Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, in particular to a construction waste pool capable of absorbing carbon dioxide, and also to a method for using the construction waste pool capable of absorbing carbon dioxide. Background Art

[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and stones and other wastes generated by people in the production activities of the construction industry such as demolition, construction, decoration and repair. Many wastes in construction waste can be reused as renewable resources after sorting, removal or crushing, such as waste steel bars, waste iron wires, waste wires and various waste steel accessories. Metals can replace sand and be used for masonry mortar, plastering mortar, concrete cushion, etc., and can also be used to make building blocks, paving bricks, lattice bricks and other building materials.

[0003] The coarse and fine aggregates produced from waste construction concrete and waste bricks and stones can be used to produce concrete and mortar of corresponding strength grades or to prepare building materials such as blocks, wall panels, and floor tiles. After adding curing materials, the coarse and fine aggregates can also be used for highway pavement base.

[0004] At the same time, cement plants, thermal power plants, and steel mills will emit a large amount of high-concentration carbon dioxide. If this high-concentration carbon dioxide is directly discharged into the atmosphere without treatment, it will cause a certain degree of environmental pollution. Therefore, it is necessary to combine high-concentration carbon dioxide with concrete carbon strengthening and construction waste utilization, so as to achieve the combination of waste resource utilization and environmental resource protection, improve quality and efficiency. Therefore, a construction waste pool that can absorb carbon dioxide and a method of using it are needed. Summary of the invention

The original construction waste pool can be transformed and a reinforced bottom pool and a recycled aggregate storage pool can be added to achieve the crushing and strengthening of discarded construction concrete and building bricks and stones in the construction waste, forming reusable reinforced recycled aggregates. At the same time, it can also be used as the original construction waste pool, so that one pool can be used for two purposes, greatly saving the installation space required for recycled concrete, and improving the recycling rate of construction waste and the quality of the prepared recycled concrete.

[0016] Preferably, the storage pool part is composed of a storage pool body as the main body. The garbage pool bottom plate at the bottom of the storage pool body is a fully enclosed structure, and several rubber buffer pads are provided on the garbage pool bottom plate of the storage pool body to catch the falling recycled and strengthened concrete.

[0017] Correspondingly, the present invention also provides a use method for the construction waste pool capable of absorbing carbon dioxide, and its steps are as follows:

[0018] S1. Storage and preliminary crushing and unloading: When the garbage pool is used as an ordinary garbage pool to store various construction wastes, the gear on it is controlled by the first stepper motor to rotate on the first rack track, so that the first floor plate is moved to the innermost side of the first slot, so as to close the bottom of the garbage pool body, and then the internal closure of the entire garbage pool is achieved, and it can be used as an ordinary garbage pool; when the garbage pool is used as a garbage pool for recycling and strengthening waste concrete and building masonry, the gear on it is controlled by the first stepper motor to rotate on the first rack track, so that the first floor plate is moved out of the inner side of the first slot, and the second floor plate is moved to the innermost side of the second slot, so that the bottom of the garbage pool body is formed by the second layer with a screen opening. The bottom plate is a closed bottom plate, and construction waste can be poured into the garbage pool from the entrance. After completion, the crushing track lifting plate is lowered to a suitable height by the first electric push rod, and the pneumatic hammer is started for preliminary crushing. At the same time, the electric trolley at the bottom of the pneumatic hammer is controlled to move back and forth on the crushing track to achieve all-round coverage and crushing inside the box. After the concrete waste is crushed to a suitable size, the crushing can be stopped. After the crushing is completed, the gear on it can be controlled by the first stepper motor to rotate on the first rack track, so that the second-layer bottom plate is also moved out of the second-layer slot, so that the construction concrete waste that has been initially crushed on the second-layer bottom plate falls into the middle opening of the garbage pool bottom plate, and then falls into the funnel unloading plate for the next step;

