Description

Technical Field

[0001] This utility model relates to the field of concrete waste technology, and in particular to a pretreatment device for recycled aggregates from concrete waste that separates from residual cement slurry. Background Technology

[0002] In the process of processing concrete waste, concrete sand and gravel separators not only improve the recycling rate of resources, but also significantly reduce environmental pollution. The separated sand and gravel can be used as recycled aggregates and reused in concrete production, effectively reducing the exploitation of natural resources. At the same time, cement slurry can be reused or discharged in compliance with regulations after treatment, avoiding pollution to the environment caused by waste slurry.

[0003] Traditional methods of concrete waste disposal have significant drawbacks. The energy consumption during the process is high, and cement paste remains on the surface of some aggregates after disposal. This residual cement paste can seriously interfere with the formation of the internal structure of new concrete, greatly affecting the strength and bonding performance of the new concrete, making it difficult to guarantee the quality of the new concrete. Utility Model Content

[0004] This utility model discloses a pretreatment device for recycled aggregates from concrete waste that removes residual cement slurry, aiming to solve the technical problems of high energy consumption in traditional concrete waste treatment and residual cement slurry on the surface of some aggregates, which affects the strength and bonding performance of new concrete.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A residual cement slurry-separated concrete waste recycled aggregate pretreatment device includes a separation tank. A slurry separation component is installed on the separation tank. The slurry separation component includes a servo motor. The power output shaft of the servo motor is connected to a drive gear via a coupling. The bottom end of the drive gear is movably connected to the front end of the separation tank. A linkage gear ring is movably connected to the outer side of the drive gear. A telescopic tube is fixedly connected to the inner side of the linkage gear ring. A separation ball tank is fixedly connected to the outer side of the telescopic tube. Symmetrical connecting frames are movably connected to the outer side of the telescopic tube. A telescopic rod is fixedly connected to the front end of one connecting frame, and a telescopic spring is fixedly connected to the front end of another connecting frame. The front ends of the telescopic rod and the telescopic spring are fixedly connected to the inner side of the separation tank. A telescopic drive rod is fixedly connected to the front end of the other connecting frame, and the outer side of the telescopic drive rod is movably connected to the outer side of the separation tank.

[0007] By incorporating a detachment bucket and a slurry detachment assembly, surface slurry detachment is achieved from concrete waste. A servo motor drives a drive gear to rotate, which meshes with a linkage gear ring, causing the linkage gear ring to rotate around the drive gear. A telescopic tube is fixedly connected to the inner side of the linkage gear ring, rotating with its movement. Simultaneously, the outer side of the telescopic tube is movably connected to the inner front end of the detachment bucket, providing support and guiding the rotation. A detachment ball bucket, fixedly connected to the other end of the telescopic tube, also rotates, stirring and tumbling the concrete waste within. This achieves surface slurry detachment from the concrete waste. Symmetrical connecting frames on the outer side of the telescopic tube provide auxiliary support and stability. When the surface of the concrete waste... After the mud separation is completed, the telescopic drive rod starts working and extends outward. As the telescopic drive rod extends, it pushes the connecting frame and the connected telescopic pipe and separation ball barrel to move outward. At the same time, the telescopic rod is compressed under the action of the telescopic drive rod, and the telescopic spring is also compressed, preparing for subsequent reset. The automatic opening and closing port opens, and the separation ball barrel gradually moves out of the separation barrel until it is directly above the rectangular hole of the treatment box. When the separation ball barrel is directly above the rectangular hole of the treatment box, it opens, and the separated concrete aggregate falls from the separation ball barrel onto the drying plate inside the treatment box under the action of gravity, completing the transfer process of concrete aggregate. During the process, the concrete waste is fully tumbled and stirred in the separation ball barrel, which can efficiently achieve surface mud separation and improve treatment efficiency and quality.

[0008] In a preferred embodiment, a symmetrical fixing ring frame is fixedly connected to the inner side of the detachment barrel, the fixing ring frame is located in front of the detachment ball barrel, an annular water pipe is fixedly connected to the inner side of the fixing ring frame, multiple water spray heads are fixedly connected to the outer side of the annular water pipe, and an inlet pipe is fixedly connected to the outer side of the annular water pipe. The outer side of the inlet pipe is fixedly connected to the outer side of the detachment barrel. An automatic opening and closing port is fixedly connected to the side of the detachment barrel near the detachment ball barrel. A support is fixedly connected to the outer side of the detachment barrel, and a processing box is fixedly connected to the bottom end of the support. A rectangular hole is opened at the top of the processing box. Fixing members are fixedly connected to both ends of the inner side of the processing box. A heating and drying pipe is fixedly connected to the inner side of each fixing member. A drying plate is fixedly connected to the inner side of the processing box, and the drying plate is located between the symmetrical perforations. A discharge pipe is fixedly connected to the side of the processing box away from the perforations, and the discharge pipe is located below the drying plate.

