Description

Technical Field

[0001] This application relates to the technical field of concrete processing, and in particular to a concrete aggregate separation device. Background Technology

[0002] Concrete is one of the civil engineering materials used in building construction. Concrete is made by mixing aggregates, cementitious materials, water, and other substances in a specific ratio, followed by uniform mixing to form the final product. Based on the size of the aggregate particles furthest from the medium aggregate, concrete is divided into coarse aggregate concrete and fine aggregate concrete. Coarse aggregate concrete is suitable for large-volume structural components, such as foundations and pile caps. Fine aggregate concrete is suitable for structural components with high reinforcement density, such as beams and walls. Coarse aggregate consists of rock particles with a diameter greater than 4.75 mm. Fine aggregate consists of rock particles with a diameter less than 4.75 mm.

[0003] The aggregate separation equipment in related technologies uses a single screen for screening, which is prone to clogging during the aggregate separation process, resulting in reduced aggregate separation efficiency. Summary of the Invention

[0004] In order to improve aggregate separation efficiency, this application provides a concrete aggregate separation device.

[0005] This application provides a concrete aggregate separation device, which adopts the following technical solution:

[0006] A concrete aggregate separation device includes a fixed box with a receiving cavity inside. The receiving cavity contains a first screening mechanism for separating aggregates, a guide plate for collecting aggregates, a first crushing mechanism for crushing aggregates, and a second screening mechanism for separating aggregates. The receiving cavity includes a first vertical surface and a second vertical surface that are parallel to each other. The first screening mechanism includes a first mounting block disposed on the first vertical surface and a second mounting block disposed on the second vertical surface. A screening pipe is rotatably connected between the first mounting block and the second mounting block. The screening pipe faces... A fixing hole is provided on the end face of the first mounting block, and a screening hole communicating with the fixing hole is provided on the outer circumference of the screening tube. A discharge hole communicating with the fixing hole is provided on the lower end face of the second mounting block. A spiral blade located in the fixing hole is rotatably connected between the first mounting block and the second mounting block. The spiral blade is used to drive the aggregate to move towards the second mounting plate. A lifting assembly for lifting the aggregate is provided on the spiral blade. The lifting assembly includes a lifting plate. Both ends of the lifting plate along the axis of the screening tube are connected to the spiral blade. The guide plate is located below the screening tube.

[0007] By adopting the above technical solution, the rotation of the spiral blades can drive the aggregate in the screening tube to move towards the second mounting block. At the same time, the lifting plate lifts the aggregate and drops it from a height, which can better separate coarse and fine aggregates. This allows the fine aggregate to pass through the screening holes to the outside of the screening tube, and then be discharged from the fixed box by the guide plate. The large aggregate particles are crushed by the first crushing mechanism. In addition, the screening tube generates centrifugal force during rotation, which can better throw the aggregate in the screening holes out of the screening holes, so as to prevent the aggregate from clogging the screening holes and improve the aggregate separation efficiency.

[0008] Optionally, a first operating tube is rotatably connected to the first mounting block. The first operating tube extends out of the fixed box in a direction away from the second mounting block. A first operating strip is provided on the outer circumferential surface of the first operating tube. The end face of the first operating strip away from the first operating tube is fixedly connected to the inner circumferential surface of the screening tube.

[0009] By adopting the above technical solution, the rotation of the first operating tube drives the rotation of the first operating bar, and the first operating bar drives the rotation of the screening tube, which facilitates the screening tube to throw out the aggregate in the screening hole.

[0010] Optionally, the spiral blades are fixedly connected to the inner circumferential surface of the screening tube, and the fixed box is provided with a first driving component for driving the screening tube to rotate.

[0011] By adopting the above technical solution, the first drive component is activated, causing the screening tube to rotate, which in turn drives the spiral blades to rotate.

[0012] Optionally, an operating roller is inserted through and rotatably connected to the first operating tube, and the spiral blade is fixedly connected to the outer circumferential surface of the operating roller. The first operating tube extends out of the fixed box in a direction away from the second mounting block. The fixed box is provided with a first driving component for driving the screen tube to rotate and a second driving component for driving the operating roller to rotate.

[0013] By adopting the above technical solution, the first drive component is started, causing the screening tube to rotate; the second drive component is started, causing the operating roller to rotate, and the operating roller drives the spiral blade to rotate, causing the aggregate to move towards the second mounting block.

[0014] Optionally, the first drive assembly includes a first inner magnet sleeved outside the first operating tube and a frame disposed on the side of the first fixed box. The first inner magnet is located outside the fixed box, and a first isolation cover is provided on the outer cover of the first inner magnet. The first isolation cover is connected to the fixed box, and a first outer magnet is rotatably connected to the outer cover. A driven gear ring is sleeved on the outer circumference of the first outer magnet. A first drive motor is disposed on the frame, and the output shaft of the first drive motor is meshed with a drive gear. The drive gear and the driven gear ring mesh with each other.