[0019] S2. Secondary crushing and strengthening: After the primary crushing of the main garbage pool is completed, the concrete waste falls into the hopper discharge plate, then slides into the discharge port, and then enters the jaw crusher of the secondary crushing unit through the discharge port for crushing. At this time, the transfer unit is controlled to move on the first transport track to the bottom of the jaw crusher's discharge port, and the crushed aggregate falls into the box body from the top of the transport box to the left through the jaw crusher's discharge track. After a sufficient amount of crushed concrete is stored, the discharge is stopped, and the transfer unit is moved to the lime water strengthening unit on the first transport track. At this time, the lime water strengthening box is lowered to a suitable height by the third electric push rod on it, and the second electric push rod mounting plate is rotated by the rotating motor to make the entire transport box turn, so that The side baffle faces the lime water strengthening box. At this time, the transport box is pushed to a baffle whose height of its sloping bottom plate is higher than that of the lime water strengthening box by the second electric push rod. The second stepper motor is controlled to drive the gear thereon to rotate on the second rack track, so that the side baffle is opened, and the broken concrete falls from the sloping bottom plate into the lime water strengthening box through the side discharge port. After completion, the second electric push rod and the third electric push rod are retracted. This is a material pouring method. Another method is not to rotate the direction of the transport box by the rotating motor, but to control the height difference of the two second electric push rods, cooperate with the upper connecting rod, bearing, and bearing track, so that the broken concrete falls into the lime water strengthening box from the sloping opening on the top of the transport box at an angle; after the pouring is completed, the broken concrete slides to the strengthened discharge channel. At this time, lime water is introduced through the lime water inlet for soaking. After soaking for a certain period of time, excess lime water is extracted through the lime water outlet. At this time, the third electric push rod is raised again to move the transport box to the bottom of the lime water strengthening box, so that the top opening of the transport box is located below the lime water strengthening outlet electric valve, and the valve is opened, and the strengthened concrete thereon falls into the box body. After completion, the transport box is moved to the side of the carbon dioxide strengthening unit, and the gear thereon is driven by the third stepper motor to rotate on the third rack track, so that the sealing baffle is opened, and the strengthened concrete in the transport box is poured into the carbon dioxide strengthening box in the same way as adding the lime water strengthening unit. After completion, the sealing baffle is closed, and then the vacuum pump is started to vacuum the box body through the carbon dioxide outlet. Vacuuming is performed, and after a period of time, vacuuming is stopped and carbon dioxide is introduced through the carbon dioxide feed port, and the concentration of carbon dioxide inside the box is monitored in real time through the carbon dioxide sensor. When the concentration of carbon dioxide no longer changes, or the concentration change is only related to the amount of carbon dioxide introduced, it can be judged that the strengthening is completed. At this time, the introduction of carbon dioxide is stopped and the excess carbon dioxide is extracted through the vacuum pump. After completion, the sealing baffle is opened, and the carbon dioxide strengthening box is raised through the third electric push rod, and the transport box is moved to the bottom of the carbon dioxide strengthening discharge electric valve, and the valve is opened, and the strengthened concrete falls into the transport box; then the transfer unit is moved to the bottom of the air-drying unit, and the blower is turned on to air-dry the strengthened concrete inside the transport box, and it can be moved to the second track after completion;

[0020] S3. Transfer and storage of recycled concrete: After the concrete is strengthened in the processing and strengthening tank, the transfer unit can be moved to the second transport track through the first transport track, and finally moved to the middle of the back baffle of the storage tank body. The strengthened concrete aggregate is poured into the storage tank body by opening the side baffle. The falling concrete aggregate is cushioned by the rubber cushion pad to reduce the performance loss caused by falling. At this point, the entire waste concrete strengthening and recycling storage is completed, and it can be directly taken out through the opening of the storage tank body when needed.

[0021] From the above, the beneficial effects of the construction waste pool capable of absorbing carbon dioxide and the use method thereof of the present invention are as follows:

[0022] 1. Compared with the prior art, the garbage pool is only used as a garbage storage point. The main garbage pool part of the present invention can use the garbage pool body as a storage point for various construction wastes by closing the first floor, and can also be used as a garbage pool for storing renewable concrete waste by opening the first floor and closing the second floor. After storing the garbage, the pneumatic hammer can be lowered by the preliminary crushing unit and the full-coverage concrete can be initially crushed back and forth on the special crushing track. The smaller concrete falls into the funnel discharge plate through the screen opening of the second floor in advance for crushing, and the larger concrete falls directly for crushing by opening the second floor. This method greatly improves the crushing efficiency. After the crushing is completed, the baffle can be closed repeatedly to store garbage again, which can also greatly improve the garbage recycling efficiency and save garbage storage space.

