Description

Technical Field

[0001] The present invention relates to the technical field of aggregate carbonization, and in particular to a solid waste recycled concrete aggregate carbonization device and process. Background Art

[0002] In the existing technology, a lot of solid waste is always generated during the construction or demolition of buildings, and these solid wastes still have a high recycling value. With the purpose of recycling solid waste, people will carry out a series of treatments on the solid waste, recycle the solid waste into recycled concrete aggregate, mix the recycled concrete aggregate with new concrete, and continue to use the solid waste in the construction industry.

[0003] In the process of using recycled concrete aggregates, because recycled concrete aggregates have higher porosity and water absorption capacity, the concrete produced with them has certain quality differences compared with concrete using conventional aggregates. Carbonation treatment can seal the pores and reduce water absorption by injecting carbon dioxide into the recycled aggregates, thereby improving the density and strength of the concrete. After the recycled concrete aggregates are carbonized, the performance attenuation problem caused by environmental factors during the subsequent use of the recycled concrete aggregates can also be alleviated. Therefore, carbonization treatment of recycled concrete aggregates processed from solid waste is an indispensable process in the practical application of recycled concrete aggregates.

[0004] The prior art generally carbonizes the crushed recycled concrete aggregate by fully mixing carbon dioxide gas, carbonation reaction solution and recycled concrete aggregate, so that the carbon dioxide gas, carbonation reaction solution and recycled concrete aggregate undergo a chemical reaction to complete the carbonization of the recycled concrete aggregate. However, in the actual use of recycled concrete aggregate in real life, the carbonization amount of the recycled concrete aggregate corresponds to the actual amount of recycled concrete aggregate used, so the amount of recycled concrete aggregate required for centralized carbonization each time is not fixed. However, because the carbonization operation is formed by the full reaction between the three substances of gas, solid and liquid, the carbonation reaction solution and carbon dioxide gas need to be used to assist in the carbonization of the concrete aggregate. The concrete aggregate, the carbonation reaction solution and the carbon dioxide gas need to be fully mixed. However, when there are fewer recycled concrete aggregates to be carbonized, if a larger carbonization treatment area is still selected to operate the concrete aggregate, the carbonation reaction solution and the carbon dioxide gas, it is inevitable that there will be a waste problem caused by excessive use of carbonization resources.

[0019] A solid waste recycled concrete aggregate carbonization process, using the above-mentioned solid waste recycled concrete aggregate carbonization device, comprises the following steps:

[0020] Step 1, adding aggregate: adding concrete aggregate into the conveying cylinder, and then starting the first driving motor to drive the spiral conveying rod to rotate, so that the concrete aggregate moves in the conveying cylinder, and finally the concrete aggregate is discharged through the discharge port;

[0021] Step 2, adding reaction solution: adding carbonization reaction solution into the communicating cylinder through the liquid adding pipe, allowing the carbonization reaction solution to enter the plurality of liquid supply pipes, and allowing the carbonization reaction solution to be discharged through the liquid discharge pipe located in the mixing cylinder;

[0022] Step 3, move the sliding sealing plate: drive the sliding sealing plate to move within the mixing cylinder, adjust the area of ​​the carbonization region within the mixing cylinder, and during the movement of the sliding sealing plate, drive the conveying cylinder, one of the fixed shafts and the two sliding members to move together. During the movement of the sliding sealing plate and one of the fixed shafts, under the action of the spring damper, the sliding rod will slide within the telescopic sleeve, push the two sliding rings to move to the two sides of the rotating sleeve, and then as the sliding sealing plate continues to unfold, the sliding rod will also slide within the sliding sleeve. After the sliding sealing plate has moved, the positions of the stirring frame 1 and the stirring frame 2 also stop moving, and the sliding member and the transmission wheel will also slide in the sliding frame, and the transmission wheel will adjust the deployment area of ​​the gas pipeline in the sliding frame, so that the gas pipeline as a whole is located on the upper side of the carbonization area of ​​the mixing cylinder. During the movement of the gas pipeline, the dual-axis motor is started to drive the two winding cylinders to rotate in their respective corresponding rotating frames, so that the winding cylinder reels or unwinds the traction rope, so that the gas pipeline maintains tension;