[0015] By adopting the above technical solution, the first drive motor drives the drive gear to rotate. Since the drive gear meshes with the driven gear ring, the drive gear drives the driven gear ring and the first outer magnet to rotate. The first outer magnet drives the first inner magnet and the first operating tube to rotate through magnetic force. The first operating tube drives the screening tube to rotate.

[0016] Optionally, the first drive assembly includes a first isolation cover disposed on the side of the first fixed box, the first isolation cover covering the first operating tube, the operating roller passing through the first isolation cover and extending outside the first isolation cover, the second drive assembly including a second inner magnet sleeved on the operating roller, the second inner magnet being covered by a second isolation cover, the second isolation cover being connected to the first isolation cover, a support frame being disposed on the end face of the second isolation cover away from the first isolation cover, a second drive motor being mounted on the support frame, the output shaft of the second drive motor being connected to a second outer magnet, and the second isolation cover being located inside the second outer magnet.

[0017] By adopting the above technical solution, the second drive motor drives the second outer magnet to rotate, and the second outer magnet drives the second inner magnet and the operating roller to rotate through magnetic force, and the operating roller drives the spiral blade to rotate.

[0018] Optionally, the end face of the lifting plate facing the axis of the screening tube is provided with a plurality of lifting blades, which are bent in the direction of rotation of the screening tube.

[0019] By adopting the above technical solution, the setting of the lifting plates can effectively separate coarse and fine aggregates, allowing the fine aggregates to fall from the lifting plates first, followed by the coarse aggregates, which facilitates the fine aggregates to pass through the screening holes on the screening pipe.

[0020] Optionally, the first crushing mechanism is disposed below the second mounting block, the inner wall of the accommodating cavity includes two third vertical surfaces, the first crushing mechanism includes two first pressure rollers rotatably connected between the two third vertical surfaces and a first operating component for driving the two first pressure rollers to rotate, a first pressing block is disposed on the outer circumferential surface of the first pressure rollers, and the two first pressure rollers rotate in opposite directions.

[0021] By adopting the above technical solution, the aggregate falls from the discharge hole between the two first pressure rollers. The first operating component drives the first pressure rollers to rotate, and the aggregate is crushed by the first pressure blocks on the two first pressure rollers.

[0022] Optionally, the second screening mechanism includes a first screening plate rotatably connected between two third vertical surfaces, a first operating plate for collecting aggregate, and a first actuating component for driving the first screening plate to swing. The first screening plate has a first through hole, and the first operating plate is disposed between the two third vertical surfaces and located below the first screening plate.

[0023] By adopting the above technical solution, the first actuating component drives the first screening plate to swing up and down, so that the aggregate moves on the first screening plate, and the fine aggregate can fall onto the first operating plate through the first through hole.

[0024] Optionally, the first actuating component includes a first cam rotatably connected to the upper end of the third vertical surface, the first cam abutting against the lower end surface of the first screening plate.

[0025] By adopting the above technical solution, the first cam rotates, and because the first cam abuts against the lower end face of the first screening plate, the first screening plate swings up and down. On the one hand, this facilitates the movement of aggregate on the first screening plate, and on the other hand, it facilitates the aggregate to fall onto the first operating plate through the first through hole.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The rotation of the spiral blades can drive the aggregate in the screening tube to move towards the second mounting block. At the same time, the lifting plate lifts the aggregate and drops it from a height, which can better separate coarse and fine aggregates. Fine aggregates can pass through the screening holes to the outside of the screening tube, and then be discharged from the fixed box by the guide plate. Larger aggregates are crushed by the first crushing mechanism. In addition, the centrifugal force generated during the rotation of the screening tube can better throw the aggregate in the screening holes out of the screening holes, so as to prevent the aggregate from clogging the screening holes and improve the aggregate separation efficiency.

[0028] 2. The first operating component drives the two first pressure rollers to rotate, extruding and crushing the coarse aggregate. Attached Figure Description

[0086] Reference Figure 3 and Figure 4 When the second drive motor 285 is working, it drives the second outer magnet 284 to rotate. The second outer magnet 284 drives the second inner magnet 282 to rotate synchronously through magnetic force, thereby realizing the rotation of the operating roller 261, which in turn makes the spiral blade 26 rotate.

[0087] Reference Figure 3and Figure 4 The first drive motor 278 drives the screening tube 23 to rotate, and the second drive motor 285 drives the operating roller 261 to rotate.

The first outer magnet 274 drives the first inner magnet 271 and the screening tube 23 to rotate. The second drive motor 285 drives the second inner magnet 282, the spiral blade 26 and the lifting plate 291 to rotate through the second outer magnet 284. The rotation of the screening tube 23 and the spiral blade 26 transports and screens the aggregate.
