With the acceleration of the industrialization and urbanization processes, the construction industry has also developed rapidly, and the construction waste generated during the building construction process is increasing day by day. A large amount of construction waste is randomly piled up, which not only occupies land but also pollutes the environment. Under the action of temperature, moisture, etc., some organic substances decompose, generating harmful gases, directly or indirectly affecting the air quality, and it is necessary to reasonably discharge the construction waste.

The output end of the liquid pumping pump 402 is connected with a liquid outlet pipe 406 through a flange. One end of the liquid outlet pipe 406 fixedly penetrates into the interior of the extraction tank 301. By starting the liquid pumping pump 402, the water reducing agent in the reagent barrel 401 is pumped into the liquid outlet pipe 406 through the liquid pumping pipe 403, and then the water reducing agent is transported into the extraction tank 301, which is convenient for accelerating the mixing of water and concrete through the water reducing agent and accelerating the formation speed of the concrete slurry.

[0034] According to Figures 1-2 and Figures 5-6 As shown in the figure, mounting holes 407 are respectively arranged on the outer surfaces of both sides of the reagent barrel 401. Transparent observation windows 404 are fixedly installed in the two mounting holes 407. Scale lines 405 are arranged on the outer surfaces of both sides of the reagent barrel 401 near the transparent observation windows 404. A liquid injection pipe 408 is fixedly communicated with the top of the reagent barrel 401. The blowing component 5 includes a cover plate 501. A blower 503 is fixedly installed on the top of the cover plate 501. The output end of the blower 503 is fixedly connected with an air supply pipe 504. One end of the air supply pipe 504 fixedly penetrates into the interior of the cover plate 501. Through the transparent observation window 404 and the scale line 405, it is convenient for the staff to observe the change of the water reducing agent delivery volume. When an appropriate amount of water reducing agent is delivered, the liquid pumping pump 402 is timely closed to prevent the excessive or insufficient delivery of the water reducing agent and affect the subsequent effect. The blower 503 is started to pump the external air into the air supply pipe 504, and then the air is blown into the filter barrel 302 through the air outlet hood 505, which can accelerate the evaporation of the water in the solid particles inside the filter barrel 302.

[0035] According to Figures 1-2 、 Figure 5 and Figure 7 As shown, one end of the air supply pipe 504 is fixedly connected with an air outlet hood 505. A reinforcing plate 304 is fixedly installed on the outer surface of the extraction tank 301 near the top. A forward and reverse motor 502 is fixedly installed on the top of the reinforcing plate 304. The output end of the forward and reverse motor 502 is fixedly installed at the bottom of the cover plate 501 near the front surface. Two sliding holes 307 are formed in the top of the reinforcing plate 304. By starting the forward and reverse motor 502, the cover plate 501 is driven to rotate to the top of the extraction tank 301 to cover the top of the extraction tank 301, preventing the cement slurry from accidentally splashing out during the subsequent centrifugation process.

[0036] According to Figure 2 and Figure 5 As shown, clamping posts 507 are movably embedded in the two sliding holes 307. Reinforcing rods 506 are fixedly installed at the tops of the two clamping posts 507. The tops of the two reinforcing rods 506 are fixedly installed at the bottom of the cover plate 501. A traction rod 508 is fixedly installed on the front surface of the cover plate 501. One end of the traction rod 508 is fixedly installed on the outer surface of one of the clamping posts 507 near the bottom. By the rotation of the cover plate 501, the two reinforcing rods 506 and the clamping posts 507 are driven to slide in the two sliding holes 307 at the same time. The two clamping posts 507 are clamped in the sliding holes 307 to limit the reinforcing rods 506, thereby limiting the cover plate 501 and increasing the stability. Under the pulling of the traction rod 508, the balance of the cover plate 501 is increased to prevent the cover plate 501 from tilting and being unstable.

