Description

Technical Field

[0001] This utility model relates to the field of sorting technology, specifically a four-separation combined air classifier for sand sorting. Background Technology

[0002] Sand crushing and processing is the process of converting raw materials such as rocks, ores or construction waste into uniformly sized construction sand or industrial sand through crushing, screening, and sand making processes.

[0003] The prior art, disclosed in CN212397013U, discloses a sand sorting device for building concrete production, including a sorting box. The upper and lower ends of the sorting box are respectively fixedly connected to a feed hopper and a sand outlet pipe. A pair of parallel drive shafts are provided inside the sorting box. A pair of drive motors connected to the drive shafts are fixedly installed at the rear end of the sorting box. A mounting roller is fixedly installed on the outside of the drive shaft. Multiple sorting blades distributed in a ring array are fixedly connected to the outer surface of the mounting roller.

[0004] After processing, sand particles are classified into three different grades based on their particle size: fine sand, medium sand, and coarse sand. To ensure effective classification according to grade, specialized equipment is required for sorting. Furthermore, the sand particles generated during processing contain a large amount of stone powder. This stone powder not only affects the quality of the sand particles but may also adversely impact subsequent use. Therefore, appropriate equipment is needed to thoroughly separate this stone powder from the sand particles to ensure the purity and performance of the final sand particles. To this end, a four-separation combined air classifier for sand sorting is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a four-separation combined air classifier for sand sorting, so as to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a four-part combined air classifier for sand sorting, comprising supporting legs, a sorting box fixedly mounted on the supporting legs, a top cover fixedly mounted on the upper end of the sorting box, a hopper fixedly mounted on the top cover, a screening mechanism installed inside the sorting box, the screening mechanism comprising a supporting spring fixedly mounted on the bottom of the sorting box, a vibrating plate fixedly mounted on the upper end of the supporting spring, a vibrating motor fixedly mounted on the bottom of the vibrating plate, a positioning frame fixedly mounted on the vibrating plate, a coarse screen and a fine screen fixedly mounted on the positioning frame, and a separation mechanism connected to one end of the sorting box.

[0007] Preferably, a fine sand chute is fixedly installed below the fine screen, a coarse sand chute is fixedly installed below the coarse screen, and a medium sand chute is fixedly installed below the coarse sand chute.

[0008] Preferably, bolts are connected to the positioning frame, and both the fine screen and the coarse screen are fixedly installed on the positioning frame by bolts.

[0009] Preferably, one end of the support spring is fixedly installed at the bottom of the sorting box, and the other end of the support spring is fixedly installed on the vibration plate. One end of the sorting box has three holes, and the ends of the fine sand chute, coarse sand chute and medium sand chute all extend out of the sorting box through the holes.

[0010] Preferably, the separation mechanism includes a sand discharge pipe fixedly installed at one end of the sorting box. The sand discharge pipe has a fine sand inlet, a coarse sand inlet, and a medium sand inlet on one side. A volute is fixedly installed at the upper end of the sand discharge pipe. A cross-flow fan is rotatably installed inside the volute. A drive motor is fixedly installed at one end of the volute, and the output end of the drive motor is fixedly installed on one end of the cross-flow fan. An air pipe is connected to the volute, and a bag filter is connected to the end of the air pipe.

[0011] Preferably, a bearing is installed on the volute, and the cross-flow fan blade is rotatably mounted inside the volute via the bearing.

[0012] Preferably, the bag filter and the volute are connected by an air pipe, and a booster fan is connected to the air pipe.

[0013] Preferably, the end of the fine sand chute extends into the sand discharge pipe through the fine sand inlet, the end of the coarse sand chute extends into the sand discharge pipe through the coarse sand inlet, and the end of the medium sand chute extends into the sand discharge pipe through the medium sand inlet.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this application, after the vibrating motor is started, it drives the vibrating plate to vibrate, which in turn drives the coarse and fine screens to vibrate. During the vibration process, the fine screen screens screen the material, separating out fine sand, which is then transported to the sand discharge pipe via a fine sand chute. The coarse screen screens out medium sand, which is then transported to the sand discharge pipe via a medium sand chute. The coarse sand is transported to the sand discharge pipe via a coarse sand chute. Through the above process, the separation of fine, medium, and coarse sand is achieved.

[0015] 2. In this application, the drive motor can be started when the fine sand, medium sand, and coarse sand fall down the sand discharge pipe. After the drive motor is started, it will drive the cross-flow fan to rotate, thereby disturbing the airflow through the sand discharge pipe and blowing the stone powder in the raw material into the bag filter. The stone powder blown into the bag filter will be filtered out, thus achieving the separation of stone powder from the raw material. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a four-separation combined air classifier for sand sorting, including a support leg 1, a sorting box 2 fixedly installed on the support leg 1, a top cover 3 fixedly installed on the upper end of the sorting box 2, a hopper 4 fixedly installed on the top cover 3, a screening mechanism 5 installed inside the sorting box 2, and a separation mechanism 6 connected to one end of the sorting box 2.

