Description

Technical Field

[0001] This utility model relates to the field of screening devices, and in particular to a high-efficiency sand screening device. Background Technology

[0002] Sand usually refers to fine sand grains, which are commonly used in construction and concrete manufacturing. In some regions, the word can also refer to sand or sandy soil. Sand needs to be screened before use to remove impurities.

[0003] A search revealed Chinese Patent Publication No. CN221433846U, which discloses a sand screening device. The device includes a mixing tank with a mixing chamber. A mounting cover is connected to the upper side of the mixing chamber, and the mounting cover has a through-feed inlet. A through-outlet is located on the lower side of the mixing chamber. A rotating structure is located below the mounting cover. A flat filter screen is placed on the inner wall of the mixing chamber below the rotating structure, and the rotating structure abuts against the flat filter screen. A lower rotating shaft is located below the flat filter screen in the mixing chamber, and a lifting device is connected to the upper side of the lower rotating shaft. The upper end of the lifting device abuts against the flat filter screen. This invention achieves synchronous shaking of the filter screen from both the upper and lower sides through the lifting device of the lower rotating shaft and the rotating structure abutting against the flat filter screen. This disperses clumps of sand while preventing sand from splashing, ensuring screening quality and improving screening efficiency.

[0004] Although the above-mentioned device uses a rotating structure to abut against the flat filter screen, achieving synchronous shaking of the filter screen from top to bottom, which can disperse clumps of sand and prevent sand from splashing, the device can only send out the screened sand. The impurities removed after screening will still remain on the flat filter plate or conical filter hopper. The subsequent cleaning of these impurities is also time-consuming and laborious, making it impractical. Therefore, a high-efficiency sand screening device is proposed to solve the above problems. Utility Model Content

The screen plates and guide plates are inclined and fixedly connected to the discharge ports. The vibration component includes two mounting blocks, which are fixedly connected to the base plate. A motor is fixedly connected to the front side of the mounting block located at the front. A connecting shaft is fixedly connected to the output end of the motor.

[0033] 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.

[0034] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a high-efficiency sand screening device, comprising a housing 1 for connecting various components. Multiple dispersing plates 2 are fixedly connected to the upper part of the housing 1 to disperse the material and prevent clumping, which would affect the screening effect. A guide plate 4 is fixedly connected to the bottom of the housing 1 for discharging the material. Multiple auxiliary components 5 are provided at the lower part of the housing 1 for supporting the housing 1 and coordinating with its vibration. A vibration component 6 is provided at the lower part of the housing 1 to drive the housing 1 to vibrate. A base plate 7 is provided at the lower part of the housing 1 for connecting various components.

[0035] Furthermore, the outer casing 1 has discharge ports 11 on the front, left and right sides for discharging materials. Both sides of the discharge ports 11 are fixedly connected to baffles 12 for guiding the materials to a certain extent. The screen plate 3 and the guide plate 4 are inclined to facilitate the discharge of materials. The screen plate 3 and the guide plate 4 are fixedly connected to the discharge ports 11. Both the screen plate 3 and the guide plate 4 extend a portion out of the discharge ports 11 to guide the materials.

[0036] like Figure 4 - Figure 5 As shown, multiple dispersing plates 2 are arranged in an alternating inclined manner to disperse materials. Dispersing blocks 21 are provided on both the left and right sides of the dispersing plates 2, and the number of dispersing blocks 21 is multiple. The dispersing blocks 21 are arranged in an alternating manner. Two screen plates 3 are fixedly connected to the middle of the outer shell 1 to screen materials. The screen plates 3 located at the bottom have a larger mesh size than the screen plates 3 located at the top. Multiple baffles 31 are provided on the top surface of the screen plates 3 to block the materials to a certain extent, thereby increasing the time that the materials stay on the screen plates 3, so that the materials can be screened more thoroughly.

[0037] Please see Figure 6 - Figure 7The vibration assembly 6 includes two mounting blocks 61, which are used to connect various components. The mounting blocks 61 are fixedly connected to the base plate 7. A motor 62 is fixedly connected to the front side of the mounting block 61, which is used to provide power to the assembly. A connecting shaft 63 is fixedly connected to the output end of the motor 62, which is used to connect various components. The connecting shaft 63 passes through and is rotatably connected to the mounting block 61. A vibrating roller 64 is fixedly connected to the outside of the connecting shaft 63, which contacts the bottom of the outer shell 1. The vibrating roller 64 is set in an elliptical cylindrical shape, which can drive the outer shell 1 to vibrate up and down when it rotates.

[0038] Furthermore, the auxiliary component 5 includes a hollow column 51, which is used to connect various components. The hollow column 51 is fixedly connected to the base plate 7. A connecting rod 52 is slidably connected inside the hollow column 51, which is used to connect the fixing block 54. A spring 53 is fixedly connected between the connecting rod 52 and the hollow column 51, which is used to cooperate with the vibration of the outer shell 1. A fixing block 54 is fixedly connected to the top of the connecting rod 52, which is used to fix the auxiliary component 5 to the outer shell 1. The fixing block 54 is fixedly connected to the outer shell 1.

[0039] Working principle: First, the motor 62 is turned on, and the motor 62 will drive the connecting shaft 63 to rotate. When the connecting shaft 63 rotates, it will drive the vibrating roller 64 to rotate. Since the vibrating roller 64 is elliptical cylindrical, when the vibrating roller 64 rotates, it will drive the upper part of the outer shell 1 in contact with it to move up or down, thereby causing the outer shell 1 to vibrate. When the outer shell 1 moves, the connecting rod 52 connected to the outer shell 1 through the fixing block 54 will be driven to move up or down. The connecting rod 52 will intermittently compress the spring 53 in the hollow column 51. The auxiliary component 5 can also help the outer shell 1 maintain a certain stability while vibrating.

[0040] Then, the sand to be screened is poured into the outer shell 1 through the opening at the top of the outer shell 1. When the sand enters the outer shell 1, it will first pass through multiple dispersing plates 2. Due to the vibration of the outer shell 1, the sand will vibrate between the dispersing plates 2. At this time, if there are lumps of material, they will collide with the dispersing blocks 21 on the dispersing plates 2, thereby helping to disperse the material. The dispersed material will fall into the screen plate 3 below and be screened downward through the screen holes on the screen plate 3. Since the screen plate 3 is inclined, the impurities and other materials that are screened and retained on the upper part of the screen plate 3 will be guided through the screen plate 3 to the discharge port 11 and discharged. At the same time, since the screen plate 3 is equipped with multiple baffles 31, the baffles 31 can block the movement of the material to a certain extent, thereby ensuring that the material stays on the screen plate 3 for a longer time, so that the material can be screened more thoroughly. Finally, the qualified sand will fall onto the guide plate 4 at the bottom and be discharged by the guide plate 4 through the discharge port 11.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