[0023] Step 4, mixing aggregate and solution: starting the second driving motor to drive the fixed shaft disposed on the mixing cylinder to rotate, so that the rotating sleeve and the two fixed shafts rotate together, so that the rotating sleeve and the fixed shaft respectively drive the stirring frame 1 and the stirring frame 2 to rotate, so that the stirring frame 1 and the stirring frame 2 mix the concrete aggregate and the carbonization reaction solution in the carbonization area;

[0024] Step 5, filling gas: extracting carbon dioxide gas through the gas transmission equipment, and then transmitting it to the gas transmission pipeline, starting the third drive motor to drive the rotating shaft to rotate, so that the offset frame flips along the center point of the rotating shaft, so that the offset frame contacts the hose section of the gas filling pipe, driving the gas filling pipe to move downward, so that the hard pipe section of the gas filling pipe enters the concrete slurry, so that the carbon dioxide gas is finally discharged through the gas filling pipe, and the carbon dioxide gas enters the concrete slurry;

[0025] Step 6, carbonization treatment: continue to use the third drive motor, the rotating shaft and the offset frame to cooperate, drive the soft tube section of the gas adding pipe to bend, so that the hard tube section is moved out of the concrete slurry, and then continue to mix the concrete slurry after the gas is added through the plurality of the first stirring racks and the second stirring racks to complete the carbonization operation of the concrete aggregate;

[0026] Step seven, discharging concrete aggregate: starting the driving electric cylinder to drive the rotating shaft to move, so that the closed bottom plate is moved out of the discharge port, so that the concrete aggregate slurry flows into the sloped discharge channel along the top wall of the closed bottom plate, and flows along the inclined inner bottom wall of the sloped discharge channel, so that the concrete slurry is discharged from the sloped discharge channel.

[0027] The working principle and beneficial effects of the present invention are:

[0028] 1. In the present invention, when it is necessary to perform carbonization operation on recycled concrete aggregate, when the carbonization amount of recycled concrete aggregate is small, in order to avoid a large amount of idle space inside the mixing cylinder when carbonization operation is performed on a small amount of recycled concrete aggregate, the sliding cover plate is driven to move, so that the sliding cover plate adjusts the area in the mixing cylinder for mixing the recycled concrete aggregate and the carbonization reaction solution, and then in the process of using the spiral feeding structure to add concrete aggregate into the mixing cylinder, the carbonization reaction solution can be synchronously added into the mixing cylinder through the liquid adding component to mix the concrete aggregate and the carbonization reaction solution. In the present application, the spiral feeding structure can be driven to move synchronously by the movement of the sliding cover plate, so the spiral feeding structure can be adjusted during the movement of the sliding cover plate. The structure sets the discharge position of the aggregate so that the aggregate is discharged from one side of the mixing cylinder to the other side following the movement of the sliding cover plate, and the discharge position of the liquid adding component for the carbonization reaction solution can also correspond to the discharge position of the aggregate, so that the liquid adding component area entering the mixing cylinder discharges the carbonization reaction solution, so that the aggregate and the carbonization reaction solution are initially in contact with each other during the initial discharge process, and the stirring area of ​​the mixing cylinder by the telescopic stirring mechanism corresponds to the distance between the sliding cover plate and the inner wall of the mixing cylinder, so when a small amount of concrete aggregate is carbonized, the sliding cover plate can be moved to reduce the carbonization area between the sliding cover plate and the inner wall of the mixing cylinder, so that various resources used to complete the carbonization operation of the recycled concrete are fully utilized;

[0029] 2. In the present invention, in order to improve the efficiency of the carbonization operation of concrete aggregates after reducing the area of ​​the carbonization operation of concrete aggregates inside the mixing cylinder, the sliding sealing plate is driven to move in the mixing cylinder, so that the sliding sealing plate adjusts the position of the gas pipeline in the sliding frame, so that the gas pipeline and multiple gas adding pipes are located in the carbonization area between the sliding frame and the sliding sealing plate, thereby further improving the carbonization efficiency of a small amount of concrete aggregates under the premise of reducing the carbonization area in the mixing cylinder;