[0020] Working principle: Hopper 4 can store raw materials. After the gate at the bottom of hopper 4 is pulled out, the raw materials will fall onto the fine screen 506. Screening mechanism 5 can screen out fine sand, medium sand and coarse sand, and separation mechanism 6 can separate stone powder from the raw materials.

[0021] Example 2: Figure 2 and Figure 3As shown, the screening mechanism 5 includes a support spring 501 fixedly installed at the bottom of the sorting box 2. A vibrating plate 502 is fixedly installed at the upper end of the support spring 501. A vibrating motor 503 is fixedly installed at the bottom of the vibrating plate 502. A positioning frame 504 is fixedly installed on the vibrating plate 502. A coarse screen 505 and a fine screen 506 are fixedly installed on the positioning frame 504. A fine sand chute 507 is fixedly installed below the fine screen 506. A coarse sand chute 508 is fixedly installed below the coarse screen 505. A medium sand chute 509 is fixedly installed below the coarse sand chute 508. Bolts are connected to the positioning frame 504. Both the fine screen 506 and the coarse screen 505 are fixedly installed on the positioning frame 504 by bolts.

[0022] Specifically, after the vibration motor 503 is started, it will drive the vibrating plate 502 to vibrate. After the vibrating plate 502 vibrates, it will drive the coarse screen 505 and the fine screen 506 to vibrate.

[0023] When the fine screen 506 vibrates, it filters out fine sand, which is then conveyed to the sand discharge pipe 609 via the fine sand chute 507. When the coarse screen 505 vibrates, it filters out medium sand, which is then conveyed to the sand discharge pipe 609 via the medium sand chute 509. Coarse sand, on the other hand, is conveyed to the sand discharge pipe 609 via the coarse sand chute 508, thus achieving the separation of fine, medium, and coarse sand.

[0024] Example 3: Figure 2 and Figure 4 As shown, the separation mechanism 6 includes a sand discharge pipe 609 fixedly installed at one end of the sorting box 2. The sand discharge pipe 609 has a fine sand inlet 606, a coarse sand inlet 607, and a medium sand inlet 608 on one side. A volute 603 is fixedly installed at the upper end of the sand discharge pipe 609. A cross-flow fan blade 605 is rotatably installed inside the volute 603. A drive motor 604 is fixedly installed at one end of the volute 603, and the output end of the drive motor 604 is fixedly installed on one end of the cross-flow fan blade 605. An air pipe 602 is connected to the volute 603. A bag filter 601 is connected to the end of the air pipe 602. A bearing is installed on the volute 603, and the cross-flow fan blade 605 is rotatably installed inside the volute 603 through the bearing.

[0025] Specifically, as fine, medium, and coarse sand smoothly falls along the sand discharge pipe 609, the drive motor 604 can be activated. Once activated, the drive motor 604 quickly drives the connected cross-flow fan 605 to rotate at high speed. This rotational motion effectively disturbs the surrounding airflow, allowing it to pass smoothly through the sand discharge pipe 609. During this process, stone powder mixed in with the raw materials is carried by the strong airflow and ultimately blown into the bag filter 601. The stone powder entering the bag filter 601 undergoes efficient filtration inside, thus being completely separated. In this way, the stone powder in the raw materials is effectively removed, ensuring the smooth progress of subsequent processes and improving product quality.

[0026] Working principle: Hopper 4 can store raw materials. After the gate at the bottom of hopper 4 is pulled out, the raw materials will fall onto the fine screen 506. When the raw materials fall, the vibration motor 503 can be started. After the vibration motor 503 is started, it will drive the vibrating plate 502 to vibrate. After the vibrating plate 502 vibrates, it will drive the coarse screen 505 and the fine screen 506 to vibrate. When the fine screen 506 vibrates, it will screen out fine sand. The screened fine sand will be transported to the sand discharge pipe 609 through the fine sand chute 507. When the coarse screen 505 vibrates, it will screen out medium sand. The screened medium sand will be transported to the sand discharge pipe 609 through the medium sand chute 509. The coarse sand will be transported to the sand discharge pipe 609 through the coarse sand chute 508, thereby separating fine sand, medium sand and coarse sand. Furthermore, when fine sand, medium sand, and coarse sand fall down along the sand discharge pipe 609, the drive motor 604 can be started. After the drive motor 604 is started, it will drive the cross-flow fan 605 to rotate, thereby disturbing the airflow through the sand discharge pipe 609, and sending the stone powder in the raw material into the bag dust collector 601. The stone powder blown into the bag dust collector 601 will be filtered out, thereby separating the stone powder in the raw material.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