[0023] 2. The present invention arranges a hopper discharge plate at the bottom of the garbage pool, and cooperates with the jaw crusher at the bottom of the discharge port, so that the waste concrete can enter the jaw crusher in an orderly manner for secondary crushing after the initial crushing. After the crushing is completed, it can be transported by the transfer unit installed on the first transport track. The first transport track effectively connects various processing units such as the transfer unit, the lime water strengthening unit, the carbon dioxide strengthening unit, and the air drying unit, so that the transfer unit can be quickly switched between various processing areas. The special-shaped structure design on the transfer unit allows the transport box to be loaded and unloaded from the top, and can also be unloaded from the side through the bottom sloped bottom plate. In conjunction with the lime water strengthening box, the carbon dioxide strengthening unit, the air drying unit, the transfer unit can be quickly switched between various processing areas. The various structures on the carbon dioxide strengthening box make the strengthening and transportation of concrete waste more efficient and convenient. The different internal structural designs of the lime water strengthening box and the carbon dioxide strengthening box allow the lime water strengthening box to be immersed and strengthened in an open environment, while the carbon dioxide strengthening box is controlled by vacuum strengthening in a closed environment. Based on the characteristics of large pores, many edges and corners and low strength of recycled aggregate particles, the aggregate pore microenvironment is vacuumed and ultra-fine lime slurry is pumped in to achieve the strengthening of recycled concrete aggregate particles, which greatly improves the strengthening performance of prepared concrete and improves the strengthening efficiency. At the same time, the entire processing area is located underground, so the noise of preparing strengthened recycled concrete will be greatly reduced, and the pollution to the external environment and aesthetics will also be reduced.

[0024] 3. The present invention connects the processing and strengthening pool part under the ground with the storage pool part on the ground through the transfer track part, so that the transfer unit thereon can transfer concrete between the parts through the track, realize the output and storage of the strengthened concrete, save space and improve the transfer efficiency. At the same time, because the concrete can be continuously output to the storage pool part for storage, the waste concrete can also be continuously added to the main garbage pool part for unloading, which greatly increases the storable amount of waste concrete construction waste, which is equivalent to a recycled strengthened concrete production line, and effectively improves the utilization rate of construction waste concrete.

At the same time, the bottom of the pneumatic hammer 1104 is controlled to The electric trolley moves back and forth on the crushing track 1103 to achieve all-round coverage and crushing inside the box. The crushing can be stopped after the concrete waste is crushed to a suitable size. Here, the suitable size refers to the concrete size being smaller than the discharge port 2001a, and then it can enter the secondary crushing unit 2100. After the crushing is completed, the first stepper motor 1204 can control the gear thereon to rotate on the first rack track 1203, so that the second bottom plate 1202 is also moved out of the second slot 1001d, so that the construction concrete garbage after the preliminary crushing on the second bottom plate 1202 falls into the middle opening of the garbage pool bottom plate 1001b, and then falls into the funnel discharge plate 2001 for the next step.

[0062] Compared with the prior art, the garbage pool is only used as a garbage storage point. The main garbage pool part 1000 of the present invention can use the garbage pool body 1001 as a storage point for various construction wastes by closing the first floor plate 1201, and can also use the garbage pool as a garbage pool specifically for storing renewable concrete waste by opening the first floor plate 1201 and closing the second floor plate 1202. After storing the garbage, the pneumatic hammer 1104 can be lowered by the preliminary crushing unit 1100 and the concrete can be initially crushed back and forth on the special crushing track 1103. The smaller concrete will fall into the funnel discharge plate 2001 through the screen opening 1202a of the second floor plate 1202 in advance, and the larger concrete will fall directly to be crushed by opening the second floor plate 1202. This method greatly improves the crushing efficiency. After the crushing is completed, the baffle can be closed repeatedly to store the garbage again, which can also greatly improve the garbage recycling efficiency and save garbage storage space.

[0065] Among them, the secondary crushing unit 2100 is mainly composed of a jaw crusher, and the lime water strengthening unit 2300 is mainly composed of a lime water strengthening box 2301, the top of which is set as an opening, and the bottom is set as a sloped bottom plate extending to the middle, and the middle is a strengthened discharge channel 2303, which can be connected to the lime water strengthened discharge electric valve 2306 below. The strengthened discharge channel 2303 is in a closed state when not discharging, that is, materials can be accumulated and stored on it, which is also the lowest point of the sloped bottom plate.