[0030] 3. Therefore, during the carbonization process of a small amount of concrete aggregate, the solid waste recycled concrete aggregate carbonization device reduces the carbonization treatment area in the mixing cylinder, so that a small amount of concrete aggregate can also be fully carbonized without wasting excess carbonization resources. When the processing amount of concrete aggregate is small, the carbonization speed of concrete aggregate can also be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Embodiment 1, as Figures 1 to 12 As shown, this embodiment proposes a solid waste recycled concrete aggregate carbonization device, including a mixing cylinder 1, and also includes a sliding sealing plate 2, the sliding sealing plate 2 is slidably arranged in the mixing cylinder 1, the top of the mixing cylinder 1 is rotatably connected with a transmission screw 42, the sliding sealing plate 2 is threadedly connected to the transmission screw 42, and a motor driving device 43 is arranged on the top of the mixing cylinder 1, and the output end of the motor driving device 43 is fixedly connected to the transmission screw 42. When it is necessary to drive the sliding sealing plate 2 and the two sliding members 23 to move laterally, the motor driving device 43 is started to drive the transmission screw 42 to rotate, so that the sliding sealing plate 2 and the two sliding members 23 move laterally, and the sliding sealing plate 2 moves in the mixing cylinder 1, and the area inside the mixing cylinder 1 for carbonizing the recycled concrete aggregate is adjusted;

[0048] A through-slide is provided on one side of the mixing cylinder 1, and a spiral injection structure 100 is slidably provided in the through-slide. The spiral injection structure 100 includes a conveying cylinder 4, a spiral conveying rod 5 and a first drive motor 6. The conveying cylinder 4 is slidably connected in the through-slide, one end of the conveying cylinder 4 is fixedly connected to the sliding sealing plate 2, and a discharge port is provided at one end of the conveying cylinder 4 close to the sliding sealing plate 2. The conveying cylinder 4 is rotatably connected with the spiral conveying rod 5. The first drive motor 6 is provided on the conveying cylinder 4, and the output end of the first drive motor 6 is fixedly connected to the spiral conveying rod 5. When it is necessary to add material to the inside of the mixing cylinder 1 When pouring concrete aggregate, firstly, the concrete aggregate is input into the conveying cylinder 4 through the feed port opened on the conveying cylinder 4, and the first driving motor 6 is started to drive the spiral conveying rod 5 to rotate, so that the concrete aggregate moves in the conveying cylinder 4, and finally the concrete aggregate is discharged through the discharge port, and in the process of the movement of the sliding cover plate 2, the conveying cylinder 4 will be driven to move with the sliding cover plate 2, so that the concrete aggregate discharged through the discharge port will be evenly distributed in the carbonization area set in the sliding cover plate 2 and the mixing cylinder 1, so that the concrete aggregate is evenly added to the carbonization area in the mixing cylinder 1.

[0049] like Figures 1 to 8 As shown, the spiral injection structure 100 is fixedly connected to the sliding sealing plate 2, and a telescopic stirring mechanism 300 is arranged between the end of the sliding sealing plate 2 close to the spiral injection structure 100 and the inner wall of the mixing cylinder 1, and the telescopic stirring mechanism 300 includes a fixed shaft 11, a rotating sleeve 12, a second drive motor 13, a stirring frame 14, a stirring frame 2 and a telescopic adjustment component. The sliding sealing plate 2 and the inner wall of the mixing cylinder 1 close to the conveying cylinder 4 are both rotatably connected with the fixed shaft 11, and a rotating sleeve 12 is slidably sleeved between the two fixed shafts 11. The second drive motor 13 is arranged on the outer wall of the mixing cylinder 1, and the output end of the second drive motor 13 is fixedly connected to one of the fixed shafts 11. A plurality of stirring frames 14 are fixedly connected to the circumference of the fixed shaft 11, and the rotating sleeve 1 2 is slidably connected with a sliding ring 16 on both sides, and a plurality of stirring racks 15 are fixedly connected to the sliding ring 16 on the circumference. There is a one-to-one correspondence between the stirring racks 14 and the stirring racks 15, and a telescopic adjustment component is arranged between the two stirring racks 14 and the two stirring racks 15 on the same side in the lateral direction. After the concrete aggregate and the carbonization reaction solution are added into the carbonization area in the mixing cylinder 1, the second driving motor 13 is started to drive the fixed shaft 11 arranged on the mixing cylinder 1 to rotate, so that the rotating sleeve 12 and the two fixed shafts 11 rotate together, so that the rotating sleeve 12 and the fixed shaft 11 respectively drive the stirring rack 14 and the stirring rack 15 to rotate, so that the stirring rack 14 and the stirring rack 15 fully mix the concrete aggregate and the carbonization reaction solution in the carbonization area;

