Description

Technical Field

[0001] This utility model belongs to the field of natural sand air separation technology, specifically a machine-made natural sand air separation chamber. Background Technology

[0002] A machine-made natural sand air classifier is an industrial device primarily used for particle size separation and quality optimization of natural sand. By controlling the wind force and airflow distribution, sand particles of different sizes are classified according to requirements, while simultaneously removing dust and impurities from the sand, ensuring the uniformity and cleanliness of the finished sand.

[0003] Existing technologies still have the following shortcomings: If the sand particles are too densely distributed during feeding, multiple problems will arise during the wind separation process. On the one hand, small sand particles may be blocked by large sand particles and unable to move smoothly under the action of wind, thus affecting the separation effect of natural sand; on the other hand, dense sand particles will cause local airflow to be obstructed, weakening the force of wind on small sand particles, making it difficult for small sand particles to move along the expected trajectory, ultimately resulting in unsatisfactory separation effect of large and small sand particles and inaccurate particle size classification. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a machine-made natural sand air separation chamber, which solves the problems of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a machine-made natural sand air separation chamber, comprising a chamber body, a hopper fixedly connected to the side wall of the chamber body, a fixed plate fixedly connected to the hopper, a rotating shaft rotatably connected to the fixed plate, one end of the rotating shaft passing through the fixed plate and coaxially fixedly connected to a bevel gear, the other end of the rotating shaft being provided with crushing blades, a motor and a vertical plate fixedly connected to the chamber body, the output end of the motor passing through the vertical plate and coaxially fixedly connected to a pulley and a bevel gear, the bevel gear and the bevel gear meshing with each other, a protective cover provided on the fixed plate, and both the bevel gear and the bevel gear being located inside the protective cover.

[0006] As a further embodiment of this utility model: a guide plate is fixedly connected to the side wall of the cabin, a fixing block is fixedly connected to the guide plate, a groove is provided at the bottom of the fixing block, and a rake plate is slidably connected in the groove.

[0007] As a further embodiment of this utility model: a pair of telescopic rods are fixedly connected to one end of the rake plate, the output end of the telescopic rods is fixedly connected to the side wall of the groove, and a spring is sleeved on the side wall of the telescopic rods, with the two ends of the springs abutting against the groove and the rake plate respectively.

[0008] As a further embodiment of this utility model: a second rotating shaft is rotatably connected to the inner wall of the cabin, and a second pulley and a rotating wheel are coaxially fixedly connected to the second rotating shaft, and a belt is sleeved between the first pulley and the second pulley.

[0009] As a further embodiment of this utility model: a fixing rod is fixedly connected to the other end of the rake plate, the fixing rod passes through the fixing block and is slidably connected thereto, one end of the fixing rod is rotatably connected to a connecting rod, and one end of the connecting rod is rotatably connected to the eccentric position of the rotating wheel.

[0010] As a further embodiment of this utility model: the interior of the cabin is provided with a coarse material box, a fine material box and a platform, a blower is provided on the platform, and a cabin door is provided on one side of the cabin.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model is equipped with a vibrating rake plate. When the sand particles flow down along the guide plate, the vibration generated by the rake plate can effectively break the dense accumulation of sand particles, causing the sand particles that were originally gathered together to disperse from each other. This avoids the situation in the air separation process where small sand particles cannot be effectively separated because they are blocked by large sand particles, thus improving the accuracy of natural sand separation and ensuring the reliability of the separation effect. 2. This utility model is equipped with crushing blades, which can break up sand clumps when they fall with the material flow, thus preventing sand clumps from falling directly into the coarse material box without treatment and contaminating the pure sand that has been sorted.

