[0002] Controlling the stone powder content is a crucial step in manufactured sand production. Excessive stone powder content not only affects the quality of the manufactured sand but also causes numerous inconveniences in subsequent processing and use. Traditionally, stone powder content is controlled primarily through dust collection equipment, but the effect is limited and it's difficult to achieve ideal stone powder separation. Especially at the chute between the manufactured sand conveyor belt and the humidifier, stone powder easily accumulates due to the falling and conveying of the sand, further complicating stone powder control. Utility Model Content

[0003] The purpose of this invention is to provide a stone powder separation device to improve the control effect of stone powder in manufactured sand and ensure the quality of manufactured sand.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stone powder separation device for manufactured sand, the stone powder separation device comprising a box body, a plurality of impact plates disposed within the box body, a fan fixed on the box body, and an exhaust pipe installed on the box body, the plurality of impact plates being fixed on the back plate of the box body, an air inlet being provided on the back plate, the air inlet being located below the impact plates, the fan being installed on the air inlet, the bottom of the box body being the manufactured sand outlet, the exhaust pipe being connected to a dust collector, and the top of the box body being the feed inlet for the manufactured sand to enter.

[0021] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Please see Figures 1 to 3 The stone powder separation device shown in a preferred embodiment of this application is used for manufactured sand. The stone powder separation device includes a housing 10, a plurality of impact plates 20 disposed within the housing 10, a fan 30 fixed to the housing 10, an exhaust pipe 40 mounted on the housing 10, and a herringbone plate 50 fixed within the housing 10. The impact plates 20 are fixed to a back plate 14 of the housing 10, and the back plate 14 has an air inlet (unlabeled) located below the impact plates 20. The fan 30 is mounted on the air inlet. The bottom of the housing is a manufactured sand outlet (unlabeled), and the top is a feed inlet 12 for manufactured sand to enter. The herringbone plate 50 is disposed between the manufactured sand outlet and the impact plates 20. The exhaust pipe is connected to a vacuum cleaner to suck out the stone powder from the housing.

[0023] By employing the stone powder separation device of this application, the control effect of stone powder in manufactured sand can be improved, ensuring the quality of manufactured sand. Specifically, when the manufactured sand enters the housing 10, as it passes through several impact plates 20, the stone powder in the manufactured sand is separated through the cooperation of the impact plates 20 and the fan 30. Simultaneously, the stone powder flows out of the housing 10 through the exhaust pipe 40 connected to the vacuum cleaner, thereby effectively achieving the separation effect of stone powder in the manufactured sand, reducing the stone powder content in the manufactured sand, and thus improving the quality of the manufactured sand. Please refer to [link / reference]. Figure 4 , Figure 4 The test results of the manufactured sand before and after using the stone powder separation device of this application are shown.

[0024] In this embodiment, a channel 13 for the flow of manufactured sand is formed inside the housing 10. A plurality of impact plates 20 are arranged along the flow direction of the manufactured sand, with a spacing of 200mm between adjacent impact plates 20. This channel 13 effectively ensures that the manufactured sand can pass through the device in an orderly and efficient manner for separation, helping to reduce clogging and material accumulation, and improving separation efficiency. The impact plates 20, arranged along the flow direction of the manufactured sand, can effectively impact and disperse the sand, helping to separate stone powder and other lightweight components from the sand, making the separation process more uniform and efficient. The impact plates 20 include an end impact plate 21 located at the very end of all the impact plates 20. In the horizontal direction, the end impact plate 21 is inclined downwards, while the remaining impact plates 20 are arranged upwards. The downward inclination of the end impact plate 21 helps to further separate residual stone powder and other lightweight components in the manufactured sand and guides them towards the herringbone plate 50, reducing the amount of residual stone powder and improving separation quality. The upward arrangement of the remaining impact plates 20 allows for better impact and dispersion of the manufactured sand, and also helps to lift the stone powder and other lightweight components upwards, making it easier for the fan 30 to blow them away. In a specific embodiment, the impact plates 20 are straight-line impact plates 20, and there are six impact plates 20. The impact plates 20 are made of Mn65 spring steel to increase the impact force when the manufactured sand falls, promoting the separation of stone powder from the manufactured sand.

[0025] To ensure that the manufactured sand has a certain impact force and dispersion effect during flow, and to help reduce the accumulation and blockage of manufactured sand in channel 13 and improve separation efficiency, the angle formed between the back plate 14 and the horizontal plane is 70°-50°, preferably 60°. The angle formed between the end impact plate 21 and the back plate 14 is 50°-40°, preferably 45°; the remaining impact plates are arranged perpendicular to the back plate 14.

[0026] In this embodiment, the housing 10 includes a main housing 101 forming the flow channel 13 and a side housing 102 disposed on one side of the main housing 101. The baffle plate 20 and the fan 30 are disposed on the main housing 101, and the air duct 40 is disposed on the top of the side housing 102, in the forward projection direction ( Figure 1 In the direction indicated by the middle arrow A, the projection of the accommodating cavity 15 within the side housing 102 covers the area where several of the striking plates 20 are located, and extends to the air inlet and the herringbone plate 50. By covering the area where several striking plates 20 are located with the projection of the accommodating cavity 15 within the side housing 102, and particularly extending to the air inlet and the herringbone plate 50, it helps protect the striking plates 20 from interference and damage from the external environment, and also reduces noise and dust leakage, improving the quality of the working environment. Furthermore, in an alternative embodiment, the main housing 101 and the side housing 102 can be detachably connected, thus realizing a modular design of the device, facilitating installation, maintenance, and upgrades, while also improving the flexibility and scalability of the device.

[0027] The herringbone plate 50 includes a first plate and a second plate disposed opposite to each other, mirror images of each other. The upper ends of the first plate and the second plate are fixed, and the included angle formed between the first plate and the second plate is between 45° and 65°, preferably 58°. When the manufactured sand reaches the herringbone plate 50 via the impact plate 20, it impacts the herringbone plate 50 to further promote the separation of stone powder and manufactured sand. The first plate and the second plate are made of spring steel.

[0028] After prolonged use, dust and stone powder may accumulate on the impact plate 20. To facilitate cleaning, a dust removal port (unlabeled) is provided on the side wall 15 of the main housing 101. A dust removal door 60 is pivotally connected to the main housing, and the dust removal door 60 opens or closes the dust removal port; in the lateral orthographic projection direction ( Figure 2 In the direction indicated by the middle arrow B, the projection of the dust removal port at least partially covers the impact plate 20.

[0029] The stone powder separation device is located between the feed inlet of the manufactured sand conveyor belt and the humidifier. In actual use, it can utilize the chute between the feed inlet and the humidifier, i.e., the chute's housing 10 serves as the housing 10 of this stone powder separation device. As the manufactured sand falls from the conveyor belt into the housing 10, it continuously impacts the impact plate 20 during its descent, and the fan 30 stirs up dust, which is then extracted through the exhaust pipe 40 connected to the vacuum cleaner. In actual use, the stone powder content in the manufactured sand can be effectively controlled by adjusting the power of the fan 30 and the vacuum cleaner, reducing the amount of stone powder before the sand enters the humidifier. By utilizing the chute between the feed inlet and the humidifier, the vacuum cleaner can be shared with the manufactured sand production line; in practice, only the vacuum pipe needs to be installed, thus helping to reduce modification costs.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