[0037] According to Figure 1 and Figures 3-4 As shown, the feeding assembly 2 includes a feeding box 201. A second motor 202 is fixedly installed on the top of the feeding box 201 through an auxiliary rod. The output end of the second motor 202 is fixedly installed with a rotating shaft 206. A spiral blade 207 is fixedly installed on the outer surface of the rotating shaft 206. A feeding pipe 203 is fixedly communicated with the outer surface of the feeding box 201 near the bottom. A blanking pipe 204 is fixedly communicated with the outer surface of the feeding box 201 near the top. A telescopic pipe 205 is movably sleeved on the outer surface of the blanking pipe 204. By starting the second motor 202, the rotating shaft 206 is driven to rotate, and then the spiral blade 207 is driven to rotate to convey the concrete particles inside the feeding box 201 upward, and then enter the telescopic pipe 205 through the blanking pipe 204. The bottom end of the telescopic pipe 205 faces the inside of the filter barrel 302, so that the concrete particles fall into the filter barrel 302.

[0038] According to Figures 3-4As shown, limit blocks 209 are fixedly installed on both the front and rear surfaces of the telescopic pipe 205 near one side. Sliding grooves 208 are provided on both the front and rear surfaces of the blanking pipe 204. The outer surfaces of the two limit blocks 209 are respectively movably embedded in the two sliding grooves 208. One end of the rotating shaft 206 is movably embedded in the bottom surface inside the feeding box 201. The outer surface of the spiral blade 207 is in contact with the inner wall of the feeding box 201. The telescopic pipe 205 can be limited by the limit blocks 209 and the sliding grooves 208, which is convenient for the subsequent manual tightening of bolts into the corresponding threaded grooves to assist in fixing the telescopic pipe 205 and increasing the stability between the telescopic pipe 205 and the blanking pipe 204.

[0039] According to Figures 1-2 and Figure 6 As shown, a support frame 303 is fixedly installed on the outer surface of the extraction tank 301. A fixing plate 7 is fixedly installed on the outer surface of the support frame 303. A PLC controller 9 is installed on the front surface of the fixing plate 7 near the top through screws, and a frequency converter 8 is installed on the front surface of the fixing plate 7 near the bottom through screws. The bottom surface inside the extraction tank 301 is arranged in an arc shape. The support frame 303 facilitates the support and installation of the extraction tank 301. The fixing plate 7 facilitates the installation of the PLC controller 9 and the frequency converter 8. The PLC controller 9 can control the opening and closing of other devices. The frequency converter 8 facilitates the adjustment of the rotation speed of the first motor 308.

[0040] According to Figures 7-9 As shown, a rotating hole 319 is provided at the center of the bottom surface inside the extraction tank 301. A sealing sleeve 320 is fixedly connected to the inner wall of the rotating hole 319. The outer surface of the rotating rod 312 near the top is in contact with the inner wall of the sealing sleeve 320. A plurality of L-shaped grooves 315 are provided at the bottom of the filter barrel 302. Limiting grooves 316 are provided on the inner walls of the plurality of L-shaped grooves 315. The outer surfaces of the plurality of L-shaped rods 314 near one end are respectively movably embedded in the plurality of limiting grooves 316. The outer surfaces of the plurality of L-shaped rods 314 near the other end are respectively movably embedded in the plurality of L-shaped grooves 315. The rotating hole 319 facilitates the rotation of the rotating rod 312. Under the sealing of the sealing sleeve 320, the sealing performance between the rotating hole 319 and the rotating rod 312 can be increased to prevent water leakage. The L-shaped rod 314 is inserted into the L-shaped groove 315, and then the filter barrel 302 is rotated so that one end of the L-shaped rod 314 slides into the limiting groove 316, which is convenient for limiting the filter barrel 302 and driving the filter barrel 302 to rotate at the same time.

[0041] According to Figure 2 、 Figures 6-7 and Figure 9As shown, the bottom of the filter barrel 302 is in contact with the top of the turntable 313. An annular support plate 309 is fixedly installed on the outer surface of the filter barrel 302 near the top. A plurality of ball grooves 317 are formed in the bottom of the annular support plate 309. A rolling ball 318 is movably embedded in each of the plurality of ball grooves 317. A backing plate 310 is fixedly installed on the inner wall of the extraction tank 301 near the top. The outer surface of the filter barrel 302 is movably embedded in the backing plate 310. The outer surfaces of the plurality of rolling balls 318 are in contact with the top of the backing plate 310. One end of the connecting pipe 306 fixedly penetrates into the storage liquid tank 6. The backing plate 310 facilitates the auxiliary support of the filter barrel 302 and increases its stability. When the filter barrel 302 rotates, it drives the annular support plate 309 to rotate together. The rolling of the plurality of rolling balls 318 reduces the friction force and facilitates the smoother rotation of the filter barrel 302.

