Description

Technical Field

[0001] This utility model relates to the field of ceramsite screening technology, and in particular to a ceramsite screening and grading device. Background Technology

[0002] Expanded clay aggregate, as the name suggests, is ceramic-like granules. Most expanded clay aggregate is round or oval-shaped, but some imitation crushed stone expanded clay aggregate is not round or oval-shaped, but rather irregularly shaped like crushed stone. The shape of expanded clay aggregate varies depending on the manufacturing process. Its surface is a hard outer shell, which is ceramic or glazed, serving to prevent water and air leakage and giving the expanded clay aggregate high strength. Because there are many raw materials used to produce expanded clay aggregate, there are many varieties, and therefore many colors.

[0003] Existing expanded clay aggregates produce particles of varying sizes during production. Therefore, before use, an expanded clay aggregate sieve is needed to separate the particles of different sizes. Chinese utility model patent, authorized announcement number "CN117259186A", discloses an expanded clay aggregate sieve, including a sieve base. A feed frame is fixedly connected to the upper side wall of the sieve base, and a sieve chamber is opened at the top of the sieve base. An inclined multi-stage sieve plate is fixedly connected to the sieve chamber, and multiple feed hoppers are connected to the bottom of the multi-stage sieve plate. Multiple feed ports are opened on the front wall of the sieve base, each communicating with a feed hopper. A motor is fixedly connected to the side wall of the feed frame.

[0004] The above-mentioned technical solution uses a reciprocating control plate to allow the ceramsite to be screened to fall intermittently in batches onto the multi-stage screening plate and spread evenly. The reciprocating impact of the balls on the multi-stage screening plate causes vibration, making it less prone to clogging and thus improving the screening effect of the ceramsite. However, the above technical solution still has certain drawbacks. Due to the different sizes of holes on the surface of the multi-stage screening plate, the reciprocating impact of the balls on the multi-stage screening plate, and the inclined setting of the multi-stage screening plate, when the impact force of the balls on the multi-stage screening plate is too great, some smaller ceramsite particles may roll directly down the multi-stage screening plate and fall into the hopper at their lower end, mixing with larger ceramsite particles and affecting the screening effect. Therefore, this utility model proposes a novel solution. Utility Model Content

[0035] Please see Figure 1-4This utility model provides a technical solution: a ceramsite screening and grading device, including a ceramsite screening device 1, a ceramsite screening unit, the ceramsite screening unit being disposed inside the ceramsite screening device 1, the ceramsite screening unit including four screening plate connecting shafts 5, all four screening plate connecting shafts 5 being fixedly connected inside the ceramsite screening device 1, the surfaces of the four screening plate connecting shafts 5 being rotatably connected to a first ceramsite screening plate 6, a second ceramsite screening plate 7, a third ceramsite screening plate 8, and a ceramsite guide plate 9 respectively, the ceramsite screening device 1 being provided with a first U-shaped frame 12, the third ceramsite screening plate 6, the fourth ceramsite screening plate 7, the fifth ceramsite screening plate 8, and the sixth ceramsite guide plate 9. First connecting shafts 13 are fixedly connected to the left and right sides of the first ceramsite screening plate 6 and the third ceramsite screening plate 8, and all four first connecting shafts 13 are rotatably connected to the first U-shaped frame 12. A second U-shaped frame 14 is provided inside the ceramsite screening equipment 1. Second connecting shafts 15 are fixedly connected to the left and right sides of the second ceramsite screening plate 7 and the ceramsite guide plate 9, and all four second connecting shafts 15 are rotatably connected to the second U-shaped frame 14. Four ceramsite baffles 10 are provided inside the ceramsite screening equipment 1, and multiple ceramsite baffle strips 11 are provided inside the ceramsite screening equipment 1.

[0036] The ceramsite screening device also includes a drive motor 16, which is fixedly connected to the front end of the ceramsite screening equipment 1. The output end of the drive motor 16 is fixedly connected to a rotating shaft 17, which is rotatably connected to the ceramsite screening equipment 1. Two cams 18 are fixedly connected to the surface of the rotating shaft 17.

