Description

Technical Field

[0001] This utility model relates to the field of material screening technology, and in particular to an automatic material screening and diversion device. Background Technology

[0002] A roller press mainly consists of two opposing, synchronously rotating extrusion rollers. Material is fed from above the rollers, and during the rotation of the rollers, the material is squeezed between the rollers and compacted and crushed under strong pressure. Currently, material generally enters the roller press directly without screening. However, when large particles are between the rollers, their larger size prevents the pressure from being distributed as evenly as that of smaller particles. This leads to excessive local stress on the roller surface, causing accelerated wear and shortening the roller's service life. Furthermore, uneven material size can result in large deviations in the roller gaps at both ends during the crushing process, preventing the formation of a stable material layer and causing vibration or shutdown. This not only affects the stable operation of the equipment but may also lead to equipment damage and increased downtime.

[0003] Based on the above situation, it is necessary to design an automatic material screening and diversion device to solve the above problems. Utility Model Content

[0004] This invention provides an automatic material screening and diversion device to solve the problem in the prior art where unevenly sized materials entering the roller press affect the operation of the equipment.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] An automatic material screening and diversion device includes a conveyor belt for conveying material to the input end of a roller press. A diverter is inclinedly arranged on the conveyor belt, and the angle between the length extension direction of the diverter and the conveying direction of the conveyor belt is acute. The diverter is used to apply an obstructive force to the material conveyed on the conveyor belt and divert the conveyed material.

[0007] Preferably, the diverting component includes a frame disposed above the conveyor belt and a plurality of idlers rotatably connected inside the frame, and there is space between two adjacent idlers for smaller materials to pass through.

[0008] Preferably, the multiple idlers are connected by a transmission belt, the bottom end of the idler abuts against the upper surface of the conveyor belt, and a drive motor with an output end connected to one of the idlers is provided above the frame.

[0009] Preferably, the diverting component includes a conveyor belt located outside two rotating drums, and the two rotating drums are connected by a transmission belt. One end of one of the rotating drums is connected to a drive motor, and there is a space between the lower end of the conveyor belt and the upper surface of the conveyor belt for smaller materials to pass through.

[0010] Preferably, an inclined discharge plate is connected to one side of the conveyor belt, and the discharge plate is located on the side where the angle between the diverter and the conveyor belt is acute.

[0011] Preferably, friction protrusions are connected to the outer side of the diverter.

[0012] The beneficial effects of this utility model are: when the conveyor belt conveys the material, when the material to be fed into the mill is conveyed to the diversion part, the material with uniform particle size passes smoothly, while the large piece of material is intercepted by the diversion part and automatically screened and diverted, falling from the discharge plate on one side for centralized collection and processing, ensuring that the material entering the roller press has a uniform particle size and improving the working effect of the roller press.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] Reference Figures 1-4 As shown, the automatic material screening and diversion device includes a conveyor belt 1. The output end of the conveyor belt 1 can be placed at the feed inlet of a roller press for conveying material to the input end of the roller press. A diverter 2 is inclinedly arranged on the conveyor belt 1, and the angle between the length extension direction of the diverter 2 and the conveying direction of the conveyor belt 1 is an acute angle β, such as preferably 45°. The diverter 2 is used to apply an obstructive force to the material conveyed on the conveyor belt 1, diverting the conveyed material. When a large volume of material is conveyed by the conveyor belt 1 and comes into contact with the diverter 2, an obstructive force is applied. The force applied to the material in the opposite direction to the movement of conveyor belt 1 hinders the material from continuing to move forward with conveyor belt 1. There is also a force perpendicular to the surface of conveyor belt 1, causing the material to tend to be lifted or have its original posture altered on conveyor belt 1. Smaller materials are not blocked by the diverter 2 and pass smoothly through it, entering the roller press with conveyor belt 1. This results in a more uniform volume of material entering the roller press, improving the efficiency of the roller press. The specific structure of the diverter 2 will be described below:

[0021] Reference Figure 1 As shown, the first embodiment provided by this utility model is as follows: the diverting component 2 includes a frame 3 disposed above the conveyor belt 1 and multiple idlers 31 rotatably connected inside the frame 3. The bottom end of the idler 31 can extend to contact the upper end surface of the conveyor belt 1, and there is space between two adjacent idlers 31 for smaller materials to pass through. The multiple idlers 31 are connected by a transmission belt 4. The frame 3 is provided with a drive motor 41 whose output end is connected to one of the idlers 31. The drive motor 41 drives one of the idlers 31 to rotate, and the transmission belt 4 drives it to rotate synchronously with the idler 31. When some larger materials are intercepted by the idler 31, the rotation of the idler 31 helps to move some of the intercepted larger volume materials to one side of the conveyor belt 1 by the rotational force of the idler 31, and drop them from the discharge plate 6 described below for centralized collection. The spacing between two adjacent idlers 31 can be adjusted according to the size of the materials to be separated and screened.

[0022] Reference Figure 2As shown, the second embodiment provided by this utility model is as follows: the diverting component 2 includes a conveyor belt 51 located outside two rotating drums 5, and the two rotating drums 5 are connected by a transmission belt 4. One end of one of the rotating drums 5 is connected to a drive motor 41. A certain space is left between the bottom end of the conveyor belt 51 and the conveyor belt 1 to allow smaller materials to pass through the diverting component 2, while larger materials are intercepted by the conveyor belt 51. Similar to the first embodiment, the drive force of the drive motor 41 can drive the conveyor belt 51 to rotate, thereby assisting in the discharge of the intercepted materials. However, unlike the first real-time method, some smaller materials can only pass through the space between the lower end of the conveyor belt 51 and the conveyor belt 1. For some flat but large-area materials, interception is not possible. In the first embodiment, some large-area but flat materials can be intercepted by the idler roller 31, but some irregularly shaped materials may get stuck between two adjacent idler rollers 31.

[0023] Furthermore, friction protrusions 7 are connected to the outer side of the diverter 2. When the diverter 2 rotates, it will generate an additional pushing force on the large material that is intercepted. Since the material is intercepted on one side of the diverter 2, the contact part between the material and the diverter 2 will be subject to friction in the direction of movement of the diverter 2 to help discharge the intercepted material from the discharge plate 6.

[0024] Furthermore, one side of the conveyor belt 1 is connected to an inclined discharge plate 6, and the discharge plate 6 is located on the side where the angle between the diverter 2 and the conveyor belt 1 is acute. In actual use, a collection bin for holding large-volume materials can be set below the discharge plate 6 for centralized collection for subsequent processing.