[0042] The effect achieved by the entire mechanism is that when in use, the crusher 1 is composed of a feeding device, a crushing chamber, a discharging device, a transmission device and a control system. The discharging pipe of the crusher 1 is located above the feeding pipeline 203, as Figure 1As shown, the selected building concrete blocks are poured into the crushing chamber of the crusher 1 through the feed inlet of the crusher 1. The crushing device is started through the control system of the crusher 1. The concrete is impacted, sheared and rubbed by the high-speed rotating crushing tools (such as hammers, tooth plates, etc.), so that the concrete blocks are broken into smaller particles. Then, the crushed concrete particles are discharged into the feed pipeline 203 through the discharge pipe, and the crushed concrete particles are discharged into the feeding box 201 through the feed pipeline 203. The second motor 202, the first motor 308, the solenoid valve 321, the liquid extraction pump 402, the forward and reverse motor 502, the fan 503, the frequency converter 8 and the PLC controller 9 are electrically connected. The front and rear surfaces of the telescopic pipeline 205 are both assisted and fixed by hand-tightening bolts, increasing the stability between the telescopic pipeline 205 and the blanking pipeline 204. The second motor 202 is started through the PLC controller 9. The output end of the second motor 202 drives the rotating shaft 206 to rotate, and then drives the spiral blade 207 to rotate, conveying the concrete particles inside the feeding box 201 upward. Then, the concrete particles enter the telescopic pipeline 205 through the blanking pipeline 204. The bottom end of the telescopic pipeline 205 faces the inside of the filter barrel 302, so that the concrete particles fall into the filter barrel 302. Then, an external faucet is connected through a water pipe to convey an appropriate amount of water into the filter barrel 302 and the extraction pool 301. When the concrete particles are conveyed, loosen the two hand-tightening bolts, and then slide the telescopic pipeline 205 so that it moves to the outer surface of the blanking pipeline 204. Then, reverse-tighten the hand-tightening bolts again to fix the moved telescopic pipeline 205 on the outer surface of the blanking pipeline 204, preventing the telescopic pipeline 205 from sliding automatically and affecting the subsequent rotation of the cover plate 501 to the top of the extraction pool 301. By injecting water into the filter barrel 302, the concrete particles can be mixed with a certain amount of water to form a concrete slurry. A water reducing agent is previously poured into the reagent barrel 401 through the liquid injection pipe 408. During the mixing process, the liquid extraction pump 402 is started, and the water reducing agent in the reagent barrel 401 is pumped into the liquid outlet pipe 406 through the liquid extraction pipe 403, and then the water reducing agent is conveyed into the extraction pool 301. The transparent observation window 404 and the scale line 405 facilitate the staff to observe the change in the conveying amount of the water reducing agent. When an appropriate amount of the water reducing agent is conveyed, the liquid extraction pump 402 is timely turned off to prevent the over-conveyance or under-conveyance of the water reducing agent, affecting the subsequent effect. At the same time, the first motor 308 is controlled to start through the PLC controller 9, and under the adjustment of the frequency converter 8, the rotation speed of the first motor 308 is adjusted to make it rotate slowly. The rotation of the output end of the first motor 308 drives the rotating rod 312 and the turntable 313 to rotate slowly. The L-shaped rod 314 is clamped in the L-shaped groove 315 and the limiting groove 316. When the turntable 313 rotates, it drives the L-shaped rod 314 to rotate, further driving the filter barrel 302 to rotate slowly, mixing and stirring the water, water reducing agent and concrete particles in the extraction pool 301 and the filter barrel 302. The three are in full contact, and the water reducing agent can chemically react or physically act with the surface of the cement particles to form a stable adsorption film.Under the action of the membrane, the friction between cement particles is reduced, the internal cohesion between particles is decreased, making the particles easier to disperse and mix with water to form concrete slurry. The water reducer can form highly dispersed charges on the surface of cement particles, and electrostatic repulsion occurs between them, increasing the distance between particles, thus reducing the force that hinders particle dispersion and mixing, accelerating the hydration reaction of cement particles, improving the fluidity and plasticity of concrete, thereby accelerating the formation speed of concrete slurry, saving time, and improving work efficiency. Then, the solenoid valve 321 is opened, so that the cement slurry in the extraction tank 301 is discharged into the connecting pipe 306 through a plurality of drain pipes 305. Then, the cement slurry is discharged into the liquid storage tank 6 for storage, thus achieving the effect of extracting and recycling the cement slurry. After extracting the cement slurry, it can be used as raw material for recycled concrete or other cement products, reducing production costs and improving resource utilization efficiency. When most of the cement slurry is discharged from the extraction tank 301, the speed of the first motor 308 is increased by the frequency converter 8, driving the rotating rod 312, the turntable 313, the L-shaped rod 314 and the filter barrel 302 to rotate rapidly. Under the action of centrifugation, the remaining solid particles inside the filter barrel 302 are centrifugally filtered to separate the cement slurry and the solid particles. Before centrifugal separation, the forward and reverse motor 502 and the blower 503 can be started. The output end of the forward and reverse motor 502 drives the cover plate 501 to rotate. At the same time, the two clamping columns 507 slide in the two sliding holes 307, making the cover plate 501 rotate to the top of the extraction tank 301 to cover the top of the extraction tank 301, preventing the cement slurry from splashing out accidentally during the subsequent centrifugation process. During the centrifugal separation process, the blower 503 sucks external air into the air supply pipe 504, and then blows air into the filter barrel 302 through the air outlet hood 505, which can accelerate the evaporation of water in the solid particles inside the filter barrel 302, making the particles drier, helping to reduce the moisture content of the particles, improving the quality and stability of the particles, and preventing the solid particles from adhering together during the subsequent screening process, affecting the screening effect. When the extraction of the cement slurry is completed, the first motor 308 is turned off, and the forward and reverse motor 502 is started again to drive the cover plate 501 and the blower 503 to reset. Two handles are installed on the top of the filter barrel 302. By holding the handles and rotating the filter barrel 302, the L-shaped rod 314 rotates from the limiting groove 316 to the L-shaped rod 314. At this time, the filter barrel 302 loses the limit of the L-shaped rod 314. Then, the hook on the external lifting device is hung on the two handles, and then the external lifting device can take out the filter barrel 302 from the extraction tank 301, facilitating the staff to pour the solid particles in the filter barrel 302 into the screening device for screening, facilitating subsequent discharge, and reducing the impact and pollution of cement components on the environment. When the filter barrel 302 rotates, it drives the annular support plate 309 to rotate together. Under the rolling of a plurality of rolling balls 318, the friction is reduced, facilitating the smoother rotation of the filter barrel 302. When discharging the concrete in the construction waste, the concrete still contains cement components, which will cause pollution to the environment.Problems that are not conducive to the sustainable development of the environment.