[0037] The first ceramsite screening plate 6, the second ceramsite screening plate 7, the third ceramsite screening plate 8, and the ceramsite guide plate 9 are staggered inside the ceramsite screening equipment 1. Screening holes are opened on the surfaces of the first ceramsite screening plate 6, the second ceramsite screening plate 7, and the third ceramsite screening plate 8, and the size of the screening holes decreases from top to bottom. Four ceramsite baffles 10 are fixedly connected to the surfaces of the corresponding first ceramsite screening plate 6, the second ceramsite screening plate 7, the third ceramsite screening plate 8, and the ceramsite guide plate 9, respectively. Multiple ceramsite baffles 11 are fixedly connected to the surfaces of the corresponding first ceramsite screening plate 6, the second ceramsite screening plate 7, and the third ceramsite screening plate 8, respectively. The cross-section of the multiple ceramsite baffles 11 is a right-angled triangle, and the inclined surfaces of the multiple ceramsite baffles 11 are all located on the side away from the corresponding screening plate connecting shaft 5.

[0038] The ceramsite screening equipment 1 is equipped with four ceramsite discharge guide troughs 3 inside. The four ceramsite discharge guide troughs 3 are all fixedly inclined inside the ceramsite screening equipment 1. Four ceramsite discharge pipes 4 are fixedly connected to the left side of the ceramsite screening equipment 1. The four ceramsite discharge guide troughs 3 are all connected to the corresponding ceramsite discharge pipes 4.

[0039] The bottom of the ceramsite screening equipment 1 is fixedly connected to a ceramsite hopper 2.

[0040] When using this device, the ceramsite to be screened is first added to the inside of the ceramsite screening equipment 1 from the ceramsite hopper 2. When the ceramsite falls into the inside of the ceramsite screening equipment 1, it is screened by the ceramsite baffle 10. Since the screening holes on the surface of the ceramsite baffle 10 are large, it is easy to leave the largest ceramsite particles on the surface of the ceramsite baffle 10, and then they fall onto the corresponding ceramsite discharge guide chute 3 and are discharged from the corresponding ceramsite discharge pipe 4. The remaining ceramsite falls from the screening holes of the ceramsite baffle 10 onto the surface of the second ceramsite screening plate 7 inside the ceramsite screening equipment 1.

[0041] The ceramsite will be screened again by the second ceramsite screening plate 7, so that medium-sized ceramsite particles are left on the surface of the second ceramsite screening plate 7 and then fall onto the corresponding ceramsite discharge guide chute 3. The remaining ceramsite particles fall from the screening holes on the surface of the second ceramsite screening plate 7 onto the surface of the third ceramsite screening plate 8 inside the ceramsite screening equipment 1.

[0042] Finally, the third ceramsite screening plate 8 screens the ceramsite. Small ceramsite particles fall from the surface of the third ceramsite screening plate 8 onto the corresponding ceramsite discharge guide chute 3 and are discharged from the corresponding ceramsite discharge pipe 4. The remaining smallest ceramsite particles fall from the screening holes on the surface of the third ceramsite screening plate 8 onto the surface of the ceramsite guide plate 9.

[0043] The ceramsite falling onto the surface of the ceramsite guide plate 9 is guided by the ceramsite guide plate 9 and the ceramsite discharge guide trough 3, making it easier to be discharged from the bottom ceramsite discharge pipe 4.