[0066] The carbon dioxide enhancement unit 2400 is mainly composed of a carbon dioxide enhancement box 2401. The main structure of the carbon dioxide enhancement box 2401 is the same as that of the lime water enhancement box 2301, and also includes a third electric push rod 2304, a perforated sloped channel 2302, and an enhanced discharge channel 2303. At the same time, a carbon dioxide enhancement discharge electric valve 2405 is provided in the middle of the bottom surface of the carbon dioxide enhancement box 2401, which is connected to the enhanced discharge channel of the carbon dioxide enhancement box 2401. The carbon dioxide enhancement discharge electric valve 2405 is provided with a carbon dioxide feed port 2404a and a carbon dioxide discharge port 2404b on both sides, and both are connected to the perforated sloped channels on both sides. Baffle rails 2401a are provided on both sides of the top of the carbon dioxide enhancement box 2401, and a sealing baffle 2403 is installed on the baffle rail 2401a. A third rack rail 2403a is provided on one side of the sealing baffle 2403, and a third stepper motor 2402 is provided at a corresponding position on the periphery of the box body. The third stepper motor 2402 can engage with the third rack rail 2403a through the gear thereon to control the opening and closing of the sealing baffle 2403; the carbon dioxide enhancement box 2401 is also provided with a carbon dioxide sensor 2406, which can be used to monitor the concentration change of carbon dioxide inside the box body after the box body is closed. When the concentration no longer changes, it means that the internal enhancement is completed.

[0067] In the present invention, the lime water feed port 2305a can be connected to the lime water pump inlet pipe, and lime water is added to the interior of the box for soaking through an external mechanism, while the lime water discharge port 2305b is connected to the lime water pump outlet pipe to extract excess lime water from the box; the carbon dioxide feed port 2404a can be connected to a high-concentration carbon dioxide pump such as that in a cement plant, thermal power plant, or steel plant, and then filled with carbon dioxide, while the carbon dioxide discharge port 2404b is connected to a vacuum pump. First, the air in the box can be extracted before carbon dioxide strengthening, so that the strengthened concrete can have higher performance. Second, excess carbon dioxide can be extracted after strengthening is completed to prevent direct overflow and pollution of the environment.

[0068] The purpose of setting this structure is that after the primary crushing of the main garbage pool part 1000 is completed, the concrete waste falls into the funnel discharge plate 2001, then slides into the discharge port 2001a, and then enters the jaw crusher of the secondary crushing unit 2100 through the discharge port 2001a for crushing. At this time, the transfer unit 2200 is controlled to move on the first transport track 2005 to the bottom of the discharge port of the jaw crusher, and the crushed aggregate falls into the interior of the box from the top of the transport box 2206 to the left through the discharge track of the jaw crusher. After a sufficient amount of crushed concrete is stored, the discharge is stopped, and the transfer unit 2200 is moved at the same time. The first transport track 2005 is moved to the lime water strengthening unit 2300. At this time, the third electric push rod 2304 on it lowers the lime water strengthening box 2301 to a suitable height. The second electric push rod mounting plate 2201 is rotated by the rotary motor to turn the entire transport box 2206 so that the side baffle 2207 faces the lime water strengthening box 2301. At this time, the second electric push rod 2202 pushes the transport box 2206 to a height of its sloped bottom plate 2206b higher than the baffle of the lime water strengthening box 2301. The second stepping motor 2209 is controlled to drive the gear on it to move. The wheel rotates on the second rack track 2208, so that the side baffle 2207 is opened, and the crushed concrete falls from the sloped bottom plate 2206b through the side discharge port 2206a into the lime water strengthening box 2301. After completion, the second electric push rod 2202 and the third electric push rod 2304 are retracted. This is a material pouring method. Another method is not to rotate the direction of the transport box 2206 by the rotating motor, but to control the height difference of the two second electric push rods 2202, cooperate with the upper connecting rod 2203, bearing 2204, and bearing track 2205, so that the crushed concrete is discharged from the top of the transport box 2206. The crushed concrete falls into the lime water strengthening box 2301 through the sloped opening; after the pouring is completed, the crushed concrete slides to the top of the strengthening discharge channel 2303, and at this time, lime water is introduced through the lime water feed port 2305a for soaking. After soaking for a certain period of time, excess lime water is extracted through the lime water discharge port 2305b. At this time, the third electric push rod 2304 is raised again to move the transport box 2206 to the bottom of the lime water strengthening box 2301, so that the top opening of the transport box 2206 is located below the lime water strengthening discharge electric valve 2306, and the valve is opened, and the strengthened concrete thereon falls into the box.