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] like Figures 1-5 As shown, this utility model provides a technical solution: The machine-made natural sand air separation chamber includes a chamber body 1. A hopper 2 is fixedly connected to the side wall of the chamber body 1. A fixed plate 3 is fixedly connected to the hopper 2. A rotating shaft 4 is rotatably connected to the fixed plate 3. One end of the rotating shaft 4 passes through the fixed plate 3 and is coaxially fixedly connected to a bevel gear 5. The other end of the rotating shaft 4 is provided with a crushing blade 6. A motor 7 and a vertical plate 8 are fixedly connected to the chamber body 1. The output end of the motor 7 passes through the vertical plate 8 and is coaxially fixedly connected to a pulley 9 and a bevel gear 10. The bevel gear 5 and the bevel gear 10 mesh with each other. A protective cover 23 is provided on the fixed plate 3. Both the bevel gear 5 and the bevel gear 10 are located inside the protective cover 23. Specifically, the motor 7 is started, and the output end of the motor 7 drives the pulley 9 and the bevel gear 10 to rotate. The bevel gear 10 drives the bevel gear 5 to rotate through the meshing relationship, thereby driving the shaft 4 to rotate. The crushing blades 6 also rotate. At this time, the raw material is poured into the hopper 2. When the sand particles in the raw material fall, they will be crushed by the crushing blades 6, which prevents the sand particles from falling directly into the coarse material box 20 without treatment and causing pollution to the pure sand particles that are separated. A guide plate 11 is fixedly connected to the side wall of the chamber 1. A fixing block 12 is fixedly connected to the guide plate 11. A groove is provided at the bottom of the fixing block 12. A rake plate 13 is slidably connected in the groove. A pair of telescopic rods 14 are fixedly connected to one end of the rake plate 13. The output end of the telescopic rod 14 is fixedly connected to the side wall of the groove. A spring is sleeved on the side wall of the telescopic rod 14. The two ends of the spring abut against the groove and the rake plate 13 respectively. A rotating shaft 15 is rotatably connected to the inner wall of the chamber 1. 5 is coaxially fixedly connected to pulley 16 and wheel 17. A belt is sleeved between pulley 9 and pulley 16. The other end of rake plate 13 is fixedly connected to a fixing rod 18. The fixing rod 18 passes through the fixing block 12 and is slidably connected to it. One end of the fixing rod 18 is rotatably connected to a connecting rod 19. One end of the connecting rod 19 is rotatably connected to the eccentric position of wheel 17. The interior of the chamber 1 is provided with a coarse material box 20, a fine material box 21 and a platform. A blower 22 is provided on the platform. Specifically, pulley 9 drives pulley 16 to rotate via a belt, which in turn drives shaft 15 to rotate. Wheel 17 also rotates, and wheel 17 drives one end of connecting rod 19 to rotate. Since fixed rod 18 is slidably connected to fixed block 12 and cannot rotate, the other end of connecting rod 19 can only drive fixed rod 18 to move back and forth in the horizontal direction. In conjunction with telescopic rod 14 and spring, the sand particles falling onto guide plate 11 are raked evenly, causing the sand particles that were originally gathered together to disperse. After the sand particles flow out of guide plate 11, they are blown by the wind force of blower 22. The heavier sand particles fall directly into coarse material box 20 under the action of gravity, while the lighter sand particles are blown into fine material box 21 by the airflow, completing the material separation. After the material separation is completed, the hatch can be opened to take out the finished sand.

[0016] The working principle of this utility model is as follows: When the motor 7 is started, the output end of the motor 7 drives the pulley 9 and the bevel gear 10 to rotate. The bevel gear 10 drives the bevel gear 5 to rotate through the meshing relationship, thereby driving the shaft 4 to rotate. The crushing blades 6 also rotate. At this time, the raw material is poured into the hopper 2. When the sand particles in the raw material fall, they will be crushed by the crushing blades 6, which prevents the sand particles from falling directly into the coarse material box 20 without treatment and causing pollution to the pure sand particles that are separated. Belt pulley 19 drives belt pulley 26 to rotate via a belt, which in turn drives shaft 25 to rotate. Wheel 17 also rotates, and wheel 17 drives one end of connecting rod 19 to rotate. Since fixed rod 18 is slidably connected to fixed block 12 and cannot rotate, the other end of connecting rod 19 can only drive fixed rod 18 to move back and forth in the horizontal direction. With the help of telescopic rod 14 and spring, the sand particles falling on guide plate 11 are raked evenly, causing the sand particles that were originally gathered together to disperse. After the sand particles flow out of guide plate 11, they are blown by the wind force of blower 22. The heavier sand particles fall directly into coarse material box 20 under the action of gravity, while the lighter sand particles are blown into fine material box 21 by the airflow, completing the material separation. After the material separation is completed, the hatch can be opened to take out the finished sand.

[0017] The preferred embodiments of the present invention have been described in detail above. However, the present invention 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 invention.