[0044] During the screening of ceramsite, the drive motor 16 is started to drive the rotating shaft 17 to rotate. The rotating shaft 17 drives the cam 18 to rotate, so that the cam 18 applies pressure to the first U-shaped frame 12 and the second U-shaped frame 14, causing the first U-shaped frame 12 and the second U-shaped frame 14 to move in the vertical direction. Since the first U-shaped frame 12 and the first connecting shaft 13 are respectively connected to the corresponding first ceramsite screening plate 6, second ceramsite screening plate 7, third ceramsite screening plate 8 and ceramsite guide plate 9 through the first connecting shaft 13 and the second connecting shaft 15, it is convenient to drive the first ceramsite screening plate 6, second ceramsite screening plate 7, third ceramsite screening plate 8 and ceramsite guide plate 9 to swing up and down around the corresponding screening plate connecting shaft 5, so that the ceramsite on the surface of the first ceramsite screening plate 6, second ceramsite screening plate 7, third ceramsite screening plate 8 and ceramsite guide plate 9 will vibrate to a certain extent, preventing the ceramsite from clogging the screening holes and improving screening efficiency and effect.

[0045] Ceramsite baffles 10 are installed on the surfaces of the first ceramsite screening plate 6, the second ceramsite screening plate 7, the third ceramsite screening plate 8, and the ceramsite guide plate 9 to prevent ceramsite from flowing out from the edges of these plates during screening, thus affecting screening efficiency. Ceramsite baffle strips 11 are installed on the surfaces of the first ceramsite screening plate 6, the second ceramsite screening plate 7, and the third ceramsite screening plate 8 to block the ceramsite during screening, prolonging the time the ceramsite spends on these plates. The baffle strips 11 on the screening mesh surface can guide the flow of ceramsite on the screening mesh, preventing ceramsite from sliding or accumulating directly during screening, thereby improving screening efficiency.

[0046] By tilting the ceramsite discharge guide chute 3, the inclined ceramsite discharge guide chute 3 plays a role in guiding the flow of ceramsite inside the ceramsite screening equipment 1, ensuring that the ceramsite can flow along a predetermined path, so that the ceramsite can be discharged from the corresponding ceramsite discharge pipe 4. This can prevent the ceramsite from accumulating during the screening process, ensure the smooth progress of the screening process, and improve the screening efficiency.

[0047] Furthermore, the first ceramsite screening plate 6, the second ceramsite screening plate 7, the third ceramsite screening plate 8, and the ceramsite guide plate 9 swing around the corresponding screening plate connecting shaft 5 under the drive of the cam 18. The swinging of the first ceramsite screening plate 6, the second ceramsite screening plate 7, and the third ceramsite screening plate 8 can make the ceramsite form a highly layered state on its surface, which helps to better distinguish particles of different sizes, thereby improving screening efficiency and accuracy, reducing the accumulation and clogging of ceramsite on the screen, and ensuring the continuity and stability of the screening process.

[0048] By oscillating the first ceramsite screening plate 6, the second ceramsite screening plate 7, and the third ceramsite screening plate 8, and by setting ceramsite baffles 10 on the surfaces of the first ceramsite screening plate 6, the second ceramsite screening plate 7, the third ceramsite screening plate 8, and the ceramsite guide plate 9, it is possible to prevent ceramsite from flowing out from the edges of the first ceramsite screening plate 6, the second ceramsite screening plate 7, the third ceramsite screening plate 8, and the ceramsite guide plate 9 during the screening process, thereby affecting the screening efficiency. Ceramsite baffles 11 are set on the surfaces of the first ceramsite screening plate 6, the second ceramsite screening plate 7, and the third ceramsite screening plate 8 to block the ceramsite during the screening process, prolonging the time the ceramsite spends on the surfaces of the first ceramsite screening plate 6, the second ceramsite screening plate 7, and the third ceramsite screening plate 8. The ceramsite baffles 11 on the surface of the screening mesh can guide the flow of ceramsite on the screening mesh, preventing the ceramsite from directly sliding or accumulating during the screening process, thereby improving the screening efficiency.