[0069] After completion, the transport box 2206 is moved to the side of the carbon dioxide strengthening unit 2400, and the gear thereon is driven by the third stepper motor 2402 to rotate on the third rack track 2403a, so that the sealing baffle 2403 is opened, and the reinforced concrete in the transport box 2206 is poured into the carbon dioxide strengthening box 2401 in the same way as adding the lime water strengthening unit 2300. After completion, the sealing baffle 2403 is closed, and then the vacuum pump is started to evacuate the box through the carbon dioxide outlet 2404b. After a period of time, the vacuum is stopped and carbon dioxide is introduced through the carbon dioxide inlet 2404a, and the concentration of carbon dioxide in the box is monitored in real time by the carbon dioxide sensor 2406. When the concentration of carbon dioxide no longer changes, or the concentration change is only related to the amount of carbon dioxide introduced, it can be judged that the strengthening is completed. At this time, the introduction of carbon dioxide is stopped and the excess carbon dioxide is extracted through a vacuum pump. After completion, the sealing baffle 2403 is opened, and the carbon dioxide strengthening box 2401 is raised by the third electric push rod 2304, and the transport box 2206 is moved to the bottom of the carbon dioxide strengthening discharge electric valve 2405, and the valve is opened. The strengthened concrete falls into the transport box 2206; then the transfer unit 2200 is moved to the bottom of the air-drying unit 2500, and the blower 2502 is turned on to air-dry the strengthened concrete inside the transport box 2206. After completion, it can be moved to the second track 3002.

[0070] Compared with the prior art, the present invention, by setting a funnel discharge plate 2001 at the bottom of the garbage pool, cooperates with the jaw crusher at the bottom of its discharge port 2001a, so that the waste concrete can enter the jaw crusher in an orderly manner for secondary crushing after the initial crushing, and after crushing, it can be transported by the transfer unit 2200 installed on the first transport track 2005. The first transport track 2005 effectively connects various processing units such as the transfer unit 2200, the lime water strengthening unit 2300, the carbon dioxide strengthening unit 2400, and the air drying unit 2500, so that the transfer unit 2200 can be quickly switched between various processing areas, and the special-shaped structural design on the transfer unit 2200 allows the transport box 2206 to be loaded and unloaded from the top, and can also be loaded and unloaded through the sloped bottom plate 2206 at the bottom. b. Unloading from the side, in conjunction with the various structures on the lime water strengthening box 2301 and the carbon dioxide strengthening box 2401, the strengthening and transportation of concrete waste is more efficient and convenient. The different internal structural designs of the lime water strengthening box 2301 and the carbon dioxide strengthening box 2401 allow the lime water strengthening box 2301 to be immersed and strengthened in an open environment, while the carbon dioxide strengthening box 2401 is controlled to be vacuum strengthened in a closed environment. Based on the characteristics of large pores, many edges and corners, and low strength of the regenerated aggregate particles, the aggregate pore microenvironment is vacuumed and ultra-fine lime slurry is pumped in to achieve the strengthening of the recycled concrete aggregate particles, which greatly improves the strengthening performance of the prepared concrete and improves the strengthening efficiency. At the same time, the entire processing area is located underground, so the noise of preparing strengthened recycled concrete will be greatly reduced, and the pollution to the external environment and aesthetics will also be reduced.

[0071] Depend on Fig.12 As shown, the transfer track part 3000 is mainly composed of a lifting track mounting plate 3001, one end of which is installed below the air-drying unit mounting plate 2003a under the ground 0000, and the other end is installed in the middle of the back baffle of the storage tank body 4001 on the ground 0000, and a second pillar 3003 is provided at the bottom of the part located on the ground 0000 for support; a second transport track 3002 is provided on the lifting track mounting plate 3001, and the bottom end of the second transport track 3002 is spliced ​​with the first transport track 2005, and the other end thereof extends to the back baffle of the storage tank body 4001. The purpose of setting up this structure is that after the concrete is strengthened in the processing strengthening pool part 2000, the transfer unit 2200 can be moved to the second transport track 3002 through the first transport track 2005, and finally moved to the middle of the back baffle of the storage pool body 4001, and the strengthened concrete aggregate is poured into the storage pool body 4001 by opening the side baffle 2207, and the fallen concrete aggregate is cushioned by the rubber buffer pad 4002 to reduce the performance loss caused by falling. At this point, the entire waste concrete strengthening and recycling storage is completed, and it can be taken out through the opening of the storage pool body 4001 when needed.

