Description

TECHNICAL FIELD

[0002] In chemical production, the screening of chemical materials is a key link to ensure product quality and smooth production process. Traditional chemical material screening equipment often has low screening efficiency, poor precision and other problems, which is difficult to meet the needs of modern chemical production for efficient and accurate screening. For example, some screening equipment cannot effectively separate materials of different particle sizes, resulting in uneven product quality. Some equipment has poor stability during operation and frequently fails, affecting production progress.

[0003] In traditional material screening equipment, the angle of the screening hopper is usually designed as fixed type. When facing a work scene with large amount of material processing, a large amount of material flows into the screening hopper. Since the angle of the screening hopper is not adjustable, the residence time of the material on the screen plate is too short, making it difficult for the material to be fully screened. Many materials are discharged from the screening hopper without undergoing effective screening process, resulting in reduced screening effect.

[0004] Therefore, the skilled person in the art proposes a chemical material screening machine to solve the problems raised in the background. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0021] The embodiments of the present application will be further described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0022] Example 1: as shown in the accompanying Figure 1 and accompanying Figure 2 : the present application provides a chemical material screening machine, including support frame 1, connecting assembly and drive assembly;

[0023] The top wall of the support frame 1 is fixed with the feed hopper 3, the bottom surface of the feed hopper 3 is connected with the lower hopper 2, the inner wall of the support frame 1 is provided with the screening hopper 5, the position of the lower hopper 2 corresponds to the screening hopper 5, the top surface of the screening hopper 5 is fixedly provided with the sieve plate 13, and the end of the screening hopper 5 is provided with the discharge port 15; the material is received by the feed hopper 3 and guided into the screening hopper 5 through the lower hopper 2, and the screening function is realized by controlling the cyclic displacement of the screening hopper 5;

[0024] The connecting assembly includes first top frame 401, second top frame 402, first bottom frame 601, second bottom frame 602, hydraulic cylinder 7 and hinged rod 8; the first top frame 401 and the second top frame 402 are two groups, the first top frame 401 and the second top frame 402 are symmetrically fixed to the two inner walls of the support frame 1, and the first bottom frame 601 and the second bottom frame 602 are symmetrically fixed to the two outer walls of the screening hopper 5; the hydraulic cylinder 7 is hingedly installed between the first top frame 401 and the first bottom frame 601, and the hinged rod 8 is hingedly installed between the second top frame 402 and the second bottom frame 602;

[0025] As shown in the accompanying Figure 2 and accompanying Figure 3 : the drive assembly includes drive motor 10, connecting frame 501, rotating rod 502 and traction rod 504; the rotating rod 502 is rotatably installed in the inner wall of the support frame 1, the connecting frame 501 is fixed on the bottom surface of the screening hopper 5, the rotating frame 503 is installed on the circumferential side of the rotating rod 502, and the traction rod 504 is hingedly installed between the rotating frame 503 and the connecting frame 501; the drive motor 10 controls the rotation of the rotating rod 502.

[0026] A fixed platform 9 is fixedly installed on the side wall of the support frame 1. The drive motor 10 is installed on the upper surface of the fixed platform 9. An active wheel 11 is installed at one end of the rotating rod 502. A transmission belt 12 is installed between the drive motor 10 and the active wheel 11. The drive motor 10 drives the rotating rod 502 to rotate through the transmission belt 12. The rotating rod 502 drives the rotating frame 503 to rotate cyclically. The rotating frame 503 can pull the traction rod 504 to move back and forth, thereby realizing the back and forth movement of the screening bucket 5 and achieving a stable screening function.

[0027] The hydraulic cylinder 7 has a first connecting seat 701 fixed at its telescopic end and a second connecting seat 702 fixed at its other end. The first connecting seat 701 is hinged to the first top frame 401, and the second connecting seat 702 is hinged to the first base frame 601. The hydraulic cylinder 7 can extend and retract stably. When the hydraulic cylinder 7 extends and retracts, the inclination angle of the material discharge end of the screening hopper 5 changes, thereby ensuring that the material can be kept on the surface of the screen plate 13. This effectively avoids the situation where the material stays for too short a time when there is too much material, thus greatly ensuring the stability of screening.

[0028] As can be seen from the above, when the material screening operation is carried out, the material first enters the feed hopper 3, and then, relying on gravity and the guiding effect of the discharge hopper 2, it falls accurately into the screening hopper 5, laying the foundation for the subsequent screening process.

[0029] When the hydraulic cylinder 7 extends or retracts, it drives one end of the screening bucket 5 to rise or fall through the first connecting seat 701 and the second connecting seat 702, thereby changing the inclination angle of the material discharge end of the screening bucket 5. Through such angle changes, the residence time of the material on the screen plate 13 can be effectively adjusted to meet different material quantities and screening requirements.

[0030] After the drive motor 10 starts, it drives the rotating rod 502 to rotate through the transmission belt 12. A rotating frame 503 is installed around the rotating rod 502, and a connecting frame 501 is fixed to the bottom of the screening hopper 5. A traction rod 504 is hinged between the rotating frame 503 and the connecting frame 501. The rotation of the rotating rod 502 drives the rotating frame 503 to rotate in a circular motion. During the rotation, the rotating frame 503 pulls the traction rod 504 to make a reciprocating linear displacement, thereby pulling the screening hopper 5 to move back and forth. The reciprocating motion of the screening hopper 5 causes the material to continuously roll and move on the screen plate 13, realizing the function of fully screening the material.

[0031] Example 2: Based on Example 1, a receiving channel 14 is fixed at the end of the screen plate 13. A discharge port 1401 is provided at one end of the receiving channel 14. The inner surface of the receiving channel 14 has a continuous inclined plane structure. The screened material falls into the receiving channel 14 along the inclined angle of the screen plate 13 and under its own gravity. Then, it is discharged through the discharge port 1401 along the inclined plane of the inner surface of the receiving channel 14, thereby completely separating it from the qualified material discharged from the discharge port 15.

[0032] As can be seen from the above, the receiving channel 14 can receive the material screened off the surface of the screen plate 13, and the discharge port 1401 can separate the material from the discharge port 15 to avoid material mixing.