[0049] Working principle: When using this device, the ceramsite to be screened is first added to the inside of the ceramsite screening equipment 1 from the ceramsite hopper 2. When the ceramsite falls into the inside of the ceramsite screening equipment 1, it is screened by the ceramsite baffle 10. Since the screening holes on the surface of the ceramsite baffle 10 are large, it is easy to leave the largest ceramsite particles on the surface of the ceramsite baffle 10, and then they fall onto the corresponding ceramsite discharge guide chute 3 and are discharged from the corresponding ceramsite discharge pipe 4. The remaining ceramsite falls from the screening holes of the ceramsite baffle 10 onto the surface of the second ceramsite screening plate 7 inside the ceramsite screening equipment 1.

[0050] The ceramsite will be screened again by the second ceramsite screening plate 7, so that medium-sized ceramsite particles are left on the surface of the second ceramsite screening plate 7 and then fall onto the corresponding ceramsite discharge guide chute 3. The remaining ceramsite particles fall from the screening holes on the surface of the second ceramsite screening plate 7 onto the surface of the third ceramsite screening plate 8 inside the ceramsite screening equipment 1.

[0051] Finally, the third ceramsite screening plate 8 screens the ceramsite. Small ceramsite particles fall from the surface of the third ceramsite screening plate 8 onto the corresponding ceramsite discharge guide chute 3 and are discharged from the corresponding ceramsite discharge pipe 4. The remaining smallest ceramsite particles fall from the screening holes on the surface of the third ceramsite screening plate 8 onto the surface of the ceramsite guide plate 9.

[0052] The ceramsite falling onto the surface of the ceramsite guide plate 9 is guided by the ceramsite guide plate 9 and the ceramsite discharge guide trough 3, making it easier to be discharged from the bottom ceramsite discharge pipe 4.

[0053] During the screening of ceramsite, the drive motor 16 is started to drive the rotating shaft 17 to rotate. The rotating shaft 17 drives the cam 18 to rotate, so that the cam 18 applies pressure to the first U-shaped frame 12 and the second U-shaped frame 14, causing the first U-shaped frame 12 and the second U-shaped frame 14 to move in the vertical direction. Since the first U-shaped frame 12 and the first connecting shaft 13 are respectively connected to the corresponding first ceramsite screening plate 6, second ceramsite screening plate 7, third ceramsite screening plate 8 and ceramsite guide plate 9 through the first connecting shaft 13 and the second connecting shaft 15, it is convenient to drive the first ceramsite screening plate 6, second ceramsite screening plate 7, third ceramsite screening plate 8 and ceramsite guide plate 9 to swing up and down around the corresponding screening plate connecting shaft 5, so that the ceramsite on the surface of the first ceramsite screening plate 6, second ceramsite screening plate 7, third ceramsite screening plate 8 and ceramsite guide plate 9 will vibrate to a certain extent, preventing the ceramsite from clogging the screening holes and improving screening efficiency and effect.

[0054] Ceramsite baffles 10 are installed on the surfaces of the first ceramsite screening plate 6, the second ceramsite screening plate 7, the third ceramsite screening plate 8, and the ceramsite guide plate 9 to prevent ceramsite from flowing out from the edges of these plates during screening, thus affecting screening efficiency. Ceramsite baffle strips 11 are installed on the surfaces of the first ceramsite screening plate 6, the second ceramsite screening plate 7, and the third ceramsite screening plate 8 to block the ceramsite during screening, prolonging the time the ceramsite spends on these plates. The baffle strips 11 on the screening mesh surface can guide the flow of ceramsite on the screening mesh, preventing ceramsite from sliding or accumulating directly during screening, thereby improving screening efficiency.

[0055] By tilting the ceramsite discharge guide chute 3, the inclined ceramsite discharge guide chute 3 plays a role in guiding the flow of ceramsite inside the ceramsite screening equipment 1, ensuring that the ceramsite can flow along a predetermined path, so that the ceramsite can be discharged from the corresponding ceramsite discharge pipe 4. This can prevent the ceramsite from accumulating during the screening process, ensure the smooth progress of the screening process, and improve the screening efficiency.

[0056] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