[0072] Compared with the prior art, the present invention connects the processing and strengthening pool part 2000 under the ground 0000 with the storage pool part 4000 on the ground 0000 through the transfer track part 3000, so that the transfer unit 2200 thereon can transfer concrete between the parts through the track, realize the output and storage of the strengthened concrete, save space and improve the transfer efficiency. At the same time, because the concrete can be continuously output to the storage pool part 4000 for storage, the waste concrete can also be continuously added to the main garbage pool part 1000 for unloading, which greatly increases the storable amount of waste concrete construction waste, which is equivalent to a recycled strengthened concrete production line, and effectively improves the utilization rate of construction waste concrete.

[0073] Depend on Fig.13 As shown, the storage tank part 4000 is mainly composed of a storage tank body 4001, and the storage tank body 4001 has a similar structure to the garbage tank body 1001, but the garbage tank floor 1001b at the bottom is a fully enclosed structure, and a number of rubber buffer pads 4002 are provided on the garbage tank floor at the bottom of the storage tank body 4001 to catch the fallen recycled reinforced concrete.

[0075] S1. Storage and preliminary crushing and unloading: When the garbage pool is used as an ordinary garbage pool to store various construction wastes, the first stepper motor 1204 controls the gear thereon to rotate on the first rack track 1203, thereby moving the first floor plate 1201 to the innermost side of the first slot 1001c, thereby realizing the closure of the bottom of the garbage pool body 1001, thereby realizing the internal closure of the entire garbage pool, and it can be used as an ordinary garbage pool; when the garbage pool is used as a garbage pool for recycling and strengthening waste concrete and building masonry, the first stepper motor 1204 controls the gear thereon to rotate on the first rack track 1203, thereby moving the first floor plate 1201 out of the inner side of the first slot 1001c, and at the same time moving the second floor plate 1202 to the innermost side of the second slot 1001d, so that the bottom of the garbage pool body 1001 is the second floor plate 1202 with the screen opening 1202a as a closed floor, and at this time, it can be accessed from the entrance 100 1a pours construction waste into the garbage pool. After completion, the crushing track lifting plate 1102 is lowered to a suitable height by the first electric push rod 1101, and the pneumatic hammer 1104 is started for preliminary crushing. At the same time, the electric trolley at the bottom of the pneumatic hammer 1104 is controlled to move back and forth on the crushing track 1103 to achieve all-round coverage and crushing inside the box. The crushing can be stopped after the concrete waste is crushed to a suitable size. Here, the suitable size refers to the size of the concrete being smaller than the discharge port 2001a, and then it can enter the secondary crushing unit 2100. After the crushing is completed, the gear on it can be controlled by the first stepper motor 1204 to rotate on the first rack track 1203, so that the second-layer bottom plate 1202 is also moved out of the second-layer slot 1001d, so that the construction concrete garbage that has been initially crushed on the second-layer bottom plate 1202 falls into the middle opening of the garbage pool bottom plate 1001b, and then falls into the funnel discharge plate 2001 for the next step;

