[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Embodiment: Please refer to Figures 1-4 , the present invention provides a technical solution: a chemical material screening machine for chemical production, including a screening machine body 1, a feeding hopper 2 is provided on the screening machine body 1, a screening mechanism and a recycling mechanism are provided on the inner wall of the screening machine body 1, a vibration mechanism is provided on the screening mechanism, and the vibration mechanism is installed on the outer surface of the screening machine body 1;

[0024] The screening mechanism includes a fixed plate 3, the fixed plate 3 is installed on the inner wall of the screening machine body 1, a guide rod 31 is installed on the fixed plate 3, a sieve plate 32 is slidably installed on the guide rod 31, the sieve plate 32 is adapted to the feeding hopper 2, a return spring 36 is sleeved on the guide rod 31, one end of the return spring 36 is installed on the fixed plate 3, and the other end of the return spring 36 is installed on the sieve plate 32. When using the sieve plate 32 in the screening machine body 1 to screen chemical raw materials, due to the inclined setting of the sieve plate 32, it is convenient for the raw materials to have a larger contact area with the sieve plate 32 after falling from the feeding hopper 2. At the same time, the knocking block 43 intermittently knocks the sieve plate 32 and pushes the sieve plate 32 upward, and then the return spring 36 pulls the sieve plate 32 back to its original position from a high place, so that the raw materials falling on the sieve plate 32 can be quickly and conveniently screened by the setting of the knocking block 43 and the sieve plate 32.

[0025] Refer to Figures 1-3, in the present utility model, a first discharge pipe 33 is installed on one side of the screening machine body 1. The first discharge pipe 33 is adapted to the classification sieve plate 32. A limiting groove 34 is formed on the first discharge pipe 33. A baffle plate 35 is movably installed on the inner wall of the limiting groove 34. By sliding the baffle plate 35 in the limiting groove 34 of the first discharge pipe 33, the large-sized raw materials screened by the classification sieve plate 32 can be intermittently discharged from the first discharge pipe 33, avoiding the continuous opening of the first discharge pipe 33 and the discharge of raw materials from the first discharge pipe 33 without filtration, which may lead to repeated filtration of the raw materials.

[0026] Refer to Figures 2-3 , in the present utility model, the vibration mechanism includes a driving rotating shaft 4. The driving rotating shaft 4 is rotatably installed on the screening machine body 1. A knocking block 43 is installed on the driving rotating shaft 4. The knocking block 43 is in contact with the bottom side of the classification sieve plate 32. A servo motor 41 is installed on one side of the driving rotating shaft 4. An installation frame 42 is installed on the servo motor 41. The installation frame 42 is installed on the outer surface of the screening machine body 1. The servo motor 41 drives the driving rotating shaft 4 to rotate, and the driving rotating shaft 4 drives the knocking block 43 to rotate, so as to intermittently knock the classification sieve plate 32, thereby enabling the classification sieve plate 32 to vibrate and accelerating the screening of chemical raw materials. At the same time, when the knocking block 43 knocks the classification sieve plate 32, the classification sieve plate 32 will be lifted upward. When the classification sieve plate 32 is lifted, the return spring 36 will be stretched. When the knocking block 43 moves away from the classification sieve plate 32, the restoring force of the return spring 36 can conveniently drive the classification sieve plate 32 to return to its original position, and due to the instability of the return spring 36, the classification sieve plate 32 keeps shaking in the vertical direction, thereby further accelerating the screening of chemical raw materials.

[0027] Refer to Figure 3 , in the present utility model, the recycling mechanism includes a discharge block 5. The discharge block 5 is installed on the inner wall of the bottom side of the screening machine body 1. A second discharge pipe 51 is installed on the outer surface of one side of the screening machine body 1. The discharge block 5 is adapted to the second discharge pipe 51. Due to the trapezoidal shape of the discharge block 5, the raw materials can conveniently fall onto the discharge block 5 after being screened by the classification sieve plate 32, and the inclination of the discharge block 5 enables the raw materials to quickly and conveniently flow out from the second discharge pipe 51.

[0028] The working principle is as follows: When using the screening machine body 1 to screen chemical raw materials, the chemical raw materials are added into the screening machine body 1 from the feed hopper 2 on the screening machine body 1. Before the raw materials fall, the switch of the servo motor 41 is started. The servo motor 41 drives the driving rotating shaft 4 to rotate, and the driving rotating shaft 4 drives the knocking block 43 to rotate, so as to intermittently knock the classification sieve plate 32. When the raw materials are added from the feed hopper 2 onto the classification sieve plate 32, the knocking block 43 is used to add to the classification sieve plate 32, so that the raw materials on the classification sieve plate 32 can be screened conveniently and quickly. At the same time, when the knocking block 43 knocks the classification sieve plate 32, the classification sieve plate 32 will be lifted upward. When the classification sieve plate 32 is lifted upward, the return spring 36 on the guide rod 31 will be stretched. When the knocking block 43 moves away from the classification sieve plate 32, the classification sieve plate 32 can be quickly pulled back to its original position by the restoring force of the return spring 36, and the instability of the return spring 36 can also be used to make the return spring 36 bounce continuously in the vertical direction, so as to further accelerate the screening of the raw materials. At the same time, the raw materials remaining on the classification sieve plate 32 after screening will be discharged into the first discharge pipe 33 from the bottom end of the classification sieve plate 32. When the screening in the screening machine body 1 is completed, the baffle plate 35 in the limit groove 34 is opened, and the raw materials accumulated in the first discharge pipe 33 can be conveniently discharged outward. At the same time, it can fall through the sieve holes on the classification sieve plate 32 onto the discharge block 5 and be discharged from the inclined bottom end of the discharge block 5.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
