Description

Technical Field

[0001] The utility model relates to the field of screening equipment, in particular to a screening device for particle preparation. Background Art

[0002] Screening devices separate particles based on their size, specific gravity, charge, magnetism, and other powder properties. Using a perforated screen to separate mixed materials into various size classes is called screening. Because particles vary in mass, a screening device is required for greater convenience and improved performance. Screening devices are widely used in many industrial sectors, including the chemical, food, metallurgical, and environmental protection industries.

[0003] In the industrial sector or chemical industry, there are various existing screening devices. Among them, the rapid screening device using a height difference will block particles that are larger than the distance between the inclined baffle and the bottom plate. The blocked particles slide down from the side along the inclined baffle. This screening method is simple and fast, but when a large number of large particles are blocked, the driving force for particle movement will be insufficient, and accumulation will occur, which is inconvenient in the production process. Therefore, it is necessary to provide a screening device for particle preparation to solve the above problems. Utility Model Content

Support wheels 14 are provided at the bottom ends of the connecting shaft 12 and the driving shaft 11.

[0027] For further information, see Figure 1 As shown, in order to support the screener, a frame 19 is provided below the bottom plate 1 , and a fixed foot 20 is provided below the frame 19 .

[0028] For further information, see Figure 4 As shown, in order to increase the shaking generated after the screener is started, a spring 21 is provided between the base plate 1 and the frame 19, and a hook 22 is provided under the base plate 1, and the hook 22 is connected to the spring 21.

[0030] The working principle of the utility model is: when a particle preparation screening device is working, Figure 1 As shown, the three baffles are distributed from top to bottom. The distance between the bottom of the baffle 9 at the top and the bottom plate 1 is the largest, and the distance between the baffle 9 at the bottom and the bottom plate 1 is the smallest. First, the material is placed in the space between the top baffle 9 and the side plate 2. The bottom plate vibrator 3 is set on the side plate 2. After starting, the bottom plate 1 vibrates, and the qualified material will slide through the three baffles 9 to the discharge port 17 and be discharged along the discharge port baffle 16.

[0031] Among them, the height difference of the three baffles 9 from the side plate 2 to the discharge port 17 decreases in sequence, and is divided into a high baffle, a middle baffle and a low baffle. Through the three baffles 9, multiple materials of different specifications are obtained in one screening. The large particles screened are blocked by different baffles 9 and then contact the transmission belt 13. At the same time, the micro motor 15 is started again to drive the drive shaft 11 to rotate the transmission belt 13. At the same time, the transmission belt 13 drives the connecting shaft 12 to rotate. The support wheel 14 supports the drive shaft 11, the transmission belt 13 and the connecting shaft 12. In conjunction with the inclined baffle 9, the baffle 9 is connected to the transmission belt 13. 3 The large particles of material in contact move along the direction of movement of the transmission belt 13, enter the guide plate 7 through different discharge ports 6 and are discharged into the discharge collector 8 for materials of different specifications. It is worth noting that each discharge port 6 is provided with a corresponding baffle to prevent particles from being discharged directly from the discharge port 6 without being screened during the screening process. When the screener is in operation, a hook 22 and a spring 21 are connected between the bottom plate 1 and the frame 19 to reduce the shaking of the screener during operation. Fixed feet 20 and a metal plate 23 are provided under the frame 19 to increase the stability of the screener during operation.