[0076] S2, secondary crushing and strengthening: after the primary crushing of the main garbage pool part 1000 is completed, the concrete waste falls into the funnel discharge plate 2001, then slides into the discharge port 2001a, and then enters the jaw crusher of the secondary crushing unit 2100 through the discharge port 2001a for crushing. At this time, the transfer unit 2200 is controlled to move on the first transport track 2005 to the bottom of the discharge port of the jaw crusher, and the crushed aggregate falls into the box body from the sloped opening on the top of the transport box 2206 to the left through the discharge track of the jaw crusher. After a sufficient amount of crushed concrete is stored, the discharge is stopped, and the transfer unit 2200 is moved to the first transport track 2005 at the lime water strengthening unit 2300. At this time, the lime water strengthening box 2301 is lowered to a suitable height by the third electric push rod 2304 thereon, and the second electric push rod mounting plate 2201 is rotated by the rotating motor to make the entire transport box 2206 turn, so that the side baffle 2207 faces the lime water strengthening box 2301. At this time, the second electric push rod 2202 pushes the transport box 2206 to a height of its sloped bottom plate 2206b higher than the baffle of the lime water strengthening box 2301, and controls the second stepping motor 2209 to drive the gear thereon to rotate on the second rack track 2208, so that the side baffle 2207 is opened, and the broken concrete falls from the sloped bottom plate 2206b through the side discharge port 2206a into the lime water strengthening box 2301. After completion, the second electric push rod 2202 and the third electric push rod 2304 are retracted. This is a material pouring method. Another method is not to rotate the direction of the transport box 2206 by the rotating motor, but to control the height difference between the two second electric push rods 2202, cooperate with the upper connecting rod 2203, the bearing 2204, and the bearing track 2205, so that the broken concrete falls obliquely from the sloped opening at the top of the transport box 2206 into the lime water strengthening box 2301;After pouring, the crushed concrete slides to the top of the strengthening discharge channel 2303, and then lime water is introduced through the lime water feeding port 2305a for soaking. After soaking for a certain period of time, the excess lime water is extracted through the lime water discharge port 2305b. At this time, the third electric push rod 2304 is raised again to move the transport box 2206 to the bottom of the lime water strengthening box 2301, so that the top opening of the transport box 2206 is located below the lime water strengthening discharge electric valve 2306, and the valve is opened, and the strengthened concrete thereon falls into the box body. After completion, the transport box 2206 is moved to the side of the carbon dioxide strengthening unit 2400, and the gear thereon is driven by the third stepping motor 2402 to rotate on the third rack track 2403a, so that the sealing baffle 2403 is opened, and the strengthened concrete in the transport box 2206 is poured into the carbon dioxide strengthening box 2401 in the same way as adding the lime water strengthening unit 2300. After completion, the sealing baffle 2403 is closed, and then the start The vacuum pump evacuates the box through the carbon dioxide outlet 2404b, stops evacuating after a period of time, and introduces carbon dioxide through the carbon dioxide inlet 2404a, and monitors the concentration of carbon dioxide inside the box in real time through the carbon dioxide sensor 2406. When the concentration of carbon dioxide no longer changes, or the concentration change is only related to the amount of carbon dioxide introduced, it can be judged that the strengthening is completed. At this time, the introduction of carbon dioxide is stopped and the excess carbon dioxide is extracted through the vacuum pump. After completion, the sealing baffle 2403 is opened, and the carbon dioxide strengthening box 2401 is raised by the third electric push rod 2304, and the transport box 2206 is moved to the bottom of the carbon dioxide strengthening discharge electric valve 2405, and the valve is opened, and the strengthened concrete falls into the transport box 2206; then the transfer unit 2200 is moved to the bottom of the air-drying unit 2500, and the blower 2502 is turned on to air-dry the strengthened concrete inside the transport box 2206, and after completion, it can be moved to the second track 3002;