[0009] The concrete aggregate processing system, equipped with an automatic opening and closing port, support, processing box, discharge pipe, annular water pipe, spray nozzles, inlet pipe, heating and drying pipe, fixing components, drying plate, suction pipe, and fixed ring frame, involves the concrete aggregate entering the detachment sphere through a telescopic pipe. A servo motor drives the drive gear, which meshes with a linkage gear ring, causing the linkage gear ring to rotate the telescopic pipe and the detachment sphere. The concrete aggregate tumbles within the detachment sphere. Simultaneously, the inlet pipe introduces water into the annular water pipe, which is then sprayed from multiple nozzles to wash the concrete aggregate in the detachment sphere, cleaning the surface sludge. The fixed ring frame provides stable support for the annular water pipe, ensuring stability during the spraying process. After the sludge is cleaned, the automatic opening and closing port opens, the telescopic drive rod extends, and the connecting frame, telescopic pipe, and detachment sphere are activated. The detachment drum moves outward until it is directly above the rectangular hole at the top of the processing box. The detachment drum opens, and the detached concrete aggregate falls from the detachment drum onto the drying plate inside the processing box under gravity. The heating and drying pipe inside the retaining component is activated to heat and dry the concrete aggregate on the drying plate. The drying plate is used to support the concrete aggregate, ensuring it is heated evenly to achieve the drying effect. After drying, the suction pipe starts working, using suction to draw the concrete aggregate from the drying plate through the perforations onto the grading component. The grading component grades the drawn concrete aggregate, classifying it according to different specifications and requirements. The discharge pipe on the side of the processing box away from the perforations is used to discharge the graded concrete aggregate for subsequent storage or reuse operations.

[0010] In a preferred embodiment, a grading and processing component is provided inside the processing box. The grading and processing component includes a motor frame, the front end of which is fixedly connected to the outside of the processing box. A drive motor is fixedly connected to the outside of the motor frame, and the power output shaft of the drive motor is connected to a rotating rod via a coupling. The outside of the rotating rod is movably connected to the outside of the processing box. A rotating shaft is fixedly connected to the front end of the rotating rod, and a belt is movably connected to the outside of the rotating shaft. A movable shaft is movably connected to the inner side of one end of the belt. An inlet is fixedly connected to the inner side of the movable shaft. The front end of the inlet is movably connected to one end of a suction pipe located below. A screening barrel is fixedly connected to the rear end of the inlet, and an outlet is fixedly connected to the rear end of the screening barrel. The rear end of the outlet is movably connected to the front end of the outlet pipe.

[0011] Equipped with a grading and processing component, the drive motor is mounted on a motor frame, which is securely connected to the outside of the processing box. When grading and screening of the dried concrete aggregate is required, the drive motor is first turned on to rotate the rotating rod. The rotating rod is movably connected to the outside of the processing box, ensuring stable power transmission. The rotating shaft connected to the front end of the rotating rod rotates accordingly, and the rotating shaft drives the movable shaft to rotate via a belt. The movable shaft is fixedly connected to the feed inlet, and the front end of the feed inlet is movably connected to the suction pipe below. When the movable shaft rotates, the feed inlet begins to operate. At this time, the suction pipe draws the concrete aggregate from the drying plate into the feed inlet, and the concrete aggregate drawn into the feed inlet enters the screening process. The screening barrel rotates along with the feed inlet. During the rotation of the screening barrel, the concrete aggregate is screened according to different particle sizes or specifications using the mesh or internal structure of the screening barrel. Smaller particle sizes are screened out first through the mesh or specific structure of the screening barrel, while larger particle sizes remain in the screening barrel for further screening. The screened concrete aggregate is discharged from the discharge port connected to the rear end of the screening barrel. The rear end of the discharge port is movably connected to the discharge pipe. The graded and screened concrete aggregate is discharged from the processing box through the discharge pipe, completing the entire grading and screening process, so that the concrete aggregate of different grades can be processed or used separately in the future.

[0012] As can be seen from the above, the residual cement slurry separation type concrete waste recycled aggregate pretreatment device provided by this utility model has the technical effect of enabling the concrete waste to be fully tumbled and mixed, efficiently achieving surface slurry separation, and improving processing efficiency and quality.

[0024] Working principle: During concrete aggregate processing, the concrete aggregate enters the release spherical barrel 605 through the telescopic pipe 604. The servo motor 601 is activated, driving the drive gear 602 to rotate. The drive gear 602 meshes with the linkage gear ring 603, causing the linkage gear ring 603 to drive the telescopic pipe 604 and the release spherical barrel 605 to rotate. The concrete aggregate tumbles inside the release spherical barrel 605.

The fixing ring frame 15 provides stable support for the annular water pipe 7, ensuring stability during the water spraying process.

Above the rectangular hole at the top of the treatment box 4, the detachment ball barrel 605 opens. Under the action of gravity, the detached concrete aggregate falls from the detachment ball barrel 605 onto the drying plate 13 inside the treatment box 4. The heating and drying pipe 11 inside the retaining member 12 is activated to heat and dry the concrete aggregate on the drying plate 13. The drying plate 13 is used to support the concrete aggregate, so that it is heated evenly to achieve the drying effect. After drying, the suction pipe 14 starts to work, using suction to suck the concrete aggregate on the drying plate 13 through the perforation to the grading and processing component 9. The grading and processing component 9 grades the sucked concrete aggregate, classifying it according to different specifications and requirements. The discharge pipe 5 on the side of the treatment box 4 away from the perforation is used to discharge the graded concrete aggregate for subsequent storage or reuse operations.