[0050] The telescopic adjustment component includes a sliding sleeve 17 and a telescopic sleeve 19. The opposite ends of the two stirring racks 15 are fixedly connected with the sliding sleeve 17. The stirring rack 14 is fixedly connected with a sliding rod 18, and the sliding rod 18 is slidably connected in the sliding sleeve 17. One of the stirring racks 15 is fixedly connected with the telescopic sleeve 19, and the other stirring rack 15 is fixedly connected with a sliding rod 20, and the sliding rod 20 is slidably connected in the telescopic sleeve 19. A spring damper 21 is arranged between the sliding rod 20 and the inner wall of the telescopic sleeve 19. When the sliding sealing plate 2 is used to adjust the carbonization area inside the mixing cylinder 1, the corresponding stirring racks 14 and 15 will move away from each other. The sliding rod 18 slides in the sliding sleeve 17, so that the sliding rod 18 and the sliding sleeve 17 can adapt to the distance between the stirring rack 14 and the stirring rack 2, and When the slide bar 18 and the sliding sleeve 17 rotate with the fixed shaft 11 and the rotating sleeve 12, the slide bar 18 and the sliding sleeve 17 can also mix the concrete aggregate and the carbonization reaction solution in the carbonization area. The larger the distance between the stirring frame 14 and the stirring frame 2 15, the larger the expansion area between the slide bar 18 and the sliding sleeve 17, and the larger the mixing range of the slide bar 18 and the sliding sleeve 17. Regardless of whether the carbonization area is increased or decreased, the stirring frame 14, the stirring frame 2 15, the slide bar 18 and the sliding sleeve 17 used in the present application can fully mix the concrete aggregate and the carbonization reaction solution. Compared with the problem in the prior art that a small amount of concrete aggregate and carbonization reaction solution are added to a larger mixing device, many areas of the mixing device are idle, the present application can make full use of the mixing components;

The bottom end of the hard pipe section 29 is connected with a plurality of exhaust holes. When it is necessary to add carbon dioxide gas to the concrete slurry, the hard pipe section 29 of the gas filling pipe 27 is firstly extended into the concrete slurry, so that the carbon dioxide gas is discharged through the gas filling pipe 27, and the gas is mixed with the concrete slurry.

[0056] Both sides of the mixing cylinder 1 are provided with an offset structure for driving the gas filling pipe 27 to offset, and the offset structure includes a mounting groove 34, a third drive motor 36 and an offset frame 37.

[0058] Working principle of the solid waste recycled concrete aggregate carbonization device:

[0059] First, concrete aggregate is added into the conveying cylinder 4, and then the first driving motor 6 is started to drive the spiral conveying rod 5 to rotate, so that the concrete aggregate moves in the conveying cylinder 4, and finally the concrete aggregate is discharged through the discharge port, and the sliding sealing plate 2 is driven to move laterally in the mixing cylinder 1, so that the conveying cylinder 4 follows the movement of the sliding sealing plate 2, and the concrete aggregate is evenly added into the carbonization area in the mixing cylinder 1. In the process of concrete aggregate filling, the carbonization reaction solution is added into the connecting cylinder 9 through the liquid filling pipe 10, so that the carbonization reaction solution enters into the multiple liquid supply pipes 7, and each liquid discharge pipe 8 is provided with a valve. By adjusting the opening and closing of the valve, the carbonization reaction solution is discharged only through the liquid discharge pipe 8 located in the mixing cylinder 1. Because the conveying cylinder 4 will move with the sliding sealing plate 2 during the discharge process, the multiple liquid supply pipes 7 will also move with the conveying cylinder 4, so that the carbonization reaction solution and the concrete aggregate are evenly distributed in the carbonization area in the mixing cylinder 1.

