve 97 for controlling opening and closing is fixedly installed on the discharge pipe 92, and a liquid discharge valve 96 for controlling opening and closing is fixedly installed on the discharge pipe 91.

[0052] The waste liquid barrel 93 is connected to the bottom of the liquid outlet pipe 91 and is used to collect the outflowing waste liquid. The waste liquid barrel 93 can also be connected to the liquid storage barrel 81 through the return pipe 95, so that the treated waste liquid can flow into the liquid storage barrel 81 for recycling and reuse; the collection box 94 is located below the discharge pipe 92 and is used to collect aggregates.

[0053] The working principle of the embodiment of the present application is as follows: Aggregate is added to the highest screen 23 through the feed pipe 24, and the vibration motor 31 is started to vibrate the multiple screens 23 to screen the aggregate to obtain aggregate with appropriate particle size, and aggregates of different particle sizes are located on the screens 23 at different heights, and then the channel 44 is opened to add aggregate to the multiple support meshes 51, and the aggregate particle size located on the support meshes 51 gradually increases from top to bottom, and the channel 44 is closed after the addition is completed; the vacuum pump 71 is started to vacuum the kettle body 1, so that the gas in the kettle body 1 and in the gaps of the aggregates is exhausted, and then the control valve 77 is opened, and the gas is discharged. The carbon dioxide gas in the bottle 72 is added into the kettle body 1, and the carbon dioxide gas will enter the gaps in the aggregate. The spray pump 82 is started to spray the treatment liquid onto the aggregate through the spray hole. The cell wall of the treatment liquid can absorb calcium ions in the aggregate. At the same time, carbon dioxide combines with calcium ions to form calcium carbonate, which is deposited in the pores on the surface of the recycled aggregate, thereby blocking the pores on the surface of the recycled aggregate and strengthening the performance of the recycled aggregate, thereby improving the processing efficiency and effect of the aggregate. At the same time, it can also consume carbon dioxide gas in the environment, reduce energy consumption and cost in the processing process, and also reduce the emission of harmful emissions.