During the mixing process, the liquid extraction pump (402) is started, and the water-reducing agent in the chemical agent barrel (401) is pumped into the liquid outlet pipe (406) through the liquid extraction pipe (403), and then the water-reducing agent is transported into the extraction tank (301). Through the transparent observation window (404) and the scale line (405), it is convenient for the staff to observe the change of the transported amount of the water-reducing agent.

The three are in full contact. The water-reducing agent can undergo chemical reactions or physical interactions on the surface of the cement particles to form a stable adsorption film. Under the action of the film, the friction between the cement particles is reduced, the internal cohesion between the particles is reduced, making the particles easier to disperse and mix with water to form concrete slurry. The water-reducing agent can form highly dispersed charges on the surface of the cement particles, and electrostatic repulsion occurs between them, increasing the distance between the particles, thereby reducing the force that hinders the dispersion and mixing of the particles, accelerating the hydration reaction of the cement particles, improving the fluidity and plasticity of the concrete, thus accelerating the formation speed of the concrete slurry, saving time and improving work efficiency; During the centrifugal separation process, the fan (503) pumps external air into the air supply pipe (504), and then blows air into the interior of the filter barrel (302) through the air outlet hood (505), which can accelerate the evaporation of water in the solid particles inside the filter barrel (302), make the particles drier, help reduce the moisture content of the particles, improve the quality and stability of the particles, and prevent the solid particles from adhering together during the subsequent screening process, affecting the screening effect.