Storage and preliminary crushing and unloading: When the garbage pool is used as an ordinary garbage pool to store various types of construction waste, the first stepper motor (1204) controls the gear on it to rotate on the first rack track (1203), thereby causing the first floor plate (1201) to move to the innermost side of the first slot (1001c), thereby achieving closure of the bottom of the garbage pool body (1001), thereby achieving internal closure of the entire garbage pool, and the garbage pool can be used as an ordinary garbage pool; when the garbage pool is used as a garbage pool for recycling and strengthening waste concrete and building masonry, the first stepper motor (1204) controls the gear on it to rotate on the first rack track (1203), thereby causing the first floor plate (1201) to move out of the inner side of the first slot (1001c), and at the same time causing the second floor plate (1202) to move to the innermost side of the second slot (1001d), so that the bottom of the garbage pool body (1001) is closed by the second floor plate (1202a) with the screen opening (1202a). 1202) is used as a closed bottom plate. At this time, construction waste can be poured into the garbage pool from the entrance (1001a). After completion, the crushing track lifting plate (1102) is lowered to a suitable height by the first electric push rod (1101), and the pneumatic hammer (1104) is started for preliminary crushing. At the same time, the electric trolley at the bottom of the pneumatic hammer (1104) is controlled to move back and forth on the crushing track (1103) to achieve all-round coverage crushing inside the box. After the concrete waste is crushed to a suitable size, the crushing can be stopped. After the crushing is completed, the gear on it can be controlled by the first stepper motor (1204) to rotate on the first rack track (1203), thereby moving the second bottom plate (1202) out of the second slot (1001d), so that the construction concrete waste on the second bottom plate (1202) that has been initially crushed falls into the middle opening of the garbage pool bottom plate (1001b), and then falls into the funnel unloading plate (2001) for the next step; S2. Secondary crushing and strengthening: After the primary crushing of the main garbage pool (1000) is completed, the concrete waste falls into the hopper discharge plate (2001), then slides into the discharge port (2001a), and then enters the jaw crusher of the secondary crushing unit (2100) through the discharge port (2001a) for crushing. At this time, the transfer unit (2200) is controlled to move on the first transport track (2005) to the bottom of the discharge port of the jaw crusher. The crushed aggregate is discharged from the transport track of the jaw crusher. The top of the transport box (2206) opens to the left and the sloped opening falls into the box body. After a sufficient amount of crushed concrete is stored, the material is stopped. At the same time, the transfer unit (2200) is moved to the first transport track (2005) at the lime water strengthening unit (2300). At this time, the lime water strengthening box (2301) is lowered to a suitable height through the third electric push rod (2304) on it, and the second electric push rod mounting plate (2201) is rotated by the rotating motor, so that the entire transport box (2206) is turned, allowing the side baffle (2207) to rotate. Facing the limewater strengthening box (2301), the transport box (2206) is pushed by the second electric push rod (2202) to a height of its sloped bottom plate (2206b) higher than the baffle of the limewater strengthening box (2301), and the second stepping motor (2209) is controlled to drive the gear thereon to rotate on the second rack track (2208), so that the side baffle (2207) is opened, and the crushed concrete falls from the sloped bottom plate (2206b) through the side discharge port (2206a) into the limewater strengthening box (2301). ), after completion, the second electric push rod (2202) and the third electric push rod (2304) are retracted. This is a method of discharging materials. Another method is to not rotate the direction of the transport box (2206) by the rotating motor, but to control the height difference between the two second electric push rods (2202) and cooperate with the upper connecting rod (2203), the bearing (2204), and the bearing track (2205) to make the crushed concrete fall obliquely from the sloped opening at the top of the transport box (2206) into the lime water strengthening box (2301);After pouring, the crushed concrete slides to the top of the reinforced discharge channel (2303), and then lime water is introduced through the lime water feed port (2305a) for soaking. After soaking for a certain period of time, excess lime water is pumped out through the lime water discharge port (2305b). At this time, the third electric push rod (2304) is raised again to move the transport box (2206) to the bottom of the lime water reinforced box (2301), so that the top opening of the transport box (2206) is located below the lime water reinforced discharge electric valve (2306), and the electric push rod (2304) is opened. The valve is used to allow the reinforced concrete on the valve to fall into the box body. After completion, the transport box (2206) is moved to the side of the carbon dioxide reinforcement unit (2400). The gear on the transport box (2206) is driven by the third stepper motor (2402) to rotate on the third rack track (2403a), so that the sealing baffle (2403) is opened. The reinforced concrete in the transport box (2206) is poured into the carbon dioxide reinforcement box (2401) in the same way as the lime water reinforcement unit (2300). After completion, the sealing baffle (2403) is closed, and then the vacuum pump is started to evacuate the box body through the carbon dioxide discharge port (2404b). After a period of time, the vacuum is stopped and carbon dioxide is introduced through the carbon dioxide feed port (2404a). The concentration of carbon dioxide in the box body is monitored in real time through the carbon dioxide sensor (2406). When the concentration of carbon dioxide no longer changes, or the concentration change is only related to the amount of carbon dioxide introduced, it can be judged that the reinforcement is completed. At this time, the introduction of carbon dioxide is stopped and the excess carbon dioxide is extracted through the vacuum pump. After completion, the sealing baffle (2403) is opened. 403), the carbon dioxide strengthening box (2401) is raised by the third electric push rod (2304), the transport box (2206) is moved to the bottom of the carbon dioxide strengthening discharge electric valve (2405), the valve is opened, and the strengthened concrete falls into the transport box (2206); then the transfer unit (2200) is moved to the bottom of the air drying unit (2500), the blower (2502) is turned on to air dry the strengthened concrete inside the transport box (2206), and after completion, it can be moved to the second transport track (3002); S3. Transfer and storage of recycled concrete: After the concrete is strengthened in the processing strengthening tank part (2000), the transfer unit (2200) can be moved to the second transport track (3002) through the first transport track (2005), and finally moved to the middle of the back baffle of the storage tank body (4001). The strengthened concrete aggregate is poured into the storage tank body (4001) by opening the side baffle (2207). The rubber buffer pad (4002) cushions the falling concrete aggregate to reduce the performance loss caused by falling. At this point, the entire waste concrete strengthening and recycling storage is completed, and when needed, it can be directly taken out through the opening of the storage tank body (4001).