[0060] During the movement of the sliding cover plate 2, firstly, under the action of the spring damper 21, the sliding rod 20 will slide in the telescopic sleeve 19, pushing the two sliding rings 16 to move to the two sides of the rotating sleeve 12, and then as the sliding cover plate 2 continues to unfold, the sliding rod 18 will also slide in the sliding sleeve 17. After the sliding cover plate 2 is moved, the positions of the stirring frame 14 and the stirring frame 2 15 also stop moving, and the second driving motor 13 is started to drive the fixed shaft 11 set on the mixing cylinder 1 to rotate, so that the rotating sleeve 12 and the two fixed shafts 11 rotate together, so that the rotating sleeve 12 and the fixed shaft 11 respectively drive the stirring frame 14 and the stirring frame 2 15 to rotate, so that the stirring frame 14 and the stirring frame 2 15 can fully mix the concrete aggregate and the carbonization reaction solution in the carbonization area;

[0061] During the movement of the sliding cover plate 2, the sliding cover plate 2 will drive the sliding member 23 and the transmission wheel 26 to move together, and the transmission wheel 26 will adjust the expansion area of ​​the gas pipeline 25 in the sliding frame 22, so that the gas pipeline 25 is located on the upper side of the carbonization area of ​​the mixing cylinder 1 as a whole. During the movement of the gas pipeline 25, the dual-axis motor 33 is started to drive the two winding cylinders 31 to rotate in their respective corresponding rotating frames 30, so that the winding cylinder 31 winds or unwinds the traction rope 32, so that the conveying pipeline remains stable during the movement and the subsequent transportation of carbon dioxide gas, and the hard pipe section 29 of the gas filling pipe 27 enters the mixed concrete slurry, and the gas transmission equipment 24 is used to The carbon dioxide gas is extracted and then transported to the gas transmission pipeline 25, so that the carbon dioxide gas is finally discharged through the gas filling pipe 27, so that the carbon dioxide gas enters the concrete slurry, and then the third driving motor 36 is started to drive the rotating shaft 35 to rotate, so that the offset frame 37 is turned along the center point of the rotating shaft 35, so that the offset frame 37 contacts the hose section 28 of the gas filling pipe 27, drives the hose section 28 of the gas filling pipe 27 to bend, and the hard pipe section 29 of the gas filling pipe 27 moves upward, so that the gas filling pipe 27 is removed from the concrete slurry, and then the concrete slurry after the gas is fully mixed by the multiple mixing racks 1 14 and the multiple mixing racks 2 15, so as to complete the carbonization operation of the concrete aggregate;

[0062] After the carbonization operation of the concrete aggregate is completed, the driving electric cylinder 41 is started to drive the rotating shaft 40 to move, so that the closed bottom plate 38 is flipped along the center point of the hinge, and the closed bottom plate 38 is moved out of the discharge port, so that the concrete aggregate slurry flows along the top wall of the closed bottom plate 38 into the sloped discharge channel 3, and flows along the inclined inner bottom wall of the sloped discharge channel 3, so that the concrete slurry is discharged from the sloped discharge channel 3.

[0069] Step 6, carbonization treatment: continue to use the third drive motor 36, the rotating shaft 35 and the offset frame 37 to cooperate, drive the hose section 28 of the gas adding pipe 27 to bend, so that the hard pipe section 29 is moved out of the concrete slurry, and then continue to mix the concrete slurry after the gas is added through the multiple mixing racks 14 and the multiple mixing racks 2 15 to complete the carbonization operation of the concrete aggregate;

[0070] Step 7, discharging concrete aggregate: start the driving electric cylinder 41 to drive the rotating shaft 40 to move, so that the closed bottom plate 38 is moved out of the discharge port, so that the concrete aggregate slurry flows along the top wall of the closed bottom plate 38 into the sloped discharge channel 3, and flows along the inclined inner bottom wall of the sloped discharge channel 3, so that the concrete slurry is discharged from the sloped discharge channel 3.
